Heralded as one of the greatest guitarists of all time. SRV created a legacy that will have a lasting influence on all future generations of guitarists. His broad appeal and raw talent made him one of the world's most influential electric blues guitarists. Also on this bill is another great guitarist, Jeff Beck.
He was one of the three noted guitarists— the others being Eric Clapton and Jimmy Page— to have recorded with the band Beck was ranked the 14th on Rolling Stone Magazine's list of the Greatest Guitarists, and his music has spanned genres ranging from blues-rock, heavy metal, jazz fusion and a blend of guitar-rock and electronica. Beck has earned wide critical praise and four Grammy awards for Best Rock Instrumental Performance, and has been nominated for induction into the Rock and Roll Hall of Fame.
Jeff Beck is still highly influential with many modern guitarists, who cite him as a major influence on their playing.

Wrinkles unless otherwise noted are the sleeve and not the photo. Large black spot is on scanner. Not photo. The key 36 is positioned to correspond to a tuned orientation of the ferrule An outer grip or connector 38 mounts over the ferrule housing A hub assembly 40 is fixedly mounted to the ferrule The hub assembly 40 spring biases the ferrule in a forward direction.
The connector 30 also includes a dust cap 42 that covers the front of the ferrule 32 , and a crimp sleeve 37 and boot 44 mounted at the rear of the connector In addition to tuning, insertion and return loss can be improved by polishing the end faces of the ferrules. During the polishing process, the ferrules are commonly held in a fixture, and the end faces are pressed against a rotating polishing wheel or disk. Frequently, the end faces are polished to form a polished surface oriented along a plane that is perpendicular with respect to the longitudinal axis of the fibers.
However, for some applications, the end faces are polished to form a surface aligned at an oblique angle with respect to the longitudinal axis of the fibers. Other process steps are also undertaken to complete the manufacture of fiber optic connectors. For example, after polishing, the end faces of the connector ferrules are often cleaned. Other steps include tuning the connectors, testing the connectors for insertion and return loss, and assembling the various components of the connectors.
Historically, the manufacture of fiber optic connectors has been quite labor intensive. Originally, connectors were individually manually polished and individually manually moved through the various processing steps.
Manufacturing efficiency improved with the more prevalent use of multi-connector fixtures e. While multi-connector fixtures have improved manufacturing efficiencies, further improvements in the area of automation are needed.
One aspect of the present disclosure relates to equipment having features adapted to facilitate automating various steps in the process of manufacturing a fiber optic connector. A variety of advantages of the invention will be set forth in part in the description that follows, and in part will be apparent from the description, or may be learned by practicing the invention.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed. The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate several aspects of the invention and, together with the description, serve to explain the principles of the invention. A brief description of the drawings is as follows:. While the invention is amenable to various modifications and alternative forms, the specifics there have been shown by way of example in the drawings and will be described in detail below.
It is to be understood, however, that the intention is not to limit the invention to a particular embodiment. On the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the scope of the invention as defined by the appended claims. In the following detailed description, references are made to the accompanying drawings that depict various embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized, and that structural and functional changes may be made without departing from the scope of the present invention.
First Embodiment of Automated Connectorization System. The system is adapted for use in processing connectorized fiber optic cables e. The connectorized cables typically include fiber optic connectors e. The bare fibers can be housed within bare fiber support sleeves that protect and prevent bending of the bare fibers, and also facilitate optically coupling the bare fibers to test equipment during processing of the cables After processing of the cables , the bare fibers can be used to provide field terminations or to provide splices with other cables.
The processing stations shown include a polishing station , a cleaning station , a tuning station , a test station , an SC connector adjust station , an FC connector key press station , and a dust cap installation station The system also includes a conveying system for conveying the connectorized optical cables through the various processing stations.
One or more processing units e. The conveying system includes a carrier adapted for carrying any number of optical cables ranging from a single optical cable up to hundreds of optical cables. The carrier is shown carrying fixtures for securing the connectors The fixtures include clamps for holding the connectors as the connectors are processed at the various processing stations.
The clamps preferably hold the connectors with ferrules of the connectors exposed so that end faces of the ferrules can be readily accessed for processing. The fixtures also include receiver sockets for receiving the bare fiber support sleeves When mounted within the receiver sockets , the ends of the bare fiber support sleeves are exposed to facilitate optically coupling the bare fibers to test equipment during processing. The fixtures of the carrier are preferably adapted to hold a plurality of connectors during processing.
In one non-limiting embodiment, the fixtures of the carrier can have a capacity of least 72 connectors The stations are preferably standalone units that are assembled together to form the assembly line. The modularity of the stations allows the stations to be readily removed, added, or rearranged along the assembly line. For example, each station can include wheels to allow for ease in the rearrangement of the different stations.
While seven stations have been shown in the embodiment of FIG. In use, the carrier initially conveys the connectorized optical cables to the polishing station The polishing station preferably includes a plurality of substations each corresponding to a different polishing function. For example, the polishing substations can be configured with polishing mediums e. The polishing station can include one or more drive mechanisms for moving the polishing mediums relative to the ferrule end faces of the connectors being processed.
For example, the drive mechanisms can spin, oscillate or otherwise move the polishing mediums relative to the ferrule end faces Alternatively, the end faces of the connectors can be moved relative to the polishing mediums. After the ferrule end faces of the connectors have been polished, the carrier conveys the connectorized cables to the cleaning station At the cleaning station , residue or other foreign material deposited on the ferrules of during the polishing stage is preferably removed.
In one embodiment, steam and blasts of air e. After cleaning, the carrier conveys the fixtures to the tuning station At the tuning station , the connectors e.
The connectors are tuned by inputting light into the connectors at each rotational increment, and comparing the relative amount of light that is output from the bare fiber ends at each increment.
The rotational orientation of the tuned position i. After tuning, FC connectors can be rotated within the fixtures to place the key locations at known rotational positions that are coordinated with subsequent processing steps e.
Alternatively, in the case of SC connectors, the key locations can be stored in memory for use at the SC connector adjust station From the tuning station , the carrier moves the connectorized cables to the test station At the test station , each of the connectors is tested for insertion loss and return loss to ensure each of the connectors complies with predetermined insertion loss and return loss standards.
The connectors are tested by inputting light through the connectors and measuring the quantity of light output through the bare fiber ends Information concerning connector failure is stored in memory for use during subsequent processing operations.
If SC connectors are being processed, the carrier moves from the test station to the SC connector adjust station If FC connectors are being processed, the carrier moves from the test station , past the SC connector adjust station , to the FC connector key press station If ST or D4 connectors are being processed, the carrier moves from the test station , past both the SC connector adjust station and the FC connector key press station , to the dust cap station At the SC connector adjust station , the ferrule of each SC connector e.
After the SC connector adjustment process has been completed, the carrier carries the SC connectors past the FC connector key press station to the dust cap station At the FC connector key press station , keys e. The pre-orientation of the rotational positions of the FC connectors at the tuning station ensures that the keys are properly oriented at the optimal tuned or key locations. Thereafter, the carrier moves the FC connectors to the dust cap station At the dust cap station , dust caps e.
In some embodiments, dust caps are only applied to those connectors that were successfully processed through system For example, dust caps can be placed on only those connectors that receive a passing rating at test station In this manner, during subsequent processing, the presence of a dust cap indicates that the connectors are ready for subsequent processing e.
The absence of a dust cap alerts the operator that the connector has failed in some respect, and alerts the operator to remove the connector for re-processing.
Second Embodiment of Automated Connectorization System. The system includes a plurality of modular processing stations arranged in an assembly line. Similar to the previous embodiment, the processing stations include a polishing station , a cleaning station , a tuning station , a test station , an SC connector adjust station , an FC connector key press station and a dust cap station , all of which are described further below. The system also includes a cart conveying unit for conveying a cart from station to station.
See FIGS. The cart is adapted for carrying one or more connectorized fiber optic cables The system further includes fixture assemblies that can be mounted to and detached from the cart For clarity, only a few of the fixture assemblies are shown mounted to the cart The fixture assemblies each include a tuning and test fixture for clamping boots of the connectors , and a polishing fixture having nests for supporting the ferrules of the connectors The tuning and test fixtures also define receptacles for receiving the bare fiber support sleeves mounted to bare fiber ends of the cables The system further includes a fixture conveyor for conveying the fixture assemblies from station to station along the assembly line.
The fixture conveyor is a separate conveyor from the cart conveyor However, the operation of the fixture conveyor is coordinated with the operation of the cart conveyor such that the fixture assemblies and their corresponding cart move in a side-by-side relationship from station to station.
The system includes a main system controller that coordinates the operation of the fixture conveyor with the operation of the cart conveyor The main system controller interfaces with controllers at each of the stations to integrate each station into the overall system. In certain embodiments, the main systems controller can include a personal computer with keyboard access.
In general use of the system , a spool of fiber optic cable is placed on the cart while the cart is off-line from the cart conveyor Connectors of the fiber optic cables are then clamped within the fixture assemblies , and the bare fiber support sleeves are inserted within receptacles defined by the fixture assemblies The fixture assemblies are then secured to the cart After securing the fixture assemblies to the cart , the cart is manually wheeled to the cart conveyor The cart then engages the cart conveyor and is conveyed toward the polishing station Prior to reaching the polishing station , the fixture assemblies are disconnected from the cart and engaged with the fixture conveyor The fixture conveyor then conveys the fixture assemblies to the polishing station for polishing of the ferrules At the end of the polishing station, the polishing fixtures of fixture assemblies are stripped from the tuning and test fixtures to provide more ready access to the connectors during subsequent processing steps.
The tuning and test fixtures are then moved by the fixture conveyor to subsequent processing stations to allow the connectors to be processed e. Typically, the tuning and test fixtures are stopped at stations where processing is desired to provide sufficient time for processing. As described with respect to the embodiment of FIG. The functions performed at each of the stations can be similar to those described with respect to the embodiment of FIG. Movement of the cart is preferably coordinated with the movement of the fixture on the conveyor The conveyor preferably moves the fixtures in a stepwise motion i.
The cart conveyor preferably moves the cart in a stepwise motion that corresponds to the stepwise motion generated by the conveyor In this manner, the fixtures which carry the connectors and the cart which carries the bulk of the cable remain in a side-by-side relationship throughout the various processing steps.
After the dust cap station , the fixtures are disengaged from the conveyor and re-connected to the cart , and the cart is disengaged from the cart conveyor and manually wheeled to a location for further processing of the connectors For example, at a subsequent location, outer grips can be pressed on the connectors Thereafter, the connectors can be removed from the fixtures , and the fixture assemblies can be re-assembled and reloaded with a next batch of connectors The cart can then be wheeled back to the start of the cart conveyor to initiate processing of the next batch of connectors A plurality of carts , each including a plurality of connectors mounted in fixture assemblies , can be processed by system For example, a plurality of carts can be sequentially loaded into system so that each station of system is eventually occupied at a given point in time.
Referring now to FIGS. The polishing fixture is detachably mounted to the underside of the tuning and test fixture A latching arrangement, such as a pair of spring latches , is used to secure the polishing fixture relative to the tuning and test fixture The polishing fixture also includes alignment pins that fit within openings defined by the tuning and test fixture to maintain alignment between the two fixtures , Referring to FIGS.
The resilient arms are biased together and interlocked with a retaining member provided on the tuning and test fixture The polishing fixture can be detached from the tuning and test fixture by pulling downwardly on the polishing fixture with sufficient force to flex the arms of the latches apart such that the arms disengage from the retaining member The polishing fixture of the fixture assembly includes three ferrule nests sized to receive ferrules of the connectors The ferrules protrude downwardly beyond the nests such that the end faces of the ferrules are exposed for polishing.
In addition, the ferrule nests form a close tolerance fit as the ends of ferrules extend below the fixture Each ferrule nest also includes a boss with end See FIG. The boss functions to center the ferrule of each connector and is sized so that the end of the ferrule for both FC connectors and SC connectors extends an equal distance below the fixture Specifically, as shown in FIG.
In contrast, an end of housing 34 of FC connector b contacts the base of the nest In this manner, end faces of both the SC connector a and FC connector b extend an equal distance below fixture As shown in FIGS. The extension provides a location where the polishing fixture can be clamped by a polishing machine at the polishing station Referring to FIG.
The clips interlock with the V-notches to prevent the fixture assemblies from inadvertently rotating on or disengaging from the mounting pins of the cart The tuning and test fixture also include three clamps best shown in FIGS.
Each of the clamps includes two clamp members between which the boots of the connectors are clamped. Each of the clamp members includes a recessed mid-region The recessed mid-region defines receptacles e. The recessed mid-regions have generally V-shaped cross-sections with the widths of the recessed mid-regions enlarging as the recessed mid-regions extend in a downward direction.
A pair of resilient members e. The resilient members facilitate gripping the boots of the connectors The clamp members are spring biased toward one another i. The clamp members can pivot slightly to accommodate connectors with boots of differing dimensions and tapers. See, for example, FIG. In addition, when the clamp members are moved from the closed to the open position, the clamp members move slightly in an upward direction during the beginning of movement to the open position so that tension on the connector is released prior to release of the boot of the connector.
The tuning and test fixture further includes clamp control knobs for manually opening and closing the clamps In manual operation, as illustrated in FIGS. Knob a can be rotated a quarter turn to temporarily lock clamp a in the open position. In an automatic operation, internal components of fixture can be actuated to open clamps a , b , and c without requiring control knobs a , b , and c to be manually pulled upward.
The tuning and test fixture further includes a receiver defining the receptacle for receiving one of the bare fiber support sleeves , which is illustrated in FIGS. The receiver extends through the main body of the tuning and test fixture and includes a lower portion that is accessible from the underside of the main body When the bare fiber support sleeve is mounted within the receiver , the ends of the bare fibers are accessible from the underside of the tuning and test fixture for allowing the fibers to be optically connected to a test structure such as a remote test head for use in insertion loss and return loss testing.
The tuning and test fixture further includes upper and lower pins and The upper pin projects upwardly from the main body of the fixture , and the lower pin projects downwardly from the main body of the fixture The pins , are adapted to engage the fixture conveyor A fiber holder including ferrules is configured to receive and hold stranded bare fiber. In use, bare stranded fiber is extended through channel formed in base portion and into fiber holder Previously stripped ends of the stranded fiber are positioned to extend through ferrules Then, the top portion is pivoted toward the base portion until in the position illustrated in FIG.
Next, the stripped ends of the fibers that extend from ferrules are cleaved. In one embodiment, a cleaver having product no. CT, manufactured by Fujikura Ltd. Once the fibers are cleaved, the bare fiber support sleeve is positioned in the tuning and test fixture , as shown in FIGS. In this position, the ferrules of support sleeve are accessible below the fixture If, instead of stranded fiber, ribbon fiber is being processed, a similar support sleeve can be used. However, for ribbon fiber, no ferrules are required because the ribbon structure provides adequate support for the fibers.
In addition, for ribbon fiber, the fiber can be both stripped and cleaved once the fiber has been placed in the support sleeve. The cart includes a base A rear portion of the base defines a platform for supporting a spool of fiber optic cable. Rollers are provided on the platform for facilitating loading and unloading spools of fiber optic cable to or from the platform The sides of the platform are enclosed by side walls and the front of the platform is enclosed by a front wall The back of the platform is open to facilitate loading fiber optic spools onto the platform.
Handles are provided at the top sides of the side walls for facilitating maneuvering of the cart With respect to the spools carried by the cart , the spools typically range in diameter from 12 inches 36 inches. The spools can carry anywhere from one fiber optic cable to hundreds of fiber optic cables.
In the case where a large number of fiber optic cables are wrapped about the spool, the fibers are typically bundled within one or more bundling sheathes. Sub-bundles can be provided within the main sheathed bundles. The fiber optic cables can range in length from a few feet to hundreds of feet. While the cables will typically be provided on spools, it will be appreciated that for short length cables, spools may not be needed.
The casters include pivoting caster wheels The caster wheels include central grooves A pair of racks or ladders is also mounted to the underside of the base The ladders provide structure for allowing the cart conveyor to engage the cart The cart further includes a front cable management structure that projects forwardly from the front wall The cable management structure includes an upright front panel Cable management structures such as spools for managing excess cable and clamps for clamping cables are mounted to the front panel Two cable clamps are mounted to the top of the upright panel The clamps are adapted for clamping a sheathed portion of a bundle of fiber optic cables.
The sheathed portion of the bundles is preferably clamped at the clamps , and extensions of the fiber optic cables bundled within the sheath are typically fanned downwardly from the clamps with connectorized ends of the fiber optic cables being clamped within the fixture assemblies Excess length of cable corresponding to the connectors being processed, as well as extra cables having connectors that have already been processed or are soon to be processed, can be managed by wrapping such cables around the spools The cart further includes a fixture mount The fixture mount includes a plurality of mounting pins adapted to be received within the rear openings of the tuning and testing fixtures The depicted mount is adapted for mounting 24 fixture assemblies However, it will be appreciated that the capacity of the mount can be varied without departing from the principles of the disclosure.
The fixture mount also includes resilient retention clips that engage the notches in the tuning and test fixtures to prevent the fixtures from inadvertently disengaging from the pins The fixture mount further includes a handle for retracting the fixture mount to disengage the fixture assemblies from the cart after the fixture assemblies have been engaged by the fixture conveyor By pivoting the handle , the pins are withdrawn from the rear openings of the tuning and test fixtures to disengage the fixture assemblies from the cart As the fixture mount is retracted, the retaining clips flex upwardly to allow the fixture assemblies to be disengaged from the cart The cart further includes a bin for receiving and storing the polishing fixtures As will be described below, after the polishing processes have been completed at the polishing station , the polishing fixtures are stripped from the tuning and test fixtures After the polishing fixtures have been stripped, the polishing fixtures slide by gravity down a ramp and into the bin for storage.
Subsequently, the polishing fixtures are removed from the bin and recoupled to fixtures for processing the next batch of connectors. The cart conveyor is depicted in FIG. Center guides are located within each of the tracks When the cart is conveyed along the tracks , the grooves of the wheels ride along the center guides The cart conveyor also includes a drive mechanism for moving the cart along the tracks It will be appreciated that the drive mechanism can have any number of different configurations.
In the depicted embodiment, the drive mechanism includes a pneumatically powered walking beam drive In other embodiments, the drive mechanism can include a chain drive, a stepper motor drive, a rack and pinion drive, or any other drive suitable for conveying the cart in a controller manner.
The walking beam drive includes a pair of parallel beams a , b having lugs for engaging the ladders on the underside of the cart Vertical pneumatic cylinders raise and lower the beams a , b and horizontal pneumatic cylinders move the rails horizontally. The left beam a is preferably moved in a square pattern.
For example, beam a is raised e. The right beam b can be moved in a similar pattern. Alternatively, the beam b can simply be raised and lowered to selectively engage right ladder the cart For example, the right beam b can be raised when the left beam a is lowered to prevent unintentional movement of the cart , and then lowered when the lugs of the left beam a are in engagement with the cart The screw drives can be powered by a drive mechanism see FIG.
The screw drives are vertically offset from one another i. As shown in FIG. By rotating the screw drives , the fixture , including the tuning and test fixture and polishing fixture , is conveyed along the screw drives
