[0002] With the widespread application of electrical connectors in all walks of life, the requirements for electrical connectors of various specifications and models are getting higher and higher. The electrical connection performance of electrical connectors depends to a large extent on the connection between internal pins, sockets and wires.

The shift block head is hinged on the side of the shift block seat that is facing the direction of the unloading mechanism by the laser wire stripping mechanism. A torsion spring is passed through the hinge axis between the shift block head and the shift block seat. The torsion springs respectively abut the shift block head and the shift block seat. A limiting step facing downward and opening toward the shift block seat is provided below the shift block head on one side facing the shift block seat. The torsion spring elastically abuts the shift block head in a state of crimping the upper step surface on the inner side of the limiting step and the upper end surface of the shift block seat. The side of the shift block head facing away from the shift block seat corresponds to the wire feeding rack. An inward-inclined inclined A side transfer seat is arranged on the side transfer guide rail, and a side transfer track is arranged inwardly on the upper end of the side transfer seat, and the side transfer track corresponds to the front and rear transfer tracks in a state where a movable wire feeder is guided between the side transfer track and the front transfer track, and between the side transfer track and the rear transfer track; a rear transfer conveyor belt supporting and conveying the wire feeder is arranged in the rear transfer track, and a pulling cylinder is arranged on one side of the corresponding unloading mechanism of the rear transfer track, and the pulling cylinder is extended outwardly to connect the pulling rod corresponding to the wire feeder that is fed from the side transfer seat into the rear transfer track.

[0013] Furthermore, four locking through holes are respectively provided on the side of the front transfer track not facing the laser wire stripping mechanism, corresponding to the laser wire stripping mechanism, the crimping mechanism, the crimping detection mechanism and the unloading mechanism. The front transfer track outside the four locking through holes is externally connected to four locking mechanisms.

[0014] During operation, the wire coil is connected to the unwinding roller of the unwinding seat behind the wire feeding rack, and the wire coil is unwound from the feeding rotating seat to the rear output shaft, guided and tensioned on the feeding rotating seat, and the wire connection head is sent out to send the wire outward; the transfer linear guide operation of the closed-loop transfer track drives the shifting block assembly to move along the laser stripping mechanism toward the unloading mechanism, and the shifting block head of the shifting block assembly pushes the wire feeding rack to move. After any wire feeding rack corresponds to the laser stripping mechanism, the upper and lower laser heads on the upper and lower laser operating racks are adjusted and moved perpendicular to the wire release direction by the laser moving cylinder, and the outer layer of the wire is laser cut for the part that needs to be removed at the front end of the wire. After the laser cutting is completed, the stripping feeding cylinder is controlled to drive the stripping rack to feed toward the front end of the wire, and at the same time, the two-way cylinder is controlled to move toward the center through the upper and lower stripping knives. The seat drives the upper and lower wire stripping knives to close the switch at the corresponding laser cutting position to complete the cutting and separation. Combined with the negative pressure suction of the wire stripping suction tube, the outer layer of the separated wire is sucked and collected outside to realize the laser wire stripping operation; then, the transfer linear guide operation in the front transfer track of the closed-loop transfer track is controlled to drive the shift block assembly to move along the unloading mechanism toward the laser wire stripping mechanism. The shift block head of the shift block assembly overcomes the force of the torsion spring and is blocked by the previous wire feed rack and pressed down to pass. After passing, the shift block head is reset under the action of the torsion spring and abuts against the previous wire feed rack. The five wire feed racks corresponding to the laser stripping mechanism, the wire stripping detection mechanism, the crimping mechanism, the crimping detection mechanism and the unloading mechanism can be pushed in sequence according to the above process to complete the laser wire stripping operation on the wire feed rack corresponding to the laser stripping mechanism. At the same time, the subsequent wire stripping detection mechanism completes the laser wire stripping detection, the crimping structure completes the socket docking guide and crimping, the crimping detection mechanism completes the crimping detection, and the unloading mechanism completes the wire unloading. When the wire feeder that has completed the laser wire stripping operation moves toward the wire stripping detection mechanism, the subsequent wire feeders move backward in sequence, and the wire feeder corresponding to the unloading mechanism is dialed into the transfer track on the inner side of the transfer seat on the side of the transfer guide rail at the end of the front transfer track through the dial block assembly, and the transfer guide rail moves backward to the corresponding position on one side of the rear transfer track, and the wire feeder is pulled into the rear transfer track through the pulling cylinder through the pulling rod and transported to the other side position on the rear transfer conveyor belt of the rear transfer track, and the pushing cylinder is lifted by pushing the lifting cylinder and the wire feeder is pushed into the side of that side by the pushing cylinder through the pushing rod. The wire feeder is moved to the transfer rail and sent to the front end of the front transfer rail along with the side transfer rail. When the shift block assembly in front of the wire feeder at the corresponding station of the laser wire stripping mechanism is sequentially sent backward, a shift block assembly in front of the corresponding shift block assembly of the wire feeder extends to the front of the wire feeder in the side transfer rail and sends it to the position of the laser wire stripping mechanism. When the shift block assembly is reset on the transfer linear guide rail, it is always pressed against the wire feeder. After the shift block head of the shift block assembly passes through the wire feeder and is reset, the six wire feeders in the closed-loop transfer rail can be driven by the six shift block assemblies to ensure that the positions corresponding to the laser wire stripping mechanism, the wire stripping detection mechanism, the crimping mechanism, the crimping detection mechanism and the unloading mechanism always correspond to the wire feeder that has completed the corresponding operation, thereby completing the automated cycle operation.In the wire stripping detection mechanism, the wire stripping detection probe CCD visual detection head is used to monitor whether there is an unremoved outer layer of the wire at the front end of the wire of the required stripping length, and the wire stripping detection structure on the workstation is recorded. If the wire is not stripped or the stripping is incomplete, the wire feeder of the workstation moves backward in sequence but does not complete the crimping operation and crimping detection, and controls the unloading linear guide rail on the unloading mechanism to feed the unloading pneumatic chuck to clamp, cut and unload to the defective collection tank. If the wire stripping is complete, the wire feeder moves backward to the crimping mechanism position for crimping operation; during the crimping operation, the crimping feed cylinder drives the crimping operation cylinder and the casing clamp to feed toward the front end of the wire after stripping, and the jaws of the closing clamp close the loose inner core wire of the wire and feed it into the jaws of the casing clamp. At the same time, the jack that needs to be plugged is placed in the vibration disk of the jack feeding mechanism, and the jack is fed with the vibration disk to one end of the jack feeding track, and the front and rear jack sensing probes sense the jack. The jack in the hole feeding track meets the feeding control of the vibration plate. When the jack is sent to the other end of the jack feeding track, it is directly sent into the reversing groove of the reversing support head of the jack reversing mechanism. The CCD visual detection head detects the direction of the jack. When the direction of the jack is wrong, the reversing rotary cylinder rotates and reverses. After the direction of the jack is correct, the reversing linear guide drives the reversing support head to correspond to one end of the jack feeding track and continuously pushes the jack in the jack feeding track. The jack with the correct direction is sent from the other end of the jack feeding track to the feeding support chuck in the jack feeding device, and is pressed down and clamped by the feeding clamping chuck. The jack is driven by the feeding feeding cylinder to feed toward the crimping mechanism, and the corresponding sleeve of the jack is sent onto the inner core wire of the wire in the casing jaws. The feeding support chuck and the feeding clamping chuck retract and reset, and then the crimping operation cylinder is controlled to pull the clamp legs of the casing clamp to close the casing clamp jaws to complete the crimping operation of the wire and the jack.The wire feeding rack that has completed the crimping operation is sent to the crimping detection mechanism, and the CCD visual inspection head of the crimping detection mechanism detects the crimping status of the wire and the socket. At this time, the rotary clamping cylinder drives the rotary working rack to feed toward the rear end of the wire feeding rack, so that the rotary clamping connector on the rotary working rack is clamped into the clamping interface at the rear end of the wire feeding rack, and then the rotary working cylinder is controlled to drive the feeding rotary seat to rotate through the rotary clamping connector, thereby driving the wire connection head and the wire connection head passing through the wire connection head to complete the rotation of the crimped socket. The visual inspection is completed by rotating more than one circle. If the visual inspection finds that the crimping is incomplete, such as incomplete crimping at multiple points on the crimping circle or insufficient insertion guide depth, the unloading mechanism will be used later. The wire is sent to the defective collection tank. After visual inspection, the wire feeder moves back to the unloading structure for unloading. The unloading mechanism controls the unloading linear guide to feed the unloading pneumatic chuck to clamp the front end of the wire and move back to pull out the required wire length. The bidirectional cylinder is controlled at the cutting mechanism position to drive the cutting knife to cut the wire. The unloading pneumatic chuck clamps the wire crimped by the socket to the finished product collection tank and releases it. The finished product collection tank completes the collection. The cutting mechanism position is aligned with the front end of the wire working on the laser stripping mechanism, thereby ensuring that the wire after each unloading extends out of the wire connector to a fixed length. The cutting operation can be completed by controlling the unloading pneumatic chuck to clamp and pull the length to meet the required cutting length. ;

[0015] In the laser wire stripping mechanism, notches are provided on the cutting edges of the upper and lower wire stripping knives, which can ensure that the outer layer of the wire is effectively cut off without damaging the inner core wire, and at the same time facilitate the suction of the cut outer layer of the wire by negative pressure; when the wire feeder is fed along with the shifting block assembly, at the workstations corresponding to the laser wire stripping mechanism, the crimping mechanism, the crimping detection mechanism and the unloading mechanism, the locking opening on the wire feeder is pushed by the locking cylinder of the locking mechanism to pass through the locking through hole and clamp into the locking opening, thereby ensuring the positioning of the wire feeder at each workstation, which is conducive to ensuring the stability and accuracy of the laser wire stripping operation, crimping operation, crimping detection operation and unloading operation.
