[0002] Terminal crimping is a way of connecting wires and terminals during the wire assembly process. A certain mechanical external force is applied to the exposed copper wire at the end of the insulator and the terminal bite to tightly combine the two materials, thereby achieving the purpose of electrical conductor or firm connection. Therefore, precise crimping tools can ensure good crimping quality. In the prior art, crimping devices generally include manual tools, semi-automatic crimping equipment and fully automatic crimping equipment.

[0053] When the first incomplete gear 441 meshes with the transmission gear 46 through a group of teeth with a smaller number of teeth, the drive shaft 514 moves backward from the front end of the rotating frame 511 along the path formed by the conveyor belt 513, and drives the sliding frame 521 to move synchronously from front to back by cooperating with the straight groove 523. The guide shaft 5253 moves backward from the front end of the track in the return groove 532 close to the corresponding side of the wiring harness, thereby driving the clamping head 5252 at the upper end of each group of clamping slides 5251 to first clamp the wiring harness in the corresponding fixed-length U-shaped frame 331, and synchronously drive the wiring harness to move backward a specific distance, so that the copper wire at the end of the wiring harness can accurately and stably enter the crimping part of the corresponding terminal. At this time, the group of teeth with a smaller number of teeth on the first incomplete gear 441 is just disengaged from the transmission gear 46, and the drive shaft 514 also stops moving synchronously.

[0054] When the first incomplete gear 441 is meshed with the transmission gear 46 through a group of teeth with a larger number of teeth, the copper wire at the end of each group of wiring harnesses has been crimped with the corresponding terminal, and the rear end of each group of wiring harness terminals has been accurately aligned with the mounting holes in the terminal shell delivered by the feeding mechanism 7. The driving shaft 514 then drives the sliding frame 521 to make the clamping head 5252 continue to drive the wiring harness and the terminal to move backward a certain distance until the guide shaft 5253 moves to the rear end of the track in the return groove 532 close to the corresponding side of the wiring harness.

[0055] When the guide shaft 5253 moves to the rear end of the track in the return groove 532 close to the corresponding wiring harness side, under the action of the spring between the clamping slide plate 5251, the guide shaft 5253 moves from the track close to the corresponding wiring harness side to the track away from the corresponding wiring harness side at the rear end of the return groove 532, and the clamping head 5252 releases the clamping of the wiring harness, so that it can be unloaded with the terminal shell; under the continuous drive of the drive shaft 514, the guide shaft 5253 moves from the track in the return groove 532 away from the corresponding wiring harness side to the track away from the corresponding wiring harness side. The rear end of the track moves to the front end, at this time, a group of teeth with a larger number of teeth on the first incomplete gear 441 is just disengaged from the transmission gear 46, and at the same time, the spring between the clamping slides 5251 is in a stretched state, and the clamping slides 5251 then drive the guide shaft 5253 under the action of the spring to reset to the front end of the track in the return groove 532 close to the corresponding wiring harness side. This clamping and delivery method can realize adaptive clamping limit and clamping limit release, thereby ensuring stable delivery of wiring harnesses and terminals and stable unloading.

[0059] When the copper wires at the end of each set of wiring harnesses accurately and stably enter the crimping part of the corresponding terminal, at this time, under the drive of the driving gear 43, the second driven gear 452 drives the first bevel gear 453 to rotate, and the first bevel gear 453 drives the second bevel gear 611 and the second incomplete gear 612 to rotate through meshing transmission, and the second incomplete gear 612 drives the linkage gear 613 and the linkage shaft 614 to rotate a specific angle through meshing transmission, so that the linkage shaft 614 passes through the rod between the connecting plate 622 The connecting plate 622 and the crimping die 624 are pressed downward, and the crimping die 624, in cooperation with the crimping support plate 314, tightly crimps the copper wire at the end of the wire harness with the crimping part of the corresponding terminal until the second incomplete gear 612 is disengaged from the linkage gear 613. Under the action of the spring between the connecting plate 622 and the crimping frame 621, the crimping die 624 moves upward and disengages from the crimping part of the terminal, thereby completing the crimping of the wire harness and the terminal while preventing obstruction to the secondary delivery of the wire harness terminal.

[0060] See also Figure 1 , Figure 2 and Figure 4The feeding mechanism 7 includes a feeding rack 71, a first cylinder rod 72, a second cylinder rod 73, a guide rod 74 and a moving assembly 75; the feeding racks 71 are symmetrically fixedly arranged at the left and right ends of the bottom plate 1, wherein the first cylinder rod 72 is fixedly arranged on the left side of the left feeding rack 71, wherein the second cylinder rod 73 is fixedly arranged on the rear side of the right feeding rack 71 through a plate, guide rods 74 are fixedly arranged between the feeding racks 71, and a moving assembly 75 is arranged between the feeding racks 71.

[0061] The moving assembly 75 includes a moving seat 751, a docking seat 752 and a limiting slide 753; the telescopic end of the first cylinder rod 72 is fixedly provided with a moving seat 751 which is slidably connected to the guide rod 74, the upper surface of the moving seat 751 is fixedly provided with a docking seat 752 which is engaged with the docking elastic clip 22, and the left and right sides of the moving seat 751 are symmetrically fixed with limiting slides 753 which are slidably engaged with the slide groove 24 through plates, and a card slot is opened in the moving seat 751.

[0062] Start the drive motor 42 to make the drive gear 43 intermittently drive the clamping head 5252 to accurately and stably deliver the copper wire at the end of each group of wire harnesses to the crimping position of the corresponding terminal. During the first delivery of the wire harness, the limiting slide 753 in the slide slot 24 can stably limit the front end of the terminal, thereby ensuring the stable docking of the wire harness and the terminal. Then, under the synchronous drive of the drive gear 43, the crimping mold 624 completes the crimping of each group of copper wires with the corresponding terminal. At the same time, during the crimping process, the moving seat 751 drives the terminal shell in the slot to move to the right under the push of the first cylinder rod 72. When the wire harness and the terminal are crimped, the corresponding mounting holes in the terminal shell are connected to each group of upper U-shaped frames 311 and lower U-shaped frames under the drive of the first cylinder rod 72. The terminals in 313 are stably aligned, and the stability of the docking assembly of the wiring harness terminals and the terminal shell can be ensured by the clamping cooperation between the docking socket 752 and the docking elastic clamp 22. Then the clamping head 5252 delivers each set of wiring harnesses and terminals forward again until each set of terminals is fully inserted into the corresponding mounting holes, thereby completing the assembly of the wiring harness terminals and the terminal shell. This operation mode not only realizes fast and stable intermittent secondary delivery of the wiring harnesses and terminals through a unified drive, but also realizes fast and stable crimping of the wiring harnesses and terminals through a unified drive during the two delivery processes, which greatly simplifies the operating steps of the overall crimping and assembly operations, and through the synchronous delivery and crimping of multiple sets of wiring harnesses and terminals, the efficiency of the overall operation process can be greatly improved.

[0063] After the wiring harness terminal is installed into the mounting hole in the terminal shell, the first cylinder rod 72 can continue to push the movable seat 751 to move rightward to the right feeding rack 71, and the terminal shell can be quickly pushed out of the slot through the second cylinder rod 73 to complete the unloading.
