The terminal crimping mechanism 11 is used to crimp the terminal onto the wire core. The terminal loading mechanism 2 is used to convey the terminal to the crimping seat 111. The wire clamping mechanism 3 is used to clamp the wire harness. The Y - axis linear driving mechanism 4 is used to drive the stripping mechanism 5, the waterproof plug rotary feeding mechanism 8, and the waterproof plug clamping mechanism 9 to move back and forth. The stripping mechanism 5 is used to strip the insulating skin at one end of the wire core. The waterproof plug feeding mechanism 6 is used to supply waterproof plugs to the waterproof plug picking mechanism 7. The waterproof plug picking mechanism 7 is used to transfer the waterproof plug from the waterproof plug feeding mechanism 6 to the waterproof plug rotary feeding mechanism 8. The waterproof plug rotary feeding mechanism 8 is used to transfer the waterproof plug to the waterproof plug clamping mechanism 9. The waterproof plug clamping mechanism 9 is used to sleeve the waterproof plug onto the wire core. The strip cutting mechanism 12 is used to cut the terminal waste strip.

[0031] Its working principle is that the terminal material roll is installed on the terminal feeding mechanism 1, and the single wire core of the wire harness can be clamped by the wire clamping mechanism 3 by manual feeding, and the stripping mechanism 5 is driven to move forward by the Y-axis linear driving mechanism 4, and the stripping mechanism 5 strips off the insulation skin at one end of the wire core, and the waterproof plug is supplied to the waterproof plug picking mechanism 7 by the waterproof plug feeding mechanism 6, and then the waterproof plug is transferred to the waterproof plug rotating feeding mechanism 8 by the waterproof plug picking mechanism 7, and then the waterproof plug is transferred to the waterproof plug clamping mechanism 9 by the waterproof plug rotating feeding mechanism 8. After the waterproof plug clamping mechanism 9 clamps the waterproof plug, the wire core will be aligned with the inner hole of the waterproof plug, and the waterproof plug will be moved to the waterproof plug through the Y-axis linear driving mechanism 4.

When the terminal is transported to the riveting seat 111, the waterproof plug will be located directly above the riveting seat 111, and the terminal can be riveted on the waterproof plug through the riveting mechanism 112. After the terminal riveting is completed, the wire clamping mechanism 3 releases the wire core, and the next wire core can be rotated for processing. The automation of wire core stripping, waterproof plug insertion, and terminal riveting can be automatically completed, which greatly saves manpower and improves production efficiency.

The guide posts 301 are movably disposed in the guide grooves, and a return spring abutting between the top end of the guide groove and the end panel is sleeved on the guide posts 301. Specifically, initially, the left clamping arm 36 and the right clamping arm 37 are in an open state. An operator places a wire core between the left clamping arm 36 and the right clamping arm 37. By driving the second L-shaped slider 34 to move left or right through the first X-axis driving cylinder 35, the turntable 32 can be driven to rotate forward or backward, which will drive the first L-shaped slider 33 to move left or right, so as to realize the opening or closing action of the left clamping arm 36 and the right clamping arm 37, and realize the release and clamping operations of the wire core. When terminal riveting is performed, the Z-axis linear driving mechanism 112a drives the riveting head mounting seat 112b to move downward.

Then, the second servo motor 56 drives the peeling push plate 55 to move forward. The left dialing arm 53 and the right dialing arm 54 will rotate and drive the left peeling arm 51 and the right peeling arm 52 to close, so that the two peeling knives 510 close and cut the insulating skin at the peeling position of the wire core. Then, the Y-axis linear drive mechanism 4 drives the peeling mechanism 5 to retreat, and the cut insulating skin on the wire core can be peeled off from the wire core. After the second servo motor 56 drives the peeling push plate 55 to reset, the left dialing arm 53 and the right dialing arm 54 will reset under the pulling force of the first tension spring, and the two peeling knives 510 return to the open state.

Then, the first Y-axis driving cylinder 71 drives the picking needle 73 to horizontally move until it is aligned with the receiving pipe 84, and then the Z-axis driving cylinder 72 drives the picking needle 73 to move downward to sleave the waterproof plug on the picking needle 73 onto the receiving pipe 84, completing the transfer of the waterproof plug. The rotation driving mechanism 82 drives the rotating arm 81 to rotate to the horizontally forward state, and the pick-and-place cylinder 83 drives the receiving pipe 84 to extend forward, and then the waterproof plug clamping mechanism 9 clamps the waterproof plug, completing the transfer of the waterproof plug to the waterproof plug clamping mechanism 9.
