While the outer skin and the inner skin of the wire harness are cut, the traction assembly drives the wire harness to be pulled back, so that the cutting assembly cooperates with the traction assembly to peel off the inner skin and the outer skin of the corresponding part of the rear end of the wire harness; Then the clamping assembly drives the cut wire harness into the cutting assembly, and according to the different shearing feed amounts, the outer and inner skins of the front end of the wire harness are cut off. While the outer and inner skins of the wire harness are cut off, the clamping assembly drives the wire harness to be pulled back, so that the cutting assembly cooperates with the clamping assembly to peel off the inner and outer skins of the corresponding parts of the front end of the wire harness. After the front end of the wire harness is cut, the clamping assembly drives several wire harnesses to move and flip, so that the front end of the wire harness is aligned with the liquid box, and then the clamping assembly drives the front end of the wire harness to be inserted into the liquid box for tinning; During traction, cutting and tinning, the upper plate assembly simultaneously transports the attachment plate to the pasting assembly.

[0051] When the wire harness needs to be pulled to the cutting assembly 5, the first cylinder 314 drives the clamping plate 315 to move, so that the elastic sleeve 316 is located in the matching hole 3151. At this time, the matching hole 3151 clamps the wire harness, and then the cylinder pushes the traction frame 31 to move, so that the wire harness enters the cutting assembly 5; After the clamping assembly 4 clamps the wire harness, the first cylinder 314 drives the clamping plate 315 away from the elastic sleeve 316, and then the clamping assembly 4 pulls the wire harness back, so that the wire harness can slide in the traction frame 31 and pass through the cutting assembly 5; During the cutting process, the first cylinder 314 drives the clamping plate 315 to move, so that the elastic sleeve 316 is re-positioned in the matching hole 3151 and clamps the wire harness, so that the traction frame 31 can drive the wire harness to move different feed amounts into the cutting component 5, and cooperate with the cutting component 5 to cut and peel off the inner and outer skins at the rear end of the wire harness.

The waste collection box 55 is lifted and lowered by a first servo drive unit 56. The lead screw in the first servo drive unit 56 is a bidirectional threaded lead screw. The first servo drive unit 56 controls the lifting seat 52 and the waste collection box 55 to move relatively away from or close to each other. A first cutting seat 57, a second cutting seat 58 and a third cutting seat 59 are installed on the waste collection box 55. The first cutter 521 corresponds to the first cutting seat 57, the second cutter 531 corresponds to the second cutting seat 58, and the third cutter 522 corresponds to the third cutting seat 59.

[0056] When cutting the wire harness, the lifting seat 52 descends, the waste collection box 55 rises, and the second cutter 531 and the second cutting seat 58 cooperate to cut the wire harness. At this time, a space for the wire harness to pass through is left between the first cutter 521 and the first cutting seat 57, and a space for the wire harness to pass through is left between the third cutter 522 and the third cutting seat 59; The process of cutting and stripping the rear end of the wire harness is as follows: Then the traction frame 31 drives the rear end of the wire harness to retreat and extend the rear end of the wire harness to a certain length below the lifting seat 52. At this time, the lifting seat 52 descends again, and the waste collection box 55 rises again, so that the third cutter 522 and the third cutting seat 59 just cut the outer skin of the rear end of the wire harness.

[0057] The process of cutting and stripping the front end of the wire harness is as follows: The first clamp 414 and the second clamp 415 drive the cut wire harness to extend under the lifting seat 52, the lifting seat 52 descends, and the waste collection box 55 rises, so that the first cutter 521 and the first cutting seat 57 just cut the outer skin of the front end of the wire harness, and then the first clamp 414 and the second clamp 415 drive the wire harness to be pulled back, the first cutter 521 and the first cutting seat 57 cooperate to peel the outer skin from the front end of the wire harness, and the lifting seat 52 and the waste collection box 55 are reset; Then, driven by the second servo drive unit 47, the first clamp 414 and the second clamp 415 drive the cut wire harness to extend under the lifting seat 52 again, the lifting seat 52 descends, and the waste collection box 55 rises, so that the first cutter 521 and the first cutting seat 57 just cut the inner skin of the front end of the wire harness; Furthermore, when the wire harness inner skin is cut, the first transverse moving block 54 and the second transverse moving block 511 move laterally relative to each other, so that the first rubbing board 53 and the second rubbing board 510 grind off the wire harness inner skin, ensuring that the wire harness inner skin is completely disconnected.

[0058] Finally, the first clamping and second clamping jaws 415 pull the wire harness back, the first cutter 521 and the first cutting seat 57 cooperate to peel the inner skin from the front end of the wire harness, and the lifting seat 52 and the waste collection box 55 are reset.

[0063] When several wire harnesses are cut, the second sliding seat 71 moves to the bottom of the clamping assembly 4, and then the fifth cylinder 73 drives the second finger cylinder 74 to rise, so that the wire harness falls into the slot 761 of the two clamping plates 76, and then the second finger cylinder 74 is started, and the two claws of the second finger cylinder 74 approach each other, so that the two clamping plates 76 clamp the wire harness together, and then the second sliding seat 71 cooperates with the fifth cylinder 73 to drive the wire harness to move, and place the wire harness on the attachment plate under the pasting assembly 8.

[0064] like Fig.14The pasting assembly 8 includes a transverse plate 81, which is slidably arranged at the left end of the workbench 1.

The tape is located between the laminating plate 814 and the first pressing wheel 86 to ensure that the tape will not be displaced after cutting.

[0065] After the upper line assembly 7 grabs the wire harness to the attachment plate, as the transverse plate 81 moves, the first pressing wheel 86, the second pressing wheel 87 and the third pressing wheel 88 are all attached to the attachment plate. During the movement of the transverse plate 81, the adhesive tape is unwound from the unwinding wheel 83, passes around the guide roller 813 and the first pressing wheel 86, and then adheres to the attachment plate and the wire harness, and then the second pressing wheel 87 and the third pressing wheel 88 cooperate to press tightly; When an attachment plate is full of wiring harnesses, the sixth cylinder 85 retracts to drive the flip plate 84 to rotate, and the flip plate 84 drives the first pressure wheel 86 to rotate, so that the first pressure wheel 86 is away from the attachment plate, and then the seventh cylinder 89 drives the cutting knife 812 to pass through the cutting opening 811 and is located below the first pressure wheel 86. After the cutting knife 812 passes through the tape, the third finger cylinder 810 drives the cutting knife 812 to cut the tape, and then the cutting knife 812 and the first pressure wheel 86 are reset. At this time, the end of the tape is still located below the first pressure wheel 86. When the first pressure wheel 86 is reset, the tape can still be smoothly pasted on the attachment plate, and the next wiring harness and attachment plate can be continued to be pasted, thereby realizing the function of automatic pasting and cutting of tape.
