[0020] Specifically, when harness processing, wire rod from pay-off stand 110 respectively enters two wire entry distribution mechanisms 200, wire rod is arranged and distributed using wire entry distribution mechanism 200, then double pulling wire is carried out by left pulling wire clamp mechanism 140 and right pulling wire clamp mechanism 150, and wire rod in two wire entry distribution mechanisms 200 is pulled respectively, realizes double wire supply, when wire rod is pulled to wire cutting mechanism 300, two wire cutting mechanisms 300 carry out fixed-length cutting operation to wire rod, and wire rod after cutting is sent by adaptive wire feeder, and next processing operation is carried out to wire rod;

[0021] And the end of wire that is set is subsequently clamped by left pulling wire clamp mechanism 140 and right pulling wire clamp mechanism 150, under the drive of belt linear module 130, wire rod after cutting is pulled to specified position along double linear guide 120, to complete the whole terminal harness processing process. This overall structure is reasonable in layout, and each component is closely matched with each other, effectively improves the processing efficiency and quality of terminal harness;

[0022] And the belt linear module 130 of the both ends of double linear guide 120 drives left pulling wire clamp mechanism 140 and right pulling wire clamp mechanism 150 to carry out pulling operation by belt, and the belt transmission mode of belt linear module 130 has the advantages of high transmission efficiency and simple structure, which can effectively guarantee the efficiency of double pulling wire.

[0023] In the embodiment, the incoming wire branch mechanism 200 includes a linear lead screw module 210 fixedly installed on the side of the support rod 100, a sliding seat of the linear lead screw module 210 is slidingly connected with a wire branch sliding plate 220, a front surface of the wire branch sliding plate 220 is installed with a plurality of wire straightening guide wheel sets 230 for guiding and looping and tension adjustment of the wire, one end of the wire branch sliding plate 220 is installed with an L-shaped incoming wire support plate 240, one end of the incoming wire support plate 240 is embedded with a plurality of incoming wire guide rings 250, the other end of the incoming wire support plate 240 is installed with a plurality of incoming wire guide wheels 260 at the connection with the wire branch sliding plate 220, the other end of the wire branch sliding plate 220 is installed with a plurality of wire passing pipes 270, the wire passing pipes 270 are opposite to the wire straightening guide wheel sets 230 in position, the wire straightening guide wheel sets 230 are opposite to the incoming wire guide wheels 260 in position, and the incoming wire guide wheels 260 are opposite to the incoming wire guide rings 250 in position.

[0024] Specifically, the wire discharged from the wire reel 110 first passes through the incoming wire guide rings 250, enters the incoming wire guide wheels 260, is guided by the incoming wire guide wheels 260, and then loops the plurality of guide wheels of the wire straightening guide wheel sets 230 in sequence, so as to guide the wire to the correct path and avoid deviation of the wire from the predetermined incoming wire direction, and the tension adjustment of the wire during incoming wire is realized by the tension adjustment between the guide wheels of the wire straightening guide wheel sets 230, so that the tension of the wire is kept within a suitable range, and the neatness of the wire during the incoming wire process is ensured, and then the wire finally enters the wire passing pipes 270 to provide support for the left and right wire pulling mechanisms 140 and 150.

[0025] The linear lead screw module 210 can drive the wire branch sliding plate 220 to adjust the height, so that the wire passing pipes 270 can be at a suitable height, and the left and right wire pulling mechanisms 140 and 150 can conveniently pull the wire.

[0026] In the embodiment, the middle part of the wire passing pipe 270 is installed with a wire branch pressing mechanism 280, the wire branch pressing mechanism 280 includes a hole-inserted rod 281 penetrating through the wire passing pipe 270, a T-shaped wire pressing block 282 is slidingly arranged at the middle part of the hole-inserted rod 281, the T-shaped wire pressing block 282 is further arranged in a T-shaped hole 283 inside the wire passing pipe 270, one end of the hole-inserted rod 281 is installed with a hand screw 284, the other end of the hole-inserted rod 281 is installed with a ring nut 285, and the ring nut 285 is arranged with a spring 286 sleeved on the hole-inserted rod 281 between the ring nut 285 and the T-shaped wire pressing block 282.

[0027] Specifically, when the wire passes through the wire tube 270, the operator needs to adjust the pressing force of the T-shaped wire pressing block 282 on the wire according to the type, diameter and processing requirements of the wire and other factors by rotating the manual screw rod 284. When the manual screw rod 284 is rotated, the hole plug rod 281 is pushed, and due to the limiting action of the annular nut 285, the hole plug rod 281 drives the T-shaped wire pressing block 282 to move in the T-shaped hole 283 of the wire tube 270, thereby pressing the wire. The spring 286 can play a buffering and adjusting role. If the pressing force of the T-shaped wire pressing block 282 on the wire is too large, the spring 286 is compressed, thereby avoiding excessive extrusion or damage to the wire. If the pressing force is too small, the spring 286 will provide a certain elastic force to promote the T-shaped wire pressing block 282 to continue to press the wire, ensuring that under different processing conditions, the wire head can be effectively prevented from separating from the wire tube 270 after being cut off, thereby improving the stability of the device operation and the overall efficiency of the wiring harness processing.

The clamping arm of the first pneumatic clamp jaw 330 is provided with a wire cutting blade 350.

[0029] Specifically, when the wire cutting operation is needed, the control system sends an instruction to the first air cylinder 320. The telescopic end of the first air cylinder 320 acts so that the first pneumatic clamp jaw 330 can stably move in a straight line along the guide slide rail 340 and approach the wire. Then the clamping arm of the first pneumatic clamp jaw 330 is controlled to close until the wire cutting blade 350 contacts the wire and applies sufficient pressure to quickly cut off the wire.

[0030] After the wire cutting is completed, the first air cylinder 320 is retracted according to the instruction of the control system, driving the first pneumatic clamp jaw 330 to return to the initial position along the guide slide rail 340, waiting for the next wire cutting operation.
