A cutting mechanism 3 for cutting the wire is also provided between the wire clamping mechanism 2 and the wire end clamping mechanism 4. Several wires pass through the wire clamping mechanism 2, the cutting mechanism 3 and the wire end clamping mechanism 4 in sequence.

[0028] The wire material clamping and feeding mechanism 2 includes a supporting plate 21 vertically slidingly arranged on the frame 1, a baffle 22 fixedly arranged on the supporting plate 21, and a cylinder 1 23 fixedly arranged on the supporting plate 21. The output end of the cylinder 1 23 is fixed with a pressure block 24 arranged toward the baffle 22, and the wire passes through between the baffle 22 and the pressure block 24. Reinforcement plates 25 for fixing the baffle 22 are also respectively provided on both sides of the pressure block 24 on the supporting plate 21. A plurality of through holes for allowing the wire material to pass through are arranged in an array on the reinforcement plate 25. The frame 1 is provided with a cylinder 26, and the supporting plate 21 is connected to the output end of the cylinder 26. The through holes on the reinforcement plate 25 in the wire material clamping and feeding mechanism 2 have the effect of guiding the wire material, and the reinforcement plates 25 of the fixed baffle 22 are close to each other to achieve the clamping and pressing effect of the wire material. The movement of the cylinder 26 realizes the conveying effect of the wire material, and the wire material clamping and feeding mechanism 2 realizes the multifunctional effects of guiding, clamping, pressing and conveying the wire material.

[0029] The wire end clamping mechanism 4 includes a supporting block 41 vertically slidingly arranged on the frame 1, a pneumatic finger 42 fixedly arranged on the supporting block 41, and a clamping claw 43 connected to the output end of the pneumatic finger 42. The clamping claw 43 can be detachably clamped on the ends of several wires. A cylinder three 44 is provided on the frame 1, and the supporting block 41 is connected to the output end of the cylinder three 44.

[0030] Furthermore, the welding mechanism 5 is an ultrasonic welding machine, and the welding head 51 and welding seat 52 of the ultrasonic welding machine are set on both sides of the plurality of wires for sliding in opposite directions (the welding mechanism 5 adopts ultrasonic welding equipment in the prior art. Ultrasonic welding is a fast, clean and effective assembly process used to assemble and process thermoplastic plastic accessories and some synthetic components. It is used for bonding between plastic products, bonding plastic products to metal accessories and bonding other non-plastic materials. The welding mechanism 5 is implemented using existing technology and will not be described in detail here).

[0031] Furthermore, the wire traction mechanism 6 includes a support platform 61 horizontally slidably arranged on the frame 1, and a cylinder four 62 arranged on the support platform 61. The output end of the cylinder four 62 is connected to a traction rod 63. The traction rod 63 is used to pull a number of wires between the welding head 51 and the welding seat 52. The side of the traction rod 63 is provided with an annular groove corresponding to the wire. The annular groove is provided to limit the wire when the traction rod 63 pulls the wire to prevent the wire from sliding on the traction rod 63.

[0034] The specific working process and principle of this utility model:

[0035] The wire is passed through the reinforcing plate 25 of the wire clamping and feeding mechanism 2 and the knife seat 31 of the cutting mechanism 3 in sequence to complete the threading installation of the wire;

[0036] Start the device by operating the controls in console 9, see Figure 3 、 Figure 5 , start the cylinder 1 23 of the wire clamping and feeding mechanism 2, clamp the wires onto the baffle 22 through the pressing block 24, start the cylinder 2 26, and convey the wires clamped by the pressing block 24 and the baffle 22 downward through the knife holder 31 and the cutter 32, and expose them below the cutter 32;

[0037] See also Figure 4 , start the cylinder 3 44 to extend the telescopic end, the bearing block 41 drives the pneumatic finger 42 to move upward until the clamping claw 43 passes over the wire and extends to the outside of the wire, start the cylinder 1 23 of the wire clamping and feeding mechanism 2, the telescopic end of the cylinder 1 23 drives the pressure block 24 to retract to release the wire, then start the pneumatic finger 42, the clamping claw 43 firmly clamps the wire, and then start the cylinder 3 44 to retract the telescopic end to drag the wire downward to the set length through the clamping claw 43;

[0038] See also Figure 2 、 Figure 6 , start the cylinder 4 62, the telescopic end of the cylinder 4 62 drives the traction rod 63 to retract, then start the cylinder 5 64, the telescopic end of the cylinder 5 64 retracts, driving the carrier 61 to move toward the wire end clamping mechanism 4, when the traction rod 63 passes over the wire clamped by the clamping claw 43, the cylinder 5 64 stops moving, start the cylinder 4 62 again, the telescopic end of the cylinder 4 62 drives the traction rod 63 to extend, and finally start the cylinder 5 64 to extend the telescopic end, the side of the traction rod 63 pulls the wire between the wire end clamping mechanism 4 and the cutting mechanism 3 over the welding mechanism 5 and then stops, at this time the wire is folded between the welding seat 52 and the welding head 51;

[0039] It can be understood that after the welding head 51 is lowered to contact the wire, the cylinder 1 23 is activated again, and the wire is pressed against the baffle 22 through the pressure block 24, and then the cylinder 2 26 is activated to tighten the wire upward. At this time, the wire between the welding head 51 and the welding seat 52 is in a tensioned state, so as to prepare for welding;

[0040] Specifically, in this embodiment, the welding seat 52 is raised, the welding head 51 and the welding seat 52 are both in close contact with the wire, and the welding mechanism 5 is started to perform a welding operation on the folded wire;

[0041] After the wire welding is completed, the cylinder 6 33 is started to extend the cutter 32 to cut the wire from the lower side of the knife seat 31, and the end of the wire is still in the knife seat 31, separated from the welded wire, completing the folding welding operation of the wire.

[0042] The cooperation between the wire clamping mechanism 2 and the wire end clamping mechanism 4 makes the feeding and conveying of the wires more efficient and faster. The cooperation between the wire pulling mechanism 6 and the wire clamping mechanism 2 makes the folding of the wires more efficient. The wire clamping mechanism 2 stretches the wires, making the placement accuracy of the wires in the welding mechanism 5 higher, thereby making the welding effect of the welding mechanism 5 better. The folding and welding process of the polymer wires is efficient and fast.

[0043] The knife holder 31 of the cutting mechanism 3 is used to guide several wires, and the cutter 32 is used to cut several wires at the same time. The cutting mechanism 3 has a higher efficiency in cutting the wires, and when the wire clamping mechanism 2 conveys the wires downward, the knife holder 31 guides the wires, thereby improving the stability of wire transportation.

[0044] Embodiment 2: The frame 1 is also provided with a feeding mechanism 7 for feeding the wire clamping mechanism 2. The feeding mechanism 7 includes a roller frame 71 provided on the frame 1, which rotates the active roller 72 and the driven roller 73 provided on the roller frame 71 respectively. A number of wires pass between the active roller 72 and the driven roller 73. The frame 1 is also provided with a motor 74, and the output end of the motor 74 is connected to the active roller 72.

[0045] A guide tray 8 is provided between the wire pulling mechanism 6 and the wire clamping and feeding mechanism 2 . Guide portions 81 are provided at both ends of the guide tray 8 . Several wires are conveyed to the wire clamping and feeding mechanism 2 by the guide portions 81 of the guide tray 8 .

[0046] Several wires pass between the active roller 72 and the driven roller 73 of the feeding mechanism 7. After the motor 74 of the feeding mechanism 7 is started, the active roller 72 connected to the motor 74 rotates to transport the wires to the guide tray 8. After passing through the guide tray 8, the wires pass through the wire clamping mechanism 2. Through the cooperation of the active roller 72 and the driven roller 73 in the feeding mechanism 7, the feeding of the wires is more stable. The guide tray 8 plays a role of load transition and buffering for the wires. The wire clamping mechanism 2 is more stable, efficient, safe and reliable when conveying the wires.
