[0021] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0022] like Figures 1 to 4 As shown, in this embodiment, a wire stripping and twisting mechanism includes a laser machine 1, a wire limiting shaft 2, a stripping module 3, a winding rotation motor 4 and a winding pneumatic clamp 5. A wire limiting cylinder 6 is installed in the middle of the laser machine 1. The wire limiting shaft 2 is connected to the driving end of the wire limiting cylinder 6. A winding stand 7 is connected to the driving end of the stripping module 3. The winding rotation motor 4 is fixed on the winding stand 7. The winding rotation motor 4 controls the rotation of the winding pneumatic clamp 5.

[0023] Moreover, the wire limiting cylinder 6 is located between the upper laser head 13 and the lower laser head 14 of the laser machine 1. The wire is placed in front of the laser machine 1, and the wire limiting cylinder 6 controls the wire limiting shaft 2 to extend forward to support the front end position of the wire. Then the wire limiting cylinder 6 retracts the wire limiting shaft 2, and the laser machine 1 controls the upper laser head 13 and the lower laser head 14 to cut the outer skin of the wire. Then the stripping module 3 controls the winding stand 7 to move forward to the wire, and the winding pneumatic clamp 5 clamps the cut outer skin, and the wire is twisted under the action of the winding rotating motor 4, and the outer skin is pulled out along the retreat action of the stripping module 3.

[0024] A laser front and rear slide rail 8 and a laser moving motor 9 are arranged along the front and back below the laser machine 1. The driving end of the laser moving motor 9 is connected to a laser moving lead screw 10. A laser front and rear slider 11 and a laser moving nut 12 are installed at the bottom of the laser machine 1. The laser front and rear slider 11 slides on the laser front and rear slide rail 8, and the laser moving lead screw 10 is threadedly connected to the laser moving nut 12.

[0025] When the wire with the outer skin is fixed, the laser moving motor 9 controls the laser moving screw 10 to rotate, so that the laser machine 1 with the laser moving nut 12 moves forward along the laser front and rear slide rails 8, and laser skin cutting is performed at the place where the wire is fixed.

[0026] A material receiving box 15 is fixed to the front end of the peeling module 3, and a scraper cylinder 16 is installed in the material receiving box 15. The driving end of the scraper cylinder 16 is vertically connected to a scraper 17. After the outer skin is twisted out, the winding pneumatic clamp 5 releases the outer skin, and the outer skin will fall into the material receiving box 15 for collection. If the outer skin remains on the winding pneumatic clamp 5, the scraper cylinder 16 controls the scraper 17 to rise, and the outer skin is scraped off when the winding pneumatic clamp 5 retreats.

[0027] An upper winding synchronous wheel 18 and a lower winding synchronous wheel 19 are rotatably connected on the winding seat 7, the driving end of the winding rotary motor 4 is key-connected to the upper winding synchronous wheel 18, the fixed end of the winding pneumatic clamp 5 is key-connected to the lower winding synchronous wheel 19 with a winding shaft 20, and a winding synchronous belt 21 is transmission-connected between the upper winding synchronous wheel 18 and the lower winding synchronous wheel 19. In terms of controlling the rotation of the winding pneumatic clamp 5, the winding rotary motor 4 controls the upper winding synchronous wheel 18 and the lower winding synchronous wheel 19 to transmit through the winding synchronous belt 21, and the winding pneumatic clamp 5 brings out the outer skin twisted wire under the rotation of the winding shaft 20.

[0028] A winding photoelectric sensor 22 is installed on the winding stand 7, and a winding induction sheet 23 is connected to the winding shaft 20. The winding induction sheet 23 is connected to the winding photoelectric sensor 22 for signal connection. The number of turns during twisting is counted by the winding photoelectric sensor 22 sensing the winding induction sheet 23.

[0029] A peeling limit sensor 24 is installed on one side of the peeling module 3, and a peeling sensor sheet 25 is fixed on one side of the winding seat 7. The peeling sensor sheet 25 is connected to the signal of the peeling limit sensor 24. In the process of the peeling module 3 controlling the forward and backward movement of the winding seat 7, in order to ensure the position of the winding pneumatic clamp 5 grabbing the outer skin, a signal is provided through the position of the peeling limit sensor 24.

[0030] A control screen 26 and a display panel 27 are installed at the upper end of the laser machine 1 . The entire peeling and winding process is controlled by the control screen 26 , and specific data is displayed on the display panel 27 .
