[0070] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0071] like Figures 1 to 3 As shown, this embodiment provides a wire processing device, which includes a wire feeding mechanism 1, a cutting and stripping mechanism 2 and a wire pulling mechanism 3. The wire feeding mechanism 1 includes a conveying unit 11 and a wire guiding unit 12, and the cutting and stripping mechanism 2 includes a wire skin cutting unit 23 and a wire twisting unit 22. The conveying unit 11 is arranged between the wire guiding unit 12 and the wire skin cutting unit 23.

[0072] The conveying unit 11 can reciprocate along the first direction, and the conveying unit 11 moves to the first preset position toward the wire guide unit 12. The conveying unit 11 is used to clamp the wire 100 and carry the wire 100 to the wire skin cutting unit 23 to move to the second preset position. The wire skin cutting unit 23 is used to cut the wire skin of the first end of the wire 100, and the wire twisting unit 22 is used to knead the wire core of the first end of the wire 100 after the wire skin is cut, and obtain the first wire 101. The wire pulling mechanism 3 is used to pull the first end of the first wire 101 to move to the third preset position in a direction away from the wire twisting unit 22, and the wire skin cutting unit 23 is used to cut the wire skin of the second end of the first wire 101, and the wire twisting unit 22 is used to knead the wire core of the second end of the first wire 101 after the wire skin is cut, and obtain the second wire 102. Among them, the second wire 102 is the final wire required for production, and its length and shape meet the production requirements.

[0073] The wire feeding mechanism 1 automatically feeds the conductor 100 to the cutting and stripping mechanism 2. The wire skin cutting unit 23 of the cutting and stripping mechanism 2 is used to cut the wire skin of the conductor 100. The wire twisting unit 22 rubs the wire core of the conductor 100 to remove the wire skin. The wire pulling mechanism 3 pulls the first conductor 101, and then the second conductor 102 can be obtained after the wire skin is removed at both ends and the first-level wire core is rubbed. The wire skin is removed at both ends of the second conductor 102, and the two ends of the second conductor 102 are rubbed into a twist shape. The wire feeding mechanism 1, the cutting and stripping mechanism 2 and the wire pulling mechanism 3 in the conductor processing device provided in this embodiment cooperate with each other to realize the automatic feeding and automatic stripping of the conductor 100, and the automatic removal of the second conductor 102 after the two ends are stripped and the core is rubbed, which meets the automated production requirements and conforms to the production rhythm of the magnetic ring conductor system assembly.

[0074] The cutting and stripping mechanism 2 also includes a wire core cutting unit 21, and a wire twisting unit 22 is arranged between the wire core cutting unit 21 and the wire skin cutting unit 23. When the wire pulling mechanism 3 pulls the first end of the first wire 101 to move to a third preset position in a direction away from the wire twisting unit 22, the wire core cutting unit 21 is used to cut the first wire 101 and cut to form the second end of the first wire 101. The wire core cutting unit 21 is provided to cut the wire 100 into a required length. For example, the wire 100 is a wire arranged in a roll. The first end of the wire 100 passes through the wire guiding unit 12. The conveying unit 11 carries the first end of the wire 100 to the wire skin cutting unit 23 and the wire twisting unit 22. The wire skin cutting unit 23 cuts the wire skin of the first end of the wire 100. The wire twisting unit 22 kneads the wire core of the first end of the wire 100 after the wire skin is cut, and obtains the first wire 101. The wire pulling mechanism 3 pulls the first end of the first wire 101 to move to a third preset position in a direction away from the wire twisting unit 22. The wire core cutting unit 21 cuts the first wire 101 and cuts to form the second end of the first wire 101. The wire skin cutting unit 23 cuts the wire skin of the second end of the first wire 101. The wire twisting unit 22 is used to knead the wire core of the second end of the first wire 101 after the wire skin is cut, and obtain the second wire 102. The length of the second wire 102 meets the production requirements, and the wire skins of both ends of the second wire 102 are removed and twisted into a twist shape.

[0075] In order to improve production efficiency, two wire skin cutting units 23 are set, and the core cutting unit 21 and the wire twisting unit 22 are set between the two wire skin cutting units 23. The core cutting unit 21 cuts the core of the first wire 101 placed between the two wire skin cutting units 23, and the wire skin cutting unit 23 cuts the wire skin of the first wire 101 placed between the two wire skin cutting units 23. The wire twisting unit 22 kneads the core placed between the two wire skin cutting units 23 and with the wire skin cut off, and simultaneously obtains a second wire 102 and another first wire 101 with the wire skin cut at the first end and the wire core twisted into a twist shape.

[0076] like Figure 1 and Figure 4 As shown, in some embodiments, the wire 100 is transported along a first direction, the wire guiding unit 12 is used to guide the wire 100 transported to the transport unit 11, and the transport unit 11 transports the wire 100 to the cutting and stripping mechanism 2 along the first direction.

[0077] Alternatively, see Figure 5 and Figure 6As shown, the wire guide unit 12 includes a guide seat 121, a first guide roller 122 and a second guide roller 123. The first guide roller 122 is provided with a first wire groove 1221 along the circumferential direction, and both ends of the first guide roller 122 are rotatably connected to the guide seat 121. The second guide roller 123 is arranged in a one-to-one correspondence with the first guide roller 122, and the second guide roller 123 is provided with a second wire groove 1231 along the circumferential direction, and the second wire groove 1231 is arranged opposite to the first wire groove 1221. Slide blocks 124 are respectively provided on opposite sides of the guide seat 121. The slide blocks 124 are connected to the guide seat 121 in a sliding manner along the second direction. Both ends of the second guide roller 123 are connected to the slide blocks 124 for rotation. An elastic member 125 is connected between the slide block 124 and the guide seat 121. The elastic member 125 is used to make the second guide roller 123 press against the first guide roller 122. The gap formed between the first wire groove 1221 and the second wire groove 1231 is used for the wire 100 to pass through, and the wire 100 is limited in the first wire groove 1221 and the second wire groove 1231 to avoid the wire 100 from deflecting during the conveying process. In addition, the second guide roller 123 elastically presses against the first guide roller 122. In the process of conveying the wire 100, the spacing between the first guide roller 122 and the second guide roller 123 is adjustable to avoid the wire jamming during the conveying process of the wire 100, thereby ensuring the smoothness of the conveying of the wire 100. The number of the first wire grooves 1221 and the second wire grooves 1231 is set according to the number of the transmission wires 100, and is not specifically limited here.

[0078] There are multiple first guide rollers 122 and multiple second guide rollers 123 respectively, and the multiple first guide rollers 122 and the multiple second guide rollers 123 are arranged along the first direction.
