[0045] like Figure 1 and Figure 2 As shown, the auxiliary wire feeding assembly 700 includes a pretensioner 720. The output end of the pretensioner 720 is connected to one end of the pretensioning shaft. The pretensioning shaft is rotatably connected to the fixed bracket through a bearing.

[0046] like Figure 1 and Figure 2 As shown, the wire feeding assembly 300 includes a wire feeding frame 301, on which the wire is wound. The wire feeding frame 301 is rotatably connected to a fixed plate 303 via a pivot. Three wire feeding rollers 302 are arranged at the discharge end of the wire feeding frame 301, and are rotatably connected to the fixed plate 303. Adjacent wire feeding rollers 302 are staggered in height, and the three wire feeding rollers 302 can fully unwind the wire.

[0047] like Figure 1 and Figure 2 As shown, a first coating mechanism 920 is provided between the second winding drive assembly 500 and the wire feeding assembly 300, and a second coating mechanism 930 is provided between the auxiliary wire feeding assembly 700 and the first winding drive assembly 400. The first coating mechanism 920 and the second coating mechanism 930 can coat the surface of the passing wire with the desiccant acetone.

[0048] like Figure 4 As shown, the first coating mechanism 920 includes an immersion box 921 containing an adhesive release agent, acetone. A lifting cylinder 922 is positioned above the opening of the immersion box 920. The drive end of the lifting cylinder 922 is connected to a lifting bracket 923, and a lifting pressure roller 924 is rotatably connected to the lifting bracket 923. The lifting cylinder 922 can push the lifting pressure roller 924 downwards, pressing the passing wire into the adhesive release agent acetone immersed in the immersion box 921. A wire guide roller 925 is provided on each of the left and right sides of the immersion box 920. The second coating mechanism 930 has the same structure as the first coating mechanism 920.

[0049] like Figure 1 As shown, a drying mechanism 940 is provided on one side of the first winding drive assembly 400. The drying mechanism 940 is capable of drying the coil in the main winding assembly 100 connected to the first winding drive assembly 400. The drying mechanism 940 includes a dryer 941 fixed on the housing 910. The air outlet of the dryer 941 is connected to a drying head 943 through a drying pipe 942. The drying head 943 faces the coil in the main winding assembly 100.

[0050] The working principle of this invention is: when performing double-layer coil winding, such as Figure 2As shown, the auxiliary winding assembly 200 is mounted on the drive end of the second winding drive assembly 500, and the wire coil to be wound is mounted on the unwinding frame 301. First, the wire end on the unwinding assembly 400 is pulled onto the auxiliary winding assembly 200 for winding after passing through three unwinding rollers 302. Then, the second winding drive assembly 500 drives the auxiliary winding assembly 200 to rotate, and the wire forming the second layer of the coil is first wound onto the auxiliary winding assembly 200. After the second layer of the coil on the auxiliary winding assembly 200 is wound, the auxiliary winding assembly 200 is removed from the second winding drive assembly 500 and mounted on the auxiliary fixing bracket 800, so that the auxiliary winding assembly 200 and the main winding assembly 100 maintain their relative positions. Then, the main winding assembly 100 is mounted on the first winding drive assembly 400, and the main cover plate 102 of the main winding assembly 100 is laterally tightened by the clamping assembly 600. The wire at the tail of the auxiliary winding assembly 200 is pulled into the main winding assembly 100, and the first winding drive assembly 400 is started in the forward direction. The first winding drive assembly 400 drives the main winding assembly 100 to rotate and wind the first layer of coil. After the first layer of coil is wound on the main winding assembly 100, as... Figure 1 As shown, the auxiliary winding assembly 200 is detached from the auxiliary fixing bracket 800 and fixed to the auxiliary wire feeding assembly 700. Then, the clamping assembly 600 on one side of the main cover plate 102 moves the main cover plate 102 laterally, clearing the position of one coil. The first winding drive assembly 400 is then activated in reverse, causing the main winding assembly 100 to rotate in the opposite direction. Using the wire in the auxiliary winding assembly 200, the second layer of coil is wound in reverse near the first layer of coil, ultimately completing the double-layer reverse coil winding. During the winding process, the wire needs to be coated with the adhesive release agent acetone; therefore, a first coating mechanism 920 and a second coating mechanism 930 are provided. After the coil winding is completed, the coil needs to be dried and shaped by the drying mechanism 940.

[0051] This invention, through the cooperation of the main winding assembly and the auxiliary winding assembly, can complete the forming of double-layer reverse coils, and the operation is stable and reliable. The main winding assembly of this invention, through the cooperation of the tensioning groove and the tensioning column, can easily realize the separation of the formed coil, thereby improving the working efficiency. The clamping assembly of this invention can adjust the distance between the main seat plate and the main cover plate, thereby adjusting the winding position.
