As shown in fig. 2, in the present embodiment, the winding mold assembly 22 includes a positioning seat 221, and a discharging plate 222, a profile plate 223, and a guiding plate 224 stacked in sequence. The positioning seat 221 is connected to the second slide rail 25, and the discharging plate 222, the profile plate 223 and the guiding plate 224 are all located in the placing space of the positioning seat 221. The placing space of the positioning seat 221 is a rectangular space, so that the discharging plate 222 can be conveniently supported after the winding of the required coil 100 is completed, and therefore, one corner of the positioning seat 221 is designed to be in an open form so as to conveniently support the discharging plate 222. The discharging plate 222, the profile plate 223 and the guiding plate 224 are all rectangular plates, positioning pins are inserted into the positioning through holes at four corners for positioning and stacking, and insertion holes are correspondingly formed in the other three corners of the positioning seat 221 for inserting the positioning pins into the insertion holes for positioning.

In this embodiment, the anti-rebounding sheet 225 is made of a material having elastic deformation capability, such as a silicon rubber plate, a rubber plate, or a silicon rubber composite material, so that after the wire 120 is extruded through the anti-rebounding through slot 2250, the rebounding force of the wire 120 itself cannot overcome the elastic force of the anti-rebounding sheet 225 to block rebounding.

Specifically, the guide shaft 233 is sleeved with a bearing 2330 which rotates around the axis of the guide shaft 233, and the outer wall of the bearing 2330 is in contact with the groove wall of the guide through groove 2240 and the groove wall of the bulletproof through groove 2250. In the process of winding the required winding coil 100, a worker rotates the winding mold assembly 22 to perform winding, and at the moment, the bearing 2330 rotates along the groove wall of the guide through groove 2240 and the groove wall of the bulletproof through groove 2250, so that the friction force borne by the guide shaft 233 is reduced, and the winding motion is smoother.

The winding device of the present embodiment is applied to coil winding, and first, the thread material 120 is pulled out from the bobbin 123, so that the thread material 120 passes through the guiding member 23, and then extends out from the end of the guiding shaft 233, and the head of the thread material 120 is placed at the initial position of the desired winding coil 100 in the middle of the former plate 223, the thread end is fixed by the thread pressing block (the thread pressing block can be connected to the former plate 223 by a screw), and then the winding mold assembly 22 is rotated, and the end of the guiding shaft 233 presses the thread material into the through groove 2230 of the mold, and the position change of the winding process is completed by the rotation of the first slide rail 24, the second slide rail 25, and the winding mold assembly 22 itself.

After the different winding die assemblies are replaced, since the thickness sizes of the plates are different, the thickness change of the winding die assembly 22 is adapted through the elastic deformation of the compression and extension of the coil spring 235 sleeved on the guide shaft 233, so that the winding coil processing device can have wider adaptability to the different winding die assemblies.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
