Therefore, the winding is an important part of the transformer. The winding is made of copper wire, and the copper wire needs to be shaped using a wire mold during the winding process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figures 1-4, in order to solve the problem that the traditional device cannot adjust the winding coil diameter, the following technical solution is provided. By adjusting the mechanism, the position of the winding roller 2 is changed to adjust the winding coil diameter according to different situations. Specifically, it is disclosed that: an installation disk 1 is installed between the winding machine, and a winding roller 2 is installed between the left and right installation disks 1. A limiting sliding groove 3 is penetrated and opened inside the installation disk 1, and the winding roller 2 and the limiting sliding groove 3 form a sliding structure. An adjusting mechanism for adjusting its position to change the winding coil diameter is arranged inside the winding roller 2. The adjusting mechanism includes a support rod 4 fixedly installed on the inner surface of the installation disk 1, and a sliding sleeve 5 is penetrated and slidably installed outside the support rod 4. A telescopic cylinder 6 for driving the sliding sleeve 5 to move is fixedly installed between the sliding sleeve 5 and the side surface of the installation disk 1, and a push rod 7 is rotatably installed between the sliding sleeve 5 and the winding roller 2.

[0031] When using the device, first install the installation disk 1 in the winding machine, and then the winding machine drives the installation disk 1 to rotate. The copper wire is wound by the winding roller 2 inside the installation disk 1 to finally form the winding of the transformer (two independent coils are respectively wound outside the first roller body 201 and the second roller body 202, thereby improving the overall winding efficiency). When producing transformer windings of different sizes, first turn on the telescopic cylinder 6, and use the telescopic cylinder 6 to drive the sliding sleeve 5 to slide correspondingly outside the support rod 4. During the movement of the sliding sleeve 5, the push rod 7 is driven to rotate, and finally the push rod 7 drives the winding roller 2 to change its position (at this time, the winding roller 2 slides correspondingly in the limiting sliding groove 3 opened in the installation disk 1), so as to wind windings with different coil diameters.

[0032] Embodiment Two: Please refer to Figure 5 , in order to solve the problem that the traditional device is not convenient to remove the wound coil, the following technical solution is provided. After the winding is completed, the winding roller 2 is disassembled to achieve the purpose of convenient removal. Specifically, it is disclosed that: the winding roller 2 is divided into two parts, a first roller body 201 and a second roller body 202. A disassembly and installation mechanism for facilitating demoulding is arranged between the first roller body 201 and the second roller body 202. A docking block 8 is fixedly installed at the top of the second roller body 202, and the docking block 8 and a docking groove 9 opened at the top of the first roller body 201 are inserted and engaged with each other. The cross-sections of the docking block 8 and the docking groove 9 are both set as square structures, and a fixing bolt 10 for fixing the docking block 8 is installed inside the first roller body 201 in a threaded manner.

[0033] After the winding is completed, take out the fixing bolt 10, loosen the fixation between the fixing bolt 10 and the docking block 8, and then pull out the docking block 8 from the docking groove 9 to realize the separation between the first roller body 201 and the second roller body 202. After the separation is completed, the wound coil can be removed.

[0034] Embodiment Three: Please refer to Figure 6 and Figure 7, in order to solve the problem that the end of the coil becomes loose when the traditional device is in use, the following technical solution is provided. After the winding is completed, the winding roller 2 is disassembled to achieve the purpose of convenient removal. Specifically, it is disclosed that a limiting mechanism for fixing the end of the wire harness is arranged outside the mounting plate 1. The limiting mechanism includes a connecting plate 11 rotatably mounted on the outer surface of the mounting plate 1. The front end of the connecting plate 11 is provided with a limiting plate 13 in an arc structure, and an adsorption magnet 12 for adsorbing the mounting plate 1 is fixedly mounted on the outer surface of the rear end of the connecting plate 11. A connecting rod 14 is fixedly mounted on the upper surface of the connecting plate 11, and a through-type sliding structure is formed between the connecting rod 14 and the connecting plate 11. Moreover, a compression spring 15 is installed outside the lower end of the connecting rod 14.

[0035] When the winding is completed, the connecting plate 11 outside the mounting plate 1 is rotated inward (after the rotation is completed, the connecting plate 11 is fixed by the magnetic adsorption between the adsorption magnet 12 and the mounting plate 1). After the rotation, the limiting plate 13 is located outside the winding roller 2. At this time, under the elastic pushing action of the compression spring 15, the connecting rod 14 drives the limiting plate 13 to move downward, so as to fix the end of the wound copper wire by using the limiting plate 13 and avoid the situation of loosening.
