Technical Field

[0002] When manufacturing coil products, especially reactor products, wire winding is required. When factors such as the wire width becoming wider and the thickness becoming narrower, or the number of wire spirals increasing, during wire winding, the arrangement of the wire in the radial direction is uneven, which in turn affects the arrangement effect in the axial direction. At the same time, it also causes an uneven result for the next layer winding base of the multi-layer wound coil product, affecting the winding quality of the coil and the appearance quality of the coil. In the prior art, generally, manual methods are used to restrain the wire, but this method is not only inefficient but also has a high labor cost. There is an urgent need for a tool to replace manual operation. Summary of the Invention

[0031] The present application will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present application.

[0032] Embodiment 1

[0033] Figure 1 , Figure 2 is a top wire wheel for winding coils in the present invention. As shown in Figure 1 , Figure 2 , a top wire wheel for winding coils in the present invention mainly includes a roller 1, a top wire wheel sleeve 2, and a top wire wheel frame 3.

[0034] The top wire wheel frame 3 includes an extension rod 301 and a roller frame 302.

[0035] The roller frame 302 is fixedly connected to one end of the extension rod 301.

[0036] The roller 1 is fixedly connected in the roller frame 302 and enables the roller 1 to rotate in the roller frame 302.

[0037] The roller 1 is used to contact the coil wire in the radial direction, control and restrain the wire in the radial direction during coil winding, and improve the flatness of the radial surface.

[0038] The top wire wheel sleeve 2 is sleeved on the extension rod 301.

[0039] The top wire wheel sleeve 2 can adjust the distance between the extension rod 301 and the coil to ensure that the roller 1 can contact the radial surface of the coil wire.

[0040] The roller 1 preferably includes at least one bearing 101.

[0041] The diameter of the roller 1 needs to match the roller frame 302; the height of the roller 1 matches the coil wire, and usually the height of the entire roller 1 is not less than the height of one turn in the wire winding direction.

[0042] The top wire wheel sleeve 2 includes an extension rod sleeve 201 and a winding arm sleeve 202.

[0043] The extension rod sleeve 201 is used to sleeved on the extension rod 301, and the extension rod sleeve 201 is configured as a structure for accommodating the extension rod 301. Preferably, a first adjustment hole for fastening the extension rod 301 is provided on the extension rod sleeve 201. The first adjustment hole is only one of the ways to fasten between the extension rod sleeve 201 and the extension rod 301. Other ways, such as external fixture control, etc., can also be realized.

[0044] The winding arm sleeve 202 is used to sleeved on the winding arm of the winding machine, and the winding arm sleeve 202 is configured as a structure for accommodating the winding arm of the winding machine. Preferably, a second adjustment hole for fastening the winding arm of the winding machine is provided on the winding arm sleeve 202. The second adjustment hole is only one of the ways to fasten between the winding arm sleeve 202 and the winding arm. Other ways, such as external fixture control, etc., can also be realized.

[0045] The length of the extension rod 301 matches the specifications of the coil and the size of the winding arm of the winding machine. Specifically, the total length of the extension rod 301 and the roller 1 is not less than the distance from the winding arm to the edge of the winding head.

[0046] Embodiment 2

[0047] This Embodiment 2 is basically the same as Embodiment 1, and the same parts will not be described here again. The difference is that the roller 1 includes at least one bearing 101 and a sleeve 102. When the height of one bearing 101 is lower than the height of one turn in the wire winding direction, multiple bearings 101 are needed to restrain the wire. However, there is a certain gap between multiple bearings 101, which will cause unevenness when restraining the wire. Therefore, a sleeve 102 is sleeved outside the bearing 101 to make the effect of restraining the wire better, and the wound coil is more beautiful and has better performance.

[0048] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0049] A top wire wheel for winding coils of the present invention has a simple structure and is convenient to operate. Fix the top wire wheel on the winding arm of the winding machine, and make the contact position between the roller of the top wire wheel and the wire more reasonable by adjusting the position; fix the top wire wheel on the winding arm to make the rising amplitude of the roller of the top wire wheel match the winding amplitude of the wire; this top wire wheel realizes the control and restraint of the radial arrangement of the wire during the winding of the inductor coil products, especially the reactor products, and at the same time cooperates with other fixtures to realize the control and restraint in both the axial and radial directions of the coil winding, improving the internal quality and appearance quality of the product.

[0050] The applicant of the present invention has made a detailed description and illustration of the embodiments of the present invention in conjunction with the accompanying drawings. However, those skilled in the art should understand that the above embodiments are only the preferred implementation schemes of the present invention, and the detailed description is only to help readers better understand the spirit of the present invention, rather than a limitation on the protection scope of the present invention. On the contrary, any improvement or modification made based on the spirit of the present invention should fall within the protection scope of the present invention.
