Description

Coil winding method and device

The present invention relates to a coil, and more particularly to a coil winding method and apparatus for winding a wire around a core portion between two flange portions of an iron core.

Generally, the coil of the wire is wound around the core portion between the flange portions of the iron core. Generally, when the wire is taken up, the wire is inserted into the flange portion as the wire end, and the wire is first fixed by spot welding on the wire. After the end flange portion, a predetermined number of winding wires are wound on the core portion, and then the other end of the wire is spot-welded and fixed to the other end of the wire end flange portion to complete the winding of the wire on the core. Generally, only a single wire is wound around the core of the core, and is usually used as an inductor. If a plurality of wires are used for positive or reverse winding, it is usually used as a transformer.

In a winding process in which a plurality of wires are simultaneously wound around a core portion of a core, a plurality of welding points are usually provided on the flange portion as the inlet end flange and the outlet end flange portion, and a plurality of hanging wires are matched. The body is used to make the turning of the wire. It is known that the wire is wound by four wires. When the four wires are wound by four hanging bodies, the wires are directly parallel to each other and are threaded into the coil. Winding, and four welding points are spot-welded on the flange portion of the inlet end to perform winding of the core portion; and when the winding is completed by the outlet end flange portion, the wire is pulled through the wire Four welding points on the outlet end flange portion, and then extending to the four hanging body around the outlet end flange portion to wrap the exit line; two of the wires wound around the two hanging wire bodies are staggered. The other two wires are wound directly in a nearly parallel manner around the wire of the two hanging wire bodies, and spot welding is performed on the four welding points on the flange portion of the outlet end.

In the prior art, the wire is wound by four wires, and the two wires are wound by two wire-wound bodies in a staggered manner, except that the wire is obliquely pulled through the flange portion of the wire end portion for welding two weldings. Outside the point, the other two welding points that extend across the two welding points and extend directly to the outer side for parallel direct welding are required, which makes the wire contact short-circuit phenomenon easily occur when the two welding points are welded. The core winding process has failed.

Accordingly, it is an object of the present invention to provide a coil winding method which can avoid the occurrence of a short circuit problem.

Another object of the present invention is to provide an apparatus for performing the coil winding method as described in claims 1 to 9.

According to the coil winding method of the present invention, a first jig is provided with a first clamping port which can be driven to rotate; the first jig is provided with a plurality of hanging wire bodies for winding the wire; The clamp is provided with a clamping seat which can be driven to rotate, and the second clamp is provided with a hanging body for winding the wire; an iron core is provided, and a plurality of welding seats at the flange portion of the inlet end are provided thereon, and a plurality of welding seats located at the outlet end flange portion, between the wire end flange portion and the outlet end flange portion for winding the core portion of the wire; the first jaw of the first clamp and the second clamp are clamped together The supporting iron core is rotated in the same rotation direction; wherein the wound core is wound by N wires, and when the winding is completed and the outgoing wire is taken, the N wires are used together to use the second clamp N/ Two hanging wire body outlets are carried out, and N welding points are spot-welded on the flange portion of the core wire outlet end, wherein N is 4.

A coil winding device according to another object of the present invention, comprising: a device for performing the coil winding method according to any one of claims 1 to 8.

The method and the device of the embodiment of the invention not only serve as a member for pushing the material at the other end of the core end into the first clamping portion of the first clamp, but also guiding the guiding member in the pre-clamping position of the core winding. The route and direction of the winding route, so that the wire which is welded after the fifth and eighth welding points is first staggered before passing through the fifth and eighth welding points, and then bypassed The first hanging line portion allows the wire to be displaced obliquely upward by the staggered upward direction but opposite to the fifth and eighth welded seats, and is rotated to the fifth and sixth hanging bodies after passing through the second hanging line portion. Winding, not only effectively deflects the wire drawing direction to avoid short circuit, but also makes N wire can only bear the hanging line of the wire end flange out line by N/2 wire hanging body, reducing the complexity of wire winding And when the jig is pushed by the front end to the iron core, it provides an appropriate distance elasticity, on the one hand, it can adapt to the iron core push distance of different specifications and sizes, on the other hand, it can provide the fixture by the top of the elastic component. When the iron core is pushed, the jig and the clamp seat can form a relative displacement in the axial direction of the iron core and the jig to obtain the exactity of the push.
