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.
