Description

Method and device for iron core winding wire

The present invention relates to a method and a device for winding a wire, and more particularly, to a method and a device for winding a core using a conveying device that provides an intermittently rotating conveying flow path and a plurality of workstations for core winding.

According to general inductors or transformers, copper metal wires are usually wound on metal iron cores. This type of iron core winding wire No. I500055 "coil winding method and device" patent is taken as an example. After the electrode on the first flange part of the wire entry end is welded to the electrode on the electrode of the first flange part, the wire wire is wound around a core of a roll for multiple turns, and then The electrode on the second flange part of the outlet end is pulled through, and the outlet end of the wire is welded on the electrode of the second flange part; the traditional iron core winding method uses six-degree intermittent rotation. Transporting device, and by planning six work stations equally on the intermittent rotating flow path formed around the periphery of the transporting device, six iron cores including feeding, welding, winding, welding, waste line, and collection are carried out respectively. The process of winding the wire; in order to improve the production efficiency, the conventional winding method often uses multi-axis clamps and multiple sets of needles to pull the wire in each workstation. Commonly, four or six axes are used. Come on, let every work The work station performs winding or other operations on four or six iron cores at the same time, so that each winding of the intermittent rotating flow path completes the winding of four or six iron cores. Use double winding needles for wire drawing.

In the prior art, the process of iron core winding wire is to improve the production efficiency. In a workstation, multi-axis clamps are used to wind multiple sets of needles to pull the wire. This four-axis or six-axis method is often used because multiple cores are wound at the same time. The quality of each core may be different. In the case of winding, the failure rate of the finished product tends to climb after winding; at the same time, because the wire passes through the electrode on the first flange part of a wire entry end and the wire entry end is welded on the electrode of the first flange part After the electrode, sometimes due to the uneven thickness of the tin liquid on the core's own product electrode, the wire is melted when the end of the wire is welded. When winding, the intermittent rotating flow path must be wound twice to complete the winding of the two layers on the core. In addition to the higher defect rate, even if four or six axes are used, it is delayed by one more revolution. Increased productivity.

That is, the object of the present invention is to provide a method of core winding a wire that performs two layers of wire winding on a core under an intermittent rotation stroke of a single circumference.
