Description

Technical Field

[0001] The present invention relates to the technical field of inductor coil equipment, and more specifically, to an automatic winding equipment. Background Art

[0002] At present, the winding methods of inductor coils mainly include high-speed flying fork winding and center column rotation winding. Among them, high-speed flying fork winding adopts the method of rotating the winding guide needle around the center column of the coil to wind the enameled wire around the center column. This method has a fast winding speed and neat wire arrangement, but due to the limitation of the winding method, it can only wind coils with inner and outer legs. The method of center column rotation winding is to install the center column on a rotating shaft, and the winding center column actively rotates to wind the enameled wire around the center column. This method can be used to wind coils with inner and outer legs, and can also be used to wind coils with outer legs by storing wire at the starting end of the winding and then rewinding it. However, the length of the stored wire is limited, and the starting end cannot actively feed the wire. Therefore, the coil leg method can only be at one end of the coil, and the leg position cannot be selected. Summary of the invention
