[0002] Transformer coil is a kind of coil. Transformer needs coil to operate. Coil is usually divided into two types: layer type and pancake type. The turns of coil are arranged in layers along the axial direction and wound continuously. It is called layer coil. Each layer is like a cylinder. Transformer coil winding is an important step in transformer coil production.

[0003] A Chinese patent discloses a method for winding a transformer coil (Announcement No. CN106449078A). The patented technology has the advantages of low cost and good transformer performance. However, in the above-mentioned transformer coil winding method, the grid-shaped insulating material is directly fixed by an adhesive tape, and the stability of the grid-shaped insulating material is low. The coil is easy to slip during winding, resulting in the coil being easy to short-circuit, which is not conducive to the safety of coil use. The manual placement and winding operation is completely adopted, which is not convenient for operation and is not conducive to the winding efficiency of the coil. The uniformity of the manually wound coil is low, which is not conducive to the neatness of the winding and affects the coil production quality. Therefore, a person skilled in the art provides a method for winding a transformer coil to solve the problems raised in the above-mentioned background technology. Summary of the invention
