Winding device, winding method and electronic device

Abstract

The embodiment of the invention discloses a winding device, a winding method and an electronic device. The winding device comprises a die, the die comprises a main die and a bending pin, the main die comprises a base and a die core, one side of the base forms a winding space, the die core is connected with the base, and the side surface of the die core comprises a coil forming surface. The coil forming surface is configured to limit the shape of the coil; the bending pin is configured to be matched with the mold core to limit the trend of the wire rod in the coil winding process. According to the technical scheme, in the coil winding process, the two ends of the coil can be both located on the outer side of the coil, the two leading-out ends of the wound and formed coil are both located on the outer side, the coil can be conveniently connected with other circuits in the follow-up process, and meanwhile the coil can be conveniently connected with other circuits. After the coil is wound, the leading-out end of the coil does not need to be turned over by adding an additional process, so that equipment and processing processes used for processing the coil are reduced, the production efficiency is effectively improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of manufacturing wireless charging coils, in particular to a coil winding device, a winding method and electronic equipment. Background technique [0002] Wireless charging technology is more and more widely used in the field of consumer electronics. Most mobile terminal devices contain wireless charging modules, and coils, as an important part of wireless charging modules, have an important impact on charging efficiency. In the production of coils In the process, there is an increasing demand for winding technology and winding equipment. In the current winding process, in the single-layer coil winding manufacturing process, the internal incoming wire is mostly used and the external wire is discharged after winding, and a conductive interface of the wound and formed coil is set inside the coil. In the subsequent product production process, it is necessary to connect the two conductive interfaces of the coil with the ...
