A kind of ultra-thin coil tooling fixture, preparation method and preparation equipment

Abstract

The invention discloses an ultra-thin coil tooling fixture, a preparation method and a preparation device. The ultra-thin coil tooling fixture includes a locking piece, a cover plate, a mold core, a mold cover, a bottom plate, and a heat-conducting piece; one end of the locking piece The mold core is detachably connected through the cover plate, and the mold sleeve is set on the mold core. The peripheral side of the mold sleeve is provided with a top screw for locking and unlocking the position between the mold sleeve and the mold core. The bottom plate and the mold sleeve are far away from the cover plate. One side is fixedly connected, and the mold core is connected to an external heat source through a heat conduction member; wherein, in the coil winding state, the mold sleeve cooperates with the mold core through a top wire to adjust and lock the distance between the cover plate and the mold sleeve. Among them, the cover The distance between the plate and the mold sleeve is the width of the coil winding, and the mold core is the central axis of the coil winding; when the coil is pressed, the top wire is in an unlocked state, and the cover plate and / or bottom plate are pressure plates for The wound coil is pressed. The invention has the technical characteristics of high production efficiency, small thickness of prepared coils, strong versatility, good heat dissipation performance and low cost.

Description

technical field [0001] The invention belongs to the technical field of coil preparation, and in particular relates to an ultra-thin coil tooling fixture, a preparation method and a preparation device. Background technique [0002] With the increasing popularity of smart devices in the market, the charging technology of smart devices has also been continuously developed. Among them, wireless charging has gradually become one of the important charging methods for smart devices. In the field of wireless charging technology, electromagnetic induction wireless charging is a principle of using transformer coupling to couple the coil in the receiver and the coil in the transmitter to realize the function of charging the power supply equipment, and the coil is to realize this kind of One of the core hardware of wireless charging technology. [0003] At present, the production process of wireless charging coil products adopts winding type and FPC to produce and produce: [0004] Fo...

AI Technical Summary

Problems solved by technology

[0004] For the implementation of FPC, firstly, the cost of its preparation equipment is high, and secondly, it needs to go through multiple processes such as drilling, copper plating, etching, and covering film, resulting in a high overall defect rate. There are still some bottlenecks in the double-layer thickness process, and the relative manufacturing cost is still relatively high compared with the winding process;

[0005] For the realization of winding, firstly, the production efficiency of the coil is low, and secondly, one tooling jig usually corresponds to one coil product. If multiple coil products need to be produced and processed, multiple sets of coil jigs need to be prepared, which causes Unnecessary waste of cost, and the jig processing cycle is long, and the debugging operation is cumbersome, especially when facing the instability of the coil size and shape of the new project, too many unwinding tooling jigs will increase the cost risk of the project itself, product yield risk;
