Ultrathin coil tool jig, preparation method and preparation equipment thereof

Abstract

The invention discloses an ultra-thin coil tool jig, a preparation method and preparation equipment thereof. The ultra-thin coil tool jig comprises a locking piece, a cover plate, a mold core, a moldsleeve, a bottom plate and a heat conduction piece. One end of the locking piece penetrates through the cover plate to be detachably connected with the mold core, the mold core is sleeved with the mold sleeve, jackscrews used for locking and unlocking the position between the mold sleeve and the mold core are arranged on the peripheral side of the mold sleeve, the bottom plate is fixedly connectedwith the side, away from the cover plate, of the mold sleeve, and the mold core is connected with an external heat source through the heat conduction piece. In the coil winding state, the mold sleeveis matched with the mold core through the jackscrew and used for adjusting and locking the distance between the cover plate and the mold sleeve, the distance between the cover plate and the mold sleeve is the winding breadth of the coil, and the mold core is a winding center shaft of the coil; and in a coil pressing state, the jackscrew is in an unlocked state, and the cover plate and/or the bottom plate are/is a pressing plate used for pressing the wound coil. The method has the technical characteristic of high production efficiency, and the prepared coil has the advantages of small thickness, strong universality, good heat dissipation performance, low cost and the like.

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;
