Assembling method of wireless charging receiving coil module

Abstract

The invention provides an assembling method of a wireless charging receiving coil module, and relates to the technical field of wireless charging. The assembling method comprises the following steps:removing self-adhesive layers and insulating layers on the surfaces of an inner outgoing line and an outer outgoing line by adopting laser equipment; intercepting a special-shaped section enameled wire to obtain a first special-shaped section enameled wire with a first preset specification length, and removing self-adhesive layers and insulating layers at the two ends of the first special-shaped section enameled wire; making one end of the first special-shaped section enameled wire in fusion connection with the inner outgoing line of a receiving coil through a pressure welding process, and extending the other end out of the outer layer of the receiving coil from the bottom of the receiving coil; and attaching the bottom of the receiving coil to a multi-layer magnetic material, and fixing the outer outgoing line and the end, extending out of the outer layer of the receiving coil, of the first special-shaped section enameled wire to form a wireless charging receiving coil module. The assembly thickness is reduced, and the possibility of problems causing charging efficiency reduction, electronic equipment heating and the like is reduced. The assembly process is simplified, and the manufacturing cost is reduced.

Description

AI Technical Summary

Problems solved by technology

At present, the total thickness of the wireless charging receiver module depends on the thickness of the assembly assembly of magnetic materials, coils and connecting wires. It is usually assembled by connecting the lead wires at the end of the inner ring of the coil to the lead wires at the end of the outer ring of the coil. The thickness of the connecting wire and the coil body will be superimposed, resulting in an increase in local thickness. In addition, the excessively thick connecting wire needs to open a window or slot on the magnetic isolation sheet, which will cause magnetic flux leakage, resulting in a decrease in charging efficiency and heating of electronic equipment. disadvantages

There are many manufacturing processes in this way, and it also makes the assembly process more complicated, and the equipment cost in the early stage is relatively expensive.
