An assembly method of a wireless charging receiving coil module

Abstract

The invention provides a method for assembling a wireless charging receiving coil module, which relates to the technical field of wireless charging, including: using laser equipment to remove the self-adhesive layer and insulating layer on the surface of the inner outgoing line and the outer outgoing line respectively; intercepting enameled wires with special-shaped cross-sections to obtain The first enameled wire with a special-shaped cross-section having the length of the first preset specification, and removing the self-adhesive layer and insulating layer at both ends of the enameled wire with a special-shaped cross-section; melting and connecting one end of the enameled wire with a special-shaped cross-section and the inner outgoing wire of the receiving coil through a pressure welding process , the other end protrudes from the bottom of the receiving coil to the outer layer of the receiving coil; attach the bottom of the receiving coil to the multi-layer magnetic material, and fix the outer wire and the first enameled wire with special-shaped cross-section extending to the outer layer of the receiving coil processing to form a wireless charging receiving coil module. The thickness of the assembly is effectively reduced, reducing the possibility of causing problems such as reduced charging efficiency and heating of electronic equipment; the assembly process is simplified and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a method for assembling a wireless charging receiving coil module.

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.
