Abstract

The invention belongs to the field of alloy wire preparation, and particularly discloses a preparation method of an alloy wire for wireless charging and a multi-target magnetron sputtering device forpreparation. The alloy wire is formed by iron and copper, the mass percent of the iron ranges from 20 wt% to 40 wt%, and the copper coats the outer surface of a copper wire. The pure iron layer on theouter portion of the alloy wire has good magnetic permeability, the magnetic coupling efficiency of a receiving coil can be improved, and therefore the wireless charging power and efficiency are improved. The preparation method of the alloy wire comprises the steps that firstly, the copper wire of the proper size is selected; then, alloy wire base metal is prepared and obtained through the multi-target magnetron sputtering device; the surface of the copper wire is plated with iron in a multi-target magnetron sputtering manner, and the thickness of pure iron on the surface of the wire is guaranteed; and finally, drawing is carried out, the alloy wire base metal is drawn, and a finished product of the alloy wire for wireless charging is prepared. According to the preparation method of the alloy wire, preparation is convenient, pollution is low, the pure iron plating layer of the alloy wire is uniform, and great significance is achieved in development of the wire for wireless charging.

Description

technical field [0001] The invention belongs to the field of alloy wire preparation, and in particular relates to a method for preparing an alloy wire for wireless charging and a multi-target magnetron sputtering device for the preparation. Background technique [0002] With the development of wireless charging technology, more and more electronic products have realized the wireless charging function. At present, wireless charging is mostly realized by electromagnetic induction coupling. The principle of electromagnetic induction coupling is that the magnetic fields generated by the transmitting coil and the receiving coil interact The coupling between them realizes wireless charging, but the current wireless charging power is small and the charging time is long, which cannot meet the high-power and high-efficiency wireless charging requirements of electronic products. [0003] In the existing electromagnetic induction coupling wireless charging equipment, the coils at the t...
