Abstract

The invention belongs to the field of alloy wire preparation, and specifically discloses a preparation method of alloy wire for wireless charging and a multi-target magnetron sputtering device for preparation. The alloy wire is composed of iron and copper, and the mass percentage of iron is 20-40wt%. Iron clads the outer surface of the copper wire. The outer pure iron layer of the alloy wire has good magnetic permeability, which can improve the magnetic coupling efficiency of the receiving coil, thereby improving the power and efficiency of wireless charging. The preparation method of the alloy wire includes: firstly, selecting a copper wire of a suitable size; secondly, preparing the base material of the alloy wire through a multi-target magnetron sputtering device; The thickness of pure iron on the surface of the wire. Finally, drawing is carried out, and the base material of the alloy wire is drawn, and finally a finished product of the alloy wire for wireless charging is obtained. The preparation method of the alloy wire provided by the invention has the advantages of convenient manufacture, less pollution, uniform pure iron coating of the alloy wire, and is of great significance to the development of wire materials 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...
