Abstract
The invention discloses a transformer coil film wrapping and sintering process, comprising the following steps of: removing an oxidation layer on the surface of a copper wire; polishing the outer wall of the copper wire; winding a polyimide wrapping belt on the surface of the copper wire; and enabling the copper wire to pass through a high-frequency spiral induction coil and heat, and controlling a difference value between an instant temperature of the copper wire and a temperature threshold to be within a certain range when the instant temperature of the copper wire reaches the preset temperature threshold. In the transformer coil film wrapping and sintering process, the film can be fully wrapped and evenly sintered and deposited on the copper wire, the adhesiveness of the film wrapping is increased, the coil is prevented from generating a cracking phenomenon when the coil is wound, thereby effectively improving the insulativity and stability of the film wire.
