Method and system for removing paint layer of inductance copper wire by laser

Abstract

The invention relates to the field of laser marking, and especially relates to a method and system for removing a paint layer of an inductance copper wire by a laser. The method for removing the paintlayer of the inductance copper wire by the laser comprises the following steps of fixing an inductance copper coil through a jig; calling a marking drawing file, adjusting a laser marking parameter,and carrying out rough machining on a paint layer on the surface of the inductance copper coil by adopting a green light nanosecond laser with a first characteristic; and adopting the green light nanosecond laser with a second characteristic to remove residual paint layers, wherein the first characteristic is high energy, and the second characteristic is low energy, high frequency and high speed.According to the method for removing the paint layer of the inductance copper wire by the laser provided by the invention, the erosion of insulating paint layers of the inductance copper coil can be completed only through the marking drawing file and the laser, so that the efficiency is high, the surface of the removed copper material is smooth, the damage is small, and the welding of the coil andother components is facilitated. Compared with mechanical stripping, the laser processing has high precision and high efficiency, which can reduce equipment wear and shorten the production cycle; andcompared with a chemical corrosion process, the use and discharge of chemical substances can be reduced and the pollution is less.

Description

technical field [0001] The invention belongs to the field of surface treatment and processing, and in particular relates to a method and system for removing paint layers of inductance copper coils by laser. Background technique [0002] Inductive copper coil is one of the commonly used electronic components in electronic equipment such as household appliances and instruments. Utilizing the principle of electromagnetic induction, in electronic circuits, inductive copper coils are mainly used to isolate and filter AC signals or form resonant circuits with capacitors and resistors. Inductive copper coils are also used in mobile phones that can be charged wirelessly (such as the charging coil on the Xiaomi 9 battery), which plays a key role in the realization of the wireless charging function. [0003] Inductive copper coils are usually made of enameled wires. In order to be able to weld and conduct electricity with other electronic components, it is necessary to remove the pai...
