Method and system for laser removing paint layer of inductance copper coil

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 present invention belongs to the field of surface treatment processing, and more particularly to a method and system for laser removal inductive copper coil paint layers. Background technique [0002] The inductor copper coil is one of the common electronic components of electronic devices such as household appliances, instrumentation. With the principle of electromagnetic induction, in the electronic circuit, the inductive copper coil is mainly to isolate, filter, or constitute a resonant circuit such as a capacitor, a resistor or the like. The inductive copper coil is also used in a wirelessly chargeable mobile phone (such as the charging coil on the millet 9 battery), the implementation of the wireless charging function plays a key role. [0003] The inductive copper coil is usually wound by the enameled wire, in order to be soldered and electrically conductive with other electronic components, it is necessary to remove the lacquer layer at the weldi...
