Laser paint stripping machine

Abstract

The invention relates to a laser paint stripping machine. The machine comprises: a solid laser light source (1); a beam expanding lens (3); two spectroscopes; eight holophotes; three galvanometer scanning systems. The each galvanometer scanning system comprises: one X-direction galvanometer, one Y-direction galvanometer and one field lens. Focal lengths of the three field lenses are the same. Laser passes through the beam expanding lens so as to be aligned and amplified, and passes through the two spectroscopes and then the eight holophotes. The laser is reflected and formed scanning beams which have mutual 120 DEG angles between each other. Three scanning beams scan simultaneously so as to form circle paint stripping around an enameled wire in space. In the invention, a speed is fast andan efficiency is high. A paint layer can be peeled thoroughly. The machine can be widely applied in a magnetic-head enameled wire, an inductance coil and surface paint stripping of a surface-varnished object whose cross section is heterotypical, such as a circle, a square, a triangle and the like.

Description

technical field [0001] The invention relates to a paint stripping machine, in particular to a laser paint stripping machine. Background technique [0002] Laser paint stripping has been widely used in the electronics industry for magnetic head coil stripping, circuit inductance coil joint stripping, and various enameled wire paint stripping. Conventional paint stripping equipment includes a laser head with a scanning galvanometer, and the entire enameled wire The device that turns the ring up and down realizes the paint stripping of the upper and lower parts of the enameled wire. However, in this method, occasionally there is the disadvantage that the joint between the upper and lower part of the paint stripping area is not clean, and the 100% pass rate cannot be guaranteed, and it is not suitable for enameled wire stripping in an assembly line, because the enameled wire in the assembly line method, along the Guide rails or conveyor belts travel in translation, which is not...

AI Technical Summary

Problems solved by technology

[0003] The problem to be solved by the present invention is: aiming at the current characteristics that the enameled wire stripping paint cannot be stripped online, the current mature galvanometer system is used to ensure high processing speed and high production efficiency, and the laser beam is divided into 3 beams of light. 3 laser scanning heads, the scanning laser beams output by these 3 scanning heads form a closed pattern with each other, which can form a 360° scan on the periphery of the enameled wire, so that the paint can be effectively stripped along the circular direction, and the online stripping of the enameled wire can be better realized paint
