Laser marking machine and laser engraving method thereof

Abstract

The invention relates to the technical field of laser engraving, in particular to a laser marking machine and a laser engraving method thereof. The laser marking machine comprises a host machine and a laser head arranged in front end of the host machine, wherein the host machine is arranged at rack, and a support frame is correspondingly arranged under the laser head. A water disc is arranged on the support frame, a feed cock is arranged on the water disc, and a water outlet is arranged at the bottom of the water disc. Meanwhile, the invention also discloses the laser engraving method using the laser marking machine. The laser marking machine has a simple structure and is convenient to operate. The laser engraving method has the advantages of simple process and strong operability, the production efficiency is greatly increased, and the cost is saved.

Description

Technical field [0001] The invention relates to the technical field of laser engraving, in particular to a laser marking machine and a laser engraving method. Background technique [0002] The laser marking machine is a common equipment used for laser engraving on plastic products as an identification mark, and it is well known. The laser marking machine emits a laser beam and irradiates the plastic product. The surface of the plastic product absorbs the laser energy and generates a thermal excitation process in the irradiated area, so that the surface temperature of the plastic product rises to produce melting, candle burning, evaporation, and scratches, which appear at first The words set in the host of the laser marking machine. The existing laser marking machine produces the scratched words on the surface of plastic products. The color is the same as that of the plastic product. There are defects and shortcomings of unclear words. To solve this technical problem, the existin...

AI Technical Summary

Problems solved by technology

The scratched words produced by the existing laser marking machine on the surface of plastic products have the same color as the plastic products, and there are defects and deficiencies in which the words are not clear. In order to solve this technical problem, the existing method is to paint on the scratched words. A layer of paint of other colors, and then wipe off the paint around the characters, the operation is troublesome, time-consuming and labor-intensive, and it is easy to fall off
