Laser preparing method of glass black markers

Abstract

The invention discloses a laser preparing method of glass black markers. The method includes the following steps of firstly, fixing a graphite sheet to a working table, fixing a glass substrate to the upper portion of the graphite piece so that the glass substrate can make close contact with the graphite sheet; secondly, making laser beams irradiate the interface of the glass substrate and the graphite sheet, making laser beams and the working table for installing workpieces combined and linearly move in the Z direction, and conducting scanning through a galvanometer in the X / Y direction; thirdly, cleaning the glass substrate through an ultrasonic cleaning machine after marking is completed, and removing graphite residues on the surface of glass. The method has the advantages that the black markers of glass are obtained through the graphite back etching method, and the markers of high contrast can be prepared; the marking method is small in grooving heat effect and good in marking quality and has a great effect on increasing the recognition degree of the glass material markers; in addition, through the laser preparing method, the machined markers are resistant to corrosion, high temperature, water and friction and basically cause no feelings when touched by hand, and stability and durability of the markers are effectively achieved; finally, the marking method adopts the graphite sheet as the consumption material, one graphite sheet can be repeatedly used, cost is low and no pollution is caused.

Description

technical field [0001] The invention relates to the technical field of laser marking glass, in particular to a laser preparation method for glass black marking. Background technique [0002] Marking is a technique widely used in the production process. Laser marking is the process of scanning the target surface with a laser beam of appropriate energy density and converging on the surface of the workpiece, causing physical or chemical changes in the material, forming marks on the surface, and forming a mark. It belongs to a non-contact marking method. Compared with traditional processing methods (such as inkjet printing, EDM, mechanical knife engraving, etc.), it has a wide range of applications, fast marking speed, stable performance, high quality, low operating costs, low environmental pollution, easy to use computer It has the advantages of control and synchronous operation with other equipment. Therefore, laser marking has become one of the important application fields...

AI Technical Summary

Problems solved by technology

[0003] Laser marking technology can be used for marking transparent materials. In traditional laser marking of transparent materials, CO 2 The laser marks directly, but the mark directly marked by the laser on the transparent material is white or light-colored. Color marking is very necessary

Although inkjet printing can be used for colored marking on transparent materials, its marking on transparent materials is not resistant to corrosion, high temperature, and water, and its durability and stability are limited. Its cost is higher, and it also has certain pollution to the environment.
