Laser scribing glass processing method

Abstract

The present invention relates to the technical field of laser glass processing, and discloses a laser scribing glass processing method. The method is as follows: first selecting a suitable laser beam, washing to-be-treated workpieces glass for decontamination, placing the to-be-treated workpieces glass horizontally on a three-dimensional mobile platform, adjusting the Z axis height of the three-dimensional mobile platform to allow a focal position of the laser beam to be in a set range on the lower surface of the to-be-treated workpieces glass; using the laser beam for scribing processing of the to-be-treated workpieces glass in accordance with a set pattern and path, forming a cutting groove body on the bottom of the to-be-treated workpieces glass, and reciprocating the Z-axis of the three-dimensional mobile platform to complete the scribing processing process of the to-be-treated workpieces glass; and finally, cleaning and testing the finished workpiece glass. The method can meet the high precision and low damage glass cutting requirements, the processing method is simple in the process, and needs no subsequent additional auxiliary machinery operation, and in the case of no addition of cost, the laser glass processing can be realized by addition of a laser.

Description

technical field [0001] The present invention relates to the technical field of laser glass processing, and more specifically relates to a method for cutting glass by using laser marking, which can realize various graphics (not just straight lines) and thickness cutting. Background technique [0002] Glass, an amorphous solid with irregular structure, forms a continuous network structure when molten, gradually increases in viscosity and hardens during cooling, has no fixed melting point, and its main component is silicon dioxide, with a wide variety, accompanied by doping substances The different forms and characteristics of glass are different. With the development of science and technology, glass has been widely used in all aspects of life, including construction, chemical industry, military, household life industrial design, etc., and ceramic materials and organic polymer materials. Composed of three pillars of non-metallic materials. [0003] With the popularization of g...

Problems solved by technology

[0006] Today's research on laser glass processing mainly focuses on the cutting and processing of glass under the combined action of laser-induced and external mechanical stress, especially carbon dioxide laser. The principle is that the focused carbon dioxide laser beam acts on the glass surface, and the glass absorbs The beam energy generates heat accumulation, and at the same time assists quenching or cooling gas acts on the laser scanning path. When the sharp temperature difference changes, cracks are generated inside the glass along the cutting direction, and the subsequent mechanical processing is used for cracking operations. This process has the advantages of A certain application market, but due to the single cutting pattern, it has great limitations
