Example Embodiment

[0021] In order to describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following is a detailed description in conjunction with the embodiments and accompanying drawings.

[0022] Laser processing technology is a technology that uses the characteristics of the interaction between the laser beam and the substance to cut, weld, surface treatment, perforate, micro-process materials (including metals and non-metals), and use as a light source to identify objects. Traditional applications The largest area is laser processing technology. Laser processing systems include lasers, light guide systems, processing machine tools, control systems and inspection systems.

[0023] See figure 1 , A method of laser cutting ceramics, including:

[0024] S1. Select the part to be cut on the ceramic body;

[0025] The thickness of the ceramic body is: 0.1mm to 2.0mm.

[0026] S2. Coat the cut part with a non-volatile, non-flammable, ...

Abstract

The invention discloses a method for cutting ceramic by laser, which includes: S1, selecting portions of ceramic required to be cut; S2, coating a non-volatile non-transparent adsorption layer onto the portions to be cut; and S3, cutting along the portions to be cut by moving a laser beam. Since the adsorption layer used in the method can adsorb laser energy, cutting efficiency can be improved.

Description

technical field [0001] The invention relates to the field of laser applications, in particular to a laser cutting method for ceramics. Background technique [0002] The existing ceramic crack-free cutting method basically adopts (CO2 or Nd:YAG) laser, under the premise of constant single pulse energy, the pulse width is compressed to ns level, and the pulse frequency is increased to 10-20KHz level. Its obvious disadvantage is that it requires high equipment capacity, often requires multiple repeated cutting or pre-processing, and the practical cutting efficiency is low. With the increase of cutting speed, the slag changes from a flat shape to a directional corrugated shape; when cutting from low speed to high speed The reduction in the degree of superposition of individual pulses transforms the slag from a planar state to a discontinuous state. The cutting method is also converted from gasification and melting to fracture caused by additional partial thermal shock, and frac...
