China, as a large manufacturing country, with the rapid development of the national economy, the processing demand of various metal and non-metallic workpieces in industrial production is increasingly strong, and the application field of laser processing equipment has been rapidly expanded. As a "green" new technology emerging in recent years, laser processing technology is constantly trying to integrate with many other technologies in the face of the ever-changing processing needs in different fields, thus breeding new technologies and industries.
Glass can be seen everywhere in people's daily life. It can be said that glass is one of the most important materials to promote the development of contemporary human civilization and has a lasting and far-reaching impact on modern human society. It is not only widely used in construction, automobile, household goods and packaging, but also a key material in cutting-edge fields such as energy, biomedicine, information and communication, electronics, aerospace, optoelectronics, etc. It is a common processing technology to drill holes for glass, which is commonly used in various types of industrial substrates, display panels, civil glass, decoration, bathroom, photovoltaic and display covers in the electronic industry. However, high brittleness, high hardness, poor heat dissipation, large coefficient of thermal expansion, and large amount of edge collapse have become important problems puzzling glass drilling technology.
As the mainstay of the laser industry, Jinan Xintian Laser is well aware that seizing the commanding heights of disruptive technologies is the key to seizing the market. In 2022, the nanosecond green light punches and nanosecond infrared punches independently developed by Xintian have aroused unanimous praise in the industry once they are marketed. Laser glass processing has the following characteristics:
1. Fast speed, high precision, good stability, non-contact processing, and the yield rate is far higher than that of traditional processing technology;
2. The minimum diameter of glass drilling hole is 0.2mm, and square hole, round hole, step hole and other arbitrary specifications can be processed;
3. The processing method of galvanometer drilling is adopted. By using the point by point effect of a single pulse on the base material, the laser focus installation is designed to quickly scan and move on the glass, so as to remove the glass material;
4. Process from bottom to top. The laser passes through the material and focuses on the lower surface of the material. Remove the material layer by layer from the bottom. In the process of processing, the material will not appear taper, and the upper and lower apertures are consistent, realizing high-precision and efficient "digital" glass drilling.
Features of green light model:
1. The whole machine of green light products is sealed to avoid light pollution, dust pollution and other problems;
2. The edge collapse of transparent glass material processed by green light can be controlled to 100 at most μ M or so.
Infrared model features:
1. Relatively low cost;
2. Light spot is relatively soft;
3. Disadvantages are large heat and large edge collapse, generally 300 μ M or so.
