As a major manufacturing country, China's rapid economic development has led to an increasing demand for the processing of various metal and non-metal workpieces in industrial production and the rapid expansion of the application areas of laser processing equipment. As a new "green" technology that has emerged in recent years, laser processing technology is constantly trying to integrate with many other technologies to create new technologies and industries in the face of the ever-changing processing needs of different fields.
Glass is found everywhere in people's daily lives and is arguably one of the most important materials contributing to the development of contemporary human civilisation, with a lasting and far-reaching impact on modern human society. It is not only used in a wide range of applications in construction, automobiles, housewares and packaging, but is also a key material in cutting-edge fields such as energy, biomedicine, information and communications, electronics, aerospace and optoelectronics. Drilling of glass is a common process and is commonly used in various types of industrial substrates, display panels, civil glass, decoration, bathroom, photovoltaic and display covers for the electronics industry. However, high brittleness, high hardness, poor heat dissipation, high coefficient of thermal expansion and high chipping have become important problems that plague glass drilling technology.
Laser glass processing has the following characteristics.
1. fast speed, high precision, good stability, non-contact processing, the yield rate is much higher than the traditional processing process.
2. the minimum diameter of the glass drilling hole is 0.2mm, and any size of square, round and step holes can be processed.
3. using the vibration mirror drilling processing method, using a single pulse on the substrate material point by point action, the laser focus installed predesigned path on the glass rapid scanning movement, to achieve the removal of glass materials.
4. Bottom-to-top processing, where the laser passes through the material to focus on the lower surface of the material, starting from the bottom and removing the material layer by layer upwards. There is no taper in the material during the process and the top and bottom holes are of the same diameter, resulting in highly accurate and efficient "digital" glass drilling.
