Description

TECHNICAL FIELD

[0001] The utility model relates to glass substrate cutting technology especially relates to laser cutting glass substrate hole digging crack detection equipment. BACKGROUND

[0002] In today's digital age, the market demand for electronic consumer goods is growing explosively, and glass, as a key material, has been widely used in various electronic products. From smartphones, tablets to smartwatches, glass not only provides an attractive appearance for the product, but also bears important functions such as protecting internal components and enabling touch interaction. With consumers' pursuit of thin and high-performance electronic products, the precision and quality requirements for glass processing are becoming increasingly stringent. In particular, the demand for hole digging on glass is increasing, such as reserving mounting hole positions for cameras, sensors, etc. However, traditional processing methods, such as CNC engraving, face the dilemma of a significant decline in yield and efficiency when processing thin glass hole digging. Therefore, glass laser cutting hole digging technology has emerged, which can instantly vaporize glass with its high peak power and high energy density, and can achieve precise hole digging with precise motion control, with many advantages such as small taper, high precision, and small edge collapse, and is easy to integrate into automated production processes, becoming a research hotspot in the field of glass processing. Under this background, the development of laser cutting glass substrate hole digging crack detection equipment is crucial to ensure the quality of glass processing and improve production efficiency.

[0003] Currently, for the detection of laser cutting glass substrate hole digging cracks, the existing technology mainly uses some basic mechanical structures and detection principles. In the overall architecture of the detection equipment, a simple metal platform is usually used as a support base to place the glass substrate to be detected. In terms of cutting precision detection, optical imaging systems are often used, such as using a common industrial camera with a fixed focal length lens to capture images of the cutting hole on the glass substrate, and then using simple image measurement software on the computer display to manually select several points on the cutting hole edge to approximate the cutting precision by calculating the distance between the points. This method relies on manual operation and is highly subjective, and for complex-shaped cutting holes, the measurement error is large. For crack detection, it is usually observed by artificial visual observation of the glass surface with the help of a simple tool such as a magnifying glass to determine whether there are cracks, edge collapse and other defects. In terms of detection process, cutting precision detection and crack detection are usually carried out separately, and there is a lack of effective data correlation and integration between different detection links, making it difficult to comprehensively and systematically evaluate the processing quality of the glass substrate.
