Description

Technical Field

[0001] This utility model belongs to the field of laser drilling technology, specifically relating to a glass laser drilling machine. Background Technology

[0002] Glass materials, especially precision glass used in electronic device covers and optical components, often require high-precision drilling during processing. Laser drilling technology has become one of the mainstream glass drilling processes due to its non-contact, high efficiency, and high precision characteristics.

[0003] Key equipment for laser glass drilling typically includes a laser generating system, a positioning system for precisely moving the laser head or workpiece, and a clamping system for fixing the glass workpiece. Currently, existing technologies primarily use mechanical methods to fix glass workpieces. For example, the utility model patent CN218426295U, "A Glass Laser Drilling Machine," uses clamping components to physically hold and position the glass edges. This mechanical fixing method may cause stress concentration at the glass edges. For ultra-thin, high-hardness, or large-sized glass workpieces, this localized stress can easily lead to micro-cracks or even breakage, directly affecting product yield. Furthermore, mechanical clamping requires more complex positioning, clamping, and releasing actions, making it difficult to achieve efficient continuous production. It also has low adaptability to irregularly shaped or different-sized glass. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a glass laser drilling machine with a simple structure and convenient use. It can adapt to the processing of glass of various shapes and sizes, which is conducive to improving product yield and production efficiency.

The optical path outlet of the laser marking component is vertically downward and directly faces the vacuum adsorption component set on top of the Z-axis linear module. The vacuum adsorption component includes a vacuum platform, which is connected to the top of the Z-axis linear module. The top surface of the vacuum platform is a flat adsorption surface with several adsorption micropores.
