Description

Technical Field

[0001] The invention relates to the technical field of glass processing, and in particular to a device and method for cutting glass external cracks with laser. Background Art

[0002] Glass cannot be cut directly after laser cutting, so other process methods are needed to break the glass (referred to as glass cracking). Currently, mechanical cracking and laser cracking process methods are commonly used. The disadvantage is that when processing multiple glasses of different sizes, the glass positioning tooling and fixtures need to be replaced. The operation and switching are cumbersome and require frequent maintenance, resulting in high equipment manufacturing and maintenance costs.

[0003] A Chinese patent document CN108529865A discloses an automobile glass cutting machine, which includes a workbench, a glass fixing assembly arranged at the bottom of the workbench, a supporting assembly arranged at the top of the workbench, a cutting assembly arranged on the supporting assembly and slidably connected to the supporting assembly, and a knocking assembly arranged at the bottom of the supporting assembly and slidably connected to the supporting assembly. The automobile glass to be processed is placed on the workbench, the glass is adsorbed and fixed by a pneumatic suction cup, the sliding block slides on the supporting assembly, and drives the second cylinder and the cutting knife to move, and the cutting knife cuts the glass. Because the cut glass will not fall off the original glass immediately, the cut glass is knocked by a knocker until the cut part falls off. The whole process is mechanical operation, which solves both the glass cutting problem and the knocking problem of the cut glass falling off.

[0004] This technical content utilizes a cutting knife to cut and uses knocking to separate the waste, which can easily cause the finished glass to break and be damaged. The method of cutting the glass to separate the waste needs to be further optimized.
