Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, in particular to a laser cutting device with a high-efficiency positioning function. Background Art

[0002] Limitations of traditional positioning methods: Most of the positioning devices of traditional laser cutting equipment are not accurate in positioning, have a low degree of automation, cannot automatically move objects, are inconvenient to operate, and reduce work efficiency. For example, most of the grinding and positioning devices of existing laser cutting equipment are not accurate in positioning, cannot automatically move objects, are inconvenient to operate, and require improved cutting accuracy: During the laser cutting process, if the workpiece is not firmly clamped or the positioning is inaccurate, the cutting accuracy will be reduced. For example, the cutting edge of a large-sized workpiece may produce end face burrs due to the inaccurate movement of the laser cutting machine. The end face burrs need to be ground and polished after cutting to ensure that the end face is flush. To meet the requirements of different workpieces: The thickness and shape of workpieces in industrial production vary, and the cutting device needs to be able to easily position different workpieces. For example, traditional devices are difficult to effectively clamp and fix workpieces of different thicknesses, and efficient positioning devices are required to solve this problem.

[0003] Traditional laser cutting equipment typically uses manual unloading, which is time-consuming. The laser cutting process is also very fast, leading to frequent machine starts and stops, which not only shortens the machine lifespan but also reduces processing efficiency.
