Description

Technical Field

[0001] The invention relates to the technical field of laser cutting assistance, in particular to an auxiliary device for a laser cutting machine. Background Art

[0002] Laser cutting machine is to focus the laser light emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. As the relative position of the beam and the workpiece moves, the material is eventually cut, thus achieving the purpose of cutting.

[0003] When an existing laser cutting machine is in use, the metal will produce plasma smoke under the high temperature of the laser. After long-term use, the plasma smoke becomes granular and easily adheres to the light output head of the focusing laser head of the laser cutting machine, affecting the adjustment of the laser defocus amount and causing the cutting quality to deteriorate. Therefore, in order to ensure normal cutting, the lens surface must be kept clean.

[0004] In the prior art, when cleaning the lens, the machine is generally shut down first, and then the lens is cleaned or replaced. However, the shutdown prolongs the processing time and reduces the work efficiency. When positioning structures such as plates, the positioning effect is poor, which affects the subsequent laser cutting. Therefore, it does not meet the existing needs. We propose a laser cutting machine auxiliary device. Summary of the invention
