Description

Technical Field

[0001] The utility model relates to the technical field of laser engraving machines, and more specifically to a positioning device for high-precision laser engraving. Background Art

[0002] Laser engraving machine, as the name suggests, is an advanced equipment that uses laser to engrave the material to be engraved.

[0003] At present, during the use of laser engraving machines, a workpiece positioning device is required for positioning. However, during use, the positioning device can only clamp the workpiece by clamping. However, when clamping a large plate-like workpiece, its clamping stability may be reduced, thereby reducing the accuracy of laser engraving. Moreover, the positioning device cannot intercept and collect the debris generated by the processing of the worktable surface.

[0004] For example, announcement No. CN218476204U discloses a positioning and dust removal device for a laser engraving machine, which includes an operating table, four supporting legs, a mounting plate and a laser engraving machine body. The four supporting legs are symmetrically fixed on the lower surface of the operating table in a group of two, and the mounting plate is fixed between the opposite sides of the two groups of supporting legs. A back plate is fixed on the upper surface of the operating table, and the laser engraving machine body is arranged on the front of the back plate.

[0005] It can be seen from the above-mentioned public scheme that the positioning mechanism can only clamp the workpiece through the clamping plate, which may cause a gap between the bottom of the workpiece and the surface of the workbench, reducing the processing accuracy. At the same time, it is impossible to intercept and collect the debris generated by processing on the surface of the operating table. The flying processing debris can only be collected by the dust removal mechanism, so that the processing debris on the surface of the operating table needs to be cleaned again, which is inconvenient.
