Technical Field

[0001] The utility model relates to the field of plate processing, in particular to an automatic deburring device for laser-cut plates. Background Art

[0002] Laser cutting is the use of a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize or reach the ignition point, and at the same time using a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. It is one of the thermal cutting methods for cutting workpieces.

[0003] However, after laser cutting, there will be many burrs on the plate. When cleaning the burrs, the plate needs to be manually turned over, and the burrs may scratch people's hands. In addition, the current existing technology often requires the processed plate to be transferred to a special burr cleaning site for processing when dealing with burrs, which increases the workload, reduces work efficiency, and is not safe enough.
