Description

Technical Field

[0001] The utility model relates to the field of laser cutting machines, and particularly relates to a workpiece transfer device for a laser cutting machine. Background Art

[0002] A laser cutting machine emits laser from a laser, and through an optical path system, focuses it into a laser beam with a high power density. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, a high-pressure gas coaxial with the beam blows away the melted or vaporized metal. As the relative position of the beam and the workpiece moves, finally a cut is formed in the material, thus achieving the purpose of cutting.

[0003] Whether before or after cutting, the workpiece needs to be moved. Generally, the operation is that the staff places or takes away the workpiece. Firstly, it is easy to damage the workpiece. Secondly, the labor cost is high and the efficiency is low, which is not suitable for popularization. Content of the Utility Model
