Technical Field

[0001] This utility model relates to the field of laser marking machine technology, and in particular to a multi-head laser marking machine. Background Technology

[0002] Laser marking machines use a laser beam to create permanent marks on the surfaces of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, thus creating exquisite patterns, trademarks, and text.

[0003] For example, CN221817640U discloses a multi-head laser marking machine, including a conveying device and a laser marking assembly. The conveying device includes a dual-channel conveying mechanism with a central plate extending forward and backward. Conveying units for conveying incoming materials are provided on both the left and right sides of the central plate. The laser marking assembly is correspondingly arranged with the dual-channel conveying mechanism and includes two laser marking units.

[0004] In the existing technology, laser marking machines are used to mark different workpieces. However, some workpieces are irregularly shaped and easily move on the worktable, which may cause the laser beam to be accidentally focused on an unexpected position on the workpiece, resulting in local overheating, scorching or deformation of the workpiece. Utility Model Content
