Description

Technical Field

[0001] The utility model relates to the technical field of laser marking machines, and particularly relates to a laser marking machine with a positioning function. Background Art

[0002] A laser marking machine uses a laser beam to permanently mark various different material surfaces. The marking effect is achieved by evaporating the surface layer material to expose the deeper layer material, thereby engraving exquisite patterns, trademarks, and characters. Laser marking machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines, and YAG laser marking machines. However, when the existing laser marking machines mark the marked object, a program is required to cyclically operate the laser head to mark the marked object. When the marked object is offset, the marking will be offset. In view of this, we propose a laser marking machine with a positioning function. Content of the Utility Model
