[0001] The utility model relates to the technical field of laser marking machines, in particular to a fixture for a laser marking machine. Background Technique

[0002] Laser marking machines mainly use different lasers to irradiate the laser beam onto the surfaces of various materials, and through the light energy, physical or chemical changes are made to the surface materials, so as to engrave patterns, trademarks and characters. They are widely used in industrial production, especially in fields such as electronic products, jewelry, auto parts, medical devices, plastic products, packaging industries, etc. When using laser marking, fixtures are required to fix and position workpieces to ensure that the workpieces can be stably maintained at a specific position during the marking process. The existing fixtures for laser marking machines usually use fixed clamps to fix materials for marking work. Due to the different thicknesses and marking angles of the marking materials, the use of fixed clamps requires frequent adjustment, which increases the operation time. And after frequent adjustment, it is easy to make the marking position of the material inaccurate or the material damaged, resulting in unclear marks or non-compliance with requirements, affecting the marking quality. Therefore, we propose a fixture for a laser marking machine to solve the problems raised above. Content of the Utility Model
