Description

Technical Field

[0001] The utility model relates to the technical field of laser engraving machines, in particular to a high-precision laser engraving machine. Background Art

[0002] Laser engraving machines use laser beams to permanently mark the surfaces of various materials. The marking effect is achieved by evaporating the surface material to reveal the underlying material, or by causing chemical and physical changes in the surface material through light energy, or by burning away part of the material through light energy, revealing the desired pattern or text.

[0003] For example, a laser engraving machine workbench structure with application number CN221494714U includes a workbench surface, a work plate provided on the surface of the workbench surface, a first side plate provided on the side of the workbench surface, a second side plate provided on the side of the workbench surface, a first threaded rod passing through the interior of the first and second side plates, a first turntable welded to one end of the first threaded rod, a first fastening plate fixedly connected to one end of the first threaded rod, and a sliding block embedded in the interior of the first fastening plate. This laser engraving machine workbench structure is achieved by adding a first side plate and a second side plate to the side of the workbench surface, and installing a first threaded rod inside the first and second side plates, adding a first fastening plate at one end of the first threaded rod, and installing a fastening plate at one end of the sliding block. When an object needs to be engraved, it only needs to be placed on the workbench surface, and when the first turntable is rotated, the second fastening plate can clamp the object from all four sides, making the engraved object more stable.

[0004] The above patent proposes that the fastening plates can be used to clamp the objects from all sides. However, when the number of processed objects is too large, the turntable is rotated to drive the fastening plates to clamp or release the processed objects. Such repeated operations will affect the processing speed of the objects and are inconvenient to use.

[0005] So we proposed a high-precision laser engraving machine to solve the above problems. Utility Model Content
