Description

Technical Field

[0001] The utility model relates to the technical field of laser marking machines, in particular to a laser marking machine provided with a protective structure. Background Art

[0002] Laser marking machine uses laser beam to mark permanently on the surface of various materials. The effect of marking is to expose deep materials through evaporation of surface materials, thereby engraving exquisite patterns, trademarks and texts. Laser marking machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines and YAG laser marking machines. Laser marking machines are mainly used in some occasions that require finer precision and higher accuracy. After retrieval, the relevant document (CN219443846U) discloses a protective device for a laser marking machine, including a fixed protective cover, a side protective door and a drive assembly. The rear bottom of the fixed protective cover is fixed to the upper side of the workbench, and the lower part of the two side facades of the fixed protective cover perpendicular to the feeding direction is provided with a feeding opening, the driving assembly is fixed to the outside of the feeding opening, the side protective door is connected with the driving assembly, and an observation window is provided on the front side of the fixed protective cover. The marking head is protected by a fixed protective cover. When feeding, the side protective door is moved away by the driving component to facilitate feeding. After feeding is completed, the side protective door is closed, which can effectively protect the target position and reduce safety hazards. At the same time, it can effectively prevent the debris generated during marking from splashing. The device has a simple structure, is easy and quick to use, and can effectively improve the safety of the laser marking machine operation.

[0003] However, the above structure still has some shortcomings. It can only prevent objects from splashing when the marking machine is working, but cannot handle the smoke and flying debris generated during the marking operation. Since the smoke generated during marking is produced by the marking machine using laser to engrave other materials, harmful substances may exist. Operators work under smoke for a long time, and the safety is poor. Utility Model Content
