Description

Technical Field

[0001] The utility model relates to the technical field of laser engraving, in particular to laser engraving equipment used for surface texture molding. Background Art

[0002] Laser engraving is a method of spraying a high-energy laser beam on the metal surface to vaporize the material surface and form tiny bumps or depressions. Since different materials react differently to lasers, different shapes and patterns can be formed by changing the power and focal length of the laser beam. Because the power of the laser beam is very high, the surface of the material will be damaged during processing. In order to ensure that the engraved product is qualified, assistance is required during the engraving process.

[0003] The effect of laser engraving has a high degree of three-dimensional sense, which can make patterns and text emerge on the metal surface, and the visual effect is very good. Generally, the workpiece is fixed on the workbench, and the engraving forms a preset pattern as the equipment on the workbench runs. However, in the prior art, most laser engraving workbenches carry the workpiece on the same plane. When there is a curvature on the surface of the workpiece, it will cause a certain degree of inclination in the engraving, and then engrave thick lines, which affects the aesthetics of the workpiece and reduces the qualified rate of the workpiece.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1.

The end of the screw rod 12 away from the first motor 11 penetrates into the interior of the workbench 2 and is rotatably connected thereto. The movable frame 3 is threadedly sleeved on the surface of the screw rod 12. The screw rod 12 is used to drive the movable frame 3 to move back and forth as the first motor 11 is started, so that the highest point of the engraving mold 9 is quickly moved to directly below the laser engraving mechanism 1.

[0025] Among them, two parallel sliding rods 13 are installed on the inner wall of the workbench 2, and the two sliding rods 13 are respectively located on both sides of the screw rod 12, and the sliding rod 13 is parallel to the screw rod 12.
