Description

Technical Field

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

[0002] Laser cutting machines have significant advantages when cutting metal signs. First, laser cutting machines can achieve high-precision cutting with an accuracy of up to millimeter level, ensuring that the edges of the signs are smooth and accurate. Secondly, laser cutting is fast and efficient, and can quickly complete the cutting of a large number of signs, improving production efficiency. In addition, laser cutting is a non-contact processing, with no external force squeezing the material, a small heat-affected zone, and reduced material deformation and damage. Finally, laser cutting machines are easy to operate. You only need to import the graphics into the computer to achieve automatic cutting, saving labor costs.

[0003] In the process of implementing the solution, the inventors found that the following problems in the prior art have not been well solved: laser cutting will generate a large amount of debris. In order to prevent the debris from accumulating on the workbench of the laser cutting machine, the workbench is set to a hollow shape, containing multiple serrated brackets inside, and a grid is placed on the bracket. The mesh holes of the grid are embedded in the tooth grooves, thereby providing a placement platform for the metal sign. However, since the surface of the grid is not a pure plane, the metal sign will be slightly tilted when placed on it, and the laser cutting light beam is vertical, so due to the low horizontal accuracy, the metal sign will have cutting defects when being laser cut.

[0014] 1. The rotation of the extrusion screw pushes the top plate upward, so that the pneumatic suction cup can limit the bottom corners of the metal sign. It not only achieves the effect of adsorption and limitation on the corners of the metal sign, so that it maintains stability when being laser cut, but also can fine-tune the height of the corners.
