Abstract

The invention discloses a surface depainting carving process for a plate with a curved surface. The surface depainting carving process mainly comprises the following steps: A, manufacturing an injection mold, and selecting suitable materials to carry out injection molding production; B, spraying paint on an injection molding product; C, manufacturing a carving fixing jig according to the product; D, manufacturing a curved surface carving document by 3D modeling, and determining a carving region; E,, fixing the product on the fixing jig and carving; and F, cleaning the surface of the plate with the curved surface, and then neatening and packing. The carving process provided by the invention is simple and convenient to operate and high in carving efficiency. Carved patterns are high in 3D third dimension, high in simulation degree and smooth in grain.

Description

technical field [0001] The invention relates to the technical field of laser engraving technology, in particular to a process for removing paint and engraving on the surface of a curved plate. Background technique [0002] With the rapid development of optoelectronic technology, the application range of laser engraving technology is becoming wider and wider, and the requirements for engraving precision are getting higher and higher. The four most fundamental factors affecting laser engraving are: engraving speed, laser power, engraving accuracy, and material. If a certain engraving effect is to be achieved on a specific material, it is required to absorb a certain energy of the laser. This energy should be regarded as the laser energy absorbed by the material = laser power / engraving speed. Simply speaking, to increase the laser energy absorbed by the material, the laser power should be increased or the engraving speed should be reduced. As for which method to use in the e...
