Problems solved by technology

However, in the traditional processing method, the laser directly acts on the surface of the material. Because the laser spot is large (about 0.2-1.0mm), and the spot will produce a certain heat-affected zone when the thin film is ablated, the existence of the heat-affected zone wi

Embodiment Construction

[0012] Referring to FIGS. 1-2 , the method of this embodiment includes the following equipment: a laser galvanometer marking device 1 , a metal template 2 , a workbench 3 , an electromagnet adsorption device 5 and a workpiece adsorption device 6 .

[0013] The main body is the laser galvanometer marking device 1. The galvanometer marking is a conventional and mature technology in laser applications, and can work stably for a long time. The description is omitted here. The metal template 2 is the core of the present invention. The iron template is made by etching or ablation patterns and textures according to the needs, and the places that need to be printed, marked and etched are hollowed out on the template. During processing, the template is set or placed on the workpiece 4---the veneer, and the laser emitted by the laser galvanometer marking device scans the entire area, and the laser carbonizes or burns the surface of the sheet at the hollowed out part of the metal template...

Abstract

A method for machining on non-metal sheet by laser includes such steps as preparing a metallic mask with carved pattern, putting the metallic mask on the non-metal sheet to be machined, and using laser beam to scan on the mask for etching on the non-metal sheet to generate the needed pattern. Its apparatus is also disclosed.

Description

technical field [0001] The invention relates to the technical field of applying laser to process workpieces, in particular to a method for processing the surface of non-metallic sheets such as wood veneer, bamboo veneer, acrylic and the like. Background technique [0002] At present, the laser galvanometer marking machine is a known processing equipment. Its working principle is to use low-power laser dot matrix scanning to generate a certain high temperature, and carbonize or burn the surface of non-metallic materials to achieve the purpose of printing marks and markings. As a result, its application to non-metallic marking processing is a relatively mature technology, especially widely used in the etching and printing of numbers and symbols on the chip surface. On the other hand, since the laser galvanometer marking machine directly acts on the surface of the material, its processing speed is fast and its efficiency is high. A better way to texture. However, in the tradi...
