Abstract
Description
Technical Field
[0001] The utility model relates to an adjusting device, in particular to a precise adjusting device for laser marking on the surface of optical glass. Background Art
[0002] Laser marking is a process in which a laser generator generates a high-energy continuous laser beam. The focused laser acts on the substrate, causing the surface material to melt instantly or even vaporize. The path of the laser on the surface of the material is controlled to form the required graphic mark. Optical glass has extremely high requirements for surface graphic marks, and its graphic marks require clear handwriting, fine processing, and precise size and position. Compared with traditional mechanical engraving methods, laser marking has significant advantages in marking graphics on the surface of optical glass. It has very high precision and flexibility. Laser marking is a non-contact process that can easily engrave clear and fine text or patterns on glass of various shapes and sizes. Its mark is wear-resistant, and the generation process is easy to automate. The marked workpiece will not deform and produce internal stress. It is very suitable for marking graphics on the surface of optical glass. Utility Model Content
