Description

Technical Field

[0001] This application relates to the field of laser engraving technology, and more specifically, to a product positioning fixture and laser engraving machine for laser engraving. Background Technology

[0002] A laser engraving machine uses a laser beam to carve permanent marks on the surface of a material or inside a transparent material. The laser beam can produce both chemical and physical effects on the material. When a material absorbs the laser light, a physical or chemical reaction occurs, thus creating marks, patterns, or text. Therefore, laser engraving machines are also known as laser marking machines or laser carving machines.

[0003] Laser engraving machines typically have product positioning fixtures to hold products in place for laser marking or engraving. However, existing product positioning fixtures are usually placed manually, which is not only wasteful of manpower and inefficient, but also prone to positioning errors. This can lead to inaccurate marking or engraving on the same location on the product, especially for products with small marking or engraving areas and requiring highly precise positioning.

[0004] Therefore, existing technologies still need to be improved. Utility Model Content

[0005] The purpose of this application is to provide a product positioning fixture and laser engraving machine for laser engraving, in order to solve the problem that existing product positioning fixtures are usually positioned manually, which not only wastes human resources and has low work efficiency, but also is prone to positioning errors. This will result in the inability to accurately mark or engrave the product at the same position when laser marking or laser engraving is performed, which is obviously unsuitable for products with small marking or engraving areas and particularly precise engraving positions.

[0006] To achieve the above objectives, the technical solution adopted in the first aspect of the embodiments of this application is as follows:
