Description

Technical Field

[0001] This utility model relates to the field of laser engraving technology, and in particular to a laser engraving device. Background Technology

[0002] A laser engraving and cutting machine focuses a laser beam emitted from a laser source into a laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized material. As the relative position of the beam and the workpiece moves, the material is ultimately textured or cut, thus achieving the purpose of engraving or cutting.

[0003] However, existing laser engraving and cutting methods, because the laser generators output lasers vertically downwards, are limited by height and space. When engraving cylindrical objects, the laser engraving and cutting machine is raised and a rotating accessory is added to the bottom of the machine to achieve the engraving or cutting of cylindrical objects. Raising the laser engraving and cutting machine poses a risk of laser exposure, and the raising accessory is also required, which is costly.

[0004] Therefore, there is an urgent need for a laser engraving device to solve the above-mentioned technical problems. Utility Model Content
