Description

Technical Field

[0001] The utility model relates to the technical field of laser marking machines, in particular to a laser component used for laser marking machines. Background Art

[0002] Laser marking machine is an optical and mechatronic device that integrates laser technology and computer technology. Its working principle is that the laser generates laser, which is focused by the focusing lens and then irradiated to the surface of the marking object to form a mark on the marking object.

[0003] Specifically, the laser marking machine includes a laser component, which specifically includes a laser for generating a laser beam, an optical path mechanism for receiving the laser beam emitted by the laser, and a laser head for receiving the laser beam emitted by the optical path mechanism. After the laser head receives the laser beam emitted by the optical path mechanism, it is focused by a focusing lens and then irradiated onto the surface of the marking object to form a mark on the marking object.

[0004] In order to facilitate marking, the laser head of the laser assembly of the laser marking machine on the market is adjustable, and the laser head can be moved to the specified position for marking as needed. However, in the traditional method, whether the laser head moves horizontally or vertically, the laser assembly moves as a whole, so the driving power required for adjusting the position is relatively large.
