Laser marking machine provided with light focusing groove

Abstract

The invention discloses a laser marking machine provided with a light focusing groove. The laser marking machine comprises a base, a supporting column is arranged on the base, an adjusting shaft A isarranged on the supporting column, and the supporting column is connected with a laser cross beam through the adjusting shaft A. A laser is arranged on the laser cross beam, the laser comprises a laser generator, a light condensation cavity is connected to the front end of the laser generator, and the rear end of the laser generator is a total reflection mirror. An adjusting shaft B is arranged onthe supporting column, a workpiece groove is formed in the base, a guide rail is arranged on the workpiece groove, and the adjusting shaft B can adjust the relative positions of a workpiece and a laser beam. The laser marking machine provided with the light focusing groove can facilitate work of focal length adjusting of laser, and laser deviation caused by inaccuracy of manual laser focal lengthadjusting is reduced.

Description

technical field [0001] The invention relates to the technical field of laser equipment, in particular to a laser marking machine with an alignment groove. Background technique [0002] Laser equipment is more and more widely used in modern society. It is mainly used for laser cutting, laser welding, laser drilling, and laser marking. The laser beam is used to interact with the workpiece to be worked, and the surface of the workpiece is subjected to high-temperature heat treatment to complete industrial applications. [0003] In the laser marking work, after the laser generates laser light and passes through a set of optical systems, the laser beam passes through the marking head, and the laser marking head guides the laser beam to pass through the focusing lens to converge into a small light spot and mark on the surface of the object. However, the laser marking head must always maintain a fixed distance from the surface of the object, the focal length, the focal length of e...

Problems solved by technology

[0003] In the laser marking work, after the laser generates laser light and passes through a set of optical systems, the laser beam passes through the marking head, and the laser marking head guides the laser beam to pass through the focusing lens to converge into a small light spot and mark on the surface of the object. However, the laser marking head must always maintain a fixed distance from the surface of the object, the focal length, the focal length of each is determined by the focusing lens, and the beam will converge into a small light spot after passing through the focusing lens. As the focus, the workpiece to be processed is placed on the focus to achieve the best marking effect. In actual work, the laser is invisible, and the focus is invisible and intangible. It is not easy to determine. The existing focus positioning uses direct marking. It is cumbersome to determine with a ruler, and after the focus lens of the same marking machine is replaced, the focus needs to be readjusted, and the focal length error may cause the loss of the workpiece. Since the laser uses invisible light, it is more common to operate the laser without work experience. At the same time, the materials and structural shapes of the materials to be processed are not exactly the same, so the focus can be quickly positioned, which can improve work efficiency and save working time
