Laser marking control method, laser marking head and laser marking machine

Abstract

The invention provides a laser marking control method, a laser marking head and a laser marking machine. The laser marking head comprises a laser generator for emitting lasers, a first guide rail, a first sliding device capable of sliding along the first guide rail, a first reflector fixed to the first sliding device, a second guide rail fixed to the first sliding rail and perpendicular to the first guide rail, a second sliding device capable of sliding along the second guide rail, and a second reflector fixed to the second sliding device. The lasers emitted by the laser generator are parallel to the first guide rail and enter the first reflector in an incident mode, the first reflector reflects the lasers to the second reflector, the lasers reflected by the first reflector are parallel to the second guide rail, the second reflector reflects the lasers downwards, and then marking is positioned. By the adoption of the mode, the laser marking head is smaller in size and capable of achieving large-width and large-span marking operation.

Description

technical field [0001] The invention relates to the technical field of laser control, in particular to a laser marking control method, a laser marking head and a laser marking machine. Background technique [0002] Laser marking machine refers to the equipment that uses laser beams to irradiate objects to evaporate the surface of the object to expose deep substances, so as to engrave patterns, trademarks and text on the surface of the object. According to the laser generation method, the laser marking machine is mainly divided into: carbon dioxide laser marking machine, semiconductor laser marking machine, fiber laser marking machine and so on. [0003] In order to draw exquisite marks on the surface of the object, it is necessary to accurately control the position of the laser output by the laser marking head in the laser marking machine on the object. In the prior art, the laser emitted by the laser generator in the laser marking head is incident on two reflectors, and th...

AI Technical Summary

Problems solved by technology

The method of controlling the deflection of the laser beam by controlling the reflection angle of the mirror requires a large open space, which makes the laser marking head too large and takes up a lot of space. In addition, due to the limitation of the reflection angle, the laser The marking machine cannot achieve large-format marking operations
