High-speed dynamic focusing laser vibrating mirror module group

Abstract

The invention relates to a high-speed dynamic focusing laser vibrating mirror module group, and aims at providing a dynamic focusing laser vibrating mirror which is high in degree of integration, fine in marking and stable in performance. The high-speed dynamic focusing laser vibrating mirror module group comprises a shell, a dynamic focusing module, an X scanning vibrating mirror and a Y scanning vibrating mirror. The dynamic focusing module, the X scanning vibrating mirror and the Y scanning vibrating mirror are arranged in the shell. The dynamic focusing module comprises a Z-axis base, a Z-axis first motor, a Z-axis second motor, a connecting rod transmission mechanism, a zooming lens and a focusing lens set. The Z-axis adopts a double motor driving mode so that operation speed of the Z-axis can be greatly enhanced; and the dynamic focusing module is combined with the X scanning vibrating mirror and the Y scanning vibrating mirror so that the degree of integration of the product can be greatly enhanced. A shading base, the zooming lens and the focusing lens set are integrally assembled so that coaxiality of a light path can be guaranteed, high-precision and compact design of motor assembling and the light path system is performed in the whole structure, precise marking of a curved surface or large breadth is guaranteed and the overall size is reduced for one third in comparison with that of similar products.

Description

technical field [0001] The invention relates to the technical field of laser marking, in particular to a high-speed dynamic focusing laser galvanometer module. Background technique [0002] With the development of laser processing technology, the emergence of three-dimensional dynamic focusing system using dynamic optical control technology overcomes the phenomenon of small processing format and uneven focus spot in traditional laser marking and laser engraving systems, and is widely used in high-end industrial manufacturing Large format marking and three-dimensional surface marking in the fields of electronics, medical and handicrafts. Most of the dynamic focusing galvanometers currently on the market have defects such as slow speed, low precision, and large size, which cannot meet the application requirements of new industries and high-end fields. However, the dynamic focusing galvanometers produced by foreign laser galvanometer manufacturers have Defects such as complex ...
