Abstract

The invention relates to a high-speed dynamic focusing laser vibrating mirror module. Its purpose is to provide a dynamic focusing laser galvanometer with high integration, fine marking and stable performance. The present invention includes a housing, 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 all arranged inside the housing. Axis first motor, Z-axis second motor, connecting rod transmission mechanism, zoom lens and focusing lens group. The Z-axis is driven by dual motors, which greatly improves the running speed of the Z-axis; the dynamic focus module is combined with the X scanning galvanometer and the Y scanning galvanometer, which greatly improves the integration of the product. The light-shielding seat, zoom lens and focusing lens group are integrated to ensure the coaxiality of the optical path. The overall structure has a high-precision and compact design for the motor assembly and optical path system, which ensures precise marking on curved surfaces or large formats. , the overall volume is one-third smaller than 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 ...
