Problems solved by technology

The disadvantage of this method is that the laser light path moves in an open space, which is easily disturbed by dust in the air, and the field lens is fixed on the casing alone, and its relative position relative to the Y galvanometer and X galvanometer is unstable. It is necessary to reserve a larger range for the field lens

Abstract

The invention provides a closed scanning galvanometer device for a laser machine. The device comprises a base, an X galvanometer mechanism, a Y galvanometer mechanism and a field lens mechanism. The Xgalvanometer mechanism comprises an X galvanometer motor, an X galvanometer lens and an X galvanometer base which is provided with an X positioning hole, the Y galvanometer mechanism comprises a Y galvanometer motor, a Y galvanometer lens and a Y galvanometer base which is provided with a Y positioning hole, the field lens mechanism comprises a field lens, the front end of the base is provided with a laser incidence hole, the bottom of the base is provided with a field lens installation hole, the field lens is installed in the field lens installation hole, the X positioning hole, the Y positioning hole, the field lens installation hole and the laser incidence hole are mutually connected in a cavity, and the cavity is provided with no other through hole except for the X positioning hole, the Y positioning hole, the field lens installation hole and the laser incidence hole. The scanning galvanometer device fixes the Y galvanometer motor, the X galvanometer motor and the field lens, therelative positions are more stable, the closed cavity is formed in the base after fixing, and dust pollution is small when a laser beam passes.

Description

technical field [0001] The invention relates to a sealed scanning vibrating mirror device for a laser machine. Background technique [0002] The basic principle of laser marking is that a high-energy continuous laser beam is generated by a laser generator, and the focused laser acts on the printing material to instantly melt or even gasify the surface material. By controlling the path of the laser on the surface of the material, a Graphical markup required. [0003] Laser marking is characterized by non-contact processing, which can be marked on any special-shaped surface without deformation and internal stress on the workpiece. It is suitable for marking metal, plastic, glass, ceramics, wood, leather and other materials. [0004] Lasers can mark almost all parts (such as pistons, piston rings, valves, valve seats, hardware tools, sanitary ware, electronic components, etc.), and the marks are wear-resistant, the production process is easy to automate, and the deformation of...
