Laser device for laser marking machine

Abstract

The invention discloses a laser device for a laser marking machine. The laser device comprises a rack plate and a laser positioning mechanism, wherein a laser head is fixed on the laser positioning mechanism, and a light source fixed mount is fixed on a position on the laser positioning mechanism, which is close to the laser head; the light source fixed mount comprises a light source fixed plate and a pair of light source fixed blocks, wherein the light source fixed blocks are symmetrically fixed on the laser positioning mechanism; a shaft hole and an annular hole are arranged in each light source fixed block, and each annular hole takes the center of the shaft hole as a center of a circle; a pair of cylindrical clamping platforms are both fixed at two sides of the light source fixed plate, and the cylindrical clamping platforms at two sides of the light source fixed plate are respectively clamped in the shaft hole and the annular hole of the corresponding light source fixed block; an annular light source is fixed at the bottom end of the light source fixed plate and is corresponding to the laser head; and a CCD (Charged Coupled Device) camera is fixed at the upper end of the light source fixed plate. Through the way, the laser device can utilize a CCD image system to position automatically, and the laser head is quickly transmitted to an appointed position to carry out marking work; and a camera side is convenient for positioning adjustment, and the flexibility is high.

Description

technical field [0001] The invention relates to the field of marking machine laser devices, in particular to a laser device for a laser marking machine. Background technique [0002] The laser marking machine is mainly used for engraving 1D / 2D text patterns on PCB printed circuit boards for high-speed engraving to achieve beautiful and clear printing effects; the laser head of the existing marking machine cannot move to the designated position quickly and accurately; The position of the CCD camera cannot be adjusted arbitrarily as needed. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a laser device of a laser marking machine, which can automatically position the laser head by using the CCD imaging system, and quickly send the laser head to the designated position for marking work; the side-mounted camera is convenient for adjustment, positioning and code reading , high flexibility and wide application range. ...
