A control frame for laser marking and engraving equipment

Abstract

The invention discloses a control frame for laser marking and engraving equipment, which includes a bracket, legs are installed under the bracket, a vertical rod is fixedly connected to the surface of the bracket, the vertical rod is connected with a mounting plate through a height adjustment mechanism, and the mounting plate The sliding block is installed through the driving mechanism, and two splints are movably installed on the sliding block, and the laser modules are clamped in the two splints. The laser emitted by the group engraves and marks the material, and is connected with the laser module in the form of a splint, which can be replaced conveniently and quickly, and can be adapted to various types of laser modules. Two sides of the laser module are set The pipeline is used to blow and clean the surface of the material and collect the exhaust gas, which can prevent the hot-melt or gasified substances from accumulating on the surface of the engraving, thereby improving the laser effect.

Description

technical field [0001] The invention relates to the technical field of laser equipment, in particular to a control frame for laser marking and engraving equipment. Background technique [0002] With the gradual maturity and application development of laser technology, the technology of engraving and marking metal, plastic, wood and other materials with laser has been widely used in industry. Laser marking is to use its high energy density laser to locally irradiate the workpiece, and the focused laser acts on the printing material to melt or even vaporize the surface of the object. By controlling the path of the laser on the surface of the material, the required graphics and text are formed. mark. [0003] First of all, in order to improve the efficiency and effect of laser engraving and marking, the distance between the object and the laser module needs to be set according to the focal length of the module. During the process, it is necessary to adjust the distance betwee...

Problems solved by technology

[0003] First of all, in order to improve the efficiency and effect of laser engraving and marking, the distance between the object and the laser module needs to be set according to the focal length of the module. During the process, it is necessary to adjust the distance between the laser module and the object in real time, so as to make up for the distance difference. Most of the equipment now directly uses the drive motor and the screw to cooperate, and then controls and changes the height of the laser module as needed. However, this The accuracy of the method depends on the rotation accuracy of the screw, and the horizontal torque will be generated during the movement, which will cause deviation or vibration

[0004] In addition, laser engraving and marking basically make the surface of the object melt or vaporize to produce depth changes. If the melted substance is not peeled off the surface in time, or the vaporized substance forms a mist and gathers in the air passing by the laser, it will affect The effect of engraving and marking
