Technical Field

Therefore, it is very necessary to perform black marking on transparent materials. Utility Model Content

By placing the transparent material to be marked between the target plate and the laser galvanometer, the laser emitted by the laser galvanometer is focused on the contact surface between the target plate and the transparent material.

[0021] Reference Figure 1 The utility model provides a transparent material marking device, including a lifting workbench, a laser galvanometer 4 and a laser 1; the laser galvanometer 4 is installed on the laser light path emitted by the laser 1; the lifting workbench is detachably mounted with a target plate 7; the target plate 7 is provided with a processing surface that fits with the workpiece to be processed; the processing surface is located within the irradiation range of the laser galvanometer 4.

[0022] When in use, the transparent material to be marked, such as a glass substrate 6, is fixed on the processing surface of the target plate 7 so that the lower surface of the glass substrate 6 is tightly fitted with the processing surface of the target plate 7. Start the laser 1 to generate a laser beam, and the laser enters the laser galvanometer 4 and irradiates the surface of the target plate 7. Start the lifting platform, adjust the relative position of the target plate 7 and the laser galvanometer 4 on the Z axis, and focus the laser beam on the interface between the glass substrate 6 and the target plate 7. When marking begins, under the continuous action of the laser beam, the laser galvanometer 4 controls the deflection of the laser beam in the XY plane according to the desired marking shape to achieve marking of the glass substrate 6. After the laser marking is completed, turn off the laser 1, remove the glass substrate 6, and you can get a glass substrate 6 marked with laser black. After the equipment has been used for a period of time, it can be replaced according to the condition of the target plate 7 itself.

[0023] Specifically, the lifting workbench includes a lifting rail 10, a lifting slider 9 and a working panel 8; the lifting slider 9 is slidably mounted on the lifting rail 10; the working panel 8 is connected to the lifting slider 9; and the target plate 7 is mounted on the working panel 8.

[0024] Optionally, a field lens 5 is installed at the laser outlet of the laser galvanometer 4, and the laser light passing through the laser galvanometer 4 is focused and irradiated onto the surface of the target material through the field lens 5 to achieve high-resolution marking.

[0025] Furthermore, a beam expander assembly is provided on the optical path between the laser 1 and the laser galvanometer 4. The laser light emitted by the laser 1 is expanded and shaped by the beam expander assembly and then enters the laser galvanometer 4.

[0026] Specifically, the beam expander assembly includes a beam expander 3 and a bracket 2; the beam expander 3 is mounted on the bracket 2, and the beam expander 3 is located on the optical path between the laser 1 and the laser galvanometer 4.

Through the intense ablation of the target material by the laser, under the action of instantaneous high temperature, the target material particles fall off from the surface at a high speed and adhere to the surface of the transparent material, thereby realizing black marking with high contrast on the surface of the transparent material. The mark has strong stability and durability, which is conducive to the development of the application of laser marking technology in the field of transparent materials.
