Description

Technical Field

[0001] The utility model relates to a nano-texture laser engraving device for a tire mold side plate. Background Art

[0002] As wealth improves, consumers are pursuing both practicality and aesthetics. This is also true for the tire industry. To enhance the aesthetics of tire sidewalls, the industry has introduced nanotexturing, which increases the blackness of light traps and enhances the tactile quality of the sidewalls. The three-dimensional structure of the nanotexturing allows the sidewalls to absorb more light without reflecting it, resulting in a blackness closer to pure black than conventional tires. It can even create a gradient visual effect as light shifts, giving the tires a unique, high-end character.

[0003] Most of the engraving and milling machines on the market are only suitable for processing fonts and patterns on the side panels of conventional tire molds. Since nano-texture engraving cannot be processed using conventional tools, it requires cutting-edge precision equipment for engraving. Summary of the Invention

The beam expander moves linearly along the Z1 axis to dynamically change the focal position of the laser. The control system sets the processing path according to the graphic template preset by the upper computer software, and converts the preset graphic template into a driving signal through the control board. The driving signal controls the X1-axis galvanometer to deflect around the X1 axis, the Y1-axis galvanometer to deflect around the Y1 axis, and the beam expander to move along the Z1 axis, so that the X1-axis galvanometer, Y1-axis galvanometer lens, and Z1-axis beam expander move in combination. The laser beam generated by the laser first passes through the beam expander and focusing lens to change the focal position, and then is refracted by the X1-axis galvanometer and Y1-axis galvanometer and then passes through the field lens to quickly move on the workpiece surface in the scanning and engraving area to perform three-dimensional surface engraving.

[0006] In the utility model, a chuck is arranged at the middle of the rotary worktable, and the central axis of the workpiece is made to coincide with the rotary axis of the rotary worktable through the clamping claws of the chuck.

[0007] The utility model provides a plurality of feet for adjusting the level on the bottom surface of the bed.

[0008] The utility model has the following positive effects: the bed adopts a three-axis machine tool structure, which does not require complex motion and multi-axis linkage. The three-axis machine tool performs high-speed and high-precision processing. The three-axis structure has high stability and reliability, and motion control is relatively easy, which can ensure long-term continuous processing without failure, thereby ensuring high efficiency and stability of product quality; through the Z1-axis optical system, the 3D galvanometer laser system can freely change the focus position to perform three-dimensional curved surface engraving on the tire mold side panel.
