The rotator 16 is fixedly installed on the front end of the mounting plate 15.

[0035] Principle: After the drive motor 12 starts, the output end of the drive motor 12 drives the threaded rod 13 to rotate. The threaded rod 13 causes the mounting plate 15 to move steadily left and right along the slide rod 14, thereby adjusting the horizontal position of the laser emitter 17 to meet the engraving needs of wheels of different sizes.

[0036] Rotator 16 can drive laser emitter 17 to rotate, flexibly adjusting the laser emission angle.

[0037] The smoke collection duct 18 is connected to an external smoke purifier, which can collect the smoke generated during laser engraving in a timely manner, reducing the harm of harmful gases and dust to the working environment and the health of operators, while ensuring a clear view of the processing area and improving engraving accuracy.

[0038] The infrared emitter 19 is installed at the front end of the laser emitter 17. It can accurately locate the position of the wheel air hole before engraving, providing a key coordinate reference for subsequent precise engraving, ensuring that the position of the engraved pattern is accurate, and improving the precision, flexibility and environmental friendliness of laser engraving operations.

[0039] The laser emitter 17 is connected to the focus adjustment assembly 2, and the mounting bracket 11 is connected to the position adjustment assembly 31.

[0040] The focal length adjustment assembly 2 includes a motor 21, a mounting lens barrel 22, a threaded rod 23, a threaded block 24, and a focusing lens 25.

The focusing lens 25 is slidably connected to the inside of the mounting lens barrel 22.

[0041] When the focus needs to be adjusted, the motor 21 starts, and the motor 21 drives the threaded rod 23 to rotate. The threaded rod 23 drives the threaded block 24 to move, and the threaded block 24 drives the focusing lens 25 to move, thereby adjusting the distance between the laser emission port and the focusing lens 25, completing the focus adjustment and meeting diverse work needs.

[0042] The position adjustment assembly 31 includes a rotary table 311, a stepper motor 312, a drive block 313, and a mounting platform 314.

[0044] The clamping and fixing assembly 32 includes an L-shaped connecting rod 321, a slider 322, and an arc-shaped clamping plate 323. One end of the L-shaped connecting rod 321 is rotatably connected to the driving block 313, and the other end of the L-shaped connecting rod 321 is rotatably connected to the lower end of the slider 322. The slider 322 is slidably connected to the sliding groove 315, and the upper end of the slider 322 is fixedly connected to the arc-shaped clamping plate 323.

[0045] Multiple sliding grooves 315, L-shaped connecting rods 321, sliders 322, and arc-shaped clamps 323 are provided and are located around the drive block 313.

[0046] The rotator 16 and the rotary table 311 employ existing, mature technologies.

[0047] Before laser engraving the wheels, two compatible paints are selected, with strong color contrast and significant differences in their laser reflection and absorption properties; red and black paints are currently the most commonly used.

[0048] First, spray a red coating on the designated location on the wheel (4-5mm above the air vent). After the coating has cured, spray a black coating on top to complete the product coating.

[0049] Then the wheel is placed on the slider 322, the stepper motor 312 is started, the stepper motor 312 drives the drive block 313 to rotate, the drive block 313 drives the L-shaped connecting rod 321 to rotate, the L-shaped connecting rod 321 drives the slider 322 to slide in the sliding groove 315, the sliding groove 315 drives the arc-shaped clamping plate 323 to move, thereby clamping the wheel in several directions.

[0050] After clamping, the rotating worktable 311 drives the mounting table 314 to rotate until the infrared emitter 19 detects the air hole of the wheel. The infrared emitter 19 is positioned 4-5mm above the air hole of the wheel. Through the projection function of the 3D model on the laser machine, the engraved pattern is projected onto the product. The laser emitter 17 begins to engrave the specified pattern, gradually removing the black coating on the surface to reveal the red coating at the bottom, ultimately forming a pattern and text with a contrast between red and black.

[0051] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
