[0019] The following further description of the present utility model will be given in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the examples given are not intended to limit the present utility model.

[0020] Combined with Figures 1-5 , the present application provides a laser beam optimization device, including a cylinder 1, the cylinder 1 includes an inlet 4, an outlet 3 and a light channel 5 located between the inlet 4 and the outlet 3, and the cross-sections of the inlet 4, the outlet 3 and the light channel 5 are all circular.

[0021] Among them, the radius of the outlet 3 is greater than the radius of the inlet 4, and a flange connection plate 12 is integrally connected to the cylinder 1 at the inlet 4, and it is convenient to be tightly and quickly connected to the laser generator through the flange connection plate 12.

[0022] Among them, a polarizer holder 7 and a wave plate holder 6 are fixedly installed on the cylinder 1, the polarizer holder 7 and the wave plate holder 6 are fixedly installed in the light channel 5, the polarizer holder 7 is closer to the outlet 3 relative to the wave plate holder 6, and the wave plate holder 6 is closer to the inlet 4 relative to the polarizer holder 7.

[0023] Specifically, the polarizer holder 7 is fixedly installed on the cylinder 1 by bolts, and the wave plate holder 6 is also fixedly installed on the cylinder 1 by bolts.

[0024] Moreover, a through hole is provided on the polarizer holder 7 and is communicated with the optical channel 5 to facilitate the conduction of light. A first polarizer 8 and a second polarizer 9 are mounted on the polarizer holder. Both the first polarizer 8 and the second polarizer 9 are mounted on the optical path of the through hole of the polarizer holder. Among them, the first polarizer 8 is closer to the entrance 4 than the second polarizer 9, and the second polarizer 9 is closer to the exit 3 than the first polarizer 8.

[0025] At the same time, a wave plate holder hole is provided on the wave plate holder 6 and is communicated with the optical channel 5. A wave plate 10 is mounted on the wave plate holder 6, and the wave plate 10 is mounted on the hole of the wave plate holder 6.

[0026] At the same time, in order to facilitate the placement of the polarizer holder 7 and the wave plate holder 6 in the optical channel 5, a mounting hole 11 is provided on the cylinder 1 and is communicated with the optical channel 5. The mounting hole 11 is semi-circular. In order to prevent light from flowing out of the mounting hole 11, a round cover 2 is fixedly mounted at the mounting hole 11. The round cover 2 is semi-circular, and the round cover 2 is fixedly mounted on the cylinder 1 by means of bolts.

[0027] At the same time, a layer of rubber pad is attached to the surface of the round cover 2 facing the cylinder 1, thereby increasing the sealing performance at the connection between the two and further preventing the outflow of light.

[0028] During specific operation, the laser emitted from the laser passes through the entrance and enters the optical channel. Then, it passes through the wave plate 10 to split the laser into two kinds of light, vertical and horizontal. Then, it passes through the first polarizer 8 and the second polarizer 9. The vertical light generated by passing through the wave plate 10 can be blocked, and the horizontal light can pass through, making the light more monochromatic and consistent. Although a part of the energy is lost, the quality of the light speed is improved. Only the horizontal light is left to be emitted from the exit for cutting the product, so that chipping can be reduced during product cutting and the quality of product cutting is improved.

It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the creation of the present utility model.
