The rotation angle of the electric conveying roller 22 can be accurately controlled by the stepper motor 19, and the rotation angle of the electric conveying roller 22 can be controlled according to the thickness of the ultra-thin photovoltaic glass to adapt to ultra-thin photovoltaic glasses of different thicknesses. The electric conveying roller 22 conveys the ultra-thin photovoltaic glass with holes to the right, and conveys the ultra-thin photovoltaic glass with holes to the conveyor 14. The conveyor 14 conveys the ultra-thin photovoltaic glass with holes to the right.

The front and rear sides of the lifting frame 17 are connected to the second push plates 34 by bolts, and the sides where the two second push plates 34 are away from each other are provided with second inclined surfaces 35.

[0047] The first push plate 31 pushes the slide plate 29 and the second push plate 34 pushes the slide plate 29 to move away from each other. The spring 33 is compressed, and the first inclined surface 32 of the first push plate 31 and the slide plate 29 are gradually separated. The slide plate 29 moves downward under the action of its own gravity, and the roller 30 also moves downward, and the height of the roller 30 is lower than the top of the placement plate 5. , the ultra-thin photovoltaic glass will fall onto the placement plate 5. At this time, the cylinder 15 is closed, and then the ultra-thin photovoltaic glass is punched. After the punching is completed, the movable end of the cylinder 15 continues to shorten, the lifting frame 17 and the second push plate 34 continue to move upward, and the second push plate 34 slides on the vertical surface 311 of the first push plate 31, so that the first push plate 31 will not continue to move. After the conveyor 14 sends out the punched ultra-thin photovoltaic glass, the movable end of the cylinder 15 is controlled to extend, driving the second push plate 34 to move downward. After the second push plate 34 and the first push plate 31 are out of contact, under the action of the spring 33, the two first push plates 31 move towards each other, and the first push plate 31 pushes the slide plate 29 to move upward through the first inclined surface 32, and the slide plate 29 drives the roller 30 to move upward, so that the height of the roller 30 is higher than the top of the placement plate 5. When the movable limit plate 12 moves, the roller 30 needs to be lowered first, so that the height of the roller 30 is lower than the top of the placement plate 5 to avoid collision between the movable limit plate 12 and the roller 30.

The front side of the frame 352 is connected to the air inlet pipe 353. The air inlet pipe 353 is tilted so that the air inlet pipe 353 can be aligned with the punching position to accurately spray the inert gas to the punching position.

[0049] When drilling holes in the ultra-thin photovoltaic glass, the telescopic rod of the electric push rod 351 is controlled to extend, driving the frame 352 to move downward so that the bottom of the frame 352 contacts the top of the ultra-thin photovoltaic glass. The frame 352 can help control and collect dust generated during drilling, keep the working environment clean, and reduce safety hazards. The moving distance of the frame 352 can be accurately controlled by the electric push rod 351, and the moving distance of the frame 352 can be controlled according to the thickness of the ultra-thin photovoltaic glass to adapt to ultra-thin photovoltaic glasses of different thicknesses. The air inlet pipe 353 can be connected to an inert gas, and the inert gas is sprayed to the drilling position through the air inlet pipe 353. The inert gas can isolate oxygen and prevent the ultra-thin photovoltaic glass from burning or oxidizing, thereby protecting the optical elements of the laser 44 from contamination. The bottom of the frame 352 contacts the top of the ultra-thin photovoltaic glass to form a relatively closed environment. With the continuous flow of inert gas, the escape of inert gas can be reduced to a certain extent, thereby improving the utilization rate of inert gas.
