After the sealing frame is filled with water, when the glass drilling tool rotates to drill, the water in the sealing frame will quickly conduct away the heat generated during drilling. This can prevent the glass at the processing location from being easily broken due to thermal expansion and contraction. It can also fill the cracks at the drilling location of the automotive glass, reduce the stress at the cracks, and effectively prevent the glass from cracking.

Ultimately, the equipment is positioned so that the waste collection bin is directly below the drilling location. This ensures that glass shards and water generated after drilling fall directly into the waste collection bin. The overall structural design allows the equipment to adjust the position of the waste collection structure below the drilling location, effectively improving the equipment's waste collection function.

[0030] Example 2:

[0031] Depend on Figures 1-6 As shown, this utility model provides a drilling device for automotive glass production; a pair of fourth electric slide rails 33 are symmetrically installed on the upper surface of the workbench 1, and a fourth electric slide block 23 is installed on the outer wall of the pair of fourth electric slide rails 33. A second fixing frame 19 is fixedly connected to the upper end face of the pair of fourth electric slide blocks 23. A third electric slide rail 22 is installed on both sides of the inner wall of the second fixing frame 19. A third electric slide block 21 is installed on the outer wall of the pair of third electric slide rails 22. A garbage collection basket 20 is fixedly connected between the outer walls of the pair of third electric slide blocks 21. The garbage collection basket 20 is located directly below the sealing frame 16. The fourth electric slide blocks 23 are installed on the fourth electric slide rails 33 to facilitate the longitudinal position adjustment of the garbage collection basket 20. The third electric slide blocks 21 are installed on the third electric slide rails 22 to facilitate the lateral position adjustment of the garbage collection basket 20. The second fixing frame 19 facilitates the installation of the garbage collection structure.

[0032] Both sides of the workbench 1 are fixedly connected to clamping seats 18. A pair of second hydraulic cylinders 17 are symmetrically installed on the upper end face of the pair of clamping seats 18. The telescopic ends of the pair of second hydraulic cylinders 17 are fixedly connected to limit plates 26. The lower end face of the pair of limit plates 26 is fixedly connected to anti-slip pads 32. The lower end face of the clamping seats 18 and the upper end face of the second fixed frame 19 are slidably connected. The clamping seats 18 are used to clamp and fix the automotive glass to be processed. The second hydraulic cylinders 17 and their connection with the limit plates 26 make it convenient to drive the limit plates 26 to clamp and fix the automotive glass on the clamping seats 18 through the second hydraulic cylinders 17. The anti-slip pads 32 set under the limit plates 26 can prevent the automotive glass from resonating or moving during processing, and can also avoid scratching the surface of the automotive glass.

[0033] Support legs 25 are fixedly connected to the four corners of the lower end face of the workbench 1, and cabinet doors 2 are symmetrically and rotatably connected to the front end face of the workbench 1. The support legs 25 serve to support the entire equipment, and the cabinet doors 2 facilitate the opening and closing of the workbench 1, the replenishment of water to the water tank 36 inside the workbench 1, and the maintenance and repair of the water pump 35.

[0034] Working principle: When the equipment of this application is used, the operator places the car glass in the clamping seat 18, and then the operator controls the second hydraulic cylinder 17 to work through the control terminal. The working second hydraulic cylinder 17 drives the limiting plate 26 and the anti-slip soft pad 32 to press down, clamping and fixing the car glass in the clamping seat 18, thus completing the fixing of the car glass.

[0035] After completing the above operations, the operator controls the second electric slide 9 to adjust its lateral position on the second electric slide rail 6 via the control terminal, controls the first electric slide 4 to adjust its longitudinal position on the first electric slide rail 3, and finally controls the drill bit holder 14 to move directly above the working position of drilling the car glass. At the same time, the operator controls the third electric slide 21 to adjust its lateral position on the third electric slide rail 22, and controls the fourth electric slide 23 to adjust its longitudinal position on the fourth electric slide rail 33, and finally controls the garbage collection bin 20 to move directly below the working position of drilling the car glass.

[0036] After positioning is completed, the operator controls the first hydraulic cylinder 10 to output through the control terminal. The output first hydraulic cylinder 10 drives the drill bit holder 14 to move down, so that the sealing frame 16 below the drill bit holder 14 covers the car glass. The sealing ring 28 at the lower end of the sealing frame 16 ensures the sealing between the sealing frame 16 and the car glass. Then, the operator controls the water pump 35 to work through the control terminal, pumping the water in the water tank 36 into the water supply bellows 8 along the output pipe 34, and finally into the sealing frame 16 along the water supply bellows 8. As the drill bit holder 14 continues to move down, when the glass drill bit 24 contacts the car glass, the operator controls the drilling motor 13 through the control terminal to drive the glass drill bit 24 to rotate at high speed to perform drilling operations on the car glass.

[0037] The water inside the sealing frame 16 will quickly conduct away the heat from the automotive glass processing area, and at the same time fill the cracks generated in the automotive glass processing area, effectively reducing the breakage rate of automotive glass during drilling.

[0038] After the glass drill bit 24 completes the drilling operation, the glass shards produced by drilling will fall directly into the trash can 20, and at the same time, the water in the sealing frame 16 will also flow down into the trash can 20 along the drilled hole.
