[0035] The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] The specific embodiments described below are merely preferred embodiments of this application, and the scope of protection of this application is not limited thereto. Those skilled in the art can make modifications or variations based on the principles, concepts, and spirit of this application, and the resulting technical solutions should all be covered within the scope of protection of this application.

[0037] like Figure 1-7As shown, the glass grinding device includes a support plate 1, an intermediate connecting plate 2, a main frame 3, a grinding wheel seat 4, a grinding wheel 5, a circular cover 6, a grinding fluid connector 7, a water inlet connector 8, a water pipe 9, a nozzle 10, a spray head 11, a sealing cover 12, a first upper annular sealing gasket 13, a second upper annular sealing gasket 14, a first lower annular sealing gasket 15, a second lower annular sealing gasket 16, screws 17 and 18, an annular guide rail 19, a guide wheel 20, a connecting seat 23, and an eccentric shaft 24. The intermediate connecting plate 2 is fixedly connected to the support plate 1, and the main frame 3 is fixedly connected to the intermediate connecting plate 2. The grinding wheel seat 4 is equipped with... The grinding wheel seat 4, located at the intermediate connecting plate 2, passes through the main frame 3 and extends downwards. The grinding wheel 5 is fixedly connected to the lower end of the grinding wheel seat 4, and the upper end of the grinding wheel seat 4 is used to connect to the output shaft of the drive motor. The drive motor drives the grinding wheel seat 4 to rotate at high speed, and the grinding wheel seat 4 drives the grinding wheel 5 to rotate at high speed. The circular cover 6 is fixedly connected to the bottom of the main frame 3. The grinding wheel 5 is located in the space between the circular cover 6 and the bottom of the main frame 3. The grinding wheel 5 rotates at high speed in this space. The circular cover 6 has a slit 6-1, through which the edge of the glass to be ground extends so as to abut against the grinding wheel 5 and be ground by the grinding wheel 5. The grinding fluid connector 7 is connected to the support plate 1, and the nozzle 11 is connected to the grinding fluid connector 7. The nozzle 11 is close to the grinding wheel 5. The external grinding fluid enters from the grinding fluid connector 7 and is then output from the nozzle 11 to the grinding wheel 5 and the edge of the glass. The support plate 1 is fixedly installed on the rotary mechanism of the automatic glass processing equipment. The rotary mechanism is equipped with a drive motor for driving the grinding wheel seat to rotate. The output shaft of the drive motor is connected to the upper end of the grinding wheel seat 4. The operation of the rotary mechanism can make the support plate 1, the intermediate connecting plate 2, the main frame 3, the grinding wheel seat 4, the grinding wheel 5 and the circular cover 6 rotate as a whole to adapt to the entire grinding path of the glass edge (since the glass to be ground is stationary, the edge of the glass always extends into the gap 6-1). The rotary mechanism is installed on the XY linear module of the automatic glass processing equipment. The operation of the XY linear module can drive the rotary mechanism to move to any position on the horizontal plane, that is, to move the grinding wheel 5 to any position on the horizontal plane, thereby adapting to the entire grinding path of the glass edge.

[0038] The water inlet connector 8 is connected to the support plate 1, the water pipe 9 is connected to the water inlet connector 8, the nozzle 10 is connected to the water pipe 9, the nozzle 10 is located in the space between the circular cover 6 and the bottom of the main frame 3, and the nozzle 10 is close to the grinding wheel 5. The sealing cover 12 is fitted around the main frame 3. The sealing cover 12 has an outlet 12-1. The space between the circular cover 6 and the bottom of the main frame 3 is connected to the outlet 12-1. The first upper annular sealing gasket 13 is fixedly connected to the upper part of the outer perimeter of the main frame by screws 17. The cross-section of the first upper annular sealing gasket 13 is L-shaped. The second upper annular sealing gasket 14 is fixedly connected to the upper part of the inner side of the sealing cover 12 by screws 18. The second upper annular sealing gasket 14 is in contact with the first upper annular sealing gasket 13. The first lower annular sealing gasket 15 is fixedly connected to the lower part of the outer perimeter of the main frame by screws. The cross-section of the first lower annular sealing gasket 15 is L-shaped. The second lower annular sealing gasket 16 is fixedly connected to the lower part of the inner side of the sealing cover 12 by screws. The second lower annular sealing gasket 16 is in contact with the first lower annular sealing gasket 15. It can be seen that the first upper annular sealing gasket 13 and the second upper annular sealing gasket 14, as well as the first lower annular sealing gasket 15 and the second lower annular sealing gasket 16, achieve a gapless seal.

[0039] The annular guide rail 19 is fixedly mounted on the support plate 1 by screws. The outer side of the annular guide rail 19 has a V-shaped part 19-1. The connecting seat 23 has a connecting hole 23-1. The fastening screw 25 passes through the connecting hole 23-1 and connects to the sealing cover 12, thereby fixing the connecting seat 23 to the sealing cover 12. After loosening the fastening screw 25, the connecting seat 23 can be moved up and down in the vertical direction to adjust the position of the connecting seat 23. After the position is adjusted, the fastening screw 25 is tightened. The figure shows two fastening screws 25 and two corresponding connecting holes, which is a preferred technical means. The guide wheel 20 is fitted onto the eccentric shaft 24. The eccentric shaft 24 has a guide wheel positioning platform 24-1, which supports the guide wheel 20. The eccentric shaft 24 has a central through hole. The eccentric shaft positioning screw 26 passes through the central through hole and connects to the connecting seat 23. The guide wheel 20 can rotate with the eccentric shaft 24 as a reference. The guide wheel 20 has a V-shaped annular groove 20-1. The V-shaped part 19-1 of the annular guide rail 19 is embedded in the V-shaped annular groove 20-1, and the guide wheel 20 cooperates with the annular guide rail 19. Loosen the eccentric shaft positioning screw 26, and then rotate the eccentric shaft 24 to adjust the position of the eccentric shaft 24. Then, adjust the position of the guide wheel 20 in the front-back direction (closer to or further away from the V-shaped part 19-1 of the annular guide rail 19). After adjusting the position, tighten the eccentric shaft positioning screw 26. By adjusting the front-to-back position and the up-to-down position of the guide wheel 20, a good fit between the guide wheel 20 and the V-shaped part 19-1 of the annular guide rail 19 can be ensured, guaranteeing smooth and stable relative movement between the guide wheel and the annular guide rail 19.

[0040] The figure also shows that guide wheels 21 and 22 are provided, for a total of three guide wheels. The installation method of guide wheels 21 and 22 is the same as that of guide wheel 20. The three guide wheels are evenly distributed along the circumference. Three guide wheels are the preferred technical means. Those skilled in the art will understand that only one guide wheel, two guide wheels, four guide wheels, or more guide wheels can also be provided.

[0041] When using the above-mentioned glass grinding device, the support plate 1 is fixedly installed on the rotary mechanism of the automatic glass processing equipment (the rotary mechanism is connected to the XY linear module of the automatic glass processing equipment), see reference. Figure 5 The apparatus consists of a rigid drainage channel 27, a rigid telescopic pipe 28, and a fixed column 29. One end of the rigid drainage channel 27 is connected to the outlet 12-1 of the sealing cover 12, and the other end is connected to the front end of the rigid telescopic pipe 28. The rear end of the rigid telescopic pipe 28 is rotatably connected to the fixed column 29, which supports the rigid telescopic pipe 28. Both the rigid drainage channel 27 and the rigid telescopic pipe 28 are located in a horizontal plane, while the fixed column 29 is located in a vertical direction. The entire glass grinding apparatus is located in a horizontal plane. The rigid telescopic pipe 28 has two sections (a front section and a rear section). The front section, connected to the rigid drainage channel 27, can extend and retract with the rear section as a reference.

[0042] The grinding wheel 5 rotates at high speed to grind the edges of the glass. External cleaning water enters through the water inlet 8, then flows through the water pipe 9, and finally sprays out from the nozzle 10 onto the glass edges to clean them. Air is drawn out through the rigid telescopic pipe 28, and the resulting water mist flows from the space between the circular cover 6 and the bottom of the main frame 3 to the outlet 12-1 of the sealing cover 12, and then flows out through the rigid drainage channel 27 and the rigid telescopic pipe 28 before being discharged. Similarly, the used grinding fluid in the space between the circular cover 6 and the bottom of the main frame 3 can also flow out from the outlet 12-1, then through the rigid drainage channel 27 and the rigid telescopic pipe 28 before being discharged.

[0043] The glass grinding device moves along the trajectory of the glass edge, and the sealing cover 12 moves relative to the main frame 3. With the cooperation of the guide wheel and the annular guide rail 19, the sealing cover 12 and the main frame 3 move relative to each other in the horizontal plane, preventing the sealing cover 12 from shifting or vibrating vertically. This ensures a good seal and reduces wear on the first upper annular sealing gasket 13, the second upper annular sealing gasket 14, the first lower annular sealing gasket 15, and the second lower annular sealing gasket 16, preventing damage to the four gaskets and extending the service life of the gaskets and sealing cover 12 while maintaining a good seal. Especially when the rotary mechanism rotates, driving the support plate 1 and the annular guide rail 19 to rotate, it prevents the sealing cover 12 from shifting or vibrating vertically, further ensuring a good seal, reducing wear on the four gaskets, and preventing damage to them. If the seal is poor, cleaning water and grinding fluid will splash out, adversely affecting the grinding operation and contaminating the working area of ​​the glass processing equipment.

[0044] It should be noted that the mating of the first upper annular sealing gasket 13 and the second upper annular sealing gasket 14 is one specific implementation of the sealing element. Those skilled in the art will understand that sealing elements with other specific structures can also be used. The mating of the first lower annular sealing gasket 15 and the second lower annular sealing gasket 16 is one specific implementation of the sealing element, and sealing elements with other specific structures can also be used.
