The first adjusting component and the second adjusting component cooperate to adjust the horizontal distance and the vertical distance between the four adsorption seats.

[0013] Using the above-mentioned grinding device for the surface of tempered glass, the grinding method includes the following steps; S1. The conveyor belt inputs the tempered glass before grinding and outputs it after grinding. The conveyor belt sends the unground tempered glass to one side of the grinding water bin. The entire grinding mechanism is driven to move by the transverse movement component. At the same time, the feeding mechanism and the grinding head are driven to change positions by the first motor, so that the feeding mechanism is located below. When the feeding mechanism is above the tempered glass, the hydraulic cylinder works to drive the feeding mechanism to move downward. S2. According to the size of the tempered glass, the horizontal distance and the vertical distance between the four adsorption seats are adjusted by the first adjusting component and the second adjusting component. At the same time, the hydraulic cylinder continuously moves downward to drive the adsorption seat to fit the surface of the tempered glass for adsorption. S3. After adsorption, the hydraulic cylinder drives the tempered glass to move upward. At the same time, the transverse movement component works synchronously to move the glass to directly above the grinding water bin. At this time, according to the size of the tempered glass, a certain number of adsorption heads are pushed upward by the electric telescopic rod to push the suction cups out of the water surface. At this time, the first solenoid valve and the second solenoid valve are opened, so that the water in the suction cups and the connecting pipes flows into the water tank through the return pipe. Then the first solenoid valve and the second solenoid valve are closed. At the same time, the hydraulic cylinder drives the tempered glass to move upward, and cooperates with the electric telescopic rod to push the suction cups to fit the bottom of the glass. At this time, the air pump works to make the suction cups adsorb and fix the tempered glass. S4. After the tempered glass is fixed by the suction cups, the first motor drives the feeding mechanism and the grinding head to change positions, so that the grinding head is located below. When the grinding head is above the tempered glass, the hydraulic cylinder works to drive the grinding head to move downward, and the grinding head comprehensively grinds the surface of the tempered glass by the cooperation of the transverse movement component and the longitudinal movement component. S5. Before grinding, the electric telescopic rod drives the suction cup to reset. At this time, the tempered glass is located below the liquid level. Then the grinding head moves downward to grind the tempered glass below the liquid level. At the same time, the liquid spraying head on one side of the grinding head sprays liquid synchronously to the grinding position for cooling, and the sprayed water flow impacts the liquid level, resulting in wave flow on the liquid level, thereby accelerating the heat conduction in water and further accelerating the heat dissipation at the grinding area. S6. When one side of the tempered glass is ground, the hydraulic cylinder drives the grinding head to move upward. At the same time, the first motor drives the feeding mechanism to change positions with the grinding head again, and the electric telescopic rod pushes the tempered glass upward. Then, the adsorption head on a set of support seats adsorbs the tempered glass. The other set of support seats rotates inward by a certain degree driven by the second motor. When the support seat adsorbing the tempered glass moves upward completely, the second motor on this support seat drives the support seat to rotate inward by a certain degree, and aligns the adsorption seats on the two sets of support seats. At this time, through the operation of the double-headed motor, the tempered glass is moved to the adsorption seat on the other set of support seats and is adsorbed and fixed by the adsorption seat there. Then, this set of support seats works to send the tempered glass back to the grinding water tank, thus completing the flipping of the tempered glass. After that, the grinding work is repeated. When the grinding is completed, the ground tempered glass is sent to the conveyor belt by the feeding mechanism for outward transportation.

[0014] The beneficial effects of the present invention are as follows: By setting up a grinding water tank, the tempered glass is ground below the liquid level. The heat generated during the grinding of the tempered glass can be better carried away by the water flow. At the same time, multiple groups of adsorption heads are provided at the bottom of the grinding water tank. Through the setting of multiple groups of adsorption heads, different widths or shapes of the glass can be adsorbed and fixed to ensure the stability during glass grinding. Combining with the way of underwater grinding can more effectively avoid the cracking of the tempered glass during grinding, thereby increasing the grinding effect of the device. At the same time, the adsorption heads of the device are set below the liquid level. To ensure the normal operation of the adsorption heads, the device is provided with a return pipe and a first solenoid valve to ensure the normal operation of the adsorption heads and the recycling and reuse of the grinding liquid, further increasing the practicality of the device.

A plurality of adsorption mechanisms for adsorbing tempered glass are distributed in a rectangular array at the bottom of the grinding water bin 4. The number of adsorption mechanisms is determined according to the surface area of the grinding water bin 4. The larger the area, the more adsorption mechanisms; the smaller the area, the fewer adsorption mechanisms; The adsorption mechanism includes a notch 7, an adsorption head 8, a lifting assembly, a first hose 9, and an adsorption drive assembly. The adsorption drive assembly includes a negative pressure chamber 10, a return pipe 11, and a first solenoid valve 12. Multiple groups of notches 7 adapted to the adsorption head 8 are distributed at the bottom of the grinding water tank 4. The number of adsorption heads 8 and notches 7 is determined according to the area of the grinding water tank 4. A lifting assembly for driving the adsorption head 8 to lift is provided on one side of the lower end of the adsorption head 8. A negative pressure chamber 10 is provided below the adsorption head 8. The negative pressure chamber 10 is fixed inside the installation chamber 5. The adsorption head 8 is connected to the negative pressure chamber 10 through the first hose 9.

The lower end of the return pipe 11 penetrates the connection surface of the installation chamber 5 and the water tank 6. A first solenoid valve 12 is provided on the return pipe 11.

[0019] By setting the grinding water tank 4, the tempered glass is ground below the liquid level. The heat generated during the grinding of the tempered glass can be better carried away by the water flow. At the same time, multiple groups of adsorption heads 8 are provided at the bottom of the grinding water tank 4. Through the setting of multiple groups of adsorption heads 8, different widths or shapes of the glass can be adsorbed and fixed, ensuring the stability during the grinding of the glass. Combining with the method of underwater grinding can more effectively avoid the cracking of the tempered glass during grinding, thereby increasing the grinding effect of the device. At the same time, the adsorption head 8 of the device is arranged below the liquid level. At this time, to ensure the normal operation of the adsorption head 8, the device is provided with a return pipe 11 and a first solenoid valve 12 to ensure the normal operation of the adsorption head 8 and the recycling and reuse of the grinding liquid, further increasing the practicability of the device.

[0020] The adsorption head 8 includes a suction cup 13, a connecting pipe 14, a second solenoid valve 15, and a fixing ring 16. A connecting pipe 14 is fixed to the bottom of the suction cup 13.

[0022] The negative pressure chamber 10 includes a chamber body 18, a honeycomb partition 19, and an air pump 20. An air pump 20 is provided on one side of the chamber body 18. Multiple groups of honeycomb partitions 19 are provided on the side of the interior of the chamber body 18 close to the air pump 20. The number of honeycomb partitions 19 can be 2 groups.

[0023] The adsorption head 8 pushes the fixed ring 16 to move up and down through the electric telescopic rod 17, thereby pushing the suction cup 13 and the connecting pipe 14 to move up and down. The connecting pipe 14 is adapted to the notch 7 and ensures sealing. The second solenoid valve 15 assists in the reflux of the liquid. When performing the adsorption work, through the suction force generated by the air pump 20, a seal is formed between the suction cup 13 and the surface of the tempered glass. The honeycomb partition 19 in the negative pressure chamber 10 prevents water flow from entering the air pump 20, isolates the water flow, and at the same time ensures the normal operation of the air pump 20.

[0024] A liquid level monitor 21 is provided on one side of the polishing water tank 4. A water delivery pipe group 22 for supplying liquid to the polishing water tank 4 is also provided on one side of the polishing water tank 4. An anti-overflow reflux pipe 23 communicating with the water tank 6 is provided on the other side of the polishing water tank 4.

[0025] The liquid level of the polishing water tank 4 is monitored by the liquid level monitor 21. When the liquid level of the polishing water tank 4 decreases, coolant is transported to the polishing water tank 4 through the water delivery pipe group 22. At the same time, the anti-overflow reflux pipe 23 is provided to prevent the coolant from overflowing during polishing, further increasing the practicability of the device.

[0026] The support mechanism includes a mounting plate 24 and a hydraulic cylinder 25. The mounting plate 24 is located on the front and back sides of the workbench 1, and hydraulic cylinders 25 are symmetrically provided on the mounting plate 24.

[0027] The polishing mechanism includes a rotating seat 26, a rotating shaft 27, a first adjustment chamber 28, a second adjustment chamber 29, a polishing head 30, and a feeding mechanism for loading and flipping the tempered glass. Two groups of rotating seats 26 are symmetrically provided and are respectively fixedly connected to the tops of the hydraulic cylinders 25. A first adjustment chamber 28 is rotatably installed between the two groups of rotating seats 26 through a rotating shaft 27. A first motor 31 for driving the first adjustment chamber 28 to rotate is provided on the outer wall of one group of rotating seats 26. A second adjustment chamber 29 is fixed on the first adjustment chamber 28. A polishing head 30 is provided on the second adjustment chamber 29. A longitudinal movement component for driving the polishing head 30 to move longitudinally is provided inside the second adjustment chamber 29. A feeding mechanism is provided on the first adjustment chamber 28.

[0028] In this device, the transverse movement component 44 and the longitudinal movement component have the same structure, both of which are traditional screw drive structures and will not be elaborated here in detail. The device adjusts the polishing position of the polishing head 30 through the cooperation of the transverse movement component 44 and the longitudinal movement component, thereby performing all-round polishing on the surface of the tempered glass.

[0029] One side of the grinding head 30 is provided with a liquid spraying head 32. An elastic telescopic hose 33 is arranged inside the first adjustment bin 28. A chute 34 is arranged on one side of the first adjustment bin 28. One end of the elastic telescopic hose 33 passes through the chute 34 and is connected to the liquid spraying head 32. The other end of the elastic telescopic hose 33 penetrates through the rotating shaft 27 and a set of rotating seats 26 and then communicates with a rotary joint. The other end of the rotary joint is connected to the grinding water bin 4 through a second hose 35. A water pump is arranged at the connection between the second hose 35 and the grinding water bin 4.

[0030] In this device, by arranging the liquid spraying head 32 on one side of the grinding head 30, the liquid spraying head 32 sprays water flow into the liquid in the grinding water bin 4. Through the impact force generated by the spraying, the liquid in the grinding water bin 4 generates a wave flow, thereby accelerating the heat dissipation at the grinding part of the tempered glass, and further ensuring the safety during the grinding of the tempered glass. And in this device, by arranging the elastic telescopic hose 33 inside the first adjustment bin 28, the liquid delivery of the liquid spraying head 32 is ensured while the grinding head 30 moves. The built-in structure setting not only protects the pipeline, but also ensures that the pipeline will not be affected when the grinding head 30 moves or flips.

[0031] The feeding mechanism includes a fixing plate 36, a double-headed cylinder 37, a support seat 38, a second motor 39, a connecting plate 40, a first adjustment component 41, a second adjustment component 42 and an adsorption seat 43. The fixing plate 36 is fixedly connected to the first adjustment bin 28. Two groups of horizontally arranged double-headed cylinders 37 are symmetrically arranged on the fixing plate 36. Support seats 38 are fixed at both ends of the double-headed cylinder 37. Second motors 39 are arranged on one side of the two groups of support seats 38. Two groups of connecting plates 40 are rotatably installed on the two groups of support seats 38, and the two groups of connecting plates 40 are symmetrically distributed. First adjustment components 41 are fixedly installed at the ends of the connecting plates 40. Second adjustment components 42 are installed on the two groups of first adjustment components 41. Adsorption seats 43 are symmetrically arranged on the two groups of second adjustment components 42. The first adjustment component 41 and the second adjustment component 42 cooperate to adjust the horizontal distance and the vertical distance between the four adsorption seats 43.

[0032] In this device, the first adjustment component 41 and the second adjustment component 42 have the same structure and both adopt the traditional transmission mode of a bidirectional screw, which belongs to the prior art and will not be described in detail here. In this device, the two groups of support seats 38 are supported by the double-headed cylinder 37. Separate first adjustment components 41, second adjustment components 42 and adsorption seats 43 are arranged on the two groups of support seats 38. Taking the second motor 39 as the power source, the adsorption seats 43 on the two groups of support seats 38 are respectively driven to rotate. They cooperate with each other to flip and convey the tempered glass, and then achieve the effect of automatic grinding.

[0033] Using the above-mentioned surface grinding device for tempered glass, the grinding method includes the following content; S1. Input of the conveyor belt 2 before grinding the tempered glass and output after grinding. The conveyor belt 2 sends the unground tempered glass to one side of the grinding water tank 4. The entire grinding mechanism is driven to move by the transverse movement assembly 44. At the same time, the feeding mechanism and the grinding head 30 are displaced by driving the first motor 31, so that the feeding mechanism is located below. When the feeding mechanism is above the tempered glass, the hydraulic cylinder 25 works to drive the feeding mechanism to move downward. S2. According to the size of the tempered glass, the transverse distance and longitudinal distance between the four adsorption seats 43 are adjusted through the first adjustment assembly 41 and the second adjustment assembly 42. At the same time, the hydraulic cylinder 25 continuously moves downward to drive the adsorption seats 43 to fit the surface of the tempered glass for adsorption. S3. After adsorption, the hydraulic cylinder 25 drives the tempered glass to move upward. At the same time, the transverse movement assembly 44 works synchronously to move the glass directly above the grinding water tank 4. At this time, according to the size of the tempered glass, the corresponding number of adsorption heads 8 are pushed upward by the electric telescopic rods 17, and the suction cups 13 are pushed out of the water surface. At this time, the first solenoid valve 12 and the second solenoid valve 15 are opened, so that the water in the suction cups 13 and the connecting pipes 14 flows into the water tank 6 through the return pipe 11. After that, the first solenoid valve 12 and the second solenoid valve 15 are closed. At the same time, the hydraulic cylinder 25 drives the tempered glass to move upward, and cooperates with the electric telescopic rod 17 to push the suction cup 13 to fit the bottom of the glass. At this time, the air pump 20 works to make the suction cup 13 adsorb and fix the tempered glass. S4. After the tempered glass is fixed by the suction cup 13, the first motor 31 drives the feeding mechanism and the grinding head 30 to be displaced, so that the grinding head 30 is located below. When the grinding head 30 is above the tempered glass, the hydraulic cylinder 25 works to drive the grinding head 30 to move downward, and the grinding head 30 is driven to comprehensively grind the surface of the tempered glass through the cooperation of the transverse movement assembly 44 and the longitudinal movement assembly. S5. Before grinding, the electric telescopic rod 17 drives the suction cup 13 to reset. At this time, the tempered glass is located below the liquid level. At this time, the grinding head 30 moves downward to grind the tempered glass below the liquid level. At the same time, the liquid spraying head 32 on one side of the grinding head 30 sprays liquid to the grinding position synchronously for cooling, and the sprayed water flow impacts the liquid surface, resulting in wave flow on the liquid surface, thereby accelerating the heat conduction in the water and further accelerating the heat dissipation of the grinding area. S6. After one side of the tempered glass is polished, the hydraulic cylinder 25 drives the polishing head 30 to move upward. At the same time, the first motor 31 drives the feeding mechanism to be replaced with the polishing head 30 again, and the electric telescopic rod 17 pushes the tempered glass upward. Then, the adsorption seat 43 on a set of support seats 38 adsorbs the tempered glass. Another set of support seats 38 is driven by the second motor 39 to rotate 90 degrees inward. When the support seat 38 adsorbing the tempered glass has moved upward completely, the second motor 39 on this support seat 38 drives the support seat 38 to rotate 90 degrees inward, and aligns the adsorption seats 43 on the two sets of support seats 38. At this time, through the operation of the double-headed motor, the tempered glass is moved to the adsorption seat 43 on the other set of support seats 38 and is adsorbed and fixed by the adsorption seat 43 there. Then, this set of support seats 38 works to send the tempered glass back to the polishing water tank 4, thus completing the flipping of the tempered glass. After that, the polishing work is repeated. After the polishing is completed, the polished tempered glass is sent to the conveyor belt 2 by the feeding mechanism for outward transportation.

10. A method for grinding the surface of tempered glass, which is applied to the tempered glass surface grinding device described in any one of the above claims 1-9, and is characterized in that: It includes the following steps; S1. The conveyor belt inputs the tempered glass before grinding and outputs it after grinding. The conveyor belt sends the unground tempered glass to one side of the grinding water tank. The entire grinding mechanism is driven to move by the transverse movement component. At the same time, the feeding mechanism and the grinding head are driven to change positions by the first motor, so that the feeding mechanism is located below. When the feeding mechanism is above the tempered glass, the hydraulic cylinder works to drive the feeding mechanism to move downward. S2. According to the size of the tempered glass, the horizontal distance and vertical distance between the four suction seats are adjusted by the first adjustment component and the second adjustment component. At the same time, the hydraulic cylinder continues to move downward to drive the suction seat to fit the surface of the tempered glass for adsorption. S3. After adsorption, the hydraulic cylinder drives the tempered glass to move upward. At the same time, the transverse movement component works synchronously to move the glass to directly above the grinding water tank. At this time, according to the size of the tempered glass, a certain number of suction heads are pushed upward by the electric telescopic rods to push the suction cups out of the water surface. At this time, the first solenoid valve and the second solenoid valve are opened, so that the water in the suction cups and the connecting pipes flows into the water tank through the return pipe. After that, the first solenoid valve and the second solenoid valve are closed. At the same time, the hydraulic cylinder drives the tempered glass to move upward, and cooperates with the electric telescopic rod to push the suction cup to fit the bottom of the glass. At this time, the air pump works to make the suction cup adsorb and fix the tempered glass. S4. After the tempered glass is fixed by the suction cup, the first motor drives the feeding mechanism and the grinding head to change positions, so that the grinding head is located below. When the grinding head is above the tempered glass, the hydraulic cylinder works to drive the grinding head to move downward, and the grinding head is driven to comprehensively grind the surface of the tempered glass by the transverse movement component cooperating with the longitudinal movement component. S5. Before grinding, the electric telescopic rod drives the suction cup to reset. At this time, the tempered glass is located below the liquid level. At this time, the grinding head moves downward to grind the tempered glass below the liquid level. At the same time, the liquid spraying head on one side of the grinding head sprays liquid synchronously to the grinding position for cooling, and the sprayed water flow impacts the liquid level, resulting in wave flow on the liquid level, further accelerating the heat conduction in the water and further accelerating the heat dissipation of the grinding area. S6. After one side of the tempered glass is polished, the hydraulic cylinder drives the polishing head to move upward. At the same time, the first motor drives the feeding mechanism to change positions with the polishing head again, and the electric telescopic rod pushes the tempered glass upward. Then, the adsorption head on a set of support seats adsorbs the tempered glass, and the other set of support seats rotates inward by a certain degree driven by the second motor. When the support seat adsorbing the tempered glass has moved upward completely, the second motor on this support seat drives the support seat to rotate inward by a certain degree, and aligns the adsorption seats on the two sets of support seats. At this time, through the operation of the double-headed motor, the tempered glass is moved to the adsorption seat on the other set of support seats and is adsorbed and fixed by the adsorption seat there. Then, this set of support seats operates to send the tempered glass back to the polishing water tank, thus completing the flipping of the tempered glass. After that, the polishing work is repeated. After the polishing is completed, the polished tempered glass is sent to the conveyor belt by the feeding mechanism for outward transportation.
