Description

Technical Field

[0001] This invention relates to the field of curved glass edge grinding technology, and more specifically to an edge grinding device for curved glass before tempering. Background Technology

[0002] Curved glass refers to glass with a certain curvature processed onto the surface of flat glass. Edge grinding before tempering curved glass enters the tempering furnace is to improve the yield rate of the tempered glass. This is because during the initial cutting process, small cracks are left around the edges of the curved glass. Although these cracks are not easily visible to the naked eye, if they are not treated before being sent to the tempering furnace, they can lead to edge chipping and breakage. During the heating and cooling process, the cracks and defects at the edges of unground curved glass can cause furnace explosions under the influence of various or uneven stresses, resulting in significant equipment damage and even personal injury.

[0003] In existing technologies, when using an edge grinding device to grind the edges of curved glass, although spraying water onto the area between the grinding block and the curved glass can prevent dust generated during edge grinding from scattering and affecting the air quality of the working environment, the grinding debris still splashes into the device along with the wastewater. This requires workers to spend a considerable amount of time cleaning and collecting the debris after using the device, increasing their workload and indirectly reducing the efficiency of the device in grinding curved glass. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an edge grinding device for tempering curved glass.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] Optionally, the drive mechanism includes second electric telescopic rods installed on the outer walls of both sides of the housing. The telescopic ends of the two second electric telescopic rods are connected to a first horizontal plate. A second sliding groove is provided at the bottom of the first horizontal plate, and a first lead screw is installed inside the second sliding groove.

[0010] Optionally, a second slider is installed on the outer wall of the first lead screw, a second horizontal plate is installed at the bottom of the second slider, a third groove is opened at the bottom of the second horizontal plate, a second lead screw is installed inside the third groove, a third slider is installed on the outer wall of the second lead screw, and a rectangular plate is connected to the bottom of the third slider through a connecting rod. Both outer walls of the rectangular plate are provided with protective mechanisms.

[0011] Optionally, a first motor is installed at the bottom of the rectangular plate, the output end of the first motor is connected to the top of the grinding block, and two water outlet pipes with their bottom ends facing the grinding block are installed at the top of the rectangular plate. The top ends of the two water outlet pipes are connected to the output end of an external water outlet mechanism through flexible hoses.

[0012] Optionally, the protective mechanism includes rotating blocks rotatably mounted at both ends of the rectangular plate. The ends of the two rotating blocks that are far apart are each connected to a mounting base via a third electric telescopic rod. Both mounting bases are equipped with take-up rollers, and the outer walls of both take-up rollers are covered with protective cloth. Telescopic curtains are installed at the bottom of the other two ends of the rectangular plate.

[0013] Optionally, a fixing block is installed at the center of the inner bottom surface of the housing, a connecting block is installed on the top of the fixing block, a locking block is installed at the end of each of the two protective cloths away from the winding roller, the outer walls on both sides of the connecting block are provided with locking grooves that are compatible with the locking blocks, the ends of each of the two protective cloths near the locking blocks are provided with openings that are compatible with the outer wall of the vacuum suction cup, and elastic fabric is provided near the openings of the protective cloths.

[0014] Optionally, the connecting block has multiple second motors installed inside, each of the output ends of the multiple second motors has a first rotating plate installed, and each of the multiple first rotating plates has a second rotating plate installed at the end away from the second motor via a rotating shaft, and each of the multiple second rotating plates has an auxiliary suction cup installed at its bottom end.

[0015] Optionally, two fourth electric telescopic rods are installed inside the fixing block, and a circular groove adapted to the telescopic rods of the two fourth electric telescopic rods is opened at the bottom of the connecting block. Two telescopic limiting rods are symmetrically installed at the bottom of the connecting block, and a limiting groove adapted to the telescopic end of the telescopic limiting rod is opened on the outer wall of the telescopic end of the two fourth electric telescopic rods.

[0016] The beneficial effects of this invention are:

[0017] 1. In this invention, after the curved glass is adsorbed and fixed by multiple vacuum suction cups, the telescopic curtains at both ends of the rectangular plate are controlled to unfold downwards, which can block the splashing of wastewater and debris generated by the grinding block during the edge grinding of the curved glass. The protective cloths located at the other two ends of the rectangular plate can protect the other two sides, and can filter the wastewater and debris blocked by the two telescopic curtains, leaving the debris on the inner wall of the two protective cloths, thereby achieving the effect of automatically filtering and collecting edge grinding debris, eliminating the need for subsequent personnel to treat the debris and wastewater inside the box.

[0018] 2. In this invention, after the curved glass is placed on top of multiple vacuum suction cups, two rotating blocks are controlled to drive two take-up rollers to rotate downwards together, so that the two take-up rollers can press down on the curved glass on top of multiple vacuum suction cups, making the curved glass adhere more tightly to the multiple vacuum suction cups; and since the protective cloth rolled on the surface of the take-up rollers is made of soft material, it can prevent the curved glass from being pressed and broken when the take-up rollers come into contact with the curved glass.

[0019] 3. In this invention, if the curved glass breaks during the grinding process of the grinding block, the two protective cloths in the unfolded state can block and collect these fragments. By extending the extension ends of the two second electric telescopic rods upward, the two protective cloths are moved out from the outer wall of the corresponding two vacuum suction cups, and the connecting block is pulled upward together, moving the fragments collected on the inner wall of the two protective cloths upward together. The rotation of the second screw drives the third slider and multiple parts at the bottom to move to the outside of the box for cleaning, avoiding the fragments falling downward and damaging the air pipe of the vacuum suction cup, and preventing the problem of subsequent manual cleaning of the fragments.

[0020] 4. In this invention, after the device has completed the edge grinding process on the curved glass and the staff has cleaned and maintained the components inside the device, the two take-up rollers are controlled to rotate, causing the two protective cloths to extend. The telescopic ends of the two second electric telescopic rods are also controlled to extend upwards a certain distance. Then, the two rotating blocks are controlled to drive the two take-up rollers to rotate upwards together to a vertical position. At this time, the two protective cloths can be simultaneously placed on the top of the two vacuum suction cups to protect the multiple vacuum suction cups and prevent external dust or other debris from falling into the vacuum suction cups when the device is not in use, thus affecting the subsequent use of the vacuum suction cups.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figures 1-9A device for edge grinding of curved glass before tempering includes a housing 1. Two fixed plates 4 are installed on one outer wall of the housing 1. A movable plate 2 is installed on the top of the two fixed plates 4. A conveyor belt 3 is installed inside the movable plate 2. Multiple vacuum suction cups 9 for fixing the curved glass are installed on the inner bottom surface of the housing 1. A grinding block 23 is provided on the top of the multiple vacuum suction cups 9. A drive mechanism for moving the grinding block 23 is installed on the top of the housing 1. A push plate 10 for quickly removing the curved glass is installed on the side of the housing 1 parallel to the conveyor belt 3.

[0034] As a technical optimization of the present invention, each of the two fixed plates 4 has a first sliding groove 12 on its top, and a first slider 19 is installed inside each of the two first sliding grooves 12. The two first sliders 19 are connected to the bottom of the moving plate 2. A mounting plate 17 is installed on the top of the end of the moving plate 2 near the housing 1, and two sets of air outlets 18 are symmetrically installed on the bottom of the mounting plate 17. A first linear motor is pre-installed inside each of the two first sliding grooves 12. The two first linear motors can drive the two first sliders 19 to move back and forth in the first sliding grooves 12, thereby driving the moving plate 2 to move back and forth on the top of the two fixed plates 4. The two sets of air outlets 18 are connected to the output end of an external blower through connecting pipes, so that the two sets of air outlets 18 can blow air to the curved glass surface placed on top of the conveyor belt 3.

[0035] As a technical optimization of the present invention, two first electric telescopic rods 11 are installed on one side of the outer wall of the box body 1, and the telescopic ends of the two first electric telescopic rods 11 are connected to the push plate 10.

[0036] As a technical optimization of the present invention, the driving mechanism includes second electric telescopic rods 5 installed on the outer walls of both sides of the housing 1. The telescopic ends of the two second electric telescopic rods 5 are connected to a first horizontal plate 6. A second sliding groove is provided at the bottom of the first horizontal plate 6, and a first lead screw 20 is installed inside the second sliding groove. In actual use, a first servo motor is installed at one end of the first horizontal plate 6, and the output end of the first servo motor is connected to one end of the first lead screw 20, thereby driving the first lead screw 20 to rotate forward and backward within the second sliding groove.

[0037] As a technical optimization of the present invention, a second slider is installed on the outer wall of the first lead screw 20, and a second horizontal plate 7 is installed at the bottom end of the second slider. A third groove is formed at the bottom of the second horizontal plate 7, and a second lead screw 21 is installed inside the third groove. A third slider 22 is installed on the outer wall of the second lead screw 21, and a rectangular plate 8 is connected to the bottom end of the third slider 22 via a connecting rod. Protective mechanisms are provided on both outer walls of the rectangular plate 8. In actual use, a second servo motor is installed at one end of the second horizontal plate 7, and the output end of the second servo motor is connected to one end of the second lead screw 21, thereby driving the second lead screw 21 to rotate forward and backward within the third groove.

[0038] As a technical optimization of the present invention, a first motor is installed at the bottom of the rectangular plate 8. The output end of the first motor is connected to the top of the grinding block 23. Two water outlet pipes 28 with their bottom ends facing the grinding block 23 are installed at the top of the rectangular plate 8. The top ends of the two water outlet pipes 28 are connected to the output end of an external water outlet mechanism through flexible hoses. After the first motor is started, it can drive the grinding block 23 to rotate, thereby grinding the edge of the curved glass. During the rotation of the grinding block 23, the external water outlet mechanism delivers water to the inside of the water outlet pipes 28 through flexible hoses, and discharges the water to the surface of the grinding block 23 through the bottom end of the water outlet pipes 28, preventing grinding dust from overflowing.

[0039] As a technical optimization of the present invention, the protective mechanism includes rotating blocks 27 rotatably installed at both ends of the rectangular plate 8. The ends of the two rotating blocks 27 that are far apart are connected to mounting seats 25 through a third electric telescopic rod 26. The interior of the two mounting seats 25 is equipped with winding rollers 14. The outer walls of the two winding rollers 14 are wound with protective cloth 13. The bottom of the other two ends of the rectangular plate 8 are equipped with telescopic curtains 30. In actual use, a third servo motor is installed at one end of the rectangular plate 8. The output ends of the two third servo motors are respectively connected to the rotating parts of the rotating block 27 and the rectangular plate 8, thereby driving the rotating block 27 to rotate. A fourth servo motor is installed at one end of each of the two mounting seats 25. The output ends of the two fourth servo motors are respectively connected to the two take-up rollers 14 and the rotating parts of the mounting seats 25, thereby driving the take-up rollers 14 to rotate inside the mounting seats 25 to take up and unfold the protective cloth 13. The telescopic curtain 30 is electrically driven and can be controlled by an external power source to extend and retract downwards. Furthermore, auxiliary shielding curtains are pre-installed on the outer wall of each rotating block 27 near the mounting seat 25. One end of the auxiliary shielding curtain is connected to the mounting seat 25. During the movement of the mounting seat 25 by the two third electric telescopic rods 26, the auxiliary shielding curtain can be synchronously extended and retracted, so that the auxiliary shielding curtain can block the gap between the mounting seat 25 and the rotating block 27, preventing wastewater and debris from overflowing from above.

[0040] As a technical optimization of the present invention, a fixing block 15 is installed in the center of the inner bottom surface of the housing 1, and a connecting block 16 is installed on the top of the fixing block 15. Each of the two protective fabrics 13 has a locking block 29 installed at the end away from the winding roller 14. The outer walls of both sides of the connecting block 16 have slots 34 that fit the locking blocks 29. Each of the two protective fabrics 13 has an opening 24 near the locking blocks 29 that fits the outer wall of the vacuum suction cup 9. Elastic fabric is provided on the part of the protective fabric 13 near the opening 24. After the locking blocks 29 are connected to the slots 34, one end of the protective fabric 13 can be connected and fixed to the connecting block 16. Before the protective fabric 13 is connected to the connecting block 16, the opening 24 of the protective fabric 13 is fitted onto the surface of the vacuum suction cup 9 to avoid affecting the use of the vacuum suction cup 9. When the protective fabric 13 is removed from the surface of the vacuum suction cup 9, the diameter of the opening 24 automatically shrinks due to the contraction of the elastic fabric.

[0041] As a technical optimization of the present invention, multiple second motors 35 are installed inside the connecting block 16. Each output end of the multiple second motors 35 is equipped with a first rotating plate 31. The ends of the multiple first rotating plates 31 furthest from the second motors 35 are each equipped with a second rotating plate 32 via a rotating shaft. The bottom ends of the multiple second rotating plates 32 are each equipped with an auxiliary suction cup 33. The multiple second motors 35 can drive the multiple first rotating plates 31 to rotate, allowing the first rotating plates 31 to extend or retract from the connecting block 16. A fifth servo motor is pre-installed inside the ends of the multiple first rotating plates 31 furthest from the second motors 35. The output ends of these fifth servo motors are connected to the rotating shaft, thereby driving the second rotating plates 32 to rotate synchronously. The auxiliary suction cup 33 is also a vacuum suction cup, which can be driven by an externally pre-installed vacuum device.

[0042] As a technical optimization of the present invention, two fourth electric telescopic rods 37 are installed inside the fixing block 15. The bottom of the connecting block 16 has a circular groove adapted to the telescopic rods of the two fourth electric telescopic rods 37. Two telescopic limiting rods 36 are symmetrically installed at the bottom of the connecting block 16. The outer walls of the telescopic ends of the two fourth electric telescopic rods 37 each have limiting grooves 38 adapted to the telescopic ends of the telescopic limiting rods 36. The connecting block 16 can be moved upwards by extending the telescopic ends of the two fourth electric telescopic rods 37. When the telescopic ends of the two telescopic limiting rods 36 move out of the limiting grooves 38, the connection between the connecting block 16 and the fixing block 15 is lost, and the connecting block 16 can be detached from the top of the fixing block 15.

[0043] In this invention, when the user uses the device, the curved glass to be edged is placed on top of the conveyor belt 3. The two first sliders 19 drive the moving plate 2 towards the vacuum suction cups 9 until the conveyor belt 3 moves close to the vacuum suction cups 9. When the conveyor belt 3 transports the curved glass to the top of the multiple vacuum suction cups 9, please refer to... Figure 5 As shown, the air outlet 18 on the right side is controlled to discharge air to clean the dust on the surface of the curved glass. After the curved glass is moved to the top of multiple vacuum suction cups 9, it can be attached and fixed to the smooth outer wall of the curved glass by the multiple vacuum suction cups 9. Finally, the telescopic ends of the two second electric telescopic rods 5 are retracted downwards, causing the grinding block 23 to come into contact with the edge of the curved glass. The first motor drives the grinding block 23 to rotate, thereby grinding the edge of the curved glass. The water discharged from the bottom of the two water pipes 28 can absorb the dust generated during the grinding, preventing dust from polluting the working environment.

[0044] After the curved glass is edge-ground, multiple first rotating plates 31 and second rotating plates 32 can be rotated by multiple second motors 35. Figure 8 After reaching the indicated state, control the multiple second rotating plates 32 to rotate 180 degrees, causing the multiple auxiliary suction cups 33 to rotate to the top. After the multiple vacuum suction cups 9 release their adsorption on the curved glass, the extension of the telescopic ends of the two fourth electric telescopic rods 37 drives the multiple auxiliary suction cups 33 to move upward, pushing the curved glass to a position away from the vacuum suction cups 9. The two first electric telescopic rods 11 drive the push plate 10 to move, pushing the curved glass on top of the multiple auxiliary suction cups 33 to the top of the conveyor belt 3. At this time, as shown... Figure 5 As shown, a set of air outlets 18 on the bottom left of the control mounting plate 17 discharges air to clean the debris and moisture from the surface of the curved glass. After the curved glass moves to the top of the conveyor belt 3, the reverse rotation of the conveyor belt 3 will move the curved glass to a position away from the box 1 and remove it.

[0045] Before placing the curved glass on top of the multiple vacuum suction cups 9, the two take-up rollers 14 can be controlled to rotate, causing the two protective cloths 13 to unfold downwards by a certain length. The two openings 24 at the ends of the two protective cloths 13 away from the take-up rollers 14 are then respectively fitted onto the surfaces of the two corresponding vacuum suction cups 9. Then, the locking blocks 29 at the ends of the two protective cloths 13 away from the take-up rollers 14 are respectively inserted into the corresponding slots 34, so that the two protective cloths 13 are now located on both sides of the multiple vacuum suction cups 9. Figure 3 As shown; then, after the telescopic ends of the two first electric telescopic rods 11 are extended to a specified length, the push plate 10 is driven to move a distance closer to the multiple vacuum suction cups 9. When the conveyor belt 3 transports the curved glass to the top of the multiple vacuum suction cups 9, the push plate 10 located on one side of two of the vacuum suction cups 9 can limit one end of the curved glass, so that the curved glass is in the same position when it is placed on the top of the multiple vacuum suction cups 9, ensuring that the subsequent grinding block 23 accurately grinds the edge of the curved glass.

[0046] After the curved glass is placed on top of multiple vacuum suction cups 9, the two take-up rollers 14 can be controlled to rotate again, increasing the length of the two protective cloths 13. Then, the two rotating blocks 27 are controlled to drive the two take-up rollers 14 to rotate downwards together, so that the two take-up rollers 14 can press the curved glass on top of the multiple vacuum suction cups 9 downwards, making the curved glass adhere more tightly to the multiple vacuum suction cups 9. Moreover, since the protective cloth 13 rolled on the surface of the take-up rollers 14 is a soft material, it can prevent the curved glass from being crushed when the take-up rollers 14 come into contact with the curved glass.

[0047] After the curved glass is adsorbed and fixed by multiple vacuum suction cups 9, the telescopic curtains 30 at both ends of the control rectangular plate 8 are unfolded downwards, which can block the splashing of wastewater and debris generated by the grinding block 23 during the edge grinding of the curved glass. The protective cloths 13 located at the other two ends of the rectangular plate 8 can protect the other two sides and filter the wastewater and debris blocked by the two telescopic curtains 30, leaving the debris on the inner wall of the two protective cloths 13, and discharging the filtered wastewater into the interior of the box 1, thereby achieving the effect of automatically filtering and collecting edge grinding debris, eliminating the need for subsequent personnel to treat the debris and wastewater inside the box 1.

[0048] If, during the grinding process of the grinding block 23, uneven force is applied to the curved glass, causing the curved glass to shatter, the glass fragments will fall downwards. At this time, the two unfolded protective cloths 13 can collect and block these fragments. The two fourth electric telescopic rods 37 are then controlled to extend upwards, causing the connecting block 16 to move upwards as well. Next, the telescopic ends of the two telescopic limit rods 36 are controlled to move out of the limit grooves 38 at the telescopic ends of the fourth electric telescopic rods 37, thus disengaging the connection between the connecting block 16 and the fixed block 15. Then, the upward extension of the two second electric telescopic rods 5 causes components such as the rectangular plate 8 to move upwards, causing the two protective cloths 13 to move out of the outer walls of the corresponding two vacuum suction cups 9, and pulling the connecting block 16 upwards as well. The two protective cloths 13 are moved upwards together, collecting the fragments inside. After the two protective cloths 13 are removed, the workers can use thin ropes or other tools to tie them tightly at the bottom of the multiple openings 24, thus sealing the openings 24 and preventing glass fragments from falling downwards. Then, the second lead screw 21 is rotated to move the third slider 22 and multiple parts at the bottom together, thereby moving the two protective cloths 13 and the fragments inside them to the outside of the box 1. After the workers release the connection between the clips 29 and the slots 34 of the two protective cloths 13, the fragments can be discharged to the outside of the box 1, preventing the fragments from falling downwards and damaging the air tube of the vacuum suction cup 9, and avoiding the need for a lot of manual time to clean up the fragments later.

[0049] Meanwhile, after the curved glass breaks, a small number of fragments fall into the vacuum suction cup 9, affecting its airtightness and preventing it from stably adsorbing and fixing the curved glass. To avoid affecting the subsequent edge grinding work on the curved glass, the operator can place circular partitions on top of multiple empty suction cups 9 to protect them and prevent wastewater and debris from entering the vacuum suction cups 9, thus increasing the difficulty of debris cleaning. Then, the multiple first rotating plates 31 can be controlled to rotate... Figure 8 After reaching the indicated state, control the multiple second rotating plates 32 to rotate 180 degrees, driving the multiple auxiliary suction cups 33 to rotate to the top. At this time, the multiple auxiliary suction cups 33 located at the top are higher than the connecting block 16, and can be extended upwards through the extension ends of the two fourth electric telescopic rods 37, driving the multiple auxiliary suction cups 33 to move to the same height as the vacuum suction cup 9. Then, the multiple auxiliary suction cups 33 continue to adsorb and fix the curved glass that needs to be edged. After the subsequent edge grinding work of the curved glass is completed, the staff will clean the glass debris inside the multiple vacuum suction cups 9 to avoid affecting the subsequent edge grinding work of the curved glass.

[0050] If the first electric telescopic rod 11 malfunctions during use and cannot continue to drive the push plate 10 to push the edged curved glass to the top of the conveyor belt 3, the above-mentioned method of handling glass fragments can be used. By extending the telescopic ends of the two second electric telescopic rods 5 upwards, the two protective cloths 13 and the connecting block 16 are moved upwards to remove the edged curved glass. Then, the curved glass wrapped by the two protective cloths 13 can be manually picked up and placed. In addition, during the upward and horizontal movement of the curved glass, the two relatively soft protective cloths 13 are used to fix the two sides of the curved glass, which can protect the curved glass and prevent the edges and corners of the curved glass from being bumped and damaged during the process of picking up the curved glass.

[0051] After the device completes the edge grinding process on the curved glass and the staff cleans and maintains the internal components, the two protective cloths can be kept in a 13-inch position. Figure 3 In the state shown, the two take-up rollers 14 are controlled to rotate, causing the two protective cloths 13 to extend. After the telescopic ends of the two second electric telescopic rods 5 extend upward a certain distance, the two rotating blocks 27 are controlled to drive the two take-up rollers 14 to rotate upward 90 degrees to a vertical position. At this time, the two protective cloths 13 can be synchronously driven to cover the top of the two vacuum suction cups 9 respectively, protecting the multiple vacuum suction cups 9 and preventing external dust or other debris from falling into the interior of the vacuum suction cups 9 when the device is not in use, thus affecting the subsequent use of the vacuum suction cups 9.
