Description

Technical Field

[0001] This invention relates to the field of glass polishing equipment technology, and more particularly to a polishing device for tempered glass processing. Background Technology

[0002] Tempered glass, as a type of safety glass, is widely used in construction, automobiles, and home appliances. During the production of tempered glass, ordinary flat glass often has defects such as burrs and unevenness on its edges after cutting. These defects must be eliminated through a grinding process before tempering; otherwise, they will directly affect the finished quality and performance of the tempered glass. Currently, the grinding of tempered glass is usually accomplished using specialized grinding equipment. This equipment generally includes a grinding table, a grinding mechanism set on the grinding table, and a support component for supporting and positioning the glass. During grinding, the operator places the glass to be processed on the support component, and the grinding mechanism grinds the edges or surface of the glass. In existing grinding equipment, the support component is usually equipped with suction cups to fix the glass on the support table and prevent the glass from shifting during the grinding process. At the same time, the grinding equipment is also equipped with lifting and moving mechanisms to adjust the position of the grinding head in multiple directions, thereby meeting the processing needs of different grinding positions and angles.

[0003] In the grinding process of tempered glass, reliable fixation of the glass is a prerequisite for ensuring grinding accuracy and processing safety. Therefore, existing grinding devices generally use suction cups to adsorb and fix the glass from below. However, in actual use, since the installation position of the suction cup on the grinding table is usually fixed, the distribution range of its adsorption points cannot be adjusted according to the actual size of the glass. This creates a problem: when the size of the glass to be processed changes, such as switching from a large area of ​​glass to a smaller size, the fixed suction cup may not be able to effectively adsorb different parts of the glass simultaneously. For larger glass sizes, the distribution range of the suction cup's adsorption points becomes problematic. Due to the limited area, it is difficult to form a uniform adsorption force at multiple support points on the glass. This causes the glass edges or suspended parts to vibrate or shift during polishing due to uneven force. For smaller glass sizes, the bottom surface area of ​​the glass may not be sufficient to completely cover the adsorption area of ​​the suction cup holder, resulting in some suction cups failing to form an effective seal with the bottom surface of the glass, leading to air leakage. Consequently, the adsorption force is insufficient and the fixation is not secure. The existence of these problems means that existing polishing devices often require the replacement of different sizes of suction cup holders or adjustment of the suction cup layout when dealing with tempered glass of different sizes. This operation is cumbersome and time-consuming, seriously affecting processing efficiency and the consistency of polishing quality.

[0004] Therefore, how to provide a grinding device for tempered glass processing is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] The number of the slides is four sets, and the slides are respectively set on the four arms of the "cross" plate. The number and position of the suction cup body, slider and connecting cylinder match the number and position of the slides. The four sets of suction cup bodies, sliders and connecting cylinders are arranged in a ring array with the rotating disk as the array center.

[0010] The suction cup adjustment unit includes a ejector rod, the ejector rod is built in the connecting cylinder and the bottom end of the ejector rod is fixedly connected with the upper surface of the piston head. When the piston head moves upward, it will push up the tempered glass plate through the ejector rod to separate the tempered glass plate from the suction cup body.

[0011] Pressure-resistant communication pipes are fixedly connected to the sides of the four sets of connecting cylinders near the suction cup body, and the four sets of connecting cylinders and the guide through grooves form a "mouth" shape.

[0012] The push frame is movably sleeved on the surface of the bearing column, and one end of the top of the push frame far from the push cylinder is fixedly installed with a driven jacking mechanism for pressing on the top of the tempered glass plate.

[0013] The driven jacking mechanism includes a positioning ring, a rotating ring, side lugs, a support column, a spline shaft, a jacking plate, a spring member, a walking wheel, an adjustment groove, a locking bolt and a movable frame. The positioning ring is fixedly installed on the end of the top of the push frame far from the push cylinder, the rotating ring is rotatably connected in the annular groove on the positioning ring, there are two sets of side lugs, the two sets of side lugs are fixedly installed on the side of the rotating ring and distributed axisymmetrically, the support column is longitudinally and fixedly installed on the top of the side lug, the spline shaft is fixedly installed at the top end of the support column, the jacking plate is movably sleeved on the surface of the spline shaft, the jacking plate is arranged horizontally, the top end of the spline shaft is fixedly installed with a detachable top block, the spring member is movably sleeved on the surface of the spline shaft between the top block and the jacking plate, the adjustment groove is opened on the end face of the jacking plate, the movable frame is movably inserted into the interior of the adjustment groove, the locking bolt is threadedly connected to the top of the jacking plate, and the bottom end of the locking bolt passes through the jacking plate and abuts against the upper surface of the movable frame, the walking wheel is a universal wheel, and the walking wheel is rotatably installed on the lower surface of the movable frame at a position far from the jacking plate.

[0014] The top pressure plate and the movable frame form a rectangular "opening". The grinding part is movably built into the inside of a set of rectangular "openings" through a movable lifting mechanism. When the movable lifting mechanism moves the grinding part along the rectangular "opening", the top pressure plate and the movable frame are not pushed. When the grinding part does not move along the rectangular "opening", it will push the top pressure plate and the movable frame to rotate around the bearing component. The rotation of the movable frame around the bearing component will drive the traveling wheels to roll on the surface of the tempered glass plate. Thus, the top pressure plate, spline shaft, support column and side lugs drive the rotating ring to rotate inside the positioning ring. In this way, when the grinding part moves to grind the side of the tempered glass plate, the movable frame and traveling wheels will also press the grinding position of the tempered glass plate synchronously, avoiding the upward lifting of the plate due to force or the elasticity of the suction cup causing the tempered glass plate to shake.

[0015] The beneficial effects of this invention are: This invention effectively solves the technical problems of traditional tempered glass grinding devices, such as fixed and unadjustable suction cups, poor adaptability, and easy air leakage, insecure fixation, and grinding vibration deviation when processing tempered glass sheets of different specifications. This device utilizes a worm gear and worm drive structure to flexibly adjust the annular array spacing of the four suction cup bodies, adapting to tempered glass sheets of different sizes. It ensures uniform adhesion of the suction points to the bottom surface of the glass, providing a completely sealed suction process and eliminating air leakage and loosening. Simultaneously, the driven top-pressing mechanism can adaptively rotate and dynamically press against the glass grinding area, following the grinding trajectory of the workpiece. This counteracts the shaking and lifting problems caused by grinding force and the elastic deformation of the suction cups, significantly improving grinding accuracy and finished product flatness. No manual replacement or adjustment of suction cup parts is required, simplifying the processing flow and improving efficiency. The connecting pipe and U-shaped structural layout balance the air pressure of each suction cup, strengthen the overall rigidity of the equipment, effectively reduce the wear and tear on the equipment structure caused by grinding vibration, and improve the equipment's operational stability and service life.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0025] refer to Figures 1-7In this embodiment, the system includes a frame 1, a movable lifting mechanism 2, a grinding component 3, and a bearing assembly 4. The movable lifting mechanism 2 is fixedly installed on the top of the frame 1, the grinding component 3 is installed on the lower surface of the movable lifting mechanism 2, and the bearing assembly 4 is fixedly installed at the bottom of the inner wall of the frame 1. The tempered glass plate 5 is fixedly connected to the top of the bearing assembly 4 by adsorption. The bearing assembly 4 includes a bearing base 6, a bearing column 7, a suction cup adjustment unit 8, a suction cup body 9, and a "cross" plate 10. The bearing base 6 is fixedly installed at the bottom of the inner wall of the frame 1, the bearing column 7 is longitudinally fixedly installed on the top of the bearing base 6, the "cross" plate 10 is fixedly installed on the top of the bearing column 7, the suction cup adjustment unit 8 is installed on the "cross" plate 10, and the suction cup body 9 is installed on the suction cup adjustment unit 8 to adsorb the tempered glass plate 5. The bearing assembly 4 includes a slider 12, a connecting cylinder 13, a rotating shaft 21, a rotating disk 22, an arc-shaped adjustment groove 23, a worm gear 24, a worm 25, and an adjustment drive motor 26. The upper surface of the "cross" plate 10 is provided with a groove 11 that connects the top and bottom of the "cross" plate 10. The slider 12 is slidably connected inside the groove 11. The connecting cylinder 13 is fixedly installed longitudinally on the top of the slider 12. The suction cup body 9 is fixedly installed on the top of the connecting cylinder 13. The rotating shaft 21 is rotatably installed on the "cross" plate 10, and the top and bottom of the rotating shaft 21 extend to the top and bottom of the "cross" plate 10, respectively. The top of the rotating shaft 21 is fixedly connected to the lower surface of the rotating disk 22, and the bottom of the rotating shaft 21 is fixedly connected to the upper surface of the worm gear 24. The worm 25 is rotatably installed on the lower surface of the "cross" plate 10 and meshes with the worm gear 24. The arc-shaped adjustment groove 23 is opened on the surface of the rotating disk 22 to connect the top and bottom of the rotating disk 22. The spline shaft 32 is movably sleeved on the surface of the connecting cylinder 13. The adjustment drive motor 26 is fixedly installed on the inner side of the "cross" plate 10 through the connecting plate. The output shaft of the adjustment drive motor 26 is fixedly connected to one end of the worm 25.

[0026] In practical implementation, the frame 1, as the overall load-bearing base of the equipment, provides a stable installation benchmark and protective support for the top moving lifting mechanism 2 and the internal load-bearing components 4, effectively avoiding external vibrations and debris interference during the grinding operation and ensuring the stability of equipment operation. The load-bearing base 6 and the load-bearing column 7 form a vertical support structure, firmly supporting the top "cross" plate 10, ensuring the levelness and rigidity of the overall load-bearing structure, and laying the foundation for the stable placement and precise adsorption of the tempered glass plate 5. Relying on the precise meshing transmission structure of the adjustable drive motor 26, worm gear 25 and worm wheel 24, the rotating shaft 21 and rotating disk 22 can be driven to rotate synchronously. With the sliding cooperation of the slide groove 11 and the slider 12, the synchronous radial distance adjustment of the four sets of suction cup bodies 9 can be achieved. The transmission structure has a self-locking characteristic, and after adjustment, the suction cup position can be precisely locked to prevent displacement and loosening. This completely solves the defects of traditional grinding devices where the suction cup position is fixed and cannot be adapted to tempered glass plates 5 of different specifications, effectively improving the versatility of the equipment and the grinding adaptation accuracy. The frame 1, as the overall load-bearing base of the equipment, provides a stable installation benchmark and protective support for the top moving lifting mechanism 2 and the internal load-bearing components 4, effectively improving the versatility of the equipment and the grinding adaptation accuracy. The main support frame provides a stable installation base for the top moving lifting mechanism 2 and the internal load-bearing components 4. The moving lifting mechanism 2 can precisely control the lifting and moving position of the grinding parts 3 to adapt to the grinding needs of different sides of the glass. The load-bearing base 6 and the load-bearing column 7 form a stable support structure to ensure that the "cross" plate 10 is installed horizontally. Relying on the meshing transmission of the worm gear 24 and the worm 25, the synchronous spacing adjustment of the four sets of suction cup bodies 9 can be realized. The overall structure has strong linkage and high adjustment accuracy, and can effectively adapt to the fixed grinding operation of tempered glass plates 5 of different specifications.

[0027] Example 1 refer to Figures 1-7 In this embodiment, there are four sets of slide grooves 11, which are respectively set on the four arms of the "cross" plate 10. The number and position of the suction cup body 9, slider 12 and connecting cylinder 13 match the number and position of the slide grooves 11. The four sets of suction cup body 9, slider 12 and connecting cylinder 13 are arranged in a ring array with the rotating disk 22 as the array center.

[0028] In practice, the four sets of sliding grooves 11 are symmetrically arranged in a ring, allowing the four sets of suction cup bodies 9 to slide synchronously along the radial direction of the "cross" plate 10 support arm to adjust the spacing. For large-sized tempered glass plates 5, the adsorption array range can be expanded to achieve multi-point uniform adsorption and avoid the glass edge from being suspended and vibrating. For small-sized tempered glass plates 5, the adsorption spacing can be reduced to ensure that the suction cups are completely attached to the bottom surface of the glass, eliminating the problem of air leakage and instability. It can be adapted to the processing of glass of various specifications without the need to replace parts, greatly improving the adaptability of the device.

[0029] Example 2 refer to Figures 1-7In this embodiment, the suction cup adjustment unit 8 includes a piston head 14, a push rod 16, a push frame 17, a push cylinder 18, a guide groove 19, and a guide limiting block 20. The connecting cylinder 13 is a piston cylinder, and the piston head 14 is movably connected inside the connecting cylinder 13. The connecting cylinder 13 is in communication with the suction cup body 9. The push rod 16 is fixedly installed at the bottom of the piston head 14, and the bottom end of the push rod 16 extends to the bottom of the connecting cylinder 13 and the slide groove 11. The push frame 17 is fixedly installed on the bottom end of the push rod 16. The push cylinder 18 is fixedly installed on the upper surface of the bearing base 6 at the middle position. The top output shaft of the 8 is fixedly connected to the lower surface of the push frame 17. The guide groove 19 is opened on the surface of the push frame 17 at the position corresponding to the push rod 16. Each set of push rods 16 corresponds to two guide limit blocks 20. Both guide limit blocks 20 are fixedly installed on the surface of the push rod 16. One guide limit block 20 is located above the push frame 17, and the other guide limit block 20 is located below the push frame 17. When the slider 12 slides along the slide groove 11, it will drive the push rod 16 and the guide limit block 20 to move along the guide groove 19. The slide groove 11 and the guide groove 19 are arranged parallel to each other.

[0030] In practice, the cylinder 18 provides vertical power to the suction cup adjustment unit 8, which can drive the push frame 17 to rise and fall as a whole. The guide limit block 20 and the guide groove 19 are precisely matched to limit the movement, ensuring that the push rod 16 is vertically aligned without deviation during the lifting process. At the same time, it can be adapted to the horizontal sliding adjustment stroke of the slider 12, so as to achieve the mutual non-interference between horizontal distance adjustment and vertical adsorption adjustment, effectively ensuring that the piston head 14 moves smoothly inside the connecting cylinder 13, and improving the accuracy and stability of the adsorption and depressurization action of the suction cup body 9.

[0031] Example 3 refer to Figures 1-7 In this embodiment, the suction cup adjustment unit 8 includes a push rod 15, which is built into the connecting cylinder 13 and the bottom end of the push rod 15 is fixedly connected to the upper surface of the piston head 14. When the piston head 14 moves upward, it will lift the tempered glass plate 5 through the push rod 15 to separate the tempered glass plate 5 from the suction cup body 9.

[0032] In practice, the push rod 15 and the piston head 14 work together. After grinding, the piston head 14 moves upward and drives the push rod 15 to push out synchronously, quickly separating the tempered glass plate 5 from the suction cup body 9. This replaces the traditional manual method of removing glass, effectively avoiding the problems of glass edge damage and scratches caused by hard peeling. At the same time, the automated unloading structure simplifies the operation process, shortens the waiting time for material replacement, and effectively improves the overall efficiency of glass grinding and processing.

[0033] Example 4 refer to Figures 1-7, in this embodiment, pressure-resistant communication tubes 39 are fixedly connected to the sides of the four sets of the connecting cylinders 13 at positions close to the suction cup bodies 9, and the four sets of connecting cylinders 13 and the guide through grooves 19 form a "mouth"-shaped structure.

[0034] In specific implementation, the communication tubes 39 can realize intercommunication and equalization of the internal air pressure of the four sets of connecting cylinders 13, ensure uniform and consistent adsorption force of the four sets of suction cup bodies 9, and avoid fixation offset caused by insufficient air pressure of a single set of suction cups. Meanwhile, the communication tubes 39 have pressure resistance, can resist grinding vibration and external force extrusion, and prevent pipeline deformation and air leakage. The "mouth"-shaped symmetrical structure greatly improves the overall structural rigidity of the bearing assembly 4, reduces the probability of equipment operation deformation, and ensures long-term operation stability.

[0035] Embodiment 5 Reference Figures 1-7In this embodiment, the push frame 17 is movably sleeved on the surface of the support column 7. A driven pressing mechanism 27 for pressing against the top of the tempered glass plate 5 is fixedly installed at the top end of the push frame 17 away from the push cylinder 18. The driven pressing mechanism 27 includes a positioning ring 28, a rotating ring 29, a side lug 30, a support column 31, a spline shaft 32, a pressing plate 33, a spring 34, a traveling wheel 35, an adjusting groove 36, a locking bolt 37, and a movable frame 38. The positioning ring 28 is fixedly installed on the top end of the push frame 17 away from the push cylinder 18, and the rotating ring 29 is rotatably connected to the positioning ring 28. Within the annular groove, there are two sets of side ears 30, which are fixedly installed on the side of the rotating ring 29 and distributed symmetrically. A support column 31 is longitudinally fixedly installed on the top of the side ears 30. A spline shaft 32 is fixedly installed on the top of the support column 31. A top pressure plate 33 is movably sleeved on the surface of the spline shaft 32. The top pressure plate 33 is horizontally positioned. A detachable top block is fixedly installed on the top of the spline shaft 32. A spring 34 is movably sleeved on the surface of the spline shaft 32, located between the top block and the top pressure plate 33. An adjusting groove 36 is formed on the end face of the top pressure plate 33. A movable frame 38 is movably inserted into the adjusting groove 36. The locking bolt 37 is threadedly connected to the top of the top pressure plate 33, and the bottom end of the locking bolt 37 passes through the top pressure plate 33 and abuts against the upper surface of the movable frame 38. The traveling wheel 35 is a universal wheel, and the traveling wheel 35 is rotatably mounted on the lower surface of the movable frame 38 away from the top pressure plate 33. The top pressure plate 33 and the movable frame 38 form a rectangular "opening". The grinding part 3 is movably built into a set of rectangular "openings" through the moving lifting mechanism 2. When the moving lifting mechanism 2 drives the grinding part 3 to move along the rectangular "openings", the top pressure plate 33 and the movable frame 38 are not pushed. When the grinding part 3 does not move along the rectangular "opening", it will push the top pressure plate 33 and the movable frame 38 to rotate around the bearing assembly 4. The rotation of the movable frame 38 around the bearing assembly 4 will drive the traveling wheel 35 to roll on the surface of the tempered glass plate 5. Thus, the top pressure plate 33, spline shaft 32, support column 31 and side lug 30 will drive the rotating ring 29 to rotate inside the positioning ring 28. In this way, when the grinding part 3 moves to grind the side of the tempered glass plate 5, the movable frame 38 and the traveling wheel 35 will press the grinding position of the tempered glass plate 5 synchronously, avoiding the upward lifting caused by the force or the elasticity of the suction cup causing the tempered glass plate 5 to shake.

[0036] In practice, the driven pressure mechanism 27 achieves passive adaptive rotation based on the working trajectory of the grinding component 3, without the need for additional power drive. The traveling wheel 35 rolls and fits the glass surface without jamming or scratches. The spring component 34 can provide elastic buffer pressure, which can not only ensure the pressing limit of the grinding area, but also avoid the rigid pressure damaging the glass surface. The locking bolt 37 can flexibly adjust the extension length of the movable frame 38 to adapt to the pressure requirements of different glass widths. The dynamic pressure stabilization and limit throughout the process completely solves the problems of shaking and warping deformation during glass grinding.

[0037] The working principle of this invention is: During equipment operation, the operator places the tempered glass plate 5 to be processed on top of the four sets of suction cup bodies 9, starts the adjustment drive motor 26 to drive the worm gear 25 to rotate, meshes with the drive worm wheel 24, the rotating shaft 21 and the rotating disk 22 to rotate synchronously. The rotation of the rotating disk 22 drives the connecting cylinder 13 to move through the arc-shaped adjustment groove 23. The movement of the connecting cylinder 13 is achieved by the slider 12 sliding radially along the groove 11 of the "cross" plate 10, precisely adjusting the annular array spacing of the four sets of suction cup bodies 9 to accommodate tempered glass plates 5 of different sizes. This allows for flexible adaptation to the processing of glass of various specifications, thus solving the problem of suction leakage caused by the fixed suction cups and inability to adapt to different sizes in traditional devices. Issues with air pressure and insecure fixing; after the spacing is adjusted, a negative pressure is formed inside the connecting cylinder 13, which adsorbs and fixes the tempered glass plate 5 through the suction cup body 9. During the grinding operation, the moving lifting mechanism 2 drives the grinding part 3 to move along the side of the glass for grinding. The moving lifting mechanism 2 is an existing technology device used to drive the horizontal movement and lifting of the grinding part 3. When the grinding part 3 deviates from the opening track, it will push the top pressure plate 33 and the movable frame 38 to rotate adaptively, driving the traveling wheel 35 to roll on the glass surface and continuously press the grinding area. This can offset the grinding impact force and the elastic deformation of the suction cup in real time, thereby preventing the glass from shaking or tilting, and greatly improving the grinding accuracy; processing completed. Afterwards, a top limiting plate is fixedly installed on the surface of the spline shaft 32 below the top pressure plate 33. When the cylinder 18 drives the piston head 14 upward, it also drives the push frame 17 to move upward synchronously. Thus, when the support column 31 moves upward with the push frame 17, it synchronously drives the spline shaft 32 upward. The upward movement of the spline shaft 32 drives the top limiting plate upward, causing the top pressure plate 33 to slowly move upward, releasing the pressure on the tempered glass plate 5. When the top pressure plate 33 is pushed downward by the spring 34 and limited by the top limiting plate, the top pressure plate 33 no longer moves downward and moves upward synchronously with the spline shaft 32. This causes the top pressure plate 33 to move upward. The movable frame 38 moves upward, thereby driving the traveling wheel 35 away from the tempered glass plate 5. At this time, the pushing frame 17 moves upward and simultaneously drives the pushing rod 16 upward through the guide limit plate 20. The upward movement of the pushing rod 16 drives the top rod 15 upward through the piston 14. After the traveling wheel 35 moves away from the tempered glass plate 5, the top rod 15 moves upward and lifts the tempered glass plate 5, thereby separating it from the suction cup body 9, making it easy to remove the tempered glass plate 5. The top rod 15 lifts the glass to achieve automatic unloading, simplifying the operation process. The connecting pipe 39 balances the air pressure of each group of suction cups to ensure uniform adsorption force, making the equipment more stable and durable.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
