Description

Technical Field

[0001] This utility model relates to a glass processing equipment, and more particularly to a glass grinding device. Background Technology

[0002] Tempered glass is a type of safety glass. Tempered glass is actually a prestressed glass. To improve the strength of the glass, chemical or physical methods are usually used to create compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the load-bearing capacity and enhancing the glass's resistance to wind pressure, temperature changes, and impact.

[0003] In the existing technology, due to the physical properties of tempered glass, it is easily damaged by improperly controlled pressure. If the surface defects of tempered glass are repaired by manual polishing, it is impossible to accurately quantify the applied pressure, which can easily lead to the destruction of the local compressive stress layer due to uneven force or instantaneous overload.

[0004] Therefore, this invention aims to provide a polishing device for glass processing, which solves the technical problem in the prior art that tempered glass is easily damaged by improperly controlled pressure due to its physical properties, and that relying on manual polishing to repair surface defects makes it impossible to accurately quantify the applied pressure.

The ends of the two winding ropes 726 away from the winding wheel 725 are fixedly connected to the upper end face of the mounting frame 708.

[0038] Reference Figure 1 , Figure 6 and Figure 7 The sliding seat 702 has two mounting slots, and a fixing member 729 is fixedly connected in each of the two mounting slots. A guide wheel 730 is rotatably connected to each of the two fixing members 729. The two winding ropes 726 slide outside the corresponding guide wheel 730. A connecting seat 727 is fixedly connected to the upper end face of the winding wheel 725. The connecting seat 727 has a toothed groove 728.

[0039] Reference Figure 1 , Figure 6 and Figure 7 A mounting bracket 719 is fixedly connected to the top of the sliding seat 702. An electric telescopic rod 720 is fixedly connected to the mounting bracket 719. An installation kit 721 is fixedly connected to the drive end of the electric telescopic rod 720. A stepper motor 722 is fixedly connected to the inner side wall of the installation kit 721. A gear component 723 is fixedly connected to the output end of the stepper motor 722. The gear component 723 is located directly above the tooth groove 728. Two mutually symmetrical fixing brackets 712 are fixedly connected to the upper end face of the sliding seat 702. Both fixing brackets 712 have movable holes. A threaded rod 713 is rotatably connected to both movable holes. A gear component 715 is fixedly connected to the outer wall of the two threaded rods 713 that are close to each other. The teeth of the two gear components 715 can mesh with the gear component 723.

[0040] Reference Figure 1 and Figure 6 Both fixed brackets 712 have round holes, and fixed rods 714 are fixedly connected to both round holes. Both threaded rods 713 have sliding members 716 connected to their exteriors by threads. Both sliding members 716 slide outside the corresponding fixed rods 714. Both sliding members 716 have through holes at their lower ends, and connecting rods 717 are fixedly connected to both through holes. Both connecting rods 717 have fixed contact blocks 718 fixedly connected to their ends near the movable frame 3.

[0041] In specific application scenarios, before surface treatment, the electric telescopic rod 720 pushes the gear component 723 down until it engages with the tooth groove 728. At this time, the stepper motor 722 is started, which drives the winding wheel 725 to rotate through the tooth groove 728 and the connecting seat 727. The winding wheel 725 tightens the winding rope 726, pulling the mounting frame 708 to slide upward along the fixed vertical rod 707 against the elastic force of the telescopic spring 710. After the tempered glass is positioned and fixed, the location of the scratches and defects coated with ultra-fine polishing paste is observed through the vision camera 706. The drive motor 11 is started to drive the threaded... Rotating rod 10 drives the sliding table 9 and movable frame 3 to slide. Simultaneously, servo motor 704 starts, driving transmission gear 705 to rotate. Through the meshing of transmission gear 705 and transmission rack 701, sliding seat 702 is driven to slide, causing felt polishing wheel 703 to move above the defect. At this time, electric telescopic rod 720 retracts, causing gear 723 to mesh with gear 715 on both sides, driving threaded rod 713 to rotate. This drives sliding member 716 to slide along fixed rod 714, causing connecting rod 717 to drive fixed contact block 718 to press tightly against the side wall of movable frame 3, fixing sliding seat 702. To prevent positional shifts during polishing, the electric telescopic rod 720 re-engages the gear component 723 into the tooth groove 728. The stepper motor 722 drives the take-up wheel 725 to rotate in the opposite direction, releasing the take-up rope 726. The telescopic spring 710 elastically returns to its original position, pushing the mounting frame 708 down to lower its height, ensuring the felt polishing wheel 703 is in close contact with the upper surface of the tempered glass. The polishing motor 711 then starts, driving the felt polishing wheel 703 to rotate at low speed, repairing and polishing imperfections on the tempered glass surface. This is achieved through the alternating support of the hydraulic lifting conveyor belt and the flexible rotating roller. The device not only transports the tempered glass but also ensures the bottom support force of the tempered glass during the polishing and repair process. By locking the pressure control mechanism and the position of the polishing components, it prevents the position from shifting due to the reaction force generated during polishing, thus ensuring the reliability and accuracy of the operation. Furthermore, by adjusting the traction force of the winding rope on the polishing components, the felt polishing wheel 703 adapts to the surface of tempered glass of different thicknesses by relying on its elastic restoring force, achieving low-pressure contact with the tempered glass. This eliminates the risk of instantaneous overload caused by manual pressing, reduces the uncertainty of human operation, and ensures the safety and high adaptability of the device.

[0042] Reference Figure 1 , Figure 2 and Figure 3 A drive motor 11 is fixedly connected to one side of the inner wall of the workbench 2. The output end of the drive motor 11 is fixedly connected to one end of the threaded rod 10. Multiple hydraulic cylinders 4 are fixedly connected to the bottom inner wall of the base 1. The drive ends of the multiple hydraulic cylinders 4 are fixedly connected to the same lifting seat 5. The lifting seat 5 is located below the workbench 2. Mounting seats 6 are fixedly connected to the top of both ends of the lifting seat 5.

[0043] Reference Figure 1 , Figure 2 and Figure 3 Multiple mounting holes are equally spaced on both mounting bases 6, and conveyor rollers 13 are rotatably connected in each of the multiple mounting holes. The external of the multiple conveyor rollers 13 located on the same mounting base 6 is connected to the same conveyor belt 14. A universal motor 15 is provided on one side of each of the two mounting bases 6, and the output end of each of the two universal motors 15 is fixedly connected to one end of the corresponding conveyor roller 13.

[0044] Reference Figure 1 , Figure 2 and Figure 8 The workbench 2 is equipped with a positioning and fixing module 8, which includes two connecting rods 801. The two connecting rods 801 are centrally symmetrical. The workbench 2 has two sliding slots. The two connecting rods 801 slide in the corresponding sliding slots. The top of the two connecting rods 801 at their far ends are fixedly connected to movable frames 802. The two movable frames 802 are located above the workbench 2. Multiple flexible rotating rollers 803 are rotatably connected to the two movable frames 802 at equal distances. Airbag components 804 are provided on the opposite side of the two movable frames 802.

[0045] Reference Figure 1 , Figure 2 and Figure 8 Two connecting rod frames 801 are fixedly connected to the outer walls of opposite sides with fixed racks 805, and an AC motor 806 is fixedly connected to the lower end face of the workbench 2. A rotating gear 807 is fixedly connected to the output end of the AC motor 806, and the teeth of the two fixed racks 805 can mesh with the rotating gear 807.

[0046] In specific application scenarios, multiple hydraulic cylinders 4 are simultaneously activated to push the lifting seat 5 and mounting seat 6 upward, making the height of the upper surface of the conveyor belt 14 higher than the flexible rotating roller 803. The universal motors 15 on both sides are then activated to drive the corresponding conveyor rollers 13 to rotate, driving the conveyor belt 14 to transport the tempered glass. When the tempered glass reaches the designated position, the hydraulic cylinders 4 retract, causing the lifting seat 5 and mounting seat 6 to descend. The tempered glass then descends until it is supported by the flexible rotating roller 803. The AC motor 806 is then activated to drive the rotating gear 807 to rotate. Through the meshing of the rotating gear 807 and the fixed rack 805… The connecting rods 801 and movable frame 802 on both sides move towards the center. The airbag 804 pushes the edge of the tempered glass until it is clamped and fixed in the center. The flexible rotating roller 803 rotates with the movement of the tempered glass, effectively reducing rigid contact with the tempered glass and avoiding the possibility of wear. The lateral flexible limit avoids the direct squeezing of the tempered glass edge by traditional clamps. At the same time, the design of alternating support by hydraulic lifting conveyor belt and flexible rotating roller ensures that the bottom surface of the glass receives uniform and distributed flexible support, which structurally reduces the risk of spontaneous explosion caused by stress concentration.

[0047] Working principle: Before surface treatment, the electric telescopic rod 720 pushes the gear component 723 down until it engages with the tooth groove 728. At this time, the stepper motor 722 is started, which drives the winding wheel 725 to rotate through the tooth groove 728 and the connecting seat 727. The winding wheel 725 tightens the winding rope 726, pulling the mounting frame 708 to slide upward along the fixed vertical rod 707 against the elasticity of the telescopic spring 710. Simultaneously, multiple hydraulic cylinders 4 are started to push the lifting seat 5 and the mounting seat 6 to rise, so that the height of the upper surface of the conveyor belt 14 is higher than that of the flexible rotating roller 803. The universal motors 15 on both sides are started to drive the corresponding conveying rollers 13 to rotate, driving the conveyor belt 14 to transport the tempered glass. When the tempered glass reaches the... After the designated position is achieved, hydraulic cylinder 4 retracts, causing the lifting seat 5 and mounting seat 6 to descend. The tempered glass then descends until it is supported by the flexible rotating roller 803. AC motor 806 is then activated, driving rotating gear 807 to rotate. Through the meshing of rotating gear 807 and fixed rack 805, the connecting rods 801 on both sides and the movable frame 802 move towards the center. Airbag 804 pushes the edge of the tempered glass until it is clamped and fixed in the center. The flexible rotating roller 803 rotates with the movement of the tempered glass, effectively reducing rigid contact and preventing wear. Once the tempered glass is positioned and fixed, it is observed through vision camera 706. At the location of the scratch or blemish coated with ultra-fine polishing paste, the drive motor 11 is activated, causing the threaded rod 10 to rotate, which in turn drives the sliding table 9 and the movable frame 3 to slide. Simultaneously, the servo motor 704 is activated, causing the transmission gear 705 to rotate. Through the meshing of the transmission gear 705 and the transmission rack 701, the sliding seat 702 slides, moving the felt polishing wheel 703 above the blemish. At this time, the electric telescopic rod 720 retracts, causing the gear 723 to mesh with the gears 715 on both sides, which in turn causes the threaded rod 713 to rotate, driving the sliding member 716 to slide along the fixed rod 714. This causes the connecting rod 717 to bring the fixed contact block 718 into close contact with the side wall of the movable frame 3, thus fixing the sliding member. To prevent positional shift during polishing, the moving seat 702 is positioned so that gear 723 is engaged in the tooth groove 728 via the electric telescopic rod 720. The stepper motor 722 is started to drive the winding wheel 725 to rotate in the opposite direction, which relaxes the winding rope 726. The telescopic spring 710 elastically returns to its original position, pushing the mounting frame 708 to lower, so that the felt polishing wheel 703 is in close contact with the upper surface of the tempered glass. The polishing motor 711 is started to drive the felt polishing wheel 703 to rotate at low speed to repair and polish the surface defects of the tempered glass. After the polishing operation is completed, the felt polishing wheel 703 rises, and the hydraulic cylinder 4 pushes the lifting seat 5 and the mounting seat 6 to rise, so as to transport the tempered glass.
