Description
Technical Field
[0001] This utility model relates to the field of tempered glass film processing technology, and in particular to a grinding and polishing device for tempered glass film on mobile phone screens. Background Technology
[0002] Tempered glass screen protectors are a type of safety glass material with excellent surface abrasion resistance and extremely high rigidity, typically ranging from 630 to 700 in Vickers hardness. This glass is essentially a pre-stressed product, usually achieved by artificially introducing a compressive stress layer onto its surface through chemical or physical means. When subjected to external forces, this stress layer can initially absorb the impact, thus significantly improving its overall load-bearing capacity, including its resistance to wind pressure, sudden temperature changes, and mechanical impacts. Tempered glass screen protectors used in mobile phone screens utilize this characteristic to provide a higher level of safety protection for the display.
[0003] To optimize user experience, manufacturers typically apply meticulous surface treatments to these protective films—primarily polishing and grinding processes—to enhance their surface smoothness. Current standard processes generally include the following steps: first, multiple protective films are adsorbed and fixed onto a specialized carrier (such as a suction tray); then, the carrier bearing the protective films is tightly fitted onto the surface of a rotating polishing wheel; polishing fluid is sprayed simultaneously during the polishing process; and the film surface is polished by the rotation of the polishing wheel. After the process is complete, the finished film needs to be peeled off from the carrier. However, due to the high flatness and parallelism between the polishing wheel and the tempered glass film, the polishing coolant cannot remain between the polishing wheel and the tempered glass film, rendering the polishing coolant ineffective, resulting in a significant defect. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a polishing equipment for tempered glass screen protectors for mobile phones. By improving the structure of the polishing wheel through grooves, polishing coolant is always replenished and plays a role between the polishing wheel and the surface of the tempered glass screen protector, resulting in high reliability.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a mobile phone screen tempered glass film polishing equipment, including a main body and a polishing device disposed on the main body. The polishing device includes a cylinder-shaped polishing worktable fixedly installed on the main body, a polishing wheel horizontally disposed in the polishing worktable, and a rotary drive mechanism for driving the polishing wheel to rotate. The polishing wheel and the polishing worktable are arranged coaxially. A spray pipe for spraying polishing coolant onto the polishing wheel is disposed directly above the polishing wheel. The pump inlet end of the spray pipe is connected to a return chamber, and a water pump is disposed in the return chamber. Rotatable suction discs are evenly distributed in a ring around the main body. Multiple tempered glass films to be polished are vacuum-adsorbed on the upper surface of the suction discs. A flipping mechanism for driving the suction discs to flip so that the tempered glass film surface adheres to the upper surface of the polishing wheel is evenly distributed in a ring around the main body. A spiral groove is formed on the upper surface of the polishing wheel. The spiral groove extends from the middle of the polishing wheel to the edge of the polishing wheel. A central groove is formed in the center of the polishing wheel. The inner end of the spiral groove is connected to the central groove.
[0006] Preferably, the main body is surrounded by recycling boxes in a ring around its perimeter. The sidewalls of the recycling boxes extend upward in the circumferential direction to form a raised edge. Several recycling boxes are arranged one-to-one below several suction discs. The recycling boxes and suction discs are arranged coaxially, and the size of the recycling boxes is larger than that of the suction discs.
[0007] By adopting the above technical solution, the operator places multiple tempered glass films to be polished on the upper surface of the suction tray. The suction tray holds the films, and then the flipping mechanism flips the tray so that the film surface adheres to the upper surface of the polishing wheel. A water pump provides power, and the return chamber supplies liquid to the polishing wheel through a spray pipe. The polishing wheel is then driven to rotate by a rotary drive mechanism. The polishing liquid assists the polishing wheel in polishing the tempered glass films, improving the polishing effect. After polishing, the flipping mechanism flips the suction tray away from the polishing wheel again. At this time, the tray surface with multiple tempered glass films adhering to it returns to a horizontal position. The collection box located directly below the suction tray collects the polishing liquid flowing down from the tray. The raised edge provides a certain capacity to the collection box, reducing the occurrence of polishing liquid dripping onto the ground, thus preventing ground contamination and inconvenience for subsequent cleaning, and also reducing the occurrence of polishing liquid dripping and splashing onto the operator.
[0008] Preferably, the opening depth of the recycling box gradually increases from the outside to the inside, and a recycling component is provided at the lowest point of the upper surface of the recycling box. By adopting the above technical solution, the gradual increase in the opening depth of the recycling box from the outside to the inside can accumulate the collected polishing liquid together, and then discharge it through the recycling component.
[0009] Preferably, the recycling assembly includes a drain outlet vertically located at the lowest point of the upper surface of the recycling box, a recycling tank positioned directly below the drain outlet, and a flexible plug at the drain outlet. The drain outlet is circular and extends through the upper and lower surfaces of the recycling box. The flexible plug is shaped like an inverted frustum, with its smaller end smaller than the drain outlet and its larger end larger than the drain outlet. The flexible plug, when engaged at the drain outlet, prevents polishing fluid from flowing out. The recycling tank is positioned directly below the drain outlet; removing the flexible plug allows the polishing fluid accumulated near the drain outlet to flow into the recycling tank, facilitating subsequent recycling and reuse.
[0010] Preferably, the top of the flexible plug is equipped with a hook, which allows the operator to easily apply force to pull out the flexible plug.
[0011] Preferably, the flipping mechanism includes a flipping component fixed to the main body, a flipping shaft pivotally connected to the flipping component, a flipping wheel fixed coaxially with the flipping shaft, and a flipping drive mechanism for driving the flipping wheel to rotate. A flipping arm is provided at the bottom of the suction plate, with one end of the flipping arm away from the suction plate fixedly connected to the flipping shaft. When the tempered glass film to be polished is in contact with the upper surface of the polishing wheel, the suction plate is parallel to the polishing wheel. The flipping drive mechanism drives the flipping wheel to rotate, which in turn drives the flipping shaft to rotate, thereby causing the flipping arm to rotate around the axis of the flipping shaft, flipping the suction plate to fit against the edge of the upper surface of the polishing wheel. At this time, the tempered glass film is in contact with the upper surface of the polishing wheel, and the polishing wheel rotates to polish the tempered glass film.
[0012] Preferably, the tilting drive mechanism includes an inverted cylinder, a lifting rack fixedly connected to the piston rod end of the cylinder, and a reduction gear set disposed between the lifting rack and the tilting wheel. The cylinder extends and retracts to drive the lifting rack to move up and down in the vertical direction, and the lifting rack drives the tilting wheel to rotate through the reduction gear set.
[0013] Preferably, the reduction gear assembly includes a transition wheel pivotally connected to the tilting component. The transition wheel meshes with the tilting wheel and with a lifting rack. The size of the transition wheel is smaller than that of the tilting wheel. Because the transition wheel is smaller than the tilting wheel, a cylinder drives the lifting rack to move up and down in the vertical direction. The lifting rack drives the transition wheel to rotate, and the transition wheel drives the meshed tilting wheel to rotate, thereby slowing down the rotation speed of the tilting wheel.
[0014] Preferably, the main body is pivotally connected to a load-bearing spindle in the vertical direction. The load-bearing spindle is coaxially fixed with the polishing wheel. The rotation drive mechanism includes a motor installed inside the main body. The output shaft of the motor is connected to a reducer, and the output end of the reducer is connected to the load-bearing spindle. The motor drives the load-bearing spindle to rotate through the reducer, thereby driving the polishing wheel to rotate and polish the tempered glass film to be polished.
[0015] Preferably, a sleeve seat is fixed vertically at one end of the tilting arm near the suction plate, and a vertical sleeve post is coaxially mounted on the lower surface of the suction plate, with the sleeve post bearing connected inside the sleeve seat. Since multiple tempered glass films to be polished are attached to the edge of the polishing wheel on the suction plate surface, when the motor drives the polishing wheel to rotate, the linear velocity of the polishing wheel farther from the axis is greater than that closer to the axis, resulting in a speed difference across the polishing wheel. This causes the suction plate to rotate, making the tempered glass films on the suction plate more evenly polished by the polishing wheel, increasing the smoothness of the tempered glass films.
[0016] The beneficial effects of this utility model are as follows:
[0017] 1. During the grinding and polishing process, the polishing coolant is continuously pumped to the central tank using a spray pipe. As the polishing wheel continues to rotate, centrifugal force is used to throw the polishing coolant to the surrounding area. When the tempered glass film comes into contact with the polishing wheel, due to the design of the spiral groove, the polishing coolant can still flow along the spiral groove to contact the tempered glass film. During this contact process, the polishing coolant is continuously supplied to the contact position between the tempered glass film and the polishing wheel, ensuring high-quality and continuous grinding and polishing with high reliability.
[0018] 2. The operator places multiple tempered glass films to be polished on the upper surface of the suction tray. The suction tray holds the films and then flips the tray using a turning mechanism, causing the film surfaces to adhere to the upper surface of the polishing wheel. A water pump provides power, and the return chamber supplies liquid to the polishing wheel through a spray pipe. The polishing wheel is then driven to rotate by a rotary drive mechanism. The polishing liquid assists the polishing wheel in polishing the tempered glass films, improving the polishing effect. After polishing, the suction tray is flipped away from the polishing wheel again by the turning mechanism. At this point, the tray surface, which holds multiple tempered glass films, returns to a horizontal position. The collection box located directly below the suction tray collects the polishing liquid that flows down from the tray. The raised edge provides a certain capacity to the collection box, reducing the occurrence of polishing liquid dripping onto the ground to avoid contaminating the ground and making subsequent cleaning inconvenient. It also reduces the occurrence of polishing liquid dripping and splashing onto the operator.
[0019] Third, attaching the flexible plug to the drain outlet can prevent the polishing liquid from flowing out. The recycling bin is placed directly below the drain outlet. Pulling out the flexible plug will allow the polishing liquid accumulated near the drain outlet to flow out into the recycling bin, which is convenient for subsequent recycling and reuse.
[0020] Fourth, because multiple tempered glass films to be polished are attached to the edge of the polishing wheel on the suction plate, when the motor drives the polishing wheel to rotate, the linear velocity of the polishing wheel away from the polishing wheel axis is greater than that of the polishing wheel near the polishing wheel axis. Therefore, there will be a speed difference in different parts of the polishing wheel, which will drive the suction plate to rotate. This makes the tempered glass films on the suction plate more evenly polished by the polishing wheel, increasing the smoothness of the tempered glass films. Attached Figure Description

[0025] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments. The content mentioned in the embodiments is not intended to limit the present invention.
[0026] like Figures 1 to 4 As shown, a mobile phone screen tempered glass film polishing device includes a body 1 and a polishing device mounted on the body 1. The body 1 has a square cross-section. The polishing device includes a cylinder-shaped polishing worktable 2 fixedly mounted on the body 1, a polishing wheel 3 horizontally arranged inside the polishing worktable 2, and a rotary drive mechanism for driving the polishing wheel 3 to rotate. The axis of the polishing worktable 2 coincides with the center line of the body 1. A load-bearing main shaft is pivotally connected to the body 1 in the vertical direction via bearings. The load-bearing main shaft can rotate around its own axis. The polishing wheel 3 and the polishing worktable 2 are arranged coaxially. The load-bearing main shaft is coaxially fixed to the bottom of the polishing wheel 3. The rotary drive mechanism includes a motor 4 fixed inside the body 1. The output shaft of the motor 4 is connected to a reducer 5. The output end of the reducer 5 is connected to the load-bearing main shaft. A spiral groove 31 is formed on the upper surface of the polishing wheel, extending from the middle of the polishing wheel to the edge of the polishing wheel. A central groove 32 is formed in the center of the polishing wheel, and the inner end of the spiral groove 31 communicates with the central groove 32.
[0027] Reference Figure 3 During the grinding and polishing process, the polishing coolant is continuously pumped to the central groove using a spray pipe. As the polishing wheel 3 continues to rotate, centrifugal force is used to throw the polishing coolant to the surrounding area. When the tempered glass film comes into contact with the polishing wheel 3, due to the design of the spiral groove 31, the polishing coolant can still flow along the spiral groove 31 to contact the tempered glass film. During this contact process, the polishing coolant is continuously supplied to the contact position between the tempered glass film and the polishing wheel 3, ensuring high-quality and continuous grinding and polishing with high reliability.
[0028] Reference Figure 2A spray pipe 6 for spraying polishing coolant onto the polishing wheel 3 is provided directly above the polishing wheel 3. The outlet end of the spray pipe 6 is positioned directly opposite the center of the polishing wheel 3. The pump inlet end of the spray pipe 6 is connected to a return chamber 7, which is fixed on the main body 1. A water pump is installed inside the return chamber 7, which provides power and supplies the polishing wheel 3 with coolant through the spray pipe 6.
[0029] The top of the main body 1 is evenly distributed with flip-able suction disks 8 in a ring around its perimeter. In this embodiment, four suction disks 8 are provided. The suction disks 8 are arranged circumferentially on the outside of the polishing worktable 2 and located at the four corners of the main body 1. Multiple pieces of tempered film to be polished are vacuum adsorbed on the upper surface of the suction disks 8.
[0030] Reference Figure 2 and Figure 4 Four recycling boxes 9 are fixedly installed circumferentially on the main body 1. The recycling boxes 9 are disc-shaped and horizontally arranged. The side walls of the recycling boxes 9 extend upward to form a raised edge 10. The four recycling boxes 9 are correspondingly arranged directly below the four suction discs 8. The recycling boxes 9 and the suction discs 8 are arranged coaxially. The size of the recycling boxes 9 is larger than that of the suction discs 8. The opening depth of the recycling boxes 9 gradually increases from the outside to the inside. A recycling component is provided at the lowest point of the upper surface of the recycling boxes 9. The recycling component includes a drain outlet 11 vertically opened at the lowest point of the upper surface of the recycling box 9 (i.e., the center of the recycling box 9), a recycling tank 12 located directly below the drain outlet 11, and a flexible plug 13 located at the drain outlet 11. The drain outlet 11 penetrates the upper and lower disc surfaces of the recycling box 9. The flexible plug 13 is in the shape of an inverted frustum. The smaller end of the flexible plug 13 is smaller than the size of the drain outlet 11, and the larger end of the flexible plug 13 is larger than the size of the drain outlet 11. The top of the flexible plug 13 is equipped with a hook. The flexible plug 13 can be locked at the drain outlet 11 to prevent polishing liquid from flowing out. The recycling box 12 is placed directly below the drain outlet 11. By pulling out the flexible plug 13 with the hook, the polishing liquid accumulated near the drain outlet 11 can flow out into the recycling box 12, which is convenient for subsequent recycling and reuse.
[0031] The main body 1 is provided with four circumferentially rotating drive mechanisms for driving the suction disk 8 to rotate so that the tempered film surface is attached to the upper surface of the polishing wheel 3. The four rotating mechanisms are circumferentially arranged on the outside of the polishing worktable 2 and located at the four corners of the top of the main body 1. One rotating mechanism is used to drive one suction disk 8 to rotate.
[0032] Specifically, the flipping mechanism includes a flipping component 15 fixed on the main body 1, a flipping shaft 16 pivotally connected to the flipping component 15, a flipping wheel 17 coaxially fixed with the flipping shaft 16, and a flipping drive mechanism for driving the flipping wheel 17 to rotate. The flipping shaft 16 is horizontally arranged, and a flipping arm 18 is provided at the bottom of the suction plate 8. The end of the flipping arm 18 away from the suction plate 8 is fixedly connected to the flipping shaft 16. In order to reduce the installation height of the flipping shaft 16, a clearance groove 21 is correspondingly provided on the circumferential side wall of the polishing worktable 2 for the flipping shaft 16 to rotate and insert. A sleeve seat 19 is fixed vertically at the end of the flipping arm 18 near the suction plate 8. A vertical sleeve post 20 is coaxially mounted on the lower surface of the suction plate 8, and the sleeve post 20 is bearing connected in the sleeve seat 19. When the suction plate 8 flips until the tempered film to be polished is in contact with the upper surface of the polishing wheel 3, the suction plate 8 is parallel to the polishing wheel 3.
[0033] Reference Figure 4 The aforementioned flipping drive mechanism includes an inverted cylinder 21, a lifting rack 22 fixedly connected to the piston rod end of the cylinder 21, and a reduction gear assembly disposed between the lifting rack 22 and the flipping wheel 17. The cylinder 21 is fixedly installed inside the body 1. The reduction gear assembly includes a transition wheel 23 pivotally connected to the flipping component 15. The transition wheel 23 can rotate around its own axis. The transition wheel 23 meshes with the flipping wheel 17 and the lifting rack 22. The size of the transition wheel 23 is smaller than that of the flipping wheel 17. The lifting rack 22 is located on the side of the transition wheel 23 closer to the polishing worktable 2. The flipping wheel 17 is located above the transition wheel 23. The cylinder 21 drives the lifting rack 22 to move up and down in the vertical direction. The lifting rack 22 drives the transition wheel 23 to rotate. The transition wheel 23 drives the meshing flipping wheel 17 to rotate, thereby slowing down the rotation speed of the flipping wheel 17. When the operator drives the lifting rack 22 to rise through the cylinder 21, the transition wheel 23 drives the turning wheel 17 to rotate. The rotation of the turning wheel 17 drives the turning arm 18 connected to the suction plate 8 to rotate, and the suction plate 8 flips. After the suction plate 8 flips 180°, the suction plate 8 returns to the horizontal state. At this time, the multiple tempered film surfaces to be polished adsorbed by the suction plate 8 are in contact with the edge of the polishing wheel 3.
[0034] The implementation principle of this embodiment is as follows: The operator places multiple tempered glass films to be polished on the suction plate 8. The suction plate 8 adsorbs the multiple tempered glass films to be polished. Then, the cylinder 21 drives the lifting rack 22 to rise vertically. The transition wheel 23 and the tilting wheel 17 mesh. The lifting rack 22 is located on the side of the transition wheel 23 near the polishing worktable 2. The tilting wheel 17 is located above the transition wheel 23. The transition wheel 23 drives the tilting wheel 17 to rotate. The rotation of the tilting wheel 17 drives the tilting arm 18 connected to the suction plate 8 to rotate. The suction plate 8 tilts. After the suction plate 8 has tilted 30°, the suction plate 8 returns to a horizontal state. At this time, the film surfaces of the multiple tempered glass films adsorbed by the suction plate 8 are in contact with the edge of the polishing wheel 3. The return chamber 7 supplies liquid to the polishing wheel 3 through the water pump and spray pipe 6. Then, the motor 4 is started to drive the polishing wheel 3 to rotate, and the polishing process begins. The liquid-assisted polishing wheel 3 polishes the tempered glass film, improving the polishing effect. After polishing, the lifting rack 22 is driven by the cylinder 21 to descend vertically, and the suction plate 8 is flipped in the opposite direction. At this time, the suction plate 8 adsorbs the upper surface of multiple tempered glass films to be polished and returns to a horizontal upward state. The recycling box 9 located directly below the suction plate 8 collects the polishing liquid flowing down from the suction plate 8. The convex edge 10 provides a certain capacity for the recycling box 9, which can reduce the occurrence of polishing liquid dripping onto the ground to avoid contaminating the ground and making subsequent cleaning inconvenient. At the same time, it also reduces the occurrence of polishing liquid dripping and splashing onto the operator. When the polishing liquid in the recycling box 9 accumulates a lot, the recycling box 12 is placed directly below the drain outlet 11. By pulling out the flexible plug 13 with the hook, the polishing liquid accumulated near the drain outlet 11 can flow out into the recycling box 12 for subsequent recycling and reuse.
