Description

Technical Field

[0001] This utility model relates to the field of mobile phone screen polishing technology, and in particular to a double-sided polishing device for curved mobile phone screens. Background Technology

[0002] Double-sided polishing equipment for curved mobile phone screens plays several important roles: it removes minor scratches, bumps, and other imperfections that occur during the manufacturing process, resulting in a smooth, mirror-like surface. This not only provides a high-quality visual experience but also enhances the overall aesthetics of the phone. Fine polishing reduces surface roughness, thereby improving screen transparency. This makes the phone display clearer, brighter, and more vibrant, with higher color fidelity, providing users with a better visual experience. Existing equipment requires disassembling and reassembling the phone before polishing the other side when polishing both curved sides.

[0003] However, existing technologies, such as Chinese Publication No. CN113146454A, "A Double-Sided Polishing Equipment and Polishing Method for Curved Mobile Phone Outer Screens," disclose a double-sided polishing equipment and method for curved mobile phone outer screens, belonging to the technical field of mobile phone outer screen processing equipment. This invention includes a bracket, a base plate at the top of the bracket, a mounting cylinder at the top of the base plate, a moving device on one side of the mounting cylinder, a fixing plate at the top of the moving device, a pad at the top of the fixing plate, and a first spring inside the mounting cylinder. This invention, through the arrangement of the mounting cylinder, the first spring, the connecting column, and the second spring, can support the connecting column with the first spring, preventing the mobile phone outer screen from breaking due to excessive pressure from the operator pressing down on the motor box during polishing. Furthermore, the second spring can buffer the impact when the first spring lifts the connecting column, preventing excessive vibration.

[0004] However, this device lacks an angle swing structure, preventing it from adjusting the angle according to the curved surface of the phone's outer side to better adapt to the polishing equipment. This makes it impossible to ensure that the polishing tool maintains good contact with the outer screen surface at all times, resulting in uneven polishing intensity and leading to localized over- or under-polishing. Furthermore, the device lacks a rotation structure, meaning that after angle adjustment, it cannot be directly rotated to polish the other side of the phone. The phone must be disassembled and reinstalled before polishing the other side, increasing labor costs. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art, such as the inability to adjust the angle according to the curved surface of the outer side of the mobile phone to better adapt to the polishing equipment, the inability to ensure that the polishing tool and the outer screen surface always maintain good contact, the uneven distribution of polishing force leading to local over-polishing or under-polishing, and the inability to directly rotate the phone to polish the other side after adjusting the angle, requiring disassembly and reinstallation of the phone to polish the other side, which increases labor costs.

The inner surface of the second shaft plate 8 is rotatably connected to the outer surface of the rotating rod 5, and a main rod 9 is rotatably connected to the inner surface of the connecting plate 7. The mobile phone above the rod sleeve 4, the first shaft plate 6, the second shaft plate 8, and the connecting plate 7 rotates about the rotating rod 5 as an axis and adapts to the curvature of the side of the mobile phone, so that the curved surface of one side of the mobile phone can be polished.

[0027] like Figures 1 to 5 As shown, a driven bevel gear 10 is fixedly connected to the bottom of the main rod 9. An active bevel gear 11 is meshed with the outer surface of the driven bevel gear 10. The active bevel gear 11 is fixedly embedded in the outer surface of the rotating rod 5. The active bevel gear 11, which rotates with the rotating rod 5, will drive the main rod 9 and the fixed rod 15 to rotate inside the connecting plate 7 under the meshing action of the driven bevel gear 10.

[0028] like Figures 1 to 5 As shown, a first motor 12 is fixedly connected to the top of the pressure platform 1. The output end of the first motor 12 is fixedly connected to one side of the rod sleeve 4. After the first motor 12 is powered on, it will drive the rod sleeve 4, the first shaft plate 6, the second shaft plate 8 and the mobile phone above the connecting plate 7 to rotate around the rotating rod 5 as the axis.

[0029] like Figures 1 to 5 As shown, a second motor 13 is fixedly connected to the top of the pressure platform 1. The output end of the second motor 13 is fixedly connected to one end of the rotating rod 5. After the second motor 13 is powered on, it will drive the rotating rod 5 to rotate inside the first side plate 2 and the second side plate 3.

[0030] like Figures 1 to 5 As shown, a mounting plate 14 is fixedly connected to the top of the main rod 9, and multiple fixing rods 15 are fixedly connected to the bottom of the mounting plate 14. The ends of the multiple fixing rods 15 away from the mounting plate 14 are fixedly connected to the outer surface of the main rod 9. The main rod 9 and the fixing rods 15 rotate inside the connecting plate 7, which will rotate the other side of the mobile phone to the top.

[0031] like Figures 1 to 5 As shown, a limiting plate 16 is fixedly connected to the top of the mounting plate 14. A wedge 17 is provided on the mounting plate 14. A wedge block 18 is movably embedded in the inner surface of the wedge 17. The moving plate 19 and the wedge block 18 at the bottom can only move along the slotting direction of the wedge 17.

[0032] like Figures 1 to 5 As shown, a movable plate 19 is fixedly connected to the top of the wedge 18, and a fixed plate 20 is fixedly connected to the top of the mounting plate 14. A threaded rod 21 is threadedly connected to the inner surface of the fixed plate 20. One end of the threaded rod 21 is rotatably connected to one side of the movable plate 19. Rotating the thread will push the movable plate 19.

[0033] like Figures 1 to 5 As shown, a rotating wheel 22 is fixedly connected to one end of the threaded rod 21 away from the moving plate 19. A rocker arm 23 is movably embedded inside the rotating wheel 22. The rocker arm 23 and the rotating wheel 22 drive the threaded rod 21 to rotate inside the fixed plate 20.

[0034] Working principle: First, place the curved phone to be polished on top of the mounting plate 14. Then, through the rocker arm 23 and the rotating wheel 22, drive the threaded rod 21 to rotate inside the fixed plate 20. The rotating thread will push the moving plate 19, causing the moving plate 19 and the bottom wedge 18 to move along the slotting direction of the wedge 17. The moving plate 19 and the limiting plate 16 move closer to each other, clamping and fixing the phone inside. When the phone is in a horizontal position, the front of the phone can be polished. When it is necessary to polish the side curved surface of the phone, start the external power supply of the first motor 12 on the pressure table 1. The first motor 12 has a power rating of 550W. After the first motor 12 is powered on, it will drive the rod sleeve 4, the first shaft plate 6, and the first... The phone, positioned above the dual-axis plate 8 and connecting plate 7, rotates around the rotating rod 5 as its axis, adapting to the curvature of the phone's side. This allows for the polishing of one side of the phone's curved surface. When polishing the other side of the phone is required, the external power supply of the second motor 13 can be directly activated. The second motor 13 is a BYG model with a rated power of 500W. After being powered on, the second motor 13 will drive the rotating rod 5 to rotate inside the first side plate 2 and the second side plate 3. The active bevel gear 11, which rotates with the rotating rod 5, will, through meshing with the driven bevel gear 10, drive the main rod 9 and the fixed rod 15 to rotate inside the connecting plate 7, thus rotating the other side of the phone to the top, whereby the other side of the phone can then be polished.
