Description

Technical Field

[0001] This utility model belongs to the field of glass cover processing technology, specifically relating to an anti-drop polishing disc mechanism and polishing machine for mobile phone glass covers. Background Technology

[0002] The flatness, smoothness, and light transmittance of a mobile phone's glass cover surface are key components affecting the overall quality and user experience of the phone. To meet market demands for high precision and high quality in mobile phone glass covers, polishing is an indispensable and crucial step in the production process. Polishing effectively removes scratches, burrs, unevenness, and other defects generated during previous processing, significantly improving surface quality and ensuring the phone's aesthetic appeal and performance.

[0003] Currently, glass cover plates are typically polished using a polishing machine. This machine can polish the camera platform area of ​​the glass cover plate. The polishing machine mainly consists of a polishing platform with a polishing disc. The polishing disc has grooves for placing the glass cover plate to be processed. A polishing pressure plate is located on top of the polishing platform. When the glass cover plate is placed in the groove, the polishing pressure plate presses the polishing disc against the polishing platform. The polishing disc rotates relative to the polishing pressure plate as the polishing platform rotates, and the friction generated by this rotation polishes the glass cover plate.

[0004] However, under the combined effects of high-speed rotation, applied pressure, and polishing fluid, the friction between the glass cover and the polishing disc is insufficient to completely overcome the centrifugal force or other disturbances generated by the rotation, resulting in the glass cover falling off, flying off, or shifting. There is a risk of the glass cover falling off during the polishing process. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides an anti-drop polishing disc mechanism and polishing machine for mobile phone glass covers. The glass cover is positioned in a fixed groove by a limiting component, which helps reduce the risk of the glass cover falling off and improves the safety of the glass cover polishing process.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0007] In a first aspect, this utility model provides an anti-detachment polishing disc mechanism for mobile phone glass covers, comprising a polishing platform; a polishing disc disposed on the polishing platform, the polishing disc having a fixing groove for placing the glass cover; a limiting component disposed within the fixing groove, the limiting component including a limiting plate, the limiting plate covering the glass cover, a connecting member being provided between the limiting plate and the polishing disc, the connecting member fixing the limiting plate to prevent the glass cover from detaching from the fixing groove; and a polishing pressure plate cooperating with the polishing platform to press the polishing disc.

[0008] In some implementations, the polishing disc has a top groove that is connected to the fixing groove; the limiting plate includes an extension portion, and when the limiting plate covers the glass cover, the extension portion is located in the top groove, and the connector fixes the extension portion in the top groove.

[0009] In some implementations, a limiting hole is provided on the extension, and a connecting hole is provided on the inner wall of the top groove. The connector includes rubber particles, which pass through the limiting hole and the connecting hole to restrict the movement of the limiting plate.

[0010] In some implementations, the polishing disc has a bottom groove, which is opposite to the top groove. The connector includes a gasket, which is disposed in the bottom groove. The gasket has a positioning hole, and the adhesive particle passes through the connector hole into the positioning hole. The gasket, the polishing disc, and the limiting plate are connected.

[0011] In some implementations, the outer wall of the adhesive particle is provided with an anti-detachment groove to prevent the gasket from detaching, and when the adhesive particle passes through the positioning hole, the gasket is fitted inside the anti-detachment groove.

[0012] In some implementations, the polishing disc has a retrieval groove, which is located at the edge of the opening of the fixing groove and is connected to the fixing groove.

[0013] In some implementations, the limiting plate has a receiving groove for accommodating the camera platform of the glass cover plate.

[0014] In some implementations, the limiting plate is adapted to the fixing groove.

[0015] In some implementations, the polishing platform is provided with a return channel for the polishing fluid to flow out.

[0016] Secondly, this utility model provides a polishing machine, including the aforementioned anti-drop polishing disc mechanism for mobile phone glass covers.

[0017] In summary, this utility model has at least the following advantages:

[0018] 1. The anti-detachment polishing disc mechanism for mobile phone glass covers provided by this utility model involves placing the glass cover to be polished into a fixed groove during polishing. A limiting plate is then placed on top of the glass cover, and the limiting plate is fixed in the fixed groove via a connector. The limiting plate prevents the glass cover from detaching from the fixed groove. A polishing pressure plate presses down on the polishing platform to press the polishing disc, reliably confining the glass cover within the fixed groove, making it difficult to detach. When the polishing platform drives the polishing disc to rotate synchronously, the polishing pressure plate polishes the camera platform area of ​​the glass cover. The limiting component allows the glass cover to overcome interference from high-speed rotation and polishing fluid, solving the problem of easy detachment during polishing. This helps ensure the polishing effect of the glass cover, improving polishing safety and production efficiency.

[0019] 2. The polishing machine provided by this utility model can be used to polish glass cover plates of different specifications, especially smooth and small-sized glass cover plates. It can maintain the stability of the glass cover plate in the presence of polishing liquid, making it safe to use and achieving excellent polishing effect. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Example 1:

[0029] Please see Figure 1 This utility model discloses an anti-detachment polishing disc mechanism for mobile phone glass covers, comprising a polishing platform 1, specifically, the polishing platform 1 can be a frustum. A polishing disc 2 is provided on the polishing platform 1, preferably, but not limited to, a fiberboard. A fixing groove 21 for placing a glass cover 5 is provided through the polishing disc 2. When the glass cover 5 to be polished is placed in the fixing groove 21, the glass cover 5 contacts the polishing disc 2, and polishing is achieved under the action of friction. Specifically, multiple fixing grooves 21 can be provided, spaced apart around the central axis of the polishing disc 2. Placing the glass cover 5 to be polished in the fixing groove 21 improves the efficiency of the polishing process.

[0030] A limiting component 3 is provided within the fixing groove 21 of the polishing disc 2. The limiting component 3 prevents the glass cover plate 5 from disengaging from the fixing groove 21 during the polishing process. The limiting component 3 includes a limiting plate 31 for covering the glass cover plate 5. The limiting plate 31 is preferably, but not limited to, a fiberboard. Specifically, the limiting plate 31 may be smaller than the size of the glass cover plate 5, and the camera platform 51 of the glass cover plate 5 is fully exposed for polishing. In other specific embodiments, the limiting plate 31 may be larger than the size of the glass cover plate 5. A receiving groove 313 for accommodating the camera platform 51 of the glass cover plate 5 is formed through the limiting plate 31. The camera platform 51 is positioned within the receiving groove 313, allowing for polishing and grinding of the unobstructed surface of the camera platform 51. Furthermore, the limiting plate 31 is adapted to the fixing groove 21, and the limiting plate 31 fully covers the glass cover plate 5 to position the entire glass cover plate 5, which helps to improve the stability of the glass cover plate 5 during the polishing process.

[0031] A connector 32 is provided between the limiting plate 31 and the polishing disc 2. The connector 32 fixes the limiting plate 31 to prevent the glass cover plate 5 from disengaging from the fixing groove 21. A polishing pressure plate 4 is provided on one side of the polishing platform 1. The polishing pressure plate 4 applies pressure to press the polishing disc 2 onto the polishing platform 1.

[0032] Before polishing, the glass cover plate 5 to be polished is placed in the fixing groove 21, and the limiting plate 31 is closed. The connecting piece 32 connects the limiting plate 31 and the polishing disc 2. The limiting plate 31 can position the glass cover plate 5 in the fixing groove 21. When the polishing platform 1 drives the polishing disc 2 to rotate relative to the polishing pressure plate 4, friction is generated between the polishing pressure plate 4 and the camera platform 51. The polishing pressure plate 4 uses friction to polish. If the glass cover plate 5 falls off, it will cause product scrapping, equipment shutdown for cleaning, equipment damage or other safety hazards, seriously affecting production efficiency and yield. The limiting plate 31 and connecting piece 32 of this utility model limit the glass cover plate 5 in the fixing groove 21, making it less likely for the glass cover plate 5 to fall off and fly away, which helps to reduce operational risks and ensure good polishing effect.

[0033] Example 2:

[0034] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the limiting component 3 of this utility model. Please refer to [link / reference]. Figures 1-4 .

[0035] Please see Figure 1 and Figure 2 In this embodiment, the polishing disc 2 has a top groove 22, which is located on one side of the fixing groove 21 and communicates with it. Specifically, the top groove 22 can be a rectangular groove. The limiting plate 31 includes an extension 311. When the limiting plate 31 covers the glass cover plate 5, the extension 311 is located in the top groove 22, and the connecting member 32 fixes the extension 311 in the top groove 22.

[0036] Please see Figures 2-4 In a preferred embodiment, a limiting hole 312 is formed through the extension 311, and a connecting hole 23 is formed on the inner wall of the top groove 22. Specifically, multiple limiting holes 312 and connecting holes 23 are provided and are correspondingly arranged. The connector 32 includes adhesive particles 321, which are inserted into the limiting holes 312 and connecting holes 23 to restrict the movement of the limiting plate 31, thereby achieving the positioning of the glass cover 5.

[0037] In some specific embodiments, the adhesive particles 321 are preferably, but not limited to, rubber particles 321, polyurethane particles 321, and silicone particles 321. The adhesive particles 321 have good elasticity, wear resistance, and high-temperature resistance, and are not easily scratched by the glass cover plate 5. Specifically, the adhesive particles 321 can be cylindrical, and they are easy to insert into the limiting hole 312 and the connecting hole 23. The adhesive particles 321 are respectively press-fitted with the limiting plate 31 and the polishing disc 2. The adhesive particles 321 rely on their own elastic deformation to generate continuous clamping force to be clamped in the limiting hole 312 and the positioning hole 3221, thus connecting the limiting plate 31 and the polishing disc 2.

[0038] In some specific embodiments, the polishing disc 2 is provided with a bottom groove 24, which is opposite to the top groove 22. The connector 32 includes a gasket 322, which is disposed in the bottom groove 24. The gasket 322 has a positioning hole 3221, which corresponds to the connecting hole 23. The adhesive particle 321 passes through the connecting hole 23 and into the positioning hole 3221. The gasket 322, the polishing disc 2, and the limiting plate 31 are connected. The adhesive particle 321 is designed with an inverted loop through the gasket 322, which helps to improve the stability of the connection between the adhesive particle 321 and the limiting plate 31, the polishing disc 2, and the gasket 322, so as to adapt to the high-speed rotational working environment of polishing.

[0039] Furthermore, an anti-detachment groove 3211 is provided on the outer wall of the granule 321. Specifically, the anti-detachment groove 3211 can be an annular groove. When the granule 321 passes through the positioning hole 3221, the gasket 322 is sleeved in the anti-detachment groove 3211. The anti-detachment groove 3211 restricts the gasket 322 from falling off the granule 321 at will, which is beneficial to improving the stability of the connection.

[0040] When assembling the limiting component 3, the gasket 322 is first placed in the bottom groove 24, and the adhesive granules 321 pass through the positioning hole 3221 and the connecting hole 23, connecting the gasket 322 and the polishing disc 2. Then, the glass cover plate 5 to be polished is placed in the fixing groove 21, and the limiting plate 31 covers the glass cover plate 5. The adhesive granules 321 are squeezed to pass through the limiting hole 312, and the adhesive granules 321 reliably connect the limiting plate 31, the polishing disc 2, and the gasket 322 through an interference fit. The limiting plate 31 presses the glass cover plate 5 into the fixing groove 21. When the polishing platform 1 and the polishing pressure plate 4 cooperate to perform polishing operations, the glass cover plate 5 is restricted in the fixing groove 21 and is difficult to remove. After polishing is completed, the limiting plate 31 is removed from the adhesive granules 321. The limiting component 3 has a simple structure and is easy to manufacture, install, and maintain.

[0041] In some specific embodiments, the polishing disc 2 is provided with a retrieval groove 25, which is located at the edge of the opening of the fixing groove 21 and communicates with the fixing groove 21. The retrieval groove 25 facilitates the placement and removal of the limiting plate 31, improving ease of use. Specifically, the polishing platform 1 is provided with a return groove 11 for the polishing liquid to flow out, which can be an annular groove.

[0042] Example 3:

[0043] This embodiment, based on the above embodiments, provides a polishing machine. Please refer to [link / reference]. Figure 1 The polishing platform 1 includes the aforementioned anti-detachment polishing disc 2 mechanism for the mobile phone glass cover 5. Multiple positioning posts 12 are provided on the polishing platform 1, spaced apart along the arc-shaped edge of the platform. A return groove 11 surrounds the outer side of the positioning posts 12. Multiple edge holes 26 are formed on the arc-shaped edge of the polishing disc 2, corresponding to the positioning posts 12, so that the positioning posts 12 pass through the edge holes 26, achieving positioning of the polishing disc 2. Specifically, the polishing platform 1 is connected to a driving component. When the driving component drives the polishing platform 1 to rotate, the polishing platform 1 drives the polishing disc 2 to rotate synchronously, and the polishing pressure plate 4 and the polishing platform 1 press together to achieve polishing.

[0044] The polishing machine of this utility model, through the anti-drop polishing disc 2 mechanism, can be used to polish glass cover plates 5 of different specifications, especially smooth and small-sized glass cover plates 5. It ensures that the glass cover plate 5 maintains its limited stability in the presence of polishing liquid, making it safe to use and achieving excellent polishing effect.
