[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0030] During the manufacturing process of the cover glass, the cover glass is polished by a pig hair brush, a leather strip brush, a resin fiber brush or a mixed hair brush, etc. However, the gaps between the bristles of these brushes are too large, resulting in low polishing efficiency, so that the production volume cannot meet the demand.

[0031] If the number of bristles is increased to reduce the gap between the bristles, although the number of polishing times can be reduced to improve the polishing efficiency, the material of the bristles is hard, which leads to an increase in friction between the bristles and the cover glass when the number increases, which makes it easy to scratch the cover glass and increase the defective rate, which in turn reduces the production volume. For this reason, the inventor creatively proposed to replace the bristles with a polishing part made of cotton and linen. When the polishing part is moved onto the cover glass, the softness of the multiple polishing parts allows the multiple polishing parts to be bent separately to fill the gap between the polishing parts, and even stacked on the surface of the cover glass after bending, so that every position in the covered area can be covered by the polishing part as much as possible, thereby reducing the number of polishing times and improving the polishing efficiency, so that the production volume meets the demand.

[0032] The present application embodiment provides a polishing device, see Figure 1 and Figure 2 As shown, the polishing device includes: a fixed plate 1, a first structural member 2 and a second structural member 3, the first structural member 2 is connected to the fixed plate 1 and has a first elasticity; the second structural member 3 includes: a connecting part and a plurality of polishing parts, the connecting part has a second elasticity, the plurality of polishing parts are connected to the side of the first structural member 2 away from the fixed plate 1 through the connecting part, and the polishing part is made of cotton and linen material.

[0033] The fixed disk 1 may be as follows Figure 1 and Figure 2 The circular plate may be a rectangular plate or a plate-like structure of other shapes. The fixed disk 1 may be connected to a polishing device, so that when the polishing device provides a lifting force to the fixed disk 1, the polishing portion on the fixed disk 1 can switch between abutting the cover glass and not abutting the cover glass, and when the polishing portion abuts the cover glass, when the polishing device provides a translational force or a rotational force to the fixed disk 1, the polishing portion can move with the fixed disk 1 to perform translational polishing or rotational polishing on the surface of the cover glass. The fixed disk 1 may be a structure made of a harder material such as plastic to ensure the structural stability of the fixed disk 1 during high-speed polishing, thereby extending the service life of the fixed disk 1; for example: see Figure 1 and Figure 2 As shown, the fixing plate 1 is made of PVC (Polyvinyl chloride) material, and has a hardness range of 85-95p and a thickness range of 25-40mm. The thickness refers to the distance between the surface of the fixing plate 1 away from the first structural member 2 and the surface close to the first structural member 2.

[0034] The first structural member 2 may be a sponge, a high foam, or other structures having a first elasticity; for example: Figure 1 and Figure 2As shown, the first structural member 2 is a sponge, and has a hardness range of 20-40p and a thickness range of 70-100mm. The thickness refers to the distance between the surface of the first structural member 2 close to the fixed plate 1 and the surface close to the second structural member 3.

[0035] In the second structural member 3, the connecting portion may be as follows Figure 1 The ring shown in the figure is connected to a circle of annular area on the side of the first structural member 2 away from the fixed disk 1; the connecting part can also be circular to connect to the circular area on the side of the first structural member 2 away from the fixed disk 1; the connecting part can also be other shapes. Multiple polishing parts are connected to the side of the first structural member 2 away from the fixed disk 1 through the connecting part, and the polishing part is made of cotton and linen material. The connecting part and the multiple polishing parts can form a structure similar to a carpet, and the connecting part can be a leather (rubber leather, silicone leather) structure on the carpet that has elasticity and is connected to multiple wool, cloth strips or cotton strips, etc. The leather structure has a second elasticity, and the polishing part can be a cotton and linen fabric such as wool, cloth strips, cotton strips, etc. connected to the connecting part. When the polishing device moves the polishing part onto the cover glass, multiple polishing parts can be bent to fill the gap between the polishing parts, and even be stacked on the surface of the cover glass after bending, so that every position in the covered area can be covered by the polishing part as much as possible, thereby reducing the number of polishing times; for example: the length of the polishing part is 10-30mm, so during the polishing process, each polishing part can cover a length area of ​​10-30mm on the cover glass, and multiple polishing parts are stacked on each other, so that every position in the covered area can be covered by the polishing part as much as possible, thereby reducing the number of polishing times.

[0036] In one example, see Figure 1 and Figure 2 As shown, the polishing device includes: a fixed plate 1, a first structural member 2 and a second structural member 3 connected in sequence by glue, the first structural member 2 is connected to the fixed plate 1 and has a first elasticity, the second structural member 3 includes: a connecting part and a plurality of polishing parts, the connecting part has a second elasticity, the plurality of polishing parts are connected to the side of the first structural member 2 away from the fixed plate 1 through the connecting part, and the polishing part is made of cotton and linen material so that the connecting part and the plurality of polishing parts form a carpet structure.

[0037] In this embodiment, the polishing device includes a fixed plate 1, a first structural member 2 and a second structural member 3 connected in sequence, and the polishing part on the second structural member 3 is made of cotton and linen material. In this way, the polishing device moves to carry the polishing part in the process of polishing the surface of the cover glass. Due to the softness of the cotton and linen material, the probability of scratching the cover glass can be reduced, so that the defective rate can be reduced and the production volume can be increased. The softness of the cotton and linen material can reduce the polishing marks left on the cover glass, so that the cleaning procedure can be shortened and the production volume can be increased. At the same time, the softness of the cotton and linen material allows multiple polishing parts to be bent to fill the gaps between the polishing parts and even stacked on each other to cover every position in the local area of ​​the cover glass through surface contact. Compared with the method of polishing back and forth multiple times with the same number of polishing parts and a gap between the hard bristles, the number of polishing times can be reduced to improve the polishing efficiency and thus increase the production volume, so that the production volume can meet the demand; moreover, the softness of the polishing part reduces the wear of the polishing part itself during the polishing process, so as to extend the service life of the polishing part. In addition, the first structural member 2 and the connecting member located between the fixed plate 1 and the polishing part are elastic, so that during the polishing process, the first structural member 2 and the connecting member can lead the polishing part to adaptively deform according to the surface contour of the cover glass to meet the polishing of cover glasses with different contours (such as curved surfaces, flat surfaces). At the same time, a buffering force can be provided to the cover glass in the direction from the polishing part to the fixed plate 1 during the polishing process to better protect the cover glass.

[0038] In some embodiments, the thickness of the first structural member 2 from the fixed plate to the second structural member 3 is greater than the thickness of the connecting portion, and the first elasticity is greater than the second elasticity. In this way, the first structural member 2 can produce a greater deformation to adapt to a non-planar position with a greater degree of bending on the cover glass, such as a position with a greater degree of curvature, and provide a greater buffer force to the cover glass to better protect the cover glass; at the same time, the elasticity of the connecting portion directly connected to the polishing portion is less than the elasticity of the first structural member 2, so that the connecting portion can transfer the polishing force transmitted from the fixed plate 1 to the first structural member 2 to the polishing portion as much as possible, thereby ensuring the polishing effect.

[0039] In some embodiments, see Figure 1 As shown, the fixing plate 1 is provided with a first through hole 11; the connecting portion is provided with a second through hole; the first structural member 2 is a structural member with water absorption performance, and the two ends of the first structural member 2 are respectively opposite to the first opening of the first through hole 11 and the second opening of the second through hole.

[0040] In one example, the first structural member 2 can be a sponge with a hardness range of 20-40p and a thickness range of 70-100mm. In this way, the polishing liquid can first enter the first through hole 11, and then be transported to the first structural member 2 through the first opening of the first through hole 11, and the first structural member 2 can absorb the polishing liquid transported from the first through hole 11 and provide it to the second opening of the second through hole, and finally the second through hole provides the liquid to the polishing part and the cover glass contacted by the polishing part. The polishing liquid makes the polished surface of the cover glass cleaner after polishing, and at the same time can reduce the temperature of the polishing part and the cover glass during the polishing process to ensure that the polishing process is carried out safely within the preset temperature range.

[0041] When the fixing plate 1 is provided with a first through hole 11; the connecting portion is provided with a second through hole; the first structural member 2 is a structural member with water absorption performance, and the two ends of the first structural member 2 are respectively opposite to the first opening of the first through hole 11 and the second opening of the second through hole, in order to transport more polishing liquid to the polishing portion and the cover glass to ensure the required polishing, in some embodiments, see Figure 1 As shown, a plurality of first through holes 11 are arranged in a divergent shape on the fixed plate 1; and a plurality of second through holes are arranged in a divergent shape on the connecting portion. In this way, the plurality of first through holes 11, the first structural member 2 with water absorption performance, and the plurality of second through holes form a plurality of delivery channels, so as to increase the amount of polishing liquid delivered to the polishing part and the cover glass, so that the polishing liquid can meet the requirements of polishing, and the divergent distribution can deliver the polishing liquid to different polishing parts and different positions of the cover glass more evenly, so as to ensure that the temperature of different positions of the cover glass is within the preset temperature range during polishing, and ensure the cleanliness of different positions of the cover glass after polishing, and at the same time, the divergent arrangement makes the polishing device have a beautiful visual effect.

[0042] In one example, a liquid feeding plate is provided on the polishing device, and a plurality of water feeding holes are provided on the liquid feeding plate in a divergent distribution. When the polishing device is connected to the polishing device, the plurality of first through holes 11 are connected to the plurality of water feeding holes in a one-to-one correspondence. In this way, when the polishing device is connected to the polishing device, the supply setting of the polishing liquid can be realized, making the operation convenient.

[0043] When the fixing plate 1 is provided with a first through hole 11, the connecting portion is provided with a second through hole, and the first structural member 2 is a structural member with water absorption performance, and the two ends of the first structural member 2 are respectively opposite to the first opening of the first through hole 11 and the second opening of the second through hole, in order to more quickly deliver the polishing liquid in the first through hole 11 to the polishing portion and the cover glass to ensure the required polishing, in some embodiments, the first structural member 2 is provided with a third through hole, and the openings at the two ends of the third through hole respectively correspond to the first opening of the first through hole 11 and the second opening of the second through hole. In this way, the polishing liquid in the first through hole 11 can be more quickly delivered to the polishing portion and the cover glass through the third through hole to ensure the required polishing.

[0044] In some embodiments, see Figure 1 As shown, a plurality of first through holes 11 are arranged in a divergent shape on the fixed plate 1; the number of second through holes is multiple, and they correspond to the multiple first through holes 11 one by one; the number of third through holes is multiple, and they correspond to the multiple first through holes 11 one by one. In this way, the multiple first through holes 11, the multiple second through holes and the multiple third through holes form multiple delivery channels, so that more polishing liquid can be quickly delivered to the polishing part and the cover glass, thereby meeting the polishing requirements, and the divergent distribution can deliver the polishing liquid to different polishing parts and different positions of the cover glass more evenly, so as to ensure that the temperature of different positions of the cover glass is within the preset temperature range during polishing, and ensure the cleanliness of different positions of the cover glass after polishing, and at the same time, the divergent arrangement makes the polishing device have a beautiful visual effect.

[0045] In some embodiments, the fixing plate 1 is provided with a first through hole 11; the connecting portion is provided with a second through hole; the first structural member 2 is a structural member without water absorption performance, and the first structural member 2 is provided with a third through hole, and the openings at both ends of the third through hole correspond to the first opening of the first through hole 11 and the second opening of the second through hole, respectively. Here, the first structural member 2 can be a high foam to have a first elasticity but no water absorption performance, and at the same time, the first through hole 11, the third through hole and the second through hole form a delivery channel to be able to provide polishing liquid to the polishing portion and the cover glass contacted by the polishing portion.

[0046] In the specific implementation of this embodiment, the plurality of first through holes 11 may be distributed in a divergent manner on the fixed plate 1, the plurality of second through holes correspond to the plurality of first through holes 11 one by one, and the plurality of third through holes correspond to the plurality of first through holes 11 one by one. In this way, the plurality of first through holes 11, the plurality of second through holes and the plurality of third through holes form a plurality of delivery channels, so that more polishing liquid can be quickly delivered to the polishing part and the cover glass, thereby meeting the requirements of polishing, and the divergent distribution can deliver the polishing liquid more evenly to different polishing parts and different positions of the cover glass, thereby ensuring that the temperature of different positions of the cover glass is within the preset temperature range during polishing, and ensuring the cleanliness of different positions of the cover glass after polishing, and the divergent arrangement makes the polishing device have a beautiful visual effect.

[0047] In some embodiments, see Figure 1 and Figure 2 As shown, a connection structure 12 is provided on the fixed plate 1 to enable the polishing device to be detachably fixed on the polishing equipment. In this way, the assembly and disassembly of the polishing device and the polishing equipment can be conveniently realized.

[0048] In one example, see Figure 1 and Figure 2 As shown, the fixed disk 1 is in the shape of a circular plate, and a plurality of connecting structures 12 in the form of slots are arranged on the circumferential side. In this way, a plurality of clips on the circumferential side of the liquid delivery disk of the polishing device can respectively extend into the plurality of slots to connect with the fixed disk 1, thereby connecting the polishing device to the polishing device. Subsequently, a force away from the slots can be applied to the clips to detach the clips from the slots, thereby detaching the polishing device from the polishing device.

[0049] In one example, the fixed plate 1 is in the shape of a circular plate, and a plurality of connecting structures 12 are arranged on the circumferential side. The connecting structure 12 is a first connecting hole with a threaded arrangement on the inner wall. In this way, a screw can pass through a second connecting hole on the circumferential side of the liquid delivery plate of the polishing device and be screwed to the first connecting hole, thereby connecting the polishing device to the polishing device. Subsequently, the screw can be removed to separate the polishing device from the polishing device.

[0050] In some embodiments, the hardness of the fixing plate 1 is greater than the hardness of any one of the first structural member 2 and the second structural member 3; or, see Figure 1 and Figure 2 As shown, the thickness of the first structural member 2 in the direction from the fixing plate 1 to the second structural member 3 is greater than the thickness of either the fixing plate 1 or the second structural member 3 .

[0051] The hardness of the fixed plate 1 is greater than the hardness of any one of the first structural member 2 and the second structural member 3. In this way, after the polishing device is connected to the polishing equipment, when the polishing equipment provides a high-speed polishing force, the deformation is small, so as to reduce the error between the actual polishing position and the preset polishing position, thereby improving the accuracy of the polishing position.

[0052] The thickness of the first structural member 2 from the fixed plate 1 to the second structural member 3 is greater than the thickness of either the fixed plate 1 or the second structural member 3. In this way, the first structural member 2 can produce sufficient deformation to adapt to a non-planar position with a greater degree of bending on the cover glass, such as a position with a greater degree of curvature, and provide a greater buffering force to the cover glass to better protect the cover glass. At the same time, the small thickness of the fixed plate 1 and the second structural member 3 can reduce the material used to reduce the manufacturing cost.

[0053] In some embodiments, see Figure 1 and Figure 2 As shown, the fixed plate 1, the first structural member 2 and the second structural member 3 are stacked in sequence, and the peripheral sides of the fixed plate 1, the first structural member 2 and the second structural member 3 are flush with each other. The stacking in sequence facilitates the manufacturing process by processing layer by layer, and the stacking and flushing make the polishing device visually beautiful.

[0054] For a specific example, see Figure 1 and Figure 2 As shown, the polishing device may include:

[0055] The fixing plate 1 is in the shape of a circular plate and made of PVC material with a hardness range of 85-95p and a thickness range of 25-40mm. A plurality of connecting structures 12 in the form of card slots are arranged on the peripheral side, and the fixing plate 1 is provided with a plurality of first through holes 11 distributed in a divergent shape;

[0056] The first structural member 2 is a sponge with a hardness range of 20-40p and a thickness range of 70-100mm. The first structural member 2 is connected to one side of the fixed disk 1, and the peripheral side is flush with the peripheral side of the fixed disk 1. The first structural member 2 is provided with a plurality of third through holes, and the plurality of third through holes correspond to the plurality of first through holes 11 one by one.

[0057] The second structural member 3 includes: a connecting portion and a plurality of polishing portions, the plurality of polishing portions are connected to the side of the first structural member 2 away from the fixed plate 1 through the connecting portion, the connecting portion and the plurality of polishing portions form a carpet structure, the connecting portion is a leather structural member on the carpet that is elastic and connected to a plurality of woolen threads, cloth strips or cotton strips, etc., the polishing portion is a cotton and linen fabric such as woolen threads, cloth strips or cotton strips connected to the connecting portion, and the length of the polishing portion can range from 10 to 30 mm. The peripheral side of the second structural member 3 is flush with the peripheral side of the first structural member 2.

[0058] The processing and polishing steps of the polishing device are: making a fixed plate 1 → cutting sponge and opening a third through hole to form a first structural member 2 → cutting a carpet and opening a second through hole to form a second structural member 3 → bonding the cut sponge to the fixed plate 1 → bonding the cut carpet to the sponge → connecting the slot on the side of the fixed plate 1 with the buckle of the polishing device → polishing the cover glass. The polished cover glass is inspected online by a quality inspector, the inspection method: visual inspection, inspection conditions: inspection under a three-wave lamp at 1000l ux, the inspection quantity is 6,300 pieces of cover glass, 5,985 pieces are good, the yield is 95.5%, the scratch defect accounts for 2.5%, and the polishing mark defect accounts for 2%.

[0059] According to statistics, when conventional polishing discs such as pig hair brush discs, leather grinding strip brush discs, resin fiber brush discs or mixed hair brush discs are working: a single machine polishes 300 pieces of cover glass per day, with a yield rate of 75%, scratches accounting for 15%, and poor polishing marks accounting for 10%; after using the polishing device of this embodiment: a single machine polishes 600 pieces of cover glass per day, with a yield rate of 95%, scratches accounting for 3%, and poor polishing marks accounting for 2%. It can be seen that the processing capacity efficiency is increased by 1 times, and the yield is increased by 20%.
