Abstract
Description
Technical Field
[0001] This utility model relates to the field of 3D glass processing technology, and more specifically, to a 3D glass polishing base. Background Technology
[0002] With the increasing use of 3D shapes in mobile phones, tablets, and wearable consumer electronics, the surface defects that appear after using 3D hot bending and cold carving processes make polishing the covers very difficult.
[0003] The current polishing base consists of the following: In mainstream polishing technology, the glass mounting consists of a base and a protective fixture. The base supports the glass cover, while the protective fixture protects the 3D area from over-polishing during the polishing process. Current solutions have the following problems: The protective fixture is made of TPU injection molding. During polishing, the polishing fluid and grinding disc grind the glass, generating heat. Under the combined effects of heat and the lateral force of the grinding disc, the TPU material deforms outwards, causing wear and tear, which renders the protective fixture ineffective. The bases are typically distributed individually on the worktable. The protective fixtures generally need to be replaced after 12 hours, resulting in high operating costs. The proportion of defective cover plates due to over-polishing caused by the protective fixture's deformation under heat and stress is around 5%. If the protective fixture's lifespan exceeds 12 hours, the proportion of defective cover plates increases proportionally.
[0004] To address this, this solution provides a 3D glass polishing base that can increase the service life of the protective fixture and reduce the proportion of over-polished glass covers. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a 3D glass polishing base, which can increase the service life of the protective fixture and reduce the proportion of over-polished glass covers.

[0007] In the above structure, the glass polishing position is rectangular and distributed in a cross shape on the top of the disc-shaped base body.
[0008] In the above structure, the protective fixture is rectangular, and its size is slightly larger than the glass polishing position.
[0009] In the above structure, the size of the baffle is adapted to the long side of the protective fixture.
[0010] In the above structure, the top of the disc-shaped base body is also provided with several mounting grooves. The mounting grooves are close to the four corners of each glass polishing position, and the distance between adjacent mounting grooves close to the long side of the glass polishing position is adapted to the length of the protective fixture, and the distance between adjacent mounting grooves close to the wide side of the glass polishing position is adapted to the width of the protective fixture.
[0011] In the above structure, a vacuum groove is also provided on the disc-shaped base body, and the vacuum groove is located at the center of each glass polishing position.
[0012] In the above structure, the disc-shaped base body is also provided with base fixing screw holes, which are rectangular and surround the vacuum groove.
[0013] The beneficial effects of this utility model are as follows: This solution sets a baffle on the base body, and the baffle is located on both sides of the protective fixture. This design can limit the deformation of the protective fixture due to heat and force during the glass cover polishing process, thereby reducing the defect rate caused by over-polishing of the cover and increasing the service life of the protective fixture. Therefore, this utility model can increase the service life of the protective fixture and reduce the defect rate of over-polishing of the glass cover. Attached Figure Description

[0015] Figure 2 This is a schematic diagram of the structure of the disc-shaped base body of a 3D glass polishing base according to the present invention. Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.
[0018] Reference Figure 1 and Figure 2 As shown, this utility model discloses a 3D glass polishing base, which includes a disc-shaped base body 1, several protective fixtures 2, and several baffles 3; the top surface of the disc-shaped base body 1 is provided with multiple glass polishing positions 4; the protective fixtures 2 are arranged around the glass polishing positions 4, and the protective fixtures 2 are detachably connected to the disc-shaped base body 1; the baffles 3 are fixedly connected to the disc-shaped base body 1, and the baffles 3 are located on both sides of the protective fixtures 2.
[0019] It should be noted that, in this embodiment, the disc-shaped base body 1 serves as a support platform, providing a stable polishing surface for the glass cover plate. The multi-polishing position 4 layout enables batch processing, improving polishing efficiency. The protective fixture 2 precisely defines the position of the glass cover plate, preventing displacement or collision during polishing. It also absorbs pressure or vibration from the polishing tools, preventing edge cracking. Furthermore, the detachable design of the protective fixture 2 and the disc-shaped base body 1 facilitates replacement of the protective fixture 2. The baffle 3 limits the deformation of the protective fixture 2 due to heat and stress during glass cover plate polishing, reducing the defect rate caused by over-polishing and extending the service life of the protective base. In specific implementation of this invention, firstly, the disc-shaped polishing base body is fixedly installed on the polishing worktable to ensure stability. Then, the 3D glass cover plate to be polished is placed on the disc-shaped base body. 1. On the top surface of the glass polishing position 4; next, install the protective fixture 2 to ensure that the protective fixture 2 can clamp and fix the 3D glass cover plate to prevent the 3D glass cover plate from shifting or colliding during the polishing process, and fix the protective fixture 2 to the disc-shaped base body 1; finally, use polishing tools (such as polishing wheels, grinding heads, etc.) to polish the glass surface evenly; during this process, the 3D glass polishing base absorbs vibration through the protective fixture 2, reduces the impact of the polishing tools on the glass edge, so as to avoid the 3D glass cover plate from shifting or breaking under polishing pressure. The baffle 3 restricts the deformation of the protective fixture 2 due to heat and force during the glass cover plate polishing process, so as to reduce the defect rate caused by over-polishing of the cover plate and increase the service life of the protective fixture 2 (the service life of the protective fixture 2 is increased to 72H, and the defect rate of over-polishing of the glass cover plate is reduced to 2%); therefore, this embodiment can increase the service life of the protective fixture 2 and reduce the defect rate of over-polishing of the glass cover plate.
[0020] Continue to refer to Figure 1 and Figure 2 As shown, the glass polishing position 4 is rectangular and distributed in a cross shape on the top of the disc-shaped base body 1.
[0021] It should be noted that in this embodiment, the glass polishing positions 4 are arranged in a cross shape and there are 6 of them on the top surface of the disc-shaped base body 1. This design makes full use of the top surface space of the disc-shaped base body 1 and designs as many glass polishing positions 4 as possible so that the 6 glass cover plates can be polished at the same time, thereby optimizing the polishing efficiency.
[0022] Reference Figure 1 As shown, the protective fixture 2 is rectangular, and its size is slightly larger than that of the glass polishing position 4.
[0023] It should be noted that, in this embodiment, the protective fixture 2 is designed to be slightly larger than the glass polishing position 4, which ensures that the protective fixture 2 can clamp and fix the 3D glass cover plate to prevent the 3D glass cover plate from shifting or colliding during the polishing process.
[0024] Reference Figure 1 and Figure 2 As shown, the size of the baffle 3 is adapted to the long side of the protective fixture 2.
[0025] It should be noted that, in this embodiment, the size of the baffle 3 is designed to match the long side of the protective fixture 2 in order to ensure that the baffle 3 can limit the deformation of the protective fixture 2 caused by heat and force during the glass cover polishing process, thereby reducing the defect rate caused by over-polishing of the glass cover and improving the service life of the protective base.
[0026] Continue to refer to Figure 1 and Figure 2 As shown, the top of the disc-shaped base body 1 is also provided with a number of mounting grooves 5. The mounting grooves 5 are close to the four corners of each glass polishing position 4, and the distance between adjacent mounting grooves 5 close to the long side of the glass polishing position 4 is adapted to the length of the protective fixture 2. The distance between adjacent mounting grooves 5 close to the wide side of the glass polishing position 4 is adapted to the width of the protective fixture 2.
[0027] It should be noted that, in this embodiment, the groove 5 is designed to accommodate the detachable connection between the protective fixture 2 and the disc-shaped base body 1. When the protective fixture 2 is installed with the disc-shaped base body 1, it is only necessary to snap the four corners of the protective fixture 2 into the groove 5. When it is necessary to remove the protective fixture 2, it is only necessary to pull the protective fixture 2 out of the groove 5. This design facilitates the replacement of the protective fixture 2.
[0028] Continue to refer to Figure 1 and Figure 2 As shown, the disc-shaped base body 1 is also provided with a vacuum groove 6, which is located at the center of each glass polishing position 4.
[0029] It should be noted that the vacuum groove 6 is designed to adsorb the glass cover plate onto the glass polishing position 4 of the disc-shaped base body 1, further ensuring that the glass cover plate does not shift during the polishing process.
[0030] Continue to refer to Figure 1 and Figure 2 As shown, the disc-shaped base body 1 is also provided with base fixing screw holes 7, which are rectangular and surround the vacuum groove 6.
[0031] It should be noted that, in this embodiment, the design of the fixing screw hole 7 is to fix the disc-shaped base body 1 to the polishing workbench with fixing screws so as to carry out the subsequent polishing process.
