Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mobile phone middle frame polishing, in particular to a mobile phone middle frame polishing ring. Background Art
[0002] With the diversification of mobile phone designs, the shape of the mobile phone middle frame is becoming more and more complex. There are both right-angle frames and curved frames on the market. The traditional mobile phone middle frame grinding and polishing mainly uses grinding discs, which are limited to the grinding of right-angle frames and cannot meet the needs of curved frames. When using soft-based sandpaper for small arc grinding, there will be problems such as excessive coverage and insufficient sandpaper support, resulting in the vertical surface after grinding becoming an arc surface or edge collapse.
[0003] Therefore, a mobile phone middle frame grinding tool suitable for various shapes is needed to improve the grinding effect. Utility Model Content
[0004] The utility model provides a mobile phone middle frame polishing ring, which solves the problem of poor polishing effect of arc-shaped frames in the prior art.
[0005] The technical solution of the utility model is implemented as follows: a mobile phone middle frame polishing ring comprises a ring-shaped polishing layer, a buffer layer and a friction layer which are sequentially arranged from the outside to the inside.
[0006] Furthermore, the polishing layer, the buffer layer and the friction layer are bonded together by a glue layer.
[0007] Furthermore, the grinding layer is made of diamond emery cloth.
[0008] Furthermore, the polishing layer has a first interface, and the first interface is a bevel joint.
[0009] Furthermore, the angle between the first interface and the horizontal edge line of the polishing layer is 40°-70°.
[0010] Furthermore, the buffer layer is made of high-elastic sponge.
[0011] Furthermore, the hardness of the high-elastic sponge is 25°-35°, and the thickness of the high-elastic sponge is 4.5mm-5.5mm.
[0012] Furthermore, the buffer layer has a second interface, and the second interface is a large wave shape.
[0013] Furthermore, the first interface is located near the second interface.
[0014] Furthermore, the friction layer is made of flannel.
[0015] After adopting the above technical solution, the beneficial effect of the utility model is as follows: the mobile phone middle frame polishing ring in the utility model can process the vertical surface and arc angle as the angle changes by setting an annular sandpaper polishing layer and a sponge buffer layer. When polishing the arc surface, the sponge has certain support and covering properties to avoid interference with the 3D surface; when polishing the 3D vertical surface, it can be well connected with the arc surface. In addition, the interface design of the polishing ring optimizes the contact area and flatness, and improves the durability of the polishing ring and the polishing effect of the product.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] like Figure 1-4 As shown, the mobile phone middle frame polishing ring in the embodiment of the utility model includes a ring-shaped polishing layer 10, a buffer layer 20 and a friction layer 30 arranged in sequence from the outside to the inside, and the polishing layer 10, the buffer layer 20 and the friction layer 30 are bonded together with a glue layer.
[0024] The grinding layer 10 is made of diamond cloth. The grinding layer 10 has a first interface 11, which is beveled, and the angle between the first interface 11 and the horizontal edge line of the grinding layer 10 is 40°-70°. Compared with vertical splicing, the beveled first interface 11 has a larger contact area and is smoother. In the process of use, the instantaneous contact area is smaller, which is conducive to long-term use.
[0025] The buffer layer 20 uses a high-elastic sponge to ensure that it can rebound in time after polishing several products, thereby improving the service life and use efficiency. The hardness of the high-elastic sponge is 25°-35°, which can not only avoid the surface of the product being not polished cleanly due to insufficient coverage, but also prevent the sponge from being too soft and causing the sponge to be too strong in coverage, thereby causing the product to collapse and interfere with other surfaces. The thickness of the high-elastic sponge is 4.5mm-5.5mm, which can not only avoid the sponge thickness being too low and causing insufficient support, but also avoid the sponge being too thick and causing interference.
[0026] The buffer layer 20 has a second interface 21, and the second interface 21 is a large wave shape. Compared with the W-shaped interface, the large wave shape of the second interface 21 is not easy to be squeezed out during the grinding process, thereby ensuring the stability of use.
[0027] The first interface 11 is located near the second interface 21. The force release through the sponge gap of the buffer layer 20 effectively offsets the high point and insufficient coverage of the first interface 11 of the polishing layer 10, thereby avoiding premature wear due to high points, improving the durability of the polishing ring, and ensuring that the polished product is smooth and traceless.
[0028] The friction layer 30 is made of flannel to increase friction so that the grinding ring is not easy to fall off.
[0029] The mobile phone middle frame polishing ring in the utility model can process the vertical surface and arc angle as the angle changes by setting the annular sandpaper polishing layer 10 and the sponge buffer layer 20. When polishing the arc surface, the sponge has certain support and covering properties to avoid interference with the 3D surface; when polishing the 3D vertical surface, it can be well connected with the arc surface. In addition, the interface design of the polishing ring optimizes the contact area and flatness, improves the durability of the polishing ring and the polishing effect of the product.
[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
