Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone component processing, and more specifically, to a high-precision polishing device for a mobile phone camera protection ring. Background Art

[0002] With the widespread use of smartphones, the protection of mobile phone cameras has become increasingly important. As an important component for protecting the camera, the smoothness and precision of the surface of the mobile phone camera protection ring have a direct impact on the camera's imaging effect and overall aesthetics.

[0003] Traditional polishing devices often use rigid fixation when polishing mobile phone camera protective rings, such as using a clamp to directly clamp the protective ring. However, the shapes and sizes of mobile phone camera protective rings vary to a certain extent, making rigid fixation difficult to fully adapt. Because the shape of the protective ring may vary slightly or the surface has a certain curvature, the rigid clamp may not fit tightly to the surface of the protective ring, making it prone to unstable fixation during the polishing process. This unstable fixation can cause the protective ring to shift, which in turn affects the accuracy of polishing. It may cause problems such as uneven polishing of the protective ring surface and substandard dimensional accuracy, thereby reducing product quality. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a high-precision polishing device for a mobile phone camera protection ring.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-3 , a high-precision polishing device for a mobile phone camera protection ring, comprising a support frame 1 and a support plate 2, the support plate 2 is fixedly connected to the inner side of the support frame 1, a polishing motor 3 is arranged on the inner side of the support frame 1, the output shaft of the polishing motor 3 is fixedly connected to the rotating shaft 4, and a polishing wheel 5 is fixedly installed on the bottom of the rotating shaft 4 by a screw, which is characterized in that: a moving adjustment mechanism 6 for driving the polishing motor 3 to move horizontally and vertically is arranged on the inner side of the support frame 1, and the moving adjustment mechanism 6 enables the polishing wheel 5 to be accurately positioned to the part of the mobile phone camera protection ring that needs to be polished, such as the outer side, upper side or lower side, and through horizontal and vertical fine-tuning, it can be ensured that the polishing wheel 5 accurately contacts and polishes these parts, thereby improving the polishing accuracy.

[0024] The top of the support plate 2 is rotatably connected to a support rod 7. A ring of support airbags 8 is embedded in the outer wall of the support rod 7. An air pump 9 is fixedly mounted on the outer wall of the support rod 7. A connecting tube 10 is connected to the support airbag 8 and connected to the air pump 9. Using the support airbag 8 to secure the mobile phone camera protection ring provides greater stability than traditional fixing methods. The support airbag 8 can adaptively adjust its shape based on the inner diameter of the protection ring, allowing it to fit snugly against the inner wall of the protection ring, whether it is circular, elliptical, or has a special curve. During the polishing process, the protection ring will not wobble or shift due to a loose fixation, thus improving polishing accuracy. Furthermore, because the support airbag 8 surrounds the outer wall of the support rod 7, the force applied to the inner wall of the protection ring by the support airbag 8 is evenly distributed when securing the protection ring. This prevents damage to the protection ring due to localized excessive force during the polishing process, ensuring the integrity of the protection ring. A rotary motor 13 is fixedly mounted on the support frame 1, and its output shaft is fixedly connected to the support rod 7. The rotating motor 13 is started, and the output shaft of the rotating motor 13 drives the support rod 7 to rotate, thereby driving the mobile phone camera protection ring fixed on the support rod 7 to rotate. The operator can easily adjust the protection ring to a suitable angle according to the needs of polishing.

[0025] The overall operation process of the above-mentioned polishing device is as follows:

[0026] The mobile phone camera protection ring is placed on the support rod 7. At this time, the support airbag 8 on the support rod 7 is in an initial uninflated state.

[0027] Then start the air pump 9, which inflates the support airbag 8 through the connecting tube 10. After the support airbag 8 is expanded, it can fit tightly against the inner wall of the mobile phone camera protection ring, thereby firmly supporting the protection ring on the support rod 7.

[0028] Then the movement adjustment mechanism 6 starts to work, adjusting the horizontal and vertical positions of the polishing motor 3 and the polishing wheel 4. The horizontal movement can adjust the horizontal position of the polishing wheel 5 relative to the protective ring, and the vertical movement can adjust the vertical distance between the polishing wheel 5 and the protective ring, thereby accurately positioning the polishing wheel 5 to the area to be polished.

[0029] Finally, the polishing motor 3 is activated, and its output shaft drives the rotating shaft 4 to rotate. The polishing wheel 5 at the bottom of the rotating shaft 4 rotates at high speed to polish the protective ring. Furthermore, the rotating motor 13 is activated, and its output shaft drives the support rod 7 to rotate. This in turn drives the mobile phone camera protective ring fixed to the support rod 7 to rotate, achieving adjustment of the polishing position.

[0030] Furthermore, the movable adjustment mechanism 6 includes a transverse cylinder 61 fixedly mounted on the inner side of the support frame 1, the cylinder rod end of the transverse cylinder 61 is fixedly connected to a movable block 62, the movable block 62 is slidably connected to the inner top wall of the support frame 1 through a slide groove, the bottom of the movable block 62 is fixedly connected to a vertical cylinder 63, and the cylinder rod end of the vertical cylinder 63 is fixedly connected to the top of the polishing motor 3. The transverse cylinder 61 and the vertical cylinder 63 work together. When polishing the protective ring of the mobile phone camera, the polishing motor 3 is first adjusted to the approximately vertical position of the protective ring by the vertical cylinder 63, and then the polishing motor 3 is adjusted to fit the surface of the protective ring to be polished by the transverse cylinder 61, thereby achieving precise polishing of different parts of the protective ring.

[0031] Among them, there are multiple support airbags 8, and the multiple support airbags 8 are equidistantly arranged from top to bottom, and two adjacent support airbags 8 are connected by a connecting tube 10. Multiple mobile phone protection rings can be installed at one time for polishing, and then removed after all polishing is completed, thereby saving time. The connecting tube 10 is a telescopic tube. During the inflation and deflation of the support airbag 8, the telescopic tube can automatically adjust its length according to the expansion and contraction of the airbag. A receiving groove 11 for accommodating the connecting tube 10 is provided on the outer wall of the support rod 7, and a limit block 12 is provided on the side of the receiving groove 11 close to the outer wall of the support rod 7. The design of the receiving groove 11 and the limit block 12 makes the appearance of the entire device more neat, reduces the external messy pipelines, and is conducive to avoiding interference between the connecting tube 10 and other components during the polishing process.

[0032] Furthermore, the outer surface of the support airbag 8 is provided with a wear-resistant, non-slip pad 14, which forms a ring-shaped structure when viewed from above. The presence of the wear-resistant, non-slip pad 14 increases friction between the support airbag 8 and the protective ring. A weighted iron block 15 is mounted on the bottom of the support frame 1. The lower surface of the weighted iron block 15 is glued with a striped non-slip pad to enhance the stability of the device.

[0033] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
