Technical Field

[0001] This utility model relates to the field of electronics manufacturing, and in particular to a grinding device for processing mobile phone casings. Background Technology

[0002] Polishing the phone casing is a crucial manufacturing step, designed to remove surface defects and optimize surface quality, laying a solid foundation for subsequent processes such as coating, painting, or anodizing. Whether done manually or mechanically, the goal is to ensure the phone casing has an excellent appearance and feel, thereby enhancing the user experience.

[0003] When polishing mobile phone casings, some debris is usually generated. However, existing mobile phone casing polishing equipment cannot automatically clean and collect the debris after polishing, which requires manual cleaning of the debris, increases the extra operation time, and reduces the overall production efficiency.

[0004] To address the existing problems, there is a need for a grinding device for mobile phone casing processing that can automatically clean up debris. Utility Model Content

[0005] To overcome the drawback of not being able to automatically clean and collect debris, this utility model provides a grinding device for processing mobile phone casings.

[0006] The technical implementation scheme of this utility model is as follows: A grinding device for processing mobile phone shells includes a frame, a moving component, a grinding head, an electric turntable, and placement blocks. The moving component is mounted on the frame, and the grinding head is mounted on the moving component. The electric turntable is mounted on the frame, and multiple placement blocks are evenly spaced on the electric turntable. The device also includes a connecting frame, a first electric push rod, a moving plate, a brush, a first mounting frame, a protective net, an exhaust fan, a connecting pipe, a connecting plate, a rotating shaft, a rotating plate, and a torsion spring. The connecting frame is connected to the frame, and the first electric push rods are symmetrically mounted on the top left and right sides of the connecting frame. A movable plate is connected between the telescopic ends of the two first electric push rods. Multiple brushes are evenly spaced on the movable plate. A first mounting frame is installed inside the connecting frame. A protective net is installed on the front side of the first mounting frame. Multiple exhaust fans are evenly spaced inside the first mounting frame. Connecting pipes are symmetrically connected to the rear side of the first mounting frame. Connecting plates are connected to the rear side of the two connecting pipes. Rotating shafts are rotatably connected inside the two connecting plates. A rotating plate is connected between the front sides of the two rotating shafts. The rotating plate contacts and engages with the two connecting pipes. Torsion springs are connected to the two rotating shafts and the corresponding connecting plates.

[0007] More preferably, it also includes a second mounting frame, a second electric push rod, and a push plate. The second mounting frame is mounted on the frame, and the second electric push rods are symmetrically mounted inside the second mounting frame. The telescopic ends of the two second electric push rods are connected to the push plate.

[0008] More preferably, it also includes a collection box, with the collection box placed inside the connecting box.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Example: A grinding device for processing mobile phone casings, such as... Figures 1-9As shown, the assembly includes a frame 1, a moving component 2, a grinding head 3, an electric turntable 4, a placement block 401, a connecting frame 5, a first electric push rod 6, a moving plate 7, a brush 8, a first mounting frame 9, a protective net 10, an exhaust fan 11, a connecting pipe 12, a connecting plate 13, a rotating shaft 14, a rotating plate 15, a torsion spring 16, a collection frame 17, a second mounting frame 18, a second electric push rod 19, a push plate 20, a guide plate 21, and an inclined plate 22. The moving component 2 is mounted on the frame 1, which can drive the grinding head 3 to move. The grinding head 3 is mounted on the moving component 2 and can grind the phone case. The body is polished. An electric turntable 4 is mounted on the frame 1. Multiple placement blocks 401 are evenly spaced on the electric turntable 4 for placing the phone case. A connecting frame 5 is connected to the frame 1. First electric push rods 6 are symmetrically mounted on the top left and right of the connecting frame 5. A moving plate 7 is connected between the telescopic ends of the two first electric push rods 6. Multiple brushes 8 are evenly spaced on the moving plate 7 to push and collect debris. A first mounting frame 9 is installed inside the connecting frame 5. A protective net 10 is installed on the front side of the first mounting frame 9 to filter larger impurities. Multiple exhaust fans 11 are evenly spaced inside the frame 9 to suck up debris. Connecting pipes 12 are symmetrically connected to the rear sides of the first mounting frame 9 for debris accumulation. Connecting plates 13 are connected to the rear sides of the two connecting pipes 12. Rotating shafts 14 are rotatably connected inside each connecting plate 13. A rotating plate 15 is connected between the front sides of the two rotating shafts 14, engaging with the two connecting pipes 12. Torsion springs 16 are connected to the two rotating shafts 14 and the corresponding connecting plates 13, allowing the rotating plates 15 to reset. A collection frame 17 is placed inside the connecting frame 5. The frame 1 is used to collect the polished mobile phone casings. A second mounting frame 18 is installed on the frame 1. The outer side of the second mounting frame 18 is provided with heat dissipation holes at even intervals to facilitate heat dissipation of the second electric push rod 19. The second electric push rod 19 is symmetrically installed inside the second mounting frame 18. The telescopic ends of the two second electric push rods 19 are connected to push plates 20, which can lift the mobile phone casings so that the staff can easily remove them. A guide plate 21 is installed on the inner rear wall of the first mounting frame 9. An inclined plate 22 is connected inside the connecting frame 5. When the exhaust fan 11 sucks in the debris, it can guide the debris.

[0026] When it's time to polish the phone casing, the worker first activates the two first electric push rods 6. The first electric push rods 6 extend and retract, moving the moving plate 7 and three brushes 8 forward. Once the first electric push rods 6 have reached their ends, they are deactivated. The worker then places the two phone casings onto the two placement blocks 401 on the left side. Next, the electric turntable 4 is activated and rotated 90 degrees clockwise. After the turntable 4 completes its rotation, it automatically shuts off, moving the two phone casings to the bottom position of the polishing head 3. At this point, the worker can activate the moving component 2 and the polishing head 3. The moving component 2 drives the polishing head 3 to polish the phone casings. While the polishing head 3 is polishing the phone casings, the worker again places the two phone casings onto the left side... After the grinding head 3 finishes grinding the two rear phone cases on the two placement blocks 401, the moving component 2 and the grinding head 3 are turned off. Then, the electric turntable 4 is restarted and rotated 90 degrees. The electric turntable 4 rotates the phone cases on the two rear placement blocks 401 to the position of the second mounting frame 18, and rotates the phone cases on the two left placement blocks 401 to the bottom of the grinding head 3. At this time, the grinding head 3 and the moving component 2 can be restarted to grind the second set of phone cases. At the same time, the operator can complete the loading step again. When it is necessary to remove the ground phone cases, the two second electric push rods 19 are activated. The two second electric push rods 19 drive the push plate 20 to move upward. During the upward movement of the push plate 20, the collection case is removed. The phone case is lifted up, allowing the operator to remove it. When the second electric push rod 19 extends to its end, it automatically retracts, resetting the push plate 20. This process can then be repeated to polish and disassemble the phone case. After polishing, the moving component 2, polishing head 3, and electric turntable 4 are turned off. When the operator needs to clean up debris from polishing, the two first electric push rods 6 and multiple exhaust fans 11 are activated. The first electric push rods 6 retract, moving the moving plate 7 and brush 8 backward. During the brush 8's movement, debris on the electric turntable 4 is pushed towards the connecting frame 5. The exhaust fans 11 use suction to draw the debris into the connecting frame 5. The debris passes through the protective net 10. Larger impurities are filtered out, and the sucked-in debris is blown onto guide plate 21, which guides the debris into connecting pipe 12. After the first electric push rod 6 retracts, it extends and retracts again, moving the three brushes 8 back to their original positions. Once the brushes 8 are in their original positions, two of the first electric push rods 6 are closed. Then, the electric turntable 4 is restarted and rotated 90 degrees. After the electric turntable 4 has rotated, it is closed. The above operation is repeated, with the first electric push rod 6 driving the brushes 8 to retract, causing the debris on the electric turntable 4 to be sucked into connecting pipe 12. By continuing to repeat the steps of rotating the electric turntable 4 and extending and retracting the first electric push rod 6, the debris on the electric turntable 4 can be gradually cleaned and collected. After the debris cleaning and collection is completed,When the electric turntable 4 and the first electric push rod 6 are turned off, and a certain amount of debris is collected in the connecting pipe 12, the weight of the debris will cause the rotating plate 15 to rotate along the rotating shaft 14. The torsion spring 16 will deform, and the debris will fall into the collection frame 17 for collection. When there is no debris on the rotating plate 15, the torsion spring 16 will no longer be compressed, and the torsion spring 16 will drive the rotating plate 15 to reset. Then, the worker can remove the collection frame 17.
