[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1-6As shown, a polishing device for processing mobile phone back covers comprises a main body 1. A telescopic assembly 2 is fixedly mounted in the middle of the upper end of the telescopic main body 1. A polishing disc assembly is mounted at the lower end of the telescopic assembly 2. A mounting disc 3 is positioned above the polishing disc assembly. The mounting disc 3 is fixedly connected to the telescopic assembly 2. A guard plate 4 is rotatably mounted on the inner side of the mounting disc 3. A slide groove 5 is provided on one side of the guard plate 4 through the mounting disc 3. When the back cover is polished, the telescopic assembly 2 is activated, driving the polishing disc below it to slowly move downward. As the telescopic assembly 2 moves downward, a zipper 7 is gradually pulled out from the mounting disc 3. At this time, the tension of the zipper 7 allows the four guard plates 4 to be pulled out one by one. When the polishing disc moves to the working position, all the guard plates 4 are pulled out, completely covering the back cover and the polishing disc assembly. This covering effect effectively prevents debris generated during the polishing process from flying around, thereby ensuring a clean and tidy work environment while protecting workers from injury. When the polishing disc finishes its work and resets, the zipper 7 will release the guard plate 4, and under the elastic force of the spring 6, the guard plate 4 can be smoothly retracted and wait for the next work to be opened;

[0024] Furthermore, an arc-shaped groove is provided on the inner side of the upper end of the guard plate 4, and a slide is provided on the outer side of the arc-shaped groove. The cooperation of the slide and the arc-shaped groove enables the guard plate 4 to be linked.

[0025] Furthermore, the outermost guard plate 4 is fixedly connected to the mounting plate 3 .

[0026] like Figure 2 and Figure 7As shown, there are two chutes 5, which are distributed up and down. A spring 6 is fixedly provided inside the chute 5, and a zipper 7 is also provided above the spring 6 in the chute 5. The upper end of the zipper 7 is fixedly connected to the top of the main body 1. A telescopic rod 8 is fixedly provided inside the main body 1 below the telescopic component 2, and there are four telescopic rods 8 evenly distributed with the telescopic component 2 as the center. A tray 9 is fixedly provided on the upper end of the telescopic rod 8. A button 10 is fixed inside the tray 9. The button 10 is located just below the guard plate 4, and the upper end of the button 10 is fixed. A pressure ring 11 is provided, which is also slidably connected to the tray 9. A dustproof strip 12 is fixedly installed on the inner surface of the tray 9 above the pressure ring 11. A support plate 13 is slidably installed in the middle of the tray 9. A push rod 14 is located directly below the support plate 13, and the lower end of the push rod 14 is fixedly connected to the main body 1. A bellows 15 is fixedly installed at the lower end of the tray 9, and the bellows 15 passes through the main body 1 and is connected to the external dust collection assembly. When the polishing plate moves downward, the telescopic rod 8 simultaneously lifts the tray 9 upward until the center support plate 13 falls. Subsequently, when the guard plate 4 moves to the working position, the button 10 can be pressed down through the pressure ring 11, thereby activating the external dust removal device. In this way, debris generated during the polishing process can be promptly removed. This not only further ensures the cleanliness of the workstation, but also prevents debris from affecting the quality of the workpiece, effectively improving the quality of the entire polishing operation and the comfort of the working environment, providing a strong guarantee for efficient and high-quality production operations.

[0027] Furthermore, using the pressing ring 11 to press the button 10 can prevent large particles that cannot be sucked away from entering and damaging the button 10 when the guard plate 4 is pressed or moved upward.

[0028] Furthermore, the dustproof strip 12 can remove debris adhering to the outer side of the guard plate 4 when the guard plate 4 is pressed down or moved upward, thereby further ensuring the cleanliness of the workstation.

[0029] Furthermore, the connection method between the button 10 and the external dust removal device is not limited, and both wired and wireless connections are possible.

[0030] Working Principle: When using this mobile phone back cover polishing device, first, when polishing the back cover, the telescopic assembly 2 activates, slowly moving the polishing disc below it downward. As the telescopic assembly 2 moves downward, the zipper 7 is gradually pulled out from the mounting disc 3. At this point, the tension of the zipper 7 allows the four guard plates 4 to be pulled out one by one. When the polishing disc moves to the working position, all the guard plates 4 are pulled out, completely covering the back cover and polishing assembly. This covering effectively prevents debris generated during the polishing process from flying around, ensuring a clean and tidy workstation environment while protecting workers from injury. When the polishing disc completes its work and returns to its original position, the zipper 7 releases the guard plates 4, which, under the elastic force of the spring 6, can be smoothly retracted, ready for the next operation. Finally, as the polishing disc descends, the telescopic rod 8 simultaneously lifts the tray 9 upward until the center support plate 13 falls. Subsequently, when the guard plate 4 moves to the working position, the button 10 can be pressed down via the pressure ring 11, thereby activating the external dust removal device. This allows debris generated during the polishing process to be promptly removed. This not only further ensures the cleanliness of the workstation, but also prevents debris from affecting the quality of the workpiece, thereby effectively improving the quality of the entire polishing operation and the comfort of the working environment, providing a strong guarantee for efficient and high-quality production operations. This is the working principle of the polishing device for processing mobile phone back covers.
