[0002] A diaphragm refers to a thin film or membrane that can respond to sound waves, air currents or other vibrations. It is an important acoustic component widely used in devices such as speakers, microphones and headphones. When sound waves act on the diaphragm, it will generate corresponding vibrations, thereby converting sound waves into electrical signals or converting electrical signals into sound waves. After the diaphragm is cured and formed, a surface treatment device is required to finely polish and buff the surface of the diaphragm through a polishing wheel to improve the surface smoothness, reduce defects and improve the sound quality performance of the diaphragm, so that the subsequent coating treatment and quality inspection can be carried out more smoothly. However, the existing surface treatment device needs to manually clean the placement plate after polishing, which increases the workload of the operator, reduces the polishing efficiency of the surface treatment device, and the placement plate can only place diaphragms of a fixed model and cannot polish diaphragms of multiple models, which has limitations.

[0029] Working principle: During the use of the surface treatment device, first, the diaphragm needs to be placed on the groove corresponding to its diameter, and different models of placing plates 11 can be customized to achieve the purpose of polishing diaphragms of different models simultaneously, so that the surface treatment device can adapt to different order requirements. Then, the second motor 12 drives the threaded rod 13 to rotate, causing the threaded rod 13 to drive the placing plate 11 to move below the fixed frame 4. Next, the water pump 15 pumps the polishing liquid in the liquid storage tank 14 and transports it to the delivery pipe 16, and the polishing liquid is transported to the nozzle 17 through the delivery pipe 16. Subsequently, the polishing liquid is sprayed on the diaphragm through the nozzle 17. Then, the placing plate 11 can be continuously moved so that the placing plate 11 moves below the polishing wheel 10. Next, the hydraulic cylinder 5 drives the support plate 6 and the connecting plate 7 to move, and the connecting plate 7 drives the fixed seat 9 and the polishing wheel 10 to move above the diaphragm. Subsequently, the first motor 8 drives the fixed seat 9 and the polishing wheel 10 to rotate, causing the polishing wheel 10 to grind and polish the surface of the diaphragm. The debris generated during the polishing process will fall into the aggregate box 2 from the leakage holes 27 on the placing plate 11 through the leakage net 18. After the diaphragm is polished, the placing plate 11 needs to be moved away from the polishing wheel 10. Then, the debris on the surface of the diaphragm is scraped off by the soft brush 21, and the debris falls into the aggregate box 2 through the leakage holes 27 and the leakage net 18 through the guiding groove 26. Then, the cleaned diaphragm can be taken out, and the placing plate 11 is moved back to its original position to polish the next batch of diaphragms, realizing the automatic cleaning of the surface treatment device and improving the polishing efficiency of the surface treatment device. When the soft brush 21 is damaged, the mounting frame 20 needs to be replaced. By pulling the pull rod 25, the pull rod 25 drives the limit block 23 to move away from the limit hole 22 and compresses the first spring 24. Subsequently, the mounting frame 20 can be removed from the insertion rod 19. Then, pull the pull rod 25 on the newly installed mounting frame 20 and insert the mounting frame 20 into the insertion rod 19. Then, release the pull rod 25, and the reset of the first spring 24 drives the limit block 23 to insert into the limit hole 22, so that the limit block 23 and the insertion rod 19 complete the horizontal and vertical limits of the mounting frame 20, thus completing the replacement of the mounting frame 20, providing convenience for the replacement of the mounting frame 20. When the polishing wheel 10 is damaged and needs to be replaced, the rotating block 34 needs to be rotated away from the convex block 32. Subsequently, pull the connecting rod 31, causing the connecting rod 31 to drive the convex block 32 to move to a position away from the insertion block 29 and compress the second spring 33. Then, remove the polishing wheel 10 and insert the insertion block 29 on the new polishing wheel 10 into the fixed seat 9. Then, release the connecting rod 31, so that the reset of the second spring 33 drives the connecting rod 31 to insert into the insertion block 29 and drives the convex block 32 to insert into the fixed block 28. Subsequently, fix the rotating block 34 on the convex block 32, thus completing the replacement work of the polishing wheel 10, providing convenience for the maintenance of the surface treatment device.
