[0026] Embodiment two:

[0027] Please refer to the accompanying Figure 1 - attached Figure 3 and the accompanying Figure 6 , and on the basis of embodiment one, further obtained, the cooling mechanism 5 includes a cooling box 501 fixedly installed at the rear end of the surface of the machining table 1. The cooling box 501 is fixedly installed with a cooling pipe 503 at the bottom end of one side, and the pump body 502 is fixedly installed on the cooling pipe 503. One end of the cooling pipe 503 extends to the inside of the cooling box 501. The middle section of the cooling pipe 503 is fixedly installed in the inside of the fixed frame 2. The end of the cooling pipe 503 away from the cooling box 501 is fixedly installed with an atomizing nozzle 504. The direction of the atomizing nozzle 504 is the position of the polishing disc. The upper end of the cooling box 501 is provided with a liquid inlet 505.

[0028] The main component of the coolant is water, and additives such as lubricant and surfactant can be added. The lubricant can play a certain lubricating effect and improve the polishing efficiency. When designing and producing a regular earphone charging box, waterproof and dustproof factors are usually considered, and the internal circuit and electronic components are sealed. There is usually a sealing ring between the cover and the box body of the charging box, which can effectively prevent liquid from entering the inside. The charging interface and other parts of the earphone will also be protected by a sealing rubber ring or a sealing pad to prevent water from entering. When using the atomizing nozzle 504, the cooling liquid is usually applied to the surface of the charging box in the form of fine mist, which will not produce a large amount of water flow impact and will quickly play a cooling and lubricating role.

[0029] Specifically, during polishing, the pump body 502 is started to draw the cooling liquid in the cooling box 501 out through the cooling pipe 503, and then the atomizing nozzle 504 sprays uniformly on the polishing position.
