[0024] A scraper strip 30101 is provided at the part where the partition cover 301 and the outer side of the protective cover 3 are fitted.

[0025] It also includes a guide piece 302 , which is fixedly connected to the left front portion of the cleaning cover 4 ; the guide piece 302 is located in front of the avoidance groove 4002 .

[0026] Each air outlet 4001 is inclined toward the protective cover 3 , which is beneficial to enhancing the blowing effect on the polishing liquid droplets and reducing the adhesion of the polishing liquid droplets to the protective cover 3 .

[0027] When the camera is performing observation work inside the polishing machine, the metal particles and polishing liquid splashed during the polishing process are easy to accumulate on the protective cover 3, affecting the normal observation work of the camera module 2; for this reason, when the camera is performing observation work, based on looking from top to bottom, the DD motor 101 is controlled to drive the protective cover 3 to rotate counterclockwise on the outer shell 1, so that the protective cover 3 drives the impurities adhered to it from the avoidance groove 4002 into the cleaning cover 4, and then the external water circulation equipment is controlled to transport the water flow through the water inlet pipe 102 to the water cavity 1002, and then the water cavity 1002 is sprayed to the outside of the protective cover 3 through the water nozzle 1003 to flush the impurities attached to its surface to the bottom of the cleaning cover 4, and at the same time, the sewage at the bottom of the cleaning cover 4 is sucked and recovered through the suction pipe 103, and the filter screen and filtering and purification mechanism in the external water circulation equipment are used to intercept the polishing liquid and metal particles, and the clean The transformed water flow is pumped back into the water inlet pipe 102 to form a closed-loop cleaning cycle. It should be noted that the DD motor 101 drives the protective cover 3 to rotate at a relatively slow speed, so that the water flow out of the water nozzle 1003 can fully flush and clean the outside of the protective cover 3; in this way, the present invention ensures that the part of the protective cover 3 facing the shooting surface of the camera module 2 is always kept clean by making the protective cover 3 rotate continuously and using the water flow to flush and clean the impurities adhered thereto, thereby avoiding interference with the normal observation function of the camera module 2 due to the accumulation of impurities, and ensuring the stable observation effect of the camera when working inside the polishing machine. At the same time, by controlling the water delivery method of continuously flowing through the water cavity 1002, the circulating water flow can effectively absorb and take away the heat generated by the electronic components inside the heat dissipation cavity 1001 when working, thereby ensuring the stable operation of the camera in a high-temperature working environment.

[0028] During the operation of the camera, an external air pump delivers external airflow into the heat dissipation cavity 1001 through the spiral air delivery pipe 201. Since the air delivery pipe 201 runs through the water cavity 1002, the airflow will be cooled by the circulating water flow in the water cavity 1002 when it is transported in the air delivery pipe 201, so that the temperature of the airflow finally entering the heat dissipation cavity 1001 is reduced, thereby greatly improving the heat dissipation effect on the electronic components in the cavity, that is, the heat is taken away by water cooling and air flow circulation, further ensuring the stable operation of the camera in a high temperature environment. Note that the heat dissipation airflow flowing into the heat dissipation cavity 1001 is directedly discharged to the outer surface of the cleaned protective cover 3 through the water shield 202, and the moisture remaining on the surface of the protective cover 3 is air-dried, effectively avoiding the influence of residual water stains on the observation clarity of the camera module 2. At the same time, the airflow after the protective cover 3 is air-dried is blown out from the avoidance groove 4002, and the polishing liquid droplets generated during polishing are blown away from the protective cover 3, thereby reducing the adhesion of the polishing liquid droplets to the protective cover 3, which is beneficial to reduce the cleaning pressure on the protective cover 3.

[0029] It is also taken into consideration that during the polishing process, hard metal particles flying at high speeds hit the protective cover 3, which may easily form damaged white spots on the protective cover 3, affecting the normal observation of the camera module 2. The traditional solution requires that the damaged protective cover 3 be completely removed from the outer shell 1 and replaced with a new one. Although the observation function can be temporarily restored, the polishing operation must be interrupted during the replacement process to ensure operational safety. At the same time, due to the narrow space structure inside the polishing machine, the removal and installation process of the protective cover 3 is complicated and time-consuming, which significantly affects the polishing efficiency. Therefore, when the DD motor 101 drives the protective cover 3 with white spots to pass through the water nozzle 1003 to complete the cleaning, the heat dissipation airflow blown out from the water shield 202 is used to air-dry the white spot area on the protective cover 3. As the protective cover 3 continues to rotate and contacts the rubber pad 6, when the protective cover 3 rotates into the repair cavity 5001, the inside of the repair cavity 5001 The transparent filler of the part penetrates into the white spots on the protective cover 3. Since the refractive index of the transparent filler is similar to that of the base material of the protective cover 3, after the transparent filler penetrates into the white spots, the light scattering of the filling interface is reduced to less than 5% of the original value, thereby restoring the light transmittance uniformity of the protective cover 3 and repairing the white spots on the protective cover 3. While ensuring the normal observation effect of the camera module 2, there is no need for staff to disassemble and replace the protective cover 3, thereby ensuring the normal progress of the polishing work. The scraping part 6001 scrapes off the excess filler on the smooth surface of the protective cover 3 that passes through the repair area, and cooperates with the elastic sealing effect of the rubber pad 6 to doubly ensure that the filler is only located in the white spot defect, prevent the filler from leaking, and avoid affecting the observation effect of the camera module 2. When the filler needs to be supplemented or replaced, the sealing valve 5003 can be opened to conveniently supplement or replace the filler in the storage box 5.

[0030] When repairing the white dots on the protective cover 3 in the storage box 5, the airflow in the heat dissipation cavity 1001 is transported to the upper part of the storage cavity 5002 through the transfer pipe 7, so that the upper part of the storage cavity 5002 maintains a positive pressure environment, and the heat insulation plate 8 is squeezed downward, and the filler in the storage cavity 5002 is pressed into the repair cavity 5001. While ensuring that the filler in the repair cavity 5001 is always sufficient, the positive pressure is used to accelerate the infiltration effect of the filler on the white dots on the protective cover 3, thereby enhancing the repair effect on the white dots on the protective cover 3. At the same time, since both the storage box 5 and the heat insulation plate 8 are made of heat-insulating materials, the filler in the storage box 5 can be prevented from being affected by the external high temperature, and the filler in the storage box 5 can be prevented from sticking and solidifying due to the high temperature.

[0031] It is also considered that when the airflow discharged from the water baffle 202 dries the protective cover 3, the heat dissipation airflow is likely to blow the cleaning water flow out from the gap between the front side of the cleaning cover 4 and the protective cover 3, causing the risk of water leakage into the polishing machine tool. Therefore, by arranging a partition cover 301 between the water spray port 1003 and the water baffle 202, the movement paths of the heat dissipation airflow and the cleaning water flow are completely separated, and the heat dissipation airflow is guided to flow along the dedicated channel between the partition cover 301 and the cleaning cover 4, and finally is directionally sprayed to the front side of the protective cover 3 through the air outlet 4001, which not only ensures the drying effect but also completely blocks the interference of the airflow on the cleaning water flow, effectively preventing the polishing process pollution problem caused by liquid leakage. At the same time, by setting the air outlet 4001 to be inclined towards the front side of the protective cover 3 and guiding the heat dissipation airflow blown out from the left avoidance groove 4002 through the guiding piece 302, it is beneficial to blow the airflow towards the middle part of the front side of the protective cover 3, blow the polishing liquid droplets in the direction away from the protective cover 3, reduce the existence of the blowing blind area, and enhance the blowing effect on the polishing liquid droplets.

[0032] When the water spray port 1003 flushes and cleans the impurities adhered to the outside of the protective cover 3, the scraping strip 30101 scrapes the impurities still adhered to the protective cover 3 after flushing, enhancing the cleaning effect on the protective cover 3, and at the same time preventing the impurities from entering the repair cavity 5001 and contaminating the filler, and avoiding the reduction of the repair effect on the white dots on the protective cover 3.

[0033] Embodiment 2: On the basis of Embodiment 1, as Figure 5 and Figure 7 shown, it further includes heat dissipation fins 401; a plurality of heat dissipation fins 401 are fixedly connected in the water cavity 1002; the heat dissipation fins 401 are made of heat-conducting materials.

[0034] When water continuously flows through the water cavity 1002 to dissipate heat from the internal electronic components of the heat dissipation cavity 1001, by arranging a heat sink 401 in the water cavity 1002, the contact area between the outside of the heat dissipation cavity 1001 and the water flow in the water cavity 1002 is increased, the heat exchange effect between the outside of the heat dissipation cavity 1001 and the water flow is enhanced, and then the heat absorption effect on the heat in the heat dissipation cavity 1001 is enhanced, thereby improving the heat dissipation effect on the camera.

[0035] Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that various changes or modifications can be made to the present invention without departing from the principle and spirit scope of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present invention, and the scope of protection is defined by the content of the claims.
