s5: after the whole coating of the shell plate is finished, the coating brush (111) is taken out to be cleaned by using the cleaning mechanism (5), when the cleaning mechanism is used, the rotating plate (504) is stepped down, the other end of the rotating plate (504) is tilted, the cylindrical rod (506) is lifted up, the sliding block (507) and the bending plate (505) synchronously move upwards along with the rotating plate, the bending plate (505) can gradually contact with the coating brush (111) in the upward moving process, the coating brush (111) is lifted up, when the coating brush (111) is separated from the first limiting sliding groove (108), the coating brush (111) falls onto the cleaning roller (508) in the box body (501) along the bending plate (505), the cleaning roller (508) rotates to clean the coating brush (111), the rotating plate (504) is loosened, and the spring (503) drives the rotating plate (504) to return to the initial position.
