The specific cleaning steps include: general cleaning, chemical cleaning, pure water cleaning and drying, the pull rope 16 is pulled regularly during the cleaning process to drive the two support shafts 13 to rotate in the same direction, and the aluminum oxide ceramic product supported on the support shaft can be deflected to adjust the posture, and then the covered part of the aluminum oxide ceramic product is exposed to contact with the cleaning liquid, thereby ensuring the cleaning effect. The jig, the loading frame 23 and the aluminum oxide ceramic product are transferred together into the cleaning tank for cleaning.

[0069] General cleaning, the product is sequentially cleaned by mixed acid, pure water, alkali solution, pure water, pure water flushing and drying. The aluminum oxide ceramic product is immersed in a mixed acid solution for 5 min, then immersed in a pure water overflow tank to wash away the residual mixed acid solution of the product, and then immersed in an 80℃ pH10-12 alkali solution containing a surfactant for ultrasonic cleaning for 10 min, and then immersed in a pure water overflow tank to wash away the residual alkali solution of the product. The product is flushed with pure water and dried with nitrogen.

[0070] Chemical cleaning, the product is sequentially cleaned by mixed acid, pure water, pure water flushing and drying. The aluminum oxide ceramic product is transferred to a mixed acid solution for cleaning for 20 min, and then immersed in a pure water overflow tank to wash away the residual mixed acid solution of the product. The product is flushed with pure water and dried with nitrogen.

[0071] Pure water washing, pure water ultrasonic cleaning, then ultrapure water cleaning, ultrapure water flushing and blowing dry. The alumina ceramic product is transferred to ultrapure water ultrasonic cleaning for 20 min, and then immersed in an ultrapure water overflow tank for cleaning. The product is flushed with ultrapure water and dried with nitrogen.

[0072] Drying, the dryer dries the product. The alumina ceramic product is loaded into a clean dryer, and dried at 100 DEG C for 40±5 min.

[0073] The alumina ceramic product is loaded on the alumina ceramic product cleaning fixture for cleaning, which is stable and reliable, and will not collide to cause damage during the cleaning process. After multiple cleaning procedures, the surface residues are cleaned well, and it is not easy to leave cleaning dead angles. In general cleaning, the alkali cleaning uses an alkaline solution containing a surfactant with a pH of 10-12, and ultrasonic cleaning at 75-85 DEG C. The product surface is dried with nitrogen to ensure the dryness and cleanliness of the product surface.

[0074] The above-described embodiments are only the preferred schemes of the present application, and do not limit the present application in any form. Other variations and modifications can be made without departing from the technical scheme recited in the claims.
