[0002] Dexamethasone acetate tablets are a pharmaceutical preparation. The main ingredient of dexamethasone acetate tablets is dexamethasone acetate, and its chemical name is 16α-methyl-11β,17α,21-trihydroxy-9α-fluoropregna-1,4-diene-3,20-dione 21-acetate. It is mainly used for the treatment of allergic and autoimmune inflammatory diseases.

[0003] In the process of producing dexamethasone acetate tablets, tablets that do not meet the quality standard requirements due to various reasons (such as equipment failure, raw material problems, operation errors, etc.) are collectively referred to as defective tablets. These tablets may have appearance defects, insufficient content, excessive impurities, etc. Therefore, they cannot be shipped as qualified products and usually need to be removed to ensure that the dexamethasone acetate tablets leaving the factory meet the quality standards and guarantee the safety and efficacy of patients' medications.

[0004] However, the existing methods for identifying and removing defective tablets in the production of dexamethasone acetate tablets mainly include manual or using machines to inspect the appearance of tablets and identify tablets with obvious defects. The manual method usually has low efficiency. For machine identification, although the identification efficiency is high, it can only identify, and then give an alarm prompt after identifying the defective tablets, and still requires manual removal, which has limitations.

[0005] Therefore, it is necessary to design a device for identifying and removing defective tablets in the production of dexamethasone acetate tablets to solve the above-mentioned problems. Content of the Utility Model
