Description

Technical Field

[0001] The present invention relates to the technical field of drug detection, and in particular to a light inspection machine for inspecting the clarity of injections. Background Art

[0002] Injection refers to a sterile solution made of drugs after extraction, purification, and preparation, which is then put into ampoules for subcutaneous, intramuscular, and intravenous injection. It includes injection solution and sterile lyophilized powder injection. During the production process of injection, the insoluble matter, precipitate, or foreign matter in the injection is checked and controlled to prevent adverse reactions caused by the injection of foreign matter into the body.

[0003] In the inspection of injection bottles, most domestic pharmaceutical companies still use the original backward method of manual visual inspection, which is not accurate enough and has high labor intensity. At present, there are also light inspection machines, including light sources, back panels and visual cameras. The clarity of the injection is judged by visual cameras through image analysis and processing.

[0004] However, the existing light inspection machine cannot perform a series of processing processes on the injection bottle before testing. The cleanliness of the injection bottle surface will directly affect the test results and needs to be wiped manually. The injection liquid needs to be shaken manually before testing to reduce precipitation. The powder injection needs to be manually injected with solvent into the bottle and shaken to dissolve before testing. This affects the light inspection efficiency when there are multiple bottles.
