Machine Vision Technology Application in Medical Field
In recent years, endless medical safety problems have concerned us. The quality testing in the field of medicine deserves our great attention. The traditional manual inspection is still widely used in China's pharmaceutical enterprises, but some objective and unavoidable disadvantages gradually appear, such as high investment of human labor, low efficiency, low accuracy, and frequent false and missed detection, so Machine vision technology with better efficiency will undoubtedly become the inevitable choice for the development of pharmaceutical enterprises in the future.
The advantages of machine vision technology make it widely applicable in the pharmaceutical industry. The detection of filling liquid level of liquid preparations, the detection of impurities in the bottle and the quality of closure, the detection of missing particles of blister drugs, and the OCR recognition of outer packaging characters of pharmaceutical products undoubtedly put forward more stringent requirements for detection accuracy, detection speed and detection quality.
Particle defect detection of blister drugs
Check whether the drug has defects such as, missing, fragments and so on. The camera vision system can be used to detect the appearance of drugs, comprehensively analyze the surface defect detection by counting and other algorithms, and quickly and accurately detect the defects and defects of tablet packaging and drug particles, so as to accurately separate the finished products and waste products, so as to ensure the quality of drugs.
Filling liquid level detection
The purpose of detecting the filling liquid of liquid preparation is to detect the liquid level and whether the bottle cap is correctly installed through the visual camera. When the machine vision technology accurately detects that the filling liquid level exceeds the set tolerance range, it will send a defective product signal to the system to eliminate the defective products.
OCR recognition of outer packaging characters of pharmaceutical products
According to relevant national regulations, the medical industry must indicate the product batch number, production date, validity period (or expiration period) and corresponding bar code information on the drug packaging, so that enterprises can establish a product tracking system and meet the requirements of enterprises to collect product information in real time. The machine vision system has excellent character recognition ability, and can accurately and quickly read the characters, bar codes and two-dimensional codes on various packaging materials.
After the completion of the above three medical detection systems, they can classify and count the missing and defect types of drug granules and capsules, connect with the enterprise intelligent detection system, analyze the detection data information and judge the equipment fault point, so as to optimize the detection system. Machine vision detection in pharmaceutical industry makes the detection process more simple, fast and accurate. Improve enterprise efficiency and save costs from all aspects.
