In the process of automatic packaging, human eyes can not continuously detect the mass-produced products, and the machine vision inspection system can just solve this problem. The advantages of visual inspection technology lie in the accurate and rapid measurement of some small size, shape matching, color identification, etc., which can effectively complete the product packaging inspection, correctly read the product packaging information, and strictly control the product quality.
Application of machine vision inspection in pharmaceutical packaging industry
Production process control: for example, the damaged particles are removed and the correct particles are passed normally to ensure that all the particles in the bubble cap are intact;
Quality control: for example, after the completion of filling, measure whether the filling reaches the baseline;
Identification of characters, bar codes and two-dimensional codes: read bar codes, two-dimensional matrix codes or printed characters, and verify label contents and correct orientation;
Production control: check whether the instructions in each kit are missing or the total quantity of drugs produced;
The requirements of pharmaceutical packaging industry are very high, it must meet the specified standards before it can be produced and marketed. The visual inspection system undoubtedly brings a surprise to the pharmaceutical industry. It can not only ensure the quality of drugs, but also eliminate unqualified products in time, so as to ensure high-quality products and comply with relevant laws and regulations.
Application of machine vision system in food、beer、beverage industry
Detection of the outer package of boxed food: to detect the outer package of the boxed food (including the detection of the damage of the outer package, the existence of the label, the existence of the production date, etc.);
Detection of liquid level and bottle cap defect of transparent bottled beverage: detect the liquid level of transparent bottled beverage to ensure the consistency of beverage filling;
Detect the bottle cap packaging and eliminate the defective products such as missing bottle cap and bottle cap skew;
Appearance inspection of pop-up beverage and canned food: inspect the quality, production date and serial number of pop-up can packaged beverage and canned food;
Detection of carton beverage outer packaging: to detect the outer packaging of carton beverage, such as whether the straw is present or not, and whether the jack is damaged;
Overall packaging counting: counting the overall packaging of bottled and boxed drinks to ensure the number of packages, etc.
From the above industry analysis, it can be seen that the detection contents of machine vision inspection system are mainly divided into outer packaging label and three phases, such as the detection of production batch number, production date and shelf life, as well as the detection of barcode on the outer packing box, and the accurate identification of the correctness and integrity of barcode or character printing.
The outstanding contribution of machine vision inspection is to help enterprises in the process of mass production and processing of parts assembly integrity, assembly dimension accuracy, parts processing accuracy, position, angle measurement, part identification, characteristics, character recognition and other real-time monitoring and testing.
