Application of machine vision system in medicine bottle filling production line

With the rapid development of science and technology, the industrial production process has been further refined, and products have become more and more complex. Manufacturers have gradually increased their investment in product quality testing. New technologies have been applied to quality inspection in different industries. Visual inspection technology is one of the representative inspection methods. It is increasingly being used in various fields to replace the human eye for fully automatic product inspection, process verification, and even automatic control of the entire production process. This article takes a real representative example of the visual image, that is, the application of the surface defect detection of filling drugs as an example, to show the reader the composition and characteristics of a typical automated vision system.

Traditional drug filling testing methods have many shortcomings, such as unstable test results, limited product testing range, low production efficiency, and high cost. Visual inspection methods effectively solve these problems. A typical defect detection system for a filled pharmaceutical product includes an industrial camera, an industrial lens, a set of processing software, and a set of IO communication equipment. Among similar projects handled by Wei Shi Imaging, the MV-EM / E series cameras are used more and have better stability, especially the 200W, 500W CCD and 1400W CMOS cameras are the star products used in this industry. As for the lens, it is mentioned that more is a bi-telecentric lens. Ordinary optical lenses have varying magnifications due to changes in working distance and limited depth of field. There are certain disadvantages when detecting surface defects. Telecentric lenses can be very good due to their own parallel light design. Solve these problems.

Compared with the human eye, the advantages of visual inspection are obvious. Because machine vision systems can quickly obtain a large amount of information, they are easy to process automatically, and it is easy to integrate with design information and processing control information. Therefore, in the modern automated production process, machine vision systems are commonly used in areas such as working condition monitoring, finished product inspection, and quality control, which provide important technical guarantees for product quality control and reliable and stable operation of the system.
