Visual Inspection Research And Application On Drugs Filling Production Line

With the rapid development of science and technology, industrial production processes became more and more minute. To deal with the complex products, manufacturers gradually stepped up the quality of the product links input for the products inspection. Visual detection technology is increasingly being applied in various fields. And it can substitute the manual for fully automated product testing and certification process, or even the entire production process control. In this paper, starting from the Visual Inspection Technology, detailed description of the visual detection technology in large-scale pharmaceutical production line automation applications. And focusing on filling Drugs surface defect detection algorithm. This paper is structured as follows:First, this paper studies the theory of machine vision technology, and analysises the basic principles of visual detection technology and the characteristics of the Visual Inspection Technology Research and development trends, and the actuality of machine vision inspection. This paper also analysises the inspection technology outlined in the industrial, agricultural, military, transportation, and the medicine Application of the status.Second, this paper analysises the filling drug production processes, including the large infusion of soft bags, plastic bottles and glass bottles large infusion of large infusion production process, and outlines the filling of pharmaceutical production equipment development trends. For the large pharmaceutical manufacturing automated production line visual inspection technologies, the paper focuses on the detection technology and equipment in the pharmaceutical production and online application status at home and abroad. And detailed analysises optical imaging and visual access to information such as key technologies. Design and development of the pharmaceutical production line of intelligent visual inspection platform.The focus of the test platform for mechanical and electrical control structure, access to visual information of the detailed analysis of the study were based on PC-based intelligent cameras and the visual access to information means. Based on the precision manufacturing production line access to visual information to the special requirements of a large number of visual information on the new access method. On the principle of defective sorting, outlined the main form of defective sorting, and the details of pharmaceutical production lines intelligent visual inspection of the defective sorting platform design ideas and ways to achieve.Finally, pharmaceutical products filling production line detection of specific requirements. This paper discusses the surface of the filling defect detection algorithm of drugs for image preprocessing. On the edge detection, image thresholding segmentation, template matching and image affine invariant feature research for filling drugs Image Detection and identification methods. Drugs aperture which focuses on defect detection, capping detection, liquid level detection and the production date code detection algorithm. OpenCV combined with the open-source characteristics. Achieve detection system software development.
