With the rise of globalization, outsourcing, and international joint ventures, there are increasingly more pharmaceutical and medical device companies with production facilities around the world. Today's production lines widely employ standardized inspection and identification solutions, significantly reducing total costs for investors. However, this also necessitates that suppliers be able to ship and support large-scale deployments, which means … the need for multiple video surveillance systems.
As one of the world's leading machine vision companies, Cognex has industry-leading visual inspection and recognition systems that provide manufacturers and equipment suppliers with greater security and help them cope more confidently with rapidly approaching regulatory deadlines!
Below , let me introduce some classic application cases of Cognex in the medical industry .
1In-Sight Vision System
Precisely position the injection bag and guide the robot to efficiently grasp it.
Suzhou Hanchuan Electromechanical Co., Ltd. ( hereinafter referred to as Hanchuan Electromechanical ) is a leading professional supplier of medical equipment, pharmaceutical products, and surgical peripheral products. Because the company's products are related to the personal safety of patients and medical staff, it requires production to ensure a zero error rate.
In the past, Hanchuan Electromechanical Company mostly used manual packaging for products such as infusion needles, needle sleeves, and infusion tubing. This was labor-intensive and prone to misplacement, which not only affected product quality but also resulted in low production efficiency. Therefore, the company decided to use robots on the production line, along with vision inspection equipment and automatic heat sealing machines, to achieve automated packaging and improve production automation and efficiency. However, the processing speed and accuracy were still not ideal.
By adopting the Cognex In-Sight vision system with PatMax tools, the robots on Hanchuan Electromechanical Company's production line have greatly improved the processing speed and automation of brine bag picking and placing, significantly increasing output and reducing human error.

It can efficiently solve the problem of rapid detection of labels on large-volume parenteral solutions.
Shandong Kelun Pharmaceutical Co., Ltd. ( hereinafter referred to as Kelun Pharmaceutical ) is mainly engaged in the production and manufacturing of large-volume injections, with an annual output of 300 million bottles of large-volume parenteral solutions. To ensure a 100% product qualification rate, Kelun Pharmaceutical implements a complex testing process covering visual inspection, label inspection, packaging, and inventory management.
Previously, the label inspection process for infusion bottles on the production line was entirely manual. Three inspectors worked at each station, and missed inspections were frequent, such as misaligned or skewed labels, and the work was physically demanding. Therefore, Kelun Pharmaceutical decided to adopt machine vision technology to solve problems related to label character matching and label tilt detection .
Later, Kelun Pharmaceutical adopted two Cognex In-Sight vision systems, along with Cognex touchscreens as the human-computer interaction interface. The In-Sight vision system lived up to expectations, helping Kelun Pharmaceutical achieve its technical transformation task of high-speed product label inspection on-site, and earning recognition and praise from the client and project engineers.

It has a wide range of tools for detecting defects in medical plastic bottles.
Beijing Aoxing Hengxun Packaging Technology Co., Ltd. ( hereinafter referred to as Aoxing Hengxun ) is dedicated to the pharmaceutical and life sciences industry. Since its establishment in 1991 , its products have been renowned in the industry for their high quality. The company's main businesses include the sales of advanced European and American pharmaceutical equipment and packaging machinery ; production technology, engineering design, project management, and EPC (Engineering, Procurement, and Construction) services ; and the research, development, production, and sales of pharmaceutical consumables.
In the past, medical plastic bottles produced by Aoxing Hengxun Company relied on manual inspection. In order to meet the strict inspection requirements, not only did it consume a lot of human resources, but the quality of sorting also varied.
By adopting the In-Sight vision system with its rich set of tools ( PatMax , Blob & ExtractHistogram ) , coupled with the meticulous attention to technical details by Cognex's technical engineers, Aoxing Hengxun has significantly improved its production efficiency in sorting and inspecting plastic bottles, saving labor costs and ensuring product quality.
