Application of Machine Vision System Solution in Pharmaceutical Blister Packaging

Blister packs, also known as blister packs, are one of the most popular and fast-growing forms of flexible packaging in the pharmaceutical industry today. They are also one of the main packaging forms for tablets, capsules, suppositories, and pills in China . In the production process of pharmaceutical blister packs, a series of flow operations such as stirring, dosing, pressure sealing, cutting, etc. are generally performed, which are prone to leakage, debris, and foreign matter. Therefore, how to find and eliminate the unqualified products caused by these phenomena in time is very important to guarantee the product quality.

Blister machine

At present, in the production process of aluminum-plastic blister packaging, manual selection method and weight detection method are generally used for product quality inspection. The manual selection method requires human eyes to constantly stare at the densely packed drugs on the assembly line, which is labor intensive, coupled with the on-site environmental noise and the reflection of the drug packaging itself, and the workers are prone to fatigue, which causes some unqualified products to be unselected in time. Therefore, the blister packaging industry urgently needs a fast and efficient automation solution to meet its increasing production efficiency and quality requirements.

Among all the automation solutions, machine vision is a more suitable method for use on blister machines. The defect detection technology of machine vision is widely used in industry. With the development of technology, modern optics is used as the basis. Modern inspection technologies including science and technology of optoelectronics, computer imaging, information processing, computer vision, etc.-machine vision-based image detection technology has gradually matured, and image detection technology and defect detection technology can be combined more completely. As a domestic supplier of machine vision software, hardware and system integration solutions, Wei Shi Imaging is an excellent representative of domestic machine vision technology. Beijing Kezhizhi combines its own solution with a well-known domestic blister machine manufacturer to provide users with solutions Demystifying the application of machine vision in pharmaceutical blister packaging.

Blister pack inspection

As shown in the figure above, with a large-area backlight source, equipped with a Gigabit industrial camera and a telecentric lens, real-time images of the medicine particles can be collected without stopping the line, and other environmental interference is filtered out, and then supplemented by the visual image Self-developed image processing software determines whether the integrity and quantity of medicine particles meet the requirements and gives real-time processing signals.

Blister packaging inspection system

As shown in the figure below, the detected pellets may have the following states: vacuoles, broken bubbles, defects, etc. These different processing results will be transmitted to the lower computer through the PLC for easy removal and recording.

Defect detection

Unlike traditional vision integration providers, Jingke Zhizhao has a huge inherent advantage in system construction, experimentation, after-sales service, and cost due to its integrated R & D and production advantages of cameras, lenses, light sources, and software.
