The importance of machine vision technology in pharmaceutical industry

Food safety matters a great deal while pharmaceutical safety is a matter of life and death. Pharmaceutical detection is intended to prevent unqualified pharmaceuticals going into the market and guarantee pharmaceutical safety. Pharmaceutical detection involves multiple respects-pharmaceutical quality, composition, adverse drug reaction, routine detection, physico-chemical detection, pharmaceutical safety and pharmaceutical defect, etc. The application of pharmaceutical detection equipment will save traditional detection methods by eyes, nose and hand, delivering a more scientific and precise result. So the use of advanced detection equipment is meaningful for pharmaceutical detection.
The detection result is a key performance indicator for pharmaceutical detection equipment as well as the core competitiveness of equipment. So pharmaceutical detection equipment manufacturers need to boost technological R&D to make it easier to use, faster and more precise. Thanks to continuous development of science and technology, current pharmaceutical detection equipment has technologically improved a lot. For example, dedicated metal detector for pills developed by Shanghai Gaojing Detection Technology Co., Ltd. has two operating frequencies, so appropriate frequency will be automatically chosen according to product information; it adopts LCD touch screen control, realizing button-free operation; with self-learning, the detector store the information of 100 products; as it is highly sensitive to foreign bodies, it is suitable for detecting metal foreign bodies in tablets and capsules.
With rising demands for higher-quality pharmaceuticals, enterprises also require more advanced pharmaceutical detection equipment. Currently, enterprises are vying to eliminate any possible slight defect. Sometimes, it is impossible for human eyes to quickly measure micro sizes, match shapes and identify colors in a continuous and stable manner, even physical quantity sensor fails to do that. Then people begin to bring into the robot vision technology the speediness, reliability and repeatability of the computer.
Food and medicine are closely related to human health. If pharmaceutical quality threatened human life, it would be disastrous. So all pharmaceutical firms, especially the world-renowned ones attach great importance to the whole production process of pharmaceuticals and later packaging process. Machine vision technology is vitally useful in the production and packaging process of food and medicine, ranging from blister packaging, liquid bottling to sealing, labeling, marking to box detection.
With the state’s stricter supervision over pharmaceutical safety and unannounced inspections, pharmaceutical detection equipment will embrace huge opportunity. Enterprises should seize the chance, scale up technological strength and further increase detection efficiency to make the equipment irreplaceable in pharmaceutical detection. Under this circumstance, automation has become an inevitable trend for pharmaceutical machine industry, so pharmaceutical detection equipment also needs to be automated and intelligent for more precise and efficient operation.

Brief Description of Inspection System in Blister Machine
The inspection system in Blister Machine is equipped with a high speed, high resolution color camera. The inspection system can detect the smallest deflections at full production speed.
It is suitable for Blister Packaging Machine with intermittent or continuous web movements. All form and type of blister products can be inspected such as various types of tablets, hard / soft gelatin capsules, etc. packed in transparent, opaque, colored PVC foil and Aluminum foil.
Blister Machine Inspection System can detect the following situations:
> Surface of the Product
> Missing Product (Empty Pocket)
> Empty Blister
> Form of Product (Crushed, Powdered or Solid)
> Foreign Objects (Fragments)
> Unwanted Product or Fragment outside the Pocket
> Incorrect positioning of the Product
> Color of the Product (Correct or Wrong product in the Blister)
Blister Machine Inspection System Characteristics:
High resolution translates into detecting defects of size, shape and dimensions. This enables precise control over the quality of the product. Even minute black spots on tablets / capsules can be detected.
The state-of-the-art color recognition capability assures right product goes in the correct blister. Even shade variations are easily detected by the system.
Sequential Teach: The vision system learns from a sequence of multiple images to obtain the best tolerance settings and compensate for runtime variations. Intelligent software significantly reduces the teach time by auto extraction of information.
The software can be customized rapidly for individual customer needs and personalized report generation is also a possibility.
Web connectivity – Capable of Remote training, assistance and monitoring over the Internet.
Security: Different access levels for operator, supervisor and JEKSON are enabled.
Once the system has learned the new blister product, it is stored and validated. Afterwards, all the operator has to do is to select the correct product to start the inspection run. A special calibration procedure ensures that the validated configurations stay memorized, even if crucial parts are replaced.
The system considers every blister as ‘bad’ until proven good. This means that a complete and rigorous procedure has to be followed before a blister can be considered ‘good’. The system keeps records of the number of inspected blisters as well as the nature of the detected mistakes and the number of times they appear.
High resolution – megapixel color camera
Fire Wire technology for high speed communication
Automatic adjustment of all camera settings via the software
Low distortion lens provides high quality images.
High-density LED array lights provide uniform lighting over the entire blister width
Temperature compensation and heat sinking mechanism enables reliable and consistent light throughout life.
Expandable input and output module are easy to integrate and communicate with the machines programmable controls and rejection systems.
