Automatic Visual Inspection System (AVI)
Trust the industry experts when you need vision inspection to guarantee product quality and safety. Read more below.
Automatic Visual Inspection is the combination of Machine Vision technology with Computer Vision science applied to the industrial sector. With reference to the pharmaceutical industry, the visual inspection technology is based on automated cameras and on complex vision algorithms that determine if the container is fit to comply with given standards by detecting:
Automatic Visual Inspection is a mandatory practice for injectable manufacturers to guarantee both quality and patient safety. The finished products must be inspected by a visual inspection machine to identify and reject visible foreign matter contaminated parenteral containers and units displaying defects that could potentially affect product quality.
The inspection and detection of foreign particulate matter (FPM) is critical for quality control in powders, liquids, and lyophilized parenteral products used to cure patients. Machine vision inspection systems are configured to detect extraneous particles such as:
The international regulations for Visual Inspection are laid out in the following protocols:
For each inspected container, a collection of product images in sequence at 360° is acquired using high resolution cameras under designed illuminating conditions. Defects on the package are identified and/or measured by dedicated image processing algorithms and the package is classified as conforming or non-conforming accordingly. Non-conforming packages are automatically rejected. In case of detection of Foreign Particulate Matter (FPM) with liquid content: the container is first put into motion, then stopped, followed by the acquisition of product images by high-resolution cameras that record a series of images. With powder or lyophilized content, the container is put into motion and cameras record a series of images, in sequence, at different moments during rotation.
Finally, custom inspection can be provided too with each specific product peculiarity. Bonfiglioli Engineering’s AVI systems can detect:
