Automatic
In-line Blister Pack Inspection
Using the DEX™ X-ray Camera System
The Solution
Image Scan’s DEX™ x-ray camera system is well suited to
this application. It is specifically designed for inspection of smaller
items in production lines and is capable of producing twodimensional
or even threedimensional images. The 2D variant is used here and provides
image data to custom embedded image-processing software. A variety
of advanced software algorithms are employed to identify rapidly and
reliably any empty blisters giving fully automatic pass/fail decision
capability. Inspection rates of 400 blisters per second are readily
achieved. When used to inspect blister packs in their final packaging,
the system is sufficiently sensitive to check also for the presence
of the important product instruction leaflet.
