AIS consists of a two-axis desktop robot (the Z and U axes are optional) and a PC-based vision system using the Cognex Vision Library as a platform. The camera is mounted on the desktop robot's y-axis, while the blister packs are moved along under the camera in the x-direction. Several inspections can be conducted for each nest. To simplify the entry of data per batch the system is equipped with a barcode scanner. The inspected data are compared against the set values and permissible tolerances. If a faulty product is detected, an alarm is triggered and quality assurance personnel remove the product for manual inspection. An added advantage of the system is that it ensures full 21 CFR part 11 compliance by tracking the results for each batch and integrating them for future reference. With the automation of the inspection process using vision, DePuy can be sure that the results being stored for each batch are reliable.
The standard PC has a 16bit 24V DC opto-coupled parallel interface, 2 RS-232 serial lines, Ethernet, and a printer port. Profibus interfaces, OPC Connectivity, ASI-Bus and additional specialized interfaces are optional.
The Cognex VisionPro software works in industries ranging from semiconductor and electronics to automotive to consumer products, pharmaceuticals and health care.
Future plans for expansion of the application may include surface inspection, print layout inspection, soldering point inspection, or code reading. The solution proposed here is easily adaptable for many other types of inspection and identification applications.
