Engineers at Moritex have developed a new system that can be used to inspect a variety of different needle types and geometries fully automatically.
The Moritex system features three Basler (Ahrensburg, Germany) ace CCD cameras, lens optics, an LED lighting system and a diode laser for locating the needle that needs to be inspected.
The cameras capture images of a needle from three different angles, after which software measures its geometry and compares it a known good standard to enable any deviations to be detected.
According to Basler, leading Japanese medical device manufacturers are already successfully using the inspection system in the production of their needles.
More information on the design of the vision system is available on the Basler web site here.
