Picture processing Automation with vision

June 26, 2014 6:13 am

 Automation solutions frequently require machine vision systems in order to perform inspection, control and guidance tasks at levels of speed, precision and reliability that far exceed human capabilities. Augmenting production lines with vision systems is a cost-effective way to speed up production while eliminating errors and improving quality. The new In-Sight 7000 series from Cognex now provides support for the deterministic Ethernet POWERLINK protocol.  
Vision systems are an essential component of any manufacturing process involving inspection, measurement, identification and guidance. One way they are used is to identify flaws in vacuum cleaner components and verify their completeness, positioning and functional dimensions following assembly.  
Immediate detection of defects with vision systems The part being inspected is placed on the carrier and rotated through a series of four different orientations. Parts that pass this inspection continue on for further processing. If any defects are identified, the part is rejected and an error report is generated; the defective part is then assigned to one of a number of uniquely coded defect classes. If necessary, images of defective parts can be saved for later evaluation.
The system inspects twelve measurement points on each component, each hardly perceptible to the human eye. A manual inspector wouldn’t stand a chance. The In-Sight camera can quickly recognize the tip of a metal spring, even when it only peers out from behind a plastic component by a few tenths of a millimetre. This level of inspection not only weeds out defects, it also ensures the high quality and long lifespan that help brand name products compete with cheap imitators.
