Quick vision measurement
Quick vision measurement
A Mitutoyo quick vision (QV) 202 non-contact measuring machine has improved the efficiency of the product inspection department at Bourns Electronics in Dunfermline, Fife. It has also helped to improve production rates and allows the company's inspection personnel to work on other continuous inspection projects.
Bourns Electronics manufactures sensors and control systems for automotive, military and commercial customers. Manufacture to tight tolerances is critical and inspection of components such as printed elements, plastic housings, metal shafts and bushings is undertaken on the QV system. It has meant that the company no longer has to rely on calipers, comparators and microscopes.
The Mitutoyo QV system was selected as having the best performance of all systems evaluated and for being competitively priced. The QV 202 is a bench top size CMM with a measuring range of 200mm square and 150mm vertical ideally suited to Bourns Electronics' delicate components which are placed on the measuring table by inspectors.
The 3D system has a measuring accuracy of (4+5L/11,000) microns and a speed of 12 metres/minute. It uses a combination of edge detection image analysis algorithms via a high resolution 380,000 pixel CCD camera with high quality optics and Mitutoyo's SRD measurement scales mounted to the moving table to achieve highly sophisticated and accurate component measurement. According to the component to be measured, Bourns Electronics can achieve up to 900 × magnification.
For Bourns Electronics the QV 202 system has speeded up the inspection process, freed up inspectors for other inspection tasks and contributed to an overall improvement in production rates. It has allowed the company to identify quickly in process machining problems, for example in set-ups, and enables operators to take corrective action based on reliable data.
