Inspection Technology Identifies Surface Defects
- Saturday, 01 September 2012
An automated surface inspection technology identifies potential defects on a painted surface so that they can be remedied. The system provides a database so that the size, location, quality, and other aspects of production line defects can be tracked over time.The technology identifies dots and dust from 0.1 mm or greater on coated film, such as automobile bodies. It uses a series of LED lights, configured in stripes, and CCD cameras. The cameras provide images for analysis to a tracking system. If there is a defect, the angle of reflection from the lights produces greater brightness; the tracking software identifies flaws that pass a preset threshold.
