A Korean manufacturer of construction equipment is using optical character recognition to ensure quality control of its heavy industrial machinery.
Characters are engraved directly on the surface of the components, to provide unique information about the part. The Cognex DVT530 vision system was chosen to read these because of its reliability and accuracy, even in challenging environments.
The new procedure will allow Doosan Infracore to label and trace the path of all its components throughout their lifetimes. It should reduce the risk of faults in the machinery that could be dangerous for construction workers. The process will also guarantee that replacement parts are chosen correctly, because all the necessary information will be contained on the parts.
It will also automate machine production, by providing a way for robots to identify the different parts and place them during assembly.
