Controlling traceability of torque converters and engine valves is necessary to verify the correct part type is matched with the engine. Data Matrix codes are laser marked directly on the surface of the converters and valves to control traceability. Code contrast is typically poor and parts are often coated in oil. Because each part has specific characteristics that affect engine performance, if the incorrect part has been assembled into the engine it will negatively impact its performance and potentially result in a recall.
Cognex DataMan® image-based barcode readers can easily read these challenging codes thanks to an advanced image formation system. The data from the reader is used to verify that the correct components are assembled into the engine which minimizes the risk of recalls.
