Automated Extrusion Inspection System

The Extrusion Visual Inspection System (EVIS) automates the inspection and defect analysis of long rectangular extrusions, either as 6 to 8 foot long pieces (offline mode) or as one continuous extrusion (inline mode). The EVIS quantifies the magnitude of extrusion flaws in each part that is inspected. The system classifies each part as good, minor defect or major defect and in offline mode automatically sorts output pieces based on the classification. Part width, height and length are also measured for compliance. In inline mode the extrusion is continuously monitored for manufacturing flaws. Inline mode provides a mechanism for cutting parts to a specified length and detected defects are automatically cut out to short lengths for recycling in the extrusion process.
