Our customer manufactures sealing sheets as continuous material in various product variants, which were previously inspected manually by employees during the ongoing process. Although the inspectors worked conscientiously, subjectivity and fatigue led to fluctuating results: OK goods were sometimes sorted out as NOK, while NOK goods passed through unnoticed. The consequences were increased scrap and a risk of customer complaints. The dark, textured, and partly reflective surface of the sheets, as well as the high product variability, made the use of classic, rule-based inspection systems unreliable. Maddox AI has developed an inspection device that is integrated directly into the existing production line and captures 100% of the moving sheet from above. A rotary encoder triggers the cameras with precise timing, the captured images are processed locally on the edge device, and the inspection result (OK/NOK) is immediately transferred to the existing PLC. Detected defects include tears, holes, wrinkles, melted spots, bubbles, foreign objects, smears, and missing material – across multiple product variants. Changeover between variants is automatic: the operator simply selects the desired article number on the touchscreen.
