Quality Control

High-Speed OCR & Barcode Verification Problem Statement: In the mass production of product labels, ensuring that the printed human-readable text (OCR) matches the machine-readable barcode is critical. Manual inspection on high-speed reel-to-reel machines is impossible, leading to risks of mixed data, missing prints, or unreadable codes reaching the end customer. The Challenge: The client needed a system capable of inspecting every single label on a moving roll. The challenge involved not just reading the data, but performing a Dual Validation Cross-check—verifying that the alphanumeric string (OCR) perfectly matches the decoded Barcode data in real-time, while also controlling the machine’s motor to stop immediately upon detecting a defect. ...

Adaptive Visual Inspection for Stamped Parts Problem Statement: In automotive part manufacturing, “Stamped Characters” (serial numbers/codes) are critical for traceability. However, the physical stamping process is inconsistent. Factors like die wear, hydraulic pressure changes, or slight positioning shifts cause the characters to look different over time. The Challenge: A traditional Vision System uses a static “Master Image.” When the production line’s stamping tool degrades slightly, the characters no longer match the static Master perfectly. This leads to a high rate of False Rejects (Good parts being rejected), causing frequent machine downtime and requiring constant code adjustments by engineers. ...
