    Quick Answer

    NeoBram deploys computer-vision quality inspection on manufacturing lines - real-time defect detection, surface inspection, assembly verification and dimensional gauging using YOLO and SAM2 models on edge GPUs, integrated with your MES so rejects are tracked and root-caused.

    Why This Matters

    Human Inspection Misses Defects. AI Vision Doesn't.

    Human visual inspectors typically achieve 80-90% defect catch rates and degrade across an 8-hour shift. Customer returns and warranty claims from missed defects routinely cost manufacturers 1-3% of revenue.

    Modern computer vision combines high-resolution machine-vision cameras, structured lighting and deep learning models that learn from a few hundred labelled images. Catch rates of 98-99.5% are now standard, with sub-100ms cycle times that match line speed.

    We deploy production CV systems on your line in 6-10 weeks - cameras, lighting, edge GPU, model training, MES integration and a labelling and retraining loop so the system improves as new defect modes appear. No cloud dependency for inference.

    How We Build It

    Defect & surface inspection

    Detect scratches, dents, cracks, contamination, missing features and surface anomalies at line speed across metals, plastics, electronics, glass and textiles.

    • 98-99.5% catch rate with <0.5% false-reject rate
    • Few-shot anomaly detection for rare defect classes
    • Multi-camera 360° inspection of complex parts
    • Sub-100ms cycle times to match line takt

    Assembly & presence verification

    Verify correct components, orientation, fastener presence, label placement and barcode/datamatrix readability before parts leave the cell.

    • Presence / absence / orientation verification
    • Fastener and connector seating checks
    • Label, batch code and datamatrix OCR
    • Colour and texture matching

    Dimensional gauging

    Sub-pixel dimensional measurement with calibrated telecentric optics - SPC-grade gauging without the cost of a dedicated CMM.

    • Sub-pixel edge detection with telecentric optics
    • Gauge R&R compliant for SPC
    • Statistical process control dashboards
    • Drift detection on critical dimensions

    MES integration & retraining loop

    PLC handshake for automatic reject, MES integration for traceability, and a labelling pipeline that retrains models monthly as new defect modes emerge.

    • OPC UA / Profinet PLC handshake for reject gates
    • Reject and root-cause tracking in MES / SAP QM
    • Operator review UI for borderline calls
    • Monthly model retraining on new labelled defects
