Real-time process optimization (closed-loop feedback)
Multi-parameter quality gates (weight, dimensions, labels, defects)
3D Profilometry:
Laser triangulation (10μm Z-axis resolution)
Volume calculation for density verification
Surface Defect Detection:
Scratch/contamination identification (0.05mm² sensitivity)
Spectral analysis for material verification
Label Inspection:
OCR/OCV at 300dpi resolution
Barcode/QR code validation (ISO/IEC 15415 compliant)
Feasibility Study (2-4 weeks)
Product characteristic analysis
Lighting/optics selection
System Configuration (3-6 weeks)
AI model training
Rejection logic programming
Validation (4-8 weeks)
IQ/OQ/PQ execution
