IV.
Inspection Capabilities
Defect Inspection: Surface scratches, missing components, misalignment; Precision: Sub-micron level (requires AI layer; source: Averroes); Code Reading: Barcode/OCR; 3D: Height/flatness inspection; AI Deep Learning: Defect library + model training (source: Cognex)—Capabilities: 2D + 3D + AI (selected based on defect type).
V.
Selection Criteria
1. Defect type (scratches/assembly/dimensions); 2. Speed (cycle time/fps); 3. Camera count (single vs. multi-camera); 4. AI requirements (complex defects); 5. Lighting (industry-specific lighting; source: LUSTER)—Selection: Defect type + cycle time + AI (submit samples for testing first).
VI. Supplier Evaluation
1.
Industry case studies (similar product lines); 2. Defect template library (LUSTER: 2,800+ templates; source: industry reports); 3. Algorithm patents; 4. Service (debugging + training); 5. Scalability (continuous AI training)—Evaluation: Case studies + template library + algorithms (submit samples to test for missed detection rates).
7. Procurement Recommendations
Choose Cognex for complex defects (leveraging deep learning AI); Keyence for rapid deployment; LUSTER LightTech for semiconductor packaging; and OPT for 3D inspection.
Finally, submit samples for testing first (validating against missed detection and false alarm rates)—for vision inspection lines, consider international brands like Cognex and Keyence, or domestic brands like LUSTER LightTech and OPT (requiring sample testing and acceptance based on missed detection rates).
