Automated Visual Inspection FAQs
How do you handle shiny or highly reflective metal surfaces during optical inspection?
We utilize specialized lighting geometries such as cross-polarized diffuse dome lighting, coaxial illumination, and custom polarizing filters. These configurations suppress specular glare and hot-spots, allowing the camera to capture true surface topography, micro-cracks, and scratches without optical reflection distortion.
How is the camera triggered precisely on a high-speed moving conveyor belt?
We interface a high-speed photoelectric sensor or an incremental rotary shaft encoder directly into the vision hardware trigger port. This guarantees image acquisition at the exact microsecond a part reaches the optical center of view, remaining immune to conveyor speed fluctuations.
When should deep learning (AI) vision be used instead of traditional rule-based algorithms?
Traditional rule-based algorithms (thresholding, edge detection, blob analysis) excel at precise dimensional gauging and mathematical pattern matching. Deep learning (AI) models are ideal for complex, organic, or unpredictable defects like surface scratches, fabric tears, weave flaws, or natural food product discoloration where rigid mathematical boundaries fail.
What reject mechanisms can be integrated with the vision inspection system?
We integrate multiple high-speed reject mechanisms based on line speed and product mass, including pneumatic air-jet nozzles for lightweight components, fast-acting linear pusher rams, diverter flappers, and high-speed multi-axis pick-and-place robots.
