The gas generators used to inflate airbags are critical to automotive safety system performance. Proper function of the gas generator requires that all components be included and positioned correctly. It is difficult to meet rigorous specification standards because manual inspection does not provide the positional accuracy required.
Cognex vision systems enable manufacturers of safety-critical components and assemblies to automatically inspect for part presence and verify part location with high accuracy. Cognex vision tools locate the position of the airbag canister in the field of view and adapt to changes in lighting caused by the parts’ curved reflective surface to make a pass or fail decision based on standard specifications.
