Edge AI vision inspection has already solved the problem of judgment speed itself on battery-pack assembly lines. Combining gas imaging with edge computing, as in GM's disclosed leak-inspection system “BVSeal,” makes per-cell judgment within 3 seconds possible. However, depending on where the judgment result is stored — the edge device locally, a gateway, or the cloud — the completeness of Traceability data remains an entirely different problem. This article compares the data architecture of edge AI vision inspection from an interface-design perspective and presents, as a target scenario, a gateway-aggregation approach that secures Traceability completeness without takt-time loss. 1. Judgment Has Gotten Faster, But the Record Still Breaks To state…
