Automotive Weld Nut Inspection

Improperly placed and welded accessories can lead to costly downtime or recalls in the automotive industry. To cut back on errors, equipment is needed to verify that a robot has correctly placed multiple weld nuts.


After a robot inserts multiple weld nuts in an automotive component, a worker places the part onto an inspection station equipped with two PresencePLUS P4 GEO vision sensors. Improperly inserted weld nuts could be missing, upside down, or tipped to one side. The PresencePLUS P4 GEO inspects to see that the weld nuts are present, correctly oriented and not leaning. The PresencePLUS P4 GEO compensates for part-to-part movement and can inspect from a long distance.
