ABSTRACT:
The present invention provides a system and method of detecting the correct and complete loading of parts in one or more assembly fixtures. A missing or incorrectly loaded part results in an airflow from a respective part cavity in an assembly fixture and a switch assembly, which can be located distal from the assembly fixtures, detects the airflow and provides a signal indicating that the fixture is not correctly loaded. Conversely, if each and every part is correctly loaded into the assembly fixtures, no airflow occurs and the switch assembly outputs a signal indicating that the assembly fixtures are correctly loaded and that subsequent manufacturing/assembly operations can be performed.
