Final Assembly Inspection Booth
A final inspection booth has one job: to make the defect visible to the operator rather than to the customer. What determines this is not the equipment but the geometry of the light.
How the process works
A surface defect becomes visible when light strikes the surface at a shallow angle. Light arriving perpendicular hides the defect. Luminaires in inspection booths are therefore arranged around the part at specific angles, usually forming a light tunnel.
If colour is to be assessed, the colour temperature and colour rendering index of the light must comply with the standard. In a booth where two luminaires of different colour temperature mix, a colour decision is not reliable.
A defect marking and recording station makes it possible to track what was found and where it went. Inspection without records produces no data for root cause analysis.
