The Power Window Symbol Vision & Illumination Inspection Machine is a high-precision automated vision inspection system designed to ensure accurate symbol marking and illumination quality of automotive power window switches. The system operates inside a controlled dark-room enclosure, eliminating external light interference, and utilizes servo-based motion control for repeatable and stable part positioning. Integrated with AVT and Basler industrial cameras, the system delivers ultra-high-resolution image analysis for flawless inspection of symbol engraving, laser marking, and LED illumination intensity.
