Power Window Vision Inspection Machine – Child Part Verification

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.

Key Technical Features

• Vision & Illumination Inspection Technology.
• Equipped with Basler & AVT smart industrial cameras for precision vision inspection..
• Capable of verifying symbol accuracy, alignment, and clarity under multiple lighting conditions..
• Illumination intensity measurement through multi-stage image acquisition for white, amber, and dual-color LEDs..
• Dark-room setup ensures stable and uniform lighting, eliminating ambient reflection or glare..
