OverviewThe document describes an automated system for inspecting the cleanliness of part surfaces, focusing on detecting fluorescent organic contamination using ultraviolet (UV) light. The system is designed for flexible adaptation to new measuring tasks and is suitable for three-dimensional surfaces.
Measuring PrincipleThe system uses a UV-light source to excite fluorescent organic contaminants on metal surfaces. The intensity of the fluorescence radiation, which increases with the thickness of the contamination layer, is measured to assess cleanliness.
Application Examples- Automated inspection of die-cast aluminum before bonding.
- Inspection of soldering pads on printed circuit boards.
- Monitoring of anti-corrosive layers.
- Inspection of large metal parts before coating and printing.
- Process analysis and optimization by determining contamination dispersion on surfaces.
- Measurement of three-dimensional surfaces with a 3-axis system.
System Features- High reproducibility due to precise positioning without interference from user and ambient light.
- Measurement at process speed with high resolution through fast traversing speed and scanning rate.
- Flexible measuring programs with predefined functions and configurable sequences.
- Easy teach-in directly at the part.
- Multipart-Scan for efficient measurement of several parts in one run.
