Automatic Solar Module EL and AOI Appearance Tester
Applications:
The EL Tester consists of four near-infrared cameras (high quality 0.4mm/pixel), while the AOI Appearance Tester system comprises another four visible light cameras (high quality 0.09mm/pixel). These cameras respectively capture EL infrared images and visible light images, ensuring comprehensive defect detection across both imaging spectra in the solar panel production line.
By utilizing multi-station image acquisition and multi-camera image stitching, the solar cell testing machine generates complete EL Testing and AOI visual images of the solar panel production line. This method guarantees high-resolution imaging, enabling precise defect detection with a small window feature for detailed section analysis. It is essential for accurately identifying both EL Inspection defects, such as hidden cracks and dark spots, and AOI Inspection defects, such as foreign matter and color variations, in solar panel production lines.
The EL Testing and AOI Appearance Testing of PV panels can function either as independent detection systems or be integrated into a single combined detection system. This flexibility of our EL and AOI Appearance Tester allows seamless integration into automated solar panel production lines, ensuring high detection accuracy and efficiency.
