After film AOI
Features
· Precise numerically controlled integral surface RGB shadowless light source, fully imported industrial CCD and lens with tens of millions of pixels
· Highly integrated equipment structure, easy installation, stable system, simple operation & maintenance
· Online detection, seamless connection with production line MES
· Using the high chromaticity restoration algorithm, it can truly restore the color of the cell, and accurately distinguish the color difference between different cells or the color difference within the same cell, so as to perform high-precision sorting
