■Invar Inspectors Video
– (Fe+ NI) Automatic inspection after scanning with Film Line Scan Camera (AOI)
– Map display by defect item (quickly check which areas are defective)
– Verifying defective location X.Y coordinates
– Go to the XY coordinates obtained with the AOI camera and check the presence or absence of defects at high magnification
– AF of pattern (CD) size to measure upper and lower high magnification CD
Measurement
Display-Film Inspection Machine
This facility is a 2D vision inspection device that detects poor appearance of mobile liquid crystal films.
A multi-image combination of high-brightness LED autonomous lighting (OEM special optical system) takes one sample eight times,
It generates reflectance, roughness, slope data, etc. using its own image processing algorithm using the photographed image..
A.I Vision System (including Rule Vision) is a system that inspects and classifies defects in appearance through algorithms.
