The control card in the automatic optical inspection industry

Key words:

AOI, motion control, machine vision, automatic optical inspection, motion control card

Overview:

AOI is an automatic control system that combines motion control and machine vision. Machine vision completes the photographing and contrast detection of the workpiece. The motion control module controls the motion of the workpiece or controls the camera movement to assist detection. In this industry, the motion control method is point control and has two requirements of high speed and smoothness.

Automated Optical Inspection (AOI) is an effective method for industrial automation. This technology combines motion control with machine vision and is widely used in LCD/TFT and PCB industries. When automatically detecting, the machine automatically scans the workpiece through the camera, collects the image, compares the image with the qualified image in the database, and after image processing, checks the defect on the processed workpiece, and displays the defect through the display or automatic mark.
