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.

content:

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. As shown below:

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. High-speed motion requires that the interval between the two images be as short as possible. Smoothing means that the start-stop is smooth and no jitter during the movement, and the phenomenon that the “smear” causes interference to the image and affects the detection effect is eliminated. The ADTECH R&D team developed the latest control card products according to the characteristics of AOI industry. In the high-speed operation of the motor and the smooth control of the start and stop of the motor, the performance is particularly outstanding! The control card provides a variety of acceleration and deceleration processing, including trapezoidal acceleration and deceleration, S-type acceleration and deceleration and E-type acceleration and deceleration, acceleration and deceleration mode can be used according to different application settings. As shown below:


ADTECH engineering application team is very familiar with the process requirements of AOI, and has accumulated rich experience in visual applications. It has successfully developed many application cases including visual inspection, visual positioning and visual rectification.

In the present CNC machine tools industry, robotic tool change has become mainstream. Compared with other tool change methods, the robot tool changer has the characteristics of faster speed, and higher accuracy, and smaller motion range of various mechanical components.However, in the robot tool change, there are also the following pain points:01.The action of tool magazine robotic arm is inaccurateEach start and stop of the tool change action made by the robotic arm sends a brake signal to the controller through the tool magazine itself. After receiving the brake signal, the controller immediately sends a broken robot to rotate the output. This part requires the controller to have a higher signal processing speed. If it is not reached, the robot will not be allowed to move.02.The memory e...
