Abstract
This invention is directed to an automatic inspection system of welding spots in the car body and a control method thereof, the automatic inspection system comprising a controller and a robot arm, a probe device, and a visual system, wherein the robotic arm holds a camera and the probe device, the probe device targets at car body welding spot and form the first included angle with the camera. Many lighting sources are distributed around the camera, which form the second included angle with the camera. The camera is connected with Image Collecting and Processing Device to obtain position data of welding spot in the car body, the controller is connected with Image Collecting and Processing Device by network, and foresaid controller rectifies position of the probe on the robotic arm according to the position of welding spot in the car body.
