Microvision servo-system of platinum aurum fiber drawing bushing nozzle arc welding robot and the method thereof

Microscopic visual servoing platinum wire drawing method of arc welding robot drain nozzle plate board, which belongs to the platinum wire drawing a glass fiber production bushing BACKGROUND processing. Microscopic visual servo system by the vision lighting, microscopy, imaging devices, video capture module and the video processing computer. Microscopic visual servo method to achieve precise positioning of the center of the discharge spout, so that the robot can automatically adapt to the welding process heat deformation of the nozzle plate, accurate seam tracking, comprising: a microscopic vision center of the discharge spout visual servo positioning method and rapid methods. Fast positioning the discharge spout center-implemented method discharge spout center coarse positioning, noise tolerance capability, the positioning process is simple and fast, does not involve the complicated operation, providing real-time feedback to slip into the center position of the motion control system to achieve microscopic visual servo fine positioning the discharge spout center .
