Accurately and quickly removing defective products from the production line directly affects the inspection accuracy. High-precision gripping robotic arms are widely used in this process. Traditional robotic arm gripping uses a fixed pattern; when an external trigger signal is given, the robotic arm executes the gripping action. This method may lead to inaccurate gripping when gripping items on high-speed production lines. This paper proposes a high-precision robotic arm servo system based on machine vision, improving upon the traditional robotic arm motion control mode, specifically for the characteristics of bottling production lines in the beverage and pharmaceutical industries. This article uses a high-speed beer production line as an example to describe in detail the motion control system process. 2. Vision Servo Control System Structure After the detection system determines the secondary bottle to be separated, the robotic arm, through the cooperation of the vision system and the control system, quickly positions itself directly above the secondary bottle. The positioning sensor is a camera, mainly responsible for positioning the robotic arm before grasping, ensuring that the robotic arm stays directly above the object to be grasped. The camera transmits the image information of the object to be grasped to the industrial control computer. The industrial control computer can output control signals to the active robotic arm based on the positional calibration information of the object to be grasped to complete the precise positioning of the robotic arm and move according to the speed of the conveyor belt.
