Design of Loading and Unloading Machine Hand for Automatic Production Line of Vehicle based on Servo Drive

摘要

Robot was developed to give a new mean of mechanization and automation of the production process. The design of the robot is used in the automotive automatic production line for loading and unloading of the workpieces. It is from the base, the mechanical arm parts, the wrist rotation parts, and the Interchangeable holder. It possesses a balance of performance properties including: It can capture the object changing the orietation, it can determine the weight of the object, and automatically avoid obstacles, while grasping an empty or insufficient grip strength and other properties can be detected. The robot system mainly consists of three parts: mechanical transmission devices, electrical drives, computer-controlled devices. Mechanical robot body structure using operational body structure, similar to the human arm and wrist, can be coupled with a variety of crawling and a variety of job actions and grasping after the end effector. Technical parameters given by the visible need to use cylindrical coordinates robot. Hand body movement depends on the mechanical structure of the servo drive, which the design is driven by DC servo motor.
