Abstract
With the rapid development of robot technology, industrial robot applications are constantly expanding, welding robot technology has great development, to enhance the quality and efficiency of welding, we developed a car specifically on the pedals for spot welding Coordinate welding robot. This paper describes the development of a robot, the application status at home and abroad, and its tremendous superiority, the specific design requirements of the robot, the robot's overall programme design and structure of specific components of the drive design and calculation, while the machine The control of a part of the development, including the exchange of permanent magnet servo motor of the closed-loop system, it has rotary encoder feedback components for the election Mitsubishi servo drives a Mitsubishi driven by FN Series PLC for controller, another increase in positioning module , The robot to enter the program and a PC display. Robot is also a position control system, the location of robot movement control. Keywords welding robot structural design of closed-loop control
