Monorail articulated robot driven by servo motor
Abstract: With the development of productive forces continuously, the modernization of production increasingly, robots are increasingly appeared in the modern the important production areas, and the development trend of continuously. Especially in the artificial production can't meet the production quality and efficiency of the industry, is widely applied to. Among them, the application of welding robot, makes great changes have taken place in welding field. Because of the complexity of the welding process, welding quality of high demand, the manual is hard to accomplish these tasks efficiently, and welding process is very boring, work environment also has certain risk. Therefore, adopting the welding robot to replace most of the welding task has the important meaning.
This paper mainly introduces a kind of single track multi-joint robot servo motor driver, introduces in detail its mechanical structure and drive mode and control mode and the transmission mechanism. The robot with five degrees of freedom, each joint is of rotation connection, and driven by servo motor, control flexibility, large work space, can achieve the task. Mechanical arm wrist wrist structure adopts a differentia speed, can realize freedom pitch and rotate, for welding procedures, very flexible and convenient.
Keywords: Servo motor, single track, multiple joints, welding
