Study On The Control System Of Welding Positioning Robot Based On Trio Motion Controller

In order to meet the accelerated rhythm of modern automobile production and the continuous improvement requirements of automobile welding process, It's fast and accurate to complete auto chassis positioning and change positioning place between different models in the same production line by using flexible,intelligent,high-precision three-axis welding positioning robot to replace the traditional fixed auto chassis positioning equipment in the auto chassis welding production line, which is meaningful to built automobile flexible production line and increase productivity.This paper has developed a three-axis welding positioning robot with Cartesian coordinate structure and built its motion control system, the specific work done in this paper including the following aspects:First, this paper simply introduced the history and the development trend of industrial robot, especially introducing the concept and developing condition of open architecture control system of robot, Then discussed the background and the significance of using welding positioning robot and made a decision to build an open architecture motion control system based on PC+motion controller, and the control object is the three-axis welding positioning robot.Secondly, analyzed the structure and main functional requirements of the welding positioning robot in detail, and proposed the whole program of building a welding positioning robot system—construct an open-architecture control system based on IPC and Trio MC206 motion controller.Again, designed and realized the hardware of welding positioning robot open-architecture control system, including the structural design of the robot body, selection of PC, the research of Trio MC206 motion controller, the determination of the robot servo system, and the whole electrical connection of the system.Finally, developed the software of the welding positioning robot control system by using C# programming language based on Windows XP operation system and Visual Studio 2008 software design platform, designed the structure and man-machine interface of the software, discussed the way to realize each function module in detail. In the final of this paper an experiment has been made to illustrate the functions of the control system developed in this paper can meet the positioning requirement of auto chassis.
