The paper describes the welding auxiliary equipment of the general concept of function and application of analysis of core intelligent variable - bit system , and part of the mechanical structure of the positioner , summed up the general design method of welding positioner . To the rotary tilting positioner , for example , pushed to the universal algorithm of inverse kinematics and unique solution . Through the analysis of the mathematical modeling method , from mechanical parts to enhance the the displacement position accuracy and repeatability , and to improve the mechanical properties of the entire intelligent variable - bit system . Displacement system based on improved intelligent variable - bit system to enhance the electrical hardware foundation , PLC plus inverter and encoder combination to achieve the speed and position of the closed-loop control , to improve the accuracy of the system control , IPC PLC the master-slave control mode to develop intelligent variable -bit systems significantly enhance the technical performance of the positioner . Control method using fuzzy control technology plus classic PID control technology to enhance the dynamic characteristics of the variable - bit system , and its control accuracy and response speed to be increased dramatically . Software design , the use of object-oriented programming methods and multi-threading technology , the development of control system software for welding positioner system . The control system software has very good scalability , and provides a good foundation for the the welding positioner system extensions and smart upgrade . Bring obvious benefits to reduce costs and product development cycle . Specific PLC and IPC serial communication protocol and communication subroutine , a more detailed discussion , and gives a flowchart . In the research and development of the turret shell intelligent welding system , the full application of the above techniques , not only to improve the welding speed , and improve the quality of welding , to achieve the intended purpose .
