Design And Realization Of A Control System In Robot Stamping Production Line

With the rapid development of robot technology,the automated production line adopting robots as the carriers is the future development trend of manufacturing.Based on the frontier simulation technology to complete the entire production line planning,expected effect analysis,interference detection and other work in advance in the virtual environment,the reliability of the production line design can be effectively improved.while basing on field bus technology to achieve stamping production line automation to achieve high-speed,flexible decentralized control is a hot topic in current industrial control field.Therefore,using the simulation theory data combined with the actual field bus technology is the development trend of industrial automation and a practical and feasible production line design scheme as well.This thesis takes the stamping production line of the engine hood as the research object,utilizes SolidWorks software to achieve precise three-dimensional modeling of the equipment involved in the automatic production line,uses FANUC ROBOGUIDE software to drive the press moving die and perform whole design and verification on the layout of the stamping production line;Then,The interference detection technology,the optimal initial position selection method,the singular point avoidance method and the optimal path setting calculation method in the simulation environment are used to finish the trajectory planning and offline programming of the robot in the stamping production line and the robot’s path is optimized further to increase the production rhythm from the original 15.42 s / piece to 11.61 s / piece;At last,based on PROFIBUS-DP field bus technology and combining with simulation theory data,the control system of the whole production line is designed to realize the coordination of multi robot and multi press,and to monitor the running state of the whole production line,and finally realize with the actual production rhythm of 11.43 s / piece.The results show that the motion simulation of engine hood stamping production line in this thesis can be applied in actual production line,which greatly reduce the time spent on actual on-site installation and debugging and related economic losses.In addition,the error between production rhythm in the simulation and the actual production rhythm is within a reasonable range,which verifies the reliability of the simulation.Therefore,the control system designed in this thesis has wide applicability and provides important reference value for the design of automatic stamping production line.
