Research On Material Sorting System And Realization Of Digital Twin

In the production process,material sorting is a very important link,which affects the rhythm of the production line and the subsequent process quality.At present,many domestic enterprises in the production process of material sorting mainly rely on manual completion,low efficiency,high labor intensity.With the continuous development of intelligent technology,industrial robots,machine vision and other intelligent manufacturing technologies are applied to the material sorting system,which greatly improves the speed and quality of material sorting and improves the production efficiency of enterprises.The integration of digital twinning technology in the material sorting process can realize the optimization of the material sorting process and the monitoring of the whole life cycle,and further enhance the intelligence of the material sorting system.The main research work is as follows:(1)Overall design of material sorting system.Firstly,the sorting object of the sorting system is determined,the process flow,module composition and function of the sorting system are studied,and the overall design of the material sorting system based on industrial robot and industrial vision is completed.The three-dimensional digital model of the material sorting system was established based on Solid Works software,and the finite element analysis of the key parts of the mechanism was carried out by using ABAQUS software.According to the sorting process,the industrial robot is selected,and the mechanical structure design of the walking shaft module,the well type feeding module,the belt conveying module,the servo positioner module and the quick tool changing module are completed.(2)Research on material sorting control system based on industrial vision.The PLC,man-machine interaction interface and air pressure system of the material sorting control system are designed.Building materials based on industrial visual identification system,using hoff circle detection and Canny edge detection operator and template matching to realize positioning,and then complete the precise identification of the material,and the identification results to general control systems,industrial robot according to the result of the total control system implementation of fetching,complete material intelligent sorting process.(3)Based on IRobot SIM digital twin software,the digital twin model of material sorting system is studied.Based on the API function of hslcommunication component of Modbus TCP communication protocol,the communication between IRobot SIM digital twin software and the physical system is realized.The cooperative movement of the material sorting system and the digital twin system is realized.(4)The experimental system is designed,and the material identification,grasping,digital twinning and other experiments are carried out on the experimental system.Based on different template matching method,the successful positioning and grasping of materials are realized.The communication between the digital twin software and the hardware entity is successfully completed,and the virtual and real synchronization test is carried out.The experiment proves that the material sorting system runs safely and reliably,which improves the efficiency and reduces the labor intensity.
