Abstract：To improve the intelligence level of the palletizing workstation,based on the five-dimensional model theory of digital twins,SolidWorks 3D modeling software is used to create a three-dimensional model of the physical palletizing workstation.The 3D model is transformed into a virtual palletizing workstation using the simulation software Simreal.The physical properties and initial parameters of the six-axis industrial robotic arm,pneumatic suction cup,sensors,and other mechanisms in the virtual palletizing workstation are set.A programmable logic controller is used to design and implement the process flow of the palletizing workstation.Data interaction and real-time communication between the physical and virtual palletizing workstations are achieved through communication protocols such as Modbus and Siemens S7,constructing a digital twin system for the palletizing workstation.Experimental tests are conducted to validate the functionality of the palletizing digital twin system,with online visual monitoring of the system's operational status and verification of data transmission accuracy and real-time performance.Research shows that the constructed palletizing digital twin system can synchronously map the actions of the physical palletizing workstation,collect data such as productivity during the palletizing process,improve the accuracy of material placement to over 99％,and prevent misalignment occurrences.
