Abstract: The smart transformation and digital upgrading are represented by a new frontier for the transformation and upgrading of industrial chains,as well as being a new dynamic for the development of new high-quality productive forces. A parallel development model for labeling equipment based on digital twin technology was proposed to solve the problems of high development cost,poor interoperability of multi-source data,low degree of digital and intelligent integration,and imprecise of manual labeling. A parallel development architecture was designed and a high-fidelity digital twin model and an OPC UA data interaction framework were established,through the integration of collaborative robots,Vision Master (VM) vision system,Mitsubishi Programmable Logic Controller (PLC) control system,and Visual Components (VC) digital twin technology. The virtual and real mapping of physical layer devices,acquisition layer data,and twin layer signals were configured by VC. The layout,process,and control program of the equipment were virtually debugged. The goals of lean development mode,precise labeling,synchronized virtual and real operation and maintenance,and digital and intelligent transformation were achieved. The experimental results show that the average one-time labeling qualification rate of flat products is improved by 4.3 % using the automatic labeling equipment. The maximum update time of the production line twin data is 131.8 ms. The parallel production line development model reduces costs by 18 %,shortens the development cycle by 26 %,and the timely repair rate of line faults is improved by 53 %.
