Presented by Jaeyoung Kim, Korea Institute of Machinery and Materials (KIMM)

The Roll-to-Roll (R2R) continuous manufacturing system is a system that utilizes multiple rollers to transfer and process a flexible web based on speed and tension control. Recently, the Roll-to-Roll system has been employed in the continuous manufacturing process of energy components such as ICT devices, lithium-ion battery cells, and solid-state battery cells. As the market for energy component manufacturing continues to grow, there is an increasing demand for fundamental technologies in high-precision Roll-to-Roll manufacturing systems. To achieve this, it is necessary to establish the foundation for Roll-to-Roll digital twin technology, which enables the simulation of the actual system by reflecting data within a digital platform that can visualize aspects that are difficult to observe in reality. Furthermore, real-time monitoring of operational changes should be conducted through system synchronization to enhance the efficiency of equipment operation and management. This paper aims to introduce the direction and fundamental technologies for the development of key technologies in the Roll-to-Roll digital twin system. This includes the development of core components/modules for Roll-to-Roll systems, the creation of control simulation models, the construction of an integrated AI optimization system utilizing Artificial Intelligence (AI), and the implementation of a digital platform for Roll-to-Roll systems to enable the implementation of digital twin system.
