Description

Simulation Method and Device of Lamination and Stack Apparatus for Secondary Battery Production The present invention relates to a method and apparatus for simulating a lamination and stack (L&S) device for secondary battery production, and specifically, to a method and apparatus for simulating a lamination and stack (L&S) device for training secondary battery production workers. Due to the recent growth of the electric vehicle market, the demand for the development and production of secondary batteries is increasing rapidly. In response to this growing demand, the number of production plants for secondary batteries is also rising. However, there is a significant shortage of skilled workers to operate these secondary battery production facilities. Meanwhile, training and education for new workers were previously conducted by having them learn by observing experienced workers; however, due to the busy secondary battery production schedule, it was difficult to provide training and education for new workers over an extended period. In addition, there is a problem in securing a sufficient number of skilled workers due to factors such as frequent turnover. Furthermore, even if workers are trained on general factory operation methods, it is not easy to ensure that they can immediately respond to various types of defect situations that may occur during factory operation.
