This study designed a labeling machine for lithium-ion batteries used in cell phones taking lithium-ion batteries as the study subject. Based on function, behavior, and structure, the system functional decomposition strategy was used, the overall function was decomposed into sub-functions. The corresponding solutions to realize the function of each structure were established according to the working principle of each function. The overall structure meeting the system function was obtained, and the working principle and the structure organization of the key components were also expounded. The field verification showed the proposed technique can meet the production requirements.
