Abstract: In response to the problem of production capacity waste caused by unbalanced process rhythms on automotive assembly lines, this paper, in combination with the lean production concept, explores the application path of line balancing technology in enhancing the production capacity of multi-model mixed lines, aiming to improve the enterprise's capacity switching ability between peak and off-peak seasons and market response efficiency. By analyzing the production and assembly process of new energy vehicle models, this article adopts a modular approach to decompose the operation units, quantifies the standard operation time of each process, uses the line balancing method to optimize the capacity bottleneck of the line body, and implements a dynamic adjustment strategy for line division. This method effectively reduces process waste, improves the overall balance rate and final capacity output of the assembly line body, providing a feasible technical support and solution for the flexible production of assembly lines.
