(Faw-volkswagen Automotive Co., Ltd., Tianjin Branch, Tianjin 300000) Abstract:in order to improve the production efficiency of automotive welding workshop with high flexibility and high automation rate, the takt time of production line needs to be optimized. This paper analyzes the method of identifying the takt time bottleneck station through the takt time balance graph, and summarizes in detail the takt time optimization methods: how to improve the running speed by optimizing the robot trajectory and equipment parameters; how to reduce action waste by optimizing equipment action sequence and equipment improvement; how to improve the processing speed by optimizing the process. The implementation of the above takt time optimization methods can effectively improve the production efficiency of the welding line and realize cost reduction and efficiency improvement. Key words: Automobile, Welding line, Takt time optimization method, Production efficiency
