Outline
Since the line has to be stopped when replacing the electrode tip, the Overall Equipment Effectiveness (OEE) improvement of the automatic production line and manufacturing cost of per vehicle will be affected directly. To address this issue, this paper analyzed the electrode tip replacement time and frequency, used the linear programming model method to build a data replacement analysis model, summarized the risk level of replacement in different scenarios according to practical experience. At the same time, the standardized method of “fixed person, fixed time, fixed station” was implemented, and the final solution was determined after repeated iterative adjustment. After the grouping electrode tip replacement according to this strategy, the replacement frequency and time of electrode tip in the production line area has been reduced, and the overall OEE index has been significantly improved. At the same time, the cost of unit vehicle auxiliary materials was also optimized.
