Outline
In order to solve the problem of insufficient production capacity in the welding work shop, through the analysis and research on the production line production capacity bottleneck area, 2 process optimization methods, i.e. process rebalancing and process sequence optimization, were applied to reduce the station cycle time according to the characteristics of different stations. In the implementation process, the image motion analysis method was utilized for motion decomposition of each station, to reveal the small steps of every part. At the same time, ECRS principle was used to optimize the optimization points. Finally, the cycle time optimization was successfully implemented for the 2 spot welding stations. The cycle time reduction directly improves the production capacity of the production line. There was no parameter adjustment for the optimization of spot welding process, which provided another approach to reduce the cycle time of similar station.
