【摘要】 文章基于后桥装配线平衡墙目视板,对各工位实际作业状态中的增值时间、非增值时间、等待时间和步行时间进行目视化分析,然后对后桥装配线瓶颈工位进行局部优化,消除了作业等待的闲置浪费现象,使生产节拍得到一定程度的降低。最后对平衡前后的装配线指标进行对比分析,实际生产节拍由60.0 s降低至48.8 s;装配线的平衡率由平衡前的69.5%提升至81.9%;平滑系数由19.5降低至10.4,较平衡前降低了9.1,优化效果比较显著,为进一步开展精益生产打下良好基础。更多还原

【Abstract】 Based on the visual board of the line balance wall of the rear axle assembly line, the value-added time, non value-added time, waiting time and walking time in the actual operation state of each station are visually analyzed, and then the bottleneck station of the rear axle assembly line is locally optimized to eliminate the idle waste of operation waiting and reduce the production beat to a certain extent. Finally, the assembly line indexes before and after balance are compared and analyzed. The results show that the actual production beat is reduced from 60.0 s to 48.8 s, the balance rate of the assembly line is increased from 69.5% to 81.9%, and the smoothing coefficient is reduced from 19.5 to 10.4, 9.1 lower than that before balance. The significant optimization effect lays a good foundation for further lean production.更多还原
