电源适配器生产现场改善与装配线平衡

Improvement of Process and Line Balance in a Power Adapter Assembly Line

以某企业电源适配器EA1xx型号产线为研究对象,通过模特法和秒表测时法测定流水线各工位的作业时间,找出了流水线上的瓶颈工位。运用"5W1H"的方法分析流水线在任务分配、定员、工序的安排和作业工具等方面存在的问题。根据ECRS的原则和流水线平整的方法,提出了相关作业内容的重新分配、工具设备的改进、工位作业时间和人员的调整及加强对产线的巡检力度等方法。新方法的实施使产线的产量提高23%,产线平衡率提高12.26%,年节省人工费用31 050元,每小时产量提高46台,生产现场的环境得到了较大改善。

An existing assembly line for a power adapter in a factory is studied.With MOD method and stopwatch measuring,the processing time needed for each activity is determined such that the bottle-neck is located.Then,by using 5W1H and ECRS,the assembly process is redesigned so that the line balance is significantly improved.By doing so,the productivity increases by 23%,the balance rate increases by 12.26%,labor cost reduces $31 050 per year,output increases 46 pieces per hour.
