摘要因客户要求逐渐提高,组件错位不良(不良率达0.7%)这个问题也浮出水面,本文主要以质量改进技术为工具,以PDCA循环为工作流程针对该问题进行推进改善。需先对主要测量工具进行MSA分析(测量系统分析),当测量系统达到稳定后,组织各部门成员进行头脑风暴,群策群力制作因果图,从人、机、料、法、环这五个方面进行原因分析,通过质量工具对9条末端原因进行逐一验证,最终判定员工质量意识不足和电池串片间距差异大为要因。通过对生产员工进行宣导,同时设备人员对串焊机台进行调试,再次收集数据,错位不良率为0.01%,错位问题得到有效控制。 Due to the request of customer increases gradually,problem of battery string dislocation appears, because of the failure rate of dislocation is high（0.70%）,this article mainly aims at the improvement on the dislocation problem.In this study,the main content is the application of quality improvement technology,according to the PDCA cycle steps to improve the quality of product.The research premise is analysis measurement systems.After the measurement system is stable,call each department personnel do brainstorming,draw on the wisdom of the masses,from man,machine,material,method,environment,measurement to do reason analysis,verify the nine reasons one by one,Finally,find the key reasons are insufficient quality conscious- ness of staff and large difference of the distance between piece and piece cells.Through promoting produ- ction staff,ancl debugging welding machine by equipment personnel,Analysis of variance was carried out on the spacing of found no significant difference,collect data again,failure rate of dislocation is 0.01%,dislocat- ion improved effectively.
