With the development of the social manufacture, the intense repetition has been appeared inevitably in the modern industry; accordingly the assembly line comes into being. It has been proved that the operative mold of assembly line is an effective way which is suitable for massive production and management, and it has been attracted more and more social concern. The imbalance of the industrial assembly line not only reflects its efficiency but also influences the quality of products. This paper focuses on the general assembly line of solar energy rime of ShaoXing JingGong of Electromechaincal Research institute Co. Ltd, based on summarizing and analysizing some references, through researching the present assembly line autoptical and measuring the relevant data, analysizing its balance state by using the diagram of speed, according ECRS and active economic rules, improving time , including splitting and regrouping its intrinsic working procedure, so as to eliminate the bottle-neck phenomenon. After implementing the new project, the balance rate of assembly line will increase to 31.48% from intrinsic 49.74%.
