Develpoment Of Efficiency And Analysis The Prevention Of Occupational Disease On Fuel Injector Assembly Line

Although through several years improvement,current manufacturing line of fuel injector is very efficient,the time difference of different operate station,which makes it hard to improve the whole efficiency potential of the whole manufacturing line,and wastes the ability of machine and human resource.So this article tries to search for a way of improving the efficiency of fuel injector assembly line.Firstly,this paper introduced the development situation of fuel injector which is relative to my project was analyzed.Secondly,interrelated theories were studied,such as assembly line theory,predetermined time standards and MTM.Especially for Methods-Time-Measurement.Then the current situation of fuel injector assembly line of BS company were investigated and researched by making on-the-spot observations,communicating with operating workers in depth and recording some operating videos.Some methods like 5W1 H and ECRS were used to improve the whole assembly line.What’s more important,MTM-1 were used to analyze and improve the bottlenecks of this assembly line,and the bottlenecks was developed according to the time table of bottlenecks,and the result is great.On the basis of MTM-1 analysis,the risk of Musculoskeletal Disorders of operating workers were estimated with OCRA,and harmfulness of this assembly works were distinguished,and some methods were proposed to overcome the risks and harmfulness.The methods put forward in the paper were applied in fuel injector assembly line of BS company.It is suggested that working time was reduced by 10.3%,and the assembly line was more balanced.The risks of Musculoskeletal Disorders was reduced and workers are more positive.
