Research Of L Company NB Adapter Productivity Improvement

This paper introduces the development of power adapter at home and abroad and the status of production of L-Company,using the eight waste to find the main problems in the company,combined with the analysis methods of industrial engineering,to reduce cost and lifting efficiency and improve the product design,product process and production efficiency.In the product design surface mainly includes the raising the insertion rate,free-trimming and simplify the assembly three aspects.Raising the insertion rate by new equipment or new skill of auto insertion field,weed out the old equipment,improve the ability of the AI and RI machine,and also to reduce the hand insertion component to save the manual cost.In the trimming free process,grasp design and quality from the source to achieve the cancellation effect.When simplifies the assembly in the assembly segment,cancel the T-pin design,directly the shielding is made into the material,the wire is simplified into connection mode,the upper shielding is designed,the upper shielding sheath is changed to four-pin clip,the socket is to follow a simplified process to ensure the production quality.Process suface includes three aspects of production action waste,production line balance,line bottleneck station action research and time analysis.Establish reasonable production rhythm,standardize the number of production units,make production stable and orderly;Eliminate waste of action,reduce waste of time,improve capacity,reduce manpower;Improve the line balance,rearrange the operation,balance station,improve every hour capacity;Improve the stop line time,reduce the stop line time due to abnormal,make the fixture,material and otherfactors with more buffers to achieve the purpose of rapid processing.And to standardize all improvements,write to the working instruction executive document,will improve the effect of fixed continuation,long term effective.Finally,the production of a flow is from the push production to the pull production.The production efficiency surface contains the source of the automation project,the construction of automation team,the feasibility evaluation of automation program,benefit feasibility evaluation,automation schedule control and automation standardization.From the waste of production status and human workmanship,the automation team of high quality ability is established to save manpower,improve production efficiency,develop automation scheme,evaluate the feasibility and benefit of action man-hours,and control and standardize the progress of automation.From discovery problem to analysis problem to solving problems,step by step in-depth evaluation,finally to the standardization of automation and the compilation of the DFA project.
