[Abstract]:This paper introduces the development of power adapters at home and abroad and the analysis of the present situation of productivity in L Company, uses the eight waste in lean production theory to find out the main problems existing in the company, and combines the analysis methods commonly used in industrial engineering. Focusing on reducing cost and increasing efficiency, research and improvement is carried out around three aspects: product design, product process and production efficiency. Three aspects: no shearing foot, no repair and welding, and simple assembly. To improve the implant rate, to update the old equipment by introducing advanced technology, to improve the capability of the vertical plug-in, and to include the special-shaped plug-in machine in the field. Reduce the manual plug in order to save the labor cost of the plug-in operator, improve the overall level of the implant. When canceling the repair welding process of the shears, through the nature of the electronic properties of the product structure, trace back to the source of the shearing foot and repair welding problems, The design and quality should be emphasized from the source to achieve the cancellation effect. When the assembly section is simplified and assembled, T-Pinting is cancelled in combination with the front station, and the two ends of the aluminum sleeve are made into solderable materials directly, and the wire rod is simplified into the connection mode, and the integrated design of the lower aluminum sleeve and the insulating box is made. The aluminum sleeve is changed to four claw buckles, and the socket adds the function of preventing stay in order to follow the simplified process flow and ensure the production quality. The process surface includes the waste of production action, the balance of production line, Production line bottleneck position action research and time analysis three aspects: make reasonable production rhythm, standardize the number of production units, make production stable and orderly, eliminate wasted action, reduce waste time, improve production capacity, reduce manpower; Improve line balance, rearrange operation action, balance work station, increase production capacity per hour, improve line stoppage time, reduce stoppage time due to abnormal occurrence, back up influencing factors such as fixtures, materials, etc. To achieve the purpose of rapid processing. And all improvements standardized, written in the job instruction execution document, will improve the effect of a fixed continuation, Long effective. Finally realize a flow of production from push production success to pull production. Production efficiency bread contains looking for the source of automation topics, automation team building, feasibility evaluation of automation scheme, benefit feasibility evaluation, Automation schedule Control and Automation Standardization. The source of automation project is waste of production status quo and simplification of manual work. After discovering the project, set up a high quality and ability automation team to save labor. The theme of improving production efficiency, developing automation programs, evaluating feasibility and effectiveness of action hours of automation programs, and then controlling and standardizing automation progress. From problem detection to analysis to problem solving, Closely linked, step by step in-depth evaluation, and finally, automation standardization and the compilation of DFA projects. After completing three major improvements, Then tracking the improved results and results. The original S-shaped line body of the first floor workshop of L Company has been changed into a straight line design. It has obviously advanced a step higher than the old line body in terms of material transportation, one flow production, line balance rate and production efficiency. The field 5S environment has reached a higher level. The productivity target of the annual design has been achieved by 100%, and the line manpower has been improved from 44.5 people to 25.7 people, and the per capita productivity per hour has increased from 16.2 to 31.1.The improvement rate is as high as 92 percent.
