Efficiency Improvement Of CELL Manufacture Flow Based On OEE

The article Bases on Thin Film Transistor Liquid Crystal displays manufacturing process of important equipments as the research object, to study to improve the equipment. Efficiency. For many years I have been engaged in manufacturing in TFT-LCD, know the first line of manufacturing sector has long been a puzzling problem that it can not enough to satisfy customer demand and to take huge tactics to improve output, only to improve capacity to meet customer demand, however equipment production efficiency's low is the bottleneck of restricting output of the company, now a shift to reform, has made by previous single shifts into two shifts namely often work days turned white evening twenty-four hours working condition.TTF-LCD manufacturing process by anterior Array (Array), the panel assembly (posterior segment Cell), Module assembly (Module) three modules. panel assembly module (CELL) equipment is one of the highest value, and its process also complex, so CELL is heart of tft-lcd manufacturing CELL manufacturing process, once part of any a work station when machine immediately will spread to other workers standing stock outs. So further research TTF-LCD CELL of the equipment manufacturing efficiency improvement is great significance. Equipment integrated Overall Effectiveness efficiency provide a direction, OEE is a useful analysis tool, it put Equipment comprehensive efficiency three index (time efficiency by the performance efficiency, quality and efficiency of the product, reflected) and the three indexes level for many time loss, subdivide classified as six time loss (Equipment failure time loss, installation debugging time loss, idling short outage losses, speed reduce losses, processing waste maintenance loss, initial bad losses), its analysis method is through the OEE percentage of tracking, understand the cause OEE rating low is which of the three indexes by above is an indicator, and again from loss caused by the loss of the high proportion of production, then database query weight distribution, again according to Pareto principleto improve the principle. According to this logic can deep dig out the hidden under a rock in calm water where the equipment time lost, low efficiency because of the loss of which part caused from which aspects should hand, so that the most obvious improvement since grasp key it.And the analysis of the process is OEE daily equipment loss analytical, let equipment technical personnel more clearly planning maintenance work, timely processing equipment failure and various plans with the planned downtime, effective control of productivity loss brought by downtime, then multi-dimension data analysis technology using the proposed equipment efficiency improvement measures, reduce component failure frequency. Through effective improvement measures to reduce equipment maintenance time, increase productivity and improve the equipment comprehensive use efficiency.In recent years, With China's rapid development of the TFT manufacture industry, the equipment availability has become one of the important topics managers' attention, Foundry industry, changing to the fierce market place with each passing day, in addition to enhancing the competitiveness of foreign R & D, still need improve the comprehensive efficiency to improve equipment capacity, reducing equipment use quantity, thereby reducing maintenance cost。This article mainly to company tft-lcd Cell manufacturing process of discrete manufacturing sections as a starting point, the analysis of using OEE, relieving production bottleneck from finding improve point to increase capacity for the CELL production to provide an effective equipment management approach. The company's present situation should start from global equipment efficiency improvement, can reduce cost, improve equipment, make enterprise capital operation benefit keep vigorous development.Through the research achievement, use IE techniques to analyzes and improve, to minimize the cost of inputs to enable enterprises to gain maximum benefit, avoid the use of large funds to purchase new equipment to increase capacity and enhance the market competitiveness of LCD, to get more orders for enterprise to obtain greater profits。...
