【摘要】：随着现代工业的迅速发展,人们越来越关注生产成本的降低,先进的企业管理理论和实践也在不断的优化和改进,其中以汽车制造业为代表的精益生产方式已得到广泛的认可和应用。许多著名企业陆续引进和应用精益生产方式,并取得了很高的经济效益,如日本丰田汽车公司、美国福特汽车公司、IBM公司等都成功的实施了精益生产方式。成功实施精益生产方式是提升制造企业竞争力的重要保障之一,也是世界一流制造企业的标志之一。首先,本文介绍了精益生产方式的发展概况、国内精益生产应用的状况以及精益生产的原则和改善工具。接着,结合M公司的实际状况和顾客的要求对M公司生产工艺进行分析、诊断,找出M公司生产工艺存在的四个问题:产品换型时间长;生产线不平衡,影响生产效率和整体产能;性能1检测工艺参数不规范;超声波焊接工艺停机率高,易产生不良。通过对这四个问题的深入研究分析,运用SMED快速换型、ECRS原则、工序平衡分析、程序分析、操作分析、动作分析、作业测定、生产匹配等方法提出了一系列的优化措施:实现快速换模;提高生产线平衡率和整体产能;制定有效的性能1检测工艺参数规范;使用双射注塑工艺取代超声波焊接工艺。并予以实施验证,采用实证分析的方法,通过相关数据和比较验证了优化方案的有效性。本文通过以上工作,达到了优化和改进M公司生产工艺、满足顾客要求、提升检测的准确性、降低成本的目的。同时期望通过对M公司生产工艺的研究和优化,能够对与M公司类似的企业的生产工艺建设和优化带来一定的借鉴意义。
[Abstract]:With the rapid development of modern industry, people pay more and more attention to the reduction of production cost, and the advanced enterprise management theory and practice are also constantly optimizing and improving, among which the lean production mode represented by automobile manufacturing industry has been widely recognized and applied. Many famous enterprises have introduced and applied lean production mode one after another, and have achieved high economic benefits, such as Toyota Motor Company of Japan, Ford Motor Company of the United States, IBM Company and so on. The successful implementation of lean production mode is one of the important guarantees to enhance the competitiveness of manufacturing enterprises, and it is also one of the symbols of world-class manufacturing enterprises. First of all, this paper introduces the development of lean production mode, the application of lean production in China, the principles and improvement tools of lean production. Then, combined with the actual situation of M company and the requirements of customers, this paper analyzes and diagnoses the production process of M company, and finds out four problems existing in the production process of M company: long product replacement time; unbalanced production line, affecting production efficiency and overall production capacity; performance 1 testing process parameters are not standard; ultrasonic welding process shutdown rate is high, easy to produce bad. Through the in-depth study and analysis of these four problems, a series of optimization measures are put forward by using SMED rapid transformation, ECRS principle, process balance analysis, program analysis, operation analysis, action analysis, job determination, production matching and other methods: realizing rapid mold change; improving the balance rate and overall production capacity of the production line; formulating effective performance 1 testing process parameter specification; using double injection molding process to replace ultrasonic welding process. The effectiveness of the optimization scheme is verified by empirical analysis, and the effectiveness of the optimization scheme is verified by relevant data and comparison. Through the above work, this paper achieves the purpose of optimizing and improving the production process of M company, meeting the requirements of customers, improving the accuracy of detection and reducing the cost. At the same time, it is expected that through the research and optimization of the production process of M company, it can bring certain reference significance to the production process construction and optimization of similar enterprises with M company.
