【摘要】：随着我国经济的持续快速发展,中国汽车、摩托车、电动助力车、通信、信息、电力等基础产业发展十分迅速,这些行业在我国处于一个高速成长期,对蓄电池的需求日益增长,蓄电池工业呈持续、快速增长趋势。D公司作为蓄电池行业内领军企业,多年来,公司始终专注于通讯、电力、铁路、航空、军事、民用等领域,创造了专家营销、绿色营销的模式。近年来,行业内环保、节能减排工作的深化推进,客户对产品的需求越来越趋向于个性化、定制化都对公司大规模生产情况下的成本管控带来巨大的挑战。企业人力成本逐年上升与产品价格逐年下降,使得企业赢利空间越来越小。因此,如何不断改进产品质量、减少内部质量损失、降低生产成本及提高客户满意度是当前D公司关注的核心问题。本文以现代质量改进技术为理论依据,基于质量管理方法,以D公司生产过程为研究对象,首先对D公司目前的质量管理现状进行论述,对生产过程中的产品质量问题进行分析,结合Pareto图,确定当前影响D公司产品质量及成本管控的主要工序一板栅铸造工序。其次,通过直方图、帕累托图找出影响板栅铸造质量缺陷的主要因素-合金渣多,确定研究课题。随后组建板栅质量改进项目团队,开展QC活动,采用头脑分暴法、因果图、直方图等相关统计技术及质量分析改进工具对影响蓄电池板栅合金出渣率的问题进行了原因分析,结合对现场的深入调查、生产验证、实验设计等方法找出主要影响因素,优化现行工艺参数,并对“人、机、料、法、环”等方面影响因素进行了改进对策的实施和验证。最后,结合对此次质量改进项目改进的实施过程及取得的成效,总结质量改进活动的经验,并指明了下一步改进的方向。本文的研究结果不仅为D公司质量改进活动制定了解决方案和实施策略,对公司提高产品质量具有重要作用。同时也为类似蓄电池制造企业实施质量改进提供了可借鉴的经验和操作方法。
[Abstract]:With the sustained and rapid development of China's economy, the basic industries of China, such as automobiles, motorcycles, electric boosters, communications, information, electricity, and so on, are developing very rapidly. These industries are in a period of rapid growth in our country. The demand for batteries is increasing day by day, and the battery industry is growing continuously and rapidly. As a leading enterprise in battery industry, company D has been focusing on communication, power, railway, aviation, military, civil and other fields for many years. Created expert marketing, green marketing model. In recent years, with the deepening of environmental protection, energy saving and emission reduction in the industry, customers' demand for products is becoming more and more individualized. Customization brings huge challenges to the cost control of the company under the circumstance of large-scale production. The enterprise labor cost rises year by year and the product price drops year by year, which makes the profit space smaller and smaller. Therefore, how to continuously improve product quality, reduce internal quality loss, reduce production costs and improve customer satisfaction are the core issues concerned by D Company. Based on the theory of modern quality improvement technology and the method of quality management, this paper takes the production process of company D as the research object, and discusses the current situation of quality management in company D at first. Based on the analysis of product quality in production process and Pareto diagram, the grid casting process, which is the main process that affects the product quality and cost control of D Company, is determined. Secondly, through histogram and Pareto diagram, we find out the main factors that affect the quality defect of grid casting-alloy slag, and determine the research subject. Then a grid quality improvement project team was set up to carry out QC activities. The causes of the problems affecting the slag yield of the battery grid alloy were analyzed by using the relevant statistical techniques, such as brain-splitting method, causality diagram and histogram, and quality analysis and improvement tools. Combined with the field investigation, production verification, experimental design and other methods to find out the main factors, optimize the current process parameters, and "people, machines, materials, methods, ring" and other aspects of the impact factors to improve the implementation and verification of countermeasures. Finally, combined with the implementation process of the quality improvement project and the results obtained, the experience of the quality improvement activities is summarized, and the direction of the next improvement is pointed out. The results of this paper not only make a solution and implementation strategy for the quality improvement activities of company D, but also play an important role in improving the quality of products. At the same time, it also provides experience and operation methods for similar battery manufacturing enterprises to implement quality improvement.
