【摘要】：H公司新成立涂装车间，在过去一年中，产品质量不稳定，过程单车问题点居高不下；成本管理粗放，年平均单台能耗在500.25元(对标企业单车能耗在320元左右，，超56%)；JPH（每小时生产台数）年平均22，只达到设计产能的63%。针对目前情况，本文就涂装过程的关键要素人、机、料、法、环中的机、料、法、环进行研究，以提高产品实物质量，降低成本，提高劳动生产率。 H公司涂料供应方式虽为化学品集中管理，但存在管理组织不清晰，分工不明确，特殊情况的处理无法可依的情况；因此本课题通过对对化学品集中管理进一步研究，以规范化学品集中管理的操作流程。 涂装环境控制严格程度很大程度上左右喷涂质量。本文就涂装保洁工作进一步研究，并提出现场保洁模块化管理的概念，以提高保洁工作的实际效果。 本文就涂装常见缺陷进行分析研究，在形成机理、分析方法等方面运用质量控制的一些方法，以期能提高涂装缺陷的管控水平，分析出缺陷的形成原因，做到能提前预防，并通过对上述工作的归纳，形成一套解决问题的方法。 涂装设备是否处于良好技术状态，是确保正常涂装生产秩序和涂装质量的关键。本文就一些关键设备原理及管控要点进行研究，对现场管控要点明确化，并形成现场点检和操作文件，进行标准化管理，以形成一个防错的设备管理现场，提高设备的OEE。
[Abstract]:H company has set up a new painting workshop, in the past year, the product quality is unstable, the process cycle problem point is high, the cost management is extensive, the annual average energy consumption of a single unit is 500.25 yuan (the energy consumption of bicycle in the standard enterprise is about 320 yuan, over 56%); JPH (production per hour) an annual average of 22, only 63% of the design capacity. In view of the current situation, this paper studies the key elements of the coating process, such as person, machine, material, method, machine, material, method and ring in order to improve the product physical quality and reduce the cost. Although the supply mode of paint in H Company is centralized management of chemicals, there are some situations where the management organization is not clear, the division of labor is not clear, and the treatment of special circumstances cannot be followed; Therefore, through the further study of centralized management of chemicals, to standardize the operation process of centralized management of chemicals. To a large extent, the quality of spraying is affected by the strict control of coating environment. In this paper, the concept of modular management of field cleaning is put forward in order to improve the actual effect of cleaning work. In this paper, the common defects of coating are analyzed and studied, and some methods of quality control are used in the aspects of forming mechanism, analysis methods, etc., in order to improve the control level of coating defects, analyze the reasons for the formation of defects, and prevent them in advance. And through the induction of the above work, a set of solutions to the problem is formed. Whether the coating equipment is in good technical condition is the key to ensure the normal coating production order and coating quality. In this paper, the principle of some key equipment and the key points of control are studied, and the key points of field control are clarified, and the spot inspection and operation documents are formed, and standardized management is carried out, so as to form an error-proof equipment management site and improve the OEEE of the equipment.
