【摘要】：装配活动是产品生产的重要环节，装配环节的质量对产品最终质量有着极大的影响。实施信息化软件能够帮助企业建立实时、有效的装配质量信息平台。本文主要研究了如何通过制造执行系统改进装配生产过程的质量控制。首先分析了装配质量控制对制造执行软件的需求以及功能目标，然后从功能框架和技术框架两个方面说明了MES产品如何消除企业质量管理中的“信息断层”与“信息孤岛”问题，并介绍了KMMES主要功能模块以及支持层、应用层和访问层三层技术框架结构。采用质量活动履历表作为质量信息的载体，集成了装配生产、质量检验等过程产生的质量信息，方便了质量信息的采集、存储与调用。文中构建了基于质量活动履历表的车间质量信息传递模型，建立了质量活动履历表与产品BOM、工艺BOM以及质量BOM相互关联，，实现了质量活动履历表的生成与调用。通过对生产主计划管理，说明了制造执行系统中质量追溯的实现流程，研究了以下三个方面：通过质量活动履历表追踪生产装配的过程；制造执行系统与排产软件的集成；条码标签识别生产物料，分别解决了质量追溯实现中质量信息集成、生产过程监控和物料批次识别这三个关键问题。以装配质量数据统计分析和物料齐套性管理为例，说明了论文相关研究成果在KMMES的质量管理、生产监控等功能模块中的实际应用过程。
[Abstract]:Assembly activity is an important part of product production. The quality of assembly link has a great influence on the final product quality. The implementation of information software can help enterprises to establish a real-time and effective assembly quality information platform. This paper mainly studies how to improve the quality control of assembly production process through manufacturing execution system. Firstly, the requirement and function goal of assembly quality control for manufacturing execution software are analyzed. Then it explains how to eliminate the problem of "information fault" and "information island" in enterprise quality management from two aspects of function framework and technical framework, and introduces the main function module and support layer of KMMES. Application layer and access layer three-tier technical framework. The quality activity resume is used as the carrier of quality information, and the quality information produced by assembly production, quality inspection and other processes is integrated, which facilitates the collection, storage and transfer of quality information. In this paper, a workshop quality information transfer model based on quality activity resume is constructed, and the correlation between quality activity resume and BOM, process BOM and quality BOM is established, and the generation and transfer of quality activity resume are realized. Through the management of production master plan, the realization flow of quality traceability in manufacturing execution system is explained, and the following three aspects are studied: tracking production assembly process through quality activity resume, integration of manufacturing execution system and production scheduling software, The bar code label is used to identify the production materials, which solves the three key problems of quality information integration, production process monitoring and batch identification in the realization of quality traceability, respectively. Taking the statistical analysis of assembly quality data and the material consistency management as examples, the paper illustrates the practical application process of the related research results in the function modules of KMMES, such as quality management, production monitoring and so on.
