基于轨道交通产品制造过程的SPC方法研究

SPC method research based on rail transit product manufacturing process

随着德国工业4.0的推出以及"中国制造2025"的战略部署,越来越多的企业引进智能生产线并逐步投入生产,智能生产线可以实现产品关键质量特性的自动化监测与数据采集。导入统计过程控制(SPC)方法,实现检测数据的自动分析和预警控制,对产品质量控制有着重要意义。文章结合SPC的基本理论,以IGBT导热硅脂涂覆管控为案例,展开SPC的深入研究,并通过后期的实践应用实现生产过程实时控制及过程优化,提高过程的稳定性。

With the introduction of German industry 4.0 and the strategic deployment of made in China 2025, more and more enterprises introduce intelligent production line and put it into production step by step. Intelligent production line can realize automatic monitoring and data acquisition of key quality characteristics of products. The introduction of statistical process control（SPC） method to realize automatic analysis and early warning control of test data is of great significance to product quality control. Based on the basic theory of SPC, this paper takes the control of IGBT thermal conductive silicone coating area as an example to carry out the in-depth study of SPC, and realize the real-time control and process optimization of the production process through the later practical application, so as to improve the stability of the process.
