摘　　要：为提高铝合金片式散热器涂装工艺的合格率、减少漆膜覆盖缺陷的发生率,引入六西格玛理论中的DMAIC流程改进方法和工具。首先对液滴称重测量系统的可信度进行了分析;然后,通过设计多重DOE试验,确定了影响漆膜覆盖的关键影响因子;最后,基于DOE试验结果,通过实施关键工艺参数优化与质量管理措施,有效提高了涂装质量,减少了材料损失。在这一过程中,精益六西格玛的运用不但将解决涂膜缺陷和波动与提高生产效率有机结合在一起,而且相关测量与工艺参数试验数据也可用于铝合金散热器涂装工艺中漆膜厚度理论模型的建立。In order to improve the qualified rate of aluminum alloy chip radiator coating process and reduce the occurrence rate of coating film defects,the reliability of the droplet weighing and measuring system is first analyzed according to the Minitab mathematical software by introducing the DMAIC process improvement methods and tools in the six sigma theory.Then,by DOE experiments,the key factors affecting the film coverage are determined.Finally,based on the DOE experimental results,through the implementation of key process parameter optimization and quality management measures,the coating quality was effectively improved and the material loss was reduced.Through this process,the application of lean six sigma not only organically combines the solution of film defects and fluctuations with the improvement of production efficiency,but also has certain reference value for the establishment of theoretical model of film thickness in the coating process of aluminum alloy radiators in the future.
