通过对散热器烘焊生产工艺的需求分析，建立了新型烘焊自动线的功能模型与总体结构。针对烘焊过程的非线性、时变性、参数间强耦合和较大的随机性干扰等特点，设计了主烘腔的温度模糊控制器。基于工业控制计算机和可编程序控制器的两级控制，具体开发了新型烘焊自动线。实际运行表明：系统工作可靠，生产效率、产品质量均获得较大提高，能耗显著降低 Through the analysis of the needs of the heat sink production process, a new functional model and general structure of the new automatic welding line were established. According to the characteristics of non-linear, time-varying, strong coupling between parameters and large random disturbance, the temperature fuzzy controller of the main drying chamber was designed. Based on two-stage control of industrial control computer and programmable logic controller, a new automatic welding line was developed. The actual operation shows that: the system is reliable, the production efficiency, product quality are greatly increased, significantly reducing energy consumption
