ABSTRACT: 在转塔式贴片机的印製电路板PCBPCB组装的集成最佳化模型,对蚁群算法进行了改进,提出了相互通信的最大–最小蚂蚁算法,用两种不同职能的蚂蚁相互协作,以元件组装顺序来驱动供料器布置,引导蚂蚁实现元件贴装顺序的最佳化,而执行蚂蚁根据引导蚂蚁选择元件的结果来实现供料器布置最佳化。算法可对元件贴装顺序和供料器的布置进行同时最佳化,从而提高转塔式贴片机上The component placement sequence and feeder arrangement are the critical factors determining assembly time of chip shooter (CS) machine. In addition, the different size of component and different arrangement strategy affect the feeder arrangement and component placement sequence. Based on the engineering analysis, an integrated optimization model of printed circuit board (PCB) assembly for CS machine is established. According to the parallel placement character of CS machine, “Max-Min Ant Colony Algorithm with Communication function” is designed based on traditional Ant Colony Algorithm. The idea that two ants with different duties collaborate to solve the optimization problem is presented. Guide ants optimize placement sequence while executant ants optimize feeder arrangement according to the components placement sequence. The component placement sequence and feeder arrangement are optimized simultaneously.
