摘　　要：针对全视觉贴片机的贴装顺序优化问题,首先通过建立贴装时间的数学模型,提出最大化同时取料次数和合理安排取贴循环顺序这一策略;随后,通过对数学模型的分析,提出了分别运用启发式搜索算法和单亲进化的遗传算法来解决同时取料次数的优化问题及取贴循环的优化安排问题;实验结果证明,所提算法能有效提升贴片机的贴装效率,减少贴装时间。A mathematical model is given to describe the assembly time of PCB. The solution as minimizing the number of pickups and arranging the work cycles properly is obtained. An algorithm based on Heuristic Scan is presented to solve minimizing the number of pickups problem. Also a PEGA algorithm is presented to solve the work cycles arrangement problem. And experiment shows that this algorithm can solve the problem effectively.
