Abstract


Surface mount technology (SMT) is the mainstream technology in today 's printed circuit board (PCB) production . The placement machine is the most critical equipment in the SMT system , the assembly process is the bottleneck of the production efficiency of the entire system . Most of the previous studies gantry -style and turret placement machine , instead of the current mainstream high-speed multifunction placement machine , such Mounter typical horizontal rotary placement machine . Mounter Mount Rotary will level process optimization to start the study. This article studies the the horizontal rotary Mounter structure characteristics and placement process , analyze and summarize the factors that affect the efficiency of the placement machine , the establishment of a practical the placement machine placement process optimization mathematical model , and is divided into The distribution of the feed trough and placement sequence optimization in two steps to solve this problem . First intermediate files as the data source placement machine optimization , placement machine optimization independent of the the various heterogeneous electronic design environment ; Second , based on the characteristics of the components , packet classification based on the optimization of the components the allocation for the trough ; Finally, the actual placement process, improved genetic ant colony algorithm , the placement sequence optimization method based on improved algorithm design . Simulation results show that the optimization scheme proposed in this paper , not only conforms to the the Mounter actual work , shortening the PCB assembly time , improve the efficiency of the placement of the placement machine . The idea of ??optimization and design of algorithms used in this paper also has some reference significance for other types of placement machine . Subsequent research will mount equipment level optimization of production lines optimized combination of online multi- Mounter balance that a production optimization , to improve the efficiency of the production line .
