Abstract

The invention discloses an optimization method for balancing the loads of multiple chip mounters in an assembly line in PCB assembling technology. The method comprises steps of describing and analyzing an optimization problem of a PCB assembly production line; establishing a load balancing mathematic model according to the description and the analysis of the optimization problem; designing an algorithm according to the solution characteristic of the mathematic model to obtain a load-balanced component mounting sequence of the chip mounters; applying the load-balanced component mounting sequence to a production line control system in order to enable the chip mounters in the production line to mount components according to an optimum scheduling mode, wherein the algorithm is an intelligent optimization algorithm combining a cuckoo search algorithm with a particle swarm optimization algorithm. The method solves a load-balanced optimized scheduling mathematic model of the chip mounters in the production line and acquires a globally-optimum component mounting scheduling scheme by using the improved cuckoo search algorithm so as to balance the loads of the chip mounters and increase the efficiency of the production line.

Description

technical field [0001] The invention relates to an intelligent scheduling optimization method for a PCB board (printed circuit board) assembly production line, belonging to the technical field of intelligent optimal scheduling and control of production systems. Background technique [0002] The surface assembly production process is a key process of my country's electronic information manufacturing industry, and the core research results in this area are rarely published internationally. The domestic exploration of key common theoretical issues and implementation technologies has just started, and these have become constraints for my country. The electronic information industry catches up with the bottleneck of the international advanced manufacturing level. [0003] Printed circuit board (PCB board) assembly is the core process of the surface assembly production line. It is to assemble electronic components on the printed circuit board to realize the interconnection of elect...
