Abstract

The invention provides a component mounting and dispatching optimization method for a chip mounter on basis of a quantum neural network. The component mounting and dispatching optimization method comprises the steps of establishing a mathematical model of the sum of paths required by the operation of mounting all components on a printed circuit board (PCB) according to an operating principle of mounting the components by a suction nozzle of the chip mounter, wherein the distances between all the mounted components and different feed tanks are taken as input vectors of the quantum neural network, and all weighting values are set as small random numbers, and given input vectors and target output vectors of a training set are provided; and calculating overall optimal solution of the established mathematical modeling by adopting a three-layer quantum neural network algorithm, thus obtaining an optimized component mounting and dispatching scheme corresponding with the sum of the shortest mounting patches of all the components, the optimal mounting order of all the components, and the arrangement positions of feeders of the components in the feed tanks. The component mounting and dispatching optimization method constructs the component mounting and dispatching mathematical model which takes both the component mounting order and the feeder arrangement positions into consideration, obtains the optimal control on the mounting and dispatching of the components in the PCB, shortens the mounting time of single-end arch components, and enhances the mounting and production efficiency of the components of the chip mounter.
