A method and a system for automatically classifying PCB

The present invention is printed to obtain image information by photographing a printed circuit board, and to determine the identification code and the component information of the printed circuit board with pre-stored comparison at least one of the circuit configuration information and the obtained image information circuit It relates to a method and system for automatic classification board. According to the invention, the printed circuit by taking the storage device, a printed circuit board for storing substrate information recording device for generating the image information and based on the photographed image information, the stored print circuit board information for identifying the printed circuit board includes an assay device, the circuit board information comprises the identification code, the circuit configuration information and composition information of a printed circuit board, wherein the analysis apparatus, obtains the image information from the printed circuit board subject identified by the image pickup apparatus and the obtained image information, but the stored in the storage unit compares the at least one circuit configuration information to determine the identification code and the component information of the identification target printed circuit board, wherein the analysis device comprises the image information with the obtained and characterized by comparing parts of the circuit configuration information stored in the printed circuit board to determine the mutual match That can provide a printed circuit board automatic classification system according to claim. According to another embodiment of the invention, the recording apparatus, the printed circuit storage device for storing the identification code and the component information of the substrate and the photographed image information, the stored printed circuit board by photographing the printed circuit board for generating the image information the identification code and comprising an analysis device by combining the constituent information for generating a printed circuit board information of the printed circuit board, wherein the analysis device is in the extracted parts of features from the captured image information, and the feature portion printed circuit board at least one quantity of the provided conductors, holes and electronic components, to be generated on the basis of size, shape, and arrangement can provide a printed circuit board identification factor generation system according to claim. According to a further embodiment of the present invention, a printed circuit storing the board information, the identification target printed circuit comprising the steps of taking a substrate generate image information and the photographed image information and the stored printed circuit printed on the basis of the circuit board information circuit comprises the step of identifying a substrate, comprising: the circuit board information comprises the identification code, the circuit configuration information and composition information of a printed circuit board, to identify the printed circuit board, and the obtained image information but determines the at least one circuit configuration information identification code and the composition of the identification target printed circuit board information by comparing the stored in the storage device, comparing the obtained image information and the stored parts of characteristics of the circuit configuration information of the printed circuit board to be a substrate Priority method provides a printed circuit, characterized in that for determining cross-match is.
