A method for identifying absorption of parts of a chip mounter is provided to prevent an error of a printed circuit board and a reduction of a production yield due to the missing of the parts by recognizing the absorption of the parts on a nozzle. A method for identifying absorption of parts of a chip mounter includes the steps of: picking up the parts by a nozzle(S10); acquiring an image having the nozzle by a photographing apparatus located on a lower part of the nozzle(S12), and then indicating an inspection region(S14); performing a binarization through thresholding for the inspection region(S16); extracting information for an outer edge region within the inspection region by performing a labeling work in the inspection region where the binarization is carried out(S20); separating an inner region by performing the binarization for the outer edge region(S22); comparing a characteristic value of an internal region with the outer edge region(S24); and determining whether the parts are absorbed on the nozzle by analyzing whether the comparison result is mated with predetermined reference data of the nozzle(S26).
