  • Patent number: 11573267
    Abstract: An electronic component handling apparatus handles a DUT and includes: an acquiring device that acquires current three-dimensional shape data of a DUT container having a plurality of accommodating portions each capable of accommodating the DUT; and a computer device that: calculates a first correction amount from the current three-dimensional shape data and corrects the current three-dimensional shape data based on the first correction amount; extracts, from the corrected three-dimensional shape data, at least one of a height and a slope of each of predetermined regions of the DUT container; and determines an accommodation state of the DUT based on an extraction result. The first correction amount represents at least one of a movement amount and a rotation amount in a planar direction of the current three-dimensional shape data with respect to an initial state of the DUT container set in advance.
