Abstract: A three-dimensional measurement device includes: an irradiator that emits a predetermined light; an optical system that splits the predetermined light into two lights, irradiates a measurement object with a measurement light and irradiates a reference plane with a reference light, and emits a combined light; an imaging device that takes an image of the combined light and obtains an interference fringe image; an objective lens for the measurement light that directs the measurement light toward the measurement object; an objective lens for the reference light that directs the reference light toward the reference plane; an imaging lens that forms an image of the combined light on the imaging device; and a control device that executes three-dimensional measurement of a measurement area on the measurement object based on the interference fringe image.

Abstract: A three-dimensional measurement device includes: an illuminator that irradiates a measured object with a predetermined light; an imaging device that comprises: an imaging sensor displaceable at least in a vertical direction; and a both-sided telecentric optical system that causes the imaging sensor to form an image of a predetermined area on the measured object irradiated with the predetermined light; a conveyor that moves the illuminator and the imaging device relative to the measured object; and a controller that: executes three-dimensional measurement of a predetermined measurement object on the measured object, based on the taken image; measures a height of the predetermined area at least at a time prior to imaging of the predetermined area under the predetermined light; and changes a height position of the imaging sensor based on a measurement result to adjust an interval between the predetermined area and the imaging sensor to a predetermined distance.

Abstract: A component mounting system includes: a component mounting machine that mounts an electronic component having a predetermined electrode portion on a solder printed on a substrate, the electronic component being fixed to the substrate with a thermosetting adhesive; and an adhesive inspection device. The component mounting machine: sets, with regard to the electronic component to be fixed with the adhesive that cures at a temperature lower than a melting temperature of the solder, a target mounting height along a height direction perpendicular to a face of the substrate on which the adhesive is applied; and mounts the electronic component at the target mounting height. The target mounting height is: an ideal mounting height based on design data; or a height lower than the ideal mounting height by a value that corresponds to a sinking of the electronic component as a result of melting of the solder.
