Abstract: A component mounting machine includes a part camera in which a suction nozzle for sucking a component P and a fiducial mark are provided on a head, a sub-lens is installed in a visual field of a lens, the component is imaged through a main lens, and it is possible to image the fiducial mark through the lens and the sub-lens. Distortion correction values of the main lens portion are measured, distortion correction values of the sub-lens portion are measured, and the distortion correction values are stored in advance as a distortion correction table. During component mounting, when the component P which is sucked by the suction nozzle and the fiducial mark are imaged at the same time by the part camera, the obtained image is corrected using the distortion correction table, and a suction state of the component P is detected based on the corrected image.

Abstract: A component-mounting machine which prevents collision of a sucked component with an optical system capturing images of an imaging reference mark and the sucked component simultaneously when a component-mounting head moves to capture images. A sucked-component position detection device includes an imaging unit, which is installed on a side of a base of the component-mounting machine and has an image sensor and a lens; and a first refraction member which alters a first focal position of a first optical path that connects the image sensor, the lens and the imaging reference mark. The first refraction member is installed on the side of the base and at a position lower than a second focal position of a second optical path that connects the image sensor, the lens and the sucked component.

Abstract: A circuit-substrate-related-operation performing apparatus for performing a circuit-substrate-related operation which is an operation on a circuit substrate, including: a plurality of heads including at least one work head and at least one detection head; a head holding device configured to hold, at a holding portion thereof, one of the plurality of heads; a moving device configured to move the head holding device; a head stock device in which the plurality of heads are stocked; and a controller configured to control the circuit-substrate-related-operation performing apparatus, wherein the controller includes a head attachment control portion configured to control the moving device and the head holding device such that the head holding device is moved to a set position which is set with respect to the head stock device and such that an arbitrary one of the plurality of heads is held by the head holding device.

Abstract: A component-mounting machine which prevents collision of a sucked component with an optical system capturing images of an imaging reference mark and the sucked component simultaneously when a component-mounting head moves to capture images while lightening the component-mounting head. In the component-mounting machine of the present invention, a sucked-component position detection device includes an imaging unit, which is installed on a side of a base of the component-mounting machine and has an image sensor and a lens; and a first refraction member which alters a focal position of a first optical path that connects the image sensor, the lens and the imaging reference mark. The first refraction member is installed on the side of the base and at a position lower than a focal position of a second optical path that connects the image sensor, the lens and the sucked component.
