Abstract: A transfer rack 15 loaded with a seriate number of component supply cassettes 14 to be handled collectively is carried and retained on a truck 61 so that it can be taken in and out of the truck 61. The transfer rack 15 is passed between the truck 61 and a component supply section 8. Thus, the withdrawal of the transfer rack 15 from the component supply section 8 to the truck 61 and the delivery of the transfer rack 15 to the component supply section 8 are executed in a timely manner so as to change the component supply cassettes 14 at the component supply section 8. The transfer rack 15 delivered to the component supply section 8 is positioned by operating an automatic positioning means at the component supply section 8 in a direction in which it is loaded and unloaded and in a direction perpendicular to the direction in which it is loaded and unloaded.

Abstract: Disclosed is a component mounting method. Moved in first and second orthogonal directions is a first mounting head section having first nozzles. The first mounting head is rotated such that the first nozzles rotate and successively pickup components from a first component supply table arranged on one side of a board transfer path. These components are then successively mounted onto a board positioned in the board transfer path. Moved in third and fourth orthogonal directions is a second mounting head section having second nozzles. The second mounting head section is rotated such that the second nozzles rotate and successively pickup components from a second component supply table arranged on an opposite side of the board transfer path. These components are then successively mounted onto the board while positioned in the board transfer path.

Abstract: There is provided a plurality of component mounting apparatuses for sucking a plurality of components by a mounting head section and successively mounting the components onto a board located at a board positioning section. The component mounting apparatuses are arranged in parallel to one another, and a board transfer path is provided so that it penetrates the component mounting apparatuses. Even when the number of components to be mounted onto the board increases, the components are mounted on the component supply tables of the component mounting apparatuses as distributed thereto, and therefore, the whole apparatus is not dimensionally increased. The component supply tables are fixedly installed so as to become free of vibration, and the mounting head section executes the suction and the mounting of the plurality of components. Therefore, the component mounting operation speed can be remarkably increased.

Abstract: In a suction nozzle (20), a sucking surface (60) is made larger in area than a to-be-sucked surface of a component (55) and is configured arbitrarily so long as a width (G1) between mutually-opposed sides parallel to a longer side (110) of the component to be sucked is smaller than a width (G2) in a direction parallel to a shorter side (111) of the component to be sucked. The suction nozzle sucks a component at its sucking surface, with a longitudinal axis (O) of the sucking surface (60) kept inclined with respect to a direction (J) in which the component is supplied.
