Abstract: A component mounting method, and an apparatus therefor, which includes the steps of causing a plurality of suction nozzles, supported for intermittent movement along a predetermined path in synchronism with each other, to receive electric components at a component receiving station and then to transport them towards a component mounting station, and effecting both the rectification of the position of each component in two directions perpendicular to each other and the angle adjustment of the respective component during the successive transportation of the components towards the component mounting station. Both the rectification of the position and the angle adjustment of each component are carried out while the associated suction nozzle is held still at a certain station, and electric characteristics of each component are checked during the rectification.

Abstract: Disclosed is an apparatus for holding an electronic part including a rod coupled to a part-absorbing nozzle at one end thereof and coupled to a vacuum device at the other end portion thereof, the rod being axially movable. Also included is a sleeve member movable along the axis of the rod in response to the movement thereof. A pair of chucking jaws for chucking the electronic part are coupled through a transmission mechanism to the sleeve member. The transmission mechanism comprises a pair of curved levers each providing a connection between the chucking jaws and the sleeve member and a pair of guide members which are respectively engaged with the pair of chucking jaws and radially extend at right angles to the axis of the rod, and is arranged to allow the pair of chucking jaws to be moved at right angles to the axis of the rod member in opposite directions to each other in response to the movement of the sleeve member.
