A pallet-storing block of an electronic component-mounting apparatus stores a plurality of pallets each carrying thereon a tray containing a large number of electronic components. A desired pallet selected from the pallets is moved along a transfer path, in a manner such that the desired pallet is advanced to be introduced into a pickup area which extends to cover almost all of the transfer path or withdrawn from the pickup area into the pallet-storing block. Desired electronic components are sequentially picked up from the desired pallet introduced into the pickup area and mounted on a circuit board. The desired pallet is moved to a desired position within the pickup area.

Electronic component-mounting apparatus and component-feeding device therefor

Electronic component- mounting apparatus and component-feeding device therefor

A component-mounting block of an electronic component-mounting apparatus has mounting heads installed thereon. Each mounting head has a nozzle-replacing device for replacing at least one selected sucking nozzle by at least one other sucking nozzle to be newly selected. The replacement is possible during travel of the component-mounting block between a mounting position and a sucking position effected by a X-Y moving stage. At least one mounting head carries at least one sucking nozzle rotatable about a vertical axis of a nozzle holder. The mounting head has the nozzle holder, and an engaging member holder. Sucking nozzles are circumferentially arranged about the vertical axis of the nozzle holder and vertically retractably held by the nozzle holder. The engaging member holder holds engaging members which engageably face the nozzles. The nozzles are engaged with the engaging members when the holders are relatively vertically moved toward each other, and are retracted when the holders are moved away from each other. The engagement can be prevented. A selected engaging member is prevented from engaging with a corresponding sucking nozzle by rotating the holders about the vertical axis. Alternatively, at least one nozzle is disengaged from a corresponding engaging member at a desired rotational angle of the holders.

Electronic component-mounting apparatus and mounting head device therefor

There is provided a component-feeding device for an electronic component-mounting apparatus which has a main block for carrying out electronic component-pickup and mounting operations. The component-feeding device selectively transports a plurality of pallets on each of which at least one tray containing a number of electronic components is placed, to a pickup position for picking up supplied one of the electronic components. A selected one of the pallets is vertically transported selectively to different levels according to a height of the at least one tray on the selected one of the pallets. The selected pallet vertically transported to the selected level is horizontally transported to the pickup position.
