Abstract: Each of a plurality of suction nozzle sections 20 provided about the outer circumference of an intermittently rotating head section 21 comprises a plurality of nozzle tip sections 10 for picking up electronic components 22 by suction, these nozzle tip sections 10 being connected to a rod section 4, which is driven to rotate by a motor 1. A cylindrical cam section 8having a cam surface 8a and being able to rotate relative to the rod section 4 is provided such as to encase the nozzle tip sections 10, and one ends of the nozzle tip sections 10 engage with the cam surface 8a of the cam section 8 via rollers 6, whereby the nozzle tip sections 10 are movable in a vertical direction. On the outer side of the cylindrical cam section 8, a stopper section 12 is provided for halting temporarily the rotation of only the cylindrical cam surface 8.

Abstract: An electronic component feeder is provided for feeding electronic components in their stable position into an electronic component mounting apparatus and allowing the taking up of a top tape with high stability thus increasing the speed of component mounting action. As the top tape (4) is being taken up on a reel (42), a shutter (34) moves backward together with a slit (51) provided integral on the shutter (34). The turning in the tape take-up direction of the reel (42) is driven by the restoring force of a return spring (39). When the reel (42) has completed its take-up motion, the electronic component (1) can be picked up at a component pick-up location with the shutter (34) staying backward. A stationary roller (31) is provided between the slit (51) and the reel (42) and a movable roller (32) is provided for keeping the length of the top tape (4) between the slit (51) and the stationary roller (31) substantially constant.

Abstract: A method for mounting components, includes a first step for feeding to a component feed unit a plurality of stacked-in-stages trays on which components are accommodated, a second step for taking out the components of a Top-stage tray sequentially one by one to mount them onto a board, and a third step for, when the components on the tray are exhausted, removing the empty top-stage tray, and then returning to the second step. An apparatus for mounting Components includes a component feed unit for feeding a plurality of stacked-in-stages trays on which components are accommodated, and a pickup device which can selectively hold either a component pickup nozzle or a tray transfer nozzle. The pickup device is movable between the component feed unit and a specified position of a substrate or between the component feed unit and a tray removal box. A nozzle replacement unit is provided for performing replacement of the pickup nozzle and the tray Transfer nozzle.
