Abstract
An apparatus for feeding plate-form parts such as lead frames used in, for example, semiconductor assembling machines including a plurality of frame feeder which have upper and lower claws for feeding the plate-form parts, a slider to which the frame feeder is mounted, a moving piece connected to the slider, a drive shaft screw-engaged with the moving piece, and a claw moving motor which rotates the drive shaft and therefore moves the moving piece. The feeding apparatus of this invention allows the drive shaft which moves the frame feeder to be shorter than in conventional apparatus so that each frame feeder can be fed with high precision.
