ABSTRACT:
An automatic electronic parts-mounting apparatus mounts chip-like electronic parts supplied from a parts feeder at predetermined positions on a printed substrate. The parts-mounting apparatus accurately and quickly determines angular positions of the electronic parts by rotating adsorptive nozzles. The adsorptive nozzles are capable of adsorbing the electronic parts one by one, and each nozzle is connected to a rotor of a nozzle-rotating motor for rotating the adsorptive nozzle within a plane that is perpendicular to an axis of the adsorptive nozzle. The rotor is rotated in accordance with the adsorbed state of the electronic parts to make fine adjustment for determining the angular position.
