ELECTRONIC COMPONENT CONVEYING EQUIPMENT AND ITS CONTROL METHOD

WIPO Patent Application WO/2007/063641

A1

Electronic component conveying equipment which can discharge all electronic components from the through hole of a conveyance member when operation is stopping while suppressing occurrence of rejective component. Its control method is also provided. When the operation of the electronic component conveying equipment is stopped, negative pressure state in the through hole (3) is stopped and compressed air stronger than when the electronic component conveying equipment is operating is injected from the injection outlet (11) of a compressed air injection mechanism (10). Consequently, an air curtain is formed at the opening of the through hole (3) on the guide member (5) side, thus preventing an electronic component (30) from entering the through hole (3). Electronic components (30) remaining in the through holes (3) located on the downstream side of the outlet (11) in the conveying direction (X) are conveyed up to a measuring section where they are measured and discharged by a discharge mechanism before the rotation of the conveyance member (2) is stopped.
