ABSTRACT:
A belt feeder for the rapid and successive in-line transportation of small electronic components. The belt feeder has an inclined dispensing portion with at least one dispensing lane, a conveyor portion having an intermittently moving conveyor belt and at least one conveyor guide lane superposed above the conveyor belt, and a receiving nose structure having at least one nest structure mounted thereon at the end of the conveyor belt and forming a nest. The inclined track is positioned adjacent and above the conveyor track to allow the components enough space to be successively dispensed to the conveyor belt from the dispensing lane and into the conveyor guide lane where the component is intermittently carried forward by the conveyor belt until it comes to rest within its nest. A sensor system repetitively starts then stops the conveyor belt in response to the action of a pick and place or robotic assembly machine so that when the component is picked, leaving an empty nest, the next component is advanced into the nest. A solenoid-operated reciprocating sub-structure is used to intermittently move the nest structure out, away from the component in the nest and then back to receive the next component. A component brake device may be attached to the reciprocating sub-structure to provide braking of the components on the conveyor belt when the nest structure is moved out, away from the component receiving point. An optional component brake assembly superposed above the conveyor belt is also described.
