  • Patent number: 8985305
    Abstract: A vibration feeding apparatus comprises an alignment track that is operative to receive electronic components and to arrange the electronic components in a desired orientation by vibrating and accelerating the electronic components located on the alignment track. An inspection station rejects electronic components that are not in the desired orientation onto a reject track for reintroduction to the alignment track. A spreading unit adjacent to the alignment track then transfers rejected electronic components from the reject track to the alignment track for arranging the electronic components in the desired orientation.
    Type: Grant

  • Patent number: 8733539
    Abstract: A vibration feeding apparatus comprises a receptacle for holding and conveying components, and first and second linear motors coupled to the receptacle. The first and second linear motors are spaced from each other and have respective coils that are aligned parallel to each other. The first and second linear motors are operative to be driven at a first operation mode whereby to impart rotary vibration to the receptacle, and at a second operation mode whereby to impart linear vibration to the receptacle.
