  • Patent number: 9387991
    Abstract: An apparatus for arranging integrated circuit receiving tubes, the apparatus including a reverse mechanism, a detection element and a discharge mechanism. In use, the reverse mechanism receives a tube and the detection element determines an orientation of the received tube. The reverse mechanism moves to allow the discharge mechanism to receive the tube from itself. If the orientation of the received tube differs from a desired orientation, the movement of the reverse mechanism changes the orientation of the tube before allowing the discharge mechanism to receive the tube. Otherwise, the orientation of the tube is maintained notwithstanding the movement of the reverse mechanism, and is subsequently received by the discharge mechanism. This helps to automatically ensure that all the tubes are received by the discharge mechanism in the same orientation.

  • Patent number: 9193525
    Abstract: An apparatus for handling electronic components on a lead frame. The apparatus including a singulation device configured to singulate the lead frame to thereby separate the electronic components and to position the separated electronic components alternately into at least two layers along different levels; and a guide having a plurality of lanes running along a surface of the guide, the lanes being configured to transport the separated electronic components from a first end of the guide arranged adjacent to the singulation device to a second end of the guide arranged adjacent to an output area. The lanes at the first end of the guide are alternately arranged into at least two layers having respective levels to receive the electronic components from the singulation device, whereas the lanes at the second end of the guide are arranged into a single layer along a common level for transferring the electronic components to the output area.
