  • Patent number: 6357108
    Abstract: A depaneling system having multiple router stations. A feeder station in the dual routing station receives a panel from a feeder station. The feeder station then selectively delivers the panel to one of the router stations. The router station then severs all of the connections between the panel and the PC boards. The multiple router stations can also share a common router that is used by each station to sever the connections. In order to use a common router the router station have a movable receiving base which moves along a first axis. The router then moves along the second axis. The router and receiving base are then moved along the first and second axises independently to sever the connections.

  • Patent number: 6192563
    Abstract: A system having improved cycle time for removing PC boards from a connected panel. In accordance with the present invention, a pair of walking clamps are used to receive a panel from a subsequent processing system, and a movable receiving nest is used to provide the PC boards to a subsequent processing station. The processes of receiving a panel, depaneling the PC board, and delivering the PC boards do not use common components and are able to operate independently and concurrently to reduce idle time in the system and improve the cycle time. The present invention also provides a secondary vacuums which removes debris from the PC boards as the PC boards are being transporting to a subsequent processing system to improve the removal of debris.

  • Patent number: 5894648
    Abstract: Individual printed circuit boards are routed from a panel comprised of an array of printed circuit boards. The individual printed circuit boards are moved as a group, after being routed from the panel, to a registration nest for holding the individual printed circuit boards. The printed circuit boards rest in the registration nest until a subsequent processing station is ready to receive a printed circuit board. At the appropriate time, each printed circuit board is moved one at a time to a subsequent processing station. A second group of printed circuit boards is routed from a second panel while the first group of printed circuit boards rests in the registration nest and is moved one at a time to the subsequent processing station. A sensor reads features on the panel or on individual printed circuit boards and the routing program is modified or stopped in response to certain panel features.
