  • Patent number: 9851332
    Abstract: A process for determining the quality of a laser weld-seam, whereby a welded plate and a geometrically equivalent non-welded plate are subjected to a physical impact to generate a natural vibration frequency. The natural vibration frequency of the welded plate and the non-welded plate is then measured with an accelerometer and compared. The uniformity of the weld is then determined by the similarity between the natural vibration frequency of the welded plate and the geometrically equivalent non-welded plate.

  • Patent number: 9808933
    Abstract: A robotic system includes a robot, an end-effector assembly disposed at a distal end of a main boom, rotatable parallel frame rails, and tool support branches. Tool modules are connected to a tool support branch and rotatable/translatable with respect to a respective branch axis. A configuration tool has a control block engaged by a wrist of the robot and a work tool. A controller commands the robot to automatically configure the end-effector assembly by adjusting the frame rails and/or tool support branches or tool modules using the work tool, doing so in response to an identified work task. Engagement of the wrist with the tool changer is commanded and the identified work task is executed using the end-effector assembly. A configuration stand may automatically flip the end-effector assembly to a configuration location, command engagement of the wrist with the tool changer, and configure the end-effector assembly.
