  • Patent number: 10112307
    Abstract: A part holding assembly, an assembly system and a method of positioning a first part are disclosed. The part holding assembly is coupleable to a support structure. The part holding assembly includes a base adapted to be coupled to the support structure. The part holding assembly also includes a first pin extending outwardly away from the base to a distal end that is spaced from the base. The base is movable to position the first pin relative to a first part and to insert the distal end of the first pin through a first hole of the first part to locate the first part. The part holding assembly further includes a first magnet adjacent to the first pin. The first magnet is selectively magnetized to selectively secure the position of the first part relative to the base.

  • Patent number: 8033002
    Abstract: An end-of-arm tool having a workpiece interface tool is attachable to an articulable robotic arm. The end-of-arm tool can be configured by engaging an adjustable modular unit including a swing arm, a cylinder, and a workpiece interface tool to a rail element of the end-of-arm tool. The adjustable modular unit machine-slides in the rail element to a preferred x-axis position, machine-pivots to a preferred angular orientation, and machine-extends along a longitudinal axis of the cylinder to a preferred z-axis position, and machine-rotates to a preferred rotational angle about the z-axis.

  • Patent number: 8025323
    Abstract: A ratcheting end-of-arm (EOM) tool having a spring-loaded level compensator, a distally mounted gripper, and a ratcheting mechanism. In operation, upon a selectively adequate contact between the gripper and a payload, the ratcheting mechanism is engaged which holds the position of the gripper with respect to the robot arm at a fixed position, independent of spring biasing. Upon conclusion of robotic movement of the payload, the gripper is deactivated, the ratcheting mechanism is disengaged, and the spring returns the ratcheting EOA tool to its nominal configuration.

  • Patent number: 7963578
    Abstract: An integrated vacuum and magnetic gripper includes a rigid housing defining an internal chamber, and a flexible vacuum cup operatively connected thereto. A vacuum cavity is defined by the vacuum cup and a vacuum source is configured to reduce pressure in the vacuum cavity. A permanent magnet is disposed within the rigid housing, and a magnet release mechanism is configured to selectively render the magnet incapable of exerting sufficient force to hold the work piece. A pole plate may be interposed between the internal chamber and vacuum cavity, such that the pole plate forms a portion of the internal chamber and may act to provide friction on the work piece. A method of using the gripped includes operating at high acceleration while the vacuum gripper is monitored as fully operational and operating only at lower acceleration while the vacuum gripper is not fully operational.
