Abstract: A component assembly system comprises a first robot arm having a first end-of-arm tool mounted thereon and adapted to grasp a first subcomponent; a second robot arm having a second end of arm tool mounted thereon and adapted to grasp a second subcomponent. A system controller is adapted to control the first and second robot arms and first and second end-of-arm tools to position the first and second subcomponents relative to one another. A first interlocking mechanism is mounted onto the first end-of-arm tool and a second interlocking mechanism is mounted onto the second end-of-arm tool, wherein the first and second interlocking mechanisms engage one another and lock the first end-of-arm tool to the second end-of arm tool, thereby locking the first and second subcomponents into an initial position relative to one another.

Abstract: A welding block for a welding system secures together first and second components of a workpiece for a motor vehicle to reduce distortion of the first and second components during a welding process. The welding block includes a jig mechanism that has a proximal surface for receiving a load from an arm of the welding system. The jig mechanism further includes a distal surface for engaging the first component and securing the first and second components to one another during the welding process. The jig mechanism defines a passage, such that heat flows from the distal surface to a coolant flowing through the passage. The welding block further includes a sensor coupled to the jig mechanism for detecting a measured variable associated with at least one of the first and second components.

Abstract: A clamp system and method for measurement and control of welding a first substrate to a second substrate is provided. The system comprises a squeeze clamp having to a first end and a second end. The system further comprises a motor connected to the squeeze clamp such that the first and second ends are movable to clamp the first substrate to the second substrate. The system further comprises at least one of an electromagnetic flux sensor, a current sensor, a position sensor, and a gap sensor disposed on one of the first and second ends for determining a first measured variable between the first and second substrates. The system further comprises a controller to control the motor to clamp the first substrate to the second substrate based on the first measured variable. The controller is in communication with the electromagnetic flux sensor, the current sensor, and the gap sensor.

Abstract: A releasable adhesive system for joining a first surface to a second surface. The system includes a primary material having a first portion including at least one first-portion molecule configured to be positioned parallel with at least one first-surface molecule of the first surface, and a second portion, opposite the first portion, including at least one second-portion molecule configured to be positioned parallel with at least second surfaced one molecule of the second surface. The first surface molecule, positioned parallel with the first-surface molecule, is configured to maintain bonds between the first portion and the first surface up to one or more pre-determined three scenarios, such as pre-determined shear, pull, and peel forces being exerted on the first surface. The second portion can function similarly with respect to the second surface.
