Abstract: Systems and methods are provided for fixturing hairpins for joining by welding. A fixture system includes an outer structural ring fixed relative to an inner structural ring and mates with the component around its hairpin type conductor ends. Dielectric rings are disposed between conductor pairs. Clamp rings are disposed on opposite sides of the dielectric rings. One clamp ring and one dielectric ring define an opening receiving one conductor pair. Another clamp ring and another dielectric ring define another receiving another conductor pair. The clamp rings are movable toward one another to align and crowd the conductor pairs between the clamp rings and the dielectric rings prior to welding.

Abstract: An electrical connector verification system including a microphone for detecting a first sound generated by an engagement of a locking mechanism of an electrical connector and for generating a first signal representative of the first sound, a processor for generating a control signal in response to the first signal matching a second signal representative of a second sound generated in response to a correct engagement of the locking mechanism of the electrical connector above a certainty threshold, and a user interface for displaying an indication of a correctly seated electrical connector in response to the control signal.

Abstract: A system for welding together tips of different wires arranged about a motor stator. A scanner control module is configured to operate a three-dimensional scanner to scan the tips of the different wires and measure alignment of the tips in X, Y, and Z directions of a coordinate plane. A system control module is configured to compare the measured alignment of the tips to a predetermined alignment range, and configured to identify a weld schedule for each of the tips that fall within the predetermined alignment range. A laser welder control module is configured to operate a laser welder to weld together only the tips aligned within the predetermined alignment range in accordance with the weld schedule identified by the system control module.

Abstract: An emblem installation system for installing emblems on a work piece includes an end effector for a robotic arm. The end effector has a base and multiple vacuum gripper modules repositionable along the base in different configurations. The vacuum gripper modules are configured to simultaneously grip multiple emblems and individually release the emblems. An emblem installation method includes applying a force within a first range of forces to the multiple emblems individually and in succession via vacuum gripper modules of an end effector on a robotic arm, with the emblems disposed at a first location, applying a vacuum to the vacuum gripper modules to grip the emblems with the vacuum gripper modules, and moving the robotic arm from the first location to a second location adjacent a workpiece with the emblems gripped by the vacuum gripper modules.

Abstract: An end-effector for installation of an emblem assembly is provided. The end-effector includes a support frame, a first splitter, and a second splitter. The first splitter and the second splitter are connected to the support frame. The pneumatically actuated grippers include: a first gripper connected to the first splitter and configured to grab at least a portion of the emblem assembly; and a second gripper connected to the second splitter and configured to peel off one or more layers of the emblem assembly. The roller is connected to the support frame and configured to wet out an adhesive layer of the emblem assembly.
