Abstract: A method for optimizing a schedule for impulse welding including generating a weld lobe using a preexisting welding schedule, the schedule prescribing a current, a weld time, and a pressure; identifying an operating window on the weld lobe; analyzing the operating window, the analysis including determining a maximum time range of the operating window, and determining a maximum current range of the operating window; until (i) the determined maximum time range of the operating window is greater than a predetermined percentage of the prescribed weld time of the schedule and (ii) the determined maximum current range is greater than the prescribed current of the schedule, creating additional weld lobes by varying the pressure and repeating the identifying an operating window and the analyzing the operating window steps; and selecting, within the operating window satisfying conditions (i) and (ii), a second schedule including a second weld time, a second current, and a second pressure.

Abstract: A weather strip installation device for mechanically installing weather strip along the opening of a vehicle door is disclosed. The device includes a frame outlining said opening, and a plurality of contact pads enclosing the frame. A selectively movable unit is disposed between the frame and the contact pads, wherein the selectively movable unit is operable to push each of the contact pads outwardly from the frame. In the first preferred embodiment the movable unit is a plurality of expandable bladders disposed between the contact pads and the peripheral edge of the frame. In the second preferred embodiment, the movable unit is an extensible arm rotatably attached to the frame. The extensible arm includes a roller disposed between the frame and contact pads that presses against the contact pads thereby installing the weather strip along the opening of the door as the extensible arm rotates about the frame.

Abstract: A quality control system and method for monitoring an assembly operation is provided. The method can include: (1) providing an assembly line having a plurality of machines being assembled thereon; (2) providing a tool for performing an assembly operation; (3) performing a plurality of the assembly operations with the tool; (4) measuring a measurable parameter indicative of the performance of the tool for at least a subset of the plurality of assembly operations; (5) storing the measured values in an electronic format with a data collection device; (6) analyzing the measured values; and (7) providing a signal based on the analysis with the signal indicative of at least satisfactory or unsatisfactory performance of the tool. In some instances, the data collection device can provide for storing additional information and/or data with any particular stored measured value.
