摘要： A number of variations may involve a method that may include providing a non-conductive layer. A conductive layer may be provided overlying the non-conductive layer with the conductive layer to form a sensor device. An opposition to electrical current through the conductive layer may be monitored. The location of a status of the non-conductive layer or of the conductive layer may be determined through a change in the opposition.

摘要： A mechanically conformable micro-heat exchanger for use in managing temperature of a subject component. The exchanger includes a flexible fluid tube. In various embodiments, the tube is connected to a flexible substrate, such as by a flexible polymer. The exchanger can be changed manually from an initial shape to a first shape to conform to a shape of the subject component. The flexible fluid tube is configured to channel heat-transfer fluid through a heat-transfer tube section of the tube. The heat-transfer fluid is configured to cool or heat the subject component when, in operation of the mechanically conformable micro-heat exchanger, the heat-transfer fluid is channeled through the heat-transfer tube section.

摘要： A vibration welding system includes vibration welding equipment having a welding horn and anvil, a host device, a check station, and a robot. The robot moves the horn and anvil via an arm to the check station. Sensors, e.g., temperature sensors, are positioned with respect to the welding equipment. Additional sensors are positioned with respect to the check station, including a pressure-sensitive array. The host device, which monitors a condition of the welding equipment, measures signals via the sensors positioned with respect to the welding equipment when the horn is actively forming a weld. The robot moves the horn and anvil to the check station, activates the check station sensors at the check station, and determines a condition of the welding equipment by processing the received signals. Acoustic, force, temperature, displacement, amplitude, and/or attitude/gyroscopic sensors may be used.

摘要： A method of analyzing the quality of a battery cell includes performing a high-throughput quality check on the battery cell with a quality control system, assessing a quality score to the battery cell, with quality score identifying the battery cell as low-quality or high-quality, and performing a comprehensive quality check on the battery cell if identified as low-quality. The method further includes assessing an enhanced quality score to the battery cell superseding the quality score of the quality control system identifying the battery cell as confirmed low-quality or confirmed high-quality and providing revised production instructions for manufacturing successive battery cells if confirmed low-quality.

摘要： A method and a test fixture for evaluating a battery cell are described, wherein the battery cell is composed of a cell body having a plurality of electrode foils that are joined to both a positive terminal and a negative terminal at weld junctions. The method includes retaining the cell body of the battery cell in a first clamping device and gripping one of the positive and negative terminals in a terminal gripper. A dynamic stress end effector coupled to the terminal gripper is employed to apply a vibrational excitation load to the one of the positive and negative terminals. Impedance between the positive terminal and the negative terminal is monitored via a controller, and integrity of the weld junction of the one of the positive and negative terminals is evaluated based upon the impedance.

摘要： A method includes receiving, during a vibration welding process, a set of sensory signals from a collection of sensors positioned with respect to a work piece during formation of a weld on or within the work piece. The method also includes receiving control signals from a welding controller during the process, with the control signals causing the welding horn to vibrate at a calibrated frequency, and processing the received sensory and control signals using a host machine. Additionally, the method includes displaying a predicted weld quality status on a surface of the work piece using a status projector. The method may include identifying and display a quality status of a suspect weld. The laser projector may project a laser beam directly onto or immediately adjacent to the suspect welds, e.g., as a red, green, blue laser or a gas laser having a switched color filter.

摘要： A system includes a host machine and a status projector. The host machine is in electrical communication with a collection of sensors and with a welding controller that generates control signals for controlling the welding horn. The host machine is configured to execute a method to thereby process the sensory and control signals, as well as predict a quality status of a weld that is formed using the welding horn, including identifying any suspect welds. The host machine then activates the status projector to illuminate the suspect welds. This may occur directly on the welds using a laser projector, or on a surface of the work piece in proximity to the welds. The system and method may be used in the ultrasonic welding of battery tabs of a multi-cell battery pack in a particular embodiment. The welding horn and welding controller may also be part of the system.
