Abstract: 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.

Abstract: A welding assembly includes a sonotrode, cleaning station, and controller. The controller periodically commands clamping of the sonotrode onto the cleaning block, and a transmission of ultrasonic energy into the cleaning block for a calibrated duration sufficient for removing residual amounts of metal from welding pads of the sonotrode. The cleaning block may include an aluminum bar coated with a polymeric material, e.g., porous polyethylene silica or alumina composite. A thin sacrificial layer of an anti-adhesion material, e.g., colloidal silica, may be periodically applied to the welding pads, particularly after a transition from welding a first metal to welding a second metal. The sacrificial layer may be applied via a sponge, a saturated surface, or spraying.
Abstract translation: 焊接组件包括超声波发生器，清洁站和控制器。 控制器周期性地指示超声波发生器夹在清洁块上，并将超声波能量传输到清洁块中，该校准持续时间足以从超声波焊接焊盘去除剩余的金属量。 清洁块可以包括涂覆有聚合材料的铝棒，例如多孔聚乙烯二氧化硅或氧化铝复合材料。 特别是在从第一金属焊接到焊接第二金属的过渡之后，可以周期性地对焊接垫施加抗粘附材料（例如胶体二氧化硅）的薄牺牲层。 牺牲层可以经由海绵，饱和表面或喷涂施加。

Abstract: A method and fixture for welding a battery foil-tab assembly is disclosed. The fixture includes a first clamp member having a first clamping surface defining an opening extending into the first clamp member and a second clamp member having a protrusion surrounding a weld slot. The opening of the first clamp member is configured to receive a portion of the protrusion with the battery foil-tab assembly disposed therebetween. The second clamp member is moveable toward the first clamp member to align the weld slot of the second clamp member with the opening of the first clamp member, thereby causing the protrusion to cooperate with the opening of the first clamp to deflect a portion of the battery foil-tab assembly out of a plane parallel with the battery foil-tab assembly. A laser beam is directed at the out of plane portion to laser weld the battery foil-tab assembly.

Abstract: A computer software product adapted for use in a weld inspection system is executed by a processor and is stored in an electronic storage medium of the weld inspection system adapted to facilitate the inspection of a weld of a work product. The computer software product includes a first module and a combination module. The first module is configured to transform first and second raw thermal images, associated with respective first and second heat pulses of at least a portion of the work product having the weld, into respective first and second binary images. The combination module is configured to transform the first and second binary images into a combined binary image for the reduction of noise.
