Abstract: A system for inspecting a stator stack includes a rotary table, an imaging device configured to take a plurality of images of a portion of the stator stack including a stator slot, an illuminator configured to apply illumination through the stator slot, and an alignment and monitoring system configured to monitor and orient the stator slot relative to the imaging axis. The alignment and monitoring system includes a tilting system configured to move the stator slot between a plurality of orientations relative to an imaging axis, the imaging device configured to take a respective image at each of the plurality of orientations, a controller configured to control the tilting system based on one or more measurements of each image, and a processor configured to analyze each image and select an orientation of the stator slot as an optimal orientation for inspection of the stator slot.

Abstract: A system for evaluating a battery cell includes an imaging device configured to take an image of at least part of the battery cell, and a processor. The processor is configured to perform: determining a region of interest in the acquired image, reducing a sharpness of the acquired image to generate a reference image, comparing the acquired image and the reference image, and identifying a discontinuity of the battery cell based on a difference between the acquired image and the reference image.

Abstract: A calibration system for multiple image sensors includes a manufacturing apparatus, a first imaging sensor, a second imaging sensor positioned at a different location than the first imaging sensor and configured to capture at least one different wavelength than the first imaging sensor, a calibration artifact, and an imaging calibration module. The imaging calibration module is configured to obtain first and second images of the calibration artifact via the first and second imaging sensors, determine first and second pixel mappings between the first and second images and a common coordinate system, according to a location of the calibration artifact in the first and second images, convert an image of a manufacturing object captured by the first imaging sensor to the common coordinate system, and convert an image of the manufacturing object captured by the second imaging sensor to the common coordinate system.

Abstract: A method of inspecting a stator stack includes disposing the stator stack on a support surface of an inspection system, and performing a depth measurement of a stator slot. The depth measurement includes rotating the stator slot along a first direction to a plurality of first orientations, taking a first image at each of the first orientations, and measuring a depth based on at least one of the first images. The method includes performing a width measurement of the stator slot, which includes rotating the stator slot along a second direction to a plurality of second orientations, taking a second image at each of the second orientations, and measuring a width based on at least one of the second images. The method further includes inspecting edges of the stator slot in the at least one of the first images to detect a potential deviation.

Abstract: A quality control system analyzes the quality of a battery cell, with the battery cell defining a gas pouch configured to expand from a deflated configuration to an inflated configuration when filled with a gas formed during a cell formation process. The system comprises a computational system comprising a processor and a memory and a measurement instrument in electronic communication with the computational system. The measurement instrument is arranged to measure a distance defined by the gas pouch and transmit a signal to the computational system corresponding to the distance. The computational system is arranged to analyze the distance with the processor and determine a volumetric measurement of the gas within the gas pouch and compare the volumetric measurement to a threshold in the memory to assess a quality score for the battery cell. A corresponding method analyzes the quality of the battery cell with the quality control system.
