摘要： One or more aspects of the present disclosure are directed to a synchronized actuation system for holding samples (e.g., battery cells) in place such that ultrasonic sensors can make physical contacts with the samples to transmit and receive acoustic signals across the samples for purposes of making ultrasound measurements of the battery sample. The movement of sensors on both sides of a sample can be synchronized (as opposed to being handled via independent actuators) to improve signal repeatability.

摘要： One or more aspects of the present disclosure are directed to fixturing mechanisms for placement of battery cells inside an ultrasonic testing system. The disclosed fixturing mechanisms enable accurate and predictable loading, placement, and unloading of battery cells inside ultrasonic testing systems allowing all faces of battery cells of different types (e.g., pouch cells, prismatic cells, cylindrical cells, etc.) to have sufficient exposure to transmission and reception of acoustic signals. This fixturing mechanism furthers the goal of providing a robustly designed ultrasonic test system and producing accurate inspection results for batteries.
