AI Technical Summary
Existing technologies cannot quickly and accurately detect the bottom corner packaging width of pouch batteries, resulting in low detection efficiency and an inability to meet the real-time feedback requirements of the production line. Furthermore, they are limited in versatility and cost.
A caliper-type measuring fixture consisting of a main scale assembly and a secondary scale assembly was designed. It achieves rapid and accurate measurement of the bottom corner encapsulation width of the battery by using sliding fit and matching rounded corners for precise positioning, combined with a visual qualification window for simultaneous double-sided reading.
It enables rapid and accurate testing of different battery models, reduces testing costs, improves testing efficiency and real-time feedback capabilities, and is suitable for widespread use on production lines.
