Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery tab detection equipment, in particular to a lithium battery tab leveling and size detection device. Background Art

[0002] During the production of lithium batteries, the tabs need to be flattened and their sizes measured. Currently, the error rate when measuring the tabs is high, or the tabs cannot be measured.

[0003] Since the tabs are soft, wrinkles are easily generated, which is similar to boundary features, interfering with the results and affecting the measurement accuracy. The current general leveling structure is a pressure rod, which cannot completely reduce the wrinkles. In addition, due to the floating gap between the battery cells, the position of the tab pressure rod indentation (not pressing on the tab & pressing on the root of the tab) affects the measurement.
