Description

Technical Field

[0001] The utility model relates to the field of batteries, in particular to a novel cam turret type battery cell short-circuit tester. Background Art

[0002] As the energy crisis and environmental problems become increasingly severe, with the country's strong support for the new energy industry, key technologies for power batteries have gradually matured, and various types of power batteries have been widely used in electric cars, electric motorcycles, electric bicycles, solar energy, mobile communication terminal products and energy storage products.

[0003] Short-circuit testing is an essential process in battery cell manufacturing. Traditional battery cell short-circuit testing machines have a complex and large overall structure. The clamping device has a complex structure, occupies a large space, and has difficulty controlling pressure accuracy, which can easily cause tab deformation. Installation and maintenance are difficult, making the short-circuit test control process complex and costly. On a linear production line, the test stations are fixed, and the battery cells need to stop moving during testing, seriously affecting the efficiency of automated battery production and assembly. Without a tab alignment device, the tabs are incorrectly positioned when the battery cells arrive, resulting in empty tabs during testing. This can cause unqualified batteries to be misjudged and flow into the next process, hindering mass production. Therefore, a new cam turret-type battery cell short-circuit testing machine is proposed. Utility Model Content
