TAB CUTTING MECHANISM AND BATTERY ASSEMBLING SYSTEM

A tab cutting mechanism includes a supporting structure, a cutting blade assembly, an electrode assembly positioning assembly, and a first driving assembly. The cutting blade assembly includes a first component and a second component. The first component is mounted on the supporting structure. The electrode assembly positioning assembly is mounted on the supporting structure and is configured to support and position a main body part of an electrode assembly. The first component is configured to support a tab portion of the electrode assembly. The first driving assembly is mounted on the supporting structure, is connected to the second component, and is configured to drive the second component to move, to cause the second component to cooperate with the first component to cut the tab portion.
