Abstract
A cylindrical cell flattening method and apparatus are disclosed, which relate to the technical field of cell manufacturing. The cylindrical cell flattening method includes the steps of: loading a battery core onto a base; compressing an outer peripheral surface of the battery core and fixing the battery core; and applying a force to the tabs of the battery core in an axial direction thereof so as to flatten the tabs. The cylindrical cell flattening method and apparatus provided by the present application enables flattening of the tabs of the battery core without colliding with an end surface of the battery core, thus reducing the reject rate during processing.
Claims12
A cylindrical cell flattening method, comprising the following steps:
- S0:
- loading a battery core onto a base;
- S1:
- compressing an outer peripheral surface of the battery core and fixing the battery core;
- and
- S2:
- applying a force to a tab of the battery core in an axial direction thereof so as to flatten the tab.
A cylindrical cell flattening apparatus, comprising a base, a fixing device and a flattening device, wherein
- the base is configured to carry a battery core;
- the fixing device comprises a driving mechanism and a fixing piece, wherein the fixing piece is mounted at an output end of the driving mechanism, and the driving mechanism is configured to drive the fixing piece to move toward the base to fix the battery core onto the base;
- and
- the flattening device comprises a pair of flattening mechanisms respectively arranged on two sides of the base, each flattening mechanism comprising a first driving member and a flattening seat, wherein the flattening seat is mounted on the first driving member, and the first driving member is configured to drive the flattening seat to press the tab of the battery core.
