Abstract
A flattening device includes a main roller and a plurality of sleeves. The plurality of sleeves are sleeved on the main roller at intervals in an axial direction of the main roller. At least one of the sleeves is detachably connected to the main roller, so that positions of the sleeves in the axial direction of the main roller are adjustable, and the sleeves are in contact with the electrode plate to flatten the electrode plate when the electrode plate passes through the sleeves.
