Abstract
The present disclosure relates to a conveying roller for conveying a cell pole piece, the cell pole piece comprising a main body and pole tabs, the main body comprising a bearing area and a transition area, each of the pole tabs comprising a root portion connected to the transition area, a middle section and a top portion, and the conveying roller comprising: a central axis, a first end face and a second end face disposed opposite to each other along the central axis, a transmission portion and an avoidance position provided between the first end face and the second end face, wherein the transmission portion is rotatable around the central axis, the bearing area is contactable with the transmission portion, so that the transmission portion applies a transmission friction force to the cell pole piece, and the avoidance position is capable of avoiding the transition area and the pole tabs.
