The granted patent (Publication Number: US11929464B2) discloses a conveying roller designed for efficiently conveying a cell pole piece, which consists of a main body and pole tabs. The conveying roller features a central axis, two end faces, a transmission portion, and an avoidance position. The transmission portion, rotatable around the central axis, applies a transmission friction force to the cell pole piece's bearing area, facilitating movement. The avoidance position, a space on the roller, suspends both the cell pole piece and the transmission portion, effectively avoiding contact with the transition area and pole tabs.

Furthermore, the conveying roller can include a mandrel, with the transmission portion configured as a rotating cylinder. The difference in radius between the rotating cylinder and the mandrel, along with a rounded transition structure, enhances the conveying process. The patent also covers a winder incorporating this conveying roller, emphasizing its application in efficiently moving cell pole pieces. Additionally, a method for conveying a cell pole piece using the described conveying roller is detailed, highlighting the role of the transmission portion in driving the movement of the cell pole piece while ensuring the avoidance position prevents interference with critical components like the transition area and pole tabs.
