A ribbon carrier assembly, a welding device, and a welding method for preprocessing between a battery sheet and a ribbon are disclosed. The carrier assembly includes a carrier seat; a carrier body, rotatably connected to the carrier seat; and a driving assembly, connected to the carrier body and configured to control the rotation of the carrier body. At least one operation surface is arranged on the carrier body and is arranged as a curved surface. Adsorption holes are arranged on the operation surface. The battery sheet is adsorbed and fixed to the operation surface by applying a negative pressure to the adsorption holes. Through tins, dry joints between the battery sheet and the ribbon can be reduced during welding of the ribbon and the battery sheet. The battery sheet is bent on the curved surface to avoid warping or cracking of the battery sheet caused by excessive heating.
