The invention relates to a power battery pole piece winding feeding trolley. The power battery pole piece winding feeding trolley comprises a trolley body support, a supporting plate and an arc plate,wherein the supporting plate is arranged on the trolley body support and can be moved up and down, the arc plate is arranged on the supporting plate and can be moved forwards and backwards, the arc plate is used for containing a battery pole piece, and a pressing device for limiting forward and backward displacement of the arc plate is arranged between the supporting plate and the arc plate. As is seen from the technical scheme, the arc plate of the power battery pole piece winding feeding trolley can realize the displacement of up-and-down and forward-and-backward positions, and a winding drum hole of the power battery pole piece and an air expansion shaft of a winder are accurately positioned; and meanwhile, the arc plate can be locked through the pressing device, and the problem of pole piece falling off caused by forward and backward displacement of the arc plate in the moving process of the feeding trolley is solved. The power battery pole piece winding feeding trolley can achieve precise localization and quick feeding and is low in operative difficulty and high in production efficiency.
