ELECTRODE PLATE LAMINATING DEVICE, BARE CELL WINDING APPARATUS, AND BARE CELL WINDING METHOD

Disclosed in the present application are an electrode plate laminating apparatus (100), a bare cell winding device, and a bare cell winding method. The electrode plate laminating apparatus (100) comprises: a first laminating roller assembly (20), which comprises a first laminating roller (21) and a second laminating roller (22), the first laminating roller (21) and the second laminating roller (22) being arranged directly opposite each other, and the first laminating roller (21) and the second laminating roller (22) being configured to sequentially stack and laminate a first separator (11), a first electrode plate (12) and a second separator (13) together, and a side separator laminating assembly (30), which is configured to laminate the part of the first separator (11) extending beyond a side edge of the first electrode plate (12) with the part of the second separator (13) extending beyond the side edge of the first electrode plate (12). By applying the technical solution provided by the embodiments of the present application, the problem of the first electrode plate and a second electrode plate overlapping each other due to the fact that the separators are prone to being folded in the winding process during preparation of the bare cell by the first separator, the first electrode plate, the second separator and the second electrode plate is solved.
