Abstract

The present invention provides an electric core end face kneading flattening device, which comprises a frame, an electric core clamping device and a kneading flattening device, the electric core clamping device and the kneading flattening device are correspondingly arranged, the electrical core clamping device is arranged on the frame through a rotating device, the kneading flattening device is installed slidably on the frame, and a sliding seat can move front and back relatively to the kneading flattening device. The electric core clamping device and the kneading flattening device are arranged on the frame, the electric core clamping device is used for fixing and clamping an electric core to match with the kneading flattening device for kneading flattening shaping of end faces of the electric core, meanwhile the electrical core clamping device is arranged on the frame through the rotating device, the rotating device drives the electric core clamping device to rotate so as to realize the automatic reversing of the electric core, the processing efficiency is improved, labor intensity is reduced, clamping error caused by secondary clamping can be avoided, wherein the clamping error can lead to differences in shaping effect of the two end faces of the electric core, and can affect the processing quality.

Description

technical field [0001] The invention relates to the technical field of battery preparation, and more specifically, to a device for smoothing the end surface of a battery cell. Background technique [0002] The existing large-capacity cylindrical lithium-ion batteries mostly use full-tab positive and negative electrodes. At present, the existing battery generally adopts the positive and negative electrodes of the full tab type, that is, when the positive electrode slurry is coated on the positive electrode current collector (usually aluminum foil), a part of the area not coated with slurry is reserved on the edge of one end (positive aurora foil area). ), when coating the negative electrode slurry on the negative electrode current collector (usually copper foil), reserve a part of the area (negative aurora foil area) where the slurry is not coated on the edge of one end. After the positive electrode sheet, the negative electrode sheet and the diaphragm are wound to form the ...
