Abstract

The invention discloses an electrode plate winding apparatus. The winding apparatus comprises a winding machine; the winding machine comprises a core rod used for winding a positive electrode plate, adiaphragm and a negative electrode plate, and also comprises a mounting bracket, a driving mechanism, and a welding part for gluing the diaphragm on the surface of the core rod through a heating andwelding manner; the core rod is horizontally arranged; and the welding part is positioned below the core rod. By virtue of the electrode plate winding apparatus, the cell winding process speed is improved and battery production efficiency is improved; and in addition, compared with a way of gluing the diaphragm and the core rod through a double sides adhesive tape, the diaphragm and the core rod can be fused through one or two kinds of materials and can be directly connected into an integrated body through the heating and welding manner in the invention, so that the diaphragm can be firmly andaccurately glued on the core rod, the cell quality is ensured effectively, and the percent of pass is improved.

Description

technical field [0001] The invention relates to battery processing equipment, in particular to a pole piece winding device. Background technique [0002] In the production process of the existing large cylindrical lithium-ion battery and other batteries, when the battery core is formed by the pole piece winding process, it is first necessary to manually use double-sided adhesive to stick the diaphragm and the battery mandrel together, and then put the positive and negative pole pieces The pole piece winding is started, and the winding of each cell is processed one by one in this way. [0003] However, this method of artificially bonding the separator and mandrel reduces the process speed of cell winding on the one hand, resulting in low battery production efficiency; Problems such as position offset will lead to poor quality or low pass rate of batteries to a certain extent. Contents of the invention [0004] The present invention aims to solve the technical problems men...
