Abstract

The invention discloses electrode plate production equipment. The electrode plate production equipment comprises a winding machine; the winding machine comprises a core rod used for winding a positiveelectrode plate, a diaphragm 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 and welding manner; the driving mechanism is mounted on the mounting bracket; the driving mechanism comprises a sliding block, a threaded rod, a motor for driving the threaded rod to rotate, and two guiding rods parallel to the threaded rod and arranged on the two sides of the threaded rod respectively; the sliding block is in threaded connection with the threaded rod, and in gliding connection with the two guiding rods; and the welding part is mounted on the sliding block. By virtue of the electrode plate production equipment, the cell winding process speed is improved and battery production efficiency is improved; and in addition, 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 throughthe heating and welding manner, so that the diaphragm can be firmly and accurately 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 pole piece production equipment. 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...
