Pole core assembling mechanism for automatic production of lithium battery

Abstract

The invention discloses a pole core assembling mechanism for automatic production of a lithium battery, and relates to the technical field of lithium battery production. The conveying belt is used for conveying and feeding a container filled with battery fluid; and the gluing mechanism is arranged at the right end of the assembly table. The pole core assembling mechanism also comprises an assembling mechanism which is connected to the top of the assembling table; the lifting cutter is arranged on the right side of the assembling mechanism and fixedly connected with the assembling table. According to the pole core assembling mechanism for the automatic production of the lithium battery, the positive pole film, the diaphragm and the negative pole film are glued and are subjected to side edge limiting in the overlapping process, so the three films can be overlapped, and dislocation at the edges is avoided, so there is no need of cutting for the improvement of the work efficiency; pressure is applied from top to bottom in the process of winding the positive electrode film, the diaphragm and the negative electrode film on the container, so the positive electrode film, the diaphragm and the negative electrode film are firmly adhered to the surface of the container, and meanwhile, bubbles can be prevented from being generated through pressure application.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a pole core assembly mechanism for automatic production of lithium batteries. Background technique [0002] The core of the lithium battery is also called the battery core. It is composed of a positive electrode film, a separator, a negative electrode film, and a container filled with electrolyte. container surface. [0003] When the existing lithium battery cells are assembled, the positive electrode film, separator, and negative electrode film are prone to misalignment during the overlapping process, resulting in the need for edge trimming after overlapping, resulting in waste of materials and prolongation of the processing process. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the present invention provides a pole core assembly mechanism for automatic production of lithium batteries, which solves the problem that the posi...
