Problems solved by technology

During the winding process, the length of the diaphragm used in the winding process of each cell is certain. Some traditional winding machines need to manually cut the diaphragm into sections and manually put it into the winding machine. The production efficiency is very low; there are also some winding machines that use material rolls to discharge the diaphragm, because the battery core is rotating during the winding process, and the diaphragm is flexible, so the diaphragm will shake, making the machine unable to cut the diaphragm accurately. As a result, the length of the diaphragm wound by each cell is different, which affects the consistency of the cell, reduces the quality of the cell, and affects the benefits of the enterprise

Abstract

The invention discloses a diaphragm cutting mechanism of a lithium battery winding machine. The diaphragm cutting mechanism comprises a bracket, a slide seat and a fixing seat. The bracket, the slideseat and the fixing seat are sequentially connected with one another, a support table is arranged on a side of the fixing seat, a cutter for cutting off diaphragms is arranged on the support table, aone-way wheel and a pushing strip are arranged on the upper side and the lower side of the cutter, and a movable seat which is connected with the one-way wheel is arranged on the upper side of the support table, and is provided with a gas blowing seat which is arranged above the one-way wheel; the fixing seat is provided with a movement assembly for driving the movable seat to move on the front side and the rear side of the cutter back and forth; a driving assembly for driving the slide seat to horizontally move is arranged on the bracket. The diaphragm cutting mechanism has the advantages that the diaphragm cutting mechanism is reasonable in structure; the diaphragms on the upper side and the lower side of the cutter can be stably compressed by the one-way wheel and the pushing strip at first and then can be stably and accurately cut off by sawteeth of the cutter, accordingly, the lengths of the diaphragms wound on battery cells are consistent with one another, the consistency and thequality of the battery cells can be improved, and benefits of enterprises can be increased.

Description

technical field [0001] The invention relates to the technical field of battery production equipment, in particular to a diaphragm cutting mechanism of a lithium battery winding machine. Background technique [0002] In the current lithium battery equipment, batteries composed of batteries formed by winding are called winding batteries, and winding batteries are also called batteries. The battery core in the form of winding can make the performance of the lithium battery stable and the manufacturing efficiency high. The winding machine winds the battery positive electrode, negative electrode, and separator paper in a specific layer sequence to form a battery cell. During the winding process, the length of the diaphragm used in the winding process of each cell is certain. Some traditional winding machines need to manually cut the diaphragm into sections and manually put it into the winding machine. The production efficiency is very low; there are also some winding machines t...
