Dislocation winding method

Abstract

The invention relates to the field of storage battery processing, and specifically discloses a dislocation winding method. The dislocation winding method comprises the following steps that step (1) agrid is slit by a slitting knife, and the grid is enabled to form a plurality of grid bars; step (2), the grid bars are wound by a winding roller to form a grid roll, the grid bars are required to betwisted during winding, the twist angle of the grid bars is 30-50 degrees, and the winding speed of each grid bar is the same; step (3), when the diameter of the grid roll reaches 30-50 cm, winding ofthe grid is stopped; and step (4), the grid is cut off, the grid roll is bound, and the grid roll is removed. When the winding roll is wound around the grid, the grid is twisted at a certain angle, so after the slit grid is wound on the winding roller, the horizontal distance between two ends of the formed grid roll is smaller than the actual width of the grid, and installation spaces are left attwo ends of the winding roller.

Description

technical field [0001] The invention relates to the field of storage battery processing, in particular to a dislocation winding method. Background technique [0002] With the development of automobile lightweight process, the application of carbon fiber composite materials in automobiles, especially new energy vehicles, is also increasing. Among the structural parts of various parts of the car, the battery box using carbon fiber composite materials as raw materials is more popular. The design and manufacture of the battery box made of carbon fiber composite materials is also relatively complicated. The structure, weight, high temperature resistance, chemical properties, and mechanical properties of the battery box are all factors to be considered during manufacturing. [0003] The battery made of carbon fiber composite material is called a carbon fiber battery. The battery box is equipped with a grid. By filling the battery box with electrolyte, the electrolyte will be adso...

Problems solved by technology

In order to improve the production efficiency of the braiding machine, the grid produced by the braiding machine usually has a wider width. It will be inconvenient to load and transport the grid

Therefore, considering the weaving efficiency of the grid and the convenience of transportation, the width of the weaving machine is usually controlled within an appropriate range to control the width of the produced grid, which greatly limits the production efficiency of the weaving machine

[0005]At present, in order to improve production efficiency, our company has further increased the width of the weaving machine to obtain a wider grid; but in order to facilitate the loading and For transportation, before winding the grid, the grid cutting mechanism will be used to cut the grid and then roll it; but because there is no gap between the grids after cutting, the current The winding device cannot wind the slit grids on different winding rollers; if each grid is to be wound on different winding rollers, since the two ends of the winding rollers need to be reserved for installation Space, in order to prevent the mutual interference of adjacent winding rollers, it is necessary to reset the arrangement of winding rollers
