Rolling folding mechanism

Abstract

The invention discloses a rolling folding mechanism, which comprises a rolling folding base and a rolling folding bracket arranged on the rolling folding base, wherein the other rolling folding bracket is arranged in a mirror image of the rolling folding bracket; rolling folding pallets are arranged on the opposite side surfaces of the two rolling folding brackets; a rolling folding channel is formed between the two rolling folding pallets; each rolling folding bracket is provided with a horizontal first roller group and a vertical second roller group along the direction of the corresponding rolling folding pallet; and each first roller group and second roller group are arranged in a plane in which the corresponding rolling folding pallet is located in a semisubmersible manner. A battery plastic packaging film can be quickly folded from two horizontal sides to two vertical sides, so that the rolling folding mechanism is good in bending effect, consistent in specification and high in quality.

Description

technical field [0001] The invention relates to a rolling mechanism, in particular to a rolling mechanism of a battery plastic sealing film. Background technique [0002] Batteries are the power source of many electronic and electrical equipment. The rapid development of transportation, communication and electronic information technology, and the in-depth popularization of electric vehicles, mobile phones and notebook computers in people's lives have greatly promoted the progress of battery technology, so new battery products emerge in endlessly. [0003] Among them, lithium-ion batteries have attracted more and more attention from all walks of life, such as the electric vehicle industry, because of their advantages such as large capacity, long cycle life, and high cost performance. Lithium-ion batteries are generally composed of positive electrodes, negative electrodes, separators, electrolytes, and the like. The pole pieces are separated by a diaphragm to make a battery ...

AI Technical Summary

Problems solved by technology

This is not only inefficient, but also due to direct contact with the battery during manual operation, the safety of the operation cannot be guaranteed, and it is easy to increase the defective rate of the battery; in addition, manual positioning, trimming or folding can also easily lead to inconsistent sides of the battery. Slow down the production speed of finished battery products and reduce the quality of battery production

[0005] At present, in the process of folding the battery, it is usually bent manually, and there is a large difference in the bending length and angle, which makes the edge of the battery uneven when it is pressed, which affects the use.
