Folding mechanism

Abstract

The invention discloses a folding mechanism, which comprises a folding base, a folding bracket and a folding pallet, wherein the folding bracket and the folding pallet are arranged on the folding base; the folding bracket is provided with a corner pressing plate, an upper folding knife and a lower folding knife in a sliding manner; the corner pressing plate, the upper folding knife and the lower folding knife all are connected with a drive source; a pressing knife is arranged on the lower folding knife in a manner of protruding upwards, and is located at the lower part of the corner pressing plate; the corner pressing plate is overlapped with the inner side surface of the pressing knife; and the outer side surface of the upper folding knife is overlapped with the inner side surface of thepressing knife. The folding mechanism is capable of automatically folding a plastic packaging film of a battery, and is consistent in folding specification and high in folding efficiency.

Description

technical field [0001] The invention relates to a folding mechanism, in particular to a battery folding mechanism. 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 core package, and then the...

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 battery folding, it is usually bent manually, and there are large differences in the bending length and angle, which affects the specifications of the battery.
