Rolling and folding reshaping mechanism

Abstract

The invention discloses a rolling and folding reshaping mechanism. The rolling and folding reshaping mechanism comprises a rolling and folding base, rolling and folding supports, reshaping supports and reshaping carrying tables, wherein the rolling and folding supports, the reshaping supports and the reshaping carrying tables are arranged on the rolling and folding base. One rolling and folding support and the other rolling and folding support are arranged in a mirrored manner. The opposite side faces of the two rolling and folding supports are each provided with a rolling and folding carryingtable. A rolling and folding channel is formed between the two rolling and folding carrying tables. Each rolling and folding support is provided with a horizontal first rolling wheel set and a vertical second rolling wheel set in the direction of the corresponding rolling and folding carrying table. Each first rolling wheel set and the corresponding second rolling wheel set are arranged in a plane where the corresponding rolling and folding carrying table is located in a semi-immersed manner. The reshaping supports are symmetrically arranged at the two sides of the extension line of the rolling and folding channel. Each reshaping support is provided with a reshaping driving source, and a reshaping heating block is arranged at the free end of each reshaping support. The reshaping carryingtables are arranged between the two reshaping supports. By means of the rolling and folding reshaping mechanism, reshaping can be conducted on side edges of batteries automatically; the reshaping specification is uniform; and the batteries cannot be damaged.

Description

technical field [0001] The invention relates to a rolling and shaping mechanism, in particular to a rolling and shaping mechanism for 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 dia...

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] After the battery is folded, the plastic film may gradually loosen over time, affecting the size of the battery. It needs to be further heated and shaped, and manual shaping often results in inconsistent flatness or tightness of the sides, and even damages the battery.
