Abstract

The invention provides an unreeling device and a laminating machine and relates to the technical field of lithium battery manufacturing equipment. The unreeling device comprises an unreeling mechanismfor releasing a diaphragm in a material coil, a tension control mechanism for adjusting the tension of the transported diaphragm, a caching mechanism for caching the transported diaphragm, and a plurality of via rollers for guiding, supporting and tensioning the transported diaphragm. The diaphragm released by the unreeling mechanism enters a laminating mechanism through the via rollers, the tension control mechanism and the caching mechanism and the laminating mechanism drives the diaphragm to move in a reciprocating manner to laminate in a Z shape. The laminating machine comprises the unreeling device. The invention aims to provide the unreeling device and the laminating machine to alleviate the problem that the laminating efficiency is affected when the tension of the diaphragm is controlled improperly in the prior art.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing equipment, in particular to an unwinding device and a stacking machine. Background technique [0002] Lithium battery lamination technology is a technology that uses separators to separate the positive and negative plates, and stack them in turn to form battery cells. There are generally two stacking methods for lithium batteries. One is to insert a diaphragm between the positive pole piece and the negative pole piece, and form a battery by overlapping the positive pole piece-diaphragm-negative pole piece-diaphragm-positive pole piece. The other is the Z-shaped laminate, which moves the laminate back and forth through a continuous diaphragm, and alternately places the positive and negative electrodes between the Z-shaped diaphragms to form a battery cell. [0003] In the Z-type lamination technology, the diaphragm is wound up in the unwinding mechanism, and after being relea...
