Abstract

The invention discloses an airflow suspension device and lithium battery production equipment, and relates to the technical field of lithium battery production. The airflow suspension device comprises an outer shell and a fan. The fan is fixedly installed in the outer shell, a through hole is formed in the outer shell, and the fan is used for discharging air outwards through the through hole so that a strip can be suspended on the surface of the outer shell. Compared with the prior art, according to the airflow suspension device, the fan installed in the outer shell and the through hole formed in the outer shell are adopted, so that the influence on the tension of the strip can be avoided, a tension control process is simplified, the tension control precision is improved, the tension control delay is shortened, and the system response is accelerated.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to an air suspension device and lithium battery production equipment. Background technique [0002] At present, in the production process of lithium batteries, it is necessary to use rollers to drive the strips (electrode sheets and separators) to carry out stripping, so as to realize the winding forming or stacking forming of the battery cells. The passing roller can rotate under the drive of the drive motor to drive the strip to move through the friction between it and the strip, and to support and guide the strip. But in this way, the sliding friction between the passing roller and the strip and the moment of inertia of the passing roller will have a greater impact on the tension of the strip, resulting in a complex tension control process, low tension control accuracy, and long tension control delay. The system responds slowly. [0003] In view of this, it i...
