Small turret-type double-station automatic winding and unwinding device

Abstract

The invention discloses a small turret-type double-station automatic winding and unwinding device. The small turret-type double-station automatic winding and unwinding device comprises a turret framework; the turret framework is arranged on a bottom frame; each of supporting shafts at the two ends of the turret framework is pivoted through a supporting leg; a first clamping mechanism and a secondclamping mechanism are arranged on the two sides of the turret framework correspondingly and are fixedly arranged on corresponding supports; all the supporting shafts penetrate out of the supports correspondingly; the one supporting shaft is connected with a synchronous shaft detection device; the other supporting shaft is connected with a turret transmission mechanism; the turret transmission mechanism drives the turret framework to rotate; the synchronous shaft detection device is used for detecting a rotation angle of a turret; and an unwinding automatic tape splicing device used for carrying out tape splicing on old and new material coils is arranged at a space, located below the turret framework. The automatic-driving, automatic-tape-splicing and double-station nonstop operation can be achieved, and the small turret-type double-station automatic winding and unwinding device has good automation property.

Description

technical field [0001] The invention relates to the field of battery rolling mechanisms, in particular to a winding and unwinding device applied to the rolling process of lithium battery production. Background technique [0002] With the development of human civilization, the demand for energy is increasing, and traditional energy resources such as oil and coal are facing exhaustion. At the same time, the consumption of traditional energy has also brought serious environmental pollution problems. Under the double pressure, human beings' thirst for new energy is becoming more and more urgent. As the most widely used clean energy at present, electric energy is naturally favored by human beings in every possible way. As a power storage unit, lithium batteries have also ushered in explosive development. [0003] In the production of lithium batteries, in order to improve the density and thickness consistency of the surface material of the battery pole piece, a rolling process m...

Problems solved by technology

This way of working is inefficient, the equipment start-up rate is low, and the labor intensity of workers is high.

In recent years, some new large-scale equipment in some battery factories has been equipped with double-station automatic rewinding and unwinding, but the pole piece material rolls are relatively large, which is not suitable for some small-scale battery factories or manufacturers who are upgrading. The higher cost of high-end equipment will also bring a greater burden to manufacturers
