Abstract

The invention relates to the technical field of lithium battery manufacturing, in particular to a leveling device. The leveling device comprises a coating machine drying oven, a first guide roller, asecond guide roller and a passing roller; the first guide roller is arranged at an outlet of the coating machine drying oven; the second guide roller is arranged at the front end of the outlet of thecoating machine drying oven; the first guide roller and the second guide roller are arranged on the same plane; a polar coiled strip is located above the first guide roller and the second guide roller; and the passing roller is connected to the upper portion of the polar coiled strip in an abutting mode and can move up and down relative to the polar coiled strip so as to enable the polar coiled strip to be conveyed in a leveling mode. The leveling device has the advantage that the technical problems that in the prior art the structure of coating equipment is relatively complicated, the risk that foil folds are generated again occurs, and the height of the passing roller on the coating equipment cannot be timely adjusted can be solved.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing, in particular to a leveling device. Background technique [0002] Lithium-ion battery (later referred to as lithium battery) has the advantages of high voltage, high energy density, high safety, low self-discharge rate, etc., and is a promising new energy source. With the further development of science and technology, energy issues and environmental issues have become increasingly prominent, and people's requirements for lithium batteries are getting higher and higher. In the application fields of electric vehicles, solar energy storage batteries, energy storage power stations, smart phones, laptop computers, etc., lithium batteries are required to have high capacity, high rate, high stability, high safety and high consistency. These key requirements of lithium batteries are all related to the negative electrode coating, so it is very important to improve the flatness of th...
