Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing, in particular to a lithium battery electrode material processing and cutting device. Background Art

[0002] During the battery production process, the electrode sheets need to be installed in the battery. In order to make the electrode sheets conform to the battery size, a cutting device is needed to cut the electrode sheets. However, when cutting, the existing cutting device will deform the electrode sheets in the cutting direction due to the softness of the electrode sheets, thus causing the corners of the electrode sheets to bend.

[0003] In the prior art, a Chinese patent document with publication number CN220362052U is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a lithium battery electrode sheet cutting device, which relates to the field of potassium battery processing technology, comprises an operating table, a group of first columns are fixedly installed on the middle part of the upper surface of the operating table, a first slide groove is provided inside the first column, a cutting assembly for cutting the electrode sheet is movably installed inside the first slide groove, holding assemblies for stabilizing the electrode sheet are fixedly installed on both sides of the cutting assembly, feeding assemblies for automatic loading are fixedly installed on both sides of the upper surface of the operating table, and a cutting groove is provided in the middle part of the upper surface of the operating table.

[0004] In order to solve the problem that the electrode sheet is relatively soft, causing the electrode sheet to deform in the cutting direction and thus causing bending at the corners of the electrode sheet, the existing technology uses an overpressure holding plate and an operating table to flatten the electrode sheet at the current cutting point. However, the debris produced by the cutting may be left on the processing table, which requires manual cleaning, otherwise it will affect the movement and cutting of the next electrode material. Utility Model Content

[0005] The purpose of the utility model is to provide a lithium battery electrode material processing and cutting device to solve the problems raised in the above background technology.

[0008] The cutting device comprises a cutting unit and a pressing unit, and the cutting unit is fixedly installed in the middle of the top surface of the supporting assembly.
