Cutting device with good pressing effect for lithium battery aluminum foil machining

Abstract

The invention relates to the technical field of lithium battery aluminum foil machining, in particular to a cutting device with a good pressing effect for lithium battery aluminum foil machining. Thecutting device comprises a device body, wherein fixing plates are fixedly connected to the two sides of the inner wall of the device body, a pressing assembly is movably connected between the oppositesides of every two corresponding fixing plates, pulling assemblies are fixedly connected to the tops of the pressing assemblies, the tops of the pulling assemblies penetrate to the tops of the fixingplates, a connecting plate is fixedly connected to the inner wall of the device body, and the two sides of the interior of the connecting plate are each movably connected with two movable blocks. Thecutting device with the good pressing effect for lithium battery aluminum foil machining has the advantages that the pressing effect on aluminum foil is good, and the aluminum foil is prevented fromwrinkling in the machining process; and besides, limiting structures are arranged and used in cooperation with pressing devices to prevent the position of the lithium battery aluminum foil from deviating in the cutting process, so that the accuracy of the cutting size is guaranteed, the generation of waste is reduced, and use convenience is brought to a user.

Description

technical field [0001] The invention relates to the technical field of lithium battery aluminum foil processing, in particular to a cutting device for lithium battery aluminum foil processing with good compaction effect. Background technique [0002] As we all know, battery aluminum foil is used as a current collector for lithium-ion batteries. Generally, the lithium-ion battery industry uses rolled aluminum foil as a positive electrode collector. Lithium batteries usually have two types of cylindrical and square shapes, and the interior of the battery uses spiral wound The structure is made of a very fine and highly permeable polyethylene film separator material between the positive and negative electrodes. The positive electrode includes a current collector composed of lithium cobaltate and aluminum foil, and the negative electrode is made of graphitized carbon material and copper. The battery is composed of a current collector composed of foil, and the battery is filled w...

Problems solved by technology

[0003] Lithium batteries are widely used in our daily life. The aluminum foil in lithium batteries needs to be cut with a cutting device during production and processing. The cutting device needs to use a compression device to compress it when cutting the aluminum foil of lithium batteries. However, the existing cutting device for lithium battery aluminum foil processing does not have a good compression effect on the lithium battery aluminum foil, which may easily cause wrinkles on the lithium battery aluminum foil, and there is no limit structure to cooperate with the compression device, resulting in lithium battery aluminum foil The position is prone to deflection during cutting, which affects the cutting scale, increases the scrap rate, and is not convenient for users to use
