Aluminum foil slitting device for lithium battery and working method thereof

Abstract

The invention discloses an aluminum foil slitting device for a lithium battery and a working method thereof. The aluminum foil slitting device comprises a carrying table, a first motor and a plurality of sliding mechanisms, wherein mounting plates are arranged at the two ends of the upper portion of the carrying table, and the middle of one mounting plate is sleeved with the first motor. The aluminum foil slitting device has the beneficial effects that a second hydraulic cylinder on a pushing and cutting base drives a cutter to move downwards through a second hydraulic column, aluminum foil is cut into sections through the cutter, the cut aluminum foil falls into a falling box to be stored, the automation degree of aluminum foil slitting work is high through the device, the aluminum foil is slit through the plurality of sliding mechanisms installed on a lead screw, and then the aluminum foil slitting efficiency of the device is greatly improved; and when the aluminum foil moves to the end, close to a hanging frame, of a top plate, a first hydraulic cylinder pushes a pressing plate to move downwards through a first hydraulic column, the aluminum foil is attached and pressed through the pressing plate, the two sides of the aluminum foil are clamped and blocked through two partition plates correspondingly, the moving track of the aluminum foil is more accurate, and the aluminum foil cutting precision and quality of the cutter are greatly improved.

Description

technical field [0001] The invention relates to an aluminum foil cutting device for a lithium battery, in particular to an aluminum foil cutting device for a lithium battery and a working method thereof, belonging to the application technical field of the aluminum foil cutting device for a lithium battery. Background technique [0002] In the process of lithium battery processing and production, aluminum foil is indispensable. Aluminum foil is usually used as the positive electrode collector of lithium ion battery, so that lithium battery has better conductivity, current collection and discharge performance. Before the aluminum foil is wound into the lithium battery, It is necessary to use a slitting device to cut the aluminum foil into sections to ensure that the aluminum foil sections can be wound into lithium batteries faster and more tightly. [0003] The existing aluminum foil slitting equipment for lithium batteries still has great defects in use. The existing aluminum...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing aluminum foil cutting equipment for lithium batteries still has great defects in use. The existing aluminum foil cutting equipment for lithium batteries has a low degree of automation for the aluminum foil cutting process. Time-consuming and labor-intensive, the efficiency of aluminum foil slitting is slow; and after the existing aluminum foil slitting equipment for lithium batteries cuts the aluminum foil, the surface of the aluminum foil end is uneven and often has bulges, which is very inconvenient for the later winding of the aluminum foil section to lithium In the battery; the existing aluminum foil cutting equipment for lithium batteries has poor cutting accuracy and low cutting quality, and can only cut aluminum foil with a specified width, which has great limitations in use.
