Abstract

The invention discloses a pouch lithium battery tab cutting device. The tab cutting device comprises a base; a fixed plate is fixedly connected with the surface of the base; a first linear slide railis fixedly connected with the upper side of the fixed plate; an upper jacking bearing cushion is fixedly connected with the upper side of the sliding end of the first linear slide rail; a first air cylinder is fixedly connected with the upper side of the fixed plate; a protruding end of the first air cylinder is fixedly connected with one side of the upper jacking bearing cushion; the upper jacking bearing cushion is a ladder-shaped block; a supporting plate is fixedly connected with the upper side of the base; and a second linear slide rail is fixedly connected with one side of the supportingplate and is fixedly installed via a bolt. A compaction buffer structure is arranged so a cell of a lithium battery is convenient to position precisely. The cutting process is stable, cutting tools are precisely matched, and a tab cutting burr and a roll rim can be easily controlled; and an upper cutting tool and a lower cutting tool are connected via a bolt, so the cutting tools is convenient toreplace rapidly and the device can improve the cutting quality of a product.

Description

technical field [0001] The invention relates to the technical field of lithium battery tab processing, in particular to a soft-pack lithium battery tab cutting device. Background technique [0002] Tabs are a raw material for lithium-ion polymer battery products. Cell phone batteries, Bluetooth batteries, notebook batteries, etc. used in daily life all need to use tabs. The battery is divided into positive and negative poles, and the tabs are the metal conductors that lead the positive and negative poles out of the battery. In layman's terms, the ears of the positive and negative poles of the battery are the contact points when charging and discharging. This contact point is not the copper piece we see on the outside of the battery, but a connection inside the battery. [0003] Soft-pack ternary power lithium-ion battery, the tab is an important part of the lithium battery, in order to match different products, the tab needs to go through a cutting process, but at this sta...
