Description

Technical Field

[0001] The utility model relates to the technical field of tab processing, in particular to a polymer battery core arc tab cutting device. Background Art

[0002] The tab is a raw material for lithium-ion polymer battery products. For example, the mobile phone batteries, Bluetooth batteries, laptop batteries, etc. we use in our lives all need tabs. The battery is divided into positive and negative poles. The tab is a metal conductor that leads the positive and negative poles out of the battery cell. In layman's terms, the tabs at the positive and negative poles of the battery are the contact points during charging and discharging. This contact point is not the copper sheet we see on the outside of the battery, but a connection inside the battery.

[0003] In the production process of polymer batteries, a cutting device is needed to cut the pole ears. However, some existing cutting devices have poor fixing effect on the pole ears. The pole ears are prone to shaking during cutting, resulting in uneven cutting surfaces of the pole ears. At the same time, the cutting knife is prone to lift up the cut portion of the pole ears when moving upward, affecting the cutting effect. Therefore, a polymer battery cell arc-shaped pole ear cutting device is proposed. Utility Model Content
