Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a polymer lithium battery tab welding mark leveling device. Background Technique

[0002] Lithium polymer battery, also known as polymer lithium battery, is a battery with chemical properties, which has many advantages such as high specific energy, miniaturization, ultrathinness, light weight and high safety. Based on these advantages, lithium polymer batteries can be made into batteries of any shape and capacity, thus meeting the needs of various products. Batteries are divided into positive and negative electrodes. Tabs are metal conductors that lead out the positive and negative electrodes from the battery core. Generally speaking, the ears of the positive and negative poles of the battery are the contact points during charging and discharging.

[0003] Battery tab welding mark leveling is to ensure the reliability and safety of the battery, which can ensure that the connection between electrodes is tighter, thus improving the reliability of the battery. The existing tab welding mark leveling usually adopts the methods of grinding or pressing. Grinding and pressing are respectively leveling by grinding with a grinding roller and pressing with the pressure generated by a pressing plate. These leveling methods are all carried out in one step and are difficult to level step by step and level by level, which may cause over-leveling and damage to the tabs. Therefore, we have designed a polymer lithium battery tab welding mark leveling device. Content of the Utility Model
