Description

Technical Field

[0001] This utility model relates to the field of battery cell manufacturing technology, and in particular to a battery cell marking and identification device. Background Technology

[0002] The new energy vehicle industry has experienced rapid development and market growth in recent years. As a core component of new energy vehicles, lithium-ion power batteries have also seen rapid development. Simultaneously, the market is continuously placing higher demands on lithium-ion batteries in terms of energy density, lifespan, and safety. Therefore, battery manufacturers must pay closer attention to quality and cost control during the production process, striving to improve product quality and consistency while reducing production costs. Lithium-ion battery cell manufacturing is a crucial process in battery production.

[0003] The position of the four-piece label during cell die-cutting and winding is currently random. When the four-piece label is applied more than 1 meter in front of the marking hole, it will cause the four-piece label to be rolled into the last cell, resulting in material waste of one cell. Adding a marking hole recognition device and placing the four-piece label at a standard position between 2-5 tabs in front of the marking hole will allow for precise stopping of the winding without causing waste.
