With the development of science and technology, lithium-ion batteries are widely used in various electronic devices such as mobile phones, computers and electric vehicles due to their high energy density, long cycle life and no memory effect. Square lithium-ion batteries are particularly suitable for mobile products due to their high voltage and large capacity. With the expansion of application fields, the quality qualification rate requirements for lithium-ion batteries are also increasing to ensure their safety and stability.

[0003] During the processing of lithium batteries, the bending of electrode sheets is an important step. Traditional bending methods often rely on manual bending by workers.

Workers need to spend a lot of time and energy to complete this repetitive work, which not only reduces production efficiency, but also makes workers feel tired after long-term operation, thus affecting the accuracy and quality of bending. Secondly, manual bending requires high operating skills of workers. Due to the particularity of electrode sheet materials and the precision requirements of bending angles, workers need to undergo special training and practice to master the correct operating methods. Improper operation may cause damage to the electrode sheets or inaccurate bending angles, which in turn affects the performance and safety of lithium batteries. Utility Model Content
