Description

Technical Field

[0001] The present application relates to the technical field of battery production, and more specifically, to an all-in-one machine for battery cell stickers and nickel strip welding. Background Art

[0002] With the transformation of the global energy structure and the vigorous development of the new energy vehicle industry, the demand for batteries has increased significantly, especially the widespread application of lithium batteries in electric vehicles, energy storage systems and portable electronic devices, making efficient and accurate battery production equipment the key to the development of the industry. In the manufacturing process of lithium batteries, the battery assembly link is particularly important, among which the positive terminal sticker of the battery cell, the welding of nickel strips and the series and parallel connection of the battery cell are the core processes to ensure the performance and safety of the battery pack.

[0003] Specifically, during the assembly of lithium batteries, the positive terminal sticker of the battery cell is used to identify the polarity of the battery cell, ensuring that the positive and negative poles of the battery cell can be accurately identified and connected during battery assembly. The accuracy of this link directly affects the assembly efficiency of the battery and the safety performance of the subsequent battery. In the existing production process, the attachment of the positive terminal sticker of the battery cell mostly still relies on manual operation. Although this method can meet basic production needs, under the conditions of high production and high precision requirements, manual stickers are prone to inaccurate labeling, low production efficiency and poor consistency.

[0004] Nickel bar welding is another key process in battery assembly. It is mainly used to connect multiple battery cells into a battery pack. The current transmission channel between the battery cells is formed by welding nickel bars. The quality of nickel bar welding directly affects the current output stability, temperature rise control and overall safety of the battery pack. In traditional production processes, nickel bar welding usually relies on manual operation. Operators manually weld the battery cells, but manual errors and improper operation may lead to problems such as loose welding, uneven welding points or short circuits, thereby affecting the service life and safety of the battery.

[0005] As the requirements for lithium battery performance continue to increase, especially in the fields of electric vehicles and energy storage equipment, the requirements for battery safety, reliability and stability are becoming more stringent, and the traditional manual operation method has gradually revealed its limitations. Therefore, it is urgent to introduce more automated and intelligent production equipment to replace traditional manual operation in order to improve production efficiency, reduce human errors and ensure the high quality of battery packs.
