In conclusion, the automation of spot welding between lithium-ion battery cells and sheet metal connectors using an Arduino microcontroller has been successfully implemented. The machine was designed to move in three degrees of freedom to accurately place the welding in the desired location.
Laser welding is widely used in lithium-ion batteries and manufacturing companies due to its high energy density and capability to join different materials. Welding quality plays a vital role in the durability and effectiveness of welding structures. Therefore, it is essential to monitor welding defects to ensure welds quality.
We found that the the spot welding which is one of the very vital process carried in the manufacturing of lithium ion battery packs is performed manually in most of the small scale Li-ion battery pack manufacturing industries.
Kim et al. (2018) developed an automated welding system for lithium-ion battery pack assembly. The system consisted of a robotic arm and a vision system for detecting the location of the cells and connectors. The system was tested on various cell and connector configurations and demonstrated consistent and reliable welds.
Moreover, the high-volume production requirements, meaning the high number of joints per module/BP, increase the absolute number of defects. The first part of this study focuses on associating the challenges of welding application in battery assembly with the key performance indicators of the joints.
