　　Lithium battery pack line production equipment

　　The lithium battery pack production equipment is a key device used to assemble individual lithium battery cells into lithium battery packs.

　　Firstly, there are welding equipment, including spot welding machines and laser welding machines. Spot welding machines are mainly used to connect the terminals and connecting pieces of battery cells, achieving series or parallel connection between battery cells. Laser welding machines have higher welding accuracy and efficiency, and are suitable for occasions with higher requirements for welding quality.

　　Next is the detection equipment, such as voltage and internal resistance testers, used to measure the voltage and internal resistance of each battery cell, ensuring the consistency of the battery pack. There is also an insulation withstand voltage tester to test the insulation performance and withstand voltage capability of the battery pack, ensuring safe use.

　　Furthermore, there are assembly equipment, including battery pack casing assembly equipment and wiring harness assembly equipment. The shell assembly equipment encapsulates the battery cell inside the shell, providing protection and fixation. The wiring harness assembly equipment is responsible for connecting the wires and plugs between the battery pack and external devices.

　　In addition, the installation and debugging of a Battery Management System (BMS) equipment are also required. BMS is the core component of lithium battery pack, responsible for monitoring and managing parameters such as voltage, current, temperature, etc. of the battery pack to ensure its safe operation and extend its service life.

　　In the production process, automated conveying and warehousing equipment are also needed to improve production efficiency and material management level.

　　In short, there are various types of production equipment for lithium battery pack lines, and each equipment works together to ensure the high quality, performance, and safety of lithium battery packs.
