TECHNICAL FIELD
[0001] The utility model relates to the technical field of electric core welding, specifically to a kind of electric core module welding tooling plate. BACKGROUND
[0002] In the lithium battery PACK process flow, the welding technology of electric core plays a vital role. The success or failure of this link is directly related to the performance and safety of the entire battery pack. Laser welding, as a kind of high-precision and high-stability welding technology, has a decisive influence in the PACK process. Because the connection structure of lithium battery module is usually complex, the laser welding operator must be highly focused during the operation process, and slight carelessness or insufficient inspection may lead to incorrect placement of the connecting piece. This incorrect placement may cause sparking or short circuit phenomenon, resulting in a series of serious consequences.
[0003] Firstly, incorrect placement of the connecting piece may cause damage to the connecting piece itself. The connecting piece is an important component for transferring current between electric cores, and once damaged, it will directly affect the conductivity and overall stability of the battery pack. Secondly, the sparking or short circuit phenomenon may cause the generation of electric sparks, which not only damages other components inside the battery pack, but also poses a threat to the safety of the operator. Electric sparks have extremely high temperature, and once they come into contact with flammable substances, they may easily cause a fire, resulting in incalculable losses. Therefore, in the lithium battery PACK process, the precision and stability of laser welding technology are key factors to ensure the safety and performance of the battery pack.
