New energy power batteries are currently popular products, especially favored in applications such as electric vehicles. Therefore, battery module welding or battery PACK welding has become a popular processing industry for battery manufacturers. The battery PACK automatic laser welding machine (HP-PACK022) developed by SHINHOP Shenzhen Laser Equipment Company in recent years is produced to meet the current needs of the battery module welding industry, compared to traditional.Battery module welding machine, laser automation welding is far ahead in terms of processing efficiency and quality level. Below, we can take a look at the characteristics of this battery module laser welding system.
Battery PACK consists of most small battery modules or directly from battery cells. The battery cells or the cells inside the module need to be connected in series and parallel through busbars or soft connection pieces to form a certain voltage and easily produce finished batteries. Of course, this battery pack not only needs busbars for connection but also requires packaging devices, glue application, IC control, and other auxiliary configurations to become a qualified power battery.
To achieve good battery cell connections, specializedBattery module (PACK) laser welding machineis needed for welding. Currently, the battery cells used for battery PACK mainly include square aluminum shell cells, 18650 cells, and soft pack cells, with square aluminum shell cells being the main type, followed by soft pack and cylindrical cells. Therefore, today we will focus on the welding of square cylindrical cell connection pieces for series and parallel connections.
There are many materials for battery PACK connection pieces, and the specifications vary. For example, there are pure nickel materials, copper-nickel composite materials, aluminum-nickel composite materials, as well as pure aluminum and pure copper materials. Each material has its characteristics, and the thickness and width can differ, meaning they require different laser welding devices. At least there are some differences in welding parameter settings! The HP-PACK022 battery module PACK line laser welding machine developed and produced by SHINHOP Laser Equipment Manufacturer can flexibly adapt to the welding between different materials, making it one of the few manufacturers in the battery welding system that can achieve multi-functionality with one machine. Its various parameters, including spot size, current, and power, can be modulated and controlled, and it can switch freely between pulse and continuous welding. It can even be used for spot welding of battery caps, soft pack battery tabs from aluminum to nickel, and other welding.
Some people may say that there are still many companies engaged in resistance welding on the market, but in fact, these weldings were mainly used for the processing of cylindrical cell connection pieces. For welding aluminum shell square cell connection pieces, these resistance weldings are far from meeting the demand. Moreover, the current 18650 cylindrical cells are also starting to use lasers to enhance their welding quality and safety performance. Therefore, it can be said that in the future, laser welding will be widely used to replace battery PACK module connection piece welding, and the prospects are promising.
For PACK automation welding, we have developed automatic and semi-automatic welding systems. Users can customize their equipment according to their budget or needs, which can achieve manual loading and unloading or robotic automatic loading and unloading production lines.
Characteristics of the laser welding machine (HP-PACK022) system for battery module PACK lines:
1. Welding parameters can be set through the operation interface;
2. Ensure that the weld seam has no leakage after welding;
3. After welding, it meets the pressure resistance test requirements;
4. Weld points are smooth, weld spots are flat, and color is uniform;
5. During the welding process, no damage or impact is allowed on other components;
