With the rapid development of the new energy industry, power batteries, as the core components of new energy vehicles, have continued to advance in their manufacturing technology. Due to its advantages of high precision, high efficiency, and low thermal impact, laser processing machines have gradually become important equipment in the manufacturing process of power battery adapter sheets.This article will discuss the application and advantages of laser fabrication machines in new energy power battery adapter sheets.

Ⅰ. Working Principle of Laser fabrication Machine
Laser fabrication is a fabrication method that uses high energy density laser beam as a heat source. After the laser beam is focused by the focusing mirror, it can generate high temperature in a small area. This melts and bonds the materials to be welded together.Laser fabrication has the characteristics of non-contact, high precision and low heat input. This makes it suitable for precision manufacturing.
Ⅱ. The Function of Power Battery Adapter Piece
The power battery adapter is an important component that connects the battery cells and battery modules. It is usually made of aluminum or copper. Its main function is to connect multiple battery cells in series or parallel to achieve current conduction and voltage stability. Therefore, the fabrication quality of the adapter piece directly affects the performance and safety of the power battery.
Ⅲ. Application of Laser fabrication Machine in Adapter Sheet Manufacturing
The application of laser welding machines in the manufacturing of power battery adapter sheets is mainly reflected in the following aspects:
1.Material adaptability:
Commonly used materials for power battery adapter sheets are aluminum and copper. These materials have high reflectivity and high thermal conductivity, making it difficult to achieve high-quality fabrication using traditional fabrication methods. The laser fabrication machine can effectively weld these highly reflective materials by adjusting the laser power and pulse parameters to ensure fabrication strength and reliability.
2.High fabrication precision:
The fabrication of adapter plates usually requires high precision to avoid positional deviations during battery assembly. The laser fabrication machine can achieve micron-level positioning accuracy and precisely control the fabrication path and fabrication point position through computer control to ensure fabrication consistency and accuracy.
3.Small heat affected zone:
Laser fabrication has a small heat input and can quickly heat and cool in local areas, reducing the thermal impact on the material during the fabrication process. This feature is particularly important for heat-sensitive power battery materials, which can avoid material deformation and performance degradation during the fabrication process.
4.High degree of automation:
Laser fabrication machines can integrated with automated production lines to achieve fully automatic fabrication operations. By combining with robots and sensors, online inspection and quality control can be achieved, improving production efficiency and the consistency of fabrication quality.

Ⅳ. Application Cases of Laser fabrication Machine
In practical applications, laser fabrication machines have widely used in the production of power batteries by many new energy vehicle manufacturing companies. For example, a well-known electric vehicle manufacturer uses laser fabrication technology to weld battery adapter sheets, achieving an efficient and stable production process. Laser fabrication not only improves fabrication quality, but also significantly reduces production costs and equipment maintenance expenses.
Ⅴ. Future Development of Laser fabrication Technology
With the continuous advancement of laser technology, laser fabrication machines have broad application prospects in the field of new energy. In the future, laser fabrication machines will develop in the following directions:
1.Higher fabrication precision:
By introducing more advanced lasers and optical systems, nanometer-level fabrication precision achieved to meet higher requirements for fabrication processes.
2.Intelligent and digital:
Combining artificial intelligence and big data technology to achieve intelligent control and optimization of the fabrication process, and improve fabrication quality and production efficiency through data analysis and machine learning.
3.Multifunctional integration:
Integrate laser fabrication with other processing techniques (such as cutting, marking, etc.) in the same equipment to achieve integrated production and further improve the flexibility and efficiency of the production line.

Final Thoughts
With its unique technical advantages, laser fabrication machines have shown great application potential in the manufacturing of new energy power battery adapter sheets.
