Laser cutting technology for lithium battery processing -Lithium - Ion Battery Equipment

We all know that lithium-ion batteries, as the power engine of new energy vehicles, determine the endurance and mileage of new energy vehicles, and the quality of their craftsmanship directly affects the performance of the new energy vehicle market. To this end, the company is also trying to use more advanced processing technology, such as laser cutting technology, to improve the performance of lithium-ion batteries.

Laser cutting technology has the characteristics of controllable processing, high efficiency and high quality, and has a very broad application in industrial processing, such as automobile industry, textile machinery, sheet metal processing, etc. Laser cutting can be divided into four categories: laser vaporization cutting, laser melting cutting, laser oxygen cutting and laser scribing and controlled fracture. Due to the late start of laser technology in my country, the core cutting technology relies on imports, which has led to the slow development of high-end laser cutting in China.(Lithium - Ion Battery Equipment)

The laser cutting machine is the most direct device that reflects the laser cutting technology. It is the laser emitted from the laser, which is focused into a high power density laser beam through the optical path system. The laser beam is irradiated on the surface of the workpiece, making the workpiece reach the melting point or boiling point, while the high-pressure gas coaxial with the beam blows the molten or vaporized metal away. With the movement of the relative position of the beam and the workpiece, the material is finally formed into a slit, so as to achieve the purpose of cutting.

As a new type of sheet metal processing equipment, laser cutting machine and laser cutting machine equipment are being familiar and accepted by the majority of sheet metal processing companies through continuous technological update and process development. High quality, good cutting section quality, three-dimensional cutting processing and many other advantages have gradually replaced traditional sheet metal processing methods such as plasma cutting, water cutting, flame cutting, and CNC punching. According to the difference of laser generators, laser cutting machines on the market can be roughly divided into three types: CO2 laser cutting machines, solid (YAG) laser cutting machines, and fiber laser cutting machines.

Features of laser cutting machine

YAG solid state laser cutting machine

YAG solid-state laser cutting machine has the characteristics of low price and good stability, but the energy efficiency is generally less than 3%. At present, the output power of the products is mostly below 800W. Due to the small output energy, it is mainly used for punching and thin plate cutting. Its green laser beam can be applied in the case of pulse or continuous wave. It has short wavelength and good condensing property, which is suitable for precision machining, especially hole machining under pulse. It can also be used for cutting, welding and photolithography. The wavelength of the laser of the YAG solid-state laser cutting machine is not easily absorbed by non-metals, so it cannot cut non-metallic materials. What the YAG solid-state laser cutting machine needs to solve is to improve the stability and life of lithium-ion batteries, that is, to develop large-capacity and long-life batteries. Optical pump excitation light source, such as the use of semiconductor optical pump can greatly improve the energy efficiency.

Important advantages: It can cut aluminum plates, copper plates and most non-ferrous metal materials that other laser cutting machines cannot cut. The machine is cheap to purchase, low to use, and easy to maintain. Most of the key technologies have been mastered by domestic companies. The price of accessories and maintenance The cost is low, the operation and maintenance of the machine are simple, and the quality of workers is not high.
