1. Principle of lithium battery laser welding machine

Laser welding technology is a highly precise welding method. Its principle is to use a laser beam to rapidly heat the material to reach the melting point and welding temperature, and then implement the welding process. Lithium battery laser welding machine is also a kind of battery component welding equipment that applies laser welding technology. It is mainly based on the optical characteristics of the laser. It reflects and focuses the laser beam through the mirror surface, causing it to produce high-temperature melting on the surface of the lithium battery component.

During the laser welding process, the laser beam will be absorbed and reflected when irradiating the material. The reflectivity depends on the optical properties of the material surface, such as light reflection and light absorption capabilities. For metal materials, the laser is mainly absorbed and the light energy is converted into heat energy, causing the material to heat up rapidly and melt to form a fluid area. When the laser beam stops irradiating, the material will be rapidly cooled and solidified to form a welded joint.

2. How the lithium battery laser welder works

The working method of the lithium battery laser welder is developed based on the optical properties and heat conduction properties of the laser and battery components. Its main working processes include:

1. Adjust welding parameters, such as power, repetition frequency, wavelength, etc., and optimize the laser.

2. Adjust the laser beam through optical elements such as lenses and reflective prisms, and guide it to the welding position of the battery assembly.

3. The laser beam is absorbed by the surface of the battery component, forming a molten pool area, and generates steam, bubbles and other phenomena in this area to quickly melt and weld different positions of the battery component.

4. After each welding position is completed, the laser beam stops irradiating, and the battery assembly is quickly cooled and a welded joint is formed.

With lithium battery laser welding machines, efficient, precise and reliable welding of battery components of various shapes, materials and specifications can be achieved. At the same time, lithium battery laser welding machines have the advantages of fast welding speed, no pollution, cleanliness, and low energy consumption, and are suitable for the production of battery components in electric vehicles, power tools, aerospace and other fields.

In short, the lithium battery laser welder is a high-end equipment that combines laser technology with battery component welding principles and has broad application prospects and market demand.
