Lithium battery explosion-proof valve welding equipment-automatic laser welding machine
The explosion-proof valve of the battery is a thin-walled valve body on the battery sealing plate. It is usually used as an explosion-proof device for lithium-ion batteries by scoring or welding an explosion-proof film. When the temperature of the battery rises, the gas inside the battery expands and the pressure increases to a critical value , Nicks or de-soldering or cracking of the explosion-proof film, remove the gas and reduce the air pressure, so as to avoid the explosion of the lithium battery. For the welding of lithium battery explosion-proof valves, the process requirements are very strict. The editor today introduces an automatic laser welding machine that can be used for the welding of lithium battery explosion-proof valves.
The automatic laser welding machine can quickly realize the welding of the explosion-proof valve, with high welding efficiency and good sealing performance. It can realize high-speed and high-quality welding, with high welding stability, welding efficiency and good product rate.
Advantages of automatic laser welding machine:
1. It has a high aspect ratio, small weld width, small heat-affected zone, small deformation, and fast welding speed.
2. The welding seam is smooth and beautiful, and no treatment or simple treatment procedures are required after welding.
3. The welding seam is of high quality and no porosity, which can reduce and optimize the base metal impurities, and the structure can be refined after welding.
4. The weld strength and toughness are at least equivalent to or even more than the base metal
5. Laser welding does not use fillers, the weld is beautiful and narrow, and the performance of the weld area is better than that of the base material
6. It can be precisely controlled, the focus spot is small, high-precision positioning is possible, and it is easy to realize automation
