Product Attributes

Lithium Battery Laser Welding Machine is high-power laser for precision welding, automation-compatible controls, and ergonomic adjustable platforms. Ensures efficient, high-quality production with minimal heat impact.

Working Principle

The lithium battery laser welding machine is a welding method that uses a laser beam to heat and melt materials. The laser beam is focused on a very small area through an optical system, creating a highly concentrated heat source in a very short period of time at the welding point, causing the welded material to melt and form a strong weld point and seam.

Key Features

Fast Speed: As laser welding is a non-contact method, it allows for rapid welding and improves production efficiency, achieving a 5-10 times increase compared to traditional welding methods.

Low Pollution: Laser welding uses a non-contact welding method, which does not produce any harmful gases or waste during the welding process, making it more environmentally friendly.

Small Heat Affected Zone: Laser welding features high energy density and rapid heating, resulting in a very small heat-affected zone, reducing thermal damage to surrounding materials and effectively improving the accuracy of the parts.

Good Weld Quality: The welds are smooth, free of impurities, uniform and dense, requiring no additional polishing work. It allows for micron-level control of the weld seam, making the welded connections more uniform and reliable.

Application Areas

Connection of positive and negative electrode plates: In the manufacturing process of lithium-ion batteries, multiple layers of thin sheets need to be stacked in a certain order and connected to each other through laser welding technology, ensuring an even distribution of battery pressure.

Sealing of electrolyte injection holes: Lithium-ion batteries require electrolyte to operate, so some injection holes need to be made on the battery casing. Laser welding technology can complete the sealing process in a short time, making the sealing process more stable and firm.

Sealing of battery cover plates: The sealing of battery cover plates is one of the important measures to ensure the battery is waterproof, dustproof, and corrosion-resistant. Laser welding technology can directly weld the cover plate and the casing, avoiding issues such as less than ideal welding quality or unnecessary gaps that may occur with traditional welding processes.

Connection of battery cells: It can achieve the connection between battery cells, ensuring the reliability and stability of the connection. Laser welding can achieve high-strength weld seams, improving the overall performance of the battery pack.

Connection of battery modules: It can be used for different battery connection methods, ensuring electrical and mechanical connections between modules. The high precision and efficiency of laser welding make module connections more secure and reliable.
