Lithium Battery Galvo Laser Welding Machine

Product Overview

With the rapid development of the new energy industry, the welding quality and efficiency of lithium batteries have become key factors affecting battery production. Traditional welding methods can no longer meet the demands of modern production in terms of efficiency, precision, and consistency.

To address this, ZS Laser has launched a new generation of Lithium Battery Galvo Laser Welding Machine, specially designed for lithium battery welding.The machine adopts a high-precision galvanometer laser output system combined with a three-section semi-automatic hydraulic robotic arm, achieving high-efficiency, stable, and intelligent welding operations.

It is widely used for:

Electric vehicle battery module welding

Energy storage battery pack welding

Cylindrical and prismatic lithium battery sealing welding

Power tool and consumer electronics battery welding

This machine is the ideal choice for small and medium-sized battery manufacturers seeking to enhance production quality and efficiency.

Core Technologies and Advantages

Galvo Laser Output System – Higher Precision, Faster Speed

Stable laser output and rapid response, ideal for complex welding paths;

Spot positioning error less than 0.01mm, ensuring uniform and consistent welds;

Compared to traditional coaxial output structures, it offers a shorter beam path and higher energy utilization;

Especially suitable for fine welding areas such as battery tabs and cell connections.

Three-Section Hydraulic Robotic Arm – Flexible, Accurate, and Easy to Operate

The three-section hydraulic robotic arm independently developed by ZS Laser features a reach of 1500mm, offering both flexibility and rigidity:

Enables precise positioning of the welding head;

Easy movement reduces operator fatigue;

Compact design with a small footprint, ideal for small and medium-sized factory layouts.

One Machine, Multiple Applications – Adaptable to Various Battery Types

By adjusting welding parameters, the machine can meet different welding requirements for various battery types and materials.

Applicable to nickel, aluminum, stainless steel, and copper;

Supports multiple welding processes, including tab welding, intercell connection, and shell sealing;

Truly a multi-functional machine, reducing equipment investment and production costs for enterprises.

Intelligent Control System – Simplifying Complex Welding

The machine is equipped with the PTZJ multifunctional intelligent control system, providing a user-friendly and intuitive interface:

Operators can master welding operations after simple training;

Supports multi-language switching, making it convenient for global customers.

High-Efficiency Water Cooling System – Stable Performance and Longer Lifespan

The system uses the Teyu RMFL-2000 industrial chiller, featuring flow protection and temperature control:
