Cobot type Automatic laser welding robot

Equipment overview

Driven by the increasing demand for efficient and high-quality welding processes in manufacturing, laser welding robots have emerged as a core component in intelligent production lines. These robots integrate advanced laser technology with high-precision robotic arm systems, offering advantages such as high welding speed, superior weld quality, and a high degree of automation. They are suitable for a variety of metallic materials, including stainless steel, carbon steel, and aluminum alloys, and are widely used in industries such as automotive manufacturing, rail transportation, construction machinery, sheet metal processing, and new energy.

Key Features:

High-Precision Laser Welding:

Utilizes a high-energy density laser beam to achieve deep penetration welding, resulting in strong and aesthetically pleasing weld seams, minimal heat-affected zone, and extremely low product deformation.

Fully Automated Intelligent Operation:

Achieves multi-station and multi-trajectory automated welding through offline programming or teach pendant operation, significantly improving production efficiency and consistency.

High Flexibility and Wide Adaptability:

Welding paths and parameters can be flexibly adjusted according to different workpiece shapes and materials, adapting to complex structures and irregular component welding requirements.

Stable and Reliable, Reduces Labor Costs:

Long-term continuous operation with stable quality significantly reduces reliance on highly skilled welders, lowering labor and management costs.

System Composition:

The automated robotic laser welding system consists of an industrial robot, laser source, optical fiber, chiller, welding head, control system, electronic fence, dust removal system, and safety protection facilities.

Collaborative Robots：

The collaborative robot specially designed for laser welding is equipped with robot dragging and anti-collision functions, which is suitable for human-machine collaborative control. The built-in laser welding process enables the algorithm to optimize the underlying laser welding process. The advanced servo control system is used to achieve high-precision movement. The compact structure, high-rigidity and lightweight body enable fast response and low-inertia movement.

Robots Parameters：

Laser welding machine:

The air-cooled laser welding machine is a high-power fiber laser with the characteristics of high electro-optical conversion efficiency, compact size, good beam quality, and maintenance-free. This system uses a 25um-50um small core diameter optical path, with a small spot and strong penetration. From the perspective of power density, at the same power, the thinner the core diameter, the higher the laser brightness and the more concentrated the energy.

Laser Parameters:

Laser welding head:

1. Features a unique integrated cooling structure and special airflow design, effectively protecting the nozzle and lenses.

2. The integrated body design includes multiple sets of protective lenses, ensuring a clean and sealed lens barrel to prevent dust contamination of the optical lenses.

3. The laser welding head offers a variety of welding spot options, selectable based on different materials and welding requirements.

4. The welding head's spot size is adjustable, allowing for flexible control over penetration depth and weld bead width.

5. Equipped with a robot-specific intelligent wire feeder, providing precise wire feeding for high-precision filler wire processes.

High-precision positioner (optional):

The laser welding positioner is an efficient auxiliary equipment used in conjunction with the laser welding system. Its main function is to optimize the welding angle and welding trajectory by accurately rotating, flipping or positioning the workpiece, thereby achieving high-quality and efficient automated welding operations.

The positioner can freely adjust the welding posture according to the structural characteristics of different workpieces. In conjunction with the robot laser welding gun, it greatly improves the welding accuracy and finished product consistency. It is an indispensable and important equipment for achieving full-position welding of complex workpieces.

Welding robot ground rail (optional):

The welding robot ground rail (also known as ground rail, robot slide) is a key expansion unit to improve the robot's operating range and flexibility. By installing a linear rail on the ground, the robot can move along the track with high precision, achieving continuous automated welding in multiple stations and multiple areas, greatly improving the flexibility and efficiency of the production line.

The ground rail system not only expands the robot's working radius, but can also be used with a variety of welding processes such as laser welding, arc welding, and spot welding. It is an indispensable and important equipment in the intelligent welding production of large workpieces and large components.
