High-Precision Automated Laser Welding with Dual-Station Vision Positioning

The JUYI Dual-Station Vision Positioning Laser Welding Machine is a high-precision automated welding system designed for efficient and repeatable welding of small and medium-sized metal components.

Equipped with a 1500W single-mode continuous fiber laser, a 1070±10nm laser wavelength, and a high-resolution 1200W-pixel vision positioning system, the machine provides accurate welding position recognition and stable laser output for precision manufacturing.

Its dual-Y gantry structure and dual-station working configuration allow operators to load and unload one workpiece while the other station is being welded. This helps reduce waiting time between production cycles and improves overall equipment utilization.

The X/Y worktable provides ±5μm positioning accuracy and ±2μm repeat positioning accuracy, making the system suitable for applications where consistent welding position and repeatability are critical.

How Does the Dual-Station Vision Laser Welding Machine Work?

The system combines a continuous fiber laser, precision motion platform, and machine vision positioning technology.

The vision system first captures the workpiece and identifies the welding position. The control system then calculates the required welding coordinates and guides the laser head or worktable to the programmed position.

After positioning, the 1500W fiber laser delivers concentrated laser energy to the joint, creating a localized molten pool and forming the required weld.

Working Process

Workpiece Loading → Vision Recognition → Automatic Positioning → Laser Welding → Welding Completion → Workpiece Unloading

The dual-station configuration allows the two work areas to alternate between loading/unloading and welding, making the system well suited for repetitive production.

Vision-guided laser welding is commonly used to compensate for workpiece positioning deviations and improve welding consistency in automated production.

Key Advantages

1. Dual-Station Design for Higher Production Efficiency

The machine features a dual-station working structure, allowing two work areas to be used alternately.

While one station is undergoing laser welding, the operator can prepare or unload the other station.

This can reduce idle time caused by manual loading and unloading and is particularly useful for batch production.

Station B: Loading / Unloading

This operating concept makes the machine suitable for continuous production of repetitive components.

2. 1200W-Pixel Vision Positioning System

The machine integrates a 1200W-pixel vision positioning system to identify the workpiece and welding location.

Compared with relying entirely on mechanical positioning or manual alignment, vision positioning can help compensate for small variations in workpiece placement.

This is particularly useful for:

• Small metal components
• Precision hardware
• Repetitive parts
• Irregular workpieces
• Components with different positioning tolerances

The vision system can help improve positioning consistency and reduce manual adjustment.

3. ±5μm X/Y Positioning Accuracy

The X/Y worktable provides positioning accuracy of up to:

±5 μm

This high positioning accuracy makes the machine suitable for precision welding applications where the welding position must remain consistent from one workpiece to another.

4. ±2μm Repeat Positioning Accuracy

The X/Y worktable provides repeat positioning accuracy of:

±2 μm

High repeatability is particularly important for automated batch welding because the same welding coordinates need to be reproduced accurately across multiple workpieces.

This helps improve:

• Weld position consistency
• Product repeatability
• Production stability
• Automated processing efficiency

5. 1500W Single-Mode Continuous Fiber Laser

The machine uses a 1500W single-mode continuous fiber laser.

The high-quality laser beam provides concentrated energy and stable heat input for efficient metal welding.

Continuous laser output is particularly suitable for:

• Continuous seam welding
• Precision component welding
• Structural welding
• Repetitive production
• Automated welding

6. Stable Laser Output

The laser output power stability is specified at:

< ±2%

Stable laser output helps maintain consistent energy delivery during production.

This contributes to more consistent welding conditions and reduces variations caused by fluctuations in laser power.

7. Gantry Double-Y Machine Structure

The machine uses a gantry-type double-Y structure.

The dual-Y configuration supports the dual-station working concept while providing a stable mechanical platform for precision welding.

A rigid motion structure is particularly important for maintaining positioning accuracy during repeated automated movement.

8. Industrial PC Control

The machine uses an Industrial PC (IPC) control method with dedicated control software.

The control system can coordinate:

• Vision positioning
• Laser output
• Motion control
• Welding parameters
• Workpiece positioning
• Dual-station operation

This provides an integrated platform for automated laser welding production.

9. Water-Cooled Laser Welding System

The machine uses water cooling for thermal management.

Water cooling helps maintain stable operating conditions for the 1500W fiber laser and supporting components during continuous production.

This makes the machine suitable for demanding industrial applications and extended production cycles.
