Technology Highlights

1. Roller Guide Rail Technology – 20 Years Calibration-Free

Technology Background:
Originally developed for military applications, including naval artillery shell delivery tracks and nuclear reactor fuel replacement systems, this technology requires high stability and precision.

Key Features:

• 20 years Cablibration-free operation – reducing downtime and operational costs

• Reliable for long-term use in demanding environments

2. Ultra-Long Rail Splicing Technology – Up to 200+ Metres

Our ultra-long rail splicing technology enables seamless connections of rails, allowing for continuous lengths of up to 200 metres. This ensures the gantry robot can operate over vast distances without compromising performance.

Key Patented Technologies:

• Patent: "Installation Method for Large Beams"

• Patent: "Adjustment Device for Installing Gantry Robot Rails"

• Patent: "Saddle-Shaped Rail Leveling Tool"

These patents ensure precise alignment and optimal performance for gantry robot systems.

3. High Rigidity with Monolithic Casting

Our gantry robots feature a monolithic casting design for the main body, providing high rigidity and structural integrity. This design eliminates weak points, ensuring superior strength and stability, even under heavy loads.

• Aluminum casting is used for loads up to 300 kg, while steel casting is used for heavier loads.

• The C-shaped structure with rear rack drive ensures balanced force distribution and exceptional stability.

4. Gantry Robot Temperature Compensation Technology

To ensure precision in varying environmental conditions, our robots feature temperature compensation technology. Using temperature gradient data, the system adjusts for thermal distortions, maintaining high-precision positioning throughout operation.

5. Dual Protection Feature

Safety is paramount at STON Robotics. Our dual protection system includes:

• Dual-loop safety PLCs, ensuring real-time monitoring of safety signals

• Elastic collision-resistant blocks at extreme axis positions, absorbing impacts in case of soft limit failures

This system guarantees enhanced safety, even in challenging conditions.

6. Cable Chain Disconnect Device

Our cable chain disconnect device simplifies maintenance by allowing independent disconnection of flexible cables. This means that when cables reach the end of their lifespan, only the cable chain and flexible cables need replacement, reducing downtime and simplifying the maintenance process.

7. Ground-Level Lubrication Pump Maintenance Design

Designed for ease of maintenance, our gantry robots feature ground-level lubrication pumps, eliminating the need for elevated servicing. This allows operators to perform maintenance tasks efficiently and keep the lubrication system in optimal condition for long-lasting performance.

8. Aluminium Profile Cable Chain Trays

Our aluminium profile cable trays offer high rigidity and durability, with wear-resistant strip attachments that enhance cable chain performance. The shock-absorbing strips at the bottom reduce noise and improve the overall lifespan of the system, ensuring smooth and quiet operation.

STON Robotics continues to lead the way in automation innovation, offering high-performance gantry robots for industries across the globe. With our commitment to precision, reliability, and cutting-edge technology, we are redefining the future of industrial automation.
