Cold Bed Robotic Automatic Sampling & Testing System

The Definitive Solution for Intelligent Upgrading in the Metallurgical Industry

In large-scale metallurgical bar production, cold bed sampling is a critical quality control step. Long-term reliance on manual sampling creates persistent pain points: high-temperature working conditions, repetitive labor, low operational efficiency, poor precision control, non-standard data recording, and limited traceability. These challenges have become major barriers to production line intelligence and efficiency gains—a problem solved by the cold bed robotic automatic sampling and testing system.

Engineered for the harsh, high-demand environments of metallurgical production (extreme temperatures, heavy dust, high-speed production cycles), this fully automated system replaces manual labor for bar sampling and testing. It adapts to a wide range of bar specifications, withstands extreme ambient temperature fluctuations, and delivers a seamless, end-to-end automated workflow—from plasma cutting and sample cooling to fixed-length processing, surface inspection, and real-time data uploads. The result: a more efficient, accurate, and controllable cold bed sampling process that elevates overall quality control for metallurgical bar production.

Core Configuration & Standardized Workflow

Core Hardware

• Multiple six-axis industrial robots paired with fully sealed servo ground rails: precise, fast collaborative operation for sampling, handling, and cutting
• Integrated professional functional units: plasma cutting system, cooling water tank system, material splitting system, fixed-length sawing system, and surface testing system (end-to-end closed-loop workflow)
• High-end industrial PLC main controller with high-speed industrial communication protocol: interlocked control of all units for stable system operation and accurate instruction transmission (ideal for high-speed metallurgical production)

Standardized Automated Workflow

1. Visual positioning system identifies bar end faces and locks sampling points when the system receives a sampling signal or reaches the preset time
2. Sampling robot moves synchronously with the cold bed; plasma cutting system cuts the bar, and mechanical gripper grasps the sample
3. Sample bar is transferred to the cooling water tank system for professional cooling (ensures subsequent testing precision)
4. Handing robot moves the cooled sample to the material splitting system for splitting and centering (multi-slitting bars)
5. Split/centered sample is sent to the fixed-length sawing system for precise cutting to meet testing specifications
6. Fixed-length sample is transferred to the surface testing and meter weight measurement systems for comprehensive precision testing (surface quality, actual meter weight, weight negative deviation, etc.)
7. Tested sample is automatically collected to a designated area; all data is uploaded to the system backend in real time for storage and traceability—system immediately initiates the next sampling cycle
