3. Intelligent Sampling: Trinity of Precision, Efficiency, and Automation
3.1 Core Functional Advantages
- Sampling Standards: Strictly complying with steel mill quality control requirements, it automatically collects 2 sets of samples every 15 minutes. The sample length can be flexibly set within the range of 400mm-1500mm (max.), and the single sampling completion time is only 90 seconds (start and end standards can be negotiated and determined according to on-site processes). The sampling efficiency is more than 3 times higher than manual sampling.
- Dual Operation Modes:Automatic Mode: Deeply linked with the production unit, it starts operation immediately upon receiving the unit’s start command, requiring no manual intervention throughout the process. It can achieve 24/7 continuous sampling, perfectly adapting to large-scale continuous production scenarios.Manual Mode: Equipped with functions such as emergency stop button, one-key return to original position, and single equipment locking, supporting manual trigger sampling (presettable target fixed-length position), facilitating equipment commissioning, maintenance, and sampling operations under special working conditions.
- Precision Guarantee: Equipped with a high-definition machine vision system, it accurately locates the end position of the profile through image recognition technology, guiding the robot to achieve millimeter-level sampling positioning; the customized non-slip fixture adapts to profiles of different cross-sectional shapes, with adjustable clamping force, ensuring stable profile positioning without displacement during sampling and avoiding profile deformation caused by excessive clamping.
- Quality Controllability: The straightness deviation of the profile after sampling is controlled within the industry standard range (allowable bending degree can be customized according to customer needs), and the sample integrity is high, which can be directly used for subsequent quality verification links such as material testing and mechanical performance testing.
3.2 Concise and Efficient Operation Process
- Trigger Start: After the control system receives the unit linkage signal, timing signal, or manual trigger signal, it automatically starts the sampling program.
- Positioning and Clamping: The machine vision system quickly identifies the end position and specifications of the target profile, the robot moves to the sampling station, and the customized fixture accurately clamps the profile.
- Following and Cutting: The robot moves synchronously with the cooling bed, and the plasma torch completes precise cutting according to the preset length. During the cutting process, it real-time monitors the flame temperature and cutting speed to ensure a flat cut.
- Sample Collection: After cutting, the robot carries the sample to the collection box area and places the sample stably to avoid sample collision and deformation.
- Reset and Standby: The robot automatically returns to the original position, sends an operation completion signal, and waits for the next sampling command, realizing a full closed-loop operation.
4. Safety and Layout: Balancing Practicality and Humanized Design
4.1 Safety Protection System
A fully enclosed protective railing is installed around the equipment, equipped with safety door locks interlocked with the unit’s online emergency stop. Once someone enters the operation area by mistake, the equipment immediately shuts down and triggers an audible and visual alarm; a high-temperature resistant and impact-proof protective panel is set in the operation area to further ensure personnel safety.
4.2 Flexible Layout Options
The system is installed on the rolling line side of the cooling bed inlet, providing two optimized layout choices—side installation of the cooling bed (saving end space, suitable for narrow and long workshops) and end installation of the cooling bed (shorter sampling path, higher efficiency). The final layout can be determined according to actual conditions such as the casting range of the fixed-length end on-site and the equipment installation space (customers need to provide on-site environment layout videos and equipment drawings of the cooling bed area).
4.3 Operational Convenience
The operation console is located in the quality laboratory, equipped with a high-definition touch screen that can real-time display sampling progress, equipment operation status, fault alarms, and other information; at the same time, an emergency operation panel is installed on-site to facilitate staff to quickly handle emergencies without traveling back and forth to the laboratory.
