Main technical function
1. The steel bar sampling robot automatically samples the bar at the cooling bed and has the sample size, sample preparation, negative difference measurement, transportation, and wind tunnel delivery of the hot bar.
2. It has the ability to selectively sample the double ruler on the cooling bed; identify the end information of the bar wire; and automatically identify the end information of the bar wire to find a suitable sampling position.
3. Automatically grab the appropriate position of the sample, and automatically cut the sample.
4. Possess the data related to the cold state size of the test sample bar surface
5. The system has diagnostic function. When the system encounters a fault, it will alarm and deal with it, and it has a manual function. At this time, manual troubleshooting and manual sampling operations are required.
6. The system provides automatic positioning function, which can automatically locate the end of the bar and identify the length of the sample.
7. There must be protective measures around the robot platform to ensure that the system is not affected by other factors during operation. Once the protective door is opened, the mechanical arm needs to stop running to ensure the safety of personnel entering the protective work area.
8. It is interlocked with the stepping cooling bed, and it acts simultaneously with the stepping cooling bed at the same time of sampling, and the stepping cooling bed does not need to stop working when working.
9. The protective device is designed according to the environmental conditions of the working area, with extremely high reliability and extremely low maintenance rate.
10. Multiple detection and protection measures fully avoid equipment damage caused by equipment failures and human operation, reduce maintenance costs and improve production efficiency.
11. The whole process of cutting, sampling, feeding, testing, and unloading is automatically completed, which can completely avoid the impact on the physical and mental health of the operator; the operator does not directly contact the material, which will cause pollution to the raw material.
12. High efficiency can meet the sampling frequency of 20 minutes/time on site (customizable by users)
Equipment overview
In the sample collection area on the cooling bed, the rebar is still in a high temperature state, the steel temperature is about 800°C-1050°C, and the air temperature also exceeds 100°C. The working environment is harsh. Due to the non-smooth TMT surface with the rib and the structural characteristics of the cooling bed, the rebar has the risk of splashing and hurting people during the operation of the cooling bed, which is easy to cause casualties. Sampling at the bar and wire plant is now done manually. Manual operation has the following problems:
1) The sampling cannot be standardized, and the sampling lengths of different operators vary greatly;
2) The labor cost is high and the efficiency is limited;
3) The temperature of the site is high and the environment is slightly harsh. There is a certain risk in personnel sampling, and the labor intensity is high. After sampling with a robotic hand, the labor intensity of workers can be greatly reduced and the safety factor can be improved.
This system is mainly designed to solve the problem of manual sampling in the bar workshop. It is a highly automated and intelligent control system. It is installed at one end of the bar line stepping cooling bed. The system can completely replace manual sampling and ensure the reliability and accuracy of sampling, timeliness, and at the same time, after water-cooling the sampled samples, the card size and surface quality are measured, replacing manual single repetitive work, and improving work efficiency.
