A few days ago, STEP, a high-quality robot brand, announced a technological breakthrough: the main product of the palletizing robot, SP120/2400, achieved a beat rate of 1,000 packs/hour, which is far ahead of domestic robot brands. International leading level. What kind of technological breakthroughs have helped STEP robots gain such hard-core strength? This article reveals the mystery behind it for you.

Let's first analyze the timeline of a single beat. The incoming material is 1-line or multi-line confluence, and 1 robot corresponds to 2 pallets. The robot needs to carry out the handling at a 90-degree angle, which is the actual working condition of most bagged goods. In this working condition, to achieve a beat of 1000 bags/hour, each beat is only 3.6 seconds, of which the time for gripping the jaws is 0.3 seconds, and the time for opening the jaws to putting down the bags is 0.35 seconds. Walking between the position to be grasped and the stacking position twice, the time is only 2.95 seconds, and the single time is only 1.475 seconds. There are quite high requirements for the running speed of the robot. It is necessary to race against the stopwatch in all links to achieve it. Such a technological breakthrough. 

The STEP robot R&D and control team started with the algorithm and optimized the dynamics algorithm to allow the robot to obtain greater acceleration and improve the dynamic response characteristics of the robot; the multi-path forward-looking smooth algorithm was adopted to ensure the continuous growth of the speed planning and improve the robot's Beats in short-path conditions; the vibration suppression algorithm of the servo provides a guarantee for further speed improvement and speed stability, and at the same time reduces the acceleration and deceleration changes of the motor in the trajectory planning of the intermediate transition path, and improves the life of the motor reducer. The performance improvement in the robot's core algorithm and motion control is the most critical step to achieve beat improvement.

Improve motion performance through load recognition and model adaptation algorithms

At the same time, the mechanical team replaced the imported brand motor with stronger overload capacity and more stable performance for the SP120/2400 robot, providing the robot with an efficient and stable power system. In addition, the improvement of IO signal processing efficiency ensures that the robot spends less time in the communication link.

Robot technology is a multi-disciplinary integration of machinery, electricity, software, and communications. Technological breakthroughs require all-round collaboration. A single beat runs within 3.6 seconds, achieving a high-speed beat of 1,000 packs per hour.

Zhou Shuopeng, General Manager of STEP Robotics: As a high-tech industry, the core competition of industrial robots is competition in the technical field, and achieving technological leadership is a prerequisite for becoming an international brand. STEP adheres to the strategic planning of "replacing imports by benchmarking imports" and insists on product R&D and market development by benchmarking international brands. It has established R&D centers in Shanghai, Shenzhen, Germany and Japan, and established a high-quality R&D team with a complete discipline structure. , the purpose is to obtain the key technology of robots through original technical research, achieve technological leadership, and then gain market recognition through differentiated competition in market segments. Robots are high-tech products, and the core of market competition is technical competition. In the era of increasing pursuit of quality, it is fundamental for robot companies to do research and development in a down-to-earth manner to achieve technological leadership. The investment in technology, talents, and capital in the robot industry is a long-term cycle. It has been more than half a century of continuous investment to achieve today's international giants. Due to the lack of labor force and individual demand caused by the aging population, the robot industry presents a long-term and high-growth trend. The track of the robot industry is very long and it is a protracted long-distance race. Only by continuing to invest in research and development and giving full play to the bonus of Chinese engineers Only in this way can we make steady progress and achieve China's own robot brand.

The R&D team and engineering team of this breakthrough have passed long-term and comprehensive experiments and tests, from components to complete machines, from software to hardware, from control systems to servo systems, and have finally achieved impressive results. Reassuring. The results of these technological breakthroughs will be applied to the full range of STEP products in the future to further improve the product quality of STEP robots and create better benefits for customers. This is a technological breakthrough for STEP robots, and it is also a technological breakthrough for Chinese robot brands.
