In recent years, the development of the new economy represented by my artificial intelligence robots has been in continuous improvement, but the industry has been facing the situation of “applauding but not popular”. The COVID-19 epidemic lets us see the potential of robot in the post-epidemic era. However, the robotics industry still relies on our breakthroughs in research and development of some key core technologies, the increase in the localization rate of key core components, the reduction of costs, and the rapid iterative update of some algorithms and model functions.
In the post-epidemic era, many companies are thinking about how to reduce costs and increase efficiency. At the same time, the labor force is aging and wage costs are rising. It is difficult for factories to continue to optimize production costs. However, intelligent robot can improve the labor efficiency of workers, and big data analysis to assist decision-making can improve the efficiency of input-output ratio. Therefore, artificial intelligence has become the key to opening a new stage of manufacturing cost optimization. In the post-epidemic era, how can robot gear parts manufacturers meet the needs of downstream customers and seize development opportunities for this round?
Shenzhen ZHAOWEI Machinery & Electronics Co., Ltd (hereinafter referred to as “ZHAOWEI”) unites robot manufacturers to empower new engines for robot in terms of micro-transmission systems and joint components. Through the analysis of the robot joint structure and the design test of the motion principle, the structure of the robot joint motor has been optimized so that the robot joint servo motor has better flexibility, large torque and small size, which enables better movement in a small space. ZHAOWEI combines market demand with product R&D to continuously meet the differentiated needs of customers towards robotics.
The motor is a key link in the intelligent robot industry chain, and the robot joint is one of the components applied on the robot arm. With the widespread application of robot joints, the robot arm urgently needs to be upgraded, which also puts forward higher requirements on the motor. The existing robot arm motors generally have the problems of various specifications, small batches, poor parts versatility, high cost, and unstable quality and reliability. The range of tasks that a robot arm can complete is limited by its own mechanical structure. Using gear dc motor for robot to optimize the structure of the robot arm is one of the key technologies to solve this problem.
ZHAOWEI, together with the robot manufacturers, optimizes the structure of robot arm joint motor. Through the development of abrasion-resistant material technology, processing technology optimization, lubrication technology, assembly technology, reliability and life testing technology and the exploration of transmission mechanism, ZHAOWEI tries to develop a high efficiency and low-weight reducer (gearbox) suitable for the application of the robot arm. It has the characteristics of long life, stable work, high precision, etc., and avoids the abrasion and winding problems of the robot arm control cable, and better meets the flexible transmission requirements of robots, and greatly improves the performance of intelligent robots in perception and recognition, mechanism and transmission, control and interaction.
The International Federation of Robotics (IFR) points out, “2017 sales of industrial robots increased by 30 percent year on year to 381,335 units, the fifth year of record growth.” About Asia, it remains the world’s strongest growth market for industrial robot overall. According to the report, about 137,900 industrial robots were sold to China in 2017, 59 percent more than in 2016. This was considerably more than the combined total sales volume of Europe and the Americas (112,400 units).
At present, the market’s demand for robots is maintaining rapid growth, driving the new demand for robot joint reducers to increase rapidly at a compound annual growth rate of nearly 20%. It is estimated that the global market sales of precision reducers will exceed 60 billion yuan by 2025.
Robot joint motor is one of the core components of the robot, and downstream system integration is the key to the commercialization and large-scale popularization of robots. At present, there are few robot reducer manufacturers with large-scale production capacity and reliable product performance in the world, and most of the global market share has been occupied by Japanese companies. Although the Chinese robot motor is cheap and the delivery period is short, there is a big gap of the product performance between China and other countries. Therefore, most Chinese reducers can only be used for middle and low-end robots, and cannot meet the needs of the high-end robot market. Under this circumstances, ZHAOWEI robot servo motor engages with the big gear on the output shaft through the small gear on the input shaft, so as to reduce the speed and increase the torque to improve the dynamic performance.
For the robotics industry, the network in the 4G era cannot fully meet the needs of robots for large amounts of data calling and processing. However, with the rapid development of 5G technology, wireless high-speed data transmission has become possible. Low latency and high bandwidth mobile network enables us to use cloud technology in the field of robotics. Through continuous training and evolution of cloud brain artificial intelligence algorithms, the intelligence of the robot can be rapidly improved, making it more adaptable and expandable. The robot connects to the cloud brain through 5G network to acquires general intelligence, find the best way to perform tasks and navigation, which avoids repeated development, and saves a lot of labor work and material resources, and reduces the development cycle. The dawn of manufacturing intelligence is emerging, and artificial intelligence technology competition is in the ascendant. Companies must think about how to “light up” industrial artificial intelligence in order to gain a first-mover advantage in this race that is exclusively a “light chaser”.
