“China’s control systems and servo motors in the three key components of robots have been implemented from scratch. But from the best to the high-end market, China needs to increase its efforts in improving downstream applications, namely system integration. To this end, some companies in the future may increase their downstream market share in mergers and acquisitions. This is the information that the reporter obtained from the "2016 Changzhou·Yangtze River Delta Summit and High-tech Robot Industry Fair" held recently.
From 2013 to the present, China has continuously won the world's largest industrial robot market, and Chinese companies have also added robots to R&D and manufacturing.
In the robot industry, the core components include controllers, servo drives + motors, and reducers, which account for more than 70% of the cost of robots.
Among them, regarding the controller, the controller developed by the domestic enterprise can meet the basic functional requirements, and the controllers of many robot listed companies have achieved self-sufficiency. The company's market share in PC-based controllers, which is one of the industrial control electronics, is close to 50%.
The domestic brand servo system has developed very rapidly. However, in terms of technology and performance, product quality and stability, there is still a big gap with foreign brands.
In terms of reducers, the most mainstream product is the RV reducer, and Chinese companies have yet to make breakthroughs. From an international perspective, the world's four major industrial robot giant reducers are imported from Nabtesco, Japan.
"The competition between Chinese and foreign robot companies is mainly in the coordination of controllers, servo motor performance and parts." Experts say that technology does not affect economics.
In the robot, the controller is equivalent to the brain, the servo drive is equivalent to the spinal motor, the servo motor is equivalent to the muscle, and the reducer is equivalent to the joint. The performance of any of the above components affects the overall function.
"There are still some breakthroughs in the technical bottlenecks of Chinese controllers and servo motors. This has caused Chinese robots to be unsatisfactory, unable to stop, and have a short life span. It is difficult to enter the mid-to-high-end market such as automobile manufacturing." One of the four major robot giants Therefore, it has also led to fierce competition in Chinese low-end markets, and economic benefits are difficult to release.
Shen Gang, executive vice president of Shanghai FANUC Robotics Co., Ltd., said that Chinese robotics companies have not paid enough attention to the downstream market share, and they are somewhat biased in the direction of component product development. Chinese companies should first expand the downstream system integration market for robots, and then do upstream parts development to improve localization. Zhang Wei, vice president of Eft Intelligent Equipment Co., Ltd., agrees with Shen Gang that the robotic downstream system integration market is very broad.
KNB1-100 Miniature Circuit Breaker
KNB1-100 Mini Circuit breakers, also named as the air switch which have a short for arc extinguishing device. It is a switch role, and also is a automatic protection of low-voltage electrical distribution. Its role is equivalent to the combination of switch. Fuse. Thermal Relay and other electrical components. It mainly used for short circuit and overload protection. Generally, According to the poles, mini Circuit breaker can be divided into 1P , 1P+N , 2P, 3P and 4P.
