Where is the core competitiveness in the field of robot lubrication?
Robots are known as the pearl at the top of the manufacturing crown. Due to various factors such as rising labor costs, production efficiency, and quality improvement, the global industrial robot industry has grown rapidly in recent years. The world's leading manufacturing nations have realized that only by mastering robotics technology can they seize high-end intelligent manufacturing. Commanding heights. According to the International Federation of Robotics (IFR), by 2020, 520,000 new industrial robots will be applied to factories around the world, of which more than 40% will be in the Chinese market, and China has become the world's largest consumer of industrial robots. However, compared with the international advanced level, the robot industry in China still has a big gap, especially in some professional fields, such as the field of robot lubrication.
Industrial robots, as a special type of industrial machinery and equipment, need professional lubrication to assist them. The performance, economics, and service life of grease are different under different working environments, so the requirements for grease are different. At present, robots usually use grease to lubricate, and the use of lubricating oil is becoming less and less. The main reason is that once the seal of the robot reducer ages, the oil will leak, and the grease has low requirements on the seal, and it is not easy to leak. In general, the threshold for robot lubrication does not come from technology, but from the development and production of upstream reducers, which are mainly concentrated on RV reducers.
Current development status of reducers at home and abroad
The work of industrial robots is delicate and complicated, and has high requirements for the quality of lubrication. A reducer is one of the core components of a robot. Each joint of the robot needs a reducer to support every movement. Ensuring smooth operation of the reducer is the key to the normal operation of the robot. Lubricating oil or grease is like joint fluid to protect the joints of the human body, ensuring the smooth operation of the reducer.
Reducers can be divided into RV reducers and harmonic reducers. The RV reducer is generally used in the RV reducer that is not mature in China. The current RV reducer field is basically monopolized by Japan. The cost of a reducer in foreign countries is about 20,000 to 50,000. The cost of importing such products is 70,000 to 120,000, which greatly increases the cost of industrial robot research and development; domestic harmonic reducers have developed rapidly in recent years, and there is not much difference compared with foreign countries. In the future, domestic oil manufacturers will be here. There will be better development opportunities in one area.
Compared with foreign countries, what is the gap in the field of domestic robot lubrication?
Among the core components of industrial robots, precision reducers are the most critical. In the global market, Japanese companies have a monopoly of 75% of the market share. The gap in some domestic lubrication fields is still reflected in the gap between humans and processes, subject to equipment manufacturing. Even though the field of lubrication has been done well in China, it still supplies imported equipment in the market, just as there are currently manufacturers of RV reducers in China, but regardless of the precision, tolerance tolerance, materials and Compared with the Japanese RV reducer, the heat treatment after the material processing is still a large gap. The gap between reducers is mainly concentrated on the precision of the equipment, and the precision of the equipment is closely related to the processing machine, so the level of technology and technicians will affect the precision of the equipment. For robot lubrication, there is not much difference between domestic and foreign.
Market ties to domestic oils
The RV reducer is relatively expensive to manufacture, and the grease is a consumable and consumable part of the equipment. Most OEMs will comply with the requirements of the reducer supplier and specify the grease. Although the price is slightly higher, the risks and benefits are compared, and the risk of replacing grease It seems to be higher, so there are very few cases of changing the oil brand. Domestic oils are still facing obstacles when they want to exert their power on the robot. In this way, Japanese brands control the core component-reducer equipment manufacturing by virtue of refined production. It has controlled the coordinated supply of its upstream and downstream industries.
How to break through in the field of domestic robot lubrication?
At present, from the reduction gear, servo motor, controller, body to the production and processing of various auxiliary materials, China has initially formed a complete intelligent equipment industry chain. But if you want to make a breakthrough in the field of robot lubrication, there are several directions you can refer to: First, strengthen self-service research and development and deep cooperation with well-known robot manufacturers at home and abroad, mainly to learn more experience at the level of refined manufacturing Secondly, relying on the development and growth of domestic machinery manufacturing brands, the market share is continuously increased by expanding the scope of services for manufacturing enterprises.
In the future, the transformation and upgrading of China's manufacturing industry will require more intelligent manufacturing equipment. While we affirm technology research and development capabilities, we should also see the gap with advanced foreign levels. Only in the field of intelligent manufacturing, we will continuously improve our market competitiveness and strengthen equipment In order to help China's intelligent manufacturing industry take off, the refined production of it can help.
