China's industrial robot three core parts gap with developed countries .
The global cost of industrial robots, about 35% is reducer, 20% is the servo motor, around 15% is the controller, mechanical processing accounts for only about 15% of ontology, the other part is mainly the application.
1: since 2013, our country has become the world's largest consumer robots, three consecutive years ranks of their industrial robot market in the world; At the same time, domestic production of industrial robot also presents the explosive growth trend, domestic industrial robot production has reached 72400 units in 2016, and the data in 2013 was only about 9000 units! But the fact is China's domestic market share accounted for only about 30% of robots, and mainly in the low-end, heavily dependent on imported high-end robot; Reducer, servo motor, controller and other key parts most dependent on imports, with core parts procurement cost was higher than that of foreign robot sales as a whole
Price.
Data 2: at present, the country has built and under construction robot industry park for more than 40, the number of robots enterprises more than 800. But the fact is that more than 800 enterprises, nearly half of the enterprise is not empty brand products, the remaining half of the nearly 70% to 80% in the enterprise is in the agent of other people's products, robot can actually produce parts or products only 100 or so. Strong contrast is ever-present reminds us that the core technology and key parts is a large gap with the developed countries. Below let small make up for everybody, industrial robots in China under the three core parts gap with the developed country, so as to ', otherwise the problem sooner or later will be "made in China" go global"
The heel "of ryukyu,!
1, speed reducer,
As technical barriers to the highest industrial robot key components - reducer according to different structures can be divided into five categories: harmonic gear reducer, cycloid pin gear planetary reduction
Speed, precision planetary reducer, RV reducer and filtering gear reducer. Among them, the RV reducer and harmonic gear reducer is the most mainstream precision reduction of industrial robots
, the RV reducer in advanced robot transmission has a tendency to gradually replace the harmonic reducer. At present, 75% of the world's precision reducer market is Japan's hammer naco
And bot, occupation, which was g production RV reducer, accounts for about 60% of the share, hammer naco production harmonic reducer, accounts for about 15% of the share.
Although in recent years, domestic also have qinchuan machine tool co., LTD., nantong vibration kang welding machinery co., LTD., wuhan essence deceleration machine manufacturing co., LTD
Companies such as production of RV reducer, but in the torsional stiffness and transmission accuracy and stability and precision index gap is obvious, resistance to fatigue strength of the gap
Obvious, easy to wear scrap, so few domestic enterprises choose robots, common also imports; Compared with the RV reducer, domestic gap harmonic reducer
Is relatively small. Although with Japanese products in the input speed, the transmission accuracy, there is a big difference between transmission efficiency and so on, but the domestic existing alternative products, such as Beijing
Harmonic drive technology research institute, Beijing or kazumi harmonic drive co., LTD, suzhou green harmonic drive technology co., LTD., etc. Products.
2, servo motor,
Servo motor is a kind of subsidy motor indirect variable speed device, can make the control speed, position accuracy is very accurate, can convert voltage signal into torque and rotational speed to drive
Motion control object, the equivalent of "nervous system" of the industrial robot. The top three domestic servo motor market, panasonic, mitsubishi, yaskawa are Japanese brand, always
Share reached 45%, doors, Bosch, schneider and other European brands to occupy the high-end, the overall market share of around 30%, domestic enterprises overall share less than 10%.
Servo motor's capacity for independent supporting have take shape in our country, many within 22 kw power range products, close to the department of technical route on Japanese products, large-scale servo
Brand has more than 20, mainly Estun Automation Co., Ltd, guangzhou nc equipment Co., Ltd., Shenzhen Inovance Technology Co., Ltd, etc.
3, the controller,
Controller is the "brain" of the industrial robot, the release and transfer instructions, including hardware and software of two parts: hardware is industrial control boards, including some
Main control unit, signal processing circuit, such as; Software is mainly control algorithm, secondary development, etc., but because of its position and the threshold is relatively low, mature factory robots
Traders generally developed controller to ensure system stability and maintenance technology. Domestic controller in the market, fanuc, yaskawa, ABB, with nearly 40% of the share,
Second line companies such as epson, OTC, staubli occupies 44% market share.
Controller with foreign gap is smaller in our country, have hardware, software domestic brands such as stability, response speed, ease of use and gap. wuhan
Huazhong numerical control Co., Ltd., Siasun Robot&Automation Co., Ltd, Shanghai STEP Electric Corporation and other related products has been achieved
The international advanced level.
At present, our country is on the transition from "industrial" to "industrial power" on the way, increase the rate of industrial robot localization and technical level is "made in China
2025 "to realize the important link, only the face defects, targeted complement, to avoid the tragedy of the spoil things by excessive enthusiasm
