With the help of policy support, demand-pulling, market verification and other factors, domestically produced core components are entering the eve of an eruption! The following new controls on industrial control do not need to go into the relevant contents.
Whether it is the reduction of trust in gearboxes, the steady development of servo motors, or the fact that controllers have entered the high-end market, they all indicate that China is slow to control foreign-funded enterprises on key components such as retarders, servo motors, and controllers. Slowly changed.
Domestic manufacturers have successively overcome some of the challenges in the core component sector and are steadily advancing the localization of components. This will reduce the cost of domestic robots, increase the share of domestic robots in new installed capacity, and more importantly, it will break down. The monopoly of foreign brands in key areas.
Reducer: Trust to replace localization of accelerated ice-breaking
Since the beginning of this year, thanks to the global shortage of the reducer market, domestic reducer companies ushered in rare opportunities for development and broke orders.
On March 13, Shanghai Huanyan Automation purchased 15,000 decelerators from Nantong Zhenkang and held a grand signing ceremony.
On June 13, Polylon Transmission announced that its holding subsidiary Anhui Julong Robot Reducer Co., Ltd. recently signed the “ER20-C10 Polylon Speed ​​Reducer Purchase and Sale Contract†with Eft.
There are also a lot of domestic robot companies that have expressed their willingness to use domestic brands in certain areas where domestic reducers can be used.
In fact, in 2017, the sales volume of domestic main reducer manufacturers increased significantly and almost doubled. Nantong Zhenkang reducer shipments increased by approximately 120% from the previous year; Suzhou Green's reducer shipments increased by nearly 100% year-on-year; as the backbone of domestic reducers, Lectra Precision has exceeded 5,000 units of RV reducer shipments this year. The existing equipment capacity is 30,000 units.
At the same time as sales increase, domestic deceleration companies are also preparing for the outbreak.
It is reported that Qinchuan Machine Tool's "Digital Robotic Joint Reducer Workshop" has been delivered in early 2017. The new production line has effectively helped the traditional speed reducer products to achieve intelligent upgrades. The annual output is expected to reach 60,000 pieces.
Shuanghuan Transmission has already launched a fundraising project, of which 300 million yuan has been invested in the industrial robot RV reducer project. Two series of 14 models of robotic precision reducer have been completed on the market, and the testing has been gradually completed in small batch production. Three years after the completion of the planning, the plant will be fully operational and will achieve an annual production capacity of 60,000 RV speed reducers.
According to the GGII survey, based on the market's strong demand and its own cost considerations, many manufacturers have entered the area of ​​reducers, which also includes the robot body business.
It is understood that Guangzhou Qifan has established a precision transmission department and can independently develop and produce planetary, harmonic and RV speed reducers with a backlash more than 3 times that of laser cutting. It is reported that currently 90% of Kaifan's robots use self-developed speed reducers. In addition, there are already many robotics companies that are beginning to enter the field of reducers, such as Chuan, Wah Shing Control and Huan Yan Automation.
Servo Motors: Steadily Developing Specialization Levels
In the domestic servo motor market, the top three brands, Panasonic, Mitsubishi, and Yaskawa, are Japanese brands with a total share of 45%. European brands such as Siemens, Bosch, and Schneider mainly occupy high-end markets, with a market share of around 30%, and the overall share of domestic companies. Less than 10%. However, with the increase in the number of local and Taiwanese brand market participants and the continuous expansion of market size, the share of domestically produced companies in the industrial robot servo system market has gradually increased.
Continuing the situation of the previous two years, domestically-made brand servo motors have also achieved steady development this year, and the self-supporting capabilities of servo motors have begun to take shape, gaining certain market recognition.
Many domestic products are technically close to Japanese products, and more than 20 large-scale servo motor brands such as Huichuan Technology, Estonia, Guangzhou CNC, and Inventronic have emerged.
Thanks to the changes in the market environment, domestic equipment manufacturers have begun to take the initiative to upgrade, so there is a large demand for high-performance, relatively affordable servo products.
In the 2013 semi-annual report released by Inovance Technology, Interim Technology achieved operating revenue of 1.937 billion yuan in the first half of the year, an increase of 32.24% year-on-year, and a net profit of 429 million yuan attributable to the mother, an increase of 10.31% over the same period last year. Among them, the general-purpose servo system achieved sales revenue of 340 million yuan, a year-on-year increase of 120%, and it was one of the largest growth business segments. Invensys’ operating revenue for the first half of the year increased by 320 million yuan over the same period of last year, of which servos achieved revenue of 73 million yuan, an increase of 50% year-on-year.
As an AC servo system that is one of Essen's smart equipment core control function components, sales continue to grow rapidly. In order to further enhance the product quality of the AC servo system, Eston has started the automation and intelligent upgrade project of the intelligent production workshop of the AC servo system.
The heavy demand of 3C market also brought the demand for small robots. For the core component companies, the miniaturization of the robot means that the core components of the robot also need to be miniaturized. In this year's new servo motor products, almost all emphasize the smaller size or can be in a more narrow space The characteristics of the installation.
In addition, the dedicated servo system for robots has become a breakthrough for companies in the subdivided field. This is reflected in both the MH800 hydraulic servo system developed by Inventronics for the hydraulic industry and the EHMA series servo drive developed by Eston for the punch press.
Controller: Combining high-end hardware and software is key
After years of precipitation, the hardware platform used by domestic robot controllers is not much different from foreign products. The gap is mainly reflected in the control algorithm and ease of use of the secondary development platform. Therefore, with the rapid development of market demand, domestically-manufactured controller companies are greeted with opportunities for development.
At present, China's controller market is basically divided equally between domestic and foreign investment. With the continuous improvement of domestic technology, domestic market share is expected to increase further.
In 2017, new domestically-developed controllers were introduced frequently. What needs special emphasis is that in September, Kawasaki Robots signed a purchase contract for 1,000 controllers with the release of a self-developed controller by Zhejiang Zhichang Industry Co., Ltd.
In addition to independent research and development, there is another way for domestic robot companies to accelerate the deployment of core components. In this year's major mergers and acquisitions in the robotics industry, there were also a few cases involving core components, especially motion control, such as TRIO (TRIO) acquired by Eston and ROBOX acquired by Eft.
The control system is divided into hardware and software. The optimization based on hardware and the secondary development based on software are the key to differentiated competition. In fact, mainstream robots are self-owned control systems. With the application of robots, "software and hardware integration" has become the focus of the company.
With the trend of miniaturization of robots, the current "control and control integration" has become a hot spot for domestic companies' R&D. In this year's Senior Robot Robot Golden Globe Awards, companies including Guzheng, Zhongwei Xing, and Xichuan Science and Technology have all applied for the selection of products for driving control.
It is reported that most of the domestic control and control products still use a distributed control mode with a motion controller and multiple servo drives. In practical applications, there are still problems such as high system hardware redundancy, signal transmission interference, and high price.
In the continuous efforts of domestic companies, these problems will be broken one by one. The high-speed six-axis control and control machine that GuGao launched this year can solve the problem of system redundancy. In fact, as early as 2012, when it was doing the 863 project, Googol proposed the development direction of “invitation and control integrationâ€.
