In 2022, the work report of Guangzhou Municipal Government put forward for the first time that "industry comes first, and manufacturing industry establishes the market". As the key supporting equipment of advanced manufacturing industry, R&D and industrial application of robots are important symbols to measure a country's scientific and technological innovation and the development level of high-end manufacturing industry. Not long ago, 15 national robot industry authorities, regulatory authorities and application departments officially released the Tenth Five-Year Plan for the Development of Robot Industry, proposing that by 2025, China will become the global robot technology innovation source, high-end manufacturing gathering place and a new highland for integrated application.
Recently, the reporter visited a number of Guangzhou robot companies and learned that the research and development level of domestic robots has made significant progress, but the demand for professional and technical talents and high-end R&D talents is still urgent. Experts say that robots are the "carriers" of science and technology, and the development of the robot industry needs continuous research and development and support.
Guangzhou cnc:
Lay a solid research and development foundation for years of layout
In the workshop of guangzhou cnc Equipment Co., Ltd. in Huangpu District, workers are processing parts of industrial robots. When all the parts are assembled, a brand-new industrial robot is presented to the reporter.
In the field of industrial robots, there is a saying that "the north is loose and the south is vast", and the "Jianghu status" of "guangzhou cnc" in the field of robots can be seen. "guangzhou cnc is one of the domestic' four small families' relative to the four major imported families." Song Jian, general manager of guangzhou cnc Robotics Division, said that guangzhou cnc has always been in the "first echelon" in the field of domestic industrial robots.
"From 2006 to 2007, our company took the lead in setting up robot development." Song Jian said, because guangzhou cnc's research field has been dominated by numerical control system, which is related to motion control, and the company successfully studied servo drive in 1998, and completed the servo motor in 2002, which laid a very solid foundation for the research of industrial robots.
After 2008, the overall labor cost has risen, the requirements of environmental protection have improved, and people's expectations for the robot industry have become higher and higher. By 20 10, capital began to favor the emerging industry of robots, which further accelerated the development of industrial robots.
Song Jian said: "After many years, the overall reliability, function and performance of the robot have improved significantly."

Highlight: RB500 robot breaks foreign monopoly
Guangzhou cnc RB series industrial robot is a six-joint industrial robot independently developed by guangzhou cnc, which combines the important achievements of the National 863 Science and Technology Program, and its technology has been continuously improved and upgraded, and now it has formed several specifications and models.
RB series industrial robots can realize accurate and efficient handling, loading and unloading, and the movement of each joint is realized by servo motors and precision reducers with high rigidity and low backlash. Each servo motor is equipped with power-off brake, advanced electric control cabinet and teaching box, which makes it move faster, more accurately, safer and more powerful.
Among them, guangzhou cnc RB500 robot has broken the long-term monopoly of foreign heavy industrial robots, with superior performance and high technical autonomy, and is suitable for handling large workpieces, spot welding and friction stir welding. RB500 heavy-duty robot has a load of 500 kg. According to different requirements of customers, one or hundreds of robots can be used independently or cooperatively.
In addition, guangzhou cnc RH06A2 welding hollow robot, all parts of which are independently developed by guangzhou cnc, is suitable for welding fields such as automobiles and parts, motorcycle parts, electric vehicles, household appliances and hardware.

R&D investment accounts for 15% of income.
90% parts can be localized.
"Except the reducer is purchased, the other parts are produced by ourselves." Song Jian told reporters that some media mentioned that "individual robot manufacturers can achieve 90% localization", and guangzhou cnc is the representative of these "individual manufacturers".
He admits that there is still a certain gap between domestic robots and foreign robots in terms of accuracy, comprehensiveness and sales volume. "People have been making products for decades, and it is still difficult for us to catch up in just a few years or even longer, especially for products with high technical integration like robots. But it also reflects that we still have a lot of work to do. "
In recent years, the domestic robot industry has flourished, on the one hand, because the price has certain advantages, on the other hand, the imported products of foreign robots are also constantly reducing prices. "Once foreign robots have a certain substitution, many domestic manufacturers will still choose domestic robots with more affordable prices." Song Jian introduced that buying an imported industrial robot was close to 200,000 yuan at the beginning of 2 1 00,000 yuan, and now it has dropped to100,000 yuan, and the decline is still obvious.
In terms of investment, he said that the overall investment of robot enterprises is relatively large, regardless of the investment and sustainability of R&D personnel, processing equipment, testing equipment and R&D team. "This is why many companies are easy to enter, but many companies will quit later because the investment in continuous research and development is very large." For example, last year, the revenue of CNC was about 2 billion yuan, and the expenses invested by enterprises in R&D accounted for about 15% of the revenue, which was about 300 million yuan.
Guangzhou cnc supports the training of corresponding operators and skilled workers.
Personnel training needs to establish a unified training standard.
At the gate of guangzhou cnc, there is a plaque of "Guangzhou Guangshu Vocational Training College", which is still one of the urgent problems for enterprises to cultivate robot talents. Song Jian introduced that in addition to providing products, the college will also train corresponding operators and skilled workers. He said that as far as the current technology is concerned, the enterprises that can truly achieve "unmanned factories" and "black light factories" are still very limited, and the requirements for funds are also very high, so it is still very important to cultivate technical operation talents.
Song Jian said that there is no uniform and effective standard for the training of robot professionals. For personnel training, hardware equipment is actually needed, and the training period is longer. "For the practical skills training of robots, the cost is very high because there are consumables. But if employees really want to learn something well, they should be given more opportunities to do it. "
Song Jian said that large enterprises often have relatively perfect training institutions. "This requires joint training between enterprises like us and vocational colleges or small and medium-sized enterprises." Therefore, he suggested that a unified training standard should be established in the training of professionals.
Ruisong Technology:
The robot welding production line of thousands of welding points is completed in 60 seconds.
In fact, thanks to the development of scientific and technological innovation, many stereotypes left by traditional industries no longer exist, and the production scene of workers engaged in high-intensity and intensive work is gradually disappearing. Many traditional manufacturing industries have achieved automation and intelligent transformation and upgrading.
At present, automobile and 3C electronics manufacturing are the two fields that use industrial robots the most. Zhang Dongsheng, assistant to the president and director of the marketing center of Ruisong Intelligent Technology Co., Ltd., gave an example to the reporter. For example, to make a passenger car and weld the stamping parts into a complete white body, thousands of welding points need to be completed, while the robot flexible intelligent welding production line can complete the welding of the whole white body in less than 60 seconds.
He further explained that this work efficiency is that the whole intelligent production line works synchronously and cooperatively, and all robots work at the same time, which is the "heavy responsibility" of welding a car.
"In addition to automobile manufacturing, industrial robot welding will also be used in construction machinery, 3C electronics, aerospace, rail transit, marine engineering, ships, etc." He introduced that the intelligent welding equipment and intelligent manufacturing production line provided by Ruisong Technology participated in major projects such as Guang Zhouta, Humen Bridge, Baiyun Airport, Daya Bay Nuclear Power Station and Hong Kong-Zhuhai-Macao Bridge.
Ruisong Technology was officially listed on the Science and Technology Innovation Board in February 2020. Zhang Dongsheng said that listing has a great impact on the enterprise itself, and enterprises have more sources of funds, which will not only have advantages in the competition in the same industry, but also attract more high-end talents to gather, greatly enhancing the technological research and development strength of enterprises.
Automatic production line of elevator door panel developed by Ruisong Technology
Highlights:
54 seconds to load a car with four doors and two lids.
Production of 8 models of * * * production line.
Guangzhou Automobile Ruisong Technology provided the first flexible intelligent automobile door assembly line in China to Nanjing Factory of Changan Mazda Automobile Co., Ltd., and realized the random mixed-flow production of eight models. The whole line reached 54 seconds to complete the intelligent assembly of one car, four doors and two covers. It is difficult for ordinary people to drive at high speed under extreme load, but robots can be realized with the help of technology.
Ruisong Technology applies the self-developed ultra-high-speed transmission technology to the car body door cover assembly and adjustment line, adopts the reciprocating conveying device, through the lifting of the middle part of the car body and the lifting of the doorsill on both sides, and assists the motion control unit with multi-servo drive, so that the assembly and adjustment line can realize high-speed and accurate transportation, creating a record of 4 seconds 18 car body-in-white cross-project transportation, and the whole line can complete one car and four doors.
In addition, the assembly line adopts more than 230 sets of flexible numerical control positioning systems, which can seamlessly connect the positioning and grabbing of the chassis and door cover of various models, realize full-automatic and arbitrary switching, meet the production requirements of eight randomly mixed * * * lines, and achieve maximum production efficiency in the minimum space.
The flexible mixed-model production of eight types of vehicles is a great challenge to the assembly line. The mass production of door cover area needs one-to-one accurate matching with assembly line mixed production. In the project, through nearly 100 logic programs in each warehouse, with the help of vehicle identification and vehicle information transmission in MES system, each door is delivered to the assembly line after intelligent automatic matching, and the intelligent system is truly realized.
In unmanned intelligent manufacturing, machine vision is the biggest weapon to ensure the quality of production. It is understood that the assembly line * * * contains four sets of vision systems, and the 3D laser vision accuracy is as high as 0.1mm. Through the accurate comparison and calculation of the measured images, the visual guidance technology sends the deviation value to the robot controller, automatically corrects and compensates the robot's motion trajectory, guides the robot to the accurate actual working position, and realizes the accurate grasping and accurate positioning of the mounting holes of the car body, the door and the door hinge, thus realizing the accurate measurement and assembly of the car body door frame.
Guangzhou Ruisong Technology developed and designed the first flexible intelligent door assembly adjustment line in China.
High-quality talents should pay more attention to the industrial field
Today, China's economy has shifted from a high-speed growth stage to a high-quality development stage. In the past development, many talents have gathered in the commercial economy field, but there is a relative shortage of talents in the industrial field. Zhang Dongsheng told reporters, "As far as robot and intelligent manufacturing system solution providers are concerned, there are widespread problems of weak bargaining power and low gross profit level for upstream and downstream, so the investment in technology research and development and the introduction of core technical talents are restricted to a certain extent."
Industry is undoubtedly the core of a country's real economy and the most important embodiment of national strength. Revitalizing industry needs the help and wisdom of talents. Zhang Dongsheng said: "Robot and intelligent manufacturing system solution providers have the characteristics of capital-intensive, technology-intensive and talent-intensive industrial development. It is necessary not only to continuously cultivate innovative technology research and development talents, but also to cultivate and export technology application talents for industrial robot applications. Therefore, the technical talent gap in this industry is very large. "
He said that the flexible manufacturing system of smart factories in automobile factories tests the response speed to production lines and supply chains. In this process, we need not only R&D designers who are familiar with the car-making process in the early stage, but also applied talents who know about collaborative manufacturing equipment and production line scenes, and technical talents who can control robots in the later stage. All innovation and development are inseparable from the accumulation of talents.

Looking for the optimal technical strategic decision of enterprises
Regarding the choice of independent research and development or technology introduction, Zhang Dongsheng said: "I think enterprises need to find a balance between the two, and the most fundamental thing is to find the optimal technical strategic decision of enterprises."
He said that in the field of industrial robots and intelligent manufacturing, technological progress can be achieved through technology introduction, which can not only save some costs, but also shorten the technological gap with the international community in a short time and realize the rapid improvement of the enterprise's own technological level. However, technology introduction can not be limited to introduction, but also digested and absorbed, and quickly transformed into independent core technologies and products. Only by truly realizing independent research and development and independent substitution can we form an absolute advantage in technological competition and have the opportunity to achieve technological catch-up. "These two ways of technological progress are complementary," Zhang Dongsheng said.
