Manufacturing is established as a city
In 2022, the work report of the Guangzhou Municipal Government for the first time proposed to "adhere to the industry first, manufacturing industry city". As a key supporting equipment for advanced manufacturing, robots' research and development and industrialization applications are an important symbol of a country's scientific and technological innovation and high-end manufacturing development level. Not long ago, the 15 national robot industry authorities, regulatory departments and application departments officially issued the "14th Five-Year" Robot Industry Development Plan, proposing that by 2025, the mainland will become the source of global robot technology innovation, high-end manufacturing agglomeration and a new highland for integrated applications.
Recently, the reporter visited a number of Guangzhou robot companies to investigate and learned that the research and development level of domestic robots has made significant progress, but the current demand for vocational and technical talents and high-end research and development talents is still urgent. Experts said that robots as the presentation of science and technology "carrier", the development of the robot industry needs continuous research and development and support.
Guangzhou CNC:
Years of layout laid a solid foundation for research and development
In the factory building of Guangzhou CNC Equipment Co., Ltd. (hereinafter referred to as "Guangzhou CNC") in Huangpu District, workers are processing parts of industrial robots, and when all the parts are assembled, a new industrial robot is presented to the reporter.
In the field of industrial robots, it is known as "North Siasong, South Guangzhou", and the "jianghu status" of "Guangzhou CNC" in the field of robotics can be seen. "Compared with the four major imported families, the domestic 'four small families', Guangzhou CNC is also one of them." Song Jian, general manager of Guangzhou CNC Robot Division, introduced that Guangzhou CNC has always been in the "first echelon" in the field of domestic industrial robots.
"From 2006 to 2007, we took the lead in the development of robots within the company." Song Jian said that because the research field of Guangzhou CNC has been mainly numerical control systems, related to motion control, coupled with the company's successful research on servo drive in 1998, by 2002 the study of servo motors, etc., laid a very solid foundation for the study of industrial robots.
After 2008, the overall labor cost rose, environmental protection requirements increased, and people's expectations for the robot industry became higher and higher. By 2010, capital began to favor the emerging industry of robots, which further accelerated the development of industrial robots.
Song Jian said: "After doing it for many years, there is still obvious progress in the overall reliability, function and performance of the robot. ”

Highlights: RB500 robot breaks the monopoly of foreign countries
Guangzhou CNC RB series industrial robot is a six-joint industrial robot independently developed by Guangzhou CNC, which integrates the important achievements of the national 863 science and technology plan project, and the technology is continuously improved and improved, and a number of specifications and models of products have been formed.
RB series industrial robots can achieve accurate and efficient handling and loading and unloading, the movement of each joint is achieved by a servo motor and a high-stiffness, low side gap precision reducer, each servo motor is equipped with a power loss brake, while equipped with advanced electrical control cabinet and teach box, so that its movement speed is faster, more accurate, more superior safety and more powerful.
Among them, Guangzhou CNC RB500 robot breaks the situation that heavy-duty industrial robots have been monopolized by foreign countries for a long time, with superior performance and high technical autonomy, suitable for large-scale workpiece handling, spot welding, friction stir welding, etc. The RB500 heavy-duty robot has a load of 500 kg and depending on customer requirements, one or hundreds of units can be used alone or in collaboration.
In addition, Guangzhou CNC RH06A2 welding hollow robot, also all parts for Guangzhou CNC independent research and development, suitable for automobiles and parts, motorcycles, electric vehicles, home appliances, hardware and other welding fields.

R&D investment accounts for 15% of revenue
90% of the components can be localized
"Except for the reducer, which is partially purchased, the other components are produced by ourselves." Song Jian told reporters that "individual robot manufacturers can achieve 90% localization" mentioned in the media, and Guangzhou CNC is the representative of these "individual manufacturers".
He frankly said that no matter in terms of accuracy, comprehensiveness or sales volume compared with foreign robots, there is still a certain gap between domestic robots. "People have been making products for decades, and it is still very difficult for us to catch up with them in just a few years and more than ten years, especially products with high technical difficulties such as robots." But it also reflects that we have a lot of work to do. ”
In recent years, the domestic robot industry has flourished, on the one hand, because the price has a certain advantage, on the other hand, foreign robot imports are also constantly reducing prices, "once foreign robots have a certain degree of substitution, many domestic manufacturers will still choose more affordable domestic robots." Song Jian introduced that in the early 21st century, it was close to 200,000 yuan to buy an imported industrial robot, and now it has dropped to 100,000 yuan, and the decline is still very obvious.
In terms of investment, he said that the overall investment of robot companies is relatively large, whether from the input and sustainability of R& D personnel, or processing equipment, testing equipment, and R & D teams. "That's why it's easy for a lot of companies to get in, but there are a lot of companies that exit later, because the continuous R&D investment is very large." For example, he said that last year, the revenue of Guangzhou CNC was about 2 billion yuan, and the cost of enterprise investment in research and development accounted for about 15% of the revenue, about 300 million yuan.
Guangzhou CNC supporting training of corresponding operators, technical workers.
Talent training needs to establish unified training standards
At the gate of Guangzhou CNC, there is a plaque of "Guangzhou Guangshu Vocational Training College", which is still one of the problems that enterprises urgently need to solve for the training of robot talents. Song Jian introduced that in addition to providing products, the college will also support the training of corresponding operators and skilled workers. He said that as far as the current technology is concerned, the enterprises that can really achieve "unmanned factories" and "black light factories" are still very limited, and the capital requirements are also very high, so it is still very important to cultivate technical operation talents.
Song Jian said that in the training of robot professional talents, there is no unified and effective standard at present. For talent training, it is necessary to invest in hardware equipment in a down-to-earth manner, and the training cycle is also longer. "For the practical skill development of robots, the cost is very high, because there are consumables. But to make employees really learn good things, we must give him more opportunities to do it. ”
Song Jian said that large enterprises often have relatively complete training organizations. "This requires companies like us to do a good job of joint training with vocational colleges or small and medium-sized enterprises." He therefore suggested that uniform training standards should be established in the development of professional talents.
Ruisong Technology:
Thousands of welding points Robot welding production line is completed in 60 seconds
In fact, thanks to the development of scientific and technological innovation, many of the stereotypes left to us by traditional industries are no longer there, the production scenarios of labor engaged in high-intensity and intensive work are gradually disappearing, and many traditional manufacturing industries have realized the transformation and upgrading of automation and intelligence.
At present, automotive and 3C electronics manufacturing are the two major areas that use industrial robots the most. Guangzhou Ruisong Intelligent Technology Co., Ltd. (hereinafter referred to as "Ruisong Technology") assistant president, marketing center director Zhang Dongsheng to reporters for example, such as manufacturing a passenger car, the stamping parts welded into a complete body-in-white, the need to complete thousands of welding points, robot flexible intelligent welding production line can complete the welding work of the entire body-in-white in less than 60 seconds.
He further explained that such work efficiency is the synchronization and collaborative work of the entire intelligent production line, and all robots are working at the same time to jointly complete the "heavy responsibility" of welding a car.
"In addition to the field of automobile manufacturing, industrial robot welding will be used in construction machinery, 3C electronics, aerospace, rail transit, marine engineering, and ships." He introduced that in the construction of major projects such as The Canton Tower, Humen Bridge, Baiyun Airport, Daya Bay Nuclear Power Plant, Hong Kong-Zhuhai-Macao Bridge and so on, the intelligent welding equipment and intelligent manufacturing production lines provided by Ruisong Technology have been involved in the completion.
Ruisong Technology officially landed on the Science and Technology Innovation Board in February 2020. Zhang Dongsheng said that the impact of listing on the enterprise itself is relatively large, the company's source of funds is more diversified, not only can be more advantageous in the competition in the same industry but also attract more high-end talents to gather, greatly enhance the company's technology research and development strength.

8 models produced in collinear production
The first flexible intelligent door assembly line in China provided by Guangzhou Ruisong Technology to Changan Mazda Automobile Co., Ltd. Nanjing Plant realizes the random mixed collinear production of 8 models, and the entire line reaches 54 seconds to complete the intelligent assembly of one car, four doors and two covers. Ordinary people are difficult to travel at high speeds under extreme loads, but robots can achieve with the help of technology.
Ruisong Technology will be independently developed ultra-high-speed transmission technology applied to the body door cover mounting and adjustment, the use of reciprocating circulation conveyor device, through the development of the body middle lift and two sides of the threshold lift two forms, auxiliary motion control unit in coordination with multi-servo drive, so that the assembly of the line to achieve high-speed precision transportation, to create 4 seconds to complete 18 body-in-white body engineering transport record, the whole line reached 54 seconds to complete a car four doors and two covers intelligent assembly.
In addition, the assembly line uses more than 230 sets of flexible NC positioning systems, which seamlessly docks the positioning and grasping of the body chassis and door cover of each model, realizing fully automatic arbitrary switching, meeting the random hybrid collinear production of 8 models, and achieving maximum production efficiency in the smallest space.
8 models of flexible mixed line production is a major challenge of the assembly line, the mass production of the door cover area needs to be one-to-one accurate matching with the mixed line production of the assembly line, the project through each library location of nearly 100 logic programs, with the car type identification and MES system of the car type information transmission, intelligent automatic pairing after each door will be transported to the assembly line, truly realize the intelligent system.
In unmanned intelligent manufacturing, machine vision is the biggest weapon to ensure that the quality of production meets the standard. It is understood that the assembly line contains a total of 4 sets of vision systems, and the 3D laser vision accuracy is as high as 0.1 mm. Visual guidance technology through the measurement image accurate comparison calculation, the deviation value is sent to the robot controller, automatic correction, compensation of the robot action trajectory, guide the robot to reach the accurate actual working position, so as to achieve accurate grasping, accurate positioning of the body, door, door hinge mounting hole, so as to achieve accurate measurement and assembly of the body door frame.

High-quality talents should pay more attention to the industrial sector
Today, the mainland economy has shifted from a stage of high-speed growth to a stage of high-quality development. In the past development, many talents have gathered in the commercial economy, and there is a relative shortage of talents in the industrial field. Zhang Dongsheng told reporters, "As far as robots and intelligent manufacturing system solution providers are concerned, there is currently a general problem of weak bargaining power and low gross profit level for upstream and downstream, so it is restricted to a certain extent in terms of investment in technology research and development and the introduction of core technical talents." ”
Industry is undoubtedly the core of a country's real economy, and it is also the most important embodiment of national strength. Revitalizing industry requires 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. We not only have to continuously cultivate innovative technology research and development talents, but also cultivate and output technical application talents for the application end of industrial robots, so the gap of technical talents in this industry is very large. ”
He said that the flexible manufacturing system of the intelligent factory of the automaker tests the speed of response to the production line and the supply chain. In this process, not only do you need R & D designers who are familiar with the car-making process in the early stage, you need to understand the application-oriented talents who know how to collaboratively manufacture equipment and production line scenarios, and you also need technical talents who can control robots in the later stage, etc. All innovative development is inseparable from the accumulation of talents.

Find the best technology strategic decisions for your business
For the choice of independent research and development or technology introduction, Zhang Dongsheng said: "I think enterprises need to find a balance between the two, the most fundamental is to find the best technology strategic decision of the enterprise. ”
He said that in the field of industrial robots and intelligent manufacturing, technological progress through technology introduction can not only have certain savings in costs, but also shorten the technical gap with the international community in a short period of time and achieve rapid improvement of the company's own technical level. However, the introduction of technology can not only be limited to the introduction, but also digested, 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 catch up with technology. "These two ways of technological progress are complementary." Zhang Dongsheng said.
