According to the relevant statistics of the National Bureau of Statistics, China’s industrial robots increased by 33.7% in the first five months of 2018. It can be seen that the proportion of industrial robots in industrial production is constantly increasing, and the market demand is increasing year by year. In the future, the replacement of labor by industrial robots becomes an irreversible trend.
As a cable and connector manufacturer that provides internal connections to robots, it is natural not to miss this promising sunrise area. At the same time, industrial robots are undergoing continuous iterative upgrades of technology, which will inevitably bring about tremendous changes in the field of wiring and connectors, which will bring revolutionary prospects for the entire connected device.
Industrial robots flourish
The turning point of the demographic dividend is coming, and the rise of the “machine substitution” wave has led to a large number of companies entering the robotics industry. Among them, the Chinese market is very eye-catching. By 2018, China has become the largest consumer of industrial robots for five consecutive years.
According to the prediction of IFR of the International Robot Industry Association, the sales volume of China’s robot industry is expected to maintain a growth rate of 25%-30% in the next few years. In 2018, the sales volume of China’s industrial robot market is expected to exceed 150,000 units, which will continue to be the strongest growth in the global market. Driving force. In 2020, the sales volume of working robots in China is expected to reach 270,000 units.
Industrial robots appeared in the 1960s. After decades of development, they have been continuously updated and developed at a faster rate. This is due to the development of technology and the demand of the industrial production market. Industrial robots are gradually moving from simplification to complex multi-functionality. At present, the replacement of labor by machines has become a trend, and I believe that industrial robots will flourish.
As far as China’s current economic development is concerned, the changes in population structure and the increasing labor costs have led many companies to introduce industrial robots for industrial production and processing. Firstly, it can improve the efficiency of production and guarantee the quality; secondly, it can reduce the production cost and has obvious advantages in the competition; in addition, it is easier to manage and more suitable for future production. Therefore, the demand for industrial robots in China will become larger and larger.
However, China’s robotic products are intensive in the low-end sector, and the overall competitiveness is not strong. In the market, local companies basically rely on low prices to maintain their own advantages. At the same time, the international four major families are well-positioned in the Chinese market, and the competitive pressure faced by domestic robot companies is also great. At the same time, the robot body faces the risk of price cuts, and the market competition is more intense.
According to the preliminary statistics of the Ministry of Industry and Information Technology, there are more than 800 enterprises involved in the production of robots in China, of which more than 200 are robotic body manufacturing enterprises, most of which are mainly assembled and processed, at the low end of the industrial chain, and the industrial concentration is very low. The overall size is small. According to the Japan Robotics Industry Association, orders for industrial robots in Japan increased by 27.8% in 2017 to reach 944.7 billion yen.
However, in order to change this situation, China’s “Made in China 2025” strategy clearly proposes the development plan of CNC machine tools and robots.
Cable/connector demand is rising
It is understood that by 2020, more than half of the world’s new industrial robots will be installed in China, and robots made in China will also occupy a considerable proportion. As a component for robots, the development of robotic cables and connectors is required. Space should not be underestimated. The industrial robot industry is booming in China and is attracting more and more interest from cable and connector companies.
Wire and cable as an important part of the robot, the market demand has exploded, wire and cable companies will usher in rare development and transformation opportunities.
The arrival of Industry 4.0 and industrial automation means that more intelligent equipment and robots will be widely used in various production fields, and their demand shows a steady and rapid growth trend. Among them, the core intelligent equipment and robots have high requirements for connectors, and more “high-precision, high-performance” connectors will be more and more applied to these intelligent equipment and robots.
In general, cable and connector companies that are currently entering the field of industrial robots are mainly foreign-owned, but domestic companies have already targeted this market.
Driven by factors such as the growth of downstream robot shipments, the widening of global supply gaps in cable connectors, and the maturity of domestically produced technologies, domestic cable connector companies are welcoming rare opportunities for development.
However, it is understood that more than 80% of China’s current robot market uses imported cables and connectors. In this market, foreign companies are far ahead. For example, FooConn has invested a large amount of funds in research and development, and its products have been applied to servo drives such as Mitsubishi, Yaskawa, Panasonic, Delta, Sanyo, Omron, Eston, Huazhong CNC, and Guangzhou CNC.
To this end, He Jiancheng said: “China has a very good innate condition, that is, our market is big. China will have a great demand in the development of industrial robots, so the development of localization of connectors is an urgent task. As far as I know, there are quite a few connector companies in China that have invested in the development of industrial robot connectors.”
There is also great potential in import substitution, but it is still too early. In addition to the price and longevity of domestically produced cables and connectors, there are still problems with the product series being unsound and consistent. The performance of some products in the actual use environment does not match the laboratory performance, hindering the localization process.
Domestic industrial connectors still have a long way to go. In the short term, domestic industrial robot connectors are still quite inferior. The latest technology is controlled by foreign companies and is largely restricted by foreign companies. In the long run, we must seek independent development, increase research and development efforts, and keep up with the trend. To treat it as a long-term project, in order to break the current stalemate of high-end connectors being monopolized by foreign countries.
High technical difficulty, long investment cycle
Although cables and connectors are just a small part of the intelligent control process, this is the foundation for ensuring overall quality and intelligence. Cables and connectors are an indispensable part of industrial robots, and their future development has become the focus of attention.
As a carrier and an important component for transmitting power and control capabilities, robotic cables are especially important for robots. The robot cable is like a central system to humans. If there is a problem with any loop, the whole system will not function properly. Due to the often harsh environment, robot cables must have a range of special features.
Industrial connectors have strict requirements for reliability, IP rating, operating temperature and shock resistance, and even many indicators require automotive and even military standards. As a result, the original factory needs a longer cycle in the development of new products, more considerations and more stringent tests, and higher research and development costs, which greatly test the comprehensive strength of the manufacturers.
The reliability of domestic industrial robot connectors needs to be improved, and efforts should be made to develop new technologies for industrial robots. At present, high-end industrial robot connectors are monopolized by a few large foreign companies. The threshold is high and the investment is very large. It requires strong financial support and talent introduction. Many domestic enterprises have also entered the research and development of industrial robot connectors. Due to the long period of investment in this field, no good benefits have been produced yet.
Cables and connectors are an important part of industrial robots, and their development has a great impact on industrial robots. Traditional industrial robots have been unable to meet the requirements of industrial manufacturing development. At present, customers have put forward comprehensive requirements such as “wireless, customized and flexible” in the field of industrial robot connection.
Industry 4.0 replaces traditional wired fieldbus technology, and this change is driving a major disruptive change need, the wireless interconnect system.
In many operating environments, it is not possible to connect the robot and only transmit signals to the robot via a wireless connection. Obviously, compared with the traditional connection method, the development of industrial robots will inevitably bring about tremendous changes in the connector field, and this new development will also feed back other areas of connectors, which will revolutionize the entire connected device. Progress prospects.
The rapid growth of the Internet of Things (IoT) has driven the widespread demand for networked sensor arrays that need to communicate over a wireless mesh network to monitor many factors in the production environment, such as temperature, humidity, lighting, asset tracking, and assets. Management, etc.
It can be seen that the improvement of the demand for wireless interconnection technology by Industry 4.0 has brought new opportunities to connector manufacturers. In recent years, manufacturers such as TE and MOLEX have also begun to expand the direction of product design from “wired” to “wireless”.
In addition to the expanding needs of “wireless” technology, product “customization” is particularly important in the industrial sector. Industry insiders know that traditional connectors and cables are mostly passive products, and manufacturers can provide standardized products to customers.
However, with the emergence of electronic product diversification and intelligent demand, manufacturers need more “customized” products to meet customer needs, especially in the industrial field, connector manufacturers need to develop new products together with customers to meet customer uniqueness. The shape and function needed.
In recent years, the demand for “customization” of industrial connectors has become increasingly obvious. Compared with “standardized” products, “customized” products require companies to have a stronger design and development team and a wide range of connectors to facilitate rapid Assembled into a complete solution to meet market needs.
The customer’s “customized” needs will exist for a long time, especially in the new application areas such as automotive electronics, Internet of Things, smart homes, etc., and require new solutions. Working closely with our partners, we are able to meet the “unique” requirements of our customers while maintaining a high level of product quality. This is the job of the connector supplier.
In addition, industrial automation has also proposed “flexibility” requirements.
With the development of intelligence and digitalization, the demand for innovation in industrial connection is becoming more and more stringent. For example, in the realization of system flexibility, a large number of plug-in cables and interface methods need to be turned into a non-contact flexible mode.
The cable not only has heat resistance and flame retardancy, but also has excellent bending resistance and flexibility to meet the requirements of the movable portion of the industrial robot that can withstand repeated bending and twisting.
