Development status/prospects and trend forecast of China's industrial robot industry in 2021

 In recent years, the development of industrial robots has gradually received attention, the state has introduced various incentive measures, and local governments have also rushed to set development goals. The core content is to achieve independent innovation and accelerate the process of domestic substitution. At present, my country's industrial robot industry is in the preliminary industrialization stage, gradually moving from the development stage to the mature stage.

In the global market, China's installed capacity and output of industrial robots rank first in the world in 2019, but the installed density still has great potential. In the future, China's industrial robots will develop toward a more intelligent and flexible direction under the blessing of emerging technologies such as cloud computing. At the same time, the outbreak of the new crown epidemic in 2020 has enabled many manufacturers to see the development potential of industrial robots in the medical field.

Industrial robot industry overview

1. Definition

Industrial robot is a general term for robots used in industrial production. Industrial robot is a kind of automatic operation through programming or teaching. It has multiple joints or multiple degrees of freedom, and has certain perception functions, such as vision, force sense, displacement detection, etc. , So as to realize the independent judgment and decision-making of the environment and the work object, and can replace the automatic machines that manually complete all kinds of manual labor in heavy, boring or harmful environments.

The subdivision of industrial robots is usually classified according to coordinate form, driving method and motion control method. From the operating mechanism of industrial robots and the requirements for the quality of the realized functions, the joint coordinate system has high accuracy and is also the most widely used type. Electric drive is the mainstream of today's industrial robot drive, and the continuous trajectory control requirement is for high-end industrial robots. Basic Quality".

2. Analysis of the industrial chain: the industrial chain involves many links

The industrial robot industry is divided into upstream, midstream, downstream and industry applications according to the industry chain. The upstream is the production of core components such as reducers, servo systems, and control systems; the midstream is the production of industrial robots; the downstream is the integration of industrial robot systems based on the specific needs of the terminal industry, which are mainly used to achieve welding, assembly, testing, handling, spraying, etc. Process or function; industry applications are mainly the application of industrial robots to terminal industries such as automobiles and electronics that have high demands for automation and intelligence.

In the upstream field, reducers, servo motors, and controllers are the three major components of industrial robots. Large foreign industrial robot companies often build their core competitiveness by mastering key component technologies. In recent years, with the improvement of domestic technology, independent brands have gradually entered related fields. In the field of reducer manufacturing, representative companies include Green Harmonic, Shanghai Electromechanical, and Zhongda De; in the field of controller manufacturing, representative companies have green Harmonic, Shanghai Electromechanical, Zhongda De; in the field of system integration, representative companies include Estun, Inovance Technology, Lei Sai Intelligent, Kelier, etc.

In the field of midstream industrial robot body manufacturing, from the perspective of the domestic market, my country's industrial robot body manufacturing market is still dominated by foreign companies, with representative companies such as Fanuc, ABB, KUKA, and Yaskawa. Representatives of self-owned brand industrial robot body manufacturing include Siasun Robotics, Estun, Huazhong CNC, Xinshida, Yawei Co., Ltd. and so on.

In the field of downstream industrial robot system integration, representative companies include Topstar, Siasun Robotics, Kelai Electromechanical, Boshi Co., Ltd., Huachangda, Estun, etc.

China has quickly passed the automation stage by virtue of its strong population advantage. At present, there are already many domestic leading industrial robot companies that have matured in the machine intelligence stage business, such as Questyle Technology and Hikvision. Outstanding. And with the advent of an aging society, the demographic dividend is gradually dissipating, and labor costs are increasing, pushing companies to implement robot substitution measures. At present, China, like Japan, South Korea and other leading countries, is in the transitional stage from machine intelligence to artificial intelligence; China is also at the forefront of the world in terms of artificial intelligence technology accumulation.

According to the industry life cycle theory, the life development cycle of the industry mainly includes four development stages: immature, growth, maturity, and decline. The characteristics of the industry in the mature stage are: the industry growth rate drops to a more moderate level, the number of new enterprises will decrease; the industry entry barriers increase; and the influence of technological innovation factors is excluded, the development pace of the industry and the gross national product Stay in sync.

Combining with the current development of China's industrial robot industry, it can be judged that it conforms to most of the characteristics of the mature industry, so it can be judged that the industry is in the transitional stage from the growth stage to the mature stage.

Low-cost new technology can track flexible surgical robots through magnetism

Flexible robotic surgical equipment has very broad application prospects. One of the advantages is that it can move on vulnerable parts of the body without causing damage. Since these devices are usually made of soft, soft materials, they do not always show up well when using traditional imaging techniques.

In search of a better alternative, the science team at the University of California, San Diego created a new system. In this system, a magnet is installed at the front end of a flexible robotic device. When the robot moves in a closed environment (which will eventually enter the human body), four spaced external sensors measure the strength of the magnetic field generated by the magnet.

Through an artificial neural network, the system compares the readings of the four sensors and uses these data to accurately determine the position of the robot's front end. This is similar to how GPS uses multiple satellites to calculate the user's location.

So far, the system has been successfully tested in a laboratory-based model, using a nylon tube-type robotic device that grows in length as the liquid is pumped into it. According to reports, the entire device, including robots, magnets, sensors and other electronic devices, only costs about $100.

Darlox Electronic: The demand for FPC in the 5G era has greatly increased

Article is from: https://www.darlox.com/news/Darlox-Electronic-The-demand-for-FPC-in-the-5G-era.html

FPC is a kind of flexible circuit board made of polyester film or polyimide as the base material. It has the characteristics of lightness, thinness, high density, and foldability. For the current 5G smart phones, smart wearable devices and automotive electronics applications are very extensive, and this wave of technology will also bring a significant increase in demand for FPC.

1. FPC domestic substitution is imminent

From the perspective of global FPC output value, China is now a country with large FPC production capacity. According to statistics, China’s FPC output value accounted for more than 56% of global output value in 2018.  China is indeed a big FPC demand country, so now the domestic substitution of FPC is imminent, and the country is also vigorously supporting it, and there is huge room for it.

2. The wave of mobile phone replacement is accelerating, and FPC demand is increasing

On December 10, 2019, Xiaomi officially released its first 5G mobile phone at the press conference, which is also the first 5G mobile phone with a price of less than 2,000 yuan. This incident represents the democratization of 5G mobile phone prices, and the tide of 5G replacement will accelerate. It is expected that the shipment of 5G mobile phones will exceed 280 million units in 2020, and the substantial increase in mobile phone shipments will inevitably lead to a large increase in FPC demand and a surge in sales.

3. Stand-alone FPC usage has steadily increased, and is expected to continue to grow

From the previous functional mobile phones to the current smart phones, mobile phones are undergoing continuous update and iteration. With the continuous innovation of mobile phones, many intelligent application functions have been added at the same time, such as fingerprint recognition, multi-camera cameras, and virtual side buttons. And so on, and the arrival of these functions also makes the available space inside the phone continue to decline. At this time, ordinary PCBs will continue to decrease, replaced by foldable FPCs. In this way, the internal FPC usage of a single mobile phone will increase.

The future development direction of artificial intelligence

 The first trend is that all IT giants will deploy AI cloud services, AI-a-a-S, which means artificial intelligence as a service, which will become the future trend. AI is the future. It is a self-evident fact. New and old IT giants are not only actively using artificial intelligence in their own businesses, but also actively using cloud computing platforms to provide AI services to third parties.

From the supply side, IT giants are very clear that as long as third parties use their own platforms, they will leave data on the platform, and these data will be a big gold mine in the era of artificial intelligence. From the demand side, those application companies can use AI cloud services provided by large companies to enhance their competitiveness. Therefore, this is a win-win cooperation for both AI service providers and companies that use AI services.

The second trend is that new and old artificial intelligence companies will compete fiercely around smart entrances. In the Internet age, almost every entrance will cause competition, and the winner of every entrance competition will become the next giant. For example, in the Web2.0 era, the rise of interactive social networking has formed a social portal, creating Facebook and Tencent. The era of artificial intelligence is no exception. After the fierce competition, the next huge super enterprise will inevitably be born.

In the era of artificial intelligence, the main service portal is voice interaction in natural language. Natural language processing will be the main mode of human-computer interaction. Whoever can make the machine understand human language better will be able to win. Artificial intelligence will completely surround all aspects of our lives, which means that the competition for artificial intelligence portals will be more fierce, and the earlier you participate and the more users you get, the greater the chance of victory.

The third trend is that artificial intelligence will occupy the living room, and voice interaction will become the mainstream TV application. The concept of smart home has been shouting for many years. Bill Gates made a clear description in the 1995 Road to the Future, but such a description has not become a reality so far. The core reason lies in the lack of needs of users.

Nowadays, with the increase of TV screen size and the explosive growth of video content, traditional remote controls are becoming more and more difficult to meet the needs of people using TV. Voice-based smart search and smart interaction are rapidly emerging, and natural language interaction will become TV manipulation. The standard way of the machine. Traditional TV manufacturers such as Samsung, video content providers such as Netflix and Amazon, and IT manufacturers such as Microsoft and Google have all launched or will launch their own TV-centric voice interactive products, and smart homes are becoming a reality from the TV set.

The fourth trend is that smart toys will become one of the earliest successful application areas of AI. If AI is used to diagnose illnesses or make self-driving cars, people often cannot tolerate it making mistakes. But toys are different. People have a high tolerance for errors in toys. Therefore, today when artificial intelligence cannot surpass human intelligence, smart toys are precisely the entry point that allows artificial intelligence to gain initial market recognition.

In fact, there are already many successful cases. For example, at the end of 2016, the smart toy Cozmo, which can play games with people, was sold out until it was out of stock. A large number of smart toys will be launched in 2017. Although China's toy manufacturing industry is strong, there is no brand advantage. If Chinese toy companies cooperate with high-tech companies and use their strong manufacturing and marketing capabilities to launch their own brands, they will have huge business opportunities.

The development trend of wearable medical equipment

Industries related to medical and health care will all benefit from the further popularization or development of the new crown epidemic. Among them, the hardware that has greatly increased interest in the consumer market is wearable medical products. Including consumer-grade smart bracelets and smart watches that can provide real-time feedback on physical conditions and even detect infected persons. Professional-grade blood pressure monitors and blood glucose meters can be linked to the hospital system to assist doctors in remote consultations and so on. These dazzling arrays of hardware make the entire wearable medical device market present a certain prosperity, but so far no hardware product has become a "explosive".

Market conditions: 2023 is about to usher in an outbreak

There are currently two types of wearable medical products on the market. One is consumer-grade health hardware, such as mobile otoscopes, health bracelets, smart sleep systems, skin sensors, etc.; the other is professional-grade medical hardware, such as Talk about smart detectors, non-invasive blood glucose monitoring, blood pressure monitors, blood glucose meters, blood lipid detectors, etc.

According to third-party consulting data, the total sales of the global wearable medical device market in 2016 was 2 billion U.S. dollars, and it is expected to exceed 4.5 billion U.S. dollars in 2020. The compound annual growth rate (CAGR) between 2020 and 2027 is 25.78%. Industry development is full of vitality.

The upstream and downstream of its industrial chain will benefit from this dividend and have considerable market prospects. For example, the market size of sensors used in wearable medical devices will reach US$2.8 billion in 2024, with a CAGR of 21.6% from 2018 to 2024.

At the corporate level, wearable medical companies are mainly fighting for the competitiveness of the entire industry chain, so overseas manufacturers have relatively strong overall competitiveness. For example, overseas companies such as Fitbit, Jawbone, Apple, Samsung, etc., have established successful models in the wearable medical field by virtue of their huge sales network and technical support.

As for the Chinese market, the wearable medical industry emerged in the late 1990s, almost synchronized with international wearable medical equipment research. In May 2015, the State Council proposed "Made in China 2025", which listed the development of medical-grade wearable medical equipment as a strategic height, and required to improve its innovation capability and industrialization level.

According to third-party data, China's wearable medical equipment market has grown from 1.2 billion yuan in 2015 to 7.1 billion yuan in 2018. It is expected to exceed 12.2 billion yuan in 2020, and the value will exceed 20 billion yuan by 2023.

The development trend of wearable medical equipment

Trend 1. Under the epidemic situation, wearable medical devices enter more families

The epidemic will promote new uses of wearable medical devices, such as detecting infections in advance through effective algorithms that detect blood oxygen binding. According to IDC forecasts, by the end of 2021, approximately 70% of wristband wearable device companies will release products with algorithms and functions for early detection of signs of potential infectious diseases, including detection of COVID-19 and influenza.

At the same time, health care products and equipment are evolving into wearable medical devices. For example, companies such as Apple and Fitbit are seeking FDA approval to sell them as medical device wearable devices. According to the industry outlook, wearable medical equipment is like a "family doctor", and then binds back-end medical services to truly open up the medical channels for residents from the community to the specialist hospital.

Trend 2. Continuously evolving and perfect supervision

FDA is abbreviated from FoodandDrugAdministraTIon, the Food and Drug Administration. The FDA and CFDA continue to improve the wearable medical device regulations, which can set a benchmark for the wearable industry, and the development and production of products can be "aligned" with the standards, and standardize the industry to form a healthy development. At the same time, it can promote the realization of interconnection and help expand other business services.

According to the data, the wearable certification standards need to involve several major evaluation directions: chemical testing, battery life, battery and complete machine safety, applicability, software and information security evaluation, sensor accuracy evaluation, and wireless technology certification testing evaluation.

Trend 3. Combination of health big data and artificial intelligence

At present, more and more wearable manufacturers are integrating big data and artificial intelligence technology into medical applications, and they are cooperating with hospitals, healthcare organizations, research institutes and even traditional medical device companies to realize medical data data platforms. . For example, AppleWatchSeries6 can evaluate human health by monitoring blood oxygen level data. Another example is FitBit, an AI algorithm that detects in advance, which can detect nearly 50% of COVID-19 cases.

In this regard, IDC predicts that due to the threat of the new crown virus epidemic, life sciences and medical institutions will increase investment in artificial intelligence and advanced analytics by 30% by 2022 to avoid the danger of future supply chain disruption.

The new portable projector has a built-in large-capacity lithium battery with strong endurance, and it can continue to work for several hours even in a power outage.

Of course, a new USB-C interface is indispensable for a compact and portable projector. The USB-C interface, which integrates high-speed data transmission and up to 100W power transmission, has become the best choice for a new generation of portable projector power interface. Projection technology is currently mainly divided into two categories: DLP and LCoS. Among them, the core technology of DLP is in the hands of TI, and Texas Instruments (TI) can provide DigitMicromirrorDevice (DMD) chip products. The principle is mainly to switch the light through the control of the micro-mirror, so as to realize the precise control of the color scale and the gray scale. On the small DMD chip, there are nearly a million small mirrors that are smaller than a human hair. Compared with DLP technology, LCoS (LiquidCrystalon Silicon) chip technology, its main imaging principle is similar to liquid crystal LCD, but also through the micro-circuit control voltage to twist the liquid crystal, through the control of the polarized light of the liquid crystal, the light can be switched, thus Realize color scale and gray scale. Both technologies have their own advantages and disadvantages. In general, DLP technology currently occupies the mainstream position in the market. With technological innovation, DLP technology has more advantages in terms of image digital processing, seamless image delay, and long life.

The portable projector adopts the USB-C interface, and the data and power transmission can be realized at the same time through the USB-C interface. This interface can completely replace the traditional USB-A, Mirco-B, HDMI and DC interfaces, making the product more concise and beautiful. Huinengtai recently launched PDSINKHUSB238 with the smallest size and the most compact peripherals in the industry, which is very suitable for portable projector applications. The following is the typical application block diagram of Huinengtai USBPD power-receiving chip (USBPDSinkController, also called PD decoy chip) HUSB238 in DLPPico projector:

HUSB238 chip has passed the USB-IF certification, TID: 3666, integrated PD decoy function, load switch, over-voltage protection, over-temperature protection and other functions.

Automotive wiring harness production process

 With the continuous improvement of people's requirements for comfort, economy, and safety. The types of electronic products on automobiles are also increasing, and automobile wiring harnesses are becoming more and more complex. The failure rate of wiring harnesses has also increased correspondingly, which requires improving the reliability and reliability of wiring harnesses. Durability and other properties, many people are more interested in the process and production of automotive wiring harnesses. Here I will give a brief description of the knowledge of automotive wiring harness technology and production.

After the automotive wiring harness product drawings are released, the production process of the wiring harness must be combined. The wire opening is a station in the production of the wire harness. The accuracy of the wire opening process is directly related to the production schedule. Once an error occurs, especially the opening size is too short. , It will cause the rework of all stations to be time-consuming and laborious to affect production efficiency.

Therefore, in the preparation of the wire opening process, the opening size of the wire must be reasonably determined according to the requirements of the drawing, the stripping size standard operation guide, and clear and reasonable tolerances.

Make the operating instructions for opening the wire, cutting the wire, cutting the required length of the various wires required, and crimping the terminal to crimp the terminal to the wire. The terminal crimping is a very critical process, mainly to use standard terminal joints The jig is riveted. After the terminal and the wire are riveted, the tension, height, width, and riveting condition are all within the standard range. The riveting personnel in this process need to conduct self-inspection work, and a separately trained and qualified external inspector is required to conduct the terminal The full inspection work to ensure that the terminal riveting is 100% qualified. Then the plug is assembled, and the wiring position of the terminal should be paid attention to when assembling the terminal, and the terminal should be assembled in place to protect the contact terminal.

The final assembly will assemble various small strands on the tooling board and wrap it with tape, install various protective parts, and detect whether each break point of the fixture is unblocked, and the size, appearance, and performance are 100% tested.

The dimensions marked on the dimension inspection drawings should be measured one by one and controlled within the tolerance range.

The appearance inspection needs to be inspected according to the inspection standards, especially whether the contact part of the terminal is in place, whether the plastic case is damaged, etc.

Performance testing is the basic work of the product. It is necessary to ensure 100% of the tested products. During the testing process, attention should be paid to whether the test fixture is qualified, the number of times the test fixture is used, and whether the various parameter methods meet the standard requirements.

Due to the particularity and safety of its products, all work must be carried out preventive work to prevent errors. The stability and reliability of product quality mainly depends on detailed management. Only after every detail is in place In order to be able to make products that meet the requirements and satisfy customers.
