The 3C electronics industry has become the largest application field of machine vision.

Machine vision is widely used in various industries. 3C electronics is one of the largest application markets. Machine vision plays an important role in positioning assembly, parts inspection, or whole machine product inspection.

With the development of 3C electronic manufacturing in China, China has established the most advanced electronic manufacturing factory in the world, and machine vision technology will also play a greater role.

01, 3C Electronics becomes the largest Application Market

In recent years, with the rapid development of AI artificial intelligence and algorithms, machine vision is more and more widely used in the downstream market, and has penetrated into battery, printing and packaging, food processing, beverage, tobacco, glass, medicine and other industries.

At present, 3C electronics is the largest downstream application industry of machine vision. according to public data, the 3C electronics industry accounts for 52.9% of the downstream applications of machine vision, making it the largest market downstream.

China is a large manufacturing country. With the continuous development of technology and the continuous expansion of market demand, with the rapid development of 3C electronics industry, China has become one of the important pillar industries in China. At present, China has become the world's largest 3C industrial R & D and manufacturing base, with an overall market size of more than 6 trillion yuan.

The huge market scale provides superior development conditions for the application of machine vision in 3C fields. in terms of 3C electronic manufacturing industry, including components, parts and finished products, quality inspection and measurement can be carried out through machine vision technology.

With the continuous upgrading of consumption, the domestic intelligent electronic market is expanding, especially the increasing demand for high-end smart phones and smart notebooks, which also provides favorable conditions for expanding the application of machine vision, and with the gradual intensification of market competition, major manufacturers are making great efforts to improve processing efficiency and product accuracy, and the penetration of machine vision technology will be further improved.

02. The product has fast iteration and high precision, which becomes the driving factor.

3C electronics has become the most important application field of machine vision, which has its inevitable reasons. First of all, the 3C electronics industry has rapid technological innovation, faster product iteration and shorter life cycle. "if you buy a smartphone today, it may be out of date next month." this has become a common phenomenon. this leads to the increasing frequency of consumer demand for 3C electronics and the gradual expansion of the 3C electronics market. Where there is demand, there will be supply, and the expansion of demand in the downstream market will continue to stimulate the continuous upgrading of testing business.

However, it is worth noting that under the increasing market demand, if only through manual detection, it is very easy to cause damage to human eyes under long-term naked eye recognition, and this kind of damage is irreparable. In this case, machine vision can effectively meet the huge market demand for detection and identification because of its strong anti-interference, high precision, safety and high efficiency.

Secondly, taking the mobile phone as an example, the chip packaging pins in the upstream industry of the mobile phone are getting denser and denser, the number of solder joints on the internal circuit board is huge, and the design compactness and structural dimension accuracy of the mobile phone are gradually improving. consumers' requirements for the appearance of high-end mobile phones are also increasing, so all links need to be detected and identified through machine vision technology.

Specifically, the application of machine vision in 3C electronics industry mainly includes in-process inspection, key size measurement and full size inspection. In the inspection link of the manufacturing process, the multi-size measurement can be completed accurately, and combined with big data, the source can be located quickly; in the key dimension measurement, such as screw hole size measurement, key profile measurement, and signal and welding related dimension measurement, the product inspection can be completed quickly. Full size inspection is the measurement of all assembly positions, including the measurement of aperture length of electronic products, the leakage of uncertain feature structure matching measurement, and so on.

In the long run, the application scale of machine vision in 3C electronics industry will continue to expand. As mentioned earlier, the life cycle of 3C products is short, the repurchase rate of consumers is high, the major manufacturers need to produce electronic products frequently, and the application demand of machine vision is increasing.

And with the electronic products becoming more and more intelligent, the product structure is becoming more and more complex, the requirements of production lines for production efficiency and processing accuracy are greatly improved, and the permeability of machine vision in the industrial chain will continue to improve.

03, machine testing, help mobile phone "intelligence" in the 3C electronics industry, Apple is an insurmountable brand. Apple's management of the supply chain has a profound impact on global manufacturing. In the quality control of Apple supply chain, most of the links are based on machine inspection, and the passing rate of machine vision inspection has become the key to quality control in the supply chain.

This puts forward the requirements for the upstream and downstream enterprises of the 3C electronics industry, and the detection and identification through machine vision technology has become a rigid requirement in the whole manufacturing process.

From the perspective of specific application scenarios, take smart phone products as an example, for example, in the identification link, through machine vision technology, the use of color measurement tools, the cable color can be analyzed and judged to ensure the accurate location of cable insertion. In the positioning link, the headphone hole can be located, and it also plays an important role in the MIC fitting positioning of the mobile phone screen.

Of course, the most application scene is the detection business. in the detection link, we can use the "machine eye" to detect the phone key character position and edge outline, and detect the problems such as missing welding, less welding, connecting tin and so on. For the mobile phone chip, we can detect the defects such as dirt and scratches on the chip surface. For the appearance of the mobile phone battery, we can use a variety of combined light sources and image algorithms to detect the battery surface defects. Such as battery scratches, bumps and bumps, dirty stains and so on.

In addition, the size of mobile phone screen and mobile phone shell can be detected by machine vision, which greatly improves the production efficiency and detection accuracy of the production line.

At present, the global 3C electronics industry has transferred to developing countries, and China has gradually become the largest manufacturing base of electronic information products in the world. With the continuous increase of application scenarios, the penetration of machine vision in 3C electronics industry is expected to continue to improve.
