Since the beginning of the use of circuit board terminals in China, the sales volume has increased all the way, once surpassing the rail-type terminal blocks, becoming the main force of the connector. In recent years, with the development of intelligent manufacturing, circuit board terminals continue to exert their strength with the advantage of small and precise. Machine vision is one of its applications.
Machine vision was proposed in the 1960s, until the 1980s and 1990s, machine vision ushered in a boom, and after the 21st century, machine vision technology entered a mature period.
Machine vision can be called the "window of the soul" of industrial automation, whether it is object or bar code identification, product inspection, appearance size measurement, mechanical arm or transmission equipment positioning, etc. are inseparable from machine vision technology, therefore, with intelligent manufacturing The development of robot vision has also ushered in new application requirements.
With the market's favorable conditions and the maturity of various high-tech, various robot industry policies, such as Germany's "Industry 4.0", Japan's new robot strategy, the US Advanced Manufacturing Partnership Program, China's "13th Five-Year Plan", "Made in China 2025" have been introduced. Promote the continuous growth of the industrial robot market and greatly promote the development of the machine vision industry.
Compared with the strategic deployment of artificial intelligence (including machine vision) in countries around the world, the United States, Japan, and Europe have been implementing the rush strategy. The artificial intelligence plan proposed by the United States in the White House; Japan's Toyota acquisition of Boston Dynamics; the EU's "human brain plan" and "graphene" are their strategic trends in artificial intelligence.
According to public data, in 2018, the global market for machine vision technology for industrial automation reached US$4.44 billion, and it is expected to reach US$12.29 billion in 2023, with a compound annual growth rate of 21%.
China's machine vision technology started late, and China's machine vision technology application stayed in the field of semiconductor electronics earlier. Although China's machine vision market started late, China's downstream industry has become more widely used and developed rapidly. Therefore, China has become the third largest application market after the United States and Japan.
In recent years, China has made great breakthroughs in the development of the machine vision industry. From 2011 to 2017, China's machine vision market jumped from 1 billion yuan to 7 billion yuan, maintaining a double-digit growth rate every year. China has vigorously developed semiconductor electronic equipment. With the global semiconductor market surpassing the $400 billion mark, the robot industry has also advanced by leaps and bounds. The machine vision market, which is the robot "eye", has also risen. The development trend of automation and intelligence in various industries is expected to exceed 20 billion in the machine vision market in the next five years.
The most widely used connectors in machine vision are plug-in terminals, where spring insertion is most convenient. On the one hand, the spring plugging and unplugging adopts the plug-and-pull structure of the plug-in terminal, and on the other hand, the spring-type terminal is used to fix the elastic piece, which is a terminal with convenient installation and convenient wiring, and is also the main product of Lianjie Electric.
