Semiconductor and electronic equipment manufacturing industry is still the most important application field of machine vision, and also the most important driving force for the development of global machine vision market. From the perspective of international machine vision applications, 46.57% are concentrated in the semiconductor and electronic industries; according to the 2017 annual report of global machine vision leader Cognex, consumer electronics is also the most important source of revenue, accounting for 40%. Its sales revenue in Asia increased by 63%, while that in Europe increased by 40%, mainly due to the contribution of consumer electronics.
Applications of machine vision
Although machine vision has been widely applied in semiconductor and electronic industry, which consists half of the entire machine vision market. We believe that the semiconductor and electronic industry will still lead the development of machine vision industry for a long time in the future, based on the manufacturing needs of semiconductor and electronic industry.
From the perspective of manufacturing technology, semiconductor and electronic equipment manufacturing has a rigid demand for machine vision. Machine vision is naturally suitable for high-performance, precision professional equipment manufacturing, which is why the relevant industries can drive the rise of the entire machine vision. In the field of semiconductor manufacturing, the precision positioning and visual measurement of machine vision are required in the front and middle stages of semiconductor manufacturing. In the later stage of wafer manufacturing, a large number of machine vision technologies are needed in the electrical inspection, cutting, AOI packaging, inspection and other processes. Machine vision has obvious advantages in speed and accuracy in the semiconductor manufacturing process. In the field of 3C manufacturing, the manufacturing of components and main body also needs the assistance of machine vision, almost 70% of the machine vision units are applied in these areas. In addition, machine vision is also needed for connector detection, PCB negative film inspection, hard disk detection, robot vision guided positioning, online component classification and screening, and barcode reading. Due to the high requirements of manufacturing technology, semiconductor and electronic equipment manufacturing has a rigid demand for machine vision.
The automation level of China's electronic equipment manufacturing industry is still relatively low compared with developed countries. According to the employment figures released in March 2018, the number of employees in China's 3C equipment manufacturing industry has reached 8.32 million, far higher than other downstream application fields, but the degree of automation is relatively low. China has concentrated 70% of the world's 3C production capacity, but in 2015, the density of industrial robots was less than 20 sets / 10000 workers, while Japan and South Korea had reached 1180 and 1100 units / 10000 workers respectively. Compared with the automobile industry, the density of industrial robots is close to half of that of developed countries. China's 3C industry automation upgrade space is larger, and machine vision will also get sustainable development.
Visual inspection system is the "eye" of industrial automation production. It plays a key role in consumer electronics, semiconductor, automobile, intelligent security, health care and other industries. The annual growth rate of market scale is about 20%. In 2019, the scale of machine vision market in China and the world is more than 12 billion yuan and 10 billion US dollars respectively, which is basically monopolized by the two giants: Cognex of US and Keyence of Japan. On the one hand, machine vision is the basic core technology of intelligent manufacturing. On the other hand, the demand for visual inspection is changing rapidly from two-dimensional to three-dimensional, especially due to the iterative upgrading of products in consumer electronics, semiconductor and other fields, the three-dimensional defect detection of glass and transparent flexible film, micro precision electronic and metal parts is more demanding. The traditional two-dimensional and three-dimensional visual inspection technology are facing great difficulties, and the market are calling for new technologies, new solutions to meet the new challenges. It is the vision and mission of VOMMA technology to create an independent and controllable intelligent manufacturing eye and fill the blank of "transparent, thin and micro" three-dimensional detection technology.
VOMMA technology has become the one of the very few light field 3D imaging technology company in the world and the only one in China that has fully mastered all the core technologies of optical design, manufacturing, 3D light field rendering and 3D defects detection.
