With the transformation of industry 4.0 and manufacturing industry and the continuous promotion of digital construction projects, the overall scale of the manufacturing industry continues to expand and the level of intelligence continues to improve. The demand and awareness of downstream industries for machine vision are also gradually improving, which has driven the steady growth of China\'s machine vision Market.
The application of machine vision inspection system technology has run through the whole automobile body manufacturing process, including the development from the initial quality inspection of raw materials to the 100% on-line measurement of auto parts, controlling the welding, gluing, punching and other technological processes in the manufacturing process, and finally checking the quality of the body assembly and the finished vehicle.
In the automobile manufacturing industry, machine vision involves almost all the manufacturing processes of systems and components, such as body assembly inspection, panel printing and quality inspection, precision measurement of part size, surface defect detection of industrial parts, etc.
机器视觉应用于高精度制造和质量检测，包括圆晶切割、3C表面检测、触摸屏制造、AOI 光学检测、PCB 印刷电路、电子封装等。
Machine vision is used in high precision manufacturing and quality inspection, including wafer cutting, 3C surface inspection, touch screen manufacturing, AOI optical inspection, PCB printed circuit, electronic packaging, etc.
With the introduction of non-contact measurement technology, machine vision has gradually developed into online measurement systems such as fixed on-line measurement station and robot flexible online measurement station, which can strictly monitor the body size fluctuation and provide data support.
Visual guidance technology has gradually penetrated into the whole process of automobile manufacturing, such as guiding the robot to carry out the best matching installation, accurate drilling, welding seam guidance and tracking, spraying guidance, windshield loading guidance and so on.
Machine vision inspection system can carry out manufacturing process inspection, automatic tracking, traceability and control of products, including obtaining body part code through optical character recognition (OCR) technology to ensure the traceability of parts in the whole manufacturing process, ensuring the integrity of component assembly by identifying the existence or absence of parts, and identifying the surface defects of products by visual technology Whether there are defects in the tools to ensure the production quality.
With the continuous deepening of automation and intelligence in various industries, the machine vision equipment market will still show a stable growth demand after a short \"cold winter\". China\'s machine vision industry market is mainly composed of electronic manufacturing industry, automobile, pharmaceutical industry, food and packaging machinery and printing machinery.
