Application of machine vision technology in various industries in 2017

  The machine vision system uses machine vision products (i.e., image capture devices, divided into CMOS and CCD) to convert the captured target into an image signal, and transmits it to a dedicated image processing system to obtain the morphological information of the captured target. According to the pixel distribution and Information such as brightness and color is converted into digital signals; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the on-site equipment actions based on the discrimination results.
Machine vision systems are used in production equipment in various industries to help upgrade industry equipment, improve production line technology, and improve product quality and yield. It is one of the core technologies of modern industry. Machine vision technology has been widely used in touch screens, FPD, laser processing, solar energy, semiconductors, PCB, SMT, robots and factory automation, food and beverage, pharmaceuticals, consumer electronics processing, automobile manufacturing and other industries, greatly improving product quality, Reduce production costs and improve human material and spiritual satisfaction with industrial products.
Touch screen
With the development of technology, people have higher and higher requirements for the interactive experience of electronic products. As a new generation of electronic product input device, touch screen is gradually becoming the new favorite of tablets, mobile phones, e-books, GPS, game consoles and other devices. The touch screen production process is complex, from the upstream ITO glass coating, photolithography, and IC component processing, to the midstream touch screen module lamination, screen printing, and cutting, to the downstream touch screen module lamination and cover glass inspection. Higher requirements are put forward for the process, making machine vision technology a necessary technology for production and quality inspection in related links.
FPD
The FPD industry includes LCD, LED, OLED and other display devices. Various technical processes are very complex, among which LCD is the current main display technology. The FPD industry has extremely high requirements for production efficiency and product quality. Machine vision technology has become an indispensable technical means for non-contact, high-precision, high-speed production and inspection capabilities. From the front-line ITO glass inspection and backlight module inspection , to Cell lamination, LCD module COG equipment, alignment lamination, cutting machines, flying probe detection equipment, etc. The application of machine vision technology has improved the core competitiveness of equipment manufacturers.
Laser processing
Laser processing is a widely used industrial processing technology that uses the motion control of lasers to achieve high-precision marking, cutting, engraving, welding and other functions. With the upgrade of laser processing technology, traditional technology can no longer meet the high-precision and high-speed requirements of industrial processing. This has led to the integration of machine vision technology and laser processing technology. High-precision processing can be achieved through visual positioning and guidance, reducing the need for high-precision processing. The demand for cost-precision fixtures improves equipment accuracy and reduces processing costs.
As one of the valuable future green energies, solar
energy is a key industry field for national development. The short-term relative overcapacity has put forward higher requirements for solar cell production equipment, from the purity of silicon ingots and silicon wafers to the quality of the processing and coating process. Control will affect the photoelectric conversion efficiency of the final solar cell. High-quality production lines can reduce the scrap rate, thereby reducing the production energy consumption and solar cell output ratio, making solar energy a truly clean energy. In the solar cell production process Among them, through the use of machine vision positioning, measurement, detection and other technologies, the yield rate can be greatly improved and the production cost can be reduced.
Semiconductor
Semiconductor technology is the foundation of the modern information industry and the earliest birthplace of machine vision technology. In the 1990s, European and American semiconductor companies applied image technology in the semiconductor industry, which later gradually developed into today's machine vision technology and became an indispensable key technology for semiconductor processes. At the same time, the scale of the semiconductor industry is huge, and the industry Moore effect continues to pose challenges to industry processes, and the requirements for machine vision technology in its production equipment continue to increase.
PCB
PCB board is the main product carrier of electronic information products. Today, when the PCB industry is relatively mature, competition in the industry is fierce, and the requirements for comprehensive manufacturing capabilities of high-performance equipment are getting higher and higher. With the development of multi-layer board manufacturing technology, higher requirements have been put forward for PCB production technology. Machine vision technology has been widely used in the PCB board manufacturing process. In film AOI, PCBAOI, PCBAVI, inner layer board AXI, PCB screen In printing, automatic exposure machines, SPI, punching machines and other equipment, visual technologies such as machine vision positioning and detection can achieve fast and accurate quality inspection and process control, improve product quality and production efficiency, and are a reliable guarantee for improving equipment performance.
SMT
The SMT industry is another key electronic information industry after PCB. It is also the birthplace of Chinese machine vision equipment manufacturers. The miniaturization of electronic components, high-density device mounting, and the complexity and diversification of device pin arrays have all given rise to modern SMT. Equipment puts forward higher requirements. Through the use of machine vision positioning, measurement, and detection technologies, we can improve the production efficiency of SMT equipment, improve placement accuracy, improve continuous work stability, and help equipment upgrades in the SMT industry.
Robots and Factory Automation
Industrial robots are multi-joint manipulators or multi-degree-of-freedom robots oriented to the industrial field. They replace manual labor in performing monotonous, frequent, long-term operations, or operations in dangerous and harsh environments, such as stamping, Processes such as pressure casting, heat treatment, welding, painting, plastic product forming, mechanical processing and simple assembly are important indicators of the automation level of modern factories. The combination of robots and machine vision technology can complete more precise assembly, welding, processing, transportation and other tasks.
The production and processing of pharmaceutical
drugs is a very strict management process, and any small error may cause serious consequences. Through machine vision, we can achieve quality control and management control of the drug production process, improve drug quality and packaging quality, and ensure the safety of patients.
Logistics
Modern industrial production logistics management is the embodiment of modern production efficiency and advancement. Through the identification and tracking of bar codes and character codes, a one-to-one correspondence between raw materials, finished products, and packaging boxes can be formed, making modern production manageable. , traceability. For the production process management and device traceability of industrial products, for the prevention and safety traceability of food and beverages, parts traceability in the automotive industry has very important application significance.
