Due to product micro and trend to high speed production, next-generation optical detection demands high-speed image transmission, and high parsing degrees and the color image retrieves function, AdLINK technology volume measuring and automation products Department senior associate Yi Huang home recently in seminar in the said, high parsing degrees and high-speed image transmission for detection automation field of important trend, which, plane display (FPD) and phone industry will is with potential of application market.
In order to save manpower costs and reducing manual testing failures, in Taiwan, machine vision has been widely used in the semiconductor, Panel and energy efficiency, including flat panel displays (FPD), printed circuit board (PCB), light emitting diode (LED) and solar (Solar cell) of production and testing equipment.In addition, tooling, screws, Diamond Head artifact detection equipment using machine vision technology for detection, including artifacts have no judgments, bar code identification, location, dimensions, measurements, colour detection and flaw detection testing, printing and so on; in terms of screw testing can detect cracks and other defects of the screw head and pitch dimensions such as length, RADIUS, measured.
YiJia Huang said: "the current main customers for PCB machine vision equipment factory, will continue to grow in the future and the phone itself is a high growth industry, so that the hand is also an important target customers of AdLINK;Passive electronic components including capacitors, resistors, and steady development trend and FPD, automated optical inspection (AOI) technology, at wire image capture (line scan) is recognized as the most productive way; machine vision equipment can be used in FPD broken edge detection, check the edges for damage, nicks and scratches, and other defects. 」Panel size increases, as well as improved resolution and high-pixel camera can help reduce acquisition times and the complicated nature of the movement.Japan Toshiba Teli machine vision and medical imaging business unit Vice President and technology on the river and pointed out: "Visual inspection cameras currently on the market are mostly dominated by 6fps and 8fps, Teli provides high-quality industrial cameras can provide 12 million pixel high 25fps high speed image processing with a resolution of up to 4096x3072.He stressed that in terms of efficiency, setting up a 12 million pixel camera equivalent of erecting 49 VGA cam work.
Digitizing is also an important trend of industrial cameras. On the river and pointed out that Thai forces on share sales, analog camcorder is still the norm last year, accounting for about 60% of the revenue, But have a tendency to gradually was replaced by digital cameras.Transmission in digital camera interface, Firewire, its remarkable growth over the past four years, especially the FireWire 800 (IEEE 1394b).In terms of resolution, VGA is mainstream, but the proportion of market share decline last year only accounted for 60% sales and solution definition of over 4 million cameras, and its annual increase in revenues during the past four years.
In terms of vision inspection market, currently at 80%, still using black and white photography.European Euresys company Senior Vice President Marc Damhaut said: "Euresys color image capture technology, and possess the ability to synchronize retrieves RGB color, and the ability to handle a large number of images, has been used in Korea and Taiwan on the next-generation flat-panel display industry and PCB applications. Euresys video card image pretreatment technologies accessible white balance and color conversion and color corrected images, without taking up CPU resources.
AdLINK technology think of high-speed, high-resolution, color machine vision needed to rely on faster trigger speed (Trigger), high resolution and high speed cameras, with a high bandwidth bus (BUS), and PCI-Express will be the main image capture card interface.PCI-Express for mainstream bus standard, Yi Huang Jia pointed out that niche applications of machine vision is PCI-Express one of the PCI-Express have a higher bandwidth than PCI and support point-to-point high-speed serial information transmission, transmission speed, memory space, guaranteed bandwidth on the speed and resolution of system stability and production is better than PCI interfaces have the advantage.
Machine vision is also widely used in the energy industry, including AOI inspection of LED and solar energy, in addition to depending on the solar panel testing requirement, LED by Wafter/Chip point in measuring and sorting, could also be used for machine vision to precision positioning, and check the solder pads, light and cutting appearance.
