When the most popular machine vision is in progres

  • Detail

The survey of machine vision shows that the simplicity of operation provides a good experience for users. Don't hesitate, users think it's time to use machine vision

look forward to such a scenario: the hardware and software that eliminate all obstacles to high-speed operation drive the robot, and read the characters on parts and labels with zero error rate. A recent survey by control engineering and reed research group shows that many subscribers of machine vision devices are for such or other purposes - many of them have achieved success, while others are facing installation problems. A total of 94% of bookers expect to invest funds with the same or more operating knowledge of oil delivery and return of hydraulic universal testing machine in the next 12 months for machine vision equipment, and 52% said they expect to invest more. One respondent said, "the use of vision system can eliminate the high cost of causing customer dissatisfaction. Now it seems that this should be a tool that should have been used several years ago." (two patented products and the latest products of several major manufacturers will be introduced below.)

machine vision is used far beyond quality control. As shown in the histogram below, among the investigated objects, barcode reading, product inspection, assembly drive and machine operation control are the most important applications. The survey in 2007 shows that the utilization rate of machine vision is gradually increasing, and the main problem is installation. Not surprisingly, 30% of the respondents used integrated machine vision providers to help install, while 15% of buyers who did not use integrators said they planned to use integrators next year. We also found that the latest machine vision products from major manufacturers (see below) focus on ease of use

performance, support

the respondents believed that the characteristics of machine vision should be listed in order of importance: performance, ease of use, technical support, easy installation, having a complete solution (including software), ruggedness, price, customization ability, speed, complete tool set and expert integration

the results of the survey show that among the main networks currently used in machine vision, 81% are Ethernet tcp/ip, 74% are RS-232, 58% are private networks, 57% are ma, 53% are Gigabit Ethernet, 50% are V, 49% are USB, 49% are DeviceNet, 42% are connected through photography, and 41% are connected through other protocols of Ethernet

the restrictions encountered in the use of machine vision are listed in order of importance: capital budget, connection priority with other automation projects, engineering resources, acceptance of factory employees, understanding of visual technology and difficulty in use

among those who bought machine vision last year, 20% bought 1 to 2 sets, 38% bought 3 to 6 sets, 22% bought 7 to 15 sets, and 19% bought more than 16 sets. Among them, 44% use the so-called "agile vision sensor", while 82% think this sensor meets their requirements. Less than half (42%) thought the use of machine vision was too complex or expensive

users like easy installation

interviewees were asked why machine vision meets their needs. In their evaluation, 14 items are related to use, of which 4 points out that mechanical display devices are superior to other sensors in use. Eight items are related to configuration or accuracy, and the other eight items are related to ease of use

the evaluation on configuration includes: being able to integrate the whole system into one camera. Eliminates positive errors caused by light and color. The measurement is fast, repeatable, accurate and has a wide detection range. Agile sensor elements have quality assurance in color inspection. Although the installation requirements are high, it is trustworthy. Such a system can liberate the computer from anti mosaic, color correction and other cumbersome operations

users reported that machine vision is easy to use and convert, meets or even exceeds their expectations, provides convenience for maintenance personnel, and shows a good return on investment (ROI)

special applications of machine vision include filling and packaging systems, timed delivery systems, and process control. Other feedback suggestions are: we are aware of the display limitations of this sensor; They perform well in the recommended areas. We need a really good camera. It is found that such agile sensors are trustworthy. For complex sensing requirements, visual sensors are reliable

avoid mistakes

for the purpose of helping others, the respondents shared the reasons why the visual system could not meet their needs: 3D monitoring was unsuccessful; The sample identification in the production process is not satisfactory; The option of multi-step operation cannot be selected on the same mechanical equipment; Insufficient tools; Need a high-end system; Operation needs real-time monitoring; Operators need too much training to integrate new products; The sensor cannot achieve a high level of repetition; During the inspection, the visual sensor cannot provide the function of interruption or cancellation

however, positive evaluation is always more than negative evaluation. One respondent was surprised why machine vision was not used more frequently. He compared the use of machine vision to "the simplest and most reliable way to solve problems with the best fault tolerance". The electronic control experimental machine controlled by microcomputer uses an electronic extensometer to detect the deformation rate and collect the list of major machine vision manufacturers that the respondents have purchased in the past 12 months is listed below. In descending order, they are: Cognex (DVT), banner engineering; Keyence; National Instruments; Omron Electronics; Matrox Imaging; IPD (a group of DALSA digital imaging); PPT Vision; Siemens(RVSI Acuity CiMatrix); Systech International; Jai pulnix and Toshiba. Another 19% of the respondents chose products from other companies

the smallest high-performance ID recognizer

the high-performance fixed ID recognizer DataMan 100 of Cognex company can recognize a wide range, from printed bar codes to the most difficult 2D direct marked codes (direct marked C, which is a policy to protect the fundamental interests of the country and the people). This recognizer is said to be smaller than a flip, but it provides unparalleled coding read-write performance and simplicity. It uses idquick software, a new tool of Cognex for ultra-high speed encoding and decoding. A model installed with the widely acclaimed idmax software can also read the most difficult DPM code. All DataMan 100 recognizers are integrated with lighting, buzzer, adjustable optical components, built-in sight and a key, so it is easy to install. This recognizer is suitable for identifying one-dimensional or two-dimensional codes on automobiles, packaging, electronic products, medical equipment and pharmaceutical products

monolithic or split color visual sensor

barner Enginnering recently launched two visual sensors for color monitoring: a monolithic presenceplus P4 color Omni and another presenceplus Pro color sensor with a compact camera and an independent control device installed on the DIN rail. They all use color matching tools to detect specific colors, and can detect any color changes. Their characteristic is that the color resolution reaches 752 × 480, which adopts CMOS photosensitive elements and includes all presenceplus visual tools: positioning, pattern recognition and counting, pattern recognition and counting, and edge, object, delay, average gray scale measurement. This kind of sensor can be applied in occasions where color is the main feature, such as automotive fuse verification, tablet color matching, led position correction and color consistency monitoring

more flexible and simpler visual software

national instruments released the third edition of Ni vision builder for automated inspection. The latest version upgrades the interactive software for configuration and benchmark verification, as well as the write free program for the full deployment of machine vision. This version introduces a new state machine process model, which is said to provide engineers with the most flexible environment for configuring electronic eyes. Engineers can customize the operation process of inspection and calmly face the challenges of component arrangement, partial inspection and verification. With the help of state machine, vision builder AI combines the flexibility of programming language with the ease of environment configuration

patented simple color display

omron's new generation FZ color display sensor adopts true color technology and intelligent camera, which can reliably and automatically detect objects with low color contrast at high speed. Omron's advanced true color sensing engine (arcs) captures and processes 16.77 million colors, which is close to the color perception ability of the naked eye. This engine is externally represented as a system using monochrome or wrong color contrast conversion and analysis methods. The company said that this is the only system in the industry equipped with four camera traps and real color switches. Its controller can be installed in a traditional box unit, or it can be installed inside an LCD touch screen in consideration of reducing space. Images and tool settings can be displayed on the screen, just a simple drag and drop installation. The function allows changes to be made in case of connection. Activation software is also embedded in this system

patented improved vision device

the va3x display device introduced by DALSA IPD can be installed in a compact DIN portable device. It provides users with fast installation, has good factory wiring, and can support one or two cameras by selecting different sensor resolutions. Its performance is more than twice that of traditional va2x products, both of which have the same pins and software. Va3x has been upgraded in terms of processor and system resources to support devices that need stronger processing power and higher image resolution. Va30 includes easy-to-use and plug and play inspec software, while va31 includes Sherlock, a machine vision software that is said to be the top in the industry. The user interface and flexibility can meet the needs of different users and integrated machine vision
