ZFX Machine Vision Sensor

ZFX-CD Series Code Reader can read major bar code and 2D code, including GS1 Databar.

Step 1: Choose Best Lighting

By just selecting the best one from the candidate images (automatically captured by changing the lighting pattern with auto-lighting), anyone can easily find the optimal lighting. User can now easily determine settings for shiny work with high degrees of reflection and black monochrome work with low degrees of reflection, something very tricky before.

Step 2: Choose Measurement Icon

The measurement method can be specified by just choosing the icon from out of a total of 9 measurement items for different types of inspection.

Step 3: Draw Region, Press and Go

Just specify the region of interest and press Auto key and the system will determine the most suitable parameters for the target image.

Customized setting is also possible by fine tuning the parameters automatically set up. The time required to set up parameters can be significantly reduced.

Visualized Setting and Monitoring

Despite its small form factor, the enlarged screen significantly improves the visibility and the ease of operation. The method of operation can be selected from 3 ways - the touch pen, keypad or console.

Rich Interface Support

ZFX automatically detects the connected camera and displays the appropriate menu. With rich selection of interface including parallel RS-232C/RS-422, USB 2.0, the extensibility is superior.

Built-in Lighting Camera (Triple-speed camera (IP65))

Line up of 6 types of built-in lighting cameras that do not need lighting selection or setup. The color camera can respond to a wide range of work with a 5-150mm field of view. Through image compression and partial capturing, it can support a high-speed line.

C-mount Camera Unit (Triple-speed Camera)

This product line of ZFX Machine Vision Sensor includes C-mount camera that can select the lens to match the field. It can be used in combination with optional lighting such as transmitted lighting, low angle lighting and bar lighting, etc. to support different inspection types.

Automatic Color Filter

Even for images clearly distinguishable in color, when converted to monochrome the contrast tends to become low. Color filter analyzer automatically selects the optimal color filter (auto color filter) based on the image analysis result to adjust the contrast, to allow for stable image measurement. Any intermediate color can be arranged for the color filter using custom settings.

Image Storing and Re-measurement

ZFX Machine Vision Sensor stores up to 100 files of image data in the main memory without slowing measurement speed. Images data can be re-measured so even with a high-speed line, for example, the results of the measurements can be checked at leisure afterwards.

On-site Fine Adjustment

On site variety adjustment of work is essential. Without returning to the menu mode, the measurement region, color contrast setup and so on can be tuned in adjust mode, using double screen to compare with the original image. The measurement results of the stored images can also be displayed so the unnecessary rejects can be efficiently reduced.

Pattern Search

The shape measurement is a fundamental algorithm for image processing. By adopting a new image processor, the pattern search achieves a balance in the three factors of speed, precision and stabilization, something that was an arduous task until now. It now supports a 360-degree revolving search and a sub-pixel processing of 1000 to 1 pixel units as well as a multi area searcher. The robust pattern search can respond to the multitude of inspects and measurements of any application.

Sensitive Search

When it comes to the difficult processing of detecting small differences, the Omron's
unique sensitive search matches work at a smallest detail and in doing so makes such detection all the more possible. It resists variations in position and density to capture even the smallest detail in the complex patterns.

Defect

It is used to detect smears, scratches, chipping and burrs on the work. Defects are displayed on the screen, which makes it ideal tool for visual inspection.

Region

Detects the existence of work within a region and measures its size based on the area to perform various classification.

Hue

The three factors in color, i.e. hue, saturation and brightness value, are measured and digitalized. And whilst an accurate differentiation of the color is performed, it is also possible to measure the color variety with the deviation measurement function (with color camera connected).

Bright

Measures the brightness within a region. It can be used for checking the presence of a component, etc., by generating average density and density deviation values.

Position

The existence or not and the position of the edge is measured. Oblique edges can now be measured even in complex conditions and even more accurate position measurements can be taken. The peak bottom measurement function that can accurately capture the edges is now supported.

Width

The width of the edge is measured. By using the edge partitioning method, it is possible to measure the maximum and minimum width.

Count

The number of edges inside the area is counted. Based on the number of edges on the pre-registered good model, it counts the edges in the area and determines the correctness.
