Code Reader
last update: June 1, 2015
You can apply up to three of the four unique filters developed by OMRON in the desired order to remove printing irregularities and noise, in order to achieve a stable reading.
Smooth
Smooths the image.
Erosion
For white codes, reduces the cell size.
Effective for reading separated dot codes.
Dilate
For white codes, increases the cell size.
Effective for reading codes with cell spreading.
Median
Removes noise.
Erosion and dilation can be combined to connect dots without changing the dot thickness.
Code Readers must be able to read codes even for poor printing conditions. You can automatically retry reading while changing the exposure time and other reading conditions, even for changing workpieces or environments, to enable a stable reading.
Reading is performed the specified number of times for the same scene.
Reading is performed until successful, as long as an external level trigger is input.
Reading is performed for the same scene while changing the exposure time in stages.
When reading DPM codes, inconsistencies in printing conditions can result in NGs if reading is performed with only one set of reading settings.
The FQ-CR allows you to register up to 32 sets of reading conditions as scenes and retry reading while changing the scenes in order.
The system automatically determines the scenes with the highest usage rates and changes the order to start with them to flexibly handle changes in reading conditions.
Of course you can specify a fixed order if required.
Red circles are displayed on cells for which the code was corrected on the display.
This clearly shows where the code quality was poor.
The wider the field of view, the more difficult it is to maintain consistent lighting within the field, causing errors in reading. The built-in LEDs of the FQ-CR Series use a unique OMRON DR optical system for effective light usage to maintain consistent lighting within the field of vision at a brightness that is four times that of previous models.
The HDR (high dynamic range) function minimizes the influence of changes in lighting conditions and light reflection. This enables stable inspections even for materials that are difficult to light evenly, such as metal parts or glossy films, or in locations subject to external light interference.
A polarizing filter is included to cut specular reflection from glossy surfaces. This enables stable code reading even for metallic or other glossy surfaces.
The compact body also provides an Ethernet connector so that you can transfer read data and images via Ethernet. Smoothly transfer data to PLCs, computers, or other host devices.
Setup is as easy as displaying codes on the monitor and registering settings with a simple procedure.
Then, the FQ-CR will automatically tune the settings to achieve the optimum conditions.
Use the convenient Touch Finder for on-site settings and control panel installations, or use a set-up tool on a computer.
TouchFinder for PC (Free)
After purchasing the Code Reader, you can download the TouchFinder for PC free from the member’s website.
The nine language support for menus means that you can easily introduce systems into factory sites in other countries.
In addition, you can easily change the language on a menu.
English
Japanese
Traditional Chinese
Simplified Chinese
Korean
German
French
Italian
Spanish
Navigation menus for operating procedures from image adjustment through to testing and starting operation are provided so that even beginners can operate the Code Reader.
The flexibly arrangeable platform can be used for simple configurations with one Code Reader for complex configurations with multiple Code Readers reading from different directions.
Up to eight Code Readers can be controlled from the Touch Finder set-up console.
The FQ-CR2 contains state-of-the-art algorithms that enable the reading of codes even with poor reading quality. However, even if the code quality continues to deteriorate for some reason, auto-correction and retrying are used to enable reading, making it impossible to tell where quality was lost simply from the OK/NG reading information.
Here, you can use the cell recognition rate information. The cell recognition rate changes with code printing quality, position inconsistency, installation conditions, and noise. You can log the cell recognition rate and image together to manage quality trends. The logging of recent results is useful for testing when commissioning a line. Run through some sample products and log the cell recognition rate. You can then display the results in a time-based graph to see how much leeway there is in reading performance.
* For the FQ-CR1, the number of detected characters is logged instead of the cell recognition rate.
If you leave the Touch Finder installed on-site, the recent NG sensor display is very useful. Even if you are monitoring more than one Code Reader with the Touch Finder, the display automatically changes to the Code Reader where an NG occurred so that you can quickly confirm conditions.
