FH / FZ5 Series Vision System/Features

By OMRON Electronics

Easier to Embed in Machine, Shorter Machine Cycle Times

 

Increase Machine Speed

Process Higher-resolution Images without Increasing the Machine Cycle Time [FH]

High-speed Image Input (Fastest: 3.3 ms)

Camera resolution, driven by higher expectations for quality, continues to increase. OMRON has greatly reduced the input time and image transfer time to provide high-speed processing to match the speed of Machine applications for high-resolution images. Even with more Cameras and higher resolution, high-speed image input will contribute to increasing throughput.

 

Ultra-high-speed Searching (Shape Search Ⅲ)

 

New technology makes search algorithms nine times faster than before. 
Even for unstable image conditions, including light interference, overlapping shapes, gloss, and incomplete images, stable searching is possible without reducing speed, resulting in a increased stability.


High-resolution Cameras capture large amounts of data, which can make a bottleneck out of the transfer speed time in addition to the image input time bottleneck. An FH-series Controller provides a faster, multi-line image bus to enable realtime transfer of large amounts of image data for high-resolution Cameras or multiple Cameras. If high-precision measurements were sacrificed due to speed, the FH Series returns your precision without increasing cycle time.Realtime Image Transfer

[Case 1] Perform Calculations for Multiple Cameras without Delay

Even when the measurement results of sequential operations are dependent on the speed of the independent action, parallel processing allows high speed performance without any dwell time. The measurement results from four cores can be easily calculated on one Controller to achieve continuous interaction without any special programming.

 

Measuring the Next Workpiece without Waiting Time


The lack of the ability for standard Vision Sensors to handle parallel processing creates waiting time everywhere. If the Machine cycle time cannot be increased, a Controller must be added for each process to perform parallel processing, increasing costs.Frequently Waiting for Processing with a Standard Vision Sensor

[Case 2] Machine Cycle Time Reduced to 1/4* of Previous Time

Four cores process triggers, so the trigger interval can be 1/4th* of previous models. 
* In-house comparison.

 

Multi-input Function (Continuous High-speed Image Capture)
Higher Speed from Advanced Image Capture and Parallel Measurements

Each camera has its own image buffer for storing image data that is separate from the main memory used for measurement processing. This allows for up to 256 frames of continuous high-speed image capture even while the main memory is processing measurement data.

 

[Case 3] Process Multiple Lines in Parallel without Any Waiting Time

Four controllers are compressed into one without increasing the line cycle time. You can greatly reduce costs for processes that involve many lines.

 

Fast Output of Measurement Results to Reduce Machine Cycle Time [FH]

EtherCAT Machine Control Network

EtherCAT is a high-speed open network that is ideal for Machine control. You can use EtherCAT to connect to NJ-series Machine Automation Controllers and motion control G5-series Servomotors and Servo Drives to increase the control speed over everyday communications protocols from workpiece detection to starting axis motion.

Positioning Solution That Eliminates Workpiece Dwell Time: Continuous Alignment (Patent Pending)

For a Machine that requires micron precision, one alignment is not always enough to obtain an acceptable error level, but executing multiple alignments greatly increases the processing time. OMRON provides control methods that eliminate workpiece dwell time, the main cause of increased processing time. Our Sysmac Automation Platform achieves high-speed, high-precision control that continuously detects workpiece positions and successively updates the travel distance to quickly approach the target position



 

Perform High-precision Machine Operation

The High-precision Object Detection Required for Positioning [FH] [FZ5]


Over the years, OMRON has perfected techniques to search for and match templates at high speed. From these techniques Shape Search Ⅲ provides advanced robustness, which is critical on FA sites. When measuring lamination of glass or other processes where the distance to the workpiece from the Camera varies, size differences and focal shifts can occur. Even in cases like this, the new Shape Search Ⅲ algorithm detects positions with limited error.Low-error Position Detection Even with Blurry Images



 

Stable Searching with Limited Error Even under Adverse Conditions

Stable searching is possible even under the following adverse conditions, which occur far too often in actual measurement applications.



 

Visualization of Comparisons Enables Easy Setup of High-precision Searching (Patent Pending)

Advanced searching is accompanied by many parameters that must be tuned to match the application. However, it is difficult for the person making the settings to see the internal process. Extensive time is required to make the most of tool performance. With Shape Search III, you can visualize comparisons between the model data and a part of the measurement object to easily see when comparisons are not matched well for the inspection. 
Visualization of the comparison level, allows for parameters to be adjusted simply to obtain the best performance.



 

Converting Measurement Results to Output User Units [FH] [FZ5]

Support for the Main Stages and Robots Used for 2D Positioning

The FH Controllers contain special setup displays for the stages and robots that are commonly used on FA sites. You just fill in the settings to easily output axis travel amounts for stages and robots.



 

Vision Master Calibration for High-precision Positioning Even with Normal Lenses

To perform high-precision positioning, the coordinate system must be accurately aligned between image processing and the stage or robot. Calibration is used to achieve this. Normally trial and error in the actual application environment is necessary, which requires experience in moving sampling points and a experience with the influence of minor tilt in the Camera installation, the influence of lens distortion, and other factors. With an FH Controller, all you need to do is set a minimum number of conditions. Movement patterns for the sampling points are automatically calculated to optimize the stage/robot axis travel ranges, imaging processing field of view, and other factors, and the required axis travel amounts are sent to the PLC. By moving the system according to the instructions, optimum sampling is achieved and the coordinate systems for image processing and the stage/robot are accurately aligned. Correction coefficients are simultaneously calculated for Camera tilt and lens distortion. If you use the calibration conversion parameters that are made with this function, you can easily achieve high-precision positioning even for normal lenses with high distortion rates.
