1-1 FQ-series Vision Sensors

FQ-series Vision Sensors are real-color Vision Sensors with integrated processing. Once configured, they are used stand-alone for quality inspection of presence, position, and other product characteristics. To set up or monitor the sensors, either the touch screen based console 'Touch Finder' or a 'PC Tool' can be used.

Setup, Image Confirmation, and Logging Tools

Touch Finder

FQ Vision Sensor

Used to check images and set the judgement parameters. It can also be used to save measurement results and check status during operation.

PC Tool

Includes the camera, lighting, measurement processor, and I/O functions. After the Sensor has been set up, it can be operated alone to perform measurements without the Touch Finder or PC Tool.

The same functions as those that are provided by the Touch Finder can be performed from a computer. The PC Tool is available free of charge.

FQ-series Vision Sensors are available in two different models. The differences are given in the following table.

HDR Function

The HDR function is used for objects that have a large difference between light and dark areas. For this kind of object, clear images cannot be achieved with the standard brightness setting. The HDR function combines several images of different brightnesses (exposure times) so that the resulting image has a lower degree of contrast and can be measured stably for the desired characteristic.

image is input, to synchronize the timing of image input with the speed of the moving objects.

Position Compensation

The FQ Vision Sensor performs measurements in measurement regions that are set to a fixed shape and position by the operator. A measurement is not performed properly if the object is not positioned inside this measurement region (e.g., the result will be NG even if the object is OK). In machines in which the position of the object varies for each image, stable measurements would be impossible. To cope this problem, the Position Compensation function aligns the whole image so that the object to be measured is moved exactly to the measurement region.

Reference position (as set by the operator)

The measurement object is properly within the measurement region.

Measures to Stabilize Position Correction

• Low Mark Contrast and Inconsistent Correlations

Areas with high contrast are registered as model registration sections. The adjustment procedure is the same as for the search function. Or, adjust the brightness to increase the contrast of the mark.

Making dark images brighter: p. 38

• Inconsistent Marks and Inconsistent Correlations

Inconsistent portions can be masked so that are omitted from matching.

Operating procedures for other functions are basically the same as those for searching. Refer to the following information.

Unstable search results: p. 54

Increasing the Speed of Position Compensation

The following method can be used to reduce processing time.

• Reduce the range in which searches are performed for the model.

Operating procedures for other functions are basically the same as those for searching. Refer to the following information.

Changing the measurement region: p. 57

Adjusting the Image Timing

The internal timing for taking an image can be set to be delayed in relation to the external trigger signal. This can be used to adjust the object position in the image, e.g., if an external trigger sensor is used. If the object position still varies in the image the Position Compensation function must also be used.

Delay time

Delay from when the trigger is input until when Sensor input is started.

3-4 Preventing Mutual Interference of Multiple Sensors

When the same trigger signal is input to multiple Sensors, the lighting from one Sensor may affect the measurements of the other Sensors. This is called mutual interference. This kind of interference can be prevented offsetting the image input timing of each Sensor from when the trigger signal is received. Example: A trigger (i.e., the TRIG signal) is input to Sensor 0 and Sensor 1 at the same time.

Sensor 0

Trigger Sensor

Sensor 1

Sensor 0

Sensor 1

Sensor 0 immediately begins image input when the trigger is input. Sensor 1 begins image input after the specified time has passed.

Important

• The delay time for preventing mutual interference must be longer than the shutter time. When the lighting built into the Sensor is used, the shutter time is 4 ms max. Therefore make the delay at least 4 ms.

Unstable Search Results

Inclined Measurement Objects

Adjust the [Angle range] parameter to increase the range in which a search is made for the model. The Search inspection item judges whether an image is OK or NG according to the correlation with a previously registered image pattern. For this reason, if the object is at an angle, the correlation is reduced and the image may be judged as NG. To achieve an OK judgement for the same image pattern even when the object is at an angle, the rotation range must be widened.

4-9 Calculations and Judgements Using Inspection Item Data

You can set inspection item judgement results and measurement data with the Calculation menu command to use them in basic arithmetic operations and functions. The judgement results of the calculations are reflected in the overall judgement.

Calculation

Use the Calculation menu command to set the calculation expressions and the judgement parameters for the calculation results.

Expression

You can get up to 32 expressions. You can also combine expressions. You can use the following values in calculations.

• Inspection item data (measurement data, reference values, and judgement results)

•Constants

• Other calculation results

Judgement

Upper and lower limit values are used for the judgement of calculation results (D0 to D31). Each calculation judgement result (J0 to J31) is turned ON if the result falls within the upper and lower limits. The OR logic of these results will be the overall judgement result JG.

Until you have saved your settings explicitly to the memory in the FQ Vision Sensor, the settings are only stored temporarily. They will be lost if the power is turned OFF. Execute [Save data] after you have finished making your settings. The FQ Vision Sensor will remind you to do so with a message if you switch from Setup Mode to Run Mode. You can use this feature to keep the previous settings and discard the new settings if desired, but keep in mind that all settings that are not saved explicitly are replaced by the settings that are stored in the memory of the FQ Vision Sensor the next time you turn ON the FQ Vision Sensor.

Important

Do not turn the power supply OFF while data is being saved. The data that is being saved may become corrupted.
