Introduction

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.

If objects are moving, the position in the image of the characteristic that is to be measured will vary according to the timing of the trigger signal. The FQ Vision Sensor offers two different ways to adjust this position variation.

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.

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.

Trigger input Sensor

[Image] − [Trigger setup] − [Trigger delay]

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.

1 Change to the setup for to Sensor 1.

Timing of taking the image

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.

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.

5-1 Performing Test Measurements

After completing the settings in the [Image], [Inspect], and [In/Out] Tab Pages, move to the [Test] Tab Page. The displayed image is measured automatically. This is called a test measurement. A test measurement is used to verify that the settings that have been made will produce stable results and, if necessary, to fine-tune the settings. An overall judgement of all inspection items can be performed. Test measurements can be performed for through images (default) or saved images.

Performing Test Measurements with Samples

7-1 Changing the Scene to Change the Line Process

What Are Scenes?

With an FQ Vision Sensor, the inspection items that can be processed at the same time are registered as scenes. A command input from an external device or a touch panel operation can be used to select a certain scene. If a scene is registered for each type of measurement object or inspection, the line process can be changed simply by changing the scene when the measurement object or inspection changes.

Example:

Cap color (Inspection item 0: Color Data)

Label detection (Inspection item 1: Search)

These can be registered as one scene.

Text alignment (Inspection item 2: Edge Position)
