# Click Step Reference Image

• Click RUN to view the program

and to observe the results of the

Positional Checking.

As the program runs, the following occurs:

• A window opens to show green or red dots (for this example, in a

grid of two columns and threerows), indicating whether a deposit

(the white dot) passes (green) or fails (red):

- Pass: The deposit is within both Offset X and Offset Y values.

- Fail: The deposit is outside one or both of the Offset X / OffsetY

values.

NOTES:

- The window is named A (from step 2 on page32).

- In this example, all dots are green because all white dots are

within the speciﬁed X and Y offsets.

• If a dot fails, the system takes the action speciﬁed by the Stop,

Skip, Pause, Ask parameter (Skip, in this example). Refer to “Arrow

Check Point” on page71 for details.

• Screen captures of both passed and failed dots are saved as

images and named automatically.

NOTE: If the screen captures are not automatically saved, ensure

that the Save Images checkbox in System Setup is selected. Refer

to “Setting Up the System to Save Images” on page9 for

details.

12 • To view the images of the marks,

use the ﬁle explorer application to

navigate to D:\AOIIMAGE:

- Dots that passed (green) are

saved in the OK folder.

- Dots that did not pass (red) are

saved in the NG folder.

Intersect Line Example

Intersect Line is an OptiSureAOI feature that allows you to create mark images for a workpiece that does not have

any obvious features. To do so, you create marks using the corners and edges of the workpiece. This function also

works for creating marks for an R-shaped area.

NOTE: If the rounded corners are too large to use Intersect Line, try using the Edge Adjust command. Refer to the

operating manual for details.

PREREQUISITES

 To learn how to use this feature, draw a large black rectangle with rounded corners on a sheet of white paper

and use it as a workpiece template.

To Create an Intersect Line Mark Image

# Click Step Reference Image

> >

• Click CAMERA > LENS.

• Select the GRAY IMAGE checkbox.

NOTE: Selecting Gray image is

optional, but doing so provides

a sharper image and also slightly

zooms out the image.

2 • Jog the camera to the top left

corner of the workpiece template,

positioning the crosshairs along the

top and left sides of the template.

• Click SET MARK, then drag to

position the red box at the top left

corner of the workpiece template.

NOTE: If needed, refer to the robot

operating manual for a detailed

procedure on how to create a mark.
