4.5.4.2 Teaching a mark

The system teaches information required to recognize a mark. To start teaching a mark, move

the cursor to the mark name of data to be taught, and then select the “Teaching” button in the

Operation area. Note that you have to enter the XY coordinates of a mark with the Program

Editor in advance.

When you select the “Teaching” button, the camera moves to the XY coordinates of the entered

mark position, and then the image shot with the selected camera and the scale frame (rectangular

frame) are displayed on the screen.

1) Device Select

When you press the camera button shown in the “Device Select” column, you can reverse

the polarity (brightness).

If a mark looks black against the board, press the camera button so that the mark can look

white.

Reverse of the mark with the camera button is effective only when you enter the scale

frame.

2) Light pattern setting

If a mark can be recognized according to the standard setting of the light (that is, when the

<Standard> button is selected), you do not have to set this item.

Set this menu item only when the system does not recognize a mark stably.

Light pattern Processing

Standard

Use this button to recognize a normal board mark.

Resist/Cover Film

Use this button when the mark reflects the standard light in an undesirable manner and

a mark cannot be recognized stably because there is a resist or a cover film on a mark.

User defined

Use this button to set the light amount of the vertical light and that of the inclined light

directly when a mark reflects the light in an undesirable manner in the two cases above

and the mark cannot be recognized stably.

When you select the <User defined> button, enter the light value directly.

Select the <Vertical> button or the <Inclined> button, and then enter a value in the edit box,

or use the <+> button and/or the <-> button to change the entered value.

3) Move Speed

You can select the speed at which the camera moves.

When you touch the image shot with the camera, the XY-axes move in eight directions.

While you are touching the image, the axes continue to move.

CAUTION

To avoid a risk of injury, do not put your hands inside the machine

or move your face or head close the machine while the system is

teaching data.

(1) Teaching a board mark

To teach a board mark, follow the procedure below after teaching starts.

1) Setting the scale frame

Align the upper side and the left side of the scale frame with the upper edge and the

left edge of the mark, and then select the <OK> button to validate these two sides.

After validating two sides, align the lower side and the right side of the scale frame with

the lower edge and the right edge of the mark in the same manner, and then select the

<OK> button to validate these two sides.

At this point, the system automatically recognizes the mark, and obtains data

necessary for correction.

2) Setting the noise cut level

The system automatically obtains the noise cut level around the mark, and then

displays it.

Adjust the noise cut level with pressing the upper/lower sides of the frame so that the

mark can be displayed clearly and the noise around the mark can be reduced as much

as possible.

After adjustment, press the <OK> button.

The image shot with the camera and the scale frame are displayed

on the screen.

First, set the upper side and the left side of the scale frame.

Adjust these sides so that they match the upper edge and the left

edge of the mark respectively.

After adjustment, press the <OK> button.

In the same manner, set the lower side and the right side of the

scale frame.

After adjustment, press the <OK> button.
