Creating and setting the data

Check the graphic alignment.

1. After closing the teach window, press the [Setup] button and select the [Setup] tab.

2. Press the [Visual Matching] button to open the screen for graphic alignment check.

3. The vision monitor in this screen shows an overlapped image of the board and mask, so check the

board and mask alignment.

1. Alignment coordinates

Select the coordinates where you want to check the board and mask alignment. These coordinates should first be set on

the [Print]-[Squeegee] tab screen. (See "5.1 Squeegee detail setting" in this chapter.)

2. Vision monitor

Shows an overlapped image of the board and mask.

The image can be enlarged from 1 to 16 times by pressing the enlarge [ + ] button, or reduced to 1/16 of the original

image by pressing the reduce [ - ] button. With the [Move] button depressed, you can move the image by dragging it with

the mouse.

3. Permeability

The transmittance of the board image and mask image can be adjusted with the slide bar or the arrow buttons.

4. [Teach] button

Opens the teach screen.

5. [Visual Matching] button

Opens the "Visual Matching" screen for making fine position alignments when needed. (See step 5.)

6. [Move Camera] button

Opens a screen for moving the vision camera unit.

7. [Move Table] button

Pressing this button moves the squeegee head to the inner end position and raises the board clamp table up to the back

surface of the mask. In this state, you can make a visual check of the board and mask alignment after pressing the

emergency stop button and then opening the upper door.

8. [Jump] button

Allows jumping to any desired row in the alignment coordinate list.

9. [Trace] button

Pressing the [Trace] button displays an image of the currently selected alignment coordinates. Pressing the [Trace

Previous] button displays an image of the alignment coordinates one row up from the currently selected coordinates.

Pressing the [Trace Next] button displays an image of the alignment coordinates one row down.

Creating and setting the data

Press the [Visual Matching] button.

If a position offset (deviation) is found by graphic or visual alignment, you can adjust it in the "Visual

Matching" screen that appears when you press the [Visual Matching] button. (Skip this step when no

position offset is found.)

1. While moving the image in the XY directions using the [Arrow] buttons, make fine-alignments until

position offsets are no longer seen. The values in the "Offset X" and "Offset Y" boxes just above the

[Arrow] buttons change as you move the image.

2. After aligning the position, press the [Offset Set] button.

The number "1" appears in the "Count" box.

3. When you want to make alignments at other coordinates, select the coordinates and repeat the

same procedure.

The number in the "Count" box increments each time an alignment is made ([Offset Set] button is

pressed).

When finished making alignments at the necessary coordinates, press the [Offset

Total Teach] button.

The offset amount for the entire board is then calculated based on the adjusted offset values and the

results displayed in the "Visual Matching Offset X", "Visual Matching Offset Y" and "Visual Matching Offset

R" boxes in the lower part of the screen.

Press the [Offset Clear] button if you want to clear the offset amount and retry from the beginning.

Press the [OK] button to update the offset amount.

The offset amount calculated here will be entered in the "F. Mask Offset XYR" and "B. Mask Offset XYR" in

the squeegee data. If you do not want to update the offset amount, press the [Cancel] button.

NOTE

If you want to align the printing position with a point other than the center of the board in order to compensate for

board or mask expansion, make graphic alignments after updating the offset by adjusting the center position and

rotational deviations.

Close the screen for graphic alignment.

After closing the screen, follow the message that appears and unload the board.

9. Making a test print

When visual alignment on the created data has been made, make a test print before starting board

production, to check the printing conditions and accuracy and make necessary adjustments. In test print, we

recommend covering the board with a transparent sheet (option) to protect the board just as with the rolling

operation.

Note

When printing with newly created board data, always make a test print before starting production to check the

printing conditions and accuracy. Even when printing with board data you have used, we recommend making a test

print before beginning daily work.

Press the [Test Print] button on the Setup screen.

Follow the message on the screen to load a board on the conveyor.

This step is skipped when a board has already been clamped on the conveyor.

After the board has been clamped on the conveyor, the board fiducial mark and mask fiducial mark will

be automatically recognized. (This mark recognition is skipped if not using the fiducial mark function.)
