26/60
If the data is corrected, please perform measurement again after saving the Coord Macs data.
Check if the variation of the perpendicularity falls within the specification, save the data and fill in
the value on the check sheet.
[If the mark recognition cannot be performed successfully]
Check if the board is clamped properly and the mark is not contaminated.
Check if the mark can be recognized by selecting the mark information “NO.1
Glass_0.5_Circle “ and performing recognition check on the “Mark Adjust” screen.

4.7. How to adjust the “Fiducial camera relative position”(Option)
YS12 and YG12 models are equipped with two fiducial cameras at the user’s option.
By using the sub fiducial camera (mounted on the left side of the head), the pick up position of the
components that cannot be recognized with the reference camera (mounted on the right side of
the head) can be recognized and the coordinate can be precisely obtained.
The relative position of the reference camera and the sub camera is accurately adjusted by the
utility.
Normally, the position of the sub camera is adjusted based on the position of the reference camera.
The position coordinate of the reference camera is adjusted by the ACP adjustment.
[Tools required for adjustment]
Please use either of the following boards.
KM0-M8810-400 GLASS PCB ASSY.4 ACP class board
KM0-M8810-100 GLASS PCB ASSY.1 AMF glass board
Table 18
4.7.1. Adjustment procedure
1. Select the “Fiducial camera relative position”.
Click on the [Fiducial Camera relative Pos] button on the main menu of CalibSm.
Figure 36
2.
Check the camera number.
Check if “Digital 2” is selected from the dropdown list of the camera number.
Set which fiducial mark of the board is to be
used. Normally, it is set automatically depends
on the conveyor direction.
- From right to left: 2
- From left to right: 1

Note:
<When the reference camera is replaced>
“Digital 2” indicates sub camera. When the reference camera is replaced and the coordinate of the
reference camera is adjusted, change the camera number to “Digital 1” and perform adjustment
based on the coordinate of the sub camera.
3. Trace the mark.
Set the glass board on the conveyor and click on the [Trace] button.
The head moves to the position where the mark (Φ0.5 mark on the board) can be
recognized.
4. Mark recognition test
Move the specified camera to the center of the mark to perform mark recognition test. If the
recognition error occurs, investigate the cause of the problem on the [Mark Adj] screen and
take proper measures, then perform recognition test again.
Figure 37
5. Click on the [Execute] button.
Click on the [Execute] button to recognize the same mark with the two cameras.
6. Save the measured data.
When the adjustment is completed, the dialog box appears asking you to save the data.
Figure 38
Check if the camera number is correct and the variation is normal, and then save the data.
Note:
- The [Switch camera] button is not normally used in this utility. The coordinate of the selected
camera is adjusted based on the coordinate of the other (adjusted) camera. The coordinate
adjustment of the two cameras cannot be performed at the same time with this utility.
- If the positional relation of the two cameras is not changed mechanically (including lens, CCD
and so on), the adjustment does not need to be performed.
- When the coordinate of the reference camera is changed in the ACP adjustment, the
coordinate of the sub camera is changed as well.
