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

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:

“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.

5. How to check the mounting accuracy (with ACP

)

5.1. Preparation for the ACP adjustment

Scan camera is used as a reference camera when performing adjustment of the mounting

accuracy of the YS12 and YG12 models.

Mounting accuracy adjustment is performed by ACP using the ceramic chip.

The nozzle 301A (312A) and the 1005 chip component are normally used for performing the

adjustment.

If the machine is equipped with multi cameras (option), after performing the ACP adjustment with

multi camera using the 1005 chip adjustment, perform FAMF adjustment by mounting the Glass

QFP 68 pin with the 304A (315A) nozzle.

Please make sure to perform the following adjustments (work) before performing the ACP

adjustment (mounting accuracy adjustment) when installing or relocating a machine.

 System data back up

Make a backup copy of the system data before performing adjustment after installation of the machine,

or maintenance.

 Adjustment of the Y-axis dual drive offset

Correct the deviation between the Y1-axis motor and the Y2-axis motor caused by the relocation of the

machine. The adjustment does not need to be performed when the machine is not relocated or the

motor is not replaced.

 Adjustment of the “Orthogonalization level”

Correct the deviation in orthogonality of the axes after relocating a machine.

The adjustment does not need to be performed when the machine is not relocated or the Coord Macs

adjustment is performed.

 Adjustment of the “Brightness” (Illumination intensity of lighting) for each camera

Basically the adjustment needs to be performed when the installation environment of the machine is

changed. However if the adjustment is performed during maintenance, it affects the customer’s existing

production data. Please make sure to gain the customer’s approval before performing the adjustment.

 Adjustment of the “Fiducial Camera relative position” (Option)

Correct the deviation of the relative position between the reference camera and the sub camera caused

by the relocation of the machine.

ACP(Accuracy Calibration Program) is an adjustment function for the mounting accuracy used in Calib Sm, which is in

the [Utilities] for YAMAHA surface mounter; YG and YS series.
