3.5.3 Calibrating the multi-vision camera scale
The multi-vision camera scale represents an actual measurement (in
microns) equivalent to one pixel. This scale must be calibrated correctly
for accurate recognition of components.
To calibrate the camera scale, you will need an SOP or QFP of known size.
When you run the adjustment utility described below, the camera scale is
automatically calibrated and the XY positions and installation angle R of
the camera are also adjusted at the same time.
1 Prepare a component to be used as a reference.
Use a relatively large, popular SOP or QFP of known size which is
registered in the component database. If using tape feeder components, set
the tape feeder on the feeder plate in advance.
Reference
YAMAHA uses a glass QFP with minimal warp and distortion, specially designed for
adjustment work. To make more accurate adjustments, we recommend using this glass
QFP (sold separately).
2 Edit “Search Area mm” in the component data.
Data registered in the database as a number larger than No.500 cannot be
edited due to write-protection. Make a copy of the data using a number
smaller than No.500, then edit this data. For instance, the following steps
are explained for cases where SOP data is copied onto registration No. 2.
If using a glass QFP (database No. 996), skip this step.
1. Open component database and line up the cursor with component No.
2.
2. Press the [TAB] and [F4] keys to switch the sub-window to “VISION
INFO.” and change the Search Area value to “9.99” (maximum setting).
Since the camera scale is measured while moving the component
slightly, this change compensates for that movement.

3. Press the [F4] key to switch the sub-window to “BASIC INFO.” and
change the Comp. Package parameter to “Tray” if you want to attach
the component to the nozzle by hand during this adjustment. Leave this
parameter unchanged (“Tape” ) when you are going to use a tape
feeder.

3 Press the emergency stop button, then attach an appropri-
ate nozzle to Head 1.
Use a Type 73A or 74A nozzle for this adjustment. (If using a glass QFP,
attach Type 74A.)
4 Run the Adjust Assistant to check that the component is
recognized.
1. Cancel emergency stop and enter the Adjust Assistant mode.
2. Run the “PICK UP COMP” “VISION TEST” commands and, if
necessary, adjust the parameter values. (For details on the Adjust Assistant,
refer to the mounter operation manual.) You can leave the component
attached to the nozzle even after finishing the Adjust Assistant.
5 Save the edited data.
Press the [ESC] key twice, then select <C0 SAVE & EXIT> and press the
[ENTER] key.
6 Run the “Multi Camera” − “Camera Scale” command.
1. Select <3/3/B1 ADJUST TARGET> − ”Multi Camera” − “Camera Scale”
and press the [ENTER] key.
2. Select the conveyor table and the camera No. by pressing the [ENTER]
key.
The A-table multi-vision camera is designated “Cam. 5” and the B-table
multi-vision camera “Cam. 6”.

Reference
When you are using a tape feeder, the feeder set No. input box appears, so follow the
message on the screen. In this case, the component is automatically picked up and Steps 9
to 10 are skipped.
