1.2.10.7. Fly to Fix Camera & Fly Runout Offset Calibration
Calibrates the relation between the Fly camera and Fix camera. The calibration is
performed to compensate the offset that occurs due to the difference between the
‘part-alignment height’ and placement height when placing the part after part-
recognition by the fly-camera.
The offset that occurs this time is caused by the run-out, bending of an axis, etc.
Perform compensation of the value at the recognition height of the fly camera and
fiducial camera, which are the same as the placement height.
In order to perform this calibration, the ‘Fly-Camera Offset Calibration’, ‘Fix-
Camera Scale Calibration’ and ‘Head Offset Calibration’ must be performed first
and the CNT20 nozzle must be used.
The following is the procedure to calibrate the ‘Fly to Fix Offset’.
1. Click the <Nozzle Prepare> button and insert the CNT20 nozzle into the No. 1
hole of the ANC manually.
If the <11. Fly to Fix Offset> is clicked after selecting the <Automatic Next>
check box, calibration is performed for the selected gantry automatically.
If calibration is performed after selecting the <No Real Motion [Manual]>
check box, the nozzle is inserted into each head manually. Click the <Next>
button to move onto the next step.
If calibration is performed without selecting either the <Automatic> check box
or <Manual> check box, the nozzle is changed automatically for the currently
selected nozzle. Click the <Next> button to move onto the next step.
2. If the <11. Fly to Fix Offset> button is selected, the message “First, We must
Put all Nozzles From Heads on Manually. To Move down Z Axis, Click [Next]”
appears. Click the <Next> button to move down the Z-axis of the head in order
to manually move all nozzles inserted in the nozzle-holder of the head.
3. Then, after the head assembly moves to the designated position, move all Z-
axes down. At this time, remove all inserted nozzles manually.
4. Then the message “Next Attach the Calibration Tool to Head 1. Click [Next]
for Moving Down Head. After Moving, Attach the Tool to Head Manually”
appears. Click the <Next> button after inserting the CNT20 nozzle in the
nozzle-holder of Head #1 manually.
5. The message “Move To Center Position of [Fix1] Camera. To Move, Click
[Next]” appears. Click the <Next> button to move the head assembly to the
center of the Fix1-Camera. At this time, select the ‘Fix Cam1’ in the <Target
Camera> combo box. Click the <Light…> button and adjust the brightness of
the light in the ‘Light Control’ dialog box so that the fiducial mark on the
CNT20 nozzle that is seen in the ‘SMVision’ window can be seen clearly.
6. Then the message “Up to Align Height and Mirror Close, Click [Next]” appears.
Click the <Next> button.
7. Next, Head 1 moves up to the align height of the Fly Camera and the mirror is
closed. Then the message, “Calibration is Prepared. To Calibrate, Click [Next]”
is displayed in the message window. At this time select the ‘Fly Cam1‘ in the
<Target Camera> combo box and, in the ‘Light Control‘ dialog box, adjust the
brightness of the lighting so that the ‘Fiducial Mark’ on the CNT20 nozzle can
be clearly seen in the ‘SMVision ‘ window. Then click the <Next> button.
8. The calibration is performed automatically. If it is completed, the calibration
result is displayed as shown in the following figure. Click the <Next> button.
9. From Head #2 to Head #6, perform calibration in the same manner as it was
performed for Head #1.
10. If the calibration procedure is completed for all heads normally, the result is
displayed as shown in the following figure. Click the <Update> button to apply
the calibration value.
The measurement result can be confirmed in the Fly-Fix Offset dialogbox.
