1.2.10.8. R-Axis Offset Calibration

If the recognized angle and placement angle of the R axis are different, the R axis

error cannot be compensated through the Vision. Therefore, the placement accuracy

decreases.

Therefore, perform R axis offset calibration to minimize such error by

compensating an approximate value with the R axis motion data.

The CNT20 nozzle must be used to perform this calibration.

The following is the procedure to calibrate the ‘R-Axis Offset’:

1. Click the <Nozzle Prepare> button and insert the CNT20 nozzle into the No. 1

hole of the ANC manually.

If the <12. R-Axis 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 <12. R-Axis 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 home position on the machine,

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 “Z Axis moving down…. Please Wait for a Moment.” appears,

and the dialog box asking whether to skip the calibration of Head1 is displayed.

Click “Yes (Y)” to skip or click “No (N)” to proceed with the calibration. And

then click the <Next> button.

6. The message “Move To Center Position of Calibration Tool. To Move, Click

[Next].” appears. appears in the message window. Click the <Next> button to

move the head assembly to the calibration tool position on the ANC.

7. The message “Calibration is Prepared. To Calibrate, Click [Next]” appears. At

this time, At this time select the ‘Fly Cam1‘ in the <Target Camera> combo box

and,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. 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.

9. For Head #2 ~ 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.

The measurement result can be confirmed in the R Axis dialog box.
