3.11.2 Calibration of the IC-Nozzle Changer
●
To calibrate the IC-nozzle changer, select the
Noz.changer IC-head
option from the "Nozzle changer"
menu and press the RETURN key.
The "Noz.changer IC-head" menu is displayed on the screen.
Overview of the Functions:
-
Cal.noz.chang.compl. to determine the x and y-values for each nozzle changer compartment
-
Calibr. fiducial 1 to calibrate reference marking "1" (marking "1" is close to the PCB conveyor)
-
Calibr. fiducial 2 to calibrate reference marking "2" (marking "2" is close to the component table)
-
Disp. nozzle positions to display the values determined for each nozzle changer compartment
-
Pick up nozzle to pick up the nozzle from the selected nozzle changer compartment
-
Return nozzle to return the nozzle to the selected nozzle changer compartment
(determination of the z-height)
-
Garage [1..20] to select the nozzle changer compartment
-
Positions to display the pick-up positions.
(The data can be edited, if required.)
NOTE
For the calibration of the IC-nozzle changer it is necessary that a magazine is present in the 1st and 4th
magazine location of the nozzle changer.
For the determination of the nozzle positions, reference marking "1" and
reference marking "2" must be
calibrated.
●
Select the
Cal.noz.chang.compl.
function and press the RETURN key.
The PCB camera approaches the measuring holes (reference markings "1" and "2") in the nozzle changer
and calculates from the positions determined the x and y-values for each nozzle changer compartment.
●
Select the
Disp. nozzle positions
function and press the RETURN key.
A comparison of the setpoint values versus the actually determined values in x and y-direction is displayed
on the screen for each selected nozzle changer compartment.
●
If you wish, for example, to calibrate reference marking "1", select the
Calibr. fiducial 1
function and press
the RETURN key.
The PCB camera approaches reference marking "1" (measuring hole 1) in the nozzle changer and calcu-
lates, from the values determined, the nozzle pick-up position.

●
To determine the pick-up height (z-height), select the
Return nozzle
function and press the RETURN key.
The nozzle is returned to the nozzle changer compartment.
●
Next, select the
Pick up nozzle
function and press the RETURN key.
The nozzle is picked up.
If the nozzle is not properly returned and then picked up again, you can change the values for the pick-up
positions.
●
Select the
Positions
menu item. The "Positions" input screen opens.
●
Change the values, as required, and confirm your entries by pressing the RETURN key.
●
Press the ESC key to return to the "*Noz.changer IC-head" menu.
●
To verify the changed positions, select the
Return nozzle
function and press the RETURN key. The
nozzle is returned to the nozzle changer compartment.
●
Next, select the
Pick up nozzle
function and press the RETURN key.
The nozzle is picked up.
(The steps described above may have to be repeated if the nozzle is, once more, not properly returned
and picked up.)
NOTE
The values for the "pick-up angle" and the "z-position" can be saved to the "REAL.MA" file via the
File
Manager
-->
Store MA-file
main menu option (see section 1.3).
●
Press the ESC key three times to return to the SITEST main menu.

3.12 Saving the Calibration Data
●
To save the values determined, select from the SITEST main menu the File Manager option and press the
RETURN key. The "File Manager" menu opens (see section 1.3).
●
Select the Store MA-file function and press the RETURN key.
The values determined are saved to the "REAL.MA" file.
●
Press the ESC key to return to the SITEST main menu.
NOTE
Only
the values for "Zero point cor. value", "Minimal position" and "Maximal position" that were modified in
the "Positions" input menu can be saved with the aid of the main menu option File Manager --> Store
MA-file. All other modified axis data cannot
be saved. They will be reset to the original values upon exiting
from the SITEST program
.
