➤ If NO is selected (head is not in top position): Display of the main menu → error in the compressed air
branch of the dispensing stroke:
Switch off machine → eliminate the malfunction (compressed air branch / pressure spring / solenoid valve).
➤ If YES is selected: Gantry reference run (!) is performed → display of the main menu of Adhesive
Station II (see Fig. 1.2). Start calibration with "CHECK X-/Y AXIS ADJUSTMENT".
8.1 EDIT MENU
Information about the general procedure in the EDIT MENU is contained in section 7.1.1.
• After changing the MA-zero point correction values, the manually determined "DETERMINE MAX. AND
MIN. Z-AXES TRAVEL RANGES" (see section 7.4) are to be entered in the EDIT MENU.
8.2 CHECK AXIS ADJUSTMENT
The X and Y-axis adjustment is always to be tested before the first measuring routine is carried out.
• Perform the procedure analogously to section 7.2.
8.3 MEASURING MACHINE ZERO POSITION
Tools and testing aids required:
• MA-zero point insert for Adhesive Station II, item no. 02102407 *
• New MA-zero gauge (with 2 holes), item no. 00120060
• Spherical hexagon socket screw key M3
* referred to as "adhesive zero gauge" or "K-N-L" on the screen!
1. Select "MEASURE MACHINE ZERO POSITION" → press the "Start" button → the "Bero movable table
side" is approached and the adhesive dispenser head positioned to the left in service position → the following
screen display appears:
EXCHANGE RIGHT ADH. CARTRIDGE FOR KLEBER-NULLPUNKT-LEHRE (K-N-L)
MEASURE MACHINE ZERO POSITION
INSTALL THE MACHINE ZERO POINT
PLEASE PRESS <START> KEY
• Performance of the action: Open the machine base door at the compressed air unit → reduce the
compressed air supply for the stroke cylinders (dispensing stroke) to approx. 3 bar (to preclude any
distortions upon measuring the MA-zero point) → close machine base door → open protective cover
→ remove the right adhesive cartridge (= cartridge closest to the fixed conveyor side) → in its place in-
stall the adhesive zero point insert → install gauge on fixed conveyor side and secure with screws →
close protective cover → press the "Start" button.
2. The K-N-L enters the large hole. Thereafter the following query is displayed:

• Check the position of the K-N-L and press the appropriate function key YES / NO.
➤ If YES is pressed: The hole is measured → display of the deviation (see point 3).
➤ If NO is pressed: The teach mode is activated and the following screen display appears:
TEACH ADH. NOZZLE INTO MACHINE ZERO POSITION
USE TEACH-PANEL
• Performance of the action: Using the buttons on the teach panel insert the nozzle (K-N-L) into the large
hole (for details refer to section 7.3 from point 5 onwards) → press the "END" button on the teach panel.
3. The values determined are displayed:
DEVIATION OF MEASURED MACHINE ZERO POSITION [ X,Y ] -1 1 DIGIT
CORRECTION VALUES (X,Y) -23133 -3475
CORRECT MACHINE ZERO POSITION ?
• The new correction values are always to be accepted by pressing the function key YES. The gantry
axes are thus re-initialized and the new correction values adopted. The acceptance of the new values
is a precondition for all further calibrations.
4. The following query is displayed on the screen:
IS NOZZLE IN SMALL MEASURING HOLE (3.5MM)
• The further procedure is the same as described in section 7.3, from point 9 onwards.
Final actions are as follows: Remove MA-zero point (MA-zero point gauge) → the MA-zero point insert
remains installed in the adhesive dispenser head for performance of the measuring routine "DETER-
MINE CALIBRATION FACTORS OF HEAD CAMERA" → close protective cover → press the "Start"
button → display of the main menu → select "STORING"
NOTE
If you do not accept the MA-zero point, i.e. if you are terminating the AutoCal procedure at this stage, you
must reinstall the adhesive cartridges and adjust the pressure the dispensing stroke at 3.5 bar!
8.4 DETERMINE PCB EDGE FIXED TABLE
• Carry out the procedure as described for the HS-180 in section 7.8. The "TRACK MEASURING MENU"
requirement is dispensed with for Adhesive Station II. Subsequently continue with section 8.6. Reason:
"CALIBRATION FACTORS..." must be performed before the glass mapping procedure!.
8.5 MAPPING MENU (GLASS MAPPING)
Glass mapping on Adhesive Station II is identical to the glass mapping procedure on HS-180 placement stations.
• First determine the calibration factors of the head camera and the camera offset incl. dispensing needle
offset.
• Remove the MA-zero point insert (K-N-L) and adhesive cartridges before starting the glass mapping pro-
cedure (safety precaution to protect the glass plate)!
• Proceed with the glass mapping procedure exactly as described for the HS-180 in section 7.10.

8.6 DETERMINE CALIBRATION FACTORS OF HEAD CAMERA
➤ This measuring routine is -together with "DETERMINE CAMERA OFFSET" - a precondition for "glass
mapping" on HS-180 machines (placement station and adhesive station II).

. After this main menu option is selected, the ICOS computer is synchronized, the fiducial data are
loaded and sent to the ICOS computer the display for
conveyor width adjustment
appears
:
Adjust conveyor to the PCB width subsequently used (see section 5.1.19) → select "END".
2.
The following screen display appears:
PLEASE PLACE A PC BOARD OVER THE SENSOR OF THE INPUT CONVEYOR
• Place the PCB above the light barrier of the input conveyor. The PCB is conveyed to the center conveyor.
3.
A
graphical display
of the position of the calibration plate and the following prompt are displayed:
PLACE CALIBRATION PART ON MOTHERBOARD
PLEASE PRESS <START> KEY
•
Performance of the action:
Open the protective cover → take a hold of the calibration plate by the outer
edges only (!)→ check the calibration plate for oxidation or contamination: All metal surfaces must have the
same coloring → replace the calibration plate with a new one, if necessary → place the calibration plate
ex-
actly
in the upper right corner of the PCB (as shown on the screen) → check the position of the
points
rela-
tive to the direction of travel → close protective cover → switch on the control → press the "Start" button.
4.
The graphic is cleared from the screen and the following display:
’TEACH’ CAMERA INTO THE MIDDLE OF THE FIDUCIAL
USE TEACH-PANEL
TEACHING IS ON, ’END’ TO FINISH
•
Performance of the action:
"Teach" the PCB camera in
X-Y
-direction until the crosshairs on the scre-
en of the evaluation unit are positioned centrally with respect to the image of the calibration plate →
press "END" on the teach panel.
5.
The
calibration factors are determined and displayed
: Proceed as described in section
7.14, from
point 9 onwards
.
6.
If the measurement was
successful
and after pressing "RETURN" (= transfer to the main memory), the
following display appears on the screen:
PLEASE REMOVE PCB FROM OUTP. CONV.
•
Performance of the action:
Remove the PCB incl. the calibration plate from the output conveyor →
display of the main menu → transfer the values determined to the work diskette by selecting
"STORING"
.
• Continue with "DETERMINE CAMERA OFFSET".
8.7 DETERMINE CAMERA OFFSET and ADHESIVE NEEDLE OFFSET
➤ This measuring routine is used to determine the camera and dispensing needle offsets.
➤ Prerequisite for this routine: The
calibration factors
of the head camera must have already been deter-
mined (see section 8.6).
