• 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!

• 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".

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.

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.

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.

The

calibration factors are determined and displayed

: Proceed as described in section

7.14, from

point 9 onwards

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).

➤ After "MEASURE MA ZERO POS." has been performed, the K-N-L is already installed as required for the

following procedure.

1. Select the main menu option "DETERMINE CAMERA OFFSET" and proceed as described in section 8.6

above, points 1 and 2. The PCB is conveyed to the center conveyor.

2. First the procedure for determining "CAMERA OFFSET" follows, the following screen display appears:

-FIX PLASTICINE ON PCB

- EXCHANGE ADH. CARTRIDGE FOR KLEBER-NULLPUNKT-LEHRE (K-N-L)

PLEASE PRESS <START> KEY

• The placement head is moved to the left (as seen in direction of PCB travel).

• Performance of the action: apply the plasticine to the

center of the PCB → remove the right-hand cartridge (= cartridge adjacent to fixed conveyor side) →

MA-install zero point insert for adhesive station II ("K-N-L" ) on the right → press the "Start"button.

3. After pressing the "Start" button the following display appears on the screen:

- ’TEACH’ K-N-L OVER PLASTICINE

- AFTER ’END’ AN IMPRESSION IN THE PLASTICINE IS CREATED

TEACHING IS ON, ’END’ TO FINISH

• Performance of the action: Teach the tip of the "K-N-L" (adhesive station zero point gauge) above

the plasticine → press the "END" button on the teach panel → the Z-axis is lowered once → an im-

pression in the plasticine is produced → the Z-axis is raised again.

4. The following screen display appears:

-’TEACH’ CAMERA INTO THE MIDDLE OF THE RIGHT IMPRESSION

TEACHING IS ON, ’END’ TO FINISH

• Performance of the action: Using the X-Y knobs of the teach panel, position the previously created

impression so that it is centered in relation to the crosshairs (screen of the evaluation unit) → press

"END" on the teach panel → the calibration factors determined are displayed and transferred to the

main memory after pressing "RETURN".

5. The measuring procedure for determining the "ADHESIVE NEEDLE OFFSET" follows automatically and

the following screen display appears:

- EXCHANGE LEFT ADH. CARTRIDGE FOR KLEBER-NULLPUNKT-LEHRE (K-N-L)

- ’TEACH’ K-N-L OVER PLASTICINE

PLEASE PRESS <START> KEY

• The placement head is moved to the left again (as seen in direction of PCB travel).

• Performance of the action (analogous to point 2 above): now install the K-N-L in place of the left car-

tridge → press the "Start" button.

6. The instructions how to proceed further are displayed:

- ’TEACH’ K-N-L OVER PLASTICINE

- AFTER ’END’ AN IMPRESSION IN THE PLASTICINE IS CREATED

TEACHING IS ON, ’END’ TO FINISH

• Performance of the action: Create new impression proceeding as described above under point 3!
