NOTE

If the AutoCal program continued with the next nozzle position on account of a measuring error of a Z-

position, the reason for this (defective nozzle / incorrect angle offset of the D-axis) must be eliminated

and the measurement of the positions must be repeated.

If you perform the "nozzle endurance run" following the determination of the nozzle positions, the nozzle

insert remains installed. Just press the "START" button.

• Performance of the action:

Open the protective cover → remove nozzle top part ( = nozzle insert) → install steel nozzle (= normal

nozzle) and secure with knurled nut → close protective cover → switch on the control → press the

"START" button → placement head moves to the waiting position → display of the main menu.

15. Select "STORING" to transfer the values to the work diskette.

— Annotation to the individual check: Prior to starting the station software the reference status of the

nozzle changer HS-180 must be established (see section 10.1.4).

7.12.2 MEASURE ONE SINGLE NOZZLE

This routine is only designed for checking and measuring the X,Y and Z-positions of one single, selectable

nozzle, e.g. in the event that for the nozzle concerned an error message has just been released when it was

picked up or returned during the placement cycle for this nozzle.

➤ Within the scope of the Routine Check all positions are always determined (see section above)!

1. After selecting "MEASURE ONE SINGLE NOZZLE" the graphical display (top view of

nozzle changer HS-180) for inserting the measuring socket and the following text are displayed:

KEY IN THE NOZZLE NUMBER: _1

• Enter the no. of the nozzle to be measured (= location no., see graphics) on the keyboard and con-

firm by pressing "RETURN". The AutoCal program performs a check as to whether the no. entered lies

within the acceptable range. The entry can be aborted by pressing the "Abort" button.

• After entering a valid no., the X, Y and Z-positions of this nozzle are measured. The procedure is simi-

lar to that of "MEASURE NOZZLE POSITIONS" (see section 12.1).

➤ For the determination of the X,Y-position the measuring socket must be inserted in the selected location.

➤ For the determination of the Z-position the correct nozzle (the correct nozzle type) must be inserted in

the selected location: The assignment of nozzle type/location no. can be viewed on the line computer

(see CAUTION text on the preceding page!).

7.12.3 Nozzle Endurance Run

This menu option serves to check the pick-up and depositing operation (for the Routine Check it is

recommended

➤

Prerequisite

for the performance is, among others, (see also chap. 6) that the "ANGLE OFFSET D-AXIS"

has already been determined and been transferred to the MA_DATEI (see "EXECUTE NEXT 4 POINTS").

Testing aids:

• All nozzle types/sizes for setting up in the nozzle changer (to be viewed on the line computer)

• Nozzle top part ( = nozzle insert), item no. 00302566

From the main menu select "NOZZLE ENDUR. RUN". The following display appears on the screen.

PLEASE PROVIDE NOZZLE CHANGER WITH NOZZLES AND

PUT NOZZLE INTO HEAD

PLEASE PRESS <START> KEY

•

Performance of the action:

See "MEASURE NOZZLE POSITIONS", point 9.

After pressing the "START" button the

graphical display

of the nozzle changer with marked

current nozzle position and the following text are displayed:

PRESS ANY KEY TO STOP ENDURANCE RUN

• The nozzle endurance run starts All nozzles are picked up successively and returned to the allocated

locations in each case (see above: "MEASURE Z-NOZZLE POSITIONS").

If an

error message

is displayed: Remedy see "MEASURE Z-NOZZLE POSITIONS", point 11.

3. Terminate

the procedure by pressing

any

key on the keyboard.

The nozzle that was picked up last is deposited and the main menu redisplayed.

The placement head is moved to the service position. The further procedure is as described above under

point 14.

7.13 EXECUTE NEXT 4 POINTS (Calibration of PCB Vision System)

Testing aids required

• VISION 2 calibration plate, item no. 00132070

• PCB

• Vacuum nozzle adapter, type 117, item no. 00300659

• Steel nozzle, type 104, item no. 00301435

• Teach panel, external, item no. 00132207

NOTE

For machines up to and including

batch identity no. 3

the conveyor width is now to be adjusted to the

width of the PCB (using the handwheel).

Select

"EXECUTE NEXT 4 POINTS"

The four measurement procedures are then carried out automatically and in the sequence required.

The PCB and the calibration plate have only to be inserted once at the beginning.

The communication test between the computer and ICOS is now performed automatically.

If the communication is interrupted the error "COMMUNICATION WITH ICOS IMPOSSIBLE" appears on the

screen:

Select "STORING" → terminate the program for the time being → switch off the machine → eliminate the error.

Possible causes:

— Interruption between computer and ICOS: Check the plug connections to the ICOS at the multiplexer

and the computer, replace the cable, if necessary.

— Incorrect camera no.: Check the camera numbers in the MA-Data (change on the line computer!).

3. The screen display for the conveyor width adjustment incl. the function keys appears:

ADJUST CONVEYOR WIDTH TO PCB WIDTH

➤ The explanation of the function keys is contained in section 5.1.19 "Conveyor Width Adjustment".

4. For checking purposes, place the PCB on the input conveyor, however not over the light barrier, as otherwise

width adjustment cannot be performed. The PCB should not jam nor have too much play.

5. Now, if you have not already done so, adjust the conveyor width to the width of the PCB used, using the

function keys offered (see section 5.1.19).

6. After adjusting the conveyor width, press the "END" function key. The following display appears on the scre-

en:

PLEASE PLACE A PC BOARD OVER THE SENSOR OF THE INPUT CONVEYOR

7. Place the PCB above the light barrier of the input conveyor. The PCB is conveyed to the center conveyor.

8. The graphical display of the position of the calibration plate and the following instructions are displayed on

the screen:

PLACE CALIBRATION PART ON MOTHERBOARD

ADAPTER ON NOZZLE ?

MACHINE MOVING TO SERVICE POSITION

PLEASE PRESS <START> KEY

➤ In place of the adapter also nozzle type 207 from the nozzle changer can be used.

To this end, install the nozzle insert (nozzle top part) in the sleeve of the placement head beforehand!

• Performance of the action:

Open the protective cover → take hold of the calibration plate only (!) by the outer edges → check whe-

ther the calibration plate is oxidized or contaminated: All metal surfaces must have the same coloring

→ replace the calibration plate with a new one, if necessary → place the calibration plate exactly in

the upper right corner of the PCB (see display on the screen) → check the points relative to the directi-

on of travel → slip the adapter onto the nozzle (no pointed nozzle!) → close protective cover → switch

on the control → now press the "START" button → the complete calibration is performed in the follo-

wing sequence:

• DETERMINE CALIBRATION FACTORS OF HEAD CAMERA

• DETERMINE ANGLE CORRECTION OF D-AXIS

• DETERMINE CAMERA NOZZLE OFFSET

• DETERMINE JAW OFFSET
