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!

7. The following display appears on the screen:

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

TEACHING IS ON, ’END’ TO FINISH

• Performance of the action (analogous to point 4 above): Teach the camera so it is centered above the

left impression → press the "END" button on the teach panel → the new and old values for "CAMERA

NOZZLE OFFSET" and "ADHESIVE NEEDLE OFFSET" are displayed and transferred to the MA-Data of

the work diskette after "RETURN" has been pressed → the PCB is conveyed to the output conveyor.

• Remove the PCB from the output conveyor, the main menu is displayed. Select "STORING".

8. Now remove (= before glass mapping is carried out!) the MA-zero point insert (K-N-L)! The two adhesive

cartridges are not to be installed yet! = precautionary measure to protect the glass mapping plate!.

Thereafter continue the Routine Check with the menu option "glass mapping" (see section 8.5).

8.8 AXES MOVEMENT MENU

This menu only serves for testing purposes, error isolation and the adjustment of the X / Y-axes.

When carrying out the Routine Check, this menu is only required if a deviation > 2 counts was obtained du-

ring the initially performed axis adjustment (see "CHECK AXIS ADJUSTMENT").

➤ All details regarding the use of the AXES MOVEMENT MENU are contained in the description of this

menu option in section 5.1.20.

➤ Look up all safety instructions applicable during the performance of this menu in section 2.3!

8.9 I/O MENU

This menu is only selected for testing purposes and error isolation.

Skip this menu option when carrying out the Routine Check.

All details regarding the use of the I/O MENU are contained in the description of this menu option in section

5.1.21.

➤ Read the safety instructions contained in section 2.4 prior to the execution of this menu option.

➤ In particular, take heed of the WARNING in section 2.4 upon the concurrent setting of outputs!
