9. The procedure "DETERMINE CALIBRATION FACTORS OF HEAD CAMERA" follows automatically:

• The calibration plate is picked up, centered and put down again, the camera moves over the calibrati-

on plate, the calibration factors are determined, checked and displayed:

CAL. FACTORS CAMERA NO...

X1: -.0088 X2: 1.1783 X3: -.0149

Y2: -.0021 Y2: 1.4934 Y3: -.4704

VALUES X3 AND Y3 ARE NOT STORED BUT OCCUPIED WITH 0.

➤ If the error message "CHECK MEASUREMENT NOT SUCCESSFUL" is displayed, the values deter-

mined are ambiguous.

NOTE

The next menu option can only be performed if the check measurement was correct.

• Troubleshooting:

Press "RETURN" (values are not saved in this case) → press "END" (PCB together with calibration plate

is conveyed to the output conveyor) → remove PCB → visual inspect calibration plate for oxidation or con-

tamination → use new plate, if necessary → repeat the complete measurement (from point 1 onwards).

10. After the measurement has been successfully completed, "DETERMINE ANGLE CORRECTION OF

D-AXIS" follows automatically.

• The plate is picked up, centered, turned, put down and measured. The values determined incl. the de-

viation are displayed:

DETERMINE ANGLE OFFSET

ZERO POINT CORRECTION OLD : .......

ZERO POINT CORRECTION NEW : .......

ANGLE OFFSET MEASURED AND REFERENCE POINT FOUND

• If the discrepancy (old / new) is within the acceptable tolerance, the reference point run is carried out

using the new values. Otherwise, the display appears as under point 11.

11.The measurement is repeated with the new values. If the placement head is not within the tolerance when the

measurement is repeated, an error message is released and a display of the difference determined, as for example:

HEAD OUT OF TOLERANCE

MEASURED VALUE DIFFERENCE AT 0 AND 180 DEGREES: ....... DIGIT

THE VALUE OF THE ZERO POINT CORRECTION WILL NOT BE STORED

PLEASE CORRECT MANUALLY

• Locate the cause of the error (see listing below), eliminate the error and repeat the calibration, starting

with "DETERMINE CALIBRATION FACTORS".

Possible causes:

— Rotation error of D-axis → perform troubleshooting (see Service Manual HS-180, chapter 9,

29mm Head or Service Manual 30mm Head on HS-180)!

— Circular fiducials of the calibration plate are poor / incomplete → use a new calibration plate!

— Calibration factors are incorrect → Redetermine the calibration factors, then repeat the above

measurement!

12. If no error message is issued, the values determined are automatically transferred to the main memory.

13. "DETERMINE CAMERA NOZZLE OFFSET" follows automatically:

NOTE

If, when you are about to individually select this menu option, you are no longer sure whether you have in

the meantime exchanged or turned the calibration plate, you should in any case repeat the calibration,

starting with "DETERMINE CALIBRATION FACTORS".

Measuring procedure:

• The calibration plate is picked up, centered, turned and deposited. The distance between the nozzle

center and camera center is measured.

• The values determined including their algebraic signs are automatically displayed and saved:

CAMERA NOZZLE OFFSET

CAMERA OFFSET OLD X,Y ....... .......

CAMERA OFFSET NEW X,Y ....... .......

CAMERA NOZZLE OFFSET COMPLETED

14. "DETERMINE JAW OFFSET" follows automatically:

• The calibration plate is picked up, centered and put down, several times.

• The values determined are displayed and automatically transferred to the main memory.

JAW OFFSET

Z-JAW CORRECTION OLD : -.05 H-JAW CORRECTION OLD : -.07

Z-JAW CORRECTION NEW: -.05 H-JAW CORRECTION NEW: -.08

JAW OFFSET COMPLETED

15. Check the new jaws correction value displayed.

NOTE

The jaws correction value is displayed in mm (incl. sign).

The max. acceptable Z and/or H-jaws correction value is ± 0.20 mm.

➤ If the Z or H-jaws offset value is larger than ± 0.20 mm: adjust the symmetry of the jaws (see Service

Manual or adjusting instructions for jaws) → repeat the camera calibration, starting with "DETERMINE

CALIBRATION FACTORS".

16. After completion of all four measuring routines, all determined measurement results are displayed.

• Confirm the display with "RETURN".

17. The calibration plate is deposited, the PCB conveyed to the output conveyor and the main menu displayed.

• Remove the PCB, together with the calibration plate, from the output conveyor.

18. From the main menu, select "STORING". The values are transferred to the work diskette.

7.14 COMPONENT CAMERA MENU

For the procedure, note:

➤

First

determine the "COMPONENT CAMERA HEIGHT"

and then

"EXECUTE THE FOLLOWING POINTS".

➤ Correct calibration factors are a

prerequisite

for the further calibration (remember this when selecting the

menu options individually).

➤ After the measuring routine "DETERMINE CALIBRATION FACTORS" and acceptance of the new calibra-

tion factors (= after successful measurement!) the menu options "DETERMINE CAMERA CENTRE" and

"DETERMINE ROTATION ANGLE" on the component camera menu must

also

be carried out in any case!

➤ Moreover, when

individually selecting

the menu options, note:

The calibration plate must not be

exchanged or turned, not even

180 degrees,

between the individual

measuring procedures.

Testing aids required

• Steel nozzle in perfect condition, type 104, item no. 00301435

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

• VISION 2 calibration plate, item no. 00132070

• Teach panel (external), item no. 00132207

7.14.1 Procedure: "COMPONENT CAMERA HEIGHT"

NOTE

With machines up to and including

batch identity no. 3

, width adjustment is

now

to be performed using

the handwheel. However, this is not necessary if you only wish to carry out the measuring routine "COM-

PONENT CAMERA HEIGHT" as no PCB needs to be placed into the conveyor in this case.

From the main menu, select the

"COMPONENT CAMERA MENU"

The "COMPONENT CAMERA MENU" (see Fig. 1.4) is displayed on the screen.

• Now, if you have not already done so in the course of individual checks, install a steel nozzle in perfect

condition (normal size) → not a

pointed

nozzle!

First select

"CENTERING CAMERA HEIGHT"

. The following display appears on the screen:

’TEACH’ PLACEMENT HEAD OVER COMPONENT CAMERA

TEACHING IS ON, ’END’ TO FINISH

NOTE

In addition the current ACTUAL position of the placement head in X, Y and Z-directions is displayed.

Teach the nozzle in X/Y-direction approximately in the

center

above the glass disk of the component vision

module and then press "END" on the teach panel.

➤ The Z-axis is lowered by means of the sensor stop.
