Selecting the Nozzle Menu causes a submenu to appear (see Fig. 1.5) containing the following functions:

• EXECUTE NEXT 2 POINTS

This function successively calls up the next two functions. The nozzle changer is thus completely measured.

• MEASURE XY-COORDINATES OF NOZZLES

This function is used to measure only the X, Y- coordinates of all nozzle with the aid of the measuring ho-

les (as before).

• MEASURE Z -COORDINATES OF NOZZLES

The height of all nozzles is measured by picking up and returning the nozzles ten times (as before). Befo-

re the measurement, the steel nozzles must be replaced with the nozzle insert - as before - and the

nozzle changer must be loaded with the nozzles (the correct allocation to the holders to be observed - can

be looked up on the line computer). After the measurement, the steel nozzle must be re-installed.

NOTE

Prior to the continuous nozzle run be sure to select "STORING" so that the measured positions will be

transferred to the work diskette. The values are entered in the MA-data under

"Adapter Coordinates"

. Pri-

or to starting the placement cycle, the reference status of the nozzle changer must be established (see

10.1.4 "Final Work Prior to Starting the Station Software")!

• MEASURE ONE SINGLE NOZZLE

This function allows a single nozzle - independently of all other nozzles - to be measured.

• NOZZLE ENDUR. RUN

This measuring routine is used for testing purposes.

Prerequisite for the performance of the measuring routine: "DETERMINE ANGLE CORRECTION OF

D-AXIS" (head camera) must have been determined.

When this menu option is selected, all nozzles are successively picked up and deposited again. The

procedure is essentially the same as for "MEASURE Z-COORDINATES".

A corresponding error message may be issued:

— "NOZZLE FAULT DURING PICK-UP" or "NOZZLE FAULT DURING PLACEMENT"

Possible Causes of Error During Continuous Nozzle Run:

— In the case of "NOZZLE FAULT DURING PICK-UP" or "NOZZLE FAULT DURING PLACEMENT"

• Nozzle top portion (nozzle insert) is not inserted all the way.

• Location hole of the (new) nozzle is too small.

• Wrong pick-up data (nozzle positions) of nozzle.

• Position control of the X / Y-axis is outside the tolerance.

• Incorrect rotational position of D-axis prior to lowering the Z-axis (wrong D-zero point correction).

— The nozzle drops from the nozzle upper portion after pick-up (without message):

• The location hole of the nozzle is too large (outside the tolerance / worn).

• The Z-axis fails to move down far enough (Z-nozzle position is wrong).

5.1.11 EXECUTE NEXT 4 POINTS

This measuring routine allows you to carry out all menu options offered in the most favorable way:

• The PCB as well as the calibration plate have only to be inserted once at the beginning.

• The measurements are then carried out automatically and in the sequence required.

➤ Pay attention to the WORKAROUND pertaining to this menu option → section 12.4.

In order to check individual value, you can also select the "NEXT 4 POINTS" mentioned in the

following

indi-

vidually from the main menu:

• When selecting the menu options individually, observe the following:

Following the "DETERMINE CALIBRATION FACTORS" measuring routine, the

remaining

3 main menu options

must also be carried out if the new calibration factors are to be accepted(= after successful measurement!).

The calibration plate

must not be exchanged or turned

, not even 180 degrees, between the individual

measuring steps.

• Correctness of calibration factors is always a prerequisite for the checking of further values.

5.1.12 DETERMINE CALIBRATION FACTORS OF HEAD CAMERA

This measuring routine is used to determine the calibration factors of the head camera (for details see chapter 7).

• After changing the calibration factors,

all

of the following

points must always be performed!

5.1.13 DETERMINE ANGLE CORRECTION OF D-AXIS

This option is used to determine the D-zero point correction value (for details see description of operational

sequence, chapter 7).

5.1.14 DETERMINE CAMERA OFFSET

This measuring routine is used to determine the distance between the PCB camera and the nozzle center

(see chap. 7).

➤ Pay attention to the WORKAROUND pertaining to this menu option → section 12.4.

5.1.15 DETERMINE JAW OFFSET

The jaws offset represents the symmetrical offset of the Z or H-jaws (for details see chapter 7).

5.1.16 COMPONENT CAMERA MENU

The measuring routines of this menu are used to perform the complete calibration of the component vision system.

Since version 111.xxx the component camera may be assigned any track on the fixed side from 1 through 90. In

the case of BASIC MA-data, this track is to be entered when prompted to do so (default value is track 85).

• COMPONENT CAMERA HEIGHT

Selecting this menu allows you to determine the height of the centering camera (component camera).

This height serves as the reference value for lowering the Z-axis over the coplanarity laser module.

• EXECUTE THE FOLLOWING POINTS

Selecting this menu option allows you the perform the complete further calibration of the component vision

system after the centering camera height has been determined. The menu options displayed underneath

are now called up in a block (see below).

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

are then carried out automatically and in the sequence required.

Individual values can be checked by calling up the menu options individually:

• DETERMINE CALIBRATION FACTORS,

• DETERMINE CAMERA CENTER,

• DETERMINE ROTATION ANGLE,

Prerequisite for each succeeding calibration is always that the calibration factors have already been deter-

mined and are correct. The calibration plate must not be exchanged nor turned.

5.1.17 DETERMINE COPLANARITY COORDINATES

This measuring routines are used determine the exact laser coordinates (X, Y, Z-value of the laser focus).

These coordinates are prerequisite for the accurate coplanarity measurement during the placement cycle.

The laser coordinates determined are written to the MA_ZUSATZ file.

This file is saved during the AutoCal measuring sequence only if a coplanarity laser module has been set up

and activated in the MA-data.

The MA_Zusatz file must therefore be copied only in this case to the work diskette together with the MA_FILE.

The coplanarity laser module should be situated as close to the component camera as possible, however al-

ways on the fixed component table side. The X /Y-ACTUAL position is determined by teaching at the start of

the measuring routine.

Detailed information about the coplanarity laser module, such as e.g. DANGER warnings, requirements to be

fulfilled on the machine and required entries in the MA-data (activation of the "Coplanarity" option) are con-

tained in the "Retrofit Instructions of Coplanarity Laser Module on HS-180".

5.1.18 MEASURE ANY HOLE (REPEATEDLY)

This measuring routine is used for testing purposes and for an accuracy check of the machine in the case of

an error.

You can approach and measure any hole by means of "Teach" (reproducibility during measuring is ± 0.02

mm. After selecting the menu, the submenu providing the possibility for entering the criteria for the measure-

ment appears (see measuring sequence, chap. 7).
