• On the HS-180, the further sequence of operations is stated dependent on the available / activated option,

after selection of the main menu option "Mapping Menu" (see Fig. 1.4):

— Placement station with head camera glass or steel mapping ( → select mapping plate with function key)

— Placement station without head camera steel mapping.

• After selecting the appropriate menu option (and then the mapping plate, if required), the mapping subme-

nu (see Fig. 1.4) is displayed. Carry out the checks proceeding in the sequence of the menu options as of-

fered on the menu.

DANGER OF DAMAGE OCCURRING: Pay attention to the DANGER notes contained in the measuring

sequence description, chap. 7!

• The MA zero point correction values initially determined by mapping must be adopted for the measurement (the

values determined by means of the MA zero point gauge will, however, not be overwritten when so doing!).

➤ Requirements for valid (reproducible) measuring results:

• When carrying out the measurements the ambient temperature should not be below 18

or above 26

centigrade. Only within the above temperature range can be ensured that the temperature-related ex-

pansion of the mapping plate remains within the tolerance limit of ± 0.02 mm (expansion of the plate:

12 µm /

centigrade).

• The steel mapping plate incl. centering square must have already been adapted to the ambient tempe-

rature when the measurement is started. To this end, place the open mapping case (plate to be pro-

tected against damage) well in advance in the vicinity of the machine to be calibrated.

• The holes in the mapping plate and the centering pins must be clean and undamaged.

• The glass mapping plate must remain in the closed case up to the time of the measurement!

5.1.9 AXES INITIALIZING MENU

After selecting this main menu option a submenu appears (see Fig. 1.3) offering the possibility to either initialize indi-

vidual axes (e.g.. to check the pulse generator of an axis) or to initialize all axes. When initializing individual axes, the

displayed sequence H → Z → D → X → Y must be adhered to. When "ALL AXES" is selected, initialization is auto-

matically carried out in the above sequence. The "AXES INIT MENU" can also be called up from the "EDIT MENU".

5.1.10 NOZZLE MENU

➤ Prerequisite for the display of this measuring routine on the screen is that the HS-180 nozzle changer is

activated in the MA-data as follows:

• Under "Adapter / Nozzle changer " the value "2" must be entered

(0 = none / 1 = HS-180 adapter station / 2 = mechanical HS-180 nozzle changer, and

• under "NUMBER OF ADAPTERS" a number > 0 (default value = 10) must be entered

When a special holder is used, the number of the nozzles entered in the MA-data must be reduced to

"8" (7 normal holders plus one special holder = large holder).

Although these entries can be viewed in the editing menu under "Options" they cannot be edited.

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

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

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).
