3.11 Calibration of the Nozzle Changer Software Version 10.xx Edition 03/98

3 - 22

NOTE

The "Cal.noz.chang.compl." function is used if all seven magazines of the nozzle changer are completely

occupied. Moreover, all 12 nozzles must be present at the revolver head.

If the nozzle changer is not completely occupied, the x and y-values must be determined separately for each

magazine using the "Calibrate magazine" function.

●

Select the

Cal.noz.chang.compl.

function and press the RETURN key.

The PCB camera approaches the measuring holes of all magazines in the nozzle changer and then calcu-

lates from the positions determined the x and y-values for each magazine compartment. If the nozzle

changer is not completely occupied, select the

Magazine [1 .. 7]

menu option and press the RETURN key.

The input field for the magazine number opens.

●

Enter the desired magazine number and confirm your entry by pressing the RETURN key.

●

Press the ESC key.

●

Select the

Calibrate magazine

function and press the RETURN key.

The PCB camera approaches the measuring hole of the selected magazine and subsequently that of the

next magazine and then calculates from the positions determined the x and y-values of the magazine com-

partments.

●

Select the

Disp. nozzle positions

function and press the RETURN key.

A comparison of the setpoint values versus the actually determined values in x and y-direction is displayed

on the screen for each selected compartment (garage) of the selected magazine.

●

Select the

Garage [1 .. 12]

menu option and press the RETURN key.

The input field for the garage number opens.

●

Enter the number of an unoccupied garage and confirm your entry by pressing the RETURN key.

●

Press the ESC key.

●

Select the

Return nozzle

function and press the RETURN key. The nozzle is returned to the garage.

NOTE

When the height of all nozzle changer garages is determined, the z-position that was read most recently is

saved upon "Return nozzle" or "Pick up nozzle".

●

Select the

Magazine [1 .. 7]

menu option and press the RETURN key.

The input field for the magazine number opens.

●

Enter the first available magazine (e.g.: 1) and confirm your entry by pressing the RETURN key.

●

Press the ESC key.

●

Select the

Garage [1 .. 12]

menu option and press the RETURN key.

The input field for the garage number opens.

●

Enter the number of an unoccupied garage and confirm your entry by pressing the RETURN key.

●

Press the ESC key.

●

Select the

Return nozzle

function and press the RETURN key. The nozzle is returned to the garage.

●

Thereafter, select the

Pick up nozzle

function and press the RETURN key.

The nozzle is picked up. (The height determined is displayed. Note down the value of the z-position).

●

Select the

Magazine [1 .. 7]

menu option and press the RETURN key.

The input field for the magazine number opens.

●

Enter the number of the last available magazine (e.g.: 7) and press the RETURN key.

●

Press the ESC key.

●

Select the

Garage [1 .. 12]

menu option and press the RETURN key.

The input field for the garage number opens.

●

Enter the number of an unoccupied garage and confirm your entry by pressing the RETURN key.

●

Press the ESC key.

●

Select the

Return nozzle

function and press the RETURN key. The nozzle is returned to the garage.

●

Thereafter, select the

Pick up nozzle

function and press the RETURN key.

The nozzle is picked up. (The height determined is displayed. Note down the value of the z-position).

●

Repeat the measuring procedure on the magazine with the smaller z-position. The height thus determined

is then saved upon "Saving the machine data".

●

For the z-position to be entered for all magazines, the

Cal.noz.chang.compl.

calibration procedure must

be repeated.

NOTE

If a magazine is calibrated after a nozzle has been picked up or returned, the z-position value of that nozzle

will always be saved as the current value. It is therefore important that the z-position value is correct.

NOTE

The "Pick up nozzle" function will measure an incorrect z-position if a nozzle is still present at the head.

It is therefore important that the correct operational sequence be adhered to when determining the height of

the z-position. (Nozzle is to be returned and then to be picked up).

NOTE

The X,Y-position of the reject box is only determined when the 7th magazine is measured.

●

To determine the height of the rejecting position select the

Reject nozzle

function and press the

RETURN key.

The nozzle is discarded into the reject box. (The height determined is displayed).

●

Press the ESC key three times to return to the SITEST main menu.

●

Save the current calibration data proceeding as described in section 3.12.

3.11.2 Calibration of the IC-Nozzle Changer

●

To calibrate the IC-nozzle changer, select the

Noz.changer IC-head

option from the "Nozzle changer"

menu and press the RETURN key.

The "Noz.changer IC-head" menu is displayed on the screen.

Overview of the Functions:

Cal.noz.chang.compl. to determine the x and y-values for each nozzle changer compartment

Calibr. fiducial 1 to calibrate reference marking "1" (marking "1" is close to the PCB conveyor)

Calibr. fiducial 2 to calibrate reference marking "2" (marking "2" is close to the component table)

Disp. nozzle positions to display the values determined for each nozzle changer compartment

Pick up nozzle to pick up the nozzle from the selected nozzle changer compartment

Return nozzle to return the nozzle to the selected nozzle changer compartment

(determination of the z-height)

Garage [1..20] to select the nozzle changer compartment

Positions to display the pick-up positions.

(The data can be edited, if required.)

NOTE

For the calibration of the IC-nozzle changer it is necessary that a magazine is present in the 1st and 4th

magazine location of the nozzle changer.

For the determination of the nozzle positions, reference marking "1" and

reference marking "2" must be

calibrated.

●

Select the

Cal.noz.chang.compl.

function and press the RETURN key.

The PCB camera approaches the measuring holes (reference markings "1" and "2") in the nozzle changer

and calculates from the positions determined the x and y-values for each nozzle changer compartment.

●

Select the

Disp. nozzle positions

function and press the RETURN key.

A comparison of the setpoint values versus the actually determined values in x and y-direction is displayed

on the screen for each selected nozzle changer compartment.

●

If you wish, for example, to calibrate reference marking "1", select the

Calibr. fiducial 1

function and press

the RETURN key.

The PCB camera approaches reference marking "1" (measuring hole 1) in the nozzle changer and calcu-

lates, from the values determined, the nozzle pick-up position.
