3.8 Calibration of the IC-Camera (SIPLACE 80F) Software Version 10.xx Edition 03/98

3 - 14

Overview of the Functions:

Pick up cal. tool to pick up the calibration piece with the IC-head

Return cal. tool to deposit the calibration piece in the calibration piece pocket

Measure focus to measure the focus position

Measure z-Delta to determine the z-delta (from the conveyor top edge to the focus position of the

IC-camera)

Focus pos. to display the measured focus position

●

From the "Meas.focus camera" menu select the

Pick up cal. tool

function and press the RETURN key.

The IC-head picks up the calibration piece with the nozzle and moves over the IC-camera.

●

Select the

Measure focus

function and press the RETURN key.

●

Using the cursor keys

↑↓

adjust the calibration piece until its sharply defined image is displayed on the

screen.

●

Actuate the cursor key

↑

repeatly until the calibration piece appears blurred. Note down the current z-axis

position (SIPLACE axis tester, axis 6, see "Service manual SIPLACE).

●

Actuate the cursor key

↓

repeatly until the calibration piece appears blurred. Note down the current z-axis

position (SIPLACE axis tester, axis 6, see "Service manual SIPLACE).

●

Determinate the mean value of these two z-axis positions.

●

Using the cursor keys

↑↓

position the axis to the mean value position. The calibration piece must appear

on the screen sharply defined.

●

Press the ESC key to return to the "IC camera" menu. Switch the monitor back to the normal program

mode.

●

Select the

Measure z-Delta

function and press the RETURN key.

The value thus determined is displayed on the screen.

●

Select the

Return cal. tool

function and press the RETURN key.

The IC-head deposits the calibration piece in the calibration piece pocket.

●

Press the ESC key to return to the "IC-camera" menu.

●

Select the

Calibrate IC-camera

function and press the RETURN key.

The calibration operation is performed on the IC-camera.

●

Select the

IC-ca.pos & offset

function and press the RETURN key.

The "IC-ca.pos & offset" menu is displayed on the screen (see section 3.8.2).

●

From the "IC-ca.pos & offset" menu select the

Measure

function and press the RETURN key.

The offset between IC-head and component camera and the position of the IC-camera are measured.

●

If you wish to view the values determined after the calibration procedure has been completed, select the

Calibration factors

menu function and press the RETURN key.

The values determined are displayed.

3.8.1 Changing the Illumination Values

NOTE

As a rule, changing the illumination values is not

required. Any change in the values performed in a non-expert

manner will result in incorrect calibration results.

●

From the "IC-camera "menu select the

Illumination values

option and press the RETURN key.

The "Illumination values" input menu is displayed on the screen.

Overview of the Functions:

Illumination steep steep angle of illumination

Illumination middle medium angle of illumination

Illumination flat flat angle of illumination

●

Change the values as required and confirm your entries by pressing the RETURN key.

●

Exit from the input menu by pressing the ESC key.

●

Repeat the calibration of the IC-camera as described in section 3.8.

3.8.2 Measuring the Offset From IC-Head to Component Camera and

IC-Camera Position

NOTE

Verify that the calibration data for the PCB camera, IC-camera and PCB/component camera offset have

already been determined.

●

Carry out the preparatory steps proceeding as described in section 3.1 and section 3.1.1.

●

From the "Vision system" menu select the

IC-camera

option and press the RETURN key. The "IC-camera"

menu is displayed on the screen.

●

From the "IC-camera" menu select the

IC-ca.pos & offset

function and press the

RETURN key. The "IC-ca.pos & offset" menu is displayed on the screen.

Overview of the Functions:

Camera position to display or enter the x and y-position of the IC-camera

IC-Camera Offset to display or enter the x and y-offset of IC-head to component camera

Measure to determine the offset between IC-head and component camera in x and

y-directions and to determine the IC-camera position

●

From the "IC-ca.pos & offset" menu select the

Measure

function and press the RETURN key.

The offset between IC-head and component camera and the position of the IC-camera is measured.

NOTE

Following the completion of the measuring operation the values determined can be displayed on the

screen using the

IC-Camera offset

function.

●

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