4.2.3 White Balance Process for SIPLACE Digital Vision Camera

4.2.3.1 General Explanations

In order to compensate for the aging and contamination effects of illumination equipment in SIPLACE

Vision system camera, a white balance process has been planned and developed for this camera

generation.

The illumination factors stored in the camera EPROM have been measured and, where necessary,

adjusted for the individual illumination levels.

A similar balance process existed for the ICOS camera system and was known as the Field Camera

Calibration Service (FCCS) in that case. This abbreviated form was adopted for the SIPLACE Vision

camera system.

4.2.3.2 Cameras and Requirements

The camera white balance process is available from SR/MC 603.01 and is integrated into the SITEST

software. You need a SIEMENS FSE password to access it. The menus for illumination calibration or for

reading out data are available as single steps for the respective individual cameras and as a collective

menu, for all cameras configured at the machine, for complete machine calibration.

4-30: White balance calibration tools

NOTE:

NEVER touch the white balance

calibration tools!

Avoid contamination of any kind!

NOTE:

This needs to be removed on machines

with the third lane conveyor option.

4.2.3.3 Preparing for Calibration

To ensure that customer setups do not need to be changed, a black calibration tool carrier is moved into

PCB conveyor 1, is optically centered and clamped into place, the presence of the white balance

calibration tools is checked and illumination calibration (white balance process) is started.

NOTE:

The XML files for the white balance process are created before beginning measurement. To

view the data for the current calibration in the XML file, perform the balance process (with 603/

604.01) again; without saving the data when you exit SITEST. The files will then be in the folder

C:\SR-Daten\FCCS

X Go to

Calibrate illumination

in the

Calibrate

Entire Machine

menu.

X In the calibration menu for the entire machine,

you can specify the camera for which the

process is to be conducted (all/placement

area1/placement area2/head).

X The width adjustment will then automatically

set the width of conveyor lane 1 to the width of

the tray.

X The nozzles required for the illumination

calibration will be shown, as will the current

head setup. You may need to terminate the

menu, in order to configure the nozzles at the

head or to pick them up from the nozzle

changer.

X If you have a second placement head at the

gantry, the setup for this will be shown in a

separate window.

X The SITEST software will now request that

you place the calibration tool carrier into the

input conveyor. (Do not push in as far as the

input conveyor sensor!) Confirm each step

with the OK button. In this step, the tray is

moved into the processing area and is

clamped into place.
