► Remove the camera screen(1). This is
fastened with two black screws(2).
NOTICE!
Only use these black screws to fix the
camera lens hood. This prevents re-
flection when measuring components
with the stationary camera.

Fig.415: Fastening screws
Each module is fixed with four screws to the
head plate and is positioned with two pins.
► Remove the four M4x14 fastening
screws (1) with a long Allen key.
CAUTION!
Hold tight!
Hold the module tight before removing
the last of the four screws. The module
could otherwise fall down.
.
► Pull the module out of the locating pins.
► Placing the head into the head transport box
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following
instructions:
– Fit the fastening screws on the other side of the module, if needed (see above).
– Make a note of the force values for the new module. These force values can be found on a
label at the side of the module.
– Make sure that the assembly position is correct.
– Perform a head calibration.

8.9 Calibration
Overview
With the calibration of the component camera the following values are determined:
the relationship of "camera pixel size to resolution of machine measuring system (X,Y)", the "cam-
era center point in X and Y direction" and the "torsion angle of the CCD sensor in the camera". This
is following by determining the head offset and the segment offsets for the top and bottom.
●
Head offset: the head offset is the distance between the PCB camera and the nozzle (seg-
ment1). The target is a fixed value (X=0 and Y=‑105mm) to which an offset value (from the
head calibration) is added.
●
Segment offset top: the top segment offset involves turning the calibration tool in the compo-
nent camera in 0°, 90°, 180° and 270°. The value determined is that of the rotating center of
the nozzle tip in relation to the component camera center in the X and Y direction.
●
Segment offset bottom: the bottom segment offset involves recording and measuring the
calibration tool in the 0°, 90°, 180° and 270° positions. The value determined is that of the ro-
tating center point of the nozzle tip when the Z axis is extended in relation to the PCB camera.
Segment 1 is the reference (X=0, °Y=0) for the other segments.
8.9.1 Calibration procedure
