If the component cannot be centered correctly, additional measuring methods may be omitted.
You should, however, carry out all the rough centering steps since these reduce the size of the
measuring window. 6
– In the ’Test component’ menu, the components are optically centered in the individual measur-
ing steps, via the ’Check component’ function, but the results are not output.
– In the ’Test component’ menu, the components are optically centered in the individual measur-
ing steps, via the ’Measure component’ function, but the results are not output.
– If the components are larger than 32 mm x 32 mm, a multiple measurement will be carried out
automatically in the vision system.

6.7.4 Test Package Form - Visual Representation / Programming Measurement
Types
In the ’Test component’ menu, a component is picked up and then moved to the camera and
mapped in its 0° position. The component is displayed with respect to its placement angle at the
revolver head. 6

Important note:
The manipulation of
components at the station must
remain the exception, rather
than the rule.
In general, only a few
components have to
be changed.

6.7.5 Parameters for the Measuring Methods
Possible sequences of measuring methods
It is also possible to program other sequences, such as corner followed by lead or lead only. Such
combinations are very unusual, however. If the component is defined in the package form editor,
then the measuring methods will be pre-assigned. However, in some cases it may be necessary
to modify the measuring methods at the station so that the component can also be optically cen-
tered. 6
The results from the last measurement are always saved. The previous measurement is used as
a rough centering step for the next measurement and thus helps to reduce the measuring win-
dow. 6
The more measuring methods are used, the longer the entire measuring procedure will be. A large
number of measuring methods for a component can delay the head cycle. This applies to the re-
volver head in SIPLACE automatic placement machines, in particular. 6
