7.11.3 Multizones model programming
Draw a synthetic image with BuildModel. Check the BuildModel pixel
size configuration and make it match your vision calibration.
In the library window click on this icon in the tool bar. Then appears a
box where you specify the name of the component.
To create a multizones model, after you draw a synthetic image with BuildModel, in the
Mod-
els
menu go to New multi area model… sub menu, then appears the box where you specify
the name of the component.
Later select the synthetic image created with build (.bmp file) in the
Open a BuildModel file

7.11.5 Vi-Pro, Edge, Histogram tools for multizones model
Program these tools exactly the same way you do for normal
model.
To place the treatments areas on
the right part of the component,
use the slider to see all the sub
zones created.
The multizones model can be only created with BuildModel
Type 2.

7.11.6 Custom tool for multizones model
The custom tool requires specific sub zones which are only used for this inspection. When
selecting the custom tool, the sub zones are automatically computed. In the custom tool for
multizones:
The body detection is done on 2 opposite
corners with 2 perpendicular helicopter
edges.
The component position and presence
is only computed with the body detec-
tion and not leads detection.
Only joints tools are realigned with the leads position. The bridges tools are realigned with
the body position.
7.11.7 Custom tool edition
7.11.7.1 Body detection
Press or button
to select the corners to use
for body detection.
In
Left Hight and Right
Low
(A) tabs the parame-
ters of the 4 rotating edges
are displayed.
Press
Propagate >>> (B)
button to propagate the pa-
rameters to the opposite
corner (Left/High sides on
this example).
Press
Propagate >>> (C)
button (in the tab) to propa-
gate the parameters to the
second edge of the same
corner (Right side on this
example).
Press
TEST (D) button (in the tab) to test the 2 rotating edges of the current corner.
Press
TEST (E) button to test the 4 rotating edges of the 2 corners.
Press
STEP BY STEP (F) button to test the 4 rotating edges of the 2 corners step
by step.
If no lead is detected on one
side, it does not return miss-
ing component.

7.11.8 Custom tool execution
7.11.8.1 Execution of one reference
Ctrl + E is the only way to debug your model on a real picture,
It takes pictures of each sub zones with the 5 light levels to ensure the changes,
It runs all the links and takes the number of pictures required.
7.11.8.2 Global execution
All the required pictures are taken for each link.
Some of the leads dis-
played on this picture
may be tested on the
following sub zone. That
is why you can not see
their test results.
Multizones are very time consuming.
