5 Component Shapes

The component shapes and their features need to be described completely (and independently of the

camera type) for the image processing system. This description is to be made in the SIPLACE Pro

Component Shape Editor.

The following applies for the SIPLACE Vision image processing system:

 A correct description of the component shapes, with geometrically traceable values is essential! Use

the component shape data sheet as the basis for this description.

Note: In the case of ICOS systems, there are often no descriptions or the tolerance values may be

set very high.

 The component shape interpreted from the ICOS dataset is not necessarily the optimal shape for

SIPLACE Vision!

 Inaccurate descriptions of CS geometries may work for older ICOS systems, although they could

lead to errors or placement offsets in the SIPLACE Vision system, which tests more accurately.

 The simplest description of an object, which needs to be taught/programed with the camera before

application, is typically a Fiducial or an Inkspot.

The CS description, in contrast, must contain at least a group description.

NOTE: The image request at the camera is only triggered if the minimum requirements for component

shape data have been fulfilled (e.g. when all lead rows are described). Since SR/MC 603, the SIPLACE

Vision component shape type and the programming information for component shapes is

INADEQUATE.

 Component shape types also contain other shapes, all in all a total of 17. This arrangement allows

you to find the optimum algorithms and illumination parameters for each class, which significantly

reduces the teaching required.

5.1 Structure of Component Shape Data

The CS data in SIPLACE Pro consist of the following data and settings:

 Vision geometric data for the component shape; an assigned camera type; the nozzles to be used

and the inspection mode setting.

These settings can be edited in the CS Editor.

 Sensor-specific default settings.

The parameters for the individual cameras are not accessible and contain the default illumination

setting and the algorithms for the respective shape.

 Manipulation data.

These are created during CS teaching and are sensor-specific. They contain alterations to the

illumination value settings etc.

This dataset is currently not accessible for deleting, although it can be reset to default values.

 CO handling data (such as nozzles, vacuum checks, special procedures...).

These settings are made in SIPLACE Pro and can not be edited on the station interface or SIPLACE

Vision.

5.1.1 Component Centering with Combined Usage of SIPLACE Vision and ICOS

When using both Vision systems (ICOS and SIPLACE Vision) for component centering, you can select

either a common or a separate dataset for each CS number, in SIPLACE Pro. Separate datasets also

require separate maintenance. Only use this option, if you expect that geometric data which have been

taught for SIPLACE Vision will have a negative effect on the optical recognition in the ICOS system of

older machines.

Data management is as follows:

SIPLACE Vision processes the exact component shape dimension descriptions and can then alter these

through teaching. However, this may lead to recognition problems for some CS descriptions, when used

in ICOS Vision systems.

In these cases, it is advisable to keep the group data and lead data descriptions separately in SIPLACE

Pro.

This alternative option - separate data management - must be selected before you download to

SIPLACE Vision!

In rare exceptions, it may become necessary to create a completely new CS dataset for SIPLACE Vision,

if the SIPLACE Vision and ICOS descriptions are incompatible.

This could occur with various Moulded CSs (which have identical dimensions for ICOS), due to the

colored body and with various CSs, which have identical X/Y dimensions but different Z CO heights for

the CO sensor (in SIPLACE Vision).

The older ICOS image processing system

saves all teaching data in the SST file of the

relevant sensor type. The CS download data

consists of general data, group and lead

descriptions and the teaching data from the sensor

system type data area.

The SIPLACE Vision image processing system

saves the teaching data in a general data area; in

the group and lead descriptions and in the

manipulation data.

The CS download data consists of general data,

group and lead descriptions and the teaching data

from the manipulation data area.

Enabling the component shape default values,

resets the data to its default values (manipulation

data).
