Description
3.2.9.1 Description
The C&P20A head works according to the Collect&Place principle (C&P), meaning that twenty
components are picked from the feeder modules (X feeders only) in one cycle. The component sensor
checks the pickup/place positions, to see whether a component has been taken by the nozzle or placed
on a board. On the way to the placement position, the components are rotated into the correct placement
position and optically centered. Before placement is performed, the angle and X/Y position correction,
determined by the Vision system, is applied. The X/Y position correction is calculated into the placement
position, while the angle correction is applied separately to each segment. This is possible as each
segment can be rotated independently of the star position. The components are then carefully and
accurately placed down on the board, with an air blast.
The component camera is still integrated into the C&P20A head. This saves additional travel to the
external centering cameras.

Each segment has its own DP drive for rotating the components into the correct position. The segments
are therefore no longer rotated into the correct angle in one single star position but can now be rotated
separately from one another.
Each segment has its own vacuum generator.
The Z drive for the segments is realized via a linear motor with linear position measuring system, which
makes it highly accurate. In the pickup/place position, the Z axis moves the segments up or down
(vertical direction).

3.2.9.2 Overview of Functions for Star Stations 1 - 20
Star station 1:
▪ Component pickup, placement or rejection
▪ Component sensor: Checks whether component is present after pickup and before placement.
▪ Component sensor: Checks whether no component is present after pickup and before placement.
▪ Vacuum/air blast measurement for pickup/placement circuit
Star station 12:
▪ Vacuum measurement for holding circuit
▪ By rotating the star axis, the vacuum value can be measured at each segment.
Star station 11:
▪ Optical measurement of components
Star station 2 - 10 and 12 - 20
▪ In these star stations, the component at the segment can be rotated into the correct position.
▪ In star stations 2 - 10, the component is rotated into the placement position.
▪ In star stations 12 - 20, angular correction is performed after optical measurement.
▪ Rotation to the correct angle position can be performed at any of the star stations, except 1 and 11.
