3.5.1.1 Description
The 20-segment Collect&Place head works on the Collect&Place principle. This means that,
within each cycle, twenty components are picked up by the placement head. At the pick-up and
placement position the component sensor checks that the component is present at the nozzle. On
their way to the placement position the components are optically centered and rotated into the re-
quired placement angle. Finally forced air sets down the component gently and accurately on the
board.
The C&P20A head succeeds in considerably increasing the output of the placement head and
thus of the overall placement machine. The compact construction of the C&P20A head allows very
short cycle times. In this case, the star axis is at an angle to the PCB level. This geometry allows
the segments to be arranged in a very small space.
The CO camera is still integrated into the C&P20A head. This saves additional traveling distances
to external centering cameras. Each segment also has a separate DP drive for rotating the nozzle.
The nozzles are therefore no longer rotated into the correct position at a single head station. They
can be rotated into their placement position at any time and independently of one another.
Each segment has a separate vacuum generator. This greatly reduces the time taken to switch
between vacuum and air kiss. It also allows a vacuum check to be carried out in the holding circuit
for each individual nozzle.
The Z drive for the segments is implemented with a linear motor with linear path measuring sys-
tem, and is thus extremely precise. In the pick-up/placement position, the Z drive moves the seg-
ments up or down in the vertical direction.
