3.5.1.1 Description
The SIPLACE SpeedStar(C&P20) 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 place-
ment 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 required
placement angle. Finally forced air sets down the component gently and accurately on the board.
The C&P head succeeds in considerably increasing the output of the placement head and thus of
the overall placement machine. The compact construction of the C&P20 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 component camera is still integrated into the C&P20 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.
