3.5.1.1 Description
The SIPLACE SpeedStar (C&P20) functions according to the Collect&Place principle, i.e. twenty
components are picked up by the placement head within a single cycle. 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&P20 head makes a significant increase in the placement head performance possible and
therefore in the performance of the placement machine. The compact design of the C&P20 head
also facilitates 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 its own DP drive for rotating the
nozzle. The nozzles are therefore no longer rotated into the correct position at a single head sta-
tion. They can be rotated into their placement position at any time and independently of one an-
other.
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.
