1.13.5 Description of the 6-segment collect&place head
The functionality of the 6-segment revolver head is similar to that of the 12-segment revolver head.
With its standard vision module, the 6-segment revolver head can quickly and accurately place
ICs with an edge length of up to 32mm x 32mm. It really comes into its own when there is a very
high proportion of ICs in the placement process. The cycle time of the 6-segment revolver head
depends on the dimensions and number of component leads or bumps. 1

1.14 Overview of the modules - vision modules
Each placement system has 1
– two component vision cameras on the placement heads and
– two PCB vision cameras on the underside of the X-axis gantries.
1
The vision analysis unit is located in the control unit for the placement system and the component
vision module is used to determine: 1
– the precise position of the components at the nozzle and
– the geometry of the package form.
1
The PCB vision module uses fiducials on the PCBs to determine: 1
– the position of the PCB,
– its rotation angle
– and the PCB delay.
1
The PCB vision module also uses fiducials on the feeder modules to determine the exact pick-up
position of components, which is particularly important for small components. 1
