The Y axis mainly consists of the following modules:
– Y axis linear motor (primary part) (1)
– Permanent magnet (secondary part of the Y axis linear motor) (2)
– Linear distance measuring system (3)
– Guidance system (4)
– Trailing cable (5)
The Y axis is driven by a linear motor. The secondary part of the drive is made up of permanent
magnets and is mounted on the machine frame. The primary part is bolted to the gantry.

3.12 Vision Cameras
A component camera is integrated at each Collect&Place head (see fig. 3.7 - 2 page 144).
With the help of the component Vision module, the system determines
– the precise position of the components at the nozzle and
– the geometry of the component shape.
The PCB cameras are fixed to the bottom of the gantries. With the help of fiducials on the feeder
modules , you can determine the exact pick-up position of components, which is particularly im-
portant for small components.
The PCB Vision module uses fiducials on the boards to determine
– the position of the board,
– its rotation angle
– and its distortion.
