The vacuum cups and the grippers are the typical elements of the EOATs. They have to
support the moulded part during its handling out of the moulds.
If there are runners to be cut out of the moulds, the
air nippers and the sprue grippers are necessary too.
All these elements are mounted on a frame to be
set and hold in the needed position and direction. Sometimes they also need a
movement onto the frame.
The frame is mounted at the wrist of the robot by an interface easing the attachment and
detachment: the quick changer. When the injection moulding machine has a new job,
the EOAT (and the mould) have to be quickly replaced.
