EAOT Gripper Sysrem

It is the hand (with all necessary tools) of the robot used to unload the injection moulding machine.

Job of a EOAT

  • To take the moulded part out of the mould;
  • To grip it firmly;
  • To separate the moulded part from the sprue;
  • To grip the sprue after cutting;
  • To drop the sprue in the recycling machine;
  • To unload the moulded part onto a pallet/belt.
How EOAT Aassembled In brief
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.
Our Different EOAT/Gripper Systems
Sprue grippers
The sprue grippers are specifically designed to grip sprues.
90° movment cylinder
They are used for a steady clamping of the moulded part, together with the vacuum cups
One finger perpendicular acting gripper
A family of grippers where the jaw acts in a direction perpendicular to the piston
Bellow grippers
Several objects can’t be neither picked by vacuum cups, nor gripped effectively by a conventional pneumatic gripper.
Nippers
Five sizes are available for the pneumatic actuators, with the long body (for the sensor slots) or short.
Vacuum cup suspensions
The suspensions (or buffers) are used to compensate the vacuum cup position during the robot approaching to the mould.
Vaccum cups
The most common cups used in EOAT applications
