A compact Yaskawa Motoman GP4 cell that singulates bolts and O-rings from two bowl feeders, fits each O-ring onto its bolt with a dual-action end effector, and conveys finished assemblies away.
The cell

Key components
- Vibratory bolt bowl feeder: high-speed bowl and linear track that singulate and orient raw bolts.
- Vibratory O-ring bowl feeder: dedicated bowl and escapement track engineered to stop O-rings nesting and present them one at a time.
- Auxiliary part holder & escapement station: staging platform with precision nests where parts are seated during intermediate assembly.
- 6-axis high-speed compact robot (GP4): agile arm for fast, precise micro-motion in miniature assembly.
- Dual-action insertion end effector: JS65B pneumatic actuator with two jaw sets: one clamps the bolt, the other expands and slides the O-ring over the shank into the groove.
- Outfeed takeaway conveyor: motorised belt carrying completed bolt-and-O-ring assemblies out of the work zone.
Close-up details

Vibratory bolt bowl feeder
The bowl and linear track singulate bolts and present them in a repeatable orientation at the escapement, so the robot always picks from the same point.
Vibratory O-ring bowl feeder
A dedicated bowl and escapement prevent O-rings tangling or nesting and feed them individually to the pick position.


Outfeed takeaway conveyor
Finished assemblies are placed on a motorised belt that carries them out of the robot envelope for packing or the next process.
