Semi-automated Fuel Line Forming and Leak Test Machine

This German client manufactures fuel line assemblies and required a machine that would form a plastic fuel line by heating and cooling various bends that are shaped in the nest on a high-speed indexing dial table.

Each nest on the table houses various electric heaters and temperature sensors that require connection and disconnection during the rotation of the table. This is performed using a retractable bed-of nails-type electrical interface that is maneuvered by pneumatic cylinder.

A pick & place unit moves the final assembly to a final station where it is pressure-leak tested and paint-marked to indicate a good part.

The cycle time is approximately fifteen seconds.
