Apparatus and method for transporting a vessel to and from a PECVD processing station
View Patent ↗Methods for processing a vessel, for example to provide a gas barrier or lubricity, are disclosed. First and second PECVD or other vessel processing stations or devices and a vessel holder comprising a vessel port are provided. An opening of the vessel can be seated on the vessel port. The interior surface of the seated vessel can be processed via the vessel port by the first and second processing stations or devices. Vessel barrier, lubricity and hydrophobic coatings and coated vessels, for example syringes and medical sample collection tubes are disclosed. A vessel processing system and vessel inspection apparatus and methods are also disclosed.
1. Apparatus for PECVD treatment of a first vessel having an open end, a closed end, and an interior space, comprising:
a vessel holder configured for seating to the open end of a vessel;
a first gripper configured for selectively holding and releasing the closed end of a vessel and, while gripping the closed end of the vessel, transporting the vessel to the vicinity of the vessel holder;
a seat on the vessel holder, the seat configured for establishing sealed communication between the vessel holder and the interior space of the first vessel;
a reactant supply operatively connected for introducing at least one gaseous reactant within the first vessel through the vessel holder;
a plasma generator configured for forming plasma within the first vessel under conditions effective to form a reaction product of the reactant on the interior surface of the first vessel;
a vessel release for unseating the first vessel from the vessel holder; and
a gripper which is the first gripper or another gripper, configured for axially transporting the first vessel away from the vessel holder, and then releasing the first vessel.
2. The invention of claim 1 , further comprising
a series conveyor configured to transport grippers; and
a second gripper configured for selectively holding and releasing the closed end of a vessel and, while gripping the closed end of the vessel, transporting the vessel to the vicinity of the vessel holder;
the first and second grippers operatively connected to the series conveyor and configured for successively transporting a series of at least two vessels to the vicinity of the vessel holder, seating the open ends of the vessels on the vessel holder, establishing sealed communication between the vessel holder and the interior of the second vessel, axially transporting the vessels away from the vessel holder, and releasing the vessels from the grippers.
