Abstract
An assembly for jetting droplets of a viscous medium. The assembly is releasably mountable in a machine using the assembly for providing a substrate with deposits. The assembly comprises an assembly holder having first holding means mating with an assembly support of a docking device of the machine, a nozzle, an eject mechanism connected to the nozzle, a viscous medium container connected to the eject mechanism, and signal interface means. Thus, the assembly is to be regarded as a separate, exchangeable unit.

An assembly for jetting droplets of a viscous medium, said assembly being releasably mountable in a machine using the assembly for providing a substrate with deposits, and comprising an assembly holder having first holding means for mating with an assembly support of a docking device of the machine, a nozzle, an eject mechanism connected to the nozzle, a viscous medium container connected to the eject mechanism, and signal interface means.
A docking device mountable in a machine for providing a substrate with deposits by jetting droplets of a viscous medium onto the substrate, said docking device comprising an assembly support for receiving an assembly to be used in the machine for said jetting, said assembly comprising an assembly holder having first holding means for mating with the assembly support, and signal interface means, said docking device having complementary signal interface means.
A machine for providing a substrate with deposits by jetting droplets of a viscous medium onto the substrate, comprising a docking device, said docking device comprising an assembly support for receiving an assembly to be used in the machine for said jetting, said assembly comprising an assembly holder having first holding means mating with the assembly support, a nozzle, an eject mechanism connected to the nozzle, a viscous medium container connected to the eject mechanism, and signal interface means, said docking device having complementary signal interface means.
A method of exchanging and calibrating an assembly for jetting droplets of a viscous medium, said assembly being releasably mounted in a machine using the assembly for providing a substrate with deposits, and comprising an assembly holder having first holding means mating with an assembly support of a docking device of the machine, comprising the steps of:
- exchanging the assembly for an exchange assembly;
- moving the exchange assembly to a calibration surface;
- depositing a plurality of deposits on the calibration surface;
- determining the position of said plurality of deposits by viewing it with a vision device comprised in the machine;
- and
- determining an offset of the position from an expected position.
An assembly for jetting droplets of a viscous medium, said assembly being releasably mountable in a machine using the assembly for providing a substrate with deposits, and comprising an assembly holder having first holder portions matable with an assembly support of a docking device of the machine, a nozzle, an eject mechanism connected to the nozzle, a viscous medium container connected to the eject mechanism, and a signal interface.
A docking device mountable in a machine for providing a substrate with deposits by jetting droplets of a viscous medium onto the substrate, said docking device comprising an assembly support for receiving an assembly to be used in the machine for said jetting, said assembly comprising an assembly holder having first holder portions matable with the assembly support, a signal interface, and a pneumatic interface, said docking device having a complementary signal interface, and a complementary pneumatic interface.
A machine for providing a substrate with deposits by jetting droplets of a viscous medium onto the substrate, comprising a docking device, said docking device comprising an assembly support for receiving an assembly to be used in the machine for said jetting, said assembly comprising an assembly holder having first holder portions mating with the assembly support, a nozzle, an eject mechanism connected to the nozzle, a viscous medium container connected to the eject mechanism, and a signal interface, said docking device having a complementary signal interface.
