Abstract
Disclosed are a cartridge nozzle assembly and an apparatus for injecting ink including the cartridge nozzle assembly. In the ink injecting apparatus for forming a pattern by adhering the ink injected from a nozzle onto a substrate, the ink injecting apparatus includes a cartridge nozzle assembly, in a cartridge type, including a chamber sealingly accommodating the ink, and the nozzle for discharging the ink accommodated in the chamber; and a cartridge nozzle fixing member for replaceably fixing the cartridge nozzle assembly.
Claims11
An apparatus for injecting ink to form a pattern by adhering the ink injected from a nozzle onto a substrate, the apparatus comprising:
- a cartridge nozzle assembly, in a cartridge type, including:
- a chamber accommodating the ink so as to seal the ink in the chamber;
- and
- the nozzle for discharging the ink accommodated in the chamber;
- and
- a cartridge nozzle fixing member for replaceably fixing the cartridge nozzle assembly;
- wherein the cartridge nozzle assembly comprises:
- a body including:
- the chamber forming a space for accommodating the ink in the chamber;
- and an ink supply path forming a path for supplying ink from an outside of the chamber into the chamber;
- and
- the nozzle including:
- a nozzle body which is in fluid communication with the chamber and which extends to have a constant tube diameter;
- and a nozzle tip formed to have a tube diameter tapering toward an end of the nozzle body and configured to discharge the ink;
- wherein the ink supply path is formed as an ink supply tube inserted into and fixed to a hole communicating between an outer surface of the body and the chamber and formed in a tubular shape to penetrate the chamber and to be spaced apart from a tubular inner surface of the nozzle body.
An apparatus for injecting ink to form a pattern by adhering the ink injected from a nozzle onto a substrate, the apparatus comprising:
- a cartridge nozzle assembly, in a cartridge type, including:
- a chamber accommodating the ink so as to seal the ink in the chamber;
- and
- the nozzle for discharging the ink accommodated in the chamber;
- and
- a cartridge nozzle fixing member for replaceably fixing the cartridge nozzle assembly;
- wherein a stepped portion is formed along a periphery of an outer side surface of the cartridge nozzle assembly, and the cartridge nozzle fixing member includes an insertion fixing part on which the stepped portion is mounted and into which the cartridge nozzle assembly is inserted to be fixed to the insertion fixing part;
- wherein the body further comprises a pneumatic supply path which forms a path through which pneumatic pressure is supplied from an outside of the chamber to an inside of the chamber;
- wherein at least one screw hole is formed at a side surface of the cartridge nozzle assembly, and the cartridge nozzle fixing member further includes a screw passing through a side surface of the insertion fixing part to be screw-engaged with the screw hole so as to fix the cartridge nozzle assembly.
An apparatus for injecting ink to form a pattern by adhering the ink injected from a nozzle onto a substrate, the apparatus comprising:
- a cartridge nozzle assembly, in a cartridge type, including:

- the nozzle for discharging the ink accommodated in the chamber;
- and
- a cartridge nozzle fixing member for replaceably fixing the cartridge nozzle assembly;
- wherein a stepped portion is formed along a periphery of an outer side surface of the cartridge nozzle assembly, and the cartridge nozzle fixing member includes an insertion fixing part on which the stepped portion is mounted and into which the cartridge nozzle assembly is inserted to be fixed to the insertion fixing part;
- wherein the cartridge nozzle assembly comprises:
- a body including:
- the chamber forming a space for accommodating the ink in the chamber;
- and an ink supply path forming a path for supplying ink from an outside of the chamber into the chamber;
- and
- the nozzle including:
- a nozzle body which is in fluid communication with the chamber and which extends to have a constant tube diameter;
- and a nozzle tip formed to have a tube diameter tapering toward an end of the nozzle body and configured to discharge the ink wherein the cartridge nozzle fixing member comprises an insertion fixing part allowing the cartridge nozzle assembly to be inserted into the insertion fixing part and fixed to the insertion fixing part, and a pneumatic supply port for supplying pneumatic pressure is formed at one side of the insertion fixing part, and wherein the pneumatic supply port and the pneumatic supply path are configured to be connected to each other when the cartridge nozzle assembly is inserted into the insertion fixing part and fixed to the insertion fixing part.
