Abstract

Provided is an apparatus of an inhalation type for stocking a wafer at a ceiling and an inhaling type wafer stocking system having the same including a stocking system having a shelf that is fixed to a ceiling and supports a container in which a wafer is present; and an inhalation assembly that is installed in the stocking system so as to correspond to the shelf and is configured so as to inhale gas that leaks from the container.

First claim

What is claimed is:

1. An apparatus of an inhalation type for stocking a wafer at a ceiling, comprising:
a stocking system including a shelf that is fixed to a ceiling and supports a container in which a wafer is present; and
an inhalation assembly that is installed in the stocking system so as to correspond to the shelf and is configured so as to inhale gas that leaks from the container;
wherein the inhalation assembly includes an inhalation module having an inhalation surface that intersects a main surface of the shelf; and
the inhalation module includes:
an inhalation late that forms an inhalation surface and is formed with an inhalation slit; and
an outer hood that is coupled to the inhalation plate and forms an internal space.

2. The apparatus of an inhalation type for stocking a wafer at a ceiling according to claim 1 ,
wherein the inhalation slit is formed at an edge of the inhalation plate.

3. The apparatus of an inhalation type for stocking a wafer at a ceiling according to claim 2 ,
wherein the inhalation slit has a plurality of sides corresponding to a closed roof.

4. The apparatus of an inhalation type for stocking a wafer at a ceiling according to claim 2 ,
wherein the inhalation module further includes:
an inner hood that is arranged in an internal space and is located within a region defined by the inhalation slit.

5. The apparatus of an inhalation type for stocking a wafer at a ceiling according to claim 4 ,
wherein the inner hood has the same shape as the outer hood and has a size smaller than the outer hood.

6. The apparatus of an inhalation type for stocking a wafer at a ceiling according to claim 4 ,
wherein the inhalation module further includes:
a sealing member that is formed by a closed roof surrounding the inner hood and is arranged between the inhalation plate and the outer hood.

7. The apparatus of an inhalation type for stocking a wafer at a ceiling according to claim 1 ,
wherein the inhalation assembly further includes:
an inhalation pipe that communicates with the internal space of the outer hood; and
an inhalation pump that is coupled to the inhalation pipe.

8. The apparatus of an inhalation type for stocking a wafer at a ceiling according to claim 4 ,
wherein the inhalation plate and the inner hood are respectively formed with removed portions corresponding to each other, and
wherein the stocking system includes a sensor bracket that is installed in the inhalation plate and is located in the removed portion.

9. The apparatus of an inhalation type for stocking a wafer at a ceiling according to claim 1 , further comprising:
a purge assembly that is installed in the stocking system so as to communicate with the container located on the shelf and that injects gas into the container to purge the wafer.

10. The apparatus of an inhalation type for stocking a wafer at a ceiling according to claim 9 ,
wherein the purge assembly includes:
a supply unit that is configured so as to supply the gas into the interior of the container; and
an exhaust unit that is configured so as to exhaust gas injected into the interior of the container.

11. The apparatus of an inhalation type for stocking a wafer at a ceiling according to claim 10 ,
wherein the shelf includes a supply nozzle and an exhaust nozzle that are formed so as to communicate with the interior of the container, and
wherein each of the supply unit and the exhaust unit includes:
a main pipe that is formed so that the gas flows therethrough; and
a subsidiary pipe that is branched from the main pipe and is coupled to the supply nozzle or the exhaust nozzle.

12. An inhaling type wafer stocking system comprising:
a vehicle rail that is fixed to a ceiling;
a vehicle that is movably coupled to the vehicle rail and carries a container, in which a wafer is present, along the vehicle rail;
a stocking system that is located beside the vehicle rail and is configured so as to have the container transferred thereto from the vehicle and stock the container;
a purge assembly that is installed in the stocking system and is configured so as to inject gas into the container and purge the wafer; and
an inhalation assembly is installed in the stocking system and is configured so as to inhale the gas that leaks from the container;
wherein the stocking system includes a shelf that supports the container and has a supply nozzle and an exhaust nozzle coupled to the purge assembly,
the purge assembly includes an inhalation module having an inhalation surface that intersects a main surface of the shelf, and
the inhalation module includes:
an inhalation plate that forms an inhalation surface and is formed with an inhalation slit; and
an outer hood that is coupled to the inhalation plate and forms an internal space.

13. The inhaling type wafer stocking system according to claim 12 ,
wherein the stocking system further includes:
a container detecting sensor that detects that the container is located, and
wherein the purge assembly and the inhalation assembly are operated if it is determined that the container is located on the shelf through the container detecting sensor.
