Description

Tray combination structure for panel storage container

Technical Field

The invention relates to a tray combination structure of a panel storage container. More particularly, the present invention relates to a tray coupling structure of a panel container for coupling a tray to an inside of the panel container.

Background

In processing a substrate such as a wafer for manufacturing a semiconductor or a panel for manufacturing various display devices, a panel for manufacturing a solar cell, or the like, it is known that protecting the substrate from a contaminant such as ambient moisture or oxygen and suspended matter in the air is a very important matter. Therefore, in the case of a substrate container used for storing and moving substrates, the substrate storage space therein is purged (pumping) with an inert gas such as N2 gas.

In addition, recently, the size of the substrate container is also increasing with the increase in the area of the substrate. In the field of manufacturing display devices, as various Flat panel display devices (Flat panel displays) such as Liquid Crystal Displays (LCDs), Plasma Display Panels (PDPs), Organic Light Emitting Displays (OLEDs), and the like have been increased in area, a technology for a substrate container for handling large-area substrates such as storage and movement has been developed, and the following detailed description is made with reference to patent document 1(KR10-1330110B1), for example.

Patent document 1 relates to a substrate storage container, and according to patent document 1, the storage container includes: a main body part having an opening formed in a front part thereof and accommodating the substrate; a door part for opening and closing the opening part of the main body part; and a locking device provided to the door portion, wherein the locking device includes: a main fixing unit for fixing and releasing the door part on the opening part side of the main body part; and an auxiliary fixing unit coupled to the opening portion side of the body portion, wherein the auxiliary fixing unit includes: a protrusion part linked with the main fixing unit to move in and out of the door part and combined with the body part; and a guide member for guiding the protrusion to enter and exit from the outside of the door.

According to the above-mentioned patent document 1, since the substrate storage container is a container capable of storing only wafers of 200mm or 300mm, there is a limitation in the conventional art for increasing the size of wafers, and in actuality, it is necessary to develop a technology capable of storing a container capable of storing wafers of more than 300 mm.
