Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member for pressure-bonding and fixing a plate-like material, and more particularly to a pressure-bonding member suitable for fixing a glass substrate for liquid crystal for forming an electric functional element or the like on the front and back surfaces in a container. The present invention relates to a fixing member.

[0002]

2. Description of the Related Art When a glass substrate for a flat display such as a liquid crystal display is transferred, it is necessary to put the glass substrate in a container and fix it in order to prevent damage and dust generation due to vibration during transfer.

Since electric functional elements and the like are formed on the front and back surfaces of such a glass substrate for liquid crystals, it is necessary to maintain the surface quality and cleanliness. The fixing members are brought into contact with the front and back surfaces. This must be avoided as much as possible, and from this point of view, the storage container as shown in FIGS. 2 and 3 is used.

The storage container 10 shown in FIG. 2 has a deep-bottomed box shape having an opening for inserting the glass substrate 11, and a holding member for holding the glass substrates 11 in parallel on opposite inner wall surfaces at intervals in the thickness direction. Main body 13 having groove 12 and main body 1 thereof
3 and a shallow box-shaped lid portion 14 that fits into the insertion opening 3. Inside the lid portion 14, a pressure contact fixing member 15 is attached so as to abut the end face of the glass substrate 11. When this storage container 10 is used, when the glass substrate 11 is stored in the holding groove 12 formed in the main body portion 13 and then the lid portion 14 is put on the holding substrate 12, the glass substrate 11 is pressed and fixed by the pressure contact fixing member 15. Will be.

The storage container 16 shown in FIG. 3 has a shallow box shape having an opening for inserting the glass substrate 17 on one side, and holds the glass substrates 17 in parallel on opposite inner wall surfaces at intervals in the thickness direction. Upper and lower support members 19 and 20 having a plurality of holding grooves 18 and having the same shape, and a pressure contact fixing member 21 that is installed on the inner bottom surfaces of the upper and lower support members 19 and 20 and contacts the end surface of the glass substrate 17. , 22 and a packaging material 23 for encapsulating the glass substrate 17 held by the upper and lower support members 19 and 20 together with the upper and lower support members 19 and 20.

Incidentally, the pressure contact fixing members 15 and 2 as described above.
To attach 1, 22 to the lid portion 14 and the upper and lower support members 19, 20, a protrusion is formed at a predetermined position of the pressure contact fixing members 15, 21, 22 and the lid portion 14 and the support members 19, 20 are provided with predetermined protrusions. A method of forming a hole at a location and fitting them, or adhering with an adhesive or a double-sided adhesive tape is adopted.

[0007]

The holding groove of the storage container shown in FIGS. 2 and 3 is for holding the plate-like objects in parallel at a distance in the thickness direction, and has a function of fixing the glass substrate. Absent. That is, the glass substrate is fixed by bringing its end face into contact with the pressure contact fixing member.

By the way, a rubber-based cushioning material is widely used as a member for press-contacting and fixing such a storage container because it is inexpensive and can be easily washed repeatedly.

However, the rubber-based cushioning material has a high dusting property, and even if it comes into contact with only the end surface of the glass substrate, dust may be scattered to contaminate the front and back surfaces. Further, in the rubber-based material, its component is fixed to the substrate by coming into contact with the glass substrate, and when the electric functional element is formed on the substrate in a later step, the component wraps around to the front and back surfaces and is contaminated. There is a possibility.

The present invention has been made in view of the above circumstances, and particularly when a glass substrate for a flat panel display such as a liquid crystal display is transferred using an accommodating container having a pressure contact fixing member, the pressure contact fixing member. It is an object of the present invention to provide a pressure contact fixing member capable of preventing the glass substrate from being contaminated due to the above.

[0011]

A member for press-contacting and fixing a plate-like object of the present invention is fixed by pressing a plurality of plate-like objects held in parallel at intervals in the thickness direction from their end face directions. In the pressure contact fixing member, the base portion is made of a cushioning material, and the surface portion in contact with the plate-like material is made of a non-contaminating material.

Further, the member for pressing and fixing the plate-like object of the present invention is
The buffer material is a rubber-based material, and the non-staining material is a polytetrafluoroethylene-based material.

Further, the member for press-contacting and fixing the plate-like object of the present invention is characterized in that a plurality of grooves are formed on the surface portion, and the plate-like object is fixed at the bottom of each groove.

[0014]

In the member for pressing and fixing the plate-like object of the present invention, the base portion is made of the cushioning material, but the surface portion contacting the plate-like object is made of the non-contaminating material. 2 is used as a member for press-contacting and fixing a storage container as shown in FIGS.

Further, when a plurality of grooves are formed on the surface of the pressure contact fixing member and the plate-like member is fixed at the bottom of each groove, the following advantages can be obtained.

In recent years, for glass substrates for flat display devices such as liquid crystal displays, a storage container is installed so that the glass substrate is horizontal, and a glass substrate is automatically taken out from the storage container using a transfer machine. Is being introduced.

Usually, the holding groove formed in the storage container as shown in FIGS. 2 and 3 has a substantially V-shaped cross section as shown in FIG. When using, it is desired to have a U-shape as shown in FIG. The reason for this is that when taking out the glass substrates placed horizontally, if you lift them up a little from the lower surface of each glass substrate and take out the glass substrates horizontally from the holding groove, the holding groove and the glass substrate This is to prevent dust generation due to friction with.

However, in the case of the holding groove having a U-shaped cross section as shown in FIG. 5, the plate-like objects can move freely in the thickness direction by a large distance, and the plate-like objects are held in parallel at a predetermined interval. The original function of the groove is reduced. In such a case, when a plurality of holding grooves are formed on the surface that comes into contact with the plate-like object and a press-contact fixing member capable of fixing the plate-like object at the bottom of each holding groove is used, It is possible to give the storage container the function of fixing it at intervals.

[0019]
