DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member for press-fixing a plate-shaped object, and more particularly to a press-contact member suitable for fixing a liquid crystal glass substrate 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.

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

[0003] Since electric functional elements and the like are formed on the front and back surfaces of such a glass substrate for liquid crystal, it is necessary to maintain surface quality and cleanliness, and a fixing member is brought into contact with the front and back surfaces. This must be avoided as much as possible, and from such a viewpoint, for example, a storage container as shown in FIGS. 2 and 3 is used.

The storage container 10 shown in FIG. 2 has a deep box shape having an opening for inserting the glass substrate 11, and holds the glass substrates 11 on the opposing inner wall surfaces in parallel in the thickness direction at intervals. A body 13 having a groove 12 and a body 1
3 and a shallow box-shaped lid portion 14 fitted into the insertion opening. Inside the lid portion 14, a press-contact fixing member 15 is attached so as to contact the end surface of the glass substrate 11. When the storage container 10 is used, after the glass substrate 11 is stored in the holding groove 12 formed in the main body portion 13 and then covered with the lid portion 14, the glass substrate 11 is pressed and fixed by the pressing and fixing member 15. Will be.

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

[0006] The pressing and fixing members 15, 2
In order to attach the cover members 1 and 22 to the cover portion 14 and the upper and lower support members 19 and 20, protrusions are formed at predetermined positions of the press-contact fixing members 15, 21 and 22, and predetermined portions of the cover portion 14 and the support members 19 and 20 are formed. A method is adopted in which a hole is formed at a location and fitted, or an adhesive or a double-sided adhesive tape is used for bonding.

[0007]

The holding grooves of the storage container shown in FIGS. 2 and 3 are for holding the plate-shaped objects in parallel at intervals in the thickness direction, and have a function of fixing the glass substrate. Absent. That is, the glass substrate is fixed by contacting the end surface thereof with the pressure fixing member.

By the way, rubber-based cushioning materials are widely used as the pressure-contact fixing members of such storage containers because they are inexpensive and can be easily washed repeatedly.

However, the rubber-based buffering 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 and contaminate the front and back surfaces. Furthermore, some of the rubber-based materials adhere to the glass substrate by contact with the glass substrate, and when forming an electric functional element on the substrate in a later process, the component goes to the front and back surfaces to contaminate it. 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 display such as a liquid crystal display is transferred using a storage container having a press-contact fixing member, the press-contact fixing member is used. It is an object of the present invention to provide a pressure contact fixing member capable of preventing contamination of a glass substrate caused by the above.

[0011] The plate-like member for press-contact fixing of the present invention includes a plurality of plate-like members held in parallel at intervals in a thickness direction.
A press-contact fixing member that can be fixed by press-contacting from an end face direction thereof, wherein a base portion is formed of a buffer material, and a surface portion in contact with the plate-like material is formed of a non-staining material. And multiple grooves are formed on the surface,
The plate-like object is fixed at the bottom of each groove .

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

[0013]

[0014]

In the member for fixing a plate-shaped object to pressure contact according to the present invention, the base portion is formed of a buffer material, but the surface portion in contact with the plate-shaped member is formed of a non-staining material. Is used as a member for pressing and fixing the storage container as shown in FIGS. 2 and 3, it is possible to prevent contamination of the plate-like material due to the member for pressing and fixing.

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

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

Normally, the cross-sectional shape of the holding groove formed in the storage container as shown in FIGS. 2 and 3 has a substantially V-shaped shape as shown in FIG. In the case where is used, it is desired to have a U-shaped shape as shown in FIG. The reason for this is that when taking out the glass substrates placed horizontally, lift them slightly above the lower surface of each glass substrate, and take them out horizontally in a state where the glass substrates are lifted from the holding grooves. This is to prevent dust from being generated due to friction with the brush.

However, in the case of a holding groove having a U-shaped cross section as shown in FIG. 5, the distance that the plate-like object can freely move in the thickness direction is large, and the plate-like object is held in parallel at a predetermined interval. The original function of the groove will be reduced. In such a case, when a plurality of holding grooves are formed on a 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, the plate-like object is formed. The storage container can have a function of fixing at intervals.

[0019]
