Abstract

A wrapping member for wrapping a glass substrate to be used in production of a FPD such as a liquid crystal display and a plasma display and a method of transferring a glass substrate for FPD, in which the wrapping member for wrapping either one or both of the surfaces of the glass substrate for FPD before transfer is made of a water-soluble film material dissolved in water, so that preprocessing of each of the glass substrates in the production line of the FPD may be simplified and so that the outer shape of a package formed by packing the glass substrates in a transfer box and a lid for closing the transfer box is reduced to an extent enabling a plurality of the glass substrates to be transferred at a high efficiency.

Benefits of technology

[0008] Therefore, to overcome the above-described problems encountered by the conventional art, an object of the present invention is to provide a wrapping member for a glass substrate for FPD, which enables it to simplify the processing of the glass substrates and the wrapping member on the production line of the FPD, and to reduce the outer size of the wrapped glass substrates thereby allowing the glass substrates to be transferred at a high efficiency.

[0011] Due to the above-described constitution of the present invention, the wrapping member used for wrapping the glass substrate for FPD can be dissolved in the water without becoming industrial wastes. Therefore, wrapping of the glass substrate with the water-soluble film can simplify the processing of respective glass substrates and the wrapping member on the production line of the FPD and additionally, reduce the outer size of the glass substrate in its wrapped condition for transfer thereby allowing the wrapped glass substrate to be transferred at a high transferring efficiency.

[0017] When the above-mentioned method is carried out, either one or both of the surfaces of each glass substrate for FPD is laminated with the water-soluble film, and a plurality of the glass substrates, each being laminated with the water-soluble film, is stored in the transfer box in a condition such that they are superposed one another. Then, the transfer box is closed by covering the open end of the transfer box with the lid so as to form a packed transfer box with the glass substrates stored therein, and the packed transfer box is subjected to the transferring process. Owing to this method, the outer size of the packed transfer box can be small enough for being transferred at a high transferring efficiency.

[0018] Further, the above-mentioned transfer box and the lid are preferably made of material having hydroscopic property. Owing to this hydroscopic property of the material of the transfer box and the lid, the transfer box together with the lid may absorb the humidity in the atmosphere, so that solving of the water-soluble film may be prevented. Accordingly, during transferring of the glass substrates in the transfer box, the glass substrates can be always kept in a condition where the glass substrates within the transfer box are prevented from coming in contact with one another and therefore the surfaces of the glass substrates may be protected against damage.

[0019] Further, the transfer box and / or the lid may be provided with drying agent or desiccant in the inside thereof. Thus, any humidity contained within the transfer box and the lid may be absorbed by the drying agent or the desiccant, so that solving of the water-soluble film during the transferring of the glass substrates in the transfer box may be prevented. Therefore, during transferring of the glass substrates in the transfer box, the glass substrates can be always kept in a condition where the glass substrates within the transfer box are prevented from coming in contact with one another and therefore the surfaces of the glass substrates may be protected against damage.

Problems solved by technology

Nevertheless, the larger is the size of the glass substrate, the greater must be the bending of the glass substrate.

Namely, the volume of the transfer box 1 must be increased depending on an increase in the size of the glass substrate 5 and accordingly, the outer size of the transfer box 1 must be larger resulting in making it difficult to obtain an increased efficiency in the transfer of the transfer box 1 with the glass substrates therein.

Therefore, in such case, it has been needed to completely remove such residual adhesive 11 from the surface of the glass substrate 5, which renders a pretreatment process of the glass substrate 5 for FPD rather cumbersome.
