[0045] First, the overall schematic structure of the manufacturing apparatus of the glass plate which concerns on 1st Embodiment of this invention is demonstrated. figure 1 It is a vertical front view showing its overall schematic structure. It should be noted that in the following description, the figure 1 The direction perpendicular to the paper surface is called the width direction. As shown in this figure, the manufacturing apparatus 1 of a glass plate is comprised so that the glass plate 3 in the chamber 2 may be conveyed horizontally while the glass plate 3 carried in from the inlet 2a into the chamber 2 is conveyed. In the processing area 4 provided on the path, etching processing is performed using hydrogen fluoride as the processing gas 5 . Then, the etched glass plate 3 is carried out of the chamber 2 through the export port 2b.

[0046] The outer shape of the chamber 2 is formed in the shape of a rectangular parallelepiped elongated in the width direction, and th...

[0067] Next, the manufacturing apparatus (the manufacturing method) of the glass plate which concerns on 2nd Embodiment of this invention is demonstrated. It should be noted that, in the description of the second embodiment, the constituent elements already described in the above-mentioned first embodiment are denoted by the same reference numerals with reference to the accompanying drawings and redundant descriptions are omitted. Differences from the first embodiment will be described.

[0068] like Image 6 As shown, the difference between the glass plate manufacturing apparatus 1 of the second embodiment and the glass plate manufacturing apparatus 1 of the above-mentioned first embodiment is that only the upper gas supply port 22 in the lower structure 11 The specific conveyance roller 9 is assembled on the rear side in the conveyance direction, and the conveyance roller 8 is arranged adjacent to the front side of the front end portion in the conveyance direction of the lo...

Abstract

A lower surface 10a of an upper structure 10 is arranged in opposition to an upper surface 11a of a lower structure 11 having a gas supply opening 22 and a gas discharge opening 26, and a lower surface 3a of a glass plate 3 transported in the horizontal direction is subjected to an etching treatment in a treatment space 13 formed between said opposing surfaces 10a, 11a with a treatment gas 5 thatis blown out from the gas supply opening 22 and sucked into the gas discharge opening 26. The gas supply opening 22 and the gas discharge opening 26 are located so as to be separated in the glass plate transporting direction A. A specific transporting means 9 assembled to the lower structure 11 is used to support the glass plate 3 from below and transport the glass plate 3. The specific transporting means 9 is arranged outside a region between the gas supply opening 22 and the gas discharge opening 26.

Description

technical field [0001] The present invention relates to a method of manufacturing a glass plate and a manufacturing apparatus thereof, which include a step of etching a glass plate using a process gas such as hydrogen fluoride. Background technique [0002] As we all know, glass plates of various thicknesses and sizes are incorporated in mobile devices such as flat panel displays (FPDs), smartphones, tablet PCs, and other electronic devices. Organic EL displays, field emission displays, and the like are representative. [0003] In the original glass plate manufacturing process for producing such a glass plate as a final product, problems due to electrostatic charging may arise. For example, when a glass plate is placed on a workbench and a predetermined process is performed, the glass plate may stick to the work surface due to electrostatic charging. For this reason, when the glass plate which completed the predetermined process is peeled off from a workbench, the said gla...
