Substrate holding device, substrate holding method, and method of manufacturing laminated glass

Abstract

By employing a simple structure, there is provided a device for holding a substrate, a process for holding a substrate, and a process for manufacturing laminated glass, which are capable of determining the position of a substrate to be held with good precision, ensuring a force enough to attract a substrate and preventing a substrate from coming off. A device for holding a substrate 10, which is adapted to substantially horizontally hold a substrate and vertically move the substrate, is characterized to include a support 2; at least one substrate attraction member 1 supported by the support 2 and configured to attract the substrate; and a plurality of strip-shaped elastic members 4, which couple an outer peripheral portion of the at least one substrate attraction member 1 to regions of the support 2 apart from the outer peripheral portion of the at least one substrate attraction member 1 in a horizontal direction; wherein each of the strip-shaped elastic members 4 includes a deformable portion, which is formed as a strip-shaped member disposed between one end portion for coupling to the at least one substrate attraction member 1 and the other end portion for coupling to the support 2 and having a wide width in a horizontal direction and a thin thickness in a vertical direction, and which allows the at least one substrate attraction member 1 to relatively move closer to and apart from the support 2 in the vertical direction and is deformable in the horizontal direction.

Description

technical field [0001] The present invention relates to a substrate holding device, a substrate holding method, and a laminated glass manufacturing method used when manufacturing laminated glass and the like. Background technique [0002] Conventionally, it is known that a pair of glass substrates (substrates) are heated, Laminated glass formed by bonding together under pressure. Such laminated glass is used as the windshield glass of automobiles because broken glass fragments adhere to the film without scattering, and is used as window glass of buildings (safety glass, anti-riot glass) because of its good penetration resistance. use. [0003] In addition, in recent years, a method for producing laminated glass that does not require a high-temperature, high-pressure environment as described above has been proposed. As a method for producing such a laminated glass, for example, a method is known in which a curable resin composition is interposed between two upper and lower...

AI Technical Summary

Problems solved by technology

That is, if only a part of the pressure plate arranged at the end of the substrate is in local contact with the substrate, the part of the pressure plate that does not correspond to the substrate will be greatly inclined while moving downward, and the substrate will be pressed downward, causing May cause the retained substrate to fall off

[0008] Moreover, for such reasons, the device can only be used for substrates of specified size

In addition, although it is conceivable to configure the device in such a way that fluid is supplied separately to a plurality of pressurizing plates, since piping components, control components, etc. for this structure are required, new problems arise that the device becomes complicated and the cost of equipment increases.

In addition, if instead of the above-mentioned flexible material, for example, a torsion spring or a helical spring is used that becomes helical in the descending direction, not only the structure of the component becomes complicated, but also the length of the holding portion in the vertical direction increases, and the component The number also increases, and miniaturization cannot be achieved
