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

Abstract

Provided are a substrate holding device allowing a substrate held by the device to be accurately positioned by using a simple structure, capable of sucking the substrate with a sufficient sucking force, and not causing the substrate to come out of position, a substrate holding method, and a method of manufacturing laminated glass. A substrate holding device (10) for moving a substrate in the top-bottom direction while holding the substrate in a substantially horizontal position. The substrate holding device (10) is provided with a support body (2), at least one substrate sucking body (1) supported by the support body (2) and sucking the substrate, and a band-like elastic member (4) for interconnecting at multiple positions an outer peripheral section of the substrate sucking body (1) and that area of the support body (2) which is horizontally away from the outer peripheral section of the substrate sucking body (1). The band-like elastic member (4) has a displacing section located between one end thereof which connects to the substrate sucking body (1) and the other end thereof which connects to the support body (2), and the displacing section has a band-like shape wide in the horizontal direction and thin in the top-bottom direction. The displacing section displaces in the horizontal direction and also displaces so that the substrate sucking body (1) approaches and is separated from the support body (2) in the top-bottom 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
