Problems solved by technology

However, when the stretched members to be bonded are bonded, the surface of the coated and stretched adhesive and the surface of the other side of the disk are in contact with each other at the initial stage of bonding, so it is easy to cause a closed area. Air bubbles in the adhesive layer, and there is a shortcoming that the air bubbles generated temporarily are not easy to escape

Embodiment Construction

[0051] Next, the first embodiment of the present invention will be described by taking the manufacture of DVD as an example.

[0052] FIG. 1 shows a schematic configuration of a DVD manufacturing apparatus. In the figure, the symbol R1 is a disk substrate extraction part, the symbol R2 is a disk production part, the symbol R3 is a disk inspection part, and the symbol R4 is a disk extraction part, and they are all accommodated in a box not shown in the figure.

[0053] The disk substrate take-out section R1 is composed of a stacking area A1 and a take-out area A2. In this stacking area A1, two disk substrates 1a and 1b for bonding a single disk (DVD) are stacked in a stacked state, respectively. The holder 2 takes out the disk substrates 1 a and 1 b held in each disk holder 2 one by one in the take-out area A2 .

[0054] The disk production unit R2 is composed of a coating device (coating means) 3, an ultraviolet irradiation device (ultraviolet irradiation means) 4, a bonding ...

Abstract

A method for manufacturing discs by bonding two disc substrates (1a, 1b) using a cationic polymerization type ultraviolet curable composition (S) as an adhesive to produce a disc (1). The method includes the steps of: applying the cationic polymerization type ultraviolet curable composition onto a part of an adhering surface of one of the two disc substrates; radiating ultraviolet light onto the cationic polymerization type ultraviolet curable composition; bonding the disc substrate to the other disc substrate via the cationic polymerization type ultraviolet curable composition which has been irradiated by the ultraviolet light; and spreading the cationic polymerization type ultraviolet curable composition which is present between the two disc substrates.

Description

technical field [0001] The present invention relates to a bonding method for bonding two members to be bonded by using a cationic polymerizable ultraviolet curable composition as an adhesive, and also relates to a bonding method using a cationic polymerizable ultraviolet curable composition as an adhesive Disclosed are a disk manufacturing method and a disk manufacturing apparatus in which two disk substrates form one disk. Background technique [0002] Conventionally, methods for bonding various members such as plastic parts mainly include methods using adhesives such as hot-melt adhesives, solvent-based adhesives, and ultraviolet curable compositions, and methods using heat welding. [0003] In addition, when producing, for example, a so-called DVD for digital video / universal discs, a method of adhering two disc substrates using an ultraviolet curable composition as an adhesive is used. The ultraviolet curable composition mentioned here includes at least a cationic polyme...
