Abstract
There is provided a method of curing an optical disc capable of effectively curing the optical disc without generating a warp phenomenon when optical disc is cured while ultraviolet curing resin material is irradiated with ultraviolet. The method of curing an optical disc comprises overlaying first and second resin substrates onto each other by way of an adhesive made of ultraviolet curing resin material, the method further comprising clamping the optical disc by ultraviolet transmittance plates at both sides thereof, and curing the adhesive while being irradiated with ultraviolet from outside of the ultraviolet transmittance plates.
Claims10
An apparatus for curing an optical disc, comprising:
- first and second resin substrates, said first resin substrate being overlaid on said second resin substrate by way of an adhesive;
- two ultraviolet transmittance plates for clamping said first and second overlaid substrates therebetween;
- a base table for supporting said two ultraviolet transmittance plates;
- conveying means for moving said base table;
- and
- ultraviolet irradiators for irradiating said first and second overlaid substrates on said base table with ultraviolet radiation from both sides thereof to cure the adhesive and thereby produce an optical disc.
An apparatus for joining first and second substrates by an ultraviolet-cured adhesive into a substantially warp-free optical disc, comprising:
- first and second plates respectively clamping said first and second substrates therebetween, said first and second plates being transparent to ultraviolet radiation, said first plate clamping downwardly on an upper surface of said first substrate and having a central bore therethrough, said second plate clamping upwardly on a lower surface of said second substrate and having a boss extending upwardly through a bore portion of the first and second substrates into said central bore of said first plate;
- a base supporting said first and second plates with the first and second substrates therebetween;
- and
- ultraviolet irradiators irradiating through both said first and second plates to cure the adhesive joining the first and second substrates as clamped between said first and second plates.
An apparatus for joining first and second substrates by an ultraviolet-cured adhesive applied therebetween to create a substantially warp-free optical disc, comprising:
- first and second plates clamping the first and second substrates therebetween, said first and second plates being transparent to ultraviolet radiation;
- a base supporting said first and second plates with the first and second substrates therebetween and orienting the first substrate above the second substrate;
- a first ultraviolet irradiator irradiating from above through said first plate to cure the adhesive joining the first and second substrates;
- and a second irradiator irradiating from below through said second plate to cure the adhesive joining the first and second substrates.
