Abstract:
1. A compact disk (DVD) manufacturing machine, comprising: a turntable having eight open-side circular DVD seats, and being controlled via a central shaft to rotate and move upward and downward; and said turntable being circumferentially moved by a distance equal to two said circular DVD seats each time said turntable is rotated; a DVD feeder adapted to simultaneously fetch a first and a second DVD substrate from a substrate feed zone, and lay said first and said second DVD substrate on two adjacent DVD seats on said turntable in the vicinity of said DVD feeder; a glue applicator including two nozzles for dispensing glue separately located above two of said DVD seats that sequentially follow said two DVD seats in the vicinity of said DVD feeder, and two elevating he ads separately located below said two subsequent DVD seats; a DVD laminator including a movable sucker mounted on a pivoted arm pivotally rotatable by a motor, and a fixed sucker; said two suckers being located below two of said DVD seats that sequentially follow said two DVD seats in the vicinity of said glue applicator, and adapted to suck and laminate said first and said second DVD substrate; and a DVD collecting station for drying glue dispensed by said glue applicator between said first and said second DVD substrate, and collecting a compact disk obtained from said first and second DVD substrates laminated at said DVD laminator; said glue applicator being adapted to apply glue on said first and said second DVD substrate at the same time, so as to form a raised glue ring on a laminating surface of each of said first and second DVD substrates; and said DVD laminator being adapted to pivotally turn said first DVD substrate toward said second DVD substrate at a high speed, and then slow down before said first DVD substrate gets in touch with said second DVD substrate to allow said glue rings on said laminating surfaces of said two DVD substrates to contact with each other first, and then slow down again for said two DVD substrates to laminate; and said DVD laminator including a rotating element located below said fixed sucker and adapted to rotate said laminated DVD substrates to ensure even spreading and distribution of said applied glue between said two DVD substrates without producing blisters.
