Patent ID: 8102600

Claim:
A method of manufacturing a stacked disk-shaped optical lens array comprising the steps of: S 1 : providing an injection-compression mold having an upper mold and a lower mold respectively with optical molding surfaces; the upper mold and/or the lower mold is disposed with at least one alignment fixture molding surface respectively and a material inlet is arranged at a center of the upper mold or the lower mold; S 2 : producing a primary product of disk-shaped optical lens array by resin injection-compression molding and cutting off a down sprue stick of the primary product of a disk-shaped optical lens array to produce a disk-shaped optical lens array; the disk-shaped optical lens array having a plurality of optical lens elements formed on optical division while non-optical division of the disk-shaped optical lens array is arranged with at least one glue groove and at least one alignment fixtures; a disk hole is formed at a center of the disk-shaped optical lens array; S 3 : producing another disk-shaped optical lens array by the above steps and this disk-shaped optical lens array is without the glue groove; S 4 : coating glue on the glue groove of the two disk-shaped optical lens arrays for connecting and assembling the two disk-shaped optical lens arrays; S 5 : aligning optical axes of the two disk-shaped optical lens arrays by the alignment fixture so that the plurality of optical lens elements of the two disk-shaped optical lens arrays is aligned with optical center; S 6 : curing the glue to form a stacked disk-shaped optical lens array.
