Glass lens array module with alignment member and manufacturing method thereof

A manufacturing method of glass lens array module comprising the steps of:

• providing a glass blank;
• providing an upper mold and a lower mold for forming a glass lens array, wherein the upper and lower molds respectively are disposed with a plurality of mold cores of optical surfaces and mold pins and/or mold bushings of alignment members;
• setting the glass blank into a mold cavity formed by the upper mold and the lower mold so as to be heated and pressured for carrying out a molding process to mold a first glass lens array having a plurality of optical area as well as a plurality of alignment members disposed on non-optical area;
• repeating above steps to produce a second glass lens array;
• coating glue on the non-optical area of the first glass lens array and of the second glass lens array;
• assembling the first glass lens array and the second glass lens array by the alignment members;
• curing the glue to form a glass lens array module.

A manufacturing method of glass lens array module comprising the steps of:

• providing a glass blank;
• providing an upper mold and a lower mold for forming a glass lens array, and the upper and lower molds respectively disposed with a plurality of mold cores of optical surfaces, and mold straight leaders and/or mold straight sleeves for forming through holes;
• setting the glass blank into mold cavity formed by the per mold and the lower mold so as to be heated and pressured for carrying out a molding process to mold a first glass lens array having a plurality of optical area as well as at least one through hole disposed on non-optical area;
• repeating above steps to produce a second glass lens array;
• putting the second glass lens array into an assembly fixture with at least one assembly center shaft, and the through hole of the second glass lens array is inserted by the assembly center shaft coating glue on the non-optical area of the second glass lens array;
• putting the first glass lens array into the assembly fixture, and the through hole of the first glass lens is inserted by the assembly center shaft for alignment;
• and
• curing the glue and releasing the assembly fixture to form a glass lens array module.
