Patent ID: 8491748

Claim:
A gluing method for assembling an optical transceiver module, comprising: (1): providing a substrate, a lens and a lens barrel, the lens barrel being symmetrical about a center axis and comprising a top surface, a bottom surface, and an inner surface, the bottom surface opposite to the top surface and mounted on the substrate, the lens comprising an upper surface; (2): providing a rotatable platform to hold the substrate, the rotatable platform having a rotating axis, the rotating axis being coaxial with center axis; (3): positioning the lens in the lens barrel, with the upper surface being lower than the top surface relative to the substrate; (4): providing a gluing syringe containing glue, the gluing syringe comprising a syringe needle for outputting the glue; (5): positioning the gluing syringe above the upper surface and keeping the syringe needle without contacting the upper surface and the inner surface; (6): moving the gluing syringe toward the lens such that the syringe needle being closer to the substrate relative to the top surface and the syringe needle yet without contacting the upper surface; (7): moving the gluing syringe toward the inner surface until the syringe needle in contact with the inner surface; (8): pressing the gluing syringe to output the glue through the syringe needle and rotating the rotatable platform.
