Method and apparatus for fusing light-shielding sheets respectively onto transparent bodies

An apparatus for fusing respectively a plurality of light-shielding sheets of a band onto a plurality of transparent bodies, the band further having a connecting unit connected integrally to the light-shielding sheets, said apparatus comprising:

• a fusion unit including
• a base,
• a supporting unit disposed on said base,
• a movable unit disposed directly above said supporting unit and movable toward and away from said supporting unit, the movable unit including a positioning unit adapted to be moved to engage the band so as to position one of the light-shielding sheets relative to said supporting unit, a heating unit adapted to be moved to engage the band so as to fuse the one of the light-shielding sheets onto a corresponding one of the transparent bodies to thereby form an optical lens unit, and a cutting unit adapted to be moved to cut the band so as to remove the one of the light-shielding sheets from the remaining portion of the band, and
• a driving unit for moving said movable unit relative to said supporting unit;
• and
• a plurality of holders, each of which is adapted to receive one of the transparent bodies and is movable onto said supporting unit of said fusion unit.
