Abstract: A de-taping machine for removing a tape around a lens-mold-assembly. The machine including a lens-mold-assembly-rotation mechanism for holding and rotating the lens-mold-assembly and a tape gripping mechanism. The tape gripping mechanism including a first jaw having a clamping surface; a second jaw movable towards the first jaw for clamping a free end of the tape; a proximity sensing arrangement to generate a first detection signal when the free end of the tape is at a pre-determined distance from the first jaw; and a contact sensing arrangement to generate a second detection signal when the tape is in contact with the first jaw. A rotational speed of the lens-mold-assembly-rotation may be varied based on the first detection signal. Further, the lens-mold-assembly-rotation mechanism may be stop and the tape gripping mechanism may move the second jaw for clamping based on the second detection signal. A corresponding method for tape removal.

Abstract: A deflashing machine (100) including a lens-mold-assembly-rotation mechanism (110) having a coaxially aligned first and second rotary parts (112, 114). The first and second rotary parts (1112, 114) being operable for holding the lens-mold-assembly (102) therebetween, and rotatable about a common axis (113). The machine further includes a deflashing mechanism (120) having a first blade (130) and a second blade (140) disposed at a first radial position and a second radial position from the common axis (113) respectively. The first blade (130) having a trimming edge (132) parallel to the common axis (113) for engaging a circumferential surface of the lens-mold-assembly (102) held between the first rotary part (112) and the second rotary part (114).
