Abstract

A de-taping machine for removing a tape around a lens-mold-assembly is disclosed. The machine includes 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 mechanism may be varied based on the first detection signal. Further, the lens-mold-assembly rotation mechanism may be stopped and the tape gripping mechanism may move the second jaw for clamping based on the second detection signal. A corresponding method for tape removal is also disclosed.

Description

technical field [0001] Various embodiments generally relate to a tape removal machine for removing tape from a lens mold assembly. In particular, various embodiments relate generally to a tape removal machine for removing tape around the perimeter of a lens mold assembly. Various embodiments also relate to a method of removing tape from a lens mold assembly. In particular, various embodiments relate generally to a method of removing tape around the perimeter of a lens mold assembly. Background technique [0002] Conventional methods of lens manufacturing are typically via manual processes. Typically, liquid molding material is manually filled into the mold cavity between the two shells while tape holds the two shells together along their perimeters to form the molded lens between the shells. Subsequently, the tape is manually removed and the two shells are manually separated from the molded lens to retrieve the molded lens. The manual tape removal process typically invol...
