Claim 14:
15. A method of disassembling an lens mold assembly comprising a first mold part, a second mold part, and a molded-lens sandwiched between the first mold part and the second mold part, the method comprising:
pushing and aligning the lens mold assembly laterally to a pre-determined position in a centering-movement plane via a centering unit having at least two pusher members movable relative to each other along the centering-movement plane to converge towards the pre-determined position;
clamping the lens mold assembly via a mold engagement mechanism having a first engagement member and a second engagement member movable towards each other to provide a first clamping action along a first clamping-axis perpendicular to the centering-movement plane such that the first and second engagement members are respectively engaged with the first and second mold parts;
detecting, via a sensor of an alignment guidance module, relative positions, along a movement direction parallel to the first clamping-axis, between the molded-lens of the lens mold assembly held by the first and second engagement members and a second clamping-axis of at least two clamping members of a molded-lens holder mechanism which is parallel to the centering-movement plane, the at least two clamping members movable towards each other to provide a second clamping action along the second clamping-axis parallel to the centering-movement plane;
moving the lens mold assembly held by the first and second engagement members, via a processor configured for moving the first and second engagement members in a synchronous manner along the movement direction, for aligning the molded-lens of the lens mold assembly with the second clamping-axis of the at least two clamping members of the molded-lens holder mechanism based on the detected relative positions;
clamping the molded-lens of the lens mold assembly via the at least two clamping members of the molded-lens holder mechanism by urging the at least two clamping members against respective opposite side surface segments of the molded-lens;
separating the first and second mold parts from the molded-lens held by the at least two clamping members of the molded-lens holder mechanism via holding the first and second mold parts independently by the first and second engagement members of the mold engagement mechanism respectively and moving the first and second engagement members away from each other in opposite directions.
