LENS COATING SYSTEM

摘要

A shaft assembly of a lens coating system includes a first portion reversibly engagable with a second portion. A reciprocating drive disengages and subsequently re-engages the shaft first and second portions. A lens holder is coupled to an arm, which is coupled to the shaft first portion. Another drive, coupled to the shaft second portion, rotates the arm about an axis of the shaft assembly, when the first and second portions are engaged, such that the lens holder travels along a pathway surrounding the assembly. The system includes a plurality of stations, each station having an opening along the pathway, so that the rotating drive may transfer the lens holder into proximity with each station, when the shaft first and second portions are engaged, and the reciprocating drive may transfer a lens, held by the lens holder, into and out from each station through the opening thereof.
