CARRIAGE ROTATING UNIT OF A VACUUM DEPOSITION DEVICE FOR COATING LENS, CAPABLE OF AUTOMATICALLY COATING BOTH SURFACES OF LENS EVEN IF A WORKER DOES NOT ENTER A VACUUM CHAMBER

摘要

PURPOSE: A carriage rotating unit of a vacuum deposition device for coating lens is provided to simply coat both surfaces of lens since after one surface of the lens is coated, the non-coated surface of the lens is automatically located toward electronic beam by the rotating of a carriage.;CONSTITUTION: A carriage rotating unit of a vacuum deposition device for coating lens comprises a rotary shaft(30), a fixing pin, a stopping piece(32), and a locking pin(42). For a carriage(26) to rotate, the rotary shaft and the fixing pin support the carriage on a rotary disc. The stopping piece is coupled to the end of the rotary shaft and is exposed to the outside of the rotary disc. The locking pin moves forth by the power of a cylinder and enters a vacuum chamber. The stopping piece hangs on the locking pin by the rotation of the rotary disc, the rotary shaft rotates and the carriage rotates on the rotary disc.;COPYRIGHT KIPO 2011
