Description

콘택트렌즈 패키지 검사장치 및 검사방법Contact lens package inspection device and inspection method

구현예는 콘택트렌즈 패키지 검사장치 및 검사방법에 관한 것이다.Embodiments relate to contact lens package inspection apparatus and inspection method.

통상 콘택트렌즈는 콘택트렌즈 주형에 단량체를 주입하고, 고분자 중합을 통해 제조된다. 암형의 주형 내 오목면에 콘택트렌즈 조성물을 주입한 후, 숫형 주형몰드를 상부에서 결합한 다음 소정 시간동안 방치 또는 가열 경화과정을 거쳐, 콘택트렌즈가 형성된다. 제조된 콘택트렌즈는 보관용기(트레이, 홀더 등)에 적재되고, 세척과정 및 비전 검사 등이 진행된다. 비전 검사 후 보관용기에 식염수를 투입하고 밀봉한 다음, 육안 및 현미경 검사 이후 출하된다.In general, contact lenses are manufactured by injecting monomers into a contact lens mold and polymerizing them. After the contact lens composition is injected into the concave surface of the female mold, the male mold is coupled from the top and then left for a predetermined time or subjected to a heat curing process to form a contact lens. The manufactured contact lenses are loaded into storage containers (trays, holders, etc.), and the cleaning process and vision inspection are performed. After vision inspection, saline is put into the storage container, sealed, and shipped after visual and microscopic inspection.

다만, 종래의 콘택트렌즈 검사과정은 밀봉된 상태의 콘택트렌즈 패키지를 검사할 시, 보관용기의 특정 색이나, 내부 식염수 등에 의하여 인식률, 불량 검출율이 저하되고, 과검출이 발생하는 문제점이 있다.However, in the conventional contact lens inspection process, when inspecting the sealed contact lens package, the recognition rate and defect detection rate are lowered by the specific color of the storage container or the internal saline solution, and there is a problem that overdetection occurs.

이러한 문제점을 해결하고, 보관용기에 밀봉된 콘택트렌즈 패키지의 불량을 보다 정확하고 신속하게 파악하기 위하여, 다른 구성 방안에 대해 고려할 필요가 있다.In order to solve this problem and to more accurately and quickly identify the defect of the contact lens package sealed in the storage container, it is necessary to consider another configuration method.
