Abstract
본 발명은 주로 소형 카메라에 적용되는 카메라 렌즈 조립 구조에 관한 것이다.The present invention relates to a camera lens assembly structure mainly applied to small cameras.
종래에는 렌즈2와 렌즈1의 조립시 공기층이 압축되어 렌즈2를 정확한 위치에 고정 시키기 어렵게 되어 제품의 품질을 저하시키게 될 뿐 아니라 푸셔와 스페이서를 사용함에 따라 소요 부품의 수가 증가되어 조립공정이 번잡하게 되고 제조원가를 상승시키게 되며 더우기 세밀한 본딩 작업이 요구되므로 숙련된 작업자가 필요하게 되고 고가의 접착제를 사용함에 따른 제조원가의 부담은 물론 접착제의 사용에 따른 작업환경의 열화가 문제로 되었던 것이다.Conventionally, when assembling the lens 2 and the lens 1, the air layer is compressed to make it difficult to fix the lens 2 at the correct position, which not only degrades the product quality but also increases the number of parts required by using pushers and spacers, which makes the assembly process complicated. In addition, the manufacturing cost is increased, and more detailed bonding work is required, which requires a skilled worker and the burden of manufacturing cost due to the use of expensive adhesives, as well as the deterioration of the working environment due to the use of adhesives.
본 발명은 이러한 문제점들을 해결하기 위하여 안출한 것으로 렌즈2와 배럴의 내경사이에 통상의 형합 공차를 두지 않고 삽입 고정하며 그 외측으로부터 삽입되는 렌즈1은 배럴의 내경을 확장시켜 형성한 정지턱으로된 내경에 삽입함으로써 렌즈2는 배럴의 내경 및 단턱, 그리고 렌즈1에 의하여 위치가 안정된 상태로 고정되도록 한 후 렌즈1과 렌즈3은 열융착공정에 의하여 고정되게 함으로써 완전히 안정된 결합상태를 얻도록하며 렌즈3과 렌즈2와의 사이에 형성된 공간에 외부와 연통되는 통공을 형성하여서 된 것이다.The present invention has been made in order to solve these problems, the lens 2 and the inner diameter of the barrel is inserted and fixed without a normal matching tolerance, and the lens 1 inserted from the outside is a stop jaw formed by expanding the inner diameter of the barrel By inserting it into the inner diameter, the lens 2 is fixed by the inner diameter and step of the barrel and the lens 1 in a stable state, and then the lens 1 and the lens 3 are fixed by the heat fusion process to obtain a completely stable coupling state. The through hole communicating with the outside is formed in the space formed between 3 and the lens 2.
