| titleOfInvention | Lens spacer manufacture methode using mold for section angle can be formed |
| abstract | The present invention relates to a method for manufacturing a camera lens spacer using a mold capable of forming an angle of a punched slope, and in the process of forming a lens spacer, the inner wall surface of the through hole forms a slope of a certain angle (15-60 °) to reflect light. This is to minimize and thereby improve the lens quality. The present invention for realizing this, in a method for manufacturing a spacer 10 for a camera lens having a through hole 12 in the center, a spacer on the upper surface of the lower mold 100 provided with an inclined portion 103 of a certain angle A film seating step of seating the film S; A punching step in which cutting of the spacer film S is performed by the knife 111 as the upper mold 110 having the knife 111 integrally provided thereon descends; It characterized in that it comprises; a step of forming a cross-sectional angle to form the inclined surface 15 of the predetermined angle (θ) by cutting the spacer film (S) from the lower mold (100). |
