Embodiment Construction

[0008] Such as figure 1 with figure 2 As shown, the optical lens of the present invention includes a curved surface of the lens and an outer diameter of the lens, the outer diameter of the lens is integrally formed with the curved surface of the lens, and the movable side of the outer diameter of the lens is composed of a straight section 1, a slope 2 and a connecting part 3 , the length of the straight section 1 is 0.08 mm to 0.2 mm, the demoulding slope of the slope 2 is 5° to 30°, and the radius of curvature of the connecting portion 3 is 0.05 to 0.1. During specific implementation, the length of the straight segment of the lens is 0.1 mm, the demoulding angle of the inclined surface is 15°, and the radius of curvature of the connecting portion is 0.08.

[0009] Control the length of the straight section 1 on the movable side of the outer diameter of the lens (also known as the male mold) within the range of 0.08mm to 0.2mm, and set the demoulding slope of 5° to 30° on th...

Abstract

The invention relates to an optical lens. The optical lens comprises a lens curve surface and a lens external diameter. The lens external diameter is integrated with the lens curve surface. A movableside of the lens external diameter consists of a straight segment, an inclined plane and a connection part. The length of the straight segment is 0.08mm-0.2mm; a draw taper of the inclined plane is from 5 degrees to 30 degrees; and a radius of curvature of the connection part is from 0.05-0.1. Through the design on the lens external diameter, the optical lens of the invention can solve the problemthat the optical lens is not easy to release and easy to get damaged during a releasing process, causing big shape deformation and asymmetry on an optical effective surface of the lens.

Description

technical field [0001] The invention relates to the technical field of mobile phone cameras and digital cameras, in particular to an optical lens. Background technique [0002] With the current development of the mobile phone market and digital camera market, the pixel of the lens is getting higher and higher, so the quality requirements for the internal components of the lens, such as the lens, are also getting higher and higher. In order to ensure the eccentricity of the lens, most of our lenses are molded in one piece at present, that is, the outer diameter and the curved surface of the lens are processed in one piece. However, when the integral mold is formed, it is not easy to release the mold, and it is easy to pull the mold, which causes problems such as large deformation and asymmetry of the optical effective surface of the lens. In order to obtain a better quality lens surface shape, it is necessary to improve the problem of the mold drawing of the lens during mold...
