Description

t M337077 , [New Technology Area] • This creation is about an optical glass lens set used for assembly between optical glass lenses and clamping rings, especially for small lenses and mobile phone lenses. [Prior Art] An optical lens is the smallest optical component of a camera or a camera lens. It can be composed of one or more optical lenses (〇ptieal lens); the optical lens 2〇a is usually optical plastic or optical. Glass-cutting material made of material, including an optical surface 21a having an optically active surface, which is generally a circular surface; and an outer periphery 22a outside the optical surface 21a. It can be round or square as shown in Figure 1. Generally, in order to enable the optical lens to be fixedly packaged in a lens, the optical lens is first fixed on a holding ring i〇a to form an optical lens set (〇pticaUens set) la. The clamping ring can be made of metal or plastic material. The clamping ring can be used to position and fix the optical lens so that it can be aligned with the central axis of the lens (light_axis), even by an actuator. The clamping ring can be moved within the lens for zooming purposes; for example, US Pat. No. 7,312,933, US 7,095,572, Dislocation 7/0〇24989, and Japanese Patent JP365〇594. The fixing method of the conventional optical or glass optical lens and the clamping ring (which can be made of gold 3 material) is as shown in FIG. 1 , especially the fixing method of the optical glass lens which is made of glass negative I. The shape of the shoulder 22a (such as a circle or a square) = two % 1 〇 a (the shape of the missing ring is not limited to a circle or a square shape), and then the optical cymbal 20a is placed in the clamping ring i 〇 a preset Positioning in the groove, and then sticking with glue 3
