Description of the Invention: - Technical Field of the Invention The present invention relates to a lens structure', particularly to a miniaturized lens that prevents spillage during production. [Prior Art] Referring to FIG. 1 and FIG. 2, there is a lens 1 installed in a camera phone (not shown). The lens 1 has a lens barrel 11, a lens unit 12, and a fixed pressure ring 13. . The lens barrel 11 has a peripheral wall ill surrounding an axis L, and a chamber 112. The peripheral wall 1 π has a first opening Π 3, a second opening 114, and a stepped inner peripheral surface 115. The lens unit 12 is disposed in the chamber 112. The first opening, the second opening, and the second opening ι14 are sequentially a first, second, third, and fourth lenses 121, 122, 123, and 124, respectively. The lenses 121, 122, 123, 124 abut each other. After the fixed pressure ring 13 abuts against the first lens 121, a glue is adhered to the fixed pressure ring 13 and the inner circumferential surface 115 to fix the lens unit 12 to the lens barrel. 11 inside. In the case of a miniaturized lens, since the lens 1 itself has a small volume, the optical effective diameter φ of the lens unit 12 is relatively small, so that a light-receiving element (not shown) in the camera phone receives light. Less and have lower shooting quality. When the lens unit 12 is pressed by the fixed pressure ring 13 , the lens unit 12 is designed to be reserved for the fixed pressure ring π between the optical effective path 内 and the inner circumferential surface 115 of the lens barrel 11 . a preset width D. In this case, if the optical effective diameter φ is to be increased, only the diameter of the 5200823510 lens 1 can be increased, which will increase the volume of the lens 1; otherwise, if the lens is to be used In the case of miniaturization, the optical effective diameter φ can be sacrificed, and the reduction in size of the lens 1 and the large optical effective diameter φ cannot be achieved. Moreover, in the dispensing process, the adhesive 14 is usually adhered to the fixed pressure ring 13 and the inner circumferential surface 115, but the adhesive 14 overflows frequently to be optically effective to the first lens 121. Within the diameter φ, the lens 1 image is poor and the production yield is lowered. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a miniaturized lens that can prevent spillage during production. Still another object of the present invention is to provide a lens which is more compact. A further object of the present invention is to provide a miniaturized lens which can increase the optical effective diameter without increasing the outer diameter of the lens barrel.

The miniaturized lens of the present invention, the adhesive 5 is an outer ring surface 311 contacting the first lens 31, and is not optically effective. The same side end face, because of this spring, can greatly reduce the occurrence of overflow glue in the optical effective diameter Φ 。. In addition, it is only necessary to dispense the four dispensing grooves 217 without a full circle of dispensing. 'The amount of the adhesive 5 can be reduced. 2. Since each glue groove 217 is defined by the first, second, and third faces 214, 215, 216 and the outer ring surface 311, The lens 5 can be directly dropped into the dispensing tanks 217 to fix the lens unit 3. As shown in Figures 1 and 3, compared to the conventional technique. Therefore, the present invention does not need to additionally use the fixed pressing ring 13 to fix the lens and provide the dispensing platform. Therefore, the optical effective diameter Φ1 of the mirror early in the present invention and the inner peripheral surface 211 can be smaller. Therefore, the lens barrel 2 having a smaller outer diameter than the conventional lens barrel U can be used to make the lens more compact, or to maintain the outer diameter of the lens barrel 2 of the present invention and the conventional mirror.
