Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a lens module, and to a method of assembling a lens module. [Before the 彳 branch f] [0002] With the development of multimedia technology, electronic products with camera functions are increasingly favored by consumers, and people are shooting objects while pursuing miniaturization of electronic products. The image quality puts forward higher requirements, that is, the image of the object to be photographed is clear. [0003] At present, the camera module of most electronic products includes a lens barrel and a first lens, a spacer ring and a second lens mounted in the lens barrel. One end of the barrel extends inwardly to form an annular stop. The first lens, the spacer ring and the second lens are sequentially received in the lens barrel, wherein the first lens abuts against the blocking portion, the spacer ring is used for isolating the first lens and the second lens, so that the first lens and the second lens A certain distance between them to meet the needs of the optical design of the lens module. The outer diameter of the second lens is smaller than the inner diameter of the lens barrel. When the lens module is assembled, the first lens and the spacer ring are sequentially placed in the lens barrel, and the first lens is abutted against the stopping portion of the lens barrel, and then a needle-shaped injection portion is used. The glue applicator is coated with UV glue (Ultraviolet glue) on the outer circumference of the spacer ring away from the surface of the first lens, and then pressed into the second lens, and then the UV glue is cured by ultraviolet light irradiation to fix the second lens. In the lens barrel, the components in the lens barrel are fixed between the stopper portion of the lens barrel and the second lens. [0004] In order to fix the second lens in the lens barrel more stably, the glue is usually dispensed on the surface of the spacer ring. The amount of glue is not easy to control. On the one hand, at 098144339, the form number A0101 is page 4 / 19 pages 098 201122609 When the uv glue is cured by ultraviolet light after entering the second lens, the phenomenon of easy overflowing occurs, and the action of the liquid siphon causes the second lens to float toward the end away from the stop. Therefore, the concentricity between the assembled first lens, the second lens and the lens barrel is difficult to determine, which affects the imaging quality of the entire lens; on the other hand, it is easy to cause unevenness of the knees everywhere, resulting in the second lens and The bonding between the lens barrel and the spacer ring generates stress. Under long-term use, the second lens is easily detached from the lens barrel and the spacer ring, and the camera lens module cannot be used.
