Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a lens module. [Prior Art 3 [0002] A lens module applied to a camera or an optical instrument generally includes a lens barrel, a lens group, a light shielding film, and a filter. Among them, the lens, the light shielding film and the filter are all fixed in the lens barrel. In the assembly process of the lens module, the filter and the lens barrel are fixed by a dispensing process. In the dispensing process, firstly, a lens module to be dispensed is provided, and then the dispensing needle of the dispensing device is placed against the intersection of the filter and the lens tube, and then the dispensing needle is rotated and injected. Glue, so as to apply glue on the inner wall of the filter and the lens barrel: ί+sT..ii .ρ: : 2:.-two two ν _ However, due to the strong fluidity of the glue, when the dispensing needle rotates When the glue is applied to the junction of the filter and the inner wall of the lens barrel, the glue flows easily and the glue overflows, that is, the glue overflows from the junction to the filter, thereby contaminating the filter and reducing the assembly. rate. [0004] In view of the above, it is necessary to provide a lens module that can improve the assembly yield. [0005] A lens module includes a lens barrel, at least one lens, and a filter. And colloids. The lens barrel includes a barrel and a front cover. The cover is disposed on the cylinder. The at least-lens and the calendering sheet are sequentially disposed 111 in the cylinder. The cylinder includes a bottom portion of the cylinder away from the front cover, the filter includes an object side bottom surface, an image side bottom surface opposite to the object side bottom surface, and - the object side bottom surface and the image side bottom surface The side of the body is the same as the body bottom 099134820 Form No. 101 0101 Page 5 / 18 pages 0992060790-0 201215940 [0006] [0008] [0009] 099134820 is provided with at least one opening. The filter is received in the barrel of the barrel and at least one glue-coated area is formed between the side wall of the filter and the opening. The colloid is applied to the at least one glue application zone such that the filter is fixed on the bottom of the barrel of the lens barrel. Compared with the prior art, at least one opening is formed in the bottom of the barrel of the lens barrel of the lens group provided by the present invention. After the filter is housed in the barrel of the lens barrel, the side wall of the filter is A glue application zone is formed between the openings, and the glue is applied to the glue application zone to fix the filter on the bottom of the cylinder of the lens barrel. Therefore, due to the blocking action of the side walls, the colloid does not flow onto the filter, thereby not polluting the filter and improving the assembly yield. The embodiments of the present invention will be further described in detail with reference to the accompanying drawings. Referring to FIG. 1 to FIG. 3, a lens module 100 according to an embodiment of the present invention is provided.
