Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a lens module. [0002] 先前 [Prior Art] At present, most lens modules are composed of a plurality of transparent clocks, gauges, aperture plates, and lens barrels. The specific structure of the lens Lin 1 cuts a plurality of lenses and aperture sheets are housed in the lens barrel. The optical image signal entering the lens barrel is focused by the lens and then reaches the image sensor. The image sensor converts the optical image signal into an electronic image signal. At present, the aperture lens used in the miniaturized lens module is a fixed aperture month. Due to the design requirements, the aperture plate is usually added to the image side of the lens closest to the image sensor. Since the thickness of the aperture sheet is relatively thin, it is often picked up by the dispensing needle (electrostatic force) when the adhesive is fixed on the periphery of the aperture sheet, so the image speed is reduced. When the aperture piece is assembled to the lens barrel at the same time, the aperture piece has no positioning point, and it is difficult to maintain the positional accuracy of the aperture piece relative to the lens barrel. Therefore, the assembly yield is low. q [0003] [Summary of the Invention] 1'. In view of this, it is necessary to provide a lens module that can improve the assembly rate and assembly yield: ++:+: v. ' | A lens module includes a lens barrel, at least one lens, and a diaphragm. The lens barrel includes a barrel and a front cover. The front cover is disposed on the cylinder. The barrel includes an inner side wall, and the at least one lens is disposed on an inner side wall of the barrel. The aperture sheet includes a central light transmissive region and a light shielding region surrounding the central light transmissive region. The light shielding area is provided with a plurality of notches away from the edge of the central light transmission area. A plurality of protrusions are formed between the notches. The aperture plate is disposed on the side of the cover at the side of the at least one lens away from the front 098140758 Form No. A0101, and on the inside of the cylinder by the protrusion On the wall. A plurality of gaps are formed between the inner side wall of the face (four) body and the notch of the aperture plate. The gap is filled with a gel to fix the aperture plate to the lens and the barrel. [0007] [0007] Compared with the pre-S technology, the light shielding area of the aperture lens of the lens module provided by the present invention is provided with a plurality of notches and a plurality of notches and cylinders away from the edge of the central transparent area. A plurality of gaps are formed between the inner sidewalls. When the lens module is coated with the colloid, the colloid may flow along the gap between the aperture stop and the image end face of the non-optical portion of the second lens. Therefore, when the click is avoided, the dispensing needle contacts the aperture sheet and is sucked up by the dispensing needle to increase the assembly rate, and the protrusion abuts against the inner side wall of the barrel of the lens barrel to maintain The positional accuracy of the aperture plate with respect to the lens barrel effectively maintains the concentricity of both, which improves the assembly yield.
