[Summary of the Invention]

6 200823593 A lens stack comprising a lens barrel, a filter housed in the lens barrel, a fastening piece, and a fastening ring 'in which the inner wall of the lens barrel is provided with a holding portion for fastening the outer wall of the soil The inner wall of the lens barrel is provided with interfitting threads, and the light-passing sheet abuts against the abutting portion when the fastening screw is engaged in the lens barrel. A lens assembly comprising a lens barrel, a lens module member received in the lens barrel, and a fastening ring, the outer wall of the fastening ring and the inner wall of the lens barrel are provided with a matching thread The fastening ring is threaded into the lens barrel and holds the lens module component in the lens barrel. The lens module assembly is configured to hold the mirror assembly component in the lens barrel, and includes the steps of: providing a fastening ring, the outer wall of the fastening ring and the inner wall of the lens barrel are provided with matching threads The lens module component is assembled in the lens barrel; the fastening ring is threaded to the inner wall of the lens barrel. The lens module uses a fastening ring to package the lens module component in the lens barrel, so that the lens module component, especially the component placed at the end of the lens barrel, for example, the filter can be stably held, avoiding The detachment occurs, and at least the component placed at the end of the lens barrel is protected from glue. [Embodiment] The lens module and the assembling method thereof provided by the present invention will be further described in detail below with reference to the accompanying drawings. / Please - and referring to FIG. 1 and FIG. 2, the lens module (10) provided by the first embodiment of the present invention includes a mirror, a lens 2 received in the lens barrel 1 and a 22' aperture sheet 30. , spacer ring 4 渡, crossing light 5 〇, and a tight 7 200823593 solid ring 60. • The outer wall of the mirror 笱1 设置 is provided with external threads to facilitate connection with a base (not shown) of an image sensing device. The inner wall of the lens barrel 10 is also provided with an internal thread i i at a position close to the end. The lens 21, 22 may be a spherical lens or an aspherical lens, and the aperture plate 30 may be interposed between the lenses 21, 22 to control the size of the luminous flux while also spacing the lens. The role of 21, 22. The spacer ring 40 is used to space the lens 22 and the filter 5, and the filter 50 may be an infrared filter or an infrared-ultraviolet composite filter. Preferably, the inner wall of the lens barrel 1 is further provided with a -# holding portion 12 at a position where the filter is disposed, and the holding portion 12 may be along an annular step of the inner wall of the lens barrel 10 to It is used for the kitchen rim of the light-receiving sheet 50 to be abutted, and the holding portion 12 is adjacent to the internal thread 11 of the inner wall of the mirror cymbal 10. ...

The outer wall of the fastening ring 60 has an outer screw, and the external thread 61 cooperates with the internal thread n of the cylinder 1G to fit the fastening ring (10). By tightening the fastening ring 6〇, the calendering sheet (10) can be solidified on the reading portion 12, so that the positional light sheet 5Q does not need a point and there is no problem of falling off. Preferably, the fastening ring 60 can be glued with the appropriate amount of glue at the threaded portion of the lens barrel 10, and 'turns. AM ensures that the «© ring 60 is not the lens barrel H" and the fastening ring 6Q can be selected, such as a metal such as copper alloy or aluminum alloy, paste _ WW example 4 plastic such as pC / ABS (polypropylene / propylene) Nitrile-butadiene-styrene) I κ propylene column i, polytetrafluoroethylene, and the like. 8 200823593 Both the lens barrel 10 and the fastening ring 60 can be produced by injection molding. When the lens module 100 is assembled, after the lens barrel 10, the lens module component, and the fastening ring 60 are provided, the following steps may be performed: (1) sequentially stacking the above lens modes. The component is in the lens barrel 10; (2) threadedly engages the fastening ring 60 in the lens barrel 10; (3) points a proper amount of glue on the fastening ring 60 and the lens barrel 10 Coordination. The lens module components of the lens module 100 are stacked on each other and the fastening ring 60 is packaged, so that no glue is fixed between the lens module components and the lens barrel 10, and time can be saved. When it is detected that the lens module 100 is poorly assembled, each lens module component can be taken out and reassembled. It can be understood that the lens module components in the lens barrel 10 are stacked in a compact manner, and therefore the positioning portion 12 is not necessarily provided. The φ fastening ring 60 can directly directly couple the lens module components. Hold. Please refer to FIG. 3, which is a schematic diagram of a lens module 200 according to a second embodiment of the present invention. The difference between the lens module 200 and the lens module 100 is that the lens module 200 does not need to use the spacer ring 40, but only needs to be between the lens 21 and the lens barrel 10, and the lens 22 and the lens 21 An appropriate amount of glue is interposed, the filter 50 is abutted against the abutting portion 12, and the other side is fastened by the fastening ring 60, so that the lens module components can be stably held and filtered. The light sheet 50 can avoid the use of glue to reduce the glue contamination. 9 200823593 In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and those skilled in the art will be able to make equivalent modifications or changes in accordance with the spirit of the present invention.
