[Prior Art] [0002] With the continuous development of technology, portable electronic devices, such as mobile phones, are becoming more and more widely used, and at the same time, they are becoming lighter, more beautiful, and more multifunctional. Among them, the camera function is newly developed in recent years. Additional features of the electronic device. Mobile phones with digital cameras are becoming more and more popular among users because of their ability to achieve instant shooting and ease of use. Due to the small size of the mobile phone, the digital camera lens module that needs to be mounted therein has a small volume. While people are pursuing miniaturization of digital camera modules for mobile phones, it is desirable to have higher imaging quality for the objects they are photographing, and the image quality of the objects depends largely on the advantages and disadvantages of the digital camera lens modules. The digital camera lens module generally includes a lens barrel, a lens group, a gasket and a filter. In the assembly process, the lens group, the gasket and the filter are sequentially placed in the lens barrel, and fixed by dispensing. The filter is used to achieve the purpose of fixing the lens group and the gasket. However, the filter is fixed by dispensing. If the glue is too thin, it will penetrate into the lens due to capillary phenomenon, which will affect the optical quality of the digital camera lens module. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide a digital camera lens module that can prevent bleed.

Improve the optical quality of digital camera lens modules. [Embodiment] A preferred embodiment of the present invention discloses a digital camera lens module, which is suitable for a portable electronic device such as a mobile phone. Referring to the first figure, a digital camera lens module according to a first embodiment of the present invention includes a lens barrel 10, a lens group 20, a gasket 30, and a filter 40. The lens group 20, the gasket 30, and the filter 40 are sequentially housed in the lens barrel 10 and fitted to the lens barrel 10. [0009] Referring to the second figure, the lens barrel 10 is a hollow cylinder having an open end and a half-closed end, and a cylindrical receiving cavity 100 is disposed therein. The receiving cavity 100 has a larger diameter section and a larger diameter. The small diameter section is adjacent to the semi-closed end of the lens barrel 10 for receiving the lens group 20 and the gasket 30. The larger diameter section is adjacent to the open end of the lens barrel 10 for receiving the filter 40. The connecting side of the smaller diameter section and the larger diameter section is provided with two spaces 094129237.

The two recesses 110, 120 and the ribs 130 form a blocking structure 140. The blocking structure 140 can accommodate impurities such as glue and other dust that are infiltrated by the filter 40, thereby preventing it from penetrating into the lens group 20. . The lens group 20 is composed of a plurality of lenses. In the first embodiment, the lens set 20 is composed of two lenses 200, 210. [0011] The gasket 30 is a hollow cylinder whose outer diameter is slightly smaller than the smaller diameter of the lens barrel 1 housing cavity 100. The gasket 30 is used to adjust the relationship between the lens group 2〇 and the filter 40. distance. [0012] The calendering sheet 40 is in the form of a disk which can be used to filter light to prevent the image sensor from generating noise, and the outer diameter thereof is slightly smaller than the larger diameter of the lens barrel 1 housing. Different filters 40 can filter light of different wavelengths. In this embodiment, the filter 40 can be an IR_Cut Filter, a Low Pass Filter, or other type. Filter. [0013] When assembling, the lens group 20, the gasket 30 and the filter 40 are sequentially loaded into the accommodating cavity 1 from the open end of the lens barrel 1 ,, and the filter 40 is fixed by dispensing. '4 and fixed lens group 20 and washer 3〇. At this time, the gasket is located between the lens group 20 and the filter 40, and abuts against each other and cooperates with the lens barrel, and the light-passing sheet 40 abuts the ridge 130. In this way, the digital camera lens module is assembled. The dispensing does not contaminate the lens group 20 due to the annular grooves 11 〇, 12 〇 blocking. Referring to the third and fourth figures, the second embodiment of the present invention is substantially the same as the first embodiment described above, except that the washer 5〇 is formed by a large diameter portion 094129237 Form No. A0101 Page 5 / A total of 12 pages 1003393472-0 1362513 On October 24, 100, the replacement page is divided into 500 and a small diameter portion 510. The outer diameter of the large diameter portion 500 is slightly smaller than the smaller diameter of the receiving cavity 100 of the lens barrel 10. After the gasket 50 is inserted into the accommodating cavity 100, the large diameter portion 500 cooperates with the accommodating cavity 100 and abuts the lens group 20, and the end of the small diameter portion 510 abuts the filter 40 and is filtered. The sheet 40 and the accommodating cavity 100 enclose a stop structure 150, which is an annular groove. By the annular groove, the lens group 20 can be stained and stained. [0015] It can be understood that the lens barrel 10, the accommodating cavity 100, the gaskets 30, 50, and the filter 40 are not limited to a cylindrical shape, and may be other shapes. [0016] It can be understood that the accommodating cavity 100 can also have the same diameter; correspondingly, the outer diameter of the filter 40 is slightly smaller than the diameter of the accommodating cavity 100 of the lens barrel 10. In the first embodiment, the gasket The outer diameter of 30 is slightly smaller than the diameter of the receiving cavity 1 of the lens barrel 10. In the second embodiment, the outer diameter of the large diameter portion 500 of the washer 50 is slightly smaller than the diameter of the receiving cavity 100 of the lens barrel 10. [0024] It can be understood that in the first embodiment, the gasket 30 can also be omitted, and the lens group 20 is directly held by the filter 40, or the lens group 20 is interference-fitted with the lens barrel 1.
