Field of the Invention The present invention relates to a lens module and a method of fabricating the same, and more particularly to a lens module of a filter and a method of fabricating the same. Eighty-eight [previous technology] With the development of optical imaging technology, the lens module has been widely used in various imaging events such as digital cameras and video cameras, and electronic devices such as mobile phones and notebook computers integrated with the mirror group have been obtained. A common lens module for many consumers usually includes optical elements such as lenses, apertures, #, filters, etc., which are housed in the lens barrel, and spacers for (4) spacing of various optical elements. In the assembly process of the lens module, optical elements such as the lens, the aperture plate, and the filter are sequentially housed in the lens barrel, and the filter and the adjacent lens are separated by a spacer. The filter is glued to the spacer by a dispensing process. • Silk technical towel, which is laminated by the following manufacturing method. A lens barrel is provided, and a spacer is disposed in the lens barrel. First in the spacer ^ point UV curing glue (uv glue). The filter is placed in the lens barrel by pushing, etc., and the spacer is abutted by the UV glue, and the solid tuv glue is irradiated by ultraviolet light, thereby bonding the filter and the spacer to obtain a lens module. However, during the curing process, the filter blocks most of the UV light. For the Infrared-Cut Filter, although theoretically only blocking the infrared band in the incident light, only 2% to 5% of the ultraviolet light can actually pass. Such a solid tUV adhesive takes a long time, or 6 200815907, a part of the uv glue does not fully cure. As a result, the filter between the filter and the spacer is insufficient. The filter is easily detached from =, resulting in _ _ _ failure. M + [Summary of the Invention] In view of the above, it is necessary to provide a lens module and a method of manufacturing the same, so that the filter is not easily detached from the lens module. A lens module includes a lens barrel, a spacer disposed in the lens barrel, and a filter disposed on the spacer, the bottom surface of the filter passes through the cured first ultraviolet curing adhesive and The spacer is glued, and the side wall of the filter is glued to the barrel by the cured second ultraviolet curable glue. A lens module includes a lens barrel, a spacer disposed in the lens barrel, and a filter disposed in the spacer, the spacer having a recessed structure for receiving the lens a filter that is glued to the spacer by a cured first UV curable adhesive, the sidewall of the filter being further glued to the spacer by a cured second UV curable adhesive. A manufacturing method of a lens module, comprising the steps of: providing a lens barrel, wherein a spacer is disposed in the lens barrel, and the first ultraviolet curing adhesive is coated on the spacer; and a filter is placed in the lens barrel. The bottom surface of the filter is abutted against the spacer by the first ultraviolet curable adhesive; a second ultraviolet curable adhesive is applied to the gap between the filter and the lens barrel; and the second ultraviolet is cured by ultraviolet light irradiation. Curing the glue to obtain the lens module. A manufacturing method of a lens module, comprising the steps of: providing a lens barrel, wherein the lens barrel is provided with a spacer body, and the spacer body has a recessed junction 7 200815907 ^ The recessed structure is used for accommodating the filter, The spacer is coated with a first f-ultraviolet-curable adhesive; a filter is placed in the recessed structure of the spacer - the bottom surface of the filter is abutted against the spacer by the first ultraviolet-curable adhesive; Applying a second ultraviolet curable adhesive to the gap between the filter and the lens barrel; and curing the second ultraviolet curable adhesive by ultraviolet light irradiation to obtain a lens module. Compared with the prior art, the sidewall of the filter is further glued to the lens barrel or the spacer by the cured second UV-curable adhesive, thereby improving the filter between the light sheet and the lens barrel or between the filter and the spacer. The adhesion between the bodies makes it difficult for the light-passing sheet to fall off from the lens module, thereby improving the quality of the lens module. In the manufacturing method, the second ultraviolet curable adhesive is directly irradiated by ultraviolet light to cure, thereby improving the adhesion between the filter and the lens barrel or between the filter and the spacer. The film is not easy to fall off from the lens module, and the quality of the lens module is further improved. Moreover, the second ultraviolet curable adhesive can be cured faster by direct irradiation with ultraviolet light, thereby improving the production efficiency of the lens module. * Embodiments Hereinafter, embodiments of the present invention will be further described in detail with reference to the accompanying drawings.
