[0003] [Prior Art] In the structure of a digital camera lens module, there are generally a lens group, a filter, an image sensor, and the like. The lens group is used for digital camera imaging, and generally has one to several lens sheets. In order to increase the transmittance or wear resistance of the lens sheet, a film is often deposited on the surface of the lens sheet. Filters are used to isolate specific infrared or ultraviolet light to prevent image sensor from receiving noise. 'There is usually anti-reflective (from coating) light and infrared intercept: ..... CUT coating) The filter is mainly made by coating a glass plate and cutting it with a diamond cutter or a grinding wheel. As the size of the digital camera lens module continues to decrease, the numerous internal components affect the volume reduction of the digital camera lens module, and the complexity of the lens module assembly is increased, and the film is smeared on the lens sheet. Extend the manufacturing time of digital cameras. The basic structure of the conventional digital camera lens is as shown in the sixth figure, which is mainly composed of two parts of the lens barrel 2 and the base 3 'where the first lens 4 is mounted on the upper side of the lens barrel 2, and the retaining ring 5 is mounted under the lens 4. For controlling the size of the aperture between the lenses, the second lens 6 is mounted under the retaining ring 5, and the light passing plate 7 is disposed under the second lens 6. A CM0S (Complementary Metal-Oxide Semiconductor) or a CCD (Charge Coupled Device) image sensor 8 is mounted in the base 3. When assembling this lens module, it is necessary to sequentially sequence the image sensor 8, 093137362 Form No. A0101 Page 3 of 11 0993230886-0 1334960
