Problems solved by technology
However, since the digital camera lens module adopts an assembled manufacturing method, tolerances of various parts and assembly errors may easily cause problems such as lens eccentricity and lens skew, thereby affecting the optical performance of the digital camera lens module
In addition, when the digital camera lens module is subjected to a reliability test, the optical parts of the lenses 12 and 14 are likely to be dirty due to the outgassing phenomenon of the glue bonded and fixed between the lenses 12 and 14 and the spacer ring 13 and the lens barrel 10 , which in turn affects the optical performance of the digital camera lens module

Embodiment Construction
[0011] Please refer to figure 2 As shown, the digital camera lens module of the present invention includes a lens barrel 20 , a lens 22 , an isolation ring 24 and a lens 26 .
[0012] The lens barrel 20 is cylindrical and made of plastic material. The lens barrel 20 holds the lens 22 , the isolation ring 24 and the lens 26 therein. The lens 22 includes an optical portion 221 and a substrate 222 . The optical part 221 is located in the middle of the substrate 222 and is aspherical. Both sides of the substrate 222 are provided with a positioning groove 223 , which is an annular groove centered on the optical axis of the optical part 221 . The lens 26 includes an optical portion 261 and a substrate 262 . The optical part 261 is located in the middle of the substrate 262 and is aspherical. Both sides of the substrate 262 are provided with a positioning groove 263 , which is an annular groove centered on the optical axis of the optical part 261 and has the same size as the pos...

A method for manufacturing a digital camera lens module, comprising the following steps: providing a plurality of lenses, a plurality of isolation rings and an injection mold, wherein the lenses and the isolation rings are provided with engaging structures correspondingly, and the mold includes a The mold cavity and the two mold cores located in it, the lens and the spacer ring are placed on a mold core in the mold cavity, and the spacer ring is spaced between the lenses, and the engaging structure of the lens and the spacer ring cooperates with each other, and the mold is closed. Press another mold core against the lens, inject plastic, solidify the plastic on the lens and the isolation ring, open the mold and take out the digital camera lens module.
Description
【Technical field】 [0001] The invention relates to a manufacturing method of a digital camera lens module, in particular to a manufacturing method of an integrated digital camera lens module. 【Background technique】 [0002] With the development of multimedia technology, digital cameras and video cameras are becoming more and more popular among consumers. While people are pursuing miniaturization of digital cameras and video cameras, they also put forward higher requirements for the image quality of the objects they shoot. The image of the object to be photographed is clear, and the image quality of the object depends to a large extent on the quality of each optical component in the digital camera, and the manufacturing process of each optical component will also affect its optical performance. [0003] Generally, digital camera lens modules for mobile phones adopt assembly manufacturing methods, such as figure 1 In the digital camera lens module shown, the lens barrel 10 is ...
