Problems solved by technology

However, when conducting a high-humidity reliability test on the camera lens module, due to the water absorption of the adhesive material or the small gaps caused by the package, the water vapor enters the lens and cannot escape again, resulting in water vapor in the lens. Condensation of the surface lens will cause the surface of the lens to be blurred, reduce the light transmittance, and seriously reduce the light reflected by the object entering the digital camera module, thereby reducing the optical image signal of the object and making the image sensing element The sensed optical image signal is incomplete, reducing the imaging quality of the image captured by the digital camera

Embodiment Construction

[0014] Referring to FIGS. 1 to 3 , the camera module 100 according to the first preferred embodiment of the present invention includes a lens module 10 and an image sensing device 20 . The lens module 10 includes a lens barrel 12 , a plurality of lenses 14 and spacers (not shown) disposed between adjacent lenses 14 .

[0015] The lens barrel 12 is made of plastic material, which is a hollow cylinder with one end open and the other end semi-closed. The lens barrel 12 includes a light hole 120 and an inner wall 122 . The light hole 120 is located at the center of the semi-closed end of the lens barrel 12, through which external light can enter. At least one arc-shaped groove 124 is formed on the inner wall 122 along the axial direction of the lens barrel 12 , and the groove 124 runs through the inner wall 122 from the semi-closed end of the lens barrel 12 to the open end of the lens barrel 12 . In this embodiment, there are six grooves 124 that are evenly distributed on the in...

This invention provides a kind of camera mould, it includes a lens mould and a image sensing instrument, the lens mould includes a cylinder, multi-lens and the space setting set between the adjacent lens, the lens and the space setting are fixed in the cylinder, the image sensing instrument is set in the imaging surface of the multi-lens, at least set a slot in the lens or the space setting, or between them, the lens, at least a passage is set between the lens, the space setting, the image sensing instrument and the side wall of the cylinder, the slot connects the passage.

Description

technical field [0001] The invention relates to a camera module, in particular to a camera module capable of emitting water vapor and a lens module applied thereto. Background technique [0002] With the development of multimedia technology, digital cameras and video cameras are more and more favored by consumers. People are increasingly pursuing the miniaturization of digital cameras and video cameras. It is hoped that the mobile phone can realize the function of capturing object images and obtain a clear picture, so it is necessary to design and manufacture a digital camera module that can be easily installed in the mobile phone. Due to the small volume of the mobile phone, higher requirements are placed on the volume of the digital camera module installed in it, that is, the volume of the digital camera module used in this mobile phone needs to be smaller, so that it will be photographed The image quality of the object puts forward higher requirements, that is, while the...
