Glasses lens plated non-focusing mobile phone camera

Abstract

The invention relates to a lens coating non-focusing mobile phone camera, which comprises a lens barrel, a lens barrel cover with a light hole and a lens group arranged in the lens barrel, and a photosensitive chip and a printed circuit board are arranged at the bottom of the lens barrel; it is characterized in that There is a support platform surrounding the lower part of the inner wall of the lens barrel, and an elastic pressure ring is arranged on the support platform. The lens group is placed on the elastic pressure ring, and the lens surface of the lens group is coated with an infrared filter film; the top of the lens barrel is provided with a top When the inner surface of the lens barrel cover is tightly pressed with the upper surface of the top platform, the lens in the lens group is compressed and fixed in the correct position by virtue of the threaded fit of the lens barrel cover and the lens barrel and the elastic force of the elastic pressure ring. . This structural design can directly fix the lens group at the correct position, thereby omitting the manual focus procedure in the traditional mobile phone camera production process. Coating the infrared filter film on the lens surface of the lens group can save the infrared filter made of special material glass, reduce the overall height of the camera of the mobile phone, simplify the structure and reduce the cost.

Description

technical field [0001] The invention relates to a mobile phone camera, in particular to a lens coating non-focusing mobile phone camera. Background technique [0002] At present, most mobile phone cameras use fixed-focus optical lens groups. During production, the lens group needs to be adjusted to the best position away from the photosensitive chip by the threaded cooperation between the lens barrel and the sleeve. The existing structural design often results in time-consuming and laborious production operations. And the product precision is low. In addition, in order to prevent the interference of infrared rays on the photosensitive chip, it is necessary to add a glass of special material and coat a layer of infrared filter film on the surface, which makes the structure more complicated and increases the volume, which is not conducive to simplifying the process, and will also Increase production costs. Therefore, improving the structure of the existing mobile phone camer...
