Glasses lens plated non-focusing mobile phone camera

Abstract

The invention relates to a mobile camera without focusing and coated lens, which comprises a lens cone, a lens-cone cover with a light-passing hole, a lens in the lens cone, and a photosensitive chip and a printed circuit board at the bottom of the lens cone. The invention is characterized in that, a supporting table is provided around the lower part of the inner wall of the lens cone, on the supporting table, an elastic pressure ring is provided; the lens is on the elastic pressure ring; the surface of the optics of the lens is coated with an infrared ray filter film; around the top of the lens cone, a top table is provided; when the inner surface of the lens-cone cover is tightly pressed on the upper surface of the top table, the optics in the lens are pressed tight and fixed at a correct position due to the fitting between the lens-cone cover and the thread on the lens cone as well as the elastic force of the elastic pressure ring. The structural design allows the lens to be directly fixed on a correct position, so as to eliminate the manual focusing procedure as with the production process for prior mobile camera. The infrared ray filter film coated on the surface of the optics in the lens can eliminate infrared ray filter of special-material glass, and reduce the overall height of the mobile camera, simplify structure and reduce 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...
