Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] see figure 1 , is a structural schematic diagram of the pressure ring of the present invention. The present invention provides a pressure ring 10 , which includes a main body 11 , a light hole 12 , a hollow cavity 13 , a through hole 14 , a hole plug 15 , a black filler 16 and an anti-reflection film 17 .

[0028] The main body 11 is made of a transparent material so that more light can pass through its surface.

[0029] The light hole 12 is disposed through the main body 11 , so that the main body 11 forms a ring shape.

[0030] The hollow cavity 13 is embedded in the main body 11 , and the black filling material 16 is filled in the hollow cavity 13 . This structure allows light to be blocked and absorbed by the black filler 16 after passing through the surface of the main body 11 . In this embodiment, more preferably, the black filler 16 is...

Abstract

The present invention provides a junk ring. The junk ring comprises a main body portion, an unthreaded hole penetrating the main body portion, an emptying cavity embedded in the main body portion, and a through hole, a spout plug portion and black stopping which are configured to communicate the emptying cavity with the outside, the spout plug covers the through hole and seals the through hole, and the black stopping is arranged in the emptying cavity. The present invention further provides a processing method of a junk ring and a lens module. Compared to the prior art, the junk ring is good in shading performance and can verify the material light transmission performance, the lens module by employing the lens is good in the optical performance.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to a pressure ring, a processing method of the pressure ring, and a lens module used in the field of photographing and imaging products. Background technique [0002] With the continuous development of science and technology, electronic devices are constantly developing towards intelligence. In addition to digital cameras, portable electronic devices such as tablet computers and mobile phones are also equipped with camera lens modules to meet the needs of users to take pictures at any time . [0003] The lens module of the related art includes a lens barrel, a lens arranged in the lens barrel, a light-shielding sheet or a light-shielding plate clamped between two adjacent lenses, and a pressure plate between the bottom lens and the lens barrel. The pressing ring is fixed to the lens barrel by dispensing glue, so as to realize the fixing of the lens. [0004] However, in the related ...
