Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0027] Such as Figure 1-2 As shown, the present invention provides a lens barrel 10, which includes a barrel wall 1 having a receiving space 11, a light-through hole 2 disposed at one end of the barrel wall 1 near the object side, and embedded in the barrel wall 1. The inner cavity 3 , the through hole 4 , the hole plug part 5 and the black material 6 .
[0028] The cylinder wall 1 includes a main cylinder wall 12 and an auxiliary cylinder wall 13 extending from an end of the main cylinder wall 12 close to the object side to the direction of the optical axis, both of which together form the accommodating space 11 .
[0029] The light through hole 2 is set through the auxiliary cylinder wall 13 , and the light through hole 2 is arranged on the auxiliary cylinder wall 13 .
[0030] The hollow cavity 3 includes a first hollow cavity 31 and a second holl...

The invention provides a lens barrel, including a barrel wall having a housing space, a light through hole arranged at one end of the barrel wall close to an object side, an emptying cavity embedded in the barrel wall, a through hole and a hole plug part. The emptying cavity is arranged close to the inner side of the barrel wall and is filled with black material, the through hole connects the emptying cavity with the outside world, and the hole plug part is arranged at the through hole and seals the through hole. The invention provides a method for processing a lens barrel and a lens module using the lens barrel at the same time. Compared with related technologies, the lens barrel and the processing method thereof enable the lens barrel to have the performance of blocking stray light, thereby enabling optical performance of the lens module using the lens barrel to be good.
Description
technical field [0001] The invention relates to the field of optical imaging, in particular to a lens barrel, a processing method of the lens barrel and a lens module used in the field of photographing and video recording 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 relat...
