Embodiment Construction

[0017] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] see figure 1 and figure 2 , the lens module 100 provided in this embodiment includes a first frame member 110 , a first lens 120 , a second frame member 130 , and a second lens 140 .

[0019] The first frame member 110 has a first stepped through hole 112 inside, and a protrusion 114 is formed inside the first stepped through hole 112 for resisting the lens.

[0020] The first lens 120 is fixed in the first stepped through hole 112 of the first frame member 110 by ultraviolet glue, shadowless glue, quick-drying glue or white resin glue. One end of the first lens 120 leans against the protrusion 114, and the other end is provided with a support body 150, which can prevent the first lens 120 from being unstable due to vibration during the use of the lens module 100 and causing the lens Phenomena such as deterioration of the optical...

Abstract

The invention provides a lens module group, comprising a first frame part with a first step via hole, at least a first lens fixed in the first step via hole; a second frame part with body part, end part and a second step via hole through the body part and the end part, the second frame part passes through the first step via hole of said first frame part on the axial direction of the second step via hole and is matched with the first frame part tightly, the second frame part can rotate relatively to the first frame part, at least a groove is formed at the end of said second frame part and the groove is used to match a treatment tool so that the second frame part can rotate relatively to the first frame part; and at least a second lens fixed in the second step via hole, the second lens rotates relatively to the first frame part along with the second frame part. The lens module group structure is compact and the invention also provides the assembling method for the lens module group.

Description

technical field [0001] The invention relates to a lens module and an assembly method thereof. Background technique [0002] Compared with general optical instruments, the structure of the camera lens is more complex, often composed of a considerable number of lenses. In optical design, the relative positions of these lenses are designed as a completely ideal situation, that is, the image quality during design is completed under the ideal condition that the optical axes of each lens are completely coincident, and each lens There is no concentricity error. But generally, when assembling the lens, the optical axis of each lens will have different degrees of inclination or deviation when it is loaded into the lens barrel, resulting in concentricity errors, which will inevitably affect the imaging quality of the assembled lens. Therefore, for a good lens, it should not only have a reasonable lens barrel design, but also should be assembled with a good assembly method to minimiz...
