Abstract

The invention discloses a repeatedly packaging lens construction and a production method thereof. The camera lens comprises a lens cone, a lens set and an optical filter, wherein the inner cavity of the lens cone is provided with a light-vent hole, lens space and optical filter space which are coaxial-core and are communicated with each other; the lens set is arranged in the lens space; the bottom of the lens space protrudes an edge out of an axis core to package the lens set; and the optical filter is arranged in the optical filter space. In the invention, the lens set and the optical filter are respectively packaged, thereby having simple structure and low production cost; a production worker can package and measure the lens set firstly, at that time whether a finish product of the lens is suitable for a visible region or a black light region, an ordinary measuring method can be used to carry out measuring, then the optical filter is packaged to obtain a finish product. The invention greatly simplifies the production and measuring process and improves the work efficiency.

Description

(1) Technical field:

[0001] The invention relates to a lens structure which is encapsulated many times in the production process, and the lens structure is suitable for both the visible light area and the invisible light area. (two) background technology:

[0002] existing lenses such as figure 1 As shown, it generally includes lens barrel A, lens group B, and optical filter C. The inner cavity of the lens barrel is provided with an accommodating space D, and components such as lens group B and optical filter C are closely attached to and fixed in the accommodating space D. The encapsulation of the lens generally adopts a single hot melt or glue dispensing, and the encapsulation of the lens is generally tested by a projector for its resolution capability. However, some special cameras used in the invisible light region, such as infrared cameras, have obvious defects in this lens structure. Because the filter in the lens can only pass through light of a specific wavelength,...

Embodiment Construction

[0027] like Figure 2 to Figure 5 As shown, the present invention includes a lens barrel 1, a lens group 2 and an optical filter 3, wherein, the inner cavity of the lens barrel 1 is sequentially provided with a coaxial and interconnected optical hole 6, a lens space 4 and an optical filter space 9 , the lens group 2 is installed in the lens space 4 , the bottom of the lens space 4 protrudes toward the axis with a wrapping 5 enclosing the lens group 2 , and the optical filter 3 is installed in the optical filter space 9 .

[0028] In the present invention, the lens group and the optical filter are packaged separately, the structure is simple, and the production cost is low; the production personnel can first package and test the lens group. The detection method is used for detection, and then the filter is packaged to obtain the finished product. This greatly simplifies the production and testing process and improves work efficiency.

[0029] The bottom of the above-mentioned...
