The application is further described below in conjunction with specific embodiment.
Fig. 1 is the dimensional structure diagram of the anti-dazzling screen 10 according to presently filed embodiment.In the art, anti-dazzling screen
10 alternatively referred to as camera lens darkening ring, shading pads, and after available stainless steel material is through overetch and blackening process, it is embedded in camera lens
In play interception.
As shown in figure 1, the anti-dazzling screen 10 according to presently filed embodiment includes body 100 and through hole 103.Body 100
Can be formed after overetch and blackening process by stainless steel material.Through hole 103 is located at the center position of anti-dazzling screen 10 and insertion
Body 100, for making light pass through body 100.Through hole 103 can be punching.In one embodiment, through hole 103 can be tool
There is the manhole of one side chamfering shape, image in imaging is projected to after the inner ring surface of anti-dazzling screen such that it is able to effectively reduce light
It is middle to produce serious reflected light line.
Body 100 has first surface 101 and the second surface 102 relative with first surface 101.Set on anti-dazzling screen 10
Label layer 104 is equipped with, for aiding in carrying out the correct positive and negative for judging anti-dazzling screen 10.Label layer 104 may be disposed on first surface,
And be may be disposed on second surface with the color of the surface color different from first surface, or label layer 104, and with not
It is same as the color of the surface color of second surface.That is, when label layer 104 is arranged on first surface, label layer 104
Color can be first surface surface color beyond any color, when label layer 104 is arranged on second surface,
The color of label layer 104 can be any color beyond the surface color of second surface.It is worth noting that, can only be
Label layer 104, the color of label layer 104 and the table of anti-dazzling screen 10 are set in the wherein one side of one surface 101 and second surface 102
Color distortion between face color should meet the identification of automatic assembly equipment.By automatic assembly equipment to label layer 104
Identification, can correctly judge the positive and negative of anti-dazzling screen 10, so as to the correctness for contributing to lifting to assemble, assemble anti-dazzling screen 10
There is foolproof function in journey.
Used as an example, the surface color of anti-dazzling screen 10 can be black, and the color of label layer 104 can be for beyond black
Any color.
According to presently filed embodiment, the label layer 104 being arranged on first surface 101 or second surface 102 can be
Colour band, or can be other patterns that are colored, being identified, for example, the pattern such as strip, triangle, circular or starlike.
Fig. 2 is the profile of the anti-dazzling screen 10 according to presently filed embodiment.
Referring to Fig. 2, the anti-dazzling screen 10 according to presently filed embodiment has first surface 101, second surface 102, interior
Anchor ring 106 and outer ring surface 105.Inner ring surface 106 connects the inward flange of first surface 101 and second surface 102, and around formation
Through hole 103.As shown in Fig. 2 inner ring surface 106 can be inclined from the inward flange of second surface 102 to the inward flange of first surface 101.
Outer ring surface 105 connects the outward flange of first surface 101 and second surface 102.
As an example, the thickness H of label layer 1041H can be met1≤ 0.003mm, for example, H1H can further be met1
≤0.001mm。
Additionally, the distance between the thickness of anti-dazzling screen 10, i.e. first surface 101 and second surface 102 H can meet 0.01mm
≤ H≤0.2mm, for example, H can further meet 0.015mm≤H≤0.05mm.
Fig. 3 is the floor map of the anti-dazzling screen 10 according to presently filed embodiment.
As shown in figure 3, label layer 104 partly covers first surface 101.Similarly, label layer 104 also can partly be covered
Lid second surface 102.It is unfavorable for automatic assembly equipment in identification process to label layer it should be understood that label layer area crosses conference
Differentiation.The label layer of suitable area contributes to the identification of automatic assembly equipment.In an implementation method of the application, mark
The area S of the layer 104 and area S of first surface1Or the area S of second surface2S≤2/3S can be met1；Or S≤2/3S2。
Used as an example, body 100 has the shape of annulus, and label layer 104 is in the direction of the radial direction perpendicular to body
On, extend greater than equal to 0.05mm apart from W, it is identified in order to automatic assembly equipment, for example, one can be entered apart from W
Step meets 0.15mm≤W≤0.2mm.
As an example, the outer diameter D of body 1001With the minimum diameter D of through hole 10320.25mm≤(D can be met1-
D2)/2≤3mm。
Additionally, the outer diameter D of body 1001With the minimum diameter D of through hole 10320.1≤D can also be met2/D1≤0.9。
Although label layer 104 shown in the accompanying drawings is generally concerned with the Central Symmetry of anti-dazzling screen 10, this area skill
Art personnel are not limited by lifted implementation method it should be understood that the set-up mode of label layer 104 can be diversified.
For example, label layer 104 may be configured as deviateing the belt-like form at the center of anti-dazzling screen 10.Again for example, label layer 104 may also be configured to appoint
Anticipate discontinuous belt-like form.The set-up mode of all recognition reactions that can realize label layer 104, should be included in the application
In claimed scope.
The application also provides a kind of Image lenses, and the Image lenses include anti-dazzling screen as described above.
Above description is only the preferred embodiment and the explanation to institute's application technology principle of the application.People in the art
Member is it should be appreciated that involved invention scope in the application, however it is not limited to the technology of the particular combination of above-mentioned technical characteristic
Scheme, while should also cover in the case where the inventive concept is not departed from, is carried out by above-mentioned technical characteristic or its equivalent feature
Other technical schemes for being combined and being formed.Such as features described above has similar work(with (but not limited to) disclosed herein
The technical scheme that the technical characteristic of energy is replaced mutually and formed.
