Embodiment
Below in conjunction with accompanying drawing, the eyeglass and the manufacture method thereof of the technical program is described in further detail.
See also Fig. 1, the eyeglass 10 that the technical program first embodiment provides comprises eyeglass body 110 and occulter 120.This eyeglass body 110 and occulter 120 are one-body molded.
Occulter 120 is formed at the first surface 113 of fixed part 112, is used for eyeglass body 110 and other optical elements are spaced apart and stop that light passes from the fixed part 112 of eyeglass body 110.Occulter 120 has a through hole 121.On the optical axis that is centered close to eyeglass body 110 60 of through hole 121, and the diameter basically identical of its diameter and optic 111, thereby the imaging light that penetrates this optic 111 can pass this through hole 121.In the present embodiment, occulter 120 comprises matrix 122 and the photomask 123 that is connected.Described matrix 122 has relative the 124 and the 4th surface 125, the 3rd surface, wherein, described the 3rd surface 124 is positioned at the side of matrix 122 near the first surface 113 of fixed part 112, and described the 4th surface 125 is positioned at the side of matrix 122 away from the first surface 113 of fixed part 112.The fusing point of the material of matrix 122 should be higher than 300 ℃, for example can or comprise the alloy of above-mentioned metal for metals such as aluminium, iron, copper, manganese, chromium, also can be glass cloth or titanium dioxide silicon cloth etc.Photomask 123 is used for shading, and its material can be the various black inks that comprise carbon black (Carbon black).Photomask 123 can be formed at matrix 122 by modes such as coating, plated films.In the present embodiment, photomask 123 is positioned at described the 4th surface 125, that is, photomask 123 is positioned at the side of occulter 120 away from the fixed part 112 of eyeglass body 110.Certainly, photomask 123 also can be positioned at described the 3rd surface 124, that is, and and between matrix 122 and eyeglass body 110.
See also Fig. 1 and Fig. 2, the manufacture method of the eyeglass 10 of the technical program can may further comprise the steps:
At first, an aforesaid occulter 120 and ejection shaping die 20 are provided, described ejection shaping die 20 has containing cavity 24 and the forming cavity 25 that is connected, and described containing cavity 24 is corresponding with described occulter 120, and described forming cavity 25 is corresponding with eyeglass body 110.
Particularly, mould 20 comprises first die 21, second die 22 and an injecting unit 23.First die 21 has a containing cavity 24, the second dies 22 and first die 21 constitutes the forming cavity 25 that is connected with described containing cavity 24 jointly.
Secondly, described occulter 120 is arranged at containing cavity 24.
Particularly, can adopt mechanical arm that occulter 120 is inserted in the containing cavity 24.Be appreciated that in the present embodiment that for the photomask 123 that makes occulter 120 is positioned at the side of occulter 120 away from eyeglass body 110, after occulter 120 was inserted containing cavity 24, photomask 123 was positioned at the side of containing cavity 24 away from forming cavity 25.
Once more, injected plastics material is injected into forming cavity 25 with formation eyeglass body 110, thereby obtains comprising the eyeglass 10 of integrated eyeglass body 110 and occulter 120.
Injected plastics material can adopt translucent resin.For example, can be acrylic resins such as polymethylmethacrylate, propyl group such as poly-diallyl carbonic acid binaryglycol ester, polycarbonate are resin.
Closed first die 21 and second die 22 are injected into die cavity 25 and cooling with molded lenses body 110 with the injected plastics material of molten condition, thereby obtain the eyeglass 10 that eyeglass body 110 and occulter 120 are combined as a whole.Treat that first die 21 is separated in eyeglass 10 cooling backs and second die 22 can take out finished product.
See also Fig. 1 and Fig. 3, the camera lens module 100 that the technical program first embodiment provides comprises a lens barrel 101 and is arranged on eyeglass 10, second eyeglass 102, occulter 103, cutoff filter 104 in the lens barrel 101.Because the eyeglass 10 of camera lens module 100 comprises occulter 120, so camera lens module 100 does not need to adopt other anti-dazzling screen, thereby can reduce the overall height of camera lens module 100, improve the image quality and the production efficiency of camera lens module 100.
See also Fig. 4, eyeglass 30 that the technical program second embodiment provides and the eyeglass 10 of first embodiment are basic identical, its difference is, occulter 320 integral body in the present embodiment are made by lighttight material, for example, make by the glass cloth of iron, manganese, chromium, ferroalloy, manganese alloy, evanohm, black or the materials such as titanium dioxide silicon cloth of black.
See also Fig. 5, eyeglass 40 that the technical program the 3rd embodiment provides and the eyeglass 10 of first embodiment are basic identical, its difference is, described occulter 420 is formed at the second surface 414 of fixed part 412, the 3rd surface 424 of occulter 420 contacts with the second surface 414 of fixed part 412, and photomask 423 is positioned at and the 3rd surperficial 424 relative described the 4th surface 425.That is, photomask 423 is positioned at the side of occulter 420 away from fixed part 412.
The technical program adopt in-molded technology (In Mold Decoration, IMD) that eyeglass body and occulter is one-body molded, adopt the camera lens module of above-mentioned eyeglass not need to adopt other anti-dazzling screen.And this occulter can play the effect of this eyeglass body of interval and other optical element again, thus need not other spaced ring, thus reduce the overall height of camera lens module, improve the packaging efficiency and the image quality of camera lens module.
Be understandable that those skilled in the art also can do other variation in the technical program spirit, certainly, the variation that these are done according to the technical program spirit all should be included within the technical program scope required for protection.
