Description
本發明涉及一種光學鏡片組，尤其涉及一種互卡承靠式光學鏡片組。 The invention relates to an optical lens set, in particular to a mutual card-bearing optical lens set.
近年來，隨著多媒體技術的發展，鏡頭模組的應用範圍越來越廣泛，如應用到數碼相機、攝像機及帶有攝像功能的手機等電子產品中。 In recent years, with the development of multimedia technology, the application range of lens modules has become more and more extensive, such as in electronic products such as digital cameras, video cameras, and mobile phones with camera functions.
在人們對數碼相機、攝像機及手機追求小型化的同時，也希望拍攝物體的影像畫面清晰。物體的成像品質在一定程度上取決於鏡頭模組中的各個鏡片之間的光軸偏心量，而這很大程度取決於鏡片的組裝方式。 While people are pursuing miniaturization of digital cameras, camcorders, and mobile phones, they also want to have a clear image of the subject. The image quality of an object depends to some extent on the optical axis eccentricity between the individual lenses in the lens module, which depends to a large extent on the way the lens is assembled.
先前一種鏡片組裝方式藉由在相鄰鏡片相對的表面上設置傾角相同且相互配合的內斜面以及外斜面，使組裝鏡片時，內斜面完全抵靠在外斜面內，從而使得兩個鏡片互卡承靠，保證鏡片之間同軸固定。然而，受限於鏡片成型工藝，內斜面與外斜面通常無法精准成型、緊密配合。若外斜面做得過寬時，將降低了鏡片之間接合的穩定性，且鏡片之間的偏心量增加，成像品質劣化。因此，一般會適量縮窄外斜面。然而，當外斜面縮得過窄時，組裝過程中內斜面與外斜面過渡緊密配合產生的應力可能會導致鏡片變形，同樣會劣化鏡頭模組的成像品質。 In the prior lens assembly method, by providing the inner inclined surface and the outer inclined surface with the same inclination and mutual matching on the opposite surfaces of the adjacent lenses, when the lens is assembled, the inner inclined surface completely abuts against the outer inclined surface, so that the two lenses are mutually engaged. Rely on, ensure that the lens is coaxially fixed. However, due to the lens forming process, the inner bevel and the outer bevel are generally not precisely formed and closely matched. If the outer bevel is made too wide, the stability of the joint between the lenses is lowered, and the amount of eccentricity between the lenses is increased, and the image quality is deteriorated. Therefore, it is generally appropriate to narrow the outer bevel. However, when the outer bevel is narrowed too narrowly, the stress generated by the tight transition of the inner bevel and the outer bevel during assembly may cause deformation of the lens, which may also degrade the imaging quality of the lens module.
有鑒於此，有必要提供一種優化成像品質的互卡承靠式光學鏡片組。 In view of this, it is necessary to provide a mutual card-bearing optical lens set that optimizes image quality.
一種互卡承靠式光學鏡片組，其至少包括第一鏡片及第二鏡片，該第一鏡片及第二鏡片均分別包括光學部和圍繞該光學部的非光學部。該第二鏡片的非光學部朝向該第一鏡片的表面上形成有第一凸緣，該第一鏡片的非光學部朝向該第二鏡片的表面上設置有與該第一凸緣對應的第一彈性部，該第一彈性部用於與該第一凸緣相互套接。該第一凸緣的外徑不小於該第一彈性部的內徑或者該第一凸緣的內徑不大於該第一彈性部的外徑。 A mutual card-bearing optical lens set includes at least a first lens and a second lens, each of the first lens and the second lens respectively including an optical portion and a non-optical portion surrounding the optical portion. a non-optical portion of the second lens is formed with a first flange on a surface of the first lens, and a non-optical portion of the first lens is disposed on a surface of the second lens corresponding to the first flange An elastic portion for splicing with the first flange. The outer diameter of the first flange is not less than the inner diameter of the first elastic portion or the inner diameter of the first flange is not greater than the outer diameter of the first elastic portion.
本發明的互卡承靠式光學鏡片組藉由在第一鏡片上設置第一彈性部，以及在第二鏡片上設置對應的第一凸緣與第一彈性部套接，即使第一凸緣的外徑尺寸過大(第一凸緣在第一彈性部內)或內徑尺寸過小(第一凸緣在第一彈性部外)，第一彈性部均可產生彈性形變來匹配第一凸緣，以穩定連接第一鏡片與第二鏡片，且使得第一鏡片與第二鏡片同軸，提高成像品質。另外，第一彈性部產生彈性形變還可以減小第一凸緣及第一彈性部產生的應力，避免第一鏡片及第二鏡片因此變形，從而提高互卡承靠式光學鏡片組的穩定性以及成像品質。 The mutual card-bearing optical lens set of the present invention is sleeved with the first elastic portion by providing a first elastic portion on the first lens, and a corresponding first flange is disposed on the second lens, even if the first flange The outer diameter is too large (the first flange is in the first elastic portion) or the inner diameter is too small (the first flange is outside the first elastic portion), and the first elastic portion can be elastically deformed to match the first flange. The first lens and the second lens are stably connected, and the first lens is coaxial with the second lens to improve image quality. In addition, the elastic deformation of the first elastic portion can also reduce the stress generated by the first flange and the first elastic portion, thereby preventing the first lens and the second lens from being deformed, thereby improving the stability of the mutual card-bearing optical lens group. And image quality.

下面將結合附圖對本發明作一具體介紹。 The present invention will be specifically described below with reference to the accompanying drawings.
如圖1至圖4所示，本發明實施方式的互卡承靠式光學鏡片組100，其包括相鄰設置的第一鏡片10、第二鏡片20及貼合在第二鏡片20上與第一鏡片10相背的第三鏡片30。該第一鏡片10、第二鏡片20、第三鏡片30均分別包括光學部和圍繞光學部的非光學部。本實施方式中，第一鏡片10、第二鏡片20以及第三鏡片30均採用塑膠製成。 As shown in FIG. 1 to FIG. 4, the mutual card-bearing optical lens set 100 of the embodiment of the present invention includes a first lens 10, a second lens 20, and a second lens 20 disposed adjacent to each other. A third lens 30 opposite the lens 10. The first lens 10, the second lens 20, and the third lens 30 each include an optical portion and a non-optical portion surrounding the optical portion. In this embodiment, the first lens 10, the second lens 20, and the third lens 30 are all made of plastic.
第一鏡片10的非光學部上設置有第一彈性部12，第一彈性部12從第一鏡片10的非光學部表面上朝第二鏡片20延伸。具體的，第一彈性部12包括多個環繞第一鏡片10的光學部設置的圓弧狀的第一凸台121。每兩個相鄰的第一凸台121之間形成有第一缺口123。當第一彈性部12受到徑向力時，每個第一凸台121能夠沿第一鏡片10的徑向發生彈性形變。本實施方式中，該第一凸台121以及第一缺口123的數量均為三個。第一彈性部12可與該第一鏡片10的光學部相連接，也可間隔設置。本實施方式中，第一彈性部12與第一鏡片10的光學部的外邊緣之間形成有第一間隔槽125。第一間隔槽125 使得第一彈性部12的徑向厚度減少。如此，在相同的作用力下，第一彈性部12可以發生更大的彈性形變。第一彈性部12靠近第一鏡片10光學部的第一內表面126為圓周斜面，該圓周斜面從第一鏡片10的表面沿徑向向外傾斜。本實施方式中，該第一彈性部12的材料為塑膠。 The non-optical portion of the first lens 10 is provided with a first elastic portion 12 that extends from the non-optical portion surface of the first lens 10 toward the second lens 20. Specifically, the first elastic portion 12 includes a plurality of arc-shaped first bosses 121 disposed around the optical portion of the first lens 10. A first notch 123 is formed between each two adjacent first bosses 121. When the first elastic portion 12 is subjected to a radial force, each of the first bosses 121 can be elastically deformed in the radial direction of the first lens 10. In the present embodiment, the number of the first boss 121 and the first notch 123 is three. The first elastic portion 12 may be connected to the optical portion of the first lens 10 or may be spaced apart. In the present embodiment, the first spacing portion 125 is formed between the first elastic portion 12 and the outer edge of the optical portion of the first lens 10. First spacing slot 125 The radial thickness of the first elastic portion 12 is reduced. Thus, under the same force, the first elastic portion 12 can undergo greater elastic deformation. The first inner surface 126 of the first elastic portion 12 adjacent to the optical portion of the first lens 10 is a circumferential bevel which is inclined radially outward from the surface of the first lens 10. In this embodiment, the material of the first elastic portion 12 is plastic.
第二鏡片20的非光學部表面上朝向第一鏡片10延伸有環狀的第一凸緣22。第一凸緣22的外表面也為圓周斜面，該圓周斜面從第二鏡片20的表面沿徑向向內傾斜，並等於或略小於第一彈性部12的第一內表面126的對應尺寸。如此，將第一彈性部12套接於第一凸緣22時，第一內表面126將緊密貼合在第一凸緣22的外表面，以固定第二鏡片20在第一鏡片10上。第二鏡片20朝向第三鏡片30的非光學部表面上形成有一環狀的第二凸緣24。該第二凸緣24的第二內表面241為一圓周斜面，該第二內表面241從第二鏡片20的表面沿徑向向外傾斜。 An annular first flange 22 extends toward the first lens 10 on the non-optical portion surface of the second lens 20. The outer surface of the first flange 22 is also a circumferential bevel that slopes radially inward from the surface of the second lens 20 and is equal to or slightly smaller than the corresponding dimension of the first inner surface 126 of the first resilient portion 12. As such, when the first elastic portion 12 is sleeved on the first flange 22, the first inner surface 126 will closely fit the outer surface of the first flange 22 to fix the second lens 20 on the first lens 10. The second lens 20 is formed with an annular second flange 24 on the surface of the non-optical portion of the third lens 30. The second inner surface 241 of the second flange 24 is a circumferential bevel which is inclined radially outward from the surface of the second lens 20.
第三鏡片30面向第二鏡片20的非光學部上形成有一個環繞第三鏡片30光學部的第二彈性部32。該第二彈性部32的外徑大致等於該第二凸緣24的內徑，該第二彈性部32收容在該第二凸緣24內。本實施方式中，該第二彈性部32的外徑還大於第一彈性部12的外徑。具體的，該第二彈性部32包括多個環繞該第三鏡片30光學部設置的圓弧狀的第二凸台321。每兩個相鄰的第二凸台321之間形成有一第二缺口323，當第二彈性部32受到徑向力時，每個第二凸台321能夠沿第三鏡片30的徑向發生彈性形變。本實施方式中，該第二凸台321以及第二缺口323的數量均為三個。第二彈性部32與該第三鏡片30的光學部外緣之間形成有一第二間隔槽34，如此，在相同的作用力下，第二彈性部32可以發生更大的彈性形變。第二彈性部32的外表面也為圓周斜面，其能夠與該第二凸緣24的第二內表面241相互貼合。本實施方式中，該第二彈性部32的材料為塑膠。 A second elastic portion 32 surrounding the optical portion of the third lens 30 is formed on the non-optical portion of the third lens 30 facing the second lens 20. The outer diameter of the second elastic portion 32 is substantially equal to the inner diameter of the second flange 24, and the second elastic portion 32 is received in the second flange 24. In the present embodiment, the outer diameter of the second elastic portion 32 is also larger than the outer diameter of the first elastic portion 12. Specifically, the second elastic portion 32 includes a plurality of second protrusions 321 arranged in an arc shape surrounding the optical portion of the third lens 30. A second notch 323 is formed between each two adjacent second bosses 321 . When the second elastic portion 32 receives a radial force, each of the second bosses 321 can be elasticized in the radial direction of the third lens 30. deformation. In the present embodiment, the number of the second bosses 321 and the second notches 323 is three. A second spacing groove 34 is formed between the second elastic portion 32 and the outer edge of the optical portion of the third lens 30. Thus, under the same force, the second elastic portion 32 can undergo greater elastic deformation. The outer surface of the second elastic portion 32 is also a circumferential bevel which is capable of abutting against the second inner surface 241 of the second flange 24. In this embodiment, the material of the second elastic portion 32 is plastic.
另外，第一鏡片10和第二鏡片20之間，以及第二鏡片20和第三鏡片30之間分別設置有一間隔環40。間隔環40用以固定第一鏡片10和第二鏡片20之間以及第二鏡片20和第三鏡片30之間的間距，且避免鏡片間直接硬性磨擦。 In addition, a spacer ring 40 is disposed between the first lens 10 and the second lens 20, and between the second lens 20 and the third lens 30, respectively. The spacer ring 40 is used to fix the spacing between the first lens 10 and the second lens 20 and between the second lens 20 and the third lens 30, and to avoid direct hard friction between the lenses.
當組裝該光學鏡片組100時，將第二鏡片20上的第二凸緣24卡接在第三 鏡片30的第二彈性部32的外表面。此時，如果該第二凸緣24的內徑過小，則第二彈性部32發生彈性形變來調整第二彈性部32的尺寸，從而使第二鏡片20與第三鏡片30穩定接合且同軸。然後，將第一鏡片10的第一彈性部12套接在第二鏡片20的第一凸緣22外表面，此時，如果該第一凸緣22的外徑過大，第一彈性部12發生彈性形變，使得第一鏡片10能夠穩定固持在該第二鏡片20上，且與該第二鏡片20同軸設置。 When the optical lens set 100 is assembled, the second flange 24 on the second lens 20 is snapped into the third The outer surface of the second elastic portion 32 of the lens 30. At this time, if the inner diameter of the second flange 24 is too small, the second elastic portion 32 is elastically deformed to adjust the size of the second elastic portion 32, so that the second lens 20 and the third lens 30 are stably joined and coaxial. Then, the first elastic portion 12 of the first lens 10 is sleeved on the outer surface of the first flange 22 of the second lens 20. At this time, if the outer diameter of the first flange 22 is too large, the first elastic portion 12 occurs. The elastic deformation causes the first lens 10 to be stably held on the second lens 20 and disposed coaxially with the second lens 20 .
可以理解，互卡承靠式光學鏡片組100並不限於本實施方式，其可以包括更多的鏡片，鏡片之間採用第一鏡片10、第二鏡片20及第三鏡片30之間的組裝方式組合。當然，在另一實施方式中，互卡承靠式光學鏡片組100也可僅包括第一鏡片10及第二鏡片20，或者僅包括第二鏡片20及第三鏡片30。 It can be understood that the mutual card-bearing optical lens set 100 is not limited to the embodiment, and may include more lenses, and the assembly between the first lens 10, the second lens 20 and the third lens 30 is adopted between the lenses. combination. Of course, in another embodiment, the mutual card-bearing optical lens set 100 may also include only the first lens 10 and the second lens 20, or only the second lens 20 and the third lens 30.
該互卡承靠式光學鏡片組100藉由在第一鏡片10上設置第一彈性部12，以及在第二鏡片20上設置對應的第一凸緣22與第一彈性部12套接，即使第一凸緣22的外徑尺寸過大(第一凸緣22在第一彈性部12內)或內徑尺寸過小(第一凸緣22在第一彈性部12外)，第一彈性部12均可產生彈性形變來匹配第一凸緣22，以穩定連接第一鏡片10與第二鏡片20，且使得第一鏡片10與第二鏡片20同軸，提高成像品質。另外，第一彈性部12產生彈性形變還可以減小第一凸緣22及第一彈性部12產生的應力，避免第一鏡片10及第二鏡片20因此變形，從而提高互卡承靠式光學鏡片組100的穩定性以及成像品質。 The mutual card-bearing optical lens set 100 is sleeved with the first elastic portion 12 by providing a first elastic portion 12 on the first lens 10, and a corresponding first flange 22 is disposed on the second lens 20, even if The outer diameter of the first flange 22 is too large (the first flange 22 is in the first elastic portion 12) or the inner diameter is too small (the first flange 22 is outside the first elastic portion 12), and the first elastic portion 12 is Elastic deformation can be generated to match the first flange 22 to stably connect the first lens 10 and the second lens 20, and the first lens 10 is coaxial with the second lens 20 to improve image quality. In addition, the elastic deformation of the first elastic portion 12 can also reduce the stress generated by the first flange 22 and the first elastic portion 12, thereby preventing the first lens 10 and the second lens 20 from being deformed, thereby improving the mutual card-bearing optics. The stability of the lens set 100 and the image quality.
