Description
技术领域technical field
本发明涉及一种光学镜头领域，尤其涉及一种间隔环、包含该间隔环的光学镜头及包含该光学镜头的摄像模组。The invention relates to the field of optical lenses, in particular to a spacer ring, an optical lens comprising the spacer ring and a camera module comprising the optical lens.
背景技术Background technique
近几年来，随着科技的不断进步，带动手机平板计算机等搭载有成像装置的个人化电子产品及移动通讯产品的普及，连带带动小型化成像镜头的兴起，对优良成像品质的小型化成像镜头的需求也大幅攀升。传统的成像镜头普遍没有空间使用承靠件(间隔环)，只能通过两透镜直接进行承靠，但这样直接承靠使镜片失高大，离型风险大，且有组立应力集中透镜，影响成像品质。In recent years, with the continuous advancement of science and technology, the popularization of personal electronic products and mobile communication products equipped with imaging devices such as mobile phones and tablet computers has led to the rise of miniaturized imaging lenses. Miniaturized imaging lenses with excellent imaging quality demand has also increased significantly. Traditional imaging lenses generally do not have space to use a supporting member (spacer ring), and can only be directly supported by two lenses. However, such a direct bearing makes the lens lose its height, and the risk of separation is high, and there is a stress concentration on the assembled lens, which affects Image quality.

根据本发明的一个方案，间隔环避让光学镜头中的镜片，即间隔环与镜片上的凸台不相接触，相互避让，因此有效地减少了组立镜头时应力集中于透镜上的问题。同时，因为间隔环与镜片凸台不相接触，因此使得间隔环与镜片在组立镜头时的组装配合更加方便快捷，不需要过多考虑装配精度的问题，使得对间隔环和镜片的加工制造要求不会过高，节约了各项成本。此外，因为间隔环与镜片上的凸台不相接触，因此间隔环不设有伸入镜头内部的内径面，所以不会有挡光的问题出现，不会影响光学镜头的成像品质，使得组立后的光学镜头成像效果好。According to a solution of the present invention, the spacer ring avoids the lens in the optical lens, that is, the spacer ring and the boss on the lens do not touch each other, and avoid each other, thus effectively reducing the problem of stress concentration on the lens when the lens is assembled. At the same time, because the spacer ring is not in contact with the boss of the lens, the assembly of the spacer ring and the lens is more convenient and quick, and there is no need to consider the problem of assembly accuracy too much, so that the processing and manufacturing of the spacer ring and the lens The requirements will not be too high, saving various costs. In addition, because the spacer ring is not in contact with the boss on the lens, the spacer ring does not have an inner diameter surface protruding into the lens, so there will be no problem of light blocking, and it will not affect the imaging quality of the optical lens. The imaging effect of the optical lens after standing is good.
根据本发明的一个方案，设置有凸台的镜片，因为其具备0°-80°的凸台结构，因此使得镜片更容易从模具中脱离，使得加工制造后更容易脱模使用。According to one solution of the present invention, the lens provided with the boss, because it has a boss structure of 0°-80°, makes it easier for the lens to be released from the mold, making it easier to release the lens for use after processing.

图1示意性表示根据本发明的一种实施方式的光学镜头的局部剖视图。如图1所示，根据本发明的光学镜头包括镜筒4、安装在镜筒4中的透镜组2以及安装在镜筒4中的间隔环1。在本发明中，透镜组2至少包括两个镜片。如图1所示，在本实施方式中，透镜组2包括第一镜片201和第二镜片202。FIG. 1 schematically shows a partial cross-sectional view of an optical lens according to an embodiment of the present invention. As shown in FIG. 1 , the optical lens according to the present invention includes a lens barrel 4 , a lens group 2 installed in the lens barrel 4 , and a spacer ring 1 installed in the lens barrel 4 . In the present invention, the lens group 2 includes at least two lenses. As shown in FIG. 1 , in this embodiment, the lens group 2 includes a first lens 201 and a second lens 202 .
如图1所示，根据本发明的间隔环1支承在第一镜片201和第二镜片202之间。在本发明中，间隔环1是用于间隔光学镜头中的两个相邻的镜片的。如图1所示，间隔环1包括承靠承靠第一镜片201的第一表面101、承靠第二镜片202的第二表面102以及与镜筒内壁相互配合连接的第三表面103。特别地，根据本发明的间隔环1还包括一个远离第三表面103的第四表面104，第四表面是用于避让光学镜头中的镜片的，例如图1中第四表面104与第二镜片202上的凸台相互间隔设置，两者之间不接触。根据本发明的一种实施方式，第四表面104为锥形内表面，如图1所示，第四表面104的侧向截面为一条与光学镜头的光轴具有一定角度的斜线，其与第二镜片202上的凸台大致形状配合地设置，如此设置更容易避让光学镜头中带有凸台等结构的镜片。As shown in FIG. 1 , a spacer ring 1 according to the invention is supported between a first optic 201 and a second optic 202 . In the present invention, the spacer ring 1 is used to space two adjacent lenses in the optical lens. As shown in FIG. 1 , the spacer ring 1 includes a first surface 101 against the first lens 201 , a second surface 102 against the second lens 202 , and a third surface 103 mated with the inner wall of the lens barrel. In particular, the spacer ring 1 according to the present invention also includes a fourth surface 104 away from the third surface 103, the fourth surface is used to avoid the lens in the optical lens, for example, the fourth surface 104 and the second lens in Fig. 1 The bosses on the 202 are spaced apart from each other without contact. According to one embodiment of the present invention, the fourth surface 104 is a tapered inner surface. As shown in FIG. The protrusions on the second lens 202 are generally arranged in a form-fitting manner, so that it is easier to avoid lenses with structures such as protrusions in the optical lens.
在本发明中，由于间隔环1避让光学镜头中的镜片，即间隔环1与镜片上的凸台不相接触，相互避让，因此有效地减少了组立镜头时应力集中于透镜上的问题。同时，因为间隔环1与镜片凸台不相接触，因此使得间隔环1与镜片在组立镜头时的组装配合更加方便快捷，不需要过多考虑装配精度的问题，使得对间隔环1和镜片的加工制造要求不会过高，节约了各项成本。此外，因为间隔环1与镜片上的凸台不相接触，因此间隔环1不设有伸入镜头内部的内径面，所以不会有挡光的问题出现，不会影响光学镜头的成像品质，使得组立后的光学镜头成像效果好。In the present invention, since the spacer ring 1 avoids the lens in the optical lens, that is, the spacer ring 1 and the boss on the lens do not touch each other and avoid each other, so the problem of stress concentration on the lens when the lens is assembled is effectively reduced. At the same time, because the spacer ring 1 is not in contact with the boss of the lens, the assembly of the spacer ring 1 and the lens is more convenient and quick, and there is no need to consider the problem of assembly accuracy too much, so that the distance between the spacer ring 1 and the lens The processing and manufacturing requirements will not be too high, saving various costs. In addition, because the spacer ring 1 is not in contact with the boss on the lens, the spacer ring 1 is not provided with an inner diameter surface protruding into the inside of the lens, so there will be no problem of light blocking, and the imaging quality of the optical lens will not be affected. The imaging effect of the assembled optical lens is good.
如图1所示，第二镜片202靠近间隔环1的一侧的表面上设有凸台2021，具体地，凸台2021是设置在远离间隔环1的第三表面103并且与第四表面104间隔设置的，即凸台2021设置在靠近间隔环1的第四表面104的一侧。在本发明中，凸台2021与第四表面104之间相互间隔设置，这样凸台2021可以有效地避开间隔环1，即与间隔环1不相接触。As shown in Figure 1, a boss 2021 is provided on the surface of the second lens 202 close to the side of the spacer ring 1, specifically, the boss 2021 is arranged on the third surface 103 away from the spacer ring 1 and connected to the fourth surface 104 They are arranged at intervals, that is, the bosses 2021 are arranged on a side close to the fourth surface 104 of the spacer ring 1 . In the present invention, the boss 2021 and the fourth surface 104 are spaced apart from each other, so that the boss 2021 can effectively avoid the spacer ring 1 , that is, it is not in contact with the spacer ring 1 .
在本发明中，第一镜片201和第二镜片202上均可设置凸台2021，可以是单独一片镜片(即第一镜片201或者第二镜片202)设置凸台2021，也可以是两个镜片(即第一镜片201和第二镜片202)同时设置凸台2021。根据不同的设置情况，间隔环1上的第四表面104可以根据情况设置形状，当其中一片镜片设置凸台2021时，第四表面104可以设置成锥形内表面，如图1所示，只要锥形内表面的倾斜方向与凸台2021的倾斜方向相互配合即可。当两个镜片同时设置凸台2021时，第四表面104可以设置成没有倾斜角度的圆弧形表面，即圆柱形内表面，这样可以同时避让两个凸台2021。当然还可以设置成两个相对的、对称或者大致对称的圆锥形内表面，即双锥形内表面。此双锥形内表面的倾斜反向分别与两个凸台相互适配，此时从间隔环1的截面看，第四表面104是由一个三角形的两条边构成的。In the present invention, both the first lens 201 and the second lens 202 can be provided with the boss 2021, and the boss 2021 can be set on a single lens (that is, the first lens 201 or the second lens 202), or it can be two lenses. (that is, the first lens 201 and the second lens 202 ) are provided with a boss 2021 at the same time. According to different settings, the fourth surface 104 on the spacer ring 1 can be shaped according to the situation. When one of the lenses is provided with a boss 2021, the fourth surface 104 can be set as a tapered inner surface, as shown in Figure 1, as long as The inclination direction of the tapered inner surface and the inclination direction of the boss 2021 can cooperate with each other. When two lenses are provided with bosses 2021 at the same time, the fourth surface 104 can be set as an arc-shaped surface with no inclination angle, that is, a cylindrical inner surface, so that the two bosses 2021 can be avoided at the same time. Of course, it can also be set as two opposite, symmetrical or approximately symmetrical conical inner surfaces, that is, double-conical inner surfaces. The inclination of the double-cone inner surface fits with the two bosses respectively. At this time, viewed from the cross-section of the spacer ring 1, the fourth surface 104 is formed by two sides of a triangle.
如图1所示，根据本发明的一种实施方式，凸台2021具有与第四表面104相互间隔的第五表面2021a。第五表面2021a可以为锥形面，并且其沿着光学镜头的光轴方向具有0°-80°的倾斜角度，如图1中所示的β取值为0°-80°。根据本发明的设置有前述凸台2021的镜片，因为其具备0°-80°的凸台结构，因此使得镜片更容易从模具中脱离，使得加工制造后更容易脱模使用。As shown in FIG. 1 , according to an embodiment of the present invention, the boss 2021 has a fifth surface 2021 a spaced from the fourth surface 104 . The fifth surface 2021a may be a tapered surface, and it has an inclination angle of 0°-80° along the optical axis of the optical lens, and the value of β as shown in FIG. 1 is 0°-80°. According to the lens provided with the above-mentioned boss 2021 according to the present invention, because it has a boss structure of 0°-80°, the lens is easier to release from the mold, making it easier to release the lens for use after processing.
根据本发明的一种实施方式，凸台2021的轴向高度a和径向高度b均为0.05mm-0.5mm。如此设置尺寸可以有效地增加流道，减小镜头有效径内的应力，并且给间隔环1腾出安装空间。值得注意的是，流道为熔融塑料自射出机射嘴到模穴的必经信道。在本实施方式中，镜片增加凸台结构，流进有效径内的熔融塑料会先经过凸台结构，相当于增加了流道，减小了熔融塑料对有效径内的缓冲力。According to an embodiment of the present invention, both the axial height a and the radial height b of the boss 2021 are 0.05mm-0.5mm. Setting the size in this way can effectively increase the flow channel, reduce the stress in the effective diameter of the lens, and make room for the spacer ring 1 to install. It is worth noting that the runner is the necessary channel for the molten plastic to pass through from the nozzle of the injection machine to the mold cavity. In this embodiment, the lens adds a boss structure, and the molten plastic flowing into the effective diameter will first pass through the boss structure, which is equivalent to increasing the flow channel and reducing the buffering force of the molten plastic on the effective diameter.
根据本发明的一种实施方式，间隔环1的厚度c为0.2mm-0.5mm。如此设置尺寸可以分摊光学镜头中镜片的壁厚，这样有利于镜片的制造加工成型。同时，有利于组立光学镜头的稳定性，可以防止镜片被压裂。而且起到了稳定承靠镜片的作用。According to one embodiment of the present invention, the thickness c of the spacer ring 1 is 0.2mm-0.5mm. Setting the size in this way can share the wall thickness of the lens in the optical lens, which is beneficial to the manufacturing, processing and shaping of the lens. At the same time, it is beneficial to the stability of the assembled optical lens and can prevent the lens from being crushed. And it plays the role of stabilizing the lens.
图2示意性表示根据本发明的另一种实施方式的光学镜头的局部剖视图。如图2所示，此实施方式的光学镜头除了包括镜筒4、安装在镜筒4中的透镜组2以及安装在镜筒4中的间隔环1以外，还包括一个遮光片3。在本实施方式中，透镜组2同样至少包括第一镜片201和第二镜片202，遮光片3是设置在第一镜片201和间隔环1之间或者设置在第二镜片202和间隔环1中间。在设置遮光片3时，第一镜片201和第二镜片202中只有一个镜片设置有凸台2021，即与遮光片3相互承靠的镜片上不设有凸台。在本发明中，对遮光片3的设置可以视具体情况而定，在有必要遮挡杂散光时才设置遮光片3，光学成像质量达标时可以不设置遮光片3。在本实施方式中，遮光片3的厚度d为0.01mm-0.1mm，如此设置尺寸可以起到承靠镜片和间隔环1的作用，同时有效地遮挡杂散光。Fig. 2 schematically shows a partial cross-sectional view of an optical lens according to another embodiment of the present invention. As shown in FIG. 2 , the optical lens of this embodiment includes a lens barrel 4 , a lens group 2 installed in the lens barrel 4 , and a spacer ring 1 installed in the lens barrel 4 , and also includes a shading sheet 3 . In this embodiment, the lens group 2 also at least includes a first lens 201 and a second lens 202, and the shading sheet 3 is arranged between the first lens 201 and the spacer ring 1 or between the second lens 202 and the spacer ring 1 . When the light-shielding sheet 3 is installed, only one of the first lens 201 and the second lens 202 is provided with a boss 2021 , that is, the lens that bears against the light-shielding sheet 3 is not provided with a boss. In the present invention, the setting of the shading sheet 3 can be determined according to specific conditions, and the shading sheet 3 is only provided when it is necessary to shield stray light, and the shading sheet 3 may not be provided when the optical imaging quality is up to standard. In this embodiment, the thickness d of the light-shielding sheet 3 is 0.01mm-0.1mm, such a size can play the role of supporting the lens and the spacer ring 1 while effectively shielding stray light.
此外，根据本发明的上述间隔环1和光学镜头的设置，本发明还提供一种包括上述具备间隔环1的光学镜头的摄像模组。根据本发明的摄像模组包括镜座，用于支承上述光学镜头；底座，用于支承镜座；滤光片，支承在底座上，位于所述镜头的一侧；感光芯片，位于滤光片的一侧；电子元器件，位于感光芯片旁与感光芯片电连接；线路板，支承底座、感光芯片和电子元器件，并且与感光芯片和电子元器件电连接。In addition, according to the arrangement of the above-mentioned spacer ring 1 and the optical lens of the present invention, the present invention also provides a camera module including the above-mentioned optical lens provided with the spacer ring 1 . The camera module according to the present invention includes a mirror base for supporting the above-mentioned optical lens; a base for supporting the mirror base; an optical filter supported on the base and located on one side of the lens; a photosensitive chip located on the optical filter One side of the circuit board; electronic components, located next to the photosensitive chip and electrically connected to the photosensitive chip; circuit board, supporting the base, photosensitive chip and electronic components, and electrically connected to the photosensitive chip and electronic components.
根据本发明的上述设置，具有间隔环1的光学镜头以及摄像模组可以使得透镜组中镜片的离型更好，镜头或者摄像模组的组立稳定性更好，成像质量和效果有效地提升，并且解决了镜片上应力集中的问题。According to the above-mentioned arrangement of the present invention, the optical lens and the camera module with the spacer ring 1 can make the release of the lenses in the lens group better, the stability of the lens or the camera module is better, and the imaging quality and effect can be effectively improved. , and solve the problem of stress concentration on the lens.
传统的镜头即便是使用了承靠件，承靠件也是与镜片上的凸台配合接触连接，这样解决不了组立应力集中在透镜上的问题。同时，因为承靠件与凸台相互承靠接触使得组装配合更加困难，精度要求更高，不易制造加工。此外，因为承靠件与凸台的相互承靠接触，承靠件需要制造一个尺寸较小可与凸台相接触的内径面，此内径面伸入两个镜片之间的内侧，靠近光学镜头的光轴，由于承靠件具有伸入的内径面，因此会造成不必要的挡光，影响光学镜头的成像品质。Even if the traditional lens uses a support piece, the support piece is also matched and contacted with the boss on the lens, which cannot solve the problem of the concentration of assembly stress on the lens. At the same time, because the supporting member and the boss are in contact with each other, the assembly and cooperation are more difficult, the precision requirement is higher, and it is not easy to manufacture and process. In addition, because the supporting member and the boss are in contact with each other, the supporting member needs to manufacture a smaller inner diameter surface that can be in contact with the boss. This inner diameter surface extends into the inner side between the two lenses and is close to the optical lens. The optical axis of the optical axis, because the supporting member has an inner diameter surface protruding in, it will cause unnecessary light blocking and affect the imaging quality of the optical lens.
