Description
自定位自遮光式镜片 技术领域 Self-positioning self-shielding lens

随着电子产品多功能化的发展， 镜头模组在手机、 笔记本电脑、 数码相机、 个人数字助理等消费性电子产品中得到广泛应用。人们在 追求多功能花的同时， 也希望电子产品具有优良的影像效果， 即， 需 要镜头模组具有高质量的成像品质。 With the development of multi-functional electronic products, lens modules are widely used in consumer electronic products such as mobile phones, notebook computers, digital cameras, and personal digital assistants. While pursuing multi-functional flowers, people also hope that electronic products have excellent image effects, that is, lens modules are required to have high-quality imaging quality.
现有技术的一种镜头模组包括一个镜筒 221, 及设置在镜筒 221 内的一第一镜片 222、 间隔环 223、 第二镜片 224等。 所述镜头模组 内具有的多个光学元件通常沿镜筒 221轴线方向装设，以实现设计光 学性能， 达到预定成像品质。 组装时， 通常是采用将数个光学元件依 次装置于镜筒中。 由于镜片 222的外径与镜筒内径相当，镜片 222侧 面与镜筒 221内壁紧配合，故在组装时，镜片 222从镜筒上方装入镜 筒底部的整个过程都存在由于摩擦导致组装不易的困难，并且由于摩 擦，镜片 222很容易发生歪斜，从而影响整个镜头模组的组装效率及 成像品质， 造成镜头模组成为不良品。 如此不但降低了镜头模组的组 装良率， 而且大幅度增加了镜头模组的制造成本。 A lens module of the prior art includes a lens barrel 221, and a first lens 222, a spacer ring 223, a second lens 224, and the like disposed in the lens barrel 221. A plurality of optical components in the lens module are generally mounted along the axis of the lens barrel 221 to achieve design optical performance to achieve a predetermined imaging quality. When assembling, it is common to use a plurality of optical components to be sequentially mounted in the lens barrel. Since the outer diameter of the lens 222 is equivalent to the inner diameter of the lens barrel, and the side surface of the lens 222 is tightly fitted to the inner wall of the lens barrel 221, the assembly process of the lens 222 from the top of the lens barrel to the bottom of the lens barrel during assembly is difficult due to friction. Difficult, and due to friction, the lens 222 is prone to skew, which affects the assembly efficiency and image quality of the entire lens module, resulting in the lens module becoming a defective product. This not only reduces the assembly yield of the lens module, but also greatly increases the manufacturing cost of the lens module.
另外， 需要增加间隔环 223来调整两个镜片之间的距离， 增加了 材料和工序， 增加生产成本。 In addition, spacer ring 223 is required to adjust the distance between the two lenses, adding materials and processes, and increasing production costs.
