Problems solved by technology
In order to securely fix the second lens in the lens barrel, glue is usually dispensed at multiple places on the surface of the spacer ring. Therefore, it is necessary to relatively rotate the lens barrel and the glue injector to dispense glue at multiple places, resulting in the digital camera lens The module assembly process is time-consuming
In addition, the dispensing amount of the glue injector is not easy to control. On the one hand, when the second lens is assembled, it is easy to overflow the glue, which affects the imaging quality of the entire lens; Unevenness causes stress on the joint between the second lens, lens barrel and spacer ring. Under long-term use, the second lens is easy to fall off from the lens barrel and spacer ring, making the camera lens module unusable

Embodiment Construction
[0023] A preferred embodiment of the spacer ring for a camera lens of the present invention is described by taking its application to a camera lens 10 as an example.
[0024] see figure 1 As shown, the camera lens 10 includes a lens barrel 11 , a first lens 12 , a second lens 13 and a spacer ring 20 . The protruding ring on the inner wall of the lens barrel 11 is provided with a stop ring 111 . The first lens 12 includes an optical part 121 for imaging and a holding part 123 for fixing the lens 12 . The structure of the second lens 13 is similar to that of the first lens 12 , including an optical part 131 and a holding part 133 .
[0025] Please also refer to figure 1 with figure 2 As shown, the spacer ring 20 is in the shape of a ring, its diameter is equivalent to that of the lens barrel 11 , and its thickness is set according to the optical requirements of the camera lens 10 . The spacer ring 20 has a top surface 201 and a bottom surface 203 opposite to the top surfac...

This invention relates to interval circellus used for camera lens, camera lens and its assembly method. A camera lens includes a body tube, many lenses, at least an interval circellus and mucilage. A stopping circellus is on inner prominence of body tube. Many lenses are in body tube, and a lens links with stopping circellus of body tube. This interval circellus is installed in body tube, every interval circellus is installed between two lenses. This interval includes an apical side and a hole. A toroid slot is on apical side of the interval circellus. The hole of this interval circellus and toroid slot are at the same axis, and diameter of hole is smaller than toroid slot diameter. This hole is on the optical path of lenses. The mucilage is applied on the outside of toroid slot of apical side of interval circellus, adjunce inner wall of body tube. This lens links with apical side of close interval circellus and inner wall of body tube by mucilage.
Description
【Technical field】 [0001] The present invention relates to an optical element for a lens, a camera lens and an assembly method thereof, in particular to a spacer ring for a camera lens, a camera lens and an assembly method thereof. 【Background technique】 [0002] With the continuous development of technology, portable electronic devices, such as mobile phones, are widely used and tend to be light, beautiful and multi-functional. The camera function is an additional function of the popular mobile phones in recent years. A digital camera module used in a mobile phone must not only meet the requirements of thinness, lightness and compactness, but also have better photographic performance. The digital camera lens module assembly method is a major factor that determines the photographic performance, especially in the digital camera lens module assembly process, the assembly process must consider the convenience of mass production and cost reduction, and at the same time the assemb...
