Abstract

The invention provides an optical lens group, a molding method thereof, and a corresponding molding device. The optical lens group includes a first lens and a second lens. Both the first lens and the second lens include a mounting part and an optical part. A cavity is opened in the middle of the mounting part of the first lens and the second lens. The mounting part of the second lens includes a cylinder, and the cylinder of the second lens is locked in the cavity of the first lens. The cavity of the second lens includes a bottom wall, the optical part of the second lens includes a convex body and a groove, the shape of the groove corresponds to the shape of the convex body, and the groove is opened on the bottom wall And located on the convex body.

Description

【Technical field】 [0001] The invention relates to an optical lens group, a molding method thereof and a corresponding molding device. 【Background technique】 [0002] With the development of multimedia technology, digital cameras and video cameras are becoming more and more popular among consumers. While people are pursuing miniaturization of digital cameras and video cameras, they also put forward higher requirements for the imaging quality of the objects they shoot. The image picture of the object is clear, and the imaging quality of the object depends to a large extent on the pros and cons of each optical component in the digital camera. [0003] A set of lenses is arranged in the existing digital camera lens module, the set of lenses includes at least a first lens and a second lens, the first lens and the second lens are spaced apart, and the first lens and the second lens each include an optical part, the two optical parts focus the light on the image sensing element. ...
