Example Embodiment

[0019] The preparation method of the lens module of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] See figure 1 A lens module 100 prepared by the preparation method of the lens module according to the embodiment of the present invention includes an optical element 10 , a lens group 30 and a circuit board 50 . The optical element 10 includes an infrared cut filter portion 11 and a lens barrel portion 20 . The infrared cut filter portion 11 is located at one end of the lens barrel portion 20 and is integrally structured with the lens barrel portion 20 . The lens group 30 is disposed in the lens barrel portion 20 and located on one side of the infrared cut filter portion 11 . One end of the lens barrel portion 20 away from the infrared cut filter portion 11 is fixed to the circuit board 50 .

[0021] The infrared cut filter part 11 is mainly used for filtering the light in the infrared wavelength band enter...

Abstract

The invention discloses a method for preparing a lens module, which comprises the following steps: preparing an infrared cut filter; forming a shielding block for shielding part of the surface of the infrared cut filter on the infrared cut filter; forming light blocking layers on the infrared cut filter and the shielding block; forming electromagnetic shielding layers on the light blocking layers; grinding the electromagnetic shielding layers and the light blocking layers to expose the shielding blocks to the outside; removing the shielding blocks from the infrared cut filter to form an optical element which comprises an infrared cut filter part formed by the infrared cut filter and a lens barrel part formed by the light blocking layers and the electromagnetic shielding layers; mounting a lens group in the lens barrel part of the optical element and on one side of the infrared cut filter part; and encapsulating the lens barrel part of the optical element provided with the lens group on a circuit board to obtain the lens module. The yield of the lens module product prepared by the method is high.

Description

technical field [0001] The invention relates to a preparation method of a lens module. Background technique [0002] With the development of science and technology, portable devices, such as mobile phones, digital cameras and other electronic products with camera and video functions, are widely used, and tend to be thinner, lighter and smaller. The portability and miniaturization of portable devices put forward the requirement of miniaturization for the lens module combined with it. According to the current state of the art, each part of the lens module is prepared separately in the production chain, for example, the lens barrel, the lens group, and the infrared cut filter are prepared separately and then assembled. However, as the components are miniaturized, it becomes difficult to assemble the components and lowers the product yield. Contents of the invention [0003] In view of this, it is necessary to provide a method for preparing a lens module with low assembly di...
