Problems solved by technology

However, before the assembled lens, mirror holder and filter are pasted on the circuit board, since the photosensitive chip is exposed to the air for a long time, it is easy to be polluted by dust. When the light passes through the lens and the filter and reaches the photosensitive chip , the image will have obvious errors, which will affect the quality of the image

Embodiment Construction

[0016] figure 1 A method for assembling a lens module provided by a preferred embodiment of the present invention is illustrated. According to different requirements, the sequence of steps in the method for assembling the lens module can be changed, and some steps can be omitted or combined. Please also refer to Figure 2 to Figure 4 , the assembly method of the lens module includes the following steps:

[0017] Step S1 : providing a circuit board 10 , a photosensitive chip 20 , a filter 30 and a hollow mounting bracket 40 .

[0018] In this embodiment, the circuit board 10 is a printed circuit board, such as a flexible board, a rigid board, or a rigid-flex board. A connector 11 is mounted on one surface of the circuit board 10, and a connector 11 is mounted on the other surface. A plurality of electronic components 12 .

[0019] In this embodiment, the mounting bracket 40 is substantially square, which includes four first sides 41 connected end to end. The four first sid...

Abstract

Disclosed is an assembling method of a lens module. The assembling method comprises the following steps that a circuit board, a photosensitive chip, a light filter and a hollow mounting bracket are provided; the photosensitive chip is fixed on the circuit board; the light filter is fixed on one surface of the mounting bracket, and the other surface of the mounting bracket with the light filter isfixed on the circuit board, so that the light filter, the mounting bracket and the circuit board form a closed accommodating space so as to accommodate the photosensitive chip therein; a lens and a lens holder are provided, and the lens is installed in the lens holder to form a lens unit; and the lens holder of the lens unit is fixed on the circuit board, so that the lens is opposite to the photosensitive chip so as to obtain the lens module.

Description

technical field [0001] The invention relates to the field of photography, in particular to a lens module and an assembly method of the lens module. Background technique [0002] Conventional medium and large size lens modules generally include a lens, a lens holder, a filter, a photosensitive chip and a circuit board. When assembling, generally fix the lens and the lens base first, and then paste the filter on the lens base. After the photosensitive chip is pasted on the circuit board, paste the assembled lens, lens base and filter to the circuit board together. on the board so that the lens faces the photosensitive chip. However, before the assembled lens, mirror holder and filter are pasted on the circuit board, since the photosensitive chip is exposed to the air for a long time, it is easy to be polluted by dust. When the light passes through the lens and the filter and reaches the photosensitive chip , the image will have obvious delays, which will affect the quality o...
