Camera module group

Abstract

Disclosed in the invention is a camera module group comprising a lens barrel, a lens seat, a lens piece group, and a light filter. The lens seat has an upper surface, a lower surface, and an inner cavity penetrating the upper surface and the lower surface. One part of or the whole lens barrel is accommodated into the lens seat; and the lens barrel and the lens seat form an integrated structure. The lens piece group is accommodated into the lens barrel. The lens seat includes a boss that is arranged at the inner wall of the lens seat in a protruding mode and is located between the lens barrel and the lower surface. The light filter is fixed at the bottom of the boss; and an air discharge duct is formed in the bottom of the boss. An exhaust vent is formed in the lens seat and extends to the upper surface of the lens seat from the bottom of the boss. The air discharge duct and the exhaust vent are communicated with each other; and with the air discharge duct and the exhaust vent, the inner cavity and the external space of the lens seat are communicated. Therefore, gas caused by heating solidification glue can be exhausted outside of the camera module group timely, thereby avoiding the influence on the smoothness among all electronic elements of the camera module group. Besides, the lens barrel and the lens are in an integrated mode, so that a phenomenon that the imaging quality is affected due to chippings generated during the assembling process can be prevented.

Description

technical field [0001] The invention relates to the field of optical photography, in particular to a camera module. Background technique [0002] Electronic products such as mobile devices, computers, and electronic watches usually have a camera module, and the module usually includes a lens barrel, a lens mount, a lens set, a filter, an image sensor, and a circuit board. When assembling in the traditional process, first the filter is glued into the lens holder by glue, then the lens holder is attached to the circuit board by glue, and then the lens barrel containing the lens group and the lens holder are snapped together through threads. In this way, when the lens barrel and the lens base are fitted through the screw teeth, the falling debris will contaminate the filter, thereby affecting the image quality. And when matching the lens barrel containing the lens group with the lens base, it is necessary to carry out the focusing process on the machine, that is, to rotate the...

AI Technical Summary

Problems solved by technology

When assembling in the traditional process, first the filter is glued into the lens holder by glue, then the lens holder is attached to the circuit board by glue, and then the lens barrel containing the lens group and the lens holder are snapped together through threads. In this way, when the lens barrel and the lens base are fitted through the screw teeth, the falling debris will contaminate the filter, thus affecting the image quality

And when matching the lens barrel containing the lens group with the lens base, it is necessary to carry out the focusing process on the machine, that is, to rotate the lens barrel to the predetermined position where the shooting image is clear, and then click on the thread where the lens barrel and the lens base match. Glue fixation, so time-consuming focusing and low efficiency

Because the lens base and the circuit board are bonded by glue, the glue used is heated and cured, which is easy to generate gas. In the traditional process, the above-mentioned gas is discharged through the thread gap between the lens barrel and the lens base. In fact, it is difficult to remove the gas in time. The gas is discharged out of the camera module, causing the air pressure inside and outside the camera module to be unbalanced, which can easily affect the flatness between the electronic components of the camera module, thereby affecting the imaging quality of the camera module
