Camera module and assembly method thereof

Abstract

A camera module and its assembly method, the camera module includes a voice coil motor and a lens group, the voice coil motor includes a motor carrier, the lens group is arranged in the motor carrier, the lens group includes a lens barrel and a lens, the motor carrier and the lens barrel There is a gap between them, the inner wall of the motor carrier is recessed into the body with a first groove and / or the outer wall of the lens barrel is recessed into the body with a second groove, the first groove and / or the second groove The groove communicates with the gap between the motor carrier and the lens barrel, and glue is filled in the first groove and / or the second groove and the gap between the motor carrier and the lens barrel to fix the motor carrier and the lens barrel. In the camera module and its assembly method provided by the present invention, due to the setting of the first and second grooves, the contact area between the motor carrier, the lens barrel and the adhesive can be increased, and the bonding reliability can be improved. Even if the adhesive cracks, it can be filled in the The glue in the first and second grooves will also limit the motor carrier and the lens barrel to ensure that the motor carrier and the lens barrel will not be separated.

Description

Technical field [0001] The present invention relates to the field of camera, and more particularly to a pixel module and a assembly method thereof. Background technique [0002] With the advancement of science and technology, the application of the camera is increasing. At present, in addition to the camera, mobile phone, computer and other electronic products are equipped with a camera to facilitate people to take pictures anytime, anywhere, bring convenience and fun to people's lives. Moreover, people's performance requirements for the camera are also increasing, requiring the camera to achieve automatic focus function, as well as high-pixel and anti-shakes. [0003] To achieve the automatic focus function of the camera, you need to set the voice coil motor to drive the lens group to move up and down to achieve zoom. At present, the combination of the lens group and the voice coil motor can be combined with the outer wall of the inner wall of the voice coil motor and the outer ...

AI Technical Summary

Problems solved by technology

At present, the combination of the lens group and the voice coil motor can be done by dispensing glue to combine the inner wall of the voice coil motor and the outer wall of the lens group. Since the bonding surface of the lens group and the bonding surface of the voice coil motor are relatively flat, When this combination method is used for the reliability drop test, there will be a risk of rubber cracking or even the lens group falling off, making the combination of the lens group and the voice coil motor weak, which poses a great threat to the camera function of the mobile phone
