Camera module and assembly method thereof

Abstract

The invention provides a camera module and an assembly method thereof. The camera module comprises a voice coil motor and a lens set, the voice coil motor comprises a motor carrier, the lens group isarranged in the motor carrier, the lens group comprises a lens cone and a lens, a gap is reserved between the motor carrier and the lens cone, a first groove is formed in an inner wall of the motor carrier by depressing toward the interior of the main body and / or a second groove is formed in an outer wall of the lens cone by depressing toward the interior of the main body, the first groove and / orthe second groove communicates with the gap between the motor carrier and the lens cone, and the first groove and / or the second groove and the gap between the motor carrier and the lens cone is filled with viscose to fix the motor carrier and the lens cone. According to the camera module and the assembly method thereof provided by the invention, due to the setting of the first and second grooves,the contact areas of the motor carrier and the lens cone with the viscose can be increased, thus improving the combination reliability, even if the viscose cracks, the viscose filled in the first groove and the second groove also limits the motor carrier and the lens cone, thereby ensuring that the motor carrier and the lens cone are not separated.

Description

technical field [0001] The invention relates to the technical field of cameras, in particular to a camera module and an assembly method thereof. Background technique [0002] Along with the progress of science and technology, the application of camera is more and more extensive, at present, except camera, mobile phone, computer and other electronic products are all equipped with camera, to facilitate people to take pictures anytime and anywhere, to bring convenience and fun to people's life. Moreover, people's requirements for the performance of the camera are getting higher and higher, requiring the camera to have the function of realizing automatic focus, and also requiring it to have functions such as high pixel and anti-shake. [0003] In order to realize the automatic focus function of the camera, it is necessary to set up a voice coil motor to drive the lens group to move up and down to achieve zooming. At present, the combination of the lens group and the voice coil ...

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
