Problems solved by technology

Among them, the voice coil motor and the bearing seat are usually mainly bonded by glue, but due to the material of the glue and the bonding area, the bonding strength is not enough, which often leads to the separation of the voice coil motor and the bearing seat. Generally, in order to reduce the size of the product, the height of the lens module is usually chosen to be lowered. At the same time, in order to prevent glue overflow, the glue overflow storage space is usually involved. There is a storage space for glue overflow on the edge, which will further reduce the glue contact area between the voice coil motor and the bearing seat, thereby reducing the safety factor of glue bonding strength, and making the voice coil motor and the bearing seat easy to separate
In addition, in order to improve the bonding strength between the voice coil motor and the bearing seat, it is necessary to use colloid with high bonding strength and high bonding safety factor, which will increase the cost

Abstract

A lens module, comprising a voice coil motor, a bearing seat, and colloid connecting the voice coil motor and the bearing seat, grooves are arranged on the side walls of the bearing seat, and the grooves are filled with the colloid, The colloid has a cube shape with a protruding part, and the protruding part is engaged with the bearing seat. The invention also provides an electronic device using the lens module.

Description

technical field [0001] The invention relates to the field of electronics and optical devices, in particular to a lens module and an electronic device. Background technique [0002] Most lens modules are composed of six parts: lens, glass filter, carrier, voice coil motor, photosensitive chip and circuit board. Among them, the voice coil motor and the bearing seat are usually mainly bonded by glue, but due to the material of the glue and the bonding area, the bonding strength is not enough, which often leads to the separation of the voice coil motor and the bearing seat. Generally, in order to reduce the size of the product, the height of the lens module is usually chosen to be lowered. At the same time, in order to prevent glue overflow, the glue overflow storage space is usually involved. There is a storage space for glue overflow on the edge, which will further reduce the glue contact area between the voice coil motor and the bearing seat, thereby reducing the safety fact...
