The invention discloses a camera module, which includes a circuit board, an image sensing chip, a lens and a voice coil motor. The image sensing chip is electrically connected to the circuit board, and the image sensing chip has a first optical axis. The lens has a second optical axis. The voice coil motor is used to drive the lens to move, the voice coil motor is electrically connected to the circuit board, and the voice coil motor includes a first coil and a second coil. The first coil moves the lens along the direction of the second optical axis by being energized. The second coil moves the lens in a plane perpendicular to the second optical axis by being energized. The first coil and the second coil are used to ensure that the second optical axis is aligned with the first optical axis. The invention also discloses a camera module assembly method. In this way, during the assembly process of the camera module, by energizing the first coil and the second coil at the same time, the lens is prevented from shaking back and forth, thereby ensuring that the second optical axis of the lens is aligned with the first optical axis of the image sensor chip. axis, improving production yield.
Description
technical field [0001] The invention relates to the field of camera technology, in particular to a camera module and an assembly method of the camera module. Background technique [0002] After the lens and the voice coil motor are assembled, the circuit board and the voice coil motor are directly bonded to complete the assembly of the camera module. However, in the current assembly process, due to the special structure of the voice coil motor, the lens inside the voice coil motor will shake back and forth, left and right when the power is off, and it is difficult to ensure that the lens is in a horizontal or central position during the assembly process, resulting in The production yield of the camera module is reduced. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention needs to provide a camera module. [0004] The present invention also needs to provi...
