Description

Assembling apparatus of camera module

The present invention relates to an assembling apparatus for a camera module, and more particularly to an assembling apparatus for a camera module for a digital camera capable of adjusting focus at the same time as assembly.

Recently, a camera module has been developed for a digital camera that generates a predetermined image file by converting information about an image obtained through an optical system such as a lens into a digital signal. In particular, the digital camera module 10 mounted in a portable telephone or the like uses a micro lens module 11, as shown in FIG. 1, and the lens module 11 includes a CMOS in which a predetermined electronic circuit is mounted. Module, that is, attached to the sensor module 12 is used.

The camera module 10 is assembled to the sensor module 12 by the lens module 11 by a screw fastening method, and the assembly of the lens module 11 must be accompanied with this assembly.

FIG. 2 schematically illustrates an assembly process of a conventional camera module. As shown in the figure, the lens module 11 is mounted on the sensor module 12 in a state in which a separate assembly jig 21 supports the lens module 11. ) Is rotated, and at the same time, the focus of the lens module 11 is adjusted as an optical state projected on the light box 22.

However, such a conventional camera module assembly apparatus has a problem that manual assembly and adjustment as described above must be performed manually, and the process is very cumbersome, and in the case of a micro camera module, there is a problem that its adjustment is difficult.

In addition, there is also a limit when assembling the lens module and the sensor module as described above using a general screw fastening device. That is, a general screw fastening device uses the rotational force of a motor or a pneumatic device coaxially with the rotating part, wherein the light as shown in Figure 2 for the adjustment of the lens module due to the parts of the motor or pneumatic device It is impossible to secure the angle of view (23). Therefore, there is a limit that the assembly and adjustment of the lens module cannot be performed at the same time. Due to this limitation, the general screw fastening device is not used for the assembly of the lens module and the sensor module.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide an assembly apparatus of a camera module that can be adjusted at the same time as the assembly of the lens module and the sensor module.

Another object of the present invention is to provide an assembly apparatus of a camera module capable of automatically assembling and adjusting a lens module and a sensor module.
