Discharged to the camera module bonding apparatus for mobile phones to improve workability by semi-automating a series of work processes to move and fix the camera module fixed to the bonding part by a subsequent process. It is about.

In general, a digital camera module mounted on a PC camera, a digital camera, a mobile phone, a PDA, etc. is applied to an image sensor, which is essential for the storage and transmission of digital images, and an accompanying optical technology. In order to achieve the feedback of the digital camera module, the digital camera module is becoming more compact and lighter as the camera family equipped with the digital camera module is becoming more complex, multifunctional, and smaller.

In addition, in the trend of commercializing high resolution image sensors, the lens assembly of the camera module is also miniaturized due to the miniaturization and high precision of the corresponding lens. The image sensor described above is roughly classified into a charge coupled device (CCD) image sensor and a complementary metal oxide semiconductor (CMOS) image sensor.

For this reason, the lens assembly of the camera module is miniaturized to require the assembly of the lens or the lens group, and to be assembled at the correct position without disengaging the lens during assembly.

6 and 7, the lens module 3 is coupled to the aforementioned sensor module 9 to check the focused camera module 15 (see S100).

When the lens holder 8 of the sensor module 9 is seated on the seating groove 10 formed in the suction port 11, the sensor module 9 is detected by a proximity sensor (not shown) to prevent external vacuum. Since the vacuum pressure is formed in the suction port 15 through a hose connected to a pump (not shown) or a vacuum generator, the camera module 15 is fixed to the suction port 15 by vacuum suction (see S200).

At this time, since the suction hole 11 in which the above-described seating groove 10 is formed is mounted inclined within a range of 10 to 45 degrees with respect to the ground, the camera module 15 may be easily mounted to the seating groove 10.

The camera module 15 fixed to the above-described deodorizing port 17 may be detached from the deodorizing port 17 and moved to a subsequent process through a conveyor not shown. At this time, the working time can be reduced by minimizing the separation time of the camera module 15 from the deodorizing port 17 (see S600). That is, the deodorization port 17 is lowered toward the conveyor due to the driving of the first cylinder 26 along the first guide rail 25 (referred to as a kidney drive), and at the same time, the second guide rail 28 is moved along the second guide rail 28. In the case of driving the cylinder 29 (referring to the extension driving), the falling time of separating the camera module 15 from the take-out port 17 and then dropping it on the conveyor can be shortened.

After the vacuum of the deodorization port 17 is released to separate the camera module 15 from the deodorization port 17, the camera module 15 is moved to the subsequent process by dropping the conveyor (see S700).

As described above, when fixing the coupling portion of the lens module 3 and the sensor module 9 constituting the focused camera module 15 so as to be mounted on the camera mobile phone, the camera module 15 to the suction port 11 By automating the work process of detachably fixing, the work process of applying an adhesive such as a bond harmful to the human body to the coupling part of the camera module, and the work process of moving the bonded camera module to the subsequent process, Simplify the work to be done to reduce the worker fatigue, mass production of the camera module due to the improved work efficiency can lower the cost and manufacturing costs, thereby increasing the price competitiveness.

As described above, the camera module bonding apparatus for a mobile phone according to the present invention has the following advantages.

After fixing and applying adhesive to the coupling part of the sensor module and the lens module of the focused camera module, it is possible to mass produce by semi-automating the operation of moving the camera module to a subsequent process, thereby having a price competitiveness.

In addition, by simplifying the operator's work to fix the camera module consisting of small parts to reduce the fatigue to create a pleasant working environment, significantly reduce the number of workers and reduce the manufacturing cost.
