First, in the pogo jig configuration according to the present embodiment, the main board 300 is provided at the top of which the opening 310 for directly receiving light into the main body of the camera module for inspection is directly formed. The main board 300 corresponds to a test PCB board corresponding to a main board installed outside of a camera module used in a product such as an actual camera phone.

That is, in the present invention, unlike the prior art, an opening 310 serving as a light receiving hole is directly formed in the main board 300 such as a PCB, and thus does not require a separate configuration other than the main board.

The guide jig 100 is fixed to the bottom surface of the main board 300 in which the opening 310 is directly formed. A pogo pin 110 is formed on the lower surface of the guide jig 100 to be electrically connected to the connector 31 of the camera module. That is, as described above, since the camera module applied to the present invention is an inspection device for the type in which the connector is formed on the upper part of the camera module, the pogo pin is electrically connected to the connector formed in the same upward direction as the mounting direction of the camera module. It is formed in the lower part of this guide jig (namely, downward direction of a main board).

The lower part of the guide jig 100 is provided with a cover jig 200 to be coupled to the guide jig 100 from the lower direction of the guide jig 100.

Since the camera module of the type described above is mounted on the top surface of the cover jig 200, when the camera module 30 is mounted on the cover jig 200, both the main body 32 and the connector 31 of the camera module 30 are all part of the cover jig 200.

As mentioned above, the inspection apparatus according to the embodiment of the present invention, since the connector 31 is for the camera module 30 is located on the upper surface of the module, the camera module 30 is mounted on the guide jig 200 If so, both the camera module body 32 including the lens unit and the connector 31 for external connection are directed upward.

As such, by the close coupling of the guide jig 100 and the cover jig 200, the pogo pin 110 and the upper part of the cover jig 200 are formed to be electrically connected to the main board 300 provided on the upper guide jig. The connector 31 mounted in the contact can be directly contacted without a separate substrate serving as a sub board.

That is, as schematically shown in FIG. 3 of the related art, the sub board 21 provided in the cover jig 20 has a first pogo pin 21a and a second pogo pin exposed downward. (pogo pin: 21b), and the first and second pogo pins (21a, 21b), as shown in Fig. 2 (b), the cover jig 20 moves downward to closely adhere to the guide jig (10). When combined, they are connected to the upper part of the connector 31 mounted on the guide jig 10 and the upper part of the main board 12 provided in the guide jig 10, so that these connectors 31 and the main board 12 are connected. ), It is required that the sub-board 21 for the electrical connection to the cover jig 20 is essentially installed. On the contrary, according to the embodiment of the present invention, as shown in FIG. 6, such a sub-board is no longer needed, and the connection structure between the camera module 30 and the board 300 is simplified, thereby affecting noise. Not only is it excellent in connectivity, it is also possible to miniaturize the overall pogo pin jig, thereby reducing the manufacturing cost. FIG. 6 is a schematic diagram schematically illustrating a position and a connection relationship between a connector of a camera module and a main board in the inspection apparatus of FIG. 4.

Here, the coupling of the guide jig 100 and the cover jig 200 is made by rotating the cover jig 200 about the rotation shaft 120 formed on one side of the guide jig 100. Here, the guide jig 100 further includes a coupling member 130 formed on the other side of the guide jig, and the guide jig 100 and the cover jig 200 are in close contact with each other by the coupling member 130. More preferably combined.

That is, in the related art, since the space between the guide jig and the cover jig is narrow, there is a problem that the workability is remarkably decreased when the operator mounts the camera module onto the guide jig. Since the cover jig can be completely rotated about the rotating shaft formed on one side of the camera module, the overall workability can be improved.

Meanwhile, in the exemplary embodiment of the present invention, the cover jig 200 is rotated about the rotation shaft 120 formed on one side of the guide jig to form a coupling of the guide jig and the cover jig, but the present invention is not limited thereto. . That is, the cover jig 200 and the guide jig 100 may further include a plurality of guides (not shown) vertically formed between the cover jig and the guide jig, and move the cover jig 200 in the vertical direction. They may be combined with each other, and may also be configured such that the above rotary coupling and vertical coupling are properly combined.
