Description

Suction Camera Module Test Socket

The present invention relates to an adsorption camera module test socket, and more particularly, an adsorption type that can be mounted on the socket itself and mounted on the socket directly from the adsorption inversion tray to reduce mechanical cost and reduce the overall structure of the equipment. Relates to a camera module test socket.

In general, a small camera is mounted on a mobile communication terminal to record and store a video and an image.The small camera is equipped with a CMOS or CCD image sensor on a printed circuit board, is assembled in a lens and a housing, and then electrically connected to the outside. It is manufactured by connecting with flexible printed circuit board.

Since the camera module is mounted inside a relatively narrow limited space of the mobile phone, the size of the lens and the PCB is extremely small, and the connector printed on the PCB is also formed with relatively fine detail.

Therefore, the PCB connected to the lens as described above is extremely difficult to measure the electrical connection state after fabrication and assembly thereof. The socket having a measuring pin is used to determine whether the small lens and the connector are in poor connection state. The conventional socket has a base frame and a cover frame coupled to the base frame to be rotatable by a hinge. Is done.

The base frame and the cover frame are rotatably coupled by a hinge to form a socket, and the camera module is seated therein. The socket is provided with a test pin block and a connection pin block to insert the camera module into the main board. Tested by connecting to.

The auto focus equipment 8 is used to assemble and test the camera module. More specifically, the auto focus apparatus 8 adjusts the optical distance between the lens module 1a and the sensor module 1b to obtain an optimal image. It is the equipment to find the assembly status that can be.

As shown in FIG. 1, in the case of the mobile phone camera module 1 illustrated in the related art, electrical connection is made with the direction of the lens module 1a in which the field of view of the camera module 1 is formed, the test probe, and the like. The directions of the connectors 1d are opposite to each other.

Therefore, a test probe such as an automatic focusing device or the like can be easily connected to the connector 1d from the direction opposite to the direction of the lens module 1a, so that it can be connected without disturbing the field of view formed by the lens module 1a. Can be. As a result, it is not necessary to add a design change etc. to the structure of a normal probe socket.

2 is a conceptual diagram illustrating an operation of testing a conventional mobile phone camera module having a test probe with opposite directions of a connector and a lens.

As shown in FIG. 2, the auto focus equipment 8 includes a test probe 6 and a main PC 7 connected thereto. First, when the mobile phone camera module having the opposite direction of the lens and the connector is placed on the test probe socket 5, the connector (not shown) and the test probe socket 5 on the opposite side of the lens module 1a are The pins are electrically connected.

At this time, since the direction of the lens module 1 and the direction of the pins of the connector 1d are opposite to each other, even if a separate configuration is not provided inside the test probe socket 5, the lens module 1a is disposed from the opposite side of the lens module 1a. The connector 1d and the test probe socket 5 are connected.

That is, as shown in FIG. 1B, it can be seen that the electrical wiring structure 8 in the test probe socket 5 is very simple. Thereafter, the test probe 6 is driven up and down to electrically connect the lower side of the test probe socket 5 and the probe pin 9 of the test probe 6.

The main computer 7 reads the image present in the test chart 4 while moving the lens module 1a up and down under the standard illumination 3, and then processes the image data generated by the sensor module 1b to optimize the image. Find the point where this is obtained.

As described above, when the direction of the lens module 1a such as the conventional camera module 1 shown in FIG. 2 and the direction of the connector 1d are opposite to each other, simple electrical wiring as shown in FIG. The test probe socket 5 having the structure 5a makes it easy to electrically connect the mobile phone camera module 1 and the test probe 6 of the autofocus device 8.

However, in the case where the direction of the lens module and the connector of the mobile phone camera module are directed in the same direction as shown in FIG. 2, there is a problem in testing the mobile phone camera module with the auto focus device.

That is, since the connector is facing the same direction as the lens module, when using a conventional test probe socket, the test probe of the auto focusing equipment should eventually be connected to the connector through the test probe socket in the same direction as the lens. The field of view formed by the lens module may be disturbed.

Even when the direction of the lens module and the connector of the mobile phone camera are the same, in order to electrically connect the test probe of the auto focus device to the sensor module on the opposite side of the lens module, it is necessary to modify the configuration of the auto focus device. As a result, difficulties in developing standardized autofocus equipment have arisen.

In order to solve this problem, even if the lens and the connector of the camera module used in the mobile phone in the Republic of Korea Patent No. 10-0874851 facing the same direction, the test probe of the auto focus equipment from the opposite direction of the camera lens A "portable camera two-stage probe socket" can be connected to the module.

The board and the lower printed circuit board are installed so that the test probe can be connected to the connector in any of the upper and lower directions. However, the upper printed circuit board and the lower printed circuit board are used so that the structure is complicated and the components are doubled. There was a problem.
