Description

Socket for testing Camera Module

The present invention relates to a socket for inspecting a camera module. More specifically, the present invention relates to a socket for inspecting a camera module, in which a double acting type cylinder is installed in an actuator installed inside with air pressure to move forward and backward, When the camera module pusher and the pin block are lowered while the camera module is seated with the coil spring installed near the vertex of the bottom of the camera module base, the camera module is pressed, The connector connected to the slightly bent flexible circuit board connected to the camera module in parallel with the camera module mounted on the base seating surface is flatly spread so that the measuring pin of the metal block of the pin block is electrically connected to the correct position of the connector, The module can be inspected The present invention relates to a socket for inspecting a camera module.

Generally, a camera module using a CMOS or a CCD image sensor is used as an electronic camera. After assembling a CMOS or CCD image sensor, a lens and a housing on a printed circuit board, a flexible printed circuit board And electrically connected to the circuit board of the camera main body via the flexible printed circuit board, and it is checked whether the camera module operates normally or not after the manufacture.

Particularly, in the operation of the camera module, the relation between the position and the optical axis of the image sensor of the camera module is very important. This is because, if the position of the image sensor is finely twisted and the center of the image sensor does not coincide with the optical axis, or if the optical axis is inclined with respect to the image sensor, the reproduced image may have vignetting, The brightness and the contrast of the image become ununiform, which is a very unstable image.

Recently, as the size of the image sensor becomes smaller, the influence of the joining tolerance of the components such as the image sensor and the housing on the overall performance of the final camera module becomes relatively large.

That is, as the size of the image sensor is reduced, the importance of aligning the optical axis in the manufacture of the camera module is increasing, and the performance of the measuring equipment is also required to be improved.

Referring to FIGS. 6 and 7, a camera module 18 to be inspected using a socket for inspecting a camera module according to the present invention is configured such that a connector 191 is connected to an FPCB 19.

In order to perform an accurate inspection of the camera module 18 according to the present invention, the measuring pins of the conductive metal material of the pin block 8 are electrically and precisely aligned with the connectors 191 of the camera module 18 .

However, the camera module 18 mounted on a smart phone or the like is small in size and the connector 191, which is electrically connected to the metallic measuring pins having the conductivity of the pin block 8 for inspection, is mounted on the FPCB 19 The metal measuring pins of the pin block 8 do not accurately connect to the connector 191 when the FPCB 191 can not be maintained in a flat state as shown in FIG. A problem that can not be solved occurs.

The camera module 18 to be inspected according to the present invention should be placed in a state of maximum flatness without bending the FPCB 19 in the camera module seating portion 21 of the camera module base 20. [

However, since the FPCB 191 electrically connecting the connector 191 of the present invention to the camera module 18 is made of a flexible material, the FPCB 19 portion of the camera module 18 requiring inspection The metallic measuring pins of the pin block 8 are not brought into contact with the position of the connector 191 and are not precisely electrically connected to the camera module 18, There arises a problem that it is delayed in time.

In order to solve such a problem, a coil spring 17 is provided in the vicinity of the upper vertex of each of four camera module pushers 16, and the other end of the coil spring 17 presses the camera module pusher 16 to the upper base 14). The camera module pusher 16 is configured to descend downwardly due to the length of the coil spring 17 so that the position of the camera module 18 before the metallic measuring pins of the pin block 8 are in electrical contact with the connector 191 .

One coil spring 22 is provided on the bottom surface of the camera module base 20 in the vicinity of four lower vertexes and the other end of each coil spring 22 is attached to the lower base 28 to be bent Thereby helping the FPCB 19 to be spread well.

Even if the FPCB 19 of the camera module 18 is not flatly spread and the FPCB 19 is slightly bent as shown in FIG. 7, the camera module 18 having the bent FPCB 19 may be bent, The flow plate 10 disposed under the pin block 8 is fixed to the bent FPCB 19 while the camera module pusher 16 is first fixed while pressing the camera module 18 after the camera module push- The camera module 18 mounted on the mounting surface of the camera module base 20 by the coil spring on the bottom surface of the camera module base 20 and the pin block 8 are parallel to each other So that the measuring pins come into contact with the precise position of the connector 191 and are electrically connected precisely.

If the actuators 30 and the upper base 14 are lowered in the downward direction unless the springs 17 and 22 are provided in the camera module pusher 16 and the camera module base 24, The module pusher 16 prevents the camera module 18 from being moved by fixing it preferentially and the measuring pins of the conductive metal material of the pin block 8 are electrically connected to the connector 191. [

If the camera module pusher 16 fixes the camera module 18 and the measuring pins of the conductive metal material of the pin block 8 are not connected to the connectors 17 and 22, (191).

However, if the FPCB 19, which electrically connects the connector 191 to the camera module 18, is bent, the measuring pins of the pin block 8 can not be accurately positioned to be connected to the connector 191 So that the measurement pin and the connector can not be electrically connected to each other. As a result, the camera module 18 can not be inspected properly and the inspection of the camera module 18 is delayed.

6 and 7 show a front view and a rear view of a camera module 18 according to the present invention before and after the camera module base 20 is seated.

FIG. 8 is an internal plan view showing a double-acting cylinder for moving the actuator from side to side in a socket for inspecting a camera module according to the present invention.

8, the double acting type cylinder 36 for moving the actuator 30 according to the present invention to the left and right is provided therein. The double acting type cylinder 36 is provided with a forward pipe 38 and a backward fighter 40 and a rod 43 connected to the actuator 30 of the present invention.

9 is an internal plan view showing an up-down cylinder for moving an actuator up and down in a socket for inspecting a camera module according to the present invention.

Referring to FIG. 9, an up-down cylinder 46 for vertically moving the actuator 30 according to the present invention is installed inside the body portion 32.
