Description

[0001] A CAMERA MODULE [0002]

The present invention provides a camera module inspecting apparatus capable of efficiently placing a camera module at the time of inspection.

In recent years, a high-performance camera is mounted on a mobile device such as a smart phone, and an inspection device for checking electrical characteristics of a large number of camera modules has been used.

In the camera module, a plurality of lead terminals are exposed through the flexible cable from the camera body to the receptacle type connector. The camera module inspecting apparatus includes a camera module carrier for seating the camera module for inspection, and an inspection head having a plug-type connector inserted into the receptacle-type connector for receiving and receiving an electrical signal from a lead terminal of the camera module, .

The inspection of the camera module may be performed by first inserting the camera module into the seating portion of the camera module carrier, then placing the inspection head on the camera module carrier, then lowering the inserting portion, and inserting the plug connector into the receptacle connector.

When mounting the camera module to the camera module carrier for inspection automatically or manually, it is general that the space where the camera module is seated is made as small as possible for the close inspection. However, when the tolerance is small, it is advantageous for the close inspection. However, when the camera module is automatically or manually mounted, the camera module may be placed in a wrong position, which may cause an inspection error or damage to the inspection device.

An object of the present invention is to provide a camera module inspecting apparatus which can improve the accuracy of inspecting while ensuring the seating margin of the camera module.

A camera module inspecting apparatus having a plurality of inspecting contacts for solving the problems of the present invention includes a fixing member having a mounting portion on which the camera module is mounted and a mounting slider capable of guiding the camera module toward the mounting portion A module carrier; Wherein the inspection carrier includes a plurality of inspection pins which are supported by a plurality of inspection pins contacting the inspection targets to be able to move up and down to and away from the module carrier, wherein the detection slider and the inspection carrier are in contact with each other when moving down the inspection carrier, And a contact driving section for mutually moving the descending approach movement to the movement of the seating slider.

According to this, it is possible to increase the precision of inspection while increasing the seating margin of the camera module.

Wherein the contact driving unit includes a slider that is disposed on one of the seating slider and the inspection carrier and has a wall portion corresponding to a part of an outer surface of the camera module and is capable of approaching and separating the camera module toward the seating portion, And a movable member that is disposed on the other of the carriers and moves the slider toward the seating portion. In this case, when the slider moves, a part of the outer surface of the camera module is moved in the moving direction, thereby moving the camera module to the correct inspection position.

Wherein the slider includes a slider disposed at a predetermined distance around the seating portion and capable of moving horizontally toward the seating portion, wherein the movable member is in contact with the slope when the inspection carrier descends, And at least one protrusion for horizontally moving the protrusion toward the part. According to this structure, the slider can be moved in a simple structure.

Wherein the slider includes a slider disposed at a predetermined distance from the seating portion and rotatable with respect to the seating portion, and the movable member is in contact with the slope portion when the inspection carrier descends, And at least one protrusion that rotates and moves toward the lower portion. According to this structure, the slider can be moved in a simple structure.

Preferably, the slider includes an elastic body that elastically approaches and separates from the seating portion. According to this, the slider can be automatically returned to the original position when the inspection carrier is moved upward after the completion of the inspection.

According to the present invention, it is possible to maintain the precision of inspection while reducing the possibility that the camera module is not seated on the module carrier. That is, after inserting the camera module into the seating portion of a wide module carrier, the space of the seat portion is deformed when the inspection carrier is moved downward for inspection, and the mounted camera module moves to the correct inspection position during deformation of the seat portion The margin and inspection accuracy can be increased together.

Hereinafter, a camera module testing apparatus 1 according to the present invention will be described in detail with reference to the accompanying drawings.

Prior to the description, the following description will be made on the assumption that the X-axis is the lateral direction and the Y-axis is the vertical direction with respect to the front surface of the inspection apparatus.

The configuration of the inspection apparatuses according to the first and second embodiments of the present invention is described with the same reference numerals for the same names. However, the reference sliders for distinguishing the first and second embodiments are denoted by different reference numerals I will reveal it in advance.

FIG. 1 shows a camera module inspection apparatus 1 according to a first embodiment of the present invention. The camera module inspecting apparatus 1 comprises a module carrier 200 for placing the camera module 10 on a base 100 and a test carrier 100 mounted on the module carrier 200 for being moved up and down, (300).

The camera module 10 includes a camera body 12 and a connector 11 exposed to apply an electric signal to the camera body 12 as a small camera used in mobile devices such as a smart phone. The connector 11 is connected to the camera body 12 via a flexible cable. The connector 11 includes a plurality of receptacle-type contacts adapted to engage a plurality of plug-in contacts disposed in the inspection carrier 300. Of course, when the receptacle-type contacts are arranged in the inspection carrier 300, the connector 11 of the camera module 10 can arrange the plug-type contacts.

The base 100 serves as a support for mounting the module carrier 200 in a flat plate shape.

2, the module carrier 200 includes fixing members 240 and 250 having a mounting portion 240 for mounting the camera module 10 described above, and a mounting portion 240 for mounting the camera module 10, And a pair of seat sliders 220 and 222 that can guide the seat sliders 220 and 222 toward each other. The fixing members 240 and 250 are disposed on the rear side of the seating part 240 and the rear side of the main body 12 of the camera module 10, (Not shown).

The seat portion 240 is preferably defined as a portion forming a space in which both the main body 12, the connector 11 and the connecting portion 13 of the camera module 10 are to be located. That is, the seat portion 240 is defined as a portion, for example, a groove, which forms a space corresponding to the bottom surface and the side surface of the main body 12, the connector 11 and the connecting portion 13 of the camera module 10. Of course, it is also possible to ensure that only the space in which the main body 12 of the camera module 10 is to be located is defined exactly and the space in which the remaining connector 11 or the connecting portion 13 is located can be sufficiently placed. This is because the connector 11 and the connecting portion 13 may be automatically moved along with the movement of the camera module 10.

The fixed wall portion 250 serves to restrict the rear surface of the main body 12 from being separated from the seating portion 240 when the main body 12 of the camera module 10 is moved toward the seating portion 240. At this time, the fixing wall portion 250 may have a shape at least partially corresponding to the shape of the main body 12 contacting the portion contacting the rear surface of the main body 12. This limitation can be made to ensure that the camera module 10 is seated correctly in the seating portion 240 when the slider 220 of the seating slider pushes the camera module 10 into the seating portion 240.

The pair of seating sliders 220 and 222 includes a slider 220 spaced horizontally from the seating portion 240 of the fixing members 240 and 250 by a predetermined distance and horizontally slidable relative to the center, And guide grooves 222 for mounting and guiding the guide grooves 220. At this time, instead of the pair of seating sliders 220, one can be fixed to the seating portion 240, and only the other seating slider 220 can be horizontally moved. The seating slider 220 is disposed in the guide groove 222 as shown in FIG. 4, and is biased outward from the seating portion 240 by an elastic body 260 such as a spring. The slider 220 is forcibly moved to the left and right sides of the seating portion 240 by the movable member of the inspection carrier 300 described later, for example, a projection 320 such as a pin, As shown in FIG.

The slider 230 includes an inclined portion 232 that is lowered toward the left and right outside the seat portion 240. The inclined portion 232 is positioned so as to be in contact with the projection 320 of the inspection carrier 300 that approaches from the upper side to the lower side so that the projection 320 can push the slitter 230 toward the seat portion 240 .

The module carrier 200 may include apertures 220 through which the ends of the protrusions 320 of the inspection carrier 300 enter adjacent the left and right outer sides of the slider 230, have. The aperture 220 is for preventing the protrusion 320 from hitting another part when approaching the inspection carrier 300 downward.

The same effect can be obtained by protruding the projection 320 of the inspection carrier 300 instead of the slant portion 232 of the slider 230 such that the protrusion 320 of the inspection carrier 300 flares outward with respect to the seating portion 240.

The module carrier 200 is arranged in alignment with the alignment pins 310 of the inspection carrier 300 so that the connector 11 of the camera module 10 and the connector 11 of the inspection carrier 300, And includes a ball 210. Of course, the alignment holes 210 may be disposed in the inspection carrier 300 instead of being disposed in the module carrier 200, and the alignment pins 310 may be disposed in the module carrier 200.

The module carrier 200 includes a second connector 270 having a plurality of contacts for transmitting an inspection signal transmitted from an inspection circuit (not shown) to the inspection carrier 300 side. The second connector 270 protrudes adjacent to the fixed wall portion 250. The second connector 270 engages the third connector 370 of the inspection carrier 300, which will be described later, upon the descent of the inspection carrier 300, and transfers the inspection signal to the inspection carrier 300.

3 is a view showing the inspection carrier 300 of the inspection apparatus 1 according to the first embodiment of the present invention. The inspection carrier 300 includes a module receiving portion 340 for receiving and supporting the main body 12 of the camera module 10, a test pin 311 inserted into the connector 11 of the camera module 10, A protrusion 320 such as a pin that is inserted into the hole 220 after the slider 230 contacts the slider 230 of the module carrier 200 and the aligning hole 210 inserted into the alignment hole 210 of the module carrier 200 And includes a pin 310.

The module accommodating portion 340 has a shape corresponding to the outer shape of the main body 12 of the camera module 10 that is seated in the seating portion 240 of the module carrier 200. That is, since the main body 12 of the camera module 10, which is seated in the module accommodating portion 340, protrudes higher than the height of the connector 11, when the inspection carrier 300 is mounted on the module carrier 200 The main body 12 of the camera module 10 is received from above so as not to interfere with the downward approach of the module 10. The module accommodating portion 340 may also support the body 12 of the camera module 10 so as not to move when the lowering of the inspection carrier 300 is completed.

The inspection pin 311 is lowered and inserted into the connector 11 of the module carrier 200 for inspection. As the inspection pin 311, for example, a pogo pin (not shown) in which the upper and lower plungers are partially inserted into the barrel with a spring interposed therebetween can be applied.

A movable member, that is, a projection 320 such as four pins, projects toward the inclined portion 232 of the slider 230 of the module carrier 200 disposed at the lower portion. The protrusion 320 pushes the slider 230 toward the seat portion 240 while contacting the slope portion 232 of the slider 230 as the inspection carrier 300 descends.

The alignment pins 310 protrude toward the alignment holes 210 of the module carrier 200 and are inserted into the alignment holes 210 when the inspection carrier 300 is lowered.

The inspection carrier 300 includes a third connector 370 that engages a second connector 270 of the module carrier 200.

The inspection carrier 300 includes a printed circuit 380 that electrically connects the third connector 370 and the inspection pin 311 to each other. The printed circuit 380 may include components such as resistors (not shown) and capacitors (not shown) as needed.

The contact actuators 230 and 320 shown in Figures 1-3 include the slider 230 of the module carrier 200 and the movable member of the inspection carrier 300, The contact driving parts 230 and 320 can obtain the same effect by disposing a projection on the module carrier 200 and a slider on the inspection carrier 300, as opposed to the shapes shown in Figs.

It is also possible to replace the role of the fixed wall portion 250 by adding a wall portion substantially perpendicular to the inner wall portion of the left and right sliders 230 shown in FIGS. 1 to 3 toward the seating portion 240.

The inspection operation of the inspection apparatus 1 according to the present invention will now be described with reference to FIGS. 4 and 5. FIG.

First, the camera module 10 is mounted for inspection in a state where each slider 230 of the module carrier 200 is open. At this time, since the camera module 10 does not have to be placed in the correct seating portion 240, the camera module 10 can be easily mounted in a relatively large space.

Next, as shown in Fig. 4, the inspection carrier 300 is rotated by about 90 degrees to be positioned at the top of the module carrier 200.

5, when the inspection carrier 300 is moved downward (V), the second connector 270 of the module carrier 200 is first engaged with the third connector 370 of the inspection carrier 300, The projection 320 of the inspection carrier 300 contacts the inclined portion 232 of the slider 230. At this time, when the protrusion 320 is continuously lowered, the camera module 10 in which the slider 230 is horizontally moved (H) by pressing the slider 230 toward the seat portion 240 is placed on the seat portion 240 .

The protrusion 320 is further lowered to enter the opening 220 and the connector 11 of the camera module 10 accurately seated in the seating portion 240 is engaged with the inspection pin 311 of the inspection carrier 300, A signal can be applied. As a result, the inspection signal is sequentially transmitted to the inspection circuit (not shown), the second connector 270, the third connector 370, the PCB 380, the inspection pin 311, the camera module connector 11, 13, and the camera module body 12, respectively.

6 and 7 show an apparatus 1 for inspecting a camera module according to a second embodiment of the present invention. As shown, the configuration of the inspection carrier 300 has a configuration similar to that of the inspection carrier of the first embodiment, and a description thereof will be omitted.

As shown, the module carrier 200 includes a rotating slider 430 hinged about a seating portion 240 to be rotatable. The rotation slider 430 is disposed in a rotation guide groove 436 formed to be rotatable. The rotating slider 430 is biased by an elastic body (not shown) such as a spring in a direction in which the inner wall portion 431 of the rotating slider 430 moves away from the seating portion 240 about the hinge axis 432. The rotary slider 430 is formed with a projection groove 434 for guiding and guiding the projection 320 of the inspection carrier 300. The inner wall portion 431 of the rotary slider 430 rotates about the hinge axis 432 in the direction of approaching the seating portion 240 when the projection 320 is lowered. Therefore, the space formed by the inner wall portion 431 of each rotary slider 430 is widened before inspection, and becomes narrower as the protrusion 320 of the inspection carrier 300 is lowered at the time of inspection. As a result, the camera module 10 placed in a wide space before the inspection can be moved to the position of the narrow (correct) seating portion 240 by the rotation of the rotary slider 430 during inspection.
