Description

Camera Module Automatic TestSocket}

The present invention relates to a slide-type automatic test socket for testing the operation of an image sensor of a camera module and a circuit board thereof. More specifically, the connection movement section between the camera module and the test pin block is extremely shortened to shorten the test time and The present invention relates to a camera module automatic test socket that improves work efficiency and further minimizes the size of the test socket.

In general, a camera module (hereinafter abbreviated as'module') consisting of a PCB board on which an image sensor, camera lens, connector, etc. is installed is essential to a test process for normal operation before being used (assembled and installed) in mobile phones or digital cameras. And the test is being carried out by the camera module test socket.

Here, the camera module test socket, which is the background of the present invention, is mainly used as a passive test socket that is manually operated by coupling a module test bracket for mounting a conventional module and a top plate provided with a pin block so as to be rotatable in the form of a clamp by a hinge. Became,

In recent years, it is composed of a module test bracket for mounting the module and a movable top plate installed with an actuator at a certain distance along a straight line at the rear.

The top plate moves in the front direction by a cylinder and is located on the same line as the module test bracket, and the top plate is lowered onto the module test bracket by both lower side lifting and lowering cylinders, so that the measurement pin of the pin block is bound to the connector of the module. It is using an automatic test socket that is automatically operated.

Here, the background technology of the present invention belongs to the automatic test socket described later, and the automatic test socket described above is moved to a module test bracket of a fixed configuration, and the top plate of the configuration is moved by a cylinder by a certain distance along the actuator. As a method of connecting and operating, the test time was short compared to the passive test socket, and the test work efficiency was excellent.

However, the above-described background technology has been pointed out that test precision decreases and test defects increase due to the long section operation of the cylinder rod as well as the top plate, and furthermore, the volume of the socket is unnecessarily enlarged due to the long moving structure.

To explain this in more detail, a camera module consisting of a PCB board with a precision installed small camera lens and connector is very small and very sophisticated, so it is sensitive to small impacts or long movements. Furthermore, the pin block connection error of the top plate with the connector of the camera module There was a great concern that it would be easily damaged or damaged if it occurred.

Therefore, looking at the above background technology (automatic test socket) again under the above conditions,

The structure of the method of operating the top plate by automatically moving the top plate to the cylinder with the fixed position module test bracket is essentially designed with the rear top plate at a distance from which initial interference can be avoided so that the module test bracket can be placed easily. At the same time, a cylinder having a length that can move the top plate by the above-described distance must be designed exclusively. Therefore, in the above background technology, the moving distance of the top plate and the operating length of the cylinder rod for its operation are unnecessarily long, so the accuracy of the contact between the module and the top plate (positive position) is poor, and furthermore, vibration and noise are generated in the top plate when used for a long time, and straightness. There was a concern that could impede it.

In addition, the problem of the moving structure of the top plate could be an obstacle to the module test time and the number of tests in the long term.

In the above-described automatic test socket, the above-mentioned problem is solved only when the interconnection movement distance between the module test bracket and the top plate in which the module is placed is shorter than before. Currently, a lot of technology and effort are urgently required to solve the above problem. .

Next, an embodiment of the present invention will be described based on the above-described configuration as follows. However, in order to help the understanding of the present invention, the mobile action system and the movement reaction system will be described by limiting them to the first example most preferred in the present invention.

The camera module automatic test socket according to the present invention allows the top plate 3 and the module test bracket 5 to simultaneously move (approach) to one point when the module is placed in the module test bracket 5 so that the test is performed quickly/accurately. It is one device.

First, for module testing, the module m is placed in the module groove 51 of the module test bracket 5.

In this case, in the present invention, a module fixing unit 6 is added to one corner of the module groove 51 so that the module m can be accurately positioned in the module groove 51.

The module fixing unit 6 is installed at the edge of the module test bracket 5 and has a module fixing block mounting table 62 having a guide space 61 therein, and an upper module fixing block installed in the guide space 61.

(See Figures 9 to 12)

In the module fixing unit 6 of the above configuration, as shown in FIG. 12, in the initial position state of the module test bracket 5 (the module is placed in standby state), the guide pin 64 under the guide block 65 is It is located on the side of one guide 11' so that the upper module fixing block 63 is located in a position that is spaced apart from the edge of the module groove 51. At this time, the spring 66 posted between the guide block 65 and the inner circumferential surface of the guide space 61 is compressed by the position of the guide block 65, the guide pin 64, and the module fixing block 63. Have.

And when the module (m) is placed in the module groove (51) and the module test bracket (5), which will be described below, moves in one direction, the module fixing unit 96 moves simultaneously and the lower guide pin 64 is moved to the base (1). At the same time, the spring 66 moves the guide block 65 and the upper module fixing block 63 in the direction of the module groove 51 by the elastic force of the guide block 11 ′. ), the corner pressing groove 67 of the module fixing block 63 pushes the module (m) to the correct position of the module groove 951 so that an accurate and safe position is fixed.

In addition, the present invention constitutes a stop pin (21") whose length is adjusted by a screwing method at the end of the side moving block (21) (21') and the stop pin (21") toward the upper center of the base (1). A stop block (1') that limits the movement distance of the side is protruded to limit and adjust the movement distance of the side movement blocks (21, 21'), and furthermore, a rubber or a silicone, etc., to one side of the stop block (1') The same soft buffer member (1") is included to prevent a collision between the stop pin (21") and the stop block (1').

On the other hand, when the top plate 3 and the descending cylinder 31 move upward, the driving rack gears 25 and 25 ′ under the descending cylinder 31 are pinion gears 27 and 27 of the base 1 ') and at the same time, the pinion gears 27 and 27 ′ move the driven gears 43 and 43 ′ of the movement reaction system 4 in one direction, and the module test bracket 5 and the top plate (3) are simultaneously moved in opposite directions so that they are connected to each other at one point (test connection reference point: see Fig. 7(b)).

In other words, the moving action system 2 moves the top plate 3, the descending cylinder 31, and the driving gear 25 and 25' in one direction to the cylinder 24 as shown in Fig. 6(a). Then, the driven gears 43 and 43 ′ of the moving reaction system 4 in which the pinion gears 27 and 27 ′ meshed with the driving rack gears 25 and 25 ′ are meshed to the lower portion are recalled. The connector (m1) of the module (m) and the pin of the top plate (3) placed in the module test bracket (5) at one point by moving in the direction opposite to the direction of movement of the driving gears (25) (25') Block 32 is positioned on the same line.

And when the top plate 3 and the module test bracket 5 are positioned under the above condition, the descending cylinder 31 lowers the top plate 3 and connects one pin block 32 to the connector (m1) of the module (m). ) To perform module test by main PC.

Here, the present invention includes at least one positive positioning guide pin (3') as a lower outer periphery of the top plate (3) and at the same time, including a positive positioning guide groove (5') to the upper outer periphery of the module test bracket (5). When the top plate is lowered to the top of the module test bracket, the correct positioning guide pin (3') and the correct positioning guide groove (5') are interconnected to ensure the accuracy and stability of the connection between the top plate and the module test bracket. Plan to be able to.

In addition, when the module test is completed, the above series and processes are carried out in reverse order.

The embodiment of the present invention described above is intended to ensure various effects by extremely shortening the moving section for module testing in the automatic test socket. Summarizing this again through a graph indicating the moving distance and each position,

Conventionally, as shown in Fig. 7 (a), the module test bracket is positioned at one point'a', and the'a' point is set as the test connection reference point, and the other point'b' As a result, a top plate having a pin block that is moved and operated by a driving device is constructed so that the top plate moves reciprocally from the point'b' to the point'a' to repeatedly perform the test.

However, the present invention constitutes a module test bracket that can be moved to a point'a' in any one place and a top plate that can be moved to a point'b' in another place, as shown in FIG. By setting the test connection reference point at the center of the'point and'b' point, the module test bracket and the top plate move from the'a' and'b' points to the test connection reference point in the center at the same time to perform the test. Hired.

Therefore, in the present invention, it can be seen that the moving section partitioned between'a' and'b' based on the test connection reference point is significantly shortened compared to the moving section between'a' and'b'. Compared to the prior art, the short axis can secure movement stabilization and reliability of the top plate, cylinder, and guide means, etc., and furthermore, it has the expectation that the accuracy and precision of the module test and the miniaturization of the socket can be achieved.
