[ embodiment 1 ]
In the following, a test apparatus for testing a display module is described as an example, but the present invention is not limited to this, and for example, an electronic device having a flexible circuit board other than a display module may be tested.
As shown in fig. 1 to 3, a test apparatus 100 according to embodiment 1 of the present invention is an apparatus for testing a display module 200 such as a liquid crystal display module or an organic EL display module. In the test, a Flexible Printed Circuit (FPC) 201 of the display module 200 to be tested is connected to a connector of the test apparatus 100, and then the test apparatus 100 transmits various electric signals to the display module 200 to be tested through the Flexible Printed Circuit 201, thereby performing a series of performance index tests on the display module 200.
The test apparatus 100 includes: a base 1; a cover plate 2 provided on the base 1 in a rotatable manner with respect to the rotation shaft 21; and a test circuit board 3 detachably mounted on the cap plate 2.
The base 1 is, for example, an elongated shape that is long in the x direction, and has a first portion 11 located on one side in the x direction (for example, the right side in fig. 1) and a second portion 12 located on the other side in the x direction (for example, the left side in fig. 1), wherein the thickness of the first portion 11 (i.e., the height in the z direction) is larger than the thickness of the second portion 12, that is, the upper surface of the first portion 11 is higher than the upper surface of the second portion 12.
A groove 13 for placing a flexible circuit board 201 provided in the display module 200 is formed on the upper surface of the first portion 11 of the base 1. The groove 13 extends in the general x-direction, and the width of the groove 13 coincides with the width of the flexible circuit board 201, that is, has substantially the same width. Further, the depth of the groove 13 is not particularly limited as long as the groove 13 can function to position the flexible circuit board 201. The material of the base 1 is not particularly limited, and may be any material that can support the cover 2, the test circuit board 3, and the flexible circuit board 201 and does not affect transmission of electrical signals.
The cover 2 is a plate-like body for supporting and fixing the test circuit board 3, is provided on the upper surface of the second portion 12 of the base 1 via a rotating shaft 21 extending in the y direction orthogonal to the x direction, and is configured to be rotatable with respect to the rotating shaft 21, so that the cover 2 can be closed with respect to the base 1 (i.e., the state shown in fig. 1 and 2) or opened (i.e., the state shown in fig. 3). The material of the cover 2 is not particularly limited as long as it can support the test circuit board 3, and may be the same material as the base 1 or a different material from the base 1.
The test circuit board 3 is used for generating various test electric signals, and is detachable from the cover plate 2, so that different test circuit boards 3 can be used according to different test objects. As shown in fig. 4, the test circuit board 3 has a connector 31 formed on a surface thereof facing the recess 13, and the connector 31 is located at a position where it can be electrically connected to a connection terminal 201a on the flexible circuit board 201 to be tested placed in the recess 13 in a state where the cover 2 is fitted to the base 1 by being rotated, and protrudes toward the connection terminal 201a on the flexible circuit board 201 (i.e., protrudes downward from the back surface of the test circuit board 3). Thus, in a state where the cover 2 is fitted to the base 1, the connector 31 can protrude into the concave groove 13 and be electrically connected to the connection terminal 201a on the flexible circuit board 201 placed in the concave groove 13. Here, the amount of protrusion of the connector 31 is not particularly limited as long as reliable electrical connection with the connection terminal 201a on the flexible circuit board 201 can be ensured. Further, the connector 31 and the connection terminal 201a of the flexible circuit board 201 may be electrically connected reliably by appropriately adjusting the depth of the recess 13, the height of the connection terminal 201a of the flexible circuit board 201, and the like without protruding the connector 31. In the present invention, a conventional test connector may be used as the connector 31, and may have a plurality of pin points, metal probes, or the like.
According to the test apparatus 100 of embodiment 1, the concave groove 13 as described above is formed in the base 1, whereby the flexible circuit board 201 can be positioned, the influence of light and space can be eliminated, and the connector 31 of the test circuit board 3 can be easily and accurately aligned with the connection terminal 201a on the flexible circuit board 201.
Furthermore, since the connector 31 of the test circuit board 3 and the connection terminal 201a of the flexible circuit board 201 can be electrically connected by rotating the cover 2 to cover the base 1, the connector 31 of the test circuit board 3 and the connection terminal 201a of the flexible circuit board 201 can be prevented from being damaged by an external force without inserting or pulling the flexible circuit board 201, thereby increasing the service life of the connector 31 and preventing the electronic devices such as the display panel 200 from being damaged by a short circuit or the like.
In addition, since the existing circuit board 3 for test can be used, cost can be saved. Further, since the test circuit board 3 is detachable from the cover plate 2, different test circuit boards 3 can be used according to different test objects, and the mounting and dismounting can be performed more easily than the case where the test circuit board 3 is provided inside the base 1.
As shown in fig. 2, in embodiment 1, an elastic member 14 is provided in the second portion 12 of the base 1, and the elastic member 14 applies an upward force to an end portion (i.e., a left end portion in fig. 2) of the cover 2 located on the opposite side of the connector 31 with respect to the rotation shaft 21. By providing such an elastic member 14, at least a part of the test circuit board 3 mounted on the cover 2 can be brought into pressure contact with the base 1, and the connector 31 of the test circuit board 3 and the connection terminal 201a on the flexible circuit board 201 can be reliably electrically connected. The elastic member 14 is not particularly limited, and may be a spring or another member made of an elastic material as long as it can apply an upward force to the end portion of the cover 2.
In the present invention, the elastic member 14 as described above is not provided, but instead, a torsion spring (not shown) that generates a rotational force for covering the cover 2 to the base 1 may be attached to the rotation shaft 21. This also enables the connector 31 of the test circuit board 3 mounted on the cover 2 to be electrically connected to the connection terminal 201a of the flexible circuit board 201 with certainty. In the present invention, the elastic member 14 and the torsion spring may be provided at the same time.
In embodiment 1, the upper surface of the first portion 11 of the base 1 is higher than the upper surface of the second portion 12, but the present invention is not limited to this, and the upper surface of the first portion 11 of the base 1 and the upper surface of the second portion 12 may be the same height as long as the connector 31 of the test circuit board 3 and the connection terminal 201a on the flexible circuit board 201 can be electrically connected reliably.
[ embodiment 2 ]
In embodiment 1, the force for covering the cover 2 to the base 1 is generated by the elastic member 14 or the torsion spring, but the present invention is not limited to this, and the force for covering the cover 2 to the base 1 may be generated by a magnetic body.
In embodiment 2, as shown in fig. 5, a pair of first magnetic bodies 15 are provided on, for example, both sides in the y direction on the upper surface of the first portion 11 of the base 1, and a pair of second magnetic bodies 25 are provided at the right end of the cover 2 at positions facing the first magnetic bodies 15. A force for covering the cover 2 on the base 1 is generated by the magnetic force between the first magnetic body 15 and the second magnetic body 25. This allows the connector 31 of the test circuit board 3 mounted on the cover 2 to be electrically connected to the connection terminal 201a of the flexible circuit board 201 with certainty.
The present invention is not limited to the above configuration, and any number of first magnetic bodies 15 and second magnetic bodies 25 may be provided as needed. The first magnetic body 15 and the second magnetic body 25 may be provided together with the elastic member 14 and/or the torsion spring according to embodiment 1.

Fig. 6 is a plan view of the first portion 11 of the base 1 in the test apparatus 100 according to embodiment 3. As shown in fig. 6, in embodiment 3, a first slider 111 and a second slider 112 that are slidable in the y direction (i.e., in the width direction of the groove 13) along the upper surface of the first portion 11 of the base 1, and a protruding member 113 that protrudes from the upper surface of the first portion 11 on the side of the cover plate 2 of the first slider 111 and the second slider 112 are provided. Thereby, the groove 13 is formed surrounded by the first slider 111, the second slider 112, and the protruding member 113. The width W of the groove 13 can be changed by sliding the first slider 111 and the second slider 112 relatively.
According to the test apparatus 100 of embodiment 3, the width of the groove 13 can be changed as needed, so that a plurality of kinds of electronic devices having different widths of the flexible circuit board can be tested.
The projection member 113 is not limited to being fixed, and may be slidable in the x direction. By providing the projection member 113 to be slidable in the x direction, the position of the connection terminal 201a of the flexible circuit board 201 in the x direction can be changed, and it is possible to cope with a plurality of types of test circuit boards 3 having different positions of the connector 31.
In addition, the thicknesses of the first slider 111, the second slider 112, and the protrusion member 113, that is, the depth of the groove 13 are not particularly limited as long as the groove 13 can function to position the flexible circuit board 201.
[ embodiment 4 ]
Fig. 7 is a plan view of the first part 11 of the base 1 in the test apparatus 100 according to embodiment 4. As shown in fig. 7, in embodiment 4, a stopper 19 for limiting the position of the connection terminal 201a of the flexible circuit board 201 in the groove 13 is provided in the groove 13. The stopper 19 is, for example, a block body having a thickness substantially equal to the depth of the groove 13, and a side surface of the stopper 19 is in close contact with a side surface of the groove 13, so that the stopper 19 can be moved by a force of a predetermined amount or more. By moving the stopper 19 in the groove 13, the position of the connection terminal 201a of the flexible circuit board 201 in the groove 13 can be adjusted, and the flexible circuit board can be more accurately connected to the connector 13, and a plurality of types of test circuit boards 3 having different positions of the connector 31 can be handled.
In addition, the utility model is not limited to providing one limiting member 19 capable of moving in the groove 13, the testing device 100 may also have a plurality of limiting members with different lengths in the x direction, and by placing the limiting members with different sizes on the top of the groove 13, the positions of the connection terminals 201a of the flexible circuit board 201 in the groove 13 can be adjusted, so that the flexible circuit board can be more accurately connected with the connector 13, and the testing device can cope with a plurality of testing circuit boards 3 with different positions of the connector 31.
