[0029] Example:

[0030] Figure 1 is a schematic diagram of a plug-in structure for a display module provided by an embodiment of the utility model, such as Figure 1 As shown, the plug-in structure includes a support seat 1 and a drive assembly 2 .

[0031] The driving assembly 2 includes a three-axis correction mechanism 21, a driving mechanism 22 and a clamp 23. The three-axis correction mechanism 21 is located on the support seat 1, and the output end of the three-axis correction mechanism 21 is connected to the driving mechanism 22 to drive the driving mechanism 22 to move along the X-axis direction, move along the Y-axis direction and rotate in the corresponding plane. The output end of the driving mechanism 22 is connected to the clamp 23 to drive the clamp 23 to move along the Z-axis direction. The clamp 23 is used to clamp the plug connector 200 (the plug connector 200 is perpendicular to the Z-axis direction).

[0032] For a plug-in structure for a display module provided by an embodiment of the utility model, first, the support seat 1 is arranged on the detection station, and the plug-in connector 200 is clamped by the fixture 23 (at this time, another plug-in connector 200 is connected and conducted with the signal generator). Then, the display module 100 is placed on the assembly plane, at this time, the assembly plane is perpendicular to the Z-axis direction. Then, according to the position of the assembly plane on the Z-axis, the driving mechanism 22 drives the plug-in connector 200 to move along the Z direction to the assembly plane. And, according to the coordinate position corresponding to the interface on the display module 100, the plug-in connector 200 is driven by the three-axis correction mechanism 21 to move in the X-axis direction, move and rotate in the Y-axis direction on the assembly plane, thereby compensating for the position error of the plug-in connector 200 and the interface in the assembly plane, so that the driving mechanism 22 drives the fixture 23 and the plug-in connector 200 to move accurately, and finally completes the automatic plug-in, avoiding the problem that the accuracy of manual plug-in is difficult to control and the efficiency is low. After the plugging is completed, the display module 100 is lit, and the detection equipment on the detection station performs a display performance test on the display module 100. After the test is completed, the three-axis correction mechanism 21 drives the plug connector 200 to reset and removes the tested display module 100. Similarly, the next display module 100 is transported for testing again.

[0033] That is to say, the plug-in and unplugging structure for the display module provided by the embodiment of the utility model can enable the plug-in terminal 200 to move accurately, thereby completing automatic plug-in, which not only improves the detection efficiency but also avoids the problem of loss of the display module 100.

[0034] It should be noted that when placing the display module on the assembly plane, due to the error generated during placement, the projections of the display module 100 and the plug connector 200 on the assembly plane are spaced and deflected, so the three-axis correction mechanism 21 is required to perform correction on the plane. For subsequent different display modules 100, the driving stroke of the driving mechanism 22 can remain consistent.

[0035] Exemplarily, the driving mechanism 22 may be a cylinder or a linear module, or other driving mechanisms, which is not limited in the present invention.

[0036] In one implementation of the utility model, the three-axis correction mechanism 21 includes an X-axis drive module, a Y-axis drive module and a θ-axis drive module. The X-axis drive module is located on the support seat 1. The output end of the X-axis drive module is transmission-connected to the Y-axis drive module to drive the Y-axis drive module to move along the X-axis direction. The output end of the Y-axis drive module is transmission-connected to the θ-axis drive module to drive the θ-axis drive module to move along the Y-axis direction. The output end of the θ-axis drive module is transmission-connected to the drive mechanism 22 to drive the drive mechanism 22 to drive the plug connector 200 to rotate in the corresponding plane.

[0037] In the above embodiment, the X-axis driving module, the Y-axis driving module and the θ-axis driving module can respectively realize the movement of the plug connector 200 in the X direction, the movement in the Y direction and the rotation, so that the plug connector 200 is automatically accurately aligned with the interface and plugged in.

[0038] Exemplarily, the X-axis driving module and the Y-axis driving module may be linear motors, and the θ-axis driving module may be a motor.

[0039] It should be noted that in other embodiments of the present invention, the three-axis correction mechanism 21 may also include two X-axis drive modules and one Y-axis drive module (rotation is achieved through the drive speed difference between the two X-axis drive modules), and the present invention does not impose any limitation on this.

[0040] Figure 2 Schematic diagram of the structure of the connecting seat provided by the embodiment of the utility model. Figure 2 As shown, the driving assembly 2 also includes a connecting seat 24, and the connecting seat 24 includes a carrier plate 241 and a connecting plate 242 that are connected to each other. The carrier plate 241 is located on the output end of the three-axis correction mechanism 21, and the driving mechanism 22 is located on the connecting plate 242. Among them, the carrier plate 241 plays a role in connecting the output end of the three-axis correction mechanism 21 with other components, and the connecting plate 242 plays a role in supporting the driving mechanism 22. The connection between the three-axis correction mechanism 21 and the driving mechanism 22 can be conveniently realized through the carrier plate 241 and the connecting plate 242.

[0041] Furthermore, the connecting plate 242 includes a first plate body and a second plate body that are vertically connected to each other. The first plate body is fixed in parallel on the carrier plate 241, and the driving mechanism 22 is located on the second plate body. The first plate body can ensure a reliable connection between the connecting plate 242 and the carrier plate 241, and the second plate body extends out of the first plate body to facilitate the installation of the driving mechanism 22.

[0042] Exemplarily, the first plate body and the carrier plate 241 are connected by a plurality of bolts.

[0043] Exemplarily, the connecting plate 242 also includes a rib plate 243, which is perpendicular to the first plate body and the second plate body, and the two side edges of the rib plate 243 are respectively fixedly connected to the first plate body and the second plate body, thereby increasing the connection strength between the first plate body and the second plate body through the rib plate 243.

[0044] In this embodiment, the clamp 23 includes a finger cylinder 231, so that the plug connector 200 can be reliably clamped by the finger cylinder 231. In addition, the performance of the plug connector 200 is greatly reduced after plugging and unplugging multiple display modules 100, so it needs to be replaced regularly, and the finger cylinder 231 is convenient for replacing a new plug connector 200 after opening.

[0045] Specifically, the clamp 23 also includes two clamps 232, which are connected to the two output ends of the finger cylinder 231, and each clamp 232 has a positioning groove for accommodating the side of the plug connector 200. In other words, the two clamps 232 can not only reliably clamp the plug connector 200, but also facilitate replacement of the clamps 232. In addition, the positioning groove can realize the positioning of the plug connector 200 to prevent the plug connector 200 from sliding or falling.

[0046] The following briefly describes the working process of this plug-in assembly:

[0047] First, the support seat 1 is arranged on the inspection station, and the plug-in connector 200 is clamped by the two clamps 232 on the fixture 23. Then, the display module 100 is placed on the assembly plane. Next, according to the position of the assembly plane on the Z axis, the driving mechanism 22 drives the plug-in connector 200 to move to the assembly plane along the Z direction. In addition, according to the coordinate position corresponding to the interface on the display module 100, the three-axis correction mechanism 21 drives the plug-in connector 200 to move in the X-axis direction, move and rotate along the Y-axis direction on the assembly plane, thereby compensating for the position error of the plug-in connector 200 and the interface in the assembly plane, so that the driving mechanism 22 drives the fixture 23 and the plug-in connector 200 to move accurately, and finally completes the automatic plug-in, avoiding the problem that the accuracy of manual plug-in is difficult to control and the efficiency is low. After the plug-in is completed, the display module 100 is lit, and the detection equipment on the detection station performs a display performance test on the display module 100. After the test is completed, the three-axis correction mechanism 21 drives the plug connector 200 to reset and remove the tested display module 100. Similarly, the next display module 100 is transported for testing.

[0048] An embodiment of the utility model provides a testing device, which includes a plug-in structure for a display module as described above.

[0049] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
