[0001] The utility model relates to the technical field of display panel production, and in particular to a display panel testing fixture and a display panel testing device. Background Art

[0002] The air conditioner display panel is the main interface for users to interact with the air conditioner. It not only displays the status information of the air conditioner, but also provides operation options, allowing users to understand and control the operation of the equipment conveniently and intuitively. In the air conditioner production process, the testing of the display panel is a key link to ensure product quality. The existing testing process of the air conditioner display panel is to place the display panel on the test fixture, and connect the connector of the test device to the interface on the display panel, and then turn on the power to see if the display panel is producing the display. However, when testing the existing test device, the tester needs to manually plug and unplug the connector. In the process of frequent plugging and unplugging of the connector by the tester, it is easy to cause the pin core of the plug to be skewed, resulting in damage to the test device and inability to use it normally.

[0003] Therefore, it is necessary to improve the existing air conditioner display panel testing device to overcome the defects of the prior art. Utility Model Content

[0004] In order to overcome the problems existing in the related art, one of the purposes of the present invention is to provide a display panel test fixture, which can automatically unplug the connection line with the display panel during the testing process of the display panel, which helps to reduce the labor intensity of the inspection personnel and improve the testing efficiency; and can avoid the phenomenon that the plug is easily damaged due to frequent manual plugging and unplugging of the connector.

[0005] A display panel test fixture comprises a substrate, wherein the substrate is provided with a test position for placing a display panel;

[0006] A wiring structure and a driving structure are provided below the substrate, a probe seat is provided on the wiring structure, a test probe is provided on the probe seat, and the test probe corresponds to the test position;

[0007] The driving structure is arranged below the wiring structure, the output end of the driving structure is fixedly connected to the wiring structure, and the driving structure drives the wiring structure to move closer to or away from the substrate.

[0008] The driving structure in the fixture of the present application can smoothly push the wiring structure up and down, so that the test probe can accurately contact or leave the test point on the display panel. The driving structure automatically controls the connection and disconnection of the test probe and the display panel, which can reduce the complexity and time cost of manual operation. The automated connection method avoids the need for testers to manually plug and unplug the connection line, significantly reducing the labor intensity of the testers; it can also avoid damage to the plug and interface that may be caused by frequent manual plugging and unplugging of the connector, thereby extending the service life of the equipment.

[0009] In a preferred technical solution of the present invention, N test positions are provided on the substrate, where N is a natural number greater than 1.

[0010] By setting up multiple test positions, testers can place multiple display panels for testing at once, greatly improving test efficiency. In addition, due to the independence of the test positions, the test results of each display panel will not be affected by other display panels, ensuring the accuracy and reliability of the test.

[0011] In a preferred technical solution of the present invention, the wiring structure includes a fixed plate and an adapter plate, a test chip is provided on the fixed plate, the adapter plate is fixed on the fixed plate, the probe seat is provided on the adapter plate, and the test probe on the probe seat is electrically connected to the test chip.

[0012] The test chip is the core component of the testing process, responsible for data processing and transmission. In actual application, the tester simply connects the display panel to the test probes on the adapter board.

[0016] A plurality of the driving structures are provided below the wiring structure, for example, the number of the driving structures is 2-3.

[0017] During the test process, when the display panel needs to be tested, the driver receives a control signal and, through its output terminal, drives the wiring structure upward, allowing the test probe to precisely contact the test point on the display panel. After the test is completed, the driver receives another control signal, driving the wiring structure downward, safely separating the test probe from the display panel.

[0018] In a better technical solution of the present invention, a guide rod is provided on the substrate, a guide block is provided on the wiring structure, a guide hole is provided on the guide block, one end of the guide rod passes through the guide hole, and the axis of the guide rod coincides with the axis of the guide hole.

[0019] As the drive mechanism moves the wiring structure up and down, the guide rods provide guidance and support within the guide holes, preventing the wiring structure from shifting or rotating during movement. This design improves test accuracy and reduces wear caused by unstable wiring structure movement, extending the life of the test fixture.

[0022] An indicator light is provided on one side of each test position.

[0023] Indicator lights play a crucial role in the testing process. When the test probe successfully connects to the display panel and the test begins, the indicator lights up, visually informing the tester that the test position is being tested. If the display panel passes the test, the indicator lights up in a specific color (such as green). If the display panel fails the test, the indicator lights up in another color (such as red), allowing the tester to quickly identify the problem and take appropriate action.

[0024] In a preferred technical solution of the present invention, a locking structure is provided on one side of the receiving groove, and the locking structure includes a second button, a connecting rod and a clamping block;

[0025] The connecting rod is arranged below the base plate, and the base plate is hinged at the middle of the connecting rod.

[0041] The following describes preferred embodiments of the present invention in more detail with reference to the accompanying drawings. Although preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0042] The existing testing process for air conditioner display panels involves placing the display panel on a test fixture, connecting the test device's connector to the display panel's interface, and then powering on the device to verify that the display panel is producing a correct display. However, this existing test device requires the tester to manually plug and unplug the connector during testing. This frequent plugging and unplugging can easily cause the plug's pins to become skewed, resulting in damage to the test device and making it inoperable.

[0043] Based on this, the present application provides a display panel testing fixture.

[0044] Example 1

[0045] like Figure 1-Figure 7 As shown, this embodiment provides a display panel test fixture, which includes a substrate 1, on which a test position for placing a display panel is provided. Below the substrate 1, a wiring structure 2 and a driving structure 3 are provided. The wiring structure 2 is provided with a probe holder 22, and the probe holder 22 is provided with a test probe 21, and the test probe 21 corresponds to the test position. The driving structure 3 is provided below the wiring structure 2, and the output end of the driving structure 3 is fixedly connected to the wiring structure 2. The driving structure 3 drives the wiring structure 2 toward or away from the substrate 1.

[0046] In actual application, the driving structure can smoothly push the wiring structure 2 up and down. The tester only needs to place the display panel on the test position and then start the driving structure 3. The driving structure 3 will drive the wiring structure 2 to move, so that the test probe 21 is inserted into or disconnected from the interface on the display panel, thereby realizing fast and automated testing of the display panel. The connection and disconnection of the test probe 21 and the display panel are automatically controlled by the driving structure 3, which greatly reduces the complexity and time cost of manual operation and can improve test efficiency. The automated connection method avoids the need for testers to manually plug and unplug the connecting wires, reduces the labor intensity of the testers, and can also avoid damage to the plugs and interfaces caused by frequent manual plugging and unplugging of connectors, thereby extending the service life of the equipment.

[0047] In this embodiment, one test position may be provided, and the structure of the test position is adapted to the structure of the display panel to be tested, so the display panel can be placed in the test position for testing.

[0048] It should be noted that the arrangement of the test probes 21 is adapted to the interface of the display panel to be tested, and the test probes 21 can be connected to a tester via a probe holder 22 , so as to test the actual panel using the tester.

[0049] When the test fixture of this embodiment is used to test a display panel, the entire workflow is as follows:

[0050] First, the entire fixture is powered on. After the fixture is powered on, the driving structure 3 is in an extended state, and the driving structure 3 drives the wiring structure 2 to move, so that the wiring structure 2 is tightly attached to the bottom of the substrate 1.

[0051] The display panels are then inserted into the test positions one by one. The test probes 21 are then connected to the display panel product, and testing can begin. The inspector then determines the test results. After the test is complete, the drive structure 3 is activated again, driving the wiring structure 2 downward, separating the test probes 21 from the display panel interface, completing the disconnection process.

[0052] After unplugging the wires, the inspector removes the display panel and places it in different collection boxes according to the test results.

[0053] In this embodiment, a first button 13 is provided on the substrate 1 , and the first button 13 is electrically connected to the wiring structure 2 .

[0054] In this embodiment, the test position includes a receiving groove 15, and a test port 11 is provided at the bottom of the receiving groove 15, and the test port 11 corresponds to the test probe 21; the test port 11 is for the test probe 21 to pass through, so that the test probe 21 can be connected to the display panel through the test port 11, ensuring that the test probe 21 can accurately contact the test point on the display panel. The test port 11 of the present application can be adjusted according to the arrangement of the test probe 21. It should be noted that in another implementation, the test position may not include a receiving groove, and it is only necessary to place the display panel to be tested on the substrate 1.

[0055] An indicator light is provided on one side of each test position.

[0056] In one embodiment, one or more indicator lights may be provided.

[0057] The indicator light plays an important role in the test process. When the test probe 21 is successfully connected to the display panel and the test begins, the indicator light will light up, intuitively informing the tester that the test position is being tested. If the tested display panel passes, the indicator light will light up in a specific color (such as green). If the tested display panel fails, the indicator light will flash in another color (such as red) so that the tester can quickly identify it and take appropriate measures.

[0058] The introduction of indicator lights makes the testing process more intuitive and easier to monitor. Testers can quickly understand the status of each test position through the indicator light, improving work efficiency and operational convenience. If a problem occurs during testing, the flashing or color change of the indicator light quickly guides the tester to the specific test position, facilitating timely troubleshooting and resolution.

[0059] Example 2

[0060] This embodiment is improved on the basis of embodiment 1.

[0061] like Figure 1-Figure 7 As shown, in this embodiment, N test bits are provided on the substrate 1 , where N is a natural number greater than 1.

[0062] It should be noted that the N test positions are independent of each other to ensure that the space between them is optimized and there is no interference. Each test position is equipped with a corresponding test probe 21, which can be independently connected to the respective display panel interface to achieve independent testing of each display panel.

[0063] Compared to traditional single test bays, the multiple test bay design allows for more testing within the same space. Testers can place multiple display panels for testing at once, saving valuable production space and resources and significantly improving testing efficiency. Furthermore, due to the independence of the test bays, the test results of each display panel are not affected by those of other panels, ensuring test accuracy and reliability.

[0064] In a more preferred embodiment, the present application may have 6 test positions, and the 6 test positions correspond to 6 independent test channels, thereby enabling testing of multiple display panels.

[0065] Example 3

[0066] This embodiment is improved on the basis of embodiment 1.

[0067] like Figure 1-Figure 7 As shown, in this embodiment, the wiring structure 2 includes a fixed plate 24 and an adapter plate 23, a test chip 241 is provided on the fixed plate 24, the adapter plate 23 is fixed on the fixed plate 24, the probe seat 22 is provided on the adapter plate 23, and the test probe 21 on the probe seat 22 is electrically connected to the test chip 241.

[0068] The fixed plate 24 serves as the foundation for the wiring structure 2. A test chip 241 is mounted on this plate. This test chip 241 is a core component during the test process, responsible for data processing and transmission. To ensure test accuracy and stability, the test chip 241 is soldered or slotted into the fixed plate 24 to form a stable electrical connection with the adapter plate 23 and other test components.

[0069] The test probes 21 on the adapter board 23 are electrically connected to the test chip 241 through fine wiring, ensuring accurate transmission of the test signal.

[0070] In actual applications, the tester only needs to connect the display panel to be tested with the test probe 21 on the adapter board 23, and the test chip 241 will receive the signal of the display panel through the probe, thereby performing a fast and accurate performance test.

[0071] In actual applications, the test chip 241 can detect the display panel using various parameters, including the operating voltage and current of the display panel; the accuracy, vividness and saturation of the color reproduction of the display panel; measuring the response time of the display panel, that is, the time required for the pixels of the display panel to change from one state to another, so as to evaluate its performance in displaying dynamic images; and testing the resolution of the display panel and other different parameters.

[0072] Furthermore, in this embodiment, a clamping groove 242 is provided on the fixing plate 24 , and a connecting block 231 is provided on the adapter plate 23 . The connecting block 231 and the clamping groove 242 are clamped with each other.

[0073] The snap-fitting groove 242 is designed as a groove with a specific shape and size to ensure a precise fit with the connecting block 231. For example, the cross-section of the snap-fitting groove 242 can be polygonal, circular, or other shapes. The connecting block 231 on the adapter plate 23 is manufactured according to the shape and size of the snap-fitting groove 242 to achieve a stable and precise snap-fit.

[0074] In actual operation, when the adapter plate 23 needs to be connected to the fixed plate 24, the tester simply aligns the connecting block 231 on the adapter plate 23 with the snap-in slot 242 on the fixed plate 24 and gently pushes it in to quickly connect the two. This snap-in connection method enables rapid connection and disassembly between the fixed plate 24 and the adapter plate 23, greatly improving the assembly and disassembly efficiency of the test fixture. The design of the snap-in slot 242 and the connecting block 231 ensures a tight fit between the two, providing a stable connection and ensuring the stability of the electrical connection and the accuracy of data transmission during the test. In addition, the design of the slot and the connecting block 231 is relatively simple, reducing manufacturing difficulty and cost. This connection method also facilitates maintenance. When the adapter plate 23 needs to be replaced or repaired, it can be simply unfastened. This matching method also broadens the scope of application of the fixture of this application. When it is necessary to test an unused display panel, a different adapter plate 23 can be replaced so that the test probes 21 on the adapter plate 23 correspond to the interface of the display panel.

[0075] Example 4

[0076] This embodiment describes the driving structure 3 in detail.

[0077] like Figure 1-Figure 7 As shown, in this embodiment, the driving structure 3 includes a mounting seat 31 and a driving device 32. The mounting seat 31 is arranged below the wiring structure 2. The driving device 32 is fixed in the mounting seat 31. The output end of the driving device 32 is fixedly connected to the wiring structure 2.

[0078] Two to three driving structures 3 are provided below the wiring structure 2. In a more preferred embodiment, two driving structures 3 are provided, and the two driving structures 3 are connected to both ends of the fixing plate 24 respectively.

[0079] The mounting base 31 is used to ensure the stability of the installation of the driving device 32. The driving device 32 of the present application can be a cylinder or a push rod motor, and the driving device 32 is used to achieve the linear motion of the wiring structure 2.

[0080] During the test process, when the display panel needs to be tested, the drive device 32 receives a control signal and, through its output terminal, drives the wiring structure 2 upward, ensuring that the test probe 21 precisely contacts the test point on the display panel. After the test is complete, the drive device 32 receives another control signal and drives the wiring structure 2 downward, safely separating the test probe 21 from the display panel.

[0081] Furthermore, in this embodiment, a guide rod 12 is provided on the substrate 1, a guide block 4 is provided on the wiring structure 2, a guide hole 41 is provided on the guide block 4, one end of the guide rod 12 passes through the guide hole 41, and the axis of the guide rod 12 coincides with the axis of the guide hole 41, thereby ensuring that the wiring structure 2 always maintains a stable and accurate path during the up and down movement.

[0082] When the drive structure 3 moves the wiring structure 2 up and down, the guide rod 12 provides guidance and support within the guide hole 41, preventing the wiring structure 2 from shifting or rotating during movement. This design improves test accuracy and reduces wear caused by unstable movement of the wiring structure 2, extending the life of the test fixture.

[0083] In a more preferred embodiment, a plurality of guide rods 12 may be provided, and the number of guide blocks 4 corresponds to the number of guide rods 12 , so as to provide a good guiding effect on the movement of the wiring structure 2 .

[0084] Example 5

[0085] This embodiment is improved on the basis of embodiment 4.

[0086] like Figure 1-Figure 7 As shown, in this embodiment, a locking structure is provided on one side of the receiving groove 15 , and the locking structure is used to ensure the stability and safety of the display panel during the test process.

[0087] Specifically, the locking structure includes a second button 14, a connecting rod 17 and a clamping block 18;

[0088] The connecting rod 17 is disposed below the base plate 1, and the base plate 1 is hinged at the middle of the connecting rod 17. The connecting rod 17 has a first end 171 and a second end 172 that are oppositely disposed, and the first end 171 extends into the receiving groove 15. The second button 14 is disposed on the base plate 1 and is connected to the second end 172 of the connecting rod 17 via a first elastic rod 16.

[0089] The latching block 18 is disposed on a sidewall of the receiving slot 15, with one side of the latching block 18 extending into the receiving slot 15. The latching block 18 is connected to the connecting rod 17 via a second elastic rod 19. The axis of the second elastic rod 19 forms an angle α with the sidewall of the receiving slot 15, where 15° < α < 45°. This angle α enables the second elastic rod 19 to exert a sufficient force on the latching block 18. After being pushed out of the receiving slot 15, the latching block 18 can be reset under the action of the second elastic rod 19, thereby limiting the position of the display panel.

[0090] The first elastic rod 16 and the second elastic rod 19 of the present application are both made of a retractable elastic material. More specifically, the first elastic rod 16 and the second elastic rod 19 can both be springs.

[0091] The base plate 1 is hinged in the middle of the connecting rod 17, and the hinge is the fulcrum of the connecting rod 17. The fulcrum makes the connecting rod 17 form a seesaw structure. When the first end 171 of the connecting rod 17 is pressed down, the second end 172 of the connecting rod 17 will tilt up; when the second end 172 of the connecting rod 17 is pressed down, the first end 171 of the connecting rod 17 will tilt up.

[0092] A second button 14 is provided on the base plate 1 for easy operation by the tester. The second button 14 is connected to the second end 172 of the connecting rod 17 via the first elastic rod 16. When the tester presses the second button 14, the first elastic rod 16 drives the second end 172 of the connecting rod 17 downward, causing the first end 171 of the connecting rod 17 to tilt upward.

[0093] In its natural state, one side of the card block 18 protrudes from the receiving slot 15. When the display panel is inserted into the receiving slot 15, it pushes the card block 18 from the receiving slot 15 toward the outside of the receiving slot 15. Due to the presence of the second elastic rod 19, the card block 18 can move under the push of the display panel. After the display panel is inserted into the receiving slot 15, the card block 18 is reset under the action of the second elastic rod 19 and returns to the receiving slot 15, forming a limit for the display panel to ensure stable testing. After the test is completed, the inspector presses the second button 14, causing the second end 172 of the connecting rod 17 to move downward, causing the first end 171 of the connecting rod 17 to tilt upward. The tilting of the connecting rod 17 drives the card block 18 to move from the receiving slot 15 toward the outside of the receiving slot 15. At this time, the display panel is in the unlocked state. At the same time, the tilting of the first end 171 causes the display panel to protrude, making it easier for the inspector to remove the display panel.

[0094] The locking structure design of the present invention can ensure the stability and safety of the display panel during the test process, thereby improving the accuracy and reliability of the test. The tester can fix and unlock the display panel with a simple button operation, greatly improving work efficiency.

[0095] It should be noted that a locking structure is provided on one side of each receiving slot 15 .

[0096] Example 6

[0097] like Figure 1-Figure 7 As shown, the second purpose of the present invention is to provide a display panel testing device, which includes the test fixture and a tester as described above, and the tester is electrically connected to the wiring structure 2.

[0098] More specifically, the tester includes a processor with high-precision data acquisition and analysis capabilities, enabling accurate evaluation of the display panel's performance and status. During actual testing, the tester uses wiring structure 2 to obtain various display panel parameters, such as voltage, current, and signal response time, to comprehensively assess the panel's operating status.

[0099] The testing device claimed in this application improves the testing efficiency, accuracy and reliability of display panels by integrating automated test fixtures and high-precision testers, while reducing the risks of human error and equipment damage, providing a comprehensive and efficient solution for the testing and evaluation of display panels.

[0100] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures.
