[0027] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0028] The present invention provides an automated test fixture comprising a base, a position detection component, and a plug-in / plug-out component. The base is used to secure the system end of a product to be tested. The plug-in / plug-out operation is performed on the base. The position detection component acquires position change information of the display end. When the position of the display end changes, indicating that the display end has been plugged in or unplugged, the image acquisition structure in the plug-in / plug-out component acquires image information of the display end's display screen. Based on this image information, it is determined whether the operating system has completed the switch, thereby completing a test. Repeating this test process completes the automated test operation of a product to be tested.

[0029] The following describes in detail the various structures of the automated test fixture provided by the embodiment of the present invention, as well as the positional relationship and connection relationship between the various structures, in conjunction with the accompanying drawings.

[0030] like Figures 1 to 4 As shown, the base 10 includes a bearing surface 11 and a bracket 12. The bearing surface 11 is used to connect the product 40 to be tested. The bracket 12 has a set height and is arranged on the bearing surface 11. As shown in the figure, the base 10 has a set height and is a workbench. Its upper surface is the bearing surface 11, and the bracket 12 is arranged at the edge of the bearing surface 11.

[0031] In this embodiment of the present invention, the base 10 further includes a limiting structure 13 located outside the support surface 11. The limiting structure 13 is used to secure the side and surface of the system terminal. The limiting structure 13 restricts the position of the system terminal, thereby firmly mounting the system terminal on the support surface 11. The limiting structure 13 limits the position of the system terminal in the X and Y directions relative to the support surface 11, as well as in the Z direction perpendicular to the support surface 11.

[0032] For example, the side end of the system end includes a limiting plate, which is in contact with the side end of the system end. Multiple limiting plates cooperate to limit the position of the system end in the X and Y directions. For example, the limiting plate can be set in a sliding manner, with a sliding plate set at the bottom end of the limiting plate, and a strip hole is set on the sliding plate. A screw is passed through the strip hole, and a compression nut is screwed on the screw. After the limiting plate is moved into place, the compression nut is used to fix the sliding plate.

[0033] For example, a pressure plate can be installed at the edge of the system end surface. The pressure plate is rotatably connected to a stud located at the side of the system end. When the surface of the system end needs to be compressed, the pressure plate can be rotated to the surface of the system end. For example, a compression nut can be installed on the stud, and the compression nut can be used to tighten the pressure plate to fix the position of the pressure plate. For example, the stud can be configured to be movable to accommodate system ends of different sizes.

[0034] In an embodiment of the present invention, the bracket 12 includes two vertical frames 121 and a horizontal frame 122, one end of the two vertical frames 121 is respectively vertically connected to the bearing surface 11, and the two ends of the horizontal frame 122 are respectively connected to the other ends of the two vertical frames 121; the position detection component 20 is arranged on the vertical frame 121, and the plug-in component 30 is arranged on the horizontal frame 122.

[0035] The two vertical frames 121 are arranged in parallel and at intervals and have a certain height, so that the plug-in assembly 30 can be placed above the product to be tested 40 to complete the plug-in and pull-out operations on the display terminal.

[0036] Continue to refer Figures 1 to 4 As shown, in the embodiment of the present invention, the position detection component 20 is arranged on the bracket 12 and is used to obtain the movement information of the product to be tested 40; based on the obtained movement information, it can be determined whether the position of the product to be tested 40 has changed, that is, whether it has been unplugged or plugged back in. When this change occurs, the display screen of the display end will also change. By obtaining the image information of the display screen, it can be further determined whether the operating system has completed the switch.

[0037] For example, the position detection component includes an acoustic and optical sensor, which is arranged toward the direction of the product 40 to be tested; the clamping structure 31 is used to drive the display end to move between the separation position and the connection position. When the display end is in the separation position, the acoustic and optical sensor collects a first position signal, and when the display end is in the connection position, the acoustic and optical sensor collects a second position signal.

[0038] For example, when the display terminal is in the separated position, the acoustic and optical sensor detects the display terminal and collects a first position signal. When the display terminal is in the connected position, the acoustic and optical sensor does not detect the display terminal and collects a second position signal. In other words, as the display terminal moves, the display terminal triggers or de-activates the acoustic and optical sensor, thereby determining the position change of the display terminal.

[0039] Continue to refer Figures 1 to 4 As shown, in an embodiment of the present invention, the plug-in assembly 30 includes a clamping structure 31 and an image acquisition structure 32. The clamping structure 31 is used to clamp the display end of the product to be tested 40 and drive the display end to be separated from or connected to the system end of the product to be tested 40. When the display end is connected to or separated from the system end, the display end switches the display screen, and the image acquisition structure 32 is used to obtain image information of the display screen.

[0040] The acquired image information is sent to the computer. By comparing the acquired image information with the preset image information, it can be determined whether the image at that time is consistent. If the image is consistent, the switching of the display screen is determined, that is, the switching of the operating system is completed. If it is inconsistent, it means that the operating system has not been switched, and an alarm can be issued.

[0041] For example, the plug-in assembly 30 also includes a lifting structure 33, which includes a slide rail 331, a slider 332 and a driving member. The driving member is connected to the slider 332 and is used to drive the slider 332 to slide on the slide rail 331; the slide rail 331 is connected to the horizontal frame 122, and the clamping structure 31 and the image acquisition structure 32 are arranged on the slider 332.

[0042] For example, the drive member includes a drive motor, the output shaft of which is connected to a lead screw, which is threadedly connected to the slider 332. The forward or reverse rotation of the drive motor controls the raising and lowering of the slider 332. When the slider 332 is raised or lowered, the clamping structure 31 and the image acquisition structure 32 move synchronously.

[0043] In this embodiment of the present invention, the clamping structure 31 includes a clamping frame 311 and a clamp 312. One end of the clamping frame 311 is connected to a slider 332, and the other end is connected to the outer wall of the clamp 312. The clamp 312 is used to clamp the display terminal. After the clamp 312 clamps the display terminal, it moves with the slider 332 to complete the insertion and removal of the display terminal.

[0044] For example, the clamp 312 includes an inverted U-shaped groove 3121 and a locking member 3122; the other end of the clamping frame 311 is connected to the outer wall of the horizontal plate of the inverted U-shaped groove 3121; the locking member 3122 includes a push plate 31221 and a screw 31222. The push plate 31221 is located in the inverted U-shaped groove 3121, and one end of the screw 31222 is connected to the push plate 31221, while the other end extends through a vertical plate of the inverted U-shaped groove 3121, and the screw 31222 is threadedly connected to the vertical plate. There is a gap between the push plate 31221 and the other vertical plate of the inverted U-shaped groove 3121, and the end of the display terminal is placed in this gap. When in use, the position of the push plate 31221 is adjusted by screwing the screw 31222, thereby achieving a clamping operation on the display terminal. For example, a rubber layer is provided on the side of the push plate 31221 facing the display terminal to prevent scratching the display terminal.

[0045] For example, a knob is provided at the other end of the screw rod 31222 , and the screw rod 31222 is rotated using the knob.

[0046] In this embodiment of the present invention, the image acquisition structure 32 includes a support rod 321 and a camera 322. One end of the support rod 321 is connected to the camera 322, and the other end is connected to the slider 332. The support rod 321 has a certain length, extending the camera 322 to the side of the display screen of the display terminal, and the height of the camera 322 is lower than the height of the clamp 312.

[0047] For example, support rod 321 includes multiple adjustment rods, each connected by a universal joint. These rods and the universal joint are used to adjust the position of camera 322 at multiple angles. This combination provides a higher degree of freedom, allowing camera 322 to be adjusted to multiple positions to meet image acquisition requirements at various locations.

[0048] When using an automated test fixture provided by the present invention, the system end of the product to be tested 40 is fixed on the base 10, the plug-in component 30 is connected to the display end, and the display end is pulled to separate the display end from the system end. During the separation process, the position detection component 20 is used to obtain the position change information of the display end, and the image acquisition structure 32 is controlled according to the position change information to obtain the image information of the display screen; wherein, the display screen after the two operating systems are switched is pre-set, and when the current image information obtained by the acquisition structure matches the image information of the pre-set operating system, it is confirmed that the operating system switching is completed. The technical solution of the present invention adopts an automated operation method for testing, which can effectively improve the work efficiency of the test, and has less manual intervention, which can reduce the manual work intensity. In addition, mechanized testing is more accurate than manual testing, and the test results are more accurate.
