[0022] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0023] This application proposes a fixture for automatically testing the screen display of a display module. Please refer to Figure 1 and Figure 2 , which includes: a flip cover 10, a test box 11, an elastic member 31, a pressing block 32, a pressing head 20, and a plurality of probes 30. A main board 12 is arranged in the test box 11, and a test program is arranged on the main board 12. The test program can control the display module electrically connected thereto to automatically run and switch the screen. A connection board electrically connected to the main board 12 is arranged on the flip cover 10, and the display module is electrically connected to the main board 12 through the connection board, playing a role of transfer. The pressing block 32 is arranged above the flip cover 10, and a probe hole matching the probe 30 is formed on the pressing block 32, and the probe 30 is arranged on the probe hole. The flip cover 10 elastically holds the pressing block 32 through the elastic member 31. When the pressing head 20 presses the pressing block 32 and the FPC of the display module, the probe 30 is ejected from the probe hole to be electrically connected to the FPC, so that a fixture for automatically testing the screen display of a display module can automatically control the power on / off and screen switching of the display module, check whether the display module can work normally, without manually using buttons to switch the screen, reducing the work intensity of the staff and improving the test efficiency. Preferably, the elastic member 31 is a spring.

[0024] It should be noted that a control program required for testing is burned in the main board 12. A fixture for automatically testing the screen display of a display module can automatically control the power on / off and screen switching of the display module and check whether the display module can work normally. Just place the display module manually.

[0025] In one embodiment, the flip cover 10 is foldably covered on the test box 11, so that the test box 11 can be easily opened. The flip cover 10 is connected to the test box 11 to prevent the flip cover 10 from being lost. A fixing member 23 is arranged on the flip cover 10, so that after the pressing head 20 presses the FPC, the pressing head 20 can be stuck. When it is necessary to replace the display module to be tested, the fixing member 23 can release the pressing head 20.

[0026] Furthermore, please refer to Figure 2 again. The pressing head 20 includes a folding plate 21 and a holding column 22. The holding column 22 is arranged on the bottom surface of the folding plate 21. The holding column 22 can hold the pressing block 32, so that one end of the folding plate 21 is foldably connected to the flip cover 10, reducing the difficulty of pressing, without repeatedly aligning and pressing the pressing block 32, and having a low fixing difficulty.

[0027] Still further, the probes 30 are arranged in a straight line, avoiding the failure connection of some probes 30 with the FPC, thereby causing test failures of the display module.

[0028] In one embodiment, the number of elastic members 31 is two, and the elastic members 31 are respectively arranged at both ends of the bottom of the pressing block 32. When the holding block presses the surface of the pressing block 32, the elastic members 31 hold the pressing block 32 firmly, preventing the pressing block 32 from shaking left and right and coming into contact with the flip cover 10, thus avoiding the generation of abnormal noise. Moreover, the elastic balance at both ends of the pressing block 32 is good, and the stability is better.

[0029] Furthermore, an FPC alignment groove 13 is provided on the top surface of the flip cover 10, enabling the FPC to be accurately placed on the flip cover 10 and electrically connected to each probe 30 one by one, ensuring that the pins correspond to the probes 30 one by one.

[0030] Please refer to again Figure 2 , a fixture for automatically testing the display of a display module screen further includes a power switch 40. The power switch 40 is used to control the power-on of the main board 12, so that when the fixture for automatically testing the display of a display module screen is not in use, it ensures that the fixture is in a shutdown state, avoiding malfunctions of the fixture for automatically testing the display of a display module screen and causing safety accidents. Further, the power switch 40 is arranged on the test box 11, and the power switch 40 is arranged on the outside of the test box 11 for the convenience of the staff to toggle the power switch 40. In addition, the fixture for automatically testing the display of a display module screen further includes an induction switch 50, and the induction switch 50 is arranged on the upper surface of the flip cover 10. When the pressing head 20 presses down and triggers the induction switch 50, the induction switch 50 is used to determine whether the display module is connected. When the induction switch 50 detects that the display module is connected, it powers on the fixture for automatically testing the display of a display module screen. In other states, the fixture for automatically testing the display of a display module screen is in a non-powered state, avoiding the staff from contacting the probes 30 and causing electric shock accidents to ensure the safety of the staff.

[0031] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation of the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
