[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0023] A small-sized universal screen manual pressing and lighting test machine includes a body 6, a test platform 4, a test structure 11, and a fixed cover plate 12. The test structure 11 is set on the test platform 4, and there are two test structures 11 on the test platform 4. The fixed cover plate 12 is set on the test platform 4, and the test structure 11 is between the test platform 4 and the fixed cover plate 12. The test platform 4 is set on the body 6.

[0024] During testing, open the fixing cover 12, place the display screen to be tested on the test platform 4, and place the connecting strap of the display screen on the test structure 11. Close the fixing cover 12, and the display screen is fixed between the test platform 4 and the fixing cover 12. The connecting strap of the display screen is pressed between the test structure 11 and the fixing cover 12. Power is applied to the test structure 11, and the connecting strap is also powered, and the display screen lights up.

[0025] A fixing plate is fixedly connected to the side of the test bench 4 near the body 6. Two fixing plates are mirror-image arranged on the test bench 4. The body 6 has a fixing slot 14 that matches the fixing plate. The fixing plate is inserted into the fixing slot 14, at which point the test bench 4 is pre-positioned on the body 6. The end of the fixing plate away from the test bench 4 is tapered to facilitate insertion into the fixing slot 14.

[0026] The test bench 4 is equipped with a mounting plate 9, which is connected to the body 6. A fixing rod 10 is threaded onto the mounting plate 9 and is threaded onto the test bench 4. A positioning rod 8 is threaded onto the mounting plate 9 and is threaded onto the body 6. Through the mounting plate 9, the fixing rod 10, and the positioning rod 8, the test bench 4 is fixed to the body 6.

[0027] Simultaneously, the positioning rod 8, fixing rod 10, and mounting plate 9 can be disassembled from the machine body 6 and the test platform 4, allowing the test platform 4 to be detached from the machine body 6 for easy replacement and convenient screen lighting tests for displays of different sizes and models. The screen lighting test machine of this invention is suitable for screen lighting tests of small-sized displays.

[0028] The test platform 4 is tilted on the body 6 to facilitate the installation and removal of the display screen for screen lighting tests. Multiple auxiliary holes 7 are provided on the body 6 to facilitate the movement of the body 6.

[0029] A limiting plate 5 is fixedly connected to the body 6. The limiting plate 5 abuts against the test table 4. Since the test table 4 is set at an angle on the body 6, the limiting plate 5 plays a limiting role on the test table 4, and at the same time provides an additional support force for the test table 4, reducing the pressure on the fixed plate.

[0030] A limiting block is fixedly connected to the limiting plate 5, and a limiting groove 13 is opened on the test platform 4. The limiting block is inserted into the limiting groove 13. Before the fixing rod 10 and the positioning rod 8 are used to fix the test platform 4 and the machine body 6, the limiting block and the fixing plate can further increase the stability of the test platform 4 on the machine body 6, which makes it convenient to fix the test platform 4 on the machine body 6 using the mounting plate 9, the fixing rod 10 and the positioning rod 8.

[0031] A first positioning plate 1 is fixedly installed on the fixed cover plate 12, and the number of first positioning plates 1 is the same as the number of test structures 11. An insertion slot 2 is provided on the first positioning plate 1, and two insertion slots 2 are mirror-image arranged on the first positioning plate 1. An insertion rod 3 is fixedly installed on the test platform 4, and the number of insertion rods 3 is the same as the number of insertion slots 2. The insertion rods 3 are inserted into the insertion slots 2.

[0032] The test structure 11 is located between the first positioning plate 1 and the test platform 4. Through the insertion rod 3 and the insertion slot 2, the fixed cover plate 12 can be more stably closed on the test platform 4. When the fixed cover plate 12 is closed, it can better press the connecting strip of the display screen onto the test structure 11, resulting in better test performance.

[0033] The implementation principle of this embodiment is as follows: When it is necessary to perform screen lighting tests on different displays, the fixing rod 10 and the positioning plate are removed from the test platform 4 and the body 6, the mounting plate 9 is removed, the two ends of the test platform 4 are grasped, the test platform 4 is pulled upward, the fixing plate is separated from the fixing groove 14, the limiting block is separated from the limiting groove 13, and the test platform 4 is removed from the body 6.

[0034] Select a suitable test platform 4 and reinstall it on the body 6, so that the fixing plate is inserted into the fixing groove 14 and the limiting block is inserted into the limiting groove 13. At this time, the test platform 4 is pre-positioned on the body 6. Connect the mounting plate 9 to the test platform 4 and the body 6 respectively, and then thread the fixing rod 10 and the positioning rod 8 to the test platform 4 and the body 6 respectively. In this way, the test platform 4 can be replaced according to the model and size of the display screen, so that the test platform 4 of the screen lighting test machine can be replaced.
