The elastic coefficient of the telescopic spring 56 can be set according to the requirements. A vertical plate 57 is fixedly installed at the bottom of the lifting connecting plate 52. A trapezoidal plate 58 is fixedly installed on the front side of the vertical plate 57. The bottom of the rear strip plate 42 is attached to the top of the trapezoidal plate 58.

[0032] The pressing mechanism 5 applies pressure to the display screen through the pressure plate 53 at the bottom of the lifting connecting plate 52, simulating the pressing operation of the user during use. The extension spring 56 provides the restoring force when the vertical rod 54 moves upward.

[0033] The light-shielding assembly 8 includes a bracket 81. Two brackets 81 are fixedly installed on the bottom of the top plate 7. A plate 82 extending to the bottom of the bracket 81 is slidably installed on the inner side of the bracket 81. The bracket 81 is used to install the plate 82. A side plate 83 is fixedly installed on the bottom of the plate 82. A main board 84 is fixedly installed between the right sides of the two side plates 83. A handle 85 is fixedly installed on the right side of the main board 84.

[0034] By sliding the card plate 82 and side plate 83, as well as the handle 85 on the main board 84, external light is blocked to ensure the accuracy of the test. The main board 84 can be pulled to the right by the handle 85, which moves the side plate 83 and card plate 82, disconnecting the card plate 82 from the card holder 81, making it easy to disassemble the light-shielding component 8 and convenient for operators to use.

[0035] The camera mechanism 9 includes a servo motor 91. The servo motor 91 is fixedly installed on the top of the top plate 7. The servo motor 91 is electrically connected to an external power supply and is controlled by an external program. The output shaft of the servo motor 91 can rotate in both directions. A rotating rod 92 extending to the bottom of the top plate 7 is fixedly installed at the output shaft of the servo motor 91. A circular hole adapted to the rotating rod 92 is opened inside the top plate 7. A swing plate 93 is fixedly installed at the bottom of the rotating rod 92. A fixed frame 94 is fixedly installed on the right side of the mounting plate 6. A movable frame 95 extending to the right side of the fixed frame 94 is slidably installed on the inner side of the fixed frame 94. The fixed frame 94 ensures the stability of the movable frame 95 when moving left and right. A circular rod 96 extending to the inner side of the movable frame 95 is fixedly installed at the bottom of the swing plate 93. A groove adapted to the movement trajectory of the circular rod 96 is opened at the top of the movable frame 95. A camera 97 is fixedly installed at the bottom of the movable frame 95. The camera 97 is connected to a mobile power supply cable.

[0036] During use, the mobile phone display screen to be tested is placed on the right rectangular plate 41 and clamped and fixed by the elastic action of the pressing mechanism 5, the sliding plate 44, the telescopic rod 46, and the fixing spring 47. When the right rectangular plate 41 drives the strip 42 to rotate until it contacts the trapezoidal block 58, it continues to move, causing the strip 42 to press the trapezoidal block 58 down. The trapezoidal block 58, supported by the lifting connecting plate 52, pulls the vertical plate 57, causing the pressure plate 53 to move down. The pressure plate 53 presses and pushes the mobile phone display screen into the four sliding plates 44. After the mobile phone display screen is fixed, the light shielding component 8 is installed and adjusted to block the external light. The electric push rod 10 is started, and the power plug 12 is inserted into the power interface of the display screen to supply power to the display screen. The rotating motor 32 is started, driving the display screen to rotate below the top plate 7. At the same time, the camera mechanism 9 is started to take a full picture of the display screen and record the test results. After the test is completed, the lighting effect and display quality of the display screen, as well as its performance after the pressing test, are analyzed by observing the images captured by the camera mechanism 9. Based on the test results, the quality of the display screen is evaluated and improved.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] In summary, this mobile phone display screen lighting test device, by setting up a rotating mechanism 3 and a mounting mechanism 4, facilitates the simultaneous testing of multiple mobile phone displays. The mobile phone display screen to be processed is placed inside the right rectangular plate 41. The rotating motor 32 is started, and its output shaft drives the mounting plate 33 and the four rectangular plates 41 to rotate, thereby rotating the right-side mobile phone display screen to below the right-angle plate 51. The pressing mechanism 5 installs the mobile phone display screen inside the rectangular groove 43. After fixing, the mounting plate 33 continues to rotate, causing the mobile phone display screen to rotate to below the top plate 7 for subsequent lighting tests. After testing, the mobile phone display screen rotates to the front and is pushed out from bottom to top. The tested mobile phone display screen can then be placed into a new... By repeating the above operations on the mobile phone display screen, the purpose of testing multiple mobile phone display screens simultaneously can be achieved. By setting up the camera mechanism 9, different detection points can be captured. The servo motor 91 drives the rotating rod 92 and the swing plate 93 to rotate through its output shaft. The round rod 96 at the bottom of the swing plate 93 pushes the moving frame 95 to slide within the fixed frame 94, thereby moving the camera 97 to capture a comprehensive image of the mobile phone display screen, recording its lighting effect and display quality. This achieves the purpose of capturing images of different detection points, solving the problem that only one mobile phone display screen can be tested during the testing process, resulting in a long testing time and the inability to capture test results at different detection points, leading to poor testing accuracy.
