The bottom end of the third rotating disk 357 is rotatably connected to the detection platform 1, a sliding groove 358 is provided on the outer side of the rotating shaft of the third rotating disk 357, and the protrusion 359 is slidably connected to the inside of the sliding groove 358. A second rotating disk 353 is provided on the side of the top plate 35 close to the first rotating disk 23, and the bottom end of the second rotating disk 353 is rotatably connected to the detection platform 1. A torsion spring 354 is fixed to the bottom end of the second rotating disk 353, and the bottom end of the torsion spring 354 is fixedly connected to the support disk 3. A rotating rod 355 is fixed to the top end of the second rotating disk 353, and a limiting frame 356 is provided above the rotating rod 355. The limiting frame 356 is fixedly connected to the support disk 3, and a transmission rod 352 is provided between the second rotating disk 353 and the third rotating disk 357;

[0034] When the display screen module is produced, it is necessary to perform a lighting test on it to detect whether the display screen module is qualified. During the test, the display screen module is placed on the top of the placement frame 2, and the placement frame 2 moves above the support plate 3. At this time, the placement frame 2 drives the display screen module to move below the pressure plate 31. Under the push of the pressure plate 31, the display screen module can be pressed into the inside of the placement frame 2. At this time, the operation of fixing the display screen module inside the placement frame 2 can be completed. Then the placement frame 2 continues to move above the support plate 3. At this time, the placement frame 2 equipped with the display screen module moves to the bottom of the camera 34. At this time, the power plug 341 is connected to the connection port of the display screen module. Then the display screen module is powered on and its display content is controlled by the control device of the detection platform 1. During the display process, the camera 3 4 takes a picture of the content displayed on the display screen module. By comparing the photographed patterns, the lighting status of the current display screen can be known, which is more accurate than observation by human eyes. After the detection, the placement frame 2 continues to move. At this time, the placement frame 2 moves to the top of the top plate 35. At this time, the top plate 35 extends from the inside of the second guide groove 351. The top plate 35 pushes out the display screen module inside the placement frame 2 through the through hole 211. Then the placement frame 2 continues to move, so that the placement frame 2 can drive the display screen module after the detection back to the original position. At this time, the staff will remove it and put in the display screen module that needs to be detected later. During the rotation of the rotating frame 22, the staff can put multiple display screen modules into other placement frames 2, which can reduce the time of loading and unloading the display screen modules and improve the efficiency of detection.

[0035] like Figures 1 to 4 As shown, the outer end of the rotating frame 22 is fixedly connected to the placement frame 2;

[0036] When the rotating frame 22 drives the placement frame 2 to rotate, the first motor 24 is started to drive the rotating frame 2 to rotate. At this time, the rotating frame 22 can drive the placement frame 2 to move, so that the placement frame 2 can automatically move above the supporting plate 3, which is convenient for switching the position of the placement frame 2.

[0037] like Figures 1 to 3 As shown, a plurality of limit springs 21 are fixed at equal intervals inside the placement frame 2, and a positioning hole for positioning the connection seat is opened at the bottom end of the placement frame 2;

[0038] When placing the display screen module on top of the placement frame 2, align the connection port of the display screen module with the positioning hole of the placement frame 2. When the pressure plate 31 presses down the display screen module, the limiting spring piece 21 can be deformed. When the display screen module moves to the bottom end of the placement frame 2, the limiting spring piece 21 can fix the outside of the display screen module, so that it can be in a stable state during subsequent testing.

[0039] like Figures 1 to 5 As shown, a sponge block is fixed to the bottom end of the pressure plate 31;

[0040] When the cam 314 is lifted up, the cam 315 is lifted up and the cam 316 is in the process of being lifted up.

[0041] like Figures 1 to 5 As shown, the outer sleeve of the lifting column 311 is provided with a first spring 312, the top end of the first spring 312 is fixedly connected to the lifting column 311, and the bottom end of the first spring 312 is fixedly connected to the top end of the support frame 313;

[0042] When the lifting column 311 moves downward, the first spring 312 is squeezed and compressed. When the rotating frame 22 drives the inclined block 221 to rotate and separate from the push rod 315, the push rod 315 loses its supporting force. At this time, the elastic force of the first spring 312 pushes the lifting column 311 upward, and the lifting column 311 drives the pressure plate 31 to return to its original position. At the same time, the lifting column 311 lifts the flip rod 314 to restore the flip rod 314 to its original position. The distance between the end of the flip rod 314 away from the push rod 315 and the support rod is longer than the distance between the end of the flip rod 314 close to the push rod 315 and the support rod. Therefore, the weight of the end away from the push rod 315 is higher, which can press the flip rod 314 downward to make it close to the top of the lifting column 311.

[0043] like Figures 1 to 7 As shown, a support plate 33 is fixed to one side of the top of the support plate 3 near the camera 34, a lifting plate 32 is arranged on one side of the support plate 33, the camera 34 is arranged below the lifting plate 32, a third motor 331 is installed in the middle of the top of the support plate 33, a lifting slot 333 is provided inside the top of the support plate 33 near the third motor 331, a threaded rod 332 is fixed to the end of the rotating shaft of the third motor 331, the threaded rod 332 is rotatably connected to the inside of the lifting slot 333, a lifting block 321 is slidably connected to the inside of the lifting slot 333, and one side of the lifting block 321 is fixedly connected to the lifting plate 32;

[0044] When the rotating frame 22 drives the placement frame 2 to rotate to the bottom of the camera 34, when the camera 34 needs to be moved above the display screen module, the third motor 331 is started to drive the threaded rod 332 to rotate. At this time, the threaded rod 332 drives the lifting block 321 to move inside the lifting slot 333, and the lifting block 321 drives the lifting plate 32 to move downward. At this time, the lifting plate 32 can drive the camera 34 to be close to the display screen module, which can make it easier to test the display screen module.

[0045] like Figures 1 to 7 As shown, a second spring 335 is fixed below one end of the lifting plate 334 away from the push block 336, and the bottom end of the second spring 335 is fixedly connected to the detection platform 1;

[0046] When testing the display screen module, it is necessary to power on the display screen module. At this time, the bottom end of the lifting block 321 will contact the top of the lifting plate 334 when the lifting block 321 moves downward. At this time, the lifting plate 334 is pressed to make the other end tilt up. At this time, the lifting plate 334 pushes the push block 336 to rise upward in the movable hole. At this time, the push block 336 drives the power plug 341 to be inserted into the connection port of the display screen module. At this time, the display of the display screen module can be controlled. When the test is completed, the third motor 331 rotates in the opposite direction to drive the lifting block 321 to drive the camera 34 upward to rise. At this time, the second spring 335 pushes the lifting plate 334 to return to its original position. At this time, the push block 336 can pull the power plug 341 to separate from the connection port of the display screen module.

[0047] like Figures 6 to 8 As shown, a first guide groove 323 is provided at the top of the lifting plate 32, a slider 326 is fixed at the top of the camera 34, a sliding column is fixed at the top of the slider 326, and the sliding column is slidably connected to the first guide groove 323, a second motor 324 is fixed at the top of the lifting plate 32, a rotating frame 325 is fixed at the end of the rotating shaft of the second motor 324, and a light shield 322 is fixed at the bottom of the lifting plate 32;

[0048] When the lifting plate 32 moves downward, the shading cover 322 moves downward with the lifting plate 32. When the lifting plate 32 stops moving, the shading cover 322 can cover the top of the display screen module. At this time, the shading cover 322 can block the light during the test to prevent external light from affecting the test results. During the test, the content displayed on the display screen can be photographed by the camera 34 to compare the display conditions. During the shooting process, the second motor 324 is started to drive the rotating frame 325 to rotate. At this time, the rotating frame 325 pushes the sliding column at the top of the slider 326 to move, and the sliding column slides inside the first guide groove 323. The sliding column can drive the slider 326 to move. The slider 326 drives the camera 34 to move to different positions for shooting. At this time, the camera 34 can capture images at multiple positions. At this time, the test result will be more accurate. When the sliding column moves to one end inside the first guide groove 323, a test is completed. During the next test, the second motor 324 drives the rotating frame 325 to rotate in the opposite direction to drive the sliding column to move in the opposite direction.

[0049] like Figure 8 As shown, a first slide bar 327 runs through the interior of the slider 326, and second slide bars 328 are fixed on both sides of the interior of the light shield 322. Both ends of the first slide bar 327 are slidably connected to the two second slide bars 328 through sliding sleeves;

[0050] During the movement of the slider 326, in order to prevent the slider 326 from rotating and driving the camera 34, a first slide bar 327 is set to limit the slider 326. When the slider 326 moves horizontally, the slider 326 slides on the outside of the first slide bar 327. When the slider 326 moves longitudinally, it will drive the first slide bar 327 to slide between the second slide bar 328. During the movement, the direction of the camera 34 can be ensured not to change, and the direction of the captured image is consistent, which is more convenient for testing.

[0051] like Figures 1 to 10 As shown, gears are fixed at both ends of the transmission rod 352, and the gears are respectively meshed and connected with the second rotating disk 353 and the third rotating disk 357;

[0052] When the rotating frame 22 rotates, it will drive the first rotating disk 23 to rotate. At this time, the first rotating disk 23 drives the rotating block 231 to move. When the rotating frame 22 drives the placement frame 2 to move out from under the camera 34, the first rotating block 231 contacts the rotating rod 355 before the placement frame 2 is about to rotate above the second guide groove 351. Then the rotating frame 22 continues to rotate, which will drive the rotating block 231 to push the rotating rod 355 to rotate. At this time, the rotating rod 355 drives the second rotating disk 353 to rotate, and the second rotating disk 353 drives the torsion spring 354 to tighten. At the same time, the third rotating disk 357 is driven to rotate through the transmission rod 352. The turntable 357 can retract the top plate 35 into the second guide groove 351 through the cooperation of the slide groove 358 and the protrusion 359. When the through hole 211 of the placement frame 2 is aligned with the second guide groove 351, the first turn block 231 is separated from the rotating rod 355. At this time, the torsion spring 354 drives the second turntable 353 to rotate in the opposite direction. At this time, the third turntable 357 also rotates in the opposite direction to make the top plate 35 extend from the inside of the second guide groove 351 and enter the inside of the through hole 211. At this time, the top plate 35 can push the display screen module out of the inside of the placement frame 2, and the display screen module can be automatically taken out from the inside of the placement frame 2.
