[0037] A fixed shaft 5 is screwed onto a bearing seat 4;

[0038] Mounting bracket 6 is fixedly mounted on the fixed shaft 5;

The support frame 12, the screwing shaft of the mounting frame 6, and the rotating shaft of the stepper wheel 7 are coaxial.

[0046] Splined shaft 14, which is spun onto clamping frame 3 via bearings;

[0047] Spline sleeve 16, the spline sleeve 16 is screwed onto the mounting base 10 via a bearing, and the spline sleeve 16 is movably sleeved on the spline shaft 14. The spline sleeve 16 and the support shaft 11 are connected by a bevel gear set.

[0050] When using this device, place the clamping frame 3 flat, and then place the screen to be tested on the lower clamping frame 3. When placing the screen, first push the telescopic frame 9 through the telescopic hydraulic rod 13, and then the telescopic frame 9 pushes the mounting base 10. The mounting base 10 pushes the support frame 12 to move through the support shaft 11, and the support frame 12 pushes the mounting frame 6 to rotate. The mounting frame 6 drives the stepping wheel 7 and the support wheel 8 to move upward and extend out of the clamping frame 3, with the stepping wheel 7 set higher than the support wheel 8. Then, insert the screen from the end of the lower clamping frame 3 away from the tray 23 into the upper and lower clamping frames 3. The screen is positioned between the upper and lower clamping frames 3, with the stepper wheel 7 resting on the lower clamping frame 3. The stepper motor 15 drives the spline shaft 14 to rotate, which in turn drives the spline sleeve 16. The spline sleeve 16, via a bevel gear set, drives the support shaft 11 to rotate, which in turn drives the transmission shaft 17. The transmission shaft 17, via the bevel gear set, drives the stepper wheel 7 to rotate. This causes the stepper wheel 7 on the lower clamping frame 3 to push the screen between the upper and lower clamping frames 3. Then, the telescopic hydraulic rod 13 resets the telescopic frame 9, causing the mounting bracket 6 to rotate and retract into the clamping frame 3. Inside, the support wheel 8 is positioned above the clamping frame 3 and the stepping wheel 7 is positioned below the support wheel 8. Then, the clamping frame 3 is rotated so that the end with the support plate 23 is tilted downwards by 3-5°, so that the screen is supported and slid by the support wheel 8, and the screen rests against the support plate 23. Then, the mounting frame 6 is adjusted again so that the mounting frame 6 drives the stepping wheel 7 and the support wheel 8 to be completely retracted into the clamping frame 3, so that the screen is mounted on the lower clamping frame 3. The dual-axis motor 21 drives the drive shaft 22 to rotate, and the drive shaft 22 drives the threaded rod 20 to rotate through the bevel gear set, thereby the threaded rod 20 rotates. The lever 20 pushes the upper and lower lifting seats 19 closer together, which in turn drives the upper and lower clamping frames 3 to clamp the screen. Then, the rotary cylinder 24 drives the rotating frame 2 to rotate 180°, thus flipping the screen. When the flipped screen is sent out, the upper and lower clamping frames 3 are opened. Then, the stepper wheel 7 in the lower clamping frame 3 extends upward and supports the screen. Then, the stepper motor 15 rotates in the opposite direction, thereby pushing the stepper wheel 7 to rotate. The screen is pushed out of the clamping frame 3 by the stepper wheel 7.

[0051] Compared with the prior art, the beneficial effects of this utility model are:

[0052] 1. This device is equipped with a set of clamping frames 3 that are symmetrical in the upper and lower parts and two sets that are symmetrical in the left and right parts, so that when the screen is flipped, the clamping frames 3 can clamp and fix the two sides of the screen and flip it.

[0055] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
