[0025] Among them, the flipping structure is achieved by starting the servo motor 5, the servo motor 5 drives the first gear 8 to rotate, the first gear 8 drives the second gear 10 to rotate, and the second gear 10 drives the pushing component 6 to rotate to the right, thereby pushing the display screen onto the output conveyor belt 2.

[0026] Furthermore, the first gear 8 and the second gear 10 are engaged with each other, the rotating shaft 9 is fixedly connected to the center of the fixed bearing 11 , and the top end of the rotating shaft 9 is fixedly connected to the bottom end of the pushing assembly 6 .

[0027] The top of the rotating shaft 9 is flush with the top of the rotating disk 3, so that when the pushing component 6 is turned over, its bottom end just contacts the top of the rotating disk 3, which can more accurately push the display screen to the next device.

[0028] Furthermore, the pushing assembly 6 includes a fixed box 12, a mounting port 13, a first motor 14, a pushing plate 15, and a soft pad 16. The mounting port 13 is arranged at the top of the fixed box 12, the first motor 14 is fixedly connected to the outer wall of the fixed box 12, the pushing plate 15 is rotatably connected to the inner wall of the mounting port 13, and the soft pad 16 is arranged on the outer wall of the pushing plate 15 close to the display screen.

[0029] Among them, the output end of the first motor 14 passes through the outer wall of the fixed box 12 and is fixedly connected to the outer wall of the push plate 15, so that the first motor 14 can drive the push plate 15 to flip 90 degrees until it contacts the surface of the rotating disk 3 and stops.

[0030] Furthermore, the protective device 7 includes a hollow shell 17, a lifting plate 18, a second motor 19, a screw 20, a limit rod 21, and a stop block 22.

[0031] Among them, the protective device 7 starts the second motor 19, the second motor 19 drives the screw 20 to rotate, and the screw 20 pushes the lifting plate 18 to move up and down along the limit rod 21, thereby preventing the display screen from being thrown out from the outer wall of the rotating disk 3 when the speed of the rotating disk 3 increases.

[0032] Furthermore, the lead screw 20 is threadedly connected to the lifting plate 18 , the stopper 22 is fixedly connected to the top end of the lead screw 20 , and the limiting rod 21 is slidably connected to the lifting plate 18 .

[0033] The shapes of the hollow shell 17 and the lifting plate 18 are adapted to the outer wall of the rotating disk 3 , and the stopper 22 is arranged inside the lifting plate 18 so that the lifting plate 18 will not separate from the hollow shell 17 when it rises to the limit position.

[0034] Working principle: After the display screen is detected on the rotating disk 3, the first motor 14 is started first, and the first motor 14 drives the pushing plate 15 to flip 90 degrees until it contacts the surface of the rotating disk 3 and stops. Then the servo motor 5 is started, and the servo motor 5 drives the first gear 8 to rotate, and the first gear 8 drives the second gear 10 to rotate, and the second gear 10 drives the pushing assembly 6 to rotate to the right, thereby pushing the display screen onto the output conveyor belt 2. After the pushing is completed, the first motor 14 lifts the pushing plate 15, and the servo motor 5 drives the rotating shaft 9 to return to its original position to push the next display screen; when the speed of the rotating disk 3 increases, the second motor 19 is started, and the second motor 19 drives the screw 20 to rotate, and the screw 20 pushes the lifting plate 18 to move up and down along the limit rod 21, thereby preventing the display screen from being thrown out from the outer wall of the rotating disk 3 when the speed of the rotating disk 3 increases.
