[0020] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] See also Figures 1 to 4In a preferred embodiment of the present invention, the OLED tray up and down transmission device 20 comprises a box body 1, a drawer 2 arranged on the box body 1, a first transmission mechanism 3 arranged on the drawer 2, and a lifting mechanism (not shown) arranged on the box body 1 for up and down transmission of the OLED tray 4, and a guide mechanism (not shown) for lateral transmission with the first transmission mechanism 3. A guide rail (not shown) is arranged between the drawer 2 and the box body 1. A handle 21 is arranged on one side of the drawer 2, and the handle 21 is arranged on the outside of the drawer 2, which is used to pull out the drawer 2, which is convenient and fast. A small wheel 13 is installed at the bottom of the box body 1, and the small wheel 13 is arranged at the front end, rear end and middle of the bottom of the box body 1. A small wheel 13 is arranged on both sides of the front end, rear end and middle. Of course, in other embodiments, the small wheel 13 can also be installed at other positions, depending on the actual situation. The guide mechanism cooperates with the first transmission mechanism 3 to move the OLED tray 4 out to the outside for the staff to load. The first transmission mechanism 3 is also provided with a handle, and the handle 3 is arranged on the outside of the first transmission mechanism 3 in the same direction as the handle 21 .

[0022] The box body 1 also includes a first opening 11 and a second opening 12. The height of the first opening 11 is lower than that of the second opening 12. The first transmission mechanism 3 and the guide mechanism are arranged at the first opening 11 and the second opening 12 are flush with the first opening 11. The height of the drawer 2 is flush with the first opening 11. The lifting mechanism is arranged at the back of the box body 1 at the second opening 12. A non-return buckle device for limiting the height and a side positioning clamping device 121 for fixing the OLED tray 4 are arranged at the top of the second opening 12. When the OLED tray 4 moves to the top of the second opening 12, the non-return buckle device holds the OLED tray 4 to prevent the OLED tray 4 from continuing to move upward, and then the side positioning clamping device 121 clamps and fixes the OLED tray 4. A sensor is arranged on the side positioning clamping device 121, and the sensor senses the position of the OLED tray 4 for positioning.

[0023] The present invention also provides a display device, which includes a frame 21, a movable intermediate transfer platform 22 arranged on the frame 21, and several OLED tray upper and lower transmission devices 20 and a transfer transmission device 23 as described above, which are arranged on the frame 21; wherein, several OLED tray upper and lower transmission devices 20 are closely arranged on the frame, saving space, and can be placed on a large-screen splicing wall according to the requirements of large-screen display. The transfer transmission device 23 is arranged in the middle of the frame, which can streamline the structure, shorten the cycle time, and improve the overall operation efficiency. The intermediate transfer platform 22 is arranged at the bottom of the OLED tray upper and lower transmission device 20. wherein, the intermediate transfer platform 22 is movable, and the intermediate transfer platform 22 can be placed under any one of the OLED tray upper and lower transmission devices 20 to move it out to the outside of the frame for easy repair and maintenance.

[0024] In summary: by arranging the first transmission mechanism 3 and the lifting mechanism on the box body 1, the upper and lower transmission devices 20 of the OLED tray are simplified, the size is reduced, and the efficiency is improved;

[0025] By closely arranging a plurality of OLED tray upper and lower transmission devices 20 on the frame, the transmission efficiency is improved.
