[0054] The screen carrier plate 100 is preferably but not limited to a rectangular plate structure, and is used to support a flexible screen (not shown in the figure) on the top of the screen carrier plate 100. One of the sides of the screen carrier plate 100 is an entrance end 101 for entering and exiting the flexible screen, so as to facilitate sliding the flexible screen into the top of the screen carrier plate 100.

[0055] The pre-pressing assembly 200 is provided in plurality, and the plurality of pre-pressing assemblies 200 are arranged around the screen carrier plate 100. The plurality of pre-pressing assemblies 200 press the flexible screen onto the screen carrier plate 100 so that the four sides of the flexible screen are pressed tightly against the screen carrier plate 100 to prevent the flexible screen from sliding off the screen carrier plate 100.

[0056] The pushing mechanism 300 is provided in plurality, and the plurality of pushing mechanisms 300 are respectively located on two adjacent sides of the screen supporting plate 100. The pushing mechanisms 300 on the two adjacent sides of the screen supporting plate 100 push the flexible screen toward the other two adjacent sides and then position it, so as to position the flexible screen on the screen supporting plate 100.

[0057] The carrier for a large-size flexible screen in an embodiment of the present application is provided with a screen carrier plate 100 for carrying the flexible screen. The screen carrier plate 100 is used to provide support and protection for the flexible screen during assembly and testing, thereby preventing damage to the flexible screen caused by continuous bending and movement during assembly or testing.

[0058] The screen carrier plate 100 is also provided with a pre-pressing assembly 200 for pressing the flexible screen onto the screen carrier plate 100. The pre-pressing assembly 200 can press the flexible screen onto the screen carrier plate 100 to prevent it from detaching from the screen carrier plate 100. The screen carrier plate 100 is also provided with a pushing mechanism 300, which is used to position the flexible screen on the screen carrier plate 100 to prevent the flexible screen from sliding on the screen carrier plate 100.

[0059] In some alternative embodiments: See Figure 1 、 Figure 2 、 Figures 4 to 9 As shown, an embodiment of the present application provides a jig for a large-size flexible screen, wherein the pre-pressing component 200 of the jig for a large-size flexible screen includes a first pre-pressing component 220 located at the inlet end 101 of the screen carrier plate 100, and a second pre-pressing component 210 located on the remaining three sides of the screen carrier plate 100.

[0060] The first pre-pressing assembly 220 is detachably connected to the top of the screen carrier plate 100. This allows the first pre-pressing assembly 220 to be removed from the inlet end 101 of the screen carrier plate 100 when installing or removing the flexible screen. Once the flexible screen is installed on the screen carrier plate 100, the first pre-pressing assembly 220 is installed at the inlet end 101 of the screen carrier plate 100. The second pre-pressing assembly 210 is fixedly connected to the top of the screen carrier plate 100.

[0061] Specifically, the first pre-pressing assembly 220 includes a socket 221 inserted into the screen carrier plate 100, a socket on the top of the screen carrier plate 100 that is adapted to the socket 221, and an L-shaped pressing plate 222 located on the socket 221 and rotatably connected to the socket 221. The L-shaped pressing plate 222 can rotate freely on the socket 221. When the L-shaped pressing plate 222 flips over to contact the flexible screen, it presses the flexible screen against the screen carrier plate 100.

[0062] One end of the L-shaped pressure plate 222 is provided with a first magnet 224 that attracts the socket 221, and the socket 221 is provided with a third magnet 225 that attracts the first magnet 224.

An L-shaped pressure plate 222 is located on the hinge seat 211 and is rotatably connected to the hinge seat. A first magnet 224 is provided at one end of the L-shaped pressure plate 222, which is attracted to the hinge seat 211. A second magnet 223 is provided at the other end of the L-shaped pressure plate 222, which is attracted to the screen support plate 100.

[0066] The first pre-pressing assembly 220 of the embodiment of the present application includes a socket 221 inserted into the screen carrier plate 100, and an L-shaped pressure plate 222 located on the socket 221 and rotatably connected to the socket 221; a first magnet 224 that is attracted to the socket 221 is provided at one end of the L-shaped pressure plate 222, and a second magnet 223 that is attracted to the screen carrier plate 100 is provided at the other end of the L-shaped pressure plate 222.

[0067] The socket 221 of the first pre-pressing component 220 is plugged and unplugged into the screen carrier plate 100, which facilitates the disassembly of the first pre-pressing component 220. The L-shaped pressure plate 222 is respectively provided with a first magnet 224 that attracts the socket 221 and a second magnet 223 that attracts the screen carrier plate 100, so that the L-shaped pressure plate 222 can be kept in a stable state after being flipped to a certain position.

The pushing mechanism 300 interacts with the position-limiting components to position the flexible screen on the screen carrier plate 100.

[0074] The limiting assembly includes a lifting limiting assembly 400 located at the inlet end 101 of the screen supporting plate 100, and a fixed limiting assembly 500 located on the other side of the screen supporting plate 100. The lifting limiting assembly 400 includes a limiting base 401 fixedly connected to the screen supporting plate 100, and a limiting slider 402 slidably connected to the limiting base 401. The limiting slider 402 slides up and down on the limiting base 401.

[0075] The limit base 401 is provided with a limit screw 404 that is slidably connected to the limit slider 402. The limit screw 404 limits the rising height of the limit slider 402.
