[0018] like Figure 1 As shown, this utility model provides a folding screen testing device under X-ray field, including a folding device 17 installed on a mobile device 1, an X-ray source 18 and a flat panel detector 8 located on both sides of the folding device 17, and the flat panel detector 8 installed on a mobile device 2.

[0019] Both Mobile Device 1 and Mobile Device 2 are single-axis robots, electric linear guides, or electric lead screws, etc.

[0020] The folding screen is placed inside the folding device 17, which controls the rotation of the folding screen to detect the folding state of the folding screen. At the same time, the actual dynamic changes of the internal structure of the hinge used for folding of the folding screen are detected by the X-ray field, so that the dynamic and static detection of the folding screen hinge can be performed more accurately.

[0021] For details, please refer to the following: Figure 2The folding device 17 includes a fixed end lower bracket 6, a servo motor 10 installed in the fixed end lower bracket 6, a turntable 9 installed on the servo motor 10, a rotating end intermediate clamp 3 installed on the turntable 9 via a rotating end positioning plate 5, a rotating end upper clamp 2 locked to the rotating end intermediate clamp 3 by a knurled hand screw 1, and the rotating end upper clamp 2 fixes one side of the folding screen 4 to the rotating end intermediate clamp 3, thereby allowing the knurled hand screw 1 to be adjusted to accommodate different specifications of the folding screen 4; and a fixed end intermediate clamp 13 installed in the fixed end lower bracket 6, a fixed end upper clamp 11 locked to the fixed end intermediate clamp 13 by a knurled hand screw 1, and the fixed end upper clamp 11 fixes the other side of the folding screen 4 to the fixed end intermediate clamp 13.

[0022] The servo motor 10 used allows for control of rotation speed and stopping angle, enabling the foldable screen 4 to rotate at any speed and stop at any angle, thus diversifying the detection methods.

[0023] Furthermore, to prevent the other side of the folding screen 4 from shaking, the folding device 17 also includes a fixed end locking plate 12 mounted on the fixed end clamp 11 and the fixed end intermediate clamp 13.

[0024] Furthermore, in order to avoid damage caused by excessive folding of the folding screen 4, a limit screw 14 and a limit switch 15 are installed on the middle clamp 13 at the fixed end. The limit screw 14 is used to prevent the folding screen 4 from colliding with the fixed end due to excessive folding, while the limit switch 15 is used to reverse or stop the servo motor 10 when the folding screen 4 is folded into place.

[0025] Furthermore, to prevent dust from entering the servo motor 10 and affecting its operation, the servo motor 10 is covered with a motor cover 7, and the motor cover 7 is installed inside the fixed end bracket 6.

[0026] In order to electrically connect the servo motor 10 to the control panel, the fixed end lower bracket 6 is also provided with a wiring interface 16, through which the servo motor 10 is connected to the control panel.

[0027] The X-ray source 18, flat panel detector 8, servo motor 10, and limit switch 15 are communicatively coupled to the control panel.

[0028] The control panel contains a PLC controller, which is a programmable numerical control system. The PLC acts as the central control system, using a touchscreen to input programs and control the entire machine, achieving full automation of the transportation process. The control system connects various actuators, allowing them to move along logical trajectories. Programming controls enable these actuators to operate according to the required steps.

[0029] The working principle of this utility model is as follows:

[0030] First, the staff fixes the two sides of the folding screen 4 to the rotating end middle clamp 3 and the fixed end middle clamp 13 respectively. Then, the X-ray source 18, the flat panel detector 8 and the servo motor 10 are turned on. Driven by the servo motor 10, the folding screen 4 begins to rotate until the rotating end positioning plate 5 touches the limit switch 15. The limit switch 15 sends a feedback signal, and then the servo motor 10 reverses. At this time, the flat panel detector 8 feeds back the dynamic and static states of the hinge of the folding screen 4.

[0031] This device enables the folding screen 4 to be detected under a radiation field, thereby accurately reflecting the dynamic and static states of the hinge.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
