[0032] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated below in conjunction with schematic diagrams, but is not limited thereto.

[0033] In the embodiments of the present invention, if there are directional indications (such as up, down, left, right, front, back, etc.), they are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0035] like Figure 1 As shown, an LED display screen splicing system includes: a main control module 1, a mounting base (please combine Figure 2 ), rotation drive unit 2, linear drive unit 3, displacement sensor assembly, sub-control module 5.

[0036] Specifically, the mounting base is used to install the LED display (please combine Figure 2), and the LED display screen is rotatably connected to the mounting base.

[0037] Specifically, the sub-control module 5 is arranged on the mounting seat, and the control switch 8 is electrically connected to the sub-control module 5 .

[0038] Specifically, the rotation drive unit 2 is used to drive the LED display screen to rotate. The rotation drive unit 2 is arranged on the mounting base. The rotation angle of the LED display screen is 90°. To ensure the accuracy of the rotation angle, the mounting base is also provided with an angle sensor 21 for detecting the rotation angle of the LED display screen. When the rotation angle reaches 90°, the rotation drive unit 2 stops driving the LED display screen to rotate.

[0039] Specifically, the linear drive unit 3 is used to drive the mounting seat to move linearly.

[0040] Specifically, the displacement sensor assembly is used to detect whether the mounting seat moves to the specified position, and the displacement sensor assembly includes an initial position sensor 41, an extreme position sensor 42, and a splicing position sensor 43. The displacement sensor assembly, the linear drive unit 3, and the sub-control module 5 are electrically connected to the main control module 1, respectively, and the rotation drive unit 2 is electrically connected to the sub-control module 5. Among them, the main control module 1 is provided with a counting unit 11, and the extreme position sensor 42 is electrically connected to the counting unit 11. The initial value of the counting unit 11 is 0. Each time the counting unit 11 passes through the extreme position sensor 42, the value of the counting unit 11 is counted by 1. When the main control module 1 determines that the count of the counting unit 11 is an even number, the mounting seat does not stop moving when passing the splicing position sensor 43. When the main control module 1 determines that the count of the counting unit 11 is an odd number, the linear drive unit 3 stops driving the mounting seat to move. When the mounting seat moves to the initial position sensor 41, the main control module 1 resets the count of the counting unit 11 to zero.

[0041] like Figure 2 As shown, an LED display screen splicing device adopts the above-mentioned LED display screen splicing system. The LED display screen splicing system includes: a base 100 and a splicing component. Among them, the main control module 1 is arranged on the base 100, and the number of splicing components in this embodiment is 4. In other embodiments, it can be selected according to the specific usage scenario.

[0042] Specifically, each splicing assembly includes a separate mounting seat 6 and a sub-control module arranged on the mounting seat 6, a rotation drive unit arranged on the mounting seat 6, a linear drive unit 3, a displacement sensor assembly arranged on the base 100, and an LED display screen 7 which is vertically mounted and horizontally rotatably connected to the mounting seat 6. The linear drive unit 3 drives the mounting seat 6 to move linearly along the base 100, and the displacement sensor assembly is arranged on the mounting seat 6, wherein the initial position sensor 41 is arranged at the initial position of the moving track of the mounting seat 6 of the splicing assembly, the limit position sensor 42 is arranged at the end of the moving track of the mounting seat 6 of the splicing assembly, and the splicing position sensor 43 is arranged at intervals from the initial position sensor 41 and is located at one end of the limit position sensor 42. Among them, the splicing position sensor 43 and the limit position sensor 42 of the innermost splicing assembly can be arranged at the same numerical position, and the splicing position sensor 43 of the outermost splicing assembly is arranged between the limit position sensor 42 and the initial position sensor 41.

[0043] Specifically, the main control module 1 is provided with a counting unit, and the limit position sensor 42 is electrically connected to the counting unit.

[0044] Specifically, when the LED display screen splicing device is unfolded, the LED display screens 7 of the multiple splicing components are arranged vertically in sequence. When viewed from the forward direction, the LED display screens 7 of the multiple splicing components are all on the same plane. In order to ensure the display effect after splicing, a certain gap standard needs to be met between adjacent LED display screens 7. The gap standard is mainly controlled by the position of the splicing position sensor 43.

[0045] Specifically, the linear drive unit 3 includes a drive motor, a lead screw transmission-connected to the drive motor, and a nut transmission-connected to the lead screw, wherein the nut is disposed on the mounting seat 6 .

[0046] Specifically, the rotary drive unit includes a rotary cylinder mounting seat 6 on which is also provided an angle sensor for detecting the rotation angle of the LED display screen 7 , and the LED display screen 7 is transmission-connected to the driving end of the rotary cylinder.

[0047] Specifically, the display screen splicing device further includes a control panel, and the control panel is provided with a control switch 8 electrically connected to the main control module 1 .

[0048] like Figure 3 As shown, the splicing components are all located at the position of the initial position sensor 41 on the base 100. At this time, the initial value of is 0.

[0049] like Figure 4 , Figure 5As shown, the user operates the control switch 8 on the control panel, and the LED display screen splicing device begins to unfold. Taking the outermost splicing component as an example, its action process is: the linear drive unit 3 drives the mounting seat 6 to move. When the mounting seat 6 moves to the splicing position sensor 43 for the first time, the main control module 1 queries the count, and when it is judged that the count is an even number, the mounting seat 6 does not stop moving when passing the splicing position sensor 43. When the mounting seat 6 moves to the extreme position sensor 42, the linear drive unit 3 stops driving the mounting seat 6 to move, and the main control module 1 sends a command to the sub-control module. The sub-control module controls the rotation drive unit to drive the LED display screen 7 to rotate. When the angle sensor detects that the LED display screen 7 rotates 90°, it stops rotating.

[0050] In specific implementation, the splicing action of each splicing component is carried out synchronously. When all the splicing components are moved to the extreme position and the LED display screen 7 is rotated, the main control module 1 sends a signal to the sub-control module, and the linear drive unit 3 of each splicing component drives its corresponding mounting seat 6 to move in the opposite direction to the splicing position sensor 43, and the count of the main control module 1 increases by 1. The main control module 1 determines that the count is an odd number, and the linear drive unit 3 stops driving the mounting seat 6 to move, and the splicing of the entire screen of the LED display screen splicing device is completed.

[0051] When the LED display screen splicing device is folded, taking the outermost splicing component as an example, the action process is as follows: the user operates the control switch 8 on the control panel, and the linear drive unit 3 moves in the opposite direction to the limit position sensor 42. At this time, the count of the main control module 1 increases by 1. At the same time, the main control module 1 sends a signal to the sub-control module, and the sub-control module controls the rotation drive unit to drive the LED display screen 7 to rotate. When the angle sensor detects that the LED display screen 7 rotates 90°, it stops rotating. In specific implementation, the splicing action of each splicing component is carried out synchronously. When all the splicing components are moved to the limit position and the LED display screen 7 is rotated, the main control module 1 sends a signal to the sub-control module, and the linear drive unit 3 of each splicing component drives its corresponding mounting seat 6 to move in the opposite direction to the splicing position sensor 43. The count determined by the main control module 1 is an even number, and the mounting seat 6 does not stop moving when passing the splicing position sensor 43. The mounting seat 6 continues to move to the initial position sensor 41, and the folding of the LED display screen splicing device is completed.

[0052] like Figure 6 As shown, a method for splicing an LED display screen is provided, wherein the method for splicing an LED display screen adopts the above-mentioned LED display screen splicing device. The method for splicing an LED display screen comprises an unfolding step, wherein the unfolding step comprises:

[0053] S1, the main control module controls the linear drive unit of the splicing component to drive the mounting seat to the position of the mounting limit position sensor corresponding to the splicing component;

[0054] S2, the sub-control module of the splicing component controls the rotation drive unit to drive the LED display to rotate 90°;

[0055] S3. The main control module controls the linear drive unit of the splicing component to drive the mounting seat to the position of the splicing position sensor corresponding to the splicing component.

[0056] The LED display screen splicing method also includes a folding step, and the unfolding step includes:

[0057] S4, the main control module controls the linear drive unit of the splicing component to drive the mounting seat to the position of the mounting limit position sensor corresponding to the splicing component;

[0059] S6. The main control module controls the linear drive unit of the splicing component to drive the mounting seat to the position of the initial position sensor corresponding to the splicing component.
