Description

Technical Field

[0001] This utility model relates to the field of flip structure technology, and in particular to a flip structure for LED screen processing. Background Technology

[0002] As LED display technology develops towards higher resolution and larger size, traditional manual flipping can no longer adapt to mass production. After 2010, the industry began to introduce automated flipping devices, such as robotic arms and rotating platforms, to achieve precise screen flipping, while integrating functions such as clamping and positioning to reduce manual intervention and improve consistency.

[0003] Most flip structures on the market flip the LED screen by clamping it with a clamping component. However, many flip structures lack an effective and convenient adjustment device, which makes it impossible to clamp and flip LED screens of different widths. Therefore, a flip structure for LED screen processing is needed. Utility Model Content

[0004] The purpose of this invention is to provide a flipping structure for LED screen processing, which solves the problem in the prior art that LED screens of different widths cannot be clamped and flipped.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flipping structure for LED screen processing, comprising a support base, a flipping assembly mounted on the support base, a support column mounted on the top side wall of the support base, one end of the support column being rotatably connected to the inner wall of one side of the top of the support base, and the other end passing through the other side wall of the top of the support base via a first bearing and fixedly connected to a rotating box, the rotating box containing a first threaded post with bidirectional threaded sections, the bidirectional threaded sections being fixedly connected by connecting posts, one end of the first threaded post being rotatably connected to the inner wall of one side of the rotating box, and the other end passing through the other side wall of the rotating box via a second bearing and fixedly connected to a hand crank. Each of the two-way threaded sections of the threaded column has two parallel movable plates connected by a first threaded groove. The movable plates are slidably connected to the inner wall of the rotating box. Hollow threaded columns are provided on the inner side of the two movable plates located in the same threaded section. The movable plates are rotatably connected to the two ends of the hollow threaded columns through a third bearing. A first rotating shaft parallel to the first threaded column is also rotatably connected to the inner wall of the rotating box. The two hollow threaded columns (with opposite thread directions) are fitted onto the outer wall of the first rotating shaft and slidably connected to it. The outer periphery of the hollow threaded columns is connected to a connecting plate by a second threaded groove. The other end of the two connecting plates extends to the outer side of the rotating box and is fixed with two relatively parallel clamping and fixing plates.

[0006] Preferably, a second slider is fixed to the side wall of the connecting plate away from the fixed plate, and a second slide rail that cooperates with the second slider is provided on the inner side wall of the rotating box.

[0007] Preferably, a first slider is fixed on the side of the movable plate near the support column, and a first slide rail that cooperates with the first slider is provided on the inner side wall of the rotating box.

[0008] Preferably, a first motor is fixed to the side wall of the rotating box, and a first rotating shaft is fixedly connected to the rotating end of the first motor. A limit plate is fixed to the side wall of the first rotating shaft along the axial direction. Matching limit grooves are opened at the contact points between the two hollow threaded columns and the limit plate. The limit plate and the first rotating shaft form a rotating structure through the drive of the first motor. The limit plate and the hollow threaded columns form a sliding structure through the limit grooves.

[0009] Preferably, the flipping assembly includes a second motor fixed to the upper surface of the bottom end of the support frame, a second rotating shaft provided at the rotating end of the second motor, a semi-conical gear fixed at the other end of the second rotating shaft, a first conical gear and a second conical gear provided on both sides above the semi-conical gear, the first conical gear and the second conical gear being fixedly connected to the support column, and during rotation, the semi-conical gear meshes with the first conical gear or the second conical gear, the semi-conical gear and the second rotating shaft forming a rotating structure through the drive of the second motor, the semi-conical gear meshing with the first conical gear, and the semi-conical gear meshing with the second conical gear.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. The flipping structure for LED screen processing is provided with a first threaded post and a first threaded groove. By turning the hand handle with external force, two sets of symmetrical first threaded posts can be driven to rotate. Through the threaded connection of the first threaded post and the first threaded groove, the rotation of the first threaded post can move the moving plate. During the movement of the moving plate, the hollow threaded post can be moved through the limiting plate and the limiting groove, which indirectly drives the connecting plate and the clamping and fixing plate to move. This allows adjustment of the relative clamping and fixing distance of the two sets of clamping and fixing plates, avoiding the inability to clamp and flip LED screens of different widths due to the lack of an effective and convenient adjustment device in the flipping structure. 2. The flipping structure for LED screen processing is equipped with a first bevel gear and a second bevel gear. By turning on the second motor, the second rotating shaft and the half-bevel gear can be driven to rotate. Since the tooth block on the outer side of the half-bevel gear is not a complete circle, when the side with the tooth block meshes with the first bevel gear or the second bevel gear respectively, it will drive the first bevel gear to rotate in the forward direction or the second bevel gear to rotate in the reverse direction. Thus, the same support column can rotate in both directions under different meshing conditions, thereby realizing the automatic flipping of the clamping component, which is convenient for flipping during LED screen processing.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, a flip structure for LED screen processing includes a support base 1, on which a flip assembly is mounted. A support column 3 is mounted on the top side wall of the support base 1. One end of the support column 3 is rotatably connected to the inner wall of the top side of the support base 1, and the other end passes through the other side wall of the top of the support base 1 via a first bearing 2 and is fixedly connected to a rotating box 4. The rotating box 4 contains a first threaded column 7 with bidirectional threaded sections, which are fixedly connected by connecting columns 8. One end of the first threaded column 7 is rotatably connected to the inner wall of the rotating box 4, and the other end passes through the other side wall of the rotating box 4 via a second bearing 5 and is fixedly connected to a hand handle 6. Two parallel movable plates are threadedly connected to the bidirectional threaded sections of the first threaded column 7 via first threaded grooves 9. 10. A first slider 11 is fixed on the side of the movable plate 10 near the support column 3. A first slide rail 12 that cooperates with the first slider 11 is provided on the inner wall of the rotating box 4. Hollow threaded columns 14 are provided on the inner side of the two movable plates 10 located in the same thread section. The movable plates 10 are rotatably connected to the two ends of the hollow threaded columns 14 through the third bearing 13. A first rotating shaft 21 parallel to the first threaded column 7 is also rotatably connected to the inner wall of the rotating box 4. The two hollow threaded columns 14 (the thread directions of the two hollow threaded columns 14 are opposite) are fitted on the outer wall of the first rotating shaft 21 and slidably connected to it. The outer periphery of the hollow threaded columns 14 is threadedly connected to the connecting plate 16 through the second threaded groove 15. The other end of the two connecting plates 16 extends to the outside of the rotating box 4 and is fixed with two clamping and fixing plates 17 that are arranged relatively parallel to each other.

[0015] The hand crank 6 forms a rotating structure with the rotating box 4 via the second bearing 5. The hand crank 6 forms a fixed structure with the connecting column 8 via the first threaded column 7. The first threaded column 7 forms a threaded connection with the moving plate 10 via the first threaded groove 9. The moving plate 10 forms a sliding structure with the first slide rail 12 via the first slider 11. The moving plate 10 forms a rotating structure with the hollow threaded column 14 via the third bearing 13. The hollow threaded column 14 forms a threaded connection with the connecting plate 16 via the second threaded groove 15. By rotating the hand crank 6 with external force, the first threaded column 7 can be rotated. Through the threaded connection between the first threaded column 7 and the first threaded groove 9, the rotation of the first threaded column 7 can move the two moving plates 10 on the two bidirectional threaded sections. During the movement of the moving plates 10, the hollow threaded columns 14 on the inner side of the two moving plates 10 can be moved along the axial direction of the first rotating shaft 21, indirectly driving the connecting plate 16 and the clamping and fixing plate 17 to move, thereby adjusting the relative clamping and fixing distance of the two sets of clamping and fixing plates 17.

[0016] Example 2 like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this embodiment further illustrates Example 1. A second slider 18 is fixed to the side wall of the connecting plate 16 away from the fixed plate 17, and a second slide rail 19 that cooperates with the second slider 18 is provided on the inner side wall of the rotating box 4.

[0017] A first motor 20 is fixed to the side wall of the rotating box 4. The rotating end of the first motor 20 is fixedly connected to the first rotating shaft 21. A limit plate 22 is fixed along the axial direction on the side wall of the first rotating shaft 21. Matching limit grooves 23 are provided at the contact points between the two hollow threaded columns 14 and the limit plate 22. The limit plate 22 and the first rotating shaft 21 form a rotating structure through the drive of the first motor 20. The limit plate 22 and the hollow threaded column 14 form a sliding structure through the limit grooves 23. When the first motor 20 is turned on, the first rotating shaft 21 and the limit plate 22 can be rotated. Due to the action of the limit plate 22, the hollow threaded column 14 sleeved on the outer wall of the first rotating shaft 21 will rotate accordingly. The rotation of the hollow threaded column 14 can cause the two connecting plates 16 threaded to it to move closer or further away, thereby driving the clamping and fixing plate 17 to move. The relative movement of the two sets of clamping and fixing plates 17 can form a clamping and fixing assembly, which facilitates the clamping and fixing of the LED screen.

[0018] Example 3 like Figure 1 and Figure 2 As shown, this embodiment further illustrates Example 1. The flipping assembly includes a second motor 24 fixed to the upper surface of the bottom end of the support base 1. The rotating end of the second motor 24 is provided with a second rotating shaft 25. The other end of the second rotating shaft 25 is fixed with a semi-conical gear 26. A first conical gear 27 and a second conical gear 28 are provided on both sides above the semi-conical gear 26. Both the first conical gear 27 and the second conical gear 28 are fixedly connected to the support column 3. When rotating, the semi-conical gear 26 meshes with the first conical gear 27 or the second conical gear 28. The semi-conical gear 26 and the second rotating shaft 25 form a rotating structure through the drive of the second motor 24. When rotating, the semi-conical gear 26 meshes with the first conical gear 27 and the second conical gear 28.

[0019] The first bevel gear 27 forms a fixed structure with the second bevel gear 28 through the support column 3. When the second motor 24 is turned on, it can drive the second rotating shaft 25 and the half bevel gear 26 to rotate. Since the tooth block on the outer side of the half bevel gear 26 is not a full circle, when the side with the tooth block meshes with the first bevel gear 27 or the second bevel gear 28 respectively, it will drive the first bevel gear 27 to rotate in the forward direction or the second bevel gear 28 to rotate in the reverse direction. Thus, the same support column 3 can rotate in both directions under different meshing conditions, thereby realizing the automatic flipping of the clamping component, which is convenient for flipping during LED screen processing. If a 180-degree rotation is not required, a half-bevel gear with the same outer radius as the first or second bevel gear can be selected. The number of tooth blocks on the surface of the half-bevel gear 26 is set to be slightly less than the number of tooth blocks in half a circle, depending on the rotation angle. If a 180-degree rotation is required, a half-bevel gear with a radius slightly larger than the first or second bevel gear can be selected. On this basis, the number of tooth blocks on the half-bevel gear is set to half the number of tooth blocks in a full circle on the first or second bevel gear, ensuring that both bevel gears can rotate 180 degrees, while avoiding the situation where the half-bevel gear meshes with both bevel gears at the same time and gets stuck.

[0020] Working principle: First, by rotating the hand handle 6 with external force, the double threaded section of the first threaded column 7 can be rotated. The rotation of the first threaded column 7 can move the moving plate 10. During the movement of the moving plate 10, the hollow threaded column 14 can be moved through the limiting plate 22 and the limiting groove 23, which indirectly drives the connecting plate 16 and the clamping and fixing plate 17 to move, so that the relative clamping and fixing distance of the two sets of clamping and fixing plates 17 can be initially adjusted. Secondly, by turning on the first motor 20, the first rotating shaft 21 and the limiting plate 22 can be driven to rotate, which indirectly drives the hollow threaded column 14 to rotate. The rotation of the hollow threaded column 14 can move the connecting plate 16 and the clamping and fixing plate 17. The relative movement of the two sets of clamping and fixing plates 17 can form a clamping and fixing assembly, which facilitates the clamping and fixing of the LED screen. The clamping and fixing plate 17 has a groove on its inner side to limit the LED screen. An elastic buffer pad can also be set in the groove to avoid damaging the LED screen. Then, by turning on the second motor 24, the second rotating shaft 25 and the half-bevel gear 26 can be driven to rotate. Since the tooth block on the outer side of the half-bevel gear 26 is not a complete circle, when the side with the tooth block meshes with the first bevel gear 27 or the second bevel gear 28 respectively, it will drive the first bevel gear 27 to rotate in the forward direction or the second bevel gear 28 to rotate in the reverse direction. Thus, the same support column 3 can rotate in the forward and reverse directions under different meshing conditions, thereby realizing the automatic flipping of the clamping component, which is convenient for flipping during LED screen processing.
