Description

Technical Field

[0001] This utility model relates to the field of LED display processing technology, and in particular to a multi-angle flipping device for processing high-definition LED displays. Background Technology

[0002] An LED display screen is a flat panel display composed of small LED module panels. It is used to display various information such as text, images, and videos. During the manufacturing process, both sides of the display screen need to be assembled and tested. That is, after one side of the LED display screen is processed, it needs to be flipped to the other side so that the other side can be processed.

[0003] For example, patent publication number CN212071702U, published on 2020-12-04, discloses a flipping device for processing high-definition LED displays, including a base frame and a table. The bottom end of the base frame contacts the ground, and the top end of the base frame is connected to the middle of the bottom end of the table. It also includes two sets of bearing plates, side support plates, and a top plate. The output end of the lead screw drive is connected to the top end of the lead screw, the outer wall of the lower end of the lead screw is connected to the inner wall of the bearing, and the outer wall of the bearing is connected to the inner wall of the bearing plate. The inner sections of the two sets of side support plates are connected to the inner ends of a set of cabinet channels. The middle right end of the slider is connected to the left end of the rotating tube. The right end of the rotating tube is rotatably connected to the left end of the rotating rod. The right end of the rotating rod is connected to the middle left end of the placement rack. The outer walls of the lower ends of the two sets of clamping bolts are screwed to the inner walls of the upper end of the placement rack. The lower ends of the clamping bolts are rotatably connected to the front and rear ends of the top of the clamping plate. The lower end of the rotating tube locking bolt is screwed to the upper end of the rotating tube. The connection method of the other set is symmetrical to that of the previous set through the middle surface of the table. However, the above solution still has some shortcomings in actual use. For example, in use, the display screen is clamped and limited only by two clamping plates and clamping bolts, resulting in a small force-bearing area for the display screen. During the processing of the display screen, the processing pressure is easily too high, which can damage the display screen, thus causing low efficiency in the processing of LED display screens.

[0004] Based on the above, this utility model proposes a multi-angle flipping device for processing high-definition LED displays. Summary of the Invention

[0005] In order to overcome the disadvantage that the small force-bearing area of ​​the display screen makes it easy to damage the display screen due to excessive processing pressure during processing, this utility model proposes a multi-angle flipping device for processing high-definition LED display screens.

[0006] The technical solution of this utility model is: a multi-angle flipping device for processing high-definition LED displays, including a base, a flipping frame, a rotating shaft, a transmission assembly, a first motor, a clamping frame, a first spring, a guide rod, a first limiting frame, and a second limiting frame. The flipping frame is rotatably connected to both the left and right sides of the upper part of the base, and a rotating shaft is rotatably connected between the left and right sides of the lower part of the base. The first motor is installed on the left side of the base, and the output shaft on the right side of the first motor is fixedly connected to the rotating shaft via a coupling. Transmission assemblies are wound around both the left and right sides of the rotating shaft and the adjacent flipping frames. Each transmission assembly consists of two pulleys and a flat belt. The wheels are fixed to the left and right sides of the rotating shaft, and the other two pulleys are fixed to the tilting frame. A flat belt is wound around each of the two vertical pulleys. The tilting frames on both sides are slidably connected to the clamping frames. The clamping frames are connected to the adjacent tilting frames by symmetrically distributed first springs, which are wound around the adjacent clamping frames. The clamping frames on both sides are fixed to symmetrically distributed guide rods. The two guide rods on the right side are slidably connected to the first limiting frame, and the two guide rods on the left side are slidably connected to the second limiting frame. The adjacent first limiting frame and second limiting frame are also slidably connected.

[0007] More preferably, it also includes mounting blocks, screws, and a second motor. Mounting blocks are fixed to the left side of both second limit frames, and a second motor is mounted on the left clamping frame. The output shafts on both the front and rear sides of the second motor are connected to screws via couplings, and the screws are threadedly connected to the adjacent mounting blocks.

[0008] More preferably, it also includes a mounting plate, a fixing block, a plug rod, and a second spring. The mounting plate is fixedly connected to the flip frame on the right side, and the fixing block is fixedly connected to the upper right side of the base. The plug rod is slidably connected inside the fixing block, and the plug rod is also slidably connected to the mounting plate. A second spring is connected between the plug rod and the fixing block, and the second spring is wound around the plug rod.

[0009] More preferably, it also includes mounting rods, guide seats and top frames, with guide seats fixedly connected to the front of the left and right tilting frames, and top frames slidably connected between the left and right guide seats, and mounting rods fixedly connected to the left and right clamping frames.

[0010] More preferably, the upper left and right sides of the base have circular grooves, and the flip frame slides in the adjacent grooves.

[0011] More preferably, the clamping frame, the first limiting frame and the second limiting frame are all provided with sponge on the side that is close to each other.

[0012] Beneficial effects: This utility model first clamps the LED display screen around its perimeter using a clamping frame, a first limiting frame, and a second limiting frame, which increases the force-bearing area of ​​the LED display screen, making the force on each part of the LED display screen more balanced when it is flipped, reducing the risk of damage to the display screen and improving work efficiency.

[0013] This invention, through the installation plate and plug rod, can prevent the LED display screen from rotating before processing and inspection are completed due to the misrotation of the first motor, thereby reducing the probability of damage to the LED display screen and improving work quality.

[0014] This invention, through its top frame and mounting rod, makes placing and retrieving parts more convenient, thereby improving work efficiency. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings. Example

[0024] A multi-angle flipping device for processing high-definition LED displays, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a base 1, a tilting frame 2, a rotating shaft 21, a transmission assembly 3, a first motor 4, a clamping frame 5, a first spring 6, a guide rod 7, a first limiting frame 8, and a second limiting frame 9. The tilting frames 2 are symmetrically distributed and rotatably connected to the upper part of the base 1. The rotating shaft 21 is rotatably connected between the left and right sides of the lower part of the base 1. The first motor 4 is installed on the left side of the base 1. The output shaft on the right side of the first motor 4 is fixed to the rotating shaft 21 via a coupling. Transmission assemblies 3 are wound around the left and right sides of the rotating shaft 21 and the adjacent tilting frames 2. Each transmission assembly 3 consists of two pulleys and a flat belt. The two pulleys are fixed to the left and right sides of the rotating shaft 21, respectively, and the other two pulleys are fixed to the tilting frames 2. A flat belt is wound around each of the two vertical pulleys. The device includes two clamping frames 5, which are slidably connected to the flipping frame 2. Each clamping frame 5 and the adjacent flipping frame 2 is connected by a symmetrically distributed first spring 6, which is wound around the adjacent clamping frame 5. There are four guide rods 7, which are fixed to the front and rear sides of the two clamping frames 5. The two guide rods 7 on the right side are slidably connected to a first limiting frame 8, and the two guide rods 7 on the left side are slidably connected to a second limiting frame 9. The adjacent first limiting frames 8 and second limiting frames 9 are also slidably connected. The upper left and right sides of the base 1 have circular sliding grooves, and the flipping frame 2 slides in the adjacent sliding grooves. The clamping frames 5, the first limiting frames 8, and the second limiting frames 9 are all provided with sponge on the side that is close to each other.

[0025] like Figure 3 and Figure 4 As shown, it also includes a mounting block 10, a screw 11, and a second motor 12. There are two mounting blocks 10, which are fixed to the left side of the two second limit frames 9 respectively. The second motor 12 is mounted on the clamping frame 5 on the left side. The output shafts on both the front and rear sides of the second motor 12 are connected to the screw 11 through couplings. The screw 11 is threadedly connected to the adjacent mounting block 10.

[0026] When using this device, the operator first controls the second motor 12 to drive the screw 11 to rotate forward, thereby causing the second limiting frame 9 to separate outward. The second limiting frame 9 will then cause the first limiting frame 8 to separate outward as well. Next, the two clamping frames 5 are pushed outward, causing the first spring 6 to deform. Then, the left wide edge of the LED display screen to be processed is centered in the left clamping frame 5, and the LED display screen is kept horizontal. The two clamping frames 5 are released, and under the action of the first spring 6, the clamping frames 5 move inward to clamp the left and right sides of the LED display screen. Then, the operator continues to control the second motor 12 to drive the screw 11 to rotate in the opposite direction, thereby causing the first limiting frame 8 and the second limiting frame 9 to move inward to clamp the front and rear sides of the LED display screen. At this time, the LED display screen is completely clamped on all sides, and the operator can begin processing and inspecting the front of the LED display screen. After processing and inspection are completed, the operator continues to control the first motor 4 to connect with the rotating shaft 21 through the transmission component 3. Rotating the flipping frame 2 180 degrees will cause the clamping frame 5, the first limiting frame 8, the second limiting frame 9, and the LED display screen to rotate 180 degrees together. Workers can then begin processing and inspecting the reverse side of the LED display screen. After both sides of the LED display screen have been processed and inspected, the second motor 12 is controlled to rotate the screw 11 in the forward direction. The first limiting frame 8 and the second limiting frame 9 will no longer clamp the LED display screen. Then, the clamping frame 5 is moved outwards away from the LED display screen, causing the first spring 6 to deform again. The processed and inspected LED display screen can then be removed, releasing the clamping frame 5. Under the elastic action of the first spring 6, the clamping frame 5 moves inwards to reset. In summary, by first clamping the LED display screen around its perimeter using the clamping frame 5, the first limiting frame 8, and the second limiting frame 9, the force-bearing area of ​​the LED display screen can be increased, ensuring balanced force distribution across all parts during flipping, reducing the risk of damage to the display screen, and improving work efficiency. Example

[0027] Based on Example 1, such as Figure 1 , Figure 5 and Figure 6 As shown, it also includes a mounting plate 13, a fixing block 14, a plug rod 15, and a second spring 16. The mounting plate 13 is fixed to the flip frame 2 on the right side, the fixing block 14 is fixed to the upper right side of the base 1, the plug rod 15 is slidably connected to the fixing block 14, and the plug rod 15 is also slidably connected to the mounting plate 13. A second spring 16 is connected between the plug rod 15 and the fixing block 14, and the second spring 16 is wound around the plug rod 15.

[0028] When multi-angle flipping processing of the LED display screen is required, the operator can first pull the plug rod 15 to the right to separate it from the mounting plate 13. The second spring 16 will deform, and then control the first motor 4 to rotate at a certain angle. As can be seen from the above steps, the flipping frame 2 will drive the LED display screen and the mounting plate 13 to flip together at a certain angle. Then, release the plug rod 15. Under the elastic action of the second spring 16, the plug rod 15 will slide to the left and be inserted into the mounting plate 13. In this way, when the display screen has finished rotating, the plug rod 15 is inserted into the mounting plate 13 to hold it in place. In summary, the mounting plate 13 and the plug rod 15 can prevent the LED display screen from rotating before the processing and inspection are completed due to the accidental rotation of the first motor 4, thereby reducing the probability of damage to the LED display screen and improving the work quality.

[0029] like Figure 1 and Figure 7 As shown, it also includes mounting rods 17, guide seats 18, and top frame 19. There are two guide seats 18, which are fixed to the front of the left and right flip frames 2 respectively. The top frame 19 is slidably connected between the two guide seats 18. There are two mounting rods 17, which are fixed to the left and right clamping frames 5 respectively.

[0030] When it is necessary to place and clamp the LED display screen between the clamping frames 5, the operator can push the top frame 19 backward. The top frame 19 will cause the mounting rod 17 to separate outward, thereby causing the clamping frame 5 to move outward. The first spring 6 will deform. Then, according to the above steps, the LED display screen is placed between the clamping frames 5. The top frame 19 is released. Under the elastic action of the first spring 6, the clamping frame 5 causes the mounting rod 17 to move inward, clamping the display screen. The mounting rod 17 pushes the top frame 19 forward to its original position. Similarly, when the LED display screen needs to be removed after processing and testing, it can also be quickly removed by pushing the top frame 19. In summary, the top frame 19 and the mounting rod 17 make placing and removing parts more convenient and improve work efficiency.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
