Description

Technical Field

[0001] This utility model relates to the field of intelligent signboard transmission technology, and in particular to a vacuum adsorption flipping and transmission device for a large-size intelligent signboard. Background Technology

[0002] Large-size smart dashboards refer to smart touch display devices with screen sizes typically exceeding 65 inches. They integrate multiple functions such as high-definition display, infrared / capacitive touch, wireless projection, whiteboard writing, audio and video conferencing, and remote collaboration, and have become an important hardware carrier for promoting information technology and collaboration efficiency in smart offices, smart education, and industrial digital transformation.

[0003] Large-size intelligent signboards present significant challenges in production, installation, and maintenance due to their large size, heavy weight, and fragile surfaces. Ensuring safe and efficient handling, flipping, and positioning becomes a key technological challenge. Vacuum adsorption flipping and transfer technology has emerged to address this need. It utilizes the principle of vacuum negative pressure to generate adsorption force, which, combined with a flipping mechanism, enables stable handling and precise posture adjustment of the signboards. Currently, this technology has been applied in various industrial fields and has spawned numerous patented design solutions. Existing vacuum adsorption flipping devices typically consist of core components such as an adsorption module, a flipping mechanism, a support frame, and a transfer system. Taking a basic vacuum adsorption flipping device as an example, its typical structure includes a perforated plate, a flipping platform, a transfer platform, and a support frame. The perforated plate has multiple through-holes for air pressure balance along its thickness, while the flipping platform has air guide grooves and multiple air guide holes. When the perforated plate is placed on the flipping platform, the air pressure balance holes, air guide grooves, and air guide holes form interconnected air passages. Combined with a vacuum bag film, this creates an overall balanced vacuum, preventing damage to parts during flipping. In the field of wafer transfer, a wafer transfer flipping mechanism adopts a more sophisticated design, including a PLC, a rotary cylinder, a vacuum pneumatic chuck, a frame board, a displacement mechanism, and an adjustment mechanism. The adjustment mechanism includes components such as linear slide rails, electric lead screw slides, and telescopic cylinders, which can achieve more precise position control and complex motion trajectories.

[0004] Large-sized smart signboards may accidentally shift during initial transport, causing them to be out of position. This can lead to a shift in the center of gravity of the force point during vacuum adsorption and flipping, potentially damaging the signboard. The technical essence of this problem lies in the fact that even a slight positional deviation of the object during transport causes the adsorption point of the vacuum adsorption device to no longer match the center of gravity of the signboard, resulting in an asymmetrical force state. This generates additional torque and shear force during flipping, which can range from affecting positioning accuracy to causing damage to the surface or internal structure of the signboard.

[0005] Specifically in the field of vacuum adsorption flipping technology, the patented vacuum adsorption flipping table with application number 202422475712.0 also has a similar problem: its vacuum adsorption flipping head is fixed in position and cannot be adaptively adjusted according to the actual position of the signboard. When a large-size smart signboard experiences a slight shift during the initial transmission, the fixed adsorption head cannot compensate for this positional deviation, causing the force point to deviate from the center of gravity of the signboard during adsorption. This generates additional torque during the flipping process, which not only affects the flipping stability but also increases the risk of the signboard being damaged due to uneven force.

[0006] Therefore, in response to the problem that "large-size smart signboards may accidentally shift during the initial transmission, causing them to be out of their original position, which leads to a shift in the center of gravity during the vacuum adsorption and flipping process, making the large-size smart signboards prone to damage", a vacuum adsorption flipping and transmission device for large-size smart signboards is proposed. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The purpose of this utility model embodiment is to provide a vacuum adsorption flipping and transmission device for large-size smart signs, which aims to solve the problem that large-size smart signs may accidentally shift during the initial transmission and not be in their original position. This causes the force point to shift the center of gravity during the vacuum adsorption flipping process, making the large-size smart signs easily damaged.

[0009] (II) Technical Solution

[0010] Specifically: A vacuum adsorption flipping and transmission device for a large-size intelligent signboard includes a closed-loop guide rail assembly and multiple vacuum adsorption flipping components slidably mounted on the guide rail assembly. These multiple vacuum adsorption flipping components can move cyclically along the guide rail assembly. Each vacuum adsorption flipping component includes a drive head, a connecting plate, and a vacuum adsorption flipping component body. The vacuum adsorption flipping component body is mounted on the connecting plate, which is L-shaped and used to mount the vacuum adsorption flipping component body onto the drive head. The drive head is slidably mounted on the guide rail assembly to drive the vacuum adsorption flipping component body to move cyclically along the guide rail assembly. The vacuum adsorption flipping component body includes a vacuum adsorption flipping structure, which includes a multi-dimensional adjustment frame and a vacuum adsorption flipping head. The multi-dimensional adjustment frame is used to adjust the position of the vacuum adsorption flipping head in multiple dimensions to act on... On the large-size smart signboard; after the large-size smart signboard is conveyed to the bottom of the guide rail assembly, multiple vacuum adsorption flipping components at one end of the guide rail assembly will sequentially apply their bodies to the large-size smart signboard. During this process, the vacuum adsorption flipping components will activate the vacuum adsorption flipping structure. The vacuum adsorption flipping structure uses a multi-dimensional adjustment frame to adjust the position of the vacuum adsorption flipping head in multiple dimensions, so that the vacuum adsorption flipping head can accurately and stably apply its body to the center of gravity of the large-size smart signboard. This is to easily cope with any accidental displacement of the large-size smart signboard during the initial transmission, which may cause it to be out of its original position, and to avoid damage to the signboard due to the shift of the center of gravity during the vacuum adsorption flipping process. Finally, the drive head is used to drive the vacuum adsorption flipping components to move cyclically on the guide rail assembly, conveying the large-size smart signboard sequentially to the other end of the guide rail assembly for flipping.

[0011] The technical solution of this application will be further described below:

[0012] In one embodiment, the multidimensional adjustment frame includes a horizontal telescopic arm and a vertical telescopic arm. One end of the horizontal telescopic arm is connected to a drive motor, which can drive the horizontal telescopic arm to rotate on its horizontal surface after the drive motor outputs rotational power. The other end of the horizontal telescopic arm is attached to the vertical telescopic arm, which is perpendicular to the horizontal telescopic arm. The end of the vertical telescopic arm away from the horizontal telescopic arm is mounted on the vacuum adsorption flipping head.

[0013] Furthermore, the longitudinal telescopic arm and the transverse telescopic arm are assembled together through a positioning shell, with the longitudinal telescopic arm movably inserted and fixed on the positioning shell, and the end of the transverse telescopic arm fixed on the side wall of the positioning shell.

[0014] Furthermore, the end of the lateral telescopic arm away from the longitudinal telescopic arm is inserted and fitted onto the positioning sleeve, and the positioning sleeve is integrally fixed to the slide plate; a guide slider is fixed on the slide plate.

[0015] Furthermore, the guide slider is slidably mounted on the positioning plate, and a limit groove is formed on the positioning plate to match the guide slider. The limit groove is ring-shaped, and the guide slider is slidably mounted on the limit groove.

[0016] Furthermore, a rotating shaft is inserted along the column centerline of the positioning disk, and the rotating shaft is rotatably assembled with the positioning disk through a bearing ring; a fixing plate is fixed on the side wall of the positioning disk, the fixing plate is perpendicular to the positioning disk, and the end of the fixing plate away from the positioning disk is fixed to a connecting plate.

[0017] In one embodiment, the guide rail assembly includes a guide rail in the form of a closed loop, a frame fixed inside the guide rail, and mounting beams and columns assembled on the frame.

[0018] Furthermore, the drive head includes a drive platform with a slot, and the drive platform is slidably mounted on a guide rail through the slot. A rack is laid on the guide rail. A motor is installed inside the drive platform, and a drive gear is installed on the output shaft of the motor. The drive gear is located inside the slot and meshes with the rack.

[0019] (III) Beneficial Effects

[0020] Compared with existing technologies, the vacuum adsorption flipping and transmission device for large-size smart signboards of this utility model, after the large-size smart signboard is conveyed to the bottom of the guide rail assembly, multiple vacuum adsorption flipping components at one end of the guide rail assembly will sequentially apply their main bodies to the large-size smart signboard. During this process, the main bodies of the vacuum adsorption flipping components will activate the vacuum adsorption flipping structure. The vacuum adsorption flipping structure uses a multi-dimensional adjustment frame to adjust the position of the vacuum adsorption flipping head in multiple dimensions, so as to achieve precise and stable application of the vacuum adsorption flipping head to the center of gravity of the large-size smart signboard.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. The specific implementation of the present utility model will be described in detail below with reference to specific embodiments.

[0029] In this embodiment of the utility model, please refer to Figures 1-5 A vacuum adsorption flipping and transmission device for a large-size intelligent signboard includes a closed-loop guide rail assembly and multiple vacuum adsorption flipping components 4 slidably mounted on the guide rail assembly. The multiple vacuum adsorption flipping components 4 can move along the guide rail assembly and circulate on the guide rail assembly.

[0030] After the large-size smart signboard is conveyed to the bottom of the guide rail assembly, multiple vacuum adsorption flipping parts 4 at one end of the guide rail assembly will act on the large-size smart signboard in sequence, conveying the large-size smart signboard to the other end of the guide rail assembly and then flipping it.

[0031] To understand the vacuum adsorption flipping component 4 and its working principle in detail, the following description is provided: The vacuum adsorption flipping component 4 includes a driving head 5, a connecting plate 6, and a vacuum adsorption flipping component body 7. The vacuum adsorption flipping component body 7 is assembled on the connecting plate 6, which is L-shaped and used to assemble the vacuum adsorption flipping component body 7 onto the driving head 5. The driving head 5 is slidably assembled on the guide rail assembly and is used to drive the vacuum adsorption flipping component body 7 to move cyclically on the guide rail assembly.

[0032] Therefore, after the large-size smart signboard is conveyed to the bottom of the guide rail assembly, multiple vacuum adsorption flipping parts 4 at one end of the guide rail assembly will sequentially use the vacuum adsorption flipping part body 7 to act on the large-size smart signboard, start the drive head 5, and use the drive head 5 to drive the vacuum adsorption flipping part body 7 to move cyclically on the guide rail assembly, and then convey the large-size smart signboard to the other end of the guide rail assembly for flipping.

[0033] To understand in detail the vacuum adsorption flipping component body 7 and its working principle, the following description is provided: The vacuum adsorption flipping component body 7 includes a vacuum adsorption flipping structure 75, which includes a multi-dimensional adjustment frame and a vacuum adsorption flipping head 757. The multi-dimensional adjustment frame is used to adjust the position of the vacuum adsorption flipping head 757 in multiple dimensions to act on the large-size intelligent display board.

[0034] Therefore, after the large-size smart signboard is conveyed to the bottom of the guide rail assembly, multiple vacuum adsorption flipping components 4 at one end of the guide rail assembly will sequentially use the vacuum adsorption flipping component body 7 to act on the large-size smart signboard. During this process, the vacuum adsorption flipping component body 7 will activate the vacuum adsorption flipping structure 75. The vacuum adsorption flipping structure 75 uses a multi-dimensional adjustment frame to adjust the position of the vacuum adsorption flipping head 757 in multiple dimensions, so that the vacuum adsorption flipping head 757 can accurately and stably act on the center of gravity of the large-size smart signboard. This is to easily cope with the large-size smart signboard being accidentally offset during the initial transmission and thus not being in its original position, and to avoid damage to the signboard due to the offset of the center of gravity during the vacuum adsorption flipping process. Finally, the drive head 5 is used to drive the vacuum adsorption flipping component body 7 to move cyclically on the guide rail assembly, conveying the large-size smart signboard sequentially to the other end of the guide rail assembly for flipping.

[0035] In this embodiment of the utility model, please refer to Figures 3-5 The multi-dimensional adjustment frame includes a horizontal telescopic arm 754 and a vertical telescopic arm 755. One end of the horizontal telescopic arm 754 is connected to the drive motor 72, and can rotate on the horizontal surface of the horizontal telescopic arm 754 after the drive motor 72 outputs rotational power. The other end of the horizontal telescopic arm 754 is attached to the vertical telescopic arm 755. The vertical telescopic arm 755 and the horizontal telescopic arm 754 are perpendicularly distributed. The end of the vertical telescopic arm 755 away from the horizontal telescopic arm 754 is installed on the vacuum adsorption flipping head 757.

[0036] During the process of the vacuum adsorption flipping component 7 acting on the large-size smart signboard, the vacuum adsorption flipping component 7 activates the vacuum adsorption flipping structure 75. The vacuum adsorption flipping structure 75 uses the drive motor 72 on the multi-dimensional adjustment frame to drive the vacuum adsorption flipping head 757, the horizontal telescopic arm 754, and the vertical telescopic arm 755 to rotate on the horizontal plane. The horizontal telescopic arm 754 extends and retracts to adjust the rotation radius of the vacuum adsorption flipping head 757 and the vertical telescopic arm 755 on the horizontal plane. Then, the vertical telescopic arm 755 extends and retracts to adjust the position of the vacuum adsorption flipping head 757 in the vertical plane. This completes the multi-dimensional adjustment of the position of the vacuum adsorption flipping head 757, so that the vacuum adsorption flipping head 757 can be accurately and stably applied to the center of gravity of the large-size smart signboard. This is to easily cope with the situation where the large-size smart signboard is accidentally deviated during the initial transmission and is no longer in its original position, and to avoid the situation where the center of gravity shifts during the vacuum adsorption flipping process, causing damage to the signboard.

[0037] It should be noted that the vacuum adsorption flipping head 757, and the related technologies of vacuum adsorption and flipping on the vacuum adsorption flipping head 757 are existing technologies. Their detailed structures can be found in existing literature and journals, and they can also be purchased directly on the market, or components can be purchased on the market to assemble them, etc. They are not what this invention is meant to protect, and will not be described in detail here, nor are they shown in the accompanying drawings.
