Abstract
Description
Technical Field
[0001] This invention relates to the field of display screen processing equipment technology, and more specifically, to a folding screen processing clamping device. Background Technology
[0002] As a highly precise flexible display device, foldable screens place extremely stringent requirements on the clamping and fixing process during manufacturing. The screen itself is ultra-thin, easily bent, and has a fragile surface; any improper clamping force or localized stress concentration can easily cause irreversible damage to its internal microstructure, such as creases, cracks, or coating peeling, severely impacting product yield.
[0003] Currently, the clamping equipment widely used in the bonding, gluing, testing, and assembly processes of foldable screens generally suffers from the following systemic defects, which severely restrict the improvement of processing efficiency and precision: Most existing clamping fixtures completely lock the screen in a single position and angle. When the process requires a change in the processing orientation (for example, a foldable screen needs to be folded at a certain angle), the operator must completely disassemble the screen, manually adjust its posture, and then reposition and clamp it. This process not only greatly reduces production efficiency and breaks the continuity of operations, but more fatally, each re-clamping introduces new positioning errors. The accumulation of these errors will directly lead to the final product's accuracy exceeding the standard.
[0004] Secondly, most equipment uses simple mechanical clamps or bolts to directly fasten the screen, and the clamping surface and the screen are only in rigid contact. This method cannot adapt to the slight thickness differences or curved features of different screen models, which can easily cause excessive local pressure. More importantly, once clamped, it cannot be fine-tuned. If there is a deviation in the initial position or the screen undergoes slight deformation due to factors such as temperature, there is no effective means of compensation, which directly damages the processing quality.
[0005] Third, existing market solutions often distribute functions such as clamping, horizontal rotation, and angle flipping across different workstations or different mechanisms. This forces multiple manual transfers and repetitive positioning in the production process, which not only increases the risk of the screen being scratched or impacted during the transfer process, but also makes it difficult for the entire production line to achieve flexibility and automation, and fails to meet the needs of modern intelligent manufacturing for "one machine with multiple functions" and rapid production changeover. Summary of the Invention
[0006] Technical problems to be solved To address the problems existing in the prior art, this invention provides a foldable screen processing clamping device to solve the problem mentioned in the background art, where most existing clamping fixtures completely lock the screen in a single position and angle. When the process requires a change in processing orientation (for example, when a foldable screen needs to be folded at a certain angle), the operator must completely disassemble the screen, manually adjust its posture, and then reposition and clamp it. This process not only greatly reduces production efficiency and disrupts the continuity of operations, but more critically, each re-clamping introduces new positioning errors. The accumulation of these errors directly leads to the technical problem of the final product's accuracy exceeding the standard.
[0007] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a folding screen processing clamping device, comprising a worktable, a direction adjustment structure provided on the worktable, a clamping structure and an angle adjustment structure provided on the direction adjustment structure, the direction adjustment structure comprising a first gear and a processing table, a first motor provided on one side of the worktable, the output end of the first motor passing through the worktable and connected to the first gear, a rotating rod provided on the worktable, a support platform provided on the rotating rod and connected to the processing table, a second gear provided on the rotating rod and meshing with the tooth surface of the first gear, the clamping structure comprising a first clamping platform and a second clamping platform, four sets of first pillars and four sets of second pillars provided on the processing table, the first clamping platform being connected to two sets of first pillars and two sets of second pillars, the second clamping platform being in close contact with two sets of first pillars and two sets of second pillars, a hinge structure provided between the first clamping platform and the second clamping platform, and a clamping structure, a positioning structure and a height adjustment structure provided on the first clamping platform and the second clamping platform.
[0008] The present invention is further configured such that the hinge structure includes four sets of guide sliders and hinge rods, three sets of first hinges are provided on the first clamping platform, two sets of second hinge sleeves are provided on the second clamping platform with their inner walls respectively connected to the four sets of guide sliders, two sets of fixing plates are provided on one side of the first clamping platform, and the hinge rod is provided with a guide groove that slides with the eight sets of guide sliders, and the hinge rod slides through the two sets of first hinge sleeves and the three sets of second hinge sleeves; The guide groove on the hinge rod precisely slides in conjunction with eight sets of guide sliders installed on the first and second hinge sleeves respectively. This constraint design of multiple sliders in the long groove provides an extremely stable and precise axis of rotation for the flipping motion of the second clamping table.
[0009] The present invention is further configured such that the height adjustment structure includes four sets of first threaded rods and four sets of lifting plates, and a support plate is provided on one side of the first clamping platform and the second clamping platform respectively. The four sets of first threaded rods are threaded through the support plate and rotatably connected to the lifting plate. A friction pad is provided on one side of each of the four sets of lifting plates, and two guide plates are provided on one side of each of the four sets of lifting plates. The height adjustment mechanism allows the operator to independently rotate the four sets of first threaded rods, thereby precisely controlling the vertical height of each of the four lifting plates and their friction pads. Guide plates ensure the stability of the lifting movement.
[0010] The present invention is further configured such that the positioning structure includes four sets of sliding rods, four sets of first mounting plates are respectively provided on one side of the first clamping platform and the second clamping platform, the four sets of sliding rods are respectively provided between the two sets of first mounting plates, the four sets of sliding rods are respectively provided with top plates of sliding sleeves, and the four sets of sliding rods are respectively provided with springs. The positioning structure uses the elastic force of springs to push the top plate to slide along the slide bar. When placing the screen, the four sets of top plates can provide flexible and resilient limiting and centering from the side of the screen to achieve rapid pre-positioning.
[0011] The present invention is further configured such that the clamping structure includes four sets of second mounting plates, the first clamping platform and the second clamping platform are respectively connected to the four sets of second mounting plates, one of the two sets of adjacent second mounting plates is provided with a second threaded rod that is rotatably connected to and rotatably passes through the other set of mounting plates, and the four sets of second threaded rods are respectively provided with threaded clamping plates. The four clamping plates are driven by four independent second threaded rods, allowing the operator to fine-tune the clamping force and position of each side individually, thus achieving uniform and parallel clamping of the four edges of the screen.
[0012] The present invention is further configured such that one end of each of the four sets of first threaded rods and the four sets of second threaded rods is provided with a friction wheel; Friction wheels are installed at the ends of the first and second threaded rods, providing the operator with an intuitive and convenient manual operation interface. By rotating the friction wheels, the support height and clamping tightness can be easily and finely adjusted.
[0013] The present invention is further configured such that the angle adjustment structure includes a second motor and a third gear, a connecting plate for mounting the second motor is provided on one side of the processing table, the output end of the second motor rotates through the connecting plate and connects to the third gear, and a fourth gear is provided on the hinge rod to mesh with the tooth surface of the third gear; The second motor drives the third gear to mesh with the fourth gear fixed on the hinge rod, providing power for the bending and flipping of the screen. This structure integrates the drive source directly into the processing table, resulting in a short transmission path and precise control.
[0014] The present invention is further configured such that a protective cover is provided on the workbench, and the rotating rod passes through the protective cover; A protective cover is installed on the workbench to encapsulate and protect the rotating rod and its transmission components, such as the second gear.
[0015] (III) Beneficial Effects Compared with the prior art, the present invention has the following beneficial effects: 1. This invention innovatively integrates a direction adjustment structure and an angle adjustment structure. The direction adjustment structure, driven by a motor and gear transmission, enables the entire processing table, along with the clamped screen, to rotate continuously 360° in the horizontal plane, facilitating processing or inspection from different angles. The angle adjustment structure, driven by another set of motors and gears, rotates the hinge rod, thereby driving the second clamping table to achieve precise angle flipping around the hinge axis (e.g., simulating the bending state of a folding screen). All posture adjustments can be completed in place after the screen is clamped once, without disassembly or repositioning. This not only greatly improves the continuity of the process and eliminates the cumulative errors introduced by repeated clamping, ensuring the uniqueness of the processing benchmark and the high precision of the final product, but also significantly improves production efficiency. 2. This invention, through a positioning structure composed of a slide bar, a spring, and a top plate, can flexibly pre-position a folding screen placed in the working area, allowing for slight positional tolerances when the screen is initially placed. Combined with a clamping structure composed of a second threaded rod and a clamping plate, it achieves parallel and uniform force clamping of the screen's four edges. The height adjustment structure, by independently adjusting the four sets of first threaded rods, can precisely control the support height of the four sets of friction pads, thereby actively adapting to the thickness differences, edge curvature, or slight deformations of different screen models, lifting and fixing the screen flat and stress-free in the ideal position, completely avoiding excessive local pressure and stress concentration caused by traditional rigid clamping, and fundamentally protecting the screen's microstructure. 3. This invention highly integrates the core functions of clamping and fixing, horizontal rotation, angle flipping, and adaptive leveling into a compact equipment platform, achieving "one machine with multiple functions". The modular design allows the clamping structure to adapt to folding screens of different sizes and specifications. Operators can manually fine-tune the clamping and support by rotating the exposed friction wheels, facilitating quick production changes. The protective cover enhances equipment safety. This integrated and flexible design greatly reduces material turnover and equipment switching between different processes, and reduces the risk of screen damage during the transfer process.

[0021] Please see Figure 1-5A folding screen processing clamping device includes a worktable 1, on which a direction adjustment structure is provided. The direction adjustment structure includes a clamping structure and an angle adjustment structure. The direction adjustment structure includes a first gear 2 and a processing table 3. A first motor 4 is provided on one side of the worktable 1, and the output end of the first motor 4 passes through the worktable 1 and connects to the first gear 2. A rotating rod 5 is rotatably connected to the worktable 1, and a support platform 6 connected to the processing table 3 is provided on the rotating rod 5. A gear tooth is provided on the rotating rod 5 that meshes with the first gear 2. The second gear 7 is engaged with the surface. The clamping structure includes a first clamping platform 8 and a second clamping platform 9. The processing table 3 is provided with four sets of first support columns 10 and four sets of second support columns 11. The first clamping platform 8 is connected to two sets of first support columns 10 and two sets of second support columns 11. The second clamping platform 9 is in close contact with two sets of first support columns 10 and two sets of second support columns 11. A hinge structure is provided between the first clamping platform 8 and the second clamping platform 9. The first clamping platform 8 and the second clamping platform 9 are provided with a clamping structure, a positioning structure and a height adjustment structure.
[0022] In this embodiment, the hinge structure includes four sets of guide sliders 12 and hinge rods 13. The first clamping platform 8 is provided with three sets of first hinges 14. The second clamping platform 9 is provided with two sets of second hinge sleeves 15 whose inner walls are respectively connected to the four sets of guide sliders 12. Two sets of fixing plates 16 are provided on one side of the first clamping platform 8. The hinge rod 13 is provided with guide grooves 17 that slide and fit with the eight sets of guide sliders 12. The hinge rod 13 slides through the three sets of first hinges 14 and the two sets of second hinge sleeves 15. The guide groove 17 on the hinge rod 13 precisely slides with eight sets of guide sliders 12 respectively installed on the first hinge sleeve 14 and the second hinge sleeve 15. This constraint design of multiple sliders in the long groove provides an extremely stable and precise axis of rotation for the flipping motion of the second clamping table 9. It not only ensures the smoothness and linearity of the flipping action, but also effectively resists the lateral force and torque generated during the flipping process, and reliably transmits the force to the first support column 10 and the second support column 11, ensuring the structural rigidity and positional accuracy of the entire clamping system during dynamic adjustment.
[0023] In this embodiment, the height adjustment structure includes four sets of first threaded rods 18 and four sets of lifting plates 19. Support plates 20 are respectively provided on one side of the first clamping platform 8 and the second clamping platform 9. The four sets of first threaded rods 18 are threaded through the support plates 20 and rotatably connected to the lifting plates 19. Friction pads 21 are respectively provided on one side of the four sets of lifting plates 19. Two sets of guide plates 22 are respectively provided on one side of the four sets of lifting plates 19. The height adjustment structure allows the operator to independently rotate the four sets of first threaded rods 18, thereby precisely controlling the vertical height of the four sets of lifting plates 19 and their friction pads 21. The guide plate 22 ensures the stability of the lifting movement. This design enables the equipment to actively adapt to the slight thickness differences, edge curvature designs, or slight overall deformation that may exist in different models and batches of folding screens, lifting the screen flat without warping or local stress, laying an ideal foundation for subsequent precise clamping and processing, and effectively preventing internal damage to the screen caused by uneven support.
[0024] In this embodiment, the positioning structure includes four sets of slide rods 23. Four sets of first mounting plates 24 are respectively provided on one side of the first clamping platform 8 and the second clamping platform 9. The four sets of slide rods 23 are respectively arranged between the two sets of first mounting plates 24. The four sets of slide rods 23 are respectively provided with top plates 25 of sliding sleeves. The four sets of slide rods 23 are respectively provided with springs 26. The positioning structure utilizes the elastic force of spring 26 to push the top plate 25 to slide along the slide bar 23. When placing the screen, the four sets of top plates 25 can provide flexible, resilient limiting and centering from the sides of the screen, achieving rapid pre-positioning. More importantly, this structure can absorb minor vibrations that may occur during equipment operation or in the external environment, and provide tolerance space for minor dimensional changes in the screen caused by temperature variations. It avoids the squeezing or constraint stress that may be caused by rigid positioning, and plays a positive role in buffering and protecting the screen.
[0025] In this embodiment, the clamping structure includes four sets of second mounting plates 27. The first clamping platform 8 and the second clamping platform 9 are respectively connected to the four sets of second mounting plates 27. One set of the two adjacent sets of second mounting plates 27 is provided with a second threaded rod 28 that is rotatably connected to and rotatably passes through the other set of mounting plates. The four sets of second threaded rods 28 are respectively provided with clamping plates 29 that are threadedly connected. The four clamping plates 29 are driven to move by four sets of independent second threaded rods 28. The operator can fine-tune the clamping force and position of each side individually to achieve uniform and parallel clamping of the four edges of the screen. This design avoids the risk of excessive force on a single point or side and ensures that the clamping force is evenly distributed in the frame area of the screen that can withstand force. While providing a firm fixation, it minimizes any potential pressure or deformation impact on the fragile display area of the screen body.
[0026] In this embodiment, one end of each of the four sets of first threaded rods 18 and the four sets of second threaded rods 28 is provided with a friction wheel 30; Friction wheels 30 are provided at the ends of the first threaded rod 18 and the second threaded rod 28, providing operators with an intuitive and convenient manual operation interface. By rotating the friction wheel 30, the support height and clamping tightness can be easily and finely adjusted. This design not only facilitates the quick setup and production changeover of the equipment, but also retains the ability to manually and precisely control key parameters in addition to the automated motor drive, thereby improving the human-machine interaction friendliness and process adaptability of the equipment.
[0027] In this embodiment, the angle adjustment structure includes a second motor 31 and a third gear 32. A connecting plate 33 for mounting the second motor 31 is provided on one side of the processing table 3. The output end of the second motor 31 rotates through the connecting plate 33 and connects with the third gear 32. A fourth gear 34 that meshes with the tooth surface of the third gear 32 is provided on the hinge rod 13. The second motor 31 drives the third gear 32 to mesh with the fourth gear 34 fixed on the hinge rod 13, providing power for the bending and flipping of the screen. This structure directly integrates the drive source into the processing table 3, with a short transmission path and precise control. The motor drive method allows for digital programming and precise control of the flipping angle, realizing automatic and repeatable positioning of specific bending angles of the folding screen (such as different curvature radii for testing), meeting the needs of high-precision and automated processing.
[0028] In this embodiment, a protective cover 35 is provided on the workbench 1, and the rotating rod 5 passes through the protective cover 35; A protective cover 35 is installed on the workbench 1 to enclose and protect the rotating rod 5 and its transmission components such as the second gear 7. This design can effectively isolate dust, debris and possible liquid splashes generated during the processing, prevent them from contaminating or damaging the precision transmission components, and significantly reduce the equipment failure rate.
[0029] In summary, when using the overall equipment... When clamping the folding screen, the height of the four lifting plates 19 is adjusted by rotating the friction wheels 30 on the four sets of first threaded rods 18 according to the thickness of the folding screen. This allows the folding screen placed on the four sets of lifting plates 19 to reach a suitable height for processing. Then, the four sets of top plates 25 are pushed to both sides to position and clamp the folding screen. During clamping, the four sets of springs 26 provide flexible clamping and positioning for the folding screen. Afterward, the friction wheels 30 on the four sets of second threaded rods 28 are rotated to drive the second threaded rods 28 to rotate and drive the clamping plates 29 to clamp the side of the folding screen. Since the four sets of clamping plates 29 only tightly clamp the edge of the folding screen, it ensures that when the angle of the screen on one side is adjusted, the folding screen can make slight positional changes on the clamping platform on one side in conjunction with the two sets of springs 26 and the two sets of top plates 25, preventing the folding screen from breaking due to rigid clamping. When adjusting the orientation of the folding screen and the angle of one side of the folding screen, the first motor 4 is activated. The first motor 4 drives the first gear 2 and the second gear 7 to rotate. During rotation, the rotating rod 5 drives the support platform 6 and the processing platform 3, as well as the first clamping platform 8 and the second clamping platform 9 on one side, to rotate, thereby adjusting the angle of the folding screen. When adjusting the angle of one side of the folding screen, the second motor 31 is activated. The second motor 31 drives the third gear 32 and the fourth gear 34 to rotate. During rotation, the hinge rod 13 drives the second clamping platform 9, which is fitted with a sliding block and a sliding groove, to adjust its upward angle. This allows the operator to fold the screen to a specific angle for processing. During adjustment, the two sets of top plates on the second clamping platform 9 also adjust their positions according to the change in the angle of the folding screen to prevent the screen from breaking.
[0030] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
