Description
Technical Field
[0001] This utility model relates to the field of under-screen buffer film production and processing technology, specifically, to an under-screen buffer film production and processing device. Background Technology
[0002] An LCD screen uses liquid crystal material as its basic component. The liquid crystal material is filled between two parallel plates. By changing the arrangement of molecules inside the liquid crystal material through voltage, the screen can display images of varying shades and textures to achieve the purpose of blocking and transmitting light. During the installation process, a buffer film is generally used to protect the LCD screen.
[0003] However, the positioning accuracy of the buffer film during processing is insufficient, making it difficult to accurately fix the edges and key areas of the film. This leads to problems such as displacement and wrinkles in the subsequent die-casting process, directly affecting the product's dimensional consistency and appearance quality, ultimately resulting in a significant reduction in yield. Furthermore, the die-casting pressure lacks an effective control and monitoring mechanism, making it impossible to accurately match the die-casting pressure parameters according to the requirements of buffer films of different specifications and thicknesses. Excessive pressure can easily lead to damage to the film structure and deterioration of performance, while insufficient pressure makes it difficult to achieve the expected die-casting effect, thus affecting the buffering performance and service life of the buffer film. Therefore, those skilled in the art provide an under-screen buffer film production and processing device to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this utility model is to provide a production and processing device for under-screen buffer film, which solves the problems mentioned in the background art of the prior art.
[0005] This utility model provides the following technical solution: a production and processing device for under-screen buffer film, including four sets of support legs for supporting the upper part, and a positioning mechanism for positioning the buffer film at the upper end of the four sets of symmetrically arranged support legs, and a die-casting mechanism for die-casting the positioned buffer film at the upper end of the positioning mechanism.
[0006] As a preferred embodiment of the above technical solution, the positioning mechanism includes a base plate, which is fixedly connected to the upper end of four symmetrically arranged support legs. Four symmetrically arranged first cylinders are fixedly connected to the center of the upper end of the base plate near the edge. One end of each first cylinder is fixedly connected to a fixed seat. The inner cavity of the center of the base plate is provided with a hollow groove for easy observation of the die-casting state.
[0007] As a preferred embodiment of the above technical solution, the output end of the first cylinder is fixedly connected to a sliding plate that penetrates the inner cavity of the fixed seat. The upper end of the sliding plate on the side away from the output end of the first cylinder is fixedly connected to two sets of symmetrically arranged connecting columns. A positioning gripper is hinged to one side of the two sets of symmetrically arranged connecting columns. A connecting rod is rotatably connected to the inner cavity of the positioning gripper on the side away from the connecting column. The positioning gripper is rotatably connected to the side of the fixed seat away from the output end of the first cylinder through the connecting rod.
[0008] As a preferred embodiment of the above technical solution, the die-casting mechanism includes a fixed column, which is fixedly connected to the side end of the base plate. A top plate is fixedly connected to the upper end of the fixed column. A cylinder seat is fixedly connected to one side of the upper center of the top plate. A second cylinder is fixedly connected to one side of the cylinder seat, and the second cylinder is fixedly connected to the center of the upper center of the top plate.
[0009] As a preferred embodiment of the above technical solution, a bushing is fixedly connected to the center of the lower end of the top plate, and a telescopic rod that passes through the inner cavity of the top plate is slidably connected to the inner cavity of the bushing. The upper end of the telescopic rod is fixedly connected to the output end of the second cylinder, and a hydraulic controller is fixedly connected to the bottom end of the telescopic rod.
[0010] As a preferred embodiment of the above technical solution, a pressure sensor is fixedly connected to the bottom of the hydraulic controller, and a die-casting head is fixedly connected to the bottom of the pressure sensor, with the die-casting head positioned directly above the hollowed-out groove.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention features a die-casting mechanism. A stable frame is constructed by connecting a fixed column to the base plate and a top plate to the fixed column. Combined with the double fixation of the second cylinder by the cylinder seat and the top plate, the overall structure remains stable during die-casting, preventing component misalignment from affecting processing accuracy. The bushing at the lower end of the top plate provides vertical sliding guidance for the telescopic rod, ensuring that the telescopic rod drives subsequent components to move along a precise trajectory, further improving the accuracy of the die-casting position. The hydraulic controller at the bottom of the telescopic rod can flexibly adjust the die-casting pressure, and with the pressure sensor monitoring the pressure data in real time, it can effectively prevent excessive pressure from damaging the buffer film or insufficient pressure from causing substandard processing, ensuring product processing quality. At the same time, the die-casting head is designed with a corresponding hollow groove in the base plate, which not only facilitates the observation of the die-casting status by the operator, allowing for timely detection and handling of processing problems, but also ensures precise alignment between the die-casting head and the positioned film.
[0012] Based on the aforementioned beneficial effects, this utility model is equipped with a positioning mechanism. Four sets of symmetrical support legs stably support the base plate, providing a solid foundation for the entire positioning operation and preventing positioning accuracy from being affected by unstable support. Four sets of first cylinders symmetrically arranged at the upper part of the base plate can synchronously drive the corresponding parts to move. Together with the fixed seat to limit the sliding plate, the sliding plate can be ensured to slide smoothly. Then, the positioning claw is driven by the connecting column. With the guidance and limiting effect of the connecting rod, the positioning claw can achieve symmetrical and uniform clamping and positioning of the buffer film, effectively preventing the film from shifting during the subsequent die casting process and ensuring accurate processing position. At the same time, the hollow groove opened in the center of the base plate makes it convenient for the staff to observe the state of the film during die casting in real time.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] Please see Figures 1-5 As shown, this utility model provides a technical solution: a production and processing device for under-screen buffer film, including four sets of support legs 1 for supporting the upper part, and a positioning mechanism 2 for positioning the buffer film at the upper end of the four sets of symmetrically arranged support legs 1, and a die-casting mechanism 3 for die-casting the positioned buffer film at the upper end of the positioning mechanism 2.
[0017] Four sets of symmetrical support legs 1 stably support the overall structure. After the positioning mechanism 2 is activated, the four sets of symmetrical first cylinders 22 on the base plate 21 push the slide plate 24 connected to the output end to slide in the inner cavity of the fixed seat 23. The slide plate 24 drives the positioning claw 26 to move through the connecting column 25. At the same time, the positioning claw 26 adjusts its angle with the help of the connecting rod 27 rotatably connected to the fixed seat 23, thereby accurately clamping and positioning the buffer film. After positioning is completed, the die-casting mechanism 3 starts to work. The second cylinder 34 fixed by the cylinder seat 33 on the top plate 32 drives the telescopic rod 36 connected to the output end to move downward under the guidance of the bushing 35. The hydraulic controller 37 at the bottom of the telescopic rod 36 regulates the pressure, and the pressure sensor 38 at the bottom monitors the pressure value in real time. Finally, the die-casting head 39 drives the positioned buffer film to be accurately die-cast above the hollow groove 28 in the center of the base plate 21.
[0018] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the positioning mechanism 2 includes a base plate 21, which is fixedly connected to the upper end of four sets of symmetrically arranged support legs 1. Four sets of symmetrically arranged first cylinders 22 are fixedly connected to the center of the upper end of the base plate 21 near the edge. One end of the first cylinder 22 is fixedly connected to a fixed seat 23. The inner cavity of the center of the base plate 21 is provided with a hollow groove 28 for easy observation of the die-casting state.
[0019] Four sets of symmetrically arranged support legs 1 provide stable support for the upper base plate 21. The base plate 21 serves as the basic load-bearing component of the positioning mechanism 2. Four sets of symmetrical first cylinders 22 fixed at the center of the upper end near the edge provide power for the positioning action. The fixed seat 23 connected to one end of the first cylinder 22 provides the installation and limiting basis for the subsequent positioning components. When it is necessary to position the buffer film, the first cylinder 22 is activated, and its output end drives the relevant components to work together to achieve clamping and positioning of the buffer film. At the same time, the hollow groove 28 opened in the center of the base plate 21 allows the staff to easily observe the die-casting state of the buffer film during the subsequent die-casting process, ensuring that the positioned film can accurately cooperate with the die-casting mechanism 3 to complete the processing.
[0020] As one implementation method in this embodiment, please refer to Figures 2-4 As shown, a slide plate 24 that passes through the inner cavity of the fixed seat 23 is fixedly connected to the output end of the first cylinder 22. Two sets of symmetrically arranged connecting columns 25 are fixedly connected to the upper end of the slide plate 24 on the side away from the output end of the first cylinder 22. A positioning gripper 26 is hinged to one side of the two sets of symmetrically arranged connecting columns 25. A connecting rod 27 is rotatably connected to the inner cavity of the end of the positioning gripper 26 away from the connecting column 25. The positioning gripper 26 is rotatably connected to the side of the fixed seat 23 away from the output end of the first cylinder 22 through the connecting rod 27.
[0021] The output end of the first cylinder 22 drives the slide plate 24, which is fixedly connected to it, to slide linearly within the cavity of the fixed seat 23. As the slide plate 24 moves away from the output end of the first cylinder 22, the two sets of connecting columns 25 symmetrically fixed at the upper end of the slide plate 24 move synchronously. Since the connecting columns 25 are hinged to the positioning claws 26, the movement of the connecting columns 25 will drive the positioning claws 26 to rotate. At the same time, the end of the positioning claws 26 away from the connecting columns 25 is rotatably connected to the side of the fixed seat 23 away from the output end of the first cylinder 22 through the connecting rod 27. The connecting rod 27 limits and guides the rotation of the positioning claws 26, ultimately enabling the positioning claws 26 to cooperate with each other to achieve stable clamping and positioning of the under-screen buffer film.
[0022] As one implementation method in this embodiment, please refer to Figures 1-5 As shown, the die-casting mechanism 3 includes a fixed column 31, which is fixedly connected to the side of the base plate 21. The upper end of the fixed column 31 is fixedly connected to a top plate 32. A cylinder seat 33 is fixedly connected to one side of the upper center of the top plate 32. A second cylinder 34 is fixedly connected to one side of the cylinder seat 33, and the second cylinder 34 is fixedly connected to the center of the upper end of the top plate 32.
[0023] One end of the fixed column 31 is fixedly connected to the side of the base plate 21 of the positioning mechanism 2, and the other end extends upward and is fixed to the top plate 32, thereby building a stable frame for the die-casting mechanism 3 and providing a bearing foundation for subsequent die-casting operations. The top plate 32 serves as the mounting carrier for the second cylinder 34. The cylinder seat 33 on one side of its upper center, together with the center of the top plate 32, provides a double fixing effect for the second cylinder 34, ensuring that the second cylinder 34 is stable in position and does not shift during operation. When it is necessary to die-cast the positioned buffer film, the second cylinder 34 is started as a power source. Its output end can drive the subsequent connected telescopic rod 36, hydraulic controller 37, die-casting head 39 and other components to work together, providing a downward driving force for the die-casting head 39, thereby realizing the die-casting process of the buffer film.
[0024] As one implementation method in this embodiment, please refer to Figures 2-5 As shown, a bushing 35 is fixedly connected to the center of the lower end of the top plate 32. A telescopic rod 36 that passes through the inner cavity of the top plate 32 is slidably connected to the inner cavity of the bushing 35. The upper end of the telescopic rod 36 is fixedly connected to the output end of the second cylinder 34, and the lower end of the telescopic rod 36 is fixedly connected to a hydraulic controller 37.
[0025] The bushing 35 fixed at the lower center of the top plate 32 provides a sliding guide base for the telescopic rod 36. The telescopic rod 36 passes through the central cavity of the top plate 32 and is slidably connected to the inner cavity of the bushing 35, ensuring that the telescopic rod 36 can only move stably in the vertical direction and avoid deviation. When the second cylinder 34 is started, its output end drives the telescopic rod 36, which is fixed to it, to slide downward or upward along the inner cavity of the bushing 35, realizing the vertical displacement transmission. At the same time, the hydraulic controller 37 fixed at the bottom of the telescopic rod 36 moves synchronously with the telescopic rod 36. The pressure can be adjusted through the hydraulic controller 37 to provide a suitable die-casting pressure for the die-casting head 39 below, thereby completing the precise die-casting process of the positioning buffer film.
[0026] As one implementation method in this embodiment, please refer to Figures 2-5 As shown, a pressure sensor 38 is fixedly connected to the bottom of the hydraulic controller 37, and a die-casting head 39 is fixedly connected to the bottom of the pressure sensor 38, with the die-casting head 39 positioned directly above the hollowed-out groove 28.
[0027] The pressure sensor 38 fixed at the bottom of the hydraulic controller 37 monitors the pressure data generated when the die-casting head 39 contacts the buffer film in real time during the die-casting process. This ensures that the die-casting pressure meets the processing requirements and avoids damage to the film due to excessive pressure or substandard processing due to insufficient pressure. The die-casting head 39, fixed at the bottom of the pressure sensor 38, can apply precise pressure to the buffer film fixed on the positioning mechanism 2 under the combined action of the second cylinder 34 transmitting power through the telescopic rod 36 and the hydraulic controller 37 adjusting the pressure, thus completing the die-casting process. At the same time, the die-casting head 39 is set directly above the central hollow groove 28 of the base plate 21, which not only ensures the precise correspondence between the die-casting position and the buffer film, but also makes it easy for the staff to observe the working status of the die-casting head 39 through the hollow groove 28.
[0028] Working principle: Four sets of symmetrical support legs 1 stably support the upper positioning mechanism 2. The base plate 21 of the positioning mechanism 2 serves as the basic component. After the four sets of symmetrical first cylinders 22 at its upper end are activated, they push the slide plate 24 to slide within the cavity of the fixed seat 23. The slide plate 24 drives the positioning claw 26 through the connecting column 25. With the limiting guidance of the connecting rod 27, the positioning claw 26 accurately clamps and positions the buffer film under the screen. At the same time, the hollow groove 28 in the center of the base plate 21 facilitates subsequent observation of the die-casting state. The die-casting mechanism 3 is connected to the side of the base plate 21 through the fixed column 31. The top plate 32 at the upper end of the fixed column 31 provides the mounting base for the second cylinder 34. The cylinder seat 33 and the top plate 32 together fix the second cylinder 34 to ensure its stability. During die casting, the second cylinder 34 drives the telescopic rod 36 to slide vertically along the bushing 35 at the lower end of the top plate 32. The hydraulic controller 37 at the bottom of the telescopic rod 36 adjusts the pressure, and the pressure sensor 38 monitors the die casting pressure in real time to ensure that the pressure meets the requirements. Finally, the die casting head 39, which is connected to the pressure sensor 38 and located directly above the hollow groove 28, applies precise pressure to the positioned buffer film to complete the die casting process.
[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
