Description

Technical Field

[0001] This utility model relates to the field of prototyping machine technology, specifically to a high-speed prototyping machine for optical films. Background Technology

[0002] As a core component of high-end optical products such as display panels, camera modules, and photovoltaic modules, the processing precision of optical films directly determines the optical performance and user experience of the end products. During the product development and small-batch trial production stages, it is necessary to quickly output samples through prototyping machines to verify the size adaptability, pattern integrity, and optical characteristics of the films. Therefore, the processing precision and sample qualification rate of prototyping machines have become key factors affecting R&D efficiency.

[0003] Currently, most optical film prototyping machines on the market, in pursuit of high-speed prototyping, use an open worktable to transport the film without a dedicated fixing device at the bottom. They rely solely on the film's own weight or simple edge restraint for initial positioning. This positioning method is prone to film displacement due to multiple factors during blade cutting, leading to cutting failure.

[0004] The drive motor and motion guide rail of the high-speed prototyping machine will generate continuous vibration during high-frequency operation. Since the diaphragm and the worktable lack rigid fixation, the vibration energy will be transmitted to the diaphragm and cause micro-displacement. For high-precision diaphragms containing micro-apertures with diameters <1mm and complex curves, this micro-displacement will directly lead to pattern distortion, making the sample unable to meet the mass production precision standards.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0025] 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.

[0026] Please see Figures 1-4 This utility model provides a technical solution: a high-speed optical film prototyping machine, including a body 1, with an installation groove 11 formed at the bottom of the inner wall of the body 1. A drive mechanism 9 is fixedly installed at the bottom of the inner wall of the installation groove 11. Two fixing mechanisms 8 are engaged at both ends of the drive mechanism 9 and are respectively fixedly installed on both sides of the inner wall of the installation groove 11. The fixing mechanism 8 includes a fixing plate 88 fixedly installed on the side wall of the installation groove 11. Clamping arms 1 85 and 2 86 are rotatably installed on the inner walls of both ends of the fixing plate 88. The bottom of clamping arms 1 85 and 2 86 are rotatably mounted. The slide plate 81 is equipped with a sliding plate 81. The side wall of the sliding plate 81 is slidably connected to the inner wall of the mounting groove 11. A threaded post 83 is threadedly connected to the inner wall of the sliding plate 81. A bevel gear 82 is fixedly installed at the bottom of the threaded post 83. The outer wall of the bevel gear 82 meshes with the outer wall of the drive mechanism 9. The drive mechanism 9 drives the bevel gear 82 to rotate, which in turn causes the threaded post 83 to rotate, driving the sliding plate 81 to slide on the inner wall of the mounting groove 11. A spring 84 is fixedly connected to the top of the sliding plate 81. The top of the spring 84 is fixedly connected to the bottom of the fixed plate 88. The spring 84 is sleeved on the outer wall of the threaded post 83. For resetting, an extension rod 863 is fixedly installed on the outer wall of the rotating shaft 864. A connecting rod 865 is fixedly installed on the side end of the extension rod 863. A fixing rod 87 is threadedly connected to the side end of the connecting rod 865 via a screw. This adjustable connection method allows the position of the fixing rod 87 to be flexibly adjusted according to the width of the optical film. Furthermore, the movement of the slide plate 81 drives the clamping arms 85 and 86 to rotate around the rotating shaft 864, enabling the fixing rod 87 to accurately approach and press down on the optical film on the conveyor belt 3. This precise mechanical transmission method can achieve precise control of the optical film. Precise positioning and clamping ensure that the film is fixed in position during the prototyping process and will not shift, thereby improving the accuracy of prototyping and the quality of the sample. Since clamping arms 1 85 and clamping arms 2 86 are symmetrically distributed at both ends of the fixing plate 88 and achieve synchronous movement through the linkage of sliding plate 81 and threaded post 83, when clamping the optical film, the fixing rod 87 can apply pressure to the film from both sides evenly. This uniform force application method can avoid deformation or damage to the film due to excessive local pressure, and at the same time ensure that the film is subjected to stable constraint force throughout the clamping area.

[0027] Please see Figures 1-4This utility model provides a technical solution: a high-speed optical film prototyping machine, including a clamping arm 1 85 and a clamping arm 2 86, each including a short rod 861 rotatably connected to the top of a fixed plate 88. A long rod 862 is rotatably mounted at the end of the short rod 861, and a rotating shaft 864 is fixedly mounted at the end of the long rod 862. The rotating shaft 864 is fixed to the end of the long rod 862, providing a stable rotation center for the entire clamping arm structure. When the drive mechanism 9 drives the slide plate 81 to slide, thereby causing the clamping arm 1 85 and clamping arm 2 86 to rotate, the rotating shaft 864 can ensure smooth and unobstructed rotation between the long rod 862 and the short rod 861, reducing jamming and friction in the mechanical transmission process, and improving the working efficiency and reliability of the entire clamping system.

[0028] Please see Figures 1-4 This utility model provides a technical solution: a high-speed optical film prototyping machine, including a drive mechanism 9 comprising a base plate 91 fixedly connected to the bottom of the inner wall of a mounting groove 11, support plates 92 fixedly mounted at both ends of the top of the base plate 91, and rotating rods 96 rotatably mounted on the inner walls of the two support plates 92, with bevel gears 97 fixedly mounted at both ends of the rotating rods 96, each bevel gear 97 meshing with a fixed mechanism 8. When the rotating rods 96 rotate, the two bevel gears 97 rotate synchronously, transferring torque... The force is evenly distributed to the two fixed mechanisms 8, enabling them to move simultaneously and at the same speed, thereby achieving symmetrical clamping of the optical film, ensuring uniform distribution of clamping force, and improving clamping effect; a drive motor 93 is fixedly installed on the side wall of one of the support plates 92, which serves as a power source, and a drive wheel 94 is fixedly installed on its drive end. The drive wheel 94 drives the driven wheel 95 to rotate through frictional contact, and the driven wheel 95 is fixedly connected to the rotating rod 96, thereby causing the rotating rod 96 to rotate, and the inner wall of the driven wheel 95 is fixedly connected to the center section of the outer wall of the rotating rod 96.

[0029] Please see Figures 1-4 This utility model provides a technical solution: a high-speed optical film prototyping machine, including a machine body 1 with a slide groove 12 on the top, the slide groove 12 providing a stable running track for the conveyor belt 3, the conveyor belt 3 slidably installed on its inner wall can smoothly and continuously transport optical films; a control plate 2 is fixedly installed on one side wall of the machine body 1, and a sliding motor 4 is slidably installed on the inner wall of the control plate 2, the sliding motor 4 can drive the slide rod 7 to move in the horizontal direction, so that the components installed on the slide rod 7 can be positioned and adjusted in the horizontal direction; the slide rod 7 is fixedly installed on the top side wall of the sliding motor 4, and a moving motor 5 is slidably installed on the inner wall of the slide rod 7, the moving motor 5 can drive the prototyping head 10 to move in the vertical direction; a connecting guide rail 6 is fixedly installed on the side wall of the moving motor 5, the bottom of the connecting guide rail 6 is fixedly connected to the end of the inner wall of the slide rod 7, and the prototyping head 10 is fixedly installed on the side wall of the moving motor 5.

[0030] Please see Figures 1-4 This utility model provides a technical solution: a high-speed optical film prototyping machine, including a rubber pad fixedly installed at the end of a fixed rod 87 away from the connecting rod 865. When clamping the optical film, the rubber pad directly contacts the film, which can prevent the hard surface of the fixed rod 87 from directly scratching or squeezing the film, thereby effectively reducing scratches, indentations and other damage on the film surface, ensuring the quality and appearance integrity of the film, and the surface of the rubber pad is provided with anti-slip texture; the surface of the conveyor belt 3 is provided with several ventilation holes, which can improve the ventilation conditions during the conveying process. When conveying the optical film, it can promote air circulation and avoid the humid and stuffy environment under the film due to poor air circulation, which helps to keep the film dry and stable, and prevent the film from deforming or sticking due to moisture. Baffles are fixedly installed on both sides of the conveyor belt 3, and the baffles are slidably connected to the inner wall of the chute 12.

[0031] Working principle: First, the optical film to be sampled is placed on the conveyor belt 3 and the equipment is started. At this time, the power transmission of the drive mechanism 9 drives the fixing mechanism 8 to operate and achieve stable clamping and fixing of the optical film: the drive motor 93 starts, driving the drive wheel 94 to rotate. The friction of the drive wheel 94 drives the driven wheel 95 to rotate, which in turn causes the rotating rod 96 to rotate. The bevel gears 97 at both ends of the rotating rod 96 rotate accordingly. The bevel gears 97 mesh with the bevel gear 82, driving the bevel gear 82 to rotate, which causes the threaded column 83 to rotate. The slide plate 81 slides upward under the action of the thread. During the upward sliding of the slide plate 81, the clamping arms 85 and 86 rotate around the rotating shaft 864, causing the fixing rod 87 to move towards the conveyor belt. The optical film on the 3rd is brought close and pressed down to complete the contact and clamping of the film. For films of different widths, the position of the fixing rod 87 can be adjusted by adjusting the screw connecting the fixing rod 87 and the connecting rod 865 to ensure stable clamping. After the film is fixed, the control board 2 controls the sliding motor 4 to slide along the inner wall of the control board 2, driving the sliding rod 7 to move; at the same time, the moving motor 5 slides on the inner wall of the sliding rod 7, driving the sample head 10 to move in the horizontal and vertical directions, using the blade to cut, and achieving precise cutting with infrared positioning, to sample the fixed optical film. After the sample is completed, the drive mechanism 9 operates in reverse, the fixing mechanism 8 releases the clamping of the film, and the conveyor belt 3 sends the sampled film out of the equipment.
