Description

Technical Field

[0001] This utility model relates to the field of light guide film coating and imprinting technology, and in particular to an online coating and imprinting composite equipment for light guide films. Background Technology

[0002] In the production of electronic components such as display panels and backlight modules, online coating, imprinting, and lamination equipment for light guide films is the core equipment for achieving large-scale production of light guide films. Its core function is to form a specific optical structure on the surface of the base film through processes such as coating, imprinting, and lamination, ensuring the uniform light guiding performance of the light guide film. Existing equipment has significant technical limitations in the replacement and handling of the light film tube, which restricts production efficiency and operational safety.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following drawbacks often exist: In the replacement of the light guide film tube, traditional equipment typically connects the light guide film tube to the support frame via bolts, clips, or other fixing structures. Replacement requires the use of specialized tools such as wrenches and screwdrivers for gradual disassembly, making the operation cumbersome (each replacement takes approximately 15-20 minutes). Since the production of light guide film is a continuous process, the coating machine must be stopped during the replacement of the light guide film tube, leading to production interruptions and severely impacting capacity. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing technologies require workers to spend a lot of time using specific tools to disassemble and replace the light-guide film tube, causing the coating machine to have to stop working and spend a lot of time waiting for the light-guide film tube to be replaced, thus reducing the working efficiency of the coating machine. To address this, we propose an online coating and imprinting composite equipment for light-guide film.

[0005] To achieve the above objectives, this application adopts the following technical solution: an online coating and imprinting composite equipment for light guide film, including a coating machine, a support frame installed on the upper surface of the coating machine, a light film tube movably connected to the surface of the support frame, and disassembly devices provided on both sides of the support frame. The disassembly devices include four round rods, which are arranged in pairs. The two pairs of round rods are fixedly connected to the two sides of the support frame, and U-shaped plates are slidably connected to the arc surfaces of the two pairs of round rods. A square rod is fixedly connected to one side of the U-shaped plate, and square grooves are provided at both ends of the light film tube.

[0006] Preferably, a baffle plate is fixedly connected to one end of each set of round rods, and the size of the square rod is adapted to the size of the square groove.

[0007] Preferably, a first spring is fitted onto the arc surface of the round rod, and the two ends of the first spring are fixedly connected to the U-shaped plate and the support frame, respectively.

[0008] Preferably, a rubber ring is slidably connected to the arc surface of the round rod, and one side of the rubber ring is fixedly connected to the U-shaped plate.

[0009] Preferably, a screw is fixedly connected to one side of the blocking plate, a snap-fit ​​plate is threadedly connected to the arc surface of the screw, and a snap-fit ​​bracket is fixedly connected to the surface of the U-shaped plate.

[0010] Preferably, the coating machine has sliding grooves on both sides, and the surfaces of the two coating machine sliding grooves are provided with translation devices. The translation devices include two sliding frames, which are slidably connected to the surfaces of the two coating machine sliding grooves respectively. A sliding rod is fixedly connected to one side of the sliding frame, and a support plate is slidably connected to the arc surface of the sliding rod. A placement block is fixedly connected to one side of the support plate.

[0011] Preferably, a circular plate is fixedly connected to one end of the slide rod, and a second spring is sleeved on the arc surface of the slide rod. The two ends of the second spring are fixedly connected to the circular plate and the support plate, respectively.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, by setting a disassembly device, the optical film tube and the support frame can be quickly disassembled and easily replaced. This avoids the situation where, after the optical film on the optical film tube is used up, the operator needs to spend a lot of time using specific tools to disassemble and replace the optical film tube, which would cause the coating machine to stop working and spend a lot of time waiting for the optical film tube to be replaced, thus reducing the working efficiency of the coating machine and improving the practicality of the device.

[0014] 2. In this utility model, by setting up the translation device, the effect of quickly translating the new optical film tube to the top of the support frame is achieved. This avoids the situation where the new optical film tube is thick and heavy, making it difficult for the operator to lift and translate it to the top of the support frame, which could cause the optical film tube to hit the surface of the coating machine and thus damage the optical film tube or other parts of the coating machine. This improves the convenience of using the device. Attached Figure Description

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Reference Figure 1 As shown, this utility model provides a technical solution: an online coating and imprinting composite equipment for light guide film, including a coating machine 1. A support frame 2 is installed on the upper surface of the coating machine 1, and a light film tube 3 is movably connected to the surface of the support frame 2. Disassembly devices 4 are provided on both sides of the support frame 2. By setting the disassembly devices 4, the light film tube 3 can be quickly disassembled from the support frame 2 for easy replacement. This avoids the situation where, after the light film on the light film tube 3 is used up, the operator needs to spend a lot of time using specific tools to disassemble and replace the light film tube 3, causing the coating machine 1 to have to stop working and spend a lot of time waiting for the light film tube 3 to be replaced, thus reducing costs. The improved working efficiency of the coating machine 1 enhances the practicality of the device. Sliding grooves are provided on both sides of the coating machine 1, and translation devices 5 are installed on the surfaces of the two sliding grooves. These translation devices 5 allow for the rapid translation of the new optical film tube 3 directly above the support frame 2. This avoids the situation where, during installation, the new optical film tube 3, being thick and heavy, is difficult for the operator to lift and move to the top of the support frame 2, potentially causing it to impact the surface of the coating machine 1 and resulting in damage to the optical film tube 3 or other components of the coating machine 1. This significantly improves the ease of use of the device.

[0024] The following section will explain the specific setup and function of the disassembly device 4 and the translation device 5.

[0025] Reference Figure 2 and Figure 3 As shown in this embodiment: the disassembly device 4 includes four round rods 401, which are arranged in pairs. The two pairs of round rods 401 are fixedly connected to both sides of the support frame 2. U-shaped plates 402 are slidably connected to the arc surfaces of both pairs of round rods 401. A square rod 403 is fixedly connected to one side of the U-shaped plate 402. Square grooves 404 are provided at both ends of the optical film tube 3. A blocking plate 405 is fixedly connected to one end of each pair of round rods 401. The size of the square rod 403 matches the size of the square groove 404. The blocking plate 405 effectively limits the maximum sliding distance of the U-shaped plate 402 on the arc surface of the round rod 401, preventing the U-shaped plate 402 from being forced to detach due to excessive force applied when the operator pulls it. A first spring 406 is fitted onto the arc surface of the round rod 401. The two ends of the first spring 406 are fixedly connected to the U-shaped plate 402 and the support frame 2, respectively. A spring 406 improves the stability of the square rod 403 when it limits the optical film tube 3. A rubber ring 407 is slidably connected to the arc surface of the round rod 401. One side of the rubber ring 407 is fixedly connected to the U-shaped plate 402. The elasticity of the rubber ring 407 wraps around the arc surface of the round rod 401, thereby slowing down the sliding speed of the U-shaped plate 402 on the arc surface of the round rod 401 and reducing the impact of external shaking on the U-shaped plate 402, thus achieving a damping effect. A screw 408 is fixedly connected to one side of the blocking plate 405. A snap-fit ​​plate 409 is threadedly connected to the arc surface of the screw 408. A snap-fit ​​bracket 410 is fixedly connected to the surface of the U-shaped plate 402, which achieves the effect of limiting the square rod 403 when it is pulled out of the square groove 404. This avoids the situation where the square rod 403 is continuously kept in the position near the square groove 404 when the staff replaces the optical film tube 3, making it inconvenient for the staff to replace the optical film tube 3.

[0026] Reference Figure 4 and Figure 5 As shown, specifically, the translation device 5 includes two sliding frames 51, which are slidably connected to the surfaces of the sliding grooves of the two coating machines 1 respectively. A sliding rod 52 is fixedly connected to one side of the sliding frame 51, and a support plate 53 is slidably connected to the arc surface of the sliding rod 52. A placement block 54 is fixedly connected to one side of the support plate 53, and a circular plate 55 is fixedly connected to one end of the sliding rod 52. A second spring 56 is sleeved on the arc surface of the sliding rod 52. The two ends of the second spring 56 are fixedly connected to the circular plate 55 and the support plate 53 respectively. The second spring 56 achieves the effect of automatically resetting the support plate 53 and the placement block 54, so as to reduce the number of operation steps of the operator and improve the work efficiency of the operator.

[0027] Working principle: When the optical film tube 3 needs to be replaced, the operator pulls the U-shaped plate 402, causing it to slide along the round rod 401 (fixed to the support frame 2) against the elastic force of the first spring 406, thus driving the square rod 403 to be pulled out from the square grooves 404 at both ends of the optical film tube 3. The rubber ring 407 on the round rod 401 (fixed to the U-shaped plate 402) wraps around the round rod 401 with elastic force, slowing down the sliding speed of the U-shaped plate 402 on the arc surface of the round rod 401, reducing the impact of external shaking on the U-shaped plate 402, and playing a damping role. One end of the round rod 401 The baffle plate 405 prevents the U-shaped plate 402 from being pulled off. Then, the snap-fit ​​plate 409 on the screw 408 on one side of the baffle plate 405 is rotated to snap the snap-fit ​​bracket 410 on the surface of the U-shaped plate 402, thereby limiting and fixing the square rod 403 and preventing it from resetting and affecting the replacement of the optical film tube 3. After the replacement is completed, the snap-fit ​​plate 409 is rotated in the opposite direction to release the limit. The first spring 406 pushes the U-shaped plate 402 to reset, so that the square rod 403 is reinserted into the square groove 404 of the optical film tube 3, thus completing the fixing of the optical film tube 3 and ensuring that it is stable and does not shift during operation.

[0028] The sliding frame 51 slides along the sliding groove of the coating machine 1, which can drive the sliding rod 52 and the support plate 53 to move as a whole, and adjust the lateral position of the placement block 54 to adapt to different working conditions. When it is necessary to adjust the longitudinal position of the placement block 54, the support plate 53 is pushed to slide along the sliding rod 52 and compress the second spring 56. After adjustment, the support plate 53 is released, and the second spring 56 (the two ends of which are connected to the circular plate 55 at one end of the sliding rod 52 and the support plate 53 respectively) automatically resets, driving the support plate 53 and the placement block 54 back to the initial position. This reduces the number of operation steps for the operator and improves work efficiency. This structure can flexibly adjust the position of the placement block 54, providing auxiliary support for the disassembly and coating work of the optical film tube 3, and ensuring smooth overall operation.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
