Abstract
Description
Technical Field
[0001] This utility model belongs to the field of thin film processing technology, and specifically relates to a processing device for polymer thin films. Background Technology
[0002] The microstructure of polymer thin films (i.e., surface structure sizes ranging from less than one micrometer to tens of micrometers) enables them to achieve emerging optical functions such as anti-reflection, polarization, photonic crystals, light extraction, and light diffusion. As a result, polymer thin films hold promise for enhancing the functionality of various optical devices, including displays, solar cells, and traffic lights, and have important applications in fields such as immunoassay chips, cell culture plates, and nanofluidic devices.
[0003] Currently, nanoimprint lithography is one of the commonly used methods for fabricating micro and nanostructures on polymer films. In particular, roll-to-roll (R2R) hot rolling processes have been used in commercial production for the patterning of continuous micro and nanostructures on large-area polymer film surfaces.
[0004] Roll-to-roll hot rolling is a continuous manufacturing technology that involves feeding a polymer film through a heated die roller, heating the film above its glass transition temperature (Tg) to make it soft and easy to shape, and then feeding the polymer film into an imprinting system. The heated polymer film is imprinted using a die roller engraved with micro- and nano-structures. By contacting the die roller with the polymer film and applying pressure, the polymer film fills the structure on the die roller.
[0005] In the hot pressing process, the surface of the polymer film needs to be heated above its glass transition temperature and then rapidly cooled to create the microstructures on the film surface. Currently, the heating process of the polymer film surface is typically controlled by electrically heating the entire roller, which then conducts heat to the film to control the temperature. However, this method suffers from low heating efficiency and has certain application limitations. Furthermore, traditional nanoimprinting technology also suffers from thermal damage to the microstructures in the fabrication of large-area microstructures. Utility Model Content

[0013] As a further improvement of this utility model, a cooling mechanism is provided between the roll forming mechanism and the winding mechanism for cooling the film after the surface microstructure is made. The cooling mechanism includes at least one air-cooled nozzle.
[0014] As a further improvement of this utility model, the transparent roller includes a transparent glass roller section and fixing members disposed at both ends of the transparent glass roller section for covering both ends of the transparent glass roller section, and the transparent roller is connected to the second drive actuator through a connector connected to the fixing member.
[0015] As a further improvement of this utility model, the roll forming mechanism further includes a lifting component, which is connected to the transparent roller and / or the processing roller. The lifting component is used to drive the corresponding roller to move and change the distance between the transparent roller and the processing roller.
[0016] As a further improvement of this utility model, a correction mechanism is provided between the unwinding mechanism and the roll forming mechanism for correcting and adjusting the position of the film before it is transferred to the roll forming mechanism.
[0017] The correction mechanism includes a frame, a displacement adjustment mechanism connected to the frame, and two correction rollers connected to the displacement adjustment mechanism. The correction mechanism also includes a positioning sensor mounted on the frame for sensing the offset of the film passing around the two correction rollers during the feeding process. The displacement adjustment mechanism is used to adjust the position of the correction rollers according to the offset.
[0018] As a further improvement of this utility model, an antistatic mechanism is also provided between the roll forming mechanism and the winding mechanism to eliminate static electricity on the film; and / or, at least one guide roller is also provided on the film conveying path.
[0019] As a further improvement of this utility model, the unwinding mechanism includes an unwinding roller and an unwinding motor. The unwinding roller is rotatably connected to the unwinding motor and is used to unwind the rolled film to be processed.
[0020] The winding mechanism includes a winding roller and a winding motor. The winding roller is rotatably connected to the winding motor and is used to wind the processed film into a roll. The unwinding motor and the winding motor are linked to adjust the tension of the film.
[0021] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.
[0022] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0036] Example:
[0037] Please see Figures 1-3 In a preferred embodiment of this utility model, the polymer film processing apparatus includes an unwinding mechanism 1, a winding mechanism 7, and a roll forming mechanism 4 disposed between the two.
[0038] The unwinding mechanism 1 is used to unload the unprocessed film 8. The unloaded film 8 is then fed to the roll forming mechanism 4 for surface microstructure roll forming. After the surface microstructure roll forming is completed, the film 8 is wound up by the winding mechanism 7. In a preferred embodiment, the film 8 for surface microstructure fabrication is a polymer film.
[0039] Specifically, the roll forming mechanism 4 includes a processing roller 403, a transparent roller 402, a first drive actuator connected to the processing roller 403, and a second drive actuator connected to the transparent roller 402. The first drive actuator drives the processing roller 403 to rotate, and the second drive actuator drives the transparent roller 402 to rotate. The first and second drive actuators are, for example, a motor or a cylinder. The processing roller 403 is made of metal, which facilitates rapid heat absorption and heating under the action of the laser beam 405 and rapid heat transfer to the film 8 to be processed. Micro-nano structures 404 are provided on the outer peripheral wall of the processing roller 403. More specifically, the processing roller 403 includes a roller body and micro-nano structures 404 circumferentially connected to the roller body. The material of the roller body and the material of the micro-nano structures 404 can be the same or different; for example, they can be different. The micro-nano structure 404 is made of nickel, which has high hardness and good thermal shrinkage, while the roller body is made of aluminum alloy. Of course, other inexpensive metals can also be used. Furthermore, a laser heating module 401 is provided on the side of the transparent roller 402 opposite to the processing roller 403. Generally, the laser heating module 401 includes a laser that emits a laser beam 405 and a laser scanning mechanism that controls the scanning direction of the laser beam 405.
[0040] Among them, the micro-nano structure 404 on the outer peripheral wall of the processing roller 403 is a raised structure, and correspondingly, the microstructure formed on the film 8 by the processing roller 403 is a recessed structure. The size of the micro-nano structure 404 and the microstructure ranges from less than one micrometer to tens of micrometers.
[0041] Transparent roller 402 and processing roller 403 are used to clamp the film 8 to be processed. The axes of the two rollers are preferably parallel to ensure that the clamping force on the film 8 is equal at all axial locations. The laser heating module 401 emits a laser beam 405 to the processing roller 403 for heating. More specifically, the laser beam 405 passes through the transparent roller 402 to heat the processing roller 403 and irradiates the local area of the film 8 clamped by the two rollers, thereby forming a heated roller-pressed area 406 irradiated by the laser beam 405. Figure 2 As shown, the heat from the surface of the processing roller 403 is conducted to the film 8 of the clamping portion of the transparent roller 402 and the processing roller 403; then, by utilizing the rotation of the two rollers and the clamping force applied by the two rollers to the film 8, the film 8 is transported and the micro-nano structure pattern is processed onto one side surface of the film 8.
[0042] In actual operation, by controlling the power of the laser heating module 401, the temperature transmitted to the film 8 by the processing roller 403 is controlled, thereby heating the film 8 clamped on the heating surface to above the glass transition temperature.
[0043] Based on the above-mentioned configuration of the roll forming mechanism 4 and the rotation control of the transparent roller 402 and the processing roller 403, the film 8 to be processed can pass between the two rollers and complete the fabrication of the micro-nano structure 404 on one side surface of the film 8, and finally obtain a polymer film with the surface microstructure fabrication completed.
[0044] Furthermore, an infrared temperature sensor is provided near the heating roller pressing area 406. The infrared temperature sensor is electrically connected to the laser heating module 401. The infrared temperature sensor monitors the temperature near the heating roller pressing area 406 irradiated by the laser beam 405 and feeds it back to the laser heating module 401 so that the laser heating module 401 can control the heating temperature of its heating processing roller 403 to be stable.
[0045] Furthermore, the processing roller 403 rotates synchronously with the transparent roller 402 to better form microstructure patterns on the film 8.
[0046] Furthermore, to prevent the microstructure pattern on the film from being damaged by reflow, a cooling mechanism 5 is preferably provided between the roll forming mechanism 4 and the winding mechanism 7 to cool the film 8 after the surface microstructure has been formed. Exemplarily, in a specific preferred embodiment, the cooling mechanism 5 includes at least one air-cooled nozzle, which provides cooling air to the processed film 8 to achieve rapid cooling of the film 8.
[0047] More specifically, the transparent roller 402 in the preferred embodiment is as follows: Figure 3 As shown, its main structure is preferably made of transparent glass material, including a cylindrical transparent glass roller section 4021. To ensure reliable assembly between the two ends of the transparent glass roller section 4021 and the second drive actuator, it is preferable to provide fixing members 4022 covering the ends of the transparent glass roller section 4021 at each end. The fixing members 4022 covering both ends of the transparent glass roller section 4021 ensure the stability of its rotation. By providing fixing members 4022 at both ends, interference of the fixing members 4022 with the laser beam 405 is avoided when the laser passes through the transparent roller 402 and the film 8 to irradiate the processing roller 403, while also ensuring accurate rotation of the transparent roller 402.
[0048] Furthermore, the transparent roller 402 is connected to the second drive actuator via a connector 4023 connected to the fixing member 4022. More specifically, connectors 4023 are fixedly provided on both fixing members 4022, and the two connectors 4023 are preferably coaxially arranged with the two fixing members 4022, so that the transparent roller 402 can be assembled with the drive device, thereby ensuring the accurate driving of the transparent roller 402. The connector 4023 can also be referred to as a rotating shaft.
[0049] It is understood that, in addition to the glass material mentioned above, the transparent roller 402 in the preferred embodiment can also be made of other transparent materials, as long as they can meet the transmission requirements of the laser beam 405 and the heat resistance requirements of the film 8 after it is heated. This will not be elaborated here.
[0050] More specifically, the roll forming mechanism 4 also includes a lifting assembly connected to the transparent roller 402 and / or the processing roller 403. The lifting assembly controls the displacement adjustment of the corresponding roller shaft, thereby changing the distance between the transparent roller 402 and the processing roller 403. For example, in... Figure 2 In the specific embodiment shown, the transparent roller 402 is positioned above the processing roller 403. Preferably, at least one roller shaft of the transparent roller 402 and the processing roller 403 is connected to a lifting assembly. By controlling the lifting assembly, the distance between the two roller shafts in the roll forming mechanism 4 can be adjusted, thereby adjusting the clamping force applied to the film 8 by the two roller shafts (i.e., the pressure applied to the film 8) and changing the gap between the two roller shafts. Furthermore, by providing the lifting assembly, the processing device can be adapted to films 8 with different thicknesses, materials, and microstructures requiring different processing methods. The lifting assembly can be a conventional component in the prior art, such as a motor or cylinder as the drive actuator, and may also include other necessary connecting components.
[0051] To further ensure the processing accuracy and quality of the film 8, a correction mechanism 3 is preferably provided between the unwinding mechanism 1 and the roll forming mechanism 4. This correction mechanism 3 pre-adjusts the film 8 as it is conveyed to the roll forming mechanism 4, ensuring that the film 8 is in a precise position during surface microstructure fabrication. Exemplarily, in one specific embodiment, the correction mechanism 3 includes a frame, a displacement adjustment mechanism connected to the frame, and two correction rollers spaced apart on the feeding path and connected to the displacement adjustment mechanism. The correction mechanism 3 also includes a positioning sensor mounted on the frame. This sensor senses whether the offset of the film 8 passing around the two correction rollers during the feeding process meets expectations. If the offset exceeds the limit, the displacement adjustment mechanism adjusts the position of the corresponding correction roller, thereby correcting the film material during the feeding process. The displacement adjustment mechanism can be a conventional structure from the prior art, as long as it achieves the desired function.
[0052] More specifically, an antistatic mechanism 6 is provided between the roll forming mechanism 4 and the winding mechanism 7 to eliminate static electricity on the film 8, thereby ensuring reliable winding of the film 8.
[0053] Furthermore, at least one guide roller 2 is also provided on the conveying path of the film 8, specifically, preferably between two adjacent mechanisms, to achieve adjustment of the conveying direction of the film 8 and tensioning of the film 8. For example, in... Figure 1In the preferred embodiment shown, at least one guide roller 2 is provided between the unwinding mechanism 1 and the correction mechanism 3, between the correction mechanism 3 and the roll forming mechanism 4, and between the roll forming mechanism 4 and the winding mechanism 7, to ensure the reliability of film 8 conveying and processing.
[0054] More specifically, the unwinding mechanism 1 includes an unwinding roller and an unwinding motor. The unwinding roller is rotatably connected to the unwinding motor and is used to unwind the rolled film to be processed. The winding mechanism 7 includes a winding roller and a winding motor. The winding roller is rotatably connected to the winding motor and is used to roll up the processed film. The unwinding motor and the winding motor are linked to adjust the tension of the film.
[0055] For the processing apparatus in the preferred embodiment, it preferably includes the following process in actual use:
[0056] (1) Unwinding and feeding: The rolled film 8 to be processed is continuously unwound by the unwinding roller;
[0057] (2) Feeding correction: During the feeding process, the position offset of the film 8 to be processed is monitored in real time when it is fed to the roll forming mechanism 4, and the feeding position is automatically adjusted by the process correction mechanism 3 after the position offset exceeds the limit.
[0058] (3) Laser heating: By adjusting the power of the laser beam 405 emitted by the laser heating module 401, it is ensured that the laser beam 405 irradiating the processing roller 403 can heat the surface of the processing roller 403 to the expected temperature range and keep it stable.
[0059] (4) Perform microstructure hot pressing on the surface of the film: The film 8 to be processed is fed between the transparent roller 402 and the processing roller 403. The micro-nano structure 404 on the surface of the processing roller 403 is tightly attached to one side surface of the film 8. Combined with the heating effect of the laser beam 405, the surface temperature of the film 8 reaches above the glass transition temperature. With the synchronous rotation control of the two roller shafts, the film 8 is continuously transported and the microstructure processing on the surface of the film 8 is completed during the transport process. The micro-nano structure 404 is accurately pressed onto one side surface of the film 8.
[0060] (5) Cooling and shaping: After the film 8 leaves the two rollers in the roll forming mechanism 4, it is cooled by the cold air nozzles in the cooling mechanism 5, which is beneficial to the high-precision forming of microstructure patterns.
[0061] (6) Winding: The film 8 with the surface microstructure made is neatly wound onto the winding roller to complete the surface microstructure making of the polymer film.
[0062] The polymer film processing device of this invention has a simple structure and can accurately and rapidly heat the surface of the microstructure forming roller through the action of laser, thereby ensuring rapid and accurate control of the surface temperature of the film to be processed. This improves the efficiency and quality of microstructure pattern imprinting, ultimately achieving high-throughput processing of polymer films in microstructure pattern imprinting. Compared with the traditional method of heating the film around the heating roller, the local heating of the laser beam has more precise temperature control. Moreover, laser heating is instantaneous, which helps to avoid overheating or thermal damage to the film, and avoids the thermal stress and deformation of the material caused by overall heating of the film. Furthermore, laser heating has high energy utilization and rapid heating. Due to its local selective heating characteristics, it can reduce the cooling time.
[0063] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
