Description

Technical Field

[0001] This utility model relates to the field of conductive film pretreatment technology, specifically to a pretreatment device for a flexible transparent conductive film with high transmittance and high adhesion. Background Technology

[0002] The development of flexible electronic devices and the rise of wearable devices have spurred demand for transparent conductive materials. Research and industry are actively developing novel transparent conductive materials, including conductive polymers, graphene and carbon nanotubes, metal meshes, and metal nanowires. Among these novel transparent conductive materials, metal nanowires, due to their excellent conductivity, light transmittance, and flexibility, are considered a novel transparent conductive material to replace indium tin oxide and are widely used in the fabrication of transparent conductive films.

[0003] For example, CN207097541U discloses an apparatus for processing transparent conductive films. This apparatus includes a conveying device with a substrate on it. Above the substrate, a container for holding a suspension of metal nanowires, a Mayer rod, a microwave processing cavity, and rollers are sequentially arranged. Several droppers are located at the bottom of the container, and the container is connected to the droppers. A heating device is located below or inside the conveying device between the Mayer rod and the microwave processing cavity. The distance between the Mayer rod, microwave processing cavity, and rollers and the substrate is 12–24 μm, and the distance between the droppers and the substrate is 1–5 cm. The apparatus for processing transparent conductive films provided by this invention adopts an assembly line design, placing the container for holding the suspension of metal nanowires, the Mayer rod, the heating device, the microwave processing cavity, and the rollers on a single production line to process the conductive films sequentially, resulting in simple and efficient operation.

[0004] However, existing conductive film pretreatment devices use fixed processing equipment in one place during the pretreatment process. When dealing with conductive films of different thicknesses, it is difficult to adjust the height and position of the pretreatment according to the different thicknesses, which may result in incomplete pretreatment. Therefore, those skilled in the art provide a high-transmittance, high-adhesion flexible transparent conductive film pretreatment device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a pretreatment device for flexible transparent conductive films with high transmittance and high adhesion, which solves the problem that existing conductive film pretreatment devices use fixed processing equipment in one place during the pretreatment process. When dealing with conductive films of different thicknesses, it is difficult to adjust the height and position of the pretreatment according to the different thicknesses, resulting in incomplete pretreatment.

[0006] This utility model provides the following technical solution: a pretreatment device for a high-transmittance, high-adhesion flexible transparent conductive film, comprising a frame for supporting an inner cavity component, a placement frame for placing the conductive film fixedly connected to the lower side of the center of the inner cavity of the frame, two sets of adjustment mechanisms for adjusting the air outlet position fixedly arranged on the lower side of the center of both sides of the frame, a movable mechanism for adjusting the heating position fixedly arranged at the center of the top of the frame, and a controller for controlling the adjustment mechanism and the movable mechanism fixedly connected to the center of one end of the frame.

[0007] As a preferred embodiment of the above technical solution, the adjustment mechanism includes a support rod, which is fixedly connected to the lower side of one end of the frame. A first fixing column is fixedly connected to the end of the support rod away from the frame, and a first motor is fixedly connected to the top of the first fixing column.

[0008] As a preferred embodiment of the above technical solution, a rotating shaft is rotatably connected to the center of both ends of the first motor, a worm gear is fixedly connected to the outer side of the rotating shaft, a first connecting post is rotatably connected to the outer side of one end of the rotating shaft, and the first connecting post is fixedly connected to one end of the frame.

[0009] As a preferred embodiment of the above technical solution, a second connecting column is fixedly connected to the center of one side of the frame, and a lifting shaft is rotatably connected to the inner cavity of the second connecting column. A worm is fixedly connected to the bottom end of the lifting shaft, and the worm and worm wheel are meshed together. A transmission column is fixedly connected to the top end of the lifting shaft. Two sets of transmission columns are symmetrically arranged, and an air knife is fixedly connected between the two sets of symmetrically arranged transmission columns.

[0010] As a preferred embodiment of the above technical solution, the movable mechanism includes a second motor, which is fixedly connected to the center of one side of the top of the frame. A screw is threadedly connected to the center of the inner cavity of the frame, and two sets of symmetrically arranged guide shafts are fixedly connected to the inner cavity of the frame.

[0011] As a preferred embodiment of the above technical solution, the outer sides of the two symmetrically arranged guide shafts are slidably connected with movable columns, and the movable columns are threadedly connected to the outer side of the screw. The bottom end of the movable columns is fixedly connected with a heat regulator, and the bottom end of the heat regulator is fixedly connected with a heating tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention incorporates an adjustment mechanism. A controller activates a first motor, which in turn drives the rotating shafts at both ends to rotate. As the shafts rotate, the worm gear on their outer sides also rotates. Since the worm gear meshes with a worm, its rotation drives the worm to rotate, which in turn drives the lifting shaft to rotate within the inner cavity of the second connecting column. This rotation of the lifting shaft causes it to move up and down. As the lifting shaft moves up and down, the transmission column at the top also moves up and down, thereby raising and lowering the air knife between the two sets of transmission columns. This adjusts the air knife's outlet position, allowing it to blow air onto the conductive film surface at an appropriate height according to the film's position and pretreatment requirements, performing cleaning and other pretreatment operations.

[0014] Based on the aforementioned beneficial effects, this utility model incorporates a movable mechanism. A controller activates a second motor, which in turn rotates the screw within the frame's inner cavity. Because the movable column is threaded onto the outside of the screw and slidably connected to the outside of two symmetrically arranged guide shafts, the movable column moves along the length of the screw under the guidance of the guide shafts when the screw rotates. As the movable column moves, the heat regulator and heating tube at its bottom also move together, adjusting the heating position. Simultaneously, the heat regulator can adjust the heating temperature of the heating tube according to the requirements of the pretreatment process, ensuring that the heating tube heats the conductive film at a suitable position and temperature, thereby improving the film's transmittance and adhesion.

[0020] 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.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution: a pretreatment device for a flexible transparent conductive film with high transmittance and high adhesion, comprising a frame 1 for supporting the inner cavity components, a placement frame 2 for placing the conductive film fixedly connected to the lower side of the center of the inner cavity of the frame 1, two sets of adjustment mechanisms 3 for adjusting the air outlet position fixedly arranged on the lower side of the center of both sides of the frame 1, an movable mechanism 4 for adjusting the heating position fixedly arranged at the center of the top of the frame 1, and a controller 5 for controlling the adjustment mechanism 3 and the movable mechanism 4 fixedly connected to the center of one end of the frame 1.

[0022] The frame 1 supports all internal components, providing a stable working space for the entire pretreatment process; the placement frame 2 securely holds the conductive film, preventing displacement during pretreatment and ensuring accurate processing position; two sets of adjustment mechanisms 3 can flexibly adjust the air outlet position and adjust the height of the air knife 311 according to the specific conditions of the conductive film, ensuring more precise pretreatment operations such as cleaning the film surface; the movable mechanism 4 can adjust the heating position, and together with the heat regulator 45, controls the heating temperature, allowing precise heating of different areas of the film and improving film performance; the controller 5 coordinates the control of the adjustment mechanism 3 and the movable mechanism 4, enabling all parts to work together, improving pretreatment efficiency and quality, and ultimately helping to improve the transmittance and adhesion of the flexible transparent conductive film.

[0023] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the adjustment mechanism 3 includes a support rod 31, which is fixedly connected to the lower side of one end of the frame 1. The end of the support rod 31 away from the frame 1 is fixedly connected to a first fixing post 32, and the top of the first fixing post 32 is fixedly connected to a first motor 33.

[0024] The support rod 31 provides stable support for the entire adjustment mechanism 3, ensuring that it will not easily shake during operation; the first fixed column 32 can firmly fix the first motor 33, preventing the motor from shifting due to vibration during operation; the first motor 33, as the power source of the adjustment mechanism 3, can provide continuous and stable power to the subsequent transmission structure, ensuring the smooth progress of the adjustment process.

[0025] As one implementation method in this embodiment, please refer to Figures 1-2As shown, a rotating shaft 34 is rotatably connected to the center of both ends of the first motor 33. A worm gear 35 is fixedly connected to the outer side of the rotating shaft 34. A first connecting post 36 is rotatably connected to the outer side of one end of the rotating shaft 34, and the first connecting post 36 is fixedly connected to one end of the frame 1.

[0026] When the first motor 33 rotates, it drives the rotating shaft 34 to rotate, which in turn drives the worm gear 35 to rotate, thus realizing the transmission of power. The first connecting column 36 supports and limits the rotating shaft 34, ensuring that the rotating shaft 34 will not deviate from the preset trajectory during rotation, making the rotation of the worm gear 35 more stable, and laying a stable foundation for subsequent meshing transmission with the worm 39.

[0027] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, a second connecting column 37 is fixedly connected to the center of one side of the frame 1. A lifting shaft 38 is rotatably connected to the inner cavity of the second connecting column 37. A worm gear 39 is fixedly connected to the bottom end of the lifting shaft 38. The worm gear 39 and the worm wheel 35 are meshed together. A transmission column 310 is fixedly connected to the top end of the lifting shaft 38. Two sets of transmission columns 310 are symmetrically arranged, and an air knife 311 is fixedly connected between the two sets of symmetrically arranged transmission columns 310.

[0028] The second connecting column 37 provides a rotation support point for the lifting shaft 38, ensuring that the lifting shaft 38 can rotate stably; the worm gear 39 meshes with the worm wheel 35, converting the rotational motion of the worm wheel 35 into the lifting motion of the lifting shaft 38, which in turn drives the air knife 311 to rise and fall through the transmission column 310, realizing the adjustment of the air outlet position of the air knife 311. The height of the air knife 311 can be adjusted according to the specific situation of the conductive film, improving the pretreatment effect; the air knife 311 can blow out airflow to perform pretreatment operations such as cleaning on the surface of the conductive film.

[0029] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the active mechanism 4 includes a second motor 41, which is fixedly connected to the center of one side of the top of the frame 1. A screw 42 is threadedly connected to the center of the inner cavity of the frame 1, and two sets of symmetrically arranged guide shafts 43 are fixedly connected to the inner cavity of the frame 1.

[0030] The second motor 41 provides power to the movable mechanism 4, driving the screw 42 to rotate; the guide shaft 43 guides the movement of the moving column 44, preventing the moving column 44 from deviating during movement; the rotation of the screw 42 can drive the moving column 44 to move along the guide shaft 43, thereby adjusting the heating position.

[0031] As one implementation method in this embodiment, please refer to Figures 1-4As shown, two sets of symmetrically arranged guide shafts 43 are slidably connected to the outer side of a movable column 44, and the movable column 44 is threaded to the outer side of a screw 42. A heat regulator 45 is fixedly connected to the bottom end of the movable column 44, and a heating tube 46 is fixedly connected to the bottom end of the heat regulator 45.

[0032] The movement of the movable column 44 can move the heat regulator 45 and the heating tube 46 together, thereby adjusting the position of the heating tube 46 so that it can accurately heat different areas of the conductive film; the heat regulator 45 can adjust the heating temperature of the heating tube 46 to meet the temperature requirements of different pretreatment processes; the heating tube 46 can heat the conductive film to improve the performance of the film.

[0033] Working Principle: First, the flexible transparent conductive film to be pretreated is placed in the placement frame 2 inside the frame 1. The controller 5 starts the device, which in turn starts the first motor 33. The first motor 33 drives the rotating shafts 34 at both ends to rotate. When the rotating shafts 34 rotate, the worm gear 35 on their outer side rotates accordingly. Since the worm gear 35 is meshed with the worm 39, the rotation of the worm gear 35 drives the worm 39 to rotate. The worm 39 then drives the lifting shaft 38 to rotate in the inner cavity of the second connecting column 37. The rotation of the lifting shaft 38 causes it to move up and down. When the lifting shaft 38 moves up and down, the transmission column 310 at the top also moves up and down, thereby driving the air knife 311 between the two sets of transmission columns 310 to move up and down. This adjusts the air outlet position of the air knife 311, so that the air knife 311 can blow airflow onto the surface of the film at an appropriate height according to the position of the conductive film and the pretreatment requirements, to perform cleaning and other pretreatment operations. Then, the controller 5 starts the second motor 41, which drives the screw 42 inside the frame 1 to rotate. Because the movable column 44 is threaded to the outside of the screw 42 and slidably connected to the outside of two symmetrically arranged guide shafts 43, when the screw 42 rotates, the movable column 44 will move along the length of the screw 42 under the guidance of the guide shafts 43. When the movable column 44 moves, the heat regulator 45 and the heating tube 46 at its bottom will also move together, realizing the adjustment of the heating position. At the same time, the heat regulator 45 can adjust the heating temperature of the heating tube 46 according to the requirements of the pretreatment process, so that the heating tube 46 can heat the conductive film at a suitable position and temperature, improving the transmittance and adhesion of the film. Throughout the process, the controller 5 coordinates the control of the adjustment mechanism 3 and the movable mechanism 4 to ensure that the air outlet position of the air knife 311 and the heating position and temperature of the heating tube 46 are matched to complete the high-quality pretreatment of the flexible transparent conductive film.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
