Description

Technical Field

[0001] This utility model relates to the technical field of coating equipment, and in particular to a scraping device for an impregnation equipment suitable for Roll-to-Roll (R2R) processes. The scraping device of the impregnation equipment can accurately control the coating thickness and has the function of scraping off and recycling the edge adhesive, so as to improve the coating uniformity, reduce material waste and reduce process costs. Background Technology

[0002] With increasing demands for precision manufacturing processes, coating equipment is playing an increasingly important role in the production of various films, electronic substrates, and functional materials. Most existing coating systems employ continuous roller technology, using rollers to evenly apply adhesive to the substrate surface, supplemented by thermosetting to accelerate drying. However, traditional equipment still faces certain technical bottlenecks in terms of coating uniformity, tension control, and droplet supply stability. Furthermore, to meet the demands of large-area, high-speed production, current equipment is often bulky, hindering space allocation and energy management.

[0003] In similar roll-to-roll (R2R) processes, edge thickness is also a common issue when manufacturing prepreg, where excessive adhesive buildup on both sides of the substrate leads to defects such as wrinkles, collapse, lateral slippage, or interlayer slippage during subsequent winding, severely impacting product quality and yield. Current technologies lack effective and systematic solutions to the edge thickness problem, resulting in increased adhesive waste, lower yields, and difficulty in effectively controlling process costs.

[0004] Therefore, the industry urgently needs an innovative device that integrates roller coating, material feeding and receiving, precise droplet flow control, and edge adhesive scraping and diversion. This device can not only improve coating uniformity and finished product yield, but also effectively reduce adhesive waste and overall process costs through edge adhesive recycling. The introduction of this new coating system is expected to simultaneously achieve multiple benefits, including increased production efficiency, energy saving and carbon reduction, and process optimization.

[0032] Please refer to the following: Figures 1 to 6 . Figure 1 This is a schematic diagram showing the configuration of the scraping device in the impregnation equipment of this utility model. Figure 2 This is a three-dimensional schematic diagram of the scraping device of the impregnation equipment of this utility model. Figure 3 , 4These are the front view and top view of the scraping device of the impregnation equipment of this utility model. Figure 5 This is a schematic diagram showing the displacement of the scraping device in the impregnation equipment of this utility model. Figure 6 This is a schematic diagram of the scraper seat of the scraping device of the impregnation equipment of this utility model.

[0033] As shown in the figure, the scraping device 1 of the impregnation equipment of this utility model is disposed on one side of the two metering rollers 91 in the substrate conveying path P of the impregnation equipment 9, and relative to the impregnation tank 92.

[0034] The substrate conveying path P is used to convey the substrate S, which is also referred to as "sheet", "cloth", "material" or "web". This term is used here as a superordinate concept to describe any flexible sheet material. The flexible sheet material includes metals, non-metals, one or more of the above materials, and its construction form includes at least carbon fiber, metal plate (foil), containing one of the above materials, or a composite material with at least two of the above materials, such as glass fiber, carbon fiber, etc.

[0035] The impregnation tank 92 contains the impregnation liquid or adhesive, which is a matrix resin. Other terms may include "adhesive", "slurry", "adhesive liquid", "glue", "varnish", "varnish water", "varnish". The matrix resin includes thermosetting resin or thermoplastic resin, and its composition includes one or more organic polymer compounds, inorganic materials, or combinations of organic and inorganic materials, such as epoxy resin, phenolic resin, polyimide resin, etc.

[0036] The impregnation equipment 9 operates as follows: the substrate S is conveyed to the guide rollers of the impregnation equipment 9 via an unwinding machine or similar mechanism, and then to the impregnation tank 92, where the substrate S is impregnated with the adhesive in the impregnation tank 92. Next, the impregnation rollers of the impregnation equipment 9 guide the substrate S to the metering roller 91 and a scraper mechanism for metering, ensuring the substrate S achieves a predetermined impregnation amount. Subsequently, the scraping device 1 of the impregnation equipment is adjusted to the side of the substrate S to perform quantitative scraping. The scraped adhesive is recycled and reused. The substrate S is then cured in a dryer to produce a prepreg, and finally, it is wound up by a rewinding machine.

[0037] The scraping device 1 of the impregnation equipment of this utility model mainly includes at least one scraping module 2 and a number of recycling and guiding modules 3 equal to the number of scraping modules 2. Preferably, the scraping device 1 of the impregnation equipment of this utility model may include a number of recycling units 4 equal to the number of recycling and guiding modules 3.

[0038] In this embodiment, the scraping module 2 is disposed on at least one side of the substrate S located on the substrate conveying path P. In this embodiment, the scraping module 2 is configured as a pair, respectively disposed on both sides of the substrate S, to scrape off a predetermined width of adhesive material from the side edges of the substrate S. The scraping module 2 includes a scraper 21. The scraper 21 is configured to contact and scrape off the adhesive material from the edge of the substrate S; in this embodiment, there are two scrapers 21, which can simultaneously scrape off the adhesive material from the front and back (or front and back, or top and bottom) of the side edges of the substrate S. Preferably, the scraper 21 is made of a wear-resistant material and forms a line contact with the edge of the substrate S to scrape off the adhesive material.

[0039] Furthermore, the scraper 21 is adjustablely disposed in the scraping module 2 to adjust the edge width of the scraper 21 contacting the substrate S along the width direction of the substrate S. The scraping module 2 has a displacement adjustment mechanism 22; the displacement adjustment mechanism 22 includes an operating element 221, a steering mechanism 222, and a fine-tuning module 223. The operating element 221, in manual mode, is a common or conventional handle; in automatic mode, it can be a combination of an explosion-proof servo motor and a shaft. The operating element 221 is not configured parallel to the width direction of the substrate S. The operating element 221 is connected to the steering mechanism 222. The steering mechanism 222 is connected to the fine-tuning module 223, which in turn is connected to the scraper holder 23 that carries the scraper 21. Preferably, the steering mechanism 222 and the operating element 221 are connected via a coupling.

[0040] The fine-tuning module 223 includes a support assembly 224 and a fine-tuning screw 225. The support assembly 224 is fixed to the scraping module 2. Preferably, the support assembly 224 includes two plates and two guide rods. The two plates are spaced apart along the width direction of the substrate S, and one of the plates is fixed to the scraping module 2. The two guide rods are spaced apart along the direction of the substrate conveying path P. The fine-tuning screw 225 is disposed between the two guide rods, one end of which is connected to the deflector 222, and the scraper seat 23 is screwed onto the fine-tuning screw 225.

[0041] Furthermore, the scraper 21 is adjustablely mounted on the scraper holder 23, and the scraper holder 23 is configured to adjust one or a combination of the contact angle and contact pressure of the scraper 21 relative to the edge of the substrate S. The scraper holder 23 includes a scraper adjustment module 231, which is configured to adjust the position and angle of the scraper 21 relative to the substrate S. The scraper adjustment module 231 may consist of two clamps; one clamp is fixed to a rotating rod, which can be rotated and fixedly positioned on the scraper holder 23, while the other clamp can be clamped and released by locking or other means. Thus, it is possible for an operator to adjust one or a combination of the contact angle and contact pressure of the scraper 21 against the substrate S. The scraper 21 is adjusted and controlled by an operator via the scraper adjustment module 231, ensuring that the blade tip applies appropriate linear pressure to the substrate S (the impregnated fabric) without causing defects on the surface of the substrate S. Preferably, the thickness of the adhesive removed by the scraper 21 is less than the thickness of the fabric. In addition, the contact angle is preferably an acute angle.

[0042] Two recycling and diversion modules 3 are respectively disposed below the scraping module 2. The recycling and diversion modules 3 collect the adhesive material scraped off by the scraper 21. Preferably, the scraper seat 23 may have an opening corresponding to the position of the scraper 21, so that the adhesive material scraped off by the scraper 21 can flow into the recycling and diversion modules 3 through the opening.

[0043] Furthermore, the recycling and diversion module 3 includes a first adhesive collection tank 31 and a second adhesive collection tank 32. One end of the first adhesive collection tank 31 directly receives the adhesive scraped off by the scraper 21. One end of the second adhesive collection tank 32 is connected to the other end of the first adhesive collection tank 31. Preferably, the extension directions of the first adhesive collection tank 31 and the second adhesive collection tank 32 are opposite to each other, and the opening direction of the first adhesive collection tank 31 is opposite to the opening direction of the second adhesive collection tank 32. The first adhesive collection tank 31 is arc-shaped, and the second adhesive collection tank 32 is inclined, to appropriately guide the collected adhesive to flow towards the recycling unit 4.

[0044] Two recycling units 4 are respectively connected to the recycling guide module 3. The recycling units 4 are configured to collect the scraped adhesive. In a preferred embodiment, the opening of the scraper seat 23 or the outlet of the second adhesive collection tank 32 may be provided with a filter unit, which can filter impurities in the collected adhesive, thereby increasing the recycling efficiency.

[0045] In general, in order to deal with excess or unused adhesive at the edge of the substrate S, the present invention configures the scraping device 1 of the impregnation equipment on both sides of the substrate S, and the scraper 21 is configured to contact and scrape off the adhesive on the edge of the substrate S to remove uneven, excess or unused adhesive.

[0046] To facilitate operation and adjustment of the scraping width according to different fabric widths, this invention mounts the scraper 21 on a scraper holder 23, which is equipped with a displacement adjustment mechanism 22 for displacement. This design, with its directional configuration, facilitates operation and allows for setting or adjusting the scraper position to suit the width or scraping width requirements of different substrates S. The fine-tuning screw 225 adjusts the pitch according to actual application, thereby adjusting the feed distance of the scraper holder 23 when the operating member 221 rotates one revolution, achieving precise adjustment.

[0047] In addition, a recycling and diversion module 3 is disposed below the scraping module 2. The recycling and diversion module 3 includes a first adhesive collection tank 31 and a second adhesive collection tank 32 to manage the flow path of the adhesive. The first adhesive collection tank 31 directly receives the adhesive scraped off by the scraper 21, and the adhesive can flow to the second adhesive collection tank 32 under the influence of gravity through its arc-shaped extension configuration. Then, in the second adhesive collection tank 32, the adhesive can flow to the recycling unit 4 under the influence of gravity through its inclined extension configuration.

[0048] The scraping device of this invention, through the adjustable setting of the scraper on the scraping module, can precisely control the different widths, angles, and pressures of the scraping material on the edge of the substrate, adapting to the needs of substrates of different sizes and materials, ensuring stable scraping quality without damaging the substrate. Furthermore, by setting up a recycling and diversion module in conjunction with the recycling unit to guide the concentrated recycling of the adhesive material, the adhesive recycling rate can be effectively improved, raw material consumption reduced, achieving cost savings and improved process purity, thereby enhancing industrial application value.

For example, the above embodiments can be arbitrarily combined and applied without conflict; for example, the device embodiments described above are merely illustrative, and the division of modules is merely a logical functional division, and there may be other division methods in actual implementation; for example, multiple modules or components can be combined or integrated into another system, or some features can be ignored or not executed.

The components shown as modules may or may not be physical modules; that is, they may be located in one place or distributed across multiple network modules.
