Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of AEM film preparation, in particular to an AEM wet film blocking device. Background Art
[0002] As a third-generation electrolytic hydrogen production technology, AEM technology plays a significant role in the membrane industry. AEM membranes are the core component of AEM electrolyzers, and process optimization for AEM membrane preparation is imperative.
[0003] Currently, in the process of preparing AEM membranes, one of the process steps is to use a scraper to evenly scrape the membrane liquid onto the substrate, and then slowly send it into an oven to dry it into a dry film.
[0004] However, in actual use, it was found that during the AEM film preparation process, the AEM film liquid is relatively thin. After the scraper scrapes the film liquid into a wet film, the film liquid still has fluidity. Before drying, the film liquid will diffuse toward the outside of the substrate, or even flow out of the substrate. This not only wastes the film liquid material, but also affects the quality of the formed dry film and the dry film preparation. At the same time, when the film liquid flows to the bottom of the substrate, the membrane liquid will cause the substrate and the equipment to stick together, which may also cause equipment malfunction.
[0005] In order to solve the above problems, an AEM wet film blocking device is proposed. Utility Model Content

[0011] The glue coating mechanism is arranged at an outer position between the bottom plate of the membrane liquid tank and the membrane liquid baffle, and is used to apply glass glue on the side position of the substrate.
[0012] Preferably, the glue coating mechanism includes a glass glue barrel and a glue head, the glue head and the glass glue barrel are connected via a hose, and the glue outlet end of the glue head is facing the position between the membrane liquid baffle and the substrate.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] The utility model provides Figure 1-5 The AEM wet film blocking device shown includes an oven 100, a substrate 200, a membrane liquid baffle 106 and a gluing mechanism. The substrate 200 moves horizontally along the top of the membrane liquid tank bottom plate 101 into the oven 100. The feed port of the oven 100 is equipped with a transmission device for the substrate 200 (such as a roller transmission), so that the substrate 200 can be transported horizontally along the top of the membrane liquid tank bottom plate 101 into the oven 100 for drying. The membrane liquid tank bottom plate 101 is fixedly provided at the feed port of the oven 100. The membrane liquid baffles 106 are symmetrically arranged on both sides of the top of the membrane liquid tank bottom plate 101. A scraping mechanism is provided between the two membrane liquid baffles 106. The scraping mechanism is used to evenly scrape the membrane liquid on the surface of the substrate 200. The distance between the membrane liquid baffles 106 on both sides of the scraping mechanism is the film width of the scraping film. The gluing mechanism is provided between the membrane liquid tank bottom plate 101 and the membrane liquid At the outer position between the baffles 106, the glue coating mechanism is used to apply glass glue to the side position of the substrate 200. During the process of the substrate 200 being transferred from the top of the bottom plate 101 of the membrane liquid tank to the oven 100, since the membrane liquid baffle 106 and the scraper mechanism are both located at the top position of the substrate 200, the membrane liquid on the surface of the substrate 200 can be scraped evenly during the movement of the substrate 200, so that the surface of the substrate 200 is evenly coated with the membrane liquid. The membrane liquid baffle 106 can block the membrane liquid on the surface of the substrate 200, and prevent the scraped membrane liquid from spreading to the two side edges of the substrate 200 due to its fluidity. At the same time, the glue coating mechanism can spray glass glue on the surface of the substrate 200 outside the membrane liquid baffle 106. The thickness of the glass glue should be slightly higher than the thickness of the wet film, so that the glass glue can be used to block the membrane liquid and prevent the membrane liquid from spreading outward along the side of the substrate 200.
[0026] It should be noted that the glue coating mechanism includes a glass glue barrel 300 and a glue head 104, and the glue head 104 is connected to the glass glue barrel 300 through a hose. The glue outlet end of the glue head 104 is facing the position between the membrane liquid baffle 106 and the substrate 200. The glass glue is sent to the glue head 104 through the hose by the pressure inside the glass glue barrel 300, so that the glass glue can be sprayed from the glue head 104 to the substrate 200. By adjusting the pressure inside the glass glue barrel 300, the glass glue is quantitatively pushed into the glue head 104 by pressure, so that the glass glue is evenly coated on both sides of the substrate 200; an auxiliary support structure is installed on the side wall of the oven 100, and the auxiliary support structure is used to support and fix the position of the glue head 104; in a preferred embodiment, as shown in FIG. Figure 5 As shown, the auxiliary support structure includes a glue head fixing frame 103, which is fixedly installed on the two side walls of the feed port of the oven 100, and a glue head 104 is fixedly installed on the end of the glue head fixing frame 103. Through the setting of the glue head fixing frame 103, the glue head 104 can be stably installed above the substrate 200 outside the membrane liquid baffle 106, so that the glue head 104 can accurately spray glass glue on the side of the substrate 200.
[0027] In addition, the scraping mechanism includes a scraper 105, which is rotatably installed between the two membrane liquid baffles 106 and near the end of the feed port of the oven 100. The scraper 105 scrapes the membrane liquid on the surface of the substrate 200 evenly by rotating. The rotation of the scraper 105 is driven by a rotary drive assembly installed outside the oven 100. By utilizing the rotation of the scraper 105 and the translational transmission of the substrate 200, the membrane liquid on the substrate 200 can be scraped evenly, so that the membrane liquid is applied more evenly on the substrate 200.
[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
