[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] like Figures 1 to 6 As shown, the battery diaphragm moisture control storage cabinet of the utility model embodiment includes a storage cabinet body, a walking device 1 is arranged at the bottom of the storage cabinet body, the storage cabinet body includes a cabinet body 2 and a sealing door 5 arranged on one side of the cabinet body 2, and a material rod 7 arranged inside the cabinet body 2, and the cabinet body 2 has an air outlet at the bottom; an air supply unit 4 is installed at the air inlet at the top of the cabinet body 2, which is used to send external air into the cabinet body 2 from the air inlet at the top of the cabinet body, and then flow out from the air outlet at the bottom of the cabinet body.

[0027] The battery diaphragm moisture control storage cabinet of the utility model embodiment provides an air source through the air supply unit 4, continuously delivers the workshop dry air into the cabinet 2, and the air flows through the material placed on the material rod 7 and leaves from the air outlet at the bottom of the cabinet 2, and the moisture in the material is taken away by the air flow; in this application, since the air inlet of the cabinet is at the top and the air outlet is at the bottom, an exhaust cavity is formed above and below, and the air delivered by the air supply unit flows in the exhaust cavity, which can effectively take away the moisture on the surface of the diaphragm, so that by controlling the standing time, it is possible to control the moisture of the material to be kept within the qualified range, thereby improving the product quality.

[0028] There are multiple material rods in the present application, and multiple layers of material rods 7 are arranged at equal intervals from the top to the bottom of the cabinet. Each layer of material rods includes multiple material rods that are spaced from each other and arranged at equal intervals front to back. The diaphragm material is stored on the material rod. Since the diaphragm is a rolled material, the roll core is a hollow material rod, and the core can be used to place the support shaft / material rod, so that the material rod in the present application can be used to store the diaphragm material. The surface of the material is smooth, and stainless steel is used as the material. When the roll core is used to store the diaphragm, friction can be avoided to avoid dust.

[0029] In a preferred embodiment, the air supply unit 4 includes a fan 9 and a motor 8 for driving the fan to rotate, and the motor is installed on a motor bracket 11. The motor bracket is a rectangular frame structure with an opening at the bottom, and is installed on the top of the cabinet. An air inlet channel or air inlet is formed between the motor bracket and the top of the cabinet. The axis of the fan is installed perpendicular to the top surface of the cabinet, so as to facilitate the introduction of external air from the top of the cabinet into the interior of the cabinet, so as to dry the diaphragm material hung on the material rod by blowing air to remove excess moisture in the diaphragm.

[0030] Furthermore, in a preferred embodiment, a filter 3 is arranged at the bottom or lower part of the top of the cabinet 2 at the position of the air inlet, and the air supply unit 4 is installed above the filter 3. A sealing strip or a sealing structure is arranged between the filter and the air inlet to prevent air leakage. By arranging the filter below the air supply unit, dust and other impurities in the air that may affect the quality of the diaphragm can be filtered out, thereby ensuring that the quality of the diaphragm will not be affected by blow drying.

[0031] As mentioned above, the filter is provided to filter the air. For this purpose, an air filter element or air filter material is provided inside the filter. For example, at least one layer of non-woven fabric for filtering is arranged inside the filter. Of course, other available air filter materials or filter mesh plates may also be used, without limitation.

[0032] As mentioned above, in the present application, in order to achieve blowing and drying of the diaphragm through relatively dry air from the outside, an outlet is provided at the bottom of the cabinet. A preferred embodiment is to form a hollow mesh structure 12 on the bottom plate 13 installed at the bottom of the cabinet, and to form the air outlet using the hollow mesh structure 12. Of course, it may also be an air outlet of other structural forms, and is not limited to this.

[0033] In one embodiment, in the present application, preferably, the cabinet body is a rectangular structure, and the sealed door 5 is a double-door structure. Each door is hinged to the cabinet body for easy opening and closing. The hinge can be achieved by hinges, etc., or it can be a single-door structure. There is no specific limitation. In addition, a sealing strip is installed between the cabinet body and the sealed door to prevent air leakage after the sealed door is closed. By increasing the sealing, external dust can be prevented from entering the interior of the cabinet and polluting the diaphragm.

[0034] In one embodiment, a PE protective cover is installed at the outer end of the material rod 7, and numbers are engraved on the surface of the protective cover to digitally mark each material rod, so as to facilitate recording the storage time of each material rod and the diaphragm thereon by numbers, such as marking in sequence from top to bottom with Arabic numerals.

[0035] In order to facilitate observation of the conditions of the materials inside from the outside, in one embodiment, a transparent plate 14 is installed in the hollow area on the surface of the sealed door to facilitate observation of the use of the materials, wherein a handle 6 is installed on the edge of the sealed door to facilitate operation of the sealed door to open or close it, so as to facilitate opening and placing of materials.

[0036] In one embodiment, the walking device 1 includes two universal wheels and two fixed wheels, which facilitate the movement of the storage cabinet to realize moving to the designated area to load and unload materials, such as disassembling the diaphragm packaging in the designated area, and transferring it to the use area after passing through the air shower room, so as to prevent the unpacking process from polluting the workshop environment. Preferably, the universal wheel has a built-in brake structure, and the two fixed wheels are installed on one side and the two universal wheels are installed on the other side.

[0037] From the above description, it can be seen that the storage cabinet which is convenient to implement of the utility model continuously circulates air through the air supply unit on the top of the cabinet, and air flows through the air outlet at the bottom of the cabinet to take away the moisture of the diaphragm material, thereby absorbing the moisture of the diaphragm material inside the storage cabinet, reducing the moisture of the diaphragm material, so as to achieve the moisture level of the diaphragm material meeting the requirements.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.

[0039] Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present invention is limited by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0040] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
