Description

Technical Field

[0001] This utility model relates to the technical field of immunochromatographic assay reagent production equipment, and in particular to an immunochromatographic glass fiber pad drying tray supported by a chrome-plated stainless steel mesh. Background Technology

[0002] Immunochromatographic glass fiber pads are a key component in immunochromatographic assay reagents, primarily used for sample pretreatment, antibody / antigen immobilization, or as reaction carriers. Their performance directly affects the sensitivity and stability of the assay reagents. These glass fiber pads are typically made from glass fibers through processes such as carding, shaping, and cutting. They have a porous structure and require rigorous drying during production to remove moisture, ensuring the quality of subsequent reagent coating and assembly processes.

[0003] In the production of immunochromatographic assay reagents, the drying of glass fiber mats is a core process, and the drying mesh tray is the key equipment for achieving this process. Its performance directly determines the drying efficiency and the final quality of the glass fiber mats.

[0004] Existing drying trays suffer from problems such as uneven air permeability, easy adhesion of fiberglass mats, and inconvenience in handling, which affect the drying quality of fiberglass mats and production efficiency.

[0005] To address this, we propose an immunochromatographic glass fiber pad drying tray supported by a chrome-plated stainless steel mesh. Utility Model Content

[0006] The purpose of this invention is to provide an immunochromatographic glass fiber pad drying tray supported by a chrome-plated stainless steel mesh, thereby solving or at least alleviating one or more of the above-mentioned problems and other problems existing in the prior art.

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0018] This utility model has at least the following beneficial effects:

[0019] The smooth surface of the chrome-plated support mesh reduces friction between the fiberglass pad and the mesh tray, minimizing adhesion and damage during handling.

[0020] The chromium layer acts as a chemical inert barrier, preventing corrosion from acid and alkali components in the reagent, maintaining the openness of the mesh, and ensuring uniform penetration of the drying airflow.

[0026] 1. Metal frame; 2. Stainless steel wire mesh; 3. Reinforcing bar. Detailed Implementation

[0027] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] Please refer to Figures 1 to 2 As shown, an embodiment of this utility model provides an immunochromatographic glass fiber pad drying tray supported by a chrome-plated stainless steel mesh, including a metal frame 1 and a chrome-plated support mesh 2. The chrome-plated support mesh 2 is fixed to the inner side of the metal frame 1 and is used to support the glass fiber pad.

[0029] The metal frame 1 provides rigid support for the entire drying tray, ensuring the overall stability of the structure; the chrome-plated support mesh 2 is fixed inside the metal frame 1 and serves as a component that directly supports the glass fiber mat. Its mesh structure facilitates the penetration of the drying airflow, while the chrome plating layer reduces adhesion to the glass fiber mat, achieving stable placement and efficient drying of the glass fiber mat.

[0030] In this embodiment, the chrome-plated support mesh 2 includes a stainless steel wire mesh, the surface of which is electroplated with a chrome layer.

[0031] The stainless steel wire mesh of the chrome-plated support mesh 2 serves as the basic load-bearing structure, providing sufficient strength to support the glass fiber pad; the chrome-plated layer on the surface forms a dense protective film, which on the one hand enhances corrosion resistance and prevents corrosion by acid and alkali reagents, and on the other hand reduces surface roughness, reduces friction with the glass fiber pad, and avoids adhesion.

[0032] In this embodiment, the chromium layer thickness is 5-8 μm. A chromium layer thickness of 5-8 μm can form a continuous and dense oxide film, which can effectively block the corrosion of the stainless steel wire mesh by external acid and alkali substances, and will not clog the mesh holes due to excessive thickness, ensuring the normal penetration of dry airflow, and balancing corrosion resistance and air permeability. According to the test, this chromium-plated support mesh 2 has a salt spray corrosion resistance time of >1000 hours.

[0033] In this embodiment, the hardness of the chromium layer is ≥900HV.

[0034] Through the above settings, the chrome-plated support mesh 2 can resist friction and corrosion during the handling of the glass fiber pad, maintaining surface smoothness and structural integrity.

[0035] In this embodiment, the surface roughness Ra of the chrome-plated support mesh 2 is ≤0.8μm. This setting reduces the contact friction with the glass fiber pad, preventing the glass fiber pad from being torn or damaged due to adhesion during handling, and also reducing the risk of fiber residue contaminating the mesh tray.

[0036] In this embodiment, the stainless steel wire mesh is an 8-mesh stainless steel wire mesh with a wire diameter of 0.25–0.35 mm.

[0037] The 8-mesh mesh size, combined with a wire diameter of 0.25–0.35 mm, ensures that the stainless steel wire mesh has sufficient structural strength to support the glass fiber mat, while also forming uniform mesh channels. This allows the drying airflow to penetrate the chrome-plated support mesh 2 evenly and act on all areas of the glass fiber mat, improving drying uniformity.

[0038] In this embodiment, the metal frame 1 is a 304 stainless steel frame.

[0039] 304 stainless steel has excellent rigidity and corrosion resistance. As a metal frame 1, it can provide stable rigid support, prevent the frame from deforming under frequent use or high temperature and dry environment, and resist corrosion from possible residual acid and alkali reagents, extend the service life of the frame, and ensure the overall structural stability. During the manufacturing process, it is formed by laser cutting to ensure that the edges of the metal frame 1 are flat and burr-free.

[0040] In this embodiment, a reinforcing rod 3 is fixedly connected to the inner side of the metal frame 1, and the reinforcing rod 3 is located below the chrome-plated support mesh 2.

[0041] The above-mentioned settings can further strengthen the metal frame 1 and improve its anti-deformation performance.

[0042] In this embodiment, the distance between the top of the reinforcing rod 3 and the bottom of the chrome-plated support mesh 2 is 10mm to 15mm.

[0043] The above settings ensure that the gap provides space for the drying airflow, without obstructing the airflow from penetrating the chrome-plated support mesh 2 from below, thus ensuring drying efficiency and uniformity.

[0044] In this embodiment, the metal frame 1 is a rectangular frame, and all four corners of the metal frame 1 are rounded.

[0045] The metal frame 1 is designed as a rectangular frame, which is compatible with common drying racks for immunochromatographic glass fiber pads. The rounded corners at the four corners can prevent sharp edges from scratching operators, and at the same time prevent the glass fiber pad edges from colliding with sharp corners during handling, thus improving operational safety and convenience.

[0046] In this embodiment, the metal frame 1 and the chrome-plated support mesh 2 are fixed by argon arc spot welding. The weld points are polished to remove any protrusions to avoid scratching the fiberglass pad. The chrome plating layer is partially re-plated after welding to ensure consistent overall corrosion resistance.

[0047] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
