Description

Technical Field

[0001] This utility model relates to the field of safety management of hazardous chemicals, and more specifically to an adjustable shelf device for a safety storage cabinet that enables multiple functions. Background Technology

[0002] Reagent storage safety cabinets are key equipment for laboratory safety management, used to regulate the storage of hazardous chemicals (such as flammable, corrosive, and toxic reagents) and prevent accidents such as leaks, fires, and explosions. With the deep integration of the Internet of Things (IoT), artificial intelligence (AI), and reagent storage safety management, the demand for intelligent reagent storage cabinets is becoming increasingly prominent. RFID technology is widely used in intelligent reagent storage cabinets; RFID intelligent reagent cabinets are equivalent to traditional reagent storage cabinets. They offer automated and precise management capabilities with second-level identification: each reagent bottle is bound to an RFID tag (unique code), and the in-cabinet reader can automatically identify the type and quantity of reagents. They support simultaneous reading of multiple tags, completing a full cabinet inventory within one minute with an error rate of <0.1%, improving efficiency by more than 90% compared to manual inventory. The entire process is automated, automatically generating electronic ledgers that record the entire lifecycle data of reagents from warehousing, issuance, return to disposal, achieving "traceability of source and destination."

[0003] However, most RFID smart reagent cabinets in China simply deploy RFID reading antennas evenly on the back, sides, and top of the cabinet. When the number of reagents with RFID tags is densely packed inside the cabinet, missed reads are very likely to occur. When a missed read occurs, the intelligent system will determine that the reagent corresponding to that RFID tag is no longer in the cabinet, causing system data errors and discrepancies between the system data and the actual information. This method of RFID antenna placement on the cabinet cannot accurately locate the layer of reagents inside, thus lacking the ability to classify and manage reagent storage in the reagent management system. Furthermore, RFID antenna placement on the cabinet can lead to cross-reading of RFID tags outside the cabinet if the cabinet's sealing is poor, causing system data corruption. Utility Model Content

[0004] This utility model proposes a multifunctional adjustable shelf device, the purpose of which is to solve the problems of missed reading and cross-reading caused by the layout of RFID antennas on the cabinet.

[0005] To achieve the above technical solution, the present invention adopts the following technical solution: An adjustable shelf device for multiple functions includes: a housing, the housing being injection molded from PP material, the upper and lower layers of the housing being fixed together at their peripheries, with a hollow mounting space layer in the middle; the upper surface sidewall of the housing protrudes upward, and a main flow channel is formed along the sidewall on the upper surface of the housing; a flow port is provided on one side of the housing, the flow port being connected to the main flow channel; an RFID antenna, which is disposed in the mounting space layer to sense RFID tags on the bottom of bottles placed on the upper surface of the housing, the RFID antenna being communicatively connected to an external system; and a weighing sensor, which is installed in the mounting space layer and connected to the external system.

[0006] Preferably, the bottom of the lower layer of the outer shell is provided with multiple reinforcing ribs.

[0007] Preferably, the upper surface of the outer casing is provided with multiple reagent bottle placement positions, and a weighing sensor is provided for each reagent bottle placement position.

[0008] Preferably, the reagent bottle placement position is recessed downward relative to the upper surface of the outer shell, and a sub-channel is formed in the recess, which converges to the main channel.

[0009] By adopting the above technical solution, the shelf of this utility model can sense the reagent bottles on the upper surface of the shelf through the built-in RFID antenna, realizing the RFID tag reagent shelf-level positioning, ensuring the accuracy of data in the intelligent reagent storage cabinet. The shelf-level positioning can further realize the partitioned storage of intelligent reagent storage cabinet to solve the problem of reagent classification storage and safe management. In addition, the addition of a weighing sensor can effectively weigh the reduced amount of reagent used, providing accurate data on the amount of reagent used by the system's associated personnel, and providing data support for the realization of electronic reagent usage records.

[0011] Figure 3 This is a schematic diagram of the structure of the second embodiment of the present invention. Detailed Implementation

[0012] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0013] See Figure 1 and Figure 2As shown, this is the first embodiment of the present invention, which includes a housing 1, two sets of RFID antennas 2 and two single-point weighing sensors 3.

[0014] The outer shell 1 is injection molded from PP material, integrally formed, structurally stable, and capable of bearing weight. Furthermore, the choice of PP material ensures that the shelves can bear sufficient weight while preventing interference with the RFID antenna reading signal. The outer shell consists of three layers: upper, middle, and lower. The upper and lower layers are fixed together around their perimeters. The middle layer is a hollow installation space. The upper surface sidewall 11 of the outer shell 1 protrudes upwards, and a main drainage channel 12 is formed along the bottom of the sidewall 11 on the upper surface of the outer shell 1. A drainage port 13 is provided on one side of the outer shell 1, and the drainage port 13 is connected to the main drainage channel 12 to prevent leakage. Multiple reinforcing ribs 14 are provided at the bottom of the lower layer of the outer shell 1.

[0015] Two sets of RFID antennas 2 are arranged side-by-side within the mounting space layer to sense the RFID tags on the bottom of the two rows of bottles placed on the upper surface of the outer casing. The RFID antennas 2 are communicatively connected to an external system, and their interfaces 21 are located on one side of the outer casing 1. The RFID antennas 2 directly read the bottle bottom information on this layer, preventing missed readings when the number of reagents with RFID tags is densely packed in the reagent storage cabinet, thus improving overall accuracy. A single-point weighing sensor 3 is installed within the mounting space layer and connected to the external system. The weighing sensor effectively measures the reduced amount of reagent used, providing accurate data on reagent usage for system-related personnel and ensuring data security for the electronic recording of reagent usage.

[0016] See Figure 3 The image shows a second embodiment of this utility model. This embodiment optimizes the configuration of the weighing sensor compared to the first embodiment. Multiple reagent bottle placement positions 4 are provided on the upper surface of the outer casing, and a weighing sensor 3 is provided corresponding to each reagent bottle placement position 4. The reagent bottle placement position 4 is recessed downwards relative to the upper surface of the outer casing 1, and a branch flow channel 5 is formed in the recess, which converges to the main flow channel. This further ensures accurate measurement of the data for each reagent.

[0017] The dimensions of the shelf in this utility model are approximately 980*370*60mm.

[0018] This invention utilizes RFID antennas embedded within shelves to sense bottles with RFID tags on their bottoms. This avoids the issues of missed readings, incorrect readings, and cross-reading that occur when multiple bottles overlap in existing technologies, increasing the accuracy of RFID tag positioning and reading. Simultaneously, the shelves facilitate adjustments to the cabinet's storage space and reagent weighing, enabling zoned storage and weighing management within the intelligent cabinet. This provides effective control, eliminating concerns about missed or incorrect readings of reagent tag signals. The use of this product effectively solves the problems of missed and cross-reading of RFID reagent tags within the cabinet, while simultaneously achieving shelf-level positioning of RFID tags and reagent weighing, significantly improving the management accuracy of intelligent reagent management cabinets.

[0019] The embodiments described above are for illustrative purposes only and are not intended to limit the scope of this utility model. All equivalent changes and modifications made to this utility model by those skilled in the art should fall within the scope of the appended claims.
