Description

Technical Field

[0001] This utility model relates to the field of hazardous chemical reagent storage technology, and in particular to an intelligent hazardous chemical reagent cabinet. Background Technology

[0002] Hazardous chemical reagent cabinets are devices used to store and manage explosive, flammable, and corrosive chemical reagents. For safety reasons, hazardous chemical management is very cumbersome, requiring two people and two locks for management. Monthly storage and usage logs must be submitted to upper management, and the storage logs and cabinet contents must be verified monthly. Reagents must be neatly arranged by area weekly. Currently, chemical reagent cabinets generally rely on manual operation, which is inefficient and poses safety hazards. They lack data storage and uploading capabilities, requiring researchers to retrieve and record reagents on-site, wasting research time and leading to untimely or incomplete records. With the development of IoT technology and various sensing technologies, intelligent laboratories are becoming a major trend.

[0003] Chinese patent CN213820538U discloses an intelligent hazardous reagent management cabinet based on facial recognition and fingerprint scanning. The cabinet includes a cabinet body, with a motor fixedly connected to the inner wall. A first rotating shaft is fixedly connected to the motor's output end, and a first pulley, a second pulley, and a fixed rod are fixedly connected to the first rotating shaft. A stepped placement platform is fixedly connected to the outer wall of the fixed rod. A second and third rotating shafts are rotatably connected to the inner wall of the cabinet. A third pulley and a first fan blade are fixedly connected to the second rotating shaft, and a fourth pulley and a second fan blade are fixedly connected to the third rotating shaft. The first, second, third, and fourth pulleys are all connected by belts. The cabinet body has a door. This solution has a simple structure, facilitating the user's access to and storage of reagents, greatly saving user time and increasing work efficiency. While this type of technical solution facilitates reagent access, the stability and safety of reagent access cannot be guaranteed, and it cannot automatically record core information such as the person accessing the reagent, the access time, and the amount used.

[0004] Therefore, there is an urgent need for an intelligent hazardous chemical reagent cabinet that can effectively ensure the stability and safety of reagent storage and retrieval, and can also automatically record core information such as the person storing and retrieving the reagent, the storage and retrieval time, and the amount used.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide an intelligent hazardous chemical reagent cabinet. By setting up reagent cabinet partitions, slide rail gripping components, and leakage detection units, the stability and safety of reagent storage and retrieval can be effectively guaranteed.

[0007] Another objective of this utility model is to provide an intelligent hazardous chemical reagent cabinet, which can automatically record core information such as the person storing or retrieving the reagent, the storage or retrieval time, and the name and quantity of the reagent stored or retrieved, through the setting of a face recognition unit, an RFID identification unit, and a weighing platform.

[0008] To achieve the above objectives, this utility model provides an intelligent hazardous chemical reagent cabinet for storing solid and liquid reagents, comprising at least: a layered reagent bottle storage area, which is a multi-layered reagent bottle storage area within the cabinet, with the upper area being the solid storage area and the lower area being the liquid storage area; each layer of the storage area has a groove for placing the reagent bottle with a size adapted to the bottom of the bottle; a slide rail gripper assembly, which includes at least one vertically arranged first slide rail and multiple horizontally arranged second slide rails adapted to the number of layers in the storage area; the gripper is hinged to the slide rail and slides on the slide rail, stopping and releasing or clamping when the gripper slides to the corresponding position for storing or retrieving the reagent bottle; and a leakage detection unit, which is located at the bottom of the liquid storage area, for monitoring and issuing an early warning when liquid hazardous chemicals drip during the storage or retrieval of liquid reagent bottles.

[0009] Furthermore, in the above technical solution, the hinge may be provided with a two-position limiting structure, so that the gripper is always in the horizontal direction when it slides on the first or second slide rail.

[0010] Furthermore, in the above technical solution, the reagent storage and retrieval window of the reagent cabinet door may be equipped with: a weighing platform, which is used to record the weight of the reagent bottle when it is stored or retrieved; and an RFID identification unit, whose radio frequency reader is set above the weighing platform and above each storage position in the reagent bottle layered storage area, for identifying the electronic tags affixed to the reagent bottles to obtain reagent category and name information.

[0011] Furthermore, in the above technical solution, the reagent cabinet door may be equipped with a face recognition unit, which is set up with two people and two locks, and is used to identify the information of the person storing and retrieving the reagents.

[0012] Furthermore, in the above technical solution, the reagent cabinet door may also be equipped with: a control unit, which can be used to receive information read and authenticated by the facial recognition unit and control unlocking; obtain the required reagent name through the search command bar; and receive identification information from the RFID identification unit and control the gripper to grasp the reagent bottle, slide it along the slide rail, and release the reagent bottle. The control unit can also be used to receive weight data from the weighing platform and calculate the reagent usage before and after storage. The control unit also has a storage subunit for recording and storing real-time ledgers, access and usage real-time ledgers, and updating and archiving MSDS data.

[0013] Furthermore, in the above technical solution, the top of the reagent cabinet can be equipped with ventilation equipment for 24-hour ventilation inside the cabinet.

[0014] Furthermore, in the above technical solution, the solid storage area can be divided into two layers with a total of four layers; the liquid storage area can also be divided into two layers with a total of four layers; the height of each storage layer is 30-40cm.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1) This utility model can classify and store hazardous chemicals of different states and types by dividing the reagent cabinet into sections; by cooperating with the slide rail gripping assembly and the reagent bottle storage positions set in the partitioned and layered configuration, the gripping can be automatically gripped and released as needed, and after the gripping clamps hold the mouth of the reagent bottle, it can slide on the vertical and horizontal slide rails to transport the reagent bottle to the storage window or the designated storage location.

[0017] 2) This invention, through the inclusion of a leakage detection unit, can issue an early warning message immediately when leakage occurs during reagent bottle storage and retrieval, facilitating timely manual intervention. The zoning of the reagent cabinet, the coordinated use of the slide rail gripping assembly, and the leakage detection unit work synergistically to effectively ensure the stability and safety of reagent storage and retrieval.

[0018] 3) The gripper and slide rail of this utility model are connected by a hinge. The two-position limiting structure of the hinge can ensure that the gripper is always in a horizontal position when it slides on the first or second slide rail, so as to ensure the horizontal state of the reagent bottle mouth and prevent it from tipping over.

[0019] 4) This utility model can receive data from the face recognition unit, RFID identification unit and weighing platform through the control unit, and can automatically record core information such as the user, access time, name of the reagent and amount of reagent used.

It can also automatically download MSDS according to the name of the reagent, update it automatically, and call up the MSDS of any reagent at any time as needed, reducing the burden on the administrator. It is both intelligent and efficient.

Detailed Implementation

[0030] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0031] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0032] In this document, for ease of description, spatial relative terms such as “below,” “under,” “down,” “above,” “above,” “upper,” etc., are used to describe the relationship of one element or feature to another element or feature in the accompanying drawings. It should be understood that spatial relative terms are intended to encompass different orientations of an object in use or operation, in addition to those depicted in the figures. For example, if an object in the figure is flipped, an element described as “below” or “under” another element or feature would be oriented “above” that element or feature. Thus, the exemplary term “below” can encompass both the downward and upward orientations. An object may also have other orientations (rotated 90 degrees or other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0033] In this document, the terms "first," "second," etc., are used to distinguish two different elements or parts, and are not used to define specific positions or relative relationships. In other words, in some embodiments, the terms "first," "second," etc., can also be used interchangeably.

[0034] like Figures 1 to 5 As shown, this utility model provides an intelligent hazardous chemical reagent cabinet 100 for storing solid and liquid reagents, including at least a reagent bottle layered storage area, a slide rail gripping assembly 5, and a leakage detection unit 7. The reagent bottle layered storage area is a multi-layered reagent bottle storage area within the reagent cabinet. Figure 4 The diagram illustrates four layers. The upper area (the top two layers) is a solid storage area (including four solid reagent storage platforms 3, zones 1-4), and the lower area (the bottom two layers) is a liquid storage area (including four liquid reagent storage platforms, zones 5-8). Each storage layer has a groove (not shown) at the reagent bottle placement position that matches the bottle bottom size, which helps stabilize the reagent bottles during storage. The slide rail gripper assembly 5 includes at least one vertically arranged first slide rail 51 and multiple horizontally arranged second slide rails 52 adapted to the number of storage layers. The gripper 50 is connected to the slide rail via a hinge (not shown) and slides on the slide rail (i.e., it can slide freely on the first slide rail 51 and the second slide rail 52). When the gripper 50 slides to the corresponding position for storing or retrieving the reagent bottle, it stops sliding and releases or clamps, used for storing and retrieving the reagent bottle. The hinge may have a two-position limiting structure (not shown in the figure). When the gripper 50 slides on the first slide rail 51 or the second slide rail 52, the gripper remains horizontal to ensure the reagent bottle opening is level and prevent tipping. A leakage detection unit 7 is located at the bottom of the liquid storage area to monitor for leaks of liquid reagent bottles and provide an early warning when liquid hazardous chemicals are spilled. To ensure ventilation, a ventilation system 6 may be installed on the top of the reagent cabinet 100 for 24-hour ventilation.

[0035] By adopting the above technical solution, this utility model can classify and store hazardous chemicals of different states and types through reagent cabinet partitioning (i.e., multiple solid zones at different positions in the upper part and multiple liquid zones at different positions in the lower part). Through the cooperation of the sliding rail gripper assembly and the partitioned reagent bottle storage positions, the gripper can automatically grab and release as needed. After the gripper holds the reagent bottle mouth, it can slide on vertically and horizontally arranged sliding rails, thereby transporting the reagent bottle to the storage window or designated storage location. The leakage detection unit can issue an early warning message immediately if leakage occurs during reagent bottle storage, facilitating timely manual intervention. Therefore, the reagent cabinet partitioning, the coordinated use of the sliding rail gripper assembly, and the leakage detection unit can effectively ensure the stability and safety of reagent storage and retrieval.

[0036] Further as Figure 1 , 3 As shown, the reagent cabinet door 101 has a weighing platform and an RFID identification unit at the reagent storage window 2. RFID is an abbreviation for Radio Frequency Identification. The weighing platform 21 is used to record the weight of the reagent bottles when they are stored (i.e., the weight before and after use). The RFID readers 22 / 4 in the RFID identification unit are located above the weighing platform 21 (i.e., at the position of the first RFID reader 22) and above each storage position in the reagent bottle layered storage area (i.e., at the position of the second RFID reader 4). They are used to identify the electronic tags affixed to the reagent bottles to obtain reagent category and name information.

[0037] Further as Figure 1 , 2 As shown, a facial recognition unit 11 is installed on the reagent cabinet door 101. This facial recognition unit 11 is preferably configured with a dual-person, dual-lock system to identify the information of the person accessing the reagents. Two users must scan their faces together to unlock the cabinet. A control unit 1 is also installed on the reagent cabinet door. This control unit 1 can receive information read and authenticated by the facial recognition unit 11 and control the unlocking; it can also retrieve the desired reagent name through the search command bar; and it can receive identification information from the RFID identification unit and control the gripper to grasp the reagent bottle, slide it along the slide rail, and release the reagent bottle. In addition, the control unit is also used to receive weight data from the weighing platform 21 and calculate the amount of reagent used before and after access. Further reference... Figure 2 The control unit 1 is equipped with a storage subunit 13 for recording and storing real-time ledgers, accessing and using real-time ledgers, and updating and archiving MSDS data. MSDS is an abbreviation for Material Safety Data Sheet.

[0038] This utility model can receive data from a face recognition unit, an RFID identification unit, and a weighing platform through a control unit, and can automatically record core information such as the person who accesses the reagent, the access time, the name of the reagent and the amount of reagent used. It can also control the movement of the slide rail gripper assembly to realize the automatic access of reagent bottles.

[0039] The height of the intelligent hazardous chemical reagent cabinet of this utility model is preferably 150-200cm, and the width is 100-150cm. It preferably includes 8 compartments (i.e., Figure 4 It has 4 solid storage areas and 4 liquid storage areas; the height of each storage area is preferably 30-40cm.

[0040] When using the reagent cabinet, the user can enter the name of the required reagent in the search command bar 12. The control unit 1 and the RFID identification unit locate the reagent bottle according to the reagent name and send a command to control the gripper 20 to move to the required reagent location via the slide rail and pick up the reagent bottle to weigh it on the weighing platform 21 at the storage window 2. The user can then take the reagent from the storage window 2. When returning the reagent, the user only needs to place the reagent bottle on the weighing platform 21. After weighing, the RFID identification unit uploads the name of the electronic tag on the reagent bottle to the control unit 1. The control unit sends a command to activate the slide rail gripper assembly to pick up the reagent and return it to its position. At the same time, the facial recognition unit 11 uploads data such as the user's name and storage time. The weighing platform 21 sends parameters such as the weight of the reagent before and after use to the control unit for usage calculation. The usage can be recorded in the storage and access real-time ledger and the storage real-time ledger through the storage subunit 13. If storing new reagents, the reagent bottle with the electronic tag can also be placed on the weighing platform 21, and the storage real-time ledger will be recorded according to the name of the reagent, the name of the person storing it, the time, and the quantity stored. The control unit can perform an online MSDS update once a year and record it in the real-time MSDS archive.

[0041] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical applications, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. Any simple modifications, equivalent changes, and alterations made to the foregoing exemplary embodiments should fall within the protection scope of the present invention.
