Description

Technical Field

[0001] This application relates to the field of electronic scale technology, and in particular to a device for identifying and weighing laboratory sample bottles. Background Technology

[0002] In modern laboratory management, the storage and use of reagents and hazardous chemicals are crucial for ensuring experimental safety and efficiency. With the expansion of laboratories and the increasing demands for management, traditional reagent management methods have gradually revealed numerous shortcomings, such as low efficiency, error-proneness, and difficulty in achieving real-time monitoring and traceability through manual recording. In recent years, Radio Frequency Identification (RFID) technology has been increasingly introduced into laboratory management, with some laboratories beginning to use RFID chip tags on reagent bottles. These tags can store a wealth of information, including reagent name, specifications, and shelf life, and can quickly identify reagents through contactless reading, significantly improving management efficiency and accuracy.

[0003] However, in existing management processes, laboratories typically employ the following method: when staff retrieve reagents or hazardous chemicals from the cabinet, they must first use an RFID handheld reader to scan the RFID chip on the reagent or hazardous chemical bottle to identify it. Subsequently, staff must place the reagent or hazardous chemical on a balance for weighing. This step-by-step management method not only increases the number of steps but may also lead to low work efficiency. Furthermore, in situations involving multiple bottles where errors are prone to occur, human factors can easily cause confusion in identification and weighing, resulting in inaccurate management of reagents and hazardous chemicals.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "including," "comprising," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0027] In one embodiment, such as Figure 1 As shown, a laboratory sample bottle identification and weighing device is provided. The device includes: a weighing balance, an RFID antenna plate, and a support body; the weighing balance includes a weighing body, a balance tray, and a decorative panel.

[0029] The balance tray includes a rectangular top panel (21) and four first side rectangular plates (22) connected to the four sides of the rectangular top panel; the rectangular top panel (21) and the first side rectangular plates (22) of the balance tray form a cuboid structural frame; an opening is provided in the middle of the rectangular top panel (21);

[0030] The support body includes a rectangular bottom panel (41) and four second side rectangular plates (42) connected to the four sides of the rectangular bottom panel (41); the rectangular bottom panel (41) and the second side rectangular plates (42) of the support body form a cuboid structural frame; an RFID antenna plate (5) is fixedly installed in the middle of the rectangular bottom panel (41); the support body is fixed to the upper surface of the weighing body; the RFID antenna plate is connected to the controller line in the weighing body;

[0031] The outer dimensions of the four first side rectangular plates (22) of the balance tray are larger than the outer dimensions of the four second side rectangular plates (42) of the support body (4), so that the inner cavity of the balance tray composed of the first side rectangular plates (22) is fitted outside the inner cavity of the support body composed of the second side rectangular plates (22); the center of the RFID antenna plate (5) coincides with the center of the opening in the middle of the rectangular top panel (21);

[0032] The balance tray is made of metal, and the decorative panel (1) is a flat plastic panel; the decorative panel (1) is fixed on the rectangular top panel (21) of the balance tray.

[0033] In this embodiment, the weighing body is the same as that of a regular electronic scale, used to weigh the objects placed on it. The built-in RFID antenna and bracket are placed outside the weighing body and do not come into contact with the elastic elements of the weighing body, so they do not affect the weighing results. The built-in RFID antenna (5) emits RFID signals through the square hole in the middle of the balance tray to read the RFID information of reagents and hazardous chemicals. After obtaining the information, it is directly transmitted back to the intelligent cabinet control system and automatically recorded.

[0034] In the aforementioned reagent bottle identification and weighing device, an RFID antenna plate (5) is fixedly installed in the middle of the support body and connected to the controller of the bottom weighing body. The support body includes a rectangular bottom panel (41) and four second side rectangular plates (42) connected to the four sides of the rectangular bottom panel (41), forming a cuboid structural frame. This cuboid structural frame is fitted onto the balance tray. An opening is provided in the top rectangular top panel (21) of the balance tray fitted onto the support body, so that the identification signal emitted by the RFID antenna plate (5) can be emitted from the opening, and not from all four sides. The decorative plate (1) is made of plastic and is located on the rectangular top surface (21) of the balance tray, so that the identification signal emitted by the RFID antenna plate (5) passes through the opening of the rectangular top panel and through the decorative plate (1), accurately identifying the RFID chip information of the reagent bottle placed on the balance tray. At the same time, the weighing body and weighing sensor located at the bottom can weigh the reagent bottle placed on the decorative plate. Therefore, weighing and identification can be performed simultaneously, reducing operational steps, improving work efficiency, and obtaining both identification and weighing results at the same time, which is less likely to cause confusion and greatly increases the accuracy of information management.

[0035] In one embodiment, a groove is provided in any of the second side rectangular plates (42) of the support body that are connected to the long side of the rectangular top panel (21) of the balance tray, and the groove is used for wiring.

[0042] In this embodiment, the weight information and RFID identification results are displayed on a screen so that the experimenter can obtain both weight and identity information simultaneously without confusion.

[0043] In one embodiment, the area of ​​the opening in the middle of the rectangular top panel (21) is larger than the area of ​​the RFID antenna plate (5).

[0044] In this embodiment, the controller directly sends the weight and RFID identification results to the remote device, thereby enabling the remote device to record automatically without confusing the information and improving the accuracy of information management.

[0045] In one embodiment, the area of ​​the opening in the middle of the rectangular top panel (21) is larger than the area of ​​the RFID antenna plate (5).

[0046] In this embodiment, the RFID antenna plate (5) can be fully exposed in the opening in the middle of the rectangular top panel (21), thereby ensuring that the signal emitted upward by the RFID antenna plate passes through the opening completely to accurately identify the RFID chip of the reagent bottle placed on the decorative panel.
