Description

Technical Field

[0001] This utility model relates to the field of weighing equipment technology, specifically to an intelligent shelf scale. Background Technology

[0002] In the logistics and storage sector, multiple goods are typically categorized and placed on shelves in batches. Staff need to periodically inventory the remaining quantity of goods to understand the circulation and remaining stock. The most common method for inventory is to obtain the quantity of goods by weighing them with electronic scales.

[0003] The prior art discloses a Chinese utility model patent, such as CN220932174U, entitled "An Electronic Platform Scale for Easy Cargo Fixing," which specifically discloses a weighing pan, side plates, a drive mechanism, and a weighing base. Support rods are fixed at the four corners of the top of the weighing base, and the four support rods together support the weighing pan. Four side plates are evenly distributed around the weighing pan, which fix the cargo on top of the weighing pan. The side plates include T-shaped fixed plates and movable plates. Multiple movable plates are provided, and adjacent movable plates are hinged by pins, which are locked by knobs. The lowermost movable plate is also hinged to the T-shaped fixed plate by a pin.

[0004] The above solution, by setting up a drive mechanism and grooves, makes the electronic platform scale more applicable, capable of measuring goods larger than the weighing pan size, and the side plate can adapt to the fixing of irregular goods, solving the problem of poor goods fixing stability and difficulty in fixing goods larger than the weighing pan size in existing electronic platform scales.

[0005] However, in practical applications, even if multiple goods are placed in the same storage box and the box is weighed, staff still need to observe and record the specific types of goods stored in the box, which affects the efficiency of inventory management.

[0006] Therefore, an intelligent shelf scale is proposed to solve the problems mentioned above. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above, diagonally above, or on the surface of the second feature, indicating that the second feature is supported and fixed by the first feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicating that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] The present invention will be further described below with reference to the embodiments.

[0038] Example:

[0039] See attached document Figure 1-6 This embodiment proposes an intelligent shelf scale, including an upper support 1 and a lower support 2. The top of the upper support 1 is provided with a weighing pan 3 for placing the object to be weighed. In use, the object to be weighed is placed on the weighing pan 3. A weight sensor 10 is provided between the upper support 1 and the lower support 2. The weight sensor 10 can measure the weight of the object to be weighed.

[0040] It also includes a shelf 6, which is placed on top of the weighing pan 3.

[0041] For some identical objects to be weighed, weighing each one individually and then totaling the weights is too cumbersome. In this example, multiple objects to be weighed can be placed in a box-shaped structure that can be identified. The lower support 2 is detachably connected to the lower part of the upper support 1 and is set parallel to the upper support 1. The upper support 1 is equipped with a sensing unit that can identify different racks 6 on which objects to be weighed are placed. The upper surface of the weighing pan 3 is horizontally arranged and a sensing hole 31 is opened on its end surface. The sensing unit includes an information acquisition sensing piece 4 that can collect information about the objects to be weighed. The sensing end of the information acquisition sensing piece 4 is set directly opposite the sensing hole 31.

[0042] The information collection sensor 4 can be identified in various ways. For example, different distinguishing features can be set on the bottom surface of different shelves 6, such as QR codes. The information collection sensor 4 can be set to various methods such as visual acquisition and QR code recognition. When the shelf 6 is placed on the weighing pan 3, the distinguishing features on its bottom will be collected by the information collection sensor 4, so that the total weight of the objects in the shelf 6 can be obtained in the form of data.

[0043] In addition, an inventory alert function can be set up in the server backend, which can realize advance preparation of goods and inventory management, bringing cost-saving and efficiency-enhancing functions to the factory warehouse and reducing the risk of traditional factory material inventory.

[0044] In this embodiment, the distinguishing feature of the bottom of the shelf 6 is an RFID (Radio Frequency Identification) coil chip, and the information acquisition sensor 4 has a reader / writer unit (including an RFID identification module and an ID conversion format module) that can emit electromagnetic wave signals. When the electromagnetic wave signal emitted by the information acquisition sensor 4 is received by the RFID coil chip, it will be activated and send its own identification code and memory data through the built-in antenna. After the antenna of the information acquisition sensor 4 receives the electromagnetic wave signal sent by the RFID coil chip, it will transmit it to the signal processing unit inside the information acquisition sensor 4 and parse these signals to obtain the identification code and memory data of the RFID coil chip. The specific data processing method is a known technology and will not be described in detail here.

[0045] It is worth noting that this embodiment also includes a bottom shell 5, and a lower bracket 2 is detachably mounted on the bottom shell 5. A PCB board 51 that is electrically connected to the weight sensor 10 and the information acquisition sensor 4 is located inside the bottom shell 5.

[0046] In this embodiment, the PCB board 51 is a microcontroller. When the information acquisition sensor 4 obtains the identification code and memory data of the shelf 6 and the weight obtained by the weight sensor 10, the PCB board 51 will obtain the total weight and distinguishing features of the shelf 6.

[0047] This allows for the collection of weights from multiple objects in different batches, enabling batch statistics to be performed on multiple shelves 6 containing different types of materials. In this embodiment, a Wi-Fi module can be integrated on the PCB board, allowing these data to be wirelessly transmitted to the cloud server, eliminating the need for manual data statistics and enabling unmanned monitoring of inventory levels.

[0048] In addition, statistics can also be performed via wired means. In this embodiment, a data line 54 electrically connected to the PCB board 51 is also provided on the side end face of the bottom shell 5. The data line 54 can be connected to the calculator to realize automatic data upload. In addition, the measurement data can also be adjusted through the connected device. This is a well-known technology and will not be described in detail here.

[0049] The bottom shell 5 has a switch 52 and a charging hole 53 that are electrically connected to the PCB board 51 on its side surface.

[0050] In this embodiment, the sensing end of the information acquisition sensor 4 is parallel to the upper surface of the weighing pan 3 and passes through the sensing hole 31. The upper plane of the information acquisition sensor 4 is lower than the upper plane of the weighing pan 3. Therefore, when the shelf 6 is placed on the upper surface of the weighing pan 3, it will not directly contact the information acquisition sensor 4, thus avoiding damage to the information acquisition sensor 4 and also maintaining a certain distance between the information acquisition sensor 4 and the RFID (Radio Frequency Identification) coil chip on the shelf 6 being tested.

[0051] Optionally, the upper bracket 1 is in the shape of a rectangular plate with several strip grooves on its surface. A recessed platform is provided in one of the strip grooves. The sensing unit also includes a sensing plate fixing plate 11 fixed to the recessed platform by screws. The information acquisition sensing plate 4 is fixed to the sensing plate fixing plate 11 by screws.

[0052] In addition, to ensure good pressure bearing and shock absorption between the upper support 1 and the lower support 2, EVA foam 12 is provided between the upper support 1 and the lower support 2. Both the upper and lower ends of the EVA foam 12 have adhesive layers. When the equipment has been used for a long time, the EVA foam 12 can be replaced.

[0053] The EVA foam 12 is attached between the upper bracket 1 and the lower bracket 2, creating a certain gap between them. The overall shape of the EVA foam 12 is not specifically limited; it can be set around the contact area between the upper bracket 1 and the lower bracket 2, or several strips can be set, with the strips of EVA foam 12 arranged at equal intervals along the length or width of the upper bracket 1.

[0054] In addition, to ensure the best weighing and identification results, the staff can accurately place the shelf 6 in the center of the weighing pan 3. The scale lines are opened on the upper surface of the weighing pan 3 along the diagonal of the weighing pan 3, so that the center position of the weighing pan 3 can be quickly determined and the position of the shelf 6 can be selectively adjusted when placing it.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
