Description

Technical Field

[0001] The utility model relates to the field of intelligent warehouse management, in particular to a material management shelf. Background Art

[0002] With the popularization of computer applications, most companies have begun to use computer data management systems for warehouse management data. However, many warehouses still use the traditional method of manual recording and manual input into the computer to collect and manage statistical data. Not only is the input speed slow and the accuracy low, it also causes a lot of waste of labor resources, making it difficult to meet the warehouse's management of a variety of materials, seriously affecting the company's work efficiency and restricting the company's healthy development.

[0003] In order to solve the above problems, management shelves based on RFID technology have emerged in the current warehouse management work. It can automatically collect data from the work links such as goods entering, leaving, dispatching, transferring, inventory counting, and arrival inspection, so as to improve the accuracy and speed of data entry in each work link, ensure that the staff can grasp the real data of the goods in a timely and accurate manner, and arrange the inventory reasonably. RFID stands for radio frequency identification. It is a technology that uses radio waves to automatically identify and track tags attached to objects. These tags contain information stored electronically, which can be read from a distance using an RFID reader.

[0004] For example, a Chinese patent document with publication number CN210446408U discloses an intelligent shelf for automatic acquisition of commodity information based on RFID, which includes a shelf body, an MCU microcontroller, an information acquisition module and a display module; the information acquisition module includes devices such as an RFID reader / writer, an RFID antenna and an infrared sensor, which uses the RFID reader / writer and the RFID antenna to automatically acquire the label information of the commodities on the shelf, and uses an infrared sensor to sense whether there are goods in the shelf.

[0005] The above-mentioned smart shelves can automatically determine whether there are goods left on the shelves and the quantity of goods, which improves the convenience and efficiency of management. However, they can only roughly confirm whether there are goods stored on the shelves, the quantity stored, the characteristic information of the goods, and the inventory status. They cannot confirm the specific spatial location of each item and do not have the ability to accurately locate goods in a large space and multiple sources of goods. In the increasingly sophisticated goods management, convenience and efficiency need to be further improved. Utility Model Content

[0006] The purpose of the utility model is to provide a warehouse material management shelf based on RFID, which, with the help of RFID identification technology, can not only confirm the specific information of each incoming and outgoing goods, but also more specifically clarify the storage location of each goods, and realize the positioning and searching function with the help of the management device, thereby greatly improving the efficiency of goods management.

[0007] A warehouse material management shelf based on RFID, comprising a shelf for placing goods and an RFID signal reader for identifying electronic tags, characterized in that the shelf comprises a plurality of horizontally arranged storage boards for storing goods and side panels vertically connected to the storage boards; each of the storage boards is provided with a plurality of storage areas, and each storage area is individually provided with an RFID signal reader; the warehouse material management shelf also comprises a management device electrically connected to all the RFID signal readers and used to collect and process information of placed goods.

[0008] Thus, the rack is used to place the target goods. Each rack can be set as a multi-layer structure according to actual use requirements. The two side panels provide support for multiple storage boards. The storage boards are installed vertically to the side panels, and multiple specific storage areas are arranged on them. Multiple RFID signal readers are arranged at intervals on each storage board. The RFID signal readers are horizontally installed on the upper surface of the storage board and are set corresponding to the storage areas. When goods are placed in the storage area on the storage board, the RFID signal reader will automatically read the information of the goods placed at that position. Since each RFID signal reader is arranged at intervals on the storage board, the storage area corresponding to each RFID signal reader has a unique position code, such as "the number position of the layer board". At this time, no matter which storage position the goods are placed on, they will be assigned a specific position code. The management device can use the MCU microcontroller in the prior art. The MCU microcontroller is a microcomputer system that integrates a central processing unit (CPU), a memory, and an input / output interface. The MCU microcontroller is installed on the rack and is electrically connected to all RFID signal readers installed on the rack through data cables. It collects identification information of each RFID signal reader, clarifies the location code and warehousing time of the goods, and manages the information of all goods placed on the entire rack.

[0009] By reading the information from the above management device, the staff can obtain the precise location of all goods on the shelf and conduct a unified search, which greatly improves the efficiency of goods management.

[0010] As a preferred embodiment of the present invention, a plurality of two-color indicator lights are provided on the lateral edges of the storage plate, and the two-color indicator lights are electrically connected to the management device.

[0011] Therefore, the two-color indicator light adopts an LED lamp body, which can emit red or green light. The LED lamp body is installed on one side edge of the plate body of each storage board, which is electrically connected to the management device and driven by the management device. Each two-color indicator light corresponds to an RFID signal reader, which can display the reading status of the RFID signal reader. For example, when there is a cargo placed on the RFID signal reader of the "second position", the RFID signal reader is in a working reading state, and the two-color indicator light corresponding to the RFID signal reader continuously emits green light; when there is no cargo placed on the RFID signal reader of the "second position", the RFID signal reader is in a non-working state, and the two-color indicator light corresponding to the RFID signal reader does not emit light; when there are multiple cargos placed on the RFID signal reader of the "second position", that is, when the RFID signal reader at this position recognizes multiple electronic tag information, the two-color indicator light corresponding to the RFID signal reader emits red light to remind the staff to make timely adjustments to the cargo placement at this position. Through the setting of the two-color indicator light, the on-site management ability of warehouse managers for cargo can be further improved.

[0012] As a preferred embodiment of the present invention, the warehouse material management shelf also includes a management terminal platform which is interconnected and communicates with the management device and is used to manage and search for cargo information.

[0013] Therefore, the remote management capability can be improved by setting up a management platform. A single warehouse material management shelf is managed by a management device installed on the shelf. When a warehouse contains multiple warehouse material management shelves, unified planning and management can be carried out through the management platform to provide precise positioning and search services for goods in a large space.

[0014] Each management device can be connected to the management platform through network cables or wireless communication means such as WIFI to upload and download data. The management platform is a server and human-computer interaction device equipped with a dedicated management system, which can meet the specific search needs of staff, efficiently and conveniently.

[0015] As a preferred embodiment of the utility model, the storage plate is provided with an EVA cushion layer for shock absorption and anti-slip, and the EVA cushion layer is provided with an accommodating through hole for accommodating the RFID signal reader.

[0016] Due to the wide variety of goods, an EVA cushion is specially set on the storage board for some fragile items. EVA is a polymer material with good elasticity, softness and wear resistance. It is also resistant to high and low temperatures and chemical corrosion. It is attached to the storage board and fixed to meet the placement needs of various goods. At the same time, a through hole for accommodating the RFID signal reader is opened on the EVA cushion to avoid blocking the RFID signal reader and ensure stable identification and reading under various conditions.

[0017] As a preferred embodiment of the present invention, the frame body further includes a top cover plate vertically installed between the side plates, and the top cover plate is located above the topmost storage plate in the vertical direction.

[0018] Thus, the top cover is located above the top shelf in the vertical direction and is vertically connected to the two side panels on both sides. As a top-level protection measure, it can prevent objects from accidentally falling and damaging the goods stored on the top shelf. In addition, the board can also serve as a support platform for placing electronic equipment and other cables of the management device.

[0019] As a preferred embodiment of the present invention, the frame further includes a lower enclosure plate vertically connected to the bottommost storage plate, and a limiting through hole for engaging a mechanical arm of a transport vehicle is provided on the lower enclosure plate.

[0020] Therefore, in the layout of the warehouse, it is usually necessary to move the shelves, and such movement usually requires the use of engineering vehicles such as forklifts. The lower enclosure is vertically connected to the bottom storage board, and a limit hole is opened in the lower enclosure, which can provide a matching limit fixing hole for the mechanical arm of the forklift and other engineering vehicles. The specific form of the limit hole can be customized according to the matching vehicle of the warehouse. It can ensure the relative stability of the vehicle and the shelf when moving the shelf, and improve safety.

[0021] As a preferred embodiment of the present invention, the warehouse material management shelf also includes an LED display component installed on the top cover plate for displaying cargo storage information.

[0022] Therefore, by installing an LED display component on the top cover plate, the storage situation of goods on the warehouse material management shelf can be visualized. The LED display component is specifically an LED display screen, which can display the storage quantity, type of goods, current network status, warehousing time and other information on the shelf in real time, helping managers to quickly understand the specific information of the shelf and further improve management efficiency.

[0023] As a preferred embodiment of the present invention, the EVA cushion layer is covered with a waterproof layer.

[0024] Therefore, since the warehouse material management shelf has a variety of usage environments, the goods used for storage may be used in a humid working environment, and there is a situation where the goods are not wiped properly when entering the warehouse, resulting in water vapor attached to the bottom. When it is placed directly on the shelf, its water vapor may invade the RFID signal reader, causing electrical failure of the RFID signal reader and causing property loss. By covering the EVA cushion with a waterproof layer and selecting soft and wave-transparent materials, the RFID signal reader located in the limit through hole can be protected without affecting signal recognition.

[0025] In summary, the utility model has the following beneficial effects:

[0026] 1. Each storage board is provided with multiple storage areas, and each storage area is individually provided with an RFID signal reader. Through the specific identification positions of multiple RFID signal readers and combined with the management device, the goods placed in different storage areas on the storage board can be located, which is convenient for unified management and search.

[0027] 2. By setting a shock-absorbing and anti-slip EVA cushion layer on the storage board and covering the EVA cushion layer with a waterproof layer, the RFID signal reader can be protected while protecting the goods from being bumped and broken.

[0028] 3. By opening a limit through hole on the lower enclosure, it can be engaged and fixed with the mechanical arm of the transport vehicle to prevent the shelf from shaking and falling during transportation, causing safety accidents.

[0029] 4. An LED display component for displaying the storage information of goods is installed on the top cover of the warehouse material management shelf. The LED display component can visualize the storage situation of the goods, such as the quantity, type, current network status, warehousing time and other information of the goods on the shelf, to help managers quickly understand the specific information of the shelf and further improve management efficiency.
