Description

Technical Field

[0001] This utility model relates to the field of material sorting, specifically to a visual material sorting workstation. Background Technology

[0002] In traditional warehouse management, the sorting and retrieval of materials relies heavily on manual operation. This limitation becomes increasingly apparent, especially during the upgrade to intelligent warehouses. Operators must use paper documents or handheld terminals to locate materials, manually verify inventory information, and sort the target materials one by one. Manual sorting requires frequent travel between shelves and workstations. Especially in large warehouses with diverse material types, operators spend a significant amount of time locating target bins and are susceptible to fatigue and environmental interference, leading to fluctuations in sorting efficiency.

[0003] Furthermore, the surge in tasks during peak periods necessitates the temporary deployment of additional manpower, further increasing operating costs. Material retrieval relies on operators' real-time memory of inventory data or secondary verification, which is prone to errors, omissions, or duplicate retrievals due to delayed information updates, such as the system inventory not promptly synchronizing with the actual retrieval status. For instance, when multiple people are working collaboratively, if a material bin is taken but the system status is not immediately updated, subsequent personnel may continue to try to find that material, resulting in wasted time and process chaos.

[0004] Against this backdrop, there is an urgent need for a new visual material sorting workstation that can solve the problem of low efficiency in sorting materials in the traditional model. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a visual material sorting workstation that enables efficient storage and sorting of materials.

[0017] In the diagram, 1 is the support component, 2 is the partition, 3 is the material box, 4 is the mounting plate, 5 is the display screen, 6 is the support plate, and 7 is the back plate. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solution of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and a preferred embodiment.

[0019] This embodiment provides a visual material sorting workstation, including an AGV trolley, a support component 1, partitions 2, material boxes 3, a mounting plate 4, a communication module, a power module, and a display screen 5. Partitions 2 are fixedly connected to the support component 1. Multiple partitions 2 are provided, each with a fixed positioning groove. Multiple partitions 2 form a multi-layered load-bearing structure. Material boxes 3 are placed on the partitions 2. The bottom of each material box 3 has a protrusion matching the positioning groove. An RFID tag containing material information is affixed to the body of the material box 3. The AGV trolley is equipped with an RFID reader, which reads the information from the RFID tags. The AGV trolley's main control unit communicates with the RFID reader. The trolley's main control unit also communicates with a warehouse management system (WMS), enabling the WMS to receive material information obtained from the RFID tags by the RFID reader. The mounting plate 4 is fixedly connected to the top of the support component 1. The communication module and power module are embedded within the mounting plate 4. The display screen 5 is fixedly connected to the mounting plate 4 and connected to the power module. The display screen 5 and the warehouse management system are connected via the communication module.

[0020] like Figure 1 As shown in the figure, only the connection relationship of support 1, partition 2, material box 3, mounting plate 4 and display screen 5 is shown. Support 1 consists of multiple support plates 6 and a back plate 7. The multiple support plates 6 are distributed at intervals along the horizontal direction. The back plate 7 is fixedly connected to all support plates 6. There are two partitions 2. Both partitions 2 are used to place material boxes 3. The partitions 2 are made of high-strength aluminum alloy and the surface is treated with anti-slip and wear-resistant materials to accommodate material boxes 3 of different weights and shapes. Mounting plate 4 is fixedly connected to the top of support 1. Display screen 5 is fixedly connected to mounting plate 4.

[0021] Specifically, the material information written into the RFID tag includes the entry and exit status of material box 3, storage location, material type, and quantity data.

[0022] The AGV is equipped with an RFID reader at its bottom and includes a main control unit. The RFID reader and the main control unit are connected for communication. A telescopic robotic arm is installed at the top, and an electromagnetic chuck is installed at the end of the robotic arm. The electromagnetic chuck is used to grasp the material box 3. The AGV is configured with an existing navigation module and a preset program to achieve positioning and path planning to reach the material box 3, and to issue instructions to the main control unit of the AGV. The robotic arm adopts a known robotic arm control method to grasp the material box at the corresponding storage location and store the material box in the preset storage location. All related programs of the AGV are existing technologies, and the above-mentioned functions required by the AGV in this embodiment can be achieved by existing technologies.

[0023] Engineering verification shows that the reading area of ​​the RFID reader on the AGV is set to be less than or equal to 30 centimeters vertically from the material box 3, which can ensure that the AGV can quickly read the RFID tag information.

[0024] The workflow of this embodiment:

[0025] RFID tags containing material information are affixed to the body of material box 3. The material box 3 and partition 2 are secured together by the interlocking of positioning grooves and protrusions on the partition 2. Multiple partitions 2, together with support member 1, enable efficient storage of materials. The AGV (Automated Guided Vehicle) travels using its existing navigation module and preset program. When it reaches the reading area of ​​its onboard RFID reader, the RFID reader can read the RFID tag information on each material box 3, obtaining the material information, including: inbound / outbound status, storage location, material type, and quantity. The RFID reader outputs the material information to the AGV's main control unit. After the AGV retrieves the material box, its main control unit outputs the corresponding material information to the warehouse management system (WMS). The WMS then updates the inbound / outbound status of the materials. The warehouse management system (WMS) is an operational software system for warehouse management, such as an ERP system. It includes common functions such as inbound and outbound management, inventory management, order management, product management, acquisition tracking, and inventory counting. It optimizes and improves warehouse operation processes and inventory management efficiency. The display screen shows the status of material inbound and outbound tasks, such as the task status changing from "outbound in progress" to "outbound completed", or using different colors to indicate the status of inbound and outbound tasks, such as red light indicating "outbound in progress", green light indicating "outbound completed", yellow light indicating "inbound in progress", and blue light indicating "inbound completed". Parts not involved in this embodiment adopt existing technologies.

[0026] This embodiment only describes the outbound process; the inbound process is similar.

[0027] This embodiment improves space utilization by using multi-layer partitions, making full use of space and increasing the storage capacity per unit area. The positioning grooves are used to fix the material boxes to ensure storage stability. By increasing storage density, the travel distance of the AGV is reduced and the path complexity is decreased, thereby further improving sorting efficiency based on the AGV and RFID.

[0028] This embodiment mentions the use of the AGV cart control unit and the warehouse management system (WMS system), which inevitably requires computer program algorithms to implement their corresponding functions. However, existing computer program algorithms can achieve the functions to be achieved by this utility model. The innovation of this utility model patent lies in the improvement of the hardware structure. The positioning grooves on each partition 2 can fix the material box 3, ensuring its stable placement on the support 1 and improving the storage density. This improvement reduces the movement distance of the AGV cart based on AGV cart and RFID, enabling the AGV cart to quickly and accurately find and grab the target material box 3, further improving sorting efficiency.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications are also within the protection scope of the present utility model.
