Description

[0001] This application is a divisional application of Chinese utility model patent application No. 2025224119105, filed on November 13, 2025, entitled "A Modular Intelligent Seal Document Management Cabinet". Technical Field

[0002] This utility model relates to intelligent IoT seal file cabinets, and specifically to a file cabinet for modular intelligent seal file management cabinets. Background Technology

[0003] As government agencies, enterprises, and public institutions continue to expand and have numerous branches, the management of seals and documents faces increasingly stringent requirements. Currently, the management model for corporate seals and documents in these organizations typically involves centralized stamping at headquarters or designated personnel at subsidiaries, which leads to numerous inconveniences in seal usage. Company seals and documents play a crucial role; lax control can have serious consequences, causing significant problems for the standardized use of seals within the company. Furthermore, existing seal and document management models are inefficient and costly, wasting considerable time, impacting work efficiency, and hindering business growth.

[0004] Traditional seal cabinets use mechanical principles to lock a large number of seals in the cabinet with mechanical keys. The records of seal storage and retrieval are greatly affected by human factors, making it easy to omit or misrecord information. Incomplete records lead to difficulties in searching, and the correlation between seal retrieval records and stamping events is poor, making it inconvenient to search and trace. Seal storage and retrieval must be supervised by someone, and once the person leaves, the seals cannot be stored or retrieved, affecting work efficiency. When seals are stored together, storage and retrieval can easily become chaotic, or even the wrong seal can be retrieved, posing a security risk. When storing a large number of seals, it is difficult to quickly find the required seal, which is time-consuming and laborious. The real-time status of seal storage or retrieval is inconvenient to check. The person retrieving the seal may only find out that the seal has been taken when they arrive at the storage location, wasting time. There is no dedicated monitoring of the seal storage and retrieval process, which poses a significant security risk. When using smart seals, if the administrator does not charge them in time, the battery may be insufficient, affecting normal stamping. Utility Model Content

The main stamp cabinet 1, auxiliary stamp cabinet 2, or document cabinet 3 automatically opens the drawer 4 containing the stamp or the cabinet door 302 containing the document. The document is indicated by a flashing tag. After the operator retrieves the stamp or document, the drawer 4 or cabinet door 302 is closed.

[0077] When the operator returns the seal or document, the seal or document is read using an RFID scanner. The control board then controls the opening of the corresponding drawer 4 and file cabinet 3 door 302. The status detection module of the industrial control computer detects whether the seal has been returned to drawer 4 or file grid 305, and whether the drawer 4 or file cabinet 3 door 302 is closed. If both are correct, the system displays that the seal return process is complete. If the status detection module detects that the seal has not been placed in the drawer or that the cabinet door 302 cannot be closed, even if it is forcibly closed, the cabinet door 302 will automatically open again, and the touch screen will remain on the seal return page without switching pages until the operator correctly returns the seal or document. If the seal or document is returned but drawer 4 or cabinet door 302 is not closed, the touch screen will remain on the seal or document return page without switching pages. In either of the above two scenarios, if drawer 4 or cabinet door 302 is not properly closed within the specified time, the system will broadcast a voice reminder via the speaker. After several rounds of voice broadcasts, the system will push a reminder message to the administrator via the network. Only after drawer 4 or cabinet door 302 is properly closed can the next step, such as retrieving or returning the seal or retrieving and storing documents, be performed.

[0078] In the event of a power outage or other special circumstances, the emergency door opening device will be activated to open or close drawer 4 or filing cabinet 3 door 302. The emergency unlocking device, i.e., the mechanical key, is kept by the administrator and is used to open all drawers; each stamp compartment 409 is equipped with an emergency unlocking device for opening each stamp compartment 409.
