Description

[0002] With the rapid development of high-speed wireless communication technologies such as 5G and Wi-Fi 7, high-precision crystal oscillator components are increasingly used in various electronic devices. As a key material in the manufacture of crystal oscillator components, the performance of conductive silver glue has a direct impact on the overall performance and service life of the crystal oscillator components. However, the performance of conductive silver glue is easily affected by fluctuations in storage conditions. Improper storage methods will not only destroy the original uniform distribution state between silver particles and the polymer matrix, but may also induce adverse internal stress inside the silver glue, thereby causing the fluidity and viscosity of the silver glue to be unstable. Therefore, how to effectively ensure the performance stability of conductive silver glue during storage has become a key issue that needs to be urgently solved in the field of high-precision crystal oscillator component manufacturing.

[0003] At present, the storage management of conductive silver paste mostly still relies on traditional manual records and periodic inspections.

[0020] In this embodiment, the data management system 30 is connected through the intelligent recognition system 10, the environmental control system 20, the positioning and picking system 40, the early warning system 50 and the user management system 60. The intelligent recognition system 10 is used to record the information of the conductive silver paste and upload it to the data management system 30 in real time. The temperature data and humidity data of the storage area of ​​the silver paste are regularly collected through the environmental control system 20 and transmitted to the data management system 30 in real time.

[0021] In one embodiment, the intelligent identification system 10 includes an RFID electronic tag 11 and an RFID reader 12, and the RFID electronic tag 11 matches the RFID reader 12; the RFID electronic tag 11 stores label information of the silver glue model, batch number, storage location, production date and warehousing date; the RFID reader 12 is used to identify and read the RFID tag information, and transmit it to the data management system 30 in real time through a preset interface.

[0022] Specifically, the intelligent identification system 10 includes an RFID electronic tag 11 and an RFID reader 12, which are used for tag presetting, reader deployment and identification, and data verification and transmission. The RFID electronic tag 11 is matched with the RFID reader 12, and the RFID electronic tag 11 stores key information such as the silver paste model, batch number, storage location, production date, and storage date of the conductive silver paste.

[0023] The steps of label presetting are as follows: before the conductive silver glue container is put into storage, the RFID tag is glued to its designated position to ensure that the label is complete and the information encoding is correct, which serves as the basis for automatic identification.

[0024] The deployment and identification steps of the reader are as follows: deploy RFID readers 12 at the entrance, exit and key locations of the storage device to ensure that the label information of all conductive silver glue containers can be fully covered and read. After the container is placed, the conductive silver glue information is read in real time through non-contact communication between the RFID reader 12 and the RFID electronic tag 11, including but not limited to the silver glue model, batch number, production date and warehousing date.

[0025] The steps of data verification and transmission are as follows: after obtaining the information obtained by the RFID reader 12, strictly verify the integrity and format of the data information, eliminate invalid or erroneous data, and after confirmation, transmit the data information in real time to the data management system 30 through a preset interface, such as WiFi, an effective network, etc., for subsequent processing and analysis.

[0026] In one embodiment, the environmental control system 20 includes a temperature control module 21 and a humidity control module 22; the temperature control module 21 includes a plurality of temperature sensors evenly distributed inside the storage area, for real-time monitoring and recording the storage environment temperature; the humidity control module 22 includes a humidity sensor arranged in the storage area, for real-time detection of the humidity level of the storage environment.

[0028] Among them, the temperature control module 21 is integrated with a high-precision temperature sensor, and multiple temperature sensors are evenly distributed inside the storage area of ​​the conductive silver paste, which monitors and records the ambient temperature in real time, and transmits the temperature data to the data management system 30 by wired or wireless means for further analysis and regulation, and automatically adjusts according to a preset temperature range, such as adjusting the cooling power of the storage device to turn on or enhance the cooling function, to ensure that the conductive silver paste is always in its optimal temperature range, and effectively prevent performance changes caused by temperature fluctuations.

[0029] The humidity control module 22 is equipped with a high-precision humidity sensor for continuously monitoring the humidity conditions of the storage environment to protect the quality of the silver glue from humidity fluctuations. The module can accurately capture changes in environmental humidity to ensure that the silver glue storage environment is maintained within an appropriate humidity range to ensure its long-term stability. In addition, humidity data can also be synchronously transmitted to the data management system 30 to provide data support for the optimization and adjustment of environmental conditions.

[0030] In one embodiment, the data management system 30 includes a database module 31 and a data processing module 32; the database module 31 is used to store silver glue properties and environmental parameters; the database module is used to store silver glue properties and environmental parameters; the data processing module 32 is used to process and analyze data, and update inventory data based on the analysis results.

[0031] Specifically, the data management system 30 is the core of the intelligent management and control system, including a database module 31 and a data processing module 32, which are used for data storage, deep processing and intelligent analysis. It integrates data from multiple sub-modules such as the intelligent identification system 10 and the environmental control system 20, and uses efficient data processing algorithms to achieve refined tracking and real-time dynamic management of the entire life cycle information of the conductive silver glue.

[0032] Among them, the database module 31 is a data aggregation center, which is used to collect and store information from all relevant data sources such as the intelligent identification system 10 and the environmental control system 20, establish a conductive silver paste information library, an environmental parameter library, etc., for centralized storage of various types of data, and provide basic information for data processing and analysis by recording core data such as the property specifications of the conductive silver paste and environmental monitoring parameters.

[0033] The data processing module 32 is used to automatically process and analyze the data in the database, such as inventory sorting, validity period calculation, environmental parameter statistics, etc., and use preset algorithms and logical rules to accurately classify, efficiently sort, flexibly screen and deeply count the data, and generate corresponding reports and warning information based on the analysis results to support key functions such as refined inventory management and early warning mechanism triggering. In inventory management, intelligent sorting can be performed based on key indicators such as storage time and validity period to achieve first-in-first-out management of conductive silver glue and improve inventory turnover efficiency. In addition, when the conductive silver glue is taken out for use, the inventory data can be automatically updated through the data processing module to ensure the real-time and accuracy of the data.

[0034] In one embodiment, the positioning and picking system 40 includes a positioning module 41 and an indication module 42; the positioning module 41 is used to calculate the location information of the target conductive silver paste based on the inventory information, and locate the target conductive silver paste based on the location information; the indication module 42 is used to indicate the location of the target conductive silver paste by visual identification or auditory signal.

[0035] Specifically, the positioning and picking system 40 includes a positioning module 41 and an indication module 42. The positioning module 41 and the indication module 42 are linked through a data management system to further improve the storage efficiency and accuracy of the conductive silver paste, which has a positive impact on the overall operational efficiency.

[0036] The work contents of the positioning and picking-up system 40 include: receiving picking-up instructions, retrieving inventory information, indicating the picking-up location, and confirming the picking-up and updating the inventory.

[0037] Among them, receiving the pickup instruction includes: when the conductive silver paste is needed, the user uses a user interface, such as a touch screen, a computer terminal or a mobile application APP, to input the pickup instruction, and clearly specify the core information such as the model and quantity of the conductive silver paste required by the instruction. Then the instruction is transmitted to the positioning and pickup system 40 to start the subsequent process.

[0038] Inventory information retrieval includes: real-time access to the database in the data management system 30 through the built-in positioning module of the positioning and picking system 40, performing detailed inventory status query and conductive silver glue location tracking. When faced with multiple models or multiple batches of options, the system automatically selects the best batch based on preset priority rules, such as based on the storage market, to ensure scientific and efficient inventory management.

[0039] The pickup location indication includes: after the indication module 42 receives the positioning result, it quickly generates an intuitive location guide, and provides the operator with clear pickup location information through visual signs, such as LED guide lights, or auditory signals, such as buzzers, which greatly improves the convenience and accuracy of the pickup operation.

[0040] The picking confirmation and inventory update include: after the operator completes the picking task according to the instructions, the operator sends a picking completion signal to the system by scanning the RFID tag attached to the conductive silver glue or the operation confirmation button. The data management system 30 responds immediately and automatically performs the inventory data update operation, including reducing the quantity of the corresponding batch of conductive silver glue and recalculating the remaining total inventory, validity period and other key indicators.

[0041] In one embodiment, the warning system 50 includes an environmental anomaly alarm module 51 and an expiration date warning module 52; the environmental anomaly alarm module 51 is used to trigger an alarm mechanism when the temperature or humidity deviates from a preset range; the expiration date warning module 52 is used to send a warning message to the user when the critical point of the expiration date of the conductive silver paste meets the preset time.

[0042] Specifically, the early warning module 50 is tightly integrated with the data management system 30, and includes an abnormal environment alarm module 51 and an effective period early warning module 52. By integrating detailed environmental monitoring data with specific property information of conductive silver paste, accurate early warning of abnormal storage environment status is achieved.

[0043] Among them, the environmental abnormality alarm module 51 presets strict environmental parameter threshold standards, covering key indicators such as the upper and lower limits of temperature and humidity. The threshold is set according to the specific storage conditions and industry specifications of the conductive silver glue. The system continuously extracts real-time environmental data from the data management system 30 and automatically compares and analyzes it with the preset threshold. When it is detected that the environmental parameters deviate from the preset range, the system will immediately trigger the alarm mechanism, using on-site alarm methods including flashing LED indicators and buzzer alarms, and simultaneously sending alarm notifications to preset users through remote communication means such as text messages and emails to ensure that abnormal conditions are quickly responded to and handled.

[0044] The validity period warning module 52 is used to perform regular (such as daily) database inspection tasks and compare and analyze the validity period of the conductive silver glue. By comparing with the current date, the system can identify the batch of conductive silver glue that is about to reach the critical point of validity period in advance, such as the preset 10-day advance period. Once the warning condition is triggered, the system will automatically generate warning information containing key elements such as batch number, remaining validity period, storage location, etc., and send it to the designated user through preset channels, such as the user interface in the user management system, mobile phone APP push, SMS, etc. The user can arrange the use plan of the conductive silver glue in advance according to the warning information to avoid resource expiration waste and performance degradation.

[0045] In one embodiment, the user management system 60 includes a permission management module 61 and a remote monitoring module 62; the permission management module is used to manage permission control policies and record operation logs; the remote monitoring module is used to perform remote monitoring and inventory management through multiple access methods.

[0047] Among them, the permission management module 61 can implement strict permission control and assign different operation permissions to different users to ensure that only authorized users can perform related operations. At the same time, the system comprehensively records user operation logs, including key information such as operation time and operation content, to provide detailed data support for subsequent security audits and behavior tracing.

[0048] The remote monitoring module 62 supports multiple access methods such as computer terminals and mobile phone APPs to meet the operating habits and scenario requirements of different users. Users can view the environmental data and conductive silver paste information in the inventory, and grasp the inventory status in real time, including environmental parameters such as temperature, humidity, etc., and detailed information of the conductive silver paste, such as batch, expiration date, etc., to achieve convenient and efficient inventory management.
