Description

Technical Field

[0001] This utility model relates to the field of logistics warehousing and inventory management, and in particular to a turnover box inventory management device that integrates weighing and RFID. Background Technology

[0002] In modern logistics, warehousing, and production line management, turnover boxes are commonly used containers for carrying materials. To achieve refined management, it is usually necessary to identify and count the items inside the turnover boxes. Currently, common practices include:

[0003] RFID technology: RFID tags are affixed to turnover boxes, and readers can identify them in batches over a long distance to achieve rapid inventory and tracking of items. However, it cannot know the real-time weight or quantity changes of the items inside the boxes.

[0004] Weighing technology: Weighing the turnover boxes using weighbridges or platform scales, and estimating the quantity of items by calculating the difference between the gross weight and the tare weight. However, this method requires manual recording, cannot automatically associate the turnover box's identity information, is inefficient, and is prone to errors.

[0005] Simply combining two technologies, such as using separate RFID readers and scales, results in problems such as scattered equipment, cumbersome operation, asynchronous data, and large space occupation.

[0006] To address this, we propose a turnover box inventory management device that integrates weighing and RFID. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a turnover box inventory management device that integrates weighing and RFID. By setting up management components, the weighing sensor, RFID reader, control processing module and other components are integrated into a management cabinet, avoiding the cumbersome use of separate equipment (such as scattered RFID readers and platform scales), reducing the space occupied by the equipment, lowering the overall hardware cost and installation complexity. The management cabinet has two receiving cavities, allowing multiple turnover boxes to be processed at the same time, improving space utilization and making it suitable for high-density warehousing environments.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] An integrated weighing and RFID inventory management device for turnover boxes includes a management cabinet with two receiving cavities inside, a management component inside the management cabinet, an auxiliary component inside the management cabinet, and a sealing component at the front end of the management cabinet.

[0010] The management component includes a weighing sensor, which is fixedly embedded in the bottom of the receiving cavity. An RFID reader is fixedly connected to the top of the receiving cavity. A control processing module is fixedly connected to the upper end of the receiving cavity. The control processing module includes a housing, a display screen is fixedly connected to the upper end of the housing, a microcontroller unit is fixedly connected inside the housing, a communication module is fixedly connected inside the housing, an analog-to-digital converter is fixedly connected inside the housing, and a network interface is fixedly connected to the left end of the housing. The control processing module is electrically connected to both the weighing sensor and the RFID reader.

[0011] By setting up a management component, weighing sensors, RFID readers, control processing modules, etc. are integrated into a management cabinet, avoiding the cumbersome use of separate devices (such as scattered RFID readers and platform scales), reducing the space occupied by the equipment, lowering the overall hardware cost and installation complexity. The management cabinet has two receiving cavities inside, allowing multiple turnover boxes to be processed at the same time, improving space utilization and making it suitable for high-density warehousing environments.

[0012] The control and processing module is directly connected to the weighing sensor and RFID reader, which can automatically associate the RFID identification information of the turnover box with the real-time weight data to achieve a one-to-one binding of "identity-weight". This eliminates the errors and data asynchrony problems caused by manual recording. The gross weight is obtained by the weighing sensor and combined with the preset tare weight (the weight of the turnover box itself) to automatically calculate the net weight or the quantity of items, so as to achieve accurate inventory statistics without manual intervention. The RFID reader identifies the turnover box when it enters the receiving cavity, and the weighing sensor automatically weighs it at the same time. The whole process is completed within seconds, which greatly improves the efficiency of inventory, warehousing and outbound operations.

[0013] Furthermore, the auxiliary component includes a groove, which is formed below the front end of the management cabinet and is symmetrically distributed from left to right.

[0014] Furthermore, a pair of guide rods are fixedly connected inside the groove, a limiting piece is fixedly connected to the front end of the guide rods, and a guide sleeve is slidably connected to the outside of the guide rods.

[0015] Furthermore, a mounting bracket is fixedly connected to the front end of the guide sleeve, and an auxiliary guide plate is hinged to the front end of the mounting bracket. Both the mounting bracket and the auxiliary guide plate are movably arranged with the groove.

[0016] Furthermore, the sealing assembly includes a sealing door, which is hinged to the front end of the management cabinet, and a connecting seat is fixedly connected to the front end of the management cabinet.

[0017] Furthermore, an electromagnetic lock is fixedly fitted at one end of the connecting seat near the sealing door, and a lock hole is provided at one end of the sealing door near the connecting seat.

[0018] Furthermore, the keyhole is adapted to the bolt of the electromagnetic lock, and the keyhole is movably inserted into the bolt of the electromagnetic lock.

[0019] Furthermore, a control switch is fixedly connected to the front end of the connector, and the control switch is electrically connected to the electromagnetic lock.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. By setting up management components, weighing sensors, RFID readers, control processing modules, etc. are integrated into a management cabinet, avoiding the cumbersome use of separate devices (such as scattered RFID readers and platform scales), reducing the space occupied by the equipment, lowering the overall hardware cost and installation complexity. The management cabinet has two receiving cavities inside, allowing multiple turnover boxes to be processed at the same time, improving space utilization and making it suitable for high-density warehousing environments.

[0022] 2. The control and processing module is directly connected to the weighing sensor and RFID reader, which can automatically associate the RFID identification information of the turnover box with the real-time weight data to achieve a one-to-one binding of "identity-weight". This eliminates the errors and data asynchronization problems caused by manual recording. The gross weight is obtained by the weighing sensor and combined with the preset tare weight (the weight of the turnover box itself) to automatically calculate the net weight or the quantity of items, so as to achieve accurate inventory statistics without manual intervention. The RFID reader identifies the turnover box when it enters the receiving cavity, and the weighing sensor automatically weighs it at the same time.

[0033] Reference Figures 1-7 As shown, a preferred embodiment of the present invention is a turnover box inventory management device integrating weighing and RFID, including a management cabinet 1, two receiving cavities 2 inside the management cabinet 1, a management component 3 inside the management cabinet 1, an auxiliary component 4 inside the management cabinet 1, and a sealing component 5 at the front end of the management cabinet 1.

[0034] The management component 3 includes a weighing sensor 301, which is fixedly fitted into the bottom of the receiving cavity 2. An RFID reader 302 is fixedly connected to the top of the receiving cavity 2. A control processing module 303 is fixedly connected to the upper end of the receiving cavity 2. The control processing module 303 includes a housing 3031, a display screen 3032 fixedly connected to the upper end of the housing 3031, a microcontroller unit 3033 fixedly connected inside the housing 3031, a communication module 3034 fixedly connected inside the housing 3031, an analog-to-digital converter 3035 fixedly connected inside the housing 3031, and a network interface 3036 fixedly connected to the left end of the housing 3031. The control processing module 303 is electrically connected to the weighing sensor 301 and the RFID reader 302.

[0035] By setting up management component 3, weighing sensor 301, RFID reader 302, control processing module 303 and other components are integrated into one management cabinet 1, avoiding the cumbersome use of separate devices (such as scattered RFID reader 302 and platform scale), reducing the space occupied by the equipment, lowering the overall hardware cost and installation complexity. The management cabinet 1 has two receiving cavities 2 inside, which allows multiple turnover boxes to be processed at the same time, improving space utilization and making it suitable for high-density warehousing environments.

[0036] The control processing module 303 is directly connected to the weighing sensor 301 and the RFID reader 302. It can automatically associate the RFID identity information of the turnover box with the real-time weight data to achieve a one-to-one binding of "identity-weight". This eliminates the errors and data asynchrony problems caused by manual recording. The gross weight is obtained by the weighing sensor 301 and combined with the preset tare weight (the weight of the turnover box itself) to automatically calculate the net weight or the quantity of items, so as to achieve accurate statistics of inventory quantity without manual intervention. The RFID reader 302 identifies the identity when the turnover box enters the receiving cavity 2, and the weighing sensor 301 automatically weighs it at the same time. The whole process is completed within seconds, which greatly improves the efficiency of inventory, warehousing and outbound operations.

[0037] The communication module 3034 and network interface 3036 support data uploading to enterprise ERP, WMS or other management systems, enabling real-time monitoring and remote management of inventory data, which helps to achieve supply chain visualization, decision support and big data analysis.

[0038] Reference Figures 1-7 As shown, the auxiliary component 4 includes a groove 401, which is located below the front end of the management cabinet 1 and is symmetrically distributed from left to right.

[0039] Reference Figures 1-7 As shown, a pair of guide rods 402 are fixedly connected inside the groove 401. A limit piece 403 is fixedly connected to the front end of the guide rod 402, and a guide sleeve 404 is slidably connected to the outside of the guide rod 402.

[0040] Reference Figures 1-7 As shown, the front end of the guide sleeve 404 is fixedly connected to the mounting bracket 405, and the front end of the mounting bracket 405 is hinged to the auxiliary guide plate 406. Both the mounting bracket 405 and the auxiliary guide plate 406 are movably arranged with the groove 401.

[0041] By setting the auxiliary component 4, when the turnover box is placed in the receiving cavity 2, the sealing door 501 is opened and the auxiliary guide plate 406 is pulled out from the groove 401 to the outermost position. At this time, since the bottom of the guide plate is hinged to the mounting bracket 405, the guide plate can tilt downward, so that the receiving cavity 2 forms a slope with the ground, which helps the turnover box to enter the receiving cavity 2 smoothly, reduces the adjustment time of the operator, and reduces the labor intensity.

[0042] Reference Figures 1-7 As shown, the sealing assembly 5 includes a sealing door 501, which is hinged to the front end of the management cabinet 1. A connecting seat 502 is fixedly connected to the front end of the management cabinet 1.

[0043] Reference Figures 1-7 As shown, an electromagnetic lock 503 is fixedly fitted at one end of the connecting seat 502 near the sealing door 501, and a lock hole 504 is opened at one end of the sealing door 501 near the connecting seat 502.

[0044] Reference Figures 1-7 As shown, the keyhole 504 is adapted to the latch of the electromagnetic lock 503, and the keyhole 504 and the latch of the electromagnetic lock 503 are movably connected.

[0045] Reference Figures 1-7 As shown, a control switch 505 is fixedly connected to the front end of the connector 502, and the control switch 505 is electrically connected to the electromagnetic lock 503.

[0046] By setting the sealing component 5, when the electromagnetic lock 503 is de-energized, the lock tongue is inserted into the lock hole 504. The control switch 505 is used to energize the electromagnetic lock 503, and the lock tongue retracts into the electromagnetic lock 503 body, separating from the lock hole 504, so that the sealed door 501 can be opened.

[0047] Specific implementation process: When the electromagnetic lock 503 is de-energized, the bolt is inserted into the lock hole 504. The control switch 505 is used to energize the electromagnetic lock 503, and the bolt retracts into the body of the electromagnetic lock 503 and separates from the lock hole 504, so that the sealed door 501 can be opened.

[0048] When placing the turnover box in the receiving cavity 2, open the sealing door 501 and pull the auxiliary guide plate 406 out of the groove 401 to the outermost position. At this time, since the bottom of the guide plate is hinged to the mounting bracket 405, the guide plate can tilt downwards, so that the receiving cavity 2 forms a slope with the ground, which helps the turnover box to enter the receiving cavity 2 smoothly, reduces the adjustment time of the operator, and reduces the labor intensity.

[0049] The weighing sensor 301, RFID reader 302, control processing module 303 and other components are integrated into a management cabinet 1, which avoids the cumbersome use of separate devices (such as separate RFID readers 302 and platform scales), reduces the space occupied by the equipment, and lowers the overall hardware cost and installation complexity. The management cabinet 1 has two receiving cavities 2 inside, which allows multiple turnover boxes to be processed at the same time, improves the space utilization rate, and is suitable for high-density warehousing environments.

[0050] The control processing module 303 is directly connected to the weighing sensor 301 and the RFID reader 302. It can automatically associate the RFID identification information of the turnover box with the real-time weight data to achieve a one-to-one binding of "identity-weight". This eliminates the errors and data asynchrony problems caused by manual recording. The gross weight is obtained by the weighing sensor 301 and combined with the preset tare weight (the weight of the turnover box itself) to automatically calculate the net weight or the quantity of items, so as to achieve accurate inventory statistics without manual intervention. The RFID reader 302 identifies the identity when the turnover box enters the receiving cavity 2, and the weighing sensor 301 automatically weighs it at the same time. The whole process is completed within seconds, which greatly improves the efficiency of inventory, warehousing and outbound operations. The data information is displayed on the display screen 3032.
