Abstract
Description
Technical Field
[0001] This utility model relates to the field of material cabinet technology, and in particular to an intelligent shelf suitable for managing chip trays. Background Technology
[0002] Material cabinets are common storage devices widely used in various industrial production, warehousing management, laboratories, factory workshops, and other places. Their main function is to classify and store materials, tools, parts, etc., to facilitate material management and retrieval. Existing material cabinets usually adopt an open structure design, that is, the material storage area has no doors or only simple partitions for quick access to items. Although this design facilitates the retrieval of items and reduces the complexity of operation, it also brings some potential problems in actual use.
[0003] First, open-structure material cabinets lack effective item management methods, making it easy for errors to occur during the storage and retrieval of materials. During use, employees may mistakenly store or retrieve items due to poor visibility, memory lapses, or negligence. For example, in storage scenarios with multiple types of materials or multi-layered shelves, employees may store materials in inappropriate locations or mistakenly take one item for another. This not only leads to inefficient material flow but may also cause material loss or damage, affecting production progress and the efficiency of material management.
[0004] Secondly, existing open material cabinets lack intelligent item quantity monitoring systems, making it impossible to accurately determine changes in the number of trays inside the cabinet. Employees cannot understand the storage and retrieval status of materials in real time, which is particularly inconvenient for large-scale material management. In some scenarios that require accurate material tracking, relying on manual counting of material quantities not only increases the difficulty and workload of operations but also makes human error more likely. Especially when multiple employees share the same material cabinet, it is difficult to accurately record and control the inflow and outflow of materials, which greatly affects the accuracy and efficiency of inventory management.
[0005] In view of this, the inventor conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content
[0006] This utility model provides an intelligent shelf suitable for managing chip trays, aiming to solve the problems of mis-storage, mis-retrieval of materials, and inability to accurately monitor changes in material quantity in existing material cabinets.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0008] A smart shelf for managing chip trays includes a main cabinet and a secondary cabinet. The main cabinet has a hinged, openable door on one side and multiple storage spaces within it, each containing several tray placement components. The secondary cabinet includes a control unit and a recycling bin located below it, which can be controlled to open or close. Each tray placement component includes a support frame, with a drive unit at one end. The output end of the drive unit is connected to a movable rod, which has a through-hole placement slot along its length in the middle. A limit member is hinged to the end of the movable rod, and the free end of the limit member is hinged to the support frame. A detection unit is located above the drive unit and is electrically connected to the control unit for sensing the placement status of the trays in the placement slot.
[0009] Furthermore, the aforementioned support frame includes a horizontally arranged parallel section and an upwardly bent section. Vertical plates are provided on both sides of the bent section, and an electric lock is provided between the two vertical plates. The electric lock is the aforementioned drive unit.
[0010] Furthermore, a connecting block is provided at the bottom of the aforementioned movable rod, and the locking rod of the aforementioned electric lock is fixedly connected to the aforementioned connecting block; vertically arranged stop plates are protruding on both sides of the rear end of the aforementioned movable rod, and a first limiting rod for limiting the aforementioned connecting block and a second limiting rod for limiting the aforementioned stop plates are provided between the two aforementioned upright plates.
[0011] Furthermore, the aforementioned detection unit includes a fixed plate fixed between the two upright plates, a micro switch disposed on the fixed plate, and a movable plate hinged between the two upright plates. One side of the movable plate faces the limiting member, and the other side abuts against the detection end of the micro switch. When the tray is placed in the placement slot, its gravity presses down on the movable plate, causing the movable plate to trigger the micro switch and generate a storage signal. When the tray is removed from the placement slot, the movable plate resets, the micro switch opens, and a retrieval signal is generated. The micro switch is electrically connected to the control unit and is used to send the storage signal or retrieval signal to the control unit.
[0012] Furthermore, the top of the main cabinet is provided with a nitrogen inlet for external nitrogen to enter.
[0013] Furthermore, symmetrical limit rods for lateral limiting of the material tray are provided on both sides of the top surface of the aforementioned movable rod.
[0014] Furthermore, the aforementioned control unit is an embedded controller, and the outer side of the aforementioned sub-cabinet is also equipped with a touch screen and a scanning camera that are electrically connected to the controller.
[0015] Furthermore, the top of the aforementioned secondary cabinet is equipped with a monitoring camera and an alarm light that are electrically connected to the aforementioned control unit.
[0016] Furthermore, the lower part of the aforementioned sub-cabinet is recessed with a recycling chamber, and slide rails are provided on both sides of the bottom of the recycling chamber. The outer side of the aforementioned recycling box is provided with a delivery port, and the bottom is provided with a slider for cooperating with the aforementioned slide rails. The aforementioned recycling chamber is also provided with a linear drive unit for driving the aforementioned recycling box to move along the slide rails.
[0017] Furthermore, the linear drive unit is electrically connected to the control unit. When the material tray recycling operation is confirmed to be performed via the scanning camera or touch screen, the control unit controls the linear drive unit to drive the recycling box to move outside the recycling chamber.
[0018] As can be seen from the above description of the structure of this utility model, this utility model has the following advantages:
[0019] This utility model's shelving unit includes a main cabinet and a secondary cabinet. The main cabinet is equipped with several tray placement components, and the secondary cabinet includes a control unit and a recycling bin located below it, which can be opened or closed under control. Each tray placement component includes a support frame, with a drive unit at one end. The output end of the drive unit is connected to a movable rod, which has a placement slot for placing trays. A limiter is hinged to the end of the movable rod, and the free end of the limiter is hinged to the support frame. Above the drive unit is a detection unit for sensing the placement status of trays in the placement slot. This allows for precise sensing of the tray's placement status during material storage and retrieval, avoiding the problems of accidental storage or retrieval due to human error found in traditional material cabinets. This not only improves the accuracy of material management but also significantly reduces errors that may arise from manual operation. Furthermore, the recycling chamber and movable recycling bin design at the bottom of the secondary cabinet simplify the tray recycling process and improve work efficiency. Attached Figure Description

Detailed Implementation
[0033] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0034] Reference Figures 1 to 3A smart shelving system for managing chip trays includes a main cabinet 10 and a secondary cabinet 20. One or both sides of the main cabinet 10 have hinged, closable doors 11. The gap between the door 11 and the main cabinet 10 is filled with sealant. The main cabinet 10 contains multiple storage spaces 12, which can be divided by multiple shelves. Each storage space 12 contains several tray placement components. The top of the main cabinet 10 has a nitrogen inlet 13 for external nitrogen gas entry. The secondary cabinet 20 includes a control unit 21 and a control unit located below it that can be controlled by... The recycling bin 22 is controlled to open or close; the tray placement assembly includes a support frame 31, one end of which is provided with a drive unit 32, the output end of which is connected to a movable rod 33, the middle of which has a through placement groove 331 along its length, and the end of which is hinged to a limit member 34, the free end of which is hinged to the support frame 31; a detection unit 40 is provided above the drive unit 32, which is electrically connected to the control unit 21 and is used to sense the placement status of the tray in the placement groove 331.
[0035] In application, when the tray is placed in the placement slot 331 of the movable rod 33, the detection unit 40 is triggered, generating a storage signal and transmitting it to the control unit 21, thereby achieving accurate recording of the material. Simultaneously, the design of the limiting rod 335 and the limiting element 34 ensures the stability of the tray within the placement slot 331, preventing displacement or falling due to external vibration or misoperation. Furthermore, the nitrogen inlet 13 at the top of the main cabinet 10 provides a protective gas environment for specific materials, preventing moisture or oxidation, further enhancing storage safety and reliability. The recycling bin 22 in the auxiliary cabinet 20 facilitates the handling of waste materials or empty trays, improving tray recycling efficiency.
[0036] Reference Figures 1 to 9The support frame 31 includes a horizontally arranged parallel section 311 and an upwardly bent section 312. Vertically arranged upright plates 50 are provided on both sides of the bent section 312, and a connecting column 51 is provided between the two upright plates 50. An electric lock, the aforementioned drive unit 32, is mounted on the connecting column 51. A connecting block 332 is provided at the bottom of the movable rod 33, and the locking rod of the electric lock is fixedly connected to the connecting block 332. Vertically arranged stop plates 333 protrude from both sides of the rear end of the movable rod 33. A first limiting rod 52 for limiting the connecting block 332 and a second limiting rod 53 for limiting the stop plate 333 are provided between the movable rod 33 and the support frame 31. Symmetrical limiting rods 335 for lateral limiting of the material tray are provided on both sides of the top surface of the movable rod 33. In application, the motor inside the electric lock drives the locking rod to extend or retract, thereby moving the connecting block 332 and the movable rod 33 connected to it, and thus allowing the limiting member 34 to move accordingly, thereby realizing the automatic locking or releasing operation of the material tray. When the material tray needs to be fixed, the electric lock drives the movable rod 33 to move until the limiting member 34 and the support frame 31 form a closed state, ensuring the material tray is placed stably. When the material tray needs to be removed, the electric lock reverses its action, driving the movable rod 33 to move, causing the limiting member 34 to open, facilitating the quick removal of the material tray. This not only improves the convenience of operation but also effectively avoids the problem of misplacement or loss of materials due to human negligence.
[0037] Reference Figures 1 to 9 The detection unit 40 includes a fixed piece 41 fixed between two upright plates 50, a micro switch 42 disposed on the fixed piece 41, and a movable piece 43 hinged between the two upright plates 50. One side of the movable piece 43 faces the limiting member 34, and the other side abuts against the detection end of the micro switch 42. When the tray is placed in the placement slot 331, its gravity presses against the movable piece 43, causing the movable piece 43 to trigger the micro switch 42 and generate a storage signal. When the tray is removed from the placement slot 331, the movable piece 43 resets, the micro switch 42 opens, and a retrieval signal is generated. The micro switch 42 is electrically connected to the control unit 21 and can send the storage signal or retrieval signal to the control unit 21. In application, the detection unit 40, through the cooperation of the movable piece 43 and the micro switch 42, can accurately sense the presence or absence of the tray and transmit the signal to the control unit 21 in real time, thereby ensuring that every storage and retrieval operation is accurately recorded, providing reliable data support for subsequent material management.
[0038] Reference Figures 1 to 9The control unit 21 is an embedded controller, which is a conventional technology and will not be described in detail here. The outer side of the secondary cabinet 20 is equipped with a touch screen 23 and a scanning camera 24 electrically connected to the control unit 21. The top of the secondary cabinet 20 is equipped with a monitoring camera 25 and an alarm light 26 electrically connected to the control unit 21. In application, the control unit 21 can receive signals from the detection unit 40, the touch screen 23, and the scanning camera 24, and complete corresponding operations according to preset logic. For example, when an employee enters the material tray information through the scanning camera 24, the control unit 21 will automatically identify the location of the target material tray and drive the corresponding electric lock to move the movable lever 33 to the appropriate position for storage and retrieval. Simultaneously, the monitoring camera 25 records the operating status of the material cabinet in real time. Once abnormal behavior or unauthorized operation is detected, the alarm light 26 will immediately activate to remind management personnel to handle the situation promptly. In addition, the monitoring camera 25 on the top of the secondary cabinet 20 can record the dynamic situation around the material cabinet around the clock, while the alarm light 26 will issue a warning when abnormal operation or unauthorized access is detected. This dual security measure not only improves the protection level of the equipment, but also provides users with a more reassuring user experience.
[0039] Reference Figures 1 to 10 The lower part of the auxiliary cabinet 20 is recessed with a recycling chamber 201. The bottom of the recycling chamber 201 is provided with slide rails 202 on both sides. The outer side of the recycling box 22 is provided with a delivery port 221. The bottom is provided with a slider 222 for cooperating with the slide rails 202. The recycling chamber 201 is also provided with a linear drive unit 203 for driving the recycling box 22 to move along the slide rails 202. The linear drive unit 203 is electrically connected to the control unit 21. In this embodiment, the linear drive unit 203 is a cylinder. When the operator confirms the execution of the material tray recycling operation through the scanning camera 24 or the touch screen 23, the control unit 21 controls the linear drive unit 203 to drive the recycling box 22 to move out of the recycling chamber 201. By designing the recycling bin 22 to automatically push out and retract, the processing flow of the recycling tray is simplified, and the safety hazards that may be caused by manual operation are avoided. At the same time, the cooperation between the slide rail 202 and the linear drive unit 203 ensures the smooth movement of the recycling bin 22, while the setting of the delivery port 221 provides users with more convenient operation, significantly improving work efficiency and reducing management costs.
[0040] Reference Figures 1 to 11In this invention, when storing materials, the operator first needs to open the cabinet door 11 of the main cabinet 10 and select the "Store Material" function on the touch screen 23. Next, the system verifies permissions. If the verification is successful, the operator proceeds to the next step; if the verification fails, the alarm light 26 is triggered, prompting the operator to repeat the operation. Then, the operator scans the material tray's input barcode. If the barcode information is missing or does not meet the requirements, the alarm light 26 illuminates, indicating that a valid material number has not been identified. Subsequently, the operator selects the storage slot on the touch screen 23 and clicks the "Confirm" button. The electric lock moves the movable rod 33, adjusting the tray placement component to the "Retrieve Material" state. The operator places the tray into the corresponding slot's tray placement component. The electric lock then activates again, and the movable rod 33 moves the component back to the "Store Material" state, ensuring the tray is securely stored. After storage is complete, the detection unit 40 recognizes that the tray has been correctly stored and transmits the signal to the control unit 21. The control unit 21 automatically updates the system database and stores the relevant data. Finally, the operator closes the cabinet door 11 of the main cabinet 10, completing the storage operation.
[0041] Reference Figures 1 to 12 When retrieving materials, the staff first opens the cabinet door 11 of the main cabinet 10 and selects the "Retrieve Material" function on the touch screen 23 interface. The system performs permission verification. If the verification is successful, the next step is performed. If the verification fails, the alarm light 26 lights up, prompting the staff to operate again. The staff scans the material barcode. If the barcode is invalid or missing, the alarm light 26 is triggered, indicating that no valid material number has been identified. Next, the staff scans the empty material tray barcode. After the system verifies, it prompts the staff to put the empty material tray into the recycling bin 22. If the empty tray is not scanned, the alarm light 26 sounds, indicating an operation error. After clicking the "Confirm" button, the system switches to the "Retrieve Material State". The staff can then remove the material tray placed on the material tray placement component. When the staff removes the material tray from the material tray placement component, the detection unit 40 detects that the material tray has been removed and sends a signal to the control unit 21. The control unit 21 controls the drive unit 32 to move the movable rod 33, so that the material tray placement component returns to the "Storage Material State". Subsequently, the control unit 21 updates the data, records and stores the material retrieval information, and finally, the operator closes the cabinet door 11 of the main cabinet 10, completing the material retrieval operation. The entire system automatically adjusts the placement of the material tray through the drive unit 32 and the movable lever 33, reducing human error and ensuring that every step is effectively monitored. Furthermore, through the linkage between the detection unit 40 and the control unit 21, inventory information is updated in real time, ensuring accurate and timely data and improving work efficiency and safety.
[0042] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
