Description

Technical Field

[0001] This application relates to the field of toolbox technology, and in particular to an RFID-controlled smart toolbox and its usage method. Background Technology

[0002] Radio Frequency Identification (RFID) technology, as a type of automatic identification technology, enables contactless two-way data communication via wireless radio frequency. It allows for the reading and writing of electronic tags, achieving target identification and data exchange. Currently, this technology has been applied in the field of tool management, enabling rapid identification and basic management of tool information by setting electronic tags on tools.

[0003] However, existing tool management solutions still have significant shortcomings. While some tool cabinets using RFID technology have improved tool identification and retrieval records, users still need to manually open the cabinet doors or drawers and search for the required tools inside. This operating mode has the following drawbacks: First, tool retrieval efficiency is low, as users spend time and effort searching for specific tools among a cluttered array; second, manually searching for sharp tools poses safety hazards; and third, existing solutions lack the ability to monitor the physical condition of the tools themselves, failing to promptly detect wear, damage, or surface contamination.

[0004] Therefore, there is an urgent need for an intelligent toolbox that can automate the picking and placing of tools and monitor their physical status in real time, in order to solve the problems of low efficiency, safety hazards and lack of status monitoring in existing technologies. Summary of the Invention

[0005] To address the problems of low efficiency, safety hazards, and inability to monitor the physical status of tools in real time caused by manual handling in existing technologies, this application provides an RFID-controlled intelligent toolbox and its usage method.

[0006] The present application provides an RFID-based intelligent toolbox and its usage method, which adopts the following technical solution: An RFID-based intelligent toolbox includes: Box; A drawer, located inside the box, is used to store tools with electronic tags attached; The control module is located on the housing; A tool transfer channel is provided between the box and the drawer; A position adjustment mechanism is located inside the drawer and is signal-connected to the control module; A weighing sensor is mounted on the position adjustment mechanism and is signal-connected to the control module. The control module is configured to: identify the target tool by reading the electronic tag; control the position adjustment mechanism to move the target tool to the tool transfer channel to complete automatic pick-up and drop-off; and determine the physical state of the tool based on the weight information obtained by the weighing sensor.

[0007] By adopting the above technical solution, and through the coordinated operation of the control module, position adjustment mechanism, tool transfer channel and weighing sensor, the automated picking and placing and status monitoring of tools can be achieved. This solution can not only automatically complete the precise positioning and transfer of tools, avoiding the inefficiency and safety hazards caused by manual searching, but also monitor the wear, damage or contamination of tools in real time through weight changes, thus upgrading from tool management to tool health status management.

[0008] In one specific implementation, the tool transfer channel includes a first inlet / outlet on the housing and a second inlet / outlet on the drawer; when the drawer is closed in the housing, the first inlet / outlet corresponds to and is connected to the second inlet / outlet; the first inlet / outlet is provided with an electric door, and the housing is provided with a first telescopic member that drives the electric door.

[0009] By adopting the above technical solution and utilizing the corresponding settings of the first and second inlets and outlets, a complete tool transfer path is formed when the drawer is closed. Combined with the automatic opening and closing of the electric door, the sealing of the toolbox is ensured, and the automatic transfer of tools is realized, greatly improving the convenience of use.

[0010] In one specific implementation, the position adjustment mechanism includes a conveying unit, a lifting unit, a pushing unit, and a displacement driving unit; the conveying unit is used to convey the tool inside the drawer, the lifting unit is used to receive the tool at the end of the conveying unit and move it up and down, the pushing unit is used to push the tool located on the lifting unit into or out of the tool transfer channel, and the displacement driving unit is used to drive the conveying unit to move as a whole so that it docks with or separates from the lifting unit.

[0011] By adopting the above technical solution and utilizing the coordinated operation of four functional units, a multi-degree-of-freedom tool positioning and transfer system is constructed. The conveying unit is responsible for the horizontal tool transport, the lifting unit realizes the vertical positioning, the pushing unit completes the final pick-up and place operation, and the displacement driving unit ensures the precise docking between the units, forming a complete automated tool pick-up and place solution.

[0012] In one specific implementation, the transmission unit includes: Two sets of bearing seats are located inside the drawer and are slidably connected to the drawer. The driving shaft and the driven shaft are rotatably connected between the two sets of bearing housings; A conveyor belt is tensioned on the drive shaft and the driven shaft; The motor is mounted on the bearing housing, and its output end is fixedly connected to the drive shaft. Several adsorption elements are disposed on the conveyor belt for adsorbing and fixing the tool.

[0013] By adopting the above technical solution, the conveyor belt mechanism, in conjunction with the suction device, enables stable transfer of tools inside the drawer. The sliding connection design of the bearing seat allows the entire conveyor unit to move flexibly, the motor drive ensures the controllability of the conveying speed, and the suction device ensures that the tools will not shift or fall off during the transfer process, providing a reliable mechanical foundation for picking up and putting down tools.

[0014] In one specific implementation, the lifting unit includes a lifting plate and a fifth telescopic member for driving its vertical lifting, and the weighing sensor is disposed on the lifting plate; the lifting plate is configured such that when it is lowered to its lowest position, its top surface is flush with the bottom edge of the tool transfer channel.

[0015] By adopting the above technical solution and utilizing the positioning function of the lifting plate, a stable measurement platform is provided for the weighing sensor, and the smooth transition of the tool during the transfer process is ensured. When the lifting plate descends to the lowest position and is flush with the bottom edge of the transfer channel, the tool can be smoothly transferred inside and outside the drawer, realizing a seamless connection between weight detection and automatic pick-up and drop-off.

[0016] In one specific implementation, the pushing unit includes a push plate and a fourth telescopic member that drives its horizontal movement; the push plate is configured to reciprocate on the lifting plate to push the tool out of the housing or into the drawer via the tool transfer channel.

[0017] By adopting the above technical solution, the final picking and placing operation of the tool is realized by using the horizontal reciprocating motion of the push plate. The movement trajectory of the push plate on the lifting plate is precisely designed to ensure that the tool passes through the transfer channel accurately and smoothly, completing the complete transfer process from inside the box to outside the box, and realizing automated picking and placing.

[0018] In one specific implementation, the displacement driving unit includes a third telescopic member disposed inside the drawer, the output end of the third telescopic member being connected to the bearing seat for driving the entire transmission unit to move.

[0019] By adopting the above technical solution, the position of the conveying unit can be flexibly adjusted using the displacement drive unit, so that the conveying unit can switch between the working position and the standby position as needed, which avoids interference with other components and provides greater flexibility for the storage and retrieval of tools of different sizes.

[0020] In one specific implementation, a cleaning brush is also provided above the conveyor belt, and the cleaning brush is connected to the drive shaft through a transmission mechanism.

[0021] By adopting the above technical solution, a cleaning brush that runs synchronously with the conveyor belt automatically cleans the surface of the tool during the conveying process. This design can not only remove dust and debris from the tool surface and keep the tool clean, but also avoid impurities from interfering with subsequent weight detection and improve the accuracy of condition judgment.

[0022] In one specific implementation, the cabinet body is provided with a locking mechanism for each drawer. The locking mechanism includes a second telescopic member and a locking rod on the cabinet body, and a locking hook on the drawer. The second telescopic member is used to drive the locking rod to disengage from or engage with the locking hook.

[0023] By adopting the above technical solution, the drawer can be automatically locked using a locking mechanism. When tools need to be stored or retrieved, the second telescopic component drives the locking rod to disengage from the locking hook. After the operation is completed, the locking rod automatically engages with the locking hook, ensuring that the drawer remains locked when not in use, thus improving the security of tool storage.

[0024] In one specific implementation, the interior of the cabinet is provided with a pop-out auxiliary component for each drawer; the pop-out auxiliary component includes a storage slot, a first spring disposed in the storage slot, and a stop plate, the two ends of the first spring being connected to the cabinet and the stop plate respectively, and the stop plate abutting against the drawer; when the second telescopic member drives the locking rod to disengage from the locking hook, the stop plate pushes the drawer outward under the action of the first spring.

[0025] By adopting the above technical solution, the drawer can automatically pop out by utilizing the elastic force of the first spring in conjunction with the stop plate. When the locking mechanism is unlocked, the accumulated spring potential energy is converted into kinetic energy through the stop plate, pushing the drawer out a certain distance, which facilitates further operation by the user and improves user experience and ease of operation.

[0026] In one specific implementation, the control module includes a reader for reading the electronic tag information and a processor that is signal-connected to the weighing sensor and the reader; the processor is also signal-connected to a warning light for providing status indication to the outside world.

[0027] By adopting the above technical solution, the reader is responsible for identifying the tool's identity information, the processor performs logical judgments and system control, and the warning light provides intuitive status feedback, forming a complete control closed loop of perception, decision-making, and execution.

[0028] In one specific implementation scheme, it also includes an environmental control system, which includes an air pipe installed on the housing, an air pump connected to the air pipe, and at least one of a temperature control device, a dehumidification device, and a filtration device connected in series on the air pump pipeline.

[0029] By adopting the above technical solution, an environmental control system is used to provide the best storage environment for tools. By driving airflow circulation through an air pump, and in conjunction with temperature control, dehumidification and filtration equipment, the temperature and humidity inside the toolbox can be regulated and the air can be purified, effectively preventing tool corrosion and contamination and extending the tool's service life.

[0030] A method for using an RFID-controlled smart toolbox as described above includes the following steps: Affix an electronic tag to the tool and place it on the position adjustment mechanism; register the tool information and its standard weight in the control module. When a tool is lent out, the control module controls the position adjustment mechanism to move the target tool to the tool transfer channel; the weight of the lent tool is obtained by the weighing sensor and recorded by the control module. When a tool is returned, the control module identifies the electronic tag of the tool and controls the opening of the corresponding tool transfer channel; after the user puts the tool in, the weight of the returned tool is obtained by the weighing sensor and recorded by the control module. The control module compares the returned weight with the borrowed weight or the standard weight, and determines whether the physical state of the tool is abnormal based on the weight change.

[0031] By adopting the above technical solution and utilizing a complete tool lifecycle management process, the entire process from tool registration, borrowing management, return detection to status assessment can be automated. Through precise analysis of weight changes, this method can promptly detect abnormal tool conditions, providing a scientific basis for tool maintenance and management.

[0032] In a specific implementation scheme, the step of determining whether the physical state of the tool is abnormal based on the weight change specifically includes: calculating the difference between the returned weight and the borrowed weight through the control module; if the absolute value of the difference is greater than the preset allowable weight deviation for a single use of the tool, then the tool is determined to be in an abnormal state. If the returned weight is greater than the borrowed weight, it is determined that the tool is covered with debris; if the returned weight is less than the borrowed weight, it is determined that the tool is worn or damaged.

[0033] By adopting the above technical solution, intelligent diagnosis of tool status can be achieved through weight difference analysis. By setting a reasonable weight deviation threshold, the normal use and abnormal status of the tool can be accurately distinguished, and the specific abnormality type can be determined according to the direction of weight change, automatically triggering corresponding handling measures to realize intelligent tool maintenance.

[0034] In summary, the beneficial technical effects of this application are as follows: Through the coordinated operation of the control module, position adjustment mechanism, tool transfer channel, and weighing sensor, automated tool handling and intelligent status monitoring are achieved, constructing a complete tool lifecycle management system. This solution not only automatically completes tool positioning and rapid transfer, effectively avoiding the inefficiency and safety hazards caused by manual searching, but also monitors tool wear, damage, or contamination in real time through weight change analysis, achieving a technological upgrade from traditional tool management to tool health status management. Simultaneously, the system's integrated automatic cleaning, environmental control, and intelligent alarm functions further enhance the intelligence level of tool management, providing comprehensive technical support for tool maintenance and use, and significantly improving the efficiency and reliability of tool management.

[0043] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0044] Example 1 Reference Figure 1 and 2 This application discloses an RFID-controlled smart toolbox, including a box body 1, a plurality of drawers 6 disposed in the box body 1, a control module disposed on the box body 1, a tool transfer channel disposed between the box body 1 and the drawers 6, a position adjustment mechanism 9 disposed in the drawers 6, and a weighing sensor disposed on the position adjustment mechanism 9.

[0045] In this embodiment, the side of the box 1 where the reader 5 is located has several openings, each opening accommodating a drawer 6. Each drawer 6 constitutes an independent tool management unit. In this embodiment, the side of the drawer 6 parallel to the reader 5 has a pull-out opening 61, which allows the staff to manually pull out the drawer 6 when necessary. In this embodiment, the bottom of the box 1 is equipped with four directional wheels and a braking device, which allows the toolbox to move flexibly and be fixed in position when needed, adapting to the needs of different work sites.

[0046] The control module serves as the control center of the entire system, including a processor 3, a reader 5, and a touch screen 4 located on the top of the housing 1. The processor 3 is connected to the reader 5 and the touch screen 4 via signals. The processor 3 is responsible for the system's logical operations and issuing control commands. The reader 5 is used to read the identification information of the electronic tags on the tool. The touch screen 4 provides a human-machine interface for displaying tool information, system status, and receiving user operation commands.

[0047] The control module is configured to perform the following functions: identify the target tool by reading the electronic tag on the tool; control the position adjustment mechanism 9 to move the target tool to the tool transfer channel to complete automatic pick-up and drop-off; and determine the physical state of the tool based on the weight information obtained by the weighing sensor.

[0048] Reference Figure 1 and 2 In this embodiment, the housing 1 is also provided with several warning lights 7. The warning lights 7 are located on the side of the reader 5 on the housing 1, and the warning lights 7 are corresponding to each drawer 6. In this embodiment, the warning lights 7 support multiple display modes: a single flash at equal intervals indicates that the tool is weighing abnormally; a double flash at equal intervals indicates that the tool is lost; and a constant light indicates that the number of times the tool has been used has exceeded the limit.

[0049] Reference Figure 2 and 3 The tool transfer channel includes a first inlet / outlet 11 located on the side of the housing 1 and a second inlet / outlet 98 located on the side of the drawer 6; when the drawer 6 is completely closed inside the housing 1, the first inlet / outlet 11 and the second inlet / outlet 98 are aligned to form a complete tool transfer path.

[0050] An electric door 12 is provided at the first inlet / outlet 11. The electric door 12 is opened and closed by a first telescopic member 13 located inside the housing 1. The first telescopic member 13 is an electric push rod, and its output end is fixedly connected to the electric door 12. When the control module receives the opening command, the first telescopic member 13 drives the electric door 12 to slide smoothly along the guide rail, realizing the reliable opening of the tool transfer channel. After the operation is completed, the first telescopic member 13 moves in the opposite direction, pushing the electric door 12 to close the tool transfer channel and maintain the airtightness of the housing 1.

[0051] like Figures 3 to 5 As shown, the position adjustment mechanism 9 includes four main parts: a conveying unit, a lifting unit, a pushing unit, and a displacement driving unit. Each unit works together under the coordinated control of the control module to realize the picking and placing of tools.

[0052] The specific components of the transmission unit include: two sets of bearing seats 91, which are slidably connected to the bottom of the drawer 6 via slide rails; The drive shaft 93 and the driven shaft 94 are rotatably connected between two sets of bearing housings 91 via bearings; Conveyor belt 95 is tensioned on drive shaft 93 and driven shaft 94; The motor 92 is fixed on one of the bearing housings 91, and its output end is fixedly connected to the drive shaft 93 through a coupling. Several adsorption elements 96 are evenly distributed on the surface of the conveyor belt 95.

[0053] In this embodiment, the adsorption element 96 can be an electromagnet or a vacuum chuck; when an electromagnet is used, the adsorption is achieved by energizing and the release is achieved by de-energizing through a control circuit; when a vacuum chuck is used, the adsorption and release are achieved by a micro vacuum pump and a solenoid valve control system.

[0054] In this embodiment, a cleaning brush 97 is also provided above the conveying unit. The cleaning brush 97 is connected to the drive shaft 93 through a synchronous belt drive mechanism to achieve synchronous operation with the conveyor belt 95. The distance between the cleaning brush 97 and the surface of the conveyor belt 95 can be adjusted by adjusting bolts to ensure that the tool surface can be effectively cleaned without damaging the tool.

[0055] In this embodiment, the drawer 6 is provided with a drive groove 913 inside. The drive groove 913 is located inside the drawer 6 near its pull-out opening 61 and is used to install the relevant components of the lifting unit. The lifting unit includes a lifting plate 915 and a fifth telescopic member 914 that drives its lifting. The fifth telescopic member 914 is an electric push rod and is fixed in the drive groove 913. The lifting plate 915 is connected to the output end of the fifth telescopic member 914 through a linear guide rail to ensure the smoothness of the lifting process. The weighing sensor (not shown in the figure) is a high-precision strain sensor and is embedded in the lifting plate 915.

[0056] In this embodiment, a storage slot 916 is provided on the side of drawer 6 near its pull-out opening 61. The storage slot 916 is used for the fourth telescopic member 911 to ensure the stable operation of the pushing unit. The pushing unit includes a push plate 912 and a fourth telescopic member 911 that drives its horizontal movement. The fourth telescopic member 911 is an electric push rod and is fixed in the storage slot 916 inside the drawer 6. The push plate 912 is connected to the output end of the fourth telescopic member 911 and can move horizontally back and forth above the lifting plate 915.

[0057] The displacement drive unit includes a third telescopic member 99, which is an electric push rod fixed to the bottom of the drawer 6. The output end of the third telescopic member 99 is connected to the bearing seat 91 of the transmission unit through a connecting block 910, which can drive the entire transmission unit to move in a direction close to or away from the second inlet / outlet 98.

[0058] like Figure 6 and Figure 7As shown, each drawer 6 inside the cabinet 1 is provided with a locking mechanism 8. In this embodiment, the cabinet 1 is provided with several sets of limiting grooves 81, and each set of limiting grooves 81 has two locking mechanisms. The locking mechanism 8 includes a second telescopic member 82, a telescopic cylinder 83, a second spring 84 and a locking rod 85 provided in the limiting groove 81, and a locking hook 86 provided on the drawer 6. The second telescopic member 82 is an electric push rod. The second telescopic member 82 is fixedly connected to the cabinet 1. The telescopic cylinder 83 and the second spring 84 are fixed to the bottom of the second telescopic member 82. The other end of the telescopic cylinder 83 and the second spring 84 are fixedly connected to the locking rod 85. That is, the locking rod 85 is connected to the output end of the second telescopic member 82 through the telescopic cylinder 83 and the second spring 84 to form an elastic buffer structure. The locking hook 86 is fixed on the side of the drawer 6 away from the pull-out opening 61. Each set of locking hooks 86 has two hooks, which are provided corresponding to the limiting grooves 81.

[0059] Inside the box 1, each drawer 6 is provided with a pop-out auxiliary component. The pop-out auxiliary component includes a storage slot 14, a first spring 15, and a stop plate 16. The first spring 15 is a compression spring, with one end fixed to the box 1 and the other end connected to the stop plate 16. The stop plate 16 is slidably connected to the box 1 via a slide rail, and its front end is in contact with the rear end face of the drawer 6.

[0060] When drawer 6 needs to be opened, the control module controls the second telescopic component 82 to extend, driving the locking rod 85 to move downward and disengage from the locking hook 86. At the same time, the abutment plate 16 pushes the drawer 6 outward a certain distance under the elastic force of the first spring 15, providing operating space for the user. When closing drawer 6, the user applies appropriate pushing force, the locking hook 86 presses the locking rod 85 downward, compressing the second spring 84. After the locking hook 86 passes the locking rod 85, the second spring 84 rebounds, causing the locking rod 85 to automatically engage with the locking hook 86, completing the locking process.

[0061] When drawer 6 is closed, as drawer 6 inside the opening of box 1 is pushed toward the locking mechanism 8, due to the presence of telescopic cylinder 83 and spring 2, when the locking hook 86 moves toward the locking rod 85, under the action of the locking hook 86, the locking hook 86 can first drive the locking rod 85 downward, stretch the telescopic cylinder 83 and stretch the second spring 84, so that the locking hook 86 is hooked on the locking rod 85; then the second spring 84 retracts under the action of the pulling force, realizing the limiting of the locking rod 85 on the locking hook 86; At the same time, under the interaction force, the drawer 6 pushes the stop plate 16 to compress the first spring 15, so that the left end of the stop plate 16 is flush with the inner end face of the opening of the box 1, and the stop plate 16 and the first spring 15 are completely stored in the storage slot 14.

[0062] When drawer 6 needs to be pulled out, the second telescopic component 82 extends, causing the telescopic cylinder 83, the second spring 84, and the locking rod 85 to move downwards. This releases the locking rod 85 from the lock hook 86, while the abutment plate 16 releases the force. Under the elastic force of the first spring 15, the abutment plate 16 moves away from the first spring 15, thereby pushing drawer 6 away from the first spring 15. This assists in opening drawer 6, making it easier for staff to inspect and use the tools inside drawer 6, and thus enabling the opening and closing of the smart toolbox.

[0063] like Figure 1 and Figure 2 As shown, it also includes an environmental control system, which includes two sets of air pipes 17, an air pump (not shown in the figure) connected to the air pipes 17, and at least one of a temperature control device, a dehumidification device, and a filtration device (not shown in the figure) connected in series on the air pump. In this embodiment, the air pipe 17 is located at the top of the opening of the housing 1 and is connected to the air pump through a pipeline; the temperature control device uses a semiconductor cooling chip, which can realize dual functions of heating and cooling; the dehumidification device uses a rotary dehumidifier; the filtration device uses a HEPA high-efficiency filter; in this embodiment, the air pump is a dual-purpose air pump that can both draw and deliver air, including but not limited to a double-headed diaphragm pump or a reversible piston pump / vortex pump, which can switch the airflow direction according to the instructions of the control module to realize air circulation and temperature and humidity regulation inside the drawer 6.

[0064] The implementation principle of Example 1 is as follows: The RFID-controlled smart toolbox achieves automated tool retrieval and status monitoring through the coordinated operation of mechanical structure and intelligent control system. The system is based on the box body 1 as the basic support structure, with multiple independent drawer units 6 inside. The position adjustment mechanism 9 integrated in each drawer 6 forms a multi-dimensional motion control system through the coordinated operation of the transmission unit, lifting unit, pushing unit and displacement drive unit. The control module, as the system brain, identifies the tool's identity information through the reader 5 and coordinates the various actuators to complete the positioning and transfer of the tool. Under the unified scheduling of the control module, the tool is accurately positioned and transferred, thereby greatly shortening the tool retrieval time and greatly improving work efficiency. Furthermore, it innovatively embeds a weighing sensor into the automated process, using high-precision weight detection to identify minute wear and impurities on the tools, providing accurate information for tool maintenance. At the same time, the environmental control system, through the intelligent coordination of temperature and humidity sensors, air pumps, and functional devices, provides the best storage environment for the tools, effectively extending their service life.

[0065] Example 2 This application discloses a method for using an RFID-controlled smart toolbox as described in Embodiment 1, the method comprising the following steps: Tool entry registration: Attach electronic tags to the tools and place them on the position adjustment mechanism 9, and register the tool information and its standard weight in the control module; Tool lending: In response to user operation, the control module controls the position adjustment mechanism 9 to move the target tool to the tool transfer channel, and obtains and records the lending weight through the weighing sensor; Tool return: The control module identifies the electronic tag of the tool to be returned, controls the opening of the corresponding tool transfer channel, and obtains and records the weight of the tool after the user puts it in. Status judgment: The control module compares the returned weight with the borrowed weight or the standard weight, and judges whether the physical state of the tool is abnormal based on the weight change.

[0066] The following sections will provide a detailed explanation of each step.

[0067] The specific process for tool registration and warehousing is as follows: Staff opened drawer 6 and affixed electronic tags to the tools that needed to be managed; each electronic tag stored basic information such as the tool's unique identification code and specifications. The tools with attached electronic tags are placed on the conveyor belt 95 in sequence and fixed by the adsorption component 96. The adsorption component 96 adopts an electromagnet or a vacuum suction cup to ensure that the tools remain stable during the conveying process. Enter detailed tool information via touchscreen 4, including: tool name and specifications, standard weight Gi (in grams), allowable weight deviation Mi (in grams), and service life threshold Ni (times). The control module automatically records the position coordinates of each tool on the conveyor belt 95, establishes a complete tool position database, and the system drives the conveyor belt 95 to rotate through the motor 92, and determines the accurate position of each tool in conjunction with the position sensor. After drawer 6 is closed, the system automatically completes the initial registration of the tool and saves a complete tool file in processor 3, including basic tool information, weight parameters, location information, and usage records.

[0068] The specific process for borrowing tools is as follows: Users can initiate the borrowing process in either of the following ways: directly select the tool to be borrowed on the touchscreen 4; or swipe their identity card on the reader 5 to verify their identity and then select the tool from the list of authorized tools. After receiving the loan instruction, the processor 3 of the control module executes the following automated operation sequence: First, control the locking mechanism 8 to unlock the corresponding drawer 6. Then, the second telescopic component 82 extends, driving the locking rod 85 to move downward and disengage from the locking hook 86. At the same time, the abutment plate 16 pushes the drawer 6 outward under the action of the spring to assist in opening. Next, control the third telescopic member 99 to drive the entire transfer unit to move, and align the target tool with the center position of the lifting plate 915 through position control; Then, control the motor 92 to start, and the conveyor belt 95 runs at a preset speed to smoothly move the target tool directly above the lifting plate 915; the suction attachment 96 is powered off and released, and the tool freely falls onto the lifting plate 915. The weighing sensor immediately obtains the lent weight gi, and the processor 3 records and stores this weight data; Subsequently, control the fifth telescopic member 914 to descend smoothly so that the top surface of the lifting plate 915 is flush with the bottom edge of the second inlet / outlet 98; Finally, control the first telescopic member 13 to contract, open the electric door 12 to form a complete tool transfer path, control the fourth telescopic member 911 to extend, and drive the push plate 912 to smoothly push the tool out of the box body 1 through the tool transfer channel; The processor 3 counts this lending, and at the same time records complete information such as the lending time, the lending personnel, and the tool status, and establishes a complete lending file.

[0069] The specific process of tool return is as follows: The user brings the tool electronic tag close to the reader 5, and the control module automatically identifies the tool information and performs the following operations: After the reader 5 identifies the electronic tag of the tool, it verifies the correctness of the attribution of the corresponding tool and determines the corresponding tool transfer channel; Control the electric door 12 of the corresponding drawer 6 to open, and the user places the tool into the tool transfer channel, and the tool is automatically placed on the lifting plate 915; The weighing sensor obtains the return weight gi', and records the data after ensuring stable measurement; The counting module records the return times ni', and updates the tool usage statistics.

[0070] The status judgment mainly starts a three-level status judgment program through the control module, which is specifically as follows: The first-level return situation judgment: The processor 3 compares the numerical relationship between the lending count ni and the return count ni'; Normal situation: ni = ni', it is determined that the tool has been returned, and enter the second-level judgment; Abnormal situation: ni ≠ ni', it is determined that the tool has not been returned, control the warning light 7 to emit a double-flash alarm, and at the same time display the specific unreturned tool information on the touch screen 4, including the tool name, lending time and responsible person.

[0071] The second-level usage times judgment: The processor 3 compares the return count ni' with the preset maintenance threshold Ni: Normal situation: ni' < Ni, it is determined that the tool can continue to be used, and enter the third-level judgment; Early warning situation: When ni'≥0.8Ni, the system issues a mild early warning. Alarm situation: When ni'≥Ni, it is determined that the tool needs to be repaired. Control the warning light 7 to stay on continuously, and display a prompt message on the touch screen 44 indicating that the tool has reached its usage cycle and needs to be repaired in a timely manner.

[0072] Judgment of the usage situation at the third level: The processor 3 calculates the weight change amount Δg = |gi' - gi| and makes an accurate comparison with the allowable weight deviation Mi / Ni per single use: Normal state: Δg≤Mi / Ni, it is determined that the tool is in a normal state and can continue to be used; <000,0228>Abnormal adhesion: gi'>gi + Mi / Ni, it is determined that the tool is adhered with debris, and the cleaning program is automatically started: control the cleaning brush 97 to operate, and mechanically brush the surface of the tool; at the same time, start the environmental control system, and the dual-purpose air pump generates a negative pressure air flow, and sucks and removes dust through the air pipe 17; after the cleaning is completed, reweigh and detect. If the weight returns to normal, the cleaning process is completed; Abnormal wear: gi'<gi - Mi / Ni, it is determined that the tool has wear or damage, control the warning light 7 to flash once for alarm, and display a warning message on the touch screen 4 indicating abnormal wear of the tool and please check and replace.

[0073] In this embodiment, the usage method further includes monitoring the usage times, and the specific implementation process is as follows: Establish a complete usage file for each tool and implement preventive maintenance: Real-time statistics of the usage times ni' of each tool, and establish a usage frequency analysis model; When ni' is close to 80% of the maintenance threshold Ni, the system issues an early warning prompt in advance; When ni' reaches Ni, the system forcibly prompts for maintenance and marks the to-be-maintained status in the tool file; After the maintenance is completed, an authorized person performs a maintenance confirmation operation on the touch screen 4, resets the usage count, and updates the maintenance record.

[0074] In this embodiment, the usage method further includes monitoring the overdue return. Timing starts when the tool is lent out, and hierarchical monitoring measures are implemented: Set a three-level early warning mechanism: Primary early warning: When lent out for 8 hours, the system issues a gentle reminder (the warning light 7 flashes slowly); Intermediate early warning: When lent out for 24 hours, the system issues a formal warning (the warning light 7 flashes at medium speed); Advanced early warning: When lent out for 48 hours, the system issues a serious alarm (the warning light 7 flashes quickly and gives a sound prompt); The touchscreen 4 displays a list of overdue and unreturned tools in real time, including tool information, lending time, and responsible person. The system automatically records all timeout events and generates management reports, providing data support for tool management optimization.

[0075] In this embodiment, the method of use also includes environmental monitoring. The environmental control system operates automatically based on real-time monitoring data. In this embodiment, the housing 1 is equipped with a temperature sensor and a humidity sensor. Temperature control: When the temperature sensor detects that the ambient temperature exceeds the set range (default: 15-30℃), the temperature control device will be automatically activated; Humidity control: When the humidity sensor detects that the humidity is too high (>60%RH), the dehumidification equipment will be automatically started; Cleaning and maintenance: Regularly turn on the filtration equipment to keep the air inside the toolbox clean; Data logging: The system records the changing trends of environmental parameters, providing data support for optimizing the tool's storage environment.

[0076] Through the above comprehensive tool management methodology, the entire process from tool entry, borrowing, and return to status monitoring is automated, ensuring the safety, reliability, and long-term effectiveness of tool use. Each step is tightly integrated, forming a complete closed-loop tool lifecycle management system.

[0077] The implementation principle of Example 2 is as follows: Based on the hardware platform of Example 1 (RFID-controlled smart toolbox), this example constructs a complete intelligent management system for the tool lifecycle. Through data-driven, end-to-end digital management, it achieves refined control over the tool usage process. The system establishes a complete data chain from tool registration and borrowing to return evaluation. Based on usage statistics and weight change trend analysis, a preventive maintenance mechanism is constructed. This innovation significantly reduces the tool failure rate and effectively extends its service life. The intelligent decision-making system automatically judges the tool status and triggers corresponding processing procedures based on preset rules and real-time data. Combined with the implementation of a graded early warning strategy, it greatly reduces the risk of tool-related safety accidents. The system continuously optimizes management strategies through the accumulation of usage and environmental data. The resulting self-improving intelligent management system not only greatly reduces the workload of management personnel, but also provides a scientific basis for tool procurement, maintenance, and update decisions through complete analysis reports. The intuitive visualization interface and intelligent prompts further enhance the user experience. Together, these two examples constitute a complete intelligent tool management solution, achieving a leapfrog development from traditional tool management to intelligent full lifecycle management.

[0078] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
