[0002] At present, in aircraft assembly production tasks, there are various types and large quantities of tools used. However, the traditional tool management mode is still adopted. On-site workers need to go to fixed tool placement points to pick up and return tools, which consumes a large amount of labor costs and has low information control efficiency. In addition, each work package delivery station adopts closed management to control excess materials. Due to the poor tracking and tracing control of the current tool management method, there is a certain risk of excess material control. Summary of the Invention

[0003] To solve the above problems, the present invention provides an automatic distribution tool management cabinet and a tool management method.

[0004] The specific technical solution of the present invention is as follows:

[0005] An automatic distribution tool management cabinet includes a cabinet body 2, an AGV trolley 1, and an identity authentication terminal 3. The cabinet body 2 is fixedly installed on the AGV trolley 1, and the identity authentication terminal 3 is fixed on the cabinet body 2.

[0006] The cabinet body 2 includes a housing 4, a cabinet door 5, a door lock mechanism 6, a fixed shelf 7, a weighing sensor 8, a tray 9, and a main controller 10.

[0007] A plurality of fixed shelves 7 are arranged in the housing 4 to divide the interior of the cabinet body 2 into different storage spaces. One side of the cabinet door 5 is connected to the edge of the front end face of the housing 4 through a hinge. The middle part of the other side of the cabinet door 5 is provided with a door lock mechanism 6, and the door lock mechanism 6 is magnetically adsorbed and connected to the housing 4.

[0008] Weighing sensors 8 are fixedly installed on each fixed shelf 7. A plurality of trays 9 of different sizes are placed on the weighing sensors 8 and are in contact connection with the weighing sensors 8. Each tray 9 is used to store designated tools, and the weight changes of each tray 9 are obtained through the weighing sensors 8.

[0009] The main controller 10 is installed inside the housing 4 and is electrically connected to the door lock mechanism 6, the weighing sensor 8, the AGV cart 1, and the identity authentication terminal 3. The main controller 10 is configured with a wireless communication module, an AGV control module, a door lock control module, an authorization control module, and a tool management module, and these modules are electrically connected to each other. The wireless communication module is used to receive the call instruction of the AGV cart 1 in real time and transmit it to the AGV control module, and send the tool statistics information to the general tool library to realize the real-time tracking of the tool status information. The general tool library regularly reminds of the unreturned information to prevent tools from being left on the aircraft product. The AGV control module stores the position information of each work station, the planned route information for arriving at and returning to this work station, and the control information of the AGV cart 1, and is used to receive the call instruction of the wireless communication module and control the AGV cart 1 to run according to the instruction. The authorization control module stores the personnel information of those authorized to use the cabinet 2, is used to judge whether to allow authorization authentication, and transmits the approved authorization signal to the door lock control module. The door lock control module is used to control the door lock control mechanism 6 according to the approved authorization signal of the authorization control module. The tool management module stores the total weight of tools, the weight of a single tool, the tool information stored in each tray 9, and the tool access record, and is used to judge the tool access and return information through the signal of the weighing sensor 8 and record it, judge whether the tool is returned incorrectly and alarm, and at the same time send the tool status information to the general tool library through the wireless communication module.

[0010] The identity authentication terminal 3 described above is used to identify face information, transmit it to the authorization control module of the main control system 10 through an electrical signal. After information comparison, the authorization control module judges whether to authorize and transmits the authorization signal to the door lock control module and the tool management module.

[0011] A tool management method is realized based on the above automatic tool delivery management cabinet, and includes the following steps:

[0012] Step 1, the wireless communication module of the main controller 10 receives the call instruction of the AGV cart 1 in real time and transmits it to the AGV control module;

[0013] Step 2, after the AGV control module receives the call instruction transmitted by the wireless communication module, it transmits the planned route to the AGV cart 1, and the AGV cart 1 arrives at the specified work station as required. After the AGV cart 1 arrives at the specified work station and stops stably, the AGV control module transmits the stop state to the authorization control module of the main control system 10 through an electrical signal.

[0014] Step 3, after the authorization control module receives the stop state signal, it allows the authorization authentication operation; the identity authentication terminal 3 identifies face information, transmits it to the authorization control module through an electrical signal, the authorization control module compares it with the stored personnel information to judge whether to authorize, and sends the approved authorization signal to the door lock control module.

[0015] Step 4, after receiving the authorization approval from the authorization control module, the door lock control module transmits the door opening permission signal to the door lock control mechanism 6. The door lock control mechanism 6 releases the magnetic adsorption to open the cabinet door 5 and transmits the authorization information to the tool management module.

[0016] Step 5, after receiving the authorization information, the tool management module records the information of the authorized person, obtains the weight change information of each tray 9 through the weighing sensor 8 and judges the tool access information. Specifically: when the weighing sensor 8 transmits a decrease in weight, compare the decreased weight with the weight of a single tool in the corresponding tray 9 to determine the number of tools decreased, and record the tool access status information under this authorized person's information and store it; when the weighing sensor 8 transmits an increase in weight, compare the increased weight with the single weight in this tray 9. If it is not an integer multiple relationship with the single weight, it is considered that the wrong tool is returned and an alarm is given. If it is an integer multiple relationship with the single weight, compare it with the information of the borrower of this tool recorded in the tool management module. If they are the same, it is determined that the tool is returned and the information is recorded. If they are different, it is considered that the tool is returned wrongly and an alarm is given; the wireless communication module real-time transmits the tool access and return information to the general tool library to realize automatic statistics of tool status and periodically remind of the unreturned information.

[0017] Step 6, after the tool is accessed or returned, close the cabinet door 5. The tool management module transmits the access completion information to the door lock control module through an electrical signal. After receiving the access completion signal, the door lock control module re-controls the door lock mechanism 6 to lock the cabinet door 5 and transmits the door closing status information to the AGV control module through an electrical signal.

[0018] Step 7, after receiving the cabinet door 5 closing signal, the AGV control module transmits a control signal to the AGV cart 1. After receiving this signal, the AGV cart 1 performs a return operation and returns to the original position according to the planned route to wait for the next call instruction.

[0019] Advantages of the present invention: The present invention reduces the waste of man-hours in the process of on-site staff borrowing and returning tools; at the same time, the tool management realizes automatic statistics, reduces personnel costs, and improves the tool management and data statistics efficiency.

[0030] The identity authentication terminal 3 described above is used to recognize face information, transmit it to the authorization control module of the main control system 10 through an electrical signal. After information comparison, the authorization control module judges whether to authorize, and transmits the authorization signal to the door lock control module and the tool management module.

[0031] A tool management method is realized based on the above automatic distribution tool management cabinet, and includes the following steps:

[0032] Step 1, the wireless communication module of the main controller 10 receives the call instruction of the AGV cart 1 in real time and transmits it to the AGV control module;

[0033] Step 2, after the AGV control module receives the call instruction transmitted by the wireless communication module, it transmits the planned route to the AGV cart 1, and the AGV cart 1 reaches the specified work station as required. After the AGV cart 1 reaches the specified work station and stops stably, the AGV control module transmits the stop state to the authorization control module of the main control system 10 through an electrical signal.

[0034] Step 3, after the authorization control module receives the stop state signal, it allows the authorization authentication operation; the identity authentication terminal 3 recognizes face information, transmits it to the authorization control module through an electrical signal, the authorization control module compares it with the stored personnel information to judge whether to authorize, and sends the approved authorization signal to the door lock control module.
