Description

Technical Field

[0001] This invention belongs to the field of enterprise tool asset control technology, and in particular relates to a tool priority outbound control method based on radio frequency reading technology. Background Technology

[0002] Electric and pneumatic tools are essential assets used by manufacturing personnel. How to improve tool utilization and rationally allocate tool resources while ensuring their use in manufacturing operations is an important issue in the field of factory resource cost management and control.

[0003] Currently, the control over the requisition of electric and pneumatic tools in enterprise internal resource management is limited to intelligent control from the external supply chain to the factory. The lack of intelligent control at this stage means that tools will be temporarily stored on the production line after being requisitioned. This deficiency leads to expired warranties and loss of free after-sales service, increasing tool repair costs. Uncontrolled tools, once used in production, may suffer unknown damage, impacting production efficiency and operator experience. Furthermore, disordered tool requisition makes it impossible to control the true lifespan of each tool, resulting in excess tools on the production line, causing resource waste, increased operating costs, and operational risks. Summary of the Invention

[0004] This invention provides a tool priority outbound control method based on radio frequency reading technology to intelligently control the actual demand for tools, and to solve problems such as on-line tool inventory control and warranty period compliance control for enterprises. It mitigates management risks, improves user tool usage efficiency and experience, and fully extracts operational data for data mining, providing support for efficient enterprise operations.

[0005] The technical solution adopted by this invention includes the following steps:

[0006] S1. Obtain tool type file information and establish a basic data dataset of tool types;

[0007] S2. Obtain the ordering information and unique serial number of the tool for this type of tool, assign an RFID tag, establish basic information for a single tool, and establish or update the tool ledger.

[0008] S3. Obtain tool type file information for the workstation and establish a basic data dataset of workstation tool types;

[0009] S4. Obtain the allocation information of storage location tools for intelligent warehousing equipment and establish a tool storage allocation dataset;

[0010] S5. Obtain maintenance information for single-tools and establish a single-tool history dataset;

[0011] S6. Based on the tool type basic data dataset, single tool basic information and tool ledger dataset, workstation tool type basic data dataset, tool storage and allocation dataset, and single tool history dataset collected in S1-S5, establish a priority inbound and outbound allocation control model; when a tool triggers a requisition requirement, allocate the priority tool to complete the tool requisition control and achieve effective and economical use of tools.

[0012] In S1 of this invention, when a tool is newly imported, a basic file for the tool type is set. The information in the tool type file includes basic information about the tool, the warranty period of the new tool, the department that established it, the tool manufacturer, the supplier, and the repair service provider. Among them, the basic information includes the tool order code, name, repair service provider, product model, exploded diagram of product components, product components including serial numbers, component models, and component repair service warranty period.

[0013] The tool ordering information in S2 of this invention includes tool order code, tool order code, warehousing date, outbound date, ordering organization, and ordering personnel; the unique number includes the factory code or an identifier to ensure the uniqueness of the tool, adding a new tool ledger information, generating a single tool history, the history includes the ordering information of all tools and the file information of the tool type, the expiration date of the new tool's warranty period, the warranty period of the component repair service, automatically assigning a unique system code to the tool, and issuing an RFID tag code.

[0014] The tool type file information of the workstation in S3 of this invention includes each production workstation in the enterprise's manufacturing process and the types of tools required thereto, as well as the storage location of the spare tools in the intelligent storage device.

[0015] In S4 of this invention, the information on the allocation of tools in the storage location of the intelligent warehousing equipment is obtained, including the location information of the cabinet or the compartment of the cabinet to which the production workstation of the enterprise is located, and the tools are allocated to different storage locations according to the type and quantity of tools in the workstation. The tool handover is realized through the intelligent cabinet.

[0016] The maintenance information of a single tool obtained in S5 of this invention includes creating a tool repair work order, collecting tool repair information, and updating the tool status information in the tool ledger: in use, under repair, in standby, or scrapped. The repair work order records the repair completion date of each tool, the replaced components and their repair service warranty period, and collects them in the single tool history, updating the expiration date of the repair service warranty period of the replaced components in the tool history.

[0017] The S6 of this invention includes the following steps:

[0018] S61. Based on the collected tool type basic data dataset, tool ledger history dataset, tool type basic data dataset, and tool cabinet allocation dataset, establish a tool inbound and outbound allocation management dataset.

[0019] S62. Based on the tool in / out allocation management dataset, establish a tool priority in / out allocation control model;

[0020] S63. When picking up tools, enter the workstation and tool type information of the required tools, perform priority outbound allocation calculation, and pick up the tools.

[0021] The S63 priority outbound allocation calculation method includes the following steps:

[0022] S631. Retrieve the list of tool types for the tool station and match the list of applicable tools within the current smart warehouse location;

[0023] S632. The tools that have been retrieved are sorted according to their retrieval order. The steps for calculating the sorting order are as follows:

[0024] Step 1: Prioritize the use of new tools, and select tools that are still under warranty. The number of tools of the same specification under warranty is N, and the target tool is k. The warranty expiration dates for each new tool are T1, T2, T3, ..., T N T represents the current time. If N ≥ 1, the tool with the shortest remaining warranty period is selected as the priority for shipment: minimum remaining warranty period T. Min =Min{(T1-T),(T2-T),……,(T N -T)}=(T k -T);

[0025] If N<1, filter by the minimum remaining warranty period based on unit repair cost, as follows:

[0026] Let N' be the number of identical tools outside the warranty period of the new tool, N' ≥ 2, the tool serial number be i (i = 1, 2, ..., N'), and the component serial number be j (j = 1, 2, ..., M). Let C be the repair and replacement cost of the j-th component. j The warranty period for the j-th component of the i-th tool expires at time T. ij T represents the current time, and τ represents the unit repair cost and the remaining warranty period.

[0027] The formula is:

[0028] Let it be 0;

[0029] If N'≧2, then the tool with the smallest remaining warranty period for unit repair cost and not 0 is selected as the priority tool for delivery. If τ=0, it means that all components of the tool have exceeded the repair warranty period, then the tool with the remaining warranty period has not expired is selected first.

[0030] If τ k =τ min =Min{τ1, τ2, ..., τ N′}

[0031] Then tool number k is the priority outbound tool;

[0032] If k is not unique, the tool with the largest cumulative service load (e.g., the cumulative service load of wrenches is counted according to the number of blows) will be given priority for removal from the warehouse. If the service time is the same, the system will randomly assign the tool.

[0033] Step 2: Retrieve the tool cabinet and compartment information where tool K is located, and grant tool retrieval permissions;

[0034] S633. Click to claim. The tool will open the cabinet door for the tool to be claimed. Take out the tool and perform an RFID scan to confirm the match. If the match is correct, the claim is successful and the tool log status is updated. If the match is incorrect, an error will be reported and you will be prompted to replace the tool and try to claim and match again. If the match is correct, the claim is successful.

[0035] The positive effects of this invention are:

[0036] It can acquire tool file information, status data, maintenance data, and warranty period data, monitor the tool's repair and warranty status, and push priority delivery usage plans to reduce the risk of improper tool requisition affecting production efficiency. Minimizing warranty period calculations can also reduce tool maintenance costs. Optimized calculations based on accumulated load exceeding the warranty period accelerate the replacement and iteration of older tools, thereby reducing over-ordering and stockpiling of spare equipment due to surplus old tools. Simultaneously, by binding smart devices to tool usage ports, it avoids information silos, visually aggregating all data into the management system. This improves work efficiency, reduces operating costs, and mitigates business risks for enterprises. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0039] Includes the following steps:

[0040] S1. Obtain tool type file information and establish a basic data dataset of tool types;

[0041] S2. Obtain the ordering information and unique serial number of the tool for this type of tool, assign an RFID tag, establish basic information for each tool, and establish or update the tool ledger;

[0042] S3. Obtain tool type file information for the workstation and establish a basic data dataset of workstation tool types;

[0043] S4. Obtain the allocation information of storage location tools for intelligent warehousing equipment and establish a tool storage allocation dataset;

[0044] S5. Obtain maintenance information for single-tools and establish a single-tool history dataset;

[0045] S6. Based on the tool type basic data dataset, single tool basic information and tool ledger dataset, workstation tool type basic data dataset, tool storage and allocation dataset, and single tool history dataset collected in S1-S5, establish a priority inbound and outbound allocation control model; when a tool triggers a requisition requirement, allocate the priority tool to complete the tool requisition control and achieve effective and economical use of tools.

[0046] When a tool is newly imported in S1, a basic file for the tool type is set. The information in the tool type file includes the tool's basic information, the new tool's warranty period, the department that established it, the tool manufacturer, the supplier, and the repair service provider. Among them, the basic information includes the tool order code, name, repair service provider, product model, exploded view of the product components, and product components (including number, component model, and component repair service warranty period).

[0047] In this embodiment, obtaining the initial information of the tool enables subsequent maintenance of the tool, management of entry and exit from the warehouse based on the archive information, and data classification, thereby avoiding data discrepancies in the use of the tool in multiple situations.

[0048] The tool ordering information in S2 includes tool order code, tool order code, warehousing date, outbound date, ordering organization, and ordering personnel; the unique number includes the factory code or an identifier that ensures the uniqueness of the tool, adds a new tool ledger entry, generates a single tool history, the history includes the ordering information of all tools and the file information of the tool type, the expiration date of the new tool's warranty period, the warranty period of the component repair service, automatically assigns a unique system code to the tool, and issues an RFID tag code.

[0049] In this embodiment, the uniqueness of each tool is obtained, the expiration date of the warranty period for the new tool is calculated, and the warranty period for the repair service of each component is synchronized. This is then calibrated during later use and maintenance processes to ensure the accuracy of tool acquisition.

[0050] The tool type file information of the workstation in S3 includes each production workstation in the enterprise's manufacturing process and the types of tools required (such as impact wrenches), as well as the storage location of the spare tools in the intelligent storage device.

[0051] In this embodiment, the workstations are matched one-to-one with the tools they use, and the actual necessary number of tools and the service load of the tools are determined.

[0052] In step S4, the allocation information of storage location tools of intelligent warehousing equipment is obtained, including the location information of the cabinet or the compartment of the cabinet to which the production workstation of the enterprise is located to store spare tools. The tools are allocated to different storage locations according to the type and quantity of tools in the workstation. Tool handover is realized through intelligent cabinets.

[0053] In this embodiment, the interaction and control between the various control components of the intelligent warehousing equipment, the intelligent warehousing equipment control system, and the tool management main control system can be achieved using languages ​​such as JAVA and C#. The cloud server hosting the main management control system controls and retrieves the hardware control port program of the equipment, which can reduce the repetitive development caused by the diverse changes in hardware devices. The radio frequency reading and receiving antennas configured in the intelligent warehousing equipment compartments are used to receive tool information stored in the compartments. This information is controlled by the intelligent warehousing equipment control system and transmitted to the cloud server for data retrieval and use. Obtaining the storage location and tool correspondence information of the intelligent warehousing equipment avoids storage errors and prepares for subsequent tool allocation.

[0054] In step S5, the maintenance information for a single tool is obtained, including creating a tool repair work order, collecting tool repair information, and updating the tool status information (in use, under repair, in standby, scrapped, etc.) in the tool ledger. The repair work order records the repair completion date for each tool, the replaced components, and their warranty period, and is compiled into the single tool history, updating the expiration date of the warranty period for the replaced components in the tool history.

[0055] In this embodiment, the tool's status information and warranty period are obtained to accurately grasp the tool's condition and avoid asset loss and repair cost losses caused by missing information.

[0056] S6 includes the following steps:

[0057] S61. Based on the collected tool type basic data dataset, tool ledger history dataset, tool type basic data dataset, and tool cabinet allocation dataset, establish a tool outbound allocation management dataset.

[0058] S62. Based on the tool outbound allocation management dataset, establish a tool priority outbound allocation control model;

[0059] S63. When picking up tools, enter the workstation and tool type information of the required tools, perform priority outbound allocation calculation, and pick up the tools.

[0060] In this embodiment, the priority inbound and outbound allocation control model established through deep learning can effectively avoid the waste of maintenance costs caused by tools that are still under warranty being idle for a long time.

[0061] The S63, priority outbound allocation calculation method includes the following steps: ( Figure 1 )

[0062] S631. Retrieve the list of tool types for the tool station and match the list of applicable tools within the current smart warehouse location.

[0063] S632. The tools that have been retrieved are sorted according to their retrieval order. The steps for calculating the sorting order are as follows:

[0064] Step 1: Prioritize the use of new tools and select tools within their warranty period. Let N be the number of tools of the same specification within their warranty period, and k be the target tool. The warranty expiration dates for each new tool are T1, T2, T3, ..., TN; where T is the current time. If N ≥ 1, select the tool with the shortest remaining warranty period as the priority for shipment: minimum remaining warranty period T. Min =Min{(T1-T),(T2-T),……,(T N -T)}=(T k -T).

[0065] If N < 1, filter by the minimum remaining warranty period per unit repair cost. The method is as follows:

[0066] Let N' be the number of identical tools outside the warranty period of the new tool (generally N'≥2). Let the tool serial number be i (i=1,2,…,N'), and the tool component serial numbers be j (j=1,2,…,M) (e.g., j=1 is a motor, j=2 is a gear, etc.). Let C be the repair and replacement cost of the j-th component. j The warranty period for the j-th component of the i-th tool expires at time T. ij T is the current time (T ij When -T≤0, then let it be 0), the unit maintenance cost and remaining warranty period τ

[0067] The formula is:

[0068] (where T) j When -T≤0, then set it to 0)

[0069] If N'≧2, then the tool with the smallest remaining warranty period for unit repair cost and not 0 is selected as the priority tool for delivery (if τ=0, it means that all components of the tool have exceeded the repair warranty period, then the tool with the remaining warranty period has not expired is selected first).

[0070] If τ k =τ min =Min{τ1, τ2, ..., τ N′}

[0071] Then tool number k is the priority outbound tool.

[0072] If k is not unique, the tool with the largest cumulative service load (e.g., the cumulative service load of wrenches is counted according to the number of blows) will be the priority tool to be removed from the warehouse. If the service time is the same, the system will randomly assign the tool.

[0073] Step 2: Retrieve the tool cabinet and compartment information where tool K is located, and grant tool retrieval privileges.

[0074] In this embodiment:

[0075] Example Scenario 1: There are N=3 new tools of the same specification within their warranty period. The warranty expiration dates for each new tool are: Tool 1, October 20th (cabinet 1, compartment 2); Tool 2, October 29th (cabinet 1, compartment 3); Tool 3, November 5th (cabinet 1, compartment 2). The current date is September 1st. Select target tool k.

[0076] The first step involves performing a condition-based evaluation. If N ≥ 1, and condition 1 is met, tools within the warranty period are selected based on the principle of prioritizing the use of newer tools. The minimum remaining warranty period T is then determined. Min ={T1, T2, T3} = {50, 59, 66} = 50, meaning k is tool number 1.

[0077] Step 2: Retrieve the tool cabinet and compartment information where tool k (i.e., tool number 1) is located, which is 1. # Tool cabinet and 2 # Number of slots, release tool to obtain permissions.

[0078] Example Scenario 2: The number of tools of the same specification within the warranty period of the new tool is N = 0, the number of tools of the same specification outside the warranty period of the new tool is N' = 3, the number of tool components is j = 3, and the component information and its maintenance and warranty period information are shown in Table 1. (Current time...)

[0079]

[0080] As of September 1st, the remaining warranty period (T) of the components calculated based on the current time. j -T)(as shown in Table 2), filter target tool k.

[0081]

[0082] The first step is to proceed to condition 1 for judgment. Since N < 1 does not meet the principle of prioritizing the use of new tools, proceed to condition 2 for judgment and selection, and select the tool with the lowest unit repair cost and the shortest remaining warranty period.

[0083] Minimum Remaining Warranty Period τ per Unit Repair Cost Min ={τ1, τ2, τ3} ={4.51, 5.19, 0} = 4.51, meaning k is tool number 1.

[0084] Step 2: Retrieve the tool storage information of the intelligent warehousing equipment (as shown in Table 3). The tool cabinet and compartment information where tool k, i.e., tool number 1, is located is 1. # Cabinet 1 # Release the tool access permissions for the specified grid.

[0085]

[0086] In this embodiment, the cost of using and maintaining tools during the warranty period can be reduced, and the obsolescence cycle of old tools can be accelerated, improving the user experience while reducing the inventory of spare tools.

[0087] S633. Click "Claim". The tool will open the cabinet door. Take out the tool and perform an RFID scan for matching and confirmation. If the match is correct, the tool will be successfully claimed, and the tool log status will be updated. If the match is incorrect, an error message will be displayed, prompting you to replace the tool and try to claim and match again. If the match is correct, the tool will be successfully claimed.

[0088] In this embodiment, intelligent methods can be used to avoid the risk of cost waste caused by human error.
