Description

Technical Field

[0001] This invention belongs to the field of server production management technology, specifically relating to a torque control system and method for electric screwdrivers in the server production process. Background Technology

[0002] With the increasing demand for servers, various product types have emerged, including general-purpose servers, rack servers, high-performance servers, and edge servers. Different server types further produce different models, resulting in a large number of server models. For server manufacturers, this means a very high frequency of switching work orders, models, and products during production. Frequent switching leads to changes in the work content at different workstations. Even work involving the use of electric screwdrivers may see changes. Some work content changes significantly, such as from assembling circuit boards to assembling hard drives; others change slightly, such as from assembling 3.5-inch mechanical hard drives to assembling 2.5-inch solid-state drives; still others remain unchanged, such as assembling different types of motherboards, even with the same motherboard screw part numbers and electric screwdriver torque requirements.

[0003] When a low-torque electric screwdriver is required during a production switch but a high-torque one is used instead, it can damage the screws, such as stripped screws, visible or invisible cracks in the motherboard's enlarged holes, resulting in material cost losses or damage to hidden components, ultimately reducing product lifespan. Currently, when switching production orders, manual verification of each electric screwdriver on the production line is required according to the SOP's torque requirements to ensure the correct torque value.

[0004] Incorrect torque values, especially excessively high ones, in electric screwdrivers can cause mass damage to components such as motherboards and hard drives. This damage is highly likely to be discovered only during the testing phase, or even after the product has been sold to the user, resulting in significant losses. Current methods of adjusting electric screwdriver torque values ​​increase production line work order changeover time, thereby increasing hidden costs. Furthermore, current methods of adjusting electric screwdriver torque values ​​cannot trace products using incorrect torque values.

[0005] Therefore, in order to address the above-mentioned shortcomings, it is essential to provide a torque control system and method for electric screwdrivers in the server manufacturing process. Summary of the Invention

[0006] To address the issues of material damage caused by incorrect torque values ​​in electric screwdrivers, particularly excessive torque, the current methods for adjusting electric screwdriver torque values ​​lead to increased production line work order changeover times and the inability to trace products using incorrect torque values, this invention provides a torque control system and method for electric screwdrivers in server production processes to solve the aforementioned technical problems.

[0007] In a first aspect, the present invention provides a torque control system for an electric screwdriver used in server manufacturing processes, comprising:

Each electric screwdriver torque value record includes the record number, screwdriver type, electric screwdriver serial number, torque value, start time, creator, creation time, torque value modifier, torque value modification time, and remarks. By using electric screwdriver archives, all electric screwdriver codes, torque values, and torque value modifications during the server production process can be traced back to the site and verification personnel, which helps improve product quality. Through unified management of electric screwdriver torque adjustment equipment, the overall number of electric screwdrivers used in the workshop is reduced, the idle rate of electric screwdrivers is significantly decreased, and equipment utilization is more efficient.

[0018] Furthermore, the model torque management module includes:

[0019] The model torque value information management unit is used to manage the addition, modification, deletion, and export of electric screwdriver torque value records for server models, and to generate electric screwdriver torque value files for each model.

[0021] The machine model torque value query unit is used to query and display the torque value records of electric screwdrivers corresponding to the server model in response to the user's input of machine model, electric screwdriver type, and torque value conditions. The torque value record of electric screwdrivers corresponding to the server model includes record number, screwdriver type, electric screwdriver number, torque value, start time of use, creator, creation time, person who modified the torque value, time of modification of the torque value, and remarks.

[0022] Furthermore, the electric screwdriver usage viewing module includes:

[0023] The electric screwdriver usage and management information unit is used to generate and manage electric screwdriver usage and management records based on electric screwdriver type, torque value, usage status, and management status.

[0024] The electric screwdriver usage and management information display unit is used to display the electric screwdriver usage and management records in a list format, item by item.

[0025] The electric screwdriver usage and management information query unit is used to query and display matching electric screwdriver usage and management records in response to user input of model, screwdriver type or torque value conditions;

[0026] The refresh unit is used to update the electric screwdriver usage and management records in response to user refresh requests or preset refresh cycles. The electric screwdriver usage and management records include the screwdriver serial number, production line, workstation, screwdriver type, torque value, usage status, whether it is on the management platform, and the person in charge. The electric screwdriver usage viewing module enables systematic management of electric screwdrivers, clearly presenting the usage status of each screwdriver. This data can be used for more accurate equipment management, analysis, spare parts replacement, and equipment maintenance.

[0027] Furthermore, the work order switching reminder module includes:

[0028] The reminder preset unit is used to pre-set the number of remaining machines when switching from the previous work order to the next work order. When the number of remaining machines is sufficient, the reminder interface is activated so that the production personnel can prepare the electric screwdriver.

[0029] The current work order model torque value information unit is used to display the current work order model, production line, work station, screwdriver type, and torque value information in a list format on the reminder interface;

[0030] The next work order machine type torque value information unit is used to display the next work order machine type, line, work station, screwdriver type and torque value information in a list on the reminder interface;

[0031] The difference display unit is used to compare the torque value information of the current work order model and the torque value information of the next work order model item by item and output whether there is a difference.

[0032] Furthermore, the electric screwdriver barcode scanning inspection module includes:

[0033] The electric screwdriver barcode scanning unit is used to activate the electric screwdriver barcode scanning interface when switching work orders, and to obtain and identify the electric screwdriver code.

[0034] The electric screwdriver torque verification unit is used to find the actual torque value from the electric screwdriver torque value file by scanning the electric screwdriver's code, and to find the required torque value from the electric screwdriver torque value file for the current model. It compares the actual torque value with the required torque value and issues an error alert if they do not match. The electric screwdriver barcode inspection module implements error-proof management of electric screwdriver torque values ​​during the server's production process. Screwdrivers not in the electric screwdriver file cannot be scanned to enter the system, preventing the unauthorized use of external screwdrivers.

[0035] Furthermore, the electric screwdriver barcode scanning and recording module includes:

[0036] The barcode electric screwdriver torque value information recording unit is used to input the line number, work order number, operator's employee number, machine model, screwdriver code and torque value of the current barcode electric screwdriver to generate barcode electric screwdriver torque value information record, and record the input time;

[0037] The barcode-based electric screwdriver torque value query unit is used to query matching barcode-based electric screwdriver torque value records based on user-entered criteria such as production line, work order number, operator's employee number, machine model, screwdriver code, torque value, or entry time.

[0038] Secondly, the present invention provides a method for controlling the torque value of an electric screwdriver in a server manufacturing process based on the first aspect described above, comprising the following steps:

[0039] S1. Pre-maintain the torque value file of the electric screwdriver and the torque value file of the electric screwdriver model;

[0040] S2. When the work order switching reminder condition is met, a work order switching reminder is issued based on the torque value file of the electric screwdriver for the machine model, and the number of electric screwdrivers used, torque value and the difference between the two are output for the current work order machine model and the next work order machine model.

[0041] S3. Based on the work order switching reminder, determine whether the electric screwdriver torque value file meets the required torque value and quantity of electric screwdrivers for the next work order. If it does, obtain the corresponding electric screwdriver. If it does not, modify the torque value of the corresponding electric screwdriver for use and simultaneously update the electric screwdriver torque value file.

[0042] Furthermore, the specific steps of step S1 are as follows:

[0043] S11. Establish an integrated platform for electric screwdrivers to manage and control electric screwdrivers and their torque values;

[0044] S12. Maintain the torque value file of the electric screwdriver and enter the torque value record of the electric screwdriver;

[0045] S13. Maintain the electric screwdriver torque value file for each server model, and enter the corresponding electric screwdriver torque value record. The electric screwdriver torque value record includes the record number, screwdriver type, electric screwdriver serial number, torque value, start time of use, creator, creation time, person who modified the torque value, time of modification of the torque value, and remarks.

[0046] Furthermore, the specific steps of step S2 are as follows:

[0047] S21. Determine whether the remaining number of machines in the current work order meets the work order switching reminder conditions;

[0048] If so, proceed to step S22;

[0049] If not, return to step S21;

[0050] S22. Outputs the current work order's electric screwdriver line, workstation, screwdriver type, and torque value attributes;

[0051] S23. Output the electric screwdriver line, workstation, screwdriver type, and torque value attributes for the next work order model;

[0052] S24. Compare the corresponding attributes of the current work order machine type with the next work order machine type item by item, and output whether there are any differences;

[0053] The specific steps of step S3 are as follows:

[0054] S31. Obtain the type of electric screwdriver with differences and the corresponding torque value based on the work order switching reminder;

[0055] S32. Determine whether an electric screwdriver with the corresponding torque value can be found in the electric screwdriver torque value file;

[0056] If so, proceed to step S33;

[0057] If not, proceed to step S34;

[0058] S33. Obtain the electric screwdriver with the specified torque value from the electric screwdriver management platform based on the electric screwdriver serial number, then use the electric screwdriver and end;

[0059] S34. Locate any electric screwdriver of this type in the electric screwdriver torque value file, and modify the torque value of that electric screwdriver to the desired torque value;

[0060] S35. Use the electric screwdriver with modified torque value, and simultaneously modify the corresponding electric screwdriver torque value record in the electric screwdriver torque value file, change the torque value, and record the modifier and modification time.

[0061] The beneficial effects of this invention are as follows:

[0062] The torque control system and method for electric screwdrivers in server production provided by this invention realizes the overall management of the torque value of electric screwdrivers used in server production, reduces the overall number of electric screwdrivers used, and can meet production needs without adjusting the torque value of electric screwdrivers or with only a small adjustment. Using electric screwdrivers with the corresponding adjusted torque value reduces work order switching time, facilitates the rapid traceability of work orders using electric screwdriver torque values, and greatly avoids batch material scrap caused by incorrect electric screwdriver torque values.

[0063] Furthermore, the design principle of this invention is reliable, the structure is simple, and it has a very wide range of application prospects.

[0064] Therefore, it is evident that the present invention has outstanding substantive features and significant progress compared with the prior art, and the beneficial effects of its implementation are also obvious. Attached Figure Description

[0073] The model torque value management module is used to obtain the torque value records of electric screwdrivers corresponding to the server model, generate and manage the torque value files of electric screwdrivers for the model.

[0074] The electric screwdriver usage monitoring module is used to obtain and manage records of electric screwdriver usage and related information.

[0075] The work order switching reminder module is used to output the torque value information of the current work order model, the torque value information of the next work order model, and the difference between the two based on the preset number of remaining machines when switching work orders.

[0076] The electric screwdriver barcode scanning and inspection module is used to remind the electric screwdriver to scan the barcode when switching work orders, and after scanning the electric screwdriver number, to verify whether the torque value of the electric screwdriver is consistent with the torque value of the current model.

[0077] The electric screwdriver barcode scanning and recording module is used to record and manage information such as the torque value of the barcode-scanning electric screwdriver, server model, current production line, and operator information.

[0078] The torque control system for electric screwdrivers used in server production provided by this invention enables unified management of the torque values ​​of electric screwdrivers used in server production, reduces the overall number of electric screwdrivers used, and meets production needs without adjusting the torque value of the electric screwdrivers or with only a small adjustment. Using electric screwdrivers with the correct adjusted torque value reduces work order switching time, facilitates rapid traceability of work orders using electric screwdriver torque values, and greatly avoids batch material scrapping caused by incorrect electric screwdriver torque values.

[0079] Furthermore, the design principle of this invention is reliable, the structure is simple, and it has a very wide range of application prospects.

[0080] Example 2:

[0081] like Figure 1 As shown, this invention provides a torque control system for electric screwdrivers in server manufacturing processes, comprising:

[0082] The electric screwdriver file management module is used to retrieve electric screwdriver torque value records, generate electric screwdriver torque value files, and manage them. The electric screwdriver file management module includes:

[0083] The electric screwdriver information management unit is used to manage the addition, modification, deletion, and export of electric screwdriver torque value records, and to generate electric screwdriver torque value archives.

[0084] The electric screwdriver information display unit is used to display the torque values ​​of the electric screwdriver in a list format, item by item.

[0085] The electric screwdriver information query unit is used to query and display records of electric screwdriver torque values ​​that match the user's input of screwdriver code, screwdriver type, or torque value conditions.

[0086] The electric screwdriver torque record includes the record number, screwdriver type, electric screwdriver serial number, torque value, start time of use, creator, creation time, torque value modifier, torque value modification time, and remarks. By using the electric screwdriver file, all electric screwdriver codes, torque values, torque value modifications, operations, sites, and verification personnel during the server production process can be traced, which helps improve product quality.

[0087] For example, in the interface of the electric screwdriver file management module developed under the MES system, buttons such as "query, add, modify, delete, and export" are set in the interface, and three query boxes that can be entered: "screwdriver code, screwdriver type, and torque value" are set. The maintained electric screwdriver torque value records are displayed in the table.

[0088] Enter any valid content in the "Screwdriver Code, Screwdriver Type, Torque Value" query box to query the results that match the input. You can add electric screwdriver torque value records using the "Add" function, modify existing electric screwdriver torque value records using the "Modify" function, delete electric screwdriver torque value records using the "Delete" function, and export the interface content using the "Export" function in Excel format.

[0089] In the electric screwdriver file management module interface, equipment managers can maintain the existing electric screwdrivers and their corresponding torque values ​​in the system through the electric screwdriver torque value file maintenance function. During the actual production work order switching process, for example, if the production staff needs to adjust the electric screwdriver torque value, they can use the "Modify" function to modify the electric screwdriver torque value. If the electric screwdriver malfunctions and needs to be sent for repair, a note can be made in the remarks column.

[0090] The model torque management module is used to retrieve the torque value records of electric screwdrivers corresponding to the server model, generate and manage the torque value files of electric screwdrivers for each model; the model torque management module includes:

[0091] The model torque value information management unit is used to manage the addition, modification, deletion, and export of electric screwdriver torque value records for server models, and to generate electric screwdriver torque value files for each model.

[0092] The model torque value information display unit is used to display the torque value records of the electric screwdriver corresponding to the server model in a list format one by one;

[0093] The model torque value query unit is used to query and display the torque value records of the electric screwdrivers corresponding to the server model in response to the user's input of model, electric screwdriver type and torque value conditions;

[0094] The server model's electric screwdriver torque value record includes the record number, screwdriver type, electric screwdriver serial number, torque value, start time of use, creator, creation time, person who modified the torque value, time of modification of the torque value, and remarks.

[0095] For example, in the MES system, develop the interface for the model torque value management module. In the interface, set up buttons such as "query, add, modify, delete, and export", and set up three query boxes that can be entered: "model, screwdriver type, and torque value". The torque value records of the electric screwdrivers corresponding to the server models that have been maintained are displayed in the table.

[0096] Enter any valid content in the "Model, Screwdriver Type, Torque Value" query box to search for results that match the input. You can add a new model torque value record using the "Add" function, modify an existing model torque value record using the "Modify" function, delete the model torque value record using the "Delete" function, and export the interface content using the "Export" function in Excel format.

[0097] In the machine torque value management module interface, IE personnel maintain the existing machine models and corresponding torque values ​​in the system through the machine torque value setting function. In actual production, this type of maintenance is generally a one-time maintenance and does not need to be repeated. However, when the process of the machine model changes, the maintenance content needs to be confirmed again.

[0098] The electric screwdriver usage monitoring module is used to acquire and manage records of electric screwdriver usage and registration. The electric screwdriver usage monitoring module includes:

[0099] The electric screwdriver usage and management information unit is used to generate and manage electric screwdriver usage and management records based on electric screwdriver type, torque value, usage status, and management status.

[0100] The electric screwdriver usage and management information display unit is used to display the electric screwdriver usage and management records in a list format, item by item.

[0101] The electric screwdriver usage and management information query unit is used to query and display matching electric screwdriver usage and management records in response to user input of model, screwdriver type or torque value conditions;

[0102] The refresh unit is used to update the electric screwdriver usage and management records in response to user refresh requests or preset refresh cycles.

[0103] The electric screwdriver usage and management records include the screwdriver serial number, production line, workstation, screwdriver type, torque value, usage status, whether it is on the management platform, and the person in charge. The electric screwdriver usage viewing module enables systematic management of electric screwdrivers, clearly presenting the usage status of each screwdriver. This data can be used for more accurate equipment management, analysis, spare parts replacement, and equipment maintenance.

[0104] For example, in the MES system, an interface for viewing the usage of electric screwdrivers can be developed. This interface displays the usage status of each screwdriver's serial number, including the production line, workstation, screwdriver type, torque value, whether it's on the unified management platform, and the responsible supervisor. Operators select the production line and workstation in the MES system, log in with their employee ID, scan the screwdriver's serial number and torque value to view the information. Whether it's on the unified management platform is determined through the "Electric Screwdriver Listing" function, with the responsible person provided by the production department and a fixed maintenance person for the production line load in the backend. Within this electric screwdriver usage viewing module interface, users can query relevant equipment information by "model, screwdriver type, and torque value." Clicking the "refresh" function refreshes the current interface information. Without clicking refresh, the interface automatically refreshes every 5 minutes.

[0105] The work order switching reminder module is used to output the torque value information of the current work order model, the torque value information of the next work order model, and the difference between the two, based on the preset number of remaining machines. The work order switching reminder module includes:

[0106] The reminder preset unit is used to pre-set the number of remaining machines when switching from the previous work order to the next work order. When the number of remaining machines is sufficient, the reminder interface is activated so that the production personnel can prepare the electric screwdriver.

[0107] The current work order model torque value information unit is used to display the current work order model, production line, work station, screwdriver type, and torque value information in a list format on the reminder interface;

[0108] The next work order machine type torque value information unit is used to display the next work order machine type, line, work station, screwdriver type and torque value information in a list on the reminder interface;

[0109] The difference display unit is used to compare the torque value information of the current work order model and the torque value information of the next work order model item by item and output whether there is a difference.

[0110] For example, a work order switching reminder module can be developed under the MES system. Based on product characteristics, it can determine how many machines need to be reminded in advance. The calculation logic is to retrieve the starting serial number (SN) of the work order from the MES system. The work order SNs are generally consecutive and sorted from smallest to largest. For example, if the work order switching reminder can be given 10 machines in advance, the work order switching reminder module interface will pop up when the first workstation of the 10th machine from the end scans the code. Production personnel can also view the work order switching order sequence for the day on their computers. In the work order switching reminder module, the electric screwdriver information to be used for the current work order and the next work order is automatically obtained from the machine torque value maintenance data. Furthermore, this function compares the differences. In actual production, production personnel can directly complete the advance preparation work for work order switching based on the differences displayed in the work order switching reminder.

[0111] When a work order is switched in the production personnel's operation interface, a work order switching reminder module window pops up to check the screwdriver torque value. In this interface, the employee must scan the current electric screwdriver code. The system uses the scanned electric screwdriver code to find the electric screwdriver torque value file and identify the electric screwdriver torque value data. If the found torque value data is consistent with the torque value maintained for the current model, the work order switching reminder module interface will automatically close, and the system will automatically record the screwdriver code data. If the scanned screwdriver code torque value does not match the torque value required by the system, the system will prompt an error.

[0112] The electric screwdriver barcode scanning and inspection module is used to remind users to scan the electric screwdriver's barcode when switching work orders, and to verify whether the electric screwdriver's torque value matches the current model's torque value after scanning the screwdriver's serial number. The electric screwdriver barcode scanning and inspection module includes:

[0113] The electric screwdriver barcode scanning unit is used to activate the electric screwdriver barcode scanning interface when switching work orders, and to obtain and identify the electric screwdriver code.

[0114] The electric screwdriver torque value verification unit is used to find the actual torque value from the electric screwdriver torque value file by scanning the electric screwdriver code, and to find the required torque value from the electric screwdriver torque value file of the current model. It compares the actual torque value with the required torque value and issues an error reminder when the two are inconsistent.

[0115] The electric screwdriver barcode scanning and inspection module implements error-proof management of the torque values ​​of electric screwdrivers in the server production process. Screwdrivers not in the electric screwdriver file cannot be scanned to enter the system, thus preventing the unintended use of external screwdrivers. After the torque value is adjusted, the corresponding torque value label is attached. When scanning the torque value label of the first screwdriver, if it is not the correct torque value label required by the workstation, the scanning will not pass, thus realizing the management of incorrect placement of electric screwdriver torque values.

[0116] The electric screwdriver barcode scanning and recording module is used to record and manage information such as the torque value of the scanned electric screwdriver, server model, current production line, and operator information. The electric screwdriver barcode scanning and recording module includes:

[0117] The barcode electric screwdriver torque value information recording unit is used to input the line number, work order number, operator's employee number, machine model, screwdriver code and torque value of the current barcode electric screwdriver to generate barcode electric screwdriver torque value information record, and record the input time;

[0118] The barcode electric screwdriver torque value query unit is used to query matching barcode electric screwdriver torque value records in response to user-entered conditions such as line body, work order number, operator employee number, machine model, screwdriver code, torque value, or entry time.

[0119] This module develops a barcode scanning and recording module for electric screwdrivers. The module interface includes "Query" and "Export" functions, a "Time" selection function, and six input fields: "Line Type, Work Order Number, Employee ID, Machine Model, Screwdriver Code, and Torque Value." The data source is the accumulated data from previous processes. Within the module interface, users can select a time and enter any recognizable value from these fields to query the desired information. The "Export" function exports the required data to an Excel spreadsheet. Note that the "Start" time in the "Time" function cannot be a future time; only past times can be selected.

[0122] S1. Pre-maintain the torque value file of the electric screwdriver and the torque value file of the electric screwdriver model;

[0123] S2. When the work order switching reminder condition is met, a work order switching reminder is issued based on the torque value file of the electric screwdriver for the machine model, and the number of electric screwdrivers used, torque value and the difference between the two are output for the current work order machine model and the next work order machine model.

[0124] S3. Based on the work order switching reminder, determine whether the electric screwdriver torque value file meets the required torque value and quantity of electric screwdrivers for the next work order. If it does, obtain the corresponding electric screwdriver. If it does not, modify the torque value of the corresponding electric screwdriver for use and simultaneously update the electric screwdriver torque value file.

The specific steps of step S2 are as follows:

[0132] S21. Determine whether the remaining number of machines in the current work order meets the work order switching reminder conditions;

[0133] If so, proceed to step S22;

[0134] If not, return to step S21;
