Description

Technical Field

[0001] This invention relates to the field of tooling management technology, and in particular to a method and system for managing tooling used in the production of airbags for safety systems. Background Technology

[0002] Airbags are one of the core components of a car's passive safety system. Their primary function is to form a buffer barrier by rapidly inflating when a collision occurs, absorbing and dispersing the impact energy of the occupants, and avoiding or mitigating direct and violent collisions between the occupants and hard objects inside the vehicle, thereby reducing the risk of injury or death.

[0003] Currently, the production of airbags involves multiple precision processes, including weaving, coating, molding, cutting, and sewing. These processes are interconnected, and each relies on specialized tooling (such as tension-free fabric cutting fixtures, contour folding fixtures, seam positioning clamps, and airtightness testing fixtures) for precise processing. The performance, precision, and scheduling efficiency of this tooling directly determine the processing quality and production pace of each process, playing a crucial supporting role in the final product performance of the airbag. Therefore, tooling management has become a core aspect of the airbag production process.

[0004] Regarding the aforementioned technologies, current tooling management lacks precision, relying heavily on manual application and allocation based on production experience. This makes it difficult to accurately match and locate tooling with real-time production progress and process requirements, often resulting in incorrect tooling allocation, leading to production stagnation or low efficiency. Summary of the Invention

[0005] To avoid mis-delivery of tooling due to inaccurate tooling positioning, this invention provides a method and system for managing tooling used in the production of airbags for safety systems.

[0006] In a first aspect, the present invention provides a method for managing the production tooling of airbags for safety systems, employing the following technical solution:

[0007] A method for managing the manufacturing tooling of airbags for safety systems includes:

[0008] Step 1: Obtain production progress;

[0009] Step 2: Locate the required tooling and inventory quantities based on the production schedule;

[0010] Step 3: Upon receiving a preset take-up signal, obtain the take-up quantity;

[0011] Step 4: If the prepared storage quantity is greater than or equal to the quantity to be taken, find the prepared position corresponding to the prepared tooling that meets the quantity to be taken and output it;

[0012] Step 5: If the prepared storage quantity is less than the quantity to be taken, locate the prepared position according to the prepared tooling;

[0013] Step 6: Output the prepared position and output the preset tooling shortage signal.

[0014] This also includes a method for storing pre-prepared tooling, the method comprising:

[0015] Step 40: Obtain the images to be imported into the database;

[0016] Step 41: Obtain the storage fixture and storage fixture type based on the imported image;

[0017] Step 42: Locate and output the corresponding storage area based on the type of storage tooling;

[0018] Step 43: Store the storage fixture in the storage area to obtain the pre-installed fixture;

[0019] Step 44: Obtain the tooling storage image based on the prepared tooling;

[0020] Step 45: Determine the preparation position using the tooling storage image;

[0021] Step 46: Upon receiving the pick-up signal, locate the ready position according to the prepared tooling and output it.

[0022] By adopting the above technical solution, the corresponding quantities of prepared tooling and prepared storage are obtained based on the production progress. These quantities are then compared with the quantity retrieved to determine whether to output prepared tooling or output it along with a tooling shortage signal. This avoids situations where the system cannot accurately output tooling in real time according to progress and demand, improving the reliability and efficiency of tooling management and positioning. The storage tooling and its type are obtained through the inbound image and matched with the corresponding storage area. After storage is completed, the prepared position is determined using the tooling storage image, and then retrieved using the retrieval signal. This avoids situations where tooling storage areas are chaotic and cannot be accurately located, improving the standardization and positioning accuracy of tooling storage management.

[0023] Optionally, it also includes an optimization method for storing pre-tooling, the method comprising:

[0024] Step 430: Based on the pre-prepared tooling, find the tooling function and the image in the database;

[0025] Step 431: Obtain the wear condition of the pre-prepared tooling based on the incoming images;

[0026] Step 432: Determine the main functions based on wear and tooling functionality;

[0027] Step 433: Locate and store the corresponding storage area based on the main function.

[0028] By adopting the above technical solution, the wear condition of the pre-prepared tooling is obtained through the image of the tooling entering the warehouse. Then, its main function is determined in combination with the tooling function, and then the corresponding storage area is matched for storage. This avoids the situation of unreasonable storage and poor adaptability of subsequent retrieval caused by different functional focuses and wear conditions of the tooling, and improves the targeting of tooling storage and the adaptability efficiency of subsequent retrieval.

[0029] Optionally, if the prepared storage quantity is greater than or equal to the retrieval quantity, the method for finding and outputting the prepared position corresponding to the prepared tooling that meets the retrieval quantity includes:

[0030] Step 410: Obtain the demand status;

[0031] Step 411: Locate the corresponding image to be stored in the warehouse based on the prepared tooling;

[0032] Step 412: Analyze the inbound images to obtain the corresponding inbound status;

[0033] Step 413: Sort the prepared tooling according to its warehousing status to obtain the status sorting;

[0034] Step 414: Determine the preparatory tooling group based on the status sorting and the quantity to be used;

[0035] Step 415: Obtain the bottom pad fixture and its corresponding state through the pre-tooling assembly;

[0036] Step 416: If the state of the bottom fixture is greater than the required state, obtain the prepared position based on the prepared fixture group and output it;

[0037] Step 417: If the condition of the bottom tooling is less than the required condition, output a tooling shortage signal.

[0038] By adopting the above technical solution, the pre-equipment warehousing status is analyzed by demand status and warehousing image analysis. The pre-equipment sets that meet the required quantity are sorted and filtered. The suitability is then judged by comparing the status of the bottom-level equipment with the demand status. This avoids blindly outputting the pre-equipment position and the situation where the equipment status cannot meet the demand, thus improving the accuracy of equipment management and the degree of demand adaptability.

[0039] Optionally, if the condition of the bottom-level tooling is less than the required condition, the method for outputting a tooling shortage signal includes:

[0040] Step 4170: Based on the prepared tooling group, determine the prepared tooling whose warehousing status is less than the demand status and define it as loss tooling. Define the warehousing status corresponding to the loss tooling as loss status.

[0041] Step 4171: Determine the maintenance plan based on the wear status and wear tooling;

[0042] Step 4172: Calculate the maintenance status based on the wear and tear status and maintenance plan;

[0043] Step 4173: If the maintenance status is greater than the demand status, then locate the damage location using the damage tooling.

[0044] Step 4174: Output the location of the damage and the repair plan simultaneously;

[0045] Step 4175: If the maintenance status is less than the required status, output a tooling insufficiency signal.

[0046] By adopting the above technical solution, determining the wear status and formulating a maintenance plan, and comparing the post-maintenance status with the required status, the system can output targeted signals for wear location and maintenance plan or tooling shortage. This avoids situations where wear and tooling are not handled in a timely manner and the requirements cannot be met after maintenance, thereby improving the targeting of tooling wear handling and the rationality of resource allocation.

[0047] Optionally, it also includes a method for updating the pre-installed tooling, which includes:

[0048] Step 41700: If the loss state is a preset high loss state, obtain a high loss fixture based on the loss fixture;

[0049] Step 41701: Determine the high-loss functions and replacement quantities based on the high-loss tooling;

[0050] Step 41702: Determine the tooling to replace based on the high-loss function;

[0051] Step 41703: Update the prepared tooling according to the tooling replacement and the replacement quantity.

[0052] By adopting the above technical solution, the high-loss function of the high-loss tooling is identified and the replacement quantity and tooling are determined for high-loss tooling. This allows for the updating of the backup tooling, avoiding the situation where high-loss tooling continuously occupies resources and affects subsequent use, and improving the overall integrity and reliability of the backup tooling.

[0053] Optionally, a method for updating the prepared position is also included, the method comprising:

[0054] Step 450: Count the number of tooling storage units based on the tooling storage image;

[0055] Step 451: If the number of tooling stored is not equal to the number of prepared storage, execute the preset tooling search scheme to obtain the abnormal tooling and the corresponding abnormal location;

[0056] Step 452: Replace the prepared position with the abnormal position to obtain the updated position;

[0057] Step 453: If the number of tooling storage units equals the number of units to be prepared for storage, then the tooling search will not be performed.

[0058] By adopting the above technical solution, the number of tooling stored is statistically analyzed by storing images and compared with the number of prepared storage items. In case of abnormal quantity, a search plan is executed to locate the abnormal tooling and its location, and then the prepared location is updated. This avoids the situation of incorrect tooling storage location and improves the accuracy of tooling location positioning and the real-time performance of tooling management.

[0059] Optionally, methods for executing a preset tooling search scheme to obtain the abnormal tooling and its corresponding abnormal location include:

[0060] Step 4510: Obtain the entry number based on the entry image;

[0061] Step 4511: Obtain the tooling number based on the tooling storage image;

[0062] Step 4512: Determine the exception number and the exception tooling by using the tooling number and the receiving number;

[0063] Step 4513: Locate the abnormal image by its anomaly number;

[0064] Step 4514: Obtain images of other tooling based on the pre-prepared tooling;

[0065] Step 4515: Determine the location of the anomaly based on the anomaly image and other tooling images.

[0066] By adopting the above technical solution, the abnormal number and abnormal tooling are identified by comparing the warehouse entry number with the tooling number in the tooling storage image. Then, by combining the abnormal image with other tooling images, the abnormal location is accurately located, avoiding the situation where abnormal tooling is difficult to identify and abnormal location cannot be quickly located, thus improving the efficiency and accuracy of tooling anomaly investigation.

[0067] Optionally, an optimized method for obtaining the updated position based on the anomaly location is also included, which includes:

[0068] Step 4520: Obtain other tooling based on the tooling storage image and preset tooling features;

[0069] Step 4521: If other tooling exists, determine the location of the other tooling based on the other tooling;

[0070] Step 4522: Obtain other preparatory positions corresponding to other tooling;

[0071] Step 4523: Replace other tooling positions with other pre-selected positions;

[0072] Step 4524: If no other tooling exists, the preparation position is not updated.

[0073] By adopting the above technical solution, other tooling can be identified from the stored image through tooling features, their actual positions and corresponding pre-positions can be determined and replaced, avoiding the situation where the positions of other tooling do not match the pre-positions and the updated positions are inaccurate, thus improving the targeting and accuracy of the pre-position update.

[0074] Secondly, the present invention provides a tooling management system for the production of airbags, which adopts the following technical solution:

[0075] A tooling management system for airbag production, comprising:

[0076] The acquisition module is used to acquire production progress, quantity used, demand status, and images of items entering the warehouse.

[0077] A memory for storing a program for a control method of a safety system airbag production tooling management method as described above;

[0078] The processor loads and executes programs from memory.

[0079] By adopting the above technical solution, the acquisition module accurately collects key data such as production progress and usage quantity. Combined with a memory storage management program and a processor execution program, this achieves automated data processing and logic execution throughout the entire tooling management process. This avoids the inefficiency and error-prone nature of manual data processing, ensuring the stable implementation of the aforementioned tooling management method and improving the automation level and operational reliability of airbag tooling management.

[0080] In summary, the present invention has at least one of the following beneficial technical effects:

[0081] Based on the production schedule, retrieve the prepared tooling and its corresponding quantity. When the tooling is needed, retrieve the required quantity and compare it with the quantity. Then, accurately locate the position of the tooling and output it. This avoids the situation where the tooling is incorrectly retrieved due to inaccurate tooling positioning and improves the efficiency of tooling retrieval.

[0082] By analyzing the current state of the tooling, the state after maintenance can be obtained, enabling some worn-out tooling to be restored to the required state after maintenance, ensuring the reliability and effectiveness of tooling use and improving the efficiency of tooling use.

[0083] By scanning and identifying tooling in the storage area, and analyzing whether there are any tooling storage errors, the accuracy and efficiency of tooling location are improved. Attached Figure Description

[0084] Figure 1 This is a flowchart of a method for managing the production tooling of airbags for a safety system, according to an embodiment of this application.

[0085] Figure 2 This is a scenario diagram of a method for managing the production tooling of airbags for a safety system, according to an embodiment of this application. Detailed Implementation

[0086] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0087] This invention discloses a method for managing the production tooling of airbags for safety systems.

[0088] Reference Figure 1 A method for managing the manufacturing tooling of airbags for safety systems, comprising:

[0089] Step 1: Obtain production progress.

[0090] Production progress refers to the specific process node at which the system is currently operating within the entire production process. This progress is obtained by the system connecting to the production management system, receiving feedback from workstation terminals, or scanning workpiece barcodes to acquire work order information, process completion signals, and workpiece flow data, thereby determining the current specific process node.

[0091] Step 2: Locate the required tooling and inventory quantities based on the production schedule.

[0092] Preparatory tooling refers to pre-stored tooling that matches the current production schedule and is stored in a standardized manner. The search method here is based on the fact that different production schedules require different tooling. Personnel in this field input the corresponding tooling into the system according to different schedules, and the system updates and searches for the corresponding tooling in real time based on the production schedule. The preparatory inventory quantity refers to the quantity of preparatory tooling stored. The search method here is that the system categorizes and counts the quantity of scanned tooling. Once the system determines the preparatory tooling based on the production schedule, it directly obtains the corresponding statistical quantity. For example: if the current production schedule is coating processing, requiring the processing of 500 sets of airbags, then the preparatory tooling found is a doctor blade coater, a constant temperature oven, and a tension control roller, with corresponding preparatory inventory quantities of 4 doctor blade coaters, 3 constant temperature ovens, and 6 tension control rollers, respectively.

[0093] Step 3: Upon receiving the preset take-up signal, obtain the take-up quantity.

[0094] The "use signal" refers to the signal indicating that the tooling needs to be picked up. Here, the receiving method is via an electrical signal button on the management system; the system receives the signal when the user presses the button.

[0095] The quantity to be taken refers to the number of pre-prepared tools that need to be taken. The method of acquisition here is as follows: Figure 2 The system obtains information through an operating terminal with input function in the warehouse, such as a touch screen or a digital input panel.

[0096] When a preset take-up signal is received, it indicates that the staff needs to take the corresponding pre-prepared tooling, but the quantity to be taken needs to be determined first, so the take-up quantity is obtained.

[0097] Step 4: If the prepared storage quantity is greater than or equal to the taken quantity, find the prepared position corresponding to the prepared tooling that meets the taken quantity and output it.

[0098] The ready location refers to the position of the ready-made tooling within the warehouse. The search method here is based on the system's... Figure 2 The camera device acquires real-time images of the storage area, and combines these with pre-recorded templates of various types of pre-prepared tooling appearance features. Image recognition algorithms are then used to locate the desired positions within the images. The output method here is for the system to display the obtained pre-prepared positions as shown in the image. Figure 2 The display serves as the output.

[0099] If the number of prepared tools stored is greater than or equal to the number of tools to be taken, it means that the number of prepared tools stored in the warehouse can meet the required number of tools. Therefore, find the prepared position corresponding to the prepared tool that meets the number of tools to be taken and output it.

[0100] Step 5: If the quantity to be stored is less than the quantity to be taken, locate the reserve position based on the prepared tooling.

[0101] If the number of prepared storage items is less than the number of items to be used, it means that the number of prepared tooling items stored at this time is insufficient. However, the positions corresponding to the existing prepared tooling items still need to be output. Therefore, the prepared positions are found based on the prepared tooling items.

[0102] Step 6: Output the prepared position and output the preset tooling shortage signal.

[0103] The output method for the preparatory position here is the same as described in step 4, and will not be repeated here. The insufficient tooling signal refers to a signal that the corresponding number of preparatory tools in the warehouse is insufficient. The output method here is for the system to display the insufficient tooling and the corresponding tooling type on the display screen.

[0104] This also includes a method for storing pre-prepared tooling, the method comprising:

[0105] Step 40: Obtain the images to be imported into the database.

[0106] The image being stored refers to the picture taken when the tooling is stored in the warehouse. This image is obtained by the system based on... Figure 2 The data is acquired using a scanning device, such as a camera.

[0107] Step 41: Obtain the storage fixture and storage fixture type based on the imported image.

[0108] Storage fixtures refer to fixtures whose images have been captured and stored by the camera device. Storage fixture types refer to the specific categories of the captured and stored images, categorized by function. The method used here is as follows: the system first preprocesses the stored images, then uses a target detection algorithm to identify the fixture entity from the images to obtain the storage fixture. Subsequently, the system extracts the appearance, structure, and functional component features of the fixture and compares them precisely with the features of airbag fixtures to determine the type of storage fixture.

[0109] Step 42: Locate and output the corresponding storage area based on the type of storage tooling.

[0110] A storage area refers to the range within which a storage fixture can be placed. The search method here involves having a library of storage fixtures pre-defined by professionals in the field, whose storage areas are then input into the system. Upon receiving a storage fixture, the system outputs the corresponding storage area based on the type of storage fixture.

[0111] Step 43: Store the storage fixture in the storage area to obtain the pre-installed fixture.

[0112] The method here is to scan the storage fixture to obtain the image, divide the area, store it in the storage area, and then define the storage fixture as a pre-installed fixture.

[0113] Step 44: Obtain the tooling storage image based on the prepared tooling.

[0114] Tooling storage image refers to the image of the tooling being stored in the storage area. The method for obtaining this image is as described in step 4. Figure 2 The video was captured by the camera device.

[0115] Step 45: Determine the preparation position using the tooling storage image.

[0116] The method here is as follows: the system uses an image recognition algorithm to locate the storage fixture within the corresponding area of ​​the image; combined with the pixel coordinates of the fixture in the image and its relative position with the area boundary / surrounding reference objects, the system matches the area subdivision identifier and finally determines the specific placement position of the fixture within the storage area.

[0117] Step 46: Upon receiving the pick-up signal, locate the ready position according to the prepared tooling and output it.

[0118] When a pick-up signal is received, it indicates that the tooling needs to be picked up. Therefore, the ready position is located according to the prepared tooling and output.

[0119] This also includes an optimization method for storage pre-tooling, which includes:

[0120] Step 430: Based on the pre-prepared tooling, find the tooling function and the image to be added to the database.

[0121] Tooling function refers to the effectiveness of pre-installed tooling during the production of airbags. The search method here involves different pre-installed toolings corresponding to different functions, determined by professionals in the field based on the steps each tooling performs in the production process and the resulting effectiveness, which are then input into the system. The method for searching for stored images involves the system taking an image of each pre-installed tooling upon storage and associating it with a unique tooling identifier. When the system searches for a pre-installed tooling based on the production progress, it retrieves the stored image using that tooling's unique identifier.

[0122] Step 431: Obtain the wear condition of the pre-prepared tooling based on the image of the incoming equipment.

[0123] Wear and tear refers to the appearance and functional damage caused by friction, stress, aging, etc., during past use of the pre-prepared tooling. This is achieved by the system extracting detailed features from retrieved images from the database, comparing them with a brand-new standard image of the tooling type, and determining the degree of wear by identifying features such as surface damage, component integrity, and dimensional deviations.

[0124] Step 432: Determine the main functions based on wear and tooling functionality.

[0125] The primary function refers to the single, core function of the tooling during the production process. This is determined by the system verifying the tooling's performance in each production step based on wear and tear, thus identifying the most frequently used core function.

[0126] Step 433: Locate and store the corresponding storage area based on the main function.

[0127] Tooling with multiple functions is stored in designated storage areas according to its primary functions.

[0128] Among them, if the prepared storage quantity is greater than or equal to the retrieval quantity, the method for finding and outputting the prepared position corresponding to the prepared tooling that meets the retrieval quantity includes:

[0129] Step 410: Obtain the demand status.

[0130] Demand status refers to the minimum qualified state required for pre-tooling to enable workers to successfully complete the corresponding production workload. This is obtained by the user through... Figure 2 The input is obtained from the control terminal.

[0131] Step 411: Locate the corresponding image to be imported based on the pre-prepared tooling.

[0132] The search method here is the same as that described in step 430, so it will not be repeated here.

[0133] Step 412: Analyze the images to obtain the corresponding entry status.

[0134] The warehousing status refers to the actual wear and tear condition of the tooling upon completion of its warehousing process. This is achieved by the system performing refined feature extraction on the warehousing image, identifying details such as surface damage, missing components, dimensional deviations, and functional structural wear. Combined with standard status parameters for this type of tooling, the system comprehensively assesses the wear and tear condition of the tooling before warehousing as its warehousing status.

[0135] Step 413: Sort the prepared tooling according to its entry status to obtain the status sorting.

[0136] Status sorting refers to the sorting of various states of the tooling. Here, it is obtained by judging the inbound status and then arranging the states from best to worst.

[0137] Step 414: Determine the preparatory tooling group based on the status sorting and the quantity to be used.

[0138] A pre-prepared tooling set refers to a combination of pre-prepared tools. The method for determining this is that the system extracts pre-prepared tools sequentially based on their status until the required quantity is reached.

[0139] Step 415: Obtain the bottom pad fixture and its corresponding state through the pre-tooling assembly.

[0140] The "bottom-line tooling" refers to the tooling in the worst-condition state upon arrival in the tooling group. The "bottom-line tooling status" refers to the loss status corresponding to the tooling in the worst-condition state upon arrival. This is obtained by the system selecting the tooling in the worst-condition group as the bottom-line tooling, and simultaneously extracting the corresponding loss information for that tooling and treating it as the bottom-line tooling status.

[0141] Step 416: If the state of the bottom fixture is greater than the required state, obtain the preparation position based on the preparation fixture group and output it.

[0142] The acquisition and output methods here are the same as those described in step 4, and will not be repeated here.

[0143] If the status of the bottom-level tooling is greater than the required status, it means that the tooling in the preparatory tooling group can complete the corresponding workload and will not be damaged in the middle. Therefore, the preparatory position is obtained and output according to the preparatory tooling group.

[0144] Step 417: If the condition of the bottom tooling is less than the required condition, output a tooling shortage signal.

[0145] If the condition of the bottom-level tooling is less than the required condition, it indicates that some tooling may be damaged during the production process, which will affect the production schedule. Therefore, a tooling shortage signal is output.

[0146] Among them, the methods for outputting a tooling shortage signal when the condition of the bottom-level tooling is less than that of the required condition include:

[0147] Step 4170: Based on the prepared tooling group, determine the prepared tooling whose warehousing status is less than the demand status and define it as loss tooling. Define the warehousing status corresponding to the loss tooling as loss status.

[0148] Loss-prone tooling refers to pre-installed tooling in the pre-installed tooling group whose warehousing status does not meet the required status. Here, the system compares the status of each tool in the pre-installed tooling group sequentially with the required status. Tooling that cannot meet the required status is considered loss-prone tooling, and its corresponding warehousing status is considered loss-prone.

[0149] Step 4171: Determine the maintenance plan based on the wear status and wear tooling.

[0150] A maintenance plan refers to a targeted repair plan developed to restore a worn tool to a certain condition, based on its specific wear and tear. For example, if the positioning groove of a folding positioning template is slightly deformed, the maintenance plan would be to use a precision straightening tool to straighten the deformed part of the positioning groove.

[0151] Step 4172: Calculate the maintenance status based on the wear status and maintenance plan.

[0152] Maintenance status refers to the state of worn tooling after it has been repaired according to the maintenance plan. The calculation method here is as follows: the system first quantifies the core parameters of the current wear status of the tooling, matches the wear improvement effect corresponding to each repair measure in the maintenance plan, combines the maintenance target and superimposes all improvement effects, and calculates the core parameters, appearance and functional status of the tooling after maintenance, thereby determining the maintenance status.

[0153] Step 4173: If the maintenance status is greater than the demand status, then locate the damage location using the damage tooling.

[0154] The location of the damaged tooling refers to its specific storage location within the warehouse storage area. The method for finding this location is the same as that described in step 4, and will not be repeated here.

[0155] If the maintenance status is greater than the demand status, it means that the tooling can meet the demand status after maintenance. Therefore, the location of the loss can be found by using the worn tooling.

[0156] Step 4174: Output the location of the damage and the repair plan simultaneously.

[0157] The output method here is the same as that described in step 4, except that the maintenance plan is output along with the output position, which will not be elaborated here.

[0158] Step 4175: If the maintenance status is less than the required status, output a tooling insufficiency signal.

[0159] If the maintenance status is less than the demand status, it means that even if the tooling is repaired, it cannot meet the demand status and cannot complete the corresponding workload. Therefore, a tooling shortage signal is output.

[0160] This also includes a method for updating pre-tooling, which includes:

[0161] Step 41700: If the loss state is the preset high loss state, obtain the high loss tooling based on the loss tooling.

[0162] High wear and tear refers to a critical wear and tear state in which tooling is close to being scrapped and will soon be unusable.

[0163] High-loss tooling refers to tooling that is nearing the point of being scrapped and will soon be unusable. The system first retrieves the high-loss condition criteria, then compares the loss status of each piece of tooling with the criteria, and filters out tooling that meets the high-loss condition criteria.

[0164] If the wear status is the preset high wear status, it means that the wear of the tooling is close to being scrapped and needs to be replaced with a new tooling. Therefore, a high wear tooling is obtained based on the wear tooling.

[0165] Step 41701: Determine the high-loss functions and replacement quantities based on the high-loss tooling.

[0166] High-loss functions refer to the core functions that high-loss tooling cannot perform normally during the airbag production process. This is determined by the system retrieving the core functions of the airbag production process adapted to the high-loss tooling as the high-loss function. Replacement quantity refers to the number of high-loss tooling units that need to be replaced. This is determined by the system directly counting the total number of current high-loss tooling units.

[0167] Step 41702: Determine the tooling to be replaced based on the high-loss function.

[0168] Replacement tooling refers to replacing the high-wear tooling with new tooling. This is determined by the system searching the network for the latest, qualified tooling with high-wear functionality.

[0169] Step 41703: Update the prepared tooling according to the tooling replacement and the replacement quantity.

[0170] The update method here is to replace the high-wear tooling with a replacement tooling as a backup tooling.

[0171] This also includes a method for updating the prepared position, which includes:

[0172] Step 450: Count the number of tooling storage based on the tooling storage image.

[0173] The number of tools stored refers to the number of tools present in the tooling storage image. This is calculated by the system performing image recognition on the tooling storage image and automatically counting the total number of tools presented in the image.

[0174] Step 451: If the number of tooling stored is not equal to the number of prepared storage, execute the preset tooling search scheme to obtain the abnormal tooling and the corresponding abnormal location.

[0175] Finding tooling solutions refers to the standard operating procedure for finding abnormal tooling. Abnormal tooling refers to tooling that is not located in the storage area corresponding to its specified tooling. Abnormal location refers to the position of the abnormal tooling. In this case, different storage areas correspond to different tooling characteristic information. Personnel in the field determine the tooling characteristics of the storage area and input them into the system. The system then identifies and compares the tooling storage images, filtering out tooling that does not match the tooling characteristics of its corresponding area as abnormal tooling, and designating the position of that tooling as an abnormal location.

[0176] If the number of tooling stored is not equal to the number of pre-stored tools, it means that there are other toolings in this area or that some toolings have been placed in other areas. Therefore, the preset tooling search scheme is executed to obtain the abnormal toolings and their corresponding abnormal locations.

[0177] Step 452: Replace the prepared position with the abnormal position to obtain the updated position.

[0178] The updated location refers to the exact location of the faulty tool after the update. This is obtained by replacing the original reserve location of the tool with the faulty location as the reserve location.

[0179] Step 453: If the number of tooling storage units equals the number of units to be prepared for storage, then the tooling search will not be performed.

[0180] If the number of tooling stored is equal to the number of pre-stored tools, it means that the corresponding tooling is placed in the area and there is no misplacement. Therefore, the tooling search plan is not executed.

[0181] The method for executing a preset tooling search scheme to obtain the abnormal tooling and its corresponding abnormal location includes:

[0182] Step 4510: Obtain the entry number based on the entry image.

[0183] The warehouse entry number refers to the unique identification number assigned to each piece of tooling when it enters the warehouse. This number is obtained by the system automatically reading the unique identification number corresponding to the tooling from the image of the incoming tooling through barcode recognition or text extraction.

[0184] Step 4511: Obtain the tooling number based on the tooling storage image.

[0185] The tooling number refers to the unique identifier for each tooling unit in the tooling storage image. This identifier is obtained by the system performing feature recognition on each tooling unit within the tooling storage image, extracting the unique identifier for each tooling unit.

[0186] Step 4512: Determine the exception number and the exception tooling by using the tooling number and the warehouse entry number.

[0187] An anomaly number refers to a tooling number extracted from the tooling storage image that does not match the corresponding inbound number for that storage area. The method for determining this is as follows: the system retrieves the inbound number list corresponding to the current storage area, then compares all tooling numbers extracted from the tooling storage image with this list one by one, filtering out numbers that are not in the list or that should be in the list but are not present.

[0188] Step 4513: Locate the abnormal image by abnormal number.

[0189] An abnormal image refers to the image of the tooling corresponding to the abnormal number upon entering the warehouse. The search method here is the same as that described in step 430, and will not be repeated here.

[0190] Step 4514: Obtain images of other tooling based on the pre-prepared tooling.

[0191] Other tooling images refer to images corresponding to other storage areas. The method for obtaining these images is the same as that described in step 44, and will not be repeated here.

[0192] Step 4515: Determine the location of the anomaly based on the anomaly image and other tooling images.

[0193] The method used here is to compare the abnormal image with other tooling images to accurately locate the specific position of the abnormal tooling within the corresponding storage area as the abnormal location.

[0194] This also includes an optimized method for obtaining updated positions based on abnormal locations, which includes:

[0195] Step 4520: Obtain other tooling based on the tooling storage image and preset tooling features.

[0196] Tooling features refer to the unique characteristics used to distinguish and identify tooling. Other tooling refers to tooling that does not belong to the storage area corresponding to the tooling storage image. The acquisition method here is that the system performs a full-image scan and identification of the tooling storage image based on preset tooling features, and filters out tooling that does not match the tooling features that should be stored in the current storage area and does not belong to that area.

[0197] Step 4521: If other tooling exists, determine the location of other tooling based on the other tooling.

[0198] Other tooling locations refer to the specific locations of other tools within this storage area. This is determined by the system performing pixel-level positioning and coordinate calibration on the tooling storage image, and then combining this with the feature recognition results of other tools to pinpoint their specific pixel coordinates within the current storage area image.

[0199] If other tooling exists, it means that there is tooling in the storage area that does not belong to this area. Therefore, the location of other tooling is determined based on other tooling.

[0200] Step 4522: Obtain other preparatory positions corresponding to other tooling.

[0201] Other preparatory locations refer to the original locations of other tooling within their corresponding storage areas. This is obtained by the system using the tooling's number or characteristic information to retrieve its storage location recorded when it was put into storage.

[0202] Step 4523: Replace other tooling positions with other prepared positions.

[0203] The replacement method here is the same as that described in step 452, so it will not be repeated here.

[0204] Step 4524: If no other tooling exists, the preparation position is not updated.

[0205] If no other tooling exists, it means that the area contains the corresponding tooling, so the preparation position is not updated.
