Description

Technical Field

[0001] The present invention relates to the technical field of warehousing management, and more particularly, to a method, a system and a storage medium for the warehousing of materials. Background Art

[0002] As an important technology in modern warehousing management, the automated stereoscopic warehouse is designed based on a three-dimensional storage structure and automated equipment, aiming to achieve efficient storage and management of items. With the development of information technology and automated equipment, this technology has been widely applied to the warehousing management of various industries, demonstrating superior advantages such as space saving, efficiency improvement, error reduction, and goods protection. Although the automated stereoscopic warehouse technology provides a solid foundation for the warehousing management of many industries, there are still many deficiencies in specific fields, especially in the machining industry, and particularly in the special machining industry.

[0003] In the conventional design of an automated stereoscopic warehouse, a variety of equipment is usually configured, such as a pallet jack elevator, a pallet beam rack, a roadway stacker, a chain conveyor, a roller conveyor line, a lifting transfer machine, and a fixed barcode reader, etc. These devices can achieve basic automated inbound and outbound operations and meet the warehousing needs of general goods. However, this setup has limitations in the detection part of the incoming materials, with problems such as incorrect identification of materials and poor information compliance, which in turn affect production efficiency and cost control. Summary of the Invention

[0004] The problem solved by the present invention is how to optimize the incoming process of materials to improve production efficiency and achieve cost control.

[0005] To solve the above problems, the present invention provides a method, a system and a storage medium for the warehousing of materials.

[0006] In a first aspect, the present invention provides a method for the warehousing of materials, which is applied to a material intelligent management system. The material intelligent management system includes a visual inspection system and a measurement system; the method for the warehousing of materials includes:

[0007] When the material to be warehoused reaches the warehousing entrance, defect detection is performed on the material according to the preset standard by the visual inspection system;

[0008] Grouping operation is performed on the materials that meet the preset standard to obtain the grouped materials after binding;

[0009] Based on the measurement system, an inbound judgment is made on the grouped materials after binding according to the preset inbound standard. If the preset inbound standard is met, the storage location is automatically allocated according to the material information of the grouped materials after binding.

[0010] Optionally, if the preset warehousing standard is met, the storage location is automatically allocated according to the material information of the grouped palletized materials after binding, including:

[0011] Inspect the grouped palletized materials after binding to obtain an inspection result, where the inspection result includes dimension information and weighing information;

[0012] When both the dimension information and the weighing information meet the preset warehousing standard, read the corresponding material information and automatically allocate the storage location based on the material information;

[0013] When any one of the dimension information or the weighing information does not meet the preset warehousing standard, return the grouped palletized materials after binding to the abnormal processing port for abnormal detection.

[0014] Optionally, the visual inspection system includes a preset visual inspection model, and the materials are defect-detected according to the visual inspection system according to a preset standard; the operation of palletizing the materials that meet the preset standard to obtain the grouped palletized materials after binding includes:

[0015] Obtain the image data of the materials;

[0016] Based on the image data, inspect the materials according to the preset visual inspection model to obtain a visual inspection result;

[0017] When the visual inspection result meets the preset standard, bind the materials to the corresponding pallet to form the grouped palletized materials after binding;

[0018] When the visual inspection result does not meet the preset standard, return the materials to the abnormal processing port for abnormal detection.

[0019] Optionally, the method for warehousing the materials further includes:

[0020] Obtain the actual waste data during the processing of the materials;

[0021] Analyze the actual waste data and the corresponding weighing information to obtain an analysis result.

[0022] Optionally, the analyzing the actual waste data and the corresponding weighing information to obtain an analysis result includes:

[0023] Obtain ratio data based on the actual waste data and the corresponding weighing information, and judge the ratio data according to a preset threshold;

[0024] When the ratio data exceeds the preset threshold, mark and feedback the materials; and evaluate the waste situation of the materials at different time periods through time series analysis.

[0025] Optionally, the method for storing the material further includes:

[0026] Before the material reaches the storage inlet, create an initial storage document based on the information of the material;

[0027] Wherein, the initial storage document includes the main document information and the document detail list. The main document information at least includes the document number, the storage date, and the supplier information; the document detail list includes the category code, the batch sequence number, the process number, and the quantity data of the material.

[0028] Optionally, the step of binding the material to the corresponding pallet further includes:

[0029] Perform a palletizing operation on the material and at least one pallet to form the palletized material after binding;

[0030] Based on the information of the palletized material after binding, automatically associate the initial storage document and update the initial storage document so that it includes the material information of the palletized material after binding. Wherein, the material information is unique to ensure that each palletized material after binding is uniquely identified in the material intelligent management system.

[0031] Optionally, the method for storing the material further includes:

[0032] When the palletized material after binding is out of storage, transport the palletized material after binding as a whole to the designated target location and perform an unbinding operation on the palletized material after binding;

[0033] Construct an outbound document according to the received outbound request and sort the outbound document according to the preset priority

[0034] In a second aspect, the present invention provides a material storage system, including a memory and a processor; the memory is used to store a computer program; the processor is used to implement the material storage method as described in the first aspect when executing the computer program

[0035] In a third aspect, the present invention provides a computer-readable storage medium, characterized in that a computer program is stored on the storage medium, and when the computer program is executed by a processor, the material storage method as described in the first aspect is implemented.

[0036] The beneficial effects of the material storage method, system and storage medium of the present invention are: This method is applied to the material intelligent management system, aiming to improve the efficiency and accuracy of the material storage process.

[0037] When the material transportation arrives at the warehouse entrance, start the defect detection and warehousing judgment program. Based on the vision detection system, actively conduct defect detection on the materials to be warehoused according to preset standards (such as surface, color, shape, etc.). The purpose of this step is to screen out materials that meet the quality standards, improve the warehousing efficiency, and reduce the risk of later returns or rework.

[0038] For the materials that pass the inspection, perform the palletizing operation to form the palletized materials after binding. This process involves combining multiple single-piece materials with the corresponding pallets for subsequent management and handling.

[0039] Use the measurement system to make a warehousing judgment on the palletized materials after binding, and decide whether they can be officially warehoused according to the preset warehousing standards (such as weight, volume, etc.).

[0040] If the warehousing judgment is qualified, the material information related to the palletized materials will be automatically read, and intelligent allocation of storage locations will be carried out based on this information. This process reduces manual intervention and improves the intelligent level of material management.

[0041] The above warehousing process significantly reduces the time required for material warehousing through an automated detection and judgment process, improving the overall operation efficiency. At the same time, using vision and measurement systems instead of manual inspections reduces the dependence on human resources, lowers the related labor costs, and reduces the possibility of human errors. For example, using the vision detection system to take pictures and perform visual recognition on the incoming blank materials, the captured images can be identified and associated with the unique code of the product. This process helps to trace the appearance defects of the blank materials. Especially when suppliers provide precision precious metal machining services to customers, it can effectively support the review and traceability of the appearance of incoming blank materials. Through the vision detection system, the unique code on the surface of the incoming products can be automatically identified, thus accurately verifying the material palletizing work of personnel during the warehousing stage and improving the accuracy of raw material information. At the same time, the vision detection system has an intelligent judgment function and can detect the appearance quality of products. Once an error is found, the relevant materials will be returned to the abnormal detection station, and the staff will be prompted to handle it. The measurement system can include a weighing unit. By using a high-precision weighing unit to weigh the incoming blank materials and effectively review the weight information with the metal chips collected and statistically generated during the processing, it can also analyze and evaluate them, thereby intuitively reflecting the material loss situation.

[0042] By using preset standards for defect detection, it is ensured that the materials entering the warehouse meet the quality standards, controlling the material quality from the source and reducing subsequent problems. Finally, through intelligent storage location allocation, the warehouse space can be utilized more reasonably, enhancing the flexibility and response speed of inventory management.

[0043] Generally speaking, by introducing an intelligent management system, this material warehousing method not only improves the efficiency and accuracy of material management, but also promotes the informatization and automation processes of enterprises, providing an effective solution for the current rapidly developing logistics and warehousing industries.

[0047] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings. Although some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments described herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present invention. It should be understood that the drawings and embodiments of the present invention are only for exemplary purposes and are not used to limit the protection scope of the present invention.

[0048] It should be understood that the various steps recorded in the method embodiments of the present invention can be executed in different orders and / or executed in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present invention is not limited in this regard.

[0049] As used herein, the term "including" and its variations are open-ended, that is, "including but not limited to"; the term "based on" is "at least partially based on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments"; the term "optionally" means "optional embodiment". The relevant definitions of other terms will be given in the following description. It should be noted that the concepts such as "first" and "second" mentioned in the present invention are only used to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependent relationships.

[0050] It should be noted that the modifications of "one" and "multiple" mentioned in the present invention are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly specified in the context, it should be understood as "one or more".

[0051] The names of the messages or information exchanged between multiple devices in the embodiments of the present invention are only for illustrative purposes and are not used to limit the scope of these messages or information.

[0052] In the related automated stereoscopic warehouse technology, rope breakage and overload protection devices for the stacking crane lifting mechanism are commonly used to ensure that the goods stored in the warehouse do not exceed the rated setting value of the shelf. This measure can ensure the safe operation of the equipment to a certain extent, but there are still limitations in terms of operation accuracy and flexibility in handling special materials. Especially when dealing with precious metals and other special materials, the standardized protection measures are difficult to meet their complex production requirements.

[0053] In addition, the special processing industry has particularly strict requirements for the management of raw materials, and it is necessary to comprehensively track and record the status of raw materials from the beginning of their entry into the factory. This record should not only include the unique code of the product (material), but also cover the appearance status of the product, so as to enable complete traceability management. However, the management system of the existing automated stereoscopic warehouse fails to provide such comprehensive tracking and recording capabilities, which limits the intelligent development of the machining industry.

[0054] Although the automated stereoscopic warehouse technology shows significant advantages in general warehouse management, it still seems inadequate in meeting the complex requirements of the machining industry, especially the special machining industry. Therefore, in response to the special needs of the machining industry, more refined and intelligent solutions must be developed to achieve comprehensive, accurate, and efficient management of materials, enabling them to adapt to various requirements of the production process.

[0055] In view of the problems existing in the above related technologies, this embodiment provides a method and device for material warehousing.

[0056] As Figure 1 shown, a method for material warehousing provided by an embodiment of the present invention is applied to a material intelligent management system, and the material intelligent management system includes a vision detection system and a measurement system; the method for material warehousing includes;

[0057] Step S100, when the material to be warehoused reaches the warehousing port, defect detection is performed on the material according to the vision detection system according to a preset standard.

[0058] Specifically, the intelligent material management system also includes PDA (Personal Digital Assistant, a portable computer device usually with a touch screen interface for data input, processing, and storage), ERP (Enterprise Resource Planning, an integrated management information system for managing a company's internal and external resources, including production, supply chain, finance, human resources, etc.), WMS (Warehouse Management System, a software system for managing warehouses and inventory operations, including receiving, storing, picking, shipping, and inventory control, etc.), MES (Manufacturing Execution System, an information system for monitoring and controlling the factory production process to ensure the efficiency and quality of the production process), and WCS (Warehouse Control System, a system for automating and optimizing the operations of warehouses and distribution centers).

[0059] When the material transportation arrives at the warehouse entrance, it is automatically identified and ready for inbound processing. This step marks the start of the inbound process and has important significance in terms of time nodes.

[0060] First, start the integrated vision inspection system, which consists of multiple high-definition cameras or optical sensors and can capture the image data of the materials to be warehoused in real time. That is, the vision inspection system takes pictures of the materials and generates two-dimensional or three-dimensional image data of the materials. Subsequently, the vision inspection system will preprocess the captured images, such as image sharpening, noise reduction, etc., to improve the accuracy of subsequent analysis.

[0061] Based on preset standards (such as size, shape, color, surface integrity, etc.), the materials will be inspected using image processing algorithms and machine learning models. For example, the key features of the materials can be extracted from the images. By comparing with the preset standards, potential appearance defects, such as scratches, dents, color differences, dirt, etc., can be identified. After the inspection is completed, the inspection results will be output. If the materials meet the preset standards, they will enter the next step of the inbound process; if defects are detected, the system will mark the materials as abnormal and send them back to the abnormal processing port for further processing or review.

[0062] Through automated defect detection, ensure that the quality of the incoming materials meets the preset standards, reduce the entry of unqualified materials, and lower the quality risks in the later stage. Moreover, the automated detection process significantly reduces the errors caused by manual intervention. Especially when dealing with complex shapes or surface features, the detection results of the system are more consistent and accurate. And the vision inspection system can process the inspection of a large number of materials in real time at a high speed, significantly improving the efficiency compared with traditional manual inspection and speeding up the warehousing process.

[0063] Moreover, the detection results can be immediately feedback, facilitating the management to take measures promptly. If defective materials are found, they can be quickly marked and removed, avoiding subsequent quality problems. In addition, all detection data can be recorded for future traceability and analysis. At the same time, by ensuring the quality of the incoming materials, the inventory turnover rate can be optimized, reducing unnecessary costs such as material rework or return due to quality problems, and improving the overall management efficiency.

[0064] Step S200, perform a palletizing operation on the materials that meet the preset standards to obtain the palletized materials after binding.

[0065] Specifically, according to the defect detection of the materials in step S100, select the materials that meet the preset standards. Once the qualified materials are selected, the palletizing operation will be started. Palletizing can integrate the same type or different types or different quantities of materials together for subsequent processing, packaging or distribution.

[0066] Automatically formulate a palletizing strategy according to the production plan and specific operation requirements. This may involve the type, quantity, arrangement order and combination method of the materials to ensure modularization and optimized workflow. The actual combination process of the materials usually includes transporting the qualified materials to the palletizing area through an automatic transportation system (such as a conveyor belt, AGV, etc.), and then using automatic equipment (such as a robotic arm or picking robot) to pick up and place the materials according to the preset palletizing strategy to complete the combination with other materials to form palletized materials. And the pallet has a unique code, and through the palletizing process, the pallet code is also associated with the material code.

[0067] After palletizing, information records related to the palletized materials will be generated, including the material type, quantity, combination method and its unique identification code. These information will be stored in the system database for convenient subsequent tracking and management. At the same time, after palletizing, an optional quality inspection step can ensure the integrity and compliance of the palletized materials after combination, further ensuring the smooth progress of subsequent processing.

[0068] The handling efficiency of materials has been significantly improved through automated palletizing operations, reducing time consumption and human errors compared to manual operations, and ensuring the efficient operation of the production line. By rationalizing the palletizing of materials, more efficient inventory turnover can be achieved, reducing the occupied space and costs of material storage, while facilitating a quick response to market demands. Moreover, the WCS can dynamically adjust the palletizing strategy according to real-time demands, making production more flexible and adaptable to diverse product types and market changes.

[0069] Step S300: According to the measurement system, perform an inbound judgment on the palletized materials after binding based on a preset inbound standard. If the preset inbound standard is met, automatically allocate storage locations according to the material information of the palletized materials after binding.

[0070] Specifically, after completing the palletizing operation, an inbound judgment will be made on the palletized materials after binding based on the measurement system. The purpose of this step is to confirm whether these materials meet the preset inbound standards.

[0071] The measurement system (such as a laser rangefinder, a weighing sensor, or a vision recognition system) will perform real-time detection on the palletized materials and evaluate whether their characteristics (such as size, weight, quantity, and overall integrity) meet the preset inbound standards. These standards can include: size requirements of the materials. weight limits of the materials. integrity of the materials and identification of non-conforming products. By comparing the measurement data with the preset inbound standards, a judgment is made: if the inbound standards are met, the process will continue to the storage location allocation process. If the inbound standards are not met, the palletized materials will be marked as non-conforming and may indicate manual recheck or processing (such as rework or return).

[0072] For the palletized materials that meet the inbound standards, storage locations will be automatically allocated according to their material information (including material types, attributes, demand frequencies, etc.). This process includes: selecting a suitable storage location: selecting a suitable location from the preset storage locations, considering factors such as the availability of the storage location, the characteristics of the materials, and improving the picking efficiency. And by creating and recording the inbound task, notifying the relevant material conveying system (such as an AGV or a conveyor belt) to move the palletized materials to the designated storage location. All inbound information (such as inbound time, material status, storage location number, etc.) will be automatically recorded in the system database for subsequent tracking, management, and report generation.

[0073] Based on the automatic evaluation of the system, it can effectively reduce the subjectivity and errors in manual evaluation, ensuring the accuracy and consistency of the inbound process. And the automated storage location allocation can be adjusted in real time according to the characteristics and demands of the materials, making full use of the warehouse space, improving inventory management, and enhancing the material handling efficiency. Moreover, through the preset inbound standards and real-time measurement, materials that do not meet the standards can be detected at the earliest stage, reducing subsequent losses caused by damage or non-conformance.

[0074] In summary, the automatic warehousing judgment and storage location allocation based on the measurement system not only improve the working efficiency and accuracy of the warehouse, but also effectively optimize the material management process, enhance the overall supply chain management ability of the enterprise, and provide strong support for meeting market demands and customer services.

[0075] In this embodiment, the method is applied to the intelligent material management system, aiming to improve the efficiency and accuracy of the material warehousing process.

[0076] When the material transportation arrives at the warehousing entrance, start the defect detection and warehousing judgment program. Based on the vision detection system, actively conduct defect detection on the materials to be warehoused according to preset standards (such as surface, color, shape, etc.). The purpose of this step is to screen out the materials that meet the quality standards, improve the warehousing efficiency and reduce the risk of later returns or rework.

[0077] For the materials that pass the inspection, implement the palletizing operation to form the palletized materials after binding. This process involves combining multiple single-piece materials with the corresponding pallets for subsequent management and handling.

[0078] Use the measurement system to conduct warehousing judgment on the palletized materials after binding, and decide whether they can be officially warehoused according to the preset warehousing standards (such as weight, volume, etc.).

[0079] If the warehousing judgment is qualified, the material information related to the palletized materials will be automatically read, and intelligent storage location allocation will be carried out based on this information. This process reduces manual intervention and improves the intelligent level of material management.

[0080] The above-mentioned warehousing process significantly reduces the time required for material warehousing and improves the overall operation efficiency through an automated detection and judgment process. At the same time, a vision and measurement system is used to replace manual inspection, reducing the dependence on human resources, lowering the related labor costs, and reducing the possibility of human errors. For example, a vision detection system is used to take pictures and perform visual recognition on the incoming rough materials, and the captured images can be identified and associated with the unique code of the product. This process helps to trace the appearance defects of the rough materials. Especially when suppliers provide precision precious metal machining services to customers, it can effectively support the review and traceability of the appearance of the incoming rough materials. The unique code on the surface of the incoming products can be automatically identified through the vision detection system, thus accurately verifying the material grouping work of personnel during the warehousing stage and improving the accuracy of raw material information. At the same time, the vision detection system has an intelligent judgment function and can detect the appearance quality of products. Once an error is found, the relevant materials will be returned to the abnormal detection station and prompt the staff to handle it. The measurement system can include a weighing unit. By using a high-precision weighing unit to weigh the incoming rough materials and effectively review the weight information with the metal chips collected and counted during the processing, it can also analyze and evaluate them, and then intuitively reflect the material loss situation.

[0081] By using preset standards for defect detection, it is ensured that the materials entering the warehouse meet the quality standards, controlling the material quality from the source and reducing subsequent problems. Finally, through intelligent storage location allocation, the warehouse space can be utilized more reasonably, enhancing the flexibility and response speed of inventory management.

[0082] Generally speaking, through the introduction of an intelligent management system, this material warehousing method not only improves the efficiency and accuracy of material management, but also promotes the informatization and automation process of the enterprise, providing an effective solution for the current rapidly developing logistics and warehousing industries.

[0083] Optionally, if the preset warehousing standard is met, automatically performing storage location allocation according to the material information of the grouped materials after binding includes:

[0084] Detecting the grouped materials after binding to obtain a detection result, where the detection result includes dimension information and weighing information;

[0085] When both the dimension information and the weighing information meet the preset warehousing standard, reading the corresponding material information and automatically performing storage location allocation based on the material information;

[0086] When any one of the dimension information or the weighing information does not meet the preset warehousing standard, the grouped materials after binding are sent to the abnormal processing port for abnormal detection.

[0087] Specifically, first, the grouped pallet materials after binding are comprehensively detected by a measurement system. This process mainly involves two aspects of detection: Dimension detection: Use sensors (such as laser rangefinders) to obtain the dimension information of the grouped pallet materials to ensure that they meet specific size and shape requirements. For the length, width, and height data in the dimension information, they are the overall length, width, and height data of the grouped pallet materials. Weighing detection: Equipment such as electronic scales can be used to measure the weight of the materials, or a weighing module can also be installed at the bottom of the legs of the weighing conveyor line (meeting Class I accuracy, with an error of ±0.05 kg) to ensure that it is within the preset weight range. After the detection is completed, the detection results will be summarized, including the obtained dimension information and weighing information.

[0088] Based on the detection results, it is judged whether the preset warehousing standards are met: When both the dimension information and the weighing information meet the preset warehousing standards (for example, the dimension range does not exceed 90% of the dimensions of the automated storage and retrieval system), the warehouse location allocation process will continue. When any one does not meet the preset warehousing standards: The exception handling mechanism will be triggered, and the grouped pallet materials will be sent to the designated exception handling port for subsequent inspection and processing. And information prompt functions such as audible and visual alarms can be equipped.

[0089] If the detection results find that the dimensions or weighing do not meet the standards, the system will send these materials to the exception handling port for more in-depth manual or automatic detection: Possible steps include manual recheck, remeasurement, and judging whether these materials can be corrected or directly scrapped.

[0090] Through precise dimension and weight detection, it is ensured that only qualified materials enter the warehouse, reducing the inflow of unqualified materials from the source, and thus reducing inventory risks; and quickly reacting to materials that do not meet the standards, guiding them to the exception handling port, allowing problems to be solved in a timely manner, and preventing unqualified materials from affecting subsequent processes; at the same time, automated warehouse location allocation reduces manual operation intervention, improves warehousing efficiency and rational utilization of resources, and ensures the smoothness of warehouse operations. At the same time, through the data records of each detection and warehousing process, managers can analyze the reasons for unqualified materials, formulate corresponding improvement strategies, and optimize supply chain management. Through the above detailed steps and mechanisms, the warehouse location allocation process realizes automation, precision, and high efficiency, plays a positive supporting role in the overall management of production and warehousing, and further promotes the intelligent process of modern logistics systems.

[0091] And during the weighing process, the unique code of the product is automatically read through RFID (Radio-Frequency Identification) or barcode technology and associated with the weighing data. This can ensure that the weight data of each batch of blank materials is accurately matched with its unique identifier.

[0092] Optionally, the visual inspection system includes a preset visual inspection model, and the material is defect-detected according to the preset criteria by the visual inspection system; the operation of grouping the trays for the materials that meet the preset criteria to obtain the grouped tray materials after binding includes:

[0093] Obtain the image data of the material;

[0094] Based on the image data, detect the material according to the preset visual inspection model to obtain a visual inspection result;

[0095] When the visual inspection result meets the preset criteria, bind the material to the corresponding tray to form the grouped tray material after binding;

[0096] When the visual inspection result does not meet the preset criteria, send the material to the abnormal processing port for abnormal detection.

[0097] Specifically, first photograph the material to be warehoused to obtain its image data. This can be done by a high-resolution camera or a visual sensor to ensure clear details are captured.

[0098] Use a preset visual inspection model (usually based on deep learning or computer vision algorithms) to analyze the acquired image data. This process includes: Material feature extraction: Identify features such as the edges, shapes, colors, and sizes of the materials. Defect identification: Compare the material features with the preset criteria to determine whether there are defects such as cracks, deformations, and stains on the materials. Generate a visual inspection result based on the results of the detection and analysis, and compare it with the preset warehousing criteria. The judgment basis includes the appearance, integrity, size, etc. of the materials to ensure compliance.

[0099] When the visual inspection result meets the preset criteria, the tray grouping operation will be performed to bind the qualified materials to the corresponding trays. The binding process may include the positioning and fixing of the materials, as well as recording information in the material intelligent management system (such as the material code, i.e., the material ID, and the tray code, i.e., the tray ID). The formed grouped tray materials after binding will be prepared for subsequent processing, including warehousing or distribution.

[0100] When the visual inspection result does not meet the preset criteria, for the unqualified materials, mark them as abnormal and automatically guide them to the abnormal processing port. At the abnormal processing port, these unqualified materials will be further detected or rechecked to ensure that the problems are handled in a timely manner.

[0101] All the detection results and tray grouping information will be recorded in the system database for subsequent tracking, analysis, and data statistics.

[0102] Through visual inspection technology, it is ensured that each incoming material meets the quality standards, reducing the risk of non-conforming materials flowing into the warehouse and maintaining the inventory quality. Moreover, automated image processing and defect detection significantly improve the detection efficiency, replacing manual inspection, greatly reducing labor costs and time consumption. And the non-conforming materials are immediately guided to the abnormal handling port, ensuring a rapid response when problems occur, reducing potential losses and impacts on subsequent processes. Also, the problem materials detected early are processed in a timely manner, reducing material rework and waste caused by subsequent defect discovery and improving the utilization efficiency of resources. At the same time, the data records of all inspection and palletizing activities provide a reliable basis for subsequent analysis, report generation, and decision support, helping management optimize operation processes and quality management.

[0103] Through efficient visual inspection and automated palletizing operations, enterprises can ensure the quality of materials and maintain an efficient incoming process. This series of precise management measures not only improve operation efficiency but also optimize the operation of the entire supply chain, contributing to the intelligent transformation in the modern logistics environment.

[0104] Optionally, the method for incoming materials of the materials further includes:

[0105] Obtain the actual waste data during the processing of the materials;

[0106] Analyze the actual waste data and the corresponding weighing information to obtain an analysis result.

[0107] Optionally, the analyzing the actual waste data and the corresponding weighing information to obtain an analysis result includes:

[0108] Obtain ratio data based on the actual waste data and the corresponding weighing information, and judge the ratio data according to a preset threshold;

[0109] When the ratio data exceeds the preset threshold, mark and feedback the materials; and evaluate the waste situation of the materials at different time periods through time series analysis.

[0110] Specifically, on the processing line of the materials, a waste collection module will be set up to automatically record the waste information generated during the processing. This information may include: Waste type: Different types of waste, such as scraps, defective products during processing, etc. Waste quantity: Real-time measurement of the generated waste, statistically counted by department or processing batch. Waste source: Record specifically which processing link (such as cutting, drilling, grinding, etc.) the waste is generated in for subsequent analysis.

[0111] In the processing stage of the materials, it is necessary to ensure that each batch of materials is weighed and the weighing information related to the waste data is recorded. The weighing information should include: Total weight of materials: that is, the total weight of the materials to be processed. Processing batch: the processing batch number corresponding to the waste data, which is convenient for tracking and analysis.

[0112] Integrate the actual waste data with the corresponding weighing information into a comprehensive data. This step involves data cleaning, format standardization, and duplicate removal, etc., to ensure the integrity and accuracy of the data.

[0113] Based on the collected waste data and weighing information, calculate the waste ratio for each processing batch. The formula is:

[0114]

[0115] Compare the calculated waste ratio with a preset threshold. The preset threshold can be determined based on historical data, industry standards, or internal quality control standards. According to the level of the ratio, classify the quality of the materials to be processed: for example, if the waste ratio is within the allowable range, it is qualified materials; if the waste ratio exceeds the threshold, it will be marked and feedback for additional investigation. And the materials with waste ratio exceeding the threshold will be automatically marked, and this information will be recorded for subsequent processing and tracking. A notice will be sent to the relevant responsible personnel to inform them that further analysis and processing are required for specific batches. In waste analysis, improvement suggestions for the processing process may be provided, such as optimizing the process, adjusting equipment, training operators, etc., to reduce waste generation.

[0116] In addition to immediate analysis, time series analysis will also be carried out to evaluate the trend of waste generation in different time periods. This may include trend assessment: analyzing the change trend of the waste ratio and identifying the time periods with high waste rates. And judge whether there are waste generation patterns related to processing modes, seasons, etc., in order to adjust the processing plan. Finally, a report can be automatically generated to record the analysis results, including waste situation, efficiency assessment, and improvement suggestions.

[0117] By analyzing the waste data in the processing process, enterprises can effectively monitor and control product quality to ensure that only materials meeting the standards enter the next process.

[0118] During the above process, after integrating the weighing data and product coding information, they are stored in the database of the Warehouse Management System (WMS). Such a database should have high data integrity and accuracy to facilitate subsequent metal scrap statistics and verification. And in the precious metal processing industry, the statistics and verification of metal scrap are particularly important. Through a high-precision weighing system, the weight of metal scrap can be accurately measured and tracked and managed through the WMS database. This helps to ensure the accuracy and efficiency in the process of recycling and reusing metal scrap. Through accurate weighing and data management, waste of metal scrap can be reduced and the utilization rate of resources can be improved. For example, the application of an iron scrap briquetting machine can reduce the material volume, lower the storage and transportation costs, while maintaining the quality of the waste iron scrap material, increasing the melting furnace rate, and thus creating economic value.

[0119] Optionally, the method for the material to enter the warehouse further includes:

[0120] Before the material arrives at the warehouse entrance, create an initial warehouse entry document based on the information of the material;

[0121] Among them, the initial warehouse entry document includes the main document information and the document detail list. The main document information at least includes the document number, the warehouse entry date, and the supplier information; the document detail list includes the category code of the material, the batch sequence number, the process number, and the quantity data.

[0122] Optionally, the binding of the material to the corresponding pallet further includes:

[0123] Perform a palletizing operation on the material and at least one pallet to form the palletized material after binding;

[0124] Based on the information of the palletized material after binding, automatically associate with the initial warehouse entry document and update the initial warehouse entry document so that it includes the material information of the palletized material after binding, where the material information is unique to ensure that each palletized material after binding is uniquely identified in the material intelligent management system.

[0125] Specifically, before the materials to be warehoused reach the warehousing entrance, collect the information related to these materials, including: Basic material information: such as material name, category, specification, supplier, etc. Warehousing date: Record the specific date when the materials arrive. Supplier information: including supplier name, contact information, etc., for subsequent query and tracking. Generate a document: Based on the collected information, an initial warehousing document will be automatically generated**, and this document contains the following content: Main document information: Document number: A unique identifier automatically generated for tracking and management. Warehousing date: The date when the materials arrive. Supplier information: The name and relevant information of the supplier. Document detail list: Category code: The classification code of each material. Batch sequence number: The sequence number identifying the material batch. Process number: The process number of the material during production. Quantity data: The quantity of the materials to be warehoused.

[0126] After the materials reach the warehousing entrance, palletizing operations will be carried out on the materials to be warehoused. The specific steps include: Identify the pallet: Determine the pallet corresponding to the materials to be warehoused, usually selecting a suitable pallet based on information such as the type, volume, and weight of the materials. Palletizing execution: Bind the materials to be warehoused with at least one pallet to form the palletized materials after binding. This process may involve: Material positioning: Ensure that the materials are correctly placed on the pallet. Fixing and marking: Fix the materials and mark relevant information (such as material number, batch number, etc.) on the pallet.

[0127] And the pallet has a unique pallet code. During the palletizing process, the pallet code is associated with the corresponding materials. After the palletizing operation is completed, the information of the palletized materials after binding will be automatically associated with the previously generated initial warehousing document. The specific steps include: Extract relevant information from the palletized materials, such as material number, quantity, pallet number, etc. Update the extracted material information to the initial warehousing document to ensure that the document detail list contains all the detailed information of the palletized materials after binding. Each palletized material after binding has a unique identification in the material intelligent management system to avoid duplication and confusion. This can be achieved by generating a unique material ID or barcode. At the same time, all updated warehousing document information, including the main document information and the detail list, will be recorded in the system database for subsequent query, auditing, and tracking.

[0128] Through systematic information collection and automatic update, the accuracy and integrity of the warehousing document are ensured, reducing problems caused by manual input errors. And each palletized material after binding has a unique identification, which is convenient for subsequent inventory management, material tracking, and auditing, improving the transparency of material management.

[0129] By automatically associating material information with incoming warehouse documents, managers can obtain the inventory status in real time, optimize inventory levels, and reduce the risks of inventory backlog and out-of-stock. Moreover, the recorded incoming warehouse documents and material information provide a basis for subsequent data analysis, assisting management in making decisions such as production planning, supply chain optimization, and cost control. At the same time, through accurate supplier information and material tracking, enterprises can establish closer cooperative relationships with suppliers and improve the overall efficiency of the supply chain.

[0130] Through automated initial incoming warehouse document creation and palletizing operations, enterprises can achieve more efficient and accurate material incoming warehouse management. This process not only optimizes the incoming warehouse process but also provides a solid data foundation for subsequent inventory management and decision support, helping enterprises maintain an advantage in the highly competitive market environment.

[0131] In some preferred embodiments, the method for obtaining incoming warehouse documents can be to obtain data from ERP and MES systems. Specific interface implementation details need to be confirmed with each platform to ensure accurate data transmission.

[0132] It can also be created through the WMS page. That is, the WMS system allows self-creation of pages and setting of different permissions. Only users with advanced permissions can perform advanced operations such as page creation. At the same time, operation logs need to be recorded to track user behavior and system status.

[0133] Content format of incoming / outgoing warehouse documents: Main information of the document: including document number, document type, product business number, and document creation time. List of document details: including category code (e.g., 01 represents the type), batch sequence number (referring to the batch and sequence of materials, used to track and manage material batches), process number (referring to the steps or operation numbers of material processing, used to track the production process), and planned quantity.

[0134] Among them, the materials to be warehoused include raw materials, measuring tools, jigs, etc. For the processing of raw material incoming warehouse documents in the ERP system: The raw material incoming warehouse documents in the ERP system are not bound to specific batch sequence numbers and process numbers. These two fields are empty or default to 0. For the processing of incoming warehouse documents for measuring tools and jigs, the process number defaults to empty or 0, and the batch sequence number is empty or defaults to 0. Moreover, for different types of documents, the input rules are different. The WMS system needs to implement input anti-fooling and anti-error technical measures for the filling page to reduce human errors.

[0135] During the incoming warehouse process, the feedback process of incoming / outgoing warehouse documents: First, query the incoming / outgoing warehouse document information. After selecting the document to be operated on, synchronize the document information and the actual quantity to ERP and MES. Multiple selections are supported for the selection operation, and there should be a clear indication of whether the document has been synchronized to other systems. The documents created by the WMS do not need to be synchronized to ERP and MES.

[0136] And during the MES material calling process, that is, after MES calls for materials, WMS needs to feedback the quantity of previous tasks to MES. The material calling process can include simultaneously calling for raw materials, measuring tools, jigs, etc., that is, creating corresponding task requirements, forming corresponding material call sheets, and waiting for task sheets (i.e., tasks waiting in line).

[0137] WMS feeds back to MES according to the quantity of previous tasks, that is, all the tasks currently existing, that is, informs MES of the current waiting-in-line process.

[0138] It should be noted that the acquisition methods and content formats of the outbound documents and inbound documents in this embodiment are the same.

[0139] Optionally, the method for warehousing the material further includes:

[0140] When the grouped and palletized material after binding is out of the warehouse, the grouped and palletized material after binding is transported as a whole to the designated target location, and the grouped and palletized material after binding is unbound.

[0141] Construct an outbound document based on the received outbound request, and sort the outbound document according to the preset priority.

[0142] Specifically, after receiving the outbound request for the grouped and palletized material, the grouped and palletized material to be out of the warehouse will be identified. The material management personnel or system operator or robot system will transport the required grouped and palletized material as a whole to the designated target location (such as a warehouse, a transport vehicle, or a production line). After transporting the grouped and palletized material to the target location, the grouped and palletized material after binding needs to be unbound. The specific steps are as follows:

[0143] Remove the marks or packages on the pallet to ensure that all materials can be independently identified in the system. According to the previously bound information, unbind the materials on the pallet one by one, and update the material status in the system to ensure that they can be managed and tracked individually.

[0144] The received outbound request may be initiated by other departments (such as sales, production, or warehouse management).

[0145] An outbound document is automatically generated based on the information of the outbound request. The outbound document should include: Outbound document number: A unique number used for identification and tracking. Outbound date: The specific date when the outbound operation is recorded. Material information: including material name, quantity, batch number, pallet number, etc. Destination information: Specify the target location or customer information.

[0146] Sort the outbound documents according to the preset priority. The priority may depend on the following factors: Customer order priority: Give priority to processing important customers or urgent orders. Shelf life of materials: First, ship out materials approaching their expiration dates to reduce losses. Inventory status: Prioritize shipping out materials with high inventory levels but large demand. The sorted outbound documents will generate an outbound operation list to guide warehouse staff to execute outbound tasks in an orderly manner. And all outbound operations and results will be recorded in the system for subsequent query and auditing. The generation and association of outbound documents will update the real-time status of material inventory.

[0147] For the full-container shipping process, it reduces the handling time of single-piece materials and improves the overall efficiency of outbound operations. And through the unbundling operation and the generation of outbound documents, it ensures the accuracy and integrity of the outbound materials, reduces the error rate, and prevents missing or misshipping. At the same time, through the timely update of outbound information, the system can reflect the inventory status in real time, helping management reasonably arrange the inventory level and reduce inventory backlog. And the systematic management and sorting of outbound documents help ensure the standardization of the outbound process, reduce human interference, and rely on data-driven decision-making.

[0148] Through full-container shipping and systematic outbound document processing, enterprises can achieve efficient and accurate outbound management. This process optimizes the material flow, ensures inventory accuracy, improves customer service levels, and realizes stronger inventory control capabilities and operational efficiency.

[0149] For the process of in-site production where PDA and AGV (Automated Guided Vehicle) can be used for the transfer of items between processes. For example: Use PDA to scan the barcode of the station where the goods to be moved are located. The PDA reads the information through RFID or barcode technology. Enter the target area for planned handling on the PDA. The PDA sends a request to the AGV control system, requesting the AGV to execute the handling task. After receiving the handling request, the AGV automatically drives to the specified station according to the built-in navigation system. The AGV confirms the location of the goods through identification technology (such as barcode, RFID or vision system) and picks up the goods. The AGV transports the goods to an idle station within the target area.

[0150] If there is no idle station in the target area, the AGV system should provide a prompt message.

[0151] If the stations in the target area are full, the AGV control system issues a prompt to inform that there is no idle station. Based on the prompt message, the system can re-plan the handling target or wait for an idle station.

[0152] After the goods are successfully transported to the target station, the AGV system should send a confirmation message of task completion. And after confirming the task completion, update the goods location information to the WMS (Warehouse Management System).

[0153] It should be noted that real-time communication is required between the PDA and the AGV to ensure that handling requests and status updates can be transmitted instantaneously. Moreover, the AGV requires a high-precision navigation system to ensure accurate arrival at the designated station. At the same time, the system should have an error handling mechanism, such as incorrect station identification, incorrect path planning, etc.

[0154] Moreover, the AGV should have an obstacle avoidance system during the handling process to avoid collisions with personnel or other obstacles. At the same time, optimize the path planning to reduce the empty running and waiting time of the AGV and improve the handling efficiency.
