Description

Technical Field

[0001] This invention relates to the field of material distribution technology in production workshops, and particularly to a material distribution method and system. Background Technology

[0002] Currently, in the vehicle production process, there are typically thousands of workstations on the production line, each storing the materials needed for production. As production progresses, the materials at each workstation gradually decrease. When a workstation is about to run out of materials, it needs to be replenished so that the material preparation personnel can replenish the materials for that workstation in a timely manner.

[0003] Currently, there are two main methods for replenishing materials in production: The first method is to manually summarize the missing materials and then call for more. However, this management method is not only labor-intensive, but also has large errors and low efficiency in the data summarized and counted manually. The second method is to deliver materials according to the work order plan and production rhythm at the predetermined time and in the predetermined quantity. However, this delivery method is too rigid and cannot be flexibly adjusted in real time according to the production situation. The error tolerance and precision cannot meet the current needs of information management and refined management.

[0004] Therefore, how to deliver the right materials and the right quantity to the production station at the right time, and ensure that the delivery rhythm is consistent with the production rhythm, is an urgent problem to be solved. Summary of the Invention

[0005] The technical problem solved by this invention is to provide a material distribution method and system that can automatically send distribution instructions based on the actual progress of the production process, eliminating the drawbacks of manual operation and ensuring the timeliness of material distribution; and it provides comprehensive support for a database of parameters such as workstations, processes, and materials, realizing on-demand distribution and ensuring the accuracy of distribution.

[0006] The technical problem solved by this invention is achieved by the following technical solution:

[0008] In a preferred embodiment of the present invention, the step of generating a material delivery task based on the production data information further includes: obtaining the target material type and target material usage corresponding to the target workstation based on the production data information; and generating a material delivery task based on the target material type and target material usage.

[0009] In a preferred embodiment of the present invention, the step of generating a material delivery task based on the production data information further includes: obtaining start time information when the product passing signal is received; obtaining the first pull usage time of the target workstation based on the start time information and the process cycle time; and generating a material delivery task based on the first pull usage time, the target material type, and the target material usage.

[0010] In a preferred embodiment of the present invention, the step of generating a material delivery task based on the first pull usage time, the target material type, and the target material usage further includes: obtaining the material delivery time from the supply warehouse to the target workstation; and generating a material delivery task based on the material delivery time, the first pull usage time, the target material type, and the target material usage.

[0011] In a preferred embodiment of the present invention, before the step of receiving the product passing signal, the following steps are included: a product detection device is installed on the workstation for detecting the product, and when the product is detected, the product detection device sends the product passing signal to the ERP system.

[0012] In a preferred embodiment of the present invention, the step of generating a material delivery task based on the production data information when a product over-point signal is received further includes: when no product detection device is installed at the target workstation, acquiring the preceding workstation that detected the product; acquiring first time information of the preceding workstation arriving at the target workstation; acquiring second time information of the product detection device at the preceding workstation detecting the product; acquiring a second pull usage time based on the first time information, the second time information, and the process cycle time; acquiring the material delivery duration, the target material type, and the target material quantity; and generating a material delivery task based on the second pull usage time, the material delivery duration, the target material type, and the target material quantity.

[0013] In a preferred embodiment of the present invention, before the step of replenishing the target workstation with materials according to the material delivery task, the method includes: determining the delivery departure time of the material delivery device based on the first pull usage time and the material delivery duration.

[0014] In a preferred embodiment of the present invention, the step of replenishing materials to the target workstation according to the material delivery task includes: generating a material delivery trajectory according to the material delivery task and the target workstation; and controlling a material delivery device to deliver materials to the target workstation according to the material delivery trajectory.

[0015] A material distribution system includes: a product detection module, used to generate a product check signal when a product is detected; a production management module, used to acquire production data information, the production data including workstations, processes, process cycles, and material usage at each workstation, to acquire target workstations for planned material replenishment, and to generate a material distribution task based on the production data information when a product check signal is received; and a warehouse management module, used to replenish materials to the target workstations according to the material distribution task.

[0016] In a preferred embodiment of the present invention, the production management module is an ERP system, the product inspection module is a fixed barcode scanning device, and the warehouse management module is a warehouse system.

[0017] The technical effect achieved by the above-mentioned technical solution of the present invention is that by using a material distribution scheme based on process point pull, not only are labor costs saved, but also the phenomenon of work stoppages and production stoppages caused by human error is eliminated, and on-demand, timely and quantity distribution is truly achieved, which greatly improves production efficiency.

[0026] It should be understood that although the terms first, second, third, etc., may be used herein to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this document, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0029] It should be noted that step designations such as S11 and S12 are used in this document for the purpose of more clearly and concisely describing the corresponding content, and do not constitute a substantial limitation on the order. In specific implementation, those skilled in the art may execute S20 first and then S10, etc., but these should all be within the protection scope of this application.

[0030] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0031] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0032] The equipment involved in the applied technical solution includes, but is not limited to, the following: 1) a fixed barcode scanning device; 2) an ERP system; and 3) a warehousing system. The ERP system has two main functions: 1) configuring information such as the production cycle time and material usage for each production line, each product, and each material, and maintaining basic data and related configuration databases; 2) receiving the passing signals sent by the fixed barcode scanning device on the final assembly line, calculating and generating delivery tasks, and sending them to the warehousing system.

[0033] Please see Figure 1 , Figure 1This is a schematic flowchart illustrating a material distribution method according to an embodiment of the present invention.

[0034] like Figure 1 As shown, the method described in one embodiment of the present invention includes the following steps:

[0035] S11: Obtain production data information, including workstations, processes, process cycles, and material configurations.

[0036] Alternatively, workstations and processes refer to the workstations and processes that a product needs to use or go through during production on the final assembly line. A single production process may require the coordination of multiple workstations.

[0037] Alternatively, cycle time refers to the interval between the input or output of two identical products in a certain process on an assembly line.

[0038] Optionally, a workstation is the most basic production unit in the production process, where materials needed to produce products are stored. The types and quantities of materials stored at different workstations vary and are configured according to the production needs of the products.

[0039] Optionally, material configuration includes: material usage and material type.

[0040] Material usage refers to the table of material usage required for each process and / or workstation. Specifically, the material usage required for the production of a product can be found by referring to the table based on the process and / or workstation in which the product is located. For example, workstation A uses material 1, workstation B uses material 2, and so on.

[0041] Material types refer to the list of material types required for each process and / or workstation. Specifically, the material types required for a product can be found by referring to the list based on the process and / or workstation in which the product is located. For example, workstation A uses material type a, workstation B uses material types b and c, etc.

[0042] The material usage table and material type table can be summarized as a material allocation table, which contains the types and quantities of materials used in each process and / or workstation of the product.

[0043] This technical solution is as follows: Figure 3 As shown, it mainly consists of three parts: data maintenance, task generation, and task execution.

[0044] Data maintenance includes, but is not limited to: workstation data, process data, product production cycle time data, product material usage data, and material delivery time data. Workstation, process, product production cycle time, and process cycle time data can be obtained from the production system (such as the MES system), product material usage and material types can be obtained from the R&D design system (such as TC, PLM, etc.), and material delivery time data can be obtained from the warehousing system or procurement system.

[0045] Optionally, before the step of receiving the product passing signal, the process includes: a product detection device is installed on the workstation to detect the product, and when the product is detected, the product detection device sends the product passing signal to the ERP system.

[0046] For example, the product inspection device can be a fixed barcode scanning device, such as a barcode scanner, installed at the workstation or on the corresponding assembly line. The barcode scanner confirms whether a product has been detected by scanning the barcode on the product. When a product is detected, it outputs a product pass signal to the ERP system.

[0047] This embodiment is based on a specific application of a fixed barcode scanning device, which is essentially a problem of collecting and uploading a pass-through signal. Therefore, it is not limited to a fixed barcode scanning device; PDA scanning or manual input can also be used, all of which are alternative methods for collecting pass-through signals in this invention and may form alternative solutions to this scheme.

[0048] S12: Upon receiving a product arrival signal, generate a material delivery task based on the production data information.

[0049] Task generation refers to the process of calculating and generating material delivery tasks based on product transit signals and using basic data and configurations such as previous workstations, processes, and material usage.

[0050] Optionally, the production cycle time and material delivery frequency can be configured according to different workstations and different materials to flexibly meet the material delivery needs of different production lines.

[0051] Optionally, the step of generating a material delivery task based on the production data information further includes: obtaining the target material type and target material usage corresponding to the target workstation based on the production data information; and generating a material delivery task based on the target material type and target material usage.

[0052] After confirming the target workstation for the planned material replenishment, obtain the types and quantities of materials consumed by the product at the target workstation from the material configuration table based on the target workstation information.

[0053] Optionally, the step of generating a material delivery task based on the production data information further includes: obtaining start time information when the product passing signal is received; obtaining the first pull usage time of the target workstation based on the start time information and the process cycle time; and generating a material delivery task based on the first pull usage time, the target material type, and the target material usage.

[0054] Upon receiving the product passing signal at the target workstation, it indicates that the product is being produced at the target workstation and requires the consumption of the target material type (e.g., 3 A parts) in the target material usage quantity at the target workstation.

[0055] Optionally, the first pull time can be the time it takes for the delivery device to reach the target workstation.

[0056] Optionally, the start time information is the time when the product's time-pass signal is received. For example, when an ERP system receives a product's time-pass signal, it obtains the real-time time information. The cycle time is the time required for a product to complete production at its corresponding workstation.

[0057] Optionally, the pull usage time can indicate the time when the product is completed at the target workstation, and the target material type can be replenished to the target workstation with the target material quantity after production is completed.

[0058] like Figure 4 As shown, when the Xth product on a production line passes the fixed barcode scanning device (e.g., a barcode scanner) at station n, the ERP system receives the pass signal from the fixed barcode scanning device, triggering the calculation and issuance of a pull task. Assuming the cycle time at station n is 10 minutes, based on the current time (i.e., the time when the pass signal is received), a planned material pull / delivery task for the [X+(10 / cycle time)]th product at station n is generated and issued to the warehousing system. The pull time is equal to the current time plus 10 minutes. This is a case of current station pulling current station.

[0059] In addition to the method of the current workstation pulling the current workstation, the present invention can also use the method of the previous workstation pulling the next workstation.

[0060] like Figure 2 As shown, the material delivery task generation method of the present invention when no product inspection device is installed at the current workstation includes the following steps:

[0061] S21: When the target workstation does not have a product testing device installed, obtain the previous workstation where the product was detected;

[0062] S22: Obtain the first time information of the arrival of the target workstation from the preceding workstation;

[0063] S23: Obtain second time information when the product detection device at the preceding workstation detects the product;

[0064] S24: Obtain the second pulling time based on the first time information, the second time information, and the process cycle time;

[0065] S25: Obtain the material delivery time, the type of the target material, and the quantity of the target material;

[0066] S26: Generate a material delivery task based on the second pull usage time, the material delivery duration, the target material type, and the target material usage.

[0067] Alternatively, if the target workstation does not have a product testing device installed, the pull time can be confirmed by checking the workstations where product testing devices have already been installed.

[0068] Among them, the process cycle time is the process cycle time of station m; the first time information of the preceding station arriving at the target station is the interval time required for the product to arrive at the target station after entering the preceding station.

[0069] Optionally, the first pull time can be the time it takes for the delivery device / material delivery device to reach the target station. After the second pull time is reached, the product is completed at station m, and the delivery device can replenish the materials consumed during the production of the product at station m. For example, if one part a is used in the production of the product at station m, then one part a will be replenished.

[0070] like Figure 4 As shown, since not every workstation has a fixed barcode scanning device, the present invention can also pull the planned materials of the [X+(10 / beat)]th workstation m from the previous workstation, thereby confirming that the pulling time of workstation m = current time + 10 minutes + n interval time to workstation m.

[0071] Optionally, the step of generating a material delivery task based on the first pull usage time, the target material type, and the target material usage further includes: obtaining the material delivery time from the supply warehouse to the target workstation; and generating a material delivery task based on the material delivery time, the first pull usage time, the target material type, and the target material usage.

[0072] Material delivery time is the time required for a material delivery device to travel from the supply warehouse to the target workstation. Material delivery time can be calculated by the warehousing system based on the travel speed of the material delivery device and the distance from the supply warehouse to the target workstation, or it can be calculated by averaging the travel times of multiple material delivery devices traveling at the target speed to the target workstation.

[0073] S13: Obtain the target workstation for planned material replenishment;

[0074] Optionally, the station that issues the product passing signal is the target station; if there is a station that does not have a product detection device installed, then the station that issues the product passing signal and subsequent stations in the same process that do not have a product detection device installed can all be target stations.

[0075] S14: Replenish materials to the target workstation according to the material delivery task.

[0076] Optionally, before the step of replenishing materials to the target workstation according to the material delivery task, the method includes: determining the delivery departure time of the material delivery device based on the first pull usage time and the material delivery duration.

[0077] Material delivery devices can be manual forklifts or AGV robots, etc.

[0078] Once the task is executed, the ERP system calculates and generates pull tasks / material delivery tasks. Then, through system integration with external systems such as enterprise warehousing or procurement systems, the external systems prepare the goods and deliver them to the designated workstations on time via manual forklifts or AGV robots, achieving seamless integration of production and logistics.

[0079] To prevent the material delivery device from failing to replenish materials to the target workstation in a timely manner, the departure time of the material delivery device can be determined by tracking usage time and material delivery duration.

[0080] Optionally, after receiving the material delivery task, the warehousing system selects the type and quantity of materials to be assembled by the material delivery device based on information such as the target material type and target material usage in the material delivery task, and confirms the departure time of the material delivery device from the supply warehouse based on the material delivery duration and pull usage time.

[0081] Optionally, the step of replenishing materials to the target workstation according to the material delivery task includes: generating a material delivery trajectory based on the material delivery task and the target workstation; and controlling a material delivery device to deliver materials to the target workstation according to the material delivery trajectory.

[0082] Optionally, the ERP system stores the location information of the target workstation. When sending a material delivery task to the warehousing system, the location information of the target workstation is also sent to the warehousing system. Therefore, during material delivery, a material delivery trajectory can be generated based on the location information of the supply warehouse and the target workstation. In this embodiment, the material delivery trajectory is generated using Dijkstra's algorithm to generate the shortest path, thereby improving material delivery efficiency.

[0083] Optionally, the material delivery device travels to the target workstation according to the material delivery trajectory, thereby replenishing the target workstation with materials.

[0084] The material distribution method of the present invention generates a material distribution task based on data such as process, workstation, and material usage when a product transit signal is received, thereby sending a distribution instruction to the warehousing system. This eliminates the drawbacks of manual operation and generates distribution tasks based on the actual progress of the production process, ensuring the timeliness of material distribution. It also provides comprehensive support from a database of parameters such as workstation, process, and material, which confirms the type and quantity of materials and enables on-demand distribution, ensuring the accuracy of distribution.

[0085] Please see Figure 5 , Figure 5 This is a block diagram of a material distribution system according to an embodiment of the present invention.

[0086] like Figure 5 As shown, this embodiment provides a material distribution system, including: a product detection module, used to generate a product check-through signal when a product is detected; a production management module, used to acquire production data information, the production data including workstations, processes, process cycles, and material usage at each workstation, to acquire target workstations for planned material replenishment, and to generate a material distribution task based on the production data information when a product check-through signal is received; and a warehouse management module, used to replenish materials to the target workstations according to the material distribution task.

[0087] In this embodiment of the invention, a material distribution system automatically sends distribution instructions based on the actual progress of the production process, eliminating the drawbacks of manual operation and ensuring the timeliness of material distribution; it provides comprehensive support from a database of parameters such as workstations, processes, and materials, enabling on-demand distribution and ensuring the accuracy of distribution.

[0088] Optionally, the warehouse management module is a warehouse management system (WMS), the production management module is an ERP system, and the product inspection module is a fixed barcode scanning device. The warehouse management system uses manual forklifts or AGV robots for material delivery. In this embodiment, the ERP system identifies the target workstation requiring material replenishment based on product transit signals, then determines the type and quantity of materials needed based on the target workstation, and further determines the pull time based on the workstation's cycle time and the time it takes to receive the product transit signal. Finally, it generates a material delivery task based on the material type, quantity, pull time, and target workstation location, and sends the task to the warehouse management system. The warehouse management system then replenishes the target workstations with materials according to the delivery task.
