Description

Technical Field

[0001] This invention belongs to the field of complex product manufacturing and assembly technology, specifically relating to a manufacturing unit deployment method that integrates single-point progressive forming and wire-controlled equipment. Background Technology

[0002] In the production and assembly of complex products, effectively organizing and managing the resources of manufacturing units, optimizing manufacturing processes, and improving product production efficiency and quality are crucial issues facing production operations management. Currently, workshop resource allocation and management largely rely on manual operation, making it impossible to achieve refined production process control, ensuring product assembly quality and production efficiency, and rarely considering the impact of changes in resource status on assembly plans and production scheduling.

[0003] The uncertainty and dynamic changes in manufacturing resources can severely impact the normal operation of manufacturing workshops. Currently, manufacturing resources suffer from incomplete control mechanisms, poor timeliness of monitoring data, and low levels of intelligent scheduling. Dynamic management and optimized allocation of these resources are crucial for achieving efficient production. However, traditional resource management methods are mostly static, meaning they cannot be changed once set and are ill-suited to complex and changing production environments. Furthermore, the production and assembly of complex products requires a management and control method that can accurately describe resource status, dynamically adjust resource allocation, and optimize the assembly process in real time. However, existing management methods cannot accurately describe resource status and lack effective means of resource allocation and manufacturing process optimization. Summary of the Invention

[0004] Purpose of the invention: To address the problems existing in the above-mentioned background technology, the present invention provides a manufacturing unit deployment method that integrates single-point progressive forming and wire-controlled equipment.

[0005] Technical Solution: The present invention adopts the following technical solution: a manufacturing unit deployment method integrating single-point progressive forming and wire-controlled equipment, comprising the following steps:

[0006] Step 1: Based on the input and output areas of the complex product manufacturing unit and the spatial division criteria of the manufacturing process, determine the deployment of the manufacturing unit area as follows: storage area, single-point progressive forming processing unit (processing input area, single-point progressive forming processing center, processing output area), wire-controlled equipment assembly unit (assembly input area, assembly center, assembly output area), and assembly completion area.

[0007] Step 2: Using resources such as complex products, assembly centers, wire-controlled equipment, and assembly completion areas in the manufacturing process, establish three assembly resource models: a single-point progressive forming processing unit Petri net model, a wire-controlled equipment assembly unit Petri net model, and an assembly completion area Petri net model.

[0008] Step 3: Based on the established manufacturing resource model, determine the Petri net model of the single-point progressive forming machining center, which includes machining center acquisition information, machining center status inspection information, machining resource verification information, machining task completion information, and machining equipment maintenance information. The Petri net model of the wire-controlled equipment assembly unit includes wire-controlled equipment acquisition of complex product handling information, wire-controlled equipment status inspection information, wire-controlled equipment handling of workpiece information, workpiece storage information, workpiece handling completion information, wire-controlled equipment reset information, and wire-controlled equipment maintenance information. The Petri net model of the assembly completion area includes available storage space information and occupied storage space information.

[0009] Furthermore, the deployment of the manufacturing unit spatial region in step 1 is specifically implemented as follows:

[0010] The raw materials for complex products in the storage area are transported to the processing input area by the handling equipment to wait for processing. The workpieces are processed in the processing center and then transported to the processing output area. The workpieces are then transported to the assembly input area by the handling equipment. Next, the workpieces are assembled in the assembly output area of ​​the assembly center by the wire-controlled equipment. This process is repeated until the complex product is fully assembled. Finally, the complex product in the assembly output area is transported to the assembly completion area by the handling equipment.

[0011] Furthermore, step 2 establishes Petri net perception models for the three types of assembly resources, specifically implemented as follows:

[0012] Step 21: Petri net model of single-point progressive forming processing unit: The main activities of the processing unit include the transport equipment moving the raw materials from the processing input area to the processing center for processing, and the transport equipment moving the finished workpiece to the processing output area after processing. The processing unit has a waiting processing state, an inspection processing state, a processed workpiece state, and a processing equipment maintenance state.

[0013] Step 22: Constructing the Petri net model of the wired control equipment assembly unit: The wired control equipment uses tooling to transport workpieces from the assembly input area to the assembly output area of ​​the assembly center, repeating the process. Assembly tasks for complex products are completed at the assembly center using the wired control equipment. The wired control equipment automatically resets with a single click after the transport task is completed. The wired control equipment is a cube or cuboid tooling with six degrees of freedom, each controlled by a rope. The tooling can be equipped with mechanical, hydraulic, magnetic, or vacuum chuck clamps, and can be used for workpiece transport, workpiece assembly, quality inspection, data recording, and analysis. The wired control equipment has four states: waiting to be transported, transporting workpieces, reset, and maintenance.

[0014] Step 23: Constructing the Petri net model of the assembly completion area: The main activities in the assembly completion area include the transport of complex products from the assembly output area to the assembly completion area using handling equipment. The assembly completion area has a certain storage capacity, including both available and occupied storage space. Wired control, handling equipment, and the assembly center can access the storage capacity information of the assembly completion area via RFID to realize the handling and storage of complex products.

[0015] Furthermore, the Petri net model of the single-point progressive forming processing unit established in step 3 specifically includes the following information:

[0016] 1) Information Acquisition by the Machining Center: The machining center acquires the tag information of the workpiece at the input and output positions by configuring RFID, identifies whether the workpiece is in a waiting state for processing, and obtains the personnel, equipment, tools and standard operating instructions required to process the workpiece;

[0017] 2) Machining Center Status Check Information: After receiving a machining task, the machining center first verifies whether personnel, equipment, and tools are in a ready state. If so, the machining center is in a normal state and can complete the next machining task;

[0018] 3) Processing Resource Verification Information: The processing center obtains the tag information of the personnel, equipment, and tools required for processing the workpiece via RFID. This triggers an instruction to verify the information in the tags and standard operating instructions. If the two sets of information match, processing can proceed. Otherwise, the anomaly information is uploaded to the system for verification and resource reallocation.

[0019] 4) Machining Center Task Completion Information: Once the workpiece, personnel, equipment, tools, and operating instructions are ready, the machining task begins. When machining begins, the number of workpieces in the machining input area decreases by 1, and the number of workpieces in the machining output area increases by 1. Additionally, the machining center checks if there is storage space for a workpiece in the machining output area. If not, it continues to wait; if so, the workpiece is moved to the machining output area, and the storage space in the machining output area decreases by 1.

[0020] 5) Processing equipment maintenance information: The machining center may malfunction during the processing. In addition to tools and equipment, regular maintenance is also required.

[0021] Furthermore, the Petri net model of the wire-controlled equipment assembly unit established in step 3 specifically includes the following information:

[0022] 1) Obtaining workpiece handling information via wired control equipment: The workpiece is tagged with information and its tag information is obtained through the RFID system configured on the wired control equipment. The workpiece is marked as awaiting handling, and its handling path is obtained.

[0023] 2) Check the status information of the wired control equipment: During the workpiece handling process, it is necessary to understand whether the wired control equipment is in a ready state, that is, whether it can complete the task of handling the workpiece. If the warning light is not on, it means that the handling equipment is in a ready state and can complete the task of handling the workpiece. If the warning light is on, it means that the wired control equipment is in an abnormal state, and product handling must wait for the wired control equipment status to change to a ready state;

[0024] 3) Workpiece handling information of wired control equipment: When resources such as workpiece, wired control equipment, and wired path information are in a ready state, handling activities are carried out. When a workpiece is transported, the number of workpieces in the assembly input area decreases by 1, and the number of workpieces in the assembly output area increases by 1;

[0025] 4) Workpiece storage information and workpiece handling completion information: The first step is to determine whether there is available space in the assembly input area or assembly output area of ​​the assembly center. If so, handling begins. When a workpiece is moved to the assembly input area by the handling equipment, the number of workpieces in the assembly output area increases by 1, and the number of workpieces in the assembly input area decreases by 1. If not, if storage space is available in the assembly input or assembly output area, the process waits and continues. When the wire-controlled equipment completes the handling of the workpiece according to the handling path, the electronic tag information of the next workpiece can be marked.

[0026] 5) Maintenance information for wired control equipment: In addition to the possible malfunctions that may occur during the handling of workpieces, which require shutdown for maintenance, the wired control equipment also needs to be regularly maintained according to the maintenance standards after a certain period of operation.

[0027] Furthermore, the Petri net model of the assembly completion area established in step 3 specifically includes the following information:

[0028] 1) Available storage space information: When the RFID of the handling equipment or assembly center detects that there is storage space for workpieces in the assembly completion area, the handling equipment will move or transfer the workpieces in the assembly output area, that is, the assembly completion area is in the state of available storage space.

[0029] 2) Storage space occupancy information: When the RFID of the handling equipment or assembly center detects that there are workpieces occupying storage space in the assembly completion area, the assembly output area will trigger an alert. At this time, the assembly completion area is in the state of occupying storage space.

[0030] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: (1) Traditional manufacturing units generally divide the processing and assembly areas according to the different parts of complex products, which leads to low space utilization and reduced efficiency due to untimely updates of manufacturing plans. The present invention divides the space area of ​​the manufacturing unit into zones, effectively divides different functional areas, realizes the optimal allocation of resources, and improves processing and assembly efficiency and product quality; (2) The present invention establishes three Petri net models of resources to accurately describe the relationship and interaction between resources, thereby reducing assembly complexity and solving problems such as reduced efficiency of resource allocation optimization and insufficient dynamic response capability of resources; (3) Traditional assembly equipment has three degrees of freedom and can only move in the x, y, and z directions. The wire-controlled equipment of the present invention has six degrees of freedom and can also rotate in the x, y, and z directions. It can move and rotate freely in three-dimensional space by using rope control, quickly adapt to the needs of different assembly tasks, and greatly improve the processing and assembly efficiency and the degree of automation of manufacturing; (4) The present invention realizes the functions of processing and assembly status inspection, resource verification, task completion, perception and management of storage space status, improving manufacturing accuracy and product handling and storage efficiency.

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] Example: Figure 1 As shown, the present invention provides a manufacturing unit resource deployment method that integrates single-point progressive forming and wire-controlled equipment, specifically including the following steps:

[0036] Step 1: Based on the input and output areas of the complex product manufacturing unit and the spatial division criteria of the manufacturing process, the manufacturing unit space area is partitioned and deployed, specifically as follows:

[0037] ① Taking the deployment of a manufacturing unit for a complex product (q) intended for satellites as an example, such as Figure 2As shown, the manufacturing unit space is deployed as follows: a storage area (c0), a single-point progressive forming processing unit including a processing input area (p0), a processing center (m0), a processing output area (p1), a wire-controlled equipment assembly unit including an assembly input area (s0), an assembly center (a0), an assembly output area (s1), and an assembly completion area (c1). The manufacturing unit also includes handling equipment (w0-w2), wire-controlled equipment (t0-t1), a KUKA robotic arm (k0), assembly personnel (o1-o4), and complex products (q), such as... Figure 3 As shown.

[0038] ② Based on the above spatial deployment, the storage area (c0) transports the pseudo-satellite structure plates (z0-zn) to the processing input area (p0) of the metal single-point progressive forming machining center (m0) via an AGV (Automatic Guided Vehicle) robot (w0) to await processing. The KUKA robotic arm (k0) is programmed to perform shape processing on the structure plate in the machining center (m0) and then transported to the processing output area (p1). The AGV (w1) transports the structure plate to the assembly input area (s0) of the assembly center (a0). Then, the assembly output area (s1) of the assembly center (a0) is assembled by a wire-controlled device (t0). The process is repeated until the pseudo-satellite complex product (q) is assembled and finally transported to the assembly completion area (c1) by the handling equipment (w2).

[0039] Step 2 establishes Petri net perception models for the three types of assembly resources, specifically implemented as follows:

[0040] ① Construct a Petri net model for a single-point progressive forming processing unit: The processing activity of the processing unit is that the transport equipment (w0) moves the raw workpiece from the processing input area (p0) to the processing center (m0) for processing. After processing, the finished workpiece is moved to the processing output area (p1) by the transport equipment (w1). The processing unit has a waiting processing state, an inspection processing state, a processed workpiece state, and a processing equipment maintenance state.

[0041] ② Construct a Petri net model for the assembly unit of the wire-controlled equipment: The wire-controlled equipment (t0) transports the satellite structure plate (z0) from the assembly input area (s0) to the assembly output area (s1) of the assembly center (a0) in a cyclical manner. The assembly task of the complex satellite product is completed in the assembly center (a0) by the wire-controlled equipment (t0, t1). The wire-controlled equipment (t0, t1) automatically resets with one click after the transport task is completed. The wire-controlled equipment has six degrees of freedom and is a cube-shaped fixture. Each degree of freedom is controlled by a rope. A vacuum suction cup clamp is installed below the fixture. The wire-controlled equipment uses the vacuum suction cup to transport the workpiece, adsorbing it from the assembly input area (s0) to the assembly table in the assembly input area (s1). The wire-controlled equipment assembles the workpiece according to predefined assembly procedures and methods, making precise position adjustments and fixing parts according to design requirements to ensure the accuracy and reliability of the assembly. The wire-controlled equipment uses sensors and a vision system for quality inspection, monitoring and measuring key parameters during the assembly process to ensure that the workpiece quality meets requirements. The wire-controlled equipment records and stores data during the assembly process, including the workpiece position, tools used, and torque. This data can be used to analyze and optimize the efficiency and quality of the assembly process. The wire-controlled equipment has four states: waiting to be transported, transporting workpiece, resetting, and maintenance.

[0042] ③ Constructing a Petri net model for the assembly completion area: The main activities in the assembly completion area (c1) include the transport equipment (w0) moving the complex product (q) from the assembly output area (s1) to the assembly completion area (c1). The storage area has a certain storage capacity, including two states: available storage space and used storage space. The wire control (t0-t1), the transport equipment (w2), and the assembly center (a0) access the storage capacity information of the assembly completion area through RFID, ultimately realizing the transport and storage of the complex product (q).

[0043] The Petri net model for the single-point progressive forming processing unit established in step 3 is implemented as follows:

[0044] 1) Information Acquisition by the Machining Center: The machining center (m0) is equipped with RFID to acquire the tag information (q0, q1) of the workpiece at the machining input and output positions, identify that the workpiece is in a waiting state for processing, and obtain the personnel (o2), equipment (k0), tools and standard operating instructions required for processing the workpiece;

[0045] 2) Machining center status check information: After the machining center receives a machining task, the verification personnel (o2), equipment (k0) and tools are in a ready state, and the machining center (m0) is in a normal state and can complete the next machining task;

[0046] 3) Processing Resource Verification Information: The processing center (m0) acquires tag information for personnel (o2), equipment (k0), and tools involved in processing workpieces via RFID. A trigger command is then used to verify the information on the tags and in the standard operating instructions. If the two sets of information match, processing can proceed.

[0047] 4) Machining Center Task Completion Information: Workpiece (q0), personnel (o2), equipment (k0), tools, and operating instructions are ready. Machining task begins. The part begins machining. The machining output area (p0) of the machining center (m0) is checked to ensure there is workpiece storage space. The workpiece (q0) is moved to the machining output area (p1) of the machining center. The number of workpieces in the machining output area (p0) decreases by 1, and the number of workpieces stored in the machining output area (p1) increases by 1.

[0048] 5) Processing equipment maintenance information: If a malfunction occurs during the processing of the machining center, the tools and equipment need to be maintained regularly.

[0049] The Petri net model of the wire-controlled equipment assembly unit established in step 3 is implemented as follows:

[0050] 1) Obtaining complex product handling information using wired control equipment: Tag information for complex product workpieces (q) is set, and the tag information of the complex product (q) is obtained through the RFID configured on the wired control equipment (t0, t1). The complex product workpiece (q) is marked as awaiting handling, and the handling path (w) of the complex product is obtained;

[0051] 2) Check the status information of the wired control equipment: During the handling of complex products, check whether the wired control equipment is in a ready state, that is, whether it can complete the task of handling the workpiece. If the warning light is not lit, it indicates that the handling equipment is in a ready state and can perform the task of handling the workpiece;

[0052] 3) Workpiece handling information of wire-controlled equipment: Resources such as complex products (q), wire-controlled equipment (t0, t1), and wire-controlled path information (r) are all in a ready state and are ready for handling activities. When a workpiece is transported, the number of workpieces in the assembly input area (s0) decreases by 1, and the number of workpieces in the assembly output area (s1) increases by 1;

[0053] 4) Workpiece storage information and workpiece handling completion information: Determine the availability of space in the assembly input area (s0) or assembly output area (s1) of the assembly center. Handling begins. When a workpiece is moved to the assembly input area (s0), the number of workpieces in the assembly output area (s1) increases by 1, and the storage space in the assembly output area (s1) decreases by 1 workpiece. The wired control equipment completes the handling of workpiece (q0) according to the handling path, and the electronic tag information for the next workpiece (q1) is marked.

[0054] 5) Maintenance information for wired control equipment: After a certain running time (h), the wired control equipment (t0, t1) shall be inspected and maintained in accordance with the maintenance standards for wired control equipment.

[0055] The Petri net model of the assembly completion area established in step 3 is implemented as follows:

[0056] Available storage space information: When the RFID sensor of the handling equipment (w2) detects that there is storage space for workpieces in the assembly completion area (c1), the handling equipment (w2) will transfer the workpieces in the assembly output area (s1), that is, the assembly completion area is in a state of available storage space.

[0057] By real-time sensing of resources such as assembly center wire-controlled equipment and personnel, real-time data on the assembly resources of wire-controlled equipment (t0, t1) is obtained, and equipment sensing is performed by calling the standard operating procedure (SOP) for complex product workpieces (q0). For example, the assembly time is set to 1 hour when both wire-controlled devices are functioning normally; 2 hours when only one wire-controlled device is functioning normally; and 3 hours when neither device is functioning normally. When the plan requires the assembly center to complete the assembly in less than 1 hour, it can only be completed when both devices are functioning normally; when the plan requires the assembly center to complete the assembly in less than 2 hours, it can be completed normally as long as one device is functioning normally, and the remaining wire-controlled device can enter the assembly input area to await new tasks. When no device is functioning normally, the assembly plan must be re-edited. In summary, this embodiment can improve the efficiency and quality of complex product manufacturing units and reduce the waste of human and material resources.
