[0024] To address the issues of high time and cost associated with changeover in existing technologies, this application provides a process control method based on parametric programming. As an optional implementation, this parametric programming-based process control method can be applied, but is not limited to, to processes such as... Figure 1The illustrated process manufacturing system consists of terminal device 102 and server 104, based on parametric programming. For example... Figure 1 As shown, terminal device 102 is connected to server 104 via network 110. Network 110 may include, but is not limited to, wired networks and wireless networks. The wired network includes local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs). The wireless network includes Bluetooth, Wi-Fi, and other networks that enable wireless communication. Terminal device 102 may include, but is not limited to, at least one of the following: mobile phones (such as Android phones, iOS phones, etc.), laptops, tablets, handheld computers, MIDs (Mobile Internet Devices), tablets, desktop computers, smart TVs, etc.

[0025] The aforementioned terminal device 102 is also equipped with a display 106, a processor 108, and a memory 112. The display 106 can be used to display the process processing area, the processor 108 can be used to process the reference processing trajectory, and the memory 112 can be used to store various models and data involved in this application.

[0026] The aforementioned server 104 can be a single server, a server cluster consisting of multiple servers, or a cloud server. The aforementioned server 104 includes a database 114 and a processing engine 116. The database 114 can be used to store various models and data involved in this application, and the processing engine 116 is used to process data such as target machining trajectories corresponding to the various target workpieces.

[0027] According to one aspect of the present invention, the above-described process machining system based on parametric programming can further perform the following steps: First, the terminal device 102 executes S102, sending a process machining request to the server 104 via the network 110; then the server 104 executes S104 to S110: obtaining the target size set, the target workpiece model, and the reference machining trajectory corresponding to the target workpiece; obtaining a parametric template based on the target workpiece model, the parametric template being used to indicate the correspondence between multiple target sizes included in the target size set; revising the reference machining trajectory based on the target size set and the parametric template to obtain the target machining trajectory corresponding to the target workpiece; and performing process machining on the target workpiece based on the target machining trajectory.

[0028] In the above embodiments of the present invention, the above-mentioned process method based on parametric programming solves the problem of high time and cost of production changeover in the prior art, shortens the total time of production changeover debugging, and improves the efficiency of production changeover.

[0029] The above is merely an example, and no limitations are made in this embodiment.

[0030] As an alternative implementation method, please refer to Figure 2 This document illustrates a flowchart of a process fabrication method based on parametric programming, provided in one embodiment of this application. The execution entity for each step of this method can be the terminal device and server described above. In the following method embodiments, for ease of description, the execution entity for each step will only be described as a "computer device." This method may include at least one of the following steps (S202 to S208): S202, Obtain the target size set, target workpiece model and reference machining trajectory corresponding to the target workpiece; S204, Obtain a parameterized template based on the target workpiece model. The parameterized template is used to indicate the correspondence between multiple target dimensions included in the target size set. S206, Based on the target size set, the reference machining trajectory is revised according to the parameterized template to obtain the target machining trajectory corresponding to the target workpiece; S208, perform process machining on the target workpiece based on the target machining trajectory.

[0031] It should be noted that in S202 above, the target size set refers to the summary of all key dimensional parameters of the specific workpiece to be processed. For example, the length of the block base (target workpiece) is 30mm, the width is 20mm, and the height is 25mm. The target workpiece model mentioned above is used to uniquely refer to a series of workpieces with the same topology but different dimensions, and does not include specific dimensions. For example, "block base-02 model" means that the block bases of this model have the same shape but may differ in size. The reference machining trajectory refers to the machining trajectory pre-programmed for a reference workpiece model of a certain model.

[0032] In S204 above, the parameterized template is used to indicate the correspondence between multiple target dimensions included in the target dimension set. For example, the height of the block base of model 02 = the length of the long side of the bottom surface - the length of the short side of the bottom surface. In S206 above, the process of revising the reference machining trajectory according to the parameterized template can be understood as revising the reference machining trajectory corresponding to the reference workpiece model to the target machining trajectory corresponding to the target workpiece (which has the same structure as the reference workpiece model but different dimensions) according to the correspondence between the target dimensions. In S208 above, the process of performing process machining on the target workpiece based on the target machining trajectory includes, but is not limited to: generating a target machining program based on the target machining trajectory; controlling the field equipment to perform process machining on the target workpiece based on the target machining program, and the specific processing technology includes, but is not limited to, welding, spraying, sandblasting, grinding, measurement, and gluing.

[0033] Through the above-described embodiments of this application, the above-described process method based on parametric programming solves the problem of high time and cost of production changeover in the prior art, shortens the total time for production changeover debugging, and improves the efficiency of production changeover.

[0034] As an optional implementation, the above-mentioned method, based on a set of target dimensions, modifies the reference machining trajectory according to a parameterized template to obtain the target machining trajectory corresponding to the target workpiece, including: S1, Establish the target coordinate system corresponding to the target workpiece based on the coordinate system establishment rules; S2, based on the target workpiece model, obtain the reference coordinate system and reference machining trajectory corresponding to the reference workpiece model from the preset storage location, as well as the reference size set corresponding to the reference workpiece; S3, Based on the parameterized template and the reference coordinate system, determine the reference correspondence between the reference machining trajectory and the reference size set and the reference coordinate system; S4. Determine the target correspondence relationship corresponding to the target workpiece based on the reference correspondence relationship, the target coordinate system, and the target size set. S5. Based on the target correspondence, the reference processing trajectory is revised to obtain the target processing trajectory.

[0035] In S1 above, the coordinate system establishment rule is a predefined rule for establishing the target coordinate system. For example, the coordinate system establishment rule is as follows: the point on the back side of the bottom surface of the target workpiece, closest to the machine tool entrance, is taken as the origin of the coordinate system; the positive x-axis direction is determined by pointing from the origin to the point on the back side of the bottom surface of the target workpiece, furthest from the machine tool entrance; the positive y-axis direction is determined by pointing from the origin to the front side of the bottom surface of the target workpiece, closest to the machine tool entrance; the z-axis is obtained by cross-product of the x-axis and y-axis using the "right-hand rule". The target coordinate system corresponding to the target workpiece can be determined by using this coordinate system establishment rule.

[0036] In S2 above, the reference workpiece model corresponds to the target workpiece model, the reference coordinate system is established in the same way as the target coordinate system, the reference machining trajectory is a machining trajectory established for the reference workpiece based on the reference coordinate system, and the reference dimension set refers to the summary of all key dimension parameters of the reference workpiece. The key dimension parameters in the reference dimension set correspond to the key dimension parameters in the target dimension set.

[0037] In S3 above, the reference correspondence between the reference machining trajectory and the reference size set and the reference coordinate system means that the coordinate values ​​of each point on the reference machining trajectory are defined based on the size set of the reference workpiece and the reference coordinate system.

[0038] In S4 above, the process of determining the target correspondence of the target workpiece can be understood as the correspondence between the target size set of the target workpiece, the target coordinate system and the target machining trajectory. In S5 above, the process of revising the reference machining trajectory is to map each point on the reference trajectory to the coordinate system of the target workpiece through a transformation process, so as to obtain the target machining trajectory.

[0039] like Figures 3a-3b As shown, firstly, with point O as the origin, a target coordinate system corresponding to the target workpiece 100 to be welded is established. Based on the model of the target workpiece 100, the reference coordinate system and reference machining trajectory corresponding to the reference workpiece model are obtained, as well as the reference dimension set corresponding to the reference workpiece. Based on the parameterized definition of the geometric features of the target workpiece, a parameterized template can be obtained. The parameterized template represents the correspondence between the total dimension and trajectory point offset angle between the coordinate origin and the machining trajectory, and multiple (at least one) target dimensions and their corresponding offset angles between the coordinate origin and the machining trajectory. Figure 3b Taking the top plate 200 of the target workpiece as an example, let H1 be the distance OA from the origin O to the center A on the left side of the circle, and let the radius of circle A be... The distance from the origin O to the center E of the right reinforcing rib is H2, and the radius EF of the arc at the reinforcing rib is R2. The edge of the top plate 200 and the right arc are both welding trajectories. The angle between the line connecting point C on the edge of the top plate 200 and point A and the extension of OA is an acute angle. The angle between the line connecting point F and point E on the right arc and the extension of line OE is an acute angle. The positions of trajectory point C on the left edge of the top plate 200 and trajectory point F on the right arc can be calculated using reference dimensions H1, H2, R1, R2 and the offset angles of points A, C, E, and F. The position of trajectory point C can be expressed by the formula: ; ; The position of point F on the trajectory of the right-hand arc can be expressed by the formula: ; , By analogy, a parametric template for the target workpiece can be obtained. Using the parametric template, the welding trajectory can be expressed by a parametric formula. Based on the parametric template and the reference coordinate system, the reference correspondence between the reference machining trajectory, the reference size set, and the reference coordinate system can be determined. Then, based on the reference correspondence, the target coordinate system, and the target size set, the target correspondence for the target workpiece can be determined. In other words, when the size changes, the operator only needs to input different values ​​for the corresponding parameters. The system can find the positional relationship between the center of the circle and the coordinate point through geometric relationships, revise the reference machining trajectory based on the target correspondence, and automatically scale the trajectory; there is no need to program the trajectory separately.

[0040] The welding process for target workpiece 100 specifically includes: 1. Spot welding of the main stiffening plate and the outer ring: Taking a dumbbell shape as an example, the process engineer builds a template using software for the first workpiece's parametric programming template: welding is performed between the ring and the main stiffening plate; 2. The main stiffening plate is reversed, and then the stiffening rib is visually grasped and placed in a fixed position; spot welding of the stiffening plate is performed. At this time, the position of the stiffening plate and the position of the weld point will be determined according to different dimensional formulas, such as... Figure 3a1. **Stiffener welding:** During stiffener welding, two welding points are located at the arc of the stiffener, where the length of the stiffener is H + R2. Simultaneously, two welding points are located at the center of the stiffener plate, one above and one below, with a length of R2 radius. Similarly, other welding points for the stiffener on the main stiffener plate can be obtained. 2. **Stiffener plate welding:** The stiffener plate is transported to the stiffener plate by a transport robot, and welding is performed at two fixed points on the bottom of the stiffener plate. These two welding points have coordinate positions within the entire scene, which can be obtained through coordinate transformation. Subsequent parametric trajectory generation is then based on these positions. 3. **Base plate and cover plate welding:** The base plate and cover plate are transported to the already welded main stiffener plate and placed on the left and right sides. They first contact each other through the stiffener plate, and then are directly welded at the contact points between the stiffener plate and the base / cover plate, forming a weld seam. Partial spot welding is performed on the bottom surfaces of the base and cover plates. The spot weld positions are recorded, and subsequent automatic trajectory offset is performed based on parametric dimensions. 5. Following steps 1.2, complete the welding of the upper stiffening plate assembly. In this step, move the assembly to the upper part for welding. This welding includes full welding and requires adding welding trajectories at all bevel positions to ensure the entire small connecting rod can be welded. The full welding trajectory can also be parameterized, and the trajectory will be automatically offset according to the size of the model later. 6. Side plate splicing process: After grabbing the side plate, place it on a fixed right-angle fixture. Then, using the corner point of the fixture as the origin coordinate, weld the long stiffening plate on the side plate according to the size of the side plate. This ensures that the position of the long stiffening plate is consistent with the position of the side plate, and also ensures the position of the subsequent side stiffening plate. 7. Place the two side plates on the base plate according to the dimensions, and then perform spot welding of the welding trajectory. The positions of the two side plates are calculated based on the long stiffening plate. Subsequent dimensional changes will also be based on the calculation results to place the positions of the two side stiffening plates.

[0041] As an optional implementation, the above-mentioned acquisition of the target size set, target workpiece model, and reference machining trajectory corresponding to the target workpiece includes: S1, obtain the login request of the target account, and if the target account meets the preset operation permissions, display the operation interface, which includes the model pre-display sub-interface, the operation sub-interface, and the size display sub-interface; S2, the target workpiece model is determined based on the target account's click operation on the pre-display sub-interface. The operation sub-interface synchronously displays an updated interface including preset size data based on the target workpiece model. The operation sub-interface allows the target account to modify the preset size data. S3, based on the target account's click operation on the update interface, obtains the target size set within the update interface, and retrieves the reference processing trajectory from the preset storage location.

[0042] In step S1 above, the target account refers to the operator account that logs into the parametric programming-based machining system and performs operations. The target account is bound to the operator's identity and permissions. The model pre-display sub-interface is used to display and initially select the workpiece model. The content of the model pre-display sub-interface includes, but is not limited to, a list of all available workpiece models, a thumbnail or brief description of each workpiece model. The operation sub-interface can interact with the operator and is used to display an updated interface including preset dimension data. The dimension display sub-interface is used to automatically update and display the target dimension information corresponding to the target workpiece based on the target workpiece model and modification operations. The display format includes, but is not limited to, a two-dimensional schematic diagram, a read-only data table, and a 3D model view.

[0043] In step S2 above, the operator clicks to confirm the target workpiece model in the pre-display sub-interface, and can modify the preset size data of the target workpiece model in the operation sub-interface. The preset storage location in step S3 above includes, but is not limited to, local server, database, and cloud storage.

[0044] As an optional implementation, the above-mentioned process manufacturing method based on parametric programming further includes: S210: During the process of controlling the field equipment to process the target workpiece, the processing operation information is acquired, including equipment operating parameters, process execution status and task flow signals. S220 monitors the process based on equipment operating parameters, process execution status, and task flow signals; S230 sends an error message when it detects abnormal information in the processing operation information.

[0045] In steps S210-S230 above, the equipment operating parameters are typically precisely controlled by a CNC system or PLC (Programmable Logic Controller), directly determining the output capacity and processing effect of the field equipment. Examples include welding torch temperature, motor current, and the real-time coordinate position of each motion axis. The process execution status can be understood as "what the field equipment is doing," including but not limited to operating status and program segments, such as normal operation, fault, or currently performing welding on the outer diameter of the target workpiece. Task flow signals are instructions or signals used to control the start, pause, and stop of the entire processing task flow, such as start signal, pause signal, and end signal. Abnormal information in the above processing operation information includes, but is not limited to, abnormal situations in assembly and welding, such as abnormal speed or temperature. The steps S210-S230 above can be understood as "acquiring information - real-time monitoring - anomaly warning". These three steps constitute a complete closed loop of real-time monitoring and anomaly handling, which can realize the automatic capture of abnormal information and multi-level warning, enabling management to quickly locate the source of the fault. At the same time, the full process record of abnormal events (occurrence time, scope of impact) can provide data support for process optimization, equipment maintenance strategies and management process improvement, effectively improving the reliability, continuity and intelligent control level of production.

[0046] As an optional implementation, before obtaining the target size set, target workpiece model, and reference machining trajectory corresponding to the target workpiece, the following steps are also included: S1, obtain the login request corresponding to the reference account, and display the programming interface in the offline programming system if the reference account meets the preset programming permissions. The programming interface includes a scene building sub-interface. S2, obtain the reference workpiece model and reference processing technology corresponding to the reference workpiece carried in the login request; S3 builds a simulated process scenario based on the reference workpiece model, reference processing technology, and the click and drag operations of the reference account. S4. Import the reference workpiece model corresponding to the reference workpiece into the simulation process scenario, and generate a reference machining trajectory based on the reference workpiece model using the trajectory generation function in the offline programming system. Then, store the reference machining trajectory and the reference workpiece model in the preset storage location.

[0047] The programming interface in step S1 above is the main operating platform of this parametric programming-based machining system. The programming interface includes, but is not limited to, a scene building sub-interface, a program editing sub-interface, and a simulation control sub-interface. In step S2 above, obtaining the reference workpiece model and reference machining process is used to determine the machining target and machining method. In step S3 above, the simulated process scene refers to a 1:1 virtual scene built in the software that incorporates process-related elements (such as machine tools, robots, positioners, welding torches, and conveyor devices), ensuring consistency with the real scene, and is used for program simulation and verification.

[0048] In step S4 above, the 3D reference workpiece model can be input into the software using the software's input function. Then, it is positioned according to the real scene to ensure consistency with the real scene. At the same time, non-standard equipment in the scene is defined, including positioners, tooling fixtures, welding guns, and other equipment in the scene. This ensures that the scene attributes in the software are consistent with the attributes of the real scene, making the entire processing scene a unified whole. The scene is also calibrated, which includes two parts: first, the calibration of the tooling fixtures, and second, the TCP calibration of the robot. After calibration, the consistency of the relative positional relationship between the scene in the software and the real scene can be guaranteed.

[0049] The specific methods for generating reference machining trajectories based on a reference workpiece model using the trajectory generation function in an offline programming system include, but are not limited to: establishing a reference coordinate system on the reference workpiece model based on preset coordinate system establishment rules; setting a set of reference parameters required for generating the reference machining trajectory based on parameter setting trigger operations in the programming interface based on the reference account; generating the reference machining trajectory using the trajectory generation function based on the reference parameter set and the reference coordinate system; and storing the reference coordinate system in a preset storage location corresponding to the reference workpiece model. The trajectory generation includes the gantry transport trajectory and the robot's machining trajectory, etc.; the offline programming system used to generate the reference machining trajectory includes, but is not limited to, software systems such as SiemensNX, Mastercam, and PTC Creo. These software systems have machining process packages that can generate trajectories based on the welding scenario on-site. Trajectory generation requires setting parameters, including machining angle, distance, machining speed, step size, etc. After setting the parameters, selecting the corresponding weld seam, and then confirming, the welding trajectory can be automatically generated. After generating the reference machining trajectory, the method further includes: generating a reference parameterized template corresponding to the reference workpiece based on the reference parameter set, the reference coordinate system, and the reference machining trajectory; and storing the reference parameterized template in a preset storage location corresponding to the reference workpiece model.

[0050] The parametric programming process of the software includes: setting parameters for the workpiece according to the characteristics of the product model within the software, facilitating subsequent operation by operators. The main function is to parameterize the workpiece, allowing different trajectories to be executed based on different data. Specifically, the entire parametric programming process is divided into two parts: one part is the programming portion for process engineers, and the other part is the application portion for operators.

[0051] In the early stages, process engineers can conveniently use the drag-and-drop operation of the 3D ball and various calibration methods to ensure that the spatial positional relationships between the robot, tools, and machined parts remain consistent in both the design and actual machine environments, achieving high-precision calibration and thus ensuring the accuracy of the operation. Based on importing the CAD model of the connecting rod workpiece into the offline programming software, and according to different specifications and models of connecting rods, the system's welding process library, AUTOPATH function, program editing function, and post-output program functions are used to create corresponding welding trajectories. The position and dimensional parameters of the welding trajectory are recorded. Based on the recorded parameter information, corresponding parametric templates are created according to the corresponding length, width, height, and hole diameter, and the parametric templates are stored in the program management system. Then, the production line operator uses the parametric programming-based process processing system to connect with the information system to obtain the model and size information of the workpiece. They select the corresponding parameter templates stored in the program management system and quickly modify and generate a new trajectory program based on the workpiece's material, length, width, height, and other dimensional information. The automatic assembly and welding parametric programming system can remotely send the modified program file to the field hardware equipment. The industrial gateway collects data information from the field equipment and displays the data information in real time on the data dashboard, facilitating the monitoring of the field equipment's real-time data information.

[0052] In the above embodiments of the present invention, the above-mentioned process method based on parametric programming solves the problem of high time and cost of production changeover in the prior art, shortens the total time of production changeover debugging, and improves the efficiency of production changeover.

[0053] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, because according to the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.

[0054] According to another aspect of the present invention, a process system for implementing the above-described parametric programming-based machining method is also provided, such as... Figure 4 As shown, the system includes: The first acquisition unit 402 is used to acquire the target size set, target workpiece model and reference machining trajectory corresponding to the target workpiece; The second acquisition unit 404 is used to acquire a parameterized template based on the target workpiece model. The parameterized template is used to indicate the correspondence between multiple target dimensions included in the target size set. The revision unit 406 is used to revise the reference machining trajectory based on the target size set and the parameterized template to obtain the target machining trajectory corresponding to the target workpiece. The process processing unit 408 is used to perform process processing on the target workpiece based on the target processing trajectory.

[0055] The aforementioned parametric programming-based process control system collects all necessary variables from the field through data acquisition equipment. This equipment supports PROFINET protocol communication, as well as other common acquisition protocols such as MODBUS, MQTT, and TCP to meet equipment data acquisition requirements. The equipment can collect data on equipment operating status, production data, and fault information. During the execution of the production plan, the system receives work orders through MES or MOM, then initiates the process using the parametric programming-based process control system. It meticulously records data on the processing of the target workpiece, including start and end times of each process step, as well as key parameters (such as welding voltage and current). The work orders received also include the materials required for the production of the connecting rod, process information, and a Bill of Materials (BOM), providing reliable support to production operators.

[0056] The aforementioned parametric programming-based process control system also includes a full-process control system for quality traceability and management: from the moment materials enter the warehouse, it records the batch number and inspection report of the process materials (such as welding wire and base material), linking them to the process work order. During processing, data such as equipment parameters, operators, and processing time are uploaded in real time through workstation barcode scanning. Each processing step is marked with a unique traceability code, and the results of appearance inspection and non-destructive testing are stored simultaneously. When defective products are found, the traceability code can be used to reverse-engineer the relevant material batches, equipment status, and operation records to pinpoint the problem area. A quality archive database is established to regularly analyze defect rates and common defect types, and to optimize processing techniques or personnel training accordingly. At the same time, it ensures that traceability information can be retrieved at any time, meeting the needs of internal review and enabling rapid location and continuous improvement of quality problems. Meanwhile, the parametric programming-based process control system monitors the automated warehouse and line-side warehouse in the production line in real time. It can monitor warehouse location information in a visual way, and the information on outbound location can also monitor the location and status of workpieces at all workstations and warehouses, with real-time dynamic data updates, ensuring visualized management of materials throughout the entire production process.

[0057] In addition, the deep integration of the aforementioned parametric programming-based process control system, through standardized interface configuration, allows for the retrieval of work order data from other systems, including core information such as product model, production quantity, and delivery node, ensuring accurate production planning at the source. It can also obtain real-time material inventory levels, batch codes, and storage location information via the interface, automatically triggering ANDON alerts when materials are insufficient, ensuring a smooth supply chain. Two-way interaction is established with the parametric programming-based process control system, enabling one-click access to the latest process parameters, work instructions, and design drawings, while simultaneously uploading on-site process optimization suggestions, forming a closed-loop process iteration system. Furthermore, the system supports uploading processing data and inspection results to the quality traceability platform, achieving full-process data traceability. Through seamless data flow across multiple systems, information silos are eliminated, manual intervention is reduced, and the efficiency and responsiveness of digital management of process control are improved.

[0058] The core idea of ​​the above-mentioned parametric programming-based machining system is to dynamically adjust the program behavior through external input parameters. The system creates corresponding parametric templates by recording parametric information such as the length, width, and height of the workpiece. It automatically selects the appropriate templates using an information system, obtains the corresponding parameter information such as the length, width, and height of the workpiece, and modifies the template trajectory based on the parameter information. The system remotely sends the program to the field equipment using an automatic assembly and welding parametric programming system, and can monitor the data information status in real time, achieving the integrated effect of parameter programming, control sending, and real-time monitoring.
