[0001] This invention relates to the field of laser cutting technology, and in particular to an embedded laser cutting system and method with processing traceability function. Background Technology

[0002] With the widespread application of laser cutting equipment in industries such as flexible materials and sheet materials, the number of such devices is constantly increasing. Traditional laser cutting equipment mostly relies on offline control modules, which require centralized control via industrial PCs. This results in poor system scalability and makes it difficult to perform refined traceability management of the single-board processing process.

[0003] Because the offline control module lacks an operating system and data management capabilities, it cannot reliably save processing records for a long time, making it difficult for the existing system to meet the needs of quality traceability and equipment anomaly location. Summary of the Invention

[0004] Therefore, it is necessary to provide an embedded laser cutting system and method with processing traceability function to address the above problems.

[0005] An embedded laser cutting system with processing traceability function includes an industrial control computer, a laser machine, a control module, and a data management module. The laser machine includes a machine base, a robotic arm, and a laser head, with the robotic arm slidably mounted on the machine base. The industrial control computer, the laser machine, and the data management module are all signal-connected to the control module. The control module and the laser head are both mounted on the robotic arm. The control module receives signals from the industrial control computer and is responsible for the operation of the laser head and the robotic arm, as well as generating unique identification information. There are multiple robotic arms, control modules, and laser heads, each corresponding to a specific laser head. The industrial control computer issues processing tasks to multiple control modules and obtains the operating status of each laser machine. The data management module stores and manages processing traceability information.

[0006] In one embodiment, the identification information includes device number, system time, and order information.

[0007] In one embodiment, the identification information is presented in the form of a QR code or a serial number; after each identification process is completed, the control module automatically updates the identification information to ensure that unique identification information is generated.

[0008] In one embodiment, the control module includes a PCB board, a processor, and a control connector. The PCB board and the processor are both installed inside the robotic arm. The processor and the control connector are both electrically connected to the PCB board.

[0010] In one embodiment, a time management module is also included, which is used to provide a stable time reference; the time management module is signal-connected to the control module.

[0011] An embedded laser cutting method with processing traceability function, based on the aforementioned embedded laser cutting system with processing traceability function, comprises the following steps: Obtaining processing information: The workpiece to be processed is placed on the machine tool, and multiple Mark points are preset at key positions on the workpiece; the control module obtains the image to be cut, the original cutting path, and the marking information; Path correction: The industrial control computer sends processing tasks to one or more control modules simultaneously. The camera corresponding to each control module captures images of the workpiece to be processed.

Based on the coordinate transformation results, the original cutting path is corrected. Cutting process: The control module controls the laser head to process according to the corrected cutting path; Marking processing: The control module controls the laser head to process the cut workpiece according to the marking information; moreover, the control module automatically updates the marking information after each marking processing is completed. Traceability Information Management: After each processing is completed, the data management module automatically stores and manages the processing traceability information.

[0012] In one embodiment, during the cutting process, the camera periodically acquires images of the workpiece, the control module performs image recognition and feature extraction on the Mark points to obtain the actual spatial coordinates of the Mark points; the control module matches the recognized Mark point coordinates with the previously corrected Mark point coordinates, calculates the overall coordinate transformation matrix, and generates the edge-following compensation amount in real time; the control module dynamically corrects the cutting path of the laser head based on the edge-following compensation amount.

[0023] Please refer to Figure 1 An embedded laser cutting system 100 with processing traceability function according to one embodiment of the invention includes an industrial control computer 10, a laser machine 20, a control module 30, and a data management module 40. The laser machine 20 includes a machine base 21, a robotic arm 22, and a laser head 23. The robotic arm 22 is slidably mounted on the machine base 21. The industrial control computer 10, the laser machine 20, and the data management module 40 are all signal-connected to the control module 30. The control module 30 and the laser head 23 are both mounted on the robotic arm 22. The control module 30 is used to receive signals from the industrial control computer 10, and the operation of the laser head 23 and the robotic arm 22 generates unique identification information. There are multiple robotic arms 22, control modules 30, and laser heads 23, and they correspond one-to-one. The industrial control computer 10 is used to issue processing tasks to multiple control modules 30 and obtain the operating status of each laser machine 20. The data management module 40 is used to store and manage processing traceability information. This embedded laser cutting system 100, equipped with processing traceability, sends processing tasks to multiple control modules 30 and obtains the operating status of each laser machine 20 through an industrial control computer 10. The control modules 30 independently control the operation of the laser head 23 and the robotic arm 22, reducing dependence on the industrial control computer 10. Each control module 30 is independent of each other, has high stability, and a single machine failure does not affect the overall operation. The control modules 30 generate identification information, and the data management module 40 stores and manages the processing traceability information, which facilitates accurate traceability management and reduces the cost of anomaly investigation.

[0024] like Figure 1As shown, in this embodiment, the laser machine 20 includes a machine base 21, a robotic arm 22, and a laser head 23. The robotic arm 22 is slidably mounted on the machine base 21. The industrial control computer 10, the laser machine 20, and the data management module 40 are all signal-connected to the control module 30. The control module 30 and the laser head 23 are both mounted on the robotic arm 22. The control module 30 is used to receive signals from the industrial control computer 10, and is used to independently control the operation of the laser head 23 and the robotic arm 22 and generate unique identification information. There are multiple robotic arms 22, control modules 30, and laser heads 23, and they correspond one-to-one. The industrial control computer 10 is used to issue processing tasks to multiple control modules 30 and obtain the operating status of each laser machine 20. The data management module 40 is used to store and manage processing traceability information. Optionally, each robotic arm 21 is slidably mounted on the same machine base 21; in other embodiments, the machine base 21 and the robotic arm 22 correspond one-to-one.

[0025] In one embodiment, the control module 30 includes a PCB board, a processor, and a control connector. Both the PCB board and the processor are mounted within the robotic arm 22. The processor and the control connector are electrically connected to the PCB board. The industrial computer 10, the laser head 23, and the data management module 40 are all signal-connected to the processor. The control connector is used to electrically connect the processor to a signal transmission unit. Optionally, the processor is a Linux controller; in other embodiments, the processor is a controller such as HarmonyOS. Further, the control connector is a network cable terminal or a USB terminal, connected to the host computer via a network cable, or connected to a USB flash drive via a USB terminal. The industrial control computer 10 edits the graphic to be cut and the marking information to generate the original cutting path, and then transmits the above information to the processor via the network; or, the information is transmitted through the signal connection of the control module 30 through the storage unit storing the cutting image, the original cutting path and the marking information, so that the industrial control computer 10 is not required and offline operation is achieved; furthermore, the storage unit is a USB flash drive or MES subsystem, which receives and parses order data, generates cutting parameters and laser machine 20 control instructions, and sends them to the laser machine 20, while detecting the status of the laser machine 20.

[0026] In one embodiment, the identification information includes the device number, system time, and order information. Optionally, the identification information is presented in the form of a QR code or a serial number. After each identification process is completed, the control module 30 automatically updates the identification information to ensure that unique identification information is generated. For example, when presented in the form of a serial number, after each identification process is completed, the serial number is automatically numbered in sequence, which can distinguish different workpieces and count the quantity.

[0027] In one embodiment, the laser machine 20 further includes a camera 24, which is mounted on the robotic arm 22 and is signal-connected to the processor. The camera 24 is used to acquire the Mark points and image information of the workpiece to be processed. The processor is used to identify the Mark points, calculate the edge-following compensation amount, and dynamically correct the cutting path of the laser head 23 according to the edge-following compensation amount.

[0028] In one embodiment, the embedded laser cutting system 100 with processing traceability function further includes a time management module 50, which is used to provide a stable time reference; the time management module 50 is signal-connected to the control module 30.

[0029] In use, the workpiece to be processed is placed on the machine tool 21, and multiple Mark points are preset at key positions on the workpiece. The control module 30 acquires the image to be cut, the original cutting path, and the marking information. Then, the industrial computer 10 sends the processing task to one or multiple control modules 30 simultaneously. The camera 24 corresponding to the control module 30 captures the image of the workpiece to be processed. The control module 30 performs image recognition and feature extraction on the Mark points to obtain the actual spatial coordinates of the Mark points. The control module 30 matches the recognized Mark point coordinates with the Mark point coordinates in the theoretical model and calculates the overall coordinate transformation matrix. Based on the coordinate transformation results, the original cutting path is initially corrected.

[0030] Next, the control module 30 controls the laser head 23 to perform cutting processing according to the corrected cutting path. During the cutting process, the camera 24 periodically acquires images of the workpiece, and the control module 30 performs image recognition and feature extraction on the Mark points to obtain their actual spatial coordinates. The control module 30 matches the identified Mark point coordinates with the previously corrected Mark point coordinates, calculates the overall coordinate transformation matrix, and generates a real-time edge-following compensation amount. The control module 30 dynamically corrects the cutting path of the laser head 23 based on the edge-following compensation amount. Subsequently, the control module 30 controls the laser head 23 to process the cut workpiece according to the marking information. Furthermore, after each marking processing is completed, the control module 30 automatically updates the marking information. Additionally, after each processing cycle, the data management module 40 automatically stores and manages the processing traceability information.

[0031] This embedded laser cutting system 100, equipped with processing traceability, integrates computing functions through a control module 30, enabling independent control of the laser head 23 and robotic arm 22. This reduces reliance on the industrial control computer 10. Each control module 30 operates independently, ensuring high stability; a single machine failure does not affect the overall operation. Furthermore, visual feedback and robotic arm 22 operation are coordinated in a closed loop, reducing latency and providing strong real-time performance. Additionally, a single industrial control computer 10 can simultaneously control multiple laser machines 20, enabling parallel processing and effectively reducing system management costs while improving overall production efficiency and system reliability. Pre-cutting path correction and dynamic path adjustment during cutting improve positioning accuracy and adapt to material offset and deformation. The control module 30 generates identification information, while the data management module 40 stores and manages processing traceability information. When quality anomalies are detected later, the identification information allows for quick and accurate tracing of the processing time and the laser machine 20, reducing anomaly investigation costs and achieving localization and automation of traceability functionality.

[0032] An embedded laser cutting method with processing traceability function, based on the aforementioned embedded laser cutting system 100 with processing traceability function, comprises the following steps: Acquiring processing information: The workpiece to be processed is placed on the machine tool 21, and multiple Mark points are preset at key positions on the workpiece; the control module 30 acquires the image to be cut, the original cutting path, and the marking information; optionally, in the step of acquiring processing information, the graphic to be cut and the marking information are edited by the industrial control computer 10 to generate the original cutting path; or, the information is transmitted by signaling the control module 30 through the storage unit that stores the cutting image, the original cutting path, and the marking information.

[0033] Path correction: The industrial computer 10 sends processing tasks to one or more control modules 30 simultaneously.

The control module 30 performs image recognition and feature extraction on the Mark points to obtain the actual spatial coordinates of the Mark points. The control module 30 matches the recognized Mark point coordinates with the Mark point coordinates in the theoretical model and calculates the overall coordinate transformation matrix. Based on the coordinate transformation results, the original cutting path is corrected. Cutting Processing: The control module 30 controls the laser head 23 to process according to the corrected cutting path; optionally, in the cutting processing step, the camera 24 periodically acquires images of the workpiece, and the control module 30 performs image recognition and feature extraction on the Mark points to obtain the actual spatial coordinates of the Mark points; the control module 30 matches the recognized Mark point coordinates with the previously corrected Mark point coordinates, calculates the overall coordinate transformation matrix, and generates the edge-following compensation amount in real time; the control module 30 dynamically corrects the cutting path of the laser head 23 according to the edge-following compensation amount.

[0034] Marking processing: The control module 30 controls the laser head 23 to process the cut workpiece according to the marking information; moreover, after each marking processing is completed, the control module 30 automatically updates the marking information; Traceability Information Management: After each processing is completed, the data management module 40 automatically stores and manages the processing traceability information.

[0035] The embedded laser cutting system 100 of the present invention, which has processing traceability function, sends processing tasks to multiple control modules 30 and obtains the operating status of each laser machine 20 through an industrial control computer 10. The control modules 30 independently control the operation of the laser head 23 and the robotic arm 22, reducing the dependence on the industrial control computer 10.
