Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting and flame cutting composite cutting, and in particular to a three-in-one laser flame composite cutting system with dual height tracking. Background Art

[0002] Laser cutting and flame cutting are two common cutting processes widely used in modern industry. In the existing technology, laser cutting and flame cutting are usually operated independently, which means that when the needs of thin plate and thick plate cutting need to be met at the same time, the factory must configure two independent sets of equipment, one for laser cutting and the other for flame cutting. There are several problems with this approach: on the one hand, the company needs to invest a lot of money to purchase and maintain two sets of cutting equipment; on the other hand, the operator needs to be proficient in both cutting methods, which brings additional burdens to production operations and equipment management.

[0003] And the height control system in the prior art is mainly designed for a single cutting method. For example, laser cutting usually relies on high-precision laser sensors to ensure the precise distance between the cutting head and the material surface to ensure that the laser can focus on the correct position. Flame cutting allows a certain height deviation between the cutting head and the material, and the accuracy requirement of the flame sensor is relatively low. However, in the composite cutting process, the cutting head height requirements for laser cutting and flame cutting are completely different. This leads to the fact that in the composite cutting mode, if the system cannot adjust the height of the cutting head in real time during the cutting process, it is easy to cause insufficient cutting accuracy or substandard cutting quality, resulting in the following problems: 1. Existing compound cutting systems still have major problems in height control. Traditional compound cutting equipment cannot effectively coordinate the signals of the laser and flame sensors, making it difficult to achieve precise height adjustment during the cutting process. This not only affects the accuracy of laser focusing, but may also cause the height of the cutting head to be unstable during flame cutting, thus affecting the cutting quality.

[0004] 2. Limitations of height sensing devices: In the prior art, although some devices can be adjusted in height manually or in simple automatic ways, these methods often lack real-time feedback and precise control. Especially in complex compound cutting modes, this lack of precise control of height adjustment often leads to inconsistent cutting quality and may even damage the equipment.

[0005] 3. Insufficient adaptability in compound cutting mode: In compound cutting mode, there is a significant difference in the height requirements of the cutting head between laser and flame cutting. The height control in existing systems often fails to make fine adjustments to this difference, resulting in the difficulty of achieving the expected high precision and high quality requirements in the compound cutting mode. To solve this problem, many existing devices require operators to manually adjust the height control system, which increases the difficulty of operation and may also affect cutting efficiency and safety.

[0006] In order to overcome the above problems, some cutting systems have tried to introduce dual height tracking technology, which provides a precise cutting head height adjustment solution by combining laser and flame sensors. However, the existing dual height tracking technology mostly relies on single sensor feedback, or lacks intelligent adjustment mechanism in sensor signal fusion, resulting in insufficient adaptability and accuracy in practical applications.

[0007] Therefore, how to achieve accurate and real-time adjustment of the cutting head height in the composite cutting mode and coordinate the signals of the laser and flame sensors has become a technical problem to be solved by the present invention. Summary of the invention

[0008] The technical problem solved by the present invention is to provide a three-in-one laser flame composite cutting system with dual height tracking in response to the defects existing in the above-mentioned prior art, so as to solve the problems of inaccurate height control and unstable cutting quality in the composite cutting mode proposed in the above-mentioned background technology.

[0009] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: A three-in-one laser-flame composite cutting system with dual height tracking, the system is equipped with an adaptive switching module based on real-time feedback, a dual height tracking module, a fault self-checking module, an intelligent cutting path optimization module and a data fusion and cloud linkage module, wherein: Adaptive switching module: including a sensor feedback unit and an intelligent switching algorithm unit. The sensor feedback unit is used to monitor the thickness, temperature change, cutting path complexity and cutting quality of the cutting plate in real time. The intelligent switching algorithm unit dynamically selects laser cutting, flame cutting or laser-flame composite cutting mode based on the feedback data to ensure the optimal cutting efficiency and quality under different plate thicknesses and cutting conditions. Dual height tracking module: including high-precision laser sensor and low-precision flame sensor. The laser sensor is used for precise focus control during laser cutting, and the flame sensor is used for maintaining stable height during flame cutting. In the laser-flame composite cutting mode, the dual height tracking module coordinates the laser and flame sensor signals to achieve dynamic adjustment of the cutting head height to ensure laser focusing and cross-sectional smoothness and overall accuracy of flame cutting. Fault self-check module: used to monitor the working status of the laser cutting device and the flame cutting device in real time, detect parameters such as the cutting head temperature, laser power and gas pressure, and automatically trigger switching to a feasible cutting mode when a fault is detected in the laser or flame cutting device, avoiding production interruption and ensuring the continuity of the cutting process; Intelligent cutting path optimization module: used to optimize the cutting path sequence and speed based on the analysis of plate material, cutting path and heat-affected area, avoid thermal stress concentration, reduce material deformation and uneven cutting edges, and automatically avoid a certain area when the temperature reaches a predetermined threshold, and continue cutting after it cools down, thereby improving the smoothness of the cutting edge and the overall cutting quality; Data fusion and cloud linkage module: This module uploads the working parameters of the cutting process to the cloud in real time through cloud backup and data analysis, automatically optimizes the cutting parameters based on big data feedback and historical cutting records, and intelligently recommends the optimal cutting mode and parameter settings based on user usage habits and cutting requirements to improve the intelligence level of the system and user operation experience.

[0010] As a further solution of the present invention, the intelligent switching algorithm unit of the adaptive switching module includes a dynamic analysis algorithm, which automatically identifies the complexity of the cutting path and the thermal sensitivity of the cutting material based on real-time feedback data of the cutting plate, and performs intelligent switching according to material thickness, thermal impact and cutting path to optimize the selection of cutting mode.

[0011] As a further solution of the present invention, the dual height tracking module realizes high-precision focusing control through the laser sensor in the laser cutting mode, and preferentially uses the flame sensor signal to control the cutting head height in the flame cutting mode; in the laser-flame composite cutting mode, the data of the laser and flame sensors are simultaneously collected, and the signal is fused and dynamically adjusted through the control system to ensure that the cutting head is always at the optimal working height.

[0012] As a further solution of the present invention, the fault self-detection module is equipped with a laser power monitor, a gas pressure sensor and a cutting head temperature sensor. The fault self-detection module can monitor the equipment status at each working stage of the cutting process. When abnormal parameters are detected, a fault alarm signal is issued and the cutting mode switching is triggered to ensure the continuity of production and the safety of the equipment.

[0013] As a further solution of the present invention, after fault detection, the fault self-detection module automatically starts a preset emergency cutting mode through the control system, or switches to a semi-automatic or manual operation mode to avoid production stagnation and meet the reliability requirements of different production environments.

[0014] As a further solution of the present invention, the intelligent cutting path optimization module uses a path planning algorithm to dynamically adjust the cutting path based on the cutting sequence and thermal impact analysis to reduce the accumulation of thermal stress; when the system detects that the temperature of the cutting area reaches a predetermined threshold, the intelligent cutting path optimization module automatically re-plans the path to bypass the area, and resumes cutting after it cools down to ensure the consistency of cutting quality.

[0015] As a further solution of the present invention, the intelligent cutting path optimization module automatically adjusts the moving speed of the cutting head on the preset cutting path according to different material properties, thickness and thermal diffusion coefficient, giving priority to ensuring the smoothness of the cutting edge and reducing the risk of material deformation.

[0016] As a further solution of the present invention, the data fusion and cloud linkage module generates and updates the cutting parameter database in the cloud, and automatically optimizes the cutting parameter configuration of the device based on the historical cutting data of the device and the user's operating habits to achieve personalized intelligent recommendation. As a further solution of the present invention, the data fusion and cloud linkage module can recommend to users the best cutting modes and cutting paths suitable for different materials and thicknesses based on the historical data of different users, and allow users to share successful cutting configuration data between different devices to improve cutting quality and production efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Intelligent switching improves cutting efficiency and quality: The adaptive switching module of the present invention can intelligently select the optimal cutting mode (laser cutting, flame cutting or laser-flame composite cutting) according to the real-time feedback of cutting parameters (such as plate thickness, temperature change, cutting path complexity, etc.). This mode switching not only avoids the tediousness of traditional equipment that needs to be configured with laser and flame cutting systems separately, but also enables the system to automatically adjust according to different cutting requirements to achieve the effect of "1+1 is greater than 2". This intelligent switching greatly improves cutting efficiency, especially for scenes with large changes in material thickness or complex cutting paths, and significantly improves cutting quality.

[0018] 2. Dual height tracking ensures cutting accuracy and stability: The dual height tracking technology adopted by the present invention can accurately control the height of the cutting head during laser cutting and flame cutting by combining the signals of high-precision laser sensors and low-precision flame sensors. In the compound cutting mode, the control system automatically coordinates the signals of the two sensors to ensure that the laser focus position and the height of the flame cutting remain stable, which not only ensures the high precision of laser cutting, but also ensures the smooth cross-section of flame cutting. This design greatly improves the cutting quality during the compound cutting process, especially in thick plate cutting and complex paths, reduces cutting errors, and improves the consistency and surface quality of the product.

[0019] 3. Fault self-checking and emergency switching to ensure production continuity: The system's fault self-checking module monitors the working status of the cutting device in real time. When the equipment fails, it can quickly identify the cause of the failure through self-diagnosis and intelligently trigger emergency switching to other cutting modes or manual mode, thereby avoiding stagnation of the production line. This fault self-checking and emergency switching function greatly improves the reliability of the equipment and the stability of production, reduces the loss of production stoppage caused by equipment failure, and ensures the efficient operation of the system in a complex production environment.

[0020] 4. Intelligent path optimization reduces deformation in the heat-affected zone: The intelligent cutting path optimization module automatically adjusts the cutting path and cutting speed by analyzing the heat-affected zone of the cutting material, path complexity and other factors to avoid deformation caused by overheating of the material and poor cutting edge quality. This technology effectively reduces the accumulation of thermal stress and improves the smoothness and precision of the cutting surface, especially in the cutting of large-area thick plates, which has obvious advantages.

[0021] 5. Cloud data fusion optimizes cutting parameters and operating experience: The cloud data fusion and linkage module of the present invention realizes the optimization and personalized recommendation of intelligent cutting parameters by collecting the working data and historical cutting records of the equipment. The cloud platform can automatically adjust the equipment configuration according to the operating habits and production needs of different users, and recommend the optimal cutting mode and cutting path to the user. It not only improves the intelligence level of the system, but also enables users to achieve the optimal cutting effect more conveniently and efficiently during the operation process, thereby improving the overall production efficiency and product quality.

[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1 —3. In an embodiment of the present invention, a three-in-one laser flame composite cutting system with dual height tracking is provided, wherein the system is provided with an adaptive switching module based on real-time feedback, a dual height tracking module, a fault self-checking module, an intelligent cutting path optimization module and a data fusion and cloud linkage module, wherein: Adaptive switching module: including a sensor feedback unit and an intelligent switching algorithm unit. The sensor feedback unit is used to monitor the thickness, temperature change, cutting path complexity and cutting quality of the cutting plate in real time. The intelligent switching algorithm unit dynamically selects laser cutting, flame cutting or laser-flame composite cutting mode based on the feedback data to ensure the optimal cutting efficiency and quality under different plate thicknesses and cutting conditions. Dual height tracking module: including high-precision laser sensor and low-precision flame sensor. The laser sensor is used for precise focus control during laser cutting, and the flame sensor is used for maintaining stable height during flame cutting. In the laser-flame composite cutting mode, the dual height tracking module coordinates the laser and flame sensor signals to achieve dynamic adjustment of the cutting head height to ensure laser focusing and cross-sectional smoothness and overall accuracy of flame cutting. Fault self-check module: used to monitor the working status of the laser cutting device and the flame cutting device in real time, detect parameters such as the cutting head temperature, laser power and gas pressure, and automatically trigger switching to a feasible cutting mode when a fault is detected in the laser or flame cutting device, avoiding production interruption and ensuring the continuity of the cutting process; Intelligent cutting path optimization module: used to optimize the cutting path sequence and speed based on the analysis of plate material, cutting path and heat-affected area, avoid thermal stress concentration, reduce material deformation and uneven cutting edges, and automatically avoid a certain area when the temperature reaches a predetermined threshold, and continue cutting after it cools down, thereby improving the smoothness of the cutting edge and the overall cutting quality; Data fusion and cloud linkage module: This module uploads the working parameters of the cutting process to the cloud in real time through cloud backup and data analysis, automatically optimizes the cutting parameters based on big data feedback and historical cutting records, and intelligently recommends the optimal cutting mode and parameter settings based on user usage habits and cutting requirements to improve the intelligence level of the system and user operation experience.

[0029] Among them, the adaptive switching module is located in the system control core, which is used to analyze and receive real-time feedback signals from each module. It is mainly connected to the dual height tracking module and the intelligent cutting path optimization module, and receives the status signal from the fault self-checking module. The adaptive switching module automatically switches between laser cutting, flame cutting and compound cutting modes according to the real-time feedback data to adapt to different material thicknesses and cutting requirements. The dual height tracking module is installed on the cutting head device, including a high-precision laser sensor and a low-precision flame sensor, which are used for height control during laser and flame cutting respectively. The dual height tracking module feeds back the height information to the adaptive switching module, and dynamically adjusts the cutting head height according to the instructions of the adaptive switching module to ensure the height accuracy and stability in the compound cutting mode. The fault self-checking module is connected to the adaptive switching module and the working parts of the cutting equipment (such as laser source, flame source, cutting head, etc.), and is responsible for real-time monitoring of the working status of each component (such as temperature, laser power and gas pressure, etc.). Once an abnormality is detected, the fault self-checking module will send a fault signal to the adaptive switching module and trigger the system to switch to manual or semi-automatic mode to ensure the continuity of production. The intelligent cutting path optimization module dynamically plans the cutting path and speed according to the thermal diffusion characteristics of the cutting material, the complexity of the path and the cutting requirements. This module works in conjunction with the adaptive switching module to control the motion path of the cutting head in real time, and feeds back the optimized path data to the adaptive switching module to ensure that the cutting process is efficient and the thermal impact is minimized. The data fusion and cloud linkage module is connected to the system control core, and is mainly used to back up the cutting parameters, work records and user operation habits of the equipment in the cloud, and optimize the parameter configuration of the equipment through data analysis. The data fusion module can feed back the optimization results and the user's personalized needs to the adaptive switching module, so that the adaptive switching module can better optimize the cutting mode selection and parameter adjustment in subsequent work.

[0030] As a further solution of the present invention, the intelligent switching algorithm unit of the adaptive switching module includes a dynamic analysis algorithm, which automatically identifies the complexity of the cutting path and the thermal sensitivity of the cutting material based on real-time feedback data of the cutting plate, and performs intelligent switching according to material thickness, thermal impact and cutting path to optimize the selection of cutting mode.

[0031] As a further solution of the present invention, the dual height tracking module realizes high-precision focusing control through the laser sensor in the laser cutting mode, and preferentially uses the flame sensor signal to control the cutting head height in the flame cutting mode; in the laser-flame composite cutting mode, the data of the laser and flame sensors are simultaneously collected, and the signal is fused and dynamically adjusted through the control system to ensure that the cutting head is always at the optimal working height.

[0032] As a further solution of the present invention, the fault self-detection module is equipped with a laser power monitor, a gas pressure sensor and a cutting head temperature sensor. The fault self-detection module can monitor the equipment status at each working stage of the cutting process. When a parameter abnormality is detected, a fault alarm signal is issued and the cutting mode switching is triggered to ensure the continuity of production and the safety of the equipment. After the fault is detected, the fault self-detection module automatically starts the preset emergency cutting mode through the control system, or switches to a semi-automatic or manual operation mode to avoid production stagnation and meet the reliability requirements of different production environments.

[0033] The intelligent cutting path optimization module uses a path planning algorithm to dynamically adjust the cutting path based on the cutting sequence and thermal impact analysis to reduce thermal stress accumulation; when the system detects that the temperature of the cutting area reaches a predetermined threshold, the intelligent cutting path optimization module automatically replans the path to bypass the area and resumes cutting after it cools down to ensure the consistency of cutting quality. The intelligent cutting path optimization module automatically adjusts the moving speed of the cutting head on the preset cutting path according to different material properties, thickness and thermal diffusion coefficient, giving priority to ensuring the smoothness of the cutting edge and reducing the risk of material deformation.

[0034] The present invention is based on the different requirements of laser cutting and flame cutting for the height of the cutting head. For example, laser requires higher precision to focus, while flame cutting allows slight height deviation. In compound cutting, if the height of the cutting head cannot be accurately adjusted in real time, it is likely to lead to poor cutting quality or even equipment damage. On this basis, the dual height tracking system of the present invention includes: 1. A high-precision laser sensor tracks the distance between the cutting head and the surface of the material for laser focusing and perforation; 2. A low-precision, high-durability height sensor adapted for flame cutting to ensure the height of the cutting head during the flame cutting stage. 3. When switched to compound mode, the system can automatically coordinate the signals of the laser and flame sensors, and dynamically adjust the height of the cutting head to ensure that both laser focusing and flame cutting are in the best state.

[0035] The data fusion and cloud linkage module generates and updates the cutting parameter database in the cloud, and automatically optimizes the cutting parameter configuration of the equipment through the historical cutting data of the equipment and the user's operating habits to achieve personalized intelligent recommendation. The data fusion and cloud linkage module can recommend the best cutting mode and cutting path suitable for different materials and thicknesses to users based on the historical data of different users, and allow users to share successful cutting configuration data between different devices to improve cutting quality and production efficiency.

[0036] Embodiment 1: This embodiment introduces a laser flame cutting system for a composite cutting mode, and explains in detail, in combination with specific application scenarios, how to optimize cutting quality and improve cutting efficiency through dual height tracking technology, and solve the problem of inaccurate cutting head height control in the prior art.

[0037] Suppose that in a production workshop, a customer needs to cut a stainless steel plate with a thickness of 20 mm, and the edge of the plate is required to have a smooth cutting surface. The cutting of the plate involves both laser cutting and flame cutting. Since the plate is relatively thick, single laser cutting or flame cutting cannot take into account both cutting efficiency and cutting quality. Therefore, the customer selected the laser-flame composite cutting system provided by the present invention, in order to obtain both the rapid perforation of laser cutting and the smooth cut surface of flame cutting in the composite cutting mode.

[0038] When the system is enabled, laser perforation is performed first. The laser cutting head relies on a high-precision laser sensor to track the distance between the cutting head and the material surface in real time, ensuring that the laser focus point is accurately aligned with the area to be cut, avoiding the phenomenon of laser focus drift during the cutting process. In this process, the height variation range of the laser cutting head is small, and the accuracy requirement is high. This precision control can be adjusted in real time through the feedback signal of the laser sensor to keep the distance between the cutting head and the material surface no more than 0.1mm, thereby ensuring fast and accurate perforation.

[0039] After the laser cutting completes the perforation, the cutting system automatically switches to flame cutting mode. The requirements of the flame cutting stage are different from those of laser cutting, because flame cutting allows a larger deviation between the cutting head and the material surface, and can usually tolerate height fluctuations of up to 2mm. Therefore, this system uses a low-precision, high-durability flame sensor, which can effectively cope with temperature changes and thermal expansion of the workpiece during flame cutting to ensure the stability of the flame cutting head. During this process, the flame sensor provides a signal to the control system to inform the current cutting head height. If the cutting head height deviates from the set range, the system will automatically adjust the cutting head position to maintain the most suitable working height.

[0040] However, in the composite cutting mode, the height adjustment of the cutting head cannot rely solely on a single laser or flame sensor. In order to ensure that the laser cutting and flame cutting can reach the optimal state at the same time during the cutting process, the dual height tracking system of the present invention plays a key role. The system automatically adjusts the height of the cutting head during the switching mode by real-time coordination of the signals of the laser sensor and the flame sensor, ensuring high accuracy during the laser cutting process, while the height fluctuation of the cutting head during the flame cutting process is allowed to be within a certain range, thereby ensuring the stability of the flame cutting.

[0041] For example, during flame cutting, although the signal provided by the laser sensor does not directly adjust the height of the cutting head, the system will dynamically adjust the height of the cutting head according to the data of the flame sensor, and filter the signal of the laser sensor when necessary, so as to achieve the coordinated work of the two sensors and avoid the problem of reduced cutting quality caused by data mismatch between height sensors in traditional systems. The key technology in this process lies in the dynamic coordination and real-time adjustment of the signal, ensuring that the system can meet the high-precision requirements of laser cutting and cope with the wider allowable range of flame cutting, so as to achieve a balance between cutting accuracy and cutting speed in the composite cutting mode.

[0042] In this application scenario, the compound cutting system can effectively solve the height control problem in traditional systems through dual height tracking technology. Specifically, in compound cutting mode, the system can not only automatically coordinate the different requirements of the two cutting modes for the cutting head height, but also adjust the position of the cutting head in real time, avoiding the problems of inconsistent cutting quality or equipment damage caused by height mismatch in traditional technology. This efficient and accurate height adjustment mechanism greatly improves production efficiency while improving cutting quality.

[0043] In addition, the system also has fault self-checking and emergency switching functions. For example, during a certain operation, if the height sensing device fails, the system will automatically identify the problem and trigger the emergency mode, allowing the operator to manually adjust the cutting head height or switch to semi-automatic mode to avoid production interruption. This function further ensures the reliability of the equipment and the continuity of production.

[0044] In summary, this embodiment successfully solves the problems of inaccurate height control and unstable cutting quality in the traditional laser flame composite cutting system by adopting dual height tracking technology, intelligent switching mode and fault self-checking system, which not only improves the cutting efficiency and quality, but also improves the reliability of the equipment and the flexibility of operation. The application of these technologies makes the present invention a significant technological advancement in the field of composite cutting, and meets the urgent needs of the industry for efficient and high-precision cutting.

[0045] Embodiment 2: See also Figure 2 In this embodiment, the laser flame composite cutting system process is described in detail in combination with the drawings provided by the customer, and the specific implementation methods of each step are further demonstrated. In this embodiment, the laser flame composite cutting process includes two main stages: composite perforation stage and composite cutting stage. The specific stages are as follows: 1. Composite perforation stage: After the process starts, the system first enters the compound perforation stage. The system sets the peak power of the laser perforation and sets the appropriate main oxygen pressure and fuel gas pressure according to the properties and thickness of the material. At this time, the main oxygen pressure gradually changes to the creeping starting pressure according to the preset change rate.

[0046] Then, the system adjusts the Z-axis height of the cutting head to the crawling start height, and adjusts the focus position of the laser to ensure that the laser is focused on the predetermined perforation focus position. The focus control at this stage is particularly critical to ensure the perforation speed and accuracy.

[0047] After the Z-axis height and focus position reach the preset values, the system waits for the relevant actions to be in place. If the set timeout period is reached and the conditions are not met, the system will readjust to ensure that the parameters of each part of the system are in the best state before entering the next operation.

[0048] When the action is in place, the system gradually adjusts the Z-axis height to the crawling end height, moves the XY axis a predetermined distance, and adjusts the main oxygen pressure to the perforation end pressure. The system sets the laser duty cycle and frequency and starts the light operation. At this time, the light time is strictly controlled according to the preset to complete the perforation.

[0049] 2. Compound cutting stage, after the compound perforation is completed, the system automatically enters the compound cutting stage. First, the Z-axis height of the cutting head is adjusted to the cutting height to ensure that the distance between the laser and the material surface remains stable during the cutting process.

[0050] The system adjusts the gas pressure to the gas pressure required for the cutting stage, and at the same time adjusts the main oxygen pressure to the gas pressure required for cutting to ensure the stability of the cutting airflow; the preheating pressure is also set to the cutting preheating pressure according to the material and cutting requirements to improve the efficiency of flame cutting.

[0051] Next, the system sets the peak power of the cutting and adjusts the duty cycle and frequency of the laser to start the light operation. At this time, the system controls the XY axis to move along the set cutting trajectory at the predetermined cutting speed to complete the material cutting operation. The selection of the cutting trajectory is based on the shape and complexity of the material to ensure the continuity and stability of the cutting process.

[0052] When the set light output time is reached, the system automatically stops the light output and completes the cutting of the current contour. The system determines whether the contour cutting has been completed. If not, the main oxygen is turned off, the Z axis rises to the lifting height, and moves to the starting point of the next contour during the idle movement to continue the cutting operation.

[0053] 3. Intelligent control of the cutting process. During the entire cutting process, the adaptive switching module, dual height tracking module, fault self-checking module and intelligent cutting path optimization module each play different roles. For example, the adaptive switching module selects appropriate laser and flame parameters in the perforation and cutting stages to ensure the perforation speed and the quality of the cutting section.

[0054] The dual height tracking module adjusts the height of the cutting head in real time, especially when switching from perforation to cutting, ensuring that the height of the cutting head remains optimal in different modes to achieve high-quality cutting results.

[0055] The fault self-diagnosis module monitors parameters such as laser power, oxygen and gas pressure at each stage of the cutting process. If an abnormal situation is detected, the system will automatically adjust or switch modes to ensure the continuity of the production process and the safety of the equipment.

[0056] The intelligent cutting path optimization module adjusts the cutting trajectory during the cutting process, avoids high-heat areas or appropriately reduces the cutting speed to ensure the smoothness of the cutting edge and the integrity of the material.

[0057] Embodiment 3: In this embodiment, specific implementation methods of each module of the present invention in different application scenarios are further described in detail.

[0058] First, during the actual cutting process, the intelligent switching algorithm unit of the adaptive switching module automatically identifies the complexity of the cutting path and the thermal properties of the material through a dynamic analysis algorithm. For example, when cutting thin and uniform steel plates, the system gives priority to the laser cutting mode to improve speed and accuracy. When increased path complexity or uneven material thickness is detected, the algorithm will select flame cutting or compound cutting to avoid insufficient laser perforation or quality degradation during the cutting process. The adaptive switching module realizes automatic adjustment according to the cutting environment based on material properties and thermal feedback to ensure the optimization of cutting quality under different conditions.

[0059] Secondly, in the laser cutting mode, the laser sensor of the dual height tracking module maintains precise control of the distance between the cutting head and the material surface to ensure that the laser can focus accurately. In the flame cutting mode, the system gives priority to the signal of the flame sensor and controls the stability of the cutting head through a wider height tolerance, which is particularly suitable for thick plate cutting. In the composite cutting mode, the system simultaneously collects the height data of the laser and flame sensors. Through signal fusion and dynamic adjustment algorithms, the system automatically adjusts the height of the cutting head to ensure the accuracy of laser perforation and the stability of flame cutting. For example, when cutting a 20mm thick alloy plate, this mode can ensure the compatibility of the laser focus height and the flame height to ensure a smooth cutting edge.

[0060] The fault self-check module is equipped with a laser power monitor, a gas pressure sensor, and a cutting head temperature sensor to ensure the safety and stability of the equipment. For example, during the laser cutting stage, if the laser power monitor detects that the power is low, it may indicate that the laser temperature is too high. The module will trigger an alarm signal and automatically switch to flame cutting mode. During the flame cutting process, if the gas pressure sensor detects that the gas is insufficient, the system will automatically switch to laser cutting mode or suspend cutting to ensure production safety. The module monitors at each stage of cutting to ensure the safety of equipment operation.

[0061] In the event of a fault, the fault self-check module can also start the emergency cutting mode or switch to manual / semi-automatic operation through the control system according to different fault conditions. For example, when it is detected that the laser power drops but the flame device is normal, the module will automatically switch to the flame mode to continue working; if the height sensor is damaged, the system will notify the operator to switch to the manual operation mode to maintain production continuity and cutting accuracy, which is especially suitable for emergency handling in continuous production lines.

[0062] The intelligent cutting path optimization module uses a path planning algorithm to dynamically manage the heat-affected zone. For example, when cutting composite materials with uneven thickness, the module will adjust the path and speed according to the order of different cutting paths and the heat diffusion characteristics to ensure the uniform distribution of thermal stress. In high-temperature areas, the system will automatically delay cutting or avoid the area and resume after cooling to maintain consistent cutting quality. The module can also automatically adjust the moving speed of the cutting head. For example, when cutting highly heat-sensitive materials such as aluminum alloy and copper, the cutting speed can be reduced to reduce material deformation and ensure smooth edges.

[0063] The data fusion and cloud linkage module generates and updates the cutting parameter database in the cloud, and automatically optimizes the cutting parameter configuration by analyzing the user's historical cutting data and operating habits. For example, if it is detected that the user often cuts stainless steel plates and often chooses the composite mode, the module will give priority to recommending the corresponding optimal parameter configuration. The module can also synchronize the user's successful cutting configuration between different devices, so that the operating experience can be shared in the cloud, optimize the cutting effect of different devices, and further improve the cutting quality and production efficiency.

[0064] Embodiment 4: See also Figure 3 This implementation describes in detail the punching execution process of the composite cutting system, and further explains the various operation steps and specific implementation methods in the drawings. In this embodiment, the punching execution process of the composite cutting mainly includes two stages: the slow-start punching stage and the cutting stage. The detailed process of each stage is as follows: 1. Slow start punching stage: The system first enters the slow-start perforation stage and begins to locate to the starting position. At this time, the system adjusts the main oxygen pressure to the crawling starting pressure. The pressure change speed is controlled according to the preset main oxygen change rate to ensure that the pressure rises steadily.

[0065] Then, the height of the Z axis is gradually adjusted to the height where the crawling starts, and the laser focus is adjusted to the preset perforation focus position. The key to this step is to accurately control the height of the cutting head and the focus position of the laser to ensure that the laser can be focused on the area to be cut during perforation, thereby achieving efficient perforation.

[0066] After the focus and height are adjusted, the system enters the action waiting state to ensure that all actions are synchronized in place. This is to avoid errors caused by inaccurate parameters during the cutting process.

[0067] Then, the system moves synchronously along the cutting path for a certain distance at a slow start speed, the main oxygen pressure changes synchronously to the set end pressure, and the Z-axis height is synchronously adjusted to the crawling end height. This synchronous operation ensures the consistency of pressure, focus and height during the perforation process, reducing errors.

[0068] During the perforation process, the system sets the duty cycle and frequency of the laser, starts the light-emitting operation, and sets the peak power of the slow-start knife. At this time, the system maintains a certain light-emitting time to complete the perforation process. When the light-emitting time reaches the preset value, the system automatically ends the light-emitting operation and completes the slow-start knife perforation stage.

[0069] 2. Cutting stage: After the slow-start perforation is completed, the system enters the cutting stage. First, the cutting peak power is set to ensure that the intensity of the laser cutting meets the cutting thickness requirements.

[0070] Next, the system starts to adjust the gas pressure, main oxygen pressure and preheating pressure. The gas pressure is gradually adjusted to the gas pressure required for cutting according to the gas change rate; the main oxygen pressure is gradually adjusted to the gas pressure required for cutting according to the main oxygen change rate, and the preheating pressure also reaches the cutting preheating pressure according to the preset change rate. The adjustment of these pressure parameters ensures the stability of the airflow during flame cutting and avoids the influence of pressure fluctuations on cutting quality.

[0071] At the same time, the Z-axis height is adjusted to the cutting height to ensure that the distance between the cutting head and the material surface remains stable to support the subsequent cutting process.

[0072] When all parameters are adjusted, the system starts the cutting mode. The cutting head moves along the cutting track at the preset cutting speed, and the system maintains the duty cycle and frequency of the light output mode to ensure a smooth cutting section.

[0073] After the cutting track is completed, the system monitors the light emission time. When the set light emission time is reached, the system automatically stops emitting light, indicating that the cutting of the current contour is completed.

[0074] 3. End of contour cutting and reset: After the contour cutting is completed, the system turns off the main oxygen pressure and the Z axis of the cutting head rises to the upper lifting height to prevent the cutting head from contacting the material surface and causing damage.

[0075] Finally, the system confirms that the cutting is complete. If the entire cutting is not completed, the cutting head will move to the starting point of the next contour and restart the piercing and cutting process.

[0076] 4. Module collaboration and process control: During the entire perforation and cutting process, the adaptive switching module, dual height tracking module and fault self-detection module work together. For example, the adaptive switching module dynamically adjusts the parameters of the laser and flame during the switching stage to ensure seamless connection from perforation to cutting.

[0077] The dual height tracking module adjusts the height of the cutting head in real time, allowing the laser and flame cutting to maintain the optimal cutting distance at different stages.

[0078] The fault self-check module monitors parameters such as air pressure, laser power and temperature at each stage of cutting. When abnormal parameters are detected, the system will automatically switch to backup mode or alarm to ensure the safety of equipment and materials.

[0079] Through the above-mentioned implementation mode, the composite cutting and perforation execution process of the present invention realizes accurate and efficient cutting operations, ensuring the cutting quality and the safety of the equipment.

[0080] Embodiment 5: In this embodiment, specific implementation methods of each module in different scenarios are described in detail, and are illustrated through various examples.

[0081] 1. The intelligent switching algorithm unit of the adaptive switching module adopts a dynamic analysis algorithm to intelligently switch the cutting mode according to the real-time feedback of cutting data (such as material thickness, thermal characteristics, and cutting path complexity). The algorithm includes the following key steps: Path identification and complexity analysis: The algorithm first receives and analyzes the shape and complexity of the cutting path. When the path is straight and the cutting material is thin (such as 5mm steel plate), the system selects the laser cutting mode to ensure efficient and accurate cutting. However, when the path contains multiple bending points or the material is thick (such as more than 15mm), the system automatically prioritizes flame cutting or compound cutting mode to cope with the challenge of heat diffusion during the cutting process.

[0082] Analysis of thermal properties of materials: The system uses the thermal diffusion data fed back by the sensor to determine the thermal properties of the material. For example, if cutting highly thermally sensitive materials such as aluminum or copper, the system will select lower power laser cutting to reduce the impact of thermal stress. For heat-resistant materials such as stainless steel, the system can increase the laser power or flame cutting time to ensure cutting speed and edge smoothness.

[0083] Dynamic thickness monitoring and mode adjustment: When the system detects a change in material thickness (such as an increase from 10mm to 20mm), the system uses a dynamic adjustment algorithm to prioritize flame cutting or compound cutting mode, using laser in the perforation stage and flame in the subsequent cutting stage. This intelligent switching process ensures a balance between cutting efficiency and quality, avoiding the tedious manual adjustment.

[0084] For example, when cutting a 15mm thick alloy steel plate, the system first completes perforation in laser cutting mode through path recognition and thickness monitoring, and then automatically switches to composite cutting mode to complete subsequent cutting, thereby increasing the cutting speed of the thick plate and ensuring the smoothness of the cut section.

[0085] 2. The specific implementation of the dual height tracking module in different cutting modes is as follows: High-precision control in laser cutting mode: During laser cutting, the laser sensor detects the distance between the cutting head and the material surface in real time, and the control system maintains the height with an accuracy of 0.1mm to ensure the laser focusing accuracy. For example, when the cutting head detects that the distance deviates slightly from the set value (such as the deviation exceeds 0.05mm), the system will immediately adjust the position of the cutting head to avoid focus drift.

[0086] Tolerance control in flame cutting mode: During flame cutting, the system gives priority to the feedback signal of the flame sensor, allowing a larger height deviation (within 1mm) to ensure the height stability of the cutting head. The lower accuracy of the flame sensor is sufficient to cope with the larger tolerance requirements of flame cutting, and the high durability design of the system effectively reduces the loss of the sensor, which is suitable for thick plate cutting.

[0087] Signal fusion and dynamic adjustment in compound cutting mode: In compound mode, the system collects data from laser and flame sensors at the same time, and ensures optimal control of the cutting head height through signal fusion algorithm. Taking the cutting of a 20mm thick stainless steel plate as an example, the system first uses the laser sensor to control the precise height in the perforation stage, and then dynamically adjusts the height according to the signal of the flame sensor in the flame cutting stage. The signal fusion algorithm is based on the principle of high priority of laser sensors and moderate assistance of flame sensors, balancing the role of the two in height adjustment, ensuring that the cutting head height is in the best position in different modes, and ultimately achieving high efficiency and stability of compound cutting.

[0088] 3. The fault self-check module is equipped with a laser power monitor, a gas pressure sensor and a cutting head temperature sensor to monitor the equipment status in real time. The specific implementation is as follows: Laser power monitoring: During the laser cutting stage, if the laser power monitor detects power abnormality (such as laser power is lower than 90% of the preset value), the system infers that the laser temperature is too high or the light source is faulty, automatically triggers an alarm signal and switches to flame cutting mode to prevent cutting interruption.

[0089] Gas pressure monitoring: During flame cutting, the gas pressure sensor is used to detect changes in gas pressure during cutting. When the pressure is insufficient or too high (such as less than 80% or more than 120% of the preset value), the system automatically pauses cutting and switches to laser mode, or triggers the backup gas switch to ensure production continuity and safety.

[0090] Cutting head temperature monitoring and emergency mode: The cutting head temperature sensor detects the real-time temperature of the cutting head. When the temperature exceeds the safety threshold (such as 110% of the set temperature), the system automatically activates the emergency cutting mode, reduces the cutting speed, allows the operator to manually adjust, or switch to semi-automatic mode. This emergency function is particularly important when the equipment is used intensively or the ambient temperature is high, ensuring the safety and stability of the equipment.

[0091] 4. The intelligent cutting path optimization module uses a path planning algorithm to perform intelligent management of the heat affected zone. The specific implementation methods are as follows: Heat-affected zone bypass and cooling control: When cutting thick plates (such as 30mm steel plates), the module detects the data from the temperature sensor to identify the heat-affected zone and avoid thermal stress concentration. When the temperature in a certain area is too high (such as over 300°C), the module automatically replans the path to bypass the high-temperature area and wait for it to cool before cutting, thereby reducing thermal stress accumulation and reducing the risk of material deformation.

[0092] Path optimization based on material properties: The module can automatically adjust the cutting head movement speed along the path according to the thermal sensitivity and diffusion coefficient of different materials. For example, when cutting aluminum alloy plates, the path optimization algorithm will slow down the cutting edge stage to ensure edge smoothness and avoid overheating. On low heat-sensitive materials (such as steel), a higher cutting speed is maintained to improve efficiency. This dynamic path adjustment based on material properties significantly improves the controllability of cutting quality.

[0093] 5. The data fusion and cloud linkage module realizes intelligent recommendation and parameter optimization through the cloud database. The specific implementation methods are as follows: Automatic optimization of cutting parameters: The module stores and updates the parameters and effect data of each cutting in the cloud. For example, when a user cuts a 15mm thick stainless steel plate multiple times and tends to use the compound cutting mode, the cloud linkage module will automatically recommend optimized laser power, flame temperature, cutting speed and other parameters, reducing the operator's manual debugging time.

[0094] Intelligent recommendation and data sharing between devices: The module recommends the best cutting mode and path for different materials and thicknesses to users based on the historical data of different users. For example, after the user of device A successfully cuts a 25mm steel plate, the cloud automatically records the configuration parameters. When the user of device B operates under similar conditions, the system automatically recommends the best parameter configuration of device A to improve production consistency and efficiency. The data sharing function of the cloud linkage module effectively accumulates application experience of different cutting parameters and provides operators with guiding suggestions for cutting configuration.

[0095] Embodiment 6: This embodiment further describes in detail the application of the three cutting methods of laser, flame and laser-flame composite in different scenarios. The system not only supports the laser-flame composite cutting mode, but can also flexibly switch to single laser or single flame cutting mode when needed to adapt to different material properties, plate thickness and cutting quality requirements.

[0096] In actual operation, the adaptive switching module dynamically selects single laser cutting, single flame cutting or laser-flame composite cutting mode according to the real-time feedback of cutting data through the intelligent switching algorithm unit to achieve higher cutting efficiency and quality.

[0097] 1. Single laser cutting mode: When cutting thin and uniform metal sheets, the system gives priority to single laser cutting mode to achieve high precision and fast perforation. The adaptive switching module judges whether it is suitable for laser cutting through the material thickness data fed back by the sensor. When the thickness is small (for example, less than 10mm) and the path complexity is low, the system automatically switches to laser cutting mode, and uses a high-precision laser sensor to keep the distance between the cutting head and the material surface within 0.1mm to ensure accurate laser focus and excellent cutting quality. For example, when cutting a 5mm thick steel plate, the system selects single laser mode to provide higher cutting speed and accuracy, while reducing the heat-affected area of ​​the material and improving the smoothness of the cutting edge.

[0098] 2. Single flame cutting mode: For thicker steel or stainless steel and other materials with higher heat resistance, the system can automatically select the single flame cutting mode to obtain a smoother cutting surface. In the single flame cutting mode, the adaptive switching module judges the material thickness and the complexity of the cutting path based on the feedback data, and switches the cutting mode to flame cutting. At this time, the system uses the flame sensor to keep the height of the cutting head within a fluctuation range of 2mm, meeting the height tolerance requirements of flame cutting and ensuring the stability and quality of flame cutting. For example, when cutting a 20mm thick stainless steel plate, the system automatically switches to the single flame cutting mode, giving priority to the flame sensor feedback to adjust the height of the cutting head to complete the cutting smoothly and stably.

[0099] 3. Laser-flame composite cutting mode: For workpieces with large thickness and high cutting edge requirements, the system automatically switches between single laser and single flame modes to laser-flame composite cutting mode to fully utilize the perforation speed of laser cutting and the smooth section effect of flame cutting. In composite mode, the system relies on the high-precision laser sensor and low-precision flame sensor of the dual height tracking module to maintain precise control of the laser sensor during the laser perforation stage to ensure the laser focus. The flame cutting stage of the cutting process relies on the flame sensor, allowing a larger height tolerance range for the cutting head to meet the requirements of flame cutting for thermal expansion. For example, when cutting a 25mm thick alloy steel plate, the system first completes rapid perforation in laser mode, and then switches to flame mode for precise cutting along the edge. Through the signal coordination of the laser and flame sensors, a high degree of dynamic adjustment is achieved to ensure the overall accuracy and smoothness of the composite cutting.

[0100] 4. Dynamic switching mechanism: During the entire cutting process, the adaptive switching module automatically switches between single laser, single flame and compound cutting modes according to material characteristics, thickness changes and the complexity of the cutting path. For example, when the system detects thin steel plates, single laser cutting is preferred; while in the cutting of thick steel plates or heat-sensitive materials, the system will switch to flame or compound mode through path analysis and thermal diffusion analysis to ensure the best balance between cutting quality and efficiency.

[0101] 5. Fault self-checking and emergency switching: During the cutting process, if the laser or flame sensor detects abnormal power or pressure, the system will automatically switch to the available single cutting mode to ensure the continuity of production. For example, when the laser power is abnormal, the system switches to the single flame cutting mode to continue the operation; conversely, when the flame sensor detects insufficient gas pressure, the system switches to the single laser mode to complete the remaining cutting task. Through the fault warning function of the fault self-checking module, the system can automatically trigger the switch when an abnormality is detected to ensure the stability of the cutting process.

[0102] 6. Intelligent cutting path optimization and mode adaptation: The intelligent cutting path optimization module optimizes the cutting path in real time, and selects the appropriate cutting mode on different paths by dynamically analyzing the heat-sensitive area and material properties. For example, when there are uneven thickness areas on the same steel plate, the path optimization module will automatically switch to single laser mode in the thin area and switch to flame or composite mode in the thick area to balance the heat effect, reduce material deformation, and ensure the neatness and smoothness of the cutting edge.

[0103] This example demonstrates how the system dynamically selects and switches between single laser, single flame, and laser-flame composite cutting modes according to different cutting scenarios, which not only improves cutting efficiency and quality, but also improves the flexibility and adaptability of the system, meeting the cutting requirements of different materials and complex cutting needs. This multi-mode cutting selection mechanism enables the system to flexibly respond to a variety of cutting tasks, further improving the scope of application and operating efficiency of the equipment in actual production.

[0104] In summary, this embodiment further demonstrates the specific implementation methods of each module, especially the collaborative work of each module under complex cutting requirements, ensuring that the system can efficiently and intelligently complete the cutting work under different conditions. Through detailed algorithm description and signal fusion mechanism, each module not only improves the cutting efficiency and quality, but also greatly enhances the intelligence and reliability of the equipment.
