Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a method, apparatus, electronic device, and storage medium for preventing chuck burn-out. Background Technology

[0002] During pipe processing, especially for structural steel (e.g., L-shaped, C-shaped, or H-shaped steel), when the beveling path of the pipe is introduced from outside the plate, the laser cutter can directly burn the chuck or jaws, causing chuck damage and affecting the subsequent pipe cutting accuracy. To avoid chuck damage, the programmable logic controller (PLC) function in software currently determines the relative position between the chuck and the laser cutter based on the normal vector of the cutting surface in the air, and then sends commands to the servo motor to control the chuck to move to the anti-burn position.

[0003] However, in the above method, the chuck moves to the anti-burn position and then stops moving, so the anti-burn position is fixed. During the pipe processing, technicians need to manually adjust the anti-burn position of the chuck. If the technician adjusts the anti-burn position of the chuck too far, the pipe cutting effect will be poor due to the long return time of the chuck. If the technician manually adjusts the anti-burn position of the chuck too close, the anti-burn effect of the chuck will be poor, which may lead to burning of the chuck or jaws, resulting in chuck damage and significant economic losses. Summary of the Invention

[0004] This invention provides a method, device, electronic equipment, and storage medium for preventing chuck burn-out. It adaptively determines the target burn-out position based on the beveling trajectory, eliminating the need for a fixed target burn-out position and allowing the chuck to automatically move to the accurate target position. This eliminates the need for manual adjustment by technicians, improving the speed and accuracy of moving the chuck to the target burn-out position, thereby enhancing the burn-out prevention effect. It solves the problem of technicians adjusting the chuck burn-out position too far, resulting in a long chuck return time and poor pipe cutting results. It also addresses the issue of technicians manually adjusting the chuck burn-out position too close, leading to poor burn-out prevention and chuck damage, causing significant economic losses. This invention reduces economic losses due to chuck damage during pipe processing.

[0008] Based on the target anti-burn position and the target swing angle, determine the movement mode of the laser cutter and the chuck;

[0009] The laser cutter is moved to the target swing angle according to the described movement method, and the chuck is moved to the target anti-burn position.

[0010] According to a second aspect of the present invention, a chuck anti-burn device is provided, the device comprising:

[0011] The trajectory acquisition module is used to acquire the beveling trajectory of the pipe to be processed, and to determine the target swing angle that the laser cutter will switch to based on the beveling trajectory.

[0012] The position determination module is used to obtain the interval distance between the chuck and the irradiation position of the laser cutter, the anti-burn compensation value, the pipe diameter and the swing arm length of the laser cutter, and to determine the target anti-burn position of the chuck based on the target swing angle, the interval distance, the anti-burn compensation value, the pipe diameter and the swing arm length;

[0013] The movement mode determination module is used to determine the movement mode of the laser cutter and the chuck based on the target anti-burn position and the target swing angle;

[0014] The position movement module is used to move the laser cutter to the target swing angle according to the movement method, and to move the chuck to the target anti-burn position.

[0015] According to a third aspect of the present invention, an electronic device is provided, comprising a processor and a memory.

[0016] The memory is used to store code and related data;

[0017] The processor is used to execute code in the memory to implement the chuck anti-burning method as described in any of the embodiments of the present invention.

[0018] According to a fourth aspect of the present invention, a storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the chuck anti-burning method as described in any of the embodiments of the present invention.

[0019] In this embodiment of the invention, the beveling trajectory of the pipe to be processed is obtained, and the target swing angle of the laser cutter to be switched is determined based on the beveling trajectory; the interval distance between the chuck and the irradiation position of the laser cutter, the anti-burn compensation value, the pipe diameter, and the swing arm length of the laser cutter are obtained, and the target anti-burn position of the chuck is determined based on the target swing angle, interval distance, anti-burn compensation value, pipe diameter, and swing arm length; the movement mode of the laser cutter and chuck is determined based on the target anti-burn position and the target swing angle, and the laser cutter is moved to the target swing angle and the chuck is moved to the target anti-burn position according to the movement mode. That is, during the pipe processing according to the beveling trajectory, the laser cutter is switched to the target swing angle based on the beveling trajectory. The purpose of adaptive determination of the target anti-burn position in the cutting trajectory is to eliminate the fixed target anti-burn position of the chuck and enable automatic movement of the chuck to the accurate target anti-burn position.

This reduces the economic losses caused by chuck damage during pipe processing. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] The terms “comprising” and “having”, and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0032] The technical solution of the present invention will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0033] Figure 1 This is a flowchart illustrating a chuck anti-burning method provided in an embodiment of the present invention. This method can be executed by a chuck anti-burning device, which can be implemented using software and / or hardware. In a specific embodiment, this device can be integrated into an electronic device, such as a computer or server. The following embodiments will illustrate this using the integration of the device into an electronic device as an example. Figure 1 The method may specifically include the following steps:

[0034] Step 101: Obtain the beveling trajectory of the pipe to be processed, and determine the target swing angle that the laser cutter will switch to based on the beveling trajectory.

[0035] The pipe can be shaped steel, such as L-shaped steel, C-shaped steel, or H-shaped steel; the beveling trajectory can be understood as the cutting trajectory of the laser cutter processing the pipe; the laser cutter can include a swing arm, a cutting head, and a rotation center, such as... Figure 2 As shown, the straight line L, which is parallel to the chuck and perpendicular to the cross-section of the tube, with the rotation center O as the starting point, is taken as the reference line. The swing angle can be understood as the angle formed between the swing arm of the laser cutter and the reference line.

[0036] In one alternative implementation, the beveling trajectory of the pipe to be processed can be directly obtained from the beveling trajectory determination software; then, based on the beveling trajectory, multiple candidate swing angles that the laser cutter is about to switch to are determined, and the target swing angle that the laser cutter is about to switch to is determined from the multiple candidate swing angles.

[0037] Specifically, three-dimensional editing software can be used to determine multiple normal vectors of the beveling trajectory in space, and then multiple angles formed by the multiple normal vectors and the reference line can be determined. These multiple angles are then identified as multiple candidate swing angles that the laser cutter is about to switch to.

[0038] For example, the beveling trajectory of the pipe to be processed can be directly obtained from the beveling trajectory determination software; then, multiple normal vectors (V1, V2, V3) of the beveling trajectory in space can be determined using 3D editing software; then, multiple angles (A1, A2, A3) formed by the multiple normal vectors and the reference line can be determined; these multiple angles can be determined as multiple candidate swing angles (A1, A2, A3) that the laser cutter is about to switch to; and finally, the target swing angle that the laser cutter is about to switch to can be determined from the multiple candidate swing angles.

[0039] Step 102: Obtain the interval distance between the chuck and the irradiation position of the laser cutter, the anti-burn compensation value, the pipe diameter, and the swing arm length of the laser cutter. Based on the target swing angle, interval distance, anti-burn compensation value, pipe diameter, and swing arm length, determine the target anti-burn position of the chuck.

[0040] Among them, the irradiation position can be understood as the point on the machine tool where the red light of the laser cutter is irradiated; the interval distance can be understood as the straight-line distance between the pipe and the irradiation position of the laser cutter; the anti-burn compensation value can be understood as the height of the roller below the chuck; and the anti-burn position can be understood as the position of the chuck that is not irradiated by the red light of the laser cutter.

[0041] In one optional implementation, a first vertical distance between the rotation center of the laser cutter and the upper surface of the pipe can be determined based on the target swing angle and the swing arm length. A second vertical distance between the rotation center of the laser cutter and the lower edge of the anti-burn compensation area can be determined based on the first vertical distance, the pipe diameter, and the anti-burn compensation value. A safe distance between the chuck and the irradiation position of the laser cutter can be determined based on the second vertical distance and the target swing angle. Based on the current position of the chuck, the interval distance, and the safe distance, the target anti-burn position of the chuck can be determined in real time according to the target swing angle, the interval distance, the anti-burn compensation value, the pipe diameter, and the swing arm length. This achieves the purpose of adaptively determining the target anti-burn position based on the target swing angle, improving the anti-burn effect of the chuck. It avoids the problem that the pipe cutting effect is affected and the pipe processing efficiency is affected by the technician manually moving the chuck too far to the target anti-burn position. It also avoids the problem that the chuck or jaws are burned due to the technician manually adjusting the chuck position too close, resulting in chuck damage. This extends the service life of the chuck and reduces the economic losses incurred during pipe processing. The first vertical distance can be understood as the straight-line distance between the rotation center of the laser cutter and the upper surface of the pipe; the second vertical distance can be understood as the straight-line distance between the rotation center of the laser cutter and the lower edge of the roller below the chuck; the safety distance can be understood as the straight-line distance between the chuck and the irradiation position of the laser cutter.

[0042] For example, such as Figure 2 As shown, the target swing angle is The interval distance is M, the pipe diameter is Q, and the target swing angle of the laser cutter is... At that time, the swing arm of the laser cutter is in a straight line OS, and the red light of the laser cutter is... Figure 2 The dashed line ST represents the length of the laser cutter's swing arm, K, and the rotation center O. The anti-burn compensation value P can be determined based on the target swing angle. Given the arm length K, determine the first vertical distance L1 between the rotation center O of the laser cutter and the upper surface of the pipe. Based on the first vertical distance L1, the pipe diameter Q, and the anti-burn compensation value P, determine the second vertical distance L2 between the rotation center O of the laser cutter and the lower edge of the anti-burn compensation area. Based on the second vertical distance L2 and the target swing angle... Determine the safe distance L3 between the chuck and the irradiation position of the laser cutter. Based on the current position of the chuck, the interval distance M, and the safe distance L3, determine the target anti-burn position of the chuck.

[0043] Step 103: Determine the movement mode of the laser cutter and chuck based on the target anti-burn position and target swing angle.

[0044] The movement methods of the laser cutter and the chuck can include moving them simultaneously, moving the laser cutter first and then moving the chuck, and moving the chuck first and then moving the laser cutter.

[0045] In one optional implementation, preset information can be queried based on the target anti-burn position and target swing angle to determine the coordinate region to which the target anti-burn position and target swing angle belong. The movement method of the laser cutter and chuck is determined based on the coordinate region. This allows for faster and more accurate determination of the coordinate region to which the target anti-burn position and target swing angle belong. Then, based on the coordinate region, the movement method of the laser cutter and chuck is determined, and the laser cutter is quickly moved to the target swing angle, and the chuck is quickly moved to the target anti-burn position. This shortens the chuck return time and increases the speed of moving the chuck to the target anti-burn position, thereby improving the pipe processing speed and efficiency. This avoids the problems caused by technicians manually moving the chuck too far to the target anti-burn position, which affects the pipe cutting effect and the long chuck return time, thus reducing pipe processing efficiency. It also avoids the problem of technicians manually adjusting the chuck position too close, which can burn the chuck or jaws and cause chuck damage. This extends the chuck's service life and reduces economic losses during pipe processing. The preset information may include the coordinate regions corresponding to each target anti-burn position and target swing angle.

[0046] For example, in the preset information, the target anti-burn position is Y and the target swing angle is... The corresponding coordinate region is S. Assuming the movement mode corresponding to coordinate region S is simultaneous movement, it can be determined based on the target's anti-burn position Y and the target's swing angle. Query the preset information, determine the coordinate area S to which the target anti-burn position and target swing angle belong, and determine that the laser cutter and chuck move simultaneously.

[0047] Step 104: Move the laser cutter to the target swing angle according to the movement method, and move the chuck to the target anti-burn position.

[0048] In one optional implementation, when the movement is simultaneous, the laser cutter is moved from the current swing angle to the target swing angle, and the chuck is moved from the current position to the target anti-burn position; when the movement is to move the laser cutter first and then the chuck, the laser cutter is moved from the current swing angle to the target swing angle, and then the chuck is moved from the current position to the target anti-burn position; when the movement is to move the chuck first and then the laser cutter, the chuck is moved from the current position to the target anti-burn position, and then the laser cutter is moved from the current swing angle to the target swing angle. This can prevent the laser cutter and the chuck from colliding during the movement of the laser cutter and the chuck, thus avoiding damage to the chuck and affecting the cutting accuracy of the subsequent pipe.

[0049] For example, such as Figure 3As shown, the red light from the laser cutter can burn the chuck, indicating that the chuck needs to be moved to an anti-burn position. When the movement is determined to be simultaneous, the laser cutter is moved from its current swing angle... Move to the target swing angle And move the chuck from its current position X to the target anti-burn position Y.

[0050] In this embodiment of the invention, the beveling trajectory of the pipe to be processed at multiple chucks can be obtained. Based on these trajectories, the target swing angle of each laser cutter is determined. The interval distance between each chuck and the irradiation position of the laser cutter, the anti-burn compensation value, the pipe diameter of each pipe, and the swing arm length of each laser cutter are obtained. Based on the target swing angle, interval distance, anti-burn compensation value, pipe diameter, and swing arm length, the target anti-burn position of each chuck is determined. Based on the target anti-burn position and target swing angle, the movement mode of each laser cutter and each chuck is determined. The laser cutter is then moved according to the movement mode. The device moves to the corresponding target swing angle, and moves each chuck to the corresponding target anti-burn position. For multi-chuck models, since it is only necessary to obtain the beveling trajectory of the pipe to be processed at each chuck, the target anti-burn position of each chuck is determined in real time based on the beveling trajectory of the pipe to be processed at each chuck, and each chuck is moved to the target anti-burn position, the chuck anti-burn purpose of multi-chuck models is achieved. There is no limit to the number of chucks in the model, and it is applicable to multi-chuck models, which increases the model versatility of chuck anti-burn and solves the problem of poor versatility of existing chuck anti-burn methods due to the fixed anti-burn position.

[0051] In this embodiment of the invention, during pipe processing based on the beveling trajectory, the target anti-burn position is adaptively determined according to the beveling trajectory. The target anti-burn position of the chuck is no longer fixed, and the chuck can automatically move to the accurate target anti-burn position, eliminating the need for technicians to manually adjust the chuck to the target anti-burn position. This improves the speed and accuracy of moving the chuck to the target anti-burn position, thereby enhancing the anti-burn effect of the chuck. It also solves the problem of poor pipe cutting results caused by technicians adjusting the chuck anti-burn position too far, resulting in a long chuck return time, and also addresses the issue of technicians manually adjusting the chuck anti-burn position too close, which reduces the anti-burn effect. This method addresses the issue of chuck damage leading to significant economic losses during pipe processing. Furthermore, for multi-chuck models, it only requires acquiring the beveling trajectory of the pipe to be processed at each chuck. Based on this trajectory, the target anti-burn position for each chuck is determined in real-time, and each chuck is moved to the target anti-burn position. This achieves chuck anti-burn protection for multi-chuck models without limitation on the number of chucks, increasing the versatility of chuck anti-burn protection and resolving the problem of poor versatility caused by fixed anti-burn positions in existing chuck anti-burn methods.

[0052] The following further explains the chuck anti-burning method provided in the embodiments of the present invention, such as... Figure 4 As shown, Figure 4 This is another schematic flowchart of the chuck anti-burning method provided in this embodiment of the invention, which may specifically include the following steps:

[0053] Step 201: Obtain the beveling trajectory of the pipe to be processed.

[0054] Step 202: Determine multiple candidate swing angles that the laser cutter will switch to based on the beveling trajectory.

[0055] Step 203: Determine the largest swing angle among multiple candidate swing angles as the target swing angle that the laser cutter is about to switch to.

[0056] For example, the laser cutter is about to switch to multiple candidate swing angles (A1, A2, A3), where A1>A2>A3. The largest swing angle A1 among the multiple candidate swing angles is determined as the target swing angle that the laser cutter is about to switch to.

[0057] In this embodiment of the invention, multiple candidate swing angles that the laser cutter will switch to can be determined based on the beveling trajectory. The largest candidate swing angle is determined as the target swing angle. Then, based on the target swing angle, interval distance, anti-burn compensation value, pipe diameter, and swing arm length, the target anti-burn position with the farthest distance between the chuck and the laser cutter can be accurately determined. For large steel sections, the chuck can be moved to the farthest target anti-burn position in one go, ensuring that the chuck will not be burned during pipe processing, reducing the impact of chuck damage on the pipe processing effect, and improving the pipe processing effect of large steel sections. It eliminates the need to frequently move the chuck to the anti-burn position corresponding to each candidate swing angle during the process of the laser cutter switching from the current swing angle to the target swing angle. This solves the problem of severely shortening the chuck's service life due to frequent movement of the chuck loaded with large steel sections, extends the chuck's service life, and improves the chuck's anti-burn effect.

[0058] Step 204: Obtain the interval distance between the chuck and the irradiation position of the laser cutter, the anti-burn compensation value, the pipe diameter, and the swing arm length of the laser cutter.

[0059] For example, users can open the cassette control software on the client and enter, such as... Figure 5 In the software interface shown, select Tools - Debugging Tools - Chuck Debugging - Chuck Anti-burn / Interference Calibration in sequence, and then enter as follows: Figure 6 The chuck anti-burn / interference calibration interface shown allows the user to input the interval distance M and the anti-burn compensation value P. The user then enters the interval distance M and the anti-burn compensation value P and clicks [the relevant button / click]. Figure 6After saving the control, obtain the interval distance and anti-burn compensation value, and directly obtain the pipe diameter Q and the swing arm length K of the laser cutter from the database.

[0060] Step 205: Determine the first vertical distance between the rotation center of the laser cutter and the upper surface of the tube based on the target swing angle and the swing arm length.

[0061] In one alternative implementation, the product of the cosine function value of the target swing angle and the swing arm length is used as the first vertical distance between the rotation center of the laser cutter and the upper surface of the tube.

[0062] For example, the target swing angle is The length of the laser cutter's swing arm is K, and the cosine function value of the target swing angle ( The product of the length of the swing arm and the length of the swing arm. L1 is the first vertical distance between the rotation center of the laser cutter and the upper surface of the tube.

[0063] Step 206: Determine the second vertical distance between the rotation center of the laser cutter and the lower edge of the anti-burn compensation area based on the first vertical distance, the pipe diameter, and the anti-burn compensation value.

[0064] In one alternative implementation, the sum of the anti-burn compensation value and the pipe diameter is used as the intermediate distance; the sum of the intermediate distance and the first vertical distance is used as the second vertical distance.

[0065] For example, the target swing angle is The pipe diameter is Q, the laser cutter arm length is K, and the anti-burn compensation value is P; the sum of the anti-burn compensation value and the pipe diameter ( ) as the intermediate distance, and the sum of the intermediate distance and the first perpendicular distance ( ) as the second vertical distance L2.

[0066] Step 207: Determine the safe distance between the chuck and the irradiation position of the laser cutter based on the second vertical distance and the target swing angle.

[0067] In one alternative implementation, the product of the tangent function value of the target swing angle and the second vertical distance is used as the safe distance between the chuck and the irradiation position of the laser cutter.

[0068] For example, the product of the tangent function value of the target swing angle and the second perpendicular distance ( L3 is the safety distance between the chuck and the irradiation position of the laser cutter.

[0069] Step 208: Determine the target anti-burn position of the chuck based on the current position, interval distance, and safety distance of the chuck.

[0070] In one optional implementation, when the interval distance is greater than the safety distance, it indicates that the chuck at the current position will not be burned by the laser cutter, and therefore there is no need to move the chuck for burn prevention; that is, there is no need to determine the target burn prevention position of the chuck. When the interval distance is less than the safety distance, it indicates that the chuck at the current position will be burned by the laser cutter, and therefore it is necessary to move the chuck for burn prevention; that is, it is necessary to determine the target burn prevention position of the chuck. The difference between the interval distance and the safety distance can be used as the moving distance of the chuck. The target burn prevention position of the chuck is determined based on the moving distance and the current position of the chuck. The current position includes the current horizontal coordinate and the current vertical coordinate.

[0071] Specifically, the sum of the current horizontal coordinate and the moving distance is used as the target horizontal coordinate of the chuck, and the current vertical coordinate is determined as the target vertical coordinate of the chuck. The coordinate positions corresponding to the target horizontal and vertical coordinates are determined as the target anti-burn position of the chuck. This improves the accuracy of determining the target anti-burn position, thereby moving the chuck to the accurate target anti-burn position, improving the anti-burn effect of the chuck, and avoiding the problem that the pipe cutting effect is affected and the pipe processing efficiency is affected by the technician manually moving the chuck too far to the target anti-burn position. It also avoids the problem that the chuck or jaws are burned due to the technician manually adjusting the chuck position too close, resulting in chuck damage. This extends the service life of the chuck and reduces the economic losses incurred in the pipe processing process.

[0072] For example, such as Figure 2 As shown, the interval distance is M, the safety distance is L3, the current horizontal coordinate is x, and the current vertical coordinate is y. If the value of M-L3 is positive, it means that the chuck can achieve anti-burning without retraction, and there is no need to determine the target anti-burning position of the chuck. If the value of M-L3 is negative, it means that the chuck needs to retract for anti-burning. In this case, the difference between the interval distance and the safety distance (L3-M) is taken as the moving distance D of the chuck. The sum of the current horizontal coordinate and the moving distance is taken as the target horizontal coordinate (x+D) of the chuck. The current vertical coordinate is determined as the target vertical coordinate (y) of the chuck. The coordinates corresponding to the target horizontal coordinate and the target vertical coordinate are determined as the target anti-burning position of the chuck (x+D, y).

[0073] Step 209: Query preset information based on the target fire prevention position and target swing angle to determine the coordinate area to which the target fire prevention position and target swing angle belong. The preset information includes the coordinate area corresponding to each target fire prevention position and target swing angle.

[0074] Step 210: Determine the movement mode of the laser cutter and chuck based on the coordinate region.

[0075] The coordinate region can include a first coordinate region, a second coordinate region, and a third coordinate region. The first coordinate region can be understood as the coordinate region consisting of multiple chuck positions determined when the chuck and laser cutter move simultaneously without causing the chuck to be burned; the second coordinate region can be understood as the coordinate region consisting of multiple chuck positions determined when the laser cutter moves first and then the chuck without causing the chuck to be burned; the third coordinate region can be understood as the coordinate region consisting of multiple chuck positions determined when the chuck moves first and then the laser cutter without causing the chuck to be burned.

[0076] In one optional implementation, when the coordinate region belongs to the first coordinate region, the laser cutter and chuck are moved simultaneously. This allows the chuck and laser cutter to move in parallel, achieving a leapfrog motion linkage between the chuck and laser cutter, reducing the movement time of the chuck and laser cutter, and thus reducing the time required to move the chuck to the target anti-burn position, improving the anti-burn speed of the chuck. When the coordinate region belongs to the second coordinate region, the laser cutter is moved first, followed by the chuck. When the coordinate region belongs to the third coordinate region, the chuck is moved first, followed by the laser cutter. This allows the chuck and laser cutter to move sequentially when the coordinate region belongs to the second or third coordinate region. During the movement of the laser cutter and chuck, collisions between them are avoided, preventing chuck damage that could affect the cutting accuracy of subsequent pipes. This better ensures the cutting accuracy of the pipes and reduces economic losses during pipe processing.

[0077] For example, in the preset information, the target anti-burn position is Y and the target swing angle is... The corresponding coordinate region is S; it can be determined based on the target's anti-burn position Y and the target's swing angle. Query the preset information, determine the coordinate area of ​​the target anti-burn position and the target swing angle as the first coordinate area, and determine the movement mode of the laser cutter and the chuck as simultaneous movement.

[0078] Step 211: Move the laser cutter to the target swing angle according to the movement method, and move the chuck to the target anti-burn position.

[0079] In this embodiment of the invention, during pipe processing based on the beveling trajectory, the target anti-burn position is adaptively determined according to the beveling trajectory. The target anti-burn position of the chuck is no longer fixed, and the chuck can be automatically moved to the accurate target anti-burn position without the need for technicians to manually adjust the chuck to the target anti-burn position. This improves the speed and accuracy of moving the chuck to the target anti-burn position, thereby improving the anti-burn effect of the chuck. It solves the problem that when technicians adjust the chuck anti-burn position too far, the chuck returns to its original position for a long time, resulting in poor pipe cutting effect. It also solves the problem that when technicians manually adjust the chuck anti-burn position too close, the anti-burn effect of the chuck is poor, leading to chuck damage and significant economic losses. This reduces the economic losses caused by chuck damage during pipe processing.

[0080] The following further explains the chuck anti-burning method provided in the embodiments of the present invention, such as... Figure 7 As shown, Figure 7 This is another flowchart illustrating the chuck anti-burning method provided in this embodiment of the invention, which may specifically include the following steps:

[0081] Step 301: Obtain the beveling trajectory of the pipe to be processed.

[0082] Step 302: Determine multiple candidate swing angles that the laser cutter will switch to based on the beveling trajectory.

[0083] Step 303: The swing angle closest to the current swing angle of the laser cutter among multiple candidate swing angles is determined as the target swing angle that the laser cutter is about to switch to.

[0084] For example, the current swing angle is The laser cutter is about to switch to multiple candidate swing angles (A1, A2, A3), among which, >A1>A2>A3, the swing angle A1 that is closest to the current swing angle of the laser cutter among multiple candidate swing angles is determined as the target swing angle that the laser cutter is about to switch to.

[0085] In this embodiment of the invention, multiple candidate swing angles that the laser cutter is about to switch to are determined based on the beveling trajectory. The swing angle closest to the current swing angle of the laser cutter among the multiple candidate swing angles is determined as the target swing angle that the laser cutter is about to switch to. Then, based on the target swing angle, interval distance, anti-burn compensation value, pipe diameter, and swing arm length, the target anti-burn position closest to the laser cutter is accurately determined. In this way, when the pipe to be processed is a small or medium-sized steel section, the target anti-burn position can be determined in real time with each change of the laser cutter's swing angle, and the chuck can be moved to the anti-burn position corresponding to each candidate swing angle. That is, the chuck can be moved to the target anti-burn position closest to the current position of the chuck in real time for anti-burning, shortening the chuck return time. This avoids the problems of poor pipe processing effect and long chuck return time affecting pipe processing efficiency caused by technicians manually moving the chuck too far to the target anti-burn position. It reduces the impact of the target anti-burn position being too far on the pipe cutting effect, better ensures the cutting accuracy of the pipe, and improves the pipe processing effect of small and medium-sized steel sections.

[0086] Step 304: Obtain the interval distance between the chuck and the irradiation position of the laser cutter, the anti-burn compensation value, the pipe diameter, and the swing arm length of the laser cutter.

[0087] Step 305: Determine the first vertical distance between the rotation center of the laser cutter and the upper surface of the tube based on the target swing angle and the swing arm length.

[0088] Step 306: Determine the second vertical distance between the rotation center of the laser cutter and the lower edge of the anti-burn compensation area based on the first vertical distance, the pipe diameter, and the anti-burn compensation value.

[0089] Step 307: Determine the safe distance between the chuck and the irradiation position of the laser cutter based on the second vertical distance and the target swing angle.

[0090] Step 308: Determine the target anti-burn position of the chuck based on the chuck's current position, interval distance, and safety distance.

[0091] Step 309: Query preset information based on the target fire prevention position and target swing angle to determine the coordinate area to which the target fire prevention position and target swing angle belong. The preset information includes the coordinate area corresponding to each target fire prevention position and target swing angle.

[0092] Step 310: Determine the movement mode of the laser cutter and chuck based on the coordinate region.

[0093] Step 311: Move the laser cutter to the target swing angle according to the movement method, and move the chuck to the target anti-burn position.

[0094] In this embodiment of the invention, during pipe processing based on the beveling trajectory, the target anti-burn position is adaptively determined according to the beveling trajectory. The target anti-burn position of the chuck is no longer fixed, and the chuck can be automatically moved to the accurate target anti-burn position without the need for technicians to manually adjust the chuck to the target anti-burn position. This improves the speed and accuracy of moving the chuck to the target anti-burn position, thereby improving the anti-burn effect of the chuck. It solves the problem that when technicians adjust the chuck anti-burn position too far, the chuck returns to its original position for a long time, resulting in poor pipe cutting effect. It also solves the problem that when technicians manually adjust the chuck anti-burn position too close, the anti-burn effect of the chuck is poor, leading to chuck damage and significant economic losses. This reduces the economic losses caused by chuck damage during pipe processing.
