Description

Technical Field

[0001] This invention relates to the field of laser cutting machines, and more particularly to a method, system, and laser cutting machine for chip removal. Background Technology

[0002] A laser cutting machine is a device that uses a laser beam to cut, engrave, and mark materials. It utilizes a high-energy-density laser beam to heat the material to above its sublimation point or melting point, thereby achieving cutting.

[0003] Laser cutting machines contain a processing chamber for laser cutting, where the material cutting process typically takes place. The laser cutting process has strict requirements regarding the environment; it usually needs to be carried out in a dust-free environment to achieve higher cutting precision. However, laser cutting may generate debris and dust during the process, which can negatively impact cutting precision and reduce material processing quality. Therefore, it is necessary to manage the debris generated during the cutting process. Summary of the Invention

[0004] In order to remove the debris generated during the laser cutting process and improve the cutting accuracy of materials, this invention provides a laser cutting machine chip removal method, system and laser cutting machine.

[0005] In a first aspect, the present invention provides a chip removal method for a laser cutting machine, which adopts the following technical solution:

[0006] A method for removing chips from a laser cutting machine includes:

[0007] At a preset processing location, acquire physical characteristic image information of the material;

[0008] Product processing information is determined by matching vital sign image information with a pre-set product database.

[0009] Determine the product's cutting path information based on the product processing information;

[0010] The direction of the flying debris generated at the laser focusing point is determined based on the cutting path information;

[0011] The suction direction of the preset suction pipe, the blowing direction of the preset air blowing device, and the air wall direction of the air wall opening are determined according to the direction of the debris splash.

[0012] The suction pipe is controlled to suck up the flying debris according to the suction direction, and the blowing device is controlled to blow the debris on the material surface into the suction pipe according to the blowing direction. Simultaneously, the blowing device is controlled to blow air in the direction of the air wall on both sides of the laser focusing point to form an air wall to limit and guide the flying debris into the suction pipe.

[0013] In existing technologies, debris generated by the equipment is typically directly sucked up through a suction pipe. However, because the debris flies around when it is generated, the final dust removal effect of the suction pipe is not ideal. In this solution, the debris is processed simultaneously by the suction pipe and the air blowing device. The air blowing device's air wall can blow air to form an air wall to prevent the flying debris from flying around and guide the debris. Then, the air blowing port can blow the flying debris towards the suction pipe, thereby improving the dust removal and chip removal capacity of the suction pipe, making the laser cutting machine cleaner, and preventing the debris from affecting the laser cutting machine's cutting effect on materials, thus improving the cutting quality of the product.

[0014] Optional, also includes:

[0015] At preset shooting intervals, capture flight image information of flying debris at the inlet of the vacuum pipe;

[0016] The information of two adjacent flight images is merged, and the debris features and their locations in the images are obtained by matching the merged flight image information with a preset debris database.

[0017] Determine the debris injection angle and debris injection position based on the characteristic location of the debris;

[0018] The debris injection velocity is determined based on the shooting interval and the location of the debris characteristics.

[0019] The impact location type is determined based on the dust injection speed, the dust injection location, and the preset straight section length of the suction pipe. The impact location type includes straight section impact and curved section impact.

[0020] Based on the impact of the straight pipe section, the suction pipe is controlled to correct the flight path of the flying debris through the straight pipe section using a preset airflow control method.

[0021] Based on the impact of the bend in the pipe section, the suction pipe is controlled to correct the flight path of the flying debris using a preset rebound control method so that it can pass through the bend in the pipe section.

[0022] Optionally, the suction pipe has a ring of nozzles at the inlet, which spray air into the suction pipe to adjust the flight direction of flying debris within the suction pipe; the airflow control method includes:

[0023] The nozzles are numbered sequentially in circumferential order, with each nozzle corresponding to a specific nozzle number;

[0024] Determine whether the debris is injected into the preset impact range;

[0025] If it does not fall in, determine the nozzle number of the nozzle directly opposite it based on the location where the flying debris enters;

[0026] The nozzle's spray angle is determined based on the angle at which the flying debris enters.

[0027] According to the nozzle number, the nozzle is controlled by the spray angle to spray air onto the flying debris at the point where the flying debris is injected, so as to adjust the flying debris to the center of the suction pipe.

[0028] Reset the nozzles and control all nozzles to spray air into the suction pipe at a preset spiral jet angle to form a spiral airflow and carry the flying debris through the straight pipe section;

[0029] If it falls in, the rebound path of the flying debris in the vacuum pipe is determined based on the angle and position of the flying debris entry;

[0030] The rebound time of the flying debris to the center of the suction pipe is determined based on the rebound path and the speed at which the flying debris is injected.

[0031] Based on the rebound time, all nozzles are controlled to spray air into the suction pipe at a preset spiral jet angle to form a spiral airflow and carry the flying debris through the straight pipe section.

[0032] By adopting the above technical solution, and by setting up a nozzle, the nozzle can blow air into the dust collection pipe to change the flight path of the dust, making it less likely for the dust to collide with the inner wall of the straight pipe section after entering the dust collection pipe. Furthermore, when the flight path of the dust is adjusted to the center of the straight pipe section, the nozzle can spray air to form a spiral airflow, which can carry the dust horizontally through the straight pipe section.

[0033] Optionally, a deformation device is fitted on the outer side of the bend section to drive deformation of the inner wall of the bend section, and the rebound control method includes:

[0034] The impact point of the flying debris on the curved section of the pipe is determined based on the angle and location of the flying debris, as well as the preset parameters of the suction pipe.

[0035] Determine the inner wall angle information of the bend section based on the impact location;

[0036] The angle of the rebound plane is determined based on the angle of entry of the flying debris;

[0037] Calculate the difference between the rebound plane angle and the inner wall angle, and define it as the adjustment angle;

[0038] The deformation device, which adjusts the angle, deforms the inner wall of the bend at the impact point so that the flying debris can bounce back and pass through the bend in one go.

[0039] By adopting the above technical solution and setting up a deformation device, the deformation device can adjust the angle of the inner wall surface of the bend section according to the flying debris parameters, so that when the flying debris hits the inner wall of the bend section and bounces back, the flying debris can pass through the bend section in one bounce, thus minimizing the damage caused by the flying debris to the bend section.

[0047] Optional, also includes:

[0048] Obtain surface image information of the inner wall of the vacuum cleaner tube;

[0049] The type of damage to the inner wall is determined by comparing the surface image information with the preset reference image information. The types of damage to the inner wall include scratches.

[0050] Based on the scratches on the inner wall, the scratch features and locations are determined according to the surface image information and the preset scratch database.

[0051] Determine the starting point and path of the scratch based on its location;

[0052] Determine the nozzle number and spray angle between the nozzle and the scratch starting point position based on the location of the scratch.

[0053] According to the nozzle number, control the nozzle to switch to liquid spraying function and spray filling liquid at the starting position of the scratch at the spray angle. After the preset spray time, control the nozzle to switch to air spraying function and spray air onto the scratch features along the scratch path. Control the preset polishing device to polish the hole position.

[0054] Optional, also includes:

[0055] Obtain surface image information of the inner wall of the vacuum cleaner tube;

[0056] The type of damage to the inner wall is determined by comparing the surface image information with the preset reference image information. The type of damage to the inner wall includes internal wall debris adhesion.

[0060] The jet velocity of each nozzle is determined based on the jet spacing value;

[0061] Based on the spray angle and air velocity, each nozzle is controlled to spray air at a preset vibration frequency onto the attachment site to vibrate the attachment site and dislodge the debris.

[0062] Secondly, this application provides a chip removal system for a laser cutting machine, which adopts the following technical solution:

[0063] A chip removal system for a laser cutting machine, comprising:

[0064] The acquisition module is used to acquire physical characteristic image information of materials, flight image information of flying debris, and surface image information of the inner wall of the suction pipe;

[0065] A memory for storing a program for a chip removal method for a laser cutting machine;

[0066] The processor can load and execute programs in memory to implement a chip removal method for laser cutting machines.

[0067] In existing technologies, debris generated by the equipment is typically directly sucked up through a suction pipe. However, because the debris flies around when it is generated, the final dust removal effect of the suction pipe is not ideal. In this solution, the debris is processed simultaneously by the suction pipe and the air blowing device. The air blowing device's air wall can blow air to form an air wall to prevent the flying debris from flying around and guide the debris. Then, the air blowing port can blow the flying debris towards the suction pipe, thereby improving the dust removal and chip removal capacity of the suction pipe, making the laser cutting machine cleaner, and preventing the debris from affecting the laser cutting machine's cutting effect on materials, thus improving the cutting quality of the product.

[0068] Thirdly, this application provides a laser cutting machine, which adopts the following technical solution:

[0069] A laser cutting machine, employing a chip removal method, further includes a laser control mechanism and a laser processing head; the laser control mechanism includes a first housing, a first reflecting mirror, a waveplate, and a beam expander assembly sequentially disposed within the cavity of the first housing along the optical path transmission direction; the laser processing head includes a second housing, a CCD assembly disposed outside the second housing, and a second reflecting mirror, a third reflecting mirror, and a focusing mirror disposed within the cavity of the second housing along the optical path transmission direction; the beam expander assembly faces the second reflecting mirror; the back of the CCD assembly faces the back of the third reflecting mirror.

[0070] By adopting the above technical solution, the laser can be directly reflected by the first reflecting mirror after it is generated, which reduces the energy loss during the propagation process. Furthermore, by setting up waveplates, beam expander components, and focusing mirrors, the laser optical path adjustment accuracy is higher, enabling the processing of more precise products.

[0071] Optionally, the beam expander assembly includes a beam expander and a three-dimensional mount installed in the inner cavity of the first housing for mounting and adjusting the position of the beam expander; the three-dimensional mount includes a vertical drive seat and a horizontal drive seat connected to the vertical drive seat, and the beam expander passes through the horizontal drive seat; the vertical drive seat is provided with a vertical screw that drives the horizontal drive seat to move vertically; adjacent sidewalls of the horizontal drive seat are respectively provided with a transverse screw that drives the beam expander to move laterally and a longitudinal screw that drives it to move longitudinally.

[0072] In summary, this application includes at least one of the following beneficial technical effects:

[0073] 1. The dust collection pipe and the air blowing device simultaneously process the debris. The air blowing device can blow air to form an air wall to prevent the flying debris from splashing around and guide the flying debris. Then the air blowing port can blow the flying debris towards the direction of the dust collection pipe, thereby improving the dust removal and chip removal ability of the dust collection pipe, making the laser cutting machine cleaner and the debris less likely to affect the laser cutting machine's cutting effect on materials, thus improving the cutting quality of the product.

[0074] 2. By setting up nozzles, the nozzles can blow air into the dust collection pipe to change the flight path of the dust, making it less likely for the dust to collide with the inner wall of the straight pipe section after entering the dust collection pipe. Furthermore, when the flight path of the dust is adjusted to the center of the straight pipe section, the nozzles can spray air to form a spiral airflow, which can carry the dust horizontally through the straight pipe section;

[0075] 3. After the laser is generated, it can be reflected directly by the first reflecting mirror, reducing energy loss during propagation. Furthermore, by setting up waveplates, beam expander components, and focusing mirrors, the laser optical path adjustment precision is improved, enabling the processing of more accurate products.

[0084] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0085] This application discloses a laser cutting machine.

[0086] Reference Figure 1 and Figure 2 A laser cutting machine includes a laser device for cutting metal materials and a chip removal device for cleaning up the chips generated during the cutting process.

[0087] The laser device includes a laser control mechanism 1 and a laser processing head 2. The laser control mechanism 1 includes a first housing 11, a first reflecting mirror 12, a waveplate 13, and a beam expander assembly 14 sequentially disposed within the cavity of the first housing 11 along the optical path transmission direction. The laser processing head 2 includes a second housing 21, a CCD assembly 22 disposed outside the second housing 21, and a second reflecting mirror 23, a third reflecting mirror 24, and a focusing mirror 25 disposed within the cavity of the second housing 21 along the optical path transmission direction.

[0088] The first reflector 12, the second reflector 23, and the third reflector 24 are all set at a 25° angle, with the mirror surfaces of the first reflector 12 and the second reflector 23 facing each other, and the mirror surface of the second reflector 23 facing the mirror surface of the third reflector 24. The beam expander assembly 14 is located between the first reflector 12 and the second reflector 23, directly facing the second reflector 23. The back of the CCD assembly 22 faces the back of the third reflector 24.

[0089] The laser control mechanism 1 is connected to the laser emitter. The laser generator produces laser light, which is reflected by the first reflector 12 and then passes through the wave plate 13 and the beam expander assembly 14 in sequence. After that, it is reflected by the second reflector 23 and the third reflector 24 in sequence, and finally focused on the material to be cut by the focusing lens 25, thereby cutting the material.

[0090] To observe the material cutting process and facilitate real-time laser control, the laser light illuminating the material can be reflected back and passed through the third reflecting mirror 24 to be received by the CCD component 22. The CCD component 22 includes a filter 221, a CCD lens 222, and a CCD camera 223. The light passes through the filter 221, the CCD lens 222, and the CCD camera 223 in sequence, and the CCD camera 223 can capture and analyze the light.

[0091] Reference Figure 3 The beam expander assembly 14 can adjust the laser path. The beam expander assembly 14 includes a beam expander 141 and a three-dimensional mount 142. The three-dimensional mount 142 is connected inside the first housing 11 and is used for mounting and adjusting the beam expander 141. The three-dimensional mount 142 includes a vertical drive seat 1421 and a horizontal drive seat 1422 connected to the vertical drive seat 1421. The vertical drive seat 1421 is provided with a vertical screw 1423 that drives the horizontal drive seat 1422 to move vertically. By rotating the vertical screw 1423, the horizontal drive seat 1422 can move vertically. Adjacent sidewalls of the horizontal drive seat 1422 are respectively provided with a transverse screw 1424 that drives the beam expander 141 to move laterally and a longitudinal screw 1425 that drives it to move longitudinally. By selecting the transverse screw 1424 and the longitudinal screw 1425, the beam expander 141 can move horizontally.

[0092] Reference Figure 1The chip removal device is connected to the second housing 21. The chip removal device includes an air blowing device 3 for blowing air and a dust suction pipe 4 for vacuuming. The air blowing device 3 is directly opposite the dust suction pipe 4 and can blow the chips generated during the material cutting process into the dust suction pipe 4.

[0093] Based on the same inventive concept, this invention provides a chip removal method for a laser cutting machine. A blowing device 3 blows the flying chips generated during the cutting process towards a suction pipe 4, which then sucks in the chips and transports them out of the laser cutting machine. The suction pipe 4 can be adjusted to guide the flight path of the chips according to their trajectory, ensuring they pass through with minimal impact. After dust removal is complete, the system can repair any damage caused by the chips impacting the suction pipe 4.

[0094] In this embodiment, the air blowing device 3 has an air blowing port 31 and an air wall port 32, with the air wall port 32 located on both sides of the air blowing port 31. The air blowing port is used to blow the debris generated during the cutting process into the dust suction pipe 4. The air wall port 32 is used to blow air on both sides of the laser focusing point of the laser cutting machine to form two parallel air walls, which are used to block the flying debris and guide it into the dust suction pipe 4.

[0095] A nozzle 41 is circumferentially arranged at the inlet of the suction pipe 4, with the nozzle 41 facing the inside of the suction pipe 4. The nozzle 41 has both air spray and liquid spray functions, which can be switched.

[0096] Reference Figure 4 A method for removing chips from a laser cutting machine includes the following steps:

[0097] Step S100: At the preset processing position, acquire the material's physical characteristics image information.

[0098] The processing position is located inside processing chamber 2, at the laser focus of the laser cutting machine. The material to be processed is fixed at the processing position and cut by the laser.

[0099] Visible image information refers to the image information of the material's shape and contour. This information is acquired through a camera installed inside the laser cutting machine. There is a one-to-one correspondence between the material's vital image information and the resulting product; each type of material's vital image information corresponds to one type of product.

[0100] Step S101: Match the vital sign image information with the preset product database to determine the product processing information.

[0101] The product database is a database created by humans, which contains a one-to-one correspondence between the physical characteristics and image information of materials and the product information that can be cut into them. The product database will not be described in detail here.

[0102] Because each shape of material can only be cut into specific products, once the camera captures an image of the material, by comparing the image information with a product database, it is possible to match the corresponding product information that can be processed into.

[0103] Step S102: Determine the product cutting path information based on the product processing information.

[0104] Cutting path information refers to the path the laser travels on a material when a laser cutting machine cuts it. A specific product corresponds to a specific cutting method; therefore, the cutting path information is unique for each product. The laser cutting path information can be directly matched from the system using the product processing information.

[0105] Step S103: Determine the direction of the flying debris generated at the laser focus point based on the cutting path information.

[0106] Once the cutting path information is determined, the direction of the cutting plane at any position along the cutting path can also be determined. When a laser cutting machine cuts material, most of the flying debris generated during cutting splashes towards the direction of the cutting plane. Therefore, the direction of the flying debris splashes corresponds to the direction of the cutting plane at the corresponding position in the cutting path information, and the direction of the flying debris splashes can be determined through the cutting path information.

[0107] Step S104: Determine the suction direction of the preset suction pipe 4, the blowing direction of the preset air blowing device 3 air outlet 31, and the air wall direction of the air wall outlet 32 ​​according to the direction of debris splashing.

[0108] The suction direction is the orientation of the opening of the suction pipe 4. The orientation angle of the suction pipe 4 can change with the change of the splash direction, and the suction direction is always parallel to the splash direction. The blowing direction is the orientation of the air outlet 31 of the blowing device 3, and the wind wall direction is the direction of the wind wall formed when the air outlet 32 ​​of the blowing device 3 blows air. Both the blowing direction and the wind wall direction are the same as the splash direction of the flying debris.

[0109] Step S105: Control the suction pipe 4 to suck up the flying debris according to the suction direction, and control the blowing device 3 to blow the debris on the material surface into the suction pipe 4 according to the blowing direction. Simultaneously control the blowing device 3 to blow air in the direction of the air wall on both sides of the laser focusing point to form an air wall to limit the flying debris and guide the flying debris into the suction pipe 4.

[0110] When the material is cut, the resulting debris can splash between the parallel wind walls on both sides and enter the suction pipe 4. The debris that falls near the laser focal point can be blown into the suction pipe 4 by the air outlet 31 of the air blowing device 3. Some of the debris that splashes around during the cutting process can also be blocked by the wind walls and carried into the suction pipe 4 by the wind walls.

[0111] Reference Figure 5 The vacuum cleaner hose 4 has straight and curved sections. When dust particles enter the vacuum cleaner hose 4, they will collide with the interior of the hose, potentially causing damage. Therefore, it is necessary to distinguish the impact location of the dust particles in order to address the issue accordingly. The method for distinguishing the impact location type includes the following steps:

[0112] Step S200: Acquire flight image information of flying debris at the inlet of the suction pipe 4 within a preset shooting interval.

[0113] The flight position and attitude of the flying debris when it enters the suction pipe 4 determine the collision position between the flying debris and the suction pipe 4 when the flying debris moves inside the suction pipe 4.

[0114] The flight image information refers to the images of flying debris at the inlet of the suction pipe 4, captured by the camera. When flying debris appears at the inlet of the suction pipe 4, the camera continuously captures images of the debris at preset shooting intervals. The shooting interval is a fixed value set manually and will not be elaborated here. Flying debris is present in each captured image, and due to the time interval, the same flying debris will be in different positions in different images.

[0115] Step S201: Merge the information of two adjacent flight images, and match the merged flight image information with the preset debris database to obtain the debris features and debris feature locations in the image.

[0116] By overlaying and merging two adjacent images, two pieces of the same debris located in different positions can appear simultaneously in one image. Matching the merged image with a debris database then allows us to find two debris features within the image and determine the two locations of the same debris feature at different time points.

[0117] Step S202: Determine the flying debris injection angle and the flying debris injection position based on the characteristic position of the flying debris.

[0118] The dust ejection position refers to the position of the dust particles at the inlet of the suction pipe 4 at the instant they enter. The dust ejection angle refers to the angle of the dust particles relative to the inlet of the suction pipe 4 at the instant they enter. Both the dust ejection angle and the dust ejection position affect the impact point of the dust particles against the inner wall of the suction pipe 4 as they fly through it.

[0119] The flight image information includes images of the inlet of the suction pipe 4 and debris features. Therefore, the entry point of debris at the inlet of the suction pipe 4 can be determined using the flight image information. The suction pipe 4 is horizontally positioned, and the debris entry angle can be calculated by calculating the positions of two debris features at different time points.

[0120] Step S203: Determine the debris injection speed based on the shooting interval and the location of the debris characteristics.

[0121] The dust ejection velocity refers to the speed at which dust particles enter the suction pipe 4. The dust ejection velocity can be calculated based on the distance between two characteristic positions of dust particles at different time points and the shooting interval.

[0122] Step S204: Determine the impact position type based on the flying debris injection speed, flying debris injection position, and the preset straight pipe length of the suction pipe 4. The impact position type includes straight pipe impact and curved pipe impact.

[0123] The length of the straight section of the suction pipe 4 is a fixed value set manually and will not be elaborated here. Based on the dust injection velocity, dust injection position, and the length of the straight section of the suction pipe 4, calculations can determine whether the dust can pass through the straight section and enter the curved section, thus determining the impact type of the dust as straight section impact or curved section impact. Straight section impact refers to the dust impacting the inner wall of the straight section after entering the suction pipe 4. Curved section impact refers to the dust impacting the inner wall of the curved section after entering the suction pipe 4. Different targeted solutions are used to handle these two situations.

[0124] Step S205: Based on the impact of the straight pipe section, control the suction pipe 4 to correct the flight path of the flying debris using a preset airflow control method so that it can pass through the straight pipe section.

[0125] For the type of impact in straight pipe sections, after the flying debris enters the suction pipe 4, the flight path of the debris is corrected through airflow control methods to prevent it from impacting the inner wall of the straight pipe section. The airflow control method will not be elaborated here, but will be described in detail in a subsequent section.

[0126] Step S206: Based on the impact of the bend, control the suction pipe 4 to correct the flight path of the flying debris using a preset rebound control method so that it can pass through the bend.

[0127] For impacts occurring in bends, after the flying debris passes through the straight section and enters the bend, a rebound control method is used to correct its flight path. Because the bend is a curved section, flying debris is unlikely to pass through without any impact. Therefore, a rebound control method is used to control the flying debris, ensuring it passes through the bend with the minimum number of impacts allowed. The rebound control method will not be elaborated here but will be described in detail in a subsequent section.

[0128] Reference Figure 6 The airflow control method includes the following steps:

[0129] Step S300: Number the nozzles 41 sequentially in circumferential order, with each nozzle 41 corresponding to a specific nozzle number.

[0130] The airflow control method is implemented by controlling the nozzles 41. Since there are a large number of nozzles 41, each nozzle 41 is numbered for more precise airflow control. When controlling the nozzles 41, the nozzles 41 are controlled according to their corresponding numbers.

[0131] Step S301: Determine whether the flying debris falls within the preset impact range at the injection point.

[0132] The impact range is a reference value set by humans and will not be elaborated here. When the flying dust enters the dust pipe within the impact range, due to the small distance between the flying dust and the inner wall of the straight pipe section, the flying dust will still collide with the inner wall of the straight pipe section after entering the dust suction pipe 4, even if the direction of the flying dust is controlled by airflow.

[0133] By comparing the location where the debris is injected with the impact range, it can be determined whether the debris will impact the inner wall of the straight pipe section.

[0134] Step S3011: If it does not fall in, determine the nozzle number of the nozzle 41 directly opposite it based on the location of the flying debris. 。

[0135] If the flying debris does not fall within the impact range, when it enters the suction pipe 4, it can be directly sprayed through the nozzle 41 to change its direction. The nozzle number is determined based on the location where the flying debris enters, and the nozzle 41 closest to the location is selected.

[0136] When the dust enters the suction pipe 4, it is blown by a specific nozzle 41. By changing the flight angle of the dust, the dust can be moved to the center of the suction pipe 4.

[0137] Step S30111: Determine the spray angle of nozzle 41 based on the angle of entry of flying debris.

[0138] The spray angle refers to the angle at which the nozzle 41 sprays air onto the flying debris. The spray angle of the nozzle 41 can be determined based on the angle at which the flying debris enters the nozzle, and the spray angle corresponds one-to-one with the angle at which the flying debris enters the nozzle.

[0139] Step S30112: According to the nozzle number, control the nozzle 41 to spray air at the flying debris injection position according to the spray angle to adjust the flying debris to the center of the suction pipe 4.

[0140] After determining the appropriate nozzle 41 and spray angle, control the nozzle 41 to spray air onto the flying debris, so that the flight path of the flying debris is twisted towards the center of the suction pipe 4 until the flying debris reaches the central axis of the suction pipe 4.

[0141] Step S30113: Reset the nozzle 41 and control all nozzles 41 to spray air into the suction pipe 4 at a preset spiral jet angle to form a spiral airflow and carry the flying debris through the straight pipe section.

[0142] The spiral jet angle is a value set by the technicians and will not be elaborated here. Nozzles 41 are uniformly tilted to the spiral jet angle to spray air, at which time a spiral airflow can be formed in the straight pipe section.

[0143] When the flying debris reaches the center axis of the straight pipe section, the corresponding nozzle 41 is reset. After resetting, all nozzles 41 are tilted to the spiral jet angle to blow air, so that the flying debris can be carried horizontally through the straight pipe section by the spiral airflow.

[0144] Step S3012: If it falls in, determine the rebound path of the flying debris in the suction pipe 4 according to the angle and position of the flying debris.

[0145] When the flying debris enters the impact range, from the moment it enters the suction pipe 4 to the moment it impacts the inner wall of the straight pipe section, the nozzle 41 does not need to control the path of the flying debris; it only needs to control the flight path of the flying debris after it bounces back.

[0146] The bounce path refers to the flight path of debris after it impacts and bounces off the inner wall of a straight pipe section. The bounce path can be determined based on the debris's entry angle and entry position. By determining the debris's entry angle and entry position, the impact location on the inner wall of the straight pipe section can be first established. Then, based on the entry angle and the principle of bounce, the flight path of the debris after impact and bounce can be obtained.

[0147] Step S30121: Determine the rebound time of the flying debris to the center of the suction pipe 4 based on the rebound path and the speed of the flying debris injection.

[0148] The rebound time refers to the time it takes for the flying debris to reach the center of the straight pipe section after rebounding. The distance from the rebound path to the center of the straight pipe section can be determined, and then the rebound time can be calculated using the distance-velocity formula.

[0149] Step S30122: Based on the rebound time, control all nozzles 41 to spray air into the suction pipe 4 at a preset spiral jet angle to form a spiral airflow and carry flying debris through the straight pipe section.

[0150] Timing begins when the dust enters the suction pipe 4. After the rebound time interval, the nozzle 41 adjusts its angle to the spiral jet angle and sprays air. At this time, the dust that reaches the center of the straight pipe section can be carried by the spiral airflow and pass horizontally through the straight pipe section.

[0151] Reference Figure 7 The rebound control method includes the following steps:

[0152] Step S400: Determine the impact position of the flying debris on the curved section of the pipe based on the flying debris injection angle, flying debris injection position, and preset suction pipe parameters 4.

[0153] The four parameters of the vacuum cleaner hose include the length of the straight section, the curvature and radius of the curved section, etc. These four parameters are manually set values ​​and will not be elaborated here. Based on the dust injection angle, the dust injection position, and the four parameters of the vacuum cleaner hose, the position where the dust passes through the straight section and impacts the curved section can be calculated.

[0154] Step S401: Determine the inner wall angle information of the bend section based on the impact location.

[0155] Once the impact point of the flying debris on the inner wall of the bend section is determined, the tangential angle of the bend section at the impact point can be determined based on the impact point and the bend section parameters of the suction pipe 4. The inner wall angle information refers to the tangential angle of the flying debris at the impact point on the inner wall of the bend section.

[0156] Step S402: Determine the angle of the rebound plane based on the angle of the flying debris injection.

[0157] When the dust particles can pass through the bend after one bounce, the angle of the tangential plane at the point of impact between the dust particles and the inner wall of the bend is the bounce plane angle. When the impact point is at the bounce plane angle, the dust particles can pass through the bend after one bounce upon impact. The bounce plane angle can be determined based on the dust particle injection angle and the bend parameters of the suction pipe 4.

[0158] Step S403: Calculate the difference between the rebound plane angle and the inner wall angle information, and define it as the adjustment angle.

[0159] If the angle of the rebound plane is inconsistent with the angle of the inner wall, the angle of the inner wall needs to be adjusted based on the angle of the rebound plane. The adjustment angle is the amount of adjustment to the inner wall angle, which is the difference between the angle of the rebound plane and the angle of the inner wall.

[0160] Step S404: Adjust the angle to control the deformation device to deform the inner wall of the bend at the impact position so that the flying debris can pass through the bend in one go after rebounding.

[0161] The deformation device is fitted on the outside of the bend section to drive the bend section to deform, thereby changing the angle of the inner wall of the bend section.

[0162] When the flying debris enters the suction pipe 4, the system can control the deformation device according to the adjustment angle. The deformation device drives the impact position of the bend section and the flying debris to deform, so that the flying debris can pass through the bend section in one go after hitting the impact position and rebounding.

[0163] If the rebound control method still cannot control the flying debris to pass directly through the bend section after one impact, it indicates that the bending angle of the bend section is too large or the number of bends in the bend section is too large. At this time, the bend section is straightened by the preset straightening device, so that the bending angle or the number of bends in the bend section is reduced.

[0164] When controlling dust particles using the aforementioned airflow control and rebound control methods, some dust particles may still impact the inner wall of the suction pipe 4. Since the dust particles are formed at high temperatures, this impact can damage the interior of the suction pipe 4. The main types of damage to the inner wall of the suction pipe 4 include inner wall burns, inner wall scratches, and debris adhesion. Inner wall burns refer to dust particles impacting and burning the inner wall of the suction pipe 4, creating a hole. Inner wall scratches refer to dust particles impacting and sliding along the inner wall of the suction pipe 4, causing scratches. Inner wall debris adhesion refers to dust particles impacting and embedding in the inner wall of the suction pipe 4.

[0165] There are specific solutions for each of the three situations mentioned above, and the laser cutting machine is not in operation during the process.

[0166] The treatment method for burns on the inner wall of the vacuum cleaner hose 4 includes the following steps:

[0167] Step S500: Obtain surface image information of the inner wall of the suction pipe 4.

[0168] The surface image information refers to the image information of the inner wall of the suction pipe 4, including the inner wall images of the straight pipe section and the inner wall images of the curved pipe section. The surface image information is acquired by a camera that can extend into the suction pipe 4.

[0169] Step S501: Determine the type of inner wall damage based on the comparison between the surface image information and the preset reference image information. The types of inner wall damage include inner wall burns.

[0170] The baseline image information refers to the image information of the inner wall of the suction pipe 4 under undamaged conditions, which serves as a reference value and will not be elaborated upon here.

[0171] By comparing surface image information with reference image information, the location of damage in the surface image information can be determined. Then, by comparing the image of the damage location with a pre-defined damage type database, the damage type can be determined. The damage type database is a database obtained through machine learning and includes images of various damage types, which will not be elaborated upon here.

[0172] Step S502: Based on the inner wall burns, determine the hole characteristics and hole location according to the surface image information and the preset hole database.

[0173] The hole database is a database obtained through machine learning, containing image information of various holes, which will not be elaborated here.

[0174] By comparing the surface image information with the hole database, the hole features can be found and the location of the hole on the inner wall of the suction pipe 4 can be determined.

[0175] Step S503: Determine the corresponding opening position on the outer wall of the suction pipe 4 based on the location of the hole.

[0176] The perforation feature penetrates both the inside and outside of the suction pipe 4, therefore the outer wall of the suction pipe 4 has an opening feature corresponding to the perforation feature on the inner wall. The opening position is the location of the opening feature on the outer wall of the suction pipe 4.

[0177] The location of the hole can be used to determine the opening position on the outer wall of the suction pipe 4.

[0178] Step S504: Determine the nozzle number of the nozzle 41 corresponding to the location of the hole and the spray angle between the hole location and the nozzle 41.

[0179] The nozzle 41 corresponding to the hole location refers to the nozzle 41 farthest from the hole location, and this nozzle 41 is symmetrically arranged with the nozzle 41 closest to the hole location.

[0180] The spray angle refers to the angle at which the nozzle 41 sprays the filling fluid at the location of the puncture. The spray angle can be determined based on the nozzle position and the location of the puncture.

[0181] In this embodiment, when the nozzle 41 sprays the filling liquid, the nozzle 41 switches to the liquid spraying function, at which time it can spray the filling liquid.

[0182] Step S505: According to the opening position, control the preset tape to seal the opening position, control the nozzle 41 to switch to the liquid spraying function according to the nozzle number and spray the filling liquid to the hole position at the spraying angle, control the nozzle 41 to switch to the air spraying function after the preset spraying time and spray the hole position, and control the preset grinding device to grind the hole position.

[0183] When there is a hole in the inner wall of the suction pipe 4, the system can control the robotic arm to seal the opening with tape, then switch the nozzle 41 to the liquid spraying function and spray filling liquid onto the hole. Then switch the nozzle 41 back to the air spraying function and spray air onto the hole. The filling liquid can quickly solidify under the action of airflow, thereby sealing the hole. Finally, the grinding device extends into the suction pipe 4 and grinds the hole to make the repaired hole smooth.

[0184] The spraying time is a fixed value set by the user. The spraying time controls the nozzle 41 to spray the filling liquid, which can fill the hole.

[0185] The repair method for scratches on the inner wall of the vacuum cleaner hose includes the following steps:

[0186] Step S600: Obtain surface image information of the inner wall of the suction pipe 4.

[0187] The same as step S500, so it will not be repeated here.

[0188] Step S601: Determine the type of damage to the inner wall based on the comparison between the surface image information and the preset reference image information. The types of damage to the inner wall include scratches on the inner wall.

[0189] Similar to step S501, the damage location image can be obtained by comparing the surface image information and the reference image information, and the damage type can be determined by comparing the damage location image with the damage type database.

[0190] Step S602: Based on the scratches on the inner wall, determine the scratch features and scratch locations according to the surface image information and the preset scratch database.

[0191] The scratch database is a database obtained through machine learning, containing image information of scratches, which will not be elaborated on here.

[0192] By comparing the surface image information with the scratch database, the scratch features can be found and the location of the scratch on the inner wall of the suction tube 4 can be determined.

[0193] Step S603: Determine the starting point and path of the scratch based on the location of the scratch.

[0194] The scratch initiation point refers to the location of the point on the scratch feature closest to the inlet of the suction pipe 4. The scratch path refers to the curved route generated based on the shape of the scratch. Both the scratch initiation point and the scratch path can be determined from the image of the scratch location in the surface image information.

[0195] Step S604: Determine the nozzle number of the corresponding nozzle 41 and the spray angle between the scratch start position and the nozzle 41 based on the scratch start position.

[0196] The same as step S504, so it will not be repeated here.

[0197] Step S605: Control the nozzle 41 to switch to liquid spraying function according to the nozzle number and spray filling liquid at the starting position of the scratch at the spray angle. After the preset spraying time, control the nozzle 41 to switch to air spraying function and spray air onto the scratch features along the scratch path. Control the preset polishing device to polish the hole position.

[0198] When scratches are present on the inner wall of the suction pipe 4, the system can switch a specific nozzle 41 to liquid spraying function and spray filling liquid at the starting point of the scratch. Then, the nozzle 41 is switched back to air spraying function, where it sprays air at the starting point of the scratch and moves along the scratch path. This allows the filling liquid to move along the scratch path under the action of airflow, thus filling the entire scratch groove. During the movement, the filling liquid solidifies rapidly due to the continuous airflow from the nozzle 41. Finally, a polishing device is inserted into the suction pipe 4 to polish the scratched area, making the repaired scratch features smooth.

[0199] The method for removing debris adhering to the inner wall of the vacuum cleaner hose 4 includes the following steps:

[0200] Step S700: Obtain surface image information of the inner wall of the suction pipe 4.

[0201] The same as step S500, so it will not be repeated here.

[0202] Step S701: Determine the type of damage to the inner wall based on the comparison between the surface image information and the preset reference image information. The type of damage to the inner wall includes the attachment of debris to the inner wall.

[0203] Similar to step S501, the damage location image can be obtained by comparing the surface image information and the reference image information, and the damage type can be determined by comparing the damage location image with the damage type database.

[0204] Step S702: Based on the adhesion of debris to the inner wall, determine the adsorption position of debris in the suction pipe 4 according to the surface image information and the preset debris database.

[0205] The debris database is a manually set database and will not be described in detail here. By matching the surface image information with the debris database, the debris can be located and its adsorption position on the inner wall of the suction pipe 4 can be determined.

[0206] Step S703: Calculate the spray angle of the adsorption position and the preset nozzle position of each nozzle 41.

[0207] The spray angle refers to the angle at which the nozzle 41 sprays air towards the adsorption position. The angle between the adsorption position and the position of each nozzle 41 can be determined by the adsorption position and the position of the nozzle 41.

[0208] Step S704: Determine the spray spacing value between each nozzle 41 and the adsorption position based on the adsorption position and the nozzle 41 position.

[0209] The spray spacing value is the distance between the adsorption position and the nozzle 41.

[0210] Step S705: Determine the jet velocity of each nozzle 41 based on the jet spacing value.

[0211] In this embodiment, the system controls all nozzles 41 to blow air onto the adsorption position simultaneously, and the airflow reaches the adsorption position at the same time, causing the airflow to vibrate the adsorption position. The vibration shakes off the debris at the adsorption position, and finally the debris is sucked away by the suction pipe 4.

[0212] Since the spray distance from each nozzle 41 to the adsorption position is not the same, the jet velocity of each nozzle 41 is also different in order to ensure that the airflow generated by each nozzle 41 reaches the adsorption position synchronously. The jet velocity is related to the spray distance value, and the jet velocity can be determined by the spray distance value.

[0213] Step S706: Control each nozzle 41 to spray air at a preset vibration frequency to the attachment position according to the spray angle and air speed, so as to vibrate the attachment position and shake off the debris.

[0214] In this embodiment, the airflow from nozzle 41 is not continuous but intermittent, and the frequency of the airflow from nozzle 41 is the vibration frequency. Through intermittent airflow, the airflow blowing on the adsorption position can cause the adsorption position to vibrate.
