Description

Technical Field

[0001] This invention relates to the field of electric vehicle frame processing, and in particular to a laser cutting production apparatus and control method for electric vehicle frame tubes. Background Technology

[0002] Laser cutting of electric vehicle frames is a highly efficient manufacturing process that is widely used in the electric vehicle manufacturing industry. This technology uses a high-energy-density laser beam to cut metal tubing.

[0003] During the cutting process of electric vehicle frame tubes, the frame tubes need to be clamped and positioned before laser cutting. During the cutting process, the cut part of the tube will generate debris. If the debris falls into the clamping position of the tube, it will cause the clamping of the tube to shift, resulting in deviation of the laser cutting of the tube and thus affecting the processing efficiency of the tube. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a laser cutting production device and control method for electric vehicle frame tubes.

[0005] In a first aspect, the present invention provides a laser cutting production apparatus for electric vehicle frame tubing, comprising a processing table, wherein a laser cutting frame is installed inside the processing table, and further comprising:

[0006] The housing is fixed inside the processing table by a support plate;

[0007] A rotating cylinder is rotatably mounted on the top of the housing and driven by a rotation drive assembly. A notch is provided inside the rotating cylinder.

[0008] A clamping and feeding assembly is installed inside the notch and is used to clamp and transport the pipe fittings that enter the notch after clamping.

[0009] A conveying assembly, mounted on the rotating drum, is used for loading and unloading pipe fittings into the recess.

[0010] A cleaning component, installed on the side of the support plate, is used to clean debris from the surface of the laser-processed pipe and to reduce debris from entering the recess by isolating it.

[0011] The tube is conveyed to the notch via a conveying assembly. After being conveyed above the notch, the tube enters the notch. Once inside, the clamping and feeding assembly is activated to clamp the tube. After clamping, the clamping and feeding assembly drives the tube towards the laser cutting frame, causing the end of the tube to extend into the laser cutting frame. The laser cutting frame then cuts the tube at one end. After one end is cut, a cleaning assembly is activated. As the tube repositions into the notch, the cleaning assembly cleans debris from the cut end of the tube. The cleaning assembly isolates the laser cutting position from the notch, preventing debris from splashing into the notch and avoiding instability in the clamping. This helps prevent laser cutting deviations caused by unstable clamping.

[0012] After one end of the pipe is laser-cut, the clamping and feeding assembly is activated to convey and reset the pipe into the notch. Then, the rotation drive assembly drives the rotating cylinder to rotate, changing the direction of both ends of the pipe. Afterward, the clamping and feeding assembly is activated again to convey the other end of the pipe into the position of the laser cutting frame, so that the laser cutting frame can cut the other end of the pipe after starting. This achieves cutting of both ends of the pipe. Furthermore, the setting of the conveying assembly eliminates the need for manual feeding of the pipe, thereby improving the efficiency of laser cutting of the pipe.

[0013] Preferably, the conveying assembly includes:

[0014] The frame is fixed to the inner wall of the processing table;

[0015] A feeding conveyor belt is installed on one side of the frame body via a first conveying drive assembly;

[0016] The unloading conveyor belt is installed on the other side inside the frame via a second conveying drive assembly, with the feeding conveyor belt and the unloading conveyor belt located on opposite sides of the notch, respectively.

[0017] A guide frame is fixed to the inner wall of the processing table, and the guide frame is connected to the unloading conveyor belt;

[0018] A lifting drive assembly is installed inside the recess to drive the pipe to move up and down;

[0019] After the first conveying drive component starts, it drives the feeding conveyor belt to transport the pipe to the notch position. The feeding speed of the pipe is controlled by controlling the transmission frequency of the feeding conveyor belt. After the second conveying drive component starts, it drives the unloading conveyor belt to transport the cut pipe to the unloading position. The unloaded pipe slides down and is collected by the guide frame, thus realizing automatic loading and unloading of pipe. The lifting drive component can transport the pipe that reaches the notch position. When the lifting drive component transports the pipe to the lowest position of the notch, the clamping feeding component can clamp the pipe. When the lifting drive component transports the pipe to the highest position of the notch, the pipe can be pushed by the pipe on the feeding conveyor belt into the unloading conveyor belt for replacement.

[0020] Preferably, the lifting drive assembly includes:

[0021] The lifting platform is vertically slidably installed inside the recess;

[0022] The first cylinder is fixed inside the housing, and the end of the telescopic rod of the first cylinder is rotatably connected to the bottom center of the lifting platform.

[0023] After the first cylinder is started, it pushes the lifting platform to move vertically through the telescopic rod. The end of the telescopic rod of the first cylinder is rotatably connected to the lifting platform, so that the rotating cylinder can maintain the connection with the end of the telescopic rod of the first cylinder during the rotation of the lifting platform.

[0024] Preferably, the cleaning component includes:

[0025] A vertical plate is fixed to the side of the support plate, and a round hole for pipe fittings to pass through is opened in the middle of the vertical plate;

[0026] A threaded drive disc is rotatably mounted inside the circular hole and driven by a clamping drive assembly.

[0027] Multiple sliders are arranged in a circular array and are slidably connected to the threaded groove of the threaded drive disk through sliding contacts. The sliders are slidably connected to the vertical plate through straight rods. All the sliders have absorbent cotton and rubber scraper blocks fixed on the side facing away from the threaded drive disk. The absorbent cotton is located between the rubber scraper block and the slider.

[0028] The nozzle holder is fixed to the side wall of the vertical plate, and multiple nozzles are linearly fixed at the bottom of the nozzle holder;

[0029] A water delivery assembly, installed below the vertical plate, is used to store and deliver water to the nozzle;

[0030] The pipe passes through the circular hole in the middle of the vertical plate to the laser cutting frame for cutting. After cutting, the clamping and feeding assembly drives the pipe to retreat into the recess. At this time, the water flow delivery assembly is activated, supplying water to the nozzle, creating a water curtain. As the pipe passes through the water curtain, debris is cleaned from its surface, preventing it from entering the recess and interfering with clamping. This helps prevent instability in pipe clamping. Simultaneously, the clamping drive assembly is activated, driving the threaded drive disc to rotate. The rotating disc drives the slider through the threaded groove. The slider is slidably connected to the vertical plate via a straight rod, allowing the vertical plate to slide only along the trajectory of the straight rod. This causes all the sliders to move closer together to clamp the pipe. The sliders also bring the absorbent cotton and rubber scraper closer together to clamp the surface of the pipe. Once the pipe is clamped, the rubber scraper adheres to the surface of the pipe, removing water stains. When the pipe reaches the absorbent cotton, the cotton absorbs any residual moisture on the surface of the pipe. This helps prevent water from flowing into the recess and interfering with the clamping stability, thus preventing the accuracy of laser cutting from being affected by unstable clamping of the pipe.

[0031] Preferably, the cleaning component further includes:

[0032] A filter frame is fixed inside the processing table. A flip filter plate is rotatably mounted in the middle of the filter frame. A torsion spring is sleeved on the rotating shaft of the flip filter plate. The two ends of the torsion spring are fixedly connected to the flip filter plate and the filter frame, respectively.

[0033] The U-shaped pusher is vertically slidably connected to the filter frame, and when the U-shaped pusher moves vertically, it pushes the flip filter plate to flip.

[0034] A screw is rotatably mounted below the vertical plate, and the screw is threadedly connected to the U-shaped push frame. The clamping drive assembly is also used to drive the screw to rotate.

[0035] The worm gear of the clamping drive assembly rotates, driving the screw to rotate. After the screw rotates, it drives the U-shaped pusher frame, which is threaded to it, to move vertically. After the U-shaped pusher frame moves vertically, it pushes one end of the flip filter plate upward, causing the flip filter plate to flip. As the flip filter plate flips, under the action of the water flow from the nozzle, the debris on the inclined flip filter plate surface is flipped upward and cleaned. This helps to prevent debris from accumulating on the surface of the flip filter plate and interfering with laser cutting. At the same time, the flip filter plate can intercept and support falling debris, thus preventing the water splashed from falling debris from interfering with laser cutting.

[0036] Preferably, the clamping and feeding assembly includes:

[0037] Multiple clamping blocks are divided into two groups. The two groups of clamping blocks are inserted in a linear array on both sides of the notch. Each clamping block extends through the side of the notch and into the interior of the rotating cylinder.

[0038] Multiple electric telescopic rods, one electric telescopic rod corresponding to one clamping block, the electric telescopic rod is fixed inside the rotating cylinder, and the telescopic rod end of the electric telescopic rod is fixedly connected to the corresponding clamping block;

[0039] A feed drive assembly is installed on both sides of the notch to drive the pipe to move;

[0040] After the electric telescopic rod is started, the clamping block is moved by pushing the end of the telescopic rod, so that the clamping block extends into the inside of the notch to clamp the pipe, which helps to prevent the pipe from loosening or shifting during the laser cutting process.

[0041] Preferably, the feed drive assembly includes:

[0042] Multiple movable frames are divided into two groups and are slidably installed in a linear array inside the rotating cylinder. The two groups of movable frames are located on both sides of the notch.

[0043] The second cylinder is configured one-to-one with the movable frame and is fixed inside the rotating cylinder to drive the movable frame to move;

[0044] The drive roller is configured one-to-one with the movable frame and is rotatably mounted inside the movable frame. It is driven to rotate by the drive component mounted on the movable frame. The drive roller extends into the interior of the recess through the opening opened on the side wall of the recess.

[0045] After the second cylinder is started, it pushes the moving frame to move into the inside of the notch. The moving frame drives the drive roller to move through the opening into the inside of the notch, thereby adjusting the clamping force between the drive roller and the tube. The drive component drives the drive roller to rotate. After the drive roller clamps the tube to the required force, the rotation of the drive roller drives the tube to move, thereby driving the tube to achieve laser cutting at both ends of the tube.

[0046] Secondly, a control method for a laser cutting production device for electric vehicle frame components is provided. The processing table is equipped with a controller, a first pressure sensor is fixed to the top of the lifting platform, and a second pressure sensor is fixed to the bottom of the lifting platform. The control method includes the following steps:

[0047] The controller receives first pressure information acquired by the first pressure sensor;

[0048] The controller receives second pressure information acquired by the second pressure sensor;

[0049] When the controller receives both the first pressure information and the second pressure information simultaneously, it generates clamping control information based on the first pressure information and the second pressure information. The clamping control information is used to control the clamping feeding assembly to start.

[0050] The controller sends the clamping control information to the clamping and feeding assembly to control the clamping and feeding assembly to start.

[0051] After the pipe falls to the top of the lifting platform, the second pressure sensor generates second pressure information. After the lifting platform moves down to the bottom, the first pressure sensor generates first pressure information. The first pressure sensor sends the first pressure information to the controller, and the second pressure sensor sends the second pressure information to the controller. After receiving the first pressure information and the second pressure information at the same time, the controller generates clamping control information based on the first pressure information and the second pressure information. Then the controller sends the clamping control information to the clamping feeding assembly to start the clamping feeding assembly.

[0052] Preferably, it further includes:

[0053] The controller receives cutting completion information generated by the laser cutting frame after the cutting is completed;

[0054] The controller generates cleaning control information based on the cutting completion information, and the cleaning control information is used to control the cleaning component to start.

[0055] The controller sends the cleaning control information to the cleaning component to control the cleaning component to start;

[0056] After the laser cutting frame completes the cutting, it generates a cutting completion information and sends the cutting completion information to the controller. After receiving the cutting completion information, the controller generates cleaning control information based on the cutting completion information, and then sends the cleaning control information to the cleaning component to control the cleaning component to start.

[0057] Preferably, it further includes:

[0058] The controller receives cut completion information generated by the laser cutting frame after every two cuts are completed;

[0059] The controller generates material change control information based on the complete cutting information, and the material change control information is used to control the start of the conveying component.

[0060] The controller sends the material change control information to the conveying component to control the start of the conveying component;

[0061] After each two cuts, the laser cutting frame generates cut completion information. The laser cutting frame sends the cut completion information to the controller. After receiving the cut completion information, the controller generates material change control information based on the cut completion information. Subsequently, the controller sends the material change control information to the conveying component to control the start of the conveying component.

[0062] Compared with the prior art, the present invention has the following beneficial effects:

[0063] 1. The present invention, through the setting of the cleaning component, enables the cleaning component to clean the debris on the outer surface of the cut end of the pipe during the process of resetting the pipe into the recess. Furthermore, the setting of the cleaning component isolates the laser cutting position of the pipe from the recess position, thereby preventing the debris generated during the pipe cutting process from splashing into the recess position. This helps to avoid debris adhering to the recess and causing instability in the pipe clamping, thus helping to avoid laser cutting deviation caused by unstable pipe clamping.

[0077] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0078] like Figures 2 to 12 The laser cutting production apparatus for electric vehicle frame tubes shown includes a processing table 1, a laser cutting frame 101 installed inside the processing table 1, and further includes:

[0079] The housing 3 is fixed inside the processing table 1 by the support plate 2;

[0080] Rotating cylinder 5 is rotatably mounted on the top of housing 3 and driven by a rotation drive assembly. A notch 504 is provided inside the rotating cylinder 5.

[0081] The clamping and feeding assembly is installed inside the recess 504 and is used to clamp and transport the pipes entering the recess 504.

[0082] The conveying assembly, mounted on the rotating drum 5, is used for conveying pipe fittings into and out of the recess 504.

[0083] The cleaning component, installed on the side of the support plate 2, is used to clean debris from the surface of the laser-processed pipe and to reduce debris from entering the recess 504 by isolating it.

[0084] During the cutting process of electric vehicle frame tubes, the frame tubes need to be clamped and positioned before laser cutting. During the cutting process, the cut part of the tube will generate debris. If the debris falls into the clamping position of the tube, it will cause the clamping of the tube to shift, resulting in deviation of the laser cutting of the tube and thus affecting the processing efficiency of the tube.

[0085] This embodiment of the invention can solve the above problems. The specific implementation is as follows: the pipe is conveyed to the position of the notch 504 by the conveying assembly. After being conveyed above the notch 504, the pipe enters the interior of the notch 504. After the pipe enters the interior of the notch 504, the clamping and feeding assembly is activated to clamp the pipe. After clamping the pipe, the clamping and feeding assembly drives the pipe to feed towards the laser cutting frame 101, so that the end of the pipe extends into the position of the laser cutting frame 101. Then, after the laser cutting frame 101 is activated, it cuts the pipe. This allows for the cutting of one end of the pipe fitting. After the cutting of one end of the pipe fitting is completed, the cleaning component is activated. During the process of the pipe fitting resetting into the recess 504, the cleaning component cleans the debris on the outer surface of the cut end of the pipe fitting. Furthermore, the cleaning component is designed to isolate the laser cutting position of the pipe fitting from the position of the recess 504, thus preventing the debris generated during the pipe fitting cutting process from splashing into the recess 504. This helps to avoid debris adhering to the recess 504, causing instability in the pipe fitting clamping, and thus helps to avoid laser cutting deviation caused by unstable pipe fitting clamping.

[0086] After one end of the pipe is laser-cut, the clamping and feeding assembly is activated to convey and reset the pipe into the recess 504. Then, the rotation drive assembly drives the rotating cylinder 5 to rotate, thereby reversing the direction of both ends of the pipe. Afterward, the clamping and feeding assembly is activated again to convey the other end of the pipe into the position of the laser cutting frame 101, so that the laser cutting frame 101 can cut the other end of the pipe after it is activated. This achieves the cutting of both ends of the pipe. Furthermore, the setting of the conveying assembly eliminates the need for manual feeding of the pipe, which helps to improve the efficiency of laser cutting of the pipe.

[0087] As an optional embodiment, the rotation drive assembly includes:

[0088] The first gear 501 is fixed to the bottom of the rotating cylinder 5;

[0089] The first motor 503 is fixed inside the housing 3. The output shaft end of the first motor 503 is fixed with a second gear 502, which meshes with the first motor 503.

[0090] After the first motor 503 starts, it drives the second gear 502 to rotate through the output shaft. The rotation of the second gear 502 drives the first gear 501, which meshes with it, to rotate. The first gear 501 drives the rotating cylinder 5 to rotate, thereby driving the pipe to rotate and changing the position of the two ends through the rotation of the rotating cylinder 5.

[0091] As an optional embodiment, the delivery component includes:

[0092] The frame 4 is fixed to the inner wall of the processing table 1;

[0093] The feeding conveyor belt 9 is installed on one side inside the frame 4 via the first transmission drive assembly;

[0094] The unloading conveyor belt 10 is installed on the other side inside the frame 4 via the second transmission drive assembly. The feeding conveyor belt 9 and the unloading conveyor belt 10 are located on both sides of the notch 504, respectively.

[0095] The guide frame 1003 is fixed on the inner wall of the processing table 1 and is connected to the unloading conveyor belt 10.

[0096] A lifting drive assembly is installed inside the recess 504 to drive the pipe fitting to move up and down;

[0097] After the first conveying drive component is started, it drives the feeding conveyor belt 9 to drive, and the feeding conveyor belt 9 conveys the pipe to the notch 504 position. The feeding speed of the pipe is controlled by controlling the transmission frequency of the feeding conveyor belt 9. After the second conveying drive component is started, it drives the unloading conveyor belt 10 to drive, and the unloading conveyor belt 10 conveys the cut pipe to the unloading position. The unloaded pipe slides down and is collected by the guide frame 1003, thereby realizing automatic loading and unloading of pipes. The lifting drive component can convey the pipe that reaches the notch 504 position. When the lifting drive component conveys the pipe to the lowest position of the notch 504, the clamping feeding component can clamp the pipe. When the lifting drive component conveys the pipe to the highest position of the notch 504, the pipe can be pushed by the pipe on the feeding conveyor belt 9 into the unloading conveyor belt 10 for replacement.

[0098] As an optional embodiment, the first transmission drive component includes:

[0099] Two first rotating rollers 901 are rotatably installed inside the frame 4, and the feeding conveyor belt 9 is driven and sleeved on the outside of the two first rotating rollers 901;

[0100] The third motor 902 is fixed to the outer wall of the processing table 1. The third motor 902 drives one of the first rotating rollers 901 to rotate through the output shaft.

[0101] After the third motor 902 starts, it drives one of the first rotating rollers 901 to rotate through the output shaft. After the first rotating roller 901 rotates, it drives the feeding conveyor belt 9 to drive.

[0102] As an optional embodiment, the second transmission drive component includes:

[0103] Two second rotating rollers 1001 are rotatably installed inside the frame 4, and the feeding conveyor belt 10 is driven and sleeved on the outside of the two second rotating rollers 1001;

[0104] The fourth motor 1002 is fixed on the outer wall of the processing table 1. The fourth motor 1002 drives one of the second rotating rollers 1001 to rotate through the output shaft.

[0105] After the fourth motor 1002 starts, it drives one of the second rotating rollers 1001 to rotate through the output shaft. After the second rotating roller 1001 rotates, it drives the feeding conveyor belt 10 to drive.

[0106] As an optional embodiment, the lifting drive assembly includes:

[0107] The lifting platform 6 is vertically slidably installed inside the recess 504;

[0108] The first cylinder 601 is fixed inside the housing 3, and the end of the telescopic rod of the first cylinder 601 is rotatably connected to the bottom center of the lifting platform 6.

[0109] After the first cylinder 601 is started, it pushes the lifting platform 6 to move vertically through the telescopic rod. The end of the telescopic rod of the first cylinder 601 is rotatably connected to the lifting platform 6, so that the rotating cylinder 5 can maintain the connection with the end of the telescopic rod of the first cylinder 601 during the rotation of the lifting platform 6.

[0110] As an optional embodiment, the cleaning component includes:

[0111] The vertical plate 11 is fixed to the side of the support plate 2, and a round hole for pipe fittings to pass through is opened in the middle of the vertical plate 11.

[0112] The threaded drive disc 19 is rotatably mounted inside the circular hole and driven by the clamping drive assembly.

[0113] Multiple sliders 20 are arranged in a circular array and are slidably connected to the threaded groove of the threaded drive disk 19 through sliding contacts. The sliders 20 are slidably connected to the vertical plate 11 through the straight rod 2001. All sliders 20 are fixed with absorbent cotton 21 and rubber scraper block 22 on the side facing away from the threaded drive disk 19. The absorbent cotton 21 is located between the rubber scraper block 22 and the slider 20.

[0114] The nozzle holder 12 is fixed to the side wall of the vertical plate 11, and multiple nozzles 13 are linearly fixed at the bottom of the nozzle holder 12.

[0115] A water delivery assembly, installed below the vertical plate 11, is used to store and deliver water to the nozzle 13;

[0116] The pipe passes through the round hole in the middle of the vertical plate 11 to the position of the laser cutting frame 101 for cutting. After cutting, the clamping and feeding assembly drives the pipe to retreat into the recess 504. At this time, the water flow conveying assembly is activated, which conveys water to the nozzle 13, so that the water flow sprayed from the nozzle 13 forms a water curtain. When the pipe passes through the water curtain, the debris on the surface of the pipe is cleaned, which helps to prevent the debris attached to the surface of the pipe from entering the recess 504 and causing clamping interference, thus helping to avoid unstable clamping of the pipe. At the same time, the clamping drive assembly is activated to drive the thread drive disk 19 to rotate. After the thread drive disk 19 rotates, it drives the slider 20 through the thread track of the thread groove. The straight rod 2001 is slidably connected to the vertical plate 11, so that the vertical plate 11 can only slide on the trajectory of the straight rod 2001. This allows all the sliders 20 to come closer together to clamp the tube. The sliders 20 drive the absorbent cotton 21 and the rubber scraper block 22 to come closer together to clamp the surface of the tube. After the surface of the tube is clamped, the rubber scraper block 22 adheres to the surface of the tube, thereby scraping away water stains on the surface of the tube. When the tube reaches the position of the absorbent cotton 21, the absorbent cotton 21 can absorb the residual moisture on the surface of the tube. This helps to prevent water from flowing into the interior of the notch 504 with the tube and interfering with the clamping stability. This helps to prevent the accuracy of laser cutting from being interfered with due to the unstable clamping of the tube.

[0117] As an optional embodiment, the clamping drive component includes:

[0118] The fifth motor 1904 is fixed to the side of the vertical plate 11;

[0119] The third gear 1901 is rotatably mounted inside the mounting slot inside the vertical plate 11;

[0120] Turbine 1902 is coaxially and fixedly connected to the third gear 1901;

[0121] Worm 1903 is fixed to the end of the output shaft of the fifth motor 1904, and worm 1903 meshes with turbine 1902;

[0122] A fourth gear is mounted on the outside of the threaded drive disc 19, and the fourth gear meshes with the third gear 1901;

[0123] After the fifth motor 1904 starts, it drives the worm gear 1903 to rotate through the output shaft. The worm gear 1903 drives the worm 1902 that meshes with it to rotate. The worm 1902 drives the third gear 1901 to rotate. The third gear 1901 drives the fourth gear that meshes with it to rotate. In turn, the fourth gear drives the thread drive disk 19 to rotate, thereby driving the thread drive disk 19.

[0124] As an optional embodiment, the cleaning component further includes:

[0125] The filter frame 15 is fixed inside the processing table 1. A flip filter plate 18 is rotatably installed in the middle of the filter frame 15. A torsion spring is sleeved on the rotating shaft of the flip filter plate 18. The two ends of the torsion spring are fixedly connected to the flip filter plate 18 and the filter frame 15 respectively.

[0126] The U-shaped pusher 1905 is vertically slidably connected to the filter frame 15. When the U-shaped pusher 1905 moves vertically, it pushes the flip filter plate 18 to flip.

[0127] The screw 1906 is rotatably mounted below the vertical plate 11. The screw 1906 is threadedly connected to the U-shaped push frame 1905. The clamping drive assembly is also used to drive the screw 1906 to rotate.

[0128] The worm gear 1903 of the clamping drive assembly rotates, causing the screw 1906 to rotate. After the screw 1906 rotates, it drives the U-shaped pusher 1905, which is threaded to it, to move vertically. After the U-shaped pusher 1905 moves vertically, it pushes one end of the flip filter plate 18 upward, causing the flip filter plate 18 to flip. When the flip filter plate 18 flips, under the action of the water flow from the nozzle 13, the debris on the inclined surface of the flip filter plate 18 is flipped upward and cleaned. This helps to prevent debris from accumulating on the surface of the flip filter plate 18 and interfering with laser cutting. At the same time, the flip filter plate 18 can intercept and support falling debris, thereby preventing the water splashed from falling debris from interfering with laser cutting.

[0129] As an optional embodiment, the water delivery assembly includes:

[0130] Water tank 16 is fixed inside the processing table 1 and fixed to the bottom of the support plate 2;

[0137] The feed drive assembly is installed on both sides of the notch 504 to drive the pipe fitting to move;

[0138] After the electric telescopic rod 701 is started, it pushes the clamping block 7 to move through the end of the telescopic rod, so that the clamping block 7 extends into the interior of the notch 504 to clamp the pipe, which helps to prevent the pipe from becoming loose or shifting during the laser cutting process.

[0139] As an optional embodiment, the feed drive assembly includes:

[0140] Multiple movable frames 802 are divided into two groups and are linearly arrayed and slidably installed inside the rotating cylinder 5. The two groups of movable frames 802 are located on both sides of the recess 504.

[0143] After the second cylinder 807 is started, it pushes the moving frame 802 to move into the recess 504. The moving frame 802 drives the drive roller 8 to move through the opening 801 into the recess 504, thereby adjusting the clamping force between the drive roller 8 and the tube. The drive component drives the drive roller 8 to rotate. After the drive roller 8 clamps the tube to the required force, the rotation of the drive roller 8 drives the tube to move, thereby driving the tube to achieve laser cutting at both ends of the tube.

[0145] The second synchronous pulley 805 is fixedly connected to the drive roller 8 on the same axis.

[0146] The second motor 803 is fixed on the side wall of the movable frame 802. The output shaft of the second motor 803 is fixed with the first synchronous pulley 804. The first synchronous pulley 804 and the second synchronous pulley 805 are connected by a synchronous belt 806.

[0147] After the second motor 803 starts, it drives the first synchronous pulley 804 to rotate. The first synchronous pulley 804 drives the second synchronous pulley 805 to rotate through the synchronous belt 806. The second synchronous pulley 805 drives the drive roller 8 to rotate, thereby driving the drive roller 8.

[0148] like Figure 1 The control method of a laser cutting production device for electric vehicle frame tubes is shown. A controller is installed inside the processing table 1. A first pressure sensor is fixed to the top of the lifting platform 6, and a second pressure sensor is fixed to the bottom of the lifting platform 6. The control method includes the following steps:

[0149] The controller receives the first pressure information obtained by the first pressure sensor;

[0150] The controller receives the second pressure information acquired by the second pressure sensor;

[0151] When the controller receives both the first pressure information and the second pressure information, it generates clamping control information based on the first pressure information and the second pressure information. The clamping control information is used to control the start of the clamping and feeding assembly.

[0152] The controller sends clamping control information to the clamping and feeding assembly to control the clamping and feeding assembly to start;

[0153] After the pipe falls to the top of the lifting platform 6, the second pressure sensor generates second pressure information. After the lifting platform 6 moves down to the bottom, the first pressure sensor generates first pressure information. The first pressure sensor sends the first pressure information to the controller, and the second pressure sensor sends the second pressure information to the controller. After receiving the first pressure information and the second pressure information at the same time, the controller generates clamping control information based on the first pressure information and the second pressure information. Then the controller sends the clamping control information to the clamping feeding assembly to start the clamping feeding assembly.

[0154] As an optional embodiment, it also includes:

[0155] The controller receives cutting completion information generated by the laser cutting frame 101 after the cutting is completed;

[0156] The controller generates cleaning control information based on the cutting completion information, and the cleaning control information is used to control the start of the cleaning component.

[0157] The controller sends cleanup control information to the cleanup component to control the cleanup component to start;

[0158] After the laser cutting frame 101 completes the cutting, it generates cutting completion information and sends the cutting completion information to the controller. After receiving the cutting completion information, the controller generates cleaning control information based on the cutting completion information. Subsequently, the controller sends the cleaning control information to the cleaning component to control the cleaning component to start.

[0159] As an optional embodiment, it also includes:

[0160] The controller receives the cut completion information generated by the laser cutting frame 101 after every two cuts are completed;

[0161] The controller generates material change control information based on the complete cutting information, which is used to control the start of the conveyor assembly.

[0162] The controller sends material change control information to the conveying assembly to control the start of the conveying assembly;

[0163] After each two cuts are completed, the laser cutting frame 101 generates a cut completion information and sends it to the controller. After receiving the cut completion information, the controller generates material change control information based on the cut completion information. Subsequently, the controller sends the material change control information to the conveying component to control the start of the conveying component.

[0164] Working principle of this invention: The pipe is conveyed to the position of the notch 504 by the conveying assembly. After being conveyed above the notch 504, the pipe enters the interior of the notch 504. After the pipe enters the interior of the notch 504, the clamping and feeding assembly is activated to clamp the pipe. After clamping the pipe, the clamping and feeding assembly drives the pipe to feed towards the laser cutting frame 101, so that the end of the pipe extends into the position of the laser cutting frame 101. The laser cutting frame 101 is then activated to cut the pipe, thereby achieving one-time cutting of the pipe. After the cutting of one end of the pipe is completed, the cleaning component is activated. During the process of the pipe resetting into the recess 504, the cleaning component cleans the debris on the outer surface of the cut end of the pipe. Furthermore, the cleaning component is designed to isolate the laser cutting position of the pipe from the position of the recess 504, so that the debris generated during the pipe cutting process will not splash into the recess 504. This helps to avoid debris adhering to the recess 504 and causing instability in the pipe clamping, thus helping to avoid laser cutting deviation caused by unstable pipe clamping.

[0165] After one end of the pipe is laser-cut, the clamping and feeding assembly is activated to convey and reset the pipe into the recess 504. Then, the rotation drive assembly drives the rotating cylinder 5 to rotate, thereby reversing the direction of both ends of the pipe. Afterward, the clamping and feeding assembly is activated again to convey the other end of the pipe into the position of the laser cutting frame 101, so that the laser cutting frame 101 can cut the other end of the pipe after it is activated. This achieves the cutting of both ends of the pipe. Furthermore, the setting of the conveying assembly eliminates the need for manual feeding of the pipe, which helps to improve the efficiency of laser cutting of the pipe.
