Description

Technical Field

[0001] This invention relates to the field of intelligent laser processing equipment technology, and in particular to a laser cutting device and method. Background Technology

[0002] After welding, ultra-thin heat-sealable plates accumulate excess material around the weld. This excess material not only severely affects the surface smoothness and flatness of the heat-sealable plate but also interferes with subsequent processing accuracy and can even lead to assembly errors. In existing technologies, laser cutting equipment cannot accurately identify the boundary between the weld and the excess material, easily resulting in the cutting off of the weld or leaving residual excess material. Furthermore, laser cutting equipment struggles to handle situations with blurred weld edges and irregularly shaped excess material, generating cutting trajectories that deviate significantly from actual requirements, resulting in uneven, rough cuts with burrs. Summary of the Invention

[0003] This invention provides a laser cutting device and method that can improve cutting accuracy, protect weld integrity, accurately identify the boundary between weld and irregular excess material, and ensure that the cut is continuous, flat and burr-free.

[0004] In a first aspect, embodiments of the present invention provide a laser cutting device, including a machine body, a feeding conveyor line, a discharging conveyor line, a flipping structure, a feeding and handling structure, a discharging and handling structure, a vision positioning structure, a cutting structure, a waste collection structure, and a control structure.

[0005] The machine body is located between the feeding conveyor line and the unloading conveyor line. The feeding conveyor line is used to transport the material to be cut, and the unloading conveyor line is used to transport the material after laser cutting.

[0006] The flipping structure and the feeding conveyor line are located on the same side of the machine body. The flipping structure is used to adjust the orientation of the material to be cut and to convey the material to be cut after the orientation is adjusted to the feeding conveyor line.

[0007] The feeding and conveying structure is located at the output end of the feeding conveyor line. The feeding and conveying structure is used to grab the material to be cut from the feeding conveyor line. The unloading and conveying structure is located at the input end of the unloading conveyor line. The unloading and conveying structure is used to grab the laser-cut material inside the machine body to the unloading conveyor line.

[0008] The visual positioning structure is located inside the machine body. The visual positioning structure is used to identify the weld seam of the material to be cut and the outline of the excess material around the weld seam, and generate the corresponding cutting trajectory.

[0009] The cutting structure is located inside the machine body and is used to cut off excess material around the weld according to the cutting trajectory.

[0010] The waste collection structure is located below the cutting structure and is used to collect the waste generated during cutting.

[0011] The control structure is electrically connected to the feeding conveyor line, unloading conveyor line, flipping structure, feeding and handling structure, unloading and handling structure, vision positioning structure, cutting structure, and waste collection structure to coordinate the control of each structure to complete the automatic cutting of excess material in the material to be cut.

[0012] This invention provides a continuous production line for laser cutting equipment by incorporating a flipping structure, a feeding and unloading structure, a vision positioning structure, a cutting structure, a waste collection structure, and a control structure. The machine body is fixedly positioned between the feeding and unloading conveyor lines, forming a continuous operation line for feeding, cutting, and unloading. The flipping structure is installed on the same side as the feeding conveyor line and connects to it, ensuring that the flipped material can directly enter the feeding conveyor line. The feeding and unloading structure is located at the output end of the feeding conveyor line and is used to pick up the material to be cut from the feeding conveyor line. The unloading and unloading structure is located at the input end of the unloading conveyor line and is used to pick up the laser-cut material inside the machine body and transfer it to the unloading conveyor line, ensuring that the transfer path accurately covers the feeding conveyor line, the cutting station, and the unloading conveyor line. The visual positioning structure is used to identify the weld seam and the outline of excess material around the weld seam of the material to be cut, and generate a corresponding cutting trajectory. The cutting structure is used to cut the excess material around the weld seam according to the cutting trajectory, which helps to improve the cutting accuracy, protect the integrity of the weld seam, accurately identify the boundary between the weld seam and irregular excess material, and ensure that the cut is continuous, flat and burr-free.

[0013] This invention addresses this issue by placing a waste collection structure below the cutting structure to collect waste generated during cutting, preventing waste accumulation at the cutting station and avoiding its impact on subsequent cutting accuracy. By incorporating a control structure electrically connected to the feeding and unloading conveyor lines, the flipping structure, the feeding and unloading transport structure, the vision positioning structure, the cutting structure, and the waste collection structure, the laser cutting equipment integrates fully automated functions for flipping, feeding, positioning, cutting, waste handling, and unloading. The feeding and unloading transport structures operate synchronously, facilitating coordinated control throughout the entire process and improving batch cutting efficiency.

[0014] According to the aforementioned embodiment of the first aspect of the present invention, the flipping structure includes: a support frame, a first driving unit, a flipping bracket, and a rotating shaft. The first driving unit is electrically connected to a control structure, which controls the first driving unit to start or stop working. The flipping bracket is disposed in the middle of the support frame and includes two opposing abutment portions forming a locking position between them, which is used to hold the material to be cut. The rotating shaft is disposed in the middle of the support frame and is driven between the first driving unit and the flipping bracket, and is connected to the abutment portions. The first driving unit drives the rotating shaft to rotate, thereby driving the flipping bracket to rotate 180° around its own axis, so that the material to be cut flips so that the cutting surface faces upward. The technical solution of the present invention improves the stability of the flipping bracket by disposing the flipping bracket and the rotating shaft of the flipping structure in the middle of the support frame, and avoids tilting of the flipping structure due to uneven force during flipping.

[0015] According to the foregoing embodiments of the first aspect of the present invention, both the loading and unloading conveying structures include a second driving unit, a connecting rod, multiple vacuum adsorption components, and a lifting assembly. The connecting rod is drively connected to the second driving unit. Multiple vacuum adsorption components are arranged sequentially and evenly at intervals on the connecting rod, adsorbing the material to be cut. The lifting assembly can drive the connecting rod to move along the Z-axis, thereby driving the vacuum adsorption components to move along the Z-axis. The technical solution of the present invention, by setting up vacuum adsorption components, ensures uniform force on the material during the gripping process, avoids damage to the material during gripping, and prevents material deformation or detachment.

[0016] According to the foregoing embodiments of the first aspect of the present invention, the control structure can independently control the suction force and on / off state of each vacuum adsorption element. The technical solution of the present invention, by setting a control structure that can independently control the suction force and on / off state of each vacuum adsorption element, can automatically and individually adjust each vacuum adsorption element according to materials of different sizes and flatnesses. This allows the loading and unloading transport structures to adsorb various materials of different shapes, sizes, and flatnesses, expanding the scope of application of the equipment and improving its compatibility.

[0017] According to the aforementioned embodiment of the first aspect of the present invention, the cutting structure includes: a base, an X-axis servo module, a Y-axis servo module, a Z-axis servo module, and a laser cutting head. The base is used to place the material to be cut. The X-axis servo module, the Y-axis servo module, and the Z-axis servo module are all disposed on the base. The laser cutting head is drivenly connected to the X-axis servo module, the Y-axis servo module, and the Z-axis servo module, and the X-axis servo module, the Y-axis servo module, and the Z-axis servo module are linked together to jointly drive the laser cutting head to move along the X-axis, Y-axis, and Z-axis, so that the laser cutting head cuts the excess material around the weld of the material to be cut according to the cutting trajectory generated by the vision positioning structure.

[0018] According to the aforementioned embodiments of the first aspect of the present invention, the cutting structure further includes a laser parameter adjustment component. The laser parameter adjustment component is electrically connected to the control structure and the laser cutting head. The laser parameter adjustment component is used to set and adjust the corresponding laser output power, laser wavelength, and spot size of the laser cutting head according to different materials to be cut. By setting the laser parameter adjustment component, the technical solution of the present invention can set and adjust the corresponding laser output power, laser wavelength, and spot size of the laser cutting head according to different materials to be cut. Adjusting these parameters helps to improve the smoothness of the cut surface and reduce the heat-affected zone and deformation of the material to be cut during the cutting process, thus adapting to different production needs.

[0019] According to the foregoing embodiment of the first aspect of the present invention, the visual positioning structure includes a visual positioning camera disposed above a base along the Z-axis direction. The visual positioning structure also includes a supplementary lighting component and a deep learning processing module. The visual positioning camera cooperates with the supplementary lighting component to acquire images of the weld seam of the material to be cut and the excess material around the weld seam. The deep learning processing module analyzes and learns from the images to identify the weld seam position and the outline of the excess material around the weld seam, thereby generating a cutting trajectory adapted to different weld seam shapes. The control structure can control the X-axis servo module, Y-axis servo module, and Z-axis servo module to work together to drive the laser cutting head to complete the cutting of the excess material according to the cutting trajectory. The technical solution of this invention utilizes a visual positioning camera, a supplementary lighting component, and a deep learning processing module. The visual positioning camera and the supplementary lighting component work together to acquire images of the weld seam and surrounding excess material of the material to be cut. The deep learning processing module analyzes and learns from the images to identify the location of the weld seam and the outline of the excess material around the weld seam, thereby generating a cutting trajectory adapted to different weld seam shapes. The control structure can control the X-axis servo module, Y-axis servo module, and Z-axis servo module to work together to drive the laser cutting head to complete the cutting of excess material. This facilitates the intelligent identification of excess material from weld seams of different shapes, accurately identifies the boundary between the weld seam and irregular excess material, optimizes the cutting trajectory, improves the accuracy and efficiency of cutting excess material from the weld seam, protects the integrity of the weld seam, and ensures a continuous, smooth, and burr-free cut.

[0020] According to the aforementioned embodiment of the first aspect of the present invention, the cutting structure further includes a cleaning assembly and a dust collection hood. The cleaning assembly is disposed on one side of the laser cutting head and electrically connected to a control structure. The control structure can control the cleaning assembly to move along the X-axis, Y-axis, and Z-axis to sweep the waste generated after cutting into a waste collection structure. The dust collection hood is disposed on one side of the laser cutting head and is used to collect the dust generated during the cutting process. The technical solution of the present invention, by setting up a cleaning assembly and a dust collection hood, helps to avoid waste accumulation at the cutting station and prevents waste accumulation from affecting subsequent cutting accuracy.

[0021] According to the aforementioned embodiment of the first aspect of the present invention, the waste collection structure includes: a support plate, a third driving unit, and a waste trough. The support plate is disposed below the base and is used to support the waste generated after cutting. The third driving unit is drively connected to the support plate and can drive the support plate to rotate horizontally. The waste trough is disposed below the support plate, and the horizontal rotation of the support plate pours the supported waste into the waste trough. The technical solution of the present invention, by setting the support plate below the base to support the waste generated after cutting, and by having the third driving unit drive the support plate to rotate horizontally to pour the supported waste into the waste trough, helps to avoid waste accumulation at the cutting station and prevents waste accumulation from affecting subsequent cutting accuracy.

[0022] According to any of the foregoing embodiments of the first aspect of the present invention, both the feeding conveyor and the unloading conveyor include a speed-regulating motor and a position sensor, which are electrically connected to the control structure. The speed-regulating motor is driven by the feeding and unloading conveyors and is used to adjust the conveying speed of the feeding and unloading conveyors. The position sensor is located at the output end of the feeding and unloading conveyors. When the position sensor detects that the material to be cut in the feeding conveyor has reached the feeding position of the cutting structure, or that the cut material in the unloading conveyor has reached the next process, the control structure controls the feeding and unloading conveyors to stop conveying. The technical solution of the present invention, by setting a speed-regulating motor and a position sensor, can flexibly adjust the speed of the feeding and unloading conveyors to adapt to different production needs. By setting the position sensor, when the position sensor detects that the material to be cut in the feeding conveyor has reached the feeding position of the cutting structure, or that the cut material in the unloading conveyor has reached the next process, the control structure controls the feeding and unloading conveyors to stop conveying, which is beneficial to improving the automation level of the cutting process.

[0023] According to any of the foregoing embodiments of the first aspect of the present invention, the distance between the cut formed by the cutting structure and the weld of the material to be cut is not less than 1m. The technical solution of the present invention effectively avoids cutting off the weld by setting the distance between the cut formed by the cutting structure and the weld of the material to be cut to not less than 1m.

[0024] According to any of the foregoing embodiments of the first aspect of the present invention, the control structure includes: a touch screen, a display, control buttons, and an operating component. The touch screen is disposed outside the machine body and is used to input the operating parameters and operating instructions of each structure. The display is disposed outside the machine body and is used to display the operating status of each structure and the generated cutting trajectory. The control buttons are disposed outside the machine body and are used to control the emergency start / stop and operating mode switching of the laser cutting equipment. The operating component is used for image recognition training of the visual positioning structure.

[0025] In a second aspect, embodiments of the present invention provide a laser cutting method, which uses a laser cutting device according to any of the foregoing embodiments of the first aspect of the present invention to cut excess material around the weld seam of a heat-sealing plate. The laser cutting method includes:

[0026] The orientation of the heat-sealing plate is adjusted by the flipping structure. The flipping structure flips the heat-sealing plate 180° so that the convex side of the heat-sealing plate faces upward, resulting in the heat-sealing plate to be cut.

[0027] The heat-sealed plate to be cut is conveyed to the feeding conveyor line, and the feeding and handling structure picks up the heat-sealed plate to be cut from the feeding conveyor line and moves it to the cutting station of the cutting structure.

[0028] The visual positioning structure identifies the weld seam and the outline of excess material around the weld seam of the heat-sealed plate to be cut, and generates a cutting trajectory.

[0029] Based on the cutting trajectory, excess material around the weld is trimmed through the cutting structure;

[0030] After cutting, the waste material is discharged into the waste collection structure;

[0031] The cutting heat-sealed plate is picked up from the cutting station of the cutting structure and transferred to the unloading conveyor line, which then outputs the cut heat-sealed plate to the next process.

[0032] The laser cutting method of this invention uses a laser cutting device to cut excess material around the weld of a heat-sealing plate. A flipping structure adjusts the orientation of the heat-sealing plate, rotating it 180° so that the convex side faces upwards, resulting in the heat-sealing plate to be cut. A feeding and conveying structure picks up the heat-sealing plate from the feeding conveyor line and moves it to the cutting station of the cutting structure. A visual positioning structure identifies the weld and the outline of the excess material around the weld on the heat-sealing plate to be cut, generating a cutting trajectory. Based on the cutting trajectory, the weld is cut using the cutting structure. Excess material is collected in a waste collection structure after cutting. The cut heat-sealed plate is then picked up from the cutting station of the cutting structure and transferred to the unloading conveyor line via the unloading transport structure. The unloading conveyor line then outputs the cut heat-sealed plate to the next process. By incorporating a flipping structure, a loading and unloading transport structure, a vision positioning structure, a cutting structure, a waste collection structure, and a control structure within the laser cutting equipment, and with the machine body fixedly positioned between the loading and unloading conveyors, a continuous loading-cutting-unloading production line is formed. The flipping structure is installed on the same side as the loading conveyor line and connects with it, ensuring that the flipped material can directly enter the loading conveyor line. The loading and handling structure is located at the output end of the loading conveyor line. This structure picks up the material to be cut from the loading conveyor line. The unloading and handling structure is located at the input end of the unloading conveyor line. This structure picks up the laser-cut material from inside the machine and transfers it to the unloading conveyor line, ensuring a precise transport path covering the loading conveyor line, cutting station, and unloading conveyor line. The visual positioning structure identifies the weld seam and the outline of excess material around the weld seam, generating a corresponding cutting trajectory. The cutting structure cuts the excess material around the weld seam according to this trajectory, improving cutting accuracy, protecting weld integrity, accurately identifying the boundary between the weld seam and irregular excess material, and ensuring a continuous, smooth, and burr-free cut.

[0033] This invention addresses this issue by placing a waste collection structure below the cutting structure to collect waste generated during cutting, preventing waste accumulation at the cutting station and avoiding its impact on subsequent cutting accuracy. By incorporating a control structure electrically connected to the feeding and unloading conveyor lines, the flipping structure, the feeding and unloading transport structure, the vision positioning structure, the cutting structure, and the waste collection structure, the laser cutting equipment integrates fully automated functions for flipping, feeding, positioning, cutting, waste handling, and unloading. The feeding and unloading transport structures operate synchronously, facilitating coordinated control throughout the entire process and improving batch cutting efficiency.

[0047] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0048] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0050] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0051] This invention relates to the field of intelligent laser processing equipment technology, and provides a laser cutting device and method that can improve cutting accuracy, protect weld integrity, accurately identify the boundary between weld and irregular excess material, and ensure that the cut is continuous, flat and burr-free.

[0052] like Figure 1 As shown, this embodiment of the invention provides a laser cutting device, including a machine body 100, a feeding conveyor line 200, a discharging conveyor line 300, a flipping structure 400, a feeding and handling structure 500a, a discharging and handling structure 500b, a vision positioning structure (not shown in the figure), a cutting structure 700, a waste collection structure 800, and a control structure 900.

[0053] like Figure 1 As shown, the machine body 100 is positioned between the feeding conveyor line 200 and the unloading conveyor line 300. The feeding conveyor line 200 is used to transport the material 1000 to be cut, and the unloading conveyor line 300 is used to transport the material 1000 after laser cutting. In some embodiments, a safety net 210 is provided around the flipping structure 400 and the feeding conveyor line 200 to isolate the equipment operating area and ensure operational safety. The unloading conveyor line 300 is covered with a protective cover 310 to prevent external impurities from contaminating the surface of the material 1000 and to protect the cut material 1000.

[0054] like Figure 1 As shown, the flipping structure 400 and the feeding conveyor line 200 are located on the same side of the machine body 100. The flipping structure 400 is used to adjust the orientation of the material to be cut 1000 and to convey the material to be cut 1000 after the orientation is adjusted to the feeding conveyor line 200.

[0055] like Figure 1 As shown, the feeding and conveying structure 500a is located at the output end of the feeding conveyor line 200. The feeding and conveying structure 500a is used to pick up the material 1000 to be cut from the feeding conveyor line 200. The unloading and conveying structure 500b is located at the input end of the unloading conveyor line 300. The unloading and conveying structure 500b is used to pick up the laser-cut material 1000 from inside the machine body 100 and transfer it to the unloading conveyor line 300. It can be understood that the feeding and conveying structures 500a and 500b are connected in parallel and can work synchronously.

[0056] like Figure 1 As shown, the visual positioning structure is set inside the machine body 100. The visual positioning structure is used to identify the weld seam and the outline of excess material around the weld seam of the material to be cut 1000, and generate the corresponding cutting trajectory.

[0057] like Figure 1 As shown, the cutting structure 700 is located inside the machine body 100. The cutting structure 700 is used to cut excess material around the weld according to the cutting trajectory.

[0058] like Figure 1 As shown, the waste collection structure 800 is located below the cutting structure 700 and is used to collect waste generated during cutting.

[0059] like Figure 1 As shown, the control structure 900 is electrically connected to the feeding conveyor line 200, the unloading conveyor line 300, the flipping structure 400, the feeding and handling structure 500a, the unloading and handling structure 500b, the vision positioning structure, the cutting structure 700, and the waste collection structure 800, so as to coordinate the control of each structure to complete the automatic cutting of excess material in the material to be cut 1000.

[0060] The technical solution of this invention involves incorporating a flipping structure 400, a feeding and conveying structure 500a, a discharging and conveying structure 500b, a vision positioning structure, a cutting structure 700, a waste collection structure 800, and a control structure 900 into a laser cutting equipment. The machine body 100 is fixedly positioned between the feeding conveyor line 200 and the discharging conveyor line 300, forming a continuous production line for feeding, cutting, and discharging. The flipping structure 400 is installed on the same side as the feeding conveyor line 200 and connects with it, ensuring that the flipped material 1000 can directly enter the feeding conveyor line 200. The feeding and conveying structure 500a is located at the output end of the feeding conveyor line 200, and the discharging and conveying structure 500b is located at the input end of the discharging conveyor line 300, ensuring that the transfer path accurately covers the feeding conveyor line 200, the cutting station, and the discharging conveyor line 300. The visual positioning structure is used to identify the weld seam and the outline of the excess material around the weld seam of the material to be cut 1000, and generate a corresponding cutting trajectory. The cutting structure 700 is used to cut the excess material around the weld seam according to the cutting trajectory, which helps to improve the cutting accuracy, protect the integrity of the weld seam, accurately identify the boundary between the weld seam and the irregular excess material, and ensure that the cut is continuous, flat and burr-free.

[0061] The technical solution of this invention involves placing a waste collection structure 800 below the cutting structure 700 to collect waste generated during cutting, preventing waste from accumulating at the cutting station and affecting subsequent cutting accuracy. By setting up a control structure 900, which is electrically connected to the feeding conveyor line 200, the unloading conveyor line 300, the flipping structure 400, the feeding and handling structure 500a, the unloading and handling structure 500b, the vision positioning structure, the cutting structure 700, and the waste collection structure 800, the laser cutting equipment integrates fully automated functions for flipping, feeding, positioning, cutting, waste handling, and unloading. The feeding and handling structures 500a and 500b work synchronously, facilitating full-process collaborative control and improving batch cutting efficiency.

[0062] The technical solution of this invention adopts an assembly line design, which can be connected with the product production line to realize fully automated product loading and unloading production, thereby improving the automation level of product production.

[0063] like Figure 2As shown, the flipping structure 400 includes: a support frame 410, a first drive unit 420, a flipping bracket 430, and a rotating shaft 440. The first drive unit is electrically connected to a control structure 900, which controls the first drive unit to start or stop working. The flipping bracket 430 is disposed in the middle of the support frame 410 and includes two opposing abutment portions 431, forming a locking position 432 between them. The locking position 432 is used to hold the material 1000 to be cut. The rotating shaft 440 is disposed in the middle of the support frame 410 and is driven between the first drive unit and the flipping bracket 430. The rotating shaft 440 is connected to the abutment portions 431. The first drive unit drives the rotating shaft 440 to rotate, thereby causing the flipping bracket 430 to rotate 180° around its own axis, so that the material 1000 to be cut flips to the side facing upwards.

[0064] It is understandable that the process preceding the flipping structure 400 also includes a conveying component, which is used to convey the material to be cut 1000 to the rotary clamp 432. The output end of the conveying component is connected to the input end of the feeding conveyor line 200, and is used to convey the flipped material 1000 to the position that can be adsorbed by the feeding and handling structure 500a.

[0065] like Figure 2 As shown, since the convex surface (including the weld side) of material 1000 faces downwards upon arrival, this is not conducive to subsequent visual positioning and laser cutting. Therefore, by setting a flipping structure 400, material 1000 is flipped 180° so that the convex surface (including the weld side) faces upwards, which is beneficial for subsequent visual positioning and laser cutting. The technical solution of this invention improves the stability of the flipping support 430 and the rotating shaft 440 of the flipping structure 400 by setting them in the middle of the support frame 410, thus preventing the flipping structure 400 from tilting due to uneven force during flipping.

[0066] like Figures 3 to 4 As shown, the loading and conveying structure 500a includes a second drive unit 510, a connecting rod 520, multiple vacuum adsorption components 530, and a lifting assembly 540. The connecting rod 520 is drive-connected to the second drive unit 510. The multiple vacuum adsorption components 530 are arranged evenly at intervals on the connecting rod 520, and the material 1000 to be cut is adsorbed by the vacuum adsorption components 530. Preferably, the vacuum adsorption component 530 is a vacuum suction cup. The unloading and conveying structure 500b has the same structure as the loading and conveying structure 500a, and will not be described again here.

[0067] like Figures 3 to 4As shown, the connecting rod 520 is slidably connected to the lifting assembly 540. The lifting assembly 540 can drive the connecting rod 520 to move along the Z-axis, thereby driving the vacuum adsorption component 530 to move along the Z-axis. The technical solution of this invention, by setting the vacuum adsorption component 530, ensures that the material 1000 is subjected to uniform force during the gripping process, avoiding damage to the material 1000 during gripping, and preventing the material 1000 from deforming or falling off. Specifically, the lifting assembly 540 includes a Z-axis lifting assembly 540.

[0068] Specifically, the second drive unit 510 includes a servo motor, and a rack and pinion transport module 1100 is installed on the linear conveying track of the loading conveyor line 200 and the unloading conveyor line 300. The rack and pinion transport module 1100 is arranged along the extension direction of the linear conveying track. The rack and pinion transport module 1100 has high transmission precision and can drive the loading transport structure 500a and the unloading transport structure 500b to accurately stop the material at the designated position, ensuring the positional accuracy of the material 1000 transfer. The rack and pinion has a strong load-bearing capacity and can carry a certain weight of material 1000 to complete the transport, adapting to the transfer needs of various workpieces and materials in the production line. Both the loading and unloading conveying structure 500a and the unloading conveying structure 500b are connected to the gear and rack conveying module 1100. The gear and rack conveying module 1100 can drive the loading and unloading conveying structure 500a to move along the loading conveyor line 200 and the unloading conveying structure 500b to move along the unloading conveyor line 300 (that is, move along the X-axis), which is conducive to realizing the automated transfer of materials 1000.

[0069] Specifically, such as Figure 4 As shown, the loading and conveying structure 500a in this application includes three connecting rods 520 and nine suction cups. Each connecting rod 520 is evenly equipped with three suction cups. The distance between the three connecting rods 520 can be adjusted by a slide rail. The suction cups can move along the X-axis, Y-axis, and Z-axis via the slide rail and the lifting assembly 540. The unloading and conveying structure 500b has the same structure as the loading and conveying structure 500a, and will not be described in detail here.

[0070] In some embodiments, the feeding conveyor line 200 also includes an NG box, and the feeding and handling structure 500a transports non-compliant materials 1000 to the NG box, which is used to store materials 1000 that have been determined to be non-compliant by inspection.

[0071] Preferably, the control structure 900 can independently control the suction force and on / off state of each vacuum adsorption element 530. By setting the control structure 900 to independently control the suction force and on / off state of each vacuum adsorption element 530, the present invention can automatically and individually adjust each vacuum adsorption element 530 according to materials 1000 of different sizes and flatnesses. This allows the loading and unloading conveying structures 500a and 500b to adsorb various materials of different shapes, sizes, and flatnesses, expanding the scope of application and improving the compatibility of the equipment.

[0072] like Figure 4 As shown, the loading and conveying structure 500a also includes multiple support columns 550, which are fixedly connected to the connecting rod 520 to enhance the structural stability of the vacuum adsorption component 530 and ensure uniform force on the product during adsorption.

[0073] like Figure 4 As shown, the loading and conveying structure 500a also includes multiple guide posts 560. The guide posts 560 provide guidance for the movement of the connecting rod 520 along the Z-axis, enhancing the stability of the connecting rod 520's movement. The unloading and conveying structure 500b has the same structure as the loading and conveying structure 500a, and will not be described in detail here.

[0074] like Figure 5 As shown, the cutting structure 700 includes: a base 710, an X-axis servo module 720, a Y-axis servo module 730, a Z-axis servo module 740, and a laser cutting head 750.

[0075] Specifically, the base 710 is used to place the material 1000 to be cut. In this application, the base 710 is the cutting station. Preferably, the base 710 is made of marble, which effectively reduces vibration interference generated during the cutting process and helps to extend the service life of the laser cutting equipment.

[0076] like Figure 5 As shown, the X-axis servo module 720, Y-axis servo module 730, and Z-axis servo module 740 are all mounted on the base 710. The laser cutting head 750 is connected to the X-axis servo module 720, Y-axis servo module 730, and Z-axis servo module 740. The X-axis servo module 720, Y-axis servo module 730, and Z-axis servo module 740 are linked together to drive the laser cutting head 750 to move along the X-axis, Y-axis, and Z-axis, so that the laser cutting head 750 cuts the excess material around the weld seam of the material to be cut 1000 according to the cutting trajectory generated by the vision positioning structure.

[0077] Specifically, the Y-axis servo module 730 includes a first Y-axis servo module and a second Y-axis servo module disposed on opposite sides of the base 710 and parallel to each other, forming a dual-drive gantry motion structure. The opposite ends of the X-axis servo module 720 are respectively mounted on the first Y-axis servo module and the second Y-axis servo module. The X-axis servo module 720 can move along the Y-axis under the drive of the first Y-axis servo module and the second Y-axis servo module. The Z-axis servo module 740 is disposed on the X-axis servo module 720, and the X-axis servo module 720 can move along the Z-axis under the drive of the Z-axis servo module 740, which helps improve the stability of the laser cutting head 750 during movement. The laser cutting head 750 is mounted on the X-axis servo module 720, and the X-axis servo module 720, Y-axis servo module 730, and Z-axis servo module 740 are linked to jointly drive the laser cutting head 750 to move along the X-axis, Y-axis, and Z-axis to adjust the cutting height.

[0078] Preferably, the cutting structure 700 further includes a laser generator 780 and a laser parameter adjustment component. The laser generator 780, the laser parameter adjustment component, and the control structure 900 and the laser cutting head 750 are electrically connected. The laser parameter adjustment component is used to set and adjust the laser output power of the laser generator 780 according to different materials to be cut 1000, thereby adjusting the laser wavelength and spot size of the laser cutting head 750.

[0079] The technical solution of this invention sets up a laser parameter adjustment component, which can set and adjust the corresponding laser output power, laser wavelength and spot size of the laser cutting head 750 according to different materials to be cut 1000. By adjusting the above parameters, it is beneficial to improve the flatness and smoothness of the cutting cut, and reduce the heat-affected zone and the deformation of the material to be cut 1000 during the cutting process, so as to adapt to different production needs.

[0080] like Figure 5 As shown, the visual positioning structure includes a visual positioning camera 600 (such as a CCD camera) positioned above the base 710 along the Z-axis direction to ensure clear and unobstructed image acquisition.

[0081] Preferably, the visual positioning structure further includes a supplementary lighting component and a deep learning processing module. The visual positioning camera 600 works in conjunction with the supplementary lighting component to acquire images of the weld seam and excess material around the weld seam of the material to be cut 1000. In some embodiments, the supplementary lighting component includes a ring-shaped LED supplementary light, which is fitted around the outside of the visual positioning camera 600 to provide a uniform light source and avoid shadow interference.

[0082] The deep learning processing module can be integrated into the main control board of the control structure 900. Through a preset weld seam recognition algorithm, the deep learning processing module analyzes and learns the surface images of the material 1000 captured by the visual positioning camera 600 to accurately identify the weld seam position and the outline of excess material around the weld seam of the material 1000 to be cut, thereby generating a cutting trajectory adapted to different weld seam shapes. The control structure 900 can control the X-axis servo module 720, Y-axis servo module 730, and Z-axis servo module 740 to work together to drive the laser cutting head 750 to complete the cutting of excess material according to the cutting trajectory.

[0083] The technical solution of this invention uses a visual positioning camera 600, a supplementary lighting component, and a deep learning processing module. The visual positioning camera 600 works in conjunction with the supplementary lighting component to acquire images of the weld seam and surrounding excess material of the material to be cut 1000. The deep learning processing module analyzes and learns from the images to identify the position of the weld seam and the outline of the excess material around the weld seam, thereby generating a cutting trajectory adapted to different weld seam shapes. The control structure 900 can control the X-axis servo module 720, Y-axis servo module 730, and Z-axis servo module 740 to work together to drive the laser cutting head 750 to complete the cutting of excess material. This facilitates the intelligent identification of excess material from weld seams of different shapes, accurately identifies the boundary between the weld seam and irregular excess material, optimizes the cutting trajectory, improves the accuracy and efficiency of cutting excess material from the weld seam, protects the integrity of the weld seam, and ensures a continuous, smooth, and burr-free cut.

[0084] like Figure 6 As shown, the cutting structure 700 also includes a cleaning component 760 and a dust extraction hood 770. The cleaning component 760 is disposed on one side of the laser cutting head 750 and electrically connected to the control structure 900. The control structure 900 can control the cleaning component 760 to move along the X, Y, and Z axes to sweep the waste generated after cutting into the waste collection structure 800. The dust extraction hood 770 is disposed on one side of the laser cutting head 750 and is used to collect and adsorb the dust generated during the cutting process. The technical solution of this invention, by setting up the cleaning component 760 and the dust extraction hood 770, helps to avoid waste accumulation at the cutting station and prevents waste accumulation from affecting subsequent cutting accuracy.

[0085] In some embodiments, the cleaning assembly 760 includes a cleaning brush 761 and a drive cylinder 762, which drives the cleaning brush 761 to extend and retract. A control structure 900 is electrically connected to the drive cylinder 762 and is capable of controlling the drive cylinder 762 to drive the cleaning brush 761 to extend and conform to the surface of the base 710, so as to sweep the waste generated from cutting into the waste trough.

[0086] like Figure 7As shown, the waste collection structure 800 includes: a support plate 810, a third drive unit 820, and a waste trough (not shown in the figure). The support plate 810 is disposed below the base 710 and is used to hold the waste generated after cutting. Preferably, the support plate 810 is a honeycomb panel. The third drive unit 820 is connected to the support plate 810 and can drive the support plate 810 to rotate horizontally. The waste trough is disposed below the support plate 810, and the support plate 810 rotates horizontally to pour the waste into the waste trough. The waste trough is connected to the waste outlet at the bottom of the machine body 100. In some embodiments, the waste trough is detachably disposed inside the machine body 100 for easy waste removal.

[0087] The technical solution of the present invention sets a support plate 810 below the base 710 to support the waste generated after cutting. The support plate 810 supports the waste generated after cutting, and the third driving unit 820 can drive the support plate 810 to rotate horizontally. The horizontal rotation of the support plate 810 can pour the supported waste into the waste tank, which helps to avoid the accumulation of waste at the cutting station and avoid the accumulation of waste affecting the subsequent cutting accuracy.

[0088] After cutting, the support plate 810 flips over to pour the waste into the waste trough, while the cleaning brush 761 extends and retracts to clean up any remaining waste, achieving thorough waste removal. After waste processing is complete, both the support plate 810 and the cleaning brush 761 return to their original positions.

[0089] Preferably, both the feeding conveyor 200 and the unloading conveyor 300 include a speed-regulating motor and a position sensor, which are electrically connected to the control structure 900. The speed-regulating motor is driven by the feeding conveyor 200 and the unloading conveyor 300, and the conveying speed of the feeding conveyor 200 and the unloading conveyor 300 can be manually adjusted when needed. The position sensor is located at the output end of the feeding conveyor 200 and the unloading conveyor 300. When the position sensor detects that the material to be cut 1000 in the feeding conveyor 200 has reached the feeding position of the cutting structure 700, or that the cut material 1000 in the unloading conveyor 300 has reached the next process, the control structure 900 controls the feeding conveyor 200 and the unloading conveyor 300 to stop conveying.

[0090] The technical solution of this invention, by setting up a speed-regulating motor and a position sensor, can flexibly adjust the speed of the feeding conveyor line 200 and the unloading conveyor line 300 to adapt to different production needs. By setting up the position sensor, when the position sensor detects that the material to be cut 1000 in the feeding conveyor line 200 has reached the feeding position of the cutting structure 700, or that the cut material 1000 in the unloading conveyor line 300 has reached the next process, the control structure 900 controls the feeding conveyor line 200 and the unloading conveyor line 300 to stop conveying, which helps to improve the automation level of the cutting process.

[0091] Preferably, the distance between the cut formed by the cutting structure 700 and the weld of the material to be cut 1000 is not less than 1m. This invention effectively avoids cutting off the weld by setting the distance between the cut formed by the cutting structure 700 and the weld of the material to be cut 1000 to be not less than 1m.

[0092] like Figure 1 As shown, the control structure 900 includes: a touch screen 910, a display 920, control buttons 930, and an operation component 940. The touch screen 910 is located outside the machine body 100 and is used to input the operating parameters and operation commands of each structure, such as cutting speed, suction cup force, and trajectory spacing. The display 920 is located outside the machine body 100 and is used to display the operating status of each structure and the generated cutting trajectory. The control buttons 930 are located outside the machine body 100 and include an emergency start / stop button and an operating mode switching button. The emergency start / stop button is used to control the emergency start / stop of the laser cutting equipment, and the operating mode switching button is used to switch operating modes to ensure operational safety. The operation component 940 includes a mouse and a keyboard, used for image recognition training and algorithm optimization of the visual positioning structure.

[0093] It is understood that the above are only some preferred embodiments of the control structure 900. This application does not limit the specific form of the control structure 900. Those skilled in the art can set the form of the control structure 900 according to actual needs in order to better control the various structures in the laser cutting equipment.

[0094] like Figure 8 As shown, this embodiment of the invention also provides a laser cutting method, which uses the laser cutting equipment of any of the foregoing embodiments of the invention to cut off excess material around the weld of a heat-sealing plate. The laser cutting method includes steps S100 to S600. This application can be applied to the laser cutting of ultra-thin heat-sealing plates.

[0095] like Figure 1As shown, this embodiment of the invention provides a laser cutting device, including a machine body 100, a feeding conveyor line 200, a discharging conveyor line 300, a flipping structure 400, a feeding and handling structure 500a, a discharging and handling structure 500b, a vision positioning structure, a cutting structure 700, a waste collection structure 800, and a control structure 900. The machine body 100 is disposed between the feeding conveyor line 200 and the discharging conveyor line 300. The feeding conveyor line 200 is used to transport the material to be cut 1000, and the discharging conveyor line 300 is used to transport the laser-cut material 1000. The flipping structure 400 is disposed on the same side of the machine body 100. The flipping structure 400 is used to adjust the orientation of the material to be cut 1000 and transport the adjusted material to be cut 1000 to the feeding conveyor line 200. The feeding and conveying structure 500a is located at the output end of the feeding conveyor line 200. It is used to pick up the material 1000 to be cut from the feeding conveyor line 200. The unloading and conveying structure 500b is located at the input end of the unloading conveyor line 300. It is used to pick up the laser-cut material 1000 inside the machine body 100 and transfer it to the unloading conveyor line 300. It can be understood that the feeding and conveying structures 500a and 500b are connected in parallel and can work synchronously. The vision positioning structure is located inside the machine body 100. It is used to identify the weld seam and the outline of excess material around the weld seam of the material 1000 to be cut and generate a corresponding cutting trajectory. The cutting structure 700 is located inside the machine body 100. It is used to cut the excess material around the weld seam according to the cutting trajectory. The waste collection structure 800 is located below the cutting structure 700. It is used to collect the waste generated during cutting. The control structure 900 is electrically connected to the feeding conveyor line 200, the unloading conveyor line 300, the flipping structure 400, the feeding and handling structure 500a, the unloading and handling structure 500b, the vision positioning structure, the cutting structure 700, and the waste collection structure 800, so as to coordinate the control of each structure to complete the automatic cutting of excess material in the material to be cut 1000.

[0096] In step S100, the orientation of the heat-sealing plate is adjusted by the flipping structure 400. The flipping structure 400 flips the heat-sealing plate 180° so that the convex side of the heat-sealing plate faces upward, thus obtaining the heat-sealing plate to be cut.

[0097] In step S200, the heat-sealed plate to be cut is conveyed to the feeding conveyor line 200, and the heat-sealed plate to be cut is picked up from the feeding conveyor line 200 by the feeding and handling structure 500a and moved to the cutting station of the cutting structure 700. In this application, the base 710 is the cutting station.

[0098] In step S300, the weld seam and the outline of excess material around the weld seam of the heat-sealed plate to be cut are identified by the visual positioning structure, and a cutting trajectory is generated.

[0099] In step S400, excess material around the weld is cut off by the cutting structure 700 according to the cutting trajectory.

[0100] In step S500, after the cutting is completed, the waste material is discharged into the waste collection structure 800.

[0101] In step S600, the cut heat-sealed plate is picked up from the cutting station of the cutting structure 700 and transferred to the unloading conveyor line 300 via the unloading and conveying structure 500b, and the cut heat-sealed plate is output to the next process via the unloading conveyor line 300.

[0102] The laser cutting method of this invention uses a laser cutting device to cut excess material around the weld of a heat-sealing plate. The orientation of the heat-sealing plate is adjusted by a flipping structure 400, which flips the plate 180° so that the convex side faces upwards, resulting in the heat-sealing plate to be cut. The plate is then picked up from the feeding conveyor line 200 by a feeding and conveying structure 500a and moved to the cutting station of the cutting structure 700. A visual positioning structure identifies the weld and the outline of the excess material around the weld of the heat-sealing plate to be cut, and generates a cutting trajectory. Based on the cutting trajectory, the cutting structure 700 cuts the excess material around the weld. After cutting, the excess material is removed. Waste material is discharged into the waste collection structure 800. The cut heat-sealed plate is then picked up from the cutting station of the cutting structure 700 and transferred to the unloading conveyor line 300 via the unloading transport structure 500b. The unloading conveyor line 300 then outputs the cut heat-sealed plate to the next process. By incorporating a flipping structure 400, a loading transport structure 500a, an unloading transport structure 500b, a vision positioning structure, a cutting structure 700, a waste collection structure 800, and a control structure 900 within the laser cutting equipment, and with the machine body 100 fixedly positioned between the loading conveyor line 200 and the unloading conveyor line 300, a continuous operation line of loading-cutting-unloading is formed. The flipping structure 400 is installed on the same side as the loading conveyor line 200 and connects with it, ensuring that the flipped material 1000 can directly enter the loading conveyor line 200. The loading and unloading conveying structure 500a is located at the output end of the loading conveyor line 200, and the unloading conveying structure 500b is located at the input end of the unloading conveyor line 300, ensuring that the transfer path accurately covers the loading conveyor line 200, the cutting station, and the unloading conveyor line 300. The visual positioning structure is used to identify the weld seam and the outline of the excess material around the weld seam of the material to be cut 1000, and generate a corresponding cutting trajectory. The cutting structure 700 is used to cut the excess material around the weld seam according to the cutting trajectory, which helps to improve the cutting accuracy, protect the integrity of the weld seam, accurately identify the boundary between the weld seam and irregular excess material, and ensure that the cut is continuous, flat, and burr-free.

[0103] The technical solution of this invention involves placing a waste collection structure 800 below the cutting structure 700 to collect waste generated during cutting, preventing waste from accumulating at the cutting station and affecting subsequent cutting accuracy. By setting up a control structure 900, which is electrically connected to the feeding conveyor line 200, the unloading conveyor line 300, the flipping structure 400, the feeding and handling structure 500a, the unloading and handling structure 500b, the vision positioning structure, the cutting structure 700, and the waste collection structure 800, the laser cutting equipment integrates fully automated functions for flipping, feeding, positioning, cutting, waste handling, and unloading. The feeding and handling structures 500a and 500b work synchronously, facilitating full-process collaborative control and improving batch cutting efficiency.

[0104] The laser cutting equipment in this invention features precise laser parameter tuning and control, which improves cutting speed, reduces the heat-affected zone, and minimizes deformation of the heat-sealed plate. Since the excess material around the weld seam of the ultra-thin heat-sealed plate has different shapes, a visual positioning structure is set up, and prior image recognition training is conducted to intelligently identify excess material on weld seams of different shapes. This optimizes the cutting trajectory of the cutting structure 700, achieving precise and efficient cutting of the excess weld material. To prevent waste accumulation from affecting the cutting effect, this invention incorporates a cleaning component 760, a dust extraction hood 770, and a waste collection structure 800. During the cutting process, the cleaning brush 761 automatically sweeps the waste into the waste trough, preventing waste accumulation on the base 710 and thus avoiding impact on the cutting effect.

[0105] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
