Technical Field

[0001] This invention relates to the field of cutting device technology, specifically a laser cutting device for processing aluminum single-panel panels. Background Technology

[0002] With the rapid development of electric vehicle-related services and decoration industries, the demand for thin-walled fluorocarbon coated aluminum panels for supporting building decoration and automotive interior and exterior trim for new energy vehicles continues to rise. These aluminum panels require batch processing of irregular decorative grooves with intersecting straight and curved lines, which places stringent requirements on the path adaptive adaptability, cutting accuracy, anti-deformation performance of the sheet material, and surface coating protection of laser cutting equipment.

[0003] Currently, traditional laser cutting equipment for aluminum panels generally suffers from significant technical shortcomings: it cannot achieve real-time adaptive attitude adjustment of the post-processing mechanism for cutting grooves with varying straight and curved paths; grinding and spraying actions are difficult to synchronize precisely with the texture processing trajectory; it has poor compatibility with cutting grooves of different depths and widths, requiring frequent changes of tooling molds or adjustments to the mechanical structure, resulting in insufficient versatility; the thermal stress generated during laser cutting easily causes thermal deformation of the aluminum panel, leading to distortion and displacement of decorative patterns; and the burrs and slag remaining on the cut surface after cutting cannot be processed online, requiring additional post-processing steps, making the processing flow cumbersome and production efficiency low; at the same time, the metal spatter and dust generated by laser cutting easily contaminate the lens of industrial cameras, leading to a decrease in detection accuracy; the linkage control effect of the components of spreading, grinding, and spraying is poor; and the overall automation level is low, making it difficult to meet the high-precision, high-efficiency, batch, and personalized processing requirements of aluminum panels for electric vehicles. Therefore, we propose a laser cutting device for aluminum panel processing. Summary of the Invention

[0015] Compared with the prior art, the present invention provides a laser cutting device for processing aluminum single panels, which has the following advantages: 1. The adapter component uses a first motor to drive gear meshing transmission, causing the moving frame to move in a circular motion along the guide ring. Combined with the guiding and anti-disengagement function of the chuck, it can precisely follow the cutting grooves along different paths, such as straight lines and curves, adjusting its posture to ensure that the grinding and spraying actions are aligned with the decorative trajectory throughout. The first electric actuator can drive the guide ring to rise and fall, adapting to the processing needs of cutting grooves of different depths. The opening component utilizes the meshing transmission of the first and second nautilus-shaped toothed plates, and achieves symmetrical adaptive opening through the power output of the third electric actuator. Combined with real-time detection feedback from an industrial camera, the opening range of the clamping plates can be flexibly adjusted according to the width of the cutting groove, adapting to various decorative patterns ranging from narrow slits to wide grooves. The entire device can complete the cutting processing of different styles and specifications of decorative patterns on the surface of aluminum panels without changing molds or adjusting the mechanical structure, greatly expanding the diversity of aluminum panel decorative design and meeting personalized needs.

[0016] 2. The shaping component employs a flexible clamping structure combining a high-temperature resistant elastic pressure plate and springs. During the cutting process, it continuously clamps the aluminum panel around the cutting groove, effectively suppressing panel deformation caused by thermal stress from laser cutting. This ensures the flatness of the panel around the decorative groove and prevents pattern distortion or misalignment. The friction component drives three flexible grinding shafts to rotate synchronously via the meshing of a bevel gear and a fourth gear. These shafts perform comprehensive grinding of the inner wall, upper edge, and corners of the cutting groove, thoroughly removing metal burrs, slag, and rough surfaces, resulting in a smooth cut without the need for additional post-processing. The atomizing spray head adaptively deflects with the opening of the clamping plate, precisely spraying coating liquid onto the cutting area. This forms a protective layer on the cutting surface to prevent metal oxidation and rust, while also cooling and lubricating the grinding area, preventing high-temperature damage to the aluminum panel surface coating and ensuring the decorative effect and service life of the processed aluminum panel.

[0017] 3. The industrial camera is equipped with a transparent protective film to prevent metal splatter and dust from directly adhering to the lens. A second motor drives gear transmission to rotate the protective film at high speed, using centrifugal force for self-cleaning. This, combined with a connecting plate, ensures stable gear meshing, guaranteeing accurate test data and providing a reliable basis for component adaptation and adjustment. All moving components adopt a symmetrical design and precise guiding structure: the universal wheels of the shaping component reduce movement resistance and prevent damage to the sheet coating; the guide strips of the spreading component restrict the movement trajectory of the second toothed plate, preventing deviation and jamming; the fixing frame of the friction component provides stable support for the atomizing spray head, ensuring accurate spray direction. The entire device, through the coordinated control of the longitudinal and transverse moving platforms and the cutting machine body, combined with the automated linkage of various functional components, achieves fully automated processing from aluminum sheet loading, positioning, and cutting to anti-deformation, grinding, and anti-oxidation, eliminating the need for frequent manual intervention. This improves processing efficiency and ensures consistency and stability during mass production. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] The following electrical components are all electrically connected via an external PLC controller.

[0022] Please see Figures 1-9 A laser cutting device for processing aluminum single panels includes a worktable 1, a conveyor belt on the inner side of the worktable 1, a longitudinal moving platform 2 on the upper end of the worktable 1, a transverse moving platform 3 on the upper end of the longitudinal moving platform 2, a cutting machine body 4 installed at the output end of the transverse moving platform 3, a lifting function on the inner side of the cutting machine body 4, a guide mechanism 5 for adapting to the cutting groove installed at the lower end of the housing of the cutting machine body 4, a grinding mechanism 6 for processing the cutting groove installed on the inner side of the guide mechanism 5, and a coating liquid tank 7 fixedly connected to the lower end of the housing of the cutting machine body 4.

[0023] In this embodiment, the guide mechanism 5 includes an adapter component 51 for positioning and adapting to the cutting groove path, and the guide mechanism 5 also includes a shaping component 52 for preventing thermal deformation around the cutting groove.

[0024] Specifically, the guiding mechanism 5 provides dual protection for laser cutting: the adapter component 51 can adjust its posture in real time to follow the path changes of the cutting groove in straight lines and curves, ensuring that subsequent grinding and spraying actions are precisely aligned with the cutting groove; the shaping component 52 can flexibly press the aluminum single plate around the cutting groove during the laser cutting process to suppress the deformation of the metal sheet caused by thermal stress. The two work together to ensure the path accuracy of metal cutting and the flatness of the sheet.

[0025] In this embodiment, the adapter component 51 includes a plurality of first electric actuators 511. The output shafts of the plurality of first electric actuators 511 are fixedly connected to a connecting frame 512. A guide ring 513 is fixedly connected to the outer side of the connecting frame 512. A toothed ring 514 is fixedly connected to the lower end of the guide ring 513. A movable frame 515 is slidably connected to the outer side of the guide ring 513. A first motor 516 is mounted on the upper end of the movable frame 515. A first gear 518 is rotatably connected to the inner side of the movable frame 515. The outer side of the first gear 518 is meshed with the toothed ring 514. The output shaft of the first motor 516 is fixedly connected to the first gear 518. At least two sets of symmetrical chucks 517 are rotatably connected to the inner side of the movable frame 515. The outer sides of the two sets of chucks 517 are slidably connected to the inner and outer sides of the guide ring 513, respectively.

[0026] Specifically, the various components of the adapter component 51 work together to achieve the adaptation of the cutting groove path: multiple first electric push rods 511 can synchronously extend and retract to drive the connecting frame 512 to raise and lower the guide ring 513 as a whole, thereby adjusting the height of the grinding mechanism 6 to adapt to cutting grooves of different depths; the first motor 516 drives the first gear 518 to rotate, and through the meshing transmission between the first gear 518 and the retaining ring 514, it drives the moving frame 515 to make circumferential motion along the guide ring 513 to adapt to the path changes of the curved cutting groove; two sets of symmetrical retaining wheels 517 respectively roll and cooperate with the inner and outer sides of the guide ring 513, which not only restricts the movement trajectory of the moving frame 515 and prevents it from falling off, but also reduces the movement resistance, ensuring the stability of the path adaptation and ensuring the precise synchronization of the metal cutting post-processing actions.

[0027] In this embodiment, a second motor 5110 is installed at the lower end of the moving frame 515. A connecting plate 5111 is rotatably connected to the outer side of the housing of the second motor 5110. An industrial camera 519 is installed at the other end of the connecting plate 5111. The upper end of the industrial camera 519 is fixedly connected to the moving frame 515. A second gear 5112 is fixedly connected to the output shaft of the second motor 5110. A third gear 5113 is meshed with the outer side of the second gear 5112. The inner side of the third gear 5113 is rotatably connected to the lens of the industrial camera 519. A protective sheet 5114 is fixedly connected to the lower end of the third gear 5113. The protective sheet 5114 is made of transparent material.

[0028] Specifically, the industrial camera 519 is used to collect real-time data on the width, depth, and cross-sectional shape of the cutting groove, providing precise feedback for adjusting the opening degree of the expansion component 61 and the posture of the guide mechanism 5, ensuring that the post-processing actions are compatible with the cutting groove; the transparent protective sheet 5114 can prevent metal spatter and dust generated by laser cutting from directly adhering to the lens of the industrial camera 519, avoiding a decrease in detection accuracy; the second motor 5110 drives the second gear 5112 to rotate, and through meshing with the third gear 5113, drives the protective sheet 5114 to rotate at high speed, using centrifugal force to shake off the dirt adhering to the surface, achieving self-cleaning; the connecting plate 5111 is connected to the rotation of the second motor 5110 and the industrial camera 519 at both ends respectively, ensuring that the second gear 5112 and the third gear 5113 always maintain stable meshing, ensuring the continuous reliability of the self-cleaning function.

[0029] In this embodiment, the shaping component 52 includes two mutually symmetrical second electric push rods 521. The second electric push rods 521 are installed on both sides of the movable frame 515. The output shaft of the second electric push rod 521 is fixedly connected to a slide rod 522. A pressure block 523 is slidably connected to the outer side of the slide rod 522. A universal wheel is provided at the lower end of the pressure block 523. An elastic pressure plate 524 is fixedly connected to both the front and rear ends of the pressure block 523. The elastic pressure plate 524 is made of high temperature resistant material. A spring 525 is provided on the outer side of the slide rod 522. One end of the spring 525 is fixedly connected to the slide rod 522, and the other end of the spring 525 is fixedly connected to the pressure block 523.

[0030] Specifically, two symmetrical second electric push rods 521 provide power for the clamping action, driving the slide rod 522 to move the pressure block 523 downward; the high-temperature resistant elastic pressure plate 524 fits against the aluminum single plates on both sides of the cutting groove, and the elastic restoring force of the spring 525 achieves flexible clamping, effectively suppressing the thermal deformation of laser cutting; the universal wheel at the lower end of the pressure block 523 converts sliding friction into rolling friction, ensuring that the shaping component 52 moves synchronously with the main body 4 of the cutting machine, without additional resistance and without damaging the surface coating of the aluminum single plate.

[0031] In this embodiment, the grinding mechanism 6 includes a spreading component 61 for adapting to the cutting groove, and the grinding mechanism 6 also includes a friction component 62 for grinding the cutting groove.

[0032] Specifically, the opening component 61 can adaptively adjust the opening range according to the width of the cutting groove, so that the friction component 62 fits tightly with the inner wall of the cutting groove; the friction component 62 is responsible for simultaneously grinding the inner wall, upper edge and corner of the cutting groove to remove the metal burrs, slag and rough cross-sections left by laser cutting. The two work together to achieve integrated post-cutting processing, improving the processing accuracy and surface quality of the aluminum single-panel cutting groove.

[0033] In this embodiment, the spreading assembly 61 includes a third electric actuator 611 disposed at the front end of the movable frame 515. The output shaft of the third electric actuator 611 is slidably connected to a sleeve 612. The outer side of the sleeve 612 is fixedly connected to the movable frame 515. The lower end of the sleeve 612 is fixedly connected to a mounting shell 613. The output shaft of the third electric actuator 611 is rotatably connected to two mutually symmetrical connecting rods 614 via a rotating shaft. The front end of the connecting rod 614 is rotatably connected to a first toothed plate 615 via a rotating shaft. The first toothed plate 615 is designed as a nautilus gear. The axis of the first toothed plate 615 is rotatably connected to the inner side of the mounting shell 613 via a rotating shaft.

[0034] Specifically, the spreading assembly 61 achieves adaptive spreading through a transmission mechanism: the third electric actuator 611 provides power for the spreading action, and its output shaft slides along the sleeve 612. The sleeve 612 not only guides the output shaft, but also provides installation support for the entire spreading assembly 61 through its fixed connection with the moving frame 515 and the mounting shell 613. The mounting shell 613 provides a closed installation space for the internal transmission components such as the connecting rod 614 and the first toothed plate 615, preventing metal splashes from affecting the transmission accuracy. The output shaft of the third electric actuator 611 drives the two symmetrical connecting rods 614 to deflect through the rotating shaft, which in turn pulls the first toothed plate 615, which is designed with a nautilus gear, to rotate around the rotating shaft inside the mounting shell 613. The nautilus gear structure can convert the rotation of the first toothed plate 615 into the smooth linear motion of the second toothed plate 616, ensuring the uniformity of the spreading action.

[0035] In this embodiment, the outer sides of the two first toothed plates 615 are meshed with second toothed plates 616, the rear ends of the two second toothed plates 616 are slidably connected with guide bars 617, the guide bars 617 are fixedly connected to the inner side of the mounting shell 613, and the lower ends of the two second toothed plates 616 are fixedly connected with mutually symmetrical support bars 618.

[0036] Specifically, this part of the component realizes the transmission and guidance of the spreading force: the two first toothed plates 615, through meshing with the second toothed plate 616, convert their own rotational motion into the linear motion of the second toothed plate 616, and because the first toothed plates 615 are symmetrically arranged, it can ensure that the two second toothed plates 616 move synchronously in opposite directions; the guide strip 617 restricts the movement trajectory of the second toothed plate 616 to prevent the second toothed plate 616 from deviating and ensure the linear accuracy of the spreading action; the support strip 618 is fixedly connected to the lower end of the second toothed plate 616 to transmit the spreading force, drive the clamping plate 621 of the friction assembly 62 to open or close synchronously, and achieve precise adaptation with the width of the cutting groove.

[0037] In this embodiment, the friction assembly 62 includes two symmetrical clamping plates 621. One side of the clamping plate 621 is fixedly connected to the support bar 618. The inner side of the clamping plate 621 is rotatably connected to a bevel gear 622 via a rotating shaft. The outer side of the bevel gear 622 is meshed with two symmetrical fourth gears 623. The fourth gears 623 are rotatably connected to the inner side of the clamping plate 621 via a rotating shaft. A flexible grinding shaft 624 is fixedly connected to the same end of both the bevel gear 622 and the fourth gears 623. A third motor 625 is installed at the upper end of the clamping plate 621. The output shaft of the third motor 625 is fixedly connected to one of the corresponding fourth gears 623 below.

[0038] Specifically, the friction assembly 62 achieves multi-directional synchronous grinding through gear transmission: the clamping plate 621 provides mounting support for the internal bevel gear 622, the fourth gear 623, and the flexible grinding shaft 624, and adjusts its position synchronously with the spread assembly 61 through a fixed connection with the support bar 618; the third motor 625 provides power for the grinding action, and its output shaft drives the corresponding fourth gear 623 to rotate. The fourth gear 623 drives the bevel gear 622 to rotate through meshing with it, and the bevel gear 622 further drives another set of symmetrical fourth gears 623 to rotate synchronously; the fourth gear 623 and the bevel gear 622 respectively drive their respective fixed flexible grinding shafts 624 to rotate at high speed. The three flexible grinding shafts 624 correspond to the inner wall, upper edge, and corner of the cutting groove, respectively, to achieve multi-directional synchronous grinding, effectively removing metal burrs and slag. The flexible material can adapt to the shape changes of the cutting groove and avoid scratching the cut surface.

[0039] In this embodiment, the friction assembly 62 includes two mutually symmetrical L-shaped rods 626. One side of the L-shaped rod 626 is fixedly connected to the clamping plate 621, and the other end of the L-shaped rod 626 is rotatably connected to an atomizing spray head 627 via a rotating shaft. The lower part of the L-shaped rod 626 on the outer side of the atomizing spray head 627 is rotatably connected to a fixing frame 628 via a rotating shaft. The other end of the fixing frame 628 is fixedly connected to the mounting shell 613, and the inlet of the atomizing spray head 627 is fixedly connected to the coating liquid tank 7 via a hose.

[0040] Specifically, the L-shaped rod 626 acts as a transmission medium, moving synchronously with the opening or closing of the clamping plate 621. This, in turn, drives the atomizing spray head 627 to deflect around the axis of the fixed frame 628, achieving adaptive alignment between the spray direction and the width of the cutting groove. The wider the cutting groove, the closer the spray angle. The fixed frame 628 provides rotational support for the atomizing spray head 627, ensuring smooth deflection. The atomizing spray head 627 draws coating liquid from the coating liquid tank 7 through a hose and sprays it in atomized form onto the inner wall of the cutting groove and the grinding area. This prevents oxidation and rust on the metal cut and cools and lubricates the flexible grinding shaft 624 and the cutting area, avoiding damage to the aluminum single-panel surface coating due to high temperatures and ensuring processing quality.

[0041] Working principle: During use, the aluminum panel is placed on the conveyor belt inside the workbench 1. The conveyor belt accurately transports the aluminum panel to the preset processing station, completing the automatic feeding and positioning of the metal sheet. Then, through the coordinated movement of the longitudinal moving platform 2 and the transverse moving platform 3, the cutting machine body 4 is accurately moved to the preset cutting starting point. The cutting machine body 4 adjusts its height through the built-in lifting mechanism and is accurately positioned at the preset cutting height. Under the trajectory control of the longitudinal moving platform 2 and the transverse moving platform 3, the aluminum panel is laser-cut along the set path to form the required decorative groove. During the laser cutting process, the shaping component 52 of the guide mechanism 5 is activated first: the second electric push rod 521 is activated, and its output shaft drives the pressure block 523 downward through the slide rod 522 until the high-temperature resistant elastic pressure plates 524 at both ends of the pressure block 523 are in contact with the aluminum single-plate surfaces on both sides of the cutting groove; the second electric push rod 521 continuously outputs thrust, which, together with the pressure block 523, compresses the spring 525 on the outside of the slide rod 522. The elastic restoring force of the spring 525 causes the elastic pressure plate 524 to flexibly press the aluminum single-plate, effectively suppressing the thermal deformation of the metal sheet caused by the thermal stress generated by laser cutting; the universal wheel at the lower end of the pressure block 523 rolls in contact with the surface of the aluminum single-plate, ensuring that when the shaping component 52 moves synchronously with the main body of the cutting machine 4, no additional resistance is generated and the coating on the surface of the aluminum single-plate is not damaged; The grinding mechanism 6 is started synchronously, and the specific actions are as follows: First, the first electric push rod 511 of the adapter component 51 extends, driving the connecting frame 512 and the guide ring 513 to move downward as a whole, thereby driving the grinding mechanism 6 to move downward synchronously, so that the two sets of clamping plates 621 of the friction component 62 are precisely embedded into the cutting groove; then, the third electric push rod 611 that opens the component 61 is started, and its output shaft extends downward along the sleeve 612, driving the two sets of symmetrical connecting rods 614 to deflect around the rotating axis, and the connecting rods 614 pull... The first toothed plate 615 of the nautilus-shaped gear design rotates around the pivot inside the mounting housing 613; the first toothed plate 615 drives the second toothed plate 616 to move in a straight line towards each other along the guide bar 617 through tooth surface meshing; the second toothed plate 616 drives the support bar 618 fixedly connected at the lower end to open synchronously; under the real-time detection feedback of the industrial camera 519, it adaptively adapts to the width of the cutting groove, so that the clamping plate 621 drives the flexible grinding shaft 624 to fit tightly against the inner wall of the cutting groove; Grinding action initiated: The third motor 625 outputs power to drive the corresponding fourth gear 623 below to rotate. The fourth gear 623 drives the bevel gear 622 to rotate through tooth surface meshing. The bevel gear 622 further drives another set of symmetrical fourth gears 623 to rotate synchronously. The fourth gear 623 and the bevel gear 622 synchronously drive their respective fixedly connected high-temperature resistant flexible grinding shafts 624 to rotate at high speed, simultaneously grinding the inner wall, upper edge and corner of the cutting groove to remove the metal burrs, slag and rough cross-sections remaining after laser cutting, ensuring that the metal cut is flat and smooth. As the clamping plate 621 opens along with the spreading assembly 61, the clamping plate 621 drives the L-shaped rod 626 to move synchronously. The L-shaped rod 626 pushes the atomizing spray head 627, which is initially in a vertical state, causing the atomizing spray head 627 to deflect counterclockwise around the axis of the fixed frame 628. The wider the cutting groove, the greater the opening amplitude of the clamping plate 621, and the greater the deflection angle of the atomizing spray head 627, so as to achieve precise alignment of the spraying direction with the cutting groove. The atomizing spray head 627 draws coating liquid from the coating liquid tank 7 through a hose and sprays it in atomized form onto the inner wall of the cutting groove and the grinding area to prevent oxidation and rust on the inner wall of the metal cutting groove. At the same time, it cools and lubricates the flexible grinding shaft 624 and the cutting area to avoid damage to the coating on the surface of the aluminum single panel due to high temperature. When the main body 4 of the cutting machine cuts along the curved trajectory, the path angle of the cutting groove changes in real time: the first motor 516 of the adapter component 51 is started, and its output shaft drives the first gear 518 to rotate. The first gear 518 meshes with the tooth surface of the toothed ring 514, driving the moving frame 515 to make a circular motion along the guide ring 513. The two sets of symmetrical chucks 517 on the inner side of the moving frame 515 respectively roll in contact with the inner and outer sides of the guide ring 513, which reduces the moving resistance and ensures that the moving frame 515 does not disengage from the guide ring 513, so that the grinding mechanism 6 can adjust its posture in real time to follow the laser cutting path and accurately adapt to the angle change of the cutting groove. At the same time, the first electric push rod 511 drives the guide ring 513 to make up and down fine adjustments through the connecting frame 512. In conjunction with the industrial camera 519 at the lower end of the moving frame 515, the width, depth and cross-sectional shape data of the cutting groove are collected in real time, providing accurate feedback for the opening degree adjustment of the opening component 61 and the posture adjustment of the guide mechanism 5, ensuring that the grinding and spraying actions are fully adapted to the cutting path. Metal spatter, fumes, and other contaminants generated during laser cutting easily adhere to the lower end of the lens protective sheet 5114 of the industrial camera 519, affecting detection accuracy. The second motor 5110 is activated, its output shaft driving the second gear 5112 to rotate. The second gear 5112, through tooth surface meshing, drives the third gear 5113 to rotate. The third gear 5113 drives the transparent protective sheet 5114, fixedly connected to its lower end, to rotate at high speed. Centrifugal force is used to fling away the metal contaminants and fumes adhering to the surface of the protective sheet 5114, achieving self-cleaning of the protective sheet 5114. The connecting plate 5111 on the outer side of the second motor 5110 housing is rotatably connected to both the second motor 5110 and the industrial camera 519, ensuring that the second gear 5112 and the third gear 5113 maintain a stable meshing state, guaranteeing the continuous reliability of the self-cleaning function, and thus ensuring the detection accuracy of the industrial camera 519.
