Description

Technical Field

[0001] This invention relates to the field of outdoor decorative aluminum plate welding equipment, and more particularly to an outdoor decorative aluminum plate welding device. Background Technology

[0002] As a mainstream material for modern building curtain walls and outdoor decorative components, aluminum gray outdoor decorative aluminum panels are widely used in outdoor decoration projects of large stadiums, commercial complexes, transportation hubs and landmark buildings due to their advantages such as light weight, weather resistance, beauty and easy processing.

[0003] Please see Figure 1 The outdoor decorative aluminum panel structure shown mainly includes a frame structure and a decorative panel structure fixed inside the frame.

[0004] Currently, welding of outdoor decorative aluminum panels mainly relies on manual hand-held welding torches and simple clamps for positioning. Operators first place the frame structure to be assembled on the workbench, then press the edges of the decorative panel structure firmly. They then manually measure and adjust the joint gaps, and perform spot welding segment by segment until a continuous full weld is achieved. While this traditional method is usable, the joint gaps between the decorative aluminum panels are difficult to control because the panel structure is typically a thin-walled, large-panel structure, resulting in decreased weld quality and reduced processing efficiency. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide an outdoor decorative aluminum plate welding device to solve the problem that, in the welding operation of outdoor decorative aluminum plates, when welding manually, the gap between the raw materials of the decorative aluminum plates is difficult to control because the structure of the decorative plate is usually a thin-walled large-panel structure, resulting in a decrease in the quality of the weld formation and affecting the processing efficiency.

[0006] To achieve the above objectives, the present invention provides an outdoor decorative aluminum plate welding device, comprising:

[0007] The frame has a rotating frame capable of rotating about the vertical direction;

[0008] The welding module is fixedly connected to the frame and has a welding end that can move with multiple degrees of freedom;

[0011] Several sets of clamping telescopic cylinders are symmetrically fixed on the first clamping platform and the second clamping platform, respectively. Each clamping telescopic cylinder has a telescopic clamping end that can move and rotate vertically, and a clamping block is fixed on the telescopic clamping end.

[0012] The positioning components are fixed to the first clamping platform and the second clamping platform respectively, and are used to position the outdoor decorative aluminum plate.

[0013] Four sets of symmetrically arranged side support components are respectively symmetrically fixed on the first clamping platform and the second clamping platform. Each side support component has a rotating bracket with its rotation center line arranged vertically. An abutment block is installed on the rotating bracket by rotation. The abutment block is provided with an abutment end that can abut against the inner wall of the outdoor decorative aluminum panel. A cooling air duct is provided inside the side support component and faces the inner wall of the outdoor decorative aluminum panel.

[0014] In an optional example, two sets of movable guide rails and drive motors are fixed on the rotating frame along its width direction. The lower end of the second clamping platform is fixed with a movable slider and drive nut that match the movable guide rails. The movable slider is slidably fitted onto the movable guide rails. A drive screw is installed on the rotating frame along its width direction by means of a bearing connection. The drive nut is fitted onto the outer wall of the drive screw by means of a threaded connection. The output shaft of the drive motor is fixedly connected to the drive screw and drives the drive screw to rotate.

[0015] In an optional example, the side support assembly includes a side bracket fixedly connected to the rotating frame, a support base fixedly mounted on the side bracket, a side rotating shaft mounted vertically on the support base via rotation, the rotating bracket fixed to the upper end of the side rotating shaft, a rotating gear fixedly fitted on the lower part of the rotating bracket, a side telescopic cylinder fixedly mounted on the side bracket, and a sliding rack slidably mounted on the side bracket along the length direction of the rotating frame, the sliding rack meshing with the rotating gear.

[0016] In an optional example, both the first clamping platform and the second clamping platform have side grooves along the length of the rotating frame and pass through the corresponding first clamping platform and second clamping platform vertically. A side slider is slidably inserted in the side groove. A side threaded hole is opened on the side bracket. A side bolt is inserted on the side slider. The side bolt is fixed in the side threaded hole by a threaded connection.

[0017] In an optional example, the contact end is provided with a sidewall groove extending toward the center of the outdoor decorative aluminum panel, so that there is a flow gap between the sidewall groove and the outdoor decorative aluminum panel, and the outlet of the cooling air duct is located in the sidewall groove.

[0018] In an optional example, the end of the side rotating shaft has a bottom hole along the axial direction, and the outer wall of the side rotating shaft has several side wall through holes communicating with the bottom hole. The rotating bracket has a first rotating hole and a second rotating hole. The side rotating shaft is inserted into the first rotating hole by a key connection. A first venting ring groove is formed in the first rotating hole, and the first venting ring groove communicates with the side wall through holes. A second venting ring groove is formed in the first rotating hole. The rotating bracket has a bracket flow channel. The channel is connected to the first ventilation ring groove and the second ventilation ring groove. The lower end of the contact block is provided with a downwardly extending contact shaft. The contact shaft is inserted into the second rotating hole by rotation. The contact block has a contact flow channel. One end of the contact flow channel passes through to the outer wall of the contact shaft and is connected to the second ventilation ring groove. The other end of the contact flow channel passes through to the side wall groove. The bottom hole, the side wall through hole, the support flow channel, the first ventilation ring groove, the second ventilation ring groove and the contact flow channel are connected and combined to form a cooling air duct.

[0019] In one optional example, a plurality of positioning slots are provided on the outer wall of the abutment shaft, an elastic positioning piece is fixed on the rotating bracket, and an elastic abutment head is provided on the elastic positioning piece. The elastic abutment head can be inserted into the positioning slot and restricts the rotation of the abutment shaft by its own elasticity.

[0020] In an alternative example, a central support assembly is fixed to the rotating frame, the central support assembly having a central support end capable of moving with multiple degrees of freedom.

[0021] In an optional example, the central support assembly includes a first bracket fixedly connected to the rotating frame. A guide slide rod is provided on the first bracket along the width direction of the rotating frame. A guide sleeve is slidably fitted on the outer wall of the guide slide rod. A sleeve bolt is installed on the guide sleeve by a threaded connection. The end of the sleeve bolt can abut against the outer wall of the guide slide rod and fix the guide sleeve in a relative position. A second bracket is fixed on the guide sleeve. A third bracket is slidably installed on the second bracket along the vertical direction. An adjusting screw is rotatably installed at the lower end of the third bracket. An adjusting through hole is opened on the second bracket along the vertical direction. The adjusting screw passes through the adjusting through hole. A locking nut is threadedly fitted on the outer wall of the adjusting screw. The locking nut abuts against the second bracket. The central support end is located at the upper end of the third bracket.

[0022] In an optional example, a negative pressure module is fixed on the third bracket. The negative pressure module has a negative pressure end that is at the same horizontal height as the middle support end and is used to fix the outdoor decorative aluminum panel.

[0023] The beneficial effects of this invention are as follows: through the cooperation of the welding module, the first clamping platform, the second clamping platform, the clamping telescopic cylinder, the positioning block, and the side support assembly, the decorative aluminum plate is clamped quickly. A uniform vertical clamping force is applied to the decorative aluminum plate from above, preventing the aluminum plate from shifting and warping during welding. This ensures strict control over the precision of the joint gap between the decorative aluminum plate materials, improving weld formation quality and welding efficiency. Simultaneously, the side support assembly integrated on the clamping platform provides stable lateral support from the inside of the decoration, enhancing the structural rigidity of the aluminum plate during high-temperature welding and resisting dents or wave deformation caused by thermal stress. Furthermore, the cooling air duct integrated inside the side support assembly accurately delivers cold air to the inner wall of the welding heat-affected zone, achieving a conformal cooling effect while welding, reducing the heat input and residual stress of the aluminum plate, and preventing welding deformation of large outdoor thin-walled aluminum plates. Finally, the second clamping platform's relative distance to the first clamping platform is adjustable via a sliding mechanism, allowing for rapid adaptation to aluminum plates of different widths, reducing equipment investment costs and changeover time.

[0042] In one embodiment, please refer to Figures 1 to 3 As shown, the present invention provides an outdoor decorative aluminum plate welding device, including a frame 1, a welding module 2, a first clamping table 3, a second clamping table 4, a clamping telescopic cylinder 5, a positioning block 6, and a side support assembly 7.

[0043] The bottom of the frame 1 is fixed to the ground, and the upper part of the frame 1 is provided with a rotating frame 101 driven by a servo motor. The rotating frame 101 can rotate around the vertical axis in the range of 0° to 360° to adjust the orientation of the aluminum plate to be welded so that the welding module 2 can perform welding.

[0044] The welding module 2 is fixedly connected to the frame 1 by bolts and has a welding end 201 capable of multi-degree-of-freedom movement. It adopts a six-axis industrial robot. The welding end 201 includes a laser welding head and a roller pressing structure. The roller pressing structure is set on both sides of the laser welding head to avoid interfering with the laser's optical path.

[0045] The first clamping platform 3 is fixed to one side of the rotating frame 101 by bolt connection. The first clamping platform 3 is a fixed structure.

[0046] The second clamping platform 4 is fixed to the other side of the rotating frame 101 by sliding along the width direction of the rotating frame 101, and can move toward or close to the first clamping platform 3.

[0047] The clamping telescopic cylinder 5 comprises four sets symmetrically fixed to the first clamping platform 3 and the second clamping platform 4 by bolt connection. The clamping telescopic cylinder 5 has a telescopic clamping end that can move and rotate vertically, and a clamping block 501 is fixed on the telescopic clamping end. Among them, two sets of clamping telescopic cylinders 5 are fixed at the front and rear ends of the first clamping platform 3, and the other two sets of clamping telescopic cylinders 5 are fixed at the front and rear ends of the second clamping platform 4, forming a symmetrical arrangement. Each set of clamping telescopic cylinders 5 can be hydraulic, electric or pneumatic, and its telescopic end integrates a rotating structure, forming a telescopic clamping end that can move vertically and rotate around the vertical axis. A rubber clamping block 501 is fixedly installed at the end of the telescopic clamping end. During clamping, the telescopic end of the clamping telescopic cylinder 5 rotates to a set angle and then moves downward until the clamping block 501 presses against the upper surface of the aluminum plate to adapt to the structure of the edge of the aluminum plate.

[0048] The positioning assembly includes four symmetrically arranged positioning blocks 6, which are fixed to the first clamping platform 3 and the second clamping platform 4 by bolts and are arranged diagonally. Each positioning block 6 has a positioning groove 601 that matches the diagonal position of the outdoor decorative aluminum panel. The four corners of the outdoor decorative aluminum panel are respectively embedded in the corresponding positioning grooves 601, achieving rapid fixing of the outdoor decorative aluminum panel.

[0049] Four symmetrically arranged side support components 7 are fixed to the first clamping platform 3 and the second clamping platform 4, respectively. Each component has a rotating bracket 71 with its rotation centerline vertically aligned. An abutment block 72 is mounted on the rotating bracket 71 by rotation. The abutment block 72 has an abutment end 721 that can abut against the inner wall of the outdoor decorative aluminum panel. A cooling air duct 701 is provided inside the side support components 7, facing the inner wall of the outdoor decorative aluminum panel. The cooling air duct 701 is connected to a compressed cold air source via a flexible air pipe.

[0050] Working principle:

[0051] Step 1: First, the second clamping platform 4 moves away from the first clamping platform 3 to a set position under the drive of the lead screw, and the diagonal corners of the outdoor decorative aluminum panel frame structure are respectively placed into the V-shaped positioning grooves 601 of the two positioning blocks 6 on the first clamping platform 3. Then, the middle part of the outdoor decorative aluminum panel is placed into the outdoor decorative aluminum panel frame structure. At this time, the second clamping platform 4 is moved closer to the first clamping platform 3 until the diagonal corners of the outdoor decorative aluminum panel frame structure are engaged in the positioning grooves 601 of the two positioning blocks 6 on the second clamping platform 4.

[0052] Step 2: The side support component 7 is working. The rotating bracket 71 rotates and moves, causing the contact end 721 of the contact block 72 to fit tightly against the reinforcing rib or the inner wall of the folded edge on the inner side of the aluminum plate, providing lateral support force for the aluminum plate and preventing inward deformation due to thermal stress during welding.

[0053] Step 3: The telescopic clamping cylinder 5 operates, and the telescopic clamping end moves vertically downward, so that the clamping block 501 presses against the upper surface of the outdoor decorative aluminum plate.

[0054] Step 4: Start welding module 2, which drives the laser welding head to perform precise welding along the joint between the two aluminum plates. During the welding process, external compressed cold air is continuously blown onto the welded inner wall of the outdoor decorative aluminum plate through cooling duct 701 to remove excess heat and control welding deformation.

[0055] Step 5: After welding is completed, the clamping telescopic cylinder 5 is activated, the telescopic end retracts, the side support component 7 is reset, the second clamping table 4 is removed, and the welded large aluminum plate component is hoisted and removed.

[0056] Specifically, this example utilizes the cooperation of welding module 2, first clamping platform 3, second clamping platform 4, clamping telescopic cylinder 5, positioning block 6, and side support assembly 7 to achieve rapid clamping of decorative aluminum panels. This allows for the application of uniform vertical clamping force from above, preventing the aluminum panels from shifting and warping during welding. This ensures strict control over the precision of the joint gaps between the decorative aluminum panel raw materials, improving weld quality and welding efficiency. Simultaneously, the integrated side support assembly 7 on the clamping platform provides stable lateral support from the inside of the decoration, enhancing... The structural rigidity of the aluminum plate during high-temperature welding resists the dents or wave deformations caused by thermal stress. Furthermore, the cooling air duct 701 integrated inside the side support component 7 can accurately deliver cold air to the inner wall of the welding heat-affected zone, achieving a conformal cooling effect of welding and cooling simultaneously. This reduces the heat input and residual stress of the aluminum plate, and avoids welding deformation of large outdoor thin-walled aluminum plates. Finally, the second clamping table 4 is adjustable relative to the first clamping table 3 through a sliding mechanism, which can quickly adapt to aluminum plates of different widths and sizes, reducing equipment investment costs and changeover time.

[0057] In an optional example, please refer to Figures 1 to 4 As shown, two sets of movable guide rails 11 and drive motors 12 arranged along their width direction are fixed on the rotating frame 101 by bolt connection. The lower end of the second clamping platform 4 is fixed with a movable slider 13 and a drive nut 14 that match the movable guide rails 11 by bolt connection. The movable slider 13 is slidably fitted on the movable guide rails 11. A drive screw 15 arranged along its width direction is installed on the rotating frame 101 by bearing connection. The drive nut 14 is fitted on the outer wall of the drive screw 15 by thread connection. The output shaft of the drive motor 12 is fixedly connected to the drive screw 15 by a coupling and drives the drive screw 15 to rotate.

[0058] Specifically, when the drive motor 12 is working, the output shaft drives the drive screw 15 to rotate through the coupling, and the drive nut 14 moves along the screw axis, thereby driving the second clamping table 4 to move under the guidance of the moving guide rail 11 and the moving slider 13, ensuring the movement accuracy and stability of the second clamping bar.

[0059] In an optional example, please refer to Figures 1 to 11 As shown, the side support assembly 7 includes a side bracket 73 fixedly connected to the rotating frame 101 by bolts. A support base 74 is fixed to the side bracket 73 by bolts. A side rotating shaft 75 is mounted vertically on the support base 74 by rotation. A rotating bracket 71 is fixed to the upper end of the side rotating shaft 75. A rotating gear 76 is fitted onto the lower part of the rotating bracket 71 by a key connection. A side telescopic cylinder 77 is fixed to the side bracket 73 by bolts. A sliding rack 78 is slidably mounted on the side bracket 73 along the length of the rotating frame 101, and the sliding rack 78 meshes with the rotating gear 76. A rack guide rail 79 is provided on the side bracket 73, and a rack slider 710 is slidably mounted on the rack guide rail 79. The rack slider 710 and the sliding rack 78 are fixedly connected by bolts. The side telescopic cylinder 77 can be hydraulic, electric, or pneumatic, preferably electric, to facilitate control of the movement distance of the sliding rack 78.

[0060] Specifically, in this example, the side support assembly 7 adopts a sliding engagement structure of rack and pinion guide rail 79 and rack and pinion slider 710, which provides precise linear motion guidance for the sliding rack 78, ensuring the stability and transmission accuracy of the gear and rack meshing. Furthermore, by controlling the extension of the electric cylinder, the rotation angle of the rotating bracket 71 can be precisely adjusted, allowing the contact end 721 to be adjusted to the optimal support position according to the inner wall shape of different aluminum plates. This achieves fine control of the support angle and further improves the welding quality of the welding device.

[0061] In an optional example, please refer to Figures 1 to 11 As shown, both the first clamping platform 3 and the second clamping platform 4 have side sliding grooves 301 along the length of the rotating frame 101, and these grooves extend vertically through the corresponding first clamping platform 3 and second clamping platform 4. A side slider 16 is slidably inserted into the side sliding groove 301. A side threaded hole is provided on the side bracket 73. A side bolt 17 is inserted into the side slider 16. The side bolt 17 is fixed in the side threaded hole by a threaded connection.

[0062] Specifically, in this example, side grooves 301 are opened along the length direction on the first clamping table 3 and the second clamping table 4, and the side bracket 73 is slidably fixed on the clamping table by the cooperation of the side slider 16 and the side bolt 17. This allows the side support assembly 7 to be adjusted in position along the length direction of the rotating frame 101. Thus, the support point of the abutment block 72 can be flexibly adjusted according to the structure of different decorative aluminum panels, ensuring that the support force always acts on the stress position of the decorative aluminum panel, and further improving the adaptability of the welding device to outdoor decorative aluminum panels of different specifications and structures.

[0063] In an optional example, please refer to Figures 1 to 11 As shown, the contact end 721 has a side wall groove 722 extending toward the center of the outdoor decorative aluminum plate, so that there is a flow gap between the side wall groove 722 and the outdoor decorative aluminum plate, and the outlet of the cooling air duct 701 is located in the side wall groove 722.

[0064] Specifically, in this example, the cooling air duct 701 integrated inside the side support component 7, together with the side wall groove 722 structure on the contact end 721, allows the cooling airflow to be buffered, evenly distributed, and guided within the groove, and then uniformly distributed to the welding heat-affected zone of the inner wall of the aluminum plate through the flow gap. This avoids the problem of secondary thermal stress concentration caused by excessive airflow impact and sudden local temperature drop in the direct-blowing cooling method, achieving a gentle and uniform conformal cooling effect. It can quickly remove welding heat and reduce the heat input and residual stress of the decorative aluminum plate.

[0065] In an optional example, please refer to Figures 1 to 11As shown, the end of the side rotating shaft 75 has a bottom hole 751 along the axial direction. Several side wall through holes 752 communicating with the bottom hole 751 are formed on the outer wall of the side rotating shaft 75. The rotating bracket 71 has a first rotating hole 711 and a second rotating hole 712. The side rotating shaft 75 is inserted into the first rotating hole 711 by a key connection. A first venting ring groove 713 is formed in the first rotating hole 711, communicating with the side wall through holes 752. A second venting ring groove 714 is formed in the first rotating hole 711. A bracket flow channel 715 is formed in the rotating bracket 71, and the bracket flow channel 715 communicates with the first venting ring groove 712. The groove 713 and the second ventilation ring groove 714 are connected. The lower end of the contact block 72 is provided with a downwardly extending contact shaft 723. The contact shaft 723 is inserted into the second rotating hole 712 by rotation. The contact block 72 is provided with a contact flow channel 724. One end of the contact flow channel 724 passes through the outer wall of the contact shaft 723 and is connected to the second ventilation ring groove 714. The other end of the contact flow channel 724 passes through the side wall groove 722. The bottom hole 751, the side wall through hole 752, the support flow channel 715, the first ventilation ring groove 713, the second ventilation ring groove 714 and the contact flow channel 724 are connected and combined to form a cooling air duct 701. The external compressed cold air enters the bottom hole 751 through the air inlet at the bottom of the side shaft 75, and flows through the side wall through hole 752, the first ventilation ring groove 713, the support flow channel 715, the second ventilation ring groove 714 and the contact flow channel 724 in sequence. Finally, it is blown out evenly from the air outlet in the side wall groove 722 of the contact end 721. Under the guidance and flow equalization of the side wall groove 722, the cooling airflow is evenly diffused to the inner wall of the welding heat-affected zone of the aluminum plate through the flow gap.

[0066] Specifically, this example integrates the entire cooling air duct 701 into the interior of the rotating component through the cooperation of the bottom hole 751, the side wall through hole 752, the bracket flow channel 715, the first ventilation ring groove 713, the second ventilation ring groove 714 and the contact flow channel 724. This allows the cooling gas to still be stably transmitted to the air outlet of the contact block 72 through the annular channel during the rotation of the side shaft 75 driving the rotating bracket 71. This eliminates the need for external cooling pipes, reduces the risk of pipe interference and damage, and improves the reliability and service life of the cooling system.

[0067] In an optional example, please refer to Figures 1 to 12 As shown, the outer wall of the contact shaft 723 is provided with several positioning slots 725. An elastic positioning piece 726 is fixed on the rotating bracket 71. An elastic contact head 727 is provided on the elastic positioning piece 726. The elastic contact head 727 can be inserted into the positioning slot 725 and restricts the rotation of the contact shaft 723 by its own elasticity. Among them, an extension flange is provided on the second rotating hole 712, and the elastic positioning piece 726 is snapped and fixed in the extension flange.

[0068] Specifically, this example achieves multi-angle rotation limiting function of the contact block 72 relative to the rotating bracket 71 by opening a positioning slot 725 on the contact shaft 723 and cooperating with the elastic positioning piece 726 and elastic contact head 727 fixed on the rotating bracket 71. During the process of the contact block 72 contacting the inner wall of the aluminum plate, the contact shaft 723 can adaptively rotate slightly according to the slight tilt, curvature change or folding angle of the aluminum plate surface, overcoming the elastic force of the elastic positioning piece 726, so that the contact end 721 and the inner wall of the aluminum plate achieve the best surface contact fit state. After the fit is completed, the elastic contact head 727 automatically locks into the corresponding positioning slot 725 under its own elastic force, reliably locking the contact block 72 and preventing the contact block 72 from loosening or shifting due to welding vibration. It can realize the dual functions of passive adaptive adjustment and active locking. The structure is simple and reliable, and improves the adaptability and support stability of the side support component 7 to different aluminum plate inner wall shapes.

[0069] In an optional example, please refer to Figures 1 to 14 As shown, a central support assembly 8 is fixed on the rotating frame 101, and the central support assembly 8 has a central support end 801 that is capable of moving with multiple degrees of freedom. The central support end 801 can abut against the middle part of the decorative aluminum plate and support the middle part of the decorative aluminum plate.

[0070] Specifically, in this example, the middle support end 801 can be precisely adjusted with multiple degrees of freedom in the horizontal plane and vertical plane, so that the middle support end 801 can be flexibly adjusted to the optimal support point and support height according to the size, shape and bottom contour of different aluminum plates, realizing rapid matching and precise alignment of the bottom support position, and further improving the adaptability of the welding device to decorative aluminum plates of various specifications and shapes.

[0071] In an optional example, please refer to Figures 1 to 14As shown, the central support assembly 8 includes a first bracket 81 fixedly connected to the rotating frame 101 by bolts. A guide slide rod 82 is provided on the first bracket 81 along the width direction of the rotating frame 101. A guide sleeve 83 is slidably fitted onto the outer wall of the guide slide rod 82. A sleeve bolt 84 is threaded onto the guide sleeve 83. The end of the sleeve bolt 84 abuts against the outer wall of the guide slide rod 82, fixing the relative position of the guide sleeve 83. The guide sleeve 83 is bolted... A second bracket 85 is fixed in place. A third bracket 86 is vertically mounted on the second bracket 85 via a sliding mechanism. An adjusting screw 87 is mounted on the lower end of the third bracket 86 via a bearing connection. An adjusting through hole is formed in the second bracket 85, through which the adjusting screw 87 passes. A locking nut 88 is threaded onto the outer wall of the adjusting screw 87, abutting against the second bracket 85. A central support end 801 is located at the upper end of the third bracket 86. An annular sliding sleeve is bolted to the second bracket 85, and a cylindrical guide rod is bolted to the lower end of the third bracket 86, the cylindrical guide rod slidingly inserted into the annular sliding sleeve.

[0072] Specifically, in this example, the operator can push the second bracket 85 along the guide slide rod 82 according to the width of the aluminum plate, so that the middle support end 801 moves to the corresponding position in the center area of ​​the bottom of the aluminum plate in the width direction of the rotating frame 101. Then, rotate the sliding sleeve bolt 84 so that the end of the sliding sleeve bolt 84 abuts against the outer wall of the guide slide rod 82 and fixes the relative position of the guide sleeve 83. Next, rotate the adjusting screw 87 to drive the third bracket 86 to move vertically upward, so that the flexible buffer pad on the upper end of the middle support end 801 flexibly contacts the center area of ​​the bottom of the aluminum plate, providing vertical auxiliary support force for the aluminum plate. After adjustment, tighten the locking nut 88 so that the upper end of the locking nut 88 abuts tightly against the lower end of the second bracket 85, thereby locking the vertical position of the third bracket 86 and ensuring the positional accuracy of the middle support end 801.

[0073] In an optional example, please refer to Figures 1 to 14 As shown, a negative pressure module 9 is fixed on the third bracket 86. The negative pressure module 9 has a negative pressure end 91 that is at the same horizontal height as the middle support end 801 and is used to fix the outdoor decorative aluminum panel. The negative pressure module 9 can be a negative pressure suction cup.

[0074] Specifically, in this example, the negative pressure end 91 and the middle support end 801 are at the same horizontal height, and the upper surface of the middle support end 801 is provided with a flexible buffer pad. While the aluminum plate is fixed by negative pressure adsorption, the flexible buffer provides elastic support at the bottom of the aluminum plate, avoiding the indentation or scratches that may be caused to the surface of the aluminum plate by rigid contact.

[0075] In summary, this invention achieves rapid clamping of decorative aluminum panels through the cooperation of welding module 2, first clamping platform 3, second clamping platform 4, clamping telescopic cylinder 5, positioning block 6, and side support assembly 7. It applies uniform vertical clamping force to the decorative aluminum panels from above, preventing movement and warping of the aluminum panels during welding. This ensures strict control over the precision of the joint gaps between the decorative aluminum panel raw materials, improving weld formation quality and welding efficiency. Simultaneously, the side support assembly 7, integrated into the clamping platform, provides stable lateral support from the inside of the decoration, enhancing the structural rigidity of the aluminum panels during high-temperature welding and resisting dents or wave deformations caused by thermal stress. Furthermore, the side support assembly 7 internally integrates… The cooling air duct 701 can accurately deliver cold air to the inner wall of the welding heat-affected zone, achieving a conformal cooling effect of welding and cooling simultaneously. This reduces the heat input and residual stress of the aluminum plate, and avoids welding deformation of large outdoor thin-walled aluminum plates. Finally, by opening side grooves 301 along the length direction on the first clamping table 3 and the second clamping table 4, the side support assembly 7 can be adjusted in position along the length direction of the rotating frame 101. This allows for flexible adjustment of the support points of the contact block 72 according to the structure of different decorative aluminum plates, ensuring that the support force always acts on the stress position of the decorative aluminum plate. This further enhances the adaptability of the welding device to outdoor decorative aluminum plates of different specifications and structures.
