Description

Technical Field

[0001] This invention relates to the field of welding equipment, and more particularly to a welding device and method for the construction of a chemical energy storage tank. Background Technology

[0002] Welding is an indispensable core process in the construction of chemical energy storage tanks, directly affecting the structural safety, long-term sealing performance, and overall service life of the tank. As a sealed container holding electrolyte or energy storage medium, the energy storage tank's frame and outer cladding plates must be welded together to form a high-strength integral structure to withstand internal pressure, transportation loads, and environmental stresses. In particular, the welding of the plates requires not only ensuring continuous, leak-free welds for excellent airtightness and corrosion resistance, but also that the welding quality and deformation control directly impact the accuracy and efficiency of subsequent modular assembly. Therefore, extremely high demands are placed on the reliability, consistency, and automation level of the welding process.

[0003] However, existing welding technologies have significant shortcomings when applied to the construction of chemical energy storage tanks. Traditional manual or semi-automatic welding methods heavily rely on welder skills, making it difficult to ensure dimensional consistency and uniform weld quality in the splicing of large frames and plates, easily leading to defects such as deformation, misalignment, or incomplete penetration. Furthermore, existing equipment lacks dedicated positioning and flexible clamping systems for energy storage tank frame structures (such as multiple horizontal and vertical frame strips), resulting in low assembly efficiency and difficulty in controlling precision. During welding, the workpiece is typically fixed, and the welding torch has a limited range of movement, making it difficult to achieve continuous, high-quality welding around the tank from all angles (especially in overhead welding positions). Moreover, the lack of real-time fume treatment and deformation suppression measures linked to the welding action affects the construction environment and the reliability of the final product. Summary of the Invention

[0004] To address the problems existing in the background technology, a welding device and method for the construction of a chemical energy storage tank are proposed. Through the coordination of the moving frame and the horizontal / vertical welding positioning components, the precise adjustment and assembly of the frame size are realized. By combining the multi-degree-of-freedom movement of the welding components and the rotation and flipping of the welding frame, a one-time, high-quality, all-round sealing welding of the energy storage tank frame and cladding plates is completed.

[0005] This invention proposes a welding device for the construction of a chemical energy storage chamber, including a welding table, a welding frame, a movable frame, and a welding assembly. The welding table has a welding channel at its center and a plate inlet connected to the welding channel at its front. The welding frame includes a rotating disk rotatably mounted on the welding channel and having a notch (notch 1); a rotating frame with a second notch is rotatably mounted on the first notch; the opening directions of the first and second notches are the same, but their rotation directions are staggered, and both notches 1 and 2 are synchronously connected to or staggered with the plate inlet through rotation. Multiple sets of movable frames are slidably mounted on the second notch, corresponding one-to-one with the horizontal frame bars and horizontally coordinated. A horizontal welding positioning component is slidably mounted in the middle of each set of movable frames, and vertical welding positioning components are slidably mounted on both sides. The positioning ends of the multiple sets of horizontal welding positioning components face the same direction for matching the horizontal frame bars; the positioning ends of the two vertical welding positioning components face opposite directions for matching the vertical frame bars and the cladding plate. The welding assembly is located on the welding table and moves along the welding channel in an arc-shaped trajectory, simultaneously welding the horizontal and vertical frame bars and the cladding plate from the outer periphery through the movement, lifting, and rotation of the welding ends.

[0006] Preferably, the welding table includes a base with a welding channel; a guide frame is provided around the welding channel at the upper end of the base, and a support platform is provided at the lower end; the base is also provided with a drive structure for driving the rotating disk to rotate along the origin of the horizontal plane; the guide frame is provided with an arc-shaped track for the welding components to move in an arc-shaped trajectory; the support platform is slidably connected to the rotating disk.

[0007] Preferably, a smoke removal trough is provided on the guide frame in front of the arc-shaped track; the opening of the smoke removal trough is equipped with a slag-blocking net and is connected to the negative pressure smoke removal equipment through a pipe; the smoke removal trough is set as an arc-shaped structure coaxial with the arc-shaped track and is divided into multiple independently working smoke removal chambers by partitions, while the arc-shaped track is provided with a positioning activation sensor that matches the position of the smoke removal chamber.

[0008] Preferably, the welding assembly includes an electric slider that slides along an arc-shaped track; a movable seat that slides along the radius of the arc-shaped track is provided on the electric slider; a telescopic table is provided on the movable seat; a rotary table is provided on the telescopic end of the telescopic table; a telescopic frame is provided on the side wall of the rotary table; and a welding device that can swing back and forth is provided at the end of the telescopic frame.

[0009] Preferably, a second driving structure is provided on the rear wall of the notch of the rotating disk; the rotating frame is driven by the second driving structure to rotate at the origin along the vertical plane on the rotating frame.

[0010] Preferably, the rotating frame is a horizontally placed U-shaped structure with the opening facing forward, and guide rails are provided on the horizontal sections on both sides for the moving frame to move back and forth; guide rails are provided on the moving frame for the horizontal welding positioning parts and the vertical welding positioning parts to move left and right.

[0011] Preferably, the transverse welding positioning component includes a positioning frame 1; the positioning frame 1 has a U-shaped structure, with an electric slider 2 that moves along a guide rail 2 at the bottom, and an installation port 1 on the side wall; the positioning ends of multiple sets of transverse welding positioning components are set inside the U-shaped structure, and the openings of the positioning ends face the same direction; multiple sets of telescopic strips 1 are set at the bottom of the U-shaped structure of the positioning frame 1; two sets of telescopic platforms 1, one on the left and one on the right, are respectively set on the installation ports 1 on both sides, and electric wheels 1 are set on the opposite ends.

[0012] Preferably, a negative pressure adsorption area is provided on the U-shaped structure opening side of the positioning frame.

[0013] Preferably, the vertical welding positioning component includes a positioning frame two; the positioning frame two has a U-shaped structure, with an electric slider three that moves along the guide rail two at the bottom, and an installation port two on the side wall; the positioning ends of multiple positioning frames two are set inside the U-shaped structure, and the openings of the positioning ends on both sides face each other; multiple sets of telescopic strips two are respectively set at the top and bottom of the U-shaped structure of the positioning frame two; two sets of telescopic platforms two, one above the other, are both set on the installation port two, and electric wheels two are set on the side facing the opening of the positioning end.

[0014] This invention further proposes a welding method for the construction of a chemical energy storage chamber, employing the aforementioned welding device for chemical energy storage chamber construction. The steps are as follows: First, rotate the welding frame so that the moving frame is horizontal and the positioning end of the horizontal welding positioning component faces upward; fix the horizontal frame strip to the horizontal welding positioning component, and fix the vertical frame strip to the vertical welding positioning component; then, adjust the position of individual horizontal and vertical frame strips by moving the horizontal welding positioning component and the horizontal welding positioning component; and splice the adjusted horizontal and vertical frame strips by moving the moving frame; the welding assembly moves along an arc trajectory and the welding end... The movement, lifting, and rotation of the welding assembly, combined with the rotation of the welding frame, are used to weld the spliced ​​horizontal and vertical frame strips from the outer periphery. Then, the welding frame is rotated so that notch one and notch two face forward to the inlet of the connecting plate, and the cladding plate is fed from the plate inlet into notch two, and positioned above the welded frame by the vertical welding positioning component. The rotating frame is flipped so that the cladding plate moves from above the frame to below the frame. The welding assembly moves in an arc trajectory and the welding end moves, lifts, and rotates, combined with the rotation of the welding frame, to weld the frame and cladding plate from the outer periphery.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: The core of this invention lies in the coordinated positioning of the movable frame, the transverse welding positioning components, and the vertical welding positioning components. Multiple movable frames can slide independently along guide rails, flexibly adjusting the longitudinal spacing of the frame. For each movable frame, the transverse welding positioning components control the extension length of the horizontal frame bars, while the vertical welding positioning components on both sides ensure precise alignment between the ends of the vertical and horizontal frame bars. This "fixed distance for the movable frame, fixed length for the positioning components" adjustment mechanism allows a single device to quickly adapt to the prefabrication of frames for energy storage modules of different specifications, laying a precise assembly foundation for subsequent high-quality welding. This is a necessary prerequisite for ensuring seamless assembly of large-scale prefabricated modular cabins. A dynamic coordination mechanism was established between the multi-degree-of-freedom movement of the welding components and the orientation adjustment of the welding frame. During frame welding, the welding components move along an arc-shaped track, with the telescopic table, rotary table, telescopic frame, and oscillating welding device working together to ensure the welding torch is always in the optimal welding posture. Simultaneously, the intermittent rotation of the rotating disk on the horizontal plane sequentially "feeds" the four edges of the frame into the welding torch's working area, achieving continuous and uniform outer perimeter fillet welds. When welding the cladding plates, the 180-degree rotation of the rotating frame is crucial, flipping the workpiece from plate-on-top to plate-on-bottom, placing the lap joint in the easiest position for welding. Combined with the oscillating welding function of the welding components, a full and sealed weld can be formed. This combination strategy of "welding torch repositioning + workpiece rotation" effectively solves the challenges of overhead and vertical welding of all external joints in large-size enclosures, and is the core guarantee for achieving airtight and watertight welding quality in the energy storage compartment. The invention features automated and centralized control of the entire process from positioning, welding, flipping to unloading, with all components operating in a coordinated manner. For example, during welding, the corresponding chamber of the fume extraction trough automatically activates fume extraction, while the negative pressure adsorption area on the horizontal welding positioning component locally cools and fixes the workpiece, collectively suppressing thermal deformation. The upper and lower telescopic strips and telescopic platform of the vertical welding positioning component not only fix the vertical frame strips but also serve as conveyor rollers and clamps for the frame plate after retracting upwards, offering multiple uses and reducing process changeover time. This highly collaborative automated process integrates the previously fragmented operations relying on multiple welders, multiple machines, and multiple hoisting and positioning operations into a continuous assembly line operation. This not only multiplies efficiency and avoids quality fluctuations caused by human factors but also significantly reduces the labor intensity and fume exposure risk for welders. For engineering projects like chemical energy storage tanks that require batch, rapid, and high-quality construction, this has significant engineering practical value. Attached Figure Description

[0017] Example 1: This invention proposes a welding device for the construction of a chemical energy storage chamber, such as... Figures 1-3As shown, the assembly includes a welding table 1, a welding frame, a moving frame 5, and a welding component 2. The welding table 1 has a welding channel at its center and a plate inlet connected to the welding channel at its front. The welding frame includes a rotating disk 3 rotatably mounted on the welding channel and having a notch 1; a rotating frame 4 with a notch 2 rotatably mounted on the notch 1; the opening directions of notches 1 and 2 are the same, but their rotation directions are staggered, and both notches 1 and 2 are synchronously connected to or staggered with the plate inlet through rotation. Multiple sets of moving frames 5 are slidably mounted on the notches 2, corresponding one-to-one with the horizontal frame bars and horizontally coordinated. A horizontal welding positioning component 6 is slidably mounted in the middle of each set of moving frames 5, and vertical welding positioning components 7 are slidably mounted on both sides. The positioning ends of the multiple sets of horizontal welding positioning components 6 face the same direction to match the horizontal frame bars; the positioning ends of the vertical welding positioning components 7 face opposite directions to match the vertical frame bars and the cladding plate. The welding component 2 is located on the welding table 1 and moves along the welding channel in an arc-shaped trajectory, simultaneously welding the horizontal frame bars, vertical frame bars, and cladding plate from the outer periphery through the movement, lifting, and rotation of the welding ends.

[0018] like Figure 4 As shown, the welding table 1 includes a base 101 with a welding channel; a guide frame 102 is provided around the welding channel at the upper end of the base 101, and a support platform 105 is provided at the lower end. The base 101 is also provided with a drive structure 9 that drives the rotating disk 3 to rotate along the origin of the horizontal plane; an arc track 103 is provided on the guide frame 102 for the welding assembly 2 to move in an arc trajectory; the support platform 105 is slidably connected to the rotating disk 3.

[0019] It should be further explained that the drive structure 9 includes a drive wheel that is driven to rotate by a motor; the side wall of the rotating disk 3 is provided with a drive groove 301 that matches the drive wheel.

[0020] Driven by the drive structure 9, the rotating disk 3 rotates at its origin within the welding slot, adjusting the position of the frame and the cladding plate. Simultaneously, the welding assembly 2 moves along the arc-shaped track 103, further increasing the flexibility of welding and achieving comprehensive and efficient welding.

[0021] It should be further explained that a smoke removal trough 104 is provided on the guide frame 102 in front of the arc-shaped track 103; the opening of the smoke removal trough 104 is equipped with a slag-blocking net and is connected to the negative pressure smoke removal equipment 8 through a pipe; the smoke removal trough 104 is set as an arc-shaped structure coaxial with the arc-shaped track 103, and is divided into multiple independently working smoke removal chambers by a partition. At the same time, the arc-shaped track 103 is provided with a positioning activation sensor that matches the position of the smoke removal chamber.

[0022] During the welding process, the welding assembly 2 moves along the arc track 103 to perform welding. The position is sensed by the position activation sensor, and a negative pressure is formed at the corresponding smoke removal chamber to collect the welding fumes generated at that location, effectively reducing air pollution.

[0023] like Figure 5 As shown, the welding assembly 2 includes an electric slider 201 that slides along an arc-shaped track 103; a movable seat 202 that slides along the radius of the arc-shaped track 103 is provided on the electric slider 201; an electrically controlled telescopic table 203 is provided on the movable seat 202; a rotary table 204 that is driven to rotate by a motor is provided on the telescopic end of the telescopic table 203; an electrically controlled telescopic frame 205 is provided on the side wall of the rotary table 204; and a welding device 206 that is driven by a motor and can swing back and forth is provided at the end of the telescopic frame 205.

[0024] Through the coordination and linkage of the above-mentioned structures, the welder 206 can move back and forth, swing, rise and fall, and rotate while moving along an arc trajectory. This ensures that the welding angle and position meet the welding requirements of the chemical energy storage tank's plates.

[0025] like Figures 6-7 As shown, a second driving structure is provided on the rear wall of the notch of the rotating disk 3; the rotating frame 4 is driven by the second driving structure to rotate at the origin along the vertical plane on the rotating frame 4.

[0026] It should be further explained that the second drive structure is a rotary motor.

[0027] By rotating the rotating disk 3 horizontally and the rotating frame 4 vertically, the flexibility of adjusting the position and angle of the material to be welded is increased.

[0028] It should be further explained that the rotating frame 4 is a horizontally placed U-shaped structure with the opening facing forward. Guide rails 401 are provided on the horizontal sections on both sides for the moving frame 5 to move back and forth. Guide rails 501 are provided on the moving frame 5 for the horizontal welding positioning parts 6 and the vertical welding positioning parts 7 to move left and right.

[0029] Since the horizontal frame bars correspond one-to-one with the movable frame 5 and are horizontally aligned, the spacing between adjacent horizontal frame bars can be adjusted by sliding multiple sets of movable frames 5 back and forth on guide rail 401 to meet the size requirements of the chemical energy storage tank construction panels. The positioning positions and the positions of individual horizontal and vertical frame bars can be adjusted by moving the horizontal welding positioning parts 6 and vertical welding positioning parts 7 left and right on guide rail 501, making the frame splicing precise, automatic, and efficient, thus meeting the welding precision requirements of the chemical energy storage tank construction panels.

[0030] like Figures 8-9As shown, the transverse welding positioning component 6 includes a positioning frame 601; the positioning frame 601 has a U-shaped structure, with an electric slider 604 that moves along the guide rail 501 at the bottom, and an installation port 1 on the side wall; the positioning ends of multiple sets of transverse welding positioning components 6 are set inside the U-shaped structure, and the openings of the positioning ends face the same direction; multiple sets of electrically controlled telescopic bars 603 are set at the bottom of the U-shaped structure of the positioning frame 601; two sets of electrically controlled telescopic platforms 602, one on the left and one on the right, are respectively set on the installation ports 1 on both sides, and electric wheels 1 are set on the opposite ends.

[0031] The horizontal frame strip is placed between two sets of telescopic platforms 602. Telescopic bars 603 and electric wheels are positioned close to the horizontal frame strip. The telescopic bars 603 adjust the height of the horizontal frame strip, allowing it to be pushed to fit against the cladding material. The electric wheels clamp the horizontal frame strip and can be used to move it.

[0032] It should be further explained that a negative pressure adsorption area 605 is provided on the U-shaped structure opening side of the positioning frame 601; this area can remove smoke during welding, and can also adsorb, fix, cool and shape the plate area near the horizontal frame strip after the frame plate is fed in.

[0033] like Figure 10 As shown, the vertical welding positioning component 7 includes a positioning frame 2 701; the positioning frame 2 701 has a U-shaped structure, with an electric slider 3 704 that moves along the guide rail 2 501 at the bottom, and an installation port 2 on the side wall; the positioning ends of multiple sets of positioning frames 2 701 are set inside the U-shaped structure, and the openings of the positioning ends on both sides face each other; multiple sets of electrically controlled telescopic bars 2 703 are respectively set at the top and bottom of the U-shaped structure of the positioning frame 2 701; two sets of electrically controlled telescopic platforms 2 702, one above the other, are both set on the installation port 2, and electric wheels 2 are set on the side facing the opening of the positioning end.

[0034] The vertical frame strip is placed between the upper and lower telescopic strips 703, with the telescopic strips 703 and the electric wheels 703 positioned close to the vertical frame strip. After the frame welding is completed, the upper telescopic strip 703 retracts, leaving space between it and the vertical frame strip for the cladding panel to enter. The cladding panel is fed into notch 2 from the panel inlet and then pushed into the upper frame by the upper electric wheels 703, where its position is adjusted. Then, the upper telescopic strip 703 descends and locks in place, ensuring it fits snugly against the frame.

[0035] Therefore, the extension and retraction of the lower telescopic strip 703 can adjust the height of the vertical frame strip, allowing it to be pushed to fit against the cladding panel. The extension and retraction of the upper telescopic strip 703 can fix the cladding panel. The upper and lower telescopic strips 703 can also work simultaneously, fixing the vertical frame strip separately during the initial welding and fixing the frame and cladding panel during the secondary welding. The lower row of electric wheels 703 can provide auxiliary clamping from one side, allowing the vertical frame strip to move. The upper row of electric wheels 703 can also clamp the cladding panel from one side, allowing the cladding panel to move.

[0036] Example 2, as Figures 1-3 and with Figure 11 As shown, this embodiment proposes a welding method for the construction of a chemical energy storage chamber, using the welding device for the construction of a chemical energy storage chamber described in Embodiment 1. The steps are as follows: S1. Frame Prefabrication and Precise Positioning Stage First, position the movable frame 5 horizontally with the positioning ends of the transversely welded positioning parts 6 facing upwards. At this time, multiple sets of movable frames 5 are in their initial positions on the guide rail 401, for example, with a preset spacing of 1.2 meters for the standard energy storage module. The operator places multiple horizontal frame strips into the transversely welded positioning parts 6 on the corresponding movable frames 5. Specifically: The horizontal frame is placed between two sets of telescopic platforms 602. After activation, the telescopic platforms 602 move towards each other, and the electric wheels at their ends clamp the two sides of the frame. At the same time, the telescopic strip 603 at the bottom rises, lifting the horizontal frame to a preset height, such as 50mm from the positioning reference surface. Similarly, the vertical frame is placed into the vertically welded positioning parts 7 on both sides and clamped and fixed by the telescopic strips 703 at the top and bottom. The lower telescopic platform 702 and its electric wheels 703 assist in clamping from the inside. Subsequently, the automatic adjustment stage begins. Based on the input frame design dimensions (e.g., 3000mm long, 1200mm wide), the control system plans the path. The two movable frames 5 slide backward synchronously along guide rail 401, moving the vertical frame bars on them to a position 600mm from the center line. All transverse welded positioning components 6 move laterally on guide rail 501 via their bottom electric sliders 604, adjusting the transverse frame bars to the designed length endpoints. The vertical welding positioning component 7 moves synchronously with its electric slider 704, precisely aligning the ends of the vertical and horizontal frame bars to form a "well" shaped frame. Positioning accuracy is controlled by a servo motor, and the repeatability error can be controlled within ±0.1mm. S12, Automated Welding Stage of Frame Periphery After the frame assembly is completed, the welding procedure is initiated. Welding component 2 begins collaborative operation; the electric slider 201 moves along the arc track 103 to the welding starting point, such as the middle of one side of the frame. The moving seat 202 slides radially, positioning the tip of the welding torch 206 at the optimal arc-starting position approximately 5mm from the weld seam. The telescopic table 203 is fine-tuned according to the frame height, such as 50mm, to ensure that the welding torch maintains a constant angle with the workpiece, typically 70-80 degrees. The rotary table 204 adjusts the circumferential angle of the welding torch, and the telescopic frame 205 extends and retracts to compensate for changes in path curvature. Welding begins, and the electric slider 201 moves along the arc-shaped track 103 at a constant speed, such as 200 mm / min. The system synchronously controls the rotating disk 3 to rotate intermittently from its origin; for example, after each side is welded, it rotates 90 degrees, ensuring each side of the frame enters the optimal welding position sequentially. During welding, when the welding torch moves to a corner of the frame, the rotary table 204 coordinates with the rotation of the rotating disk 3, allowing the welding torch to smoothly transition to the adjacent side, achieving continuous, dead-angle-free outer perimeter fillet weld welding. At the same time, the fume extraction chamber corresponding to the welding torch position in the fume extraction trough 104 is activated, and the fume extraction chamber efficiently extracts dust through a negative pressure of -500Pa to -800Pa, achieving a purification rate of over 95%. Simultaneously, the negative pressure adsorption area 605 located on the opening side of the U-shaped structure of the transverse welding positioning component 6 also operates, adsorbing the area near the fixing frame strip to reduce welding thermal deformation. S3, Positioning and Secondary Welding of Frame Panels After the frame welding is completed and cooled, the frame-wrapping process is carried out. The control system drives the rotating disk 3 to rotate, so that notch one is aligned with the plate inlet. At the same time, it drives the rotating frame 4 to rotate at its origin in the vertical plane, so that notch two also faces forward and connects with notch one, forming a plate conveying channel. The operator or automatic feeder pushes the frame-wrapping plate, which is slightly larger than the frame outline, into the plate inlet along the channel and into the area of ​​the rotating frame 4. At this time, the telescopic bar 703 above the vertical welding positioning piece 7 is in the retracted state, and the upper telescopic platform 702 and its electric wheel 2 start, pressing the plate from above and driving it forward until the plate completely covers the upper surface of the frame and exceeds the set edge distance, such as 15mm on each side. Then, the upper telescopic bar 703 descends, pressing the plate tightly against the upper surface of the completed frame. At the same time, all the telescopic bars 603 and 703 can be finely adjusted and raised below to ensure that the lower surface of the frame is tightly fitted with the plate and eliminate gaps. Next, the frame welding is performed. Drive structure two rotates the rotating frame 4 and its pre-positioned "frame-plate" assembly by 180 degrees, moving the plate below the frame; the process similar to the frame perimeter welding is repeated; welding assembly 2 moves again along the arc track 103, with rotating disk 3 cooperating in the rotation. The focus of this welding is to perform lap fillet welds or rolled edge welds between the plate edge and the frame perimeter. The oscillation function of the welder 206 is particularly crucial at this stage, allowing for small oscillations such as 2-4mm amplitude and 2Hz frequency to widen the weld bead, ensuring a full and sealed weld between the plate and the frame, meeting the sealing requirements of the chemical energy storage chamber; during welding, the horizontal welding positioning component 6 and the vertical welding positioning component 7 continue to perform multi-point, multi-directional positioning to reduce deformation and displacement during welding; S4. Material feeding and resetting stage After all welding is completed, all positioning and clamping mechanisms are released, and workers remove the welded chemical energy storage chamber construction plates. All moving parts, such as the moving frame 5, various positioning components, and welding assembly 2, automatically return to their initial positions, ready for the next work cycle.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
