Description

Technical Field

[0001] The present invention relates to the technical field related to welding, and in particular to an automatic welding device for a box-type substation shell. Background Art

[0002] A box-type substation, also known as a prefabricated substation or modular substation, is a highly integrated power system that integrates core functional modules such as high-voltage distribution, transformers, and low-voltage distribution within one or more sealed metal or non-metallic boxes to receive, transform, and distribute electrical energy. It functions as a small "power hub" and is widely used in urban, rural, and industrial areas.

[0003] In a substation, the casing serves as the main supporting component of the cabinet, and welding is usually used to fix multiple panels to each other.

[0004] After searching, a distribution cabinet welding device with publication number CN216398592U and a distribution cabinet welding device with publication number CN118357725B were disclosed, including but not limited to these two patents. Both of them use the method of clamping and fixing four plates and then welding the joints.

[0005] This type of welding equipment requires clamping / limiting work, which takes a relatively long time, resulting in a disproportionate welding and clamping time. For example, if it takes five minutes to weld a frame, then it will also take five minutes to lift and clamp the plate, or even longer, resulting in low welding efficiency.

[0006] Secondly, this type of welding equipment cannot complete the welding work automatically and still requires manual assistance. It is well known that welding is a high-risk industry with high temperatures, harmful gases, strong light radiation, etc. High temperatures may cause burns, ultraviolet rays generated by the arc may cause photoelectric eye inflammation, and metal particles in the smoke may cause lung diseases.

[0038] (1) The automatic welding device for the box-type substation shell can limit the shell plate through the support formed by the limit plate and the box body. The advantages of this relative clamping method are as follows:

[0039] 1. The structure is simple, the operation time required for limiting is short, and the preparation time required for welding is reduced;

[0040] Second, by utilizing the characteristics of the shell plates, the right-angled butt joints between the plates usually require a 45° inclined surface to be cut on one side to ensure butt joint during welding.

[0042] (2) The automatic welding device for the box-type substation shell realizes the automatic placement of the shell plate to the designated position through the cooperation of the translation mechanism and the plate placement mechanism. It has flexible movement and a mature and simple structure.

[0043] (3) The automatic welding device for the box-type substation shell uses a lifting component to lift the frame after welding is completed, so that the frame can be taken out by the grasping structure.

[0044] (4) The automatic welding device for the shell of the box-type substation realizes the welding work of the shell plates that have completed the butt-jointing and limiting by means of the welding mechanism, and there is no need to change the position of the shell plates after the splicing and limiting.

[0045] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0065] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0066] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0067] The following is based on Figures 1-18 The present invention describes an automatic welding device for a box-type substation shell provided by an embodiment of the present invention.

[0068] See also Figures 1-18 An embodiment of the present invention provides a technical solution: an automatic welding device for a box-type substation shell, comprising a rectangular box body 301, wherein the box body 301 has four flat corners, each of which has a notch 309, and a welding mechanism is installed in the box body 301 and the notch 309.

[0069] Among them, the box body 301 has two Y-axis surfaces and two Z-axis surfaces, the two Y-axis surfaces are parallel to each other, and the two Z-axis surfaces are parallel to each other. The Y-axis surface is the length surface of the box body 301, and the Z-axis surface is the width surface of the box body 301. The Z-axis surface and the Y-axis surface of the box body 301 are both fixed with a limit plate 3, and the limit plate 3 and the connection part between the limit plate 3 and the box body 301 form a support part. The support part of the Y-axis surface is lower than the support part of the Z-axis surface, and a supporting part is installed in the Y-axis surface support part, and a lifting component is installed at the bottom of the supporting part.

[0070] See also Figures 8-11 The above-mentioned support portion refers to the portion between the limit plate 3 and the box body 301. This portion is a plate body used to fix the limit plate 3 and the box body 301. This plate body is the support portion. When the shell plate 4 enters between the limit plate 3 and the box body 301, when the shell plate 4 falls to the end of the stroke, it is located on the support portion and supports the shell plate 4 through the support portion.

[0071] The support portion of the above-mentioned Y-axis surface is lower than the support portion of the Z-axis surface, that is, the support portion of the length surface of the box body 301 is lower than the support portion of the width surface of the box body 301. Since the support portion of the length surface of the box body 301 is installed with a supporting part and a lifting component, the shell plate 4 in the support portion of the length surface of the box body 301 is located on the supporting part after it descends to the end of the stroke and is supported by the supporting part, while the shell plate 4 in the support portion of the width surface of the box body 301 directly falls to the support portion and is supported by the support portion of the width surface of the box body 301.

[0072] Two No. 1 storage boxes 2 are arranged opposite to each other, and the two No. 1 storage boxes 2 are fixed via a No. 1 connecting plate 202.

[0073] Two No. 2 storage boxes 201 are arranged opposite each other, and the two No. 2 storage boxes 201 are fixed by a No. 2 connecting plate 203. The No. 2 connecting plate 203 and the No. 1 connecting plate 202 are placed in a cross shape and fixed to each other. A plate placing mechanism is installed on both the No. 1 storage box 2 and the No. 2 storage box 201. The No. 1 storage box 2 is fixed to the roof or frame by a translation mechanism installed on the top.

[0074] In the embodiment of the present invention, the substation shell is essentially a frame formed by welding multiple plates. Figure 12 , this application is directed to welding between four plates to form a rectangular frame.

[0075] The basic plate bodies required for welding, that is, the shell plates 4 , are placed in two No. 1 storage boxes 2 and two No. 2 storage boxes 201 respectively.

[0076] When performing welding work, the No. 1 storage box 2 and the No. 2 storage box 201 are first moved to the top of the box body 301 through the translation mechanism, and the shell plates 4 in the two No. 1 storage boxes 2 and the two No. 2 storage boxes 201 are respectively placed into the supporting parts of the Y-axis surface and the Z-axis surface through the cooperation of the translation mechanism and the plate placing mechanism. The separate placement here means that they are placed into the supporting parts of the two Y-axis surfaces and the Z-axis surface in sequence. After the placement is completed, there are four shell plates 4, and they are arranged in a rectangular shape.

[0077] Among them, the shell plate 4 on the Z-axis surface is directly supported by the support part, while the shell plate 4 on the Y-axis surface is supported by the supporting part, so that the bottoms of the four shell plates 4 are on a common plane when they fall to the end of the stroke, to ensure that there will be no unevenness during welding, and the shell plates 4 can be limited by the limiting plate 3. Through the interaction of the mating surfaces of the four shell plates 4, the four shell plates 4 will not change their positions to the left, right, front and back when they are in the support part, and the limiting of the limiting plate 3 will prevent the shell plates 4 from being deformed to a large extent when heated during welding, which will lead to the problem of large welding seams.

[0078] When the four shell plates 4 have completed the placement limit, the welding mechanism works to weld the four shell plates 4 at the same time, so that the four shell plates 4 are fixed.

[0079] Secondly, the welding mechanism of the present invention is an internal welding method, which allows the welding to be located on the inner wall of the frame. While having good aesthetics, it does not require polishing. Because its welding part is located inside the frame and at the four corners, its burrs and irregular protrusions will not affect subsequent work.

[0080] It should also be noted that the four limiting plates 3 are each provided with an arc portion 308 on the side opposite to the box body 301, which can improve the accuracy of the placement. Figure 8 .

[0081] The present invention performs splicing and limiting in this manner, so that the docking positions of the four shell plates 4 are all exposed. The welding mechanism performs welding work internally or / and externally to meet different welding requirements.

[0082] Secondly, this method is not limited to the welding of plates, but can also be used for welding square tubes, rectangular frames, etc., and has a wider range of applications.

[0083] The welding mechanism includes a stabilizing frame 303 disposed inside the box 301 and slidably connected to the inner wall of the box 301. The stabilizing frame 303 is rectangular in shape, and each of the four corners is provided with an integrally formed extension portion.

[0084] The extensions of the stabilizing frame 303 are located in the slots 309 , and welding guns 307 are fixed on the four extensions.

[0085] At least four second screw rods 306 are rotatably mounted in the box body 301 . Each of the four second screw rods 306 is sleeved with a threaded transmission member 305 that is threadably matched therewith. The threaded transmission member 305 is fixed to the stabilizing frame 303 .

[0086] A No. 2 motor 302 is fixed to the inner wall of the box 301 , and the output shaft of the No. 2 motor 302 is connected to four No. 2 screw rods 306 through a No. 2 transmission chain 304 .

[0087] In an embodiment of the present invention, when the No. 2 motor 302 is working, its output shaft synchronously drives the four No. 2 screw rods 306 to rotate through the No. 2 transmission chain 304, so that when the No. 2 screw rods 306 rotate, the threaded transmission member 305 and the stabilizing frame 303 are driven to rise / fall upright through the thread cooperation with the threaded transmission member 305, and then the welding gun 307 is driven to rise or fall through the stabilizing frame 303.

[0088] When the welding gun 307 is working, the shell plate 4 is welded, and the motion trajectory required for welding is achieved through the vertical lifting movement.

[0089] Secondly, the lifting method through thread transmission has high transmission accuracy and smooth movement, and the required driving force is small.

[0090] It should be noted that the second motor 302 in the present invention adopts a high-precision servo motor. Of course, other types of motors can also be selected under the premise of meeting the high-precision drive requirements, such as stepper motors or DC motors, etc. The present invention does not make specific limitations.

[0091] The receiving member includes a movable groove opened on the Y-axis surface of the box body 301, in which a baffle 5 is horizontally slidably installed. An electric push rod 508 is hinged in the box body 301, and the movable rod of the electric push rod 508 is rotatably connected to the baffle 5.

[0092] Among them, a bracket for sliding support of the baffle 5 is installed in the box body 301. Due to the wall thickness of the box body 301, a bracket is provided to avoid the problem of tilting when the baffle 5 slides. The sliding support means that the baffle 5 is supported by the bracket when sliding to avoid the baffle 5 hanging in the air when sliding. Figure 10 、 Figure 11 , the drag seat is the protruding portion at the bottom of the baffle 5 in the figure;

[0093] Since a lifting assembly is installed in the support portion of the width surface of the box body 301, when the shell plate 4 falls to the end of its stroke, it is directly on the lifting assembly (roller 509), and there will be a height difference with the shell plate 4 on the width surface of the box body 301. Because the roller 509 is usually made of rubber material for wear resistance, the rubber itself will deform when it is subjected to force. Therefore, when the shell plate 4 is located on the roller 509, the roller 509 will be deformed, and then a height difference will appear during splicing.

[0094] The baffle 5 of the present invention is located above the roller 509 and can support the shell plate 4 to ensure that the shell plate 4 on the width and length surfaces of the box body 301 are at the same height.

[0095] In the embodiment of the present invention, when the electric push rod 508 is working, it drives the baffle 5 to slide by extending or retracting.

[0096] The sliding movement of the baffle 5 has two effects:

[0097] Effect 1: When the baffle 5 is extended, the Y-axis surface of the box body 301 is supported to ensure that the four shell plates 4 are at the same height when they are placed on the supporting portion.

[0098] Effect 2: When the baffle 5 is retracted, the lifting assembly can work normally. After the shell plate 4 is welded, the shell plate 4 can be lifted by the lifting assembly, so that the shell plate 4 can be taken out more easily.

[0099] The function of the supporting portion is to effectively support the baffle 5 during the sliding process of retraction.

[0100] The lifting assembly includes a first transmission plate 501 and a second transmission plate 502 , and the first transmission plate 501 and the second transmission plate 502 are rotatably connected at the center.

[0101] Two threaded sliders 503 are slidably installed in the Y-axis support portion of the box body 301. One end of the No. 1 transmission plate 501 and the No. 2 transmission plate 502 is rotatably connected to the two threaded sliders 503, and the other end is rotatably installed with a roller 509.

[0102] A bidirectional screw rod 505 threadedly engaged with the two threaded sliders 503 is rotatably installed in the Y-axis support portion of the box body 301 . A transmission rod 506 is also rotatably installed in the box body 301 . The transmission rod 506 is connected to the two bidirectional screw rods 505 through a bevel gear set 504 .

[0103] In an embodiment of the present invention, a driving motor is also installed in the box body 301, and the output shaft of the driving motor is connected to the transmission rod 506 through a synchronous belt or gear, so that the transmission rod 506 is driven to rotate through the synchronous belt when the driving motor is working, and when the transmission rod 506 rotates, the two bidirectional screw rods 505 are synchronously driven to rotate through the bevel gear set 504.

[0104] When the bidirectional lead screw 505 rotates, the two threaded sliders 503 are driven to move relative / oppositely by cooperating with the threads of the two threaded sliders 503, and then the lifting effect is achieved through the No. 1 transmission plate 501 and the No. 2 transmission plate 502. After the four shell plates 4 form a frame, they can be lifted by the No. 1 transmission plate 501 and the No. 2 transmission plate 502 to facilitate removal after welding, and the friction between the No. 1 transmission plate 501 and the No. 2 transmission plate 502 and the shell plate 4 can be reduced by the roller 509.

[0105] By using this lifting method, the lifting structure occupies less space.

[0106] The translation mechanism includes a No. 3 electric slide rail 105 fixed to two No. 2 storage boxes 201, a No. 2 electric slide rail 103 is slidably mounted on the No. 3 electric slide rail 105, one of the No. 1 electric sliders 102 is slidably mounted on the No. 2 electric slide rail 103, and a support base 1 is fixed on the No. 1 electric slider 102.

[0107] An electric slide rail 101 is fixed on the roof or the frame, and another electric slider 102 is slidably mounted on the electric slide rail 101 . The electric slider 102 is fixed to the support base 1 .

[0108] In the embodiment of the present invention, for ease of description, the two No. 1 electric sliders 102 are named No. 1 block and No. 2 block respectively. No. 1 block is slidably connected to the No. 1 electric slide rail 101 , and No. 2 block is slidably connected to the No. 2 electric slide rail 103 .

[0109] When the shell plate 4 needs to be placed on the supporting part of the limit plate 3, the support seat 1 is first driven to move to the top of the box body 301 through the sliding cooperation between the No. 1 block and the No. 1 electric slide rail 101, and then the No. 1 storage box 2 and the No. 2 storage box 201 follow the support seat 1 to move to the top of the box body 301, and then the No. 2 electric slider 104 and the No. 3 electric slide rail 105 slide to realize the No. 1 storage box 2 and the No. 2 storage box 201 to move along the width direction of the box body 301, and the No. 2 block and the No. 2 electric slide rail 103 slide to realize the No. 1 storage box 2 and the No. 2 storage box 201 to move in the length direction.

[0110] Among them, the above-mentioned "sliding" is based on electric slide rails and electric sliders.

[0111] Furthermore, the No. 1 storage box 2 and the No. 2 storage box 201 can be moved onto the box body 301, or moved to other positions to be offset from the box body 301, so as to facilitate the removal of the shell plate 4 after welding.

[0112] When the No. 1 storage box 2 and the No. 2 storage box 201 move onto the box body 301 , they can move forward, backward, left, and right, and cooperate with the plate placing mechanism to place the shell plate 4 onto the supporting portion of the limiting plate 3 .

[0113] As an optional embodiment of the present invention, the same structure as above can be used to realize the movement of the box 301, which has the same effect as above and can be used in scenarios where the hoisting cannot withstand frequent movement.

[0114] The plate placing mechanism includes a push plate 2010 slidably installed in the No. 1 storage box 2 and the No. 2 storage box 201, and a No. 1 screw rod 208 is rotatably installed on both sides of the No. 1 storage box 2 and the No. 2 storage box 201. A threaded sleeve 207 that is threadedly matched with the No. 1 screw rod 208 is sleeved on the No. 1 screw rod 208, and the threaded sleeve 207 is fixed to the push plate 2010.

[0115] A No. 1 motor 205 is fixed on both sides of the No. 1 storage box 2 and the No. 2 storage box 201 , and the output shaft of the No. 1 motor 205 is connected to the No. 1 screw rod 208 through a No. 1 transmission chain 206 .

[0116] A lower plate opening 209 is opened at the bottom of the two No. 1 storage boxes 2 and the two No. 2 storage boxes 201 on the opposite side, and an additional plate opening 204 is opened at the top of the two No. 1 storage boxes 2 and the two No. 2 storage boxes 201 on the opposite side.

[0117] The inner walls of the two No. 1 storage boxes 2 on the opposite side and the inner walls of the two No. 2 storage boxes 201 on the opposite side are both provided with embedding grooves 2011 .

[0118] In an embodiment of the present invention, when the No. 1 motor 205 is working, its output shaft drives the No. 1 screw rod 208 to rotate through the No. 1 transmission chain 206. When the No. 1 screw rod 208 rotates, the threaded sleeve 207 is driven to move axially along the No. 1 screw rod 208 through the threaded cooperation with the threaded sleeve 207, and then the push plate 2010 is driven by the threaded sleeve 207 to move toward the lower plate opening 209 or the embedded groove 2011.

[0119] When the push plate 2010 moves toward the lower plate opening 209, it pushes the shell plate 4 in the No. 1 storage box 2 or the No. 2 storage box 201 to the lower plate opening 209. When the push plate 2010 moves to the end of its stroke, the shell plate 4 on the lower plate opening 209 will not fall due to the extrusion of the shell plate 4 by the push plate 2010 and the friction between the multiple shell plates 4. After the No. 1 storage box 2 or the No. 2 storage box 201 moves to the specified position, the push plate 2010 moves back and forth to eliminate the extrusion force on the shell plate 4, and then the shell plate 4 falls through the lower plate opening 209 and falls into the support part of the limit plate 3. The material discharge trajectory is shown in FIG. Figure 13 .

[0120] Among them, when adding the shell plate 4 into the No. 1 storage box 2 or the No. 2 storage box 201, the push plate 2010 is driven to move into the embedding groove 2011, and then the shell plate 4 is dropped into the No. 2 storage box 201 or the No. 1 storage box 2 through the plate adding port 204, and then the pushed shell plate 4 is pushed away from the embedding groove 2011 by the push plate 2010. By adding one shell plate 4 and pushing it once, the shell plates 4 dropped into the No. 1 storage box 2 or the No. 2 storage box 201 can be stacked in sequence.

[0121] Through the above description, the unloading process can take into account the stacking of loading materials and the control of unloading materials, and the structure is very simple and highly practical.

[0122] The width of the lower plate opening 209 is greater than that of a single shell plate 4 , and the width of the lower plate opening 209 is less than that of two shell plates 4 .

[0123] In the embodiment of the present invention, when the extrusion force on the stacked shell plates 4 disappears, only a single lower plate opening 209 can be released through the lower plate opening 209 .

[0124] The limiting plate 3 and the box body 301 are both provided with an arc portion 308 on one side thereof, and the arc portion 308 can improve the accuracy of the delivery.

[0125] The box 301 is fixed with a control device 507 , and the electric push rod 508 , the second motor 302 , and the first motor 205 are all electrically connected to the control device 507 via wires.

[0126] In the embodiment of the present invention, all components with electronic components or components that need to be driven are electrically connected to the control device 507, including but not limited to the electric push rod 508, the second motor 302, and the first motor 205.

[0127] like Figures 14-18 As shown, as an optional embodiment of the present invention: a sleeve plate 3002 is slidably installed on the bracket, a sliding plate 3003 is slidably installed inside the sleeve plate 3002, and mutually cooperating connecting parts are installed between the sleeve plate 3002 and the sliding plate 3003.

[0128] The sliding plate 3003 is rotatably connected to the electric push rod 508;

[0129] A driving rack plate 30 is fixed to one side of the sliding plate 3003, and the driving rack plate 30 cooperates with the driven gear 3001 rotatably installed in the box body 301. A transmission column 3007 is also rotatably installed in the box body 301. The transmission column 3007 is connected to the transmission rod 506 through one of the No. 2 bevel gear sets 3008, and the transmission column 3007 is also connected to the rotating shaft of the driven gear 3001 through the No. 3 bevel gear set 3009.

[0130] A travel limiting groove 3011 is provided on the bracket, and a travel limiting block 3012 fixedly connected to the sleeve plate 3002 is slidably installed in the travel limiting groove 3011 .

[0131] In an embodiment of the present invention, when the electric push rod 508 is working, the sliding plate 3003 is driven to slide on the bracket by retracting the movable rod of the electric push rod 508. When the sliding plate 3003 moves, the sleeve plate 3002 is driven to move synchronously through the linkage. At the same time, the stroke limit block 3012 moves with the sleeve plate 3002. When the stroke limit block 3012 moves to the end of the stroke, the stroke limit block 3012 is limited by the stroke limit groove 3011, so that the sleeve plate 3002 stops moving and the linkage loses its coordination.

[0132] When the sleeve plate 3002 and the travel limit block 3012 stop moving, the sliding plate 3003 continues to move to drive the driven gear 3001 to rotate by driving the rack plate 30. When the driven gear 3001 rotates, the transmission column 3007 is driven to rotate through the No. 3 bevel gear set 3009, and then the transmission rod 506 is driven to rotate through the No. 2 bevel gear set 3008. The rotation of the transmission rod 506 corresponds to the work of the lifting assembly.

[0133] When the sliding plate 3003 moves, it can drive the sleeve plate 3002 to retract and release the support through the connecting parts, and at the same time, the sliding plate 3003 can continue to move after the sleeve plate 3002 is retracted, and the subsequent continued movement can drive the work of the lifting component.

[0134] When the electric push rod 508 is working, its movable rod pushes the sliding plate 3003 to move, which pushes the sleeve plate 3002 to move and at the same time makes the associated parts fit together again.

[0135] It should be noted that the third bevel gear set 3009 includes two bevel gears that mesh with each other, one of which is coaxially fixed with the transmission column 3007, and the other is coaxially fixed with the driven gear 3001. The second bevel gear set 3008 also includes two bevel gears that mesh with each other, and the two bevel gears are coaxially fixed with the transmission column 3007 and the transmission rod 506 respectively.

[0136] The connecting parts include multiple movable holes 3005 equidistantly opened on the sliding plate 3003, and a top smooth shaft 3004 is slidably installed in the multiple movable holes 3005. A spring 3006 is fixed to the end of the top smooth shaft 3004, and the other end of the spring 3006 is fixed to the bottom of the movable hole 3005.

[0137] The inner wall of the sleeve plate 3002 is provided with a plurality of arc grooves 3013 equidistantly spaced to cooperate with the top smooth shaft 3004 .

[0138] In an embodiment of the present invention, in the initial state, the top smooth shaft 3004 is located in the arc groove 3013. When the sliding plate 3003 moves, the top smooth shaft 3004 and the arc groove 3013 cooperate to drive the sleeve plate 3002 to follow the movement. When the sleeve plate 3002 moves, it drives the travel limit block 3012 to move. When the travel limit block 3012 moves to the end of the travel of the travel limit groove 3011, the travel limit block 3012 is limited, so that when the sliding plate 3003 continues to move, the top smooth shaft 3004 and the arc groove 3013 cooperate to compress the spring 3006, so that the top smooth shaft 3004 shrinks into the movable hole 3005, and then the sliding plate 3003 continues to move. The movement at this time does not drive the sleeve plate 3002 to move.

[0139] When the sliding plate 3003 returns, the top smooth shaft 3004 will overlap with the arc groove 3013 again, thereby releasing the elastic potential energy of the spring 3006 when it is compressed, so that the top smooth shaft 3004 will be in the arc groove 3013 again, so that when the sliding plate 3003 retracts next time, the top smooth shaft 3004 and the arc groove 3013 can be retracted to drive the sleeve plate 3002 to follow the movement again.

[0140] The function of this embodiment is that after the sleeve plate 3002 is retracted, the sliding plate 3003 can move, thereby driving the lifting component to work.

[0141] It should be noted that this embodiment is an optimization and improvement of the above embodiment, and the sleeve plate 3002 in this embodiment is used to equivalently replace the middle baffle 5 in the above embodiment.

[0142] When the present invention is in use (working), with the assistance of the pushing assembly, the shell plate 4 is added into the first storage box 2 and the second storage box 201 and stacked in sequence.

[0143] Through the cooperation of the translation mechanism and the delivery assembly, the shell panels 4 stored in the No. 1 storage box 2 and the No. 2 storage box 201 are delivered to the designated positions in sequence, so that the delivered shell panels 4 are spliced ​​and fixed in position.

[0144] Then, the four shell plates 4 are welded and fixed together by welding the assembly.

[0145] Finally, the frame formed by welding the four shell plates 4 is pushed out by the lifting assembly, and finally, the frame is taken out by the gripping device.

[0146] Automatic welding can be achieved by repeating the above description.
