Description

Technical Field

[0001] This application relates to the fields of machining and automatic welding equipment, and in particular to a fully automatic welding device and welding method for CDU replenishment tanks. Background Technology

[0002] In existing technologies, the welding of square replenishment water tanks typically employs an automatic welding torch in conjunction with a universal positioning fixture. The operator first places the tank plate to be welded into the stationary positioning fixture, clamps it securely, starts the welding equipment, and then manually releases the clamp and flips the tank before proceeding to the next weld. This method results in low overall welding efficiency and difficulty in guaranteeing weld quality. Solving these technical problems is a matter that those skilled in the art need to consider. Summary of the Invention

[0003] To address the aforementioned technical problems, this application provides a fully automatic welding device and welding method for CDU replenishment tanks.

[0004] This application provides a fully automatic welding device for CDU replenishment tanks, used for welding plates to obtain cuboid-shaped replenishment tanks, including a clamping assembly and a welding assembly. The clamping assembly includes a rotatably configured clamping member for clamping and fixing the end of the unfinished replenishment tank, causing the tank to rotate about a straight line parallel to a first direction, exposing the welded surface of the unfinished tank upwards along a second direction perpendicular to the first direction. The welding assembly includes a three-axis drive component and a welding component, driven by the three-axis drive component. The welding component moves relative to the welding surface along the first direction, the second direction, and a third direction perpendicular to both directions, and is suspended above the welding surface along the second direction. The welding component is configured to output heat and complete the welding of the replenishment tank.

[0005] Understandably, the fully automatic welding device for CDU replenishment tanks provided in this application embodiment, by clamping the end of the replenishment tank with a clamping component and driving it to rotate around a straight line parallel to the first direction, enables the two sides of the replenishment tank containing the strip weld in the first direction to face upwards in the second direction in sequence, thereby allowing the welds on different sides to be exposed sequentially at the welding station. In conjunction with the three-axis drive component in the welding assembly, the welding assembly is moved in three-dimensional space and suspended above the welding surface, allowing the welding assembly to automatically track and cover the strip weld extending along the first direction. This structural design, through the coordination of the clamping component's rotation and the three-axis movement of the welding assembly, replaces the traditional manual method of loosening the clamps, moving and flipping the replenishment tank, and then re-clamping it, reducing auxiliary time during the welding process. Simultaneously, it provides more accurate alignment, which is beneficial for improving the welding efficiency of the replenishment tank and the consistency of the weld formation.

[0006] In one embodiment, the clamping component is further configured to be driven to rotate in a third direction to cause the unfinished replenishment tank to rotate in a third direction, so that at least one end face of the unfinished replenishment tank is exposed upward in a second direction.

[0007] Understandably, by utilizing the structural feature of the clamping component being driven to rotate around a third direction, the CDU fully automatic welding device for replenishing water tanks can change the posture of the replenishing water tank in space, adjusting the end face that was originally perpendicular to the horizontal plane to a state exposed along the second direction, which is beneficial for achieving continuous welding of multi-angle welds on the replenishing water tank.

[0008] In one embodiment, the fully automatic welding device for CDU replenishment tanks further includes a steering assembly, which is spaced apart from the clamping component along a first direction. The steering assembly is configured to be driven to rotate around a straight line parallel to a second direction, and is used to carry and drive the replenishment tank to rotate, so that the end face of the replenishment tank that is not welded due to being clamped by the clamping component is exposed.

[0009] Understandably, because the clamping component needs to hold one end of the replenishing fluid tank during operation, the clamped area of ​​the replenishing fluid tank and the nearby weld seam become a blind spot that cannot be welded. The steering assembly, spaced apart from the clamping component along the first direction, can support the replenishing fluid tank. Utilizing its own property of rotating in a straight line parallel to the second direction, the steering assembly can turn the replenishing fluid tank horizontally, thereby exposing the area previously held by the clamping component. The coordinated design of the clamping and steering assemblies enables automatic reversal of the workpiece, facilitating complete welding of the replenishing fluid tank from all directions.

[0010] In one embodiment, the steering assembly includes a support frame and a plurality of abutments. The support frame has a receiving groove for accommodating a replenishment tank, and the plurality of abutments are built into the receiving groove and connected to the support frame for fixing the replenishment tank.

[0011] Understandably, the receiving groove on the support frame provides a clear placement space for the replenishing water tank, serving as an initial positioning limit. Multiple abutment members built into the receiving groove connect to the support frame, directly contacting and securing the replenishing water tank. During the rotation of the replenishing water tank by the steering assembly, the abutment members provide the necessary clamping force to prevent relative displacement or swaying of the replenishing water tank under centrifugal force, thus ensuring the stability of the rotation reversal process and the accuracy of subsequent welding positions.

[0012] In one embodiment, the steering assembly is further configured to be driven to move along a first direction. The steering assembly also includes a plurality of rollers, which are built into a receiving groove and are lower than a plurality of abutment members along a second direction. The plurality of rollers are located on the same horizontal plane and are equally spaced. The axial directions of the plurality of rollers are parallel to each other and rotatably connected to the support frame. The steering assembly is also configured to be driven to move along a second direction to drive the plurality of rollers to roll and connect with the bottom wall of replenishment tanks of different sizes.

[0013] Understandably, the steering assembly is driven to move along the first direction, adjusting its position according to the length specifications of the replenishing fluid tank to accommodate the load-bearing requirements of replenishing fluid tanks of different sizes. Multiple rollers contact the bottom wall of the replenishing fluid tank, and the low-friction characteristics of the rollers themselves assist the movement of the replenishing fluid tank, reducing scratches on the surface of the replenishing fluid tank. The steering assembly is constructed to move along both the first and second directions, adapting to replenishing fluid tanks of different sizes, improving the applicability and efficiency of the CDU fully automatic replenishing fluid tank welding device, and balancing the flexibility of replenishing fluid tank movement with the stability during welding.

[0014] In one embodiment, the steering assembly further includes a scraper and a collector. The scraper is slidably connected to the support frame along a second direction and is used to scrape off welding slag from the weld seam of the replenishing water tank after welding. The collector is spaced below the scraper along the second direction and is used to collect welding slag that falls from the replenishing water tank.

[0015] Understandably, the scraper component slides along the second direction to the support frame. The scraper component moves in close contact with the weld surface, mechanically scraping away weld slag or spatter generated during welding, replacing manual cleaning. The collector located below the scraper component along the second direction collects and gathers fallen waste, preventing weld slag from scattering onto the steering assembly and damaging it, or causing environmental pollution. The scraper component and collector work together to improve the post-weld processing efficiency of the fully automated welding device for the CDU replenishment tank.

[0016] In one embodiment, the clamping component includes a rotating base and a chuck. The rotating base is rotatably connected to the chuck and is used to drive the chuck to rotate around a third direction. The chuck is configured to rotate on a straight line parallel to the first direction as an axis. The chuck is used to clamp and fix the end of the unfinished replenishment tank.

[0017] Understandably, the chuck is used to clamp and drive the replenishing water tank to rotate around the first direction. The rotating base is used to drive the chuck and the replenishing water tank clamped by the chuck to rotate around the third direction, so as to meet the welding requirements of the annular weld on the end face of the replenishing water tank.

[0018] In one embodiment, the fully automatic welding device for CDU replenishment tanks further includes a support member and a clamping fixture. The support member has a first clamping station along the second direction, and the clamping fixture is connected above the support member along the second direction. The clamping fixture has a second clamping station along the second direction. The first clamping station and the second clamping station cooperate to expose the welded surface of the unfinished replenishment tank facing upward along the second direction.

[0019] Understandably, the support component and the clamping fixture are respectively equipped with a first clamping station and a second clamping station, forming a fit along the second direction. These stations distributed along the second direction provide auxiliary support when welding the circumferential weld on the end face of the replenishing water tank. The fit between the first and second clamping stations securely restricts the degree of freedom of the replenishing water tank, preventing warping due to thermal deformation during welding and thus ensuring a higher welding success rate.

[0020] In one embodiment, the fully automatic welding device for CDU replenishment tanks further includes a sensor assembly and a control unit. The sensor assembly includes a position sensor and a distance sensor. The position sensor is connected to the welding component to sense the position of the weld, and the distance sensor is connected to the steering assembly to sense the distance to the replenishment tank. The position sensor and the distance sensor are respectively communicatively connected to the control unit.

[0021] Understandably, the position sensor, connected to the welding components, can feed back the actual position information of the weld to the control unit in real time, allowing the control unit to correct the welding path based on deviations. The distance sensor monitors the relative distance between the replenishment tank and the steering assembly, providing data support for the movement and docking of the steering assembly and preventing collisions. By coordinating the electrical connections and signal processing of all components, the control unit achieves closed-loop control of the welding process, reducing reliance on human experience and improving the automation level of the equipment.

[0022] This application embodiment also provides a fully automatic welding method for CDU replenishment water tanks, including the following steps: Step S1: The clamping component clamps the unfinished replenishment water tank, exposing one welding surface of the unfinished replenishment water tank upward along a second direction. A three-axis drive component drives a welding component to suspend above the corresponding welding surface, and the welding component welds a weld seam extending along a first direction on the welding surface of the replenishment water tank. Step S2: The clamping component rotates the unfinished replenishment water tank 180 degrees around a straight line parallel to the first direction, exposing the other welding surface of the unfinished replenishment water tank upward along the second direction. The three-axis drive component drives a welding component to suspend above the corresponding welding surface, and the welding component welds another weld seam extending along the first direction on the welding surface of the replenishment water tank. Step S3: The clamping component rotates the replenishing water tank 90 degrees around a straight line parallel to the third direction, exposing the end face of the replenishing water tank facing upwards along the second direction. The three-axis drive component drives the welding component to suspend above the corresponding welding surface. The welding component moves to weld the weld seam of the replenishing water tank connected around the second direction. Step S4: The clamping component clamps the replenishing water tank and rotates it 90 degrees around a straight line parallel to the third direction to the position in Step S1. The clamping component releases the replenishing water tank, and the steering component clamps the replenishing water tank and rotates it around a straight line parallel to the second direction. Step S5: The clamping component clamps the replenishing water tank and rotates it 90 degrees around a straight line parallel to the third direction. The welding component welds the weld seam of the replenishing water tank connected around the second direction.

[0023] Understandably, the fully automated welding method for CDU replenishment tanks utilizes the rotation function of the clamping components in steps S1 and S2 to complete the welding of long welds extending along the first direction on both sides of the replenishment tank; in step S3, the flipping function of the clamping components adjusts the end face weld of one end of the replenishment tank to a weldable position and completes the welding; in step S4, the introduction of the steering component clamps and rotates the replenishment tank, achieving automatic turning of the replenishment tank and solving the problem of the other end being unable to be welded due to clamping the replenishment tank on one side; finally, in step S5, the flipping function is used again to complete the welding of the remaining end face. This forms a complete fully automated welding process, reducing intermediate stops and manual intervention, and improving the overall production efficiency of CDU replenishment tanks.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 This application will be described in further detail below.

[0031] Example 1: In one embodiment, a fully automatic welding device for CDU replenishment tanks is used to weld plates to obtain a cuboid-shaped replenishment tank 1. The device includes a clamping assembly 2 and a welding assembly 3. The clamping assembly 2 includes a rotatably configured clamping member 21, which clamps and fixes the unfinished end of the replenishment tank 1, causing the tank to rotate about a straight line parallel to the first direction X, so that the welding surface of the unfinished replenishment tank 1 is exposed upwards along the second direction Z, which is perpendicular to the first direction X. The welding assembly 3 includes a three-axis drive member 31 and a welding member 32. The welding member 32 is drivenly connected to the three-axis drive member 31, and is used to move the welding member 32 relative to the welding surface along the first direction X, the second direction Z, and a third direction Y perpendicular to both directions X and Z. The welding member 32 is suspended above the welding surface along the second direction Z. The welding member 32 is configured to output heat and complete the welding of the replenishment tank 1.

[0032] In this embodiment, reference Figure 1 , Figure 2 and Figure 3A three-axis drive component 31 is spaced apart from the clamping component 21. The three-axis drive component 31 is connected to the welding component 32 and is used to drive the welding component 32 to move along the first direction X, the second direction Z, and the third direction Y. The three-axis drive component 31 can also drive the welding component 32 to rotate around the third direction Y. The three-axis drive component 31 can be a multi-axis drive structure that integrates at least drive components for the first direction X, the second direction Z, and the third direction Y. The linear drive method in each direction includes, but is not limited to, known and feasible structures such as linear motors and motor lead screws. The welding component 32 can be a welding torch capable of performing argon arc welding. The clamping component 21 is spaced apart and positioned below the welding component 32 along the second direction Z.

[0033] The fully automatic welding device for CDU replenishing water tanks provided in this application embodiment uses a clamping component 21 to clamp the end of the replenishing water tank 1 and drive it to rotate around a straight line parallel to the first direction X. This allows the two sides of the replenishing water tank 1 containing the strip weld located in the first direction X to face upwards sequentially along the second direction Z, thus exposing the welds on different sides to the welding station in sequence. In conjunction with the three-axis drive component 31 in the welding assembly 3, the welding component 32 is moved in three-dimensional space and suspended above the welding surface, enabling the welding component 32 to automatically track and cover the strip weld extending along the first direction X. This structural design, through the coordination of the rotation of the clamping component 21 and the three-axis movement of the welding component 32, replaces the traditional manual method of loosening the clamps, moving and flipping the replenishing water tank 1, and then re-clamping it. This reduces auxiliary time during the welding process and helps improve the welding efficiency of the replenishing water tank 1 and the consistency of the weld formation.

[0034] The clamping assembly 2 is mounted on the support member 5 of the device. The clamping component 21 mainly consists of a rotating base 211 and a chuck 212. The chuck 212 includes an openable and closable jaw structure 2121. The chuck 212 is disc-shaped, and the jaw structure 2121 is L-shaped. The jaw structure 2121 is slidably connected to the side wall of the chuck away from the rotating base 211. The jaw structure 2121 is used to securely clamp the end connection port or the edge of the replenishment tank 1.

[0035] The rotating base 211 serves as the support carrier for the chuck 212. The rotating base 211 has an accommodating space, and part of the chuck 212 is built into the accommodating space and rotates to be connected to the rotating base 211. The chuck 212 can rotate 360 ​​degrees around the first direction X.

[0036] The three-axis drive component 31 adopts a cantilever structure, including linear guides set along the first direction X and the second direction Z, and a telescopic connecting rod set along the third direction Y. Through the combination of motion in the three directions, the three-axis drive component 31 constructs a three-dimensional coordinate system covering the welding area of ​​the replenishing water tank 1, which can drive the welding component 32 to move precisely to any coordinate point within the welding area, and keep the welding component 32 suspended directly above the surface to be welded along the second direction Z, so as to weld welds located at different positions in the replenishing water tank 1.

[0037] The welding component 32 can be equipped with an automatic argon arc welding torch. The welding component 32 has a columnar design, and the welding interface of the welding component 32 is set downward along the second direction Z. The optimal angle of the heat source output is used to melt the welding material and improve the welding quality. The execution end of the three-axis drive component 31 is connected to the middle position of the welding component 32 along the second direction Z to increase the stability with the welding component 32.

[0038] In one embodiment, the fully automatic welding device for CDU replenishment tanks further includes a support member 5 and a clamping fixture 6. The support member 5 has a first clamping station 51 along the second direction Z. The clamping fixture 6 is connected above the support member 5 along the second direction Z. The clamping fixture 6 has a second clamping station 61 along the second direction Z. The first clamping station 51 and the second clamping station 61 cooperate to expose the welding surface of the unfinished replenishment tank 1 facing upward along the second direction Z.

[0039] In this embodiment, refer to Figure 1 and Figure 3 The support member 5 can be a cuboid machine tool. The clamping component 21 is movably connected to the support member 5 above along the second direction Z. The three-axis drive component 31 is connected to the side wall of the support member 5. The clamping fixture 6 is cuboid in shape and is placed above the support member 5 along the second direction Z. The support member 5 and the clamping fixture 6 are respectively provided with a first clamping station 51 and a second clamping station 61, forming a fit along the second direction Z. This arrangement of stations along the second direction Z provides auxiliary support when welding the circumferential weld on the end face of the replenishing water tank 1. The fit between the first clamping station 51 and the second clamping station 61 stably restricts the degree of freedom of the replenishing water tank 1, preventing warping due to thermal deformation during welding and thus ensuring a high welding success rate.

[0040] The implementation principle of this application embodiment is as follows: The clamping component 21 clamps the replenishing water tank 1 to be welded and rotates it around a straight line parallel to the first direction X. The welding component 32 welds two strip-shaped welds along the length direction of the replenishing water tank 1. Subsequently, the clamping component 21 releases the replenishing water tank 1, and the tank body of the replenishing water tank 1 after the strip-shaped welds are welded is manually flipped so that its length direction is parallel to the second direction Z. The replenishing water tank 1 is then placed between the first clamping station 51 and the second clamping station 61, and the welding component 32 performs spot welding on a ring of welds at the end of the replenishing water tank 1. Afterward, the tank body of the replenishing water tank 1 is manually flipped 180 degrees so that the other end face of the replenishing water tank 1 is exposed upward along the second direction Z, and the replenishing water tank 1 is partially placed between the first clamping station 51 and the second clamping station 61. The welding component 32 performs spot welding on a ring of welds at the end of the replenishing water tank 1.

[0041] Example 2: Based on the structure disclosed in Example 1, Example 2 further includes the following structural improvements: In one embodiment, the clamping member 21 is also configured to be driven to rotate around a third direction Y, for driving the unfinished replenishment tank 1 to rotate around a third direction Y, so that at least one end face of the unfinished replenishment tank 1 is exposed upward along the second direction Z.

[0042] In this embodiment, refer to Figure 1 and Figure 3 The clamping component 21 can rotate around a straight line parallel to the first direction X, and can also be driven to flip around a third direction Y. Through the structural feature of the clamping component 21 being driven to flip around a third direction Y, the CDU replenishment water tank fully automatic welding device can change the posture of the replenishment water tank 1 in space, adjusting the end face that was originally perpendicular to the horizontal plane to a state exposed along the second direction Z, which is beneficial to realize the continuous welding of multi-angle welds of the replenishment water tank 1.

[0043] The implementation principle of this application embodiment is as follows: The clamping component 21 holds the replenishing water tank 1 to be welded and rotates it around a straight line parallel to the first direction X. The welding component 32 welds two strip-shaped welds along the length of the replenishing water tank 1. Then, the clamping component 21 drives the replenishing water tank 1 to rotate 90 degrees around a straight line parallel to the third direction Y, so that one end face of the replenishing water tank 1 is exposed upward along the second direction Z. The welding component 32 performs spot welding on a ring of welds at the end of the replenishing water tank 1. After that, the clamping component 21 drives the replenishing water tank 1 to rotate 90 degrees in the opposite direction around a straight line parallel to the third direction Y, so that the replenishing water tank is in the posture before rotation. Subsequently, the clamping component 21 releases the replenishing water tank 1, and the replenishing water tank 1 is manually rotated 180 degrees around a straight line parallel to the second direction Z. The clamping component 21 clamps the welded end of the replenishing water tank 1, and the clamping component 21 drives the replenishing water tank 1 to rotate 90 degrees around a straight line parallel to the third direction Y, so that the other end face of the replenishing water tank 1 is exposed upward along the second direction Z. The welding component 32 performs spot welding on a ring of weld seams at the end of the replenishing water tank 1.

[0044] Example 3: Based on the structure disclosed in Example 2, Example 3 further includes the following structural improvements: In one embodiment, reference is made to Figure 1 and Figure 3 The clamping component 21 includes a rotating base 211 and a chuck 212. The rotating base 211 is rotatably connected to the chuck 212 and is used to drive the chuck 212 to rotate around a third direction Y. The chuck 212 is configured to rotate on a straight line parallel to the first direction X. The chuck 212 is used to clamp and fix the end of the unfinished replenishment water tank 1.

[0045] In this embodiment, both the rotating base 211 and the chuck 212 can be made of sturdy metal. The rotating base 211 is rotatably connected to the chuck 212. The chuck 212 is disc-shaped, and multiple adjustable jaw structures 2121 are distributed on its circumference. The jaw structures 2121 can be driven to open and close, thereby clamping and fixing the end of the replenishment tank 1. The chuck 212 can rotate about a straight line parallel to the first direction X.

[0046] The clamping component 21 is refined into a combination of a rotating base 211 and a chuck 212, achieving decoupling of the motion dimension. The chuck 212 is used to clamp and drive the replenishing water tank 1 to rotate around the first direction X. The rotating base 211 is used to drive the chuck 212 and the replenishing water tank 1 clamped by the chuck 212 to rotate around the third direction Y, meeting the welding requirements of the annular weld on the end face of the replenishing water tank 1. The split structure of the clamping component 21 clarifies the force and motion functions of each component, which helps to simplify the control logic and improve the rigidity and stability of the mechanical structure when subjected to cantilever loads.

[0047] In one embodiment, the fully automatic welding device for CDU replenishment tanks further includes a steering component 4, which is spaced apart from the clamping component 21 along the first direction X. The steering component 4 is configured to be driven to rotate around a straight line parallel to the second direction Z, and is used to carry and drive the replenishment tank 1 to rotate, so that the end face of the replenishment tank 1 that is not welded due to being clamped by the clamping component 21 is exposed.

[0048] In this embodiment, refer to Figure 1 , Figure 3 and Figure 4 The steering assembly 4 is a rectangular plate and is connected to the three-axis drive component 31. Because the clamping component 21 needs to clamp one end of the replenishing water tank 1 during operation, the clamped area of ​​the replenishing water tank 1 and the nearby weld seam become a blind spot that cannot be welded. The steering assembly 4, by being spaced apart from the clamping component 21 along the first direction X, can support the replenishing water tank 1. Utilizing its own characteristic of rotating around a straight line parallel to the second direction Z, the steering assembly 4 can drive the replenishing water tank 1 to turn horizontally, thereby exposing the area originally clamped by the clamping component 21. The design of the clamping assembly 2 and the steering assembly 4 together realizes automatic reversal of the workpiece, which helps to achieve complete welding of the replenishing water tank 1 from all directions.

[0049] In one embodiment, the fully automatic welding device for CDU replenishment tanks further includes a sensor assembly 7 and a control unit 8. The sensor assembly 7 includes a position sensor 71 and a distance sensor 72. The position sensor 71 is connected to the welding component 32 to sense the position of the weld seam, and the distance sensor 72 is connected to the steering assembly 4 to sense the distance of the replenishment tank 1. The position sensor 71 and the distance sensor 72 are respectively communicatively connected to the control unit 8.

[0050] In this embodiment, refer to Figure 1 , Figure 2 and Figure 3 Both position sensor 71 and distance sensor 72 can be photoelectric sensors. Position sensor 71 is connected to the position corresponding to the welding component 32 of the three-axis drive component 31, and distance sensor 72 is connected above the steering assembly 4 along the second direction Z. The control unit 8 is located at the position of the steering assembly 4 away from the three-axis drive component 31 along the third direction Y. Position sensor 71, connected to welding component 32, can feed back the actual position information of the weld to control unit 8 in real time, allowing control unit 8 to correct the welding path according to the deviation. Distance sensor 72 monitors the relative distance between the replenishment water tank 1 and steering assembly 4, providing data support for the movement and docking of steering assembly 4 and preventing collisions. Control unit 8, by coordinating the electrical connections and signal processing of various components, realizes closed-loop control of the welding process, reduces reliance on human experience, and improves the automation level of the equipment.

[0051] In one embodiment, the steering assembly 4 includes a support frame 41 and a plurality of abutment members 42. The support frame 41 has a receiving groove 411 for accommodating the replenishing water tank 1. The plurality of abutment members 42 are built into the receiving groove 411 and connected to the support frame 41 for fixing the replenishing water tank 1.

[0052] In this embodiment, refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The support frame 41 includes a rotating part 413 and two supporting parts 412. The rotating part 413 is arranged along a first direction X, and the supporting parts 412 are arranged along a second direction Z. The two supporting parts 412 are spaced apart along a third direction Y and connected to the rotating part 413. The abutting member 42 includes a connecting part 422 and an abutting part 421 that is rollably connected to the connecting part 422. The end of the connecting part 422 away from the abutting part 421 is elastically connected to the support member 5. Some abutting members 42 are elastically connected to one supporting part 412, and some abutting members 42 are arranged at equal intervals along the first direction X; the remaining abutting members 42 are elastically connected to another supporting part 412, and the remaining abutting members 42 are arranged at equal intervals along the first direction X. The abutting members 42 cooperate with the supporting parts 412 to snap onto replenishment water tanks 1 of different sizes.

[0053] The receiving groove 411 on the support frame 41 provides a clear placement space for the replenishing water tank 1, serving as a preliminary positioning element. Multiple abutment members 42, built into the receiving groove 411, are connected to the support frame 41, directly contacting and securing the replenishing water tank 1. During the rotation of the replenishing water tank 1 by the steering assembly 4, the abutment members 42 provide the necessary clamping force to prevent relative displacement or swaying of the replenishing water tank 1 under centrifugal force, thus ensuring the stability of the rotation reversal process and the accuracy of subsequent welding positions.

[0054] In one embodiment, the steering assembly 4 is further configured to be driven to move along a first direction X. The steering assembly 4 also includes a plurality of rollers 43, which are built into a receiving groove 411 and are lower than a plurality of abutment members 42 along a second direction Z. The plurality of rollers 43 are located on the same horizontal plane and are equally spaced. The axial directions of the plurality of rollers 43 are parallel to each other and are rotatably connected to the support frame 41. The steering assembly 4 is also configured to be driven to move along a second direction Z to drive the plurality of rollers 43 to roll and connect with the bottom wall of the replenishment water tank 1 of different sizes.

[0055] In this embodiment, refer to Figure 3 and Figure 4Multiple rollers 43 are built into the receiving groove 411 and rotatably connected to the bogie. The steering assembly 4 is driven to move along the first direction X, and its position can be adjusted according to the length specification of the replenishing water tank 1 to adapt to the load-bearing requirements of replenishing water tanks 1 of different sizes. The multiple rollers 43 contact the bottom wall of the replenishing water tank 1, and the rollers 43 assist the movement of the replenishing water tank 1 through their own low-friction rolling characteristics, reducing scratches on the surface of the replenishing water tank 1. The steering assembly 4 is constructed to move along the first direction X and the second direction Z to adapt to replenishing water tanks 1 of different sizes, improving the applicability and efficiency of the CDU replenishing water tank fully automatic welding device, and taking into account both the flexibility of the replenishing water tank 1 movement and the stability during welding.

[0056] In one embodiment, the steering assembly 4 further includes a scraper 44 and a collector 45. The scraper 44 is slidably connected to the support frame 41 along the second direction Z. The scraper 44 is used to scrape off the welding slag on the weld of the replenishing water tank 1 after welding. The collector 45 is spaced below the scraper 44 along the second direction Z. The collector 45 is used to collect the welding slag that falls from the replenishing water tank 1.

[0057] In this embodiment, refer to Figure 1 and Figure 4 The steering assembly 4 also includes two scraping elements 44, which are built into the receiving groove 411 and fixedly connected to the support frame 41. The axial direction of the scraping elements 44 is parallel to the axial direction of the roller. The scraping elements 44 are slidably connected to the support frame 41 along the second direction Z. The scraping elements 44 can move in close contact with the weld surface and remove welding slag or spatter generated during the welding process by mechanical scraping, replacing the manual cleaning process. The collecting element 45 located below the scraping elements 44 along the second direction Z is used to receive and collect the fallen waste, preventing welding slag from scattering on the steering assembly 4 and damaging the steering assembly 4 or causing environmental pollution. The scraping elements 44 and the collecting element 45 work together to improve the post-weld processing efficiency of the CDU replenishment water tank fully automatic welding device and help maintain a clean processing environment.

[0058] The implementation principle of this application embodiment is as follows: The clamping component 21 clamps the replenishing water tank 1 to be welded and rotates it around a straight line parallel to the first direction X. The welding component 32 welds two strip-shaped welds along the length of the replenishing water tank 1. Subsequently, the clamping component 21 drives the replenishing water tank 1 to rotate 90 degrees around a straight line parallel to the third direction Y, so that one end face of the replenishing water tank 1 is exposed upward along the second direction Z. The welding component 32 performs spot welding on a ring of welds at the end of the replenishing water tank 1. Then, the clamping component 21 drives the replenishing water tank 1 to rotate 90 degrees in the opposite direction around a straight line parallel to the third direction Y, so that the replenishing water tank is in the posture before rotation. Subsequently, the clamping component 21 releases the replenishing water tank 1, and the steering component 4 clamps the replenishing water tank 1 and rotates it 180 degrees around a straight line parallel to the second direction Z, exchanging the positions of the two ends of the replenishing water tank 1 along the first direction X. The clamping component 21 clamps the welded end of the replenishing water tank 1. The clamping component 21 drives the replenishing water tank 1 to rotate 90 degrees around a straight line parallel to the third direction Y, so that the other end face of the replenishing water tank 1 is exposed upward along the second direction Z. The welding component 32 performs spot welding on a ring of weld seams at the end of the replenishing water tank 1.

[0059] Example 4: This application also provides a fully automated welding method for CDU replenishment tanks, including the following steps: Step S1: Clamping component 21 clamps the unfinished replenishing water tank 1, exposing one welding surface of the unfinished replenishing water tank 1 upward along the second direction Z. Three-axis drive component 31 drives welding component 32 to be suspended above the corresponding welding surface. Welding component 32 welds a weld seam extending along the first direction X on the welding surface of replenishing water tank 1.

[0060] Step S2: The clamping component 21 clamps the unfinished replenishing water tank 1 and rotates it 180 degrees around a straight line parallel to the first direction X, so that the other welding surface of the unfinished replenishing water tank 1 is exposed upward along the second direction Z. The three-axis drive component 31 drives the welding component 32 to be suspended above the corresponding welding surface. The welding component 32 welds another weld seam extending along the first direction X on the welding surface of the replenishing water tank 1.

[0061] Step S3: The clamping component 21 drives the replenishing water tank 1 to rotate 90 degrees around a straight line parallel to the third direction Y, so that the end face of the replenishing water tank 1 is exposed upward along the second direction Z. The three-axis drive component 31 drives the welding component 32 to be suspended above the corresponding welding surface. The welding component 32 moves to weld the weld seam of the replenishing water tank 1 connected around the second direction Z.

[0062] Step S4: The clamping component 21 clamps the replenishing water tank 1 and rotates it 90 degrees around the axis of the straight line parallel to the third direction Y to the position in step S1. The clamping component 21 releases the replenishing water tank 1, and the steering component 4 clamps the replenishing water tank 1 and rotates it 180 degrees around the axis of the straight line parallel to the second direction Z.

[0063] Step S5: Clamping component 21 clamps the replenishing water tank 1 and rotates it 90 degrees around the straight line parallel to the third direction Y. Welding component 32 welds the weld seam of the replenishing water tank 1 around the second direction Z. In this embodiment, the fully automated welding method for the CDU replenishment tank utilizes the rotation function of the clamping component 21 in steps S1 and S2 to weld two strip-shaped welds along the length of the replenishment tank 1. In step S3, the flipping function of the clamping component 21 is used to adjust the end face weld of one end of the replenishment tank 1 to a weldable position and complete the welding. In step S4, the steering component 4 is introduced to clamp and rotate the replenishment tank 1, achieving automatic turning of the replenishment tank 1 and solving the problem of the other end of the replenishment tank 1 being unweldable when the clamping component 21 clamps the replenishment tank 1 on only one side. Finally, in step S5, the flipping function of the clamping component 21 is used again to complete the welding of the other end face of the replenishment tank 1. Through a complete fully automated welding process, interruptions and manual intervention in intermediate steps are reduced, thereby improving the overall welding efficiency of the replenishment tank 1.

[0064] The implementation principle of this application embodiment is as follows: The fully automatic welding method for CDU replenishment tanks uses the clamping component 21 to drive the replenishment tank 1 to rotate and flip, while the three-axis drive component 31 drives the welding component 32, thus achieving orderly welding of each welding surface of the replenishment tank 1. Compared with existing welding methods, this application reduces the time spent manually adjusting the welding angle and position, and improves welding efficiency and welding quality.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
