[0001] This application relates to the field of welding technology for intersecting pipes, and in particular to a welding apparatus. Background Technology

[0002] Intersecting pipes, as key components of flow battery energy modules, have received widespread attention and research in recent years. Intersecting pipes generally consist of a main pipe and branch pipes, with the branch pipes needing to be welded to specific locations on the main pipe according to strict dimensional requirements.

[0003] In related technologies, branch pipes are typically welded to main pipes manually, and the welding effect is inspected visually.

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] Considering that existing intersecting pipelines are generally welded to the main pipeline by manual welding, and the welding effect is inspected visually, the assembly of intersecting pipelines welded by this manual welding method often fails due to dimensional inaccuracies, requiring frequent rework and remanufacturing, which is time-consuming and labor-intensive. This application provides a welding device 1, which can improve welding accuracy, thereby avoiding assembly failures caused by dimensional inaccuracies, effectively reducing the working time and intensity of workers, and facilitating its application and promotion.

[0036] For details, please refer to Figure 1 One embodiment of this application provides a welding apparatus 1, which may include a base 100, a track 200, a heat fusion mechanism 300, a first limiting component 400, and a second limiting component 500. The track 200 is disposed on the base 100. The heat fusion mechanism 300 is disposed on the track 200 and is movable along the track 200. The heat fusion mechanism 300 is used for welding the main pipe 10 (see...) Figure 4 Heating is performed. The first limiting assembly 400 includes at least two first limiting members 410, which are spaced apart along a direction parallel to the track 200. Each first limiting member 410 is used to limit the hot-melt mechanism 300 at each hot-melt position on the track 200. The second limiting assembly 500 is used to limit the main pipe 10 so that the main pipe 10 is arranged parallel to the track 200, and so that each weld point of the main pipe 10 corresponds to each hot-melt position in a preset relative position.

[0037] It should be noted that each of the aforementioned welding points and each hot melt position are set in a one-to-one correspondence with a preset relative position. This can be because the number of welding points on the main pipe 10 that need to be welded is equal to the number of the first limiting members 410. Then, when the hot melt mechanism 300 is limited to each first limiting member 410, there is a corresponding welding point that corresponds to it in a preset relative position. This welding point serves as the welding point of the hot melt mechanism 300 at that hot melt position.

[0038] The aforementioned welding device 1, through the setting of the first limiting component 400 and the second limiting component 500, enables the hot melt mechanism 300 to run precisely on the track 200 to each hot melt position, and enables each welding point on the main pipe 10 to correspond one-to-one with the aforementioned hot melt position in a preset relative position. This improves the accuracy of the hot melt mechanism 300 at each welding point, reduces the welding size deviation of the branch pipe 20 on the main pipe 10, improves the welding effect, and consequently reduces the problem of assembly failure due to non-compliance of dimensions when assembling the intersecting pipes after welding.

[0039] Optionally, the weld points on the main pipe 10 may be distributed at equal intervals, but not limited to equal intervals. Optionally, the weld points on the main pipe 10 may be distributed at unequal intervals.

[0040] However, it is worth noting that regardless of how the weld points are distributed, the welding device 1 described above in this application can adjust the distribution position of the first limiting member 410, or adjust the distribution position of the second limiting component, or simultaneously adjust the distribution positions of the first limiting member 410 and the second limiting component, so that when the welding device 1 moves to each hot melt position, it can maintain the aforementioned preset relative position with the corresponding weld point, thereby achieving the accuracy of the hot melt mechanism 300 at the weld point.

[0041] Optionally, the limiting effect of the aforementioned first limiting member 410 on the hot-melt mechanism 300 can be achieved by mutual locking or by the first limiting member locking the hot-melt mechanism 300.

[0042] Optionally, combined Figure 1 As shown, the aforementioned track 200 can be configured as two guide rails, which can improve the operational stability of the hot melt mechanism 300.

[0043] Optionally, combined Figure 3 and Figure 5 As shown, Figure 3 for Figure 2 An enlarged view of the welding device 1 shown at point A. Figure 5 for Figure 4The enlarged view of the welding device 1 shown at point B. The hot melt mechanism 300 may include a mounting base 310, a heating head 320, and a material take-up head 330. The material take-up head 330 is used to fix the branch pipe 20. The hot melt mechanism 300 is used to heat the branch pipe 20 and the main pipe 10. The heating head 320 is mounted on the mounting base 310 and is retractable relative to the mounting base 310 along a first direction X. The material take-up head 330 is mounted on the mounting base 310 and is retractable relative to the mounting base 310 along a second direction Z. The first direction X and the second direction Z intersect. The mounting base 310 is mounted on the track 200.

[0044] Specifically, when the aforementioned hot-melt mechanism 300 is in use, the branch pipe 20 is first fixed by the material taking head 330, then the main pipe 10 is limited on the second limiting component 500, and then the mounting base 310 moves along the track 200 to the first limiting component 410, thus realizing the positioning of the hot-melt mechanism 300.

[0045] Furthermore, the heating head 320 extends from the mounting base 310 along the first direction X to a position between the main pipe 10 and the branch pipe 20, and the heating head can simultaneously contact the weld point of the main pipe 10. The material taking head 330 moves the branch pipe 20 along the second direction Z until the branch pipe 20 contacts the heating head 320. In this way, the heating head 320 can simultaneously heat-melt the weld point of the main pipe 10 and the branch pipe 20. After the main pipe 10 and the branch pipe 20 are heat-melted, the heating head 320 retracts from the mounting base 310 along the first direction X, and the material taking head 330 continues to move the branch pipe 20 along the second direction Z toward the weld point of the main pipe 10 until the branch pipe 20 presses against the weld point, thus realizing the welding of the branch pipe 20 and the main pipe 10.

[0046] Optionally, the heating head 320 may have a first heating surface and a second heating surface, which are arranged on opposite sides of the heating head 320. This allows for simultaneous heating of the weld points of the main pipe 10 and the branch pipe 20, thereby improving the heating effect and facilitating the control of the heating temperature.

[0047] Optionally, please continue reading Figure 3 and Figure 5 The heat-melting mechanism 300 may include a pressing structure 340, which is connected to the material taking head 330. The pressing structure 340 is used to drive the material taking head 330 to move along the second direction Z, so that the branch pipe 20 can be moved toward the heating head 320, so that the heating head 320 heat-melts the branch pipe 20.

[0048] It is worth noting that the setting of the downward pressure structure 340 helps to control the downward pressure, which can improve the consistency of the heat melting effect of the heating head 320 on each branch pipe 20, thereby ensuring the consistency of the welding effect of the intersecting pipe at each welding point.

[0049] Optionally, please continue reading Figure 3 and Figure 5 The hot melt mechanism 300 may include an elastic element 350, which is connected to the feeding head 330. The elastic element 350 is used to elastically deform along the second direction Z under the drive of the feeding head 330. In this way, the feeding head 330 can be automatically elastically pulled back and reset by the elastic element 350, which improves the ease of movement of the branch pipe 20 in the second direction Z.

[0050] For example, after the worker completes the heat fusion of the branch pipe 20 by pressing down the pressing structure 340, he only needs to release the pressing structure 340. The branch pipe 20 can then be reset and moved away from the heating head 320 by the elastic action of the elastic element 350. This makes it easier for the heating head 320 to perform the next operation of retracting back to the mounting base 310, avoiding the problem of structural interference. The operation is simple and convenient.

[0051] Optionally, the aforementioned elastic element 350 may be, but is not limited to, a spring.

[0052] Optionally, combined Figure 3 As shown, the base 100 has a platform 100a, and the track 200 is set on the platform 100a. The first direction X, the second direction Z, and the extension direction Y of the track 200 are arranged perpendicular to each other, and the second direction Z is perpendicular to the platform 100a. This allows the material pick-up head 330 to drive the branch pipe 20 to perform downward pressure and heat melting along the direction perpendicular to the platform 100a. Then, the branch pipe 20 can perform heat melting operation under the dual action of downward pressure and gravity. At this time, the directions of downward pressure and gravity are both set along the second direction Z, which reduces the influence of the force deviating from the second direction Z on the branch pipe 20 and improves the heat melting effect of the branch pipe 20.

[0053] Optionally, continue to combine Figure 3 As shown, the first limiting member 410 can be configured as a limiting seat, which is provided with a limiting gate 410a. The hot melt mechanism 300 is provided with a limiting gate 360, which is used to engage with the limiting gate 410a to limit the hot melt mechanism 300 on the track 200. In this way, each time the limiting gate 360 ​​engages with the limiting gate 410a, the hot melt mechanism 300 can be automatically fixed and the hot melt position of the hot melt mechanism 300 on the track 200 can be automatically positioned relative to the welding point of the main pipeline 10, thus improving the ease of operation.

[0054] Combination Figure 3As shown, the limiting seat may include a first limiting seat 411 and a second limiting seat 412 arranged in a direction perpendicular to the track 200. The limiting gate 360 ​​includes a first gate 361 and a second gate 362 arranged in a direction perpendicular to the track 200. The first gate 361 is used to engage with the first limiting seat 411, and the second gate 362 is used to engage with the second limiting seat 412. Thus, the setting of two limiting gates 360 and two limiting seats helps to improve the limiting effect on the hot melt mechanism 300.

[0055] Optionally, see Figure 1 and Figure 4 As shown, the second limiting component 500 may include a second limiting member 510 and a third limiting member 520. The second limiting member 510 and the third limiting member 520 are both spaced apart along a direction parallel to the track 200. The main pipeline 10 includes a main pipeline 11 and branch pipelines 12 spaced apart on the main pipeline 11. The second limiting member 510 is used to support the main pipeline 11, and the third limiting member 520 is used to support the branch pipelines 12.

[0056] Specifically, the second limiting member 510 is spaced apart along the extension direction of the main pipeline 11, thus providing multi-point support for the main pipeline 11 and improving its support effect. In addition, in this embodiment, the third limiting member 520 supports the branch pipeline 12, thus limiting the main pipeline 10 in the direction parallel to the extension direction Y of the track 200; the second limiting member 510 supports the branch pipeline 20, thus limiting the main pipeline 10 in the first direction X. Thus, through the combined use of the second limiting member 510 and the third limiting member 520, this embodiment can achieve horizontal limiting of the main pipeline 10, i.e., in the direction parallel to the platform 100a. Therefore, only the positional design relative to the first limiting component 400 needs to be considered, which can improve the accuracy of the welding point of the hot melt mechanism 300 on the main pipeline 10, thereby improving the welding effect and reducing welding dimensional errors.

[0057] Optionally, combined Figure 1 As shown, according to the above embodiments of this application, the welding apparatus 1 may further include a fixing mechanism 600, which is disposed on the base 100. The fixing mechanism 600 is used to fix the main pipe 10, thereby improving the fixing effect of the main pipe 10, reducing the shaking of the main pipe 10, and thus improving the welding effect. Understandably, according to the above embodiments of this application, the second limiting member 510 and the third limiting member 520 can serve as limiting members of the main pipe 10, and the fixing mechanism 600 serves as a fixing member of the main pipe 10. This can reduce the displacement or vibration of the main pipe 10 during the welding process, thereby helping to improve the welding effect.

[0058] Optionally, the aforementioned fixing mechanism 600 may be configured as a claw or caliper, etc.

[0059] Optionally, combined Figure 4 As shown, the fixing mechanism 600 includes a first clamping mechanism 610 and a second clamping mechanism 620. The first clamping mechanism 610 and the second clamping mechanism 620 are spaced apart along the arrangement direction of the second limiting member 510. The first clamping mechanism 610 and the second clamping mechanism 620 are used to clamp the main pipeline 11, thus forming a multi-point clamping effect on the main pipeline 11, thereby improving the fixing effect of the main pipeline 11.

[0060] Optionally, the fixing mechanism 600 may include an adjustment structure and a clamping structure. The clamping structure is used to clamp the main pipeline 11, and the adjustment mechanism is used to adjust the tightness of the clamping structure. In this way, the tightness of the clamping structure can be adjusted by adjusting the adjustment mechanism, which facilitates the loading and unloading operation of the main pipeline 10 on the second limit assembly 500.

[0061] For example, the clamping structure can be configured as two clamping blocks with threaded holes, and the adjusting structure can be configured as a lead screw, which can be inserted into the threaded holes of the two clamping blocks, and the threads of the two clamping blocks are arranged in opposite directions. Then, when the lead screw rotates forward and backward, it can drive the two clamping blocks to move closer or further away from each other, thereby realizing the clamping and tension adjustment of the main pipe 10.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
