Description

Technical Field

[0001] This application relates to the technical field of battery production equipment, and in particular to a battery tube connector welding device. Background Technology

[0002] Flow batteries are a novel electrochemical energy storage technology, belonging to the category of rechargeable batteries. A flow battery consists of a stack unit, electrolyte, electrolyte storage and supply unit, and management and control unit. Its core feature is the separate and independent circulation of the positive and negative electrolytes, giving flow batteries high capacity, wide applicability, environmental adaptability, and a long cycle life. Flow batteries achieve the interconversion of electrical and chemical energy through reversible redox reactions of the active materials in the positive and negative electrode electrolyte solutions. During charging, oxidation occurs at the positive electrode, increasing the valence state of the active materials, while reduction occurs at the negative electrode, decreasing the valence state; the discharge process is the reverse. The positive and negative electrode electrolyte solutions of a flow battery are stored in external tanks and transported to the battery interior via pumps and pipelines for the reaction.

[0003] Battery tube connectors are a crucial component of flow batteries, typically composed of a pipe flange welded to a connecting pipe. Currently, battery tube connector production still largely relies on manual welding, which is not only inefficient and unable to meet the production cycle of flow batteries, but also prone to misalignment errors between the pipe flange and the connecting pipe. This can lead to improper installation and use of the welded battery tube connector, resulting in a low yield rate. Utility Model Content

[0004] Therefore, it is necessary to provide a battery tube connector welding device to address the problems of low production efficiency and low yield.

[0005] This application discloses a battery tube connector welding device, which includes:

[0006] A pipe positioning mechanism, used for clamping and positioning connecting pipes;

[0007] A flange positioning mechanism includes a displacement module and a clamp connected to the displacement module in a driving manner. The clamp is disposed opposite to the pipe positioning mechanism at a distance. The clamp is used to clamp and position the pipe flange. The displacement module can drive the clamp to move closer to or away from the pipe positioning mechanism. A welding station is formed between the pipe positioning mechanism and the clamp.

[0008] A welding processing mechanism includes a welding power module and a welding execution head that is driven by the welding power module. The welding power module drives the welding execution head to enter or exit the welding station. When the welding execution head enters the welding station, it performs hot-melt processing on the pipe flange and the connecting pipe. When the welding execution head completes the hot-melt processing and exits the welding station, the shifting module drives the clamp to move closer to the pipe positioning mechanism so that the pipe flange and the connecting pipe are bonded and fixed.

[0009] When the battery tube connector welding device using this solution is in operation, the pipe flange is first clamped to the pipe positioning mechanism and the connecting pipe is clamped to the fixture by manual or automatic feeding equipment, respectively, to achieve initial positioning of the pipe flange and the connecting pipe at a distance. Next, the welding processing mechanism is activated, and the welding power module drives the welding actuator head to move from the outside into the welding station. At this time, the welding actuator head is located between the pipe flange and the connecting pipe, and is simultaneously energized to generate high temperature. Then, the displacement module drives the fixture to move the pipe flange closer to the connecting pipe, ensuring tight contact between the pipe flange, the welding actuator head, and the connecting pipe. The high-temperature welding actuator performs heat fusion treatment on the contact ends of the pipe flange and the connecting pipe. After the heat fusion treatment has been completed for a preset time, the welding power module drives the welding actuator to withdraw from the welding station. Then, the displacement module drives the pipe flange and the connecting pipe to approach and press them together directly. The heat fusion parts of the two are bonded together, thus completing the automatic welding assembly of the pipe flange and the connecting pipe. Compared with the existing technology, the welding process does not require human intervention, has a high degree of automation, and can significantly improve production efficiency. At the same time, it eliminates the misalignment of the pipe flange and the connecting pipe, ensures the welding quality of the pipe flange and the connecting pipe, and thus improves the yield rate.

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.

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] See Figures 1 to 4 This application presents a battery tube connector welding device 100, which includes a movable base 50, a pipe positioning mechanism 10, a flange positioning mechanism 20, and a welding processing mechanism 40.

[0036] The mobile base 50 includes a machine base and casters mounted on the bottom of the machine base, so that the battery tube connector welding device 100 has the ability to move and can flexibly change the working location.

[0037] The pipe positioning mechanism 10, the flange positioning mechanism 20, and the welding processing mechanism 40 are respectively installed on the machine base of the movable base 50, which improves the integration of the whole machine and reduces space occupation.

[0038] The pipe positioning mechanism 10 is used to clamp and position the connecting pipe 200; the flange positioning mechanism 20 includes a displacement module 21 and a clamp 22 that is drivenly connected to the displacement module 21. The clamp 22 is disposed opposite to the pipe positioning mechanism 10 at a distance. The clamp 22 is used to clamp and position the pipe flange 300. The displacement module 21 can drive the clamp 22 to move closer to or away from the pipe positioning mechanism 10; a welding station 30 is formed between the pipe positioning mechanism 10 and the clamp 22; the welding processing mechanism 40 includes a welding power module 41. The welding execution head 42 is connected to the welding power module 41 for transmission. The welding power module 41 is used to drive the welding execution head 42 to enter or exit the welding station 30. When the welding execution head 42 enters the welding station 30, the welding execution head 42 performs hot melt processing on the pipe flange 300 and the connecting pipe 200 respectively. When the welding execution head 42 completes the hot melt processing and exits the welding station 30, the shifting module 21 drives the clamp 22 to move closer to the pipe positioning mechanism 10 so that the pipe flange 300 and the connecting pipe 200 are bonded and fixed.

[0039] Please combine Figure 5 For example, the pipe flange 300 and the connecting pipe 200 can be made of any material such as metal or plastic, and both can be circular, square, or other structural shapes. The specific choice can be made flexibly according to actual needs.

[0040] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: When the battery tube connector welding device 100 of this solution is working, firstly, the pipe flange 300 is clamped to the pipe positioning mechanism 10 and the connecting pipe 200 is clamped to the fixture 22 by manual or automatic feeding equipment, so as to initially position the pipe flange 300 and the connecting pipe 200 at a distance; then, the welding processing mechanism 40 is started, and the welding power module 41 drives the welding execution head 42 to move from the outside into the welding station 30. At this time, the welding execution head 42 is located between the pipe flange 300 and the connecting pipe 200, and at the same time, the welding execution head 42 is energized to generate high temperature; then, the shifting module 21 drives the fixture 22 to move the pipe flange 300 closer to the connecting pipe 200, so that the pipe flange 300 and the welding execution head 42 are positioned at a distance. The welding head 42 and the connecting pipe 200 are in close contact. The high-temperature welding head 42 performs heat fusion treatment on the contact ends of the pipe flange 300 and the connecting pipe 200 respectively. After the preset heat fusion treatment time, the welding power module 41 drives the welding head 42 to withdraw from the welding station 30. However, the shifting module 21 drives the pipe flange 300 and the connecting pipe 200 to approach and directly press them together. The heat fusion parts of the two are bonded together, thereby completing the automatic welding assembly of the pipe flange 300 and the connecting pipe 200. Compared with the existing technology, the welding process does not require human intervention, has a high degree of automation, and can significantly improve production efficiency. At the same time, it eliminates the deviation in the docking position of the pipe flange 300 and the connecting pipe 200, ensures the welding quality of the pipe flange 300 and the connecting pipe 200, and thus improves the yield rate.

[0041] Please continue reading. Figures 2 to 4 In one embodiment, the pipe positioning mechanism 10 includes a base plate 11 and a positioning block 12. The positioning block 12 is mounted on the side of the base plate 11 facing the clamp 22. The positioning block 12 has a positioning groove 121. The side wall of the positioning groove 121 protrudes towards the center of the groove and is provided with a limiting stop 122. The limiting stop 122 is used to press against the connecting pipe 200 to constrain the degree of freedom of the connecting pipe 200 in the vertical direction.

[0042] The base plate 11 is fixed to the machine surface by means of screwing, snap-fitting, etc. The connecting pipe 200 is pushed into the positioning groove 121 in the horizontal direction. The end plate of the connecting pipe 200 is just inserted into the lower part of the limiting stop 122, so that the limiting stop 122 can press the end plate to restrict the vertical degree of freedom of the connecting pipe 200. This positioning method is simple. After the connecting pipe 200 is welded and fixed to the pipe flange 300, it can be pulled out from the positioning groove 121 in the horizontal direction. The disassembly operation is convenient and labor-saving.

[0043] As is easy to understand, after the connecting pipe 200 is clamped, it is in an upright position. The other end of the connecting pipe 200 away from its end plate faces the pipe flange 300, which is the end used for heat fusion welding with the pipe flange 300.

[0044] Please continue reading. Figure 4 Furthermore, the side wall of the positioning groove 121 is also provided with a stop protrusion 123, which is used to engage with the connecting pipe 200 to constrain the degree of freedom of the connecting pipe 200 in the horizontal direction.

[0045] To prevent the connecting pipe 200 from shifting horizontally within the positioning groove 121, the connecting pipe 200 will slightly interfere with the stop protrusion 123 during the process of being pushed into the positioning groove 121, until it passes the stop protrusion 123 and is fully installed in the positioning groove 121. At this time, the stop protrusion 123 abuts against the outer wall of the connecting pipe 200, thereby restricting the horizontal degree of freedom of the connecting pipe 200 and improving the clamping stability of the connecting pipe 200.

[0046] Optionally, the stop protrusion 123 is a spherical protrusion, which helps to reduce the scratching force on the connecting pipe 200 and avoid damage to the connecting pipe 200.

[0047] Please continue reading. Figures 2 to 4 In another embodiment, the shifting module 21 includes a stand 211 and a lifting driver 212. The stand 211 is arranged on one side of the pipe positioning mechanism 10. The lifting driver 212 is connected to the clamp 22 in a transmission manner. The lifting driver 212 is disposed at the upper end of the stand 211 so that the clamp 22 is located above the pipe positioning mechanism 10. When the clamp 22 descends, it approaches the pipe positioning mechanism 10. When the clamp 22 rises, it moves away from the pipe positioning mechanism 10.

[0048] The support frame 211 has a rectangular structure and is installed vertically on the surface of the machine base, with the length of the support frame 211 being set along the height direction.

[0049] The support frame 211 positions the lifting drive 212 and the clamp 22 above the pipe positioning mechanism 10, so that the flange positioning mechanism 20 and the pipe positioning mechanism 10 are arranged in the vertical direction, making full use of the vertical space and reducing the lateral space occupation. In addition, the pipe flange 300 can be aligned with the connecting pipe 200 in the vertical direction, which can avoid displacement and misalignment under its own weight.

[0050] For example, the lifting driver 212 can be one of the following: a cylinder, an electric actuator, or a linear motor. The appropriate type can be selected based on actual needs.

[0051] More specifically, in the above embodiment, the support frame 211 includes a fixed carrier plate 211a, a movable carrier plate 211b, and a guide post 211c. The lifting driver 212 is mounted on the fixed carrier plate 211a, and the telescopic driving end of the lifting driver 212 is connected to the movable carrier plate 211b. The fixed carrier plate 211a has a guide hole, the guide post 211c is mounted on the movable carrier plate 211b and slidably passes through the guide hole, and the clamp 22 is disposed on the movable carrier plate 211b.

[0052] During the hot melt process, the lifting driver 212 drives the movable carrier plate 211b to descend, thereby bringing the clamp 22 and the pipe flange 300 closer to the welding execution head 42. During this process, the guide column 211c slides in the guide hole, which guides and limits the descent of the movable carrier plate 211b, the clamp 22 and the pipe flange 300, ensuring that the pipe flange 300 can accurately dock with the welding execution head 42.

[0053] In addition, after the welding actuator 42 completes the heat fusion treatment of the pipe flange 300 and the connecting pipe 200, the welding actuator 42 moves out of the welding station 30. Under the guidance of the guide column 211c, the heat-melting end of the descending pipe flange 300 can also accurately join with the heat-melting end of the connecting pipe 200, and then solidify and bond together after cooling, realizing the welding assembly of the battery tube joint.

[0054] It is easy to understand that the pipe flange 300 produces a circular pipe end for heat fusion, and the connecting pipe 200 produces a circular pipe section for heat fusion. Furthermore, the dimensions of the two pipe ends are the same or close to each other, so that a sufficiently large joint area can be formed between them, thereby improving the welding strength and sealing reliability.

[0055] Please continue reading. Figure 4 In one embodiment, the clamp 22 includes a clamp body 221, an annular retaining plate 222, and a snap-fit ​​post 223. The annular retaining plate 222 is disposed on the clamp body 221, and the snap-fit ​​post 223 is disposed on the clamp body 221 and located inside the annular retaining plate 222. The clamp body 221 is used to connect with the movable carrier plate 211b, and the connection method can be, but is not limited to, at least one of screw connection, snap-fit ​​connection, magnetic connection, and adhesive connection.

[0056] The end of the pipe flange 300 away from the connecting pipe 200 has a through hole and an annular groove arranged coaxially around the through hole. After aligning the annular groove of the pipe flange 300 with the annular clamping plate 222 and aligning the through hole with the clamping post 223, the pipe flange 300 is inserted and assembled. With the limiting and fastening force of the two sets of insertion structures, the pipe flange 300 can be firmly installed on the clamp 22 and is not easy to loosen.

[0057] However, it should be noted that after the pipe flange 300 is welded and fixed to the connecting pipe 200, due to the limiting constraint of the pipe positioning mechanism 10, when the lifting drive 212 drives the clamp 22 to rise away from the pipe positioning mechanism 10, the pipe flange 300 can be smoothly separated from the clamp 22. Then, the connecting pipe 200 can be pulled out horizontally, and the welded battery tube connector can be taken out from the pipe positioning mechanism 10.

[0058] Please continue reading. Figures 2 to 4 In addition, based on any of the above embodiments, the welding power module 41 includes a power base 411, a power source 412 and a transmission unit. The power source 412 is connected to the transmission unit, so that the transmission unit is reciprocally slidably disposed on the power base 411, and the welding execution head 42 is connected to the transmission unit.

[0059] The power base 411 is installed on the surface of the machine tool. The installation method can be any one of screw connection, snap connection, magnetic connection, adhesive connection, etc., and you can choose flexibly according to actual needs.

[0060] The power source 412 is installed on the power base 411 and located on the same side of the pipe positioning mechanism 10 and the flange positioning mechanism 20, so that the power source 412 can drive the transmission unit to output horizontal reciprocating linear power, thereby driving the welding execution head 42 to enter or exit the welding station 30. The driving method is simple, the implementation cost is low, and the reliability is high.

[0061] More specifically, the transmission unit includes a slide rail 413, a slider 414, and a sliding seat. The slide rail 413 is mounted on the power base 411. The slider 414 is slidably mounted on the slide rail 413 and connected to the sliding seat. The sliding seat is connected to the welding execution head 42. By means of the slider 414 reciprocating on the slide rail 413, the welding execution head 42 can be guided, so that the welding execution head 42 can enter or exit the welding station 30 more accurately and stably.

[0062] In an optional embodiment, the sliding seat includes a fixed block 415, an elastic floating element 416, and a movable block 417. The fixed block 415 is connected to the slider 414, and the movable block 417 is connected to the fixed block 415 via the elastic floating element 416. The welding execution head 42 is disposed on the movable block 417. When the welding execution head 42 enters the welding station 30 and accurately stops between the connecting pipe 200 and the pipe flange 300, the lifting driver 212 drives the pipe flange 300 to descend. An instantaneous impact force is generated between the pipe flange 300, the welding head 422, and the connecting pipe 200. The elastic floating element 416 contracts and deforms (as the movable block 417 and the fixed block 415 move closer and float), thereby offsetting the impact force and reducing the collision force between the pipe flange 300, the welding head 422, and the connecting pipe 200. This prevents excessive deformation of the pipe end of the pipe flange 300 and the connecting pipe 200 caused by heat fusion, which would affect the forming quality of the pipe joint after welding.

[0063] Furthermore, the welding execution head 42 includes a power receiving plate 421 and a welding head 422. One end of the power receiving plate 421 is disposed on the movable block 417, and the other end of the power receiving plate 421 extends outside the movable block 417 to form a cantilever structure. The power receiving plate 421 is used for electrical connection with a power supply cable, and the welding head 422 is disposed on the power receiving plate 421. By installing the welding head 422 on the cantilever end of the power receiving plate 421, the welding head 422 has a sufficiently large stroke length, so that when the welding head 422 enters the welding station 30, collision interference between the sliding seat and the pipe positioning mechanism 10 is avoided.

[0064] The power receiving plate 421 is electrically connected to the power supply via a cable, thereby supplying electrical energy to the welding head 422. This generates high temperatures after power is applied, enabling heat fusion processing of the pipe flange 300 and the pipe end of the connecting pipe 200.

[0065] 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.

[0066] 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.
