Description

Technical Field

[0001] This application relates to the field of hydrogen production by water electrolysis, and in particular to an electrolysis cell welding device. Background Technology

[0002] Hydrogen energy, as a clean energy source, is receiving increasing attention for its development and production. Alkaline water electrolysis is a common method for hydrogen production. Currently, in traditional hydrogen production equipment, the electrodes and diffusion layer are connected by compression. However, as the equipment operates for longer periods, oxidation easily occurs on the contact surfaces between the electrodes and the diffusion layer, leading to increased contact resistance and decreased hydrogen production efficiency. Summary of the Invention

[0003] This application provides an electrolytic cell welding device to improve the connection quality between the electrodes and the diffusion layer of the electrolytic cell and reduce the problem of decreased electrolysis efficiency due to increased contact resistance.

[0004] This application provides an electrolytic cell welding apparatus, including,

[0005] frame;

[0006] The first pole is mounted on the frame;

[0007] The second electrode section is disposed on the frame. The second electrode section is a plate-shaped structure used to place the electrode to be welded and the diffusion layer.

[0008] The welding power source has a first electrode and a second electrode that are connected to the positive and negative electrodes of the welding power source in a one-to-one correspondence. The first electrode and the second electrode cooperate to press against the electrode and the diffusion layer to form a power circuit.

[0009] An adjustment system is used to adjust the relative positions of the first electrode and the second electrode, wherein the first electrode moves relative to the second electrode in the X, Y, and Z directions; wherein...

[0010] The X and Y directions are both parallel to the plane containing the second pole and perpendicular to each other, while the Z direction is perpendicular to the plane containing the second pole.

[0011] In the above technical solution, the electrode and diffusion layer to be connected are clamped by the first electrode and the second electrode, and welding is achieved at the clamping position. At the same time, the position of the first electrode relative to the second electrode can be adjusted by the adjustment system, and the welding connection between the electrode and the diffusion layer can be completed according to the connection requirements. The connection operation is relatively convenient. Compared with the current situation where the electrode and the diffusion layer are connected by contact, the problem of increased contact resistance caused by corrosion of the interface between the electrode and the diffusion layer is reduced, thereby improving the electrolysis efficiency of the corresponding electrolytic cell equipment.

[0012] In one specific implementation, the adjustment system includes a first adjustment component, the first adjustment component including,

[0013] A fixing plate is fixedly connected to the frame;

[0014] The mounting plate is slidably connected to the fixing plate along the X direction;

[0015] The first power component drives the mounting plate to slide relative to the fixed plate and locks the mounting plate relative to the fixed plate;

[0016] The mounting block is slidably connected to the mounting plate along the Z direction, and the first pole is disposed on the mounting block;

[0017] The second power component drives the mounting block to slide relative to the mounting plate and locks the mounting block relative to the mounting plate.

[0018] In the above technical solution, the first power component and the second power component can be set to make it easier to adjust the first pole in the X and Z directions, thereby improving the convenience of the welding process.

[0019] In one specific implementation, the first pole portion is circular and rotatably connected to the mounting block.

[0020] The first electrode and the diffusion layer to be welded are in a rolling fit. This allows for welding operations at different positions of the diffusion layer, and compared to a sliding fit, it is less likely to cause wear or displacement of the diffusion layer.

[0021] In one specific implementation, a cooling component is further included on the mounting block for cooling the first electrode portion.

[0022] By using a cooling system to cool the first electrode section, the high temperature of the first electrode section caused by continuous welding operations is reduced, thereby improving work efficiency and the stability of the welding operation.

[0023] In one specific implementation, the refrigeration assembly includes a cooling block fixedly connected to the mounting block, the cooling block having a cavity for introducing a cooling medium;

[0024] The vertical projection of the cooling block onto the plane containing the first pole is located inside the first pole.

[0025] Maximize the heat exchange efficiency between the cooling block and the first electrode to improve the cooling efficiency of the first electrode and achieve a better cooling effect.

[0026] In one specific implementation, a clamping assembly for clamping the electrode and the diffusion layer is also included, the clamping assembly comprising,

[0027] A clamping plate is located on the side of the second pole facing the first pole and is slidably connected to the frame along the Z direction.

[0028] A clamping element is fixedly connected to the frame and is used to drive the clamping plate to slide relative to the frame and lock the clamping plate.

[0029] By setting up a clamping component to press the diffusion layer, the electrode to be welded and the diffusion layer remain in a stable position during the welding process, reducing the problem of electrode and diffusion layer misalignment, improving the stability of the welding operation, and improving the welding quality.

[0030] In one specific implementation, the clamping assembly further includes a toothed plate, the toothed plate being fixedly connected to the surface of the clamping plate facing the second pole.

[0031] The surface of the toothed plate facing the second pole has a toothed structure, and the toothed structure on the toothed plate is adapted to the structure of the diffusion layer.

[0032] A toothed plate is designed to accommodate the structural adaptability of the diffusion layer itself. When the diffusion layer and the electrode are positioned by pressing the diffusion layer, the problem of the diffusion layer being squeezed and deformed is not easily caused, thus providing a certain degree of protection for the diffusion layer.

[0033] In one specific implementation, there are two clamping plates, both of which are slidably connected to the frame along the Z direction, and a gap is provided between the two clamping plates for the first pole to pass through.

[0034] The first electrode section passes between two clamping plates and presses against the diffusion layer. That is, during the welding operation, the two clamping plates are located on both sides of the first electrode section's movement path along the X direction, which provides a better clamping and positioning effect on the diffusion layer and the electrode.

[0035] In one specific implementation, the adjustment system further includes a second adjustment component, the second adjustment component including a support plate slidably connected to the frame along the Y direction and a drive component disposed on the frame;

[0036] The driving component drives the support plate to slide relative to the frame and locks the support plate;

[0037] The second pole is fixedly connected to the support plate.

[0038] It is easier to move the second electrode along the Y direction, thus improving the convenience of welding operations.

[0039] In one specific implementation, the system further includes a positioning component for defining the positions of the electrode and the diffusion layer, the positioning component comprising,

[0040] A positioning plate slides relative to the bearing plate along the Z direction. Positioning teeth are fixedly connected to the positioning plate. The positioning teeth are used to adapt to the toothed structure of the diffusion layer.

[0041] A positioning element is used to drive the positioning plate to slide and lock the positioning plate.

[0042] By placing the electrode and diffusion layer on the second electrode and fixing them with positioning components, it is less likely that the electrode and diffusion layer will shift during the welding process and when the carrier plate moves the second electrode. This improves the stability of the electrode and diffusion layer on the second electrode and facilitates subsequent welding of the two.

[0043] In one specific implementation, the positioning component further includes,

[0044] A sliding table is slidably connected to the support plate along the X or Y direction;

[0045] A sliding element is fixedly connected to the support plate, which drives the sliding platform to slide relative to the support plate and locks the sliding platform.

[0046] The positioning plate is slidably connected to the sliding table.

[0047] In the above technical solution, the positioning plate is placed on the sliding stage, which can drive the positioning plate to move closer to or away from the placement position of the upper electrode and the diffusion layer of the second electrode part along the X or Y direction. While realizing the positioning of the electrode and the diffusion layer, the positioning plate is adjusted away from the corresponding placement position during the picking and placing of the electrode and the diffusion layer, which is convenient for picking and placing. Moreover, during the picking and placing process, it is not easy for the electrode and the diffusion layer to rub against the positioning plate, causing damage to the electrode and the diffusion layer.

[0048] In one specific implementation scheme, a plurality of anti-warping components are further included, wherein the plurality of anti-warping components are disposed around the electrode and spaced apart from the diffusion layer; the anti-warping components include

[0049] The mounting platform is slidably connected to the support plate along the Z direction;

[0050] An adjusting component is fixedly connected to the support plate, which drives the mounting platform to slide relative to the support plate and locks the mounting platform.

[0051] An anti-tilting rod is provided on the mounting platform for abutting against the surface of the diffusion layer away from the second electrode.

[0052] By using anti-warping components to press the edges of the electrode and the diffusion layer together, the warping of the electrode and the diffusion layer edges is reduced, ensuring smooth subsequent welding operations.

[0053] In one specific implementation, the anti-tilting rod is rotatably connected to the mounting platform;

[0054] The anti-tilting assembly also includes a rotating component fixedly connected to the mounting platform. The rotating component is used to drive the anti-tilting rod to rotate relative to the mounting platform and lock the anti-tilting rod.

[0055] The rotation axis of the anti-tilting rod is parallel to the Z direction.

[0056] In addition to pressing the electrode and diffusion layer together with the anti-pry bar, the position of the anti-pry bar is adjusted when picking up and putting down the electrode and diffusion layer to reduce interference with the normal picking up and putting down of the electrode and diffusion layer, and to prevent the electrode and diffusion layer from being scratched and damaged.

[0057] In one specific implementation, the mounting platform is located on the side of the support plate opposite to the second pole portion;

[0058] Both the support plate and the second pole are provided with through holes for the movement of the anti-tilting rod.

[0059] By placing the above structure on the side of the support plate away from the second electrode, the space occupied by the electrodes and diffusion layer on the second electrode can be reduced. Furthermore, when the second electrode needs to be installed or removed later, it can be less affected by the anti-tilting component, making the operation easier.

[0060] In one specific implementation, the welding power source includes a power supply body and a power host connected to the power supply body via a signal, wherein the power host controls the power supply body to supply power at multiple preset frequencies.

[0061] In the above technical solution, the power supply frequency can be easily controlled by the welding power source. During actual welding, it can be adjusted as needed to improve the applicability of the welding equipment and achieve better welding results. Attached Figure Description

[0073] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become clearer and more apparent.

[0074] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0075] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0076] To facilitate understanding of the electrolytic cell welding equipment provided in this application embodiment, the application scenario of this electrolytic cell welding equipment is first introduced. The electrolytic cell welding equipment provided in this application embodiment is used in the production of equipment for alkaline water electrolysis to produce hydrogen, connecting the electrodes and diffusion layer of the electrolytic cell. In the currently used electrolytic cell structure, the electrodes and diffusion layer are in abutting configuration, working in a tightly pressed state. However, with prolonged electrolysis time, corrosion and rust on the contact surfaces of the electrodes and diffusion layer can easily lead to increased contact resistance, resulting in decreased electrolysis efficiency. This application embodiment provides an electrolytic cell welding equipment for connecting the electrodes and diffusion layer, reducing the phenomenon of increased contact resistance between the electrodes and diffusion layer and improving electrolysis efficiency. A detailed description is provided below with reference to the specific accompanying drawings and embodiments.

[0077] For ease of description, the "electrolytic cell welding equipment" in this application embodiment will be referred to as "welding equipment".

[0078] refer to Figure 1 , Figure 1 A schematic diagram of the welding equipment provided in this application embodiment is shown. The welding equipment provided in this application embodiment includes a frame 1, a first electrode 11, a second electrode 12, and a welding power source 13. The frame 1 serves as the base of the entire equipment, and its specific structure can be adapted or adjusted according to the installation components. The first electrode 11 and the second electrode 12 are both disposed on the frame 1. The first electrode 11 is electrically connected to the positive electrode of the welding power source 13, and the second electrode 12 is electrically connected to the negative electrode of the welding power source 13. The second electrode 12 has a plate-like structure. The electrode to be connected and the diffusion layer are laid on the second electrode 12. The first electrode 11 and the second electrode 12 cooperate to press against the electrode and the diffusion layer to form a power-conducting circuit.

[0079] In the formed energized circuit, the resistance between the first electrode 11 and the second electrode 12 is relatively high, generating significant heat. This heat is used to weld the electrode to the diffusion layer. Of course, in other embodiments, the first electrode 11 can be electrically connected to the negative terminal of the welding power source 13, and the second electrode 12 can be electrically connected to the positive terminal of the welding power source 13. In this embodiment, only the example of the first electrode 11 being electrically connected to the positive terminal and the second electrode 12 being electrically connected to the negative terminal is used for illustration.

[0080] In addition, the welding equipment also includes an adjustment system to adjust the relative position of the first electrode 11 and the second electrode 12. Specifically, the first electrode 11 moves relative to the second electrode 12 in the X, Y, and Z directions, thereby enabling welding at different positions.

[0081] For example, refer to Figure 1The X and Y directions are both parallel to the plane where the second pole part 12 is located, and the X direction is perpendicular to the Y direction, while the Z direction is perpendicular to the plane where the second pole part 12 is located.

[0082] By welding the electrodes to the diffusion layer, the problem of increased contact resistance due to corrosion of the contact surfaces of the electrodes and diffusion layer as electrolysis time increases can be reduced, thereby improving the stability of the electrolytic cell and increasing electrolysis efficiency. During welding, the adjustment system can be used to adjust the relative positions of the first electrode 11 and the second electrode 12, enabling connections at different locations between the electrodes and the diffusion layer, making it convenient to use.

[0083] To ensure smooth welding and reduce damage, the first electrode 11 and the second electrode 12 are made of materials with good conductivity and wear resistance. For example, beryllium copper alloy, tungsten copper alloy, conductive fiber, etc. can be used. Of course, in other embodiments, other materials with high conductivity and high wear resistance can also be used, which does not limit the scope of protection of the embodiments of this application.

[0084] Specifically, the first electrode portion 11 and the second electrode portion 12 are in point contact, which allows for convenient adjustment of the connection position between the electrode and the diffusion layer, improving applicability. In actual operation, adjustments can be made as needed. It should be understood that the point contact referred to in this embodiment is not necessarily a single point, but rather illustrates that the area where the first electrode portion 11 and the second electrode portion 12 meet the electrode and the diffusion layer is small. Therefore, when welding the electrode and the diffusion layer, multiple "points" are welded sequentially to achieve the overall welding operation.

[0085] The welding power supply 13, which supplies power for welding operations, includes a power supply body and a power supply main unit. The power supply body provides power and can supply power at different frequencies. The power supply main unit is connected to the power supply body, and the output frequency of the power supply body is adjusted so that the power supply body can supply power at various different set frequencies. The specific value of the set frequency is set according to the actual operation needs and can be determined by those skilled in the art based on existing knowledge. Therefore, the determination of the set frequency will not be described in detail in this embodiment.

[0086] When welding electrodes and diffusion layers, the appropriate power supply frequency can be selected according to the type of electrode to be welded, the type of diffusion layer, and the desired effect. This allows for specific types of welding operations to be performed as needed, making it easier to meet welding requirements and improve welding quality.

[0087] Reference Figure 2 and in conjunction with reference Figure 1The adjustment system includes a first adjustment component 2 and a second adjustment component 3. The first adjustment component 2 is used to adjust the position of the first pole 11 and drive the first pole 11 to move relative to the frame 1 in the X and Z directions. The second adjustment component 3 is used to adjust the second pole 12 to move relative to the frame 1 in the Y direction.

[0088] Reference Figure 2 as well as Figure 3 The first adjustment component 2 includes a fixed plate 21, a mounting plate 22, a first power component 23, a mounting block 24, and a second power component 25. The fixed plate 21 is fixedly connected to the frame 1, and the mounting plate 22 is slidably connected to the fixed plate 21 in the X direction. The first power component 23 is disposed on the fixed plate 21 and is used to drive the mounting plate 22 to slide relative to the fixed plate 21 and lock the position of the mounting plate 22.

[0089] For example, the mounting plate 22 and the fixed plate 21 are connected by a guide rail and slider, wherein the guide rail is fixedly connected to the fixed plate 21, and the slider is fixedly connected to the mounting plate 22, thereby achieving a sliding connection between the mounting plate 22 and the fixed plate 21. The first power component 23 is a cylinder that extends along the X direction, driving the mounting plate 22 to slide along the X direction and can be locked relative to the fixed plate 21. In other embodiments, the first power component 23 can also be a common driving structure such as a lead screw and slider structure or an electrode-driven conveyor belt structure, as long as it can drive the mounting plate 22 to slide.

[0090] Mounting block 24 and mounting plate 22 are slidably connected along the Z-direction. A first pole 11 is mounted on mounting block 24. A second power component 25 is mounted on mounting plate 22, driving mounting block 24 to slide relative to mounting plate 22 and locking the position of mounting block 24. The connection method between mounting block 24 and mounting plate 22 is similar to the connection structure between mounting plate 22 and fixed plate 21, using a guide rail slider connection, which will not be elaborated further here. The second power component 25 is a cylinder, fixedly connected to mounting plate 22. The piston rod is connected to mounting block 24, driving mounting block 24 to slide relative to mounting plate 22 along the Z-direction and locking it relative to mounting plate 22.

[0091] Of course, in other embodiments, the structure of the second power member 25 can also refer to the structure of the first power member 23 and be driven in a manner known to those skilled in the art.

[0092] The first adjustment component 2 allows for convenient adjustment of the first pole 11 relative to the frame 1 in the X and Z directions, and the first pole 11 can be locked in any position within the travel range, making it convenient to use.

[0093] Reference Figure 4The second adjustment component 3 includes a support plate 31 slidably connected to the frame 1 and a drive component 32 fixedly connected to the frame 1. The support plate 31 slides relative to the frame 1 in the Y direction. The specific sliding method can refer to the structure in which the mounting plate 22 is slidably connected to the fixed plate 21 and the mounting block 24 is slidably connected to the mounting plate 22. Correspondingly, the drive component 32 is connected to the support plate 31, driving the support plate 31 to slide relative to the frame 1 and lock relative to the frame 1. For example, the drive component 32 is an electrode conveyor belt structure.

[0094] By setting the first adjustment component 2 and the second adjustment component 3, the position of the first electrode 11 relative to the second electrode 12 in three-dimensional space can be adjusted. In actual welding operations, it is more convenient to adjust the position of the first electrode 11 according to welding needs.

[0095] Reference Figure 5 To facilitate easier adjustment of the relative positions of the first electrode 11 and the second electrode 12, the welding equipment also includes a controller 4. The controller 4 is signal-connected to the first power component 23, the second power component 25, and the drive component 32 to adjust the movement of the mounting plate 22, the mounting block 24, and the support plate 31. In practical applications, the controller 4 is integrated into the computer host, allowing manual input of corresponding adjustment parameters through the operating interface to achieve specific adjustments to the movements of each component. Furthermore, it can correct deviations in component movements by adjusting the first power component 23, the second power component 25, and the drive component 32; or control the corresponding component movements according to a pre-set program; thus enabling convenient control of the corresponding components.

[0096] Reference Figure 3 The first electrode 11 is a circular plate-shaped structure made of metal, and is rotatably connected to the mounting block 24. During welding, the second power component 25 drives the first electrode 11 to move toward the second electrode 12, so that the first electrode 11 presses against the diffusion layer and the electrode. Then, the first power component 23 drives the mounting plate 22 to slide in the X direction, and the first electrode 11 rolls in the X direction to achieve continuous electric welding.

[0097] It is also noted that during the continuous welding process, the first electrode 11 itself generates heat. Due to the limited size of the first electrode 11, the generated heat is difficult to dissipate in time, causing the temperature of the first electrode 11 to rise, affecting the normal welding process and reducing the welding quality. Therefore, referring to Figure 3 The welding equipment includes a cooling component 5 for cooling the first electrode 11. The cooling component 5 includes a cooling block 51 fixedly connected to the mounting block 24. The cooling block 51 has a cavity for introducing a cooling medium.

[0098] In addition, refer to Figure 5The refrigeration assembly 5 also includes a refrigeration component 52 for introducing a cooling medium into the cavity of the cooling block 51. For example, the refrigeration component 52 includes a storage tank for storing the cooling medium and a conveying component for introducing the cooling medium into the cavity.

[0099] In actual use, the cooling medium after passing through cooling block 51 will be returned to the refrigerator or a specific container for recycling, and reused after cooling, or replenished with new cooling medium.

[0100] The cooling component 5 is used to cool the first electrode 11, so that the temperature of the first electrode 11 is kept below 40°C during the welding process. This reduces the problem of the first electrode 11 overheating and getting stuck, and wears out quickly, thereby improving the stability and smoothness of the welding process and providing a certain degree of protection for the first electrode 11.

[0101] To achieve better cooling effect, the cooling assembly 5 also includes a temperature sensor 53 for detecting the temperature of the first electrode 11. The temperature sensor 53 is connected to the controller 4, and the controller 4 is also connected to the cooling component 52 to adjust the rate at which the cooling medium is introduced into the cavity of the cooling block 51, that is, to adjust the efficiency of cooling the first electrode 11.

[0102] For example, after welding begins, the temperature of the first electrode 11 detected by the temperature sensor 53 is below 40°C, and the cooling component 52 is in standby mode. As the welding operation continues, the temperature of the first electrode 11 continues to rise. When the temperature of the first electrode 11 detected by the temperature sensor 53 is above 40°C, the controller 4 controls the cooling component 52 to work, and introduces a cooling medium into the cooling block 51 to cool the first electrode 11, so that the temperature of the first electrode 11 is below 40°C.

[0103] During the temperature adjustment of the first electrode 11, the temperature of the first electrode 11 should be maintained within a certain range below 40°C, so that the temperature of the first electrode 11 is dynamically balanced within this range. For example, the temperature of the first electrode 11 is maintained between 38°C and 40°C. This range is only illustrative; in actual operation, the range is adjusted according to the material adaptability of the first electrode 11, its optimal operating temperature, and energy-saving factors. Compared to immediately shutting off the cooling element 52 once the temperature of the first electrode 11 drops below 40°C, this reduces frequent temperature fluctuations around 40°C, resulting in better cooling performance.

[0104] Specifically, refer to Figure 3A notch is provided on the mounting block 24, and the first electrode 11 is located inside the notch. The cooling block 51 is fixedly connected to the surface of the mounting block 24. The vertical projection of the cooling block 51 on the plane where the first electrode 11 is located is located inside the first electrode 11, and the cooling of the first electrode 11 is achieved through the conduction of the mounting block 24.

[0105] During the welding process, to ensure a good welding effect, it is necessary to maintain the stable position of the electrode and the diffusion layer, so as to reduce the problem of misalignment or displacement of the electrode and the diffusion layer during welding. (Refer to...) Figure 4 The welding equipment also includes a positioning component 6 for positioning the electrode and the diffusion layer, so that the electrode and the diffusion layer are located at a predetermined position on the second electrode portion 12, thereby reducing the occurrence of the electrode and the diffusion layer being offset relative to the second electrode portion 12.

[0106] Specifically, refer to Figure 6 and combined Figure 4 There are two positioning components 6, which are respectively disposed on two opposite sides of the support plate 31 in the X direction. The positioning component 6 includes a sliding stage 61, a slider 62, a positioning plate 63, and a positioning element 64. The sliding stage 61 is slidably connected to the support plate 31 in the X direction. For example, a base plate is fixedly connected to the support plate 31, and the sliding stage 61 is slidably connected to the base plate through a guide rail slider structure. The slider 62 is fixedly connected to the base plate and connected to the sliding stage 61, which drives the sliding stage 61 to slide in the X direction and locks the position of the sliding stage 61.

[0107] The positioning plate 63 slides relative to the sliding table 61 in the Z direction, and the positioning element 64 is fixedly connected to the sliding table 61. For example, the positioning element 64 is a cylinder, and the piston rod of the cylinder extends and retracts in the Z direction. The positioning plate 63 is fixedly connected to the piston rod of the cylinder, so that the positioning plate 63 slides relative to the bearing plate 31 in the Z direction. In order to facilitate overall adjustment, the positioning element 64 is connected to the controller 4 by signal, and the controller 4 is used for regulation.

[0108] The electrode and diffusion layer are placed on the second electrode portion 12, and then the positioning member 64 is activated, causing the positioning plate 63 to press firmly on the diffusion layer. This can reduce the problem of the electrode and diffusion layer slipping relative to the second electrode portion 12 and improve the stability of the electrode and diffusion layer during subsequent welding.

[0109] When it is necessary to place the electrode and diffusion layer on the second electrode portion 12, or to remove the electrode and diffusion layer from the second electrode portion 12, firstly, the positioning member 64 moves the positioning plate 63 away from the diffusion layer, and then the sliding member 62 moves the sliding stage 61 away from the diffusion layer in the X direction until the vertical projection of the positioning plate 63 on the second electrode portion 12 does not overlap with the diffusion layer and the electrode. During the pick-up and put-down operation, it is not easy to be blocked by the positioning plate 63, the operation is more convenient, and it can also reduce the problem of damage to the electrode and diffusion layer caused by improper operation.

[0110] Of course, in actual operation, the sliding stage 61 moves away from the diffusion layer along the X direction. In the final state, the vertical projection of the positioning plate 63 on the second pole 12 can be partially overlapped with the diffusion layer and the electrode. This can also reduce the obstruction of the diffusion layer and the electrode during the picking and placing operations to a certain extent.

[0111] In addition, a number of positioning teeth 65 are fixedly connected to the positioning plate 63. By matching the toothed structure of the diffusion layer with the positioning teeth 65, the positioning teeth 65 are located in the grooved structure on the diffusion layer when the diffusion layer is positioned, which can reduce the problem of deformation and damage to the diffusion layer caused by pressing the diffusion layer.

[0112] In another embodiment, two positioning components 6 can be positioned on opposite sides of the support plate 31 in the Y direction. In this case, the sliding stage 61 should slide relative to the support plate 31 in the Y direction, moving closer to or further away from the electrode and diffusion layer located on the second electrode portion 12. In other embodiments, the two positioning components 6 can be positioned on opposite sides of the support plate 31, not necessarily along the X or Y direction. In this case, the sliding stage 61 slides relative to the support plate 31 through the center of the second electrode portion 12 (i.e., the center of the electrode and diffusion layer located on the second electrode portion 12).

[0113] Furthermore, the number of positioning components 6 can be adjusted according to actual needs, and can be set to one, three, four, or any other number. Of course, in order to maintain a good positioning effect, when multiple positioning components 6 are set, the multiple positioning components 6 should be arranged evenly around the second pole 12 as much as possible. This application only takes the setting of two positioning components 6, and the two positioning components 6 are located on the two sides of the support plate 31 that are far apart from each other in the X direction, to abut and position the electrode and the diffusion layer on the two sides that are far apart from each other in the X direction as an example. However, this does not limit the scope of protection of this application.

[0114] Furthermore, when the size of the electrode and the diffusion layer is large, the two positioning components 6 are used to press and position the electrode and the diffusion layer. However, this can easily cause the edge of the electrode or the diffusion layer to lift up between the two positioning components 6, resulting in a deviation in the positioning accuracy of the electrode and the diffusion layer, which may affect the subsequent welding quality.

[0115] Therefore, refer to Figure 4 and Figure 7 The welding equipment is also equipped with multiple anti-warping components 7, which are used to press the edges of the electrode and diffusion layer to reduce the problem of the electrode and diffusion layer edges warping and improve positioning accuracy. In this embodiment, four anti-warping components 7 are used as an example. All four anti-warping components 7 are set on the support plate 31 and are evenly spaced. In other embodiments, the number of anti-warping components 7 can be adjusted adaptively.

[0116] Specifically, refer to Figure 8 and combined Figure 7 The anti-tilting component 7 includes a mounting frame 71, a mounting platform 72, an adjusting member 73, and an anti-tilting rod 74. The mounting frame 71 is fixedly connected to the support plate 31 and is located on the side of the support plate 31 away from the second pole part 12, reducing the space occupied by the support plate 31 and the upper side of the second pole part 12. The mounting platform 72 is slidably connected to the mounting frame 71 in the Z direction. The adjusting member 73 is fixedly connected to the mounting frame 71 and is used to drive the mounting platform 72 to slide relative to the mounting frame 71 and lock the position of the mounting platform 72. The anti-tilting rod 74 is disposed on the mounting platform 72. Both the support plate 31 and the second pole part 12 have through holes for the anti-tilting rod 74 to pass through. The anti-tilting rod 74 is located on the side of the second pole part 12 away from the support plate 31 and is connected to the mounting platform 72 through the through holes.

[0117] After the electrode and diffusion layer are placed on the second electrode portion 12, the adjusting member 73 drives the mounting platform 72 and the anti-tilting rod 74 to slide, causing the anti-tilting rod 74 to abut against the diffusion layer, thereby positioning the diffusion layer and reducing the problem of partial edge lifting of the electrode and diffusion layer during subsequent welding, thus improving the positioning accuracy of the electrode and diffusion layer. Furthermore, by placing the mounting bracket 71, mounting platform 72, and adjusting member 73 on the side of the support plate 31 away from the second electrode portion 12, the space occupied by the electrode and diffusion layer on the second electrode portion 12 can be reduced, and the operation of picking up and placing the electrode and diffusion layer is less likely to be obstructed.

[0118] For the sliding connection between the mounting platform 72 and the mounting bracket 71, and the adjustment component 73 driving the mounting platform 72 to slide relative to the mounting bracket 71, the mounting plate 22 and the fixed plate 21 are slidably connected, and the first power component 23 drives the mounting plate 22 to slide and lock the mounting plate 22.

[0119] In addition, the anti-tilting rod 74 is fixedly connected to an abutment post 75 at the end away from the mounting platform 72. The cross-sectional dimension of the abutment post 75 is smaller than the width of the grooved portion on the diffuser layer of the toothed structure, and the abutment post 75 is located in the grooved structure on the diffuser layer, which reduces the problem of deformation of the diffuser layer caused by pressure.

[0120] The anti-tilting assembly 7 also includes a rotating component 76 fixedly connected to the mounting platform 72, and an anti-tilting rod 74 fixedly connected to the output end of the rotating component 76, thereby realizing the rotatable connection between the anti-tilting rod 74 and the mounting platform 72, and the rotation axis of the anti-tilting rod 74 is parallel to the Z direction; for example, the rotating component 76 is a servo motor, and the anti-tilting rod 74 is fixedly connected to the output shaft of the servo motor.

[0121] The anti-tilting rod 74 is designed to rotate relative to the mounting platform 72. When placing or removing electrodes and the diffusion layer, the anti-tilting rod 74 can be adjusted to avoid obstruction and damage to the electrodes or diffusion layer. Furthermore, through holes in the support plate 31 and the second electrode portion 12 allow the anti-tilting rod 74 to pass through, enabling it to be adjusted to the side of the support plate 31 away from the second electrode portion 12. This facilitates future replacements of the second electrode portion 12 without requiring disassembly of the anti-tilting rod 74.

[0122] Additionally, it should be noted that the positioning component 6 and the anti-lifting component 7 are both designed to clamp and limit the edges of the electrode and the diffusion layer. During the welding process, the first electrode 11 moves relative to the diffusion layer for welding. To further improve the stability of the electrode and diffusion layer positions during the welding process, refer to... Figure 1 The welding equipment also includes a clamping assembly 8 for positioning the diffusion layer.

[0123] Specifically, refer to Figure 9 The clamping assembly 8 includes a clamping plate 81 that is slidably connected to the frame 1 along the Z direction and a clamping member 82 that is fixedly connected to the frame 1 for driving the clamping plate 81 to slide. At the same time, the clamping member 82 locks the position of the clamping plate 81 to position the diffusion layer. For example, the clamping plate 81 can also be slidably connected to the frame 1 by a guide rail slider connection structure. The clamping member 82 is a cylinder, and the piston rod of the cylinder is fixedly connected to the clamping plate 81 to drive the clamping plate 81 to slide along the Z direction. The clamping member 82 is also signal-connected to the controller 4, and the action of the clamping member 82 is controlled by the controller 4.

[0124] The clamping plate 81 is arranged along the X direction, and the distance between the clamping plate 81 and the first pole 11 in the Y direction is small. Here, small distance means that the two are not in contact, but not too far apart. The first pole 11 abuts against the diffusion layer and rolls along the X direction. The clamping plate 81 presses the diffusion layer. On the current welding path, the clamping plate 81 presses and positions the side of the welding path, thereby improving the accuracy of welding.

[0125] Two clamping plates 81 are provided, both of which extend along the X direction, and a gap is provided between the two clamping plates 81 for the first pole 11 to pass through. The two clamping plates 81 simultaneously clamp the diffusion layer on both sides of the welding path, which improves the clamping and positioning effect of the diffusion layer. During the welding process, the problem of diffusion layer skewing is less likely to occur, thus improving the welding quality.

[0126] In addition, refer to Figure 10 Considering that the diffusion layer itself has a toothed structure, a toothed plate 83 is fixedly connected to the side of the clamping plate 81 facing the second pole 12. The surface of the toothed plate 83 facing the second pole 12 has a toothed structure that is compatible with the diffusion layer. Under the condition of clamping the diffusion layer to position it, it is not easy to cause the diffusion layer to deform.

[0127] For example, the surface of the toothed plate 83 facing the second electrode 12 has multiple spaced protrusions, so that the side of the toothed plate 83 facing the second electrode 12 forms a toothed structure; both sides of the surface of the protrusions facing the second electrode 12 are chamfered, which can play a certain guiding role when the protrusions on the toothed plate 83 are inserted into the groove structure of the diffusion layer. In the case of a small deviation, the diffusion layer at the corresponding position of the toothed plate 83 can be adjusted accordingly to improve the welding effect.

[0128] The toothed plate 83 is detachably and fixedly connected to the clamping plate 81, and multiple sets of toothed plates 83 with different tooth shapes and sizes are provided. When the structure and size of the diffusion layer to be welded are different, the toothed plate 83 can be replaced accordingly to achieve a better clamping and positioning effect on the diffusion layer.

[0129] It should also be noted that, as a semi-automatic machine tool, this welding equipment is equipped with corresponding safety protection measures to ensure operational safety. For example, it is equipped with an emergency stop switch, which can promptly stop the operation in the event of a malfunction or processing problem, protecting the safety of the workers and reducing material loss. In the specific implementation, relevant technologies mastered in related fields can be adopted on this welding equipment to improve the safety of the operation process, which will not be elaborated upon here.
