Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to an assembly apparatus for a nickel foam plate and a battery electrode plate. Background Technology

[0002] As an energy storage technology with broad application prospects, flow batteries are playing an increasingly important role in the field of energy storage. Among the many key components of flow batteries, the nickel foam plate and electrode plate play a crucial role, and their assembly precision has a profound impact on the overall performance of the flow battery.

[0003] In related technologies, nickel foam plates and electrode plates are typically assembled manually. Because nickel foam is relatively soft, it is difficult to control the assembly precision during manual assembly. Insufficient assembly precision leads to poor contact between the nickel foam plate and the electrode plate, thereby reducing the overall performance of the flow battery. Utility Model Content

[0004] Therefore, it is necessary to provide an assembly device for nickel foam plates and battery plates to address the above problems. This device can improve the assembly accuracy of nickel foam plates and electrode plates, which is beneficial to improving the overall performance of the battery.

[0008] The conveying mechanism is capable of extracting the nickel foam board from the feeding mechanism and conveying the nickel foam board sequentially from the feeding mechanism to the positioning station and the assembly station along the first direction;

[0009] A positioning mechanism is provided in the positioning station. The positioning mechanism includes a first limiting member, a second limiting member, a first positioning member, and a second positioning member. The first limiting member and the first positioning member are spaced apart and relatively distributed along a first direction. At least a portion of the first positioning member is movable along the first direction to push the nickel foam board against one side of the first limiting member. The second limiting member and the second positioning member are spaced apart and relatively distributed along a second direction. At least a portion of the second positioning member is movable along a second direction to push the nickel foam board against one side of the second limiting member. The second direction forms an angle with the first direction.

[0010] The clamping mechanism is capable of clamping the nickel foam board and the electrode plate in the assembly station.

[0011] In one embodiment, the conveying mechanism includes a moving assembly and an extraction component connected to the moving assembly. The moving assembly is disposed on the frame and is reciprocating along the first direction. The extraction component is liftable and can hold or release the nickel foam board.

[0012] In one embodiment, the extraction assembly includes a first lifting component and a suction cup, the first lifting component being connected to the moving assembly, the suction cup being disposed on the first lifting component, and the suction cup being used to adsorb the nickel foam board.

[0013] In one embodiment, the conveying mechanism further includes a first fixing member, through which the first lifting component is connected to the moving group.

[0014] In one embodiment, the clamping mechanism includes a second lifting component and a clamping member connected to the second lifting component. The second lifting component is connected to the first lifting component, and the clamping member is used to contact the nickel foam board. The clamping member is offset from the suction cup.

[0015] In one embodiment, the clamping mechanism further includes a second fixing member, and the second lifting component is connected to the first lifting component through the second fixing member.

[0016] In one embodiment, the first positioning member includes a first fixing part and a first pushing part connected to the first fixing part. The first fixing part is fixed relative to the frame, and the first pushing part is movable relative to the first fixing part along the first direction. The first pushing part is used to push the nickel foam board to move.

[0017] And / or, the second positioning member includes a second fixing part and a second pushing part connected to the second fixing part, the second fixing part being fixed relative to the frame, the second pushing part being movable relative to the second fixing part along the second direction, and the second pushing part being used to push the nickel foam board to move.

[0018] In one embodiment, when the first positioning member includes a first pushing part, the first pushing part includes a first pushing body and a first pushing plate. The size of the first pushing plate in the second direction is larger than the size of the first pushing body in the second direction. The first pushing plate is connected to the first fixing part through the first pushing body. The first pushing plate is used to contact the nickel foam board.

[0019] When the second positioning member includes a second pushing part, the second pushing part includes a second pushing body and a second pushing plate. The size of the second pushing plate in the first direction is larger than the size of the second pushing body in the first direction.

[0023] The aforementioned assembly device for nickel foam boards and battery plates utilizes a feeding mechanism, a conveying mechanism, a positioning mechanism, and a pressing mechanism. The nickel foam board to be assembled is first transferred to a positioning station. After auxiliary positioning using the first limiting component, first positioning component, second limiting component, and second positioning component in the positioning mechanism, the positioned nickel foam board is then transferred to the assembly station and pressed against the electrode plate. Compared to traditional manual assembly, the placement accuracy of the nickel foam board and electrode plate is improved from ±2mm to ±0.5mm. This allows for precise control of the assembly accuracy, ensuring product consistency and preventing poor contact between the nickel foam board and electrode plate, which could reduce the overall battery performance. Furthermore, it enables automatic positioning of the nickel foam board and automatic assembly of the nickel foam board and electrode plate, improving assembly efficiency and reducing assembly costs.

[0033] 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.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] 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.

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.

[0037] See Figure 1 , Figure 4 and Figure 5 , Figure 1 A perspective view of an assembly device for nickel foam board and battery electrode plate in some embodiments of this application is shown. Figure 4 This is a perspective view of the assembly apparatus for nickel foam plate and battery electrode plate in some embodiments of this application from another angle; Figure 5A top view of an assembly apparatus for a nickel foam board and a battery electrode plate according to some embodiments of this application is shown. An embodiment of this application provides an assembly apparatus (hereinafter referred to as the assembly apparatus) for a nickel foam board 400 and a battery electrode plate, comprising a frame 1, a feeding mechanism 2, a conveying mechanism 3, a positioning mechanism 4, and a pressing mechanism 5. The frame 1 is provided with a feeding station 100, a positioning station 200, and an assembly station 300 sequentially distributed along a first direction. The feeding mechanism 2 is disposed in the feeding station 100 and is used to store the nickel foam board 400 to be assembled. The conveying mechanism 3 can extract the nickel foam board 400 from the feeding mechanism 2 and can sequentially convey the nickel foam board 400 from the feeding mechanism 2 to the positioning station 200 and the assembly station 300 along the first direction. The positioning mechanism 4 is disposed in the positioning station 200 and, in conjunction with… Figure 3 The positioning mechanism 4 includes a first limiting member 43, a second limiting member 44, a first positioning member 41, and a second positioning member 42. The first limiting member 43 and the first positioning member 41 are spaced apart and relatively distributed along a first direction. At least a portion of the first positioning member 41 is movable along the first direction to push the nickel foam board 400 against one side of the first limiting member 43. The second limiting member 44 and the second positioning member 42 are spaced apart and relatively distributed along a second direction. At least a portion of the second positioning member 42 is movable along the second direction to push the nickel foam board 400 against one side of the second limiting member 44. The second direction is set at an angle to the first direction. The pressing mechanism 5 can press the nickel foam board 400 and the electrode plate together in the assembly station 300. In this embodiment, the first direction is perpendicular to the second direction, and the first direction is the length direction of the frame 1, i.e., the direction indicated by the X arrow in the figure, and the second direction is the width direction of the frame 1, i.e., the direction indicated by the Y arrow in the figure.

[0038] The feeding mechanism 2 contains nickel foam boards 400 to be assembled. After the conveying mechanism 3 extracts the nickel foam boards 400 from the feeding mechanism 2, it transfers the nickel foam boards 400 to the positioning station 200 along the first direction, so that the nickel foam boards 400 are placed between the first positioning member 41 and the first limiting member 43 and between the second positioning member 42 and the second limiting member 44. In this way, by moving the first positioning member 41 closer to the first limiting member 43 along the first direction, the nickel foam boards 400 can be driven to press against one side of the first limiting member 43. Similarly, by moving the second positioning member 42 closer to the second limiting member 44 along the second direction, the nickel foam boards 400 can be driven to press against one side of the second limiting member 44. With the assistance of the first positioning member 41, the first limiting member 43, the second positioning member 42, and the second limiting member 44, the nickel foam boards 400 are positioned. After the nickel foam board 400 is positioned correctly, the conveying mechanism 3 picks up the nickel foam board 400 again and moves along the first direction to place the nickel foam board 400 on the upper side of the electrode plate in the assembly station 300. Then, the clamping mechanism 5 is used to clamp the nickel foam board 400 and the electrode plate to complete the assembly of the nickel foam board 400 and the electrode plate.

[0039] This assembly device, through the cooperation of the feeding mechanism 2, conveying mechanism 3, positioning mechanism 4, and pressing mechanism 5, first transfers the nickel foam board 400 to be assembled to the positioning station 200. After auxiliary positioning using the first limiting member 43, the first positioning member 41, the second limiting member 44, and the second positioning member 42 in the positioning mechanism 4, the positioned nickel foam board 400 is then transferred to the assembly station 300 and pressed against the electrode plate. Compared with the traditional manual assembly method, the placement accuracy of the nickel foam board 400 and the electrode plate is improved from ±2mm to ±0.5mm. This allows for precise control of the assembly accuracy of the nickel foam board 400 and the electrode plate, ensuring product consistency and preventing poor contact between the nickel foam board 400 and the electrode plate, which would reduce the overall performance of the battery. In addition, it can realize automatic positioning of the nickel foam board 400 and automatic assembly of the nickel foam board 400 and the electrode plate. Automated assembly improves assembly efficiency and helps save assembly costs.

[0040] In actual implementation, before the nickel foam board 400 enters the assembly station 300, the carrier 6 moves the electrode plate to be assembled to the set position in the assembly station 300. In this way, the precise assembly of the nickel foam board 400 and the electrode plate can be guaranteed.

[0041] In some embodiments, see Figure 1 and Figure 3 The conveying mechanism 3 includes a moving assembly 31 and an extraction component connected to the moving assembly 31. The moving assembly 31 is mounted on the frame 1 and can reciprocate along a first direction. The extraction component can move up and down in the vertical direction (in the direction indicated by arrow Z in the figure) and can hold or release the nickel foam board 400. During the reciprocating movement of the moving assembly 31 along the first direction, it drives the extraction component to move in the first direction, thereby realizing the transfer of the nickel foam board 400 to be assembled.

[0042] Furthermore, the extraction component includes a first lifting component and a suction cup (not shown in the figure). The first lifting component is connected to the moving assembly 31, and the suction cup is disposed on the first lifting component. The suction cup is used to adsorb the nickel foam board 400. The lifting of the first lifting component drives the suction cup to lift, so that the suction cup can adsorb the nickel foam board 400.

[0043] In one example, the first lifting component is a lifting cylinder, such as a pneumatic cylinder or a hydraulic cylinder. Of course, in other examples, the first lifting component can be other components, such as a lead screw mechanism, etc., and no specific limitation is made on the first lifting component here.

[0044] Combination Figure 1The loading mechanism 2 includes a tooling carriage 21 on which the nickel foam boards 400 to be assembled are stored. In actual implementation, they are automatically transported to the frame 1 and fixed by an AGV (Automated Guided Vehicle).

[0045] The feeding mechanism 2 also includes a lifting component (not shown in the figure), which is used to lift the nickel foam board 400 inside the tooling carriage 21. After the extraction component descends to a set height to adsorb the topmost nickel foam board 400 inside the tooling carriage 21, the lifting component lifts the entire nickel foam board 400 inside the tooling carriage 21 by the thickness of the nickel foam board 400. The extraction component then resets in the height direction and transfers the nickel foam board 400 sequentially to the positioning station 200 and the assembly station. After the nickel foam board 400 is assembled with the electrode plate, the extraction component returns to the top of the tooling carriage 21 along the first direction. Then, the extraction component descends to a set height again to extract the next batch of assembled nickel foam boards 400. In this way, it can be ensured that the descent height of the extraction component when extracting the nickel foam board 400 is equal each time, which is beneficial for controlling the adsorption of the nickel foam board 400 by the extraction component.

[0046] Combination Figure 5 The conveying mechanism 3 also includes a first fixing member 32. The first lifting component is connected to the moving group 31 through the first fixing member 32. Under the action of the first fixing member 32, it is easy to realize the connection between the first lifting component and the moving group 31.

[0047] In one example, the moving group 31 is a servo module. Of course, in other examples, the moving group 31 can also be other structures, such as a conveyor belt module, etc. There is no specific limitation on the moving group 31 here; any structure that can move back and forth along the first direction is acceptable.

[0048] Combination Figure 1 and Figure 2The clamping mechanism 5 includes a second lifting component (not shown in the figure due to obstruction by the protective cover) and a clamping member 51 connected to the second lifting component. The second lifting component is connected to the first lifting component, and the clamping member 51 is used to contact the nickel foam board 400. The clamping member 51 is offset from the suction cup. It is understood that the first lifting component includes a first mounting part and a lifting part connected to the first mounting part. The lifting part can rise and fall relative to the first mounting part, and the first mounting part is connected to the first fixing member 32. When the first lifting component performs a lifting action, the position of the first mounting part remains fixed, and the lifting part rises and falls relative to the first mounting part. The second lifting component is connected to the first mounting part of the first lifting component. On the one hand, this prevents the second lifting component from moving when the first lifting component performs a lifting action, protecting the relative independence of the first and second lifting components. On the other hand, by connecting the second lifting member to the first mounting part of the first lifting component, when the moving assembly 31 moves the first lifting component along the first direction, it also moves the second lifting component. The second lifting component includes a second mounting portion and a lifting portion connected to the second mounting portion. The lifting portion can move up and down relative to the second mounting portion, thereby driving the clamping member 51 to move up and down. In this way, the clamping member 51 can clamp the nickel foam plate 400 and the electrode plate. In this example, the clamping member 51 is provided with a clearance hole for avoiding the suction cup. The size of the clearance hole is larger than or equal to that of the suction cup. The suction cup is avoided by the clearance hole. Since the size of the clearance hole is larger than or equal to that of the suction cup, the suction cup can move up and down relative to the clamping member 51, avoiding positional interference between the suction cup and the clamping member 51.

[0049] In actual implementation, before the clamping member 51 clamps the nickel foam board 400, the suction cup extends through the clamping member 51 to the side of the clamping member 51 facing the nickel foam board 400. After the suction cup places the nickel foam board 400 on the upper side of the electrode plate on the carrier 6, the second lifting component drives the clamping member 51 to descend, so that the clamping member 51 is located below the suction cup and clamps the nickel foam board 400. Because the nickel foam board 400 is made of relatively soft material, the nickel foam board 400 is prone to deformation near the suction cup during the process of being attracted and transferred by the suction cup. At this time, the clamping member 51 located on the side of the suction cup away from the nickel foam board 400 can limit the nickel foam board 400 and reduce the deformation of the nickel foam board 400.

[0050] To facilitate the connection between the second lifting component and the first lifting component, in one example, the clamping mechanism 5 also includes a second fixing member (not shown in the figure due to the obstruction of the protective cover 7). The second lifting component is connected to the first lifting component via the second fixing member. The second fixing member includes a first fixing section and a second fixing section connected to the second fixing section, with the first fixing section and the second fixing section arranged at an angle. In this example, the first fixing section and the second fixing section are arranged at a 90° angle, resulting in an overall L-shaped structure for the second fixing member. The first fixing section is connected to the first mounting part of the first lifting component, and the second fixing section is connected to the second mounting part of the second lifting component. Of course, in other examples, the angle between the first fixing section and the second fixing section can be flexibly set as needed, and there is no limitation on the angle between the first fixing section and the second fixing section here.

[0051] In one example, the assembly device also includes a protective cover 7, which covers at least a portion of the first lifting component, the second lifting component, and the second fixing component, thereby reducing the wind direction of external dust contamination of the first and second lifting components.

[0052] In some embodiments, see Figure 1 and Figure 3 The first positioning member 41 includes a first fixing part 411 and a first pushing part 412 connected to the first fixing part 411. The first fixing part 411 is fixed relative to the frame 1, and the first pushing part 412 is movable relative to the first fixing part 411 along a first direction. The first pushing part 412 is used to push the nickel foam board 400 to move. By moving the first pushing part 412 along the first direction relative to the first fixing part 411, the first pushing part 412 can push the nickel foam board 400 toward the first limiting member 43, so that the nickel foam board 400 is pressed against one side of the first limiting member 43, thereby achieving positioning of the nickel foam board 400 in the first direction.

[0053] When the first positioning member 41 includes a first pushing part 412, the first pushing part 412 includes a first pushing body 4121 and a first pushing plate 4122. The second pushing plate 4222 has a larger dimension in the first direction than the second pushing body 4221 in the first direction. The first pushing plate 4122 is connected to the first fixing part 411 through the first pushing body 4121. The first pushing plate 4122 is used to contact the nickel foam board 400. Setting the second pushing plate 4222 to have a larger dimension in the first direction than the second pushing body 4221 in the first direction can increase the contact area between the first pushing plate 4122 and the nickel foam board 400, which is beneficial for pushing the nickel foam board 400 to move smoothly.

[0054] The second positioning member 42 includes a second fixing part 421 and a second pushing part 422 connected to the second fixing part 421. The second fixing part 421 is fixed relative to the frame 1, and the second pushing part 422 is movable relative to the second fixing part 421 along a second direction. The second pushing part 422 is used to push the nickel foam board 400 to move. By moving the second pushing part 422 along the second direction relative to the second fixing part 421, the nickel foam board 400 can be pushed towards the second limiting member 44 by the second pushing part 422, so that the nickel foam board 400 is pressed against one side of the second limiting member 44, thereby achieving the positioning of the nickel foam board 400 in the second direction.

[0055] When the second positioning member 42 includes a second pushing part 422, the second pushing part 422 includes a second pushing body 4221 and a second pushing plate 4222. The second pushing plate 4222 is larger in the first direction than the second pushing body 4221. The second pushing plate 4222 is connected to the second fixing part 421 through the second pushing body 4221. The second pushing plate 4222 is used to contact the nickel foam board 400. Setting the second pushing plate 4222 to be larger in the first direction than the second pushing body 4221 increases the contact area between the first pushing plate 4122 and the nickel foam board 400, which is beneficial for pushing the nickel foam board 400 to move smoothly.

[0056] It should be noted that in other examples, the first positioning member 41 can be moved as a whole along the first direction, or the second positioning member 42 can be moved as a whole along the second direction. There are no specific restrictions on the structure of the first positioning member 41 and the second positioning member 42.

[0057] In one example, the first limiting member 43 includes at least two first limiting blocks 431, which are spaced apart along a second direction. The at least two spaced first limiting blocks 431 constitute the first limiting member 43, which helps to save the manufacturing materials of the first limiting member 43.

[0058] In other examples, the first limiting member 43 can also be set as an integral structure.

[0059] In one example, the second limiting member 44 includes at least two second limiting blocks 441, which are spaced apart along a first direction. The at least two spaced second limiting blocks 441 constitute the second limiting member 44, which helps to save the manufacturing materials of the second limiting member 44.

[0060] In other examples, the second limiting member 44 can also be set as an integral structure.

[0061] In some embodiments, see Figure 3The positioning mechanism 4 also includes a mounting plate 45, which is fixed to the frame 1. The first limiting member 43, the second limiting member 44, the first positioning member 41, and the second positioning member 42 are all disposed on the mounting plate 45, thus integrating these components onto the same mounting plate 45. In practice, the first limiting member 43, the second limiting member 44, the first positioning member 41, and the second positioning member 42 can be mounted onto the mounting plate 45 to form a single assembly, which is then installed onto the frame 1, facilitating the assembly of the assembly device.

[0062] Of course, in other examples, at least one of the first limiting member 43, the second limiting member 44, the first positioning member 41, and the second positioning member 42 can be directly mounted on the frame 1.

[0063] To facilitate the handling and assembly of the assembly device, the assembly device also includes casters 12, which are located at the bottom of the frame.

[0064] Furthermore, combined Figure 1 The frame 1 includes a frame body 11 and support legs 13. The frame body 11 is provided with a loading station 100, a positioning station 200 and an assembly station 300. The support legs 13 are used to support the frame body 11 on the ground.

[0065] When the assembly device includes casters 12, the casters 12 are connected to the frame body 11, and the length of the support legs 13 is adjustable. By adjusting the length of the support legs 13, the height position of the casters 12 can be adjusted, thereby enabling the casters 12 to contact or separate from the ground. When it is necessary to move the frame 1, the support legs 13 can be shortened, the casters 12 can be lowered, so that the casters 12 contact the ground and the support legs 13 separate from the ground, thus facilitating the movement of the frame 1; when it is not necessary to move the frame 1, the length of the support legs 13 can be lengthened, so that the support legs 13 contact the ground and the casters 12 separate from the ground, thus allowing the frame 1 to be placed stably on the ground.

[0066] In actual implementation, after the assembly device presses the nickel foam plate 400 and the electrode plate, it automatically exits the assembly station. The carrier 6 transfer component transfers the carrier 6 to the outside of the assembly station to prepare for the next round of assembly.

[0067] 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.
