Description

Technical Field

[0001] This utility model relates to the technical field of battery production, and in particular to a nickel sheet welding and positioning device. Background Technology

[0002] In today's society, cylindrical batteries are widely used in various fields due to their compact structure, high energy density, and good stability. For example, in portable electronic devices, they provide reliable power for laptops, smartphones, and digital cameras; in electric vehicles, they are an important component of the power systems for electric bicycles and electric cars; and they are also used in energy storage devices and power tools. In practical applications, to meet the different power demands of various devices, multiple battery cells are often connected in series or parallel to form battery packs to achieve higher voltage and larger capacity. However, the ends of individual battery cells lack a direct and effective electrical connection structure. Therefore, nickel plates need to be welded to the ends of the batteries to serve as an electrical bridge between the battery cell and external circuits or other battery cells, ensuring stable current transmission and the normal operation of the battery pack. Currently, the industry commonly uses manual positioning to weld the nickel plates to the ends of the cylindrical batteries.

[0003] However, existing nickel sheet welding methods have the following shortcomings in practical applications: manual operation makes it difficult to accurately control the positioning of each nickel sheet, resulting in inconsistent protrusion lengths of the nickel sheets on the welded battery. This inconsistency not only seriously affects the assembly accuracy and electrical performance during subsequent battery pack connection but also increases production management costs, reduces production efficiency and product quality, failing to meet the current urgent demand for high-quality, standardized battery production. Therefore, this application proposes a nickel sheet welding positioning device. Utility Model Content

The first clamping piece and the second clamping piece are slidably disposed on the base, and the two ends of the first clamping piece and the second clamping piece are respectively located in the clamping groove and the locking groove. One end of each locking spring is respectively disposed on one side surface of the first clamping piece and the second clamping piece. Each locking spring pushes against the two opposing inner sidewalls of the locking groove to bring the first clamping piece and the second clamping piece closer to each other, thereby causing the ends of the first clamping piece and the second clamping piece away from the locking groove to clamp the nickel sheet together.

[0009] Optionally, the positioning component further includes a torsion block, which is rotatably disposed within the locking groove, with its two ends abutting against the first clamping piece and the second clamping piece, respectively.

[0012] Optionally, the positioning component further includes a cover plate disposed on the base. The cover plate has an anti-cavity groove, which together with one side of the base forms a sliding cavity, in which the first clamping piece and the second clamping piece slide.

[0013] Optionally, the positioning assembly further includes a top block and a clamping spring. The base is also provided with a top groove, which communicates with the clamping groove. The top block is slidably disposed in the top groove. The two ends of the clamping spring abut against the inner bottom wall of the top groove and the top block, respectively. The clamping spring pushes the top block to extend out of the top groove so that the top block and the cover plate clamp the nickel sheet together.

[0014] Optionally, one end of the top block has a semi-circular structure.

[0015] Optionally, the positioning component further includes a pusher seat, which is slidably disposed on the support plate.

[0017] Optionally, a first locking block is provided on the push base, and a second locking block is provided on the base, and the push base drives the first locking block to abut against the second locking block.

[0039] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," 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. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0043] like Figures 1 to 5 , Figures 7 to 16 As shown, in one embodiment, a nickel sheet welding positioning device 1 includes a support plate 10 and a positioning component 20. A base 11 is rotatably disposed on the support plate 10. The base 11 has a clamping groove 110 and a locking groove 112. The positioning component 20 includes a first clamping piece 21, a second clamping piece 22 and a plurality of locking springs 23. The first clamping piece 21 and the second clamping piece 22 are slidably disposed on the base 11, and the two ends of the first clamping piece 21 and the second clamping piece 22 are respectively located in the clamping groove 110 and the locking groove 112. One end of each locking spring 23 is respectively disposed on one side surface of the first clamping piece 21 and the second clamping piece 22. Each locking spring 23 pushes against the two opposing inner sidewalls of the locking groove 112 to bring the first clamping piece 21 and the second clamping piece 22 closer to each other, so that the ends of the first clamping piece 21 and the second clamping piece 22 away from the locking groove 112 jointly clamp the nickel sheet 40.

[0044] It should be noted that, for ease of description, the base 11 is described as being placed on the support plate 10. One edge of the base 11 perpendicular to the support plate 10 is rotatably connected to one edge of the support plate 10, allowing the base 11 to rotate and flip relative to the support plate 10. Furthermore, a clamping groove 110 is formed on the top surface of the base 11, with one end extending to the side of the base 11 away from the side rotatably connected to the support plate 10. A locking groove 112 is formed on the side of the base 11 rotatably connected to the support plate 10, with one end extending to the top surface of the base 11. Furthermore, the first clip 21 is provided with a first protrusion 210 and a first insert 211 at both ends, and the second clip 22 is provided with a second protrusion 220 and a second insert 221 at both ends. The first protrusion 210 and the second protrusion 220 are both located in the clip groove 110, and the first insert 211 and the second insert 221 are both located in the locking groove 112. Thus, when the first clip 21 and the second clip 22 slide in opposite directions, the first insert 211 and the second insert 221 move closer to each other or further away from each other in the locking groove 112, and at the same time, the first protrusion 210 and the second protrusion 220 move closer to each other or further away from each other in the clip groove 110. Furthermore, one end of each locking spring 23 is respectively disposed on the side surface of the first insert 211 and the second insert 221 that are far apart from each other, and the other end of each locking spring 23 abuts against the two inner side walls of the locking groove 112 facing each other. In this way, each locking spring 23 pushes the two inserts closer to each other, thereby causing the first protrusion 210 and the second protrusion 220 to come closer to each other to clamp the nickel sheet 40 together. Furthermore, both the first protrusion 210 and the second protrusion 220 are parallel to the two inner sidewalls facing each other in the clamping groove 110. Specifically, when the operator inserts the nickel sheet 40 into the clamping groove 110 so that one end of the nickel sheet 40 abuts against the inner bottom wall of the clamping groove 110, under the pushing of each locking spring 23, the first protrusion 210 and the second protrusion 220 push against the two sides facing each other of the nickel sheet 40 respectively, so that the nickel sheet 40 and the clamping groove 110 remain parallel. In this way, while clamping the nickel sheet 40, the nickel sheet 40 can maintain a parallel state and a fixed extension length, thereby making the extension length of the nickel sheet 40 uniform after welding.

[0045] like Figures 6 to 8 , Figures 10 to 11 , Figure 16 As shown, in one embodiment, the positioning component 20 further includes a torsion block 24, which is rotatably disposed in the locking groove 112, and the two ends of the torsion block 24 abut against the first clamping piece 21 and the second clamping piece 22 respectively.

[0046] It should be noted that the torsion block 24 is rotatably mounted on the inner bottom wall of the locking groove 112, and the torsion block 24 is located between the first insertion block 211 and the second insertion block 221. In this way, when each locking spring 23 pushes the first insertion block 211 and the second insertion block 221 closer to each other, the first insertion block 211 and the second insertion block 221 can abut against the opposite ends of the torsion block 24.

[0047] like Figures 7 to 8 , Figures 10 to 11 , Figure 16 As shown, in one embodiment, the twist block 24 has an elliptical structure.

[0048] It should be noted that the torsion block 24 has an elliptical structure, giving it a major axis end and a minor axis end. Since the first insertion block 211 and the second insertion block 221 abut against the opposing ends of the torsion block 24 under the pushing force of the locking springs 23, when the torsion block 24 rotates, the sides of the first insertion block 211 and the second insertion block 221 closest to the torsion block 24 will slide and abut against it circumferentially. When the torsion block 24 is rotated so that the two ends of the major axis abut against the first insertion block 211 and the second insertion block 221 respectively, the torsion block 24 will push the first insertion block 211 and the second insertion block 221 away from each other and compress the locking springs 23 respectively. When the torsion block 24 is rotated so that the two ends of the major axis are away from the first insertion block 211 and the second insertion block 221 respectively, the locking springs 23 will push the first insertion block 211 and the second insertion block 221 closer to each other and abut against the two ends of the minor axis of the torsion block 24. Thus, when the first insert 211 and the second insert 221 approach each other, the first protrusion 210 and the second protrusion 220 move away from each other from the nickel sheet 40. When the first insert 211 and the second insert 221 approach each other under the push of each locking spring 23, the first protrusion 210 and the second protrusion 220 also approach each other to clamp the nickel sheet 40 together.

[0049] like Figures 7 to 8 , Figures 10 to 11 , Figure 16 As shown, in one embodiment, a flat portion 240 is provided at both ends of the long shaft of the twisting block 24, a first groove 2110 is provided on the first clamping piece 21, and a second groove 2210 is provided on the second clamping piece 22. Each flat portion 240 abuts against the first groove 2110 and the second groove 2210 respectively.

[0050] It should be noted that the two flat portions 240 are respectively formed at the ends of the long shaft of the twist block 24, and the two flat portions 240 are parallel to each other. Further, the first groove 2110 is formed on the side of the first insert 211 facing the twist block 24, and the second groove 2210 is formed on the side of the second insert 221 facing the twist block 24. The shapes of the first groove 2110 and the second groove 2210 are consistent with the shape of the flat portions 240. When the twist block 24 is rotated, the two flat portions 240 respectively engage with the first groove 2110 and the second groove 2210. Under the pushing force of each locking spring 23, the first insert 211 and the second insert 221 can remain in contact with both ends of the long shaft of the twist block 24. This keeps the first protrusion 210 and the second protrusion 220 away from each other to open the clamping groove 110, so that the operator can insert the nickel sheet 40 into the clamping groove 110. Furthermore, after the nickel sheet 40 is inserted into the clamping groove 110, the torsion block 24 is rotated to allow the two ends of the long shaft to slide out from the first groove 2110 and the second groove 2210 respectively, and when the two ends of the short shaft of the torsion block 24 abut against the first insert 211 and the second insert 221 respectively, under the pushing of each locking spring 23, the first protrusion 210 and the second protrusion 220 move closer to each other to clamp the nickel sheet 40 together, and the first protrusion 210 and the second protrusion 220 maintain the state of clamping the nickel sheet 40, which facilitates welding in subsequent processes, thereby improving production efficiency. Furthermore, since one end of the clamping groove 110 extends to one side of the base 11, when the nickel sheet 40 is inserted into the clamping groove 110, one end of the nickel sheet 40 can protrude from one side of the base 11, so that the nickel sheet 40 can be welded to the electrode of the cylindrical battery 50. Furthermore, after the nickel sheet 40 and the electrode of the cylindrical battery 50 are welded together, the operator can pull the cylindrical battery 50 along the direction of the groove 110 to pull the nickel sheet 40 out of the groove 110. This reduces the operator's work steps and improves the efficiency of the work after welding.

[0051] like Figures 1 to 2 , Figure 6 , Figure 15 As shown, in one embodiment, the positioning component 20 further includes a cover plate 25, which is disposed on the base 11. A clearance groove 250 is provided on the cover plate 25, and the clearance groove 250 and one side of the base 11 together form a sliding cavity. The first clamping piece 21 and the second clamping piece 22 slide in the sliding cavity.

[0052] It should be noted that the first insert 211 and the first protrusion 210 are both disposed on one side of the first clamping piece 21, and the second insert 221 and the second protrusion 220 are both disposed on one side of the second clamping piece 22. When the first insert 211 and the second insert 221 are both located in the locking groove 112, and the first protrusion 210 and the second protrusion 220 are both located in the clamping groove 110, the middle position of the first clamping piece 21 and the second clamping piece 22 protrudes relative to the base 11. Furthermore, the cover plate 25 is disposed on the base 11. For example, the cover plate 25 is disposed on the end face of the base 11 where the clamping groove 110 is opened by screws, and the clearance groove 250 is close to the end face of the base 11, so that the clearance groove 250 and the end face of the base 11 together form a sliding cavity, and the middle positions of the first clamping piece 21 and the second clamping piece 22 are both located in the sliding cavity. In this way, the first clamping piece 21 and the second clamping piece 22 can slide in the sliding cavity, so that when the first insert 211 and the second insert 221 approach each other, they can drive the first protrusion 210 and the second protrusion 220 to approach each other to clamp the nickel sheet 40 together.

[0053] like Figures 4 to 9 As shown, in one embodiment, the positioning component 20 further includes a top block 26 and a clamping spring 27. A top groove is also provided on the base 11, which is connected to the clamping groove 110. The top block 26 is slidably disposed in the top groove. The two ends of the clamping spring 27 abut against the inner bottom wall of the top groove and the top block 26, respectively. The clamping spring 27 pushes the top block 26 to extend out of the top groove so that the top block 26 and the cover plate 25 together clamp the nickel sheet 40.

[0054] It should be noted that the top groove is located on the inner bottom wall of the clamping groove 110, allowing the top groove to communicate with the clamping groove 110. Furthermore, the top block 26 slides within the top groove, while the clamping spring 27 is located within the top groove. The two ends of the clamping spring 27 abut against the inner bottom wall of the top groove and one end of the top block 26, respectively, and the clamping spring 27 will push the top block 26 to slide out from within the top groove. Since the cover plate 25 is located on the end face of the base 11 where the clamping groove 110 is formed, the clamping spring 27 pushes the top block 26 across the clamping groove 110 to abut against the cover plate 25. At this time, the top block 26 and the cover plate 25 together surround the clamping groove 110, so that the clamping groove 110 forms a cavity. Specifically, the opening of the clamping groove 110 faces the top surface of the base 11, and one side of the clamping groove 110 is connected to the side of the base 11. When the cover plate 25 is placed on the base 11, the cover plate 25 seals the opening of the clamping groove 110. At this time, the clamping groove 110 only has the opening connected to the side of the base 11. When the clamping spring 27 pushes the top block 26 across the clamping groove 110 to abut against the cover plate 25, the top block 26 seals the opening of the clamping groove 110 connected to the side of the base 11. In this way, the top block 26 and the cover plate 25 together seal the clamping groove 110 to form a cavity. Furthermore, when the nickel sheet 40 is inserted into the opening of the clamping groove 110 towards the base 11, the nickel sheet 40 pushes the top block 26 into the top groove, while simultaneously compressing the clamping spring 27, thus allowing the nickel sheet 40 to be inserted into the clamping groove 110. At this time, due to the pushing force of the clamping spring 27, the top block 26 continuously pushes one side of the nickel sheet 40 to bring the nickel sheet 40 closer to the cover plate 25, so that the cover plate 25 and the top block 26 together clamp the upper and lower sides of the nickel sheet 40. When the nickel sheet 40 is completely inserted into the clamping groove 110, the top block 26 and the cover plate 25 together clamp the upper and lower sides of the nickel sheet 40, and the first protrusion 210 and the second protrusion 220 together clamp the two opposing sides of the nickel sheet 40. In this way, the nickel sheet 40 can be firmly fixed on the base 11, preventing the nickel sheet 40 from shifting during the welding process, so as to facilitate precise welding of the nickel sheet 40 to the electrodes of the cylindrical battery 50, thereby improving the welding accuracy.

[0055] like Figures 4 to 6 , Figure 9 As shown, in one embodiment, one end of the top block 26 has an arc-shaped structure.

[0056] It should be noted that the end of the top block 26 away from the clamping spring 27 is a semi-circular structure, and the arc of the semi-circular structure faces the opening of the clamping groove 110, so that when the nickel sheet 40 is inserted into the clamping groove 110, the end of the nickel sheet 40 can abut against the semi-circular structure, thereby allowing the nickel sheet 40 to push the top block 26 into the top groove.

[0057] like Figures 1 to 3 , Figure 14As shown, in one embodiment, the positioning component 20 further includes a pusher 28, which is slidably disposed on the support plate 10. A first semi-circular groove 280 is provided on the pusher 28, and a second semi-circular groove 113 is provided on the base 11. The pusher 28 drives the first semi-circular groove 280 to slide close to the second semi-circular groove 113 to jointly clamp the cylindrical battery 50.

[0058] It should be noted that a second semicircular groove 113 is provided on the base 11, and the second semicircular groove 113 is provided along the vertical direction of the base 11. One end of the second semicircular groove 113 is connected to the clamping groove 110, and the extension direction of the clamping groove 110 is perpendicular to the axial direction of the second semicircular groove 113. Thus, when one end of the nickel sheet 40 is inserted into the clamping groove 110, the other end of the nickel sheet 40 will extend into the second semicircular groove 113 and be located at the end of the second semicircular groove 113 near the base 11. Furthermore, a first semicircular groove 280 is provided on the push base 28. The diameter of the first semicircular groove 280 is adapted to the diameter of the cylindrical battery 50, and the diameter of the first semicircular groove 280 is the same as that of the second semicircular groove 113. When the pusher 28 moves the first semicircular groove 280 closer to the second semicircular groove 113, the first semicircular groove 280 and the second semicircular groove 113 can clamp the cylindrical battery 50 together, so that the cylindrical battery 50 is fixed on the base 11 and the electrode of the cylindrical battery 50 is located below the nickel sheet 40 extending from the clamping groove 110, so that the nickel sheet 40 and the electrode of the cylindrical battery 50 can be welded.

[0059] like Figures 1 to 4 , Figure 7 , Figure 10 , Figure 14 As shown, in one embodiment, a first locking block 281 is provided on the push base 28, and a second locking block 114 is provided on the base 11. The push base 28 drives the first locking block 281 to abut against the second locking block 114.

[0060] It should be noted that a first locking block 281 is laterally arranged on one side of the push base 28, and the end of the first locking block 281 facing the base 11 extends relative to the push base 28. Furthermore, the first locking block 281 and the second locking block 114 are both arranged parallel to each other, and both are parallel to the sliding direction of the push base 28. The first locking block 281 and the second locking block 114 are not on a straight line, but are staggered. Specifically, when the push base 28 slides close to the base 11 so that the first semicircular groove 280 and the second semicircular groove 113 together clamp the cylindrical battery 50, the portion of the first locking block 281 extending relative to the push base 28 and the portion of the second locking block 114 extending relative to the base 11 will approach each other and stand side-by-side. For example, the first locking block 281 is located on the side of the second locking block 114 away from the base 11 and rotatably connected to the support plate 10. Since the first locking block 281 and the second locking block 114 are both arranged in parallel, when the pusher 28 drives the first locking block 281 to be parallel to and tightly pressed against the second locking block 114, the base 11 cannot rotate relative to the support plate 10, thus preventing the base 11 from causing the nickel sheet 40 / cylindrical battery 50 to flip, thereby fixing the nickel sheet 40 and the cylindrical battery 50 on the base 11. In this way, when the pusher 28 slides closer to the base 11 to clamp the cylindrical battery 50, it can lock the base 11, preventing it from flipping. Furthermore, the edges where the first locking block 281 and the second locking block 114 approach each other are beveled, allowing the first locking block 281 to slide above the second locking block 114 when they approach, thereby locking the base 11 with the pusher 28 and preventing it from flipping.

[0061] It should be noted that when the operator needs to insert the nickel sheet 40 into the clamping groove 110, the base 11 can be flipped so that the opening of the clamping groove 110 on the base 11 faces upward, making it easier for the operator to quickly insert the nickel sheet 40 from top to bottom, thereby improving work efficiency. Furthermore, a bracket 282 is provided on the end of the push base 28 near the support plate 10. The bracket 282 has an annular groove 2821 that can accommodate the cylindrical battery 50, and the annular groove 2821 is coaxially aligned with the first semi-circular groove 280. In this way, the operator can insert the cylindrical battery 50 into the annular groove 2821, and make the cylindrical battery 50 coaxially embedded in the first semi-circular groove 280. Furthermore, when the operator flips the base 11 with the nickel sheet 40 inserted so that its top surface faces upwards, the pusher 28 moves the cylindrical battery 50 located in the annular groove 2821 closer to the second semi-circular groove 113. This causes the first semi-circular groove 280 and the second semi-circular groove 113 to clamp the cylindrical battery 50 together. Simultaneously, the electrodes of the cylindrical battery 50 are positioned below the end of the nickel sheet 40 that extends from the clamping groove 110. At the same time, the first locking block 281 is positioned side-by-side against the second locking block 114 above to fix the base 11 and prevent it from flipping. This ensures that the nickel sheet 40 and the electrodes of the cylindrical battery 50 are precisely fixed together, thereby improving welding accuracy.

[0062] like Figures 1 to 2 , Figure 4 , Figure 7 , Figure 10 , Figures 12 to 14As shown, in one embodiment, multiple clamping grooves 110, top grooves, and second semicircular grooves 113 are provided, with each clamping groove 110, top groove, and second semicircular groove 113 being equidistantly distributed and corresponding one-to-one. Further, multiple first protrusions 210 are provided, with each first protrusion 210 being equidistantly distributed on the same side of the first clamping piece 21 and corresponding one-to-one with each clamping groove 110. Further, multiple second protrusions 220 are provided, with each second protrusion 220 being equidistantly distributed on the same side of the second clamping piece 22 and corresponding one-to-one with each clamping groove 110. Furthermore, multiple top blocks 26 and clamping springs 27 are provided. Each top block 26 slides in a corresponding top groove, and each clamping spring 27 is located in a corresponding top groove, and each clamping spring 27 abuts against a corresponding top block 26. Furthermore, multiple first semicircular grooves 280 are provided, equidistantly distributed on the side of the pusher 28 facing the base 11, with all first semicircular grooves 280 having the same opening direction. Each first semicircular groove 280 corresponds to a corresponding second semicircular groove 113. When the pusher 28 moves each first semicircular groove 280 closer to each second semicircular groove 113, one first semicircular groove 280 and one second semicircular groove 113 can clamp a cylindrical battery 50. Furthermore, multiple annular grooves 2821 are provided, each annular groove 2821 corresponding to a corresponding first semicircular groove 280. Thus, each clamping groove 110, each top groove, each first protrusion 210, each second protrusion 220, each first semicircular groove 280, each second semicircular groove 113, each top block 26, each clamping spring 27, and each annular groove 2821 corresponds one-to-one, allowing the operator to simultaneously place multiple cylindrical batteries 50 into the annular groove 2821 and simultaneously insert multiple nickel sheets 40 into the clamping groove 110. This enables the operator to simultaneously clamp and position multiple nickel sheets 40 and cylindrical batteries 50, thereby improving welding efficiency.

[0063] like Figures 1 to 2 , Figure 4 , Figures 6 to 7 , Figure 10 As shown, in one embodiment, two positioning components 20 are provided, with the two positioning components 20 located on the top and bottom surfaces of the base 11, respectively.

[0064] It should be noted that, for ease of description, the positioning component 20 located on the top surface of the base 11 is defined as the positive electrode positioning component, the positioning component 20 located on the bottom surface of the base 11 is defined as the negative electrode positioning component, the end of the cylindrical battery 50 with the nickel sheet 40 welded on is defined as the positive electrode, and the end of the cylindrical battery 50 without the nickel sheet 40 welded on is defined as the negative electrode. Thus, after the operator flips the base 11, multiple nickel sheets 40 are inserted into the clamping grooves 110 at one end of the top surface of the base 11. The base 11 is then flipped parallel to the support plate 10, and the pusher 28 is pushed to bring multiple cylindrical batteries 50 closer to the base 11, so that the positive electrodes of each cylindrical battery 50 are correspondingly located below each nickel sheet 40 for welding. After the positive electrodes of the cylindrical batteries 50 are welded, the pusher 28 moves each cylindrical battery 50 away from the base 11. The operator flips each cylindrical battery 50 so that the negative terminal of the cylindrical battery 50 faces upward and the positive terminal faces downward, so that the nickel sheet 40 is located in the hollow position. At this time, the operator can flip the base 11 again to insert another batch of nickel sheets 40 into the clamping groove 110 and flip it parallel to the support plate 10. The pusher 28 once again moves each cylindrical battery 50 closer to the base 11, so that each nickel sheet 40 welded to the positive terminal of each cylindrical battery 50 is inserted into the clamping groove 110 on the negative terminal positioning assembly one by one. Since each nickel sheet 40 has been welded and fixed to the positive terminal of the cylindrical battery 50, when the first protrusion 210 and the second protrusion 220 on the positive terminal positioning assembly clamp the nickel sheet 40 together, the nickel sheet 40 can drive the cylindrical battery 50 to rotate. After the nickel sheet 40 is welded to the negative electrode of the cylindrical battery 50, the nickel sheets 40 at both ends of the cylindrical battery 50 will face the same direction and extend to the same length. This ensures the assembly accuracy and electrical performance during subsequent battery pack connection, thereby meeting the current requirements for high-quality and standardized battery production.

[0065] like Figures 1 to 2 As shown, in one embodiment, the nickel sheet welding positioning device 1 further includes a base plate 29, two slide rails 30, and several sliders 31. The two slide rails 30 are arranged parallel to each other on the base plate 29, and each slider 31 is disposed on the bottom surface of the support plate 10 away from the base 11. Each slider 31 is slidably connected to the two slide rails 30, allowing the support plate 10 to slide relative to the base plate 29. Thus, when the operator inserts multiple nickel sheets 40 into the base 11 and embeds multiple cylindrical batteries 50 into the pusher 28, with each cylindrical battery 50 positioned below each nickel sheet 40, the support plate 10 is pushed to move each nickel sheet 40 and each cylindrical battery 50 to the bottom of the welding equipment for welding. After welding is completed, the support plate 10 is pulled to move the cylindrical batteries 50 with welded nickel sheets 40 away from the welding equipment, thereby improving the convenience of the operator's welding work.

[0066] like Figures 1 to 2As shown, in one embodiment, the positioning component 20 further includes a screw 32 and a handwheel 33. The screw 32 is disposed on one side of the support plate 10, and one end of the screw 32 is rotatably connected to the end of the push seat 28 away from the base 11. The other end of the screw 32 is coaxially connected to the handwheel 33. Thus, the operator can rotate the handwheel 33 to drive the push seat 28 to slide closer to or away from the base 11.
