Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle battery technology, and more specifically, it relates to an electroplating fixture for a new energy vehicle battery busbar. Background Technology

[0002] Battery modules are one of the main power sources used in new energy vehicles, storing energy and providing power. The internal wiring of this battery module is commonly referred to as a "bus." A bus typically consists of a conductor plate and connectors. The conductor plate has many shorting strips for connecting the positive and negative terminals of the battery, and the connectors connect it to other components of the battery module. The bus is characterized by the high conductivity, high strength, and high stability of the conductor plate and connector materials. Because the electrical output of a battery module is substantial, the stability and reliability of the conductive circuitry must be ensured. Electroplating is a process that uses electrolysis to deposit a thin layer of another metal or alloy onto the surface of certain metals. It utilizes electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics.

[0003] A search revealed that Chinese utility model patent application number CN202421064169.9 discloses a partial electroplating device for a busbar of a new energy battery, including an electroplating tank; it also includes: a lifting rod, which is set on both sides of the upper end of the electroplating tank, and the lower half of the lifting rod extends into the interior of the electroplating tank. The lower half of the left lifting rod is integrally formed with an external thread, and the lower half of the lifting rod is provided with a first transmission gear. The inner hole of the first transmission gear is provided with an internal thread, and the first transmission gear is threadedly connected to the external thread.

[0004] This device uses a lifting rod to move up and down outside the electroplating tank. After the fixed frame and battery busbar are placed on the crossbar, the lifting rod can be driven to lower the fixed frame and battery busbar into the electroplating tank. This facilitates the lowering of the battery busbar and its subsequent lifting after electroplating. However, it can only control the lifting of one fixed frame, making it inconvenient to fix multiple fixed frames. During the electroplating process, the battery busbar on the fixed frame can only be replaced after electroplating is completed. This results in poor continuity of battery busbar electroplating and low electroplating efficiency. In addition, it is not convenient to adjust the height between the fixed frame and the crossbar, making it difficult to adjust the height of the fixed frame and battery busbar according to the amount of electroplating solution inside the electroplating tank. It also makes it difficult to immerse battery busbars of different heights in the electroplating solution. Utility Model Content

During the electroplating process of the battery busbars on some fixed frames, it is easy to disassemble and assemble the corresponding fixed frame and replace the battery busbars on that fixed frame, ensuring the continuity of the battery busbar electroplating and improving the efficiency of the electroplating process.

[0007] The present invention is further configured such that a convex groove is provided at the bottom end of the crossbar, a convex plate is inserted into the convex groove, the bottom end of the convex plate is fixedly connected to the two lifting components, and after the convex plate is inserted into the convex groove, the front end face of the convex plate is flush with the front end face of the crossbar, which facilitates the assembly and disassembly of the fixing frame.

[0008] The present invention is further configured such that the lifting assembly includes two vertical columns, each with an adjustment groove at its bottom end, and a lifting rod slidably disposed inside each adjustment groove. A first screw that cooperates with the lifting rod is threaded to the side end of the vertical column, which facilitates the adjustment of the height of the fixed frame.

[0009] The present invention is further configured such that the positioning component includes an L-shaped plate, the L-shaped plate is fixedly connected to the top end of the crossbar, a square column is slidably arranged on the L-shaped plate, a positioning seat is fixedly connected to the bottom end of the square column, the side end of the positioning seat contacts the side end of the crossbar, a compression spring is arranged between the positioning seat and the L-shaped plate, the compression spring is sleeved on the outside of the square column, and a top plate is fixedly connected to one end of the square column extending above the L-shaped plate, thereby positioning the convex plate inside the convex groove and preventing the convex plate from sliding out of the convex groove during the electroplating process of the battery busbar.

[0010] The present invention is further configured such that the top plate is fixedly connected to the square column by a second screw, which facilitates the disassembly of the top plate and the replacement of the compression spring.

[0011] The present invention is further provided in that the side end of the fixing member is provided with an L-shaped groove, and the fixing member is provided with a through groove communicating with the L-shaped groove for suspending the copper wire, so as to suspend the copper wire on the battery busbar on the fixing member.

[0012] The present invention is further configured such that a reinforcing plate is fixedly connected to the top of the crossbar, and the side end of the reinforcing plate is fixedly connected to the side end of the lifting column, thereby improving the stability of the connection between the crossbar and the lifting column.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides an electroplating fixture for busbars of new energy vehicle batteries, which has the following beneficial effects: 1. By setting multiple crossbars, it is easy to control multiple fixed frames individually, and to electroplate the battery busbars on multiple fixed frames. During the electroplating process of the battery busbars on some fixed frames, it is easy to remove the fixed frame with the electroplated battery busbars and replace the battery busbars on the fixed frame. This ensures the continuity of battery busbar electroplating and improves the efficiency of battery busbar electroplating.

[0015] 2. The convex plate is inserted into the convex groove and connected to the crossbar, which facilitates the assembly and disassembly of the fixed frame. The lifting rod slides inside the adjustment groove, which facilitates the adjustment of the height between the fixed frame and the crossbar, and the distance between the battery busbar suspended on the fixed frame and the crossbar. When the crossbar is at its lowest point, the height of the battery busbar is adjusted. This allows for appropriate adjustment of the height of the fixed frame and the battery busbar according to the amount of electroplating solution in the electroplating tank, and also ensures that battery busbars of different heights are completely immersed in the electroplating solution.

Then, the convex plate is inserted into the convex groove. When the convex plate is fully inserted into the convex groove, the front end face of the convex plate is flush with the front end face of the crossbar. At this time, the positioning seat is pushed downward by the compression spring, so that the positioning seat blocks one side of the convex groove, thus preventing the convex plate from sliding out of the convex groove during the electroplating process of the battery busbar.

[0022] Please see Figures 1-6A new energy vehicle battery busbar electroplating fixture includes an electroplating tank 1. Multiple partitions 2 are fixedly connected inside the electroplating tank 1, dividing the tank into multiple electroplating tanks 3. A drain pipe 27, communicating with the bottom of the electroplating tank 1, is fixedly connected to the side of the electroplating tank 1. A valve 28 is installed on the drain pipe 27. A liquid passage groove 29 is provided at the bottom of each partition 2 to facilitate the discharge of electroplating solution from the multiple electroplating tanks 3, allowing for easy replacement of the electroplating solution. A base plate 4 is fixedly connected to the side of the electroplating tank 1 at a position corresponding to the multiple electroplating tanks 3. A square tube 5 is fixedly connected to the top of the base plate 4. A lifting column 6 is slidably installed inside the square tube 5. A fixing block 7 is fixedly connected to the side of the lifting column 6. An electric cylinder 8 is fixedly connected between the fixing block 7 and the base plate 4. A crossbar 9 is fixedly connected to the side of the lifting column 6. A reinforcing plate 26 is fixedly connected to the top of the crossbar 9. The side of the reinforcing plate 26 is connected to the lifting column. The side end of the crossbar 9 is fixedly connected to improve the stability of the connection between the crossbar 9 and the lifting column 6. The bottom end of the crossbar 9 is detachably connected to two lifting components. The bottom end of the two lifting components is fixedly connected to a fixed frame 10. Multiple fixing parts 11 are evenly fixedly connected to the top of the inside of the fixed frame 10. By setting multiple fixing parts 11, it is convenient to suspend the battery busbar on the corresponding fixing parts 11 according to the usage requirements. It is convenient to adjust the spacing between adjacent battery busbars and to control the number of battery busbars suspended on the fixed frame 10. The side end of the fixing part 11 is provided with an L-shaped groove 24. The fixing part 11 is provided with a through groove 25 that communicates with the L-shaped groove 24 for suspending copper wires. It is convenient to insert the copper wire on the battery busbar into the inside of the L-shaped groove 24 first, and then put the copper wire into the through groove 25. During the electroplating process of the battery busbar, it is prevented that the copper wire falls out of the inside of the through groove 25. The crossbar 9 is provided with a positioning component.

[0023] Specifically, the electric cylinder 8 drives the lifting column 6 and the crossbar 9 to move up and down, facilitating the descent of the fixed frame 10 and the multiple battery busbars suspended on it, and facilitating the lifting of the electroplated battery busbars to the upper side of the electroplating tank 1. By setting multiple crossbars 9, it is easy to control multiple fixed frames 10 individually, and to electroplat the battery busbars on multiple fixed frames 10. During the electroplating process of some fixed frames 10, it is easy to disassemble the fixed frame 10 with the electroplated battery busbars, and to disassemble and replace the battery busbars on the fixed frame 10, which can ensure the continuity of battery busbar electroplating and improve the efficiency of battery busbar electroplating.

[0024] Please see Figures 1-4The bottom end of the crossbar 9 is provided with a convex groove 12, and a convex plate 13 is inserted into the convex groove 12. The bottom end of the convex plate 13 is fixedly connected to two lifting components. After the convex plate 13 is inserted into the convex groove 12, the front end face of the convex plate 13 is flush with the front end face of the crossbar 9, which facilitates the disassembly and assembly of the fixed frame 10. The lifting components include two vertical columns 14, and the bottom end of each of the two vertical columns 14 is provided with an adjustment groove 15. A lifting rod 16 is slidably arranged inside each of the two adjustment grooves 15. The side end of the vertical column 14 is threadedly connected with a first screw 17 that cooperates with the lifting rod 16, which facilitates the adjustment of the height of the fixed frame 10.

[0025] Specifically, the convex plate 13 is inserted into the convex groove 12 and connected to the crossbar 9, which facilitates the disassembly and assembly of the fixed frame 10. The lifting rod 16 slides inside the adjusting groove 15, which facilitates the adjustment of the height between the fixed frame 10 and the crossbar 9, and the adjustment of the distance between the battery busbar suspended on the fixed frame 10 and the crossbar 9. When the crossbar 9 is at its lowest point, the height of the battery busbar is adjusted, which facilitates the appropriate adjustment of the height of the fixed frame 10 and the battery busbar according to the amount of electroplating liquid inside the electroplating tank 3, and at the same time, it facilitates the complete immersion of battery busbars of different heights in the electroplating liquid.

[0026] Please see Figure 1 , Figure 2 and Figure 5 The positioning component includes an L-shaped plate 18, which is fixedly connected to the top of the crossbar 9. A square post 19 is slidably mounted on the L-shaped plate 18. A positioning seat 20 is fixedly connected to the bottom of the square post 19. The side end of the positioning seat 20 contacts the side end of the crossbar 9. A compression spring 21 is provided between the positioning seat 20 and the L-shaped plate 18. The compression spring 21 is sleeved on the outside of the square post 19. A top plate 22 is fixedly connected to one end of the square post 19 extending above the L-shaped plate 18, which positions the convex plate 13 inside the convex groove 12. This prevents the convex plate 13 from sliding out of the convex groove 12 during the electroplating process of the battery busbar. The top plate 22 is fixedly connected to the square post 19 by a second screw 23, which facilitates the disassembly of the top plate 22 and the replacement of the compression spring 21.

[0027] Specifically, by setting a positioning component, before inserting the convex plate 13 into the convex groove 12, the convex plate 13 pushes the positioning seat 20 upward, and then inserts the convex plate 13 into the convex groove 12. When the convex plate 13 is fully inserted into the convex groove 12, the front end face of the convex plate 13 is flush with the front end face of the crossbar 9. At this time, the compression spring 21 pushes the positioning seat 20 downward, so that the positioning seat 20 blocks one side of the convex groove 12, thus preventing the convex plate 13 from sliding out of the convex groove 12 during the electroplating process of the battery busbar.

[0028] In summary, when using the overall equipment: The copper wires on the battery busbars are hung inside the through slots 25 on the corresponding fixing parts 11. Then, the positioning seat 20 is pushed upward by the convex plate 13. The convex plate 13 is then inserted into the convex groove 12. When the convex plate 13 is fully inserted into the convex groove 12, the front end face of the convex plate 13 is flush with the front end face of the crossbar 9. At this time, the positioning seat 20 is pushed downward by the compression spring 21, so that the positioning seat 20 blocks one side of the convex groove 12 to position the convex plate 13. Then, the fixing block 7 and the lifting column 6 are pulled downward by the electric cylinder 8, so that the fixing frame 10 and multiple battery busbars are moved into the electroplating solution inside the corresponding electroplating tank 3 to perform electroplating treatment on the battery busbars.

[0029] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
