[0002] With increasing global emphasis on environmental protection and sustainable development, new energy vehicles, as a green and efficient mode of transportation, are gradually becoming the development direction of the automotive industry. One of the core components of new energy vehicles is the battery system, and the battery busbar plays a crucial role in this system. It is responsible for connecting the individual battery cells in the battery module, realizing the transmission and distribution of electrical energy, and its performance directly affects the safety, stability, and charging / discharging efficiency of the battery system.

[0003] Welding is a critical process in the manufacturing of conductive busbars for new energy vehicle batteries. Since conductive busbars are typically made of metals such as copper and aluminum, these metals readily react with oxygen in the air to form an oxide layer. The presence of this oxide layer increases the resistance at the weld joint, reduces energy transfer efficiency, and may even lead to localized overheating, affecting the performance and safety of the battery system. Therefore, before welding, the weld joints of the conductive busbars must be ground to remove the oxide layer and ensure good weld quality. New energy vehicle battery conductive busbars come in various shapes and sizes to meet the design requirements of different battery modules. Currently, fixing these differently shaped conductive busbars in the appropriate position during manual grinding is a challenge. Therefore, new research is needed on how to fix conductive busbars effectively. Utility Model Content

[0016] Compared to existing ESB grinding methods, this invention provides automatic grinding for the welded parts of ESBs. It employs a composite positioning structure of telescopic positioning pin array and positioning steps. The densely distributed telescopic positioning pins form an adaptive positioning zone, compatible with L-shaped, T-shaped, and other irregularly shaped ESBs. The positioning steps and the grinding end face of the ESB form a reference support, and the linear pressure from the clamping positioning module ensures that the relative positional tolerance between the ESB to be ground and the grinding device is controlled within ±0.05mm. This three-level positioning system effectively solves the problem of insufficient rigidity in thin-walled ESBs during grinding. The Y-axis transmission module drives the fixed platform to achieve axial feed, which, combined with the radial adjustment of the grinding device, forms a two-dimensional motion compensation mechanism. When removing a 0.2-0.5mm thick oxide layer, the system can automatically compensate for the grinding trajectory according to the actual contour of the ESB, avoiding uneven grinding caused by workpiece shape and position tolerances. The telescopic positioning pins and positioning steps within the ESB fixing fixture work together to form a multi-dimensional precise positioning system for the ESB. The construction of dense positioning zones ensures effective fixation of the complex-shaped outer surface of the busbar, preventing displacement or shaking during grinding and thus guaranteeing grinding accuracy and consistency. The positioning steps are specifically designed for positioning the part of the busbar to be ground, making the grinding operation more precise and efficient. The clamping positioning module enhances the stability of the busbar during grinding. By clamping and fixing the busbar close to the part being ground onto the positioning steps, deformation or displacement caused by grinding force is effectively prevented, ensuring grinding quality and efficiency. This invention improves the efficiency and quality of the grinding process before welding new energy busbars through precise positioning capabilities, efficient grinding performance, and a high level of automation.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-7As shown, in one embodiment of this utility model, an automatic grinding mechanism for conductive busbars in new energy vehicles is disclosed. The mechanism includes a base 1, a column 2, a worktable 3, two sets of busbar fixing devices 4, and a busbar grinding device 5. The column 2 is disposed on one side of the base 1, and the worktable 3 is disposed on the other side of the base 1, with the column 2 and worktable 3 facing each other. The busbar fixing devices 4 are disposed on the worktable 3, and the busbar grinding device 5 is disposed on the column 2, forming a grinding station between the busbar grinding device 5 and the busbar fixing devices 4. The busbar fixing devices 4 include a Y-axis transmission module 41, a fixing platform 42, and a busbar fixing fixture 43. The Y-axis transmission module 41 is disposed on the worktable 3, and the fixing platform 42 is disposed on the Y-axis transmission module 41. The busbar fixing fixture 43 is mounted on the fixed platform 42. The fixture 43 includes a fixed base plate 431, telescopic positioning pins 432, positioning steps 433, and a clamping positioning module 434. Multiple telescopic positioning pins 432 are evenly distributed on the fixed base plate 431, forming a dense positioning area to position the outer surfaces of busbars of different shapes. The positioning steps 433 are located at one end of the fixed base plate 431 and face the busbar grinding device 5 for positioning the part of the busbar to be ground. The multiple telescopic positioning pins 432 are used for positioning the rear end shape of the busbar. The clamping positioning module 434 is used to press and fix the busbar close to the part to be ground onto the positioning steps 433. This embodiment is used for automatic grinding of the busbar welding section, employing a composite positioning structure of telescopic positioning pin array 432 and positioning steps 433. The densely distributed telescopic positioning pins 432 form an adaptive positioning area, compatible with the clamping and positioning of L-shaped, T-shaped, and other irregularly shaped busbars.

The three-level positioning system effectively solves the problem of insufficient rigidity of thin-walled electric busbars during the grinding process. The Y-axis transmission module 41 drives the fixed platform 42 to achieve axial feed, and with the radial adjustment of the grinding device, a two-dimensional motion compensation mechanism is formed. When removing a 0.2-0.5mm thick oxide layer, the system can automatically compensate for the grinding trajectory according to the actual contour of the electric busbar, avoiding uneven grinding caused by workpiece shape and position tolerances. The telescopic positioning pin 432 in the electric busbar fixing fixture 43 works in conjunction with the positioning step 433 to form a multi-dimensional precise positioning system for the electric busbar. The construction of dense positioning areas ensures effective fixation of the outer surface of the complex-shaped electric busbar, avoiding displacement or shaking during the grinding process, thereby ensuring grinding accuracy and consistency. The positioning step 433 is specifically designed for positioning the part of the electric busbar that is being ground, making the grinding operation more precise and efficient. The clamping positioning module 434 enhances the stability of the electric busbar during the grinding process.By pressing and fixing the electric busbar close to the part being polished onto the positioning step 433, deformation or displacement caused by polishing force is effectively prevented, ensuring polishing quality and efficiency. The precise positioning capability, efficient polishing performance, and high level of automation in this embodiment improve the efficiency and quality of the polishing process before welding new energy electric busbars.

[0028] The base 1 and the column 2 form an L-shaped frame structure. An X-axis drive module 21 is mounted on the column 2, and a Z-axis drive module 22 is mounted on the X-axis drive module 21. The electric arc polishing device 5 is mounted on the Z-axis drive module 22. The X-axis drive module 21 and the Z-axis drive module 22 cooperate to drive the electric arc polishing device 5 to move towards the electric arc plate fixed on the electric arc plate fixing device 4 for polishing. In this embodiment, the L-shaped frame structure formed between the base 1 and the column 2 ensures stability and support. The X-axis drive module 21 on the column 2, with its high-precision transmission characteristics, ensures the accuracy of the polishing path. The deployment of the Z-axis drive module 22 on the X-axis drive module 21 enables fine control of the polishing depth, greatly enhancing the flexibility and adaptability of the polishing operation. The electric busbar grinding device 5 is mounted on the Z-axis drive module 22. Through the coordinated operation of the X-axis and Z-axis drive modules 22, it can precisely move towards the electric busbar securely clamped on the electric busbar fixing device 4 to perform the grinding task. It plays a key role in the pretreatment stage before welding of new energy electric busbars, effectively removing the oxide layer on the surface of the electric busbar, creating ideal process conditions for subsequent welding operations, thereby ensuring welding quality and the overall performance of the electric busbar.

[0029] A fixed substrate 431 is mounted on a fixed platform 42. The Y-axis transmission module 41 drives the fixed platform 42 to move towards the ESB grinding device 5, so that the ESB can be ground by the ESB grinding device 5. In this embodiment, the fixed substrate 431 is stably mounted on the fixed platform 42, providing reliable and stable support for the entire grinding operation and avoiding grinding accuracy deviations caused by structural loosening during the grinding process. The Y-axis transmission module 41 precisely drives the fixed platform 42 to move towards the ESB grinding device 5, achieving precise control of the ESB grinding position. This allows the ESB to contact the grinding device in the right posture, ensuring that the grinding force is applied evenly and stably to the ESB surface. The transmission and positioning method can efficiently and thoroughly complete the grinding task by removing the oxide layer on the ESB surface, ensuring that the oxide layer is completely removed, thereby greatly improving the quality of subsequent ESB welding and effectively reducing welding defects that may be caused by residual oxide layer.

[0030] See Figures 5-7As shown, at least two sets of E-bus fixing devices 4 are provided, and at least two sets of E-bus fixing devices 4 are arranged side by side on the worktable 3 for alternating or corresponding use with E-bus products of different shapes. A tail support 31 is provided behind the E-bus fixing devices 4 on the worktable 3, which supports the tail of the E-bus. In this embodiment, E-bus products of different shapes can be used alternately or correspondingly, enhancing the applicability and flexibility of the polishing mechanism. Facing diverse E-bus product shapes, there is no need to frequently change the entire fixing device, efficiently completing the fixing of E-buses of different shapes. The tail support 31 provided behind the worktable effectively supports the tail of the E-bus. During polishing, the E-bus, especially its tail, can maintain a stable posture, avoiding positional shifts or shaking caused by polishing force and other factors, thereby ensuring polishing accuracy and consistency, and effectively improving the quality and efficiency of the entire E-bus oxide layer removal polishing process.

[0031] The fixed base plate 431 has evenly distributed mounting holes 4311. The telescopic positioning pin 432 includes a fixed sleeve 4321 and a telescopic rod 4322. The fixed sleeve 4321 is disposed within the mounting holes 4311, and the telescopic rod 4322 is movably disposed within the fixed sleeve 4321. The fixed sleeve 4321 is provided with a telescopic spring 4323 for the telescopic movement of the telescopic rod 4322. A limit step is provided within the fixed sleeve 4321 for limiting the movement of the telescopic rod 4322. In this embodiment, the evenly distributed mounting holes 4311 on the fixed base plate 431, in conjunction with the telescopic positioning pin 432, enable precise positioning and stable installation of related grinding components or other components. The fixed sleeve 4321 of the telescopic positioning pin 432 is disposed within the mounting holes 4311, ensuring the compactness of the overall structure and the reliability of the connection. The telescopic rod 4322 can move within the fixed sleeve 4321, and the telescopic spring 4323 allows it to flexibly adapt to different working conditions during the grinding process. During grinding operations, the telescopic state can be automatically adjusted according to actual needs, ensuring positioning accuracy while buffering potential external impacts. The limiting step inside the fixed sleeve 4321 acts as a limit for the movement of the telescopic rod 4322, effectively preventing excessive extension or retraction of the telescopic rod 4322 that could lead to structural damage or positioning failure, greatly improving the stability and reliability of the entire automatic grinding mechanism for the conductive busbar of new energy vehicles.

[0032] Multiple telescopic positioning pins 432 are used to adapt to the different shapes of the outer surface of the electric substation for positioning. The telescopic positioning pins 432 are hexagonal in shape and are evenly distributed in a honeycomb pattern. In this embodiment, the hexagonal telescopic positioning pins 432 can form a more stable and precise fit with the outer surface of the electric substation, effectively preventing displacement or shaking of the electric substation during the polishing process, ensuring the accuracy of the polishing position, and thus guaranteeing the consistency of polishing quality. Secondly, the multiple honeycomb-shaped telescopic positioning pins 432 can adapt to the various outer surface shapes of the electric substation in all directions. Whether the shape is regular or irregular, reliable positioning can be achieved, greatly improving the compatibility of this automatic polishing mechanism with different models and specifications of new energy electric substations.

[0033] The clamping and positioning module 434 includes a clamping cylinder 4341 and a fixing block 4342. The clamping cylinder 4341 drives the fixing block 4342 to move toward the positioning step 433 to clamp and fix the busbar. The fixing block 4342 is provided with a first positioning groove 4343, and the positioning step 433 is provided with a second positioning groove 4331. The first positioning groove 4343 and the second positioning groove 4331 mate to form a positioning slot to clamp and fix the shape of the busbar. A tungsten carbide positioning block is inlaid on the outer periphery of the positioning slot to fix the busbar. In this embodiment, by driving the fixing block 4342 toward the positioning step 433 to clamp the busbar, the clamping cylinder 4341 can ensure that the busbar remains in a stable fixed state during the grinding process, effectively avoiding problems such as uneven grinding or deviation caused by busbar displacement, and ensuring grinding accuracy. The first positioning groove 4343 and the second positioning groove 4331 on the fixing block 4342 engage to form a positioning slot, which can accurately fit and press the busbar according to its shape, so that the busbar is firmly fixed in a specific position. The tungsten carbide positioning block inlaid on the outer periphery of the positioning slot further enhances the fixing effect on the busbar, restricting the movement of the busbar from multiple angles, so that the busbar can always maintain an accurate posture during the grinding operation to remove the oxide layer.

[0034] The electro-hydraulic busbar polishing device 5 includes a mirror drive module 51, a polishing drive module 52, and a dust collection module 53. Two sets of polishing drive modules 52 are arranged opposite each other and mounted on the mirror drive module 51. The mirror drive module 51 drives the two sets of polishing drive modules 52 to move relative to each other in a mirror image for polishing both sides of the electro-hydraulic busbar. The dust collection module 53 is located outside the polishing drive module 52 to collect dust generated during the polishing process. Specifically, the driving end of the polishing drive module 52 is equipped with a polishing wheel 521, and the outer periphery of the polishing wheel 521 is equipped with a dust cover 522. The dust collection module 53 is equipped with a dust collection pipe 531, one end of which is connected to the dust cover 522. The polishing wheel 521 is a fiber mesh wheel or a mesh wheel with alloy fibers, used to polish the aluminum busbar to create a rough surface at the welded ends. In this embodiment, the mirror drive module 51 drives two grinding drive modules 52 to move in a mirror-like relative manner, enabling efficient and precise simultaneous grinding of both sides of the busbar, greatly improving grinding efficiency, ensuring the consistency of grinding on both sides of the busbar, and effectively removing the oxide layer. The fiber mesh wheel or alloy fiber mesh wheel in the grinding drive module 52 can specifically grind the aluminum busbar, forming a rough surface at the weld end that meets the requirements, enhancing the bonding force during welding. The connection between the dust collection module 53 and its dust collection pipe 531 and the dust cover 522 on the outer periphery of the grinding wheel 521 can timely and effectively absorb the dust generated during the grinding process, keeping the working environment clean, avoiding adverse effects of dust on the busbar and grinding equipment, ensuring the continuous and stable operation of the grinding work and the grinding quality of the busbar.
