Description

Technical Field

[0001] This invention belongs to the field of battery manufacturing and processing technology, and in particular relates to a fully automatic cutting and forming device for battery busbars. Background Technology

[0002] In the manufacturing process of batteries, especially lead-acid batteries, multiple individual cells (or "cells") are connected in series or parallel via metal connecting strips to form a battery pack with a specific voltage and capacity. These metal strips, which serve the functions of conduction and structural connection, are called "buses". In a typical manufacturing process, the battery case (containing multiple individual cells) is usually inverted when entering the busbar welding and subsequent processing station. At this point, the busbar, which has been preliminarily cast or welded to the battery terminals, will protrude from the bottom plane of the case. It needs to be precisely cut and shaped according to product specifications to remove excess material, separate connection points, and form the final electrical connection structure.

[0003] Traditional busbar cutting and forming mainly relies on manual labor or semi-automatic equipment, which has many drawbacks. First, manual operation using handheld cutting tools is labor-intensive, inefficient, and results in inconsistent cutting dimensions. It heavily depends on the operator's experience and skill, leading to significant fluctuations in product quality. Second, the metal shavings and dust generated during the cutting process are prone to flying, posing safety hazards and potentially contaminating the battery's internal structure, affecting its final performance and lifespan. Furthermore, frequent manual handling and repositioning increase the risk of damage to the battery casing (especially plastic casings) due to impacts.

[0004] To improve automation, some specialized cutting equipment has emerged in the industry. However, these existing solutions often suffer from limited functionality and fragmented process flows. For example, cutting the ends of a busbar and separating the middle section are usually performed on different equipment or at different stations, requiring multiple loading and unloading operations and repeated positioning. This not only increases the equipment's footprint and overall investment cost, but also leads to accumulated errors due to repeated handling and positioning, making it difficult to guarantee cutting accuracy. The final formed size of the busbar may exceed the tolerance range. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention aims to provide a fully automatic cutting and forming device for battery busbars. This device is highly integrated and automated, and can seamlessly connect the end forming and cutting of the busbar with the middle separation and cutting process, completing all cutting actions in continuous operation, thereby significantly improving production efficiency and reducing labor intensity and safety hazards.

[0006] To achieve the objectives of the invention described above, the present invention adopts the following technical solution:

[0007] A fully automatic cutting and forming device for battery busbars includes a frame, an end cutting mechanism, a middle cutting mechanism, and a material transfer mechanism, wherein the end cutting mechanism, the middle cutting mechanism, and the material transfer mechanism are all mounted on the frame.

[0008] The end cutting mechanism includes a saw blade and a cutting motor. A battery positioning plate is provided on the frame, and a protective plate is provided at the bottom of the battery positioning plate. The cutting motor drives the saw blade to rotate and cuts the two ends of the battery busbar exposed on the protective plate.

[0009] The middle cutting mechanism includes a cutting mold, a cutting tool assembly, and a lifting drive. The cutting mold is mounted on the frame. The material transfer mechanism inverts the battery processed by the end cutting mechanism onto the cutting mold. The cutting mold has a through-hole for the cutting tool. The lifting drive drives the cutting tool assembly to move up and down, so that the cutting head in the cutting tool assembly passes through the through-hole to cut the busbar.

[0010] The aforementioned structure integrates the two core processes of "end cutting" and "middle cutting" onto a single device (frame), connected by a "material transfer mechanism," enabling continuous operation from feeding at one end to discharging at the other. This fundamentally solves the problems of fragmented processes and the need for multiple handling and positioning required in traditional manufacturing, significantly shortening the production cycle and improving overall production efficiency. Furthermore, by setting up dedicated positioning structures ("battery positioning plate" and "cutting mold") for each of the two cutting stations, it ensures that the battery is precisely fixed at each critical processing stage. In particular, the design of the "protective plate" protects the battery body, preventing metal debris from entering the battery, and limits the cutting range at the busbar end. The "tool through hole" precisely guides the tool path. The middle cutting process abandons the traditional saw blade cutting method, using stamping or pulling to cut the busbar, avoiding the generation of metal debris and improving the yield rate of battery production. The above structure ensures the relative positional accuracy of the two cutting operations, resulting in high dimensional consistency of the final busbar and stable product quality.

[0011] As a preferred embodiment, the battery loading mechanism and battery unloading mechanism are located at both ends of the end cutting mechanism and the middle cutting mechanism, respectively. The material transfer mechanism includes a lateral moving component, a lifting component, and a clamping component. The lifting component is slidably mounted on the lateral moving component, and the clamping component is fixed on the lifting component. There are multiple clamping components, which are fixed by a connecting beam. The multiple clamping components enable the batteries on the battery loading mechanism, the end cutting mechanism, and the middle cutting mechanism to be synchronously transferred to the next work station.

[0012] The aforementioned structure, by adding a "battery loading mechanism" and a "battery unloading mechanism," combined with the busbar cutting and processing unit and the material transfer mechanism, forms a complete closed-loop automated production line of "loading, processing, and unloading," achieving true "full automation" and further reducing manual intervention. Furthermore, the structure specifies that the "material transfer mechanism" adopts a multi-degree-of-freedom structure of "lateral movement, lifting, and clamping," and that "multiple clamping components" are fixed by "connecting beams" to achieve synchronous handling. The core effect of this design is the ability to simultaneously transfer batteries located at the loading position, end-cutting position, and middle-cutting position to the next adjacent workstation in one go. This "relay race" style synchronous transfer method minimizes material waiting and conveying time, which is key to achieving a high production cycle.

[0013] As a preferred embodiment, the battery positioning plate has an elongated through hole, the battery is placed upside down on the battery positioning plate, and the busbar passes through the elongated through hole.

[0014] As a preferred embodiment, the frame is further provided with a moving component, the cutting motor is fixed on the moving component, the saw blade is rotatably mounted on the top of the moving component and is driven to rotate by the cutting motor, and the moving component moves up, down, forward, backward and left and right in the frame so that the saw blade cuts both ends of multiple busbars.

[0015] As a preferred embodiment, the moving component includes a bottom mounting plate, a connecting column A, a connecting column B, a first driving component, and a second driving component. The bottom mounting plate is fixed on the frame. The connecting column A is slidably mounted on the bottom mounting plate. The first driving component is mounted on the bottom mounting plate and drives the connecting column A to slide back and forth on the bottom plate. The connecting column B is slidably mounted on one end of the connecting column A. The second driving component is mounted on the connecting column A and drives the connecting column B to move up and down.

[0016] As a preferred embodiment, the connecting column B is a hollow column, the cutting motor is fixed on one side of the connecting column B, the output shaft of the cutting motor extends into the connecting column B, and the top of the connecting column B is provided with a rotatable shaft through a support seat and bearing. The shaft is driven by the cutting motor through gears, belts, synchronous belts or chains, and the two saw blades are respectively fixed at both ends of the shaft.

[0017] As a preferred embodiment, the cutting tool assembly includes a lifting plate, a power component, and a cutting blade. The cutting blade is slidably mounted on the lifting plate, and the power component is mounted on the lifting plate to drive the cutting blade to move along the width direction of the busbar.

[0018] As a preferred embodiment, the cutting blade includes a tool fixing block and a cutting head, the tool fixing block has a mounting opening at the top, and the cutting head is inserted and fixed in the mounting opening.

[0019] As a preferred embodiment, the lifting plate is provided with mounting baffles at both ends, and multiple support rods are arranged in parallel between the two mounting baffles. The tool fixing block is slidably mounted on the support rods. The power component is a drive cylinder, and at least one mounting baffle is fixed with a drive cylinder. The drive cylinder is connected to the tool fixing block and drives the tool fixing block to move along the width direction of the busbar.

[0020] As a preferred embodiment, the cutting blades on the lifting plate are in multiple sets, and each set of cutting blades includes a blade fixing block A and a blade fixing block B. The blade fixing block A and the blade fixing block B are located on both sides of the two busbars, respectively. The blade head is fixed on the upper part of the blade fixing block A and the blade fixing block B, and the position of the blade head corresponds to the cutting position on the two busbars of each battery.

[0021] As a preferred embodiment, the frame is further provided with a lifting and movable support plate, which is located above the cutting mold. The support plate has a positioning hole, the battery is inverted on the support plate, and the busbar passes through the positioning hole.

[0022] As a preferred embodiment, both the end cutting mechanism and the middle cutting mechanism include a mounting plate, which is fixed to the frame. The mounting plate has a through hole to facilitate the passage of the battery, and the mounting plate is also provided with a battery clamping assembly.

[0023] As a preferred embodiment, the battery clamping assembly includes clamping plates, guide rail A, and pneumatic grippers. The guide rail A is fixed to the mounting plate or the battery positioning plate. The clamping plates are slidably disposed on the guide rail A and are located at both ends of the battery in the length direction. The pneumatic grippers are fixed to the lower part of the mounting plate or the battery positioning plate, and the two movable parts of the pneumatic grippers are respectively fixed to the ends of the two clamping plates, driving the two clamping plates to move closer to each other or further apart, so that the battery is clamped and fixed or released.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] The entire cutting process of this invention is automatically completed by a mechanism, including saw blade rotation, tool punching, and battery station transfer. This significantly reduces reliance on manual operation, lowers labor intensity, and provides a protective plate for the saw blade cutting station. The middle cutting utilizes punching or pulling to sever the busbar, protecting the battery body and preventing metal debris from entering the battery, thus improving the battery yield. Furthermore, isolating operators from the high-speed rotating saw blade and punching tool significantly enhances production safety and reduces human error. Attached Figure Description

Unless otherwise specified, 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 application pertains.

[0044] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0045] Furthermore, in the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0046] 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 this invention, unless otherwise stated, "a plurality of" means two or more, unless explicitly defined otherwise.

[0047] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0050] like Figures 1 to 4As shown, a fully automatic cutting and forming device for battery busbars includes a frame 1, an end cutting mechanism 2, a middle cutting mechanism 3, a material transfer mechanism 4, a battery loading mechanism 5, and a battery unloading mechanism 6. The battery loading mechanism 5, end cutting mechanism 2, middle cutting mechanism 3, and battery unloading mechanism 6 are all mounted on the frame 1 and arranged sequentially from one end of the frame 1 to the other. The material transfer mechanism 4 is located in the frame 1, with its main body positioned above the end cutting mechanism 2 and the middle cutting mechanism 3, and its two ends positioned above the battery loading mechanism 5 and the battery unloading mechanism 6. The battery loading mechanism 5 and the battery unloading mechanism 6 have the same structure, both including a bracket, a loading / unloading motor, and a transmission chain. The loading / unloading motor is mounted on the bracket and drives multiple transmission chains to rotate via a long shaft. The battery 7 is placed on two spaced-apart transmission chains and is moved by the transmission chains. The above structure can meet the requirements of inverted battery transfer. The dual drive chain supports both sides of the bottom of the battery, allowing the tabs in the middle of the battery to be exposed, which facilitates subsequent processing.

[0051] The battery feeding mechanism 6 can also be equipped with a battery flipping mechanism, which makes it easy to flip the inverted battery so that the busbar faces upward before conveying it to the next process. The battery flipping mechanism adopts the form of a motor-driven rotating shaft, and the rotating shaft is equipped with a gripping frame. The gripping frame is flipped back and forth under the drive of the rotating shaft. The battery flipping mechanism can also adopt the form of a robot arm or the like.

[0052] like Figures 5 to 9 As shown, the end cutting mechanism 2 includes a mounting plate 11, a moving component, a saw blade, and a cutting motor 271. The mounting plate 11 has a through hole for the battery 7 to pass through. A battery positioning plate 13 is fixed to the lower part of the mounting plate 11. The battery positioning plate 13 has an elongated through hole 131 for the busbar 71 to pass through. The battery 7 is inverted on the battery positioning plate 13, and the busbar 71 protrudes through the elongated through hole 131. A protective plate 14 is fixed to the lower part of the elongated through hole 131. The protective plate 14 covers most of the battery and the busbar 71, exposing only the two ends of the busbar 71, which extend beyond the battery casing. The saw blade is located below the battery positioning plate, and the cutting motor is mounted on the frame. The cutting motor drives the saw blade to rotate, cutting the two ends of the busbar.

[0053] The battery positioning plate and its elongated through-holes provide a stable and uniform mounting reference for the inverted battery. The busbars, emerging from the through-holes at specific locations, naturally define the initial position of the cutting line, reducing errors caused by manual marking or visual inspection. This provides a fundamental guarantee for subsequent precise and consistent cutting. Concentrating the cutting operation area from the entire battery pack to the two ends of the two narrow slits exposed on the battery positioning plate (the two ends of the busbars) makes the cutting action target clear and the path fixed, creating conditions for subsequent automated and programmed cutting, while also maximizing battery protection.

[0054] The above structure combines a battery positioning plate and a protective plate, and inverts the battery so that the busbar hangs down naturally to the working area. The protective plate completely covers the battery casing, tabs and other key parts, leaving only the two ends of the busbar to be cut exposed. This is equivalent to establishing a "physical firewall" between the high-speed cutting saw blade and the battery body, completely blocking the possibility of metal chips, sparks and other debris generated during cutting directly splashing or coming into contact with the battery, thus eliminating major safety hazards such as short circuits, pollution and burns from the root.

[0055] like Figure 6 As shown, the mounting plate 11 is also provided with a battery clamping assembly, which includes a clamping plate 123, a guide rail A124, and a pneumatic gripper 125. The guide rail A124 is fixed on the mounting plate, the clamping plate 123 is slidably disposed on the guide rail A124, and the clamping plate 123 is located at both ends of the through hole in the length direction. The pneumatic gripper 125 is fixed to the lower part of the mounting plate, and the two movable parts of the pneumatic gripper 125 are respectively fixed to the ends of the two clamping plates 123, driving the two clamping plates 123 to move closer to each other or further away from each other, thereby realizing the clamping and fixing or the release of the battery 7.

[0056] Pneumatic grippers drive two clamping plates to move synchronously towards each other along a guide rail, enabling automated and rapid battery clamping and release. The pneumatic system offers ample power, rapid action, and simple control. Reliable clamping is a prerequisite for precision cutting; it completely eliminates any displacement of the battery under cutting vibration, ensuring that the landing point of each cut is perfectly consistent with the program settings. This is a key factor in guaranteeing cutting accuracy for mass production.

[0057] The mounting plate 11 has four through holes, allowing for the simultaneous insertion of four batteries. Three guide rails A124 are arranged parallel to the length of the through holes. Two clamping plates 123 are set perpendicular to the guide rails A124. The three guide rails A124 support the middle and both ends of the clamping plates 123 respectively. Multiple convex-shaped protrusions are also spaced apart on opposite sides of the two clamping plates 123. These protrusions limit the length and width of the batteries 7, ensuring stable battery clamping.

[0058] The pneumatic gripper 125 is fixed to the clamping plate 123 via a connecting block 122. The mounting plate 11 has an elongated hole for the movement of the movable part of the pneumatic gripper 125. One end of the connecting block 122 is fixed to the top of the movable part of the pneumatic gripper 125, and the other end is fixed to the end of the clamping plate 123. Preferably, the end of the connecting block 122 has two protrusions spaced apart, forming a groove between them, and the end of the clamping plate 123 is engaged in the groove. Connecting via the connecting block across the elongated hole on the mounting plate / battery positioning plate allows the pneumatic gripper to be installed in a more concealed, protected lower or side position, reducing the space occupied above and the complex exposed piping, resulting in a cleaner and safer overall layout. Simultaneously, this connection method typically provides a better lever arm, making the transmission of clamping force more direct and efficient, and reducing deformation of the connecting components.

[0059] The mounting plate 11 is fixed with an upper cover plate 121 for covering the guide rail A124, the clamping plate and the connecting block. The upper cover plate 121 protects the above-mentioned components.

[0060] like Figure 8 and Figure 9 As shown, the moving component is mounted on the frame, the cutting motor 23 is fixed on the moving component, and the saw blade 29 is rotatably mounted on the top of the moving component and is driven to rotate by the cutting motor 23. The moving component moves up, down, forward, backward, left and right in the frame 1, so that the saw blade 29 cuts both ends of multiple busbars 71.

[0061] In the aforementioned structure, a moving component drives the cutting motor and saw blade to move in three-dimensional space (up and down, forward and backward, left and right), enabling them to automatically position themselves at each busbar end on the battery pack that needs to be cut. This completely replaces the inefficient operation mode of manually moving batteries or manually adjusting the saw blade position, achieving continuous and automated batch processing and improving processing efficiency by orders of magnitude. Furthermore, mechanically driven movement offers higher repeatability and motion stability than manual operation. This ensures that the cutting length, kerf angle, and surface quality of all busbars in the same batch are highly consistent, significantly improving the standardization level and process reliability of product processing.

[0062] like Figure 8 and Figure 9 As shown, the moving component includes a bottom mounting plate 27, a connecting column A21, a connecting column B22, a first driving component, and a second driving component. The bottom mounting plate 27 is fixed on the frame 1. The connecting column A21 is slidably disposed on the bottom mounting plate 27. The first driving component is disposed on the bottom mounting plate and drives the connecting column A21 to slide back and forth on the bottom plate. The connecting column B22 is slidably disposed at one end of the connecting column A21. The second driving component is disposed on the connecting column A21 and drives the connecting column B22 to move up and down.

[0063] The aforementioned structure employs a modular, hierarchical transmission structure with a rational mechanical transmission path, facilitating manufacturing, assembly, and maintenance. Connecting column A is responsible for forward and backward feeding (typically corresponding to the width and length of the battery), while connecting column B is responsible for up and down movement (cutting in and out), providing a reliable mechanical basis for precise control of cutting depth and position.

[0064] The connecting column B22 is a hollow column. The cutting motor 23 is fixed to one side of the connecting column B22. The output shaft of the cutting motor 23 extends into the connecting column B22, and a synchronous pulley is fixed on the output shaft of the cutting motor 23. A rotatable shaft 28 is provided at the top of the connecting column B22 through a support seat and bearing. A synchronous pulley is fixed in the middle of the shaft 28. The shaft and the output shaft of the cutting motor are connected by a synchronous belt 210, thereby enabling the cutting motor 23 to drive the shaft 28 to rotate. Saw blades 29 are fixed at both ends of the shaft 28. The distance between the two saw blades 29 is slightly greater than the length of the protective plate 14. This ensures that the two saw blades 29 can completely cover and cut to the outermost end of the busbar when moving, without leaving any uncut "dead corners" due to the obstruction of the protective plate. At the same time, it also avoids collisions between the saw blades and the protective plate.

[0065] The cutting motor is positioned on one side of the hollow connecting column B, and power is transmitted to the top rotating shaft via an internal transmission mechanism (gears / belts, etc.). This fully utilizes the internal space of the column, resulting in a compact overall structure and reducing the lateral space occupied by the equipment. Simultaneously, the dual saw blades are coaxially arranged and driven by a single motor, enabling synchronous cutting of both ends of a busbar in a single operation. This achieves extremely high efficiency and ensures absolute synchronicity of the cutting actions at both ends. Furthermore, the rotating shaft is mounted on top of the connecting column B via a support base and bearings. This design provides strong rotational support rigidity, effectively resisting radial and axial forces during cutting, preventing saw blade vibration, resulting in a smoother cut and extended saw blade life.

[0066] In other embodiments, the number of saw blades 29 can be one. When the number of saw blades 29 is one, a third drive assembly needs to be added to drive the connecting post A21 and / or the connecting post B22 to move left and right to meet the cutting of both ends of the busbar.

[0067] The first drive assembly comprises a moving motor 271, a screw 272, and a nut 273. A guide rail B25 is fixed to the bottom mounting plate 27. A sliding plate 24 is fixed to the bottom of the connecting post A21, and the sliding plate 24 is slidably connected to the guide rail B25 via a slider. The nut 273 is fixed to the bottom of the sliding plate 24. The two ends of the screw 272 are rotatably mounted on the bottom mounting plate 27 via bearings and support seats, respectively. The nut 273 is fitted onto the screw 272. The moving motor 271 is mounted on the bottom mounting plate and drives the screw 272 to rotate via gears, belts, chains, etc., thereby moving the sliding plate. A cover A212 is also provided on the screw 272. The nut 273 is fixed to the connecting plate, and a connecting ear extends from at least one side of the connecting plate. The connecting ear is fixed to the bottom of the sliding plate and is located on one side of the cover A212. Adding a cover A to the screw effectively prevents metal dust and debris generated during cutting from falling into the threaded joint of the screw and nut. The above structure significantly improves the reliability, durability, and maintenance-free cycle of the transmission system.

[0068] The aforementioned structure employs a drive scheme consisting of a servo / stepper motor, ball screw, and guide rail. The ball screw drive offers extremely high positioning accuracy and smooth movement with virtually no backlash. Combined with a high-rigidity guide rail, it ensures precise millimeter- or even micrometer-level positioning of the cutting unit along the battery's length, as well as uniform, impact-free feed motion, which helps improve the cutting quality at the busbar end.

[0069] The second drive assembly uses a lifting cylinder A26. Assembly plates are fixed on the connecting column A and connecting column B respectively. The two assembly plates are also slidably connected by a guide rail and a slider. The cylinder body and piston rod of the lifting cylinder A26 are fixed to the two assembly plates respectively. When the lifting cylinder A26 moves, it drives the two assembly plates to move closer or separate, thereby realizing the lifting of the connecting column B. In other embodiments, the structures of the first drive assembly and the second drive assembly can be interchanged.

[0070] A lifting cylinder (usually a hydraulic cylinder or a high-performance pneumatic cylinder) is used as the vertical drive component. This type of component provides enormous linear thrust, ensuring that the saw blade has sufficient rigidity and holding force when cutting into hard metal manifolds, preventing "blade slippage". At the same time, its movement speed is adjustable and its response is rapid, enabling it to quickly complete the "descent-cutting-ascending" cycle, shortening the single cutting time.

[0071] In addition, when the saw blade 29 cuts the busbar 71, metal fragments will fly everywhere. To prevent the flying metal fragments from affecting the equipment, in this embodiment, a cover B211 is provided outside the rotating shaft 28, and a cover C is provided at the connection between connecting column B and connecting column A. At the same time, the bottom mounting plate 27, connecting column A21, first drive assembly and other components are placed on the lower side of the battery 7 and separated by a partition. The partition has movable holes and a bellows cover to further reduce the impact of metal fragments on the moving components. Adding covers to the rotating shaft (high-speed rotating component) and the moving joint (connection between connecting columns A and B) can prevent metal fragments and sparks generated during cutting from damaging the cutting device and affecting the service life of the equipment.

[0072] like Figure 17 As shown, after passing through the aforementioned end cutting mechanism, the busbar 71 welded to the tabs 72 on the electrode plate 70 of the battery 7 is cut off, making the overall length of the busbar less than the length of the battery casing.

[0073] like Figures 10 to 18 As shown, the middle cutting mechanism 3 includes a mounting plate 11, a support plate 321, a cutting mold 33, a fixing plate 34, a cutting tool assembly 31, and a hydraulic cylinder 30. The mounting plate 11 of the middle cutting mechanism and the mounting plate 11 of the end cutting mechanism have the same structure, and the two can be integrally formed or they can be two independent plates. The mounting plate 11 of the middle cutting mechanism is also provided with a battery clamping assembly, and its structure is the same as that of the battery clamping assembly of the end cutting mechanism.

[0074] The four corners of the fixed plate 34 are fixed to the mounting plate 11 by columns. The cutting mold 33 is fixed on the fixed plate 34. The cutting mold 33 has a through hole 331 for the tool aligned with the cutting position of the busbar 71. The hydraulic cylinder 30 is fixed to the lower part of the fixed plate 34. The cutting tool assembly 31 is slidably disposed on the lower part of the fixed plate 34, and its bottom is fixed to the piston rod of the hydraulic cylinder 30. The battery 7 is inverted on the mounting plate 11, so that the busbar 71 is located on the cutting mold 33. The hydraulic cylinder 30 drives the cutting tool assembly 31 to move up and down, thereby cutting the busbar 71. The cut busbar 71 and battery 7 are as follows: Figure 7 As shown.

[0075] The aforementioned structure, by setting up a dedicated cutting mold and a through-hole for the cutting tool, precisely aligning them with the cutting position of the inverted battery's busbar, fundamentally solves the core problems of poor positioning accuracy and inconsistent cuts encountered during manual operation or general equipment cutting. The lifting drive component drives the cutting tool assembly in vertical motion, providing stable and controllable power, enabling a one-time cut and significantly improving cutting efficiency and operational consistency. The entire cutting process abandons the traditional saw blade cutting method, utilizing stamping or drawing to cut the busbar, preventing metal debris from entering the battery and improving the yield rate of battery production.

[0076] like Figure 13 and Figure 14 As shown, the cutting tool assembly includes a lifting plate 311, a lateral movement force assembly, and a cutting blade. The cutting blade is slidably mounted on the lifting plate 311, and the lateral movement force assembly is mounted on the lifting plate 311 and drives the cutting blade to move along the width direction of the busbar. After the busbar is placed on the cutting mold, the power mechanism drives the cutting blade to move, so that the cutting blade is located below one or both sides of the busbar. Then, the hydraulic cylinder drives the lifting plate 311 to rise. After the cutting blade rises to a position higher than the busbar, the power mechanism drives the cutting blade to move directly above the busbar. Then, the hydraulic cylinder drives the lifting plate to descend, thereby causing the cutting blade to descend and cut the busbar.

[0077] The cutting blade includes a tool fixing block and a cutting head. The upper part of the cutting head 317 is shaped like a "7". The top of the tool fixing block is provided with an installation port. The lower part of the cutting head 317 is inserted and fixed in the installation port. The tool fixing block can be slidably mounted on the lifting plate 311 via a guide rail. In this embodiment, mounting baffles are provided at both ends of the lifting plate 311. Multiple support rods 313 are arranged in parallel between the two mounting baffles. The tool fixing block 316 is slidably mounted on the support rods 313. The power component is a drive cylinder 314. At least one mounting baffle is fixed with a drive cylinder 314. The drive cylinder 314 is connected to the tool fixing block and drives the tool fixing block to move along the width direction of the busbar.

[0078] The aforementioned structure designs the cutting blade to slide along the width of the busbar on the lifting plate, allowing it to extend between the tabs of the electrode plates and then pull the busbar off. This method of cutting outwards from the battery further reduces the risk of cut-off busbar waste falling into the battery. Furthermore, the lateral adjustment structure of the cutting blade allows for fine-tuning of the cutting position according to the actual width of the busbar or as needed, enhancing its adaptability to products of different specifications.

[0079] The cutter head and tool retaining block adopt a modular design with plug-in fixing, which facilitates quick replacement of worn cutter heads or adaptation to different cutter head shapes, reducing maintenance costs and time, and ensuring stable cutting quality over long-term use. Furthermore, the cutter head adopts a "7-shaped" structure; this hook-like or shouldered design helps to more effectively "bite" and separate the manifold during cutting, potentially resulting in better shearing or tearing effects, leading to cleaner cuts and reduced burr formation.

[0080] As a preferred embodiment, a gap hole 3311 is also provided on one side of the through hole of the cutting tool, and the busbar is located on the gap hole 3311. The width of the gap hole is smaller than that of the through hole of the cutting tool, which allows the cutting head to pass through while preventing the busbar from deforming during cutting.

[0081] like Figure 13 and Figure 14 As shown, in this embodiment, there are four sets of cutting blades. Each set of cutting blades includes a blade fixing block A315 and a blade fixing block B316. The blade fixing blocks A315 and B316 are located on both sides of the busbar. Two blade heads 317 are fixed at intervals on the top of the blade fixing block A315, and three blade heads 317 are fixed at intervals on the top of the blade fixing block B316. The positions of the blade heads 317 correspond to the cutting positions on the two busbars 71 of each battery 7, and the openings of the blade heads 317 on the blade fixing block A315 and the blade heads 317 on the blade fixing block B316 are arranged opposite to each other.

[0082] The aforementioned structure employs multiple sets of cutting blades, each set containing two opposing blade fixing blocks (A and B), and is equipped with a specific number of blade heads. This allows the device to simultaneously operate on multiple busbars or multiple cutting points, resulting in a significant increase in processing efficiency compared to single-point cutting. Furthermore, the blade heads can apply force simultaneously from both sides of the busbar, achieving pure shear cutting, greatly reducing busbar deformation and splashing, and producing high-quality cuts.

[0083] Four support rods 313 are arranged in parallel between the two mounting baffles. The tool fixing block A315 is slidably mounted on the two support rods 313 on both sides, and the tool fixing block B316 is slidably mounted on the two support rods 313 in the middle. The four tool fixing blocks A315 are fixed together in the middle by connecting rod A3151, and the two sides of the four tool fixing blocks B316 are fixed together by two connecting rods B3161 respectively. The two mounting baffles at both ends of the lifting plate 311 are respectively fixed with drive cylinders 314, one of which pushes the four tool fixing blocks A315 to move, and the other pushes the four tool fixing blocks B316 to move.

[0084] The aforementioned structure provides a sliding guide for the tool fixing block via a support rod, ensuring the straightness, stability, and high rigidity of the cutting blade during lateral movement. This effectively prevents blade wobbling or deviation during cutting, which is crucial for achieving high-precision, repetitive cutting. Using a drive cylinder (such as a pneumatic or hydraulic cylinder) as the power source provides fast response and high driving force, reliably driving the tool fixing block into position and maintaining it, thus improving the reliability and efficiency of the cutting action.

[0085] Furthermore, the aforementioned structure rigidly connects multiple identical tool fixing blocks into a single unit via connecting rods, and independent drive cylinders control two sets of tools, A and B, respectively, achieving absolute synchronous movement of tools within each set and independent controllability between sets. This design ensures consistency in the movement of all tool heads on the same side while allowing adjustment of the starting position or stroke of tools on both sides according to process requirements, offering extremely high flexibility. The precise support rod layout optimizes force distribution, ensuring overall structural stability and operational accuracy under simultaneous multi-tool operation.

[0086] Multiple support blocks 312 are also spaced apart on the lifting plate 311, and the support rod 313 passes through the corresponding support block 312. The addition of support blocks provides extra intermediate support points for the support rod, significantly enhancing its bending stiffness and vibration resistance. When subjected to cutting reaction force, it effectively suppresses the deflection of the support rod, thereby ensuring that the sliding trajectory of all tool fixing blocks remains accurate, further guaranteeing long-term cutting accuracy and device lifespan under multi-head, high-load conditions.

[0087] like Figure 11 As shown, the upper part of the fixing plate 34 is also provided with a support plate 321. The support plate 321 has a positioning hole. The housing of the battery 7 has a stepped surface. The edge of the positioning hole abuts against the stepped surface, so that the battery 7 is inverted on the support plate and the busbar 71 protrudes from the positioning hole. The lower part of the support plate 321 is fixed with a guide post 323. The fixing plate 34 is provided with a guide sleeve 324. The guide post 323 is slidably disposed in the guide sleeve 324. The lower part of the fixing plate 34 is also fixed with a lifting cylinder B322. The lifting cylinder B322 is fixed to the guide post 323 through a connecting rod. The lifting cylinder B322 drives the support plate 321 to rise and fall, so that the busbar 71 rests on or is removed from the cutting mold 33.

[0088] The lifting function of the support plate enables the "placement, positioning, lowering for cutting, and raising for removal" of the battery, facilitating automated loading and unloading. The liftable support plate allows the battery to slowly approach the cutting mold until the busbar is placed on the cutting mold, preventing damage to the busbar caused by direct placement of the battery on the cutting mold, which would affect the battery processing quality.

[0089] To ensure stable lifting and lowering of the support plate 321, two guide posts are spaced apart on each side of the support plate. These two guide posts are fixed by a connecting rod, and the piston rod of the lifting cylinder B322 is fixed to the middle of the connecting rod. Limiting posts 3211 are also provided on both sides of the positioning hole on the support plate 321, with the top of each limiting post 3211 being conical. The conical limiting posts serve as guides and provide initial positioning. When placing the battery, the conical surface easily guides the battery casing into the correct area, automatically correcting any slight positional deviation. This significantly reduces the difficulty of loading and the requirements for operational precision, while increasing loading speed, making it particularly suitable for use on fast-paced production lines.

[0090] like Figure 15 and Figure 16 As shown, the cutter head 317, driven by the hydraulic cylinder and the lateral movement force assembly, cuts the busbar, ultimately forming five cuts 73 on the busbar 71, as... Figure 18 As shown.

[0091] like Figure 2 As shown, the material transfer mechanism 4 includes a transverse component, a moving plate 43, a lifting component, and a clamping component. The lifting component is slidably mounted on the transverse component via the moving plate 43. The clamping component is fixed to the lower end of the lifting component. The transverse component includes a crossbeam 41 and a guide rail C42 fixed on the crossbeam 41. The moving plate 43 is provided with a slider that cooperates with the guide rail C42. The moving plate 43 is also provided with a drive motor 47. The crossbeam 41 is provided with a rack 46. The moving plate 43 moves on the crossbeam 41 through the meshing of the gear on the drive motor 47 and the rack 46. The transverse component can also be driven by a linear motor or an electric cylinder.

[0092] The lifting assembly includes a connecting column C44 slidably mounted on the moving plate 43 and a lifting cylinder C45 fixed on the moving plate 43 and driving the connecting column C44 to rise and fall. To improve production efficiency, there are three clamping assemblies, which are fixed by a connecting beam 49. The lifting cylinder C45 is fixed to the connecting beam 49, driving the three clamping assemblies to rise and fall simultaneously. When the lifting assembly moves laterally, it moves the batteries from the loading station, end cutting station, and middle cutting station to the next station in sequence. Specifically, it moves the batteries from the loading station to the end cutting station, from the end cutting station to the middle cutting station, and from the middle cutting station to the unloading station. This transfer mechanism 4 allows batteries from multiple stations to be transferred synchronously, simplifies the control logic, and further improves efficiency. To ensure the stable operation of the transfer mechanism 4, preferably, there are two sliding mounting plates, each equipped with a lifting assembly. The lower ends of both lifting assemblies are fixed to the connecting beam 49.

[0093] The gripping assembly 48 includes a gripping frame, cylinders, and clamping plates. The gripping frame has a U-shaped frame structure, and a top connecting plate is fixed to the top of the gripping frame. The top connecting plate is fixed to the bottom of the connecting column C44. Two sets of cylinders are fixed to both sides of the gripping frame. The piston rod of the cylinder passes through the side wall of the gripping frame and is fixed to the clamping plate. The cylinders drive the clamping plates on both sides to move closer together to clamp the battery 7. The dual cylinders drive the clamping plates synchronously, resulting in a more balanced clamping force, avoiding damage to the battery casing from unilateral compression, and the direct drive of the clamping plates by the cylinders results in a faster response speed.

[0094] The gripping frame is divided into two frames by a central partition. Each frame has clamping plates on two opposite sides. A central partition is located on the side of the clamping plate closest to battery 7, and end partitions are located at both ends. These partitions enable synchronous transfer of multiple batteries. The central and end partitions work together to form independent locking positions, ensuring accurate positioning and allowing for the gripping of two batteries at a time, thus increasing production capacity. Furthermore, to ensure stable movement of the clamping plates, the gripping frame is equipped with a guide sleeve. Guide posts are fixed to the clamping plates and inserted into the guide sleeve.
