Description

Technical Field

[0001] This invention relates to the field of battery cell electrode processing technology, specifically to a multi-set battery cell electrode flipping and balancing gantry hoisting device. Background Technology

[0002] During battery manufacturing, testing, or maintenance, it is crucial to check the positive and negative polarities of the battery and, if necessary, flip it to ensure that the positive and negative terminals are connected correctly. Incorrect polarity can lead to damage to the battery module, performance degradation, or even safety accidents.

[0003] Prior art 1 (Chinese patent CN112331870B, published on 2025-02-18) discloses a cell flipping mechanism for lithium battery production, comprising a flipping mechanism and a pushing mechanism disposed on the side of the flipping mechanism for pushing the cell. The flipping mechanism includes a spring-loaded roller assembly for clamping the cell, a pressing cylinder assembly for driving the spring-loaded roller assembly to clamp the cell, and a flipping drive cylinder for driving the spring-loaded roller assembly to flip. The pushing mechanism includes a primary pushing cylinder, a secondary pushing cylinder, and a pushing cylinder. This invention, with its 180° flipping mechanism, solves the problem of cell tabs collapsing due to gravity during the first rotation of the cell separator, thus improving cell yield. Simultaneously, the flipping platform adopts an automatic spring-loaded low-resistance roller structure design, which prevents friction and scratches on the cell surface as it passes over the flipping platform.

[0004] There is also a prior art (Chinese patent CN218114142U, published on 2022-12-23) for a cell processing flipping mechanism, including a mounting bracket, a screw-driven slide table mounted on the mounting bracket, a drive slider mounted on the screw-driven slide table, a mounting platform mounted on the drive slider, an electric guide rail rotatably mounted between the inner walls of both sides of the mounting platform via a rotating shaft, a synchronous belt drive assembly mounted on the mounting platform, the synchronous belt drive assembly connected to the rotating shaft, and two electric grippers mounted on the side of the two gripper mounting plates that are close to each other. These grippers are rotated via the output end of a servo motor, thereby driving the second turntable to rotate, which in turn drives the rotating shaft to rotate, which in turn drives the electric guide rail to rotate, thereby driving the gripper mounting plates to flip, thus rotating the cell. This allows both cells to flip simultaneously for subsequent cell pairing.

[0005] While existing technologies can flip battery cells, they cannot further limit the position of the cells during the flipping process. During the flipping process, the cells are prone to displacement due to inertia or external forces, resulting in inaccurate cell positions after flipping, which affects subsequent assembly or testing processes.

[0006] Therefore, we propose a multi-group cell pole flipping and balancing gantry hoisting device to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-cell electrode rotation and balancing gantry hoisting device to solve the problem mentioned in the background art that the current market cannot further limit the position of the cells when rotating them, and the cells are prone to displacement due to inertia or external force during the rotation process, resulting in inaccurate cell positions after rotation, which affects subsequent assembly or testing processes.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a multi-set battery cell terminal column flipping and balancing gantry hoisting device, comprising a hoist and battery cell assemblies to be hoisted and flipped. A fixed frame is fixedly connected to one side of the lower part of the hoist, and a movable frame is fixedly connected to the other side of the lower part of the hoist. Clamping plates for holding the battery cell assemblies are provided on the inner sides of both the fixed frame and the movable frame. A connecting rod for enhancing clamping stability is fixedly connected to the inner side of the clamping plate. An adsorption mechanism is also provided on the clamping plate on the inner side of the movable frame. A suction cup is provided on the inner side of the clamping plate. The adsorption mechanism achieves negative pressure suction treatment on the inner side of the suction cup through the movement of its included abutment rod, improving the stability of the battery cell assembly's positioning. An abutment mechanism is provided on the side of the clamping plate. The abutment mechanism drives the rotating pressure plate included therein to rotate through the suction action of the adsorption mechanism, further clamping and limiting the battery cell assembly.

[0009] Preferably, a fixed steel plate with an outward protrusion is fixedly connected to the side of the battery cell assembly, and a groove corresponding to the position and shape of the fixed steel plate is provided on the inner side of the clamping plate. A cylinder is fixedly connected to the hanger, and the output end of the cylinder is fixedly connected to the moving frame. A docking rod is fixedly connected to the inner side of the clamping plate, and docking holes corresponding to the positions of the docking rods are opened on the fixed steel plate. The docking holes and the docking rods cooperate with each other to limit the position of the battery cell assembly.

[0010] Preferably, a flip motor is fixedly connected to the outer side of the movable frame, and the output end of the flip motor is fixedly connected to the clamping plate. A sensor frame is fixedly connected to the outer side of the clamping plate, and a sensor rod is slidably connected inside the sensor frame. The sensor rod is slidably connected to the clamping plate, and the sensor frame provides real-time feedback on the clamping status of the clamping plate through the position movement of the sensor rod.

[0011] Preferably, the adsorption mechanism includes a fixed cylinder, which is disposed through the clamping plate and is fixedly connected to the suction cup on the inner side. A through hole is provided between the fixed cylinder and the suction cup, and a movable plate is slidably connected inside the fixed cylinder.

[0012] Preferably, the abutment rod is slidably connected to the clamping plate and is located between two sets of fixed cylinders. The outer end of the abutment rod is fixedly connected to a connecting plate, and the abutment rod slides along the clamping plate by abutting against the battery cell assembly.

[0013] Preferably, a connecting rod is fixedly connected to the movable plate, and the connecting rod is slidably connected to the outside of the fixed cylinder, and the outer end of the connecting rod is fixedly connected to the inner side of the connecting plate.

[0014] Preferably, the abutment mechanism includes a positioning shaft, which is fixedly connected to the side of the clamping plate. The positioning shaft is symmetrically distributed about the center point of the clamping plate. A rotating pressure plate is rotatably connected to the outer side of the positioning shaft, and the inner end of the rotating pressure plate has a zigzag structure. The zigzag end of the rotating pressure plate is made of rubber.

[0015] Preferably, an inflatable airbag is fixedly connected to the outer side of the clamping plate, and a connecting pipe is provided between the inflatable airbag and the outer side of the fixed cylinder, and a linkage plate is fixedly connected to the outer side of the inflatable airbag.

[0016] Preferably, the outer side of the rotating pressure plate is provided with a sliding groove, and a sliding rod is slidably connected inside the sliding groove, and the end of the sliding rod is fixedly connected to the side of the linkage plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) A movable frame is provided. After the battery cell assembly is placed, the cylinder is started. The movable frame can be moved by the cylinder. At this time, the movable frame can move the clamping plate set on its inner side to the side of the battery cell assembly. When the clamping plate moves to contact the battery cell assembly, the docking rod will be inserted into the docking hole on the fixed steel plate to achieve preliminary positioning and limit. The two sets of docking rods and docking holes cooperate with each other to further improve the stability of the battery cell assembly clamping. This ensures that when the flipping motor drives the battery cell assembly to perform subsequent flipping operations, the battery cell assembly will not shift or fall off, thus ensuring the smoothness and safety of the flipping process.

[0018] (2) As the moving frame gradually approaches the battery cell assembly, the side of the battery cell assembly will come into contact with the sensing rod. As the moving frame continues to move, the sensing rod will move along the sensing frame under the limiting action of the battery cell assembly. The displacement data of the sensing rod can be obtained in real time through the sensing element set on the sensing frame, and the data is transmitted to the control system for calculation and analysis to ensure that the moving frame moves into place and further ensure the stability of the battery cell assembly clamping.

[0019] (3) When the clamping plate clamps the battery cell assembly, the fixing steel plate on the outside of the battery cell assembly will engage with the groove on the inside of the clamping plate, thereby further preventing the battery cell assembly from falling off during subsequent flipping. At the same time, a suction cup is also provided on the inside of the clamping plate. During the clamping process, the battery cell assembly will squeeze the suction cup, and the suction cup will adsorb the battery cell assembly, improving the stability of the battery cell assembly during the clamping process, preventing it from shifting due to shaking during transportation or flipping, and also reducing the risk of damage caused by the battery cell assembly falling off during processing.

[0020] (4) When the clamping plate comes into contact with the battery cell assembly, the battery cell assembly will abut against the abutment rod, causing the abutment rod to slide along the clamping plate. When the abutment rod slides, it will drive the connecting plate to move, thereby causing the connecting plate to drive the moving plate to slide in the fixed cylinder through the connecting rod. Since there is a through hole between the fixed cylinder and the suction cup, the sliding of the moving plate will cause a negative pressure to be formed on the inside of the suction cup. This negative pressure is transmitted to the inside of the suction cup through the through hole, realizing the tight adsorption between the suction cup and the surface of the battery cell assembly, thereby adsorbing the battery cell assembly on the suction cup and further improving the positioning stability.

[0021] (5) The sliding of the moving plate will cause the air pressure inside the fixed cylinder to change. The gas enters the expansion airbag through the connecting pipe, causing the expansion airbag to expand. The expansion airbag will push the linkage plate to move. The linkage plate slides in the sliding groove on the outside of the rotating pressure plate through the sliding rod, thereby driving the rotating pressure plate to rotate around the positioning shaft. The tortuous rubber structure on the inner end of the rotating pressure plate will further press the battery cell assembly, limiting and fixing the battery cell assembly from multiple directions, which greatly improves the stability of the battery cell assembly during the flipping process, avoids shaking or displacement, and effectively improves the quality and safety of the entire hoisting and flipping operation.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1: To initially achieve the positioning and limiting of the battery cell assembly 5, and to prevent displacement or detachment when the flipping motor 6 drives the battery cell assembly 5 to flip, such as... Figures 1-4 and Figure 6 The present invention provides the following technical solution: a multi-group battery cell pole flipping and balancing gantry hoisting device, comprising: a hoist 1 and a battery cell assembly 5 to be lifted and flipped; a fixed frame 2 is fixedly connected to one side of the lower part of the hoist 1, and a movable frame 3 is fixedly connected to the other side of the lower part of the hoist 1; clamping plates 7 for holding the battery cell assembly 5 are provided on the inner sides of both the fixed frame 2 and the movable frame 3; a protruding fixed steel plate 10 is fixedly connected to the side of the battery cell assembly 5; a groove corresponding to the position and shape of the fixed steel plate 10 is provided on the inner side of the clamping plate 7; a cylinder 4 is fixedly connected to the hoist 1, and the output end of the cylinder 4 is connected to the movable frame. The three components are fixedly connected. A docking rod 9 is fixedly connected to the inner side of the clamping plate 7. A docking hole 8 corresponding to the position of the docking rod 9 is opened on the fixed steel plate 10. The docking hole 8 and the docking rod 9 cooperate to dock and limit the position of the battery cell assembly 5. A flip motor 6 is fixedly connected to the outer side of the moving frame 3, and the output end of the flip motor 6 is fixedly connected to the clamping plate 7. A sensor frame 11 is fixedly connected to the outer side of the clamping plate 7. A sensor rod 12 is slidably connected inside the sensor frame 11 and slidably connected to the clamping plate 7. The sensor frame 11 provides real-time feedback on the clamping status of the clamping plate 7 by moving the position of the sensor rod 12.

[0026] In the battery cell processing equipment, a movable frame 3 is provided. After the battery cell assembly 5 is accurately placed in the predetermined position, the operator starts the cylinder 4. Under the pushing action of the cylinder 4, the movable frame 3 moves smoothly along the pre-set track or direction. As the movable frame 3 moves, the clamping plate 7 set on its inner side begins to move closer to the battery cell assembly 5. When the clamping plate 7 gradually moves to close contact with the battery cell assembly 5, the docking rod 9 set on the clamping plate 7 will be inserted into the corresponding docking hole 8 on the fixed steel plate 10. The cooperation between the docking rod 9 and the docking hole 8 realizes the initial positioning and limit, which further greatly improves the stability of clamping the battery cell assembly 5 and lays the foundation for the subsequent flipping operation. It ensures that when the flipping motor 6 drives the battery cell assembly 5 to flip, the battery cell assembly 5 can be firmly fixed in the original position and will not shift or fall off, thus ensuring the stability and safety of the flipping process in all aspects.

[0027] As the moving frame 3 gradually approaches the battery cell assembly 5, the side of the battery cell assembly 5 will come into contact with the sensing rod 12. As the moving frame 3 continues to move, the sensing rod 12 will slide along the sensing frame 11 under the limiting action of the battery cell assembly 5. Through calculation and analysis, the control system can accurately determine whether the moving frame 3 has moved into place, thereby further ensuring the stability and reliability of clamping the battery cell assembly 5 and providing a solid guarantee for subsequent processing operations.

[0028] Example 2: To effectively prevent the risk of damage caused by the cell assembly 5 falling off during processing due to displacement caused by shaking, and to further ensure the smooth progress of processing and product quality, such as... Figure 5 and Figures 7-9 The present invention provides the following technical solution: a multi-group battery cell pole flipping and balancing gantry hoisting device, wherein a connecting rod 9 for enhancing clamping stability is fixedly connected to the inner side of the clamping plate 7, and an adsorption mechanism is also provided on the clamping plate 7 inside the moving frame 3. A suction cup 13 is provided on the inner side of the clamping plate 7. The adsorption mechanism achieves negative pressure suction treatment on the inner side of the suction cup 13 through the movement of the abutment rod 16 included therein, thereby improving the stability of limiting the battery cell assembly 5. The adsorption mechanism includes a fixed cylinder 15, which is disposed through the clamping plate 7, and the fixed cylinder 15 is... The inner side of the fixed cylinder 15 is fixedly connected to the suction cup 13. A through hole is provided between the fixed cylinder 15 and the suction cup 13. The moving plate 17 is slidably connected inside the fixed cylinder 15. The abutment rod 16 is slidably connected to the clamping plate 7 and is located between the two sets of fixed cylinders 15. The outer end of the abutment rod 16 is fixedly connected to the connecting plate 14. The abutment rod 16 slides along the clamping plate 7 through the abutment action with the battery cell assembly 5. The moving plate 17 is fixedly connected to the connecting rod 20, and the connecting rod 20 is slidably connected to the outer side of the fixed cylinder 15. The outer end of the connecting rod 20 is fixedly connected to the inner side of the connecting plate 14.

[0029] When the clamping plate 7 clamps the battery cell assembly 5, firstly, during the clamping process, the fixing steel plate 10 tightly engages with the groove on the inner side of the clamping plate 7. The edge contour of the fixing steel plate 10 matches the shape of the groove on the inner side of the clamping plate 7, forming a stable connection structure, which greatly enhances the bonding force between the battery cell assembly 5 and the clamping plate 7, thereby effectively preventing the battery cell assembly 5 from falling off during subsequent flipping operations. At the same time, a suction cup 13 is also provided on the inner side of the clamping plate 7. As the clamping plate 7 gradually approaches and clamps the battery cell assembly 5, the surface of the battery cell assembly 5 will contact the suction cup 13 and be squeezed. When squeezed by the battery cell assembly 5, the suction cup 13 will deform to a certain extent, thereby generating an adsorption force on the battery cell assembly 5, which greatly improves the stability of the battery cell assembly 5 during the clamping process. When the clamping plate 7 contacts the battery cell assembly 5, the battery cell assembly 5 will abut against the abutment rod 16 provided on the clamping plate 7. Under the action of pressure, the abutment rod 16... The 6 will slide along the clamping plate 7. During the sliding process, the contact rod 16 will drive the connected plate 14 to move together. The connected plate 14 is connected to the moving plate 17 through the connecting rod 20. When the connected plate 14 moves, it will drive the moving plate 17 to slide inside the fixed cylinder 15. Since there is a through hole between the fixed cylinder 15 and the suction cup 13, when the moving plate 17 slides inside the fixed cylinder 15, it will change the air pressure inside the fixed cylinder 15. Through the sliding of the moving plate 17, some of the air inside the fixed cylinder 15 will be discharged through the through hole, thereby forming a negative pressure environment inside the suction cup 13. The negative pressure is quickly transmitted to the inside of the suction cup 13 through the through hole, so that the air between the suction cup 13 and the surface of the battery cell assembly 5 is further extracted, realizing the tight adsorption between the suction cup 13 and the surface of the battery cell assembly 5, enhancing the adsorption firmness, improving the limiting stability of the battery cell assembly 5 during the clamping process, ensuring that the battery cell assembly 5 always maintains a stable position throughout the entire processing process, and providing a strong guarantee for high-quality processing.

[0030] Example 3: To effectively improve the quality of the entire hoisting and flipping operation, ensure that the battery cell assembly 5 can accurately complete the flipping action, further enhance the safety of the operation, and avoid safety accidents caused by the battery cell assembly 5 falling off or shifting, such as... Figure 4 and Figures 7-9The present invention provides the following technical solution: a multi-group battery cell electrode column flipping and balancing gantry hoisting device, wherein the clamping plate 7 is provided with an abutment mechanism on its side. The abutment mechanism drives the rotating pressure plate 24 contained therein to rotate through the suction action of the adsorption mechanism, further clamping and limiting the battery cell assembly 5. The abutment mechanism includes a positioning shaft 25, which is fixedly connected to the side of the clamping plate 7. The positioning shafts 25 are symmetrically distributed about the center point of the clamping plate 7. A rotating mechanism is rotatably connected to the outer side of the positioning shafts 25. The rotating pressure plate 24 has a zigzag structure on its inner end, and the zigzag end of the rotating pressure plate 24 is made of rubber. An inflatable airbag 19 is fixedly connected to the outer side of the clamping plate 7. A connecting pipe 18 is connected between the inflatable airbag 19 and the outer side of the fixed cylinder 15. A linkage plate 23 is fixedly connected to the outer side of the inflatable airbag 19. A sliding groove 21 is provided on the outer side of the rotating pressure plate 24. A sliding rod 22 is slidably connected inside the sliding groove 21. The end of the sliding rod 22 is fixedly connected to the side of the linkage plate 23.

[0031] As the position of the movable plate 17 changes, the connecting pipe 18 guides the gas in the fixed cylinder 15 into the expansion bladder 19. When the gas rushes into the expansion bladder 19 through the connecting pipe 18, the volume of the expansion bladder 19 gradually increases, and the internal pressure also increases. The expansion bladder 19 pushes the linkage plate 23 outward. Under the action of the thrust, the linkage plate 23 begins to move, thereby driving the slide rod 22 to slide in the slide groove 21, so that the rotating pressure plate 24 begins to rotate around the positioning shaft 25. When the rotating pressure plate 24 rotates to the appropriate position, the tortuous rubber structure on its inner end side can contact the battery cell assembly 5, increasing the contact area with the surface of the battery cell assembly 5 and improving the stability of the pressing.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
