Description

Technical Field

[0001] This invention relates to the field of battery processing technology, specifically to a battery longitudinal stacking and bundling system. Background Technology

[0002] With the rapid development of industries such as new energy vehicles and electrochemical energy storage, the demand for battery cells such as lithium-ion batteries and sodium-ion batteries is increasing day by day, and their production scale is constantly expanding. This has put forward higher requirements for production efficiency and cost control. In the process of assembling battery modules, integrating multiple individual battery cells into a stable battery stack is a key process.

[0003] Existing battery stacking and bundling systems typically have multiple workstations. After multiple batteries are stacked and compressed longitudinally, the compressed batteries are transferred to the bundling station by switching between workstations. The stacked and compressed batteries are then manually fitted with steel straps. However, it is not convenient to continue compressing the batteries when transferring them at the stacking and compression station. As a result, due to the elasticity of the batteries themselves (especially pouch or square aluminum-cased cells), if the compression force is released before transferring them to the bundling station, the compressed cells may spring back, causing changes in the stack size and thus affecting the bundling effect.

[0004] Therefore, we propose a battery longitudinal stacking and bundling system to address the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a battery longitudinal stacking and bundling system to solve the problem mentioned in the background art that, when batteries are being pressed and transferred at the stacking and pressing station, it is not convenient to continue pressing the batteries. As a result, during the transfer process, because the batteries themselves have a certain degree of elasticity, if the pressing force is released before the transfer to the bundling station, the already compressed battery cells may spring back.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a battery longitudinal stacking and bundling system, comprising a workbench and an adjustment base plate installed in the middle of the workbench, a driving structure installed below the adjustment base plate, and a first station, a second station, a third station and a fourth station arranged sequentially in the circumferential direction of the adjustment base plate, the adjustment base plate being used to rotate and switch between multiple stations, a support frame being fixed on the workbench, and a clamping cylinder being installed on the support frame, a stacking pressure plate being installed on the telescopic end of the clamping cylinder, the stacking pressure plate being used to clamp the longitudinally stacked batteries, and a clamping component being installed on the first station, the second station, the third station and the fourth station, the clamping component being used to clamp the batteries to be transferred after stacking and clamping, to prevent the batteries from springing back after stacking and clamping.

[0007] Preferably, the drive structure includes a linkage gear ring fixed to the bottom of the adjustment base plate, and the side of the linkage gear ring is meshed with a drive gear, which is mounted on the output shaft of the servo motor, and the adjustment base plate can rotate on the worktable.

[0008] By adopting the above technical solution, the rotation of the active gear enables the meshing linkage gear ring to drive the adjustment plate to rotate synchronously, thereby switching between multiple workstations.

[0009] Preferably, the bottom of the first, second, third and fourth workstations are all equipped with a centering adjustment component. The centering adjustment component includes a support plate fixed on the adjustment base plate. A double-headed cylinder is fixed inside the support plate, and a centering block is installed on the telescopic end of the double-headed cylinder.

[0010] By adopting the above technical solution, the opening of the double-headed cylinder enables the centering blocks on both sides to move synchronously relative to each other, thereby centering the battery placed on the support plate by the movement of the centering blocks.

[0011] Preferably, the clamping component includes a limiting frame fixed on the adjusting base plate, and a first cylinder is installed in the middle of the limiting frame. A movable back plate is installed on the telescopic end of the first cylinder, and a second cylinder is installed on the side of the limiting frame. A lateral clamping plate is installed on the telescopic end of the second cylinder. A blocking block is installed on the end of the lateral clamping plate away from the limiting frame. A first limiting plate is connected to the side of the lateral clamping plate facing the battery through a first spring, and a movable guide post is fixedly connected to the first limiting plate. The movable guide post is installed through the middle of the central stop block, and the central stop block is installed on the lateral clamping plate. The central stop block is connected to the lateral clamping plate through a second spring. A transmission gear is provided on the inner side of the movable guide post, and a vertical screw is keyed to the middle of the transmission gear. A second limiting plate perpendicular to the lateral clamping plate is connected to the upper end of the vertical screw. A guide pressure block is provided on the side of the movable guide post and fixed to the side of the lateral clamping plate away from the battery.

[0012] By adopting the above technical solution, the opening of the second cylinder can push the side clamping plate to move towards the battery, thereby clamping the battery.

[0013] Preferably, the cross-section of the combination of the lateral clamping plate and the blocking block is set as an "L" shape, and the lateral clamping plate and the blocking block are symmetrically arranged about the central axis of the limiting frame.

[0014] By adopting the above technical solution, the blocking block can be set to conveniently block the front side of the battery when limiting its position.

[0015] Preferably, the movable guide post on the first limiting plate can slide horizontally on the central stop, and the central stop can slide vertically along the side plate.

[0016] By adopting the above technical solution, the movement of the central stop along the vertical direction of the lateral plate can drive the first limiting plate to move downward synchronously. The downward movement of the first limiting plate can then partially offset the rebound force of the battery.

[0017] Preferably, a toothed block is provided on the inner side of the middle part of the movable guide post, and the toothed block on the inner side of the middle part of the movable guide post is meshed with the transmission gear. The upper end of the vertical screw in the middle of the transmission gear is threadedly connected to the second limiting plate, and the second limiting plate can slide along the vertical direction of the lateral clamping plate.

[0018] By adopting the above technical solution, the movement of the guide post can cause the transmission gear to drive the vertical screw to rotate. The rotation of the vertical screw can cause the threaded side clamp to move downward, thereby generating a vertical downward pressure on the battery.

[0019] Preferably, the guide block includes a straight portion and an inclined portion on the side near the movable guide post.

[0020] Preferably, the outer surface contour of the end of the movable guide post away from the first limiting plate is set to an arc shape, and the arc-shaped end of the movable guide post is in contact with the straight part on the guide block in the initial state.

[0021] By adopting the above technical solution, when the arc-shaped end of the movable guide post contacts the straight part, the movable guide post will not move. When the movable guide post moves and contacts the inclined part, the inclined part can squeeze the movable guide post.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the battery longitudinal stacking and bundling system can perform multi-directional compression on the battery at the battery placement station, preventing the battery from releasing the compression force during the compression and transfer process at the stacking and compression station, which would cause the compressed battery cell to spring back.

[0023] 1. After the first limiting plate is pressed against the battery, it can drive the moving guide column to move synchronously. The movement of the moving guide column can cause the transmission gear to drive the vertical screw to rotate. The rotation of the vertical screw will drive the second limiting plate to move downward, providing downward pressure on the stacked and pressed battery. After the moving guide column continues to move and contacts the inclined part, the inclined part can press the moving guide column, so that the moving guide column and the first limiting plate can also move downward, thereby also providing downward pressure on the battery. This prevents the stacked and pressed battery from springing back during transfer, which would affect the manual steel strapping in the next process.

[0024] 2. The centering block can be moved synchronously by the dual-head cylinder. The movement of the centering block can push the battery on the support plate so that the battery can be placed in the center, and avoid the force of the subsequent stacking plate moving down will not be centered on the battery.

[0035] 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.

[0036] Example 1: Please refer to Figures 1-9Existing battery stacking and bundling systems typically employ multiple workstations. After longitudinally stacking and compressing multiple batteries, the compressed batteries are transferred to the bundling station via workstation switching. The stacked and compressed batteries are then manually fitted with steel straps. However, during the transfer process at the stacking and compression station, it is inconvenient to continue compressing the batteries. Because the batteries themselves (especially pouch or square aluminum-cased cells) have a certain degree of elasticity, if the compression force is released before transferring to the bundling station, the already compressed cells may spring back, causing changes in the stack dimensions and affecting the bundling effect. To solve this technical problem, this embodiment discloses the following technical content: a battery longitudinal stacking and bundling system... The stacking and bundling system includes a workbench 1 and an adjustment base plate 2 installed in the middle of the workbench 1. A drive structure is installed below the adjustment base plate 2. The adjustment base plate 2 has a first station 5, a second station 6, a third station 7, and a fourth station 8 arranged sequentially in the circumferential direction. The adjustment base plate 2 is used to rotate and switch between multiple stations. A support frame 9 is fixed on the workbench 1, and a clamping cylinder 10 is installed on the support frame 9. A stacking pressure plate 11 is installed on the telescopic end of the clamping cylinder 10. The stacking pressure plate 11 is used to clamp the vertically stacked batteries. A clamping component is installed on the first station 5, the second station 6, the third station 7, and the fourth station 8. The clamping component is used to clamp the batteries to be transferred after stacking and clamping to prevent the batteries from springing back after stacking and clamping. The driving structure includes a linkage gear ring 3 fixed to the bottom of the adjustment base plate 2, and a drive gear 4 meshing with the side of the linkage gear ring 3. The drive gear 4 is mounted on the output shaft of the servo motor, allowing the adjustment base plate 2 to rotate on the worktable 1. The clamping component includes a limiting frame 12 fixed to the adjustment base plate 2, and a first cylinder 13 is mounted in the middle of the limiting frame 12. A movable back plate 14 is mounted on the telescopic end of the first cylinder 13, and a second cylinder 15 is mounted on the side of the limiting frame 12. A lateral clamping plate 16 is mounted on the telescopic end of the second cylinder 15, and a blocking block 17 is mounted on the end of the lateral clamping plate 16 away from the limiting frame 12. The side of the lateral clamping plate 16 facing the battery is connected to a first limiting plate 21 via a first spring 24, and the first limiting plate 21... A movable guide post 22 is fixedly connected to the upper part of the central stop 23, which is mounted through the middle of the central stop 23. The central stop 23 is mounted on the side plate 16 and is connected to the side plate 16 by a second spring 25. A transmission gear 26 is provided on the inner side of the movable guide post 22, and a vertical screw 27 is keyed to the middle of the transmission gear 26. A second limiting plate 28, which is perpendicular to the side plate 16, is connected to the upper end of the vertical screw 27. A guide block 29, which is fixed to the side of the side plate 16 away from the battery, is provided on the side of the movable guide post 22. The cross-section of the side plate 16 and the blocking block 17 after combination is set as an "L" shape, and the side plate 16 and the blocking block 17 are symmetrically arranged about the central axis of the limiting frame 12.The movable guide post 22 on the first limiting plate 21 can slide horizontally on the central stop 23, and the central stop 23 can slide vertically along the lateral clamping plate 16. A toothed block is provided on the inner side of the middle portion of the movable guide post 22, and this toothed block is meshed with the transmission gear 26. The upper end of the vertical screw 27 in the middle of the transmission gear 26 is threadedly connected to the second limiting plate 28. The second limiting plate 28 can slide vertically along the lateral clamping plate 16. The guide block 29 near the movable guide post 22 includes a straight portion 291 and an inclined portion 292. The outer surface contour of the end of the movable guide post 22 away from the first limiting plate 21 is arc-shaped, and the arc-shaped end of the movable guide post 22 initially contacts the straight portion 291 on the guide block 29. A ball bearing can be installed on the side of the second limiting plate 28 that contacts the battery to reduce the friction between the second limiting plate 28 and the battery.

[0037] When batteries need to be stacked and bundled, the workers first stack the batteries vertically in sequence at the first station 5. After stacking the batteries, the servo motor is turned on, which causes the drive gear 4 to rotate. The rotation of the drive gear 4 causes the meshing linkage ring 3 to drive the adjustment base plate 2 to rotate synchronously, thereby rotating the first station 5 to the second station 6. Then, the clamping cylinder 10 is turned on, which causes the stacking plate 11 to move downward, thereby pressing the stacked batteries. After the batteries are pressed, the rotation of the drive gear 4 causes the linkage ring 3 to drive the adjustment base plate 2 to rotate, rotating the first station 5 to the third station 7. At the third station 7, the workers bundle the stacked and pressed batteries with steel straps. After the batteries are bundled, the linkage ring 3 continues to drive the adjustment base plate 2 to rotate, rotating the first station 5 to the fourth station 8. The bundled batteries are then removed by an external robotic arm. This cycle is repeated to complete the vertical stacking and bundling of the batteries.

[0038] To avoid the problem of springing back during transfer after the batteries are stacked and compressed, the following solution is disclosed in this embodiment, the details of which are as follows:

[0039] Opening the first cylinder 13 allows the movable back plate 14 to move and contact the battery. Opening the second cylinder 15 allows the lateral clamping plate 16 to move towards the side of the battery. The movement of the lateral clamping plate 16 causes the first limiting plate 21 to move towards the battery. After the first limiting plate 21 contacts and presses against the battery, it drives the moving guide post 22 to move on the central stop block 23. At this time, the arc-shaped end of the moving guide post 22 contacts the straight section 291 on the guide pressure block 29. After the moving guide post 22 moves, the toothed block on its inner side causes the meshing transmission gear 26 to rotate. The rotation of the transmission gear 26 drives the vertical screw 27 to rotate. The rotation of the vertical screw 27 causes the threaded second limiting plate 28 to move downwards and press against the battery, providing vertical support for the battery. With downward pressure, as the lateral clamping plate 16 continues to move, the second limiting plate 28, with its bottom ball bearings, can move normally in the horizontal direction. After the lateral clamping plate 16 continues to move, the toothed block on the inner side of the middle of the moving guide post 22 on the side of the first limiting plate 21 disengages from the transmission gear 26. Then, after moving, the arc-shaped end of the moving guide post 22 contacts the inclined portion 292 on the guide pressure block 29. The inclined portion 292 can squeeze the moving guide post 22, causing it and the first limiting plate 21 to move downward synchronously. After the moving guide post 22 moves, the center stop 23 can also move on the lateral clamping plate 16. The downward movement of the first limiting plate 21 can also provide downward pressure on the battery, thereby preventing the battery from springing back when it is transferred after being stacked and pressed.

[0040] Example 2: The technical content disclosed in this example is a further improvement based on Example 1 described above, such as... Figure 3 and Figure 5 As shown, the following technical content is disclosed in this embodiment: the bottom of the first station 5, the second station 6, the third station 7 and the fourth station 8 are all equipped with a centering adjustment component. The centering adjustment component includes a support plate 18 fixed on the adjustment base plate 2. A double-headed cylinder 19 is fixed inside the support plate 18, and a centering block 20 is installed on the telescopic end of the double-headed cylinder 19.

[0041] The batteries are manually placed on the support plate 18 for stacking. After the bottom battery is placed, the opening of the double-headed cylinder 19 causes the centering blocks 20 at the two telescopic ends to move towards the center of the support plate 18. The synchronous movement of the support plate 18 pushes the battery so that it can be placed in the center on the support plate 18, so that the stacked batteries can be pressed together later.

[0042] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] 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.
