[0022] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] Embodiment 1

[0024] See also Figures 1 to 5 , a pole piece reel swing transfer device, which can swing and transfer the pole piece reel to an angle and distance to realize the swing transfer of the pole piece reel. The pole piece reel swing transfer device includes a fixing mechanism 1, a swing mechanism 2, a material taking mechanism 3 and a swing drive mechanism 4. The fixing mechanism 1 is the overall installation and fixing structure of the pole piece reel swing transfer device. The swing mechanism 2 and the swing drive mechanism 4 are installed through the fixing mechanism 1, and the swing drive mechanism 4 drives the swing mechanism 2 to swing on the fixing mechanism 1; the material taking mechanism 3 is installed on the swing mechanism 2 and swings with the swing mechanism 2. Thus, an integral pole piece reel swing transfer device is formed, and the pole piece reel swing transfer device can be fixed at the position where the pole piece reel swing transfer device is used through the fixing mechanism 1. The fixing mechanism 1 can be set to a commonly used external structure such as a plate structure, a rod structure, etc. The swing mechanism 2 is a component that realizes the pole piece reel swing transfer device to transfer the pole piece reel to a certain angle and distance. The swing mechanism 2 can be set to a plate structure or a rod structure. The material taking mechanism 3 is a structure for taking and placing the electrode roll. Through the material taking mechanism 3, the electrode roll can be taken out and fixed before the electrode roll is transferred, and the electrode roll can be put down after the electrode roll is transferred to the set position. The swing mechanism 2 is set on the fixed mechanism 1 through the swing of the rotating shaft, and the swing drive mechanism 4 drives the swing mechanism 2 to swing on the fixed mechanism 1. The material taking mechanism 3 is set at one end of the swing mechanism 2. The material taking mechanism 3 swings with the swing mechanism 2, so that the swing drive mechanism 4 can drive the material taking mechanism 3 to move a certain angle and distance, so as to realize the transfer of the electrode roll to a certain angle and distance. The swing drive mechanism 4 can adopt a telescopic cylinder. The pole piece reel swing transfer device drives the swing mechanism 2 to swing on the fixed mechanism 1 through the swing drive mechanism 4 to drive the material taking mechanism 3 to move a certain angle and distance, so that the pole piece reel can be quickly transferred with high production efficiency; and the pole piece reel swing transfer device has a simple structure and a small size, which can solve the technical problem that the pole piece reel is located in a small space in a large equipment and is difficult to load and unload manually or with general loading and unloading equipment. Therefore, the pole piece reel can be recycled in battery production, the cost of the battery can be reduced, and the market competitiveness of the battery can be improved.

[0025] See also Figures 1 to 4The material picking mechanism 3 can adopt the following structure: it includes a material picking barrel 31, a support block 32 and a support block driving assembly 33. The material picking barrel 31 is a hollow cylindrical structure. The support block 32 is movably arranged in the material picking barrel 31. The support block driving assembly 33 drives the support block 32 to move radially on the material picking barrel 31. Therefore, when the material taking mechanism 3 is used to take the electrode sheet reel, the material taking cylinder 31 can be inserted into the inner side of the electrode sheet reel, and then the support block driving assembly 33 drives the support block 32 to move radially outward on the material taking cylinder 31, so that the support block 32 is pressed against the inner side of the electrode sheet reel, so that the material taking mechanism 3 is clamped and fixed on the inner side of the electrode sheet reel, and the electrode sheet reel is fixed, and then the electrode sheet reel can be further transferred; when the material taking mechanism 3 needs to put down the electrode sheet reel, the support block driving assembly 33 drives the support block 32 to move radially inward on the material taking cylinder 31, so that the support block 32 is released from the inner side of the electrode sheet reel, and then the electrode sheet reel can be taken down from the material taking mechanism 3. The material taking mechanism 3 clamps or loosens the electrode sheet reel by driving the support block 32 to move radially on the material taking cylinder 31 through the support block driving assembly 33, which makes it easy to take and put the electrode sheet reel, stably fix the electrode sheet reel, and has high production efficiency. In addition, it is best to set a circle of guard edge at the end of the material taking barrel 31 close to the swing mechanism 2 to block the pole piece reel to prevent the pole piece reel from touching the swing mechanism 2 and being damaged. The pole piece reel can also be positioned when the material taking barrel takes the pole piece reel.

[0026] See also Figure 3 and Figure 4 The material taking barrel 31 is provided with a radial mounting hole 311, and the support block 32 is movably arranged in the mounting hole 311; the support block driving assembly 33 drives the support block 32 to move radially in the mounting hole 311. In this way, the support block 32 can be radially mounted and moved on the material taking barrel 31; and the support block 32 is mounted through the mounting hole 311, so that the support block 32 is more stably and reliably mounted on the material taking barrel 31, so that the performance of the pole piece winding barrel swing transfer device is more reliable.

[0027] See also Figure 3 and Figure 4 The support block 32 is connected to the mounting hole 311 through a spring 321. In a natural state, the support block 32 is installed inside the mounting hole 311 through the spring 321. When the support block driving assembly 33 presses the support block 32, the support block 32 can be pushed out from the mounting hole 311. Therefore, when the support block 32 needs to be radially extended from the material taking barrel 31, the support block 32 can be pushed out by the support block driving assembly 33; when the support block 32 does not need to be radially extended from the material taking barrel 31, the support block 32 is automatically reset by the action of the spring 321. The use of this structure makes the material taking mechanism 3 simple in structure, and the reset of the support block 32 does not require power drive, which saves energy consumption of the winding barrel swing transfer device.

[0028] See also Figure 3 and Figure 5The support block 32 preferably adopts a cross-shaped structure, the mounting hole 311 is a through hole, the support block 32 radially penetrates the mounting hole 311, and the two sides of the support block 32 are connected in the mounting hole 311 by springs 321, so that the support block 32 and the material taking barrel 31 are more easily installed, and the support block driving assembly 33 is more likely to drive the support block 32 to move radially. A limiting plate 312 is arranged outside the mounting hole 311, and the limiting plate 312 is arranged at a position outside the support block 32 on the material taking barrel 31. The support block 32 is limited inside the mounting hole 311 by the limiting plate 312, and the top of the support block 32 passes through the mounting hole set on the limiting plate 312, thereby preventing the support block 32 from falling out of the mounting hole 311; specifically, two limiting plates 312 can be arranged, and the two limiting plates 312 are fixed at a position outside the support block 32 on the material taking barrel 31, and a mounting hole is arranged between the two limiting plates 312 for the support block 32 to pass through. The support block 32 is connected to the inner side of the limit plate 312 through a spring 321. A mounting groove 322 can be provided on the support block 32. One end of the spring 321 is installed in the mounting groove 322, and the other end of the spring 321 abuts against the inner side of the limit plate 312, so as to facilitate the installation of the spring 321 and the support block 32. The top of the support block 32 passes through the limit plate 312, and the bottom of the support block 32 passes through the mounting hole 311 to the inner side of the material taking barrel 31, so that the support block driving assembly 33 can press the support block 32 from the inner side of the material taking barrel 31 to drive the support block 32 to move radially on the material taking barrel 31. It is best to set an anti-slip structure on the top of the support block 32, so that the support block 32 is more reliable and stable when clamping the pole piece winding barrel.

[0029] See also Figure 3 and Figure 5 The mounting hole 311 is preferably set as a multi-step structure, and the limiting plate 312 is fixed on the outermost step structure of the mounting hole 311 by screws, so that the support block 32 can be limited by the limiting plate 312 and the mounting hole 311 in the space inside the mounting hole 311 when installed, and the bottom of the support block 32 passes through the inside of the material taking barrel 31. The support block 32 is provided with mounting grooves 322 on both sides, and the inner side of the limiting plate 312 is also provided with a mounting groove. One end of the spring 321 is installed in the mounting groove 322 of the support block 32, and the other end of the spring 321 is installed in the mounting groove inside the limiting plate 312. In this way, the support block 32 is stably installed in the space inside the mounting hole 311 by the spring 321, and the support block 32 can be driven to move radially on the material taking barrel 31 by the support block driving assembly 33 inside the material taking barrel 31.

[0030] See also Figures 1 to 5When the pole piece winding drum swing transfer device of this embodiment is used, the pole piece winding drum swing transfer device is fixed at the position where the pole piece winding drum moves by the fixing mechanism 1. The working process of the pole piece winding drum swing transfer device is as follows: First, the swing drive mechanism 4 drives the swing mechanism 2 to swing on the fixing mechanism 1, and the material taking mechanism 3 swings with the swing mechanism 2 to the pole piece winding drum material taking position (such as Figure 1 Then the material taking barrel 31 is inserted into the inner side of the pole piece winding barrel, and the support block driving assembly 33 drives the support block 32 to move radially in the mounting hole 311 so that the support block 32 clamps and fixes the pole piece winding barrel; then the swing driving mechanism 4 drives the swing mechanism 2 to swing on the fixing mechanism 1 to the recovery position (such as Figure 2 The support block driving assembly 33 releases the support block 32, so that the support block 32 releases the pole piece reel. Thus, the pole piece reel swing transfer device completes a round of pole piece reel swing transfer operation, and then the pole piece reel swing transfer device recycles the previous steps to perform the next round of pole piece reel swing transfer.

[0031] Embodiment 2

[0032] See also Figures 1 to 5 The pole piece reel swing transfer device of this embodiment is the same as that of the first embodiment as a whole, and the structure of the support block drive assembly 33 is improved on the basis of the first embodiment. For the similarities between this embodiment and the first embodiment, please refer to the first embodiment. The improved support block drive assembly 33 will be described below.

[0033] See also Figure 4The support block driving assembly 33 includes a telescopic driving member 331 and a driving rod 332. The driving rod 332 is swingably arranged on the material taking barrel 31 through a rotating shaft. The driving rod 332 is preferably arranged as an L-shaped structure and inserted into the material taking barrel 31. The telescopic driving member 331 is arranged on the swing mechanism 2, and the telescopic driving member 331 can adopt a telescopic cylinder. One end of the driving rod 332 is rotatably connected to the telescopic driving member 331 through a rotating shaft, and the other end of the driving rod 332 abuts against the support block 32. Thus, the telescopic driving member 331 can be extended and retracted to drive the driving rod 332 to swing, and the driving rod 332 swings to drive the support block 32 to move radially in the mounting hole 311, so that the support block 32 can be radially pushed out from the material taking barrel 31 to clamp the pole piece winding barrel. In addition, it is preferred that a first stop bolt 34 is provided on the outside of the material taking barrel 31, and the swing amplitude of the driving rod 332 is limited by the first stop bolt 34, so as to avoid the driving rod 332 swinging too much, resulting in the support block 32 being pushed out too far and damaging the pole piece winding barrel on the material taking barrel 31. Specifically, a mounting block can be provided at the end of the material taking barrel 31, and the first stop bolt 34 can be radially screwed on the mounting block at the end of the material taking barrel 31, so as to limit the swing amplitude of the driving rod 332 by the first stop bolt 34. Moreover, the swing amplitude of the driving rod 332 can be adjusted by the length of the first stop bolt 34 extending from the mounting block, and the driving rod 332 can be limited to different swing amplitudes, so as to tighten the pole piece winding barrel to different degrees.

The swing mechanism 2 is swingably arranged on the first mounting plate 11 at an end away from the second mounting plate 12 through a rotating shaft. One end of the swing driving mechanism 4 is rotationally connected to an end of the second mounting plate 12 away from the first mounting plate 11 through a rotating shaft, and the other end of the swing driving mechanism 4 is rotationally connected to an end of the swing mechanism 2 away from the material taking mechanism 3 through a rotating shaft. In this way, the swing driving mechanism 4 can drive the swing mechanism 2 to swing on the fixing mechanism 1.

[0037] See also Figure 1 and 2The fixing mechanism 1 also includes a first limit plate 13, which is arranged on the first mounting plate 11. The first limit plate 13 limits the swing angle of the swing mechanism 2 and blocks the swing mechanism 2 at the pole piece winding drum recovery position, thereby allowing the swing mechanism 2 to stop at the pole piece winding drum recovery position.

[0038] See also Figure 1 and 2 , the fixing mechanism 1 also includes a second limit plate 14, which is arranged on one end of the first mounting plate 11 away from the first limit plate 13, and the first limit plate 13 and the second limit plate 14 limit the swing range of the swing mechanism 2 to a fan-shaped range, one side of the fan-shaped range is the material taking position of the pole piece reel, and the other side of the fan-shaped range is the recovery position of the pole piece reel. The first limit plate 13 and the second limit plate 14 make the swing mechanism 2 stop at the material taking position of the pole piece reel, and the material taking mechanism 3 takes the pole piece reel; and make the swing mechanism 2 stop at the recovery position of the pole piece reel, and the material taking mechanism 3 unloads the pole piece reel. In this embodiment, the first limit plate 13 is arranged on one side of the first mounting plate 11, and the second limit plate 14 is arranged on one end of the first mounting plate 11 away from the first limit plate 13, and the swing mechanism 2 is limited to swing within a range of ninety degrees by the first limit plate 13 and the second limit plate 14. In practice, the swing mechanism 2 can also be limited to move within other ranges according to the requirements of the pole piece winding drum for taking out and recovering the pole piece.

[0039] See also Figure 1 and 2 In order to further fine-tune the swing range of the swing mechanism 2, a second stop bolt 15 is provided on the first limit plate 13 and / or the second limit plate 14 near the swing mechanism 2.

[0040] See also Figures 1 to 5 When the pole piece winding drum swing transfer device of this embodiment is used, the pole piece winding drum swing transfer device is installed at the position where the pole piece winding drum moves through the fixing mechanism 1. The working process of the pole piece winding drum swing transfer device is as follows: First, the swing drive mechanism 4 drives the swing mechanism 2 to swing on the fixing mechanism 1, and the material taking mechanism 3 swings with the swing mechanism 2 to the pole piece winding drum material taking position (such as Figure 1Then the material taking barrel 31 is inserted into the inner side of the pole piece winding barrel, and the support block driving assembly 33 drives the support block 32 to move radially in the mounting hole 311 so that the support block 32 clamps and fixes the pole piece winding barrel; then the swing driving mechanism 4 drives the swing mechanism 2 to swing on the fixing mechanism 1 to the recovery position (such as Figure 2 The support block driving assembly 33 releases the support block 32 to move so that the support block 32 releases the pole piece reel. Thus, the pole piece reel swing transfer device completes one round of pole piece reel swing transfer operation, and then the pole piece reel swing transfer device recycles the previous steps to perform the next round of pole piece reel swing transfer. The support block driving assembly 33 includes a telescopic driving member 331 and a driving rod 332. The support block driving assembly 33 drives the support block 32 to move radially by driving the driving rod 332 to swing through the telescopic driving member 331. The swing range of the swing mechanism 2 is limited by the first limit plate 13 and the second limit plate 14, and is fine-tuned by the second stop bolt 15 installed on the first limit plate 13 and the second limit plate 14.
