[0039] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments.

[0040] Figure 1 This is a schematic diagram of a dust removal and cell flattening device according to an embodiment of this application. Figure 2 This is a schematic diagram of a battery cell flattening device according to an embodiment of this application. Figure 3 This is a cross-sectional schematic diagram of a first annular coil and a second annular coil according to an embodiment of this application. Figure 4 This is a schematic diagram of a kneading component according to an embodiment of this application, in conjunction with... Figures 1-4 As shown:

[0041] This application discloses a dust removal battery cell smoothing device 10, which includes a main support 100 and a battery cell smoothing device 200. The battery cell smoothing device 200 is rotatably connected to the main support 100. The battery cell smoothing device 200 includes a rotating drum 210, a plurality of battery cell fixing components 220 and a plurality of smoothing components 230. The battery cell fixing components 220 and the smoothing components 230 are all disposed on the surface of the rotating drum 210.

[0042] The kneading assembly 230 includes a longitudinal moving assembly 310, a rotary driving assembly 320, and a kneading wheel assembly 330; the longitudinal moving assembly 310 is disposed on the surface of the rotating drum 210, the rotary driving assembly 320 is connected to the longitudinal moving assembly 310, and the kneading wheel assembly 330 is connected to the rotary driving assembly 320.

[0043] The cell fixing assembly 220 is used to fix the cell 11; the longitudinal moving assembly 310 is used to drive the rotary driving assembly 320 to move, so that the flattening wheel assembly 330 moves toward or away from the cell fixing assembly 220, the rotary driving assembly 320 is used to drive the flattening wheel assembly 330 to rotate, and the flattening wheel assembly 330 is used to flatten one end of the cell 11.

[0044] The dust removal battery cell flattening device 10 also includes a dust removal bottom cover 410, a dust removal top cover 420, an external dust removal pipe 430, a first annular coil 441, a second annular coil 442, and a dust extraction pipe 450. One end of the dust removal bottom cover 410 is connected to the rotary drive assembly 320, and the other end covers the flattening wheel assembly 330. The dust removal top cover 420 is connected to the side of the dust removal bottom cover 410 away from the rotary drive assembly 320. A battery cell inlet 460 is provided on the side of the dust removal top cover 420 away from the dust removal bottom cover 410.

[0045] The first annular coil 441 is fixedly connected to the rotating drum 210, meaning that the first annular coil 441 can rotate with the rotating drum 210. The second annular coil 442 is rotatably connected to the first annular coil 441. The internal space of the first annular coil 441 is connected to the internal space of the second annular coil 442. The two ends of the external dust removal pipe 430 are respectively connected to the dust removal bottom cover 410 and the first annular coil 441. One end of the dust extraction pipe 450 is connected to the second annular coil 442, and the other end is used to connect to the fan.

[0046] For example, when it is necessary to flatten the battery cell 11, the battery cell 11 is installed on the battery cell fixing assembly 220. The longitudinal moving assembly 310 drives the rotary driving assembly 320 to move, so that the flattening wheel assembly 330 moves toward the direction close to the battery cell fixing assembly 220, and one end of the battery cell 11 is inserted into the battery cell inlet 460. The rotary driving assembly 320 drives the flattening wheel assembly 330 to rotate, and the flattening wheel assembly 330 flattens one end of the battery cell 11. Then, when flattening, the fan is turned on so that the debris generated during flattening can fall into the dust removal bottom cover 410 and the dust removal top cover 420, and then be discharged through the external dust removal pipe 430, the first annular coil 441, the second annular coil 442 and the dust extraction pipe 450.

[0047] Compared to existing dust-removing battery cell leveling equipment, the dust-removing battery cell leveling equipment 10 of this application is equipped with a dust-removing bottom cover 410 and a dust-removing top cover 420 to partially surround the leveling roller assembly 330. An external dust-removing pipe 430 is provided to suck up the debris generated during leveling into the first annular coil 441 and the second annular coil 442. The first annular coil 441 can rotate with the rotating drum 210, and the second annular coil 442 is rotatably connected to the first annular coil 441. Thus, all the external dust-removing pipes 430 on the side of the battery cell fixing assembly 220 can be connected to the first annular coil 441 and discharged along the second annular coil 442 and the dust extraction pipe 450, thereby improving the dust removal effect of the dust-removing battery cell leveling equipment 10.

[0048] Since the kneading component 230 needs to move, the exemplary external dust removal pipe 430 can be a retractable flexible hose. Alternatively, the external dust removal pipe 430 can include a first rigid pipe 431, a retractable pipe, and a second rigid pipe 433, which are connected in sequence. The end of the first rigid pipe 431 away from the retractable pipe is connected to the dust removal bottom cover 410, and the end of the second rigid pipe 433 away from the retractable pipe is connected to the first annular coil 441.

[0049] By setting up a first rigid tube 431 and a second rigid tube 433, and then connecting the first rigid tube 431 and the second rigid tube 433 with a telescopic tube, it is easier to replace and repair them.

[0050] The cell fixing assembly 220 has a flattening assembly 230 on both sides, which are respectively defined as the first flattening assembly 231 and the second flattening assembly 232. The cell fixing assembly 220 is used to fix the cell 11; the first flattening assembly 231 flattens one end of the cell 11, and the second flattening assembly 232 flattens the other end of the cell 11, thereby improving the flattening efficiency.

[0051] More importantly, both the first kneading component 231 and the second kneading component 232 are equipped with a dust removal bottom cover 410, a dust removal top cover 420, an external dust removal pipe 430, a first annular coil 441, a second annular coil 442 and a dust extraction pipe 450 for dust removal.

[0052] The inner diameter of the dust removal bottom cover 410 gradually increases along the direction towards the battery cell fixing assembly 220; the inner diameter of the dust removal top cover 420 gradually decreases along the direction towards the battery cell fixing assembly 220. This combination of the dust removal bottom cover 410 and the dust removal top cover 420 creates a structure that is smaller at both ends and larger in the middle, causing debris to concentrate in the center. The external dust removal pipe 430 can then be connected to the side of the dust removal bottom cover 410 closest to the dust removal top cover 420, allowing dust to more easily enter the external dust removal pipe 430.

[0053] Furthermore, the slope of the inner wall of the dust removal bottom cover 410 is less than that of the inner wall of the dust removal top cover 420. This increases the probability that the debris generated by kneading will slide off the inner wall of the dust removal top cover 420, thereby further preventing the debris from adhering to the dust removal top cover 420 and being unable to enter the external dust removal pipe 430.

[0054] The dust removal battery cell flattening device 10 also includes a semi-circular storage cover 530, which is connected to the main support 100. The semi-circular storage cover 530 is located between the battery cell flattening device 200 and the main support 100, and the orthographic projection of the semi-circular storage cover 530 on the main support 100 covers the orthographic projection of the battery cell fixing assembly 220 on the main support 100.

[0055] The semi-circular storage cover 530 can not only collect debris and dust that have come out of the cell inlet 460, but also prevent the cell 11 from being thrown out when the rotating drum 210 rotates because the cell fixing component 220 does not clamp the cell 11 properly. This reduces the probability of production accidents.

[0056] Figure 5 This is a schematic diagram of a hollow rotating shaft according to an embodiment of this application, in conjunction with... Figures 2-5 As shown, the kneading wheel assembly 330 includes a hollow rotating shaft 331, a kneading wheel base 332, and a kneading wheel 333. The kneading wheel base 332 is connected to the hollow rotating shaft 331, and the kneading wheel 333 is connected to the side of the kneading wheel base 332 opposite to the hollow rotating shaft 331. The kneading wheel base 332 is provided with a base through hole, and the hollow rotating shaft 331 is connected to the base through hole. The rotation drive assembly 320 is connected to the hollow rotating shaft 331 and is used to drive the hollow rotating shaft 331 to rotate.

[0057] The dust removal battery cell flattening device 10 also includes a dust removal shaft cover 510 and an inner dust removal pipe 520. The dust removal shaft cover 510 is connected to the rotary drive assembly 320, and one end of the dust removal shaft cover 510 covers the side of the hollow rotating shaft 331 away from the flattening wheel base 332. The other end of the dust removal shaft cover 510 is connected to the inner dust removal pipe 520 through a telescopic tube. The side of the inner dust removal pipe 520 away from the dust removal shaft cover 510 is connected to the outer dust removal pipe 430.

[0058] The internal dust removal system of the hollow rotating shaft 331, together with the external dust removal system consisting of the dust removal bottom cover 410 and the dust removal top cover 420, collects the debris extracted from the hollow rotating shaft 331 and the debris extracted from the dust removal bottom cover 410 and the dust removal top cover 420. This improves the dust removal effect and reduces the design of pipelines, thus simplifying the structure of the dust removal battery cell flattening equipment 10.

[0059] Figure 6 This is a schematic diagram of a dust removal and battery cell leveling device according to an embodiment of this application, including a battery cell transfer turntable assembly. Figure 6 As shown, the dust removal battery cell flattening device 10 also includes five battery cell transfer turntable assemblies 600. The battery cell flattening device 200 is horizontal, and the five battery cell transfer turntable assemblies 600 are also horizontal. The four battery cell transfer turntable assemblies 600 are respectively defined as the first feeding turntable assembly 611, the second feeding turntable assembly 612, the first discharging turntable assembly 621, the second discharging turntable assembly 622, and the third discharging turntable assembly 623.

[0060] The first feeding turntable assembly 611, the second feeding turntable assembly 612, the first unloading turntable assembly 621, the second unloading turntable assembly 622, and the third unloading turntable assembly 623 are all rotatably connected to the main support 100.

[0061] The second feeding turntable assembly 612 is located between the first feeding turntable assembly 611 and the cell flattening device 200. The first feeding turntable assembly 611 is used to transfer the cell 11 to the second feeding turntable assembly 612, and the second feeding turntable assembly 612 is used to transfer the cell 11 to the cell flattening device 200. The cell flattening device 200 is used to flatten the cell 11.

[0062] The first feeding turntable assembly 621 is located on the side of the cell flattening device 200 away from the second feeding turntable assembly 612, the second feeding turntable assembly 622 is located on the side of the first feeding turntable assembly 621 away from the cell flattening device 200, and the third feeding turntable assembly 623 is located on the side of the second feeding turntable assembly 622 away from the first feeding turntable assembly 621.

[0063] The first feeding turntable assembly 621 is used to transfer the flattened battery cell 11 on the battery cell flattening device 200 to the second feeding turntable assembly 622, and the second feeding turntable assembly 622 is used to receive the battery cell 11 on the first feeding turntable assembly 621; the third feeding turntable assembly 623 is used to receive the battery cell 11 on the second feeding turntable assembly 622.

[0064] Simply put, the battery cells 11 in the battery cell transfer turntable assembly 600 and the battery cells 11 in the battery cell flattening device 200 are in a horizontal position.

[0065] For example, the first feeding turntable assembly 611 rotates clockwise to clamp the battery cell 11 and transfers it to a position close to the second feeding turntable assembly 612; the second feeding turntable assembly 612 rotates counterclockwise to receive the battery cell 11 on the first feeding turntable assembly 611 and transfers it to a position close to the battery cell flattening device 200; after the battery cell 11 is flattened and transferred, the battery cell flattening device 200 rotates clockwise and flattens the battery cell 11 simultaneously, and transfers it to a position close to the bottom of the first unloading turntable assembly 621; the first unloading turntable assembly 621 rotates counterclockwise to a position close to the battery cell flattening device 200 to clamp the flattened battery cell 11 and transfers it to a position close to the second unloading turntable assembly 622; the second unloading turntable assembly 622 moves clockwise to a position close to the first unloading turntable assembly 621 to clamp the battery cell 11 inside the first unloading turntable assembly 621.

[0066] The battery cell 11 is transferred from the first feeding turntable assembly 611 to the second feeding turntable assembly. The battery cell flattening device 200 flattens the battery cell 11. The first unloading turntable assembly 621 transfers the flattened battery cell 11 from the battery cell flattening device 200 to the second unloading turntable assembly 622. The second unloading turntable assembly 622 is used to receive the battery cell 11 from the first unloading turntable assembly 621, thereby realizing the transfer and flattening process of the battery cell 11 and improving the flattening efficiency of the battery cell 11.

[0067] Moreover, compared to vertical dust removal and cell leveling equipment, the cell leveling device 200 in the dust removal and cell leveling equipment 10 of this application is horizontal, and the cell transfer turntable assembly 600 is also horizontal. That is, the cell 11 is always in a horizontal state. In this way, when the cell 11 is transferred to the cell leveling device 200, it is not easy for the cell 11 to be displaced along the length direction of the cell 11 during the transfer process because the gravity direction of the cell 11 and the length direction of the cell 11 are in the same vertical direction, thereby improving the accuracy of leveling the cell 11.

[0068] Furthermore, by setting up the third feeding turntable assembly 623, the distance between the end feeding position of the dust removal battery cell flattening equipment 10 and the battery cell flattening device 200 is extended, making it more convenient to carry out maintenance and other procedures on the battery cell flattening device 200.

[0069] Figure 7 This is a schematic diagram of a cell transfer turntable assembly according to an embodiment of this application. Figure 8 This is a schematic diagram of a gripper according to an embodiment of this application. Figure 9 This is a plan view of a cam disk according to an embodiment of this application, combined with... Figures 6-9 As shown:

[0070] The cell transfer turntable assembly 600 includes a rotating shaft 641, a cam disk 642, a gripper fixing disk 643, multiple grippers 644, an outer baffle 645, and an inner baffle 646. The cam disk 642 is fixedly connected to the main support 100. The rotating shaft 641 passes through the cam disk 642 and is rotatably connected to the main support 100. The gripper fixing disk 643 is coaxially connected to the rotating shaft 641. The multiple grippers 644 are all located on the side of the gripper fixing disk 643 near the cam disk 642, and the multiple grippers 644 are equidistantly arranged on the edge of the gripper fixing disk 643, and the multiple grippers 644 surround the cam disk 642.

[0071] Both the outer baffle 645 and the inner baffle 646 are connected to the rotating shaft 641. The outer baffle 645 is located on the side of the gripper fixing plate 643 away from the cam plate 642, and the inner baffle 646 is located on the side of the cam plate 642 away from the gripper fixing plate 643. The outer baffle 645 and the inner baffle 646 are provided with arc-shaped recesses 647 corresponding to the positions of the gripper 644. The arc-shaped recesses 647 are used to lock the battery cells 11 that are stuck together to separate, thereby facilitating the gripping of the gripper 644.

[0072] The rotating shaft 641 rotates to drive the gripper fixing disk 643 to rotate, and causes the multiple grippers 644 to rotate around the cam disk 642. When the cam disk 642 abuts against the grippers 644, the grippers 644 are in an open state; when the cam disk 642 separates from the grippers 644, the grippers 644 are in a clamping state.

[0073] The dust removal battery cell flattening device 10 further includes a feeding conveyor belt 710, a discharging conveyor belt 720, and a battery cell holder. The feeding conveyor belt 710 is located below the first feeding turntable assembly 611, the discharging conveyor belt 720 is located below the third discharging turntable assembly 623, and the battery cell holder is located on the feeding conveyor belt 710 and the discharging conveyor belt 720. The battery cell holder is used to place the battery cell 11, the feeding conveyor belt 710 is used to transport the battery cell 11, and the discharging conveyor belt 720 is used to transport the battery cell 11 coming down from the third discharging turntable assembly 623.

[0074] In simple terms, the cam disk 642 is fixed on the main support 100, and the rotating shaft 641 and the gripper fixing disk 643 are rotatable, thereby driving multiple grippers 644 to rotate around the cam disk 642. The distance from the edge of the cam disk 642 to the center of the rotating shaft 641 is different, that is, the cam disk 642 has a convex position and a concave position. In the convex position, it can abut against the gripper 644, so that the gripper 644 is in the open state; in the concave position, it will not abut against the gripper 644, so that the gripper 644 is in the clamping state.

[0075] When the gripper fixing disk 643 rotates, the gripper 644 can be in a latching state to a clamping state when it passes the position where the battery cell 11 needs to be clamped, thereby clamping the battery cell 11. When it passes the position where the battery cell 11 needs to be put down, the gripper 644 can be in a latching state, thereby putting down the battery cell 11.

[0076] Thus, by controlling the rotation of the gripper fixing plate 643, the gripper 644 can be in a clamping state to a tight state when passing the position where the battery cell 11 needs to be clamped, thereby clamping the battery cell 11. When passing the position where the battery cell 11 needs to be put down, the gripper 644 can be in a clamping state, thereby putting down the battery cell 11. This further simplifies the dust removal battery cell flattening equipment 10 and reduces the production cost of the dust removal battery cell flattening equipment 10.
