Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a cell flipping mechanism and a hot pressing production line. Background Technology

[0002] During the transfer of battery cells into the hot press, the horizontally arranged battery cells need to be converted into a vertically arranged state to fit the battery cell station inside the hot press. Currently, the entire structure is rotated by a first drive device, and each battery cell carrier is individually rotated in the opposite direction by multiple independently set second drive devices to maintain the horizontal bearing state of the battery cell carrier. This method requires high synchronization between the two drive devices, has high equipment and operation costs, and is prone to the risk of tilting during the overturning process. Utility Model Content

[0003] In view of this, the purpose of this application is to provide a cell flipping mechanism and a hot pressing production line to reduce the equipment cost and control difficulty of the cell flipping operation process.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A cell flipping mechanism, comprising:

[0006] A drive unit and a rotating assembly, wherein the drive unit is connected to the rotating assembly in a transmission manner to drive the rotating assembly to rotate between a first state and a second state;

[0007] The battery cell carrier and drive plate are provided. Several battery cell carriers are provided and are respectively hinged to the rotating assembly. Each battery cell carrier includes a bearing surface for bearing the battery cell. The drive plate is fixedly provided. Each battery cell carrier includes at least one active carrier that is hinged to the drive plate through a first link. The bearing surface of the active carrier is kept horizontal during the rotation of the rotating assembly through the first link. The remaining battery cell carriers are directly or indirectly hinged to the active carrier through a second link and are kept parallel to the active carrier through the second link.

[0008] As can be seen from the above technical solution, one aspect of this disclosure provides a battery cell flipping mechanism, which mainly includes a driving unit, a rotating assembly, a battery cell carrier, and a driving plate. The driving unit is connected to the rotating assembly to drive the rotating assembly to rotate between a first state and a second state, thereby realizing the attitude conversion of the rotating assembly. Several battery cell carriers are respectively hinged to the rotating assembly to follow its rotation. The driving plate is fixedly installed to provide a positioning reference for the battery cell carriers during their rotation with the rotating assembly. Specifically, at least one active carrier among the battery cell carriers is hinged to the driving plate via a first connecting rod, so that during the rotation of the active carrier following the rotating assembly, its bearing surface can be positioned using the fixedly installed driving plate as a positioning reference. The system is designed to maintain a horizontal position, thus providing stable support for the battery cells. The active carrier is hinged to other battery cell carriers via a second link to keep the bearing surfaces of the active carrier and other battery cell carriers parallel. This disclosure uses a single drive unit to drive the rotation of the rotating component, enabling it to switch between a first state and a second state. A fixed drive plate, in conjunction with the first link hinged at both ends, keeps the bearing surface of the active carrier horizontal. The second link hinged at both ends ensures the relative parallelism between the active carrier and other battery cell carriers. During the operation of the battery cell flipping mechanism, only the rotation angle of a single drive unit needs to be adjusted to achieve the switching of the battery cell bearing and feeding states. This eliminates the need for multiple rotation drive structures, reducing the cost and operational difficulty of the battery cell flipping mechanism. Attached Figure Description

[0021] The core of this application is to disclose a cell flipping mechanism and a hot pressing production line to reduce the equipment cost and control difficulty of the cell flipping operation process.

[0022] To enable those skilled in the art to better understand the present application, embodiments of the present application will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model described in the claims. Additionally, the complete content of the structures represented in the following embodiments is not limited to those necessary for the solution of the utility model described in the claims.

[0023] like Figure 1 and Figure 2 As shown, one aspect of this disclosure provides a battery cell flipping mechanism to simultaneously carry a plurality of parallel-supplyed battery cell materials and flip the battery cell materials into a vertically arranged state. Specifically, the battery cell flipping mechanism mainly includes a drive unit 10, a rotating assembly 20, a battery cell carrier 30, and a drive plate 40. The battery cell carrier 30 is used to carry the battery cells, while the rotating assembly 20 is a platform supporting the battery cell carrier 30. The drive unit 10 is drively connected to the rotating assembly 20 to drive the rotating assembly 20 to rotate between a first state and a second state, thereby switching the form of the rotating assembly 20. It should be noted that the drive unit 10 can be a commonly used rotating drive component such as a motor, cylinder, or electric motor.

[0024] Several battery cell carriers 30 are mounted on the battery cell carriers 30 and are respectively hinged to the rotating assembly 20. That is, each battery cell carrier 30 is rotatably mounted on the rotating assembly 20 through an independent rotating shaft and bearing seat structure. During the rotation of the rotating assembly 20 driven by the drive unit 10, the battery cell carrier 30 will follow the rotating assembly 20 to achieve height change.

[0025] Based on this, the drive plate 40 is fixedly mounted on a fixed structure such as a frame. Specifically, it is fixed relative to the rotating assembly 20, meaning that while the drive unit 10 drives the rotating assembly 20 to rotate, the drive plate 40 maintains a fixed position to provide a positioning reference for the cell carrier 30 as it rotates following the rotating assembly 20. Specifically, at least one of the cell carriers 30 is defined as an active carrier 310, such as... Figure 3 As shown, the active carrier 310 is hinged to the drive plate 40 via the first connecting rod 510. The bearing surface on the active carrier 310, where the battery cell is placed, is initially horizontal. As the active carrier 310 rotates following the rotating assembly 20, the hinge point between the first connecting rod 510 and the drive plate 40 is fixed, allowing the first connecting rod 510 to rotate in a circle with its hinge point on the drive plate 40 as its rotation center. Simultaneously, the hinge point of the active carrier 310 on the rotating assembly 20 also rotates in a circle with the rotation center of the rotating assembly 20 as its center. The rotational power of the active carrier 310 is provided by the rotating assembly 20, and the rotation angle traversed by the rotating assembly 20 is the same as the rotation angle traversed by the first connecting rod 510 with its hinge point on the drive plate 40 as its rotation center. This ensures that the bearing surface of the active carrier 310 remains horizontal throughout the rotation of the rotating assembly 20, thus maintaining stable support for the battery cell while changing its height.

[0026] Furthermore, for rotating components 20 with more cell carriers 30, all of which act as active carriers 310 and are hinged to the drive plate 40, the structure of the cell flipping mechanism becomes complex. Therefore, in some embodiments of this disclosure, other cell carriers 30 are hinged to the active carriers 310 via the second link 520. That is, the two ends of the second link 520 are respectively hinged to one active carrier 310 and another cell carrier 30. During the process of the active carrier 310 rotating in the opposite direction to the rotating component 20 via the first link 510 to maintain a horizontal state, it maintains a fixed relative position with the cell carriers 30 via the second link 520, thus keeping the bearing surfaces of the active carrier 310 and other cell carriers 30 parallel. This ensures that the other cell carriers 30 also have a horizontal bearing surface to provide stable support for the cells.

[0027] In the cell flipping mechanism provided in the above embodiments, the adjustment of the arrangement state of the cell carrier 30 is achieved by a single drive unit 10, that is, the single drive unit 10 drives the rotation of the rotating component 20 to achieve the switching between the first state and the second state.

[0028] It should be noted that the rotation process of the rotating component 20 between the first state and the second state requires passing through a horizontal state position and a vertical state position. When the rotating component 20 is in the horizontal state, it can carry the battery cell and drive the battery cell to achieve transfer. When the rotating component 20 is in the vertical state, it can realize the height adjustment of the battery cell and switch several horizontally arranged battery cells to a vertically arranged state, so as to meet the feeding of the hot press.

[0029] It should also be noted that, as Figure 2 As shown, in some embodiments of this disclosure, the first state of the rotating component 20 can be a horizontal state, while as... Figure 7 As shown, the second state of the rotating component 20 can be a vertical state. To reduce the risk of abnormal rotation and overturning of the rotating component 20, as... Figure 2 , Figure 6 and Figure 7 As shown, the drive unit 10 only drives the rotating assembly 20 to reciprocate within a range of 90 degrees, thereby avoiding interference between the various linkages and the cell carrier 30 during large-scale or reverse motion processes, and reducing the structural complexity of the cell flipping mechanism.

[0030] Furthermore, in the cell flipping mechanism, a fixed drive plate 40, in conjunction with a first connecting rod 510 hinged at both ends, maintains the bearing surface of the active carrier 310 horizontal. A second connecting rod 520 hinged at both ends achieves a relatively parallel state between the active carrier 310 and other cell carriers 30. During the flipping action of the cell flipping mechanism, only the rotation angle of a single drive unit 10 needs to be adjusted to switch the cell bearing and feeding states, eliminating the need for multiple coordinating rotation drive structures to achieve a horizontal state for the cell carrier 30. This not only reduces the structural complexity and equipment cost of the cell flipping mechanism but also lowers the operational difficulty and avoids drive structure failure issues during complex actions.

[0031] Furthermore, in some embodiments of this disclosure, in order to improve the structural uniformity of the cell flipping mechanism, the rotation center of the rotating component 20 is coaxially arranged with the center of the drive plate 40, and preferably the rotation center of the rotating component 20 is the midpoint of its length direction, and the drive plate 40 uses the midpoint of the rotating component 20 as a reference, while the active carrier 310 is kept in a parallel state by the first connecting rod 510.

[0032] It should be noted that setting the rotation center of the rotating component 20 at its midpoint ensures that the area covered by both sides of the midpoint during rotation is equal, thus improving rotational uniformity. Furthermore, the same number of cell carriers 30 can be installed on both sides of the midpoint of the rotating component 20, ensuring uniform force distribution at the connection shaft between the rotating component 20 and the drive unit 10. The drive plate 40, coaxially positioned with the midpoint of the rotating component 20, provides accurate midpoint reference positioning during the movement of the rotating component 20 through its fixed structure.

[0033] It should be noted that in some embodiments, one side of the drive plate 40 passes through the rotating assembly 20, and the area where the drive plate 40 passes through the rotating assembly 20 is rotatably engaged with the rotating assembly 20 through the bearing seat to maintain the fixed structure of the drive plate 40. At the same time, it provides a support point for the rotating assembly 20 at its rotation center position, so that the rotating assembly 20 is stably supported by the bearing seat during rotation and will not have the risk of rotation center shift or falling, thereby improving the operational stability of the cell flipping mechanism.

[0034] Meanwhile, the cell carrier 30 is provided with at least two symmetrically arranged about the rotation center of the rotating component 20 to ensure the load-bearing capacity of the cell flipping mechanism and to maintain a symmetrical structure on both sides of the rotation center of the rotating component 20, thereby reducing the risk of skewing of the rotating component 20 due to uneven force on both sides during rotation.

[0035] Similarly, in some embodiments, multiple cell carriers 30 are provided to enhance the cell-carrying and transporting capacity of the cell flipping mechanism. Based on this, the cell carriers 30 hinged on the rotating assembly 20 can be divided into two groups and independently connected. Specifically, independent connection means that there is no linkage between the two groups of cell carriers, while each group of cell carriers 30 achieves hinged engagement through connections. That is, the cell carriers 30 located on one side of the rotating assembly 20 form one group, and the drive plate 40 and its adjacent cell carriers 30 are respectively hinged through the first link 510. In other words, the cell carriers 30 closest to the drive plate 40 in both groups are designated as active carriers 310 and are hinged to the drive plate 40. The remaining cell carriers 30 are hinged to the active carriers 310 within their respective groups through the second link 520 to achieve a relatively parallel arrangement. The grouped battery cell carrier 30 can reduce the complexity of the linkage setup. The connection distance from the active carrier 310 to the farthest battery cell carrier 30 is reduced, thus avoiding the problem of the second linkage 520 being too long and unable to rotate due to a dead point during rotation.

[0036] Based on the above embodiments, such as Figure 4As shown, taking a single active vehicle 310 as an example, specifically, the hinge point between the first link 510 and the active vehicle 310 is defined as A, the hinge point between the first link 510 and the drive plate 40 is defined as B, the hinge point of the active vehicle 310 on the rotating assembly 20 is defined as C, and the rotation center of the rotating assembly 20 is defined as D. To improve the stability of the active vehicle 310 during rotation, it is preferable that hinge points A, B, C, and the rotation center D are set on the same plane. In this embodiment, the connecting lines AB and CD are set to be parallel and equal to form a parallelogram-shaped linkage motion structure, and the active vehicle 310 is kept in place during movement by means of two fixed hinge points. In a horizontal state; it should be noted that during the process of assembling the active carrier 310 on the rotating assembly 20, the bearing surface on the active carrier 310 is set to a horizontal state. As for the connecting line AB, since the drive plate 40 is fixedly set, the first connecting rod 510 and the hinge point B of the drive plate 40 remain fixed in position at any rotation angle of the rotating assembly 20. The first connecting rod 510 rotates in a circle with the hinge point B as the rotation center. Similarly, since the hinge point C is located on the rotating assembly 20 and the rotation center D is fixed, the connecting line CD rotates in a circle with the rotation center D as the center during the rotation of the rotating assembly 20, and the rotation angle is the same as that of the connecting line AB. Therefore, in parallelogram ABCD, AB and CD are always parallel and equal, and the relative positions of points B and D remain fixed. Similarly, during the rotation of the rotating component 20 at any angle, the relative positions of points A and C also remain fixed. Points A and C are both hinge points on the active carrier 310. The fixed relative positions of the two enable the active carrier 310 to maintain the same horizontal state as the initial state during the rotation of the rotating component 20 at any angle, and to maintain a stable bearing effect on the battery cell during the height adjustment process.

[0037] Furthermore, in some embodiments of this disclosure, the drive plate 40, which is provided with active carriers 310 on both sides, is configured with a Z-shaped structure, and the first connecting rods 510 on both sides are respectively hinged to the two ends of the drive plate 40, so that the hinge points of the first connecting rods 510 on both sides on the drive plate 40 have different vertical heights. During the rotation of the rotating assembly 20, the support force points provided by the drive plate 40 to the first connecting rods 510 on both sides are located at different heights, which can avoid the risk of dead points when the first connecting rods 510 start to rotate; at the same time, it can also make the first connecting rods 510 set in a horizontal state and connected to different height positions on different active carriers 310, so that when the active carrier 310 is connected to other cell carriers 30 through the second connecting rod 520, the second connecting rod 520 and the first connecting rod 510 have different vertical heights, thus meeting the independent rotation requirements of each cell carrier 30.

[0038] Furthermore, in the cell flipping mechanism provided in this embodiment, the connection structure between the active carrier 310 and other cell carriers 30, such as... Figure 5 As shown, taking the example of two cell carriers 30 arranged on one side of the rotation center of the rotating assembly 20, the hinge points of the two cell carriers 30 on the rotating assembly 20 are E and F, respectively. It should be noted that hinge points E and F are both located on the rotating assembly 20. Therefore, during the rotation of the rotating assembly 20, the connecting line EF remains unchanged in size. The hinge points of the second link 520 on the two cell carriers 30 are G and H, respectively. Similarly, the length of the second link 520 is set so that the connecting line GH is the same as the connecting line EF. When the cell carriers 30 are assembled on the rotating assembly 20, the connecting line EF is restricted to be parallel to the connecting line GH. The hinge position of the second link 520 is set so that the lengths of EG and FH are the same, so that the quadrilateral EFGH forms a parallelogram. Based on this, during the rotation of the rotating assembly 20 to drive the cell carrier 30 to achieve vertical height adjustment, the cell carrier 30, as the active carrier 310, remains horizontal due to its hinge connection with the drive plate 40 via the first connecting rod 510. Therefore, hinge point F and hinge point H of the second connecting rod 520 on the active carrier 310 maintain a fixed relative position. Simultaneously, since connecting lines EF and GH remain equal during rotation, hinge points E and G on the cell carrier 30 on one side of the active carrier 310 also maintain a fixed relative position. That is, while the active carrier 310 remains parallel, the cell carrier 30 on one side of the active carrier 310 also maintains a parallel state with the active carrier 310, thus ensuring stable support for the cell. The above structures all achieve horizontal support for the active carrier 310 and the cell carrier 30 during rotation through the hinge structure of the connecting rods, reducing the difficulty of adjustment without the need for other drive structures.

[0039] Furthermore, based on the above embodiments, for the driven cell carrier 30, it is simultaneously hinged with a first link 510 and a second link 520. In order to improve the uniformity of force distribution, it is preferable that the hinge points of the first link 510 and the second link 520 are located at diagonal positions on the connecting plate of the cell carrier 30. The connecting plate is a plate support structure that hinges the cell carrier 30 to the rotating assembly 20. When the rotating assembly 20 is in the cell conveying state, the first link 510 and the second link 520 have different vertical heights. When the rotating assembly 20 is in the cell height adjustment state, the first link 510 and the second link 520 have different horizontal positions. This ensures that the first link 510 and the second link 520 are always subjected to staggered force on the cell carrier 30, thereby reducing the risk of skewing due to unilateral force distribution on the cell carrier 30.

[0040] In some embodiments, the connecting plate of the cell carrier 30 has a rectangular structure, and the hinge points of the first link 510 and the second link 520 are located on the same diagonal line driven by the connecting plate, and are symmetrical about the center of the connecting plate.

[0041] Furthermore, in order to improve the uniformity of force on the rotating component 20 in the cell flipping mechanism with multiple cell carriers 30, the hinge points of the cell carriers 30 on the rotating component 20 are set at equal intervals. At the same time, when the rotating component 20 moves to a vertical position to feed into the hot press, the bearing surfaces of the multiple cell carriers 30 are spaced at the same distance in the vertical direction, so as to be compatible with the hot pressing stations with the same height spacing in the hot press.

[0042] For the rotating assembly 20, which is horizontal in the first state and vertical in the second state, it is preferable that when the rotating assembly 20 is in the first state, the first link 510 and the second link 520 are also in a horizontal state, so that the first link 510 and the second link 520 will not have the risk of abnormal rotation due to the tilt state; while when the rotating assembly 20 is in the second state, the first link 510 and the second link 520 are both in a vertical state, so as to generate a vertical force with the cell carrier 30, and be parallel to the arrangement direction of the vertically arranged cell carrier 30 to improve the stability of the cell carrier 30.

[0043] Furthermore, in order to improve the structural compactness of the cell flipping mechanism and reduce the risk of motion interference, in some embodiments, the first link 510 and the second link 520 are arranged on the same plane in the thickness direction of the rotating component 20, so that the rotation process of both under force is realized in the same plane, thereby reducing the force complexity of the cell flipping mechanism. Along the thickness direction of the drive plate 40, the first link 510 and the second link 520 are both arranged between the drive plate 40 and the rotating component 20 to utilize the gap between the drive plate 40 and the rotating component 20 to avoid interference. At the same time, the first link 510 and the second link 520 are protected by the drive plates 40 and the rotating component 20 on both sides as built-in structures, reducing the risk of impact damage to the first link 510 and the second link 520.

[0044] Furthermore, in the cell flipping mechanism provided in the embodiments of this disclosure, such as Figure 8 and Figure 9As shown, the battery cell carrier 30 specifically includes a base plate 320 to form a bearing surface, providing a flat mounting plane for the battery cell and effectively supporting it. Simultaneously, four blocking blocks 330 are arranged circumferentially on the base plate 320. Preferably, the four blocking blocks 330 are located on the four sides of the rectangular structure. After the battery cell is supported on the base plate 320, the four blocking blocks 330 can abut and limit the battery cell from four circumferential positions, preventing the battery cell from slipping on the base plate 320 and ensuring that the battery cell carrier 30 maintains a stable bearing effect on the battery cell during height adjustment.

[0045] Based on the above embodiments, to reduce the difficulty of setting the battery cell on the battery cell carrier 30, in some embodiments, the blocking block 330 includes a fixed blocking block 3310 and three movable blocking blocks 3320. The fixed blocking block 3310 is fixed relative to the base plate 320, while the three movable blocking blocks 3320 can move closer to and away from the center of the base plate 320. When a battery cell needs to be placed, the three movable blocking blocks 3320 are adjusted to move away from the center of the base plate 320 so that the rectangular area enclosed by the four blocking blocks 330 is larger than the battery cell, allowing the battery cell to be smoothly placed on the top of the base plate 320. After the battery cell is successfully placed on the base plate 320, the three movable blocking blocks 3320 can be adjusted to move closer to the center of the base plate 320 until the three movable blocking blocks 3320 abut against the side wall of the battery cell to achieve limiting and locking of the battery cell. The above structure enables the battery cell carrier 30 to effectively limit and lock battery cells of different sizes, thereby improving the versatility of the battery cell flipping mechanism.

[0046] Furthermore, in the above embodiments, the three moving blocks 3320 can be driven independently or moved synchronously. To reduce the structural complexity of the cell flipping mechanism, in some embodiments, the three moving blocks 3320 are configured as a synchronous operation structure. Specifically, the three moving blocks 3320 are slidably disposed on the linear moving guide rail 3330, and one of the moving blocks 3320, preferably the moving block 3320 opposite to the fixed block 3310, is connected to a drive motor 3340. Here, "opposite" specifically refers to the remaining moving block 3320 after removing the two moving blocks 3320 symmetrically located on both sides of the fixed block 3310. Meanwhile, the movable blocks 3320 located on both sides of the fixed block 3310 are respectively hinged to the movable block 3320 in the middle position through connecting rods. When the drive motor 3340 drives the movable block 3320 in the middle position to move, the movable blocks 3320 on both sides are driven by the connecting rods to move synchronously away from and towards the center of the bottom support plate 320.

[0047] Furthermore, in another aspect of this disclosure, a hot-pressing production line is also provided, which includes the cell flipping mechanism provided in any of the above embodiments, and a hot-pressing device for hot-pressing the cells. It should be noted that since the cell flipping mechanism has the technical effects provided in any of the above embodiments, the hot-pressing production line also has the technical effects provided in any of the above embodiments, and will not be repeated here.
