Description

Transplanting equipment, battery cell charging and discharging equipment, battery cell carriers and overhead cranes

[0001] This application claims priority to Chinese patent applications No. 202411612415.4, No. 202422757109.1, and No. 202422757101.5, all of which are incorporated herein by reference. Technical Field

[0002] This application relates to a transplanting device, a battery cell charging and discharging device, a battery cell carrier, a battery cell carrier transplanting device, a battery cell carrier transport crane, and a transplanting apparatus. Background Technology

[0003] Cell formation testing is a crucial step in battery production, directly impacting cell performance and quality. To automate cell formation testing, automated production lines are used for cell transport. Currently, overhead cranes are typically used to transfer pouch cells to fixtures for formation testing, directly gripping and handling them. However, this handling process is prone to instability and carries a high risk of cell damage. This is especially true for pouch cells without air bags, which require more stringent handling conditions; direct handling with current transfer devices easily damages these cells.

[0004] To avoid damage to the airless pouch cells during handling, they are typically first transferred to a cell carrier, and then transported to the next processing station using a transfer device. The cell carrier is equipped with a retractable support module for loading the cells; the module holds the cells in its unfolded state. However, existing cell carriers often struggle to maintain this unfolded state, increasing the risk of damage during cell handling. On the other hand, for the formation and testing process, overhead cranes are used to transport the cells. However, existing overhead cranes have multiple lifting grippers, allowing for the simultaneous handling of multiple air-bagged pouch cells. This type of crane is relatively complex and expensive, primarily suitable for handling air-bagged pouch cells, and cannot effectively meet the higher safety requirements for handling airless pouch cells.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0050] In the description of this application, the terms “X direction”, “Y direction” and “Z direction” are all determined based on the Cartesian coordinate system constructed by the battery cell production line provided in this application. Among them, “Z direction” is also the up and down direction.

[0051] Figure 1 is a schematic diagram of a battery cell charging and discharging device according to one embodiment of this application. Figure 2 is a schematic diagram of the cooperation between the overhead crane 120 and the battery cell carrier 300 in Figure 1. Referring to Figure 1, the battery cell charging and discharging device includes a transfer device, a material flow line 500, and a loading and unloading device 600.

[0052] The transplanting equipment includes a crane assembly 100, a transfer device 200, and a battery cell carrier 300. The crane assembly 100 includes a crane track 110 and a transport crane 120. The crane track 110 extends along the Y direction, and the transport crane 120 is movably connected to and can move along the crane track 110. The transfer device 200 is located below the crane track 110 and the transport crane 120.

[0053] Referring to Figure 2, the cell carrier 300 includes a lifting frame 310 and a cell support module 320. The cell support module 320 is connected to the lifting frame 310 and is configured to switch between an extended state and a retracted state. The cell support module 320 is used to load the cell. The lifting frame 310 can be lifted by the overhead crane 120 to move the cell carrier 300 and place or detach the cell carrier 300 from the transfer device 200.

[0054] In this embodiment, the transplanting equipment includes at least a crane device 100, a transfer device 200, and a battery cell carrier 300. The main function of the transplanting device is to realize the transplantation and transfer of battery cells, and to switch the battery cells between different workstations.

[0055] Specifically, the transfer device 200 is located below the overhead crane device 100, the battery cell carrier 300 is used to load the battery cells and can be placed in the transfer device 200, and the overhead crane device 100 can lift and move the battery cell carrier 300 to move the battery cells in the battery cell carrier 300 to different work positions.

[0056] The overhead crane device 100 includes at least an overhead crane track 110 and a transport crane 120. The transport crane 120 is movably connected to the overhead crane track 110 and can move along the overhead crane track 110, that is, the transport crane 120 has a Y-direction degree of freedom of movement.

[0057] In addition, the cell carrier 300 includes at least a lifting frame 310 and a cell support module 320. The cell support module 320 is used to load the cell, and the lifting frame 310 can cooperate with the overhead crane 120 to lift the entire cell carrier 300. Moreover, the cell support module 320 can switch between an extended state and a retracted state. In the extended state, the loading and unloading device 600 can place the cell into the cell support module 320; in the retracted state, the cell placed in the cell support module 320 can be fixed, reducing the risk of damage to the cell due to shaking during transportation.

[0058] In this way, the overhead crane 120 can lift the battery cell carrier 300, which can place the battery cell carrier 300 in the transfer device 200 or lift the battery cell carrier 300 out of the transfer device 200. It can also move the battery cell carrier 300 and all the battery cells together along the Y direction, thereby moving and placing the battery cells at different workstations.

[0059] As can be seen, in the transplanting equipment provided in this application, the overhead crane device 100, in conjunction with the cell carrier 300, indirectly transports the battery cells, and the transfer device 200 serves as a transfer station for the cell carrier 300 during the battery cell transport process. In this application, the overhead crane device 100 does not directly act on the battery cells to achieve transport; instead, it loads the battery cells onto the cell carrier 300, and then the overhead crane device 100 moves the cell carrier 300 to achieve the transfer of the battery cells.

[0060] By adding an additional cell carrier 300 and cooperating with a newly designed overhead crane device 100, the transfer of cell is achieved. Due to the support and protection provided by the cell carrier 300, the stability during the handling process is improved, and the risk of damage to the cell during the handling process can be greatly reduced.

[0061] It should be noted that, depending on whether or not they have air bags, soft-pack batteries can be divided into soft-pack batteries with air bags and soft-pack batteries without air bags. The existing overhead cranes that use air bags for handling are not suitable for soft-pack batteries without air bags. Therefore, the transplanting equipment provided in this application is mainly suitable for handling soft-pack batteries without air bags.

[0062] Referring to Figure 1, optionally, at least a portion of the logistics line 500 is located on one X-direction side of the transplanting equipment and forms multiple loading / unloading stations 510, each loading / unloading station 510 corresponding to a transfer device 200 and a loading / unloading device 600. The logistics line 500 is provided with a battery cell transfer tray 700 at the loading / unloading station 510.

[0063] The loading / unloading device 600 is used to transport battery cells and place them in the battery cell carrier 300 in the transfer device 200 or the battery cell transfer tray 700 located at the loading / unloading station 510. That is, the loading / unloading device 600 is used to transport battery cells, and the loading / unloading device 600 also places the battery cells in the battery cell carrier 300 in the transfer device 200, or places the battery cells in the battery cell transfer tray 700 located at the loading / unloading station 510.

[0064] In this embodiment, the logistics line 500 is used to transport the battery cell transfer tray 700, which can load battery cells and dock at the loading / unloading station 510 on the logistics line 500.

[0065] Each loading / unloading station 510 is equipped with a transfer device 200 and a loading / unloading device 600. When the battery cell carrier 300 is placed in the transfer device 200, the loading / unloading device 600 transports the battery cells in the battery cell transfer tray 700 to the battery cell carrier 300, or transports the battery cells in the battery cell carrier 300 to the battery cell transfer tray 700.

[0066] In the embodiment shown in Figure 1, there are two loading and unloading stations 510, one of which is the loading station 511 and the other is the unloading station 512. The transfer device 200 corresponding to the loading station 511 is the loading transfer device 20a, and the transfer device 200 corresponding to the unloading station 512 is the unloading transfer device 20b.

[0067] It should be understood that the loading / unloading device 600 corresponding to the loading station 511 is used to transport the battery cells in the battery cell transfer tray 700 at the loading station 511 to the battery cell carrier 300 at the loading transfer device 20a, and the loading / unloading device 600 corresponding to the unloading station 512 is used to transport the battery cells in the battery cell carrier 300 at the unloading transfer device 20b to the battery cell transfer tray 700 at the unloading station 512.

[0068] Figure 3 is a partial enlarged view of point S1 in Figure 1. Referring to Figure 3, in some optional embodiments, the loading / unloading device 600 includes a transport gripper 610 and a gripper track 620, which extends along the X direction and spans the loading / unloading station 510 and the transfer device 200. The transport gripper 610 is movably connected to the gripper track 620 and is capable of moving along the gripper track 620.

[0069] In this embodiment, the transport gripper 610 is used to grip the battery cell. In some optional embodiments, it grips the tabs at both ends of the battery cell and can move back and forth along the gripper track 620 between the location of the loading / unloading station 510 and the location of the transfer device 200, so as to place the battery cell in the battery cell carrier 300 in the transfer device 200 or the battery cell transfer tray 700 located at the loading / unloading station 510.

[0070] In practical applications, the handling gripper 610 includes multiple grippers 611 and multiple linear modules. The multiple grippers 611 work together to grasp multiple battery cells at once, while the multiple linear modules enable the grippers 611 to rise and fall, and allow adjustment of the Y-axis and X-axis spacing between the grippers 611. Controlling the Y-axis spacing between the grippers 611 allows for adaptation to battery cells of different lengths, and controlling the X-axis spacing between the gripped battery cells allows for adjustment of the X-axis spacing between the multiple battery cells.

[0071] It should be noted that the linear module here can be, for example, a linear module formed by a transmission mechanism such as a guide rail slider, a ball screw and a motor, or a linear motor, an electric push rod 221, a cylinder, etc.

[0072] In the embodiment shown in Figure 1, the number of gripper tracks 620 is two, arranged parallel and spaced apart in the Y direction, i.e., a double-track scheme is adopted to ensure that the transport gripper 610 translates in the X direction. Furthermore, the transport gripper 610 is driven along the gripper tracks 620 by a gear and rack transmission mechanism in conjunction with a motor. However, this is not limited to a gear and rack transmission mechanism; for example, a belt drive mechanism, a ball screw in conjunction with a motor, or even a linear motor can be used directly.

[0073] In some alternative embodiments, the transplanting device further includes a cell clamp 400, which is spaced apart from the transfer device 200 in the Y direction. The cell carrier 300 is placed on or detached from the cell clamp 400 by the overhead crane device 100.

[0074] In this embodiment, the cell clamp 400 is used to assist in cell testing. Specifically, the cell clamp 400 can apply pressure to the cell inside the cell carrier 300 to cooperate with the testing device to test the cell.

[0075] Since the cell clamp 400 and the cell carrier 300 are arranged at intervals in the Y direction, the overhead crane device 100 can switch the cell carrier 300 between the transfer device 200 and the cell clamp 400. The location of the transfer device 200 is the transfer station, and the location of the cell clamp 400 is the inspection station.

[0076] To better understand this solution, the following is a brief description of the battery cell handling process in the battery cell charging and discharging equipment shown in Figure 1.

[0077] First, incoming materials from the logistics line 500 stop at the loading station 511, where a battery cell transfer pallet 700 loaded with battery cells is located. The loading / unloading device 600 then moves the battery cell transfer pallet 700 to the battery cell support module 320 within the battery cell carrier 300 at the loading transfer device 20a, until the number of battery cells in the battery cell carrier 300 reaches the set quantity. Understandably, during this process, the battery cell support module 320 is in an unfolded state, allowing the loading / unloading device 600 to place the battery cells from top to bottom.

[0078] Next, the transport crane 120 in the overhead crane device 100 moves to a position above the loading transfer device 20a. The transport crane 120, in conjunction with the lifting frame 310, lifts the entire cell carrier 300. After confirming that the cell carrier 300 has detached from the loading transfer device 20a, the cell support module 320 switches to a retracted state. The cell carrier 300 is moved along the Y direction above the cell clamp 400. The cell support module 320 then switches back to an extended state and places the cell carrier 300 into the cell clamp 400. Understandably, during this process, the retracted state of the cell support module 320 secures the loaded cell, reducing the risk of cell swaying during transport.

[0079] After the battery cells in the battery cell carrier 300 are inspected, the battery cell support module 320 is in the unfolded state. The battery cell carrier 300 is lifted by the overhead crane 120. After confirming that it is detached from the battery cell clamp 400, the battery cell support module 320 switches to the retracted state. The battery cell carrier 300 moves along the Y direction above the location of the unloading transfer device 20b and is placed on the unloading transfer device 20b. After confirming that the battery cell carrier 300 is placed on the unloading transfer device 20b, the battery cell support module 320 switches to the unfolded state again. With the battery cell support module 320 in the unfolded state, the unloading device 600 can remove the battery cells from the battery cell support module 320.

[0080] Next, the battery cells in the battery cell carrier 300 at the unloading transfer device 20b are transported to the battery cell transfer tray 700 at the unloading station 512 by the loading and unloading device 600. After the battery cell transfer tray 700 is full of battery cells, the logistics line 500 can move the battery cell transfer tray 700 out of the unloading station 512, thus forming a closed battery cell charge and discharge testing production line to realize batch testing of battery cells.

[0081] As can be seen from the above, the battery cell charging and discharging equipment equipped with the transplanting equipment provided in this application can transport the battery cells between the transfer device 200 and the battery cell clamp 400 by means of the overhead crane device 100 and the battery cell carrier 300, which can greatly reduce the risk of damaging the battery cells during the transportation process.

[0082] Figure 4 is a schematic diagram of the cell carrier 300 in Figure 2. Referring to Figure 4, in some optional embodiments, the cell support module 320 includes a plurality of cell support plate assemblies 321 and at least one cell support film 322;

[0083] Multiple cell support plate groups 321 are arranged along the X direction. The two sides of the cell support film 322 in the X direction are detachably connected to the two cell support plate groups 321 respectively. The cell support film 322 has a downwardly extending concave shape between two adjacent cell support plate groups 321, and the concave shape forms the cell placement area P.

[0084] In this embodiment, the cell support module 320 includes at least a plurality of cell support plate groups 321 and at least one cell support film 322. The cell support film 322 is a soft thin film material, which cooperates with the plurality of cell support plate groups 321 and forms a downwardly extending concave shape between two adjacent cell support plate groups 321. A cell placement area P that can place the cell is formed at the concave shape.

[0085] In one optional embodiment, there is one cell support film 322. The length of the cell support film 322 in the X direction is longer than the X-direction distance between the two outermost cells in the X direction among the multiple cell support plate groups 321. Thus, after the cell support film 322 is installed on the multiple cell support plate groups 321, a portion of the cell support film 322 can extend downward from between two adjacent cell support plate groups 321 to form a concave shape due to gravity.

[0086] In this embodiment, the cell support film 322 is detachably connected to the two outermost cell support plate assemblies 321. This detachable connection between the cell support film 322 and the cell support plate assemblies 321 facilitates the replacement of damaged cell support films 322. However, in this embodiment, the entire cell support film 322 needs to be replaced, resulting in relatively high costs.

[0087] In another alternative embodiment, there are multiple cell support films 322, and a cell support film 322 is provided between any two adjacent cell support plate groups 321. The X-direction length of each cell support film 322 is greater than the X-direction spacing between two adjacent cell support plate groups 321. In this way, the cell support module 320 extends downward between two adjacent cell support plate groups 321 due to gravity to form a concave shape.

[0088] In this embodiment, the X-direction sides of the cell support film 322 are detachably connected to two adjacent cell support plate groups 321, and the X-direction length of the cell support film 322 is relatively short, thus the replacement cost is relatively low.

[0089] In specific applications, the cell support film 322 can be detachably connected to the cell support plate assembly 321 through components such as magnetic clasps or snap fasteners, but it is not limited to this.

[0090] In some alternative embodiments, the cell support plate assembly 321 includes sliding bearing seats 3211 located on both sides in the Y direction, and the sliding bearing seats 3211 on both sides slide in engagement with the first guide rods 312 on both sides.

[0091] In this embodiment, the sliding bearing seat 3211 in the cell support plate assembly 321 is slidably connected to the first guide rod 312, so that the cell support plate assembly 321 can move along the first guide rod 312.

[0092] For the fixed cell support plate assembly 321b, a limiting ring is provided on the first guide rod 312 to limit and fix the sliding bearing seat 3211 in the fixed cell support plate assembly 321b, so that the fixed cell support plate assembly 321b cannot move.

[0093] In addition, the chain 323 passes through the sliding bearing seat 3211 in each cell support plate group 321 to connect each cell support plate group 321 in sequence.

[0094] Figure 5 is a partial enlarged view of point S3 in Figure 4. Referring to Figure 5, in some optional embodiments, the hoisting frame 310 is provided with a first guide rod 312 extending along the X direction. The first guide rod 312 is located on both sides of the hoisting frame 310 in the Y direction, and each cell support plate assembly 321 is connected to the first guide rod 312 on both sides.

[0095] The cell support module 320 also includes a chain 323, which is disposed on both sides of the multiple cell support plate groups 321 in the Y direction and connects the multiple cell support plate groups 321 sequentially in the X direction.

[0096] In this embodiment, the hoisting frame 310 has first guide rods 312 on both sides of the Y direction, and the first guide rods 312 on both sides extend along the X direction. The two ends of the cell support plate assembly 321 in the Y direction are correspondingly connected to the first guide rods 312 on both sides of the Y direction.

[0097] Optionally, the cell support module 320 also has chains 323 disposed at both ends of the cell support plate group 321 in the Y direction, and the cell support plate group 321 is connected sequentially in the X direction by the chains 323, that is, multiple cell support plate groups 321 are connected in series.

[0098] In practical applications, at least a portion of the cell support plate assembly 321 is movably connected to the first guide rods 312 on both sides, meaning that a portion of the cell support plate assembly 321 can move along the first guide rods 312. Thus, by simply driving a portion of the cell support plate assembly 321 to move, the remaining movable cell support plate assembly 321 can be moved together to achieve state switching.

[0099] Please refer to Figure 4. In an optional embodiment, among the multiple cell support plate groups 321, the two outermost ones in the X direction are the active cell support plate group 321a and the fixed cell support plate group 321b, respectively.

[0100] The fixed cell support plate assembly 321b is fixedly connected to the first guide rod 312, and the remaining cell support plate assembly 321 is movably connected to the first guide rod 312 and can move relative to the hoisting frame 310 in the X direction.

[0101] The overhead crane 120 is configured to connect to the active cell support plate group 321a and drive all the movable cell support plate groups 321a to move in the X direction to switch between the unfolded state and the retracted state.

[0102] In this embodiment, except for the fixed cell support plate group 321b which cannot move along the first guide rod 312, all other cell support plate groups 321 can move along the first guide rod 312. Among the movable cell support plate groups 321, one is the active cell support plate group 321a. The active cell support plate group 321a and the fixed cell support plate group 321b are the two outermost ones in the X direction among the multiple cell support plate groups 321. The cell support plate group 321 that can move between the active cell support plate group 321a and the fixed cell support plate group 321b is the follower cell support plate group 321c.

[0103] As described above, multiple cell support plate assemblies 321 are connected sequentially via chains 323. In specific applications, the active cell support plate assembly 321a is moved by the overhead crane 120, and the active cell support plate assembly 321a drives the follower cell support plate assembly 321c to move together in the X direction, thereby enabling the cell support film 322 located between two adjacent cell support plate assemblies 321 to expand and contract, thus achieving the purpose of switching the cell support module 320 between the expanded and contracted states.

[0104] Referring to Figure 5, in the unfolded state, the cell placement area P formed by the cell support film 322 has a shape that is wider at the top and narrower at the bottom, which facilitates the insertion of the cell from top to bottom. During the process of switching from the unfolded state to the retracted state, as the active cell support plate group 321a moves along the X direction toward the fixed cell support plate group 321b, the distance between each cell support plate group 321 decreases until the side walls of any two adjacent cell support plate groups 321 are in contact with each other. Correspondingly, the cell is clamped and fixed by the cell support film 322 and kept vertical. At this time, the cell support module 320 is in the retracted state. In the retracted state, the cell carrier 300 can reduce the risk of cell shaking.

[0105] Figure 6 is a schematic diagram of the overhead crane 120 in Figure 2. Figure 7 is a partial enlarged view of point S2 in Figure 2. Referring to Figures 2, 6, and 7, in some optional embodiments, the overhead crane 120 includes an X-axis adjustment module 122, which is used to adjust the cell support module 320 in the X-axis to switch the state of the cell support module 320.

[0106] In this embodiment, the overhead crane 120 has at least an X-axis adjustment module 122, which provides X-axis freedom of movement to drive the movement of some of the component modules in the cell support module 320, thereby switching the cell support module 320 between an extended state and a retracted state.

[0107] In practical applications, the X-axis adjustment module 122 can cooperate with the active cell support plate group 321a to drive the active cell support plate group 321a to move in the X-axis, thereby driving the follower cell support plate group 321c to move in the X-axis together to achieve the purpose of switching states.

[0108] In the embodiment shown in Figure 7, the X-axis adjustment module 122 has a downward-opening slot C, and the active cell support plate assembly 321a is provided with an upward-protruding lever 324. The lever 324 can be embedded in the slot C, so that the X-axis adjustment module 122 can connect with the lever 324 on the active cell support plate assembly 321a, thereby driving the active cell support plate assembly 321a.

[0109] Figure 8 is a schematic diagram of an X-axis adjustment module 122 according to one embodiment of this application. Referring to Figure 8, the X-axis adjustment module 122 includes an X-axis adjustment block structure 1221 and an X-axis telescopic mechanism 1222. The X-axis adjustment block structure 1221 is connected to the X-axis telescopic mechanism 1222 and is configured to move along the X-axis under the drive of the X-axis telescopic mechanism 1222.

[0110] In this embodiment, the X-axis adjustment module 122 includes at least an X-axis adjustment block structure 1221 and an X-axis telescopic mechanism 1222. The X-axis adjustment block structure 1221 is used to cooperate with the active cell support plate group 321a in the cell support module 320. The X-axis telescopic mechanism 1222 is used to move the X-axis adjustment block structure 1221 in the X-axis, thereby driving the active cell support plate group 321a to move in the X-axis to switch the state of the cell support module 320.

[0111] In the embodiment shown in Figure 8, the slot C is located in the X-direction adjustment block structure 1221. When the push block 324 on the active cell support plate group 321a is embedded in the slot C, the X-direction adjustment block structure 1221 can be connected to the push block 324.

[0112] The X-direction telescopic mechanism 1222 in the embodiment shown in Figure 8 is a telescopic mechanism formed by a ball screw and a motor. Of course, it is not limited to this. For example, an electric push rod 221, a cylinder, a hydraulic cylinder, etc. can be used to drive the X-direction adjusting block structure 1221 to move in the X direction.

[0113] Figure 9 is a partial enlarged view of S6 in Figure 4. Referring to Figure 12, in some optional embodiments, the hoisting frame 31010 is provided with a clamping plate 315 on the side near the active cell support plate assembly 321a, and the active cell support plate assembly 321a is provided with positioning beads 325.

[0114] In the unfolded state, the positioning plate 315 engages with the positioning bead 325. In the retracted state, the positioning plate 315 disengages from the positioning bead 325.

[0115] It should be understood that during the switching process of the cell support module 320, the position of the positioning bead 325 changes with the movement of the active cell support plate assembly 321a. When the cell support module 320 is in the unfolded state, the positioning bead 325 is positioned at and connected to the positioning plate 315. This connection between the positioning bead 325 and the positioning plate 315 maintains the unfolded state of the cell support module 320, facilitating cell removal and removal. Furthermore, during the switching process from the unfolded state to the retracted state, the positioning bead 325 disengages from the positioning plate 315.

[0116] In this embodiment, positioning beads 325 are provided on both sides of the active cell support plate assembly 321a in the Y direction. Correspondingly, clamping plates 315 are also provided on both sides of the hoisting frame 310 in the Y direction. The clamping plates 315 on both sides are connected to the positioning beads 325 on both sides to ensure the stability of maintaining the unfolded state.

[0117] In practical applications, the card plate 315 is provided with a notch to cooperate with the positioning bead 325. The positioning bead 325 can rotate to facilitate contact with or disengagement from the card plate 315.

[0118] Referring to Figures 2 and 4, in some optional embodiments, the overhead crane 120 includes crane support plates 121 disposed on both sides in the Y direction. The crane support plates 121 on both sides extend along the X direction and are configured to be able to move closer to or further away from each other in the Y direction.

[0119] The hoisting frame 310 is provided with multiple hoisting trays 311. When the overhead crane support plates 121 on both sides are far apart from each other, the X-direction end of the overhead crane support plate 121 can connect with the corresponding hoisting tray 311.

[0120] In this embodiment, the overhead crane 120, through the crane support plates 121 arranged on both sides of the Y direction and capable of retracting and extending in the Y direction, cooperates with the lifting support plates 311 in the lifting frame 310, thereby enabling it to lift the entire battery cell carrier 300.

[0121] Specifically, when the overhead crane support plates 121 on both sides move away from each other in the Y direction, that is, when they are unfolded in the Y direction, the X-direction ends of the overhead crane support plates 121 on both sides can cooperate with the corresponding lifting support plates 311 in the lifting frame 310. This cooperation method can be overlapping or snap-fit ​​connection, etc.

[0122] When the overhead crane support plates 121 on both sides approach each other in the Y direction, that is, when they retract in the Y direction, the X-direction ends of the overhead crane support plates 121 on both sides can disengage from the corresponding lifting support plates 311 in the lifting frame 310.

[0123] Thus, by controlling the extension and retraction of the overhead crane support plates 121 on both sides, the transport crane 120 can be connected to or disconnected from the battery cell carrier 300.

[0124] It should be understood that the battery cell carrier 300 can be hoisted when the overhead crane support plates 121 on both sides are extended. After the battery cell carrier 300 is placed in the transfer device 200 or the battery cell clamp 400, the overhead crane support plates 121 on both sides can be switched from extended to retracted, so that the transport crane 120 can be disengaged from the battery cell carrier 300.

[0125] Referring to Figures 2 to 4, the hoisting frame 310 can be a rectangular frame structure assembled from multiple beams, wherein the hoisting support plate 311 is located at the corner of the hoisting frame 310. The X-direction length of the overhead crane support plate 121 is shorter than the X-direction length of the enclosed area of ​​the hoisting frame 310, and the hoisting support plate 311 is located on the inner side of the corner of the hoisting frame 310.

[0126] Therefore, when the overhead crane support plates 121 on both sides are retracted, they can enter the area enclosed by the hoisting frame 310 along the Z direction. After the relative positions of the overhead crane support plates 121 and the hoisting frame 310 in the Z direction are appropriate, the overhead crane support plates 121 on both sides can be unfolded until the two ends of the overhead crane support plate 121 on one side in the X direction cooperate with the hoisting support plates 311 on both sides of the hoisting frame 310 in the Y direction.

[0127] Figure 10 is a partial enlarged view of S4 in Figure 4. Figure 11 is a partial enlarged view of S5 in Figure 6. Referring to Figures 10 and 11, in some optional embodiments, the lifting pallet 311 is provided with a downwardly extending positioning pin 313, and the X-direction end plate segment of the overhead crane support plate 121 is provided with a positioning pin hole H1. When the two sides of the overhead crane support plates 121 are away from each other, the positioning pin 313 and the positioning pin hole H1 can be aligned in the Z-direction.

[0128] Thus, by raising and lowering the overhead crane support plate 121, the two sides of the overhead crane support plate 121 can be connected to or disconnected from the hoisting support plate 311.

[0129] Optionally, the overhead crane support plate 121 is also equipped with a hoisting positioning detection switch 1211, which is located at the X-direction end of the overhead crane support plate 121. The hoisting support plate 311 is equipped with a hoisting positioning baffle 314. After the overhead crane support plates 121 on both sides are moved into position, the hoisting positioning baffle 314 can trigger the hoisting positioning detection switch 1211 to send a switching signal to confirm that the overhead crane support plate 121 is in the required hoisting position.

[0130] It should be noted that when the Z-axis position of the overhead crane support plate 121 meets the height requirements for hoisting and coordination with the hoisting frame 310, the slot C in the X-axis adjustment module 122 can accommodate the lever 324 on the active cell support plate group 321a.

[0131] As mentioned above, the overhead crane support plate 121 has a Z-axis lifting freedom, which enables it to work with the hoisting frame 310 to lift the entire cell carrier 300. Furthermore, when the overhead crane support plate 121 reaches the required height for hoisting and engagement with the cell carrier 300 in the Z-axis direction, the X-axis adjustment module 122 is precisely connected to the active cell support plate assembly 321a, indicating that the X-axis adjustment module 122 also has a Z-axis lifting freedom. In other words, the overhead crane support plate 121 and the X-axis adjustment module 122 are configured to be able to lift in the Z-axis direction.

[0132] Referring to Figure 2, in some optional embodiments, the overhead crane 120 further includes a lifting frame 123 and a traveling frame 124. The traveling frame 124 is movably connected to the crane track 110 and is capable of moving along the crane track 110. The lifting frame 123 is movably connected to the traveling frame 124 and is capable of moving up and down relative to the traveling frame 124 in the Z direction.

[0133] The overhead crane support plate 121 and the X-axis adjustment module 122 are both mounted on the lifting frame 123 so that they can rise and fall together with the lifting frame 123. In this way, the overhead crane support plate 121 and the X-axis adjustment module 122 have Z-axis lifting freedom.

[0134] In an optional embodiment, the lifting frame 123 includes an upper plate 1231, a lower plate 1232, a lifting screw 1233, and multiple second guide rods 1234. The upper plate 1231 and the lower plate 1232 are spaced apart in the Z direction, and the multiple second guide rods 1234 are connected between the upper plate 1231 and the lower plate 1232 and are slidably connected to the traveling frame 124.

[0135] Referring to Figure 2, optionally, the overhead crane 120 also includes a lifting drive mechanism 125, which is mounted on the upper plate 1231 and is used to drive the lifting screw 1233 to rotate, so that the lifting frame 123 can move up and down relative to the traveling frame 124 in the Z direction. That is, the rotary motion is converted into the Z-direction linear motion of the lifting frame 123 by the lifting screw 1233.

[0136] In the embodiment shown in Figure 2, the lifting drive mechanism 125 uses a motor and a synchronous belt to drive the lifting screw 1233 to rotate. Of course, it is not limited to this. For example, a motor and a gear set can also be used to drive the lifting screw 1233 to rotate.

[0137] Please refer to Figure 6. In an optional embodiment, the overhead crane 120 further includes a Y-direction retraction mechanism 126. The Y-direction retraction mechanism 126 is disposed on the lower plate 1232. The crane support plates 121 on both sides of the Y direction are movably connected to the lower plate 1232 and the Y-direction retraction mechanism 126. The crane support plates 121 on both sides of the Y direction can move closer to or further away from each other under the drive of the Y-direction retraction mechanism 126.

[0138] It should be noted that, in order to ensure the stable translation of the overhead crane support plate 121 along the Y direction, the overhead crane support plate 121 and the lower plate 1232 are connected by a guide rail slider transmission mechanism.

[0139] In the embodiment shown in Figure 6, the Y-axis retraction mechanism 126 is a retraction mechanism based on a bidirectional lead screw. Specifically, the bidirectional lead screw is driven by a motor in conjunction with a synchronous belt, and the overhead crane support plates 121 on both sides of the Y-axis are respectively connected to different helical segments of the bidirectional lead screw. Of course, the Y-axis retraction mechanism 126 is not limited to this; for example, it can also be a combination of two linear motors, a combination of two cylinders, etc.

[0140] In some alternative embodiments, the transport crane 120 further includes a traveling mechanism 127 disposed on the traveling frame 124 and used to cooperate with the crane track 110 to allow the transport crane 120 to move along the crane track 110.

[0141] In the embodiment shown in Figure 6, a rack and pinion transmission mechanism is formed between the traveling mechanism 127 and the overhead crane track 110. This mechanism uses a motor, a synchronous belt, and a drive shaft to drive the gears on both sides of the Y-direction, thereby enabling movement along the overhead crane track 110 on both sides of the Y-direction. Of course, the traveling mechanism 127 is not limited to this; for example, it could be a linear motor installed on both sides of the traveling frame 124 in the Y-direction.

[0142] Figure 12 is a schematic diagram of the transfer device 200 in Figure 1. Figure 13 is a schematic diagram of the guide clamp mechanism 210 in Figure 12. Referring to Figures 12 and 13, in some optional embodiments, the transfer device 200 includes guide clamp mechanisms 210 disposed on both sides in the Y direction. The guide clamp mechanism 210 includes a clamp gap adjusting plate assembly 211 and a plurality of guide clamps 212. The clamp gap adjusting plate assembly 211 extends along the X direction, and the plurality of guide clamps 212 are spaced apart from the clamp gap adjusting plate assembly 211 along the X direction.

[0143] The battery cells loaded in the battery cell support module 320 can be placed between two adjacent guide clamps 212. The clamp gap adjustment plate group 211 is configured to synchronously adjust the gap between multiple guide clamps 212 to accommodate battery cells of different thicknesses.

[0144] In this embodiment, the guide clamping mechanisms 210 on both sides of the Y direction in the transfer device 200 are used to limit the battery cells placed in the battery cell carrier 300 at the transfer device 200. Specifically, the guide clamping mechanism 210 includes at least a clamping gap adjusting plate group 211 and a plurality of guide clamps 212. The clamping gap adjusting plate group 211 extends along the X direction, and each guide clamp 212 is installed at intervals along the X direction on the clamping gap adjusting plate group 211.

[0145] Specifically, since the multiple guide clips 212 are spaced apart, a space for accommodating the battery cell is formed between two adjacent guide clips 212. The guide clips 212 on both sides separate the adjacent battery cells, reducing the risk of battery cell collision damage.

[0146] In summary, the battery cell is placed in the battery cell support film 322 between two adjacent battery cell support plate groups 321. In other words, each battery cell support film 322 between two adjacent battery cell support plate groups 321 can be inserted into the gaps formed by multiple guide clips 212. That is, the battery cell support film 322 is first limited in the X direction, and then the battery cell is placed from top to bottom in the battery cell support film 322 that has been limited in the X direction.

[0147] In addition, the clamp gap adjustment plate group 211 can synchronously adjust the gap between each guide clamp 212 to limit the movement of battery cells of different thicknesses, ensuring that the transfer device 200 has good versatility.

[0148] Figure 14 is a partial enlarged view of S7 in Figure 13. Referring to Figure 14, in some optional embodiments, the guide clamp 212 includes a fixed clamping plate 2121 and a movable clamping plate 2122, which are spaced apart in the X direction.

[0149] The clamp gap adjusting plate assembly 211 includes an upper adjusting plate 2111 and a lower adjusting plate 2112, which are spliced ​​together in the Z direction. The fixed clamping plate 2121 in each guide clamp 212 is connected to the upper adjusting plate 2111, and the movable clamping plate 2122 in each guide clamp 212 is connected to the lower adjusting plate 2112.

[0150] The lower adjusting plate 2112 can move relative to the upper adjusting plate 2111 in the X direction to synchronously adjust the distance between the movable clamp 2122 of one of the two adjacent guide clamps 212 and the fixed clamp 2121 of the other.

[0151] In this embodiment, the guide clamp 212 consists of a pair of clamping plates, one of which is a fixed clamping plate 2121 and the other is a movable clamping plate 2122. The clamp gap adjusting plate assembly 211 consists of an upper adjusting plate 2111 and a lower adjusting plate 2112 stacked from top to bottom.

[0152] In each guide clamp 212, the fixed clamping plate 2121 is fixedly mounted on the upper adjusting plate 2111, and the movable clamping plate 2122 is fixedly mounted on the lower adjusting plate 2112. It should be noted that for any two adjacent guide clamps 212, the movable clamping plate 2122 of one is closer to the fixed clamping plate 2121 of the other. The lower adjusting plate 2112 can move along the X-direction, thereby moving the fixed clamping plate 2121. This allows adjustment of the X-direction distance between two adjacent guide clamps 212 to accommodate battery cells of different thicknesses.

[0153] In the illustrated embodiment, the upper adjusting plate 2111 has an elongated through hole H1, and each movable clamping plate 2122 corresponds to two elongated through holes H1. The elongated through holes H1 extend along the X direction and are fitted with studs 213. The movable clamping plate 2122 engages with the lower adjusting plate 2112 via the studs 213. It should be understood that when the lower adjusting plate 2112 is moved, the studs 213 can move within the elongated through holes H1. Of course, the X-direction length of the elongated through holes H1 also limits the range of movement of the movable clamping plate 2122. It should be noted that the connection method of the lower adjusting plate 2112 is not limited to the illustrated embodiment.

[0154] Figure 15 is a schematic diagram of the alignment mechanism 220 in Figure 12. Referring to Figure 15, in some optional embodiments, the transfer device 200 further includes a cell alignment mechanism 220, which is located on the Y-direction outer side of the guide clamp mechanism 210.

[0155] The cell alignment mechanism 220 includes a push rod 221 extending along the X direction, which is configured to move along the Y direction toward the guide clamp mechanism 210 to align the ends of a plurality of cells located between the guide clamps 212 in the X direction.

[0156] It should be understood that the loading / unloading device 600 can only remove and discharge cells from the cell carrier 300 when the cell carrier 300 is placed in the transfer device 200. In this embodiment, the cell alignment mechanism 220 aligns the cells in the cell carrier 300 in the X direction, which facilitates the cell removal and handling processes.

[0157] Specifically, the cell alignment mechanism 220 is located outside the guide clamp mechanism 210 in the Y direction and has a push rod 221 capable of reciprocating in the Y direction. Thus, the push rod 221 can move towards the guide clamp mechanism 210 and abut against one end of one of the multiple cells located between the guide clamps 212, thereby aligning the Y ends of the multiple cells in the X direction. Here, X-direction alignment refers to the alignment of the Y ends of the cells in the X direction.

[0158] It should be noted that since the equipment provided in the application is mainly adapted to airless battery cells, the gripper 611 in the loading and unloading device 600 grips the tabs on both sides of the battery cell. The two ends of the battery cell in the Y direction are the tabs. Aligning the tabs makes it easier for the loading and unloading device 600 to pick up and put down the battery cells.

[0159] In practical applications, the push rod 221 can be provided with a degree of freedom of movement by a cylinder, hydraulic cylinder, electric push rod 221, etc., so that the push rod 221 can reciprocate in the Y direction.

[0160] In an optional embodiment, the transfer device 200 further includes a transfer support frame 230, which is provided with a cell carrier 300 positioning structure. The cell carrier 300 positioning structure is used to determine the placement position of the cell carrier 300 at the transfer device 200 so that each cell loaded in the cell carrier 300 is located between two adjacent guide clips 212.

[0161] In this embodiment, the transfer device 200 also includes a transfer support frame 230, which is a frame structure spliced ​​from multiple beams and plates. The guide clamping mechanism 210 is connected to the transfer support frame 230 and is at least partially located within the transfer support frame 230.

[0162] In the embodiment shown in Figure 12, the positioning structure of the battery cell carrier 300 includes limiting support blocks 231 located at the four corners of the transfer support frame 230, and the limiting support blocks 231 form grooves with top openings. Referring to Figure 4, the four corners of the hoisting frame 310 are provided with limiting protrusions 316. When the battery cell carrier 300 is placed on the transfer device 200, the limiting protrusions 316 are embedded in the grooves on the limiting support blocks 231.

[0163] In the diagram, the four limiting protrusions 316 on the lifting frame 310 are the X-direction ends of the first guide rods 312 on both sides of the Y-direction, that is, the X-direction ends of the first guide rods 312 extend outside the lifting frame 310 to form the limiting protrusions 316. Of course, protrusions can also be directly installed on the lifting frame 310 as limiting protrusions 316. The design can be customized according to requirements.

[0164] Optionally, the positioning mechanism of the battery cell carrier 300 also includes a positioning detection switch 232 arranged diagonally. When the battery cell carrier 300 is in an accurate position, the hoisting frame 310 is exactly abutting against the positioning detection switch 232 and sends a switching signal to confirm that the battery cell carrier 300 is in an accurate position.

[0165] Of course, the positioning structure of the battery cell carrier 300 is not limited to the cooperation between the limiting support block 231 and the limiting protrusion 316. For example, it can also be the cooperation between the positioning pin and the pin hole.

[0166] Figure 16 is a partial enlarged view of S8 in Figure 1. Referring to Figure 16, in some optional embodiments, the cell clamp 400 is a cell restraint clamp without the cell support film 322 and is provided with a positioning block 410 to define the placement position of the cell carrier 300.

[0167] In this embodiment, the battery cell clamp 400 has a similar structure to the battery cell carrier 300. The battery cell clamp 400 has a clamp frame 420 and a pressure plate module 430 connected to the battery cell clamp 400 frame 420. The pressure plate module 430 is configured to move in the X direction for retraction and expansion. The pressure plate module 430 includes multiple pressure plates that can move in the X direction. There is no battery cell support film 322 between two adjacent pressure plates.

[0168] That is, the pressure plate module 430 does not have a cell support film 322 compared to the cell support module 320, and is thus a cell restraint fixture without a cell support film 322. Furthermore, when the pressure plates in the pressure plate module 430 come close to each other (i.e., contract), they can apply pressure to the cell in preparation for the subsequent charging and testing process.

[0169] The battery cell clamp 400 has a positioning block 410. The positioning block 410 has an upward-opening groove and is located at the four corners of the clamp frame 420 (only one corner positioning block 410 is shown in Figure 16). When the battery cell carrier 300 is placed in the battery cell clamp 400, the limiting protrusion 316 at the hoisting frame 310 is precisely embedded in the groove of the positioning block 410 to achieve the positioning purpose.

[0170] In summary, the transplanting equipment and battery cell charging / discharging equipment provided in this application have at least the following beneficial effects:

[0171] The battery cell charging and discharging equipment provided in this application includes a transfer device, a logistics line 500, and a loading and unloading device 600. Among them, the transfer device includes at least an overhead crane device 100, a transfer device 200, and a battery cell carrier 300. The main function of the transfer device is to realize the transfer and transportation of battery cells and to switch battery cells between different workstations.

[0172] Specifically, the transfer device 200 is located below the overhead crane device 100, the battery cell carrier 300 is used to load the battery cells and can be placed in the transfer device 200, and the overhead crane device 100 can lift and move the battery cell carrier 300 to move the battery cells in the battery cell carrier 300 to different work positions.

[0173] The overhead crane device 100 includes at least an overhead crane track 110 and a transport crane 120. The transport crane 120 is movably connected to the overhead crane track 110 and can move along the overhead crane track 110, that is, the transport crane 120 has a Y-direction degree of freedom of movement.

[0174] In addition, the cell carrier 300 includes at least a lifting frame 310 and a cell support module 320. The cell support module 320 is used to load the cell, and the lifting frame 310 can cooperate with the overhead crane 120 to lift the entire cell carrier 300. Moreover, the cell support module 320 can switch between an extended state and a retracted state. In the extended state, the loading and unloading device 600 can place the cell into the cell support module 320; in the retracted state, the cell placed in the cell support module 320 can be fixed, reducing the risk of damage to the cell due to shaking during transportation.

[0175] In this way, the overhead crane 120 can lift the battery cell carrier 300, which can place the battery cell carrier 300 in the transfer device 200 or lift the battery cell carrier 300 out of the transfer device 200. It can also move the battery cell carrier 300 and all the battery cells together along the Y direction, thereby moving and placing the battery cells at different workstations.

[0176] As can be seen, in the transplanting equipment provided in this application, the overhead crane device 100, in conjunction with the cell carrier 300, indirectly transports the battery cells, and the transfer device 200 serves as a transfer station for the cell carrier 300 during the battery cell transport process. In this application, the overhead crane device 100 does not directly act on the battery cells to achieve transport; instead, it loads the battery cells onto the cell carrier 300, and then the overhead crane device 100 moves the cell carrier 300 to achieve the transfer of the battery cells.

[0177] The transfer of battery cells is achieved by adding an additional battery cell carrier 300 and cooperating with a newly designed overhead crane device 100. Due to the support and protection provided by the battery cell carrier 300, the stability during the handling process is ensured, which can greatly reduce the risk of damage to the battery cells during the handling process.

[0178] In the following embodiments of this application, the terms “X direction”, “Y direction” and “Z direction” are determined based on the Cartesian coordinate system constructed by the cell carrier 300b in the embodiments of this application. It should be noted that the Z direction is also the up and down direction.

[0179] Figure 17 is a schematic diagram of a cell carrier 300b according to one embodiment of this application. Figure 18 is a schematic diagram of the cell carrier 300b in Figure 17 from another perspective. Figure 19 is a partial enlarged view of point S1 in Figure 17. Referring to Figures 17 to 19, the cell carrier 300b includes a lifting frame 310b, a support module 320b, and an unfolding positioning structure 30b.

[0180] The lifting frame 310b has first guide rods 312b extending in the X direction on both sides in the Y direction. A support module 320b is connected to the first guide rods 312b on both sides and is configured to switch between an extended state and a retracted state. When the support module 320b is in the extended state, it is used to retrieve and discharge battery cells; when it is in the retracted state, it is used to fix the battery cells. An extension positioning structure 30b is provided on the lifting frame 310b and the support module 320b to limit the support module 320b to the extended state.

[0181] In this embodiment, the cell carrier 300b includes at least a hoisting frame 310b, a support module 320b, and an unfolding positioning structure 30b. The hoisting frame 310b is provided with a first guide rod 312b, which is located on both sides of the hoisting frame 310b in the Y direction.

[0182] The supporting module 320b is connected to the first guide rod 312b on the hoisting frame 310b. It should be noted that at least some of the components of the supporting module 320b are movably connected to the first guide rod 312b and can move along the first guide rod 312b, thereby realizing state switching.

[0183] Specifically, the support module 320b has an unfolded state and a retracted state. In the unfolded state, it can place or remove battery cells from the support module 320b. In the retracted state, it secures the battery cells to prevent them from shaking during handling, ensuring their safety during transportation. In other words, when the support module 320b is in the unfolded state, it can place or remove battery cells; when it is in the retracted state, it secures the battery cells to prevent them from shaking during handling, ensuring their safety during transportation.

[0184] Optionally, the deployment positioning structure 30b in the cell carrier 300b can keep the support module 320b in the deployed state, thereby ensuring that the support module 320b is in the deployed state during the cell removal and discharge process, improving the safety of the cell removal and discharge process, and reducing the risk of damaging the cell.

[0185] Referring to Figure 19, in an optional embodiment, the unfolding positioning structure 30b includes a positioning bead 31b and a positioning plate 32b. The positioning bead 31b is disposed on the supporting module 320b, and the positioning plate 32b is connected to the hoisting frame 310b.

[0186] In the unfolded state, the positioning plate 32b engages with the positioning bead 31b. In the retracted state, the positioning plate 32b disengages from the positioning bead 31b.

[0187] In this embodiment, the unfolding positioning structure 30b has at least a positioning bead 31b and a positioning plate 32b. The positioning bead 31b is fixedly installed on the supporting module 320b, and the positioning plate 32b is fixedly installed on the hoisting frame 310b.

[0188] It should be understood that the position of the positioning bead 31b changes during the switching process of the support module 320b. When the support module 320b is in the unfolded state, the positioning bead 31b is positioned in the location of the positioning plate 32b and is connected to the positioning plate 32b. This connection between the positioning bead 31b and the positioning plate 32b maintains the unfolded state of the support module 320b, facilitating the removal and removal of the discharge core. Conversely, during the switching process from the unfolded state to the retracted state, the positioning bead 31b disengages from the positioning plate 32b.

[0189] Figure 20 is a partial enlarged view of S4 in Figure 18. Referring to Figure 20, in some optional embodiments, the lifting frame 310b is rectangular and has multiple trays 311b, which are located at the corners of the lifting frame 310b and have downwardly extending positioning pins 313b.

[0190] In this embodiment, the hoisting frame 310b is a rectangular frame structure assembled from multiple beams, plates, etc. Each corner of the hoisting frame 310b is provided with a support plate 311b, and these support plates 311b are provided with positioning pins 313b. The positioning pins 313b can cooperate with the transfer device used to transport the battery cell carrier 300b.

[0191] That is, when the cell carrier 300b is transported by the transplanting device, the transplanting device can be connected to the pallet 311b to lift the entire cell carrier 300b. The positioning pin 313b on the pallet 311b ensures that the transplanting device is stably connected to the pallet 311b, reducing the risk of shaking during transportation.

[0192] Referring to Figures 17, 18, and 20, in the illustrated embodiment, there are four pallets 311b, located at the four corners of the lifting frame 310b. Secondly, regarding the number and position of the positioning pins 313b, in this illustrated case, at least two diagonally opposite pallets 311b must have positioning pins 313b to ensure the relative position of the battery cell carrier 300b and the transplanting device is fixed during lifting. Optionally, each pallet 311b may have at least one positioning pin 313b.

[0193] Additionally, the first guide rod 312b is located on both sides of the hoisting frame 310b in the Y direction and below the hoisting frame 310b. Referring to Figure 19, the positioning plate 32b is mounted on the support plate 311b.

[0194] Figure 21 is a partial enlarged view of S3 in Figure 17. Referring to Figure 21, in some optional embodiments, the support module 320b includes a plurality of support plate assemblies 321c and at least one support membrane 322b.

[0195] Multiple support plate groups 321c are arranged along the X direction and are all connected to the first guide rods 312b on both sides. The X-direction sides of the support membrane 322b are detachably connected to the side walls of two adjacent support plate groups 321c and bent to form a cell placement area P.

[0196] In this embodiment, the support module 320b includes at least a plurality of support plate groups 321c and at least one support film 322b. The support film 322b is detachably connected to the sidewalls of two adjacent support plate groups 321c. The support film 322b is a soft film material. The X-direction length of the support film 322b is longer than the X-direction spacing between two adjacent support plate groups 321c. Therefore, the support film 322b will bend and form a cell placement area P. The cell can be placed in the cell placement area P. The support film 322b can protect the cell.

[0197] In addition, the support film 322b is designed to be detachably connected to the support plate assembly 321c, which facilitates disassembly and replacement of the support film 322b.

[0198] It should be noted that in the embodiment shown in Figure 21, the support module 320b is in an unfolded state, and correspondingly, the support film 322b is bent into a V shape, that is, the cell placement area P is a V-shaped space, and the cell can be placed into the cell placement area P from top to bottom. Since the cell is not fixed, the cell will shake in the cell placement area P.

[0199] In an optional embodiment, the support module 320b further includes a connecting chain 323b. Among the plurality of support plate groups 321c, the two outermost ones in the X direction are the active support plate group 321d and the fixed support plate group 321e, respectively. The fixed support plate group 321e is fixedly connected to the first guide rods 312b on both sides, and the remaining support plate groups 321c are slidably connected to the first guide rods 312b on both sides.

[0200] Connecting chains 323b are disposed on both sides of the multiple support plate groups 321c in the Y direction and connect the multiple support plate groups 321c sequentially along the X direction. Positioning beads 31b in the unfolded positioning structure 30b are disposed on both sides of the active support plate group 321d in the Y direction.

[0201] In this embodiment, the connecting chains 323b on both sides of the Y direction connect multiple support plate groups 321c arranged along the X direction in series, and the connecting chains 323b on one side connect the Y-direction same-side ends of the multiple support plate groups 321c in sequence.

[0202] Of the multiple support plate assemblies 321c, the two outermost ones in the X direction, one serves as the fixed support plate assembly 321e and the other as the active support plate assembly 321d. Except for the fixed support plate assembly 321e, which is fixed to the first guide rod 312b, the remaining support plate assemblies 321c are all slidably connected to the first guide rod 312b. That is, except for the fixed support plate assembly 321e, the other support plate assemblies 321c can slide along the first guide rod 312b.

[0203] In other words, the active support plate assembly 321d can slide along the first guide rod 312b. In addition, the support plate assembly 321c located between the fixed support plate assembly 321e and the active support plate assembly 321d is the follower support plate assembly 321f, which can also move along the first guide rod 312b.

[0204] In a specific application, the transfer device used to transport the battery cell carrier 300b can drive the active support plate group 321d to move along the first guide rod 312b. Since multiple support plate groups 321c are connected by a connecting chain 323b, during the movement of the active support plate group 321d, each follower support plate group 321f will move along the first guide rod 312b via the connecting chain 323b, thereby realizing the switching of the state of the support module 320b.

[0205] Additionally, referring to Figure 19, the positioning beads 31b in the unfolded positioning structure 30b are installed on both sides of the active support plate assembly 321d in the Y direction. Correspondingly, the two support plates 311b in the hoisting frame 310b near the active support plate assembly 321d are provided with positioning plates 32b. When the active support plate assembly 321d moves to below the positioning plates 32b, the positioning plates 32b connect with the positioning beads 31b, at which point the support module 320b is in the unfolded state.

[0206] In the embodiment shown in Figure 19, the positioning plate 32b has a notch to engage with the positioning bead 31b. The positioning bead 31b is rotatable to facilitate engagement or disengagement from the positioning plate 32b. In practical applications, when the supporting module 320b is in the unfolded state, the connecting chain 323b is in the taut state.

[0207] In other words, in addition to limiting the position of the active support plate group 321d in the unfolded state through the unfolded positioning structure 30b, the position of the active support plate group 321d in the unfolded state can be further limited by the length of the connecting chain 323b.

[0208] Referring to Figure 19, in the unfolded state, the cell placement area P formed by the support film 322b has a shape that is wider at the top and narrower at the bottom, which facilitates the insertion of the cell from top to bottom. During the process of switching from the unfolded state to the retracted state, as the active support plate group 321d moves along the X direction toward the fixed support plate group 321e, the spacing between each support plate group 321c decreases until the side walls of any two adjacent support plate groups 321c are in contact with each other. Correspondingly, the cell is clamped and fixed by the support film 322b and kept vertical. At this time, the support module 320b is in the retracted state. In the retracted state, the cell carrier 300b can reduce the risk of cell shaking.

[0209] Figure 22 is a partial enlarged view of S2 in Figure 17. Referring to Figure 22, in some optional embodiments, the active support plate assembly 321d is provided with a toggle block 21a1, which is configured to protrude upwards and is used to assist in switching the state of the support module 320b.

[0210] In this embodiment, an upwardly protruding lever 21a1 is fixedly installed on the active support plate assembly 321d. In specific applications, the transfer device for transporting the battery cell carrier 300b drives the active support plate assembly 321d to move along the first guide rod 312b, i.e., in the X direction, by acting on the lever 21a1. Therefore, the lever 21a1 is used in conjunction with the transfer device to assist in switching the state of the support module 320b.

[0211] In an optional embodiment, the active support plate assembly 321d is provided with a status detection piece 21a2, which is configured to extend downward and is used to assist in confirming that the support module 320b is in the unfolded state.

[0212] In practical applications, the status detection piece 21a2 is used in conjunction with the detection switch. When the supporting module 320b is in the unfolded state, the status detection piece 21a2 is in the position of the detection switch, and the detection switch can send a switching signal to confirm that the supporting module 320b is in the unfolded state.

[0213] In other words, in this embodiment, hard limiting is achieved by unfolding the positioning structure 30b and the length of the connecting chain 323b, while soft limiting is achieved by the state detection piece 21a2 cooperating with the detection switch.

[0214] Figure 23 is a schematic diagram of a support plate assembly 321c provided according to one embodiment of this application. Referring to Figure 23, the support plate assembly 321c includes a connecting rod 211b and a slider structure 212b.

[0215] The slider structure 212b is connected to both ends of the connecting rod 211b in the Y direction. The slider structures 212b at both ends are correspondingly sleeved on the first guide rods 312b on both sides. The X-direction sides of the supporting membrane 322b are detachably connected to the side walls of the two adjacent connecting rods 211b.

[0216] In this embodiment, the support plate assembly 321c has at least a connecting rod 211b and a slider structure 212b. The slider structure 212b is installed at both ends of the connecting rod 211b in the Y direction. The slider structures 212b at both ends are correspondingly sleeved on the first guide rods 312b on both sides, so that the support plate assembly 321c is connected to the first guide rods 312b.

[0217] The supporting membrane 322b is detachably connected to the two adjacent supporting plate assemblies 321c by being detachably connected to the two adjacent connecting rods 211b.

[0218] It should be understood that the X-direction sides of the support membrane 322b can be installed on the sidewalls of the connecting rod 211b respectively. In the contracted state, the sidewalls of two adjacent connecting rods 211b are close to each other, so that the X-direction sides of the support membrane 322b are close to each other, thus closing the upper opening of the cell placement area P.

[0219] Optionally, the slider structure 212b includes a slider 2121b and a connecting chain mounting member 2122b. The connecting chain mounting member 2122b is connected to the Y-direction end of the slider 2121b away from the connecting rod 211b and is used to mount the connecting chain 323b. The slider 2121b is provided with a guide rod through hole H1, which is clearance-fitted with the first guide rod 312b.

[0220] In this embodiment, the slider structure 212b includes at least a slider 2121b and a connecting chain mounting member 2122b. The connecting chain mounting member 2122b is located at the Y-direction end of the slider 2121b away from the connecting rod 211b. The connecting chain 323b can pass through the connecting chain mounting members 2122b in multiple support plate groups 321c in sequence, thereby connecting multiple support plate groups 321c in sequence. Only the active support plate group 321d needs to be driven to drive each follower support plate group 321f to switch the state of the support module 320b.

[0221] It should be understood that, due to the clearance fit between the guide rod through hole H1 and the first guide rod 312b, the support plate assembly 321c can move along the first guide rod 312b, thus achieving a sliding fit between the support plate assembly 321c and the first guide rod 312b. It should be noted that for the fixed support plate assembly 321e, corresponding limiting rings are provided on both sides of the slider 2121b located on the first guide rod 312b. These limiting rings ensure that the fixed support plate assembly 321e cannot move relative to the first guide rod 312b.

[0222] Figure 24 is a schematic diagram of a support film 322b according to one embodiment of the present application. Referring to Figure 24, the support film 322b is provided with a plurality of sub-fasteners 221b, which are connected to both sides of the support film 322b in the X direction and spaced apart along the Y direction.

[0223] The connecting rod 211b is provided with multiple female buckles 213b, which are spaced apart along the Y direction and located on the side wall of the connecting rod 211b. The multiple female buckles 213b can be connected one-to-one with the multiple female buckles 221b to detachably connect the supporting film 322b to the connecting rod 211b.

[0224] In this embodiment, the supporting membrane 322b has multiple female buckles 221b arranged at intervals along the Y direction on both sides of the X direction, and the connecting rod 211b has multiple female buckles 213b arranged at intervals along the Y direction. The number of female buckles 221b and female buckles 213b are equal and they can be connected one by one.

[0225] In other words, in this embodiment, the supporting membrane 322b and the connecting rod 211b are detachably connected by a snap fastener 213b. The snap fastener 213b allows for quick and cost-effective detachable connection.

[0226] Another aspect of this application provides a cell carrier transfer device (not shown in the illustrations), which includes a transfer device (not shown in the illustrations) and the aforementioned cell carrier 300b. The transfer device can cooperate with the lifting frame 310b to lift and transport the cell carrier 300b. Furthermore, the transfer device can cooperate with the support module 320b and drive the support module 320b to switch states.

[0227] In this embodiment, the transfer device in the battery cell carrier transfer equipment can cooperate with the lifting frame 310b to lift the entire battery cell carrier 300b and transport it to the next work station. Furthermore, the transfer device can also drive the support module 320b to switch the state of the support module 320b.

[0228] In other words, this transplanting device can be used with the cell carrier 300b. Furthermore, the transplanting device only needs a linear module with X-axis freedom to drive the support module 320b to switch states. In practical applications, this transplanting device can be a transport crane equipped with an X-axis linear module.

[0229] Clearly, the cell carrier 300b transfer equipment achieves cell transfer through the cell carrier 300b and possesses all the advantages mentioned above brought by the cell carrier 300b, which will not be repeated here.

[0230] In summary, the cell carrier 300b and cell carrier transfer device provided in this application have at least the following beneficial effects:

[0231] The cell carrier 300b includes at least a lifting frame 310b, a support module 320b, and an unfolding positioning structure 30b. The lifting frame 310b is provided with a first guide rod 312b, which is located on both sides of the lifting frame 310b in the Y direction.

[0232] The supporting module 320b is connected to the first guide rod 312b on the hoisting frame 310b. It should be noted that at least some of the components of the supporting module 320b are movably connected to the first guide rod 312b and can move along the first guide rod 312b, thereby realizing state switching.

[0233] Specifically, the support module 320b has an unfolded state and a retracted state. In the unfolded state, the battery cell can be placed in or removed from the support module 320b. In the retracted state, the battery cell is fixed to prevent it from shaking during handling and to ensure the safety of the battery cell during transportation.

[0234] The deployment positioning structure 30b in the cell carrier 300b allows the support module 320b to remain deployed, ensuring that the support module 320b is in the deployed state. This, in turn, ensures that the support module 320b remains deployed during the cell removal and discharge process, improving the safety of the cell removal and discharge process and reducing the risk of damaging the cell.

[0235] In the following description of the embodiments of this application, the terms "X-direction", "Y-direction", and "Z-direction" are determined based on the rectangular coordinate system constructed by the transplanting device provided in this application, and the X-direction, Y-direction, and Z-direction are perpendicular to each other.

[0236] Figure 25 is a schematic diagram of a transplanting device according to one embodiment of this application. Referring to Figure 25, the transplanting device includes a cell carrier transport trolley 100c and a trolley track 200c. The trolley track 200c extends along the Y direction. The cell carrier transport trolley 100c is movably connected to the trolley track 200c and can move along the trolley track 200c, that is, the cell carrier transport trolley 100c can move along the Y direction.

[0237] Figure 26 is a schematic diagram of the battery cell carrier transport crane 100c shown in Figure 25. Referring to Figure 26, the battery cell carrier transport crane 100c includes a traveling frame 10c, a lifting frame support module 20c, a lifting drive mechanism 30c, and an X-axis adjustment module 40c.

[0238] The lifting frame support module 20c is movably connected to the traveling frame 10c and is used to support the battery cell carrier 50c. The lifting drive mechanism 30c is connected to the lifting frame support module 20c to drive the lifting frame support module 20c to lift the lifting frame support module 20c and the battery cell carrier 50c together relative to the traveling frame 10c.

[0239] The X-axis adjustment module 40c is located on the bottom side of the lifting frame support module 20c and is used as a module for loading battery cells in the X-axis adjustment battery cell carrier 50c.

[0240] It should be noted that the battery cell carrier 50c can be used to load multiple battery cells at once. The module for loading the battery cells has a degree of freedom of movement in the X direction, allowing it to switch between an extended and retracted state. In the extended state, the module for loading the battery cells in the battery cell carrier 50c can place the battery cells, and in the retracted state, it can fix the loaded battery cells to prevent them from shaking.

[0241] In this embodiment, the walking frame 10c is movably connected to the overhead crane track 200c, enabling the entire battery cell carrier transport overhead crane 100c to move relative to the overhead crane track 200c, that is, the battery cell carrier transport overhead crane 100c has a Y-direction degree of freedom of movement.

[0242] The lifting frame support module 20c supports the battery cell carrier 50c and is movably connected to the lifting drive mechanism 30c, so as to have Z-axis movement freedom under the drive of the lifting drive mechanism 30c. Furthermore, the X-axis adjustment module 40c can adjust the module in the battery cell carrier 50c used for loading battery cells in the X-axis, thereby switching the state of the module in the battery cell carrier 50c used for loading battery cells.

[0243] In practical applications, after the cell carrier 50c is filled with cells, the cell carrier transport trolley 100c in the transfer device can move to above the cell carrier 50c. The lifting frame support module 20c in the cell carrier transport trolley 100c descends under the action of the lifting drive mechanism 30c and connects with the cell carrier 50c. The X-axis adjustment module 40c connects with the module in the cell carrier 50c used to load the cells.

[0244] It should be noted that, in order to load the battery cells, the module in the battery cell carrier 50c used for loading the battery cells is in an unfolded state. After being filled with battery cells, the module in the battery cell carrier 50c used for loading the battery cells is still in an unfolded state. After the X-axis adjustment module 40c is connected to the module in the battery cell carrier 50c used for loading the battery cells, the module can be adjusted in the X-axis to switch the module to a retracted state.

[0245] After the module for loading the battery cells in the battery cell carrier 50c is in a retracted state, the lifting drive mechanism 30c can drive the lifting frame to support the module 20c and lift the battery cell carrier 50c together to a safe position. Then, the battery cell carrier transport trolley 100c moves the battery cell carrier 50c along the trolley track 200c to the next work station.

[0246] During the movement, the battery cells are fixed in place by the retracted module in the battery cell carrier 50c, preventing them from shaking and ensuring safety.

[0247] As can be seen, in the battery cell carrier transport crane 100c provided in this application, the existing crane's multiple gripper scheme is replaced by an X-axis adjustment module 40c, which realizes the module used to load battery cells in the X-axis adjustable battery cell carrier 50c. This allows for switching the state of the module to prevent battery cell shaking during transport, ensure safety during transport, and reduce costs.

[0248] It should be noted that the cell carrier 50c is used to load airless pouch batteries. When used with the cell carrier transport crane 100c, it can transfer multiple airless pouch batteries at once.

[0249] Figure 27 is a schematic diagram of an X-axis adjustment module 40c according to one embodiment of this application. Referring to Figure 27, the X-axis adjustment module 40c includes an X-axis telescopic mechanism 41c and a locking block structure 42c.

[0250] The block structure 42c is connected to the X-direction telescopic mechanism 41c and is configured to move along the X-direction under the drive of the X-direction telescopic mechanism 41c.

[0251] In this embodiment, the locking block structure 42c is used to lock onto the X-direction side of the module for loading the battery cell in the battery cell carrier 50c, and the X-direction telescopic mechanism 41c is used to drive the locking block structure 42c to move in the X-direction, thereby driving the module for loading the battery cell in the battery cell carrier 50c to move in the X-direction, so as to switch the state of the module.

[0252] Figure 28 is a partial enlarged view of S1 in Figure 27. Referring to Figure 28, in an optional embodiment, the locking block structure 42c includes a fixed guide seat 421c and a locking block 422c. The fixed guide seat 421c includes a fixed block 4211c, a sliding block 4212c, a slide rail 4213c, and an elastic member 4214c.

[0253] The slide rail 4213c is arranged along the X direction. Fixed blocks 4211c are located at both ends of the slide rail 4213c in the X direction and connected to the X-direction telescopic mechanism 41c. Sliding blocks 4212c are slidably connected to the slide rail 4213c and located between the fixed blocks 4211c at both ends. Elastic elements 4214c are clamped between the fixed blocks 4211c and the sliding blocks 4212c at both ends. A locking block 422c is connected to the sliding block 4212c and has a locking groove C.

[0254] In this embodiment, the locking block structure 42c is composed of at least a fixed guide seat 421c and a locking block 422c, wherein the fixed guide seat 421c is composed of at least a fixed block 4211c, a sliding block 4212c, a slide rail 4213c and an elastic element 4214c.

[0255] The locking block 422c is connected to the sliding block 4212c in the fixed guide seat 421c and forms a locking groove C, which can be locked into the module in the cell carrier 50c for loading the cell.

[0256] In addition, since the sliding block 4212c is slidably connected to the slide rail 4213c, the locking block 422c has a degree of freedom of movement in the X direction, and the elastic member 4214c clamped between the fixed block 4211c and the sliding block 4212c can keep the sliding block 4212c in a suitable position.

[0257] It should be understood that during the process of transporting the cell carrier 50c, the cell carrier 50c will inevitably experience slight shaking. Since the locking block 422c has X-direction freedom of movement and under the action of the elastic member 4214c, the cell carrier 50c can buffer the direct impact on the locking block 422c when slight shaking occurs. Moreover, the locking block 422c can be reset under the action of the elastic member 4214c after being impacted, ensuring that the module used to load the cell in the cell carrier 50c is kept in a contracted state as much as possible.

[0258] In an optional embodiment, the card block structure 42c further includes a second detection switch 423c, which is disposed on both sides of the card slot C in the X direction.

[0259] In this embodiment, after the card block 422c is engaged with the module of the battery cell carrier 50c for loading the battery cell, the second detection switch 423c can send a corresponding switching signal to confirm that the card block 422c is engaged in place, so as to proceed to the next state switching action.

[0260] In the embodiment shown in Figure 27, the X-direction telescopic mechanism 41c is a linear drive mechanism based on a lead screw. Specifically, the X-direction telescopic mechanism 41c includes an X-direction drive device 411c, an X-direction transmission belt module 412c, an X-direction lead screw 413c, an X-direction guide rod 414c, and an X-direction telescopic rod 415c.

[0261] X-axis guide rods 414c are located on both sides of the X-axis lead screw 413c in the Y direction. The X-axis drive device 411c is connected to the X-axis lead screw 413c through the X-axis transmission belt module 412c and can drive the X-axis lead screw 413c to rotate.

[0262] The X-direction telescopic rod 415c is rotatably connected to the X-direction lead screw 413c and slidably connected to the X-direction guide rod 414c. The X-direction drive device 411c drives the X-direction transmission belt module 412c to rotate the X-direction lead screw 413c, so that the X-direction telescopic rod 415c moves along the X-direction lead screw 413c and the X-direction guide rod 414c, thereby driving the locking block structure 42c to move in the X direction.

[0263] It should be noted that the X-axis telescopic mechanism 41c is not limited to the embodiment shown in Figure 27. For example, a linear motor, an electric telescopic rod, an electric cylinder, etc. can also be used to ensure that the X-axis degree of freedom can be provided for the block structure 42c.

[0264] Figure 29 is a schematic diagram of the lifting frame support module 20c in Figure 25. Referring to Figure 29, the lifting frame support module 20c includes a lifting frame 21c, a Y-axis retraction mechanism 22c, and a movable support plate assembly 23c.

[0265] The Y-axis retraction mechanism 22c is mounted on the lifting frame 21c. The movable support plate assembly 23c is movably connected to the lifting frame 21c and the Y-axis retraction mechanism 22c, so as to move along the Y-axis under the drive of the Y-axis retraction mechanism 22c. The two ends of the movable support plate assembly 23c in the X-axis extend out of the lifting frame 21c and are used to support the battery cell carrier 50c.

[0266] In this embodiment, the lifting frame support module 20c includes at least a lifting frame 21c, a Y-direction retraction mechanism 22c, and a movable support plate group 23c.

[0267] The Y-axis retraction mechanism 22c is fixedly installed on the lifting frame 21c. The movable support plate assembly 23c is movably connected to the Y-axis retraction mechanism 22c and the lifting frame 21c. The Y-axis retraction mechanism 22c can drive the movable support plate assembly 23c to move along the Y-axis, so that the two ends of the movable support plate assembly 23c in the X-axis can cooperate and connect with the battery cell carrier 50c.

[0268] When the movable support plate assembly 23c is connected to the battery cell carrier 50c, the lifting frame 21c can be lifted and lowered by the lifting drive mechanism 30c, so that the movable support plate assembly 23c can lift and lower the battery cell carrier 50c together.

[0269] In an optional embodiment, the lifting frame 21c includes an upper plate 211c, a lower plate 212c, a lifting screw 213c, and multiple guide rods 214c.

[0270] The upper plate 211c and the lower plate 212c are spaced apart in the Z direction, and multiple guide rods 214c are connected between the upper plate 211c and the lower plate 212c and are slidably connected to the traveling frame 10c.

[0271] The Y-axis retraction mechanism 22c, the movable support plate assembly 23c, and the X-axis adjustment module 40c are all located on the lower plate 212c. The lifting screw 213c is rotatably connected between the upper plate 211c and the lower plate 212c and is rotatably connected to the traveling frame 10c. The lifting drive mechanism 30c is connected to the lifting screw 213c to drive the lifting screw 213c to rotate and to raise and lower the lifting frame 21c.

[0272] In this embodiment, the lifting frame 21c is a frame structure assembled from an upper plate 211c, a lower plate 212c, a lifting screw 213c, and multiple guide rods 214c. The lifting screw 213c and the multiple guide rods 214c are installed between the upper plate 211c and the lower plate 212c. The lifting frame 21c is movably connected to the traveling frame 10c through the lifting screw 213c and the multiple guide rods 214c. The lifting screw 213c is rotatably connected to the traveling frame 10c, and the guide rods 214c are slidably connected to the traveling frame 10c.

[0273] In addition, the Y-direction retraction mechanism 22c, the movable support plate assembly 23c, and the X-direction adjustment module 40c are all installed on the lower plate 212c, and the movable support plate assembly 23c is connected to the Y-direction retraction mechanism 22c.

[0274] Secondly, the lifting screw 213c rotates under the drive of the lifting drive mechanism 30c, converting the rotary motion into the lifting motion of the lifting frame 21c. Furthermore, the guiding effect of multiple guide rods 214c ensures the stability of the lifting frame 21c during the lifting process.

[0275] In an optional embodiment, the movable support plate assembly 23c is disposed on both sides of the lower plate 212c in the Y direction and is movably connected to the lower plate 212c. The Y-direction retraction mechanism 22c can drive the movable support plate assemblies 23c on both sides in the Y direction to move closer to or further away from each other in the Y direction.

[0276] In this embodiment, there are two movable support plate groups 23c, and both movable support plate groups 23c are movably connected to the lower plate 212c and are located on both sides of the lower plate 212c in the Y direction.

[0277] Driven by the Y-direction retraction mechanism 22c, the two movable support plate assemblies 23c move closer to or further away from each other along the Y-direction, thereby adjusting the deployment and retraction of the two movable support plate assemblies 23c in the Y-direction.

[0278] In practical applications, when it is necessary to move the battery cell carrier 50c, the two movable support plate groups 23c are deployed; after the battery cell carrier 50c is moved, the two movable support plate groups 23c are retracted.

[0279] Figure 30 is a partial enlarged view of point S2 in Figure 29. Referring to Figure 30, the Y-direction retraction mechanism 22c includes a Y-direction drive device 221c, a Y-direction retraction transmission belt module 222c, and a Y-direction retraction bidirectional lead screw 223c.

[0280] The Y-axis retraction mechanism 22c is located in the middle of the lower plate 212c. The Y-axis drive device 221c is fixedly installed on the lower plate 212c and can drive the Y-axis retraction bidirectional lead screw 223c to rotate through the Y-axis retraction transmission belt module 222c. The Y-axis retraction bidirectional lead screw 223c can convert the rotation into the Y-axis linear motion of the movable support plate assembly 23c.

[0281] It should be noted that the bidirectional lead screw has two sections of threads with different directions of rotation on a single lead screw, namely one right-hand thread and one left-hand thread. The movable support plate assemblies 23c on both sides are rotatably connected to the two thread sections with different directions of rotation, and the Y-direction retractable bidirectional lead screw 223c, driven by the Y-direction drive device 221c and the Y-direction retractable transmission belt module 222c, enables the movable support plate assemblies 23c on both sides to move synchronously closer to or further away from each other in the Y direction.

[0282] In addition, to ensure the reliability of the movement of the movable support plate assemblies 23c on both sides, Y-guide rail slider mechanisms 24c are provided at both ends of the lower plate 212c in the X direction to slide and connect with the movable support plate assemblies 23c on both sides, so as to ensure that the movable support plate assemblies 23c on both sides maintain translation as much as possible during the movement.

[0283] In the embodiments shown in Figures 29 and 30, the Y-axis retraction mechanism 22c is a linear mechanism constructed based on a bidirectional lead screw. Of course, the Y-axis retraction mechanism 22c is not limited to this; for example, it can also employ a mechanism with two linear motors working together to ensure that the movable support plate assemblies 23c on both sides can synchronously move closer to or further away from each other.

[0284] Please refer to Figure 29. In some optional embodiments, the lifting screw 213c is located at the middle position of the upper plate 211c and the lower plate 212c.

[0285] In this embodiment, the lifting screw 213c is the main lifting transmission functional component. By arranging the lifting screw 213c in the middle position of the lifting frame 21c, it can be ensured that the lifting frame 21c maintains translation during the lifting process as much as possible. This can avoid uneven load distribution among the multiple guide rods 214c and extend their service life.

[0286] In the embodiment shown in Figure 29, both the upper plate 211c and the lower plate 212c are similar rectangular plates. There are four guide rods 214c, which are respectively connected between the four corners of the upper plate 211c and the lower plate 212c. Thus, the lifting frame 21c has a similar rectangular structure. The lifting screw 213c is connected to the middle of the upper plate 211c and the lower plate 212c.

[0287] Figure 31 is a partial enlarged view of point S3 in Figure 29. Referring to Figures 29 and 31, in some optional embodiments, the movable support plate assembly 23c includes a cross plate 231c and a support plate 232c.

[0288] The horizontal plate 231c is movably connected to the lower plate 212c and the Y-direction retraction mechanism 22c, and extends out of the lifting frame 21c at both ends in the X direction. The support plate 232c is connected to both ends in the X direction of the horizontal plate 231c.

[0289] In this embodiment, the X-direction ends of the horizontal plate 231c extend outside the lifting frame 21c, so the support plate 232c connected to the X-direction ends of the horizontal plate 231c is located outside the lifting frame 21c. The support plate 232c is mainly used to connect to the frame of the battery cell carrier 50c.

[0290] Referring to the embodiment shown in Figure 25, the frame of the battery cell carrier 50c is rectangular. When the movable support plate groups 23c on both sides are unfolded in the Y direction, the four support plates 232c are exactly connected to the four corners of the frame of the battery cell carrier 50c.

[0291] In an optional embodiment, the movable support plate group 23c further includes a first detection switch 233c, and each support plate 232c is provided with at least one first detection switch 233c.

[0292] In this embodiment, the first detection switch 233c is mainly used to confirm that the corresponding tray 232c is in contact with the battery cell carrier 50c. Only when the contact is confirmed can the battery cell carrier 50c be further driven to rise and fall.

[0293] Referring to Figure 26, in some optional embodiments, the walking frame 10c includes a frame body 11c and a walking mechanism 12c. Figure 32 is a schematic diagram of the frame body 11c in Figure 26. Referring to Figure 32, the frame body 11c includes a support frame 111c, a support plate 112c, and a transition plate 113c. The transition plate 113c is disposed on both sides of the support frame 111c in the X direction, and the support plate 112c is connected to the support frame 111c and located between the transition plates 113c on both sides. The lifting drive mechanism 30c is disposed on the support plate 112c, and the walking mechanism 12c is connected to the transition plates 113c on both sides.

[0294] In this embodiment, the walking frame 10c has at least a frame body 11c and a walking mechanism 12c, wherein the frame body 11c has at least a load-bearing frame 111c, a load-bearing plate 112c and a transition plate 113c.

[0295] The load-bearing frame 111c can be assembled from multiple beams. The transition plate 113c is fixedly installed on both sides of the load-bearing frame 111c in the X direction. The load-bearing plate 112c is fixedly installed on the load-bearing frame 111c and located between the transition plates 113c on both sides.

[0296] The lifting drive mechanism 30c is fixedly installed on the bearing plate 112c, and the walking mechanism 12c is fixedly installed on the adapter plates 113c on both sides.

[0298] The lifting drive mechanism 30c includes a lifting drive device 31c and a lifting transmission belt module 32c. Referring to Figures 26 and 29, the upper plate 211c of the lifting frame 21c is located above the support plate 112c, and the lower plate 212c is located below the support plate 112c. The guide rod 214c passes through the support plate 112c and is slidably connected to the support plate 112c. The lifting screw 213c passes through the support plate 112c and is rotatably connected to the lifting transmission belt module 32c and the support plate 112c. The lifting drive device 31c drives the lifting screw 213c to rotate by driving the lifting transmission belt module 32c, thereby converting it into the lifting motion of the lifting frame 21c.

[0299] As can be seen, the lifting drive mechanism 30c in the illustrated embodiment adopts a linear drive mechanism based on a lead screw. Of course, it is not limited to this; for example, a linear motor, an electric push rod, etc., can also be used.

[0300] Figure 33 is a schematic diagram of the walking mechanism 12c in Figure 26. In some optional embodiments, the walking mechanism 12c includes a walking drive device 121c, a walking transmission belt module 122c, a walking transmission shaft 123c, and a walking gear 124c, with the walking gear 124c disposed at both ends of the walking transmission shaft 123c.

[0301] The walking drive device 121c drives the walking drive shaft 123c to rotate by driving the walking transmission belt module 122c, which in turn drives the walking gear 124c to rotate.

[0302] In this embodiment, the battery cell carrier transport crane 100c is movably connected to the crane track 200c through the traveling mechanism 12c, so that the battery cell carrier transport crane 100c can move along the crane track 200c.

[0303] Specifically, the traveling mechanism 12c is connected to the overhead crane tracks 200c on both sides and drives the frame body 11c to move along the overhead crane tracks 200c. The frame body 11c drives the lifting frame support module 20c and the battery cell carrier 50c to move together along the overhead crane tracks 200c.

[0304] To ensure reliability during movement, the adapter plates 113c on both sides of the frame body 11c are movably connected to the overhead crane tracks 200c on both sides.

[0305] Figure 34 is a partial enlarged view of S4 in Figure 25. In the embodiment shown in Figure 34, the overhead crane track 200c includes an overhead crane rack 201c and an overhead crane guide rail 202c. The adapter plates 113c on both sides are slidably connected to the overhead crane guide rails 202c on both sides of the overhead crane track 200c, and the traveling gears 124c on both sides are connected to the overhead crane racks 201c on both sides of the overhead crane track 200c.

[0306] In other words, the traveling mechanism 12c and the overhead crane tracks 200c on both sides cooperate to form a gear and rack drive module. Of course, it is not limited to this. For example, each of the overhead crane tracks 200c on both sides has a corresponding linear motor, which is driven by a synchronous dual-motor scheme.

[0307] In summary, the battery cell carrier transport crane 100c and the transfer device provided in this application have at least the following beneficial effects:

[0308] The battery cell carrier crane 100c includes a traveling frame 10c, a lifting frame support module 20c, a lifting drive mechanism 30c, and an X-axis adjustment module 40c. The lifting frame support module 20c supports the battery cell carrier 50c and is movably connected to the lifting drive mechanism 30c, allowing it to have a Z-axis degree of freedom of movement under the drive of the lifting drive mechanism 30c. Furthermore, the X-axis adjustment module 40c can adjust the module in the battery cell carrier 50c used for loading battery cells in the X-axis, thereby switching the state of the module in the battery cell carrier 50c used for loading battery cells.

[0309] In the battery cell carrier transport crane 100c provided in this application, the existing crane's multiple gripper scheme is replaced by an X-axis adjustment module 40c. This allows for the switching of the module's state within the X-axis adjustable battery cell carrier 50c to prevent battery cell swaying during transport, ensuring safety and reducing costs.

[0310] In addition, the transfer device equipped with the battery cell carrier transport crane 100c moves the entire battery cell carrier 50c to the next work station.
