[0062] In the description of this application, the "X direction", "Y direction" and "Z direction" mentioned are all judged based on the rectangular coordinate system constructed by the battery cell production line provided by this application, among which the "Z direction" is also the up and down direction.

[0063] Figure 1 This is a schematic diagram of a battery cell charging and discharging device provided according to one of the embodiments of the present application. Figure 2 for Figure 1 Schematic diagram of the coordination between the overhead crane 120 and the battery cell carrier 300 in FIG. Figure 1 The battery cell charging and discharging equipment includes a transplanting device, a logistics line 500 and a loading and unloading device 600.

[0064] The transplanting equipment includes an overhead crane device 100, a transfer device 200 and a battery cell carrier 300. The overhead crane device 100 includes an overhead crane track 110 and a transport crane 120, wherein the overhead crane track 110 is arranged to extend along the Y direction, and the transport crane 120 is movably connected to the overhead crane track 110 and can move along the overhead crane track 110. The transfer device 200 is arranged below the overhead crane track 110 and the transport crane 120.

[0065] See also Figure 2 The cell carrier 300 includes a hoisting frame 310 and a cell supporting module 320. The cell supporting module 320 is connected to the hoisting frame 310 and is configured to be switchable between an expanded state and a retracted state. The cell supporting module 320 is used to load the cells. The hoisting frame 310 can be hoisted by the transport crane 120 to transport the cell carrier 300 and place or remove the cell carrier 300 from the transfer device 200.

[0066] In this embodiment, the transplanting equipment at least comprises an overhead crane device 100, a transfer device 200 and a battery cell carrier 300. The main function of the transplanting device is to realize the transplanting and transportation of battery cells and to realize the switching of battery cells between different workstations.

[0067] Specifically, the transfer device 200 is located below the overhead crane device 100 , the battery cell carrier 300 is used to load battery cells and can be placed on the transfer device 200 , and the overhead crane device 100 can hoist and move the battery cell carrier 300 to move the battery cells in the battery cell carrier 300 to different workstations.

[0068] The overhead crane device 100 at least comprises an overhead crane track 110 and a transport overhead crane 120 . The transport overhead crane 120 is movably connected to the overhead crane track 110 and can move along the overhead crane track 110 , that is, the transport overhead crane 120 has a Y-direction freedom of movement.

[0069] In addition, the battery cell carrier 300 at least has a hoisting frame 310 and a battery cell supporting module 320. The battery cell supporting module 320 is used to load the battery cells. The hoisting frame 310 can cooperate with the transport crane 120 to realize the hoisting of the entire battery cell carrier 300. Moreover, the battery cell supporting module 320 can be switched between an expanded state and a contracted state. In the expanded state, the battery cells can be placed on the battery cell supporting module 320 through the loading and unloading device 600; in the contracted state, the battery cells placed on the battery cell supporting module 320 can be fixed, reducing the risk of damaging the battery cells due to shaking of the battery cells during transportation.

[0070] In this way, the transport crane 120 can lift the battery cell carrier 300, place the battery cell carrier 300 on the transfer device 200 or lift the battery cell carrier 300 out of the transfer device 200, and drive the battery cell carrier 300 and all the battery cells therein to move along the Y direction, thereby moving the battery cells to different workstations.

[0071] It can be seen that in the transplanting equipment provided in the present application, the overhead crane device 100 cooperates with the cell carrier 300 to indirectly transport the cell, and the transfer device 200 serves as a transfer station for the cell carrier 300 during the cell transport process. In the present application, the overhead crane device 100 does not directly act on the cell to transport it, but after loading the cell on the cell carrier 300, the overhead crane device 100 transports the cell carrier 300 to transport the cell.

[0072] The battery cells are transported by adding an additional battery cell carrier 300 and cooperating with a newly designed overhead crane device 100. The battery cell carrier 300 provides support and protection, thereby ensuring stability during transportation and greatly reducing the risk of damage to the battery cells during transportation.

[0073] It should be noted that soft-pack batteries can be divided into soft-pack batteries with air bags and soft-pack batteries without air bags according to whether they have air bags or not. The existing overhead crane uses a method of clamping air bags for transportation, which is not suitable for soft-pack batteries without air bags. Therefore, the transplanting equipment provided in this application is mainly suitable for the transportation of soft-pack batteries without air bags.

[0074] See also Figure 1 Further, at least part of the logistics line 500 is arranged on the X-axis side of the transplanting device and forms a plurality of loading and unloading stations 510, each loading and unloading station 510 corresponds to a transfer device 200 and a loading and unloading device 600. The logistics line 500 is provided with a cell transfer tray 700 on the loading and unloading stations 510.

[0075] The loading and unloading device 600 is used to transport the battery cells and place the battery cells on the battery cell carrier 300 in the transfer device 200 or the battery cell transfer tray 700 located at the loading and unloading station 510 .

[0076] In this embodiment, the logistics line 500 is used to transport the battery cell transfer tray 700 , and the battery cell transfer tray 700 can be loaded with battery cells and can be docked at the loading and unloading station 510 on the logistics line 500 .

[0077] Each loading and unloading station 510 is matched with a transfer device 200 and a loading and unloading device 600. When a battery cell carrier 300 is placed in the transfer device 200, the battery cells in the battery cell transfer tray 700 are moved to the battery cell carrier 300 through the loading and unloading device 600, or the battery cells in the battery cell carrier 300 are moved to the battery cell transfer tray 700.

[0078] exist Figure 1 In the illustrated embodiment, there are two loading and unloading stations 510, one of which is used as a loading station 511 and the other is used as a unloading station 512. The transfer device 200 corresponding to the loading station 511 is a loading transfer device 20a, and the transfer device 200 corresponding to the unloading station 512 is a unloading transfer device 20b.

[0079] It should be understood that the loading and unloading device 600 corresponding to the loading station 511 is used to transport the battery cells in the battery transfer tray 700 at the loading station 511 to the battery carrier 300 at the loading transfer device 20a, and the loading and unloading device 600 corresponding to the unloading station 512 is used to transport the battery cells in the battery carrier 300 at the unloading transfer device 20b to the battery transfer tray 700 at the unloading station 512.

[0080] Figure 3 for Figure 1 A partial enlarged view of S1 in Figure 2. Figure 3 In some optional embodiments, the loading and unloading device 600 includes a transporting clamp 610 and a clamp track 620, and the clamp track 620 extends along the X direction and crosses the loading and unloading station 510 and the transfer device 200. The transporting clamp 610 is movably connected to the clamp track 620 and can move along the clamp track 620.

[0081] In this embodiment, the transport clamp 610 is used to clamp the battery cells. In some optional embodiments, the battery cells are clamped at the pole ears at both ends of the battery cells, and can be reciprocated along the clamp track 620 between the loading and unloading station 510 and the transfer device 200, so as to place the battery cells on the battery cell carrier 300 in the transfer device 200 or the battery cell transfer tray 700 located at the loading and unloading station 510.

[0082] In a specific application, the transport gripper 610 includes a plurality of grippers 611 and a plurality of linear modules. The plurality of grippers cooperate to grasp a plurality of battery cells at a time. The plurality of linear modules enable the plurality of grippers to be raised and lowered, and the Y-direction spacing and X-direction spacing between the grippers can be adjusted. Controlling the Y-direction spacing between the grippers can adapt to battery cells of different lengths, and controlling the X-direction spacing between the grippers can adjust the X-direction spacing between the gripped battery cells.

[0083] 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 the like in conjunction with a motor, or a linear motor, an electric push rod, a cylinder and the like.

[0084] exist Figure 1 In the illustrated embodiment, the number of the clamping jaw tracks 620 is 2 and they are arranged in parallel and spaced apart in the Y direction, i.e., a double-track solution is adopted to ensure that the transporting clamping jaw 610 moves in the X direction. In addition, the transporting clamping jaw 610 is driven along the clamping jaw track 620 by a gear rack transmission mechanism in conjunction with a motor. Of course, the driving is not limited to the gear rack transmission mechanism. For example, a belt transmission mechanism, a ball screw and the like in conjunction with a motor can also be used, or a linear motor can be used directly.

[0085] In some optional embodiments, the transplanting device further includes a cell clamp 400 , and the cell clamp 400 and the transfer device 200 are spaced apart in the Y direction. The cell carrier 300 is placed on or detached from the cell clamp 400 under the transportation of the overhead traveling device 100 .

[0086] In the present embodiment, the battery cell clamp 400 is used to assist the battery cell detection. Specifically, the battery cell clamp 400 can apply pressure to the battery cells in the battery cell carrier 300 to cooperate with the detection device to detect the battery cells.

[0087] Since the cell fixture 400 and the cell carrier 300 are arranged at intervals in the Y direction, the overhead travelling device 100 can switch the cell carrier 300 between the transfer device 200 and the cell fixture 400. The transfer device 200 is located at the transfer station, and the cell fixture 400 is located at the inspection station.

[0088] In order to facilitate a better understanding of this solution, the following is a brief description Figure 1 The process of transporting battery cells in the battery charging and discharging equipment shown.

[0089] First, the incoming materials of the logistics line 500 stop at the loading station 511, that is, the battery cell transfer tray 700 loaded with battery cells is parked at the loading station 511, and the battery cell transfer tray 700 is transported to the battery cell support module 320 in the battery cell carrier 300 at the loading transfer device 20a by the loading and unloading device 600, until the number of battery cells in the battery cell carrier 300 reaches the set number. It can be understood that in this process, the battery cell support module 320 is in an unfolded state, so that the loading and unloading device 600 can put the battery cells in from top to bottom.

[0090] Next, the transport crane 120 in the crane device 100 moves to the position above the loading transfer device 20a, and the transport crane 120 cooperates with the hoisting frame 310 to hoist the entire battery cell carrier 300. After confirming that the battery cell carrier 300 is separated from the loading transfer device 20a, the battery cell support module 320 switches to the retracted state, and the battery cell carrier 300 is moved to the top of the battery cell fixture 400 along the Y direction. The battery cell support module 320 switches to the expanded state again, and the battery cell carrier 300 is placed on the battery cell fixture 400. It can be understood that in this process, the battery cell support module 320 is in a retracted state to fix the loaded battery cells, reducing the risk of shaking of the battery cells during transportation.

[0091] After the inspection of the cells in the cell carrier 300 is completed, the cell support module 320 is in the expanded state, and the cell carrier 300 is hoisted by the overhead crane 120. After confirming that it is detached from the cell fixture 400, the cell support module 320 switches to the retracted state, and the cell carrier 300 moves along the Y direction to the position above the unloading transfer device 20b, and the cell carrier 300 is placed on the unloading transfer device 20b. After confirming that the cell carrier 300 is placed on the unloading transfer device 20b, the cell support module 320 switches to the expanded state again, and the cell support module 320 is in the expanded state, so that the loading and unloading device 600 can take the cell out of the cell support module 320.

[0092] 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 through the loading and unloading device 600. After the battery cell transfer tray 700 is filled with battery cells, the logistics line 500 can move the battery cell transfer tray 700 out of the unloading station 512, thereby forming a closed battery cell charging and discharging detection production line to realize batch detection of battery cells.

[0093] From the above, it can be seen that the battery cell charging and discharging equipment equipped with the transplanting equipment provided in the present application can transport the battery cells between the transfer device 200 and the battery cell clamp 400 through the overhead crane device 100 in cooperation with the battery cell carrier 300, which can greatly reduce the risk of damaging the battery cells during transportation.

[0094] Figure 4 for Figure 2 Schematic diagram of the battery cell carrier 300 in FIG. Figure 4 In some optional embodiments, the battery cell supporting module 320 includes a plurality of battery cell supporting plate groups 321 and at least one battery cell supporting film 322;

[0095] Multiple battery cell supporting plate groups 321 are arranged along the X direction, and the two sides of the battery cell supporting film 322 in the X direction are detachably connected to the two battery cell supporting plate groups 321, and the battery cell supporting film 322 is provided with a downwardly extending concave shape between two adjacent battery cell supporting plate groups 321, and the concave shape forms a battery cell placement area P.

[0096] In this embodiment, the battery cell supporting module 320 has at least multiple battery cell supporting plate groups 321 and at least one battery cell supporting film 322. The battery cell supporting film 322 is a soft film material, which cooperates with the multiple battery cell supporting plate groups 321 and forms a downwardly extending concave shape between two adjacent battery cell supporting plate groups 321. The concave shape corresponds to a battery cell placement area P where the battery cells can be placed.

[0097] In an optional embodiment, the number of battery cell supporting films 322 is 1, and the length of the battery cell supporting film 322 in the X direction is longer than the X-direction spacing between the two outermost battery cell supporting plate groups 321 in the X direction. In this way, after the battery cell supporting film 322 is installed on the multiple battery cell supporting plate groups 321, part of the battery cell supporting film 322 can extend downward from between two adjacent battery cell supporting plate groups 321 due to gravity to form a concave shape.

[0098] In this embodiment, the cell supporting film 322 is detachably connected to the two outermost cell supporting plate groups 321. The cell supporting film 322 and the cell supporting plate group 321 are detachably connected mainly to facilitate replacement of the damaged cell supporting film 322. Of course, in this embodiment, the entire cell supporting film 322 needs to be replaced, which is relatively costly.

[0099] In another optional embodiment, there are multiple battery cell supporting films 322, and one battery cell supporting film 322 is provided between any two adjacent battery cell supporting plate groups 321. The X-direction length of each battery cell supporting film 322 is greater than the X-direction spacing between two adjacent battery cell supporting plate groups 321. In this way, the battery cell supporting module 320 extends downward between two adjacent battery cell supporting plate groups 321 due to gravity to form a concave shape.

[0100] In this embodiment, both sides of the cell supporting film 322 in the X direction are detachably connected to two adjacent cell supporting plate groups 321 , and the length of the cell supporting film 322 in the X direction is relatively short, so the replacement cost is relatively low.

[0101] In a specific application, the battery cell supporting film 322 can be detachably connected to the battery cell supporting plate assembly 321 through parts such as magnetic suction parts and snap fasteners, but it is certainly not limited thereto.

[0102] In some optional embodiments, the battery cell supporting plate assembly 321 includes sliding bearing seats 3211 located on both sides of the Y direction, and the sliding bearing seats 3211 on both sides are slidably matched with the guide rods 312 on both sides.

[0103] In this embodiment, the sliding bearing seat 3211 in the battery cell supporting plate set 321 is slidably connected to the guide rod 312 , so that the battery cell supporting plate set 321 can move along the guide rod 312 .

[0104] For the fixed battery cell supporting plate group 321 b , a limiting hoop is provided on the guide rod 312 to limit the sliding bearing seat 3211 in the fixed battery cell supporting plate group 321 b so that the fixed battery cell supporting plate group 321 b cannot move.

[0105] In addition, the chain 323 passes through the sliding bearing seats 3211 in each battery cell supporting plate group 321 to connect each battery cell supporting plate group 321 in sequence.

[0106] Figure 5 for Figure 4 A partial enlarged view of S3 in Figure 2. Figure 5 In some optional embodiments, the hanging frame 310 is provided with guide rods 312 extending along the X direction, the guide rods 312 are located on both sides of the hanging frame 310 in the Y direction, and each battery cell supporting plate group 321 is connected to the guide rods 312 on both sides.

[0107] The cell supporting module 320 further includes a chain 323 , which is disposed on both sides of the plurality of cell supporting plate assemblies 321 in the Y direction and connects the plurality of cell supporting plate assemblies 321 in sequence along the X direction.

[0108] In this embodiment, the two sides of the hanging frame 310 in the Y direction have guide rods 312 , and the guide rods 312 on both sides extend along the X direction. The two ends of the cell supporting plate group 321 in the Y direction are correspondingly connected to the guide rods 312 on both sides in the Y direction.

[0109] Furthermore, the cell supporting module 320 also includes chains 323 arranged at both ends of the cell supporting plate groups 321 in the Y direction, and the chains 323 connect the cell supporting plate groups 321 in sequence along the X direction, that is, multiple cell supporting plate groups 321 are connected in series.

[0110] In a specific application, at least part of the battery cell supporting plate group 321 is movably connected to the guide rods 312 on both sides, that is, part of the battery cell supporting plate group 321 can move along the guide rods 312, so that only part of the battery cell supporting plate group 321 needs to be driven to move, and the remaining movable battery cell supporting plate group 321 can be driven to move together to achieve state switching.

[0111] See also Figure 4 In a further optional embodiment, the two outermost battery cell supporting plate groups 321 in the X direction are the active battery cell supporting plate group 321a and the fixed battery cell supporting plate group 321b.

[0112] The fixed battery cell supporting plate group 321 b is fixedly connected to the guide rod 312 , and the remaining battery cell supporting plate groups 321 are movably connected to the guide rod 312 and can move in the X direction relative to the hanging frame 310 .

[0113] The transport crane 120 is configured to be connected to the active battery cell supporting plate group 321 a and drive all active battery cell supporting plate groups 321 to move in the X direction to achieve switching between the expanded state and the retracted state.

[0114] In this embodiment, except for the fixed battery cell supporting plate group 321b which cannot move along the guide rod 312, the remaining battery cell supporting plate groups 321 can all move along the guide rod 312, wherein one of the movable battery cell supporting plate groups 321 is the active battery cell supporting plate group 321a, the active battery cell supporting plate group 321a and the fixed battery cell supporting plate group 321b are respectively the two outermost battery cell supporting plate groups 321 in the X direction, and the movable battery cell supporting plate group 321 between the active battery cell supporting plate group 321a and the fixed battery cell supporting plate group 321b is the follower battery cell supporting plate group 321c.

[0115] As can be seen from the foregoing, each battery cell supporting plate group 321 is connected in sequence through the chain 323. In a specific application, the active battery cell supporting plate group 321a is driven to move by the transport crane 120, and the active battery cell supporting plate group 321a drives the follower battery cell supporting plate group 321c to move in the X direction, thereby enabling the battery cell supporting film 322 located between two adjacent battery cell supporting plate groups 321 to be retracted and expanded, that is, the battery cell supporting module 320 is switched between the expanded state and the retracted state.

[0116] Please combine Figure 5In the unfolded state, the cell placement area P formed by the cell support film 322 is wide at the top and narrow at the bottom, which is convenient for placing the cells from top to bottom. In 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 spacing between the cell support plate groups 321 decreases until the side walls of any two adjacent cell support plate groups 321 are against each other, and the cells are clamped and fixed by the cell support film 322 and kept vertical. At this time, the cell support module 320 is in a retracted state. Carrying the cell carrier 300 in the retracted state can reduce the risk of cell shaking.

[0117] Figure 6 for Figure 2 A schematic diagram of the overhead crane 120 is shown in FIG. Figure 7 for Figure 2 The enlarged view of the part at S2 in the figure. Figure 2 , Figure 6 and Figure 7 In some optional embodiments, the transport crane 120 includes an X-direction adjustment module 122 , and the X-direction adjustment module 122 is used to adjust the battery cell supporting module 320 in the X-direction to switch the state of the battery cell supporting module 320 .

[0118] In this embodiment, the overhead crane 120 has at least an X-axis adjustment module 122, which can provide X-axis freedom of movement to drive some of the component modules in the battery cell supporting module 320 to move, thereby switching the battery cell supporting module 320 between an expanded state and a contracted state.

[0119] In a specific application, the X-direction adjustment module 122 can cooperate with the active battery cell supporting plate group 321a to drive the active battery cell supporting plate group 321a to move in the X-direction, and then drive the follower battery cell supporting plate group 321c to move in the X-direction to achieve the purpose of switching the state.

[0120] exist Figure 7 In the illustrated embodiment, the X-axis adjustment module 122 is formed with a downwardly opening slot C, and the active battery cell supporting plate group 321a is provided with an upwardly protruding shift block 324, which can be embedded in the slot C, so that the X-axis adjustment module 122 can be connected with the shift block 324 on the active battery cell supporting plate group 321a, thereby driving the active battery cell supporting plate group 321a.

[0121] Figure 8 FIG. 1 is a schematic diagram of an X-axis adjustment module 122 provided according to one embodiment of the present application. Figure 8The X-direction adjustment module 122 includes an X-direction adjustment block structure 1221 and an X-direction telescopic mechanism 1222. The X-direction adjustment block structure 1221 is connected to the X-direction telescopic mechanism 1222 and is configured to move along the X-direction under the drive of the X-direction telescopic mechanism 1222.

[0122] In this embodiment, the X-direction adjustment module 122 has at least an X-direction adjustment block structure 1221 and an X-direction telescopic mechanism 1222. The X-direction adjustment block structure 1221 is used to cooperate with the active battery cell supporting plate group 321a in the battery cell supporting module 320. The X-direction telescopic mechanism 1222 is used to move the X-direction adjustment block structure 1221 in the X-direction, thereby driving the active battery cell supporting plate group 321a to move in the X-direction to switch the state of the battery cell supporting module 320.

[0123] exist Figure 8 In the illustrated embodiment, the card slot C is located in the X-direction adjustment card block structure 1221 , and when the shift block 324 on the active battery cell supporting plate assembly 321 a is embedded in the card slot C, the X-direction adjustment card block structure 1221 can be connected to the shift block 324 .

[0124] Figure 8 The X-direction telescopic mechanism 1222 in the illustrated embodiment is a mechanism with telescopic function formed by a ball screw and a motor, but is certainly not limited to this. For example, an electric push rod, a pneumatic cylinder, an oil cylinder, etc. may be directly used to drive the X-direction adjustment block structure 1221 to move in the X-direction.

[0125] Fig. 9 for Figure 4 A partial enlarged view of S6 in Figure 2. Fig.12 In some optional embodiments, a clamping plate 315 is provided on one side of the hoisting frame 10 close to the active battery cell supporting plate group 321 a , and a positioning bead 325 is provided on the active battery cell supporting plate group 321 a .

[0126] In the expanded state, the positioning clamping plate 315 is clamped to the positioning bead 325. In the retracted state, the positioning clamping plate 315 is disconnected from the positioning bead 325.

[0127] It should be understood that when the cell support module 320 switches between different states, the position of the positioning beads 325 changes with the movement of the active cell support plate group 321a. When the cell support module 320 is in the expanded state, the positioning beads 325 are located at the location of the positioning card plate 315 and connected to the positioning card plate 315. The positioning beads 325 are connected to the positioning card plate 315 to maintain the expanded state of the cell support module 320, so as to facilitate the removal of the cell. In addition, when the cell support module 320 switches from the expanded state to the contracted state, the positioning beads 325 are separated from the positioning card plate 315.

[0128] In this embodiment, positioning beads 325 are provided on both sides of the Y direction of the active battery support plate group 321a. Correspondingly, clamping plates 315 are also provided on both sides of the Y direction of the lifting frame 310. 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.

[0129] In a specific application, the clamping plate 315 is provided with a notch to cooperate with the positioning bead 325 , and the positioning bead 325 can rotate to facilitate connection with the clamping plate 315 or separation from the clamping plate 315 .

[0130] Please combine Figure 2 and Figure 4 In some optional embodiments, the transport crane 120 includes crane support plates 121 disposed on both sides of the Y direction, and the crane support plates 121 on both sides are extended along the X direction and are configured to be able to approach or move away from each other along the Y direction;

[0131] The hoisting frame 310 is provided with a plurality of hoisting pallets 311 , and when the overhead travelling vehicle supporting plates 121 on both sides are away from each other, one end of the overhead travelling vehicle supporting plate 121 in the X direction can be connected to the corresponding hoisting pallet 311 .

[0132] In this embodiment, the transport crane 120 is equipped with crane support plates 121 on both sides of the Y direction and capable of retracting and extending in the Y direction to cooperate with the hoisting support plates 311 in the hoisting frame 310 , thereby being able to hoist the entire battery cell carrier 300 .

[0133] Specifically, when the crane support plates 121 on both sides are away from each other in the Y direction, that is, when the two are spread out in the Y direction, the X-direction ends of the crane support plates 121 on both sides can cooperate with the corresponding lifting support plates 311 in the lifting frame 310, and the cooperation method can be overlapped or snap-on connection.

[0134] When the crane supporting plates 121 on both sides approach each other in the Y direction, that is, when the two are contracted in the Y direction, the X-direction ends of the crane supporting plates 121 on both sides can be disconnected from the corresponding hoisting plates 311 in the hoisting frame 310.

[0135] In this way, the transport crane 120 and the cell carrier 300 can be connected or disconnected by controlling the retraction and extension of the crane support plates 121 on both sides.

[0136] It should be understood that when the crane support plates 121 on both sides are in the unfolded state, the battery cell carrier 300 can be hoisted. After the battery cell carrier 300 is placed on the transfer device 200 or the battery cell fixture 400, the crane support plates 121 on both sides can be switched from unfolded to retracted, so that the transport crane 120 can be disconnected from the battery cell carrier 300.

[0137] Please combine Figures 2 to 4The hoisting frame 310 is a rectangular frame structure assembled from a plurality of beams, wherein the hoisting support plate 311 is arranged at the corner of the hoisting frame 310. The X-direction length of the overhead travelling carriage 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 at the inner side of the corner of the hoisting frame 310.

[0138] Therefore, the crane supporting plates 121 on both sides can enter the area enclosed by the hoisting frame 310 along the Z direction when retracted. After the relative positions of the crane supporting plates 121 and the hoisting frame 310 in the Z direction are appropriate, the crane supporting plates 121 on both sides can be unfolded until the two ends of the crane supporting plate 121 on one side in the X direction cooperate with the hoisting supporting plates 311 on both sides of the hoisting frame 310 on the same side in the Y direction.

[0139] Fig.10 for Figure 4 A local enlarged view of S4 in the figure. Fig.11 for Figure 6 A partial enlarged view of S5 in Figure 2. Fig.10 and Fig.11 In some optional embodiments, the lifting support plate 311 is provided with a positioning pin 313 extending downward, and the X-axis end plate section of the overhead crane supporting plate 121 is provided with a positioning pin hole H1. When the overhead crane supporting plates 121 on both sides are away from each other, the positioning pin 313 and the positioning pin hole H1 can be aligned in the Z direction.

[0140] In this way, by raising and lowering the overhead travelling support plate 121 , the overhead travelling support plate 121 unfolded on both sides can be connected to or disconnected from the hoisting support plate 311 .

[0141] Furthermore, the crane support plate 121 is also provided with a hoisting in place detection switch 1211, which is located at the X-direction end of the crane support plate 121, and the hoisting support plate 311 is provided with a hoisting in place stopper 314. After the crane support plates 121 on both sides move into place, the hoisting in place stopper 314 can trigger the hoisting in place detection switch 1211 to send a switch signal to confirm that the crane support plate 121 is in the required position for hoisting.

[0142] It should be noted that when the Z-axis position of the overhead travelling carriage supporting plate 121 meets the height requirement for cooperating with the hoisting frame 310 for hoisting, the card slot C in the X-axis adjustment module 122 just accommodates the shifting block 324 on the active battery supporting plate assembly 321a.

[0143] As can be seen from the above, the overhead travelling support plate 121 has the freedom of lifting in the Z direction, so that it can cooperate with the lifting frame 310 to lift the entire battery cell carrier 300. Moreover, when the overhead travelling support plate 121 reaches the height position required for lifting and cooperating with the battery cell carrier 300 in the Z direction, the X-direction adjustment module 122 is just connected to the active battery cell support plate group 321a, indicating that the X-direction adjustment module 122 also has the freedom of lifting in the Z direction. That is, the overhead travelling support plate 121 and the X-direction adjustment module 122 are configured to be able to lift in the Z direction.

[0144] See also Figure 2 In some optional embodiments, the transport crane 120 further includes a lifting frame 123 and a walking frame 124, and the walking frame 124 is movably connected to the crane track 110 and can move along the crane track 110. The lifting frame 123 is movably connected to the walking frame 124 and can be lifted and lowered in the Z direction relative to the walking frame 124.

[0145] The overhead travelling carriage supporting plate 121 and the X-direction adjusting module 122 are both disposed on the lifting frame 123 so as to be able to be lifted and lowered together with the lifting frame 123. Thus, the overhead travelling carriage supporting plate 121 and the X-direction adjusting module 122 have a Z-direction lifting freedom.

[0146] In a further optional embodiment, the lifting frame 123 includes an upper plate 1231, a lower plate 1232, a lifting screw 1233 and a plurality of guide rods 1234. The upper plate 1231 and the lower plate 1232 are spaced apart in the Z direction, and the plurality of guide rods 1234 are connected between the upper plate 1231 and the lower plate 1232 and are slidably connected to the walking frame 124.

[0147] See also Figure 2 Furthermore, the overhead crane 120 further includes a lifting drive mechanism 125, which is disposed on the upper plate 1231 and is used to drive the lifting screw 1233 to rotate so that the lifting frame 123 can be lifted and lowered in the Z direction relative to the walking frame 124. That is, the rotary motion is converted into the Z-direction linear motion of the lifting frame 123 by the lifting screw 1233.

[0148] exist Figure 2 In the illustrated embodiment, the lifting drive mechanism 125 uses a motor in conjunction with a synchronous belt to drive the lifting screw 1233 to rotate. Of course, it is not limited to this. For example, a motor in conjunction with a gear set can also be used to drive the lifting screw 1233 to rotate.

[0149] See also Figure 6In a further optional embodiment, the transport crane 120 also includes a Y-direction retracting and extending mechanism 126, which is arranged on the lower plate 1232, and the crane supporting plates 121 on both sides of the Y-direction are movably connected to the lower plate 1232 and the Y-direction retracting and extending mechanism 126. The crane supporting plates 121 on both sides of the Y-direction can approach or move away from each other under the drive of the Y-direction retracting and extending mechanism 126.

[0150] It should be noted that, in order to ensure that the overhead travelling carriage supporting plate 121 can translate stably along the Y direction, the overhead travelling carriage supporting plate 121 and the lower plate 1232 are movably connected via a guide rail slider transmission mechanism.

[0151] exist Figure 6 In the illustrated embodiment, the Y-direction retracting and extending mechanism 126 is a retracting and extending mechanism based on a bidirectional lead screw, specifically, the bidirectional lead screw is driven by a motor in cooperation with a synchronous belt, and the overhead travelling carriage supporting plates 121 on both sides of the Y-direction are respectively connected to different rotation direction rod segments of the bidirectional lead screw. Of course, the Y-direction retracting and extending mechanism 126 is not limited thereto, and may also be, for example, a combination of two linear motors, a combination of two cylinders, etc.

[0152] In some optional embodiments, the transport crane 120 further includes a traveling mechanism 127 , which is disposed on the traveling frame 124 and is used to cooperate with the crane track 110 to enable the transport crane 120 to move along the crane track 110 .

[0153] exist Figure 6 In the illustrated embodiment, a gear rack transmission mechanism is formed between the traveling mechanism 127 and the overhead travelling vehicle track 110, and the motor cooperates with the synchronous belt and the transmission shaft to drive the gears on both sides of the Y direction to rotate, thereby realizing the movement of the overhead travelling vehicle track on both sides of the Y direction. Of course, the traveling mechanism 127 is not limited to this, and can also be, for example, a linear motor disposed on both sides of the traveling frame 124 in the Y direction.

[0154] Fig.12 for Figure 1 Schematic diagram of the transfer device 200. Fig.13 for Fig.12 Schematic diagram of the guide clamp mechanism 210 in FIG. Fig.12 and Fig.13 In some optional embodiments, the transfer device 200 includes a guide clamp mechanism 210 disposed on both sides of the Y direction. The guide clamp mechanism 210 includes a clamp gap adjustment plate group 211 and a plurality of guide clamps 212. The clamp gap adjustment plate group 211 is extended along the X direction, and the plurality of guide clamps 212 are spaced apart from the clamp gap adjustment plate group 211 along the X direction.

[0155] The battery cells loaded in the battery cell supporting module 320 can be placed between two adjacent guide clips 212 , and the clamp gap adjustment plate group 211 is configured to synchronously adjust the gaps between the multiple guide clips 212 to adapt to battery cells of different thicknesses.

[0156] In this embodiment, the guide clamp mechanisms 210 on both sides of the transfer device 200 in the Y direction are used to limit the battery cells in the battery cell carrier 300 placed at the transfer device 200. Specifically, the guide clamp mechanism 210 at least includes a clamp gap adjustment plate group 211 and a plurality of guide clamps 212, the clamp gap adjustment plate group 211 is extended and arranged along the X direction, and each guide clamp 212 is installed on the clamp gap adjustment plate group 211 at intervals along the X direction.

[0157] Specifically, since the plurality of guide clips 212 are arranged at intervals, a space for accommodating the battery cells is formed between two adjacent guide clips 212 , and the adjacent battery cells are separated by the guide clips 212 on both sides, thereby reducing the risk of collision damage to the battery cells.

[0158] In combination with the above, the battery cells are placed on the battery cell supporting films 322 between two adjacent battery cell supporting plate groups 321. In other words, each battery cell supporting film 322 between two adjacent battery cell supporting plate groups 321 can be inserted into each gap formed by multiple guide clips 212 one by one, that is, the battery cell supporting film 322 is first limited in the X direction, and then the battery cell is placed from top to bottom in the battery cell supporting film 322 that has been limited in the X direction.

[0159] In addition, the clamp gap adjustment plate group 211 can synchronously adjust the gaps between the guide clamps 212 so as to limit the battery cells of different thicknesses, thereby ensuring that the transfer device 200 has good versatility.

[0160] Fig.14 for Fig.13 A partial enlarged view of S7 in Figure 1. Fig.14 In some optional embodiments, the guide clamp 212 includes a fixed clamp plate 2121 and a movable clamp plate 2122, and the fixed clamp plate 2121 and the movable clamp plate 2122 are spaced apart in the X direction.

[0161] The clamp gap adjustment plate set 211 includes an upper adjustment plate 2111 and a lower adjustment plate 2112, which are spliced ​​in the Z direction. The fixed clamp plate 2121 in each guide clamp 212 is connected to the upper adjustment plate 2111, and the movable clamp plate 2122 in each guide clamp 212 is connected to the lower adjustment plate 2112.

[0162] The lower adjustment plate 2112 can move relative to the upper adjustment plate 2111 in the X direction to synchronously adjust the distance between the movable clamping plate 2122 of one of two adjacent guide clamps 212 and the fixed clamping plate 2121 of the other one.

[0163] In this embodiment, the guide clamp 212 is composed 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 adjustment plate set 211 is composed of an upper adjustment plate 2111 and a lower adjustment plate 2112 stacked up and down.

[0164] Among them, the fixed clamping plate 2121 in each guide clamp 212 is fixedly mounted on the upper adjustment plate 2111, and the movable clamping plate 2122 is fixedly mounted on the lower adjustment plate 2112. It should be noted that, for any two adjacent guide clamps 212, the movable clamping plate 2122 of one is close to the fixed clamping plate 2121 of the other. The lower adjustment plate 2112 can move along the X direction, thereby driving the fixed clamping plate 2121 to move, so that the X-direction spacing between two adjacent guide clamps 212 can be adjusted to adapt to battery cells of different thicknesses.

[0165] In the illustrated embodiment, the upper adjustment plate 2111 is provided with a long through hole H1, and a single movable clamping plate 2122 corresponds to two long through holes H1, and the long through hole H1 extends along the X direction and is penetrated by a stud 213, and the movable clamping plate 2122 is matched with the lower adjustment plate 2112 through the stud 213. It should be understood that when the lower adjustment plate 2112 is moved, the stud 213 can move in the long through hole H1, and of course, the X-direction length of the long through hole H1 can also limit the moving range of the movable clamping plate 2122. It should be noted that the connection method of the lower adjustment plate 2112 is not limited to the illustrated embodiment.

[0166] Fig.15 for Fig.12 Schematic diagram of the alignment mechanism 220 in FIG. Fig.15 In some optional embodiments, the transfer device 200 further includes a battery cell alignment mechanism 220 , and the battery cell alignment mechanism 220 is located on the Y-outside side of the guide clamp mechanism 210 .

[0167] The cell alignment mechanism 220 includes a push rod 221 extending along the X direction. The push rod 221 is configured to be movable toward the guide clamp mechanism 210 along the Y direction to align the ends of the multiple cells between the guide clamps 212 in the X direction.

[0168] It should be understood that the loading and unloading device 600 can only remove the discharged 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, facilitating the process of removing and transporting the cells.

[0169] Specifically, the cell alignment mechanism 220 is located outside the guide clamp mechanism 210 in the Y direction and has a push rod 221 that can reciprocate in the Y direction, so that the push rod 221 can move toward the guide clamp mechanism 210 and abut against one end of the multiple cells in the Y direction between the guide clamps 212, so that the one end of the multiple cells in the Y direction is aligned in the X direction. Here, the X-direction alignment means that the Y-direction ends of the cells are aligned in the X direction.

[0170] It should be noted that since the equipment provided in the application is mainly suitable for airbag-free battery cells, the position clamped by the clamping claws 611 in the loading and unloading device 600 is the pole ear part on both sides of the battery cell. The two ends of the battery cell in the Y direction are the pole ears. Aligning the pole ears is more conducive to the loading and unloading device 600 to pick up and place.

[0171] In a specific application, the push rod 221 can be provided with freedom of movement by a pneumatic cylinder, an oil cylinder, an electric push rod, etc., so that the push rod 221 can reciprocate in the Y direction.

[0172] In a further optional embodiment, the transfer device 200 also includes a transfer support frame 230, and the transfer support frame 230 is provided with a battery cell carrier positioning structure, which is used to determine the placement position of the battery cell carrier 300 at the transfer device 200 so that each battery cell loaded in the battery cell carrier 300 is located between two adjacent guide clips 212.

[0173] In this embodiment, the transfer device 200 further includes a transfer support frame 230 , which is a frame structure formed by multiple beams and plates. The guide clamp mechanism 210 is connected to the transfer support frame 230 and is at least partially located inside the transfer support frame 230 .

[0174] exist Fig.12 In the illustrated embodiment, the cell carrier positioning structure includes a limiting support block 231 located at the four corners of the transfer support frame 230, and the limiting support block 231 is formed with a groove with a top opening. 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 block 231 .

[0175] In the figure, the four limiting protrusions 316 on the hanging frame 310 are the two ends of the guide rod 312 in the X direction on both sides of the Y direction, that is, the two ends of the guide rod 312 in the X direction extend out of the hanging frame 310 to form the limiting protrusions 316. Of course, the protrusions can also be directly installed on the hanging frame 310 as the limiting protrusions 316. It can be designed according to needs.

[0176] Furthermore, the battery cell carrier positioning mechanism also includes a positioning detection switch 232 arranged diagonally. When the battery cell carrier 300 is positioned accurately, the hoisting frame 310 just abuts against the positioning detection switch 232 and sends a switch signal to confirm that the battery cell carrier 300 is positioned accurately.

[0177] Of course, the cell carrier positioning structure is not limited to the cooperation between the limiting support block 231 and the limiting protrusion 316 , and may also be, for example, the cooperation between the positioning pin and the pin hole.

Fig.16 In some optional embodiments, the battery cell clamp 400 is a battery cell restraint clamp without a battery cell supporting film and is provided with a positioning block 410 to limit the placement position of the battery cell carrier 300 .

[0179] 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 frame 420. The pressure plate module 430 is configured to be able to move in the X direction for contraction and expansion. The pressure plate module 430 includes a plurality of pressure plates that can move in the X direction, and there is no battery cell supporting film 322 between two adjacent pressure plates.

[0180] That is, compared with the cell support module 320, the pressure plate module 430 does not have the cell support film 322, that is, it is a cell restraint fixture without a cell support film. In addition, when the pressure plates in the pressure plate module 430 are close to each other (i.e. contracted), they can apply pressure to the cell to prepare for the subsequent charging detection process.

[0181] The battery cell fixture 400 includes a positioning block 410, which is provided with an upwardly open groove and is arranged at four corners of a fixture frame 420 ( Fig.16 Only a positioning block 410 at a corner position is shown in the figure. When the battery carrier 300 is placed on the battery fixture 400, the limiting protrusion 316 at the hanging frame 310 is just embedded in the groove of the positioning block 410 to achieve the positioning purpose.
