[0046] In the description of the present application, the "X direction", "Y direction", "Z direction" mentioned is based on the Cartesian coordinate system constructed by the transplanting device provided in the present application. The X direction, Y direction and Z direction are perpendicular to each other.

[0047] Figure 1 The schematic diagram of the transplanting device provided according to one embodiment of the present application is shown in Figure 1 The transplanting device includes a battery cell carrier handling crane 100 and a crane track 200, the crane track 200 is arranged along the Y direction, the battery cell carrier handling crane 100 is movably connected with the crane track 200 and can move along the crane track 200, that is, the battery cell carrier handling crane 100 can move along the Y direction.

[0048] Figure 2 The schematic diagram of the battery cell carrier handling crane 100 in Figure 1 The schematic diagram of the battery cell carrier handling crane 100 in Figure 2The battery cell carrier handling crane 100 comprises a walking frame 10, a lifting frame supporting module 20, a lifting drive mechanism 30 and an X-direction adjusting module 40.

[0049] The lifting frame supporting module 20 is movably connected to the walking frame 10 and is used to support the battery cell carrier 50. The lifting drive mechanism 30 is connected to the lifting frame supporting module 20 to drive the lifting frame supporting module 20 to lift the lifting frame supporting module 20 and the battery cell carrier 50 together relative to the walking frame 10.

[0050] The X-direction adjusting module 40 is arranged at the bottom side of the lifting frame supporting module 20 and is used to adjust the module for loading battery cells in the battery cell carrier 50 in the X-direction.

[0051] It should be noted that the battery cell carrier 50 is used to load a plurality of battery cells at one time, and the module for loading battery cells has a movable freedom in the X-direction to be able to switch between an expanded state and a contracted state. The module for loading battery cells in the battery cell carrier 50 can place battery cells in the expanded state, and can fix the loaded battery cells to avoid shaking of the battery cells in the contracted state.

[0052] In the embodiment, the walking frame 10 is movably connected to the crane rail 200 to realize movement of the entire battery cell carrier handling crane 100 relative to the crane rail 200, i.e., the battery cell carrier handling crane 100 has a movable freedom in the Y-direction.

[0053] The lifting frame supporting module 20 is used to support the battery cell carrier 50 and is movably connected to the lifting drive mechanism 30 to have a movable freedom in the Z-direction under the drive of the lifting drive mechanism 30. Moreover, the X-direction adjusting module 40 can adjust the module for loading battery cells in the battery cell carrier 50 in the X-direction to switch the state of the module for loading battery cells in the battery cell carrier 50.

[0054] In specific applications, after the battery cell carrier 50 is filled with battery cells, the battery cell carrier handling crane 100 in the transplanting device can move to the upper side of the battery cell carrier 50. The lifting frame supporting module 20 in the battery cell carrier handling crane 100 falls under the action of the lifting drive mechanism 30 and is connected to the battery cell carrier 50. The X-direction adjusting module 40 is connected to the module for loading battery cells in the battery cell carrier 50.

[0055] It should be noted that in order to load battery cells, the module for loading battery cells in the battery cell carrier 50 is in the expanded state. After being filled with battery cells, the module for loading battery cells in the battery cell carrier 50 is still in the expanded state. After the X-direction adjusting module 40 is connected to the module for loading battery cells in the battery cell carrier 50, the module can be adjusted in the X-direction to switch the module to the contracted state.

[0056] After the module for loading battery cells in the battery cell carrier 50 is in a retracted state, the lifting drive mechanism 30 can drive the lifting frame supporting module 20 to lift the battery cell carrier 50 to a safe position, and then the battery cell carrier transport crane 100 drives the battery cell carrier 50 to move along the crane track 200 to the next workstation.

[0057] During the movement, since the module for loading the battery cells in the battery cell carrier 50 is in a retracted state, the battery cells are fixed to prevent the battery cells from shaking, thereby ensuring safety.

[0058] It can be seen that in the battery carrier transporting overhead crane 100 provided in the present application, the X-axis adjustment module 40 replaces the existing overhead crane's solution of using multiple clamps, and a module for loading battery cells is implemented in the X-axis adjustment battery carrier 50 to switch the state of the module to avoid shaking of the battery cells during transportation, ensure safety during transportation, and reduce costs.

[0059] It should be noted that the battery cell carrier 50 is used to carry airbag-less soft-pack batteries, and the battery cell carrier transport overhead crane 100 can transport multiple airbag-less soft-pack batteries at a time.

[0060] Figure 3 This is a schematic diagram of an X-direction adjustment module 40 provided according to one embodiment of the present application. Figure 3 The X-direction adjustment module 40 includes an X-direction telescopic mechanism 41 and a clamping block structure 42 .

[0061] The block structure 42 is connected to the X-direction telescopic mechanism 41 and is configured to move along the X-direction under the drive of the X-direction telescopic mechanism 41 .

[0062] In this embodiment, the block structure 42 is used to clamp the X-direction side of the module for loading battery cells in the battery carrier 50, and the X-direction telescopic mechanism 41 is used to drive the block structure 42 to move in the X-direction, thereby driving the module for loading battery cells in the battery carrier 50 to move in the X-direction to switch the state of the module.

[0063] Figure 4 for Figure 3 A partial enlarged view of S1 in the figure. Figure 4 In a further optional embodiment, the card block structure 42 includes a fixed guide seat 421 and a card block 422 , and the fixed guide seat 421 includes a fixed block 4211 , a sliding block 4212 , a sliding rail 4213 and an elastic member 4214 .

[0064] The slide rail 4213 is arranged along the X direction, the fixed blocks 4211 are arranged at both ends of the slide rail 4213 along the X direction and connected to the X direction telescopic mechanism 41, the sliding block 4212 is slidingly connected to the slide rail 4213 and located between the fixed blocks 4211 at both ends, and the elastic member 4214 is clamped between the fixed blocks 4211 at both ends and the sliding block 4212. The clamping block 422 is connected to the sliding block 4212 and provided with the clamping groove C.

[0065] In the embodiment, the clamping block structure 42 is composed of at least the fixed guide seat 421 and the clamping block 422, wherein the fixed guide seat 421 is composed of at least the fixed block 4211, the sliding block 4212, the slide rail 4213 and the elastic member 4214.

[0066] The clamping block 422 is connected to the sliding block 4212 in the fixed guide seat 421 and formed with the clamping groove C, which can be clamped to the module for loading the battery cell in the battery cell carrier 50.

[0067] In addition, since the sliding block 4212 is slidingly connected to the slide rail 4213, the clamping block 422 has the moving freedom along the X direction, and the elastic member 4214 clamped between the fixed block 4211 and the sliding block 4212 can make the sliding block 4212 in the appropriate position.

[0068] It should be understood that, in the process of carrying the battery cell carrier 50, the battery cell carrier 50 is difficult to avoid slight shaking, since the clamping block 422 has the moving freedom along the X direction and under the action of the elastic member 4214, the battery cell carrier 50 can buffer the direct impact on the clamping block 422 when slight shaking occurs, and the clamping block 422 can reset under the action of the elastic member 4214 after being impacted, so as to ensure that the module for loading the battery cell in the battery cell carrier 50 maintains the retracted state as much as possible.

[0069] In a further optional embodiment, the clamping block structure 42 further comprises a second detection switch 423 arranged on both sides of the clamping groove C along the X direction.

[0070] In the embodiment, after the clamping block 422 is clamped to the module for loading the battery cell in the battery cell carrier 50, the second detection switch 423 can send a corresponding switching signal to confirm that the clamping block 422 is clamped in place, so as to perform the next switching state action.

[0071] In Figure 3 In the embodiment, the X direction telescopic mechanism 41 is a linear driving mechanism based on a lead screw. Specifically, the X direction telescopic mechanism 41 comprises an X direction driving device 411, an X direction driving transmission belt module 412, an X direction lead screw 413, an X direction guide rod 414 and an X direction telescopic rod 415.

[0072] The X guide rods 414 are located on both sides of the Y direction of the X direction lead screw 413, and the X direction driving device 411 is connected to the X direction lead screw 413 through the X direction driving transmission belt module 412 and can drive the X direction lead screw 413 to rotate.

[0073] The X direction telescopic rod 415 is rotationally connected to the X direction lead screw 413 and is slidingly connected to the X direction guide rod 414. The X direction driving device 411 drives the X direction driving transmission belt module 412 to drive the X direction lead screw 413 to rotate, so that the X direction telescopic rod 415 moves along the X direction lead screw 413 and the X direction guide rod 414, thereby driving the clamping block structure 42 to move in the X direction.

[0074] It should be noted that the X direction telescopic mechanism 41 is not limited to Figure 3 In the illustrated embodiment, for example, a linear motor, an electric telescopic rod, an electric cylinder, etc. can also be used, as long as it can provide the clamping block structure 42 with X direction freedom.

[0075] Figure 5 In order to Figure 1 A schematic view of the lifting frame supporting module 20. Please refer to Figure 5 The lifting frame supporting module 20 includes a lifting frame 21, a Y direction expansion and contraction mechanism 22, and a movable supporting plate set 23.

[0076] The Y direction expansion and contraction mechanism 22 is arranged on the lifting frame 21, and the movable supporting plate set 23 is movably connected to the lifting frame 21 and the Y direction expansion and contraction mechanism 22, so as to move in the Y direction under the driving of the Y direction expansion and contraction mechanism 22. The X direction both ends of the movable supporting plate set 23 extend out of the lifting frame 21 and are used to support the battery cell carrier 50

[0077] In the embodiment, the lifting frame supporting module 20 at least has the lifting frame 21, the Y direction expansion and contraction mechanism 22, and the movable supporting plate set 23.

[0078] The Y direction expansion and contraction mechanism 22 is fixedly installed on the lifting frame 21, and the movable supporting plate set 23 is movably connected to the Y direction expansion and contraction mechanism 22 and the lifting frame 21. The Y direction expansion and contraction mechanism 22 can drive the movable supporting plate set 23 to move in the Y direction, so that the X direction both ends of the movable supporting plate set 23 can be matched with the battery cell carrier 50.

[0079] In the case that the movable supporting plate set 23 is matched with the battery cell carrier 50, the lifting frame 21 is driven to lift by the lifting driving mechanism 30, so that the movable supporting plate set 23 drives the battery cell carrier 50 to lift together.

[0080] In a further optional embodiment, the lifting frame 21 includes an upper plate 211, a lower plate 212, a lifting lead screw 213, and a plurality of guide rods 214.

[0081] The upper plate 211 and the lower plate 212 are spaced apart in the Z direction, and a plurality of guide rods 214 are connected between the upper plate 211 and the lower plate 212 and are in sliding connection with the walking frame 10.

[0082] The Y direction expansion and contraction mechanism 22, the movable supporting plate group 23, and the X direction adjustment module 40 are all located on the lower plate 212. The lifting screw rod 213 is rotationally connected between the upper plate 211 and the lower plate 212 and is in rotational connection with the walking frame 10. The lifting drive mechanism 30 is connected to the lifting screw rod 213 to drive the rotation of the lifting screw rod 213, and the lifting frame 21 is lifted.

[0083] In this embodiment, the lifting frame 21 is a frame structure assembled by the upper plate 211, the lower plate 212, the lifting screw rod 213, and a plurality of guide rods 214, wherein the lifting screw rod 213 and the plurality of guide rods 214 are installed between the upper plate 211 and the lower plate 212. The lifting frame 21 is movably connected to the walking frame 10 through the lifting screw rod 213 and the plurality of guide rods 214, wherein the lifting screw rod 213 is in rotational connection with the walking frame 10, and the guide rods 214 are in sliding connection with the walking frame 10.

[0084] In addition, the Y direction expansion and contraction mechanism 22, the movable supporting plate group 23, and the X direction adjustment module 40 are all installed on the lower plate 212, and the movable supporting plate group 23 is connected to the Y direction expansion and contraction mechanism 22.

[0085] Secondly, the lifting screw rod 213 is rotated under the drive of the lifting drive mechanism 30, and the lifting screw rod 213 converts the rotary motion into the lifting motion of the lifting frame 21. Moreover, due to the guiding effect of the plurality of guide rods 214, the stability of the lifting frame 21 during the lifting process is ensured.

[0086] In a further optional embodiment, the movable supporting plate group 23 is arranged on the Y direction two sides of the lower plate 212 and is movably connected to the lower plate 212, and the Y direction expansion and contraction mechanism 22 can drive the Y direction two movable supporting plate groups 23 to approach or move away from each other in the Y direction.

[0087] In this embodiment, the number of the movable supporting plate groups 23 is two, and both of the movable supporting plate groups 23 are movably connected to the lower plate 212 and are respectively located on the Y direction two sides of the lower plate 212.

[0088] The two movable supporting plate groups 23 are driven by the Y direction expansion and contraction mechanism 22 to approach or move away from each other in the Y direction, that is, to realize the expansion and contraction of the two movable supporting plate groups 23 in the Y direction.

[0089] In specific applications, when it is necessary to carry the battery cell carrier 50, the two movable supporting plate groups 23 are expanded; and after the carrying of the battery cell carrier 50 is completed, the two movable supporting plate groups 23 are retracted.

[0090] Figure 6 ToFigure 5 a local enlarged view of S2 in FIG. 2. Please refer to Figure 6 The Y-direction expansion mechanism 22 comprises a Y-direction driving device 221, a Y-direction expansion transmission belt module 222, and a Y-direction expansion bidirectional screw rod 223.

[0091] The Y-direction expansion mechanism 22 is arranged at the middle position of the lower plate 212, the Y-direction driving device 221 is fixedly installed on the lower plate 212 and can drive the Y-direction expansion bidirectional screw rod 223 to rotate through the Y-direction expansion transmission belt module 222, and the Y-direction expansion bidirectional screw rod 223 can convert the rotation into the Y-direction linear motion of the movable support plate set 23.

[0092] It should be noted that the bidirectional screw rod is a screw rod on which two threads with different rotation directions are formed, that is, one right-handed thread and one left-handed thread. The movable support plate sets 23 on both sides are rotationally connected with the two thread segments with different rotation directions, and the Y-direction expansion bidirectional screw rod 223 is driven by the Y-direction driving device 221 and the Y-direction expansion transmission belt module 222 to realize the synchronization of the movable support plate sets 23 on both sides to move close to or away from each other in the Y-direction.

[0093] In addition, in order to ensure the reliability of the movement of the movable support plate sets 23 on both sides, the Y-direction guide rail sliding block mechanisms 24 are arranged at the X-direction two ends of the lower plate 212 to be slidingly connected with the movable support plate sets 23 on both sides, so as to ensure that the movable support plate sets 23 on both sides maintain translational motion as much as possible during the movement.

[0094] In Figure 5 and Figure 6 the embodiment shown, the Y-direction expansion mechanism 22 is a linear mechanism based on a bidirectional screw rod. Of course, the Y-direction expansion mechanism 22 is not limited to this, for example, a cooperation mechanism of two linear motors can also be used to ensure that the movable support plate sets 23 on both sides can move close to or away from each other.

[0095] Please refer to Figure 5 In some optional embodiments, the lifting screw rod 213 is arranged at the middle position of the upper plate 211 and the lower plate 212.

[0096] In the embodiment, the lifting screw rod 213 is a main lifting transmission component, and the lifting screw rod 213 is arranged at the middle position of the lifting frame 21, so as to ensure that the lifting frame 21 maintains translational motion as much as possible during the lifting process, thereby avoiding the uneven bearing of the plurality of guide rods 214 and prolonging the service life.
