When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0068] After welding and other processes, the battery module needs to be flipped 180 degrees and transferred to a new pallet. In the related art, the flipping process of the flipping equipment is relatively complicated and the flipping efficiency needs to be improved.

[0069] Therefore, based on the above considerations, and in order to improve flipping efficiency, the present application proposes a flipping device. When in use, the flipping device enables the second clamping mechanism to release the clamping of the battery module independently of the first clamping mechanism, which is beneficial for flipping and resetting the first support member while the battery module and the second support member are conveyed through the conveyor line, thereby improving flipping efficiency.

[0070] Next, the structure of the flip device proposed in this application is explained with a specific embodiment.

[0071] In one embodiment of the present application, referring to Figures 1, 2, 3 and 4, the flipping device includes an equipment frame 110, a lifting mechanism 120, a flipping mechanism 130, a first clamping mechanism 140 and a second clamping mechanism 150, at least part of the equipment frame 110 is used to be arranged next to the conveyor line 160; the conveyor line 160 is used to convey the to-be-flipped member 200, the to-be-flipped member 200 includes a first supporting member 210 and a battery module 220 placed on the first supporting member 210, and the conveyor line 160 is also used to convey the second supporting member 300 to the bottom of the to-be-flipped member 200 after the to-be-flipped member 200 is raised; the lifting mechanism 120 can be lifted and lowered relative to the equipment frame 110; the flipping mechanism 130 is rotatably connected to the lifting mechanism 120; the first clamping mechanism 140 is arranged on the flipping mechanism 130 The first clamping mechanism 140 is used to clamp the first supporting member 210; the second clamping mechanism 150 is provided on the flipping mechanism 130, and the second clamping mechanism 150 is used to clamp the battery module 220, and the second clamping mechanism 150 is used to release the clamping of the battery module 220 independently of the first clamping mechanism 140.

[0072] The equipment rack 110 can be understood as a rack structure for connecting to the work site. For example, the equipment rack 110 can be connected to the work site via fasteners such as bolts. The conveyor line 160 can be configured as a conveyor belt or conveyor rollers. The conveyor line 160 can be configured to convey along the X direction in the figure, including conveying the aforementioned to-be-turned object 200, the second supporting member 300, etc.; when the conveyor line 160 is configured as conveyor rollers, the rollers can be spaced apart. At least part of the equipment rack 110 is used to be set beside the conveyor line 160. It can be understood that the equipment rack 110 is not suspended above the conveyor line 160. For example, the connecting column 113 of the equipment rack 110 can be set beside the conveyor line 160, for example, the connecting column 113 is set beside the conveyor line 160 in the direction Y in the figure; or the connecting column 113 is passed through the conveyor line 160 with a gap, for example, through the gap between the above-mentioned conveyor rollers, to further improve space utilization. At this time, it can be understood that part of the equipment rack 110 is set beside part of the conveyor line 160.

[0073] The lifting mechanism 120 can be understood as a mechanism that can be lifted and lowered relative to the equipment rack 110, for example, relative lifting and lowering along the direction Z in the figure; wherein the lifting mechanism 120 can be lifted and lowered relative to the equipment rack 110 by a gear rack mechanism, a worm gear mechanism, a rope and other mechanisms, and this embodiment does not limit this. The flipping mechanism 130 can be understood as a mechanism that can be flipped by being connected to the lifting mechanism 120 through rotation. The first clamping mechanism 140 and the second clamping mechanism 150 can be understood as mechanisms that can clamp, such as mechanisms such as claws. The first supporting member 210 and the second supporting member 300 can be understood as structural members that can support the battery module 220, for example, they can be set as structures such as trays or accompanying clamps.

[0074] When the flipping device in the technical solution of the present application is in use, at least part of the equipment frame 110 is used to be set next to the conveyor line 160, which is beneficial to reducing the space occupied by the flipping device and improving the process connection efficiency of conveying the battery module 220 and flipping the battery module 220; the flipping device can first lift and then flip the part 200 to be flipped containing the battery module 220 through the lifting mechanism 120 and the flipping mechanism 130, which is beneficial to reducing the risk of the part 200 to be flipped colliding with the equipment frame 110 or the conveyor line 160 during the flipping process; the second clamping mechanism 150 is used to release the clamping of the battery module 200 independently of the first clamping mechanism 140, which is beneficial to flipping and resetting the first supporting member 210 while conveying the battery module 220 and the second supporting member 300 through the conveyor line 160, which is beneficial to improving the flipping efficiency.

[0075] Specifically, when using the flipping device, the to-be-flipped piece 200 including the first supporting piece 210 and the battery module 220 can be first conveyed to a preset position by the conveyor line 160; the first supporting piece 210 and the battery module 220 can be clamped respectively by the first clamping mechanism 140 and the second clamping mechanism 150; the to-be-flipped piece 200 can be raised to a preset height by the lifting mechanism 120, and the to-be-flipped piece 200 can be flipped 180 degrees by the flipping mechanism 130, so that the first supporting piece 210 is on the top and the battery module 220 is on the bottom; after flipping, the first supporting piece 210 and the battery module 220 can be lowered by the lifting mechanism 120, and the battery module 220 can be lowered by the conveyor line 160. The line 160 transports the second supporting member 300 to support the descending battery module 220 through the second supporting member 300; then the second clamping mechanism 150 releases the clamping of the battery module 220 independently of the first clamping mechanism 140, and the battery module 220 can be supported on the second supporting member 300 and output along with the second supporting member 300 through the conveyor line 160; at the same time, the first supporting member 210 clamped by the first clamping mechanism 140 can pass through the lifting mechanism 120 and the flipping mechanism 130, and sequentially perform the processes of rising, flipping and resetting, and descending to the conveyor line 160, so that the first supporting member 210 can flow out of the conveyor line 160 and be used to support a new battery module 220.

[0076] Among them, the various processes such as conveying the part 200 to be flipped to a preset position, clamping the first supporting part 210 and the battery module 220, raising the part 200 to be flipped to a preset height, flipping the part 200 to be flipped, lowering the first supporting part 210 and the battery module 220, releasing the clamping of the battery module 220 by the second clamping mechanism 150 independently of the first clamping mechanism 140, outputting the battery module 220 through the conveyor line 160, raising the first supporting part 210 after the battery module 220 is detached, flipping and resetting the first supporting part 210 after the battery module 220 is detached, releasing the clamping of the first supporting part 210 by the first clamping mechanism 140, and conveying the first supporting part 210 after the battery module 220 is detached by the conveyor line 160, can be connected by a preset timing, that is, each process is executed sequentially at a preset time interval to reduce the use of sensors and reduce the overall material cost of the flipping equipment.

[0077] In some embodiments, referring to Figure 4, the flipping mechanism 130 includes a flipping driving mechanism 131 and a driven mechanism 132 that are spaced apart. For example, the flipping driving mechanism 131 and the driven mechanism 132 are spaced apart along the direction Y in the figure; the flipping driving mechanism 131 and the driven mechanism 132 are respectively rotatably connected to the lifting mechanism 120, and the rotation axis of the flipping driving mechanism 131 is collinear with the rotation axis of the driven mechanism 132. For example, the rotation axis of the flipping driving mechanism 131 and the rotation axis of the driven mechanism 132 are both set on the axis A in the figure.

[0078] The flipping drive mechanism 131 can be understood as a mechanism that can drive the flipping mechanism 130 to flip; the flipping drive mechanism 131 is configured as a drive motor, a drive cylinder, etc., and drives the flipping mechanism 130 to flip through gear meshing, rope transmission, etc. The driven mechanism 132 can be understood as a mechanism that is driven when the flipping mechanism 130 flips, so as to improve the flipping smoothness of the flipping mechanism 130. Among them, the driven mechanism 132 is usually not provided with a power output mechanism to reduce the component cost of the flipping mechanism 130. The flipping drive mechanism 131 and the driven mechanism 132 are respectively connected to the lifting mechanism 120 for rotation. It can be understood that at least part of the flipping drive mechanism 131 and at least part of the driven mechanism 132 can rotate relative to the lifting mechanism 120.

[0079] In this embodiment, the flipping mechanism 130 includes a flipping driving mechanism 131 and a driven mechanism 132 that are spaced apart, which increases the flipping support points of the flipping mechanism 130 and helps improve the stability of the flipping mechanism 130 during flipping.

[0080] In some embodiments, referring to Figure 4, the first clamping mechanism 140 includes a first clamping component 141 and a second clamping component 142. The first clamping component 141 and the second clamping component 142 are spaced apart along the first direction Z. The first direction Z is parallel to the flipping plane of the flipping mechanism 130. The flipping plane can be set to the plane where the rotation direction U in the figure is located. It can be understood that the flipping plane is set to the plane where the rotation direction of the flipping mechanism 130 is located; the first clamping component 141 and the second clamping component 142 are respectively used to clamp the first supporting member 210 on opposite sides along the height direction.

[0081] The first clamping assembly 141 and the second clamping assembly 142 included in the first clamping mechanism 140 can be understood as assemblies for clamping the first supporting member 210 respectively.

[0082] In this embodiment, the first clamping assembly 141 and the second clamping assembly 142 can be used to clamp the first supporting member 210 at two opposite sides along the height direction, which is beneficial to improving the clamping stability of the first supporting member 210 .

[0083] In some embodiments, the second clamping mechanism 150 includes a third clamping assembly 151 and a fourth clamping assembly 152 . The third clamping assembly 151 and the fourth clamping assembly 152 are arranged along a second direction Y, and the second direction Y is parallel to the flip axis A of the flip mechanism 130 .

[0084] The third clamping assembly 151 and the fourth clamping assembly 152 included in the second clamping mechanism 150 can be understood as components for clamping the battery module 220 respectively.

[0085] In this embodiment, the third clamping assembly 151 and the fourth clamping assembly 152 can increase the clamping points on the battery module 220 , which is beneficial for improving the clamping stability of the battery module 220 .

[0086] In some embodiments, referring to FIG. 1 , the equipment frame 110 is provided with a rack 122 extending in the vertical direction. Referring to FIG. 1 and FIG. 5 , the lifting mechanism 120 includes a lifting drive 121 and a gear. The output shaft of the lifting drive 121 is connected to the gear, which meshes with the rack 122. The tilting device in FIG. 1 and FIG. 5 includes two sets of racks 122, gears, and lifting drives 121. These two sets of racks 122, gears, and lifting drives 121 are spaced apart to improve lifting stability. The two sets of racks 122, gears, and lifting drives 121 are spaced apart in a direction parallel to the tilting plane of the tilting mechanism 130. This improves force balance between each set of racks 122, gears, and lifting drives 121, thereby increasing the fatigue life of the racks 122, gears, and lifting drives 121 after repeated use. For example, referring to Figures 1 and 4, the flipping plane of the flipping mechanism 130 is parallel to the XZ plane, and the two sets of racks 122, gears and lifting drive devices 121 are spaced apart along the X-axis direction. It can be understood that the two sets of racks 122, gears and lifting drive devices 121 can be further arranged to be arranged in the horizontal direction.

[0087] The rack 122 extends in the vertical direction, which can be understood as the length of the rack 122 being arranged in the vertical direction, and the connecting teeth of the rack 122 are arranged in sequence in the vertical direction. The lifting drive device 121 can be understood as the device that outputs the required lifting power when the lifting mechanism 120 is raised or lowered. The lifting drive device 121 can be configured as a rotary motor or other device.

[0088] In this embodiment, when the lifting drive device 121 outputs power, the lifting mechanism 120 can be lifted and lowered relative to the equipment frame 110 through the engagement of the gear and the rack 122, thereby improving the lifting and lowering stability of the lifting mechanism 120; the rack 122 is set on the equipment mechanism 110 and the gear is set on the lifting mechanism 120, which is beneficial to reducing the weight of the lifting mechanism 120 and reducing the power consumption of the lifting mechanism 120 during lifting.

[0089] Furthermore, the rotation axis A of the flip mechanism 130 is disposed between the two racks 122, and the connecting teeth of the racks 122 extend in a direction parallel to the flip plane of the flip mechanism 130. In this embodiment, while the connecting teeth of the racks extend in a direction perpendicular to the flip plane of the flip mechanism 130, the connecting teeth of the racks 122 extend in a direction parallel to the flip plane of the flip mechanism 130. This allows the connecting teeth adjacent to the rotation axis A of the flip mechanism 130 to bear the flipping torque caused by the flipping of the flip mechanism 130 through their extension direction, further improving the fatigue life of the racks 122, gears, and lift drive 121 under repeated use.

[0090] In some embodiments, referring to FIG1 , the flip drive mechanism 131 is disposed on a side away from the rack 122; furthermore, the driven mechanism 132 is disposed on a side facing the rack 122; it is understood that since the flip drive mechanism 131 is configured as a drive motor, a drive cylinder, etc., its weight is relatively heavier than that of the driven mechanism 132, and it is necessary to connect the drive motor, the drive cylinder, etc. with electrical wires or hydraulic, pneumatic, or other connecting lines. The flip drive mechanism 131 is disposed on a side away from the rack 122, which can be understood as the flip drive mechanism 131 being further away from the rack 122 than the driven mechanism 132. Thus, when the flipped object 200, the flip mechanism 130, and part of the lifting mechanism 120 are raised and lowered by the lifting drive device 121, the gear, and the rack 122, the relatively distant and relatively heavy flip drive mechanism 131 improves the lifting stability and reduces the risk of interference between the connecting wires of the flip drive mechanism 131 and the transmission mechanism such as the rack 112.

[0091] In some embodiments, referring to Figure 1, the flipping device also includes a conveyor line 160; the equipment rack 110 has a through space 101 that passes through the equipment rack 110 in a horizontal direction, for example, the through space 101 passes through the equipment rack 110 along the Y direction in the figure; the conveyor line 160 passes through the through space 101 in a horizontal direction, for example, the conveyor line 160 passes through the through space 101 along the Y direction in the figure; the lifting mechanism 120, the flipping mechanism 130, the first clamping mechanism 140 and the second clamping mechanism 150 are respectively arranged in the through space 101.

[0092] The through-space 101 can be understood as a space that passes through the equipment rack 110. The conveyor line 160 passes through the through-space 101, which can be understood as both ends of the conveyor line 160 extending out of the through-space 101 respectively.

[0093] In this embodiment, the conveyor line 160 passes through the through space 101 in the horizontal direction, so that the battery module 220 can be flipped inside the flipping device and transferred from the first support member 210 to the second support member 220, thereby reducing the overall footprint of the flipping and transferring processes; the lifting mechanism 120, the flipping mechanism 130, the first clamping mechanism 140 and the second clamping mechanism 150 are respectively arranged in the through space 101, which is conducive to improving the compactness of the flipping device.

[0094] In some embodiments, referring to Figure 5, the flipping device also includes a counterweight structure 171 and a flexible connector 172, and the two ends of the flexible connector 172 are respectively connected to the counterweight structure 171 and the lifting mechanism 120; the flexible connector 172 is high in the middle and low at both ends, and at least part of the flexible connector 172 abuts against the upper side of at least part of the equipment rack 110.

[0095] The counterweight structure 171 can be configured as a counterweight block, etc., and the flexible connector 172 can be configured as a rope, a connecting belt, etc. The flexible connector 172 is higher in the middle and lower at both ends, and at least a portion of the flexible connector 172 abuts against at least a portion of the upper side of the equipment rack 110, so that the counterweight structure 171 can offset at least part of the weight of the lifting mechanism 120 and the flip mechanism 130, the first clamping mechanism 140, the second clamping mechanism 15, the first supporting member 210, and the battery module 220 on the lifting mechanism 120.

[0096] In this embodiment, the counterweight structure 171 can reduce the driving torque of the lifting drive device 121 through the flexible connector 172 , which is beneficial to improving the lifting efficiency and lifting stability of the battery module 220 on the lifting mechanism 120 .

[0097] In some embodiments, the counterweight structure 171 and the flexible connector 172 are arranged on the side of the equipment frame 110 where the rack 122 is provided, so that the counterweight structure 171 and the flexible connector 172 are relatively close to the rack 122, thereby reducing the impact torque of the counterweight structure 171 and the flexible connector 172 on the rack 122 when starting to lift, and improving the fatigue life of the rack 122, gears and other transmission structures under multiple uses.

[0098] In some embodiments, referring to Figure 5, the equipment rack 110 includes an upper connecting frame 111, a lower connecting frame 112 and at least two connecting columns 113. The upper connecting frame 111 and the lower connecting frame 112 are arranged opposite to each other in the up and down directions, and the two ends of the connecting columns 113 are respectively connected to the upper connecting frame 111 and the lower connecting frame 112; the upper connecting frame 111, the lower connecting frame 112 and the connecting columns 113 form a through space 101, and part of the upper connecting frame 111 abuts against the flexible connector 172.

[0099] The upper connecting frame 111 can be understood as a hollow connecting structure located on the upper side, the lower connecting frame 112 can be understood as a hollow connecting structure located on the lower side, and the connecting column 113 can be understood as an overall relatively upright column connecting the upper connecting frame 111 and the lower connecting frame 112.

[0100] In this embodiment, the equipment rack 110 includes an upper connecting frame 111, a lower connecting frame 112 and at least two connecting columns 113, which is beneficial to reducing material consumption and can increase activity space for other components such as flexible connectors 172 and conveyor lines 160, which is beneficial to improving the space utilization of the flipping equipment.

[0101] In some embodiments, the flipping mechanism 130 is configured to flip the raised to-be-flipped member 200 in a first rotational direction. The flipping mechanism 130 is further configured to flip the raised first supporting member 210 in a second rotational direction after the second supporting member 300 carries the battery module 220, the second rotational direction being opposite to the first rotational direction. For example, the first rotational direction may be set to clockwise, and the second rotational direction may be set to counterclockwise.

[0102] In this embodiment, the flipping mechanism 130 is configured to flip and raise the to-be-flipped member 200 along a first rotational direction, and is also configured to flip and raise the first supporting member 210 along a second rotational direction after the second supporting member 300 carries the battery module 220. The second rotational direction is opposite to the first rotational direction, which can reduce the risk of entanglement between the connecting pipelines of the first clamping mechanism 140, the second clamping mechanism 150, and other mechanisms and the counterweight structure 171, the lower connecting frame 112, and other structures, thereby reducing the risk of unstable flipping caused by pipeline entanglement. The equipment rack 110 itself has a high structural stability, the lifting mechanism 120 is more stable in lifting, and the flipping mechanism 130 is more stable in flipping, and they can promote each other, reducing the number of structures such as diagonal braces required when connecting the equipment rack 110 to the work site, and the structure itself has a high structural compactness, reducing the occupied space.

[0103] 6 , the flipping device further includes a blocking mechanism 161 for blocking the part to be flipped 200 on the conveyor line 160 or for blocking the second supporting member 300 on the conveyor line 160 . The blocking mechanism 161 can be raised and lowered relative to the conveyor line 160 .

[0104] Among them, the blocking mechanism 161 can be set as a telescopic mechanism such as a telescopic cylinder, an electric telescopic rod, etc., so as to block the part to be flipped 200 or the second supporting member 300 located on the conveyor line 160 by extending out of the upper surface of the conveyor line 160, and allow the second supporting member 300 and other structures to pass through by retracting to below the upper surface of the conveyor line 160.

[0105] In this embodiment, the blocking mechanism 161 can position the part to be flipped 200 or the second supporting member 300 along the conveying direction (for example, direction X in the figure), thereby reducing the risk of the part to be flipped 200 or the second supporting member 300 being conveyed beyond the preset position, which is beneficial to improving the position accuracy of grasping the part to be flipped 200 or placing the battery module 220 on the second supporting member 200.

[0106] Correspondingly, the present application also proposes a method for using a flip device, which is applied to the above-mentioned flip device. Referring to FIG7 , the method includes the following steps:

[0107] Step S110 , clamping the to-be-turned object 200 by the first clamping mechanism 140 and the second clamping mechanism 150 ;

[0108] Step S120 , raising the to-be-turned object 200 by the lifting mechanism 120 ;

[0109] Step S130, flipping the raised member to be flipped 200 by the flipping mechanism 130; specifically, it can be configured to flip the raised member to be flipped 200 along the first rotation direction by the flipping mechanism 130;

[0110] Step S140 , placing the second supporting member 300 below the raised workpiece 200 to be flipped, for example, placing the second supporting member 300 on the conveyor line 160 ;

[0111] Step S150 , lowering the battery module 220 relative to the second supporting member 300 via the lifting mechanism 120 ;

[0112] In step S160 , the first clamping mechanism 140 maintains clamping of the first supporting member 210 and the second clamping mechanism 150 releases clamping of the battery module 220 , so that the second supporting member 300 carries the battery module 220 .

[0113] When the flipping device is used according to the method of the present application, the flipping device can first lift and then flip the part to be flipped 200 containing the battery module 220 through the lifting mechanism 120 and the flipping mechanism 130, which is beneficial to reduce the risk of the part to be flipped 200 colliding with the equipment frame 110 or the conveyor line 160 during the flipping process; maintaining the first clamping mechanism 140 on the first supporting member 210 and releasing the second clamping mechanism 150 on the battery module 220 is beneficial to flipping and resetting the first supporting member 210 while conveying the battery module 220 and the second supporting member 300 through the conveyor line 160, which is beneficial to improving the flipping efficiency.

[0114] In some embodiments, after maintaining the first clamping mechanism 140 on the first supporting member 210 and releasing the second clamping mechanism 150 from the battery module 220 so that the second supporting member 300 supports the battery module 220, the method further includes the following steps, referring to FIG. 7 :

[0115] Step S170 , raising the first supporting member 210 via the lifting mechanism 120 ;

[0116] Step S180: flipping the raised first supporting member 210 along a second rotation direction by the flipping mechanism 130, where the second rotation direction is opposite to the first rotation direction; for example, the first rotation direction may be set to clockwise, and the second rotation direction may be set to counterclockwise;

[0117] In step S190 , the inverted first supporting member 210 is lowered by the lifting mechanism 120 .

[0118] When the flipping device is used according to this method, the member to be flipped 200 is flipped and raised along the first rotation direction, and the first supporting member 210 is flipped and raised along the second rotation direction. The second rotation direction is opposite to the first rotation direction, which can reduce the risk of entanglement of the connecting pipeline, thereby reducing the risk of unstable flipping caused by pipeline entanglement, which is beneficial to reducing the structures such as the diagonal brace required when connecting the corresponding equipment rack 110 to the work site, and is beneficial to reducing the occupied space.

[0119] Furthermore, after the battery module 220 is detached, the first supporting member 210 can be flipped and reset, allowing it to continue to support a new battery module 220, thereby improving the efficiency of the first supporting member 210. Furthermore, the second rotational direction is opposite to the first rotational direction, thereby reducing cumulative errors during the flipping process and improving the repeatability of the flipping process.

[0120] In some embodiments, referring to FIG. 8 , the step of lowering the battery module 220 relative to the second supporting member 300 includes:

[0121] The battery module 220 and the first supporting member 210 are synchronously lowered relative to the second supporting member 300 .

[0122] In this embodiment, the battery module 220 and the first supporting member 210 are lowered synchronously relative to the second supporting member 300 , which helps to reduce the complexity of the process of lowering the battery module 220 and the first supporting member 210 .

[0123] In some embodiments, referring to FIG. 8 , after maintaining the first clamping mechanism 140 clamping the first supporting member 210 and releasing the second clamping mechanism 150 clamping the battery module 220 so that the second supporting member 300 supports the battery module 220 , the method further includes the following steps:

[0124] Raise the first supporting member 210 via the lifting mechanism 120;

[0125] The raised first supporting member 210 is flipped over by the flipping mechanism 130;

[0126] The inverted first supporting member 210 is lowered by the lifting mechanism 120 .

[0127] In this embodiment, after the battery module 220 is detached, the first supporting member 210 can be flipped and reset, and the first supporting member 210 can continue to be used to support a new battery module 220 , which is beneficial to improving the use efficiency of the first supporting member 210 .

[0128] In some embodiments, referring to FIG. 8 , the step of flipping the raised member to be flipped 200 includes: flipping the raised member to be flipped 200 along a first rotation direction;

[0129] The step of flipping the raised first supporting member 210 includes flipping the raised first supporting member 210 along a second rotation direction, the second rotation direction being opposite to the first rotation direction. For example, the first rotation direction may be set to clockwise, and the second rotation direction may be set to counterclockwise.

[0130] In this embodiment, the second rotation direction is opposite to the first rotation direction, which is beneficial to reducing the cumulative error of the flipping process and improving the repeat position accuracy of the flipping process.

[0131] The present application also proposes a flipping method for a battery module. Referring to FIG. 9 , the flipping method can be applied to the above-mentioned flipping device. The flipping method includes the following steps:

[0132] Step S210 , placing the battery module 220 on the first supporting member 210 , so that the first supporting member 210 and the battery module 220 form the to-be-turned member 200 ;

[0133] Step S220: clamp the part 200 to be flipped.

[0134] Step S230, raising the part to be flipped 200;

[0135] Step S240, turning over the raised part 200 to be turned over;

[0136] Step S250, placing a second supporting member 300 below the raised member to be flipped 200;

[0137] Step S260 , lowering the battery module 220 relative to the second supporting member 300 ;

[0138] In step S270 , the first supporting member 210 is kept clamped and the battery module 220 is released, and the second supporting member 300 carries the battery module 220 .

[0139] When using the flipping method of the present application to flip the battery module 220, it is beneficial to reduce the risk of unstable flipping caused by pipeline entanglement, and it is beneficial to reduce the diagonal bracing and other structures required when connecting the corresponding equipment rack 110 to the work site, which is beneficial to reducing the occupied space. In addition, maintaining the clamping of the first supporting member 210 and releasing the clamping of the battery module 220 and allowing the second supporting member 300 to carry the battery module 300 facilitates flipping and resetting the first supporting member 210 while conveying the battery module 220 and the second supporting member 300 via the conveyor line 160, which is beneficial to improving flipping efficiency.
