[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0034] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0035] After welding and other processes, the battery module needs to be flipped 180 degrees and moved to a new pallet. Since the battery module is relatively heavy, in order to ensure the stability of the flipping process, the relevant technology usually uses diagonal braces, multiple sets of fasteners and other structures to fix the flipping equipment to the work site, and the flipping equipment takes up a lot of space.

[0036] Therefore, based on the above considerations, in order to reduce the space occupied by the flipping device, the present application proposes a flipping device. When in use, the flipping device has a higher structural stability, the lifting mechanism is more stable, and the flipping is more stable, and they can promote each other, and can reduce the diagonal brace and other structures required when the equipment frame is connected to the work site, and has a higher structural compactness, which can reduce the space occupied.

[0037] Next, the structure of the flipping device proposed in the present application is explained with a specific embodiment.

[0038] In one embodiment of the present application, refer to Figure 1 , Figure 2 , Figure 3 and Figure 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 beside a conveyor line 160; the conveyor line 160 is used to convey a to-be-flipped object 200, the to-be-flipped object 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 a second supporting member 300 to the to-be-flipped object 200 after the to-be-flipped object 200 is lifted. 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, and the first clamping mechanism 140 is used to clamp the first supporting member 210; the second clamping mechanism 150 is arranged 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.

[0039] 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 by fasteners such as bolts. The conveyor line 160 can be set as a conveyor belt or a conveyor roller, wherein the conveyor line 160 can be set to convey along the X direction in the figure, including conveying the above-mentioned flipped member 200, the second supporting member 300, etc.; when the conveyor line 160 is set as a conveyor roller, the rollers can be set at intervals. At least part of the equipment rack 110 is used to be set beside the conveyor line 160, which can be understood as the equipment rack 110 is not suspended above the conveyor line 160. For example, the connecting columns 113 of the equipment rack 110 can be set beside the conveyor line 160, for example, the connecting columns 113 are set beside the conveyor line 160 in the direction Y in the figure; or the connecting columns 113 are passed through the conveyor line 160 with intervals, such as through the intervals between the above-mentioned conveyor rollers, to further improve the space utilization. In this case, it can be understood that part of the equipment rack 110 is set beside part of the conveyor line 160.

[0040] The lifting mechanism 120 can be understood as a mechanism that can be lifted and lowered relative to the equipment rack 110, for example, relatively lifted and lowered 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, which are not limited in this embodiment. 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 be clamped, such as mechanisms such as clamps. 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.

[0041] Reference Figure 5 The flipping device also includes a counterweight structure 171 and a flexible connector 172, 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 frame 110.

[0042] The counterweight structure 171 can be set as a counterweight block, etc., and the flexible connector 172 can be set as a rope, a connecting belt, etc. 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, 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.

[0043] 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 .

[0044] Reference 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. The two ends of the connecting column 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 column 113 form a through space 101, and part of the upper connecting frame 111 abuts against the flexible connector 172.

[0045] The upper connection frame 111 can be understood as a hollow connection structure located on the upper side, the lower connection frame 112 can be understood as a hollow connection structure located on the lower side, and the connecting column 113 can be understood as an overall relatively upright column connecting the upper connection frame 111 and the lower connection frame 112 .

[0046] The equipment frame 110 includes an upper connection frame 111, a lower connection frame 112 and at least two connection 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 space utilization of the flipping equipment.

[0047] The flip mechanism 130 is configured to flip the raised to-be-flipped member 200 along a first rotation direction; the flip mechanism 130 is also configured to flip the raised first supporting member 210 along a second rotation direction after the second supporting member 300 carries the battery module 220, and the second rotation direction is opposite to the first rotation direction. For example, the first rotation direction can be set to a clockwise direction, and the second rotation direction can be set to a counterclockwise direction.

[0048] When the flipping device in the technical solution of the present application is in use, the device frame 110 includes an upper connection frame 111, a lower connection frame 112 and at least two connection columns 113, and thus has a high structural stability. The device frame 110 is also conducive to stably bearing the heavy counterweight structure 171, and is conducive to forming a through space 101 to accommodate the lifting mechanism 120, the flipping mechanism 130, the first clamping mechanism 140 and the second clamping mechanism 150 to improve the compactness of the structure. The two ends of the flexible connector 172 are respectively connected to the counterweight structure 171 and the lifting mechanism 120, which is conducive to reducing the power variation amplitude of the power source corresponding to the lifting mechanism 120, so that the lifting and lowering of the lifting mechanism 120 is more stable. The flipping mechanism 130 is configured to flip and raise the to-be-flipped member 200 along a first rotation direction, and is also configured to flip and raise the first supporting member 210 along a second rotation direction after the second supporting member 300 carries the battery module 220. The second rotation direction is opposite to the first rotation 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 frame 110 itself has a higher structural stability, the lifting mechanism 120 is more stable in lifting and lowering, and the flipping mechanism 130 is more stable in flipping and can promote each other, reducing the diagonal brace and other structures required when the equipment frame 110 is connected to the work site, and it itself has a higher structural compactness, reducing the occupied space. In addition, at least part of the equipment frame 110 is used to be arranged beside the conveyor line 160, which is also beneficial to reduce the space occupied by the flipping equipment and to improve the process connection efficiency of conveying the battery module 220 and flipping the battery module 220; the flipping equipment can first lift and then flip the to-be-flipped part 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 to-be-flipped part 200 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 flip and reset 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 improve the flipping efficiency.

[0049] Specifically, when the flipping device is used, 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 through the conveyor line 160; the first supporting piece 210 and the battery module 220 can be clamped respectively through the first clamping mechanism 140 and the second clamping mechanism 150; the to-be-flipped piece 200 is then raised to a preset height through the lifting mechanism 120, and the to-be-flipped piece 200 is flipped 180 degrees through 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 are lowered through the lifting mechanism 120, and the battery module 220 can be placed on the bottom through 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 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.

[0050] Among them, each process including conveying the member 200 to be flipped to a preset position, clamping the first supporting member 210 and the battery module 220, raising the member 200 to be flipped to a preset height, flipping the member 200 to be flipped, lowering the first supporting member 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, rising of the first supporting member 210 after the battery module 220 is detached, flipping and resetting of the first supporting member 210 after the battery module 220 is detached, releasing the clamping of the first supporting member 210 by the first clamping mechanism 140, and conveying the first supporting member 210 after the battery module 220 is detached by the conveyor line 160, etc., 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.

[0051] In some embodiments, reference 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 rotatably connected to the lifting mechanism 120 respectively. The rotation axis of the flipping driving mechanism 131 is colinear 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 arranged on the axis A in the figure.

[0052] The flip driving mechanism 131 can be understood as a mechanism that can drive the flipping mechanism 130 to flip; the flip driving mechanism 131 is configured as a driving motor, a driving 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 flip driving mechanism 131 and the driven mechanism 132 are respectively connected to the lifting mechanism 120 for rotation, and it can be understood that at least part of the flip driving mechanism 131 and at least part of the driven mechanism 132 can rotate relative to the lifting mechanism 120.

[0053] In this embodiment, the flipping mechanism 130 includes a flipping driving mechanism 131 and a driven mechanism 132 which are arranged at intervals, thereby increasing the flipping support points of the flipping mechanism 130 and facilitating improving the stability of the flipping mechanism 130 when flipping.

[0054] In some embodiments, reference 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 a 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; 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.

[0055] 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.

[0056] 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 improve the clamping stability of the first supporting member 210 .

[0057] In some embodiments, the second clamping mechanism 150 includes a third clamping assembly 151 and a fourth clamping assembly 152 , and 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 .

[0058] The third clamping assembly 151 and the fourth clamping assembly 152 included in the second clamping mechanism 150 can be understood as assemblies for clamping the battery module 220 respectively.

[0059] In this embodiment, the third clamping assembly 151 and the fourth clamping assembly 152 can increase the clamping points for the battery module 220 , which is beneficial to improving the clamping stability of the battery module 220 .

[0060] In some embodiments, reference Figure 1 and Figure 5 The equipment frame 110 is provided with a rack 122, which is extended in the up-down direction; the lifting mechanism 120 includes a lifting drive device 121 and a gear, the output shaft of the lifting drive device 121 is connected to the gear, and the gear is meshed with the rack 122. Figure 1 and Figure 5 The turning device is provided with two sets of racks 122, gears and a lifting drive device 121.

[0061] The rack 122 is extended in the up-down direction, which can be understood as the length direction of the rack 122 is arranged in the up-down direction, and the connecting teeth of the rack 122 are arranged in sequence in the up-down direction. The lifting drive device 121 can be understood as a device that outputs the power required for lifting when the lifting mechanism 120 is lifted. The lifting drive device 121 can be set as a rotating motor or other device.

[0062] 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 arranged on the equipment mechanism 110 and the gear is arranged 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.

[0063] In some embodiments, reference Figure 1 The flipping device also includes a conveyor line 160; the equipment rack 110 has a through space 101 that penetrates the equipment rack 110 in a horizontal direction, for example, the through space 101 penetrates 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.

[0064] The through-space 101 may be understood as a space that passes through the equipment rack 110. The conveyor line 160 passes through the through-space 101, which may be understood as two ends of the conveyor line 160 extending out of the through-space 101, respectively.

[0065] In this embodiment, the conveyor line 160 passes through the through space 101 in a horizontal direction, so that the battery module 220 can be turned over inside the turning device and transferred from the first supporting member 210 to the second supporting member 220, thereby reducing the overall footprint of the turning and transferring process.

[0066] In some embodiments, reference Figure 6 The flipping device also includes a blocking mechanism 161, which is used to block the to-be-flipped member 200 located on the conveying line 160 or to block the second supporting member 300 located on the conveying line 160. The blocking mechanism 161 can be raised and lowered relative to the conveying line 160.

[0067] 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 to-be-flipped part 200 or the second supporting part 300 located on the conveyor line 160 by extending out of the upper surface of the conveyor line 160, and allow the second supporting part 300 and other structures to pass through by retracting to below the upper surface of the conveyor line 160.

[0068] 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 a 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.

[0069] Correspondingly, the present application also proposes a method for using a flip device, and the method is applied to the flip device. Figure 7 , the method of use comprises the following steps: Step S110, clamping the to-be-turned object 200 by the first clamping mechanism 140 and the second clamping mechanism 150; Step S120, raising the to-be-turned object 200 by the lifting mechanism 120; Step S130, using the flipping mechanism 130 to flip the lifted to-be-flipped member 200 along the first rotation direction; Step S140, placing a second supporting member 300 below the raised object to be flipped 200, for example, placing the second supporting member 300 on the conveying line 160; Step S150, lowering the battery module 220 relative to the second supporting member 300 through the lifting mechanism 120; Step S160 , 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 carries the battery module 220 ; After the step of 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 carries the battery module 220, the method of use further includes the following steps: Step S170, raising the first supporting member 210 through the lifting mechanism 120; Step S180, flipping the raised first supporting member 210 along a second rotation direction through the flipping mechanism 130, the second rotation direction being opposite to the first rotation direction; for example, the first rotation direction may be set to a clockwise direction, and the second rotation direction may be set to a counterclockwise direction; In step S190 , the inverted first supporting member 210 is lowered by the lifting mechanism 120 .

[0070] When the flipping device is used by the method of the present application, the flipped member 200 to be flipped is flipped along the first rotation direction, and the first supporting member 210 to be flipped is flipped 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 conducive to reducing the diagonal brace and other structures required when the corresponding equipment rack 110 is connected to the work site, and is conducive to reducing the occupied space. In addition, the flipping device can first lift and then flip the flipped member 200 containing the battery module 220 through the lifting mechanism 120 and the flipping mechanism 130, which is conducive to reducing the risk of the flipped member 200 colliding with the equipment rack 110 or the conveyor line 160 during the flipping process; the first clamping mechanism 140 is maintained to clamp the first supporting member 210 and the second clamping mechanism 150 is released to clamp the battery module 220, which is conducive 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 conducive to improving the flipping efficiency.

[0071] After the battery module 220 is detached, the first supporting member 210 can be turned over and reset, and the first supporting member 210 can continue to be used to carry a new battery module 220 , which is also beneficial to improving the use efficiency of the first supporting member 210 .

[0072] The second rotation direction is opposite to the first rotation direction, which is also beneficial to reducing the cumulative error of the flipping process and improving the repeated position accuracy of the flipping process.

[0073] In some embodiments, reference Figure 8 The step of lowering the battery module 220 relative to the second supporting member 300 includes: The battery module 220 and the first supporting member 210 are synchronously lowered relative to the second supporting member 300 .

[0074] In this embodiment, the battery module 220 and the first supporting member 210 are synchronously lowered 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 .

[0075] The present application also proposes a method for flipping a battery module, referring to Fig. 9 The flipping method of the above flipping device comprises the following steps: Step S210, placing the battery module 220 on the first supporting member 210, the first supporting member 210 and the battery module 220 form the to-be-turned member 200; Step S220, clamping the to-be-turned part 200, Step S230, raising the to-be-turned member 200; Step S240, turning over the raised part 200 to be turned over; Step S250, placing a second supporting member 300 below the raised member to be flipped 200; Step S260, lowering the battery module 220 relative to the second supporting member 300; Step S270 , 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 220 .

[0076] When the flipping battery module 220 is used by the flipping method of the present application, it is helpful to reduce the risk of unstable flipping caused by pipeline entanglement, and it is helpful to reduce the diagonal brace and other structures required when the corresponding equipment rack 110 is connected to the work site, which is helpful to reduce 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 is conducive 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 conducive to improving the flipping efficiency.
