Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the scope of protection of this application

[0051] As Figures 1 to 4 shown, the embodiment of this application provides a stacking system for a battery module, including: transport vehicle 1, operation station 2, lifting mechanism 3, and clamping opening mechanism 4

[0052] The transport vehicle 1 includes a tray 10. The tray 10 includes a bottom plate 11 and a clamping mechanism 12 disposed on the bottom plate 11. The clamping mechanism 12 includes a first clamping plate 121 and a second clamping plate 122 that are oppositely arranged, and a support seat 120 located between the first clamping plate 121 and the second clamping plate 122. The transport vehicle 1 can be an Automated Guided Vehicle (AGV for short), which is equipped with an automatic navigation device such as electromagnetic or optical, can travel along a specified navigation path, and has safety protection and various transfer functions.

[0053] The operation station 2 includes a movable passage allowing the transport vehicle 1 to enter and exit, and an unclamping platform 20 located at one end of the movable passage. Lifting mechanisms 3 are located on both sides of the movable passage for clamping and lifting the tray 10. An unclamping mechanism 4 is disposed on the unclamping platform 20, and the unclamping mechanism 4 is movably connected to the clamping mechanism 12.

[0054] In the first state, the unclamping mechanism 4 opens the first clamping plate 121 and the second clamping plate 122 to stack the pre-stacked battery modules M in the accommodation space formed between the first clamping plate 121, the second clamping plate 122, and the support seat 120; in the second state, the unclamping mechanism 4 closes the first clamping plate 121 and the second clamping plate 122 to stack the battery modules M. The pre-stacked battery modules M include multiple columns of batteries and battery filling blocks arranged side by side, and the shape of each battery is generally a cuboid.

[0055] As Figures 2 to 4 shown, the clamping mechanism 12 of the tray 10 includes a first clamping plate 121 and a second clamping plate 122 that are oppositely arranged, and a support seat 120 located between the first clamping plate 121 and the second clamping plate 122. In the first state, the unclamping mechanism 4 pushes and pulls the first clamping plate 121 and the second clamping plate 122 apart to stack the pre-stacked battery modules M in the accommodation space formed by the first clamping plate 121, the second clamping plate 122, and the support seat 120; in the second state, the unclamping mechanism 4 closes the first clamping plate 121 and the second clamping plate 122 to stack the battery modules M.

[0056] Optionally, the battery module stacking system provided in the embodiment of the present application further includes an operating robot. The operating robot is disposed adjacent to the operation station 2, and a gripper is provided at the end of the operating robot. The gripper is used to grasp the pre-stacked battery modules M. The operating robot can be a six-axis robot, and a gripper is installed at its end. The gripper includes a plurality of single gripper components, and the number of single gripper components corresponds to the number of battery columns of the battery module M. For example, the pre-stacked battery module M includes 1 column of batteries arranged side by side, the gripper includes 5 single gripper components, and each single gripper component is used to grasp 1 column of batteries, that is, 1 battery module M. The operating robot grasps a plurality of battery modules M through the gripper, replacing manual operation and improving the degree of automation. The specific structure of the gripper is a mature existing design and will not be elaborated here.

[0057] In the embodiment of the present application, the stacking system of the battery module is applied to an automated production line. The automated production line includes a plurality of operating stations. The transport vehicle 1 carries the battery module M on the pallet 10 to load and unload at each operating station, reducing manual operation and improving the assembly efficiency. Among them, after the transport vehicle 1 enters the predetermined position of the moving channel of the stacking operating station 2, the lifting mechanisms 3 located on both sides of the moving channel clamp and lift the pallet 10; then the clamping mechanism 4 on the clamping platform 20 at one end of the moving channel opens the first clamping plate 121 and the second clamping plate 122 of the clamping mechanism 12 of the pallet 10, and the operating robot automatically grabs the pre-stacked battery module M and stacks it in the accommodation space formed between the first clamping plate 121, the second clamping plate 122 and the support seat 120. Then the clamping mechanism 4 closes the first clamping plate 121 and the second clamping plate 122 to stack the battery module M. Then the transport vehicle 1 carries the stacked battery module M into the next operating station. Since the functions of the lifting mechanism 3, the clamping mechanism 4, the pallet 10 of the transport vehicle 1, the operating robot, etc. are highly concentrated, and the production rhythm is roughly the same as that of other operating stations on the automated production line, the degree of automation is relatively high, and a large amount of manpower does not need to be invested. The stacking process of the battery module is simple, which can improve the overall assembly efficiency.

[0058] According to the stacking system of the battery module provided by the embodiment of the present application, it includes a transport vehicle 1 walking in the moving channel of the operating station 2, lifting mechanisms 3 located on both sides of the moving channel, and a clamping platform 20 located at one end of the moving channel. The transport vehicle 1 includes a pallet 10. The pallet 10 includes a bottom plate 11 and a clamping mechanism 12 arranged on the bottom plate 11. The clamping mechanism 12 includes a relatively arranged first clamping plate 121, a second clamping plate 122 and a support seat 120 located between the first clamping plate 121 and the second clamping plate 122; the lifting mechanism 3 is used to clamp and lift the pallet 10; the clamping mechanism 4 is arranged on the clamping platform 20 and is movably connected to the clamping mechanism 12; in the first state, the clamping mechanism 4 opens the clamping mechanism 12 to stack the battery module M in the clamping mechanism 12; in the second state, the clamping mechanism 4 closes the clamping mechanism 12 to stack the battery module M, so that the battery module M can be automatically stacked, the functions of the equipment are highly concentrated, the production efficiency of the production line is effectively improved, and the production cost is reduced.

[0059] The following further describes in detail the specific structures of the various components of the stacking system of the battery module provided by the embodiment of the present application in conjunction with the drawings.

[0060] In some embodiments, the tray 10 further includes a first push-pull mechanism 123 connected to the first clamping plate 121 and a second push-pull mechanism 124 connected to the second clamping plate 122. The clamping mechanism 4 includes a first driving mechanism 41 and a second driving mechanism 42 arranged adjacent to each other. The first driving mechanism 41 can be connected to the first push-pull mechanism 123 to drive the first clamping plate 121 to perform an opening and closing action, and the second driving mechanism 42 can be connected to the second push-pull mechanism 124 to drive the second clamping plate 122 to perform an opening and closing action. The first driving mechanism 41 drives the first clamping plate 121 to perform an opening and closing action through the first push-pull mechanism 123, and the second driving mechanism 42 drives the second clamping plate 122 to perform an opening and closing action through the second push-pull mechanism 124, and the moving directions of the first clamping plate 121 and the second clamping plate 122 are opposite to achieve the opening and closing action.

[0061] Figure 5 Shows Figure 4 Partial enlarged structural schematic diagram of the clamping mechanism in; Figure 6 Shows Figure 4 Partial enlarged structural schematic diagram of the first push-pull mechanism of the tray in, Figure 7 Shows Figure 4 Partial enlarged structural schematic diagram of the claw of the clamping mechanism and the handle of the tray in the first state.

[0062] Such as Figure 5 And Figure 6 As shown in and, the first push-pull mechanism 123 includes: a first guiding component 1231, a first fixing bracket 1232, a first pull rod assembly 1233 and a first elastic component 1234. The first guiding component 1231 is movably connected to the bottom plate 11; one end of the first fixing bracket 1232 is fixedly connected to the slider of the first guiding component 1231, and the other end is fixedly connected to the first clamping plate 121; the first pull rod assembly 1233 includes a first pull rod 1233a fixedly connected to the slider; the first elastic component 1234 is arranged between the two ends of the first fixing bracket 1232 and the bottom plate 11.

[0063] In the first state, the output end of the first driving mechanism 41 drives the first pull rod 1233a to move towards the clamping platform 20 to open the first clamping plate 121. In the second state, the output end of the first driving mechanism 41 is separated from the first pull rod 1233a, and the first pull rod 1233a is reset under the action of the first elastic component 1234.

[0064] Specifically, the first guiding assembly 1231 includes a slide rail and a slider that are slidably connected. The extending direction of the slide rail is the same as the length direction of the first pull rod 1233a, and is used to guide the movement of the first pull rod assembly 1233. The first fixing bracket 1232 includes two parts of brackets. The length and extending direction of the first part of the bracket are substantially the same as those of the first clamping plate 121, and are fixedly connected to the slider. The second part of the bracket is spaced apart from the first part of the bracket and is fixedly connected to the first clamping plate 121. The first elastic assembly 1234 is disposed between the two ends of the first part of the bracket in the length direction and the bottom plate 11. Each first elastic assembly 1234 includes a cylinder, two springs sleeved on the cylinder, and a fixing member between the two springs. The fixing member is connected to one end of the first part of the bracket in the length direction, so that the first pull rod 1233a can automatically reset when performing the closing action, and at the same time, it can buffer the impact force received by the first fixing bracket 1232 driving the first clamping plate 121 during the opening and closing action.

[0065] In some embodiments, the first driving mechanism 41 includes a first power output device and a second power output device that intersect. The first power output device moves along the opening and closing direction of the clamping mechanism 12, and the second power output device moves along the direction perpendicular to the bottom plate 11. The output end of the second power output device is provided with a claw 43. The first pull rod assembly 1233 further includes a handle 1233b connected to the first pull rod 1233a. The first driving mechanism 41 is detachably connected to the handle 1233b through the claw 43.

[0066] As Figures 5 to 7 shown, the claw 43 has degrees of freedom in two directions and can move in two mutually perpendicular directions. In the first state, the claw 43 extends toward the tray 10 under the action of the first power output device and the second power output device, cooperates with the handle 1233b, and then retracts in the direction away from the tray 10 to open the first clamping plate 121; in the second state, the claw 43 disengages from the handle 1233b under the action of the first power output device and the second power output device, and then the first pull rod 1233a drives the handle 1233b to automatically reset under the action of the first elastic assembly 1234 to close the first clamping plate 121.

[0067] In some embodiments, the first power output device includes a first power source 411, a first moving plate 412, and a first bracket 413. The first power source 411 is fixedly connected to the clamping platform 20. The first moving plate 412 is movably connected to the clamping platform 20 along the opening and closing direction. The first bracket 413 is disposed on the first moving plate 412.

[0068] The second power output device includes a second power source 421 and a second bracket 422 connected to the output end of the second power source 421. The second power source 421 is fixedly connected to the first bracket 413. One end of the claw 43 is connected to the second bracket 422, and the other end of the claw 43 extends towards the handle 1233b of the tray 10.

[0069] The first power source 411 and the second power source 421 can be cylinders, hydraulic cylinders, linear motors, etc. A card slot cooperating with the handle 1233b is provided on the claw 43 to prevent the two from disengaging in the first state.

[0070] Furthermore, a pair of third power sources 414 located on both sides of the first bracket 413 are further provided on the first moving plate 412, and third brackets 415 connected to the output ends of each third power source 414. The third brackets 415 are movably connected to the first moving plate 412 along the opening and closing direction, and a guide sleeve 416 is provided on each third bracket 415.

[0071] In the first push-pull mechanism 123, two first pull rods 1233a of the first pull rod assembly 1233 are provided, and the handle 1233b is connected between the two first pull rods 1233a. A first buffer member 1233c is provided on the first pull rod 1233a. The guide sleeve 416 corresponds to the first buffer member 1233c, and in the first state, the guide sleeve 416 and the first buffer member 1233c are in mutual abutting cooperation.

[0072] The third power source 414 can be a cylinder, a hydraulic cylinder, a linear motor, etc. The two guide sleeves 416 located on both sides of the claw 43 in the clamping mechanism 4 and the two first buffer members 1233c located on both sides of the handle 1233b in the tray 10 are arranged in one-to-one correspondence. The first buffer member 1233c can be a spring damper or a hydraulic damper. On the one hand, it can buffer the impact force received by the claw 43 and the handle 1233b during the cooperation process and avoid damaging the components; on the other hand, it can also prevent the claw 43 and the handle 1233b from being unable to cooperate to perform the opening and closing actions of the first clamping plate 121 due to position offset.

[0073] Figure 8 Shown Figure 4 Partial enlarged structural schematic diagram of the second push-pull mechanism of the tray in

[0074] Such as Figure 8As shown, the second push-pull mechanism 124 includes a second guiding component 1241, a second fixed bracket 1242, a second pull rod assembly 1243, and a second elastic component 1244. The second guiding component 1241 is movably connected to the bottom plate 11; one end of the second fixed bracket 1242 is fixedly connected to the slider of the second guiding component 1241, and the other end is fixedly connected to the second clamping plate 122; the second pull rod assembly 1243 includes a second pull rod 1243a fixedly connected to the slider; the second elastic component 1244 is disposed between the two ends of the second fixed bracket 1242 and the bottom plate 11.

[0075] As Figure 5 and Figure 7 shown, the second driving mechanism 42 includes a fourth power source 441 and a second moving plate 442. The fourth power source 441 is fixedly connected to the clamping platform 20, and the second moving plate 442 is movably connected to the clamping platform 20 along the opening and closing direction. In the first state, the second moving plate 442 extends towards the tray 10 and pushes the second pull rod 1243a to open the second clamping plate 122; in the second state, the second moving plate 442 retracts, and the second pull rod 1243a is reset under the action of the second elastic component 1244.

[0076] Specifically, the second guiding component 1241 includes a sliding rail and a slider that are slidably connected. The extending direction of the sliding rail is the same as the length direction of the second pull rod 1243a, and is used to guide the movement of the second pull rod assembly 1243. The second fixed bracket 1242 includes two parts of brackets. The length and extending direction of the first part of the bracket are substantially the same as those of the second clamping plate 122, and are fixedly connected to the slider. The second part of the bracket is spaced apart from the first part of the bracket and is fixedly connected to the second clamping plate 122. The second pull rod assembly 1243 may include two symmetrically arranged second pull rods 1243a to ensure that the second clamping plate 122 is balanced during movement.

[0077] The second elastic component 1244 is disposed between the two ends of the first part of the bracket in the length direction and the bottom plate 11. Each second elastic component 1244 includes a column body, two sections of springs sleeved on the column body, and a fixing member between the two sections of springs. The fixing member is connected to one end of the first part of the bracket in the length direction, so that the second pull rod 1243a can be automatically reset when performing the closing action, and at the same time, the impact force received by the second fixed bracket 1242 driving the second clamping plate 122 during the opening and closing action can be buffered.

[0078] Further, a guiding groove 442a is provided on the end face of the second moving plate 442 facing the tray 10, and a second buffer member 1243b is provided on the second pull rod 1243a. The guiding groove 442a corresponds to the second buffer member 1243b, and in the first state, the guiding groove 442a and the second buffer member 1243b are in abutting cooperation with each other.

[0079] As Figure 5 shown, there are two second moving plates 442, which are respectively located on both sides of the first push-pull mechanism 123. A guiding groove 442a is provided on the end face of each second moving plate 442. The second buffer member 1243b can be a spring damper or a hydraulic damper. The guiding groove 442a is correspondingly arranged with the second buffer member 1243b. On the one hand, it can buffer the impact force received by the second driving mechanism 42 and the second push-pull mechanism 124 during the process of driving the second clamping plate 122 to perform the opening and closing actions, avoiding damage to the components; on the other hand, it can also prevent the second driving mechanism 42 and the second push-pull mechanism 124 from being unable to cooperate to perform the opening and closing actions of the second clamping plate 122 due to the position deviation between the guiding groove 442a and the second buffer member 1243b.

[0080] Furthermore, the number of the second clamping plates 122 is multiple, and the multiple second clamping plates 122 are arranged in parallel and at intervals. A support seat 120 is arranged between adjacent second clamping plates 122. In the first state, an accommodation space for accommodating the battery module M is formed between two adjacent second clamping plates 122 and the support seat 120.

[0081] The number of the second push-pull mechanisms 124 is multiple, and the multiple second push-pull mechanisms 124 are connected to the multiple second clamping plates 122 in a one-to-one correspondence.

[0082] As Figure 3 shown, the number of the first clamping plates 121 is 1, and the number of the second clamping plates 122 is 5. In the first state, an accommodation space for accommodating the battery module M is formed between the first clamping plate 121 and the adjacent second clamping plate 122 and the support seat 120. An accommodation space for accommodating the battery module M can also be formed between the other two adjacent second clamping plates 122 and the support seat 120. A total of 5 battery modules M can be accommodated. Correspondingly, the number of the second push-pull mechanisms 124 can also be 5. The lengths of the second pull rod assemblies 1243 of the 5 second push-pull mechanisms 124 show an increasing trend, so as to facilitate the cooperation between the second pull rod assemblies 1243 of each second push-pull mechanism 124 and the corresponding second clamping plate 122. Of course, the tray 10 can also accommodate more battery modules M, such as 3 or 8. Correspondingly, the number of the second push-pull mechanisms 124 is also 3 or 8.

[0083] Figure 9 Shows Figure 2 the structural schematic diagram of the jacking mechanism in

[0084] As Figure 2 and Figure 9As shown in the figure, the jacking mechanism 3 includes a wedge assembly 31 and a lifting assembly 32. The wedge assembly 31 includes a fixed frame 311, a fifth power source 312, a third guiding assembly 314, a connecting rod 315, and a wedge block 316 with a slope surface. The fifth power source 312 is fixedly connected to the fixed frame 311. The third guiding assembly 314 extends in the horizontal direction and is arranged between the fixed frame 311 and the connecting rod 315. The connecting rod 315 is arranged between the output end of the fifth power source 312 and the output end of the sixth power source 313. The wedge block 316 is connected to the connecting rod 315. Among them, when the fifth power source 312 drives the connecting rod 315 to drive the wedge block 316 to move horizontally, the wedge block 316 provides a vertical jacking force or a descending force for the lifting assembly 32 through the slope surface. Optionally, wedge blocks 316 are respectively arranged at both ends of the connecting rod 315.

[0085] The third guiding assembly 314 is arranged between the fixed frame 311 and the connecting rod 315. The wedge block 316 is arranged on the connecting rod 315. The third guiding assembly 314 is used to provide a guiding effect for the horizontal movement of the wedge block 316. In addition, wedge blocks 316 are respectively arranged at both ends of the connecting rod 315. The output end of the fifth power source 312 can drive the connecting rod 315 to drive the two wedge blocks 316 to move horizontally, ensuring that during the process of the wedge block 316 on the connecting rod 315 moving horizontally along with the connecting rod 315, the variation amount of its slope surface in the vertical direction is within the allowable range, thereby improving the movement accuracy of the lifting assembly 32 in the vertical direction. The fifth power source 312 can be a cylinder, a hydraulic cylinder, a linear motor, etc.

[0086] Further, the lifting assembly 32 includes a jacking frame 321, a jacking platform 322, a positioning assembly 323, and a fourth guiding assembly 324. The positioning assembly 323 is arranged at a predetermined height of the fixed frame 311 and is used to position the tray 10. The fourth guiding assembly 324 extends in the vertical direction and is arranged between the jacking frame 321 and the fixed frame 311. A roller 325 in contact with the slope surface of the wedge block 316 is arranged at one end of the jacking frame 321 away from the jacking platform 322.

[0087] The fourth guiding component 324 extends in the vertical direction and is arranged between the lifting platform 322 and the lifting frame 321, and is used to provide guiding for the vertical movement of the lifting platform 322. The roller 325 of the lifting frame 321 contacts the inclined plane of the wedge block 316, and the roller 325 can reduce the frictional resistance between it and the inclined plane of the wedge block 316. When the wedge block 316 moves horizontally, the roller 325 will drive the lifting platform 322 to rise vertically along the inclined plane of the wedge block 316. For example, the lifting platform 322 rises to be flush with the predetermined height of the fixed frame 311, and then drives the tray 10 and the battery module M to be lifted, automatically completing the loading. After the battery modules M are stacked, the roller 325 will drive the lifting platform 322 to descend vertically along the inclined plane of the wedge block 316, driving the tray 10 and the battery module M to descend.

[0088] As Figure 9 shown, the stacking system of the battery module further includes a position sensor 8, and the position sensor 8 is arranged on one side of the lifting mechanism 3 facing the movable channel, and is used to detect whether the transport vehicle 1 reaches the preset position of the movable channel. The position sensor 8 can be a photoelectric inductor or an infrared inductor, and sends an electrical signal when the transport vehicle 1 reaches the preset position of the movable channel.

[0089] As Figure 2 and Figure 4 shown, the stacking system of the battery module further includes a leveling driving device 6 arranged on the clamping platform 20, and a leveling positioning component 13 corresponding to the leveling driving device 6 is correspondingly arranged on the bottom plate 11 of the tray 10, and is used to sort out the battery modules M stacked in the clamping mechanism 12 to prevent the batteries from being squeezed and deformed due to position deviation.

[0090] As Figure 2 and Figure 4 shown, the stacking system of the battery module further includes a support beam 21, a sixth power source 22 and a fifth guiding component 23 at one end of the movable channel. The sixth power source 22 is fixedly connected to the support beam 21, the fifth guiding component 23 is movably connected to the support beam 21, the clamping platform 20 is fixedly connected to the slider of the fifth guiding component 23, and the output end of the sixth power source 22 is connected to the clamping platform 20 to drive the clamping platform 20 to lift.

[0091] The sixth power source 22 can be a cylinder, a hydraulic cylinder, a linear motor, etc. The output end of the sixth power source 22 drives the clamping platform 20 to lift, and the fifth guiding component 23 is used to guide the lifting movement of the clamping platform 20. When the battery modules M are stacked on the tray 10, the clamping platform 20 rises, allowing the transport vehicle 1 to carry the battery modules M to leave from one end of the movable channel and enter the next working station. The transport vehicle 1 does not need to turn and can directly leave from the operating station. Then the clamping platform 20 descends to its original position, waiting for the next transport vehicle 1 to enter the operating station 2 to perform the stacking operation of the next group of battery modules M.

[0092] Figure 10 Show Figure 1 Schematic structural diagram of the code scanning component in the battery module stacking system shown.

[0093] As Figure 10 As shown, the battery module stacking system further includes a code scanning component 7. The code scanning component 7 includes a code scanning frame 71, a sliding table 72 and a scanning device 73. The code scanning frame 71 is arranged adjacent to the support beam 21. The sliding table 72 is slidably arranged on the top of the code scanning frame 71. The scanning device 73 is arranged on the sliding table 72 and is arranged opposite to the operating robot.

[0094] The sliding table 72 can be driven by a pulley and can slide back and forth along the top of the code scanning frame 71, which is convenient for adjusting the position of the scanning device 73 according to the position of the transport vehicle 1 in the movable channel, so that the scanning device 73 can scan the bar code or two-dimensional code of the tray 10, etc. The number of the scanning devices 73 can be the same as the number of columns of the battery modules M. For example, there are 5 scanning devices 73 in total. Each scanning device 73 is used to scan a column of batteries. A bar code or two-dimensional code is arranged on one side of a column of batteries. This column of batteries corresponds to a single jaw component of the jaws of the operating robot. The single jaw component is also provided with a bar code or two-dimensional code, which is convenient for traceability tracking and data management.
