[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features. In some utility model descriptions, "plurality" means two or more, unless otherwise specifically specified.
[0033] The utility model provides a battery core restraint and release mechanism, which is used for restraining and releasing a clamping structure on a tray, so that the clamping structure can clamp or release the battery core.
[0034] Combine Figure 1 and Figure 3 A battery cell restraint and release mechanism includes a base 100, a displacement structure 200, and a restraint structure 300. The displacement structure 200 is disposed on the base 100 and is used to receive and move a tray 700. The restraint structure 300 can be disposed on the base 100 and detachably connects to the tray 700 on the displacement structure 200 to adjust and release the clamping structure on the tray 700.
[0035] Furthermore, the restraint structure 300 includes a restraint driving member 310, which is arranged on one side of the displacement structure 200. The driving end of the restraint driving member 310 is provided with a disassembly and assembly member 320. The disassembly and assembly member 320 is used to be detachably connected to the clamping structure on the tray 700. The restraint driving member 310 can drive the disassembly and assembly member 320 to drive the clamping structure of the tray 700 to move, so that the clamping structure can clamp or release the battery cell.
[0036] Specifically, for example, the tray 700 can be moved in the second direction to one side of the restraint structure 300 via the displacement structure 200. The disassembly member 320 is then connected to the clamping structure on the tray 700. The restraint driver 310 drives the disassembly member 320 to move the clamping structure of the tray 700 in the first direction, thereby loosening the clamping structure of the tray 700, allowing the clamping structure to clamp or release the battery cells. It is understood that when the clamping structure is loosened, battery cells can be easily loaded into or removed from the tray 700. When the clamping structure is clamped, the battery cells on the tray 700 can be clamped and fixed.
[0037] For example, an empty pallet 700 can be loaded onto the displacement structure 200, and with the cooperation of the displacement structure 200, the pallet 700 is moved to one side of the restraint structure 300, and then the disassembly and assembly part 320 is connected to the clamping structure on the pallet 700, and the restraint driving part 310 drives the disassembly and assembly part 320 to drive the clamping structure of the pallet 700 to move along the first direction, so that the clamping structure is loosened, and then the battery cell can be loaded into the pallet 700. After the battery cell is loaded into the pallet 700, the restraint driving part 310 can drive the disassembly and assembly part 320 to enable the clamping structure to clamp the battery cell. After the clamping structure clamps the battery cell, the disassembly and assembly part 320 is removed from the clamping structure. At this time, the pallet 700 with the battery cell clamped can be transferred from the displacement structure 200 to other processes for processing, such as chemical separation and capacity division. In the above embodiment, the first direction is perpendicular to the second direction.
[0038] When the battery cells on the tray 700 are processed, the tray 700 can be transferred back to the displacement structure 200 again, and the above steps are repeated to remove the processed battery cells from the tray 700 and place new battery cells.
[0039] That is to say, in the battery cell restraint and release mechanism of the present application, a displacement structure 200 and a restraint structure 300 are provided. The displacement structure 200 can be used to conveniently transfer the tray 700 to the restraint structure 300. The restraint structure 300 is detachably connected to the clamping structure of the tray 700 through the disassembly and assembly part 320. When the disassembly and assembly part 320 is connected to the clamping structure, the restraint driving part 310 in the restraint structure 300 can drive the clamping structure to move by driving the disassembly and assembly part 320, so that the clamping structure of the tray 700 can be loosened, thereby facilitating the loading or replacement of the battery cells in the tray 700. When the battery cells are loaded in the tray 700, the disassembly and assembly part 320 is driven to enable the clamping structure to clamp the battery cells. After the clamping structure clamps the battery cells, the disassembly and assembly part 320 is removed from the clamping structure, and the tray 700 with the battery cells clamped is transferred to the next process. It can be seen that the battery cell restraint and release mechanism of the present application can quickly replace the battery cells on the tray 700.
[0040] See Figure 4In order to facilitate understanding of how the battery cell restraint and release mechanism realizes the clamping structure on the restraint and release tray 700, a tray 700 that can cooperate with the battery cell restraint and release mechanism of the present application can be provided.
[0041] The tray 700 may include a base plate 710, a first end plate 720, a second end plate 730, and a pressure plate 740. The first end plate 720 and the second end plate 730 are located on either side of the base plate 710, respectively. The pressure plate 740 is disposed between the first end plate 720 and the second end plate 730 and is capable of moving back and forth between the first end plate 720 and the second end plate 730. The pressure plate 740 is configured to be detachably connected to the assembly and disassembly component 320 in the battery cell attachment and release mechanism.
[0042] Furthermore, in some embodiments, a locking member 750 may be provided between the pressure plate 740 and the first end plate 720. Specifically, the restraint driver 310 can drive the disassembly member 320 to move the pressure plate 740 away from the second end plate 730, at which time a battery cell can be placed between the pressure plate 740 and the second end plate 730. After the battery cell is placed between the pressure plate 740 and the second end plate 730, the restraint driver 310 can drive the disassembly member 320 to move the pressure plate 740 toward the second end plate 730 to clamp the battery cell. After the pressure plate 740 and the second end plate 730 cooperate to clamp the battery cell, the pressure plate 740 and the first end plate 720 are fixed by the locking member 750, so that the pressure plate 740 remains in a state of clamping the battery cell.
[0043] In other embodiments, an elastic member may be provided between the pressure plate 740 and the first end plate 720, and the elastic member enables the pressure plate 740 to move toward the second end plate 730. At this time, a clamping structure of the tray 700 may be formed between the first end plate 720, the second end plate 730, the pressure plate 740 and the elastic member. The pressure plate 740 is connected to the disassembly and assembly part 320, and the restraint driving part 310 drives the pressure plate 740 to move along the first direction by driving the disassembly and assembly part 320, so that the pressure plate 740 moves away from the second end plate 730. At this time, a battery cell can be placed between the pressure plate 740 and the second end plate 730. After the restraint driving part 310 withdraws the driving force on the pressure plate 740 by driving the disassembly and assembly part 320, the pressure plate 740 can cooperate with the second end plate 730 under the action of the elastic member to compress the battery cell.
[0044] Combine Figure 2 and Figure 4 The disassembly and assembly part 320 may include a first connecting part 321 and a second connecting part 322. One end of the first connecting part 321 is connected to the restraint driving part 310. The other end of the first connecting part 321 is provided with a first clamping part 323. The clamping structure is provided with a second clamping part 760. The second connecting part 322 is clamped and connected with the first clamping part 323 and the second clamping part 760 respectively.
[0045] Specifically, the tray 700 moves to one side of the restraint structure 300 under the action of the displacement structure 200, so that the second connection part 322 can be clamped and connected with the first clamping part 323 on the first connection part 321 and the second clamping part 760 on the clamping structure respectively, that is, the second connection part 322 connects the first connection part 321 of the restraint structure 300 and the clamping structure together to realize the detachable connection between the disassembly part 320 and the clamping structure.
[0046] For example, the second clamping portion 760 of the clamping structure may be disposed on the pressing plate 740 of the clamping structure.
[0047] Furthermore, in some embodiments, the first clamping portion 323 can be a first annular groove provided on the outer wall of the first connecting portion 321, the second clamping portion 760 can be a second annular groove provided on the clamping structure, and the second connecting portion 322 is clamped with the first annular groove and the second annular groove respectively.
[0048] In some embodiments, in order to facilitate the clamping of the second connecting portion 322 with the first annular groove and the second annular groove respectively, and at the same time ensure the stability of the clamping, the second connecting portion 322 may include a connecting body 3221, and the connecting body 3221 is provided with a accommodating groove 3222, and a clamping block 3223 is provided on both sides of the accommodating groove 3222. The clamping blocks 3223 clamp the first annular groove and the second annular groove respectively, and the part of the first connecting portion 321 on one side of the first annular groove and the part of the clamping structure on one side of the second annular groove are accommodated in the accommodating groove 3222.
[0049] Furthermore, in order to prevent the second connecting part 322 from detaching from the first clamping part 323 and the second clamping part 760 when the restraint driving part 310 drives the clamping structure to move, a first pin hole 325 may also be provided on the second connecting part 322, and a second pin hole 770 is respectively provided on the first clamping part 323 and / or the second clamping part 760, and the first pin hole 325 and the second pin hole 770 are connected by a pin 324.
[0050] Specifically, after the second connecting part 322 and the first holding part 323 and the second holding part 760 are held together, the first connecting part 321 and the first holding part 323 and / or the second holding part 760 are fixed by inserting the pin 324 into the first pin hole 325 and the second pin hole 770 to prevent the second connecting part 322 from being separated from the first holding part 323 and the second holding part 760 due to vibration or other reasons.
[0051] Combine Figure 1 and Figure 3 The battery cell restraint and release mechanism may further include a stopper 400 , wherein the stopper 400 and the restraint driving member are respectively arranged on both sides of the displacement structure along the first direction, for stopping the tray 700 in the first direction.
[0052] Specifically, on the one hand, when the tray 700 moves on the displacement structure 200 to the side of the restraint structure 300, the stopper 400 can guide the displacement of the tray 700 to prevent the tray 700 from separating from the displacement structure 200 during the movement. On the other hand, when the restraint structure 300 drives the clamping structure of the tray 700 to move along the first direction, the stopper 400 can stop the tray 700 to prevent the tray 700 from moving as a whole along the first direction with the clamping structure.
[0053] Combine Figure 1 and Figure 3 The cell restraint release mechanism may further include a material stopper 500, which is detachably disposed at both ends of the displacement structure 200 in the second direction. In some embodiments, the material stopper 500 may be a latch.
[0054] Specifically, when the tray 700 moves to one side of the restraint structure 300 under the action of the displacement structure 200, the material stopper 500 can be installed on the two end sides of the displacement structure 200 to prevent the tray 700 from moving on the displacement structure 200 and detaching from the displacement structure 200 when the restraint structure 300 drives the clamping structure of the tray 700 to move.
[0055] See Figure 1 The displacement structure 200 may include a plurality of transmission rollers 210 , and the plurality of transmission rollers 210 are respectively disposed on the base 100 along the second direction.
[0056] For example, in some embodiments, the displacement structure 200 can be docked with a factory assembly line or an AGV, so that the pallet 700 on the assembly line or the AGV can flow to the transmission roller 210 of the displacement structure 200 .
[0057] In some embodiments, the tray 700 may be moved on the transmission roller 210 by being pushed by an external force, or the transmission roller 210 itself may drive the tray 700 to move.
[0058] See Figure 1 The battery cell restraint release mechanism may further include a lifting structure 600 , which is disposed on the base 100 and can lift the battery cells on the tray 700 between two adjacent transmission rollers 210 to facilitate removal of the battery cells from the tray 700 .
[0059] For example, in some embodiments, a clearance hole is provided on the bottom plate 710 of the tray 700 at the position corresponding to the battery cell. After the lifting structure 600 rises from between the two transmission rollers 210, the battery cell is lifted to a certain height through the clearance hole to facilitate the removal of the battery cell from the tray 700.
[0060] See Figure 3The present application also provides a loading and unloading device, including a tray 700 and a battery cell restraint release mechanism. The tray 700 is carried on the displacement structure 200 and can be detachably connected to the disassembly component 320.
[0061] When loading the battery cells, the empty tray 700 can be loaded onto the displacement structure 200 (it can be loaded onto the displacement structure 200 by manual handling, assembly line docking with the displacement structure 200, AGV trolley handling, etc.), and with the cooperation of the displacement structure 200, the tray 700 is moved to one side of the restraint structure 300, and then the disassembly and assembly part 320 is connected to the clamping structure on the tray 700, and the restraint driving part 310 drives the disassembly and assembly part 320 to drive the clamping structure of the tray 700 to move along the first direction, so that the clamping structure is loosened, and then the battery cells can be loaded into the tray 700. After the battery cells are loaded into the tray 700, the restraint driving part 310 can drive the disassembly and assembly part 320 to enable the clamping structure to clamp the battery cells. After the clamping structure clamps the battery cells, the disassembly and assembly part 320 is removed from the clamping structure. At this time, the tray 700 with the battery cells clamped can be transferred from the displacement structure 200 to other processes for processing, such as chemical separation and capacity separation.
[0062] When the battery cells on the tray 700 are processed, the tray 700 can be transferred back to the displacement structure 200 again, and the above steps are repeated to remove the processed battery cells from the tray 700 and place new battery cells.
[0063] The loading and unloading device of the present application can realize loading and unloading of battery cells.
[0064] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of some utility models should be included in the scope of protection of some utility models.
