Description

Technical Field

[0001] This application relates to the field of solid-state battery isostatic pressing equipment technology, and in particular to a continuous isostatic pressing production system for all-solid-state batteries. Background Technology

[0002] Traditional lithium-ion batteries rely on liquid electrolytes and separators, while all-solid-state batteries achieve ion conduction through solid electrolytes. They are a battery technology that uses only solid electrodes and solid electrolytes, containing no liquid or gel components. The fabrication of all-solid-state batteries often involves isostatic pressing, a process that uses uniform high-pressure densification to address challenges such as interfacial contact and energy density, thereby improving overall performance. Currently, to improve the efficiency of isostatic pressing, automated production lines can be used. However, existing isostatic pressing processes typically only involve the automatic loading and unloading of the batteries within the isostatic pressing unit; the level of automation still needs further improvement. Utility Model Content

The jaw lifting assembly drives the pair of battery cell clamping jaws to rise or fall. The jaw telescopic assembly drives the pair of battery cell clamping jaws to extend between the first pressure plate and the second pressure plate, or drives the pair of battery cell clamping jaws to retract from between the first pressure plate and the second pressure plate.

[0013] In one embodiment, the first pressure plate and the second pressure plate are connected by a screw connector, and the battery cell loading and unloading device further includes a screw connector tightening mechanism for tightening or loosening the screw connector.

[0014] In one embodiment, the all-solid-state battery continuous isostatic pressing production system further includes a liquid blowing and drying device, which is disposed on the fixture transfer device and upstream of a set of cell loading and unloading devices for unloading.

[0033] This application provides a continuous isostatic pressing production system for all-solid-state batteries, such as... Figures 1 to 6 As shown, the continuous isostatic pressing production system for all-solid-state batteries includes:

[0034] Fixture transfer device 01;

[0035] The cell clamping fixture 02 is set on the fixture transfer device 01 and is used to clamp the cells of the all-solid-state battery. The fixture transfer device 01 transfers the cell clamping fixture 02.

[0036] The battery cell loading and unloading device 03 is set on the fixture transfer device 01, and at least two sets are provided. One set of battery cell loading and unloading device 03 is used to assemble the battery cell into the battery cell clamping fixture 02, and the other set of battery cell loading and unloading device 03 is used to remove the battery cell from the battery cell clamping fixture 02.

[0037] Isostatic pressure device 04, which is used to perform isostatic pressure on the battery cell;

[0038] The fixture loading and unloading device 05 is used to load the battery cell clamping fixture 02 into the isostatic pressing device 04, and to unload the battery cell clamping fixture 02 from the isostatic pressing device 04.

[0039] like Figure 1 As shown in this embodiment, the cell clamping fixture 02 can be used as a tooling fixture for arranging all-solid-state battery cells. One or more cells can be arranged within the cell clamping fixture 02, meaning the isostatic pressing production system can perform isostatic pressing on each cell individually or on several cells simultaneously. The fixture transfer device 01 can be configured as a production line, and one or more cell clamping fixtures 02 can be mounted on the fixture transfer device 01. The cell clamping fixture 02 can be reasonably controlled in terms of its start / stop actions and transfer speed according to actual needs, so that the various devices within the system can perform corresponding operations.

[0040] In this embodiment, an isostatic pressing device 04 may be provided in the middle of the fixture transfer device 01. When a battery cell is assembled in the battery cell clamping fixture 02, the battery cell can be fed into the isostatic pressing device 04, which can then perform isostatic pressing treatment on the battery cell. The battery cell clamping fixture 02 has a cutout at least at the position where the battery cell needs to undergo isostatic pressing treatment, so as to facilitate contact between the battery cell and the isostatic pressing medium.

[0041] like Figure 1 As shown, the battery cell clamping fixture 02, equipped with battery cells, can be loaded into the isostatic pressing device 04 via the fixture loading / unloading device 05. Simultaneously, after the isostatic pressing device 04 performs isostatic pressing on the battery cells, they can also be unloaded from the isostatic pressing device 04 via the fixture loading / unloading device 05. The fixture loading / unloading device 05 can be a horizontally movable robotic arm 052, for example, mounted on a crane 051. The robotic arm 052 can be connected to the battery cell clamping fixture 02 via components such as automatic locking mechanisms. The robotic arm 052 can be lifted or translated via linear modules or other drive devices, and can be flipped via motors or other drive devices. Its specific configuration can be rationally selected and combined according to actual needs. Several isostatic pressing devices 04 can be spaced apart, and the horizontally movable robotic arm 052 can sequentially feed materials to several isostatic pressing devices 04 to improve the efficiency of battery cell isostatic pressing.

[0042] Of course, in some embodiments, the jig loading and unloading device 05 can be configured as two sets, for loading the battery cell clamping jig 02 into the isostatic pressing device 04 and for unloading the battery cell clamping jig 02 from the isostatic pressing device 04, respectively.

[0043] like Figure 1As shown, in this embodiment, the jig transfer device 01 may be equipped with two sets of battery cell loading and unloading devices 03. The two sets of battery cell loading and unloading devices 03 may be respectively set up upstream and downstream of the jig transfer device 01. One set of battery cell loading and unloading devices 03 is used to assemble the battery cell into the battery cell clamping jig 02, while the other set of battery cell loading and unloading devices 03 is used to remove the battery cell from the battery cell clamping jig 02.

[0044] When the battery cell undergoes isostatic pressing, the fixture transfer device 01 transfers the battery cell clamping fixture 02 to the location of the battery cell loading / unloading device 03, which then assembles the battery cell into the battery cell clamping device. The fixture loading device then loads the battery cell clamping device with the assembled battery cell into the isostatic pressing device 04, which then performs isostatic pressing on the battery cell. Subsequently, the fixture loading / unloading device 05 unloads the battery cell clamping fixture 02, now containing the isostatically pressed battery cell, from the isostatic pressing device 04 and repositions it on the fixture transfer device 01. Finally, the battery cell loading / unloading device 03 removes the battery cell from the battery cell clamping device.

[0045] It is understood that this application, by setting two sets of cell loading and unloading devices 03 on the fixture transfer device 01, and by using one set of cell loading and unloading devices 03 to assemble the cells into the cell clamping fixture 02, and by using the other set of cell loading and unloading devices 03 to remove the cells from the cell clamping fixture 02, can realize the automatic loading and unloading of cells in the cell clamping equipment. This, combined with the automatic loading and unloading of the cell clamping fixture 02 with the cells assembled in the isostatic pressing device 04, can further improve the automation level of the cells of all-solid-state batteries in the isostatic pressing process, thereby reducing labor costs and improving the working efficiency of the cells during isostatic pressing.

[0046] Specifically, the battery cell clamping fixture 02 includes a first pressure plate 021 and a second pressure plate 022. The second pressure plate 022 is movably disposed relative to the first pressure plate 021. The battery cell loading and unloading device 03 includes a pressure plate lifting mechanism 031 and a battery cell clamping mechanism 032. The pressure plate lifting mechanism 031 is used to lift the second pressure plate 022 from the first pressure plate 021 or to lower the second pressure plate 022. The battery cell clamping mechanism 032 is used to clamp the battery cell to place the battery cell between the second pressure plate 022 and the first pressure plate 021, or to remove the battery cell from between the first pressure plate 021 and the second pressure plate 022.

[0047] like Figure 2As shown in this embodiment, the battery cell clamping fixture 02 may include a first pressure plate 021 and a second pressure plate 022 movably disposed relative to the first pressure plate 021. The first pressure plate 021 and the second pressure plate 022 can clamp and fix the battery cell to facilitate isostatic pressing. The battery cell loading / unloading device 03 is used to load the battery cell between the first pressure plate 021 and the second pressure plate 022, or to remove the battery cell from between the first pressure plate 021 and the second pressure plate 022. The battery cell loading / unloading device 03 may include a pressure plate lifting mechanism 031 for lifting the second pressure plate 022 from the first pressure plate 021, or lowering the second pressure plate 022, and a battery cell clamping structure for clamping the battery cell and placing the battery cell between the first pressure plate 021 and the second pressure plate 022, or removing the battery cell from between the first pressure plate 021 and the second pressure plate 022.

[0048] Of course, in some embodiments, the second pressure plate 022 can also be configured as several layers, and the battery cell can also be disposed between two adjacent layers of the second pressure plate 022. At the same time, the pressure plate lifting mechanism 031 can also be used to lift or lower the uppermost second pressure plate 022 among the adjacent second pressure plates 022; the battery cell clamping mechanism 032 can also place the battery cell between two adjacent layers of the second pressure plate 022, or remove the battery cell from between two adjacent layers of the second pressure plate 022.

[0049] like Figure 2 As shown, in this embodiment, when a battery cell needs to be assembled into the battery cell clamping fixture 02, the pressure plate lifting mechanism 031 lifts the second pressure plate 022 from the first pressure plate 021. Then, the battery cell clamping mechanism 032 clamps the battery cell to be loaded and further places the battery cell between the first pressure plate 021 and the second pressure plate 022. Then, the pressure plate lifting mechanism 031 lowers the second pressure plate 022 so that the second pressure plate 022 presses down on the battery cell. When a battery cell needs to be removed from the battery cell clamping fixture 02, the pressure plate lifting mechanism 031 lifts the second pressure plate 022 from the first pressure plate 021. Then, the battery cell clamping mechanism 032 clamps the battery cell located in the battery cell clamping fixture 02 and further removes the battery cell from between the first pressure plate 021 and the second pressure plate 022. Finally, the pressure plate lifting mechanism 031 places the second pressure plate 022 on the first pressure plate 021.

[0050] It is understood that this embodiment facilitates the automated loading and unloading of battery cells within the battery cell clamping device by setting the battery cell clamping fixture 02 on the first pressure plate 021 and the second pressure plate 022, and by setting the battery cell loading and unloading device 03 on the pressure plate lifting mechanism 031 for lifting or lowering the second pressure plate 022 and the battery cell clamping mechanism 032 for clamping the battery cell and for placing or removing the battery cell.

[0051] More specifically, the pressure plate lifting mechanism 031 includes pressure plate hooks 311, hook clamping assembly 312, and hook lifting assembly 313. A pair of pressure plate hooks 311 are provided, and the pair of pressure plate hooks 311 are arranged opposite to each other. The hook clamping assembly 312 drives the pair of pressure plate hooks 311 to move closer to each other to engage with the second pressure plate 022, or drives the pair of pressure plate hooks 311 to move away from each other to separate from the second pressure plate 022. The hook lifting assembly 313 drives the pair of pressure plate hooks 311 to rise to lift the second pressure plate 022, or drives the pair of pressure plate hooks 311 to fall to lower the second pressure plate 022.

[0052] like Figure 3 As shown in this embodiment, by way of example, a pair of pressure plate hooks 311 can be connected to a hook clamping assembly 312. The hook clamping assembly 312 can be an electric cylinder, preferably a bidirectional electric cylinder. In this case, the hook clamping assembly 312 can drive the pair of pressure plate hooks 311 to move synchronously in opposite directions. When the pair of pressure plate hooks 311 approach each other, they can overlap with the second pressure plate 022 from both ends. When the pair of pressure plate hooks 311 move away from each other, they can separate from the second pressure plate 022.

[0053] Of course, in some embodiments, the hook gripper assembly 312 can also be configured as a one-way cylinder. In this case, the hook gripper assembly 312 can be connected to one of a pair of pressure plate hooks 311, while the other of the pair of pressure plate hooks 311 can be fixedly configured. When the hook gripper assembly 312 drives the movable pressure plate hook 311 to move closer to the fixed pressure plate hook 311, it can engage with the second pressure plate 022; and when the hook gripper assembly 312 drives the movable pressure plate hook 311 to move closer to the fixed pressure plate hook 311, it can separate from the second pressure plate 022.

[0054] like Figure 2 and Figure 3 As shown, in this embodiment, the claw gripping assembly 312 can be disposed on the first lifting base 314, and the first lifting base 314 can be connected to the claw lifting assembly 313. The claw lifting assembly 313 can be a linear module, which can be vertically arranged and includes a vertically slidable module slider. The first lifting base 314 can be disposed on the module slider of the claw lifting assembly 313. When the module slider of the claw lifting assembly 313 rises and falls, it can drive the first lifting base 314, the claw gripping assembly 312 disposed on the first lifting base 314, and the pair of pressure plate claws 311 to rise and fall synchronously.

[0055] like Figure 2 and Figure 3As shown, in this embodiment, when it is necessary to lift the second pressure plate 022, the pair of pressure plate hooks 311 can be driven away from each other to the maximum distance by the hook gripping assembly 312. Then, the first lifting base 314 can be driven down by the hook lifting assembly 313 so that the pair of pressure plate hooks 311 can move to both ends of the second pressure plate 022. Then, the pair of pressure plate hooks 311 can be driven closer to each other by the hook gripping assembly 312 so that the pair of pressure plate hooks 311 can overlap with the second pressure plate 022. Then, the first lifting base 314 can be driven up by the hook lifting assembly 313 so that the pair of pressure plate hooks 311 can lift the second pressure plate 022.

[0056] When the second pressure plate 022 needs to be lowered, the first lifting base 314 can be driven down by the hook lifting assembly 313 so that a pair of pressure plate hooks 311 can lower the second pressure plate 022 to a specified height. Then, the pair of pressure plate hooks 311 can be driven away from each other by the hook clamping assembly 312 so that the pair of pressure plate hooks 311 can be separated from the second pressure plate 022. Then, the first lifting base 314 can be driven up by the hook lifting assembly 313 to reset the pair of pressure plate hooks 311.

[0057] like Figure 3 As shown, in this embodiment, the pressure plate hook 311 may include a connecting portion 3111 and an overlapping portion 3112, wherein the overlapping portion 3112 may be disposed at the bottom of the connecting portion 3111, and the connecting portion 3111 can connect the overlapping portion 3112 to the hook clamping assembly 312. At this time, the pressure plate hook 311 has a shape similar to a horizontally arranged "U" shape, with the overlapping portion 3112 being the bottom of the "U" shape, and the connecting portion 3111 being the top and side of the "U" shape. The openings of the "U" shape of a pair of pressure plate hooks 311 can be arranged opposite each other to facilitate the arrangement of both ends of the second pressure plate 022 within the openings of the "U" shape of the pair of pressure plate hooks 311. Meanwhile, the bottom length of the "U" shape of the pressure plate hook 311 is relatively short to avoid the hook clamping assembly 312 needing to drive a pair of pressure plate hooks 311 to move a long distance in order to arrange the pair of pressure plate hooks 311 at both ends of the second pressure plate 022; while the top length of the "U" shape of the pressure plate hook 311 is relatively long to facilitate the connection of the pair of pressure plate hooks 311 with the hook clamping assembly 312.

[0058] When a pair of pressure plate hooks 311 overlap with the second pressure plate 022, the overlapping portion 3112 of the pair of pressure plate hooks 311 can extend to the bottom of the second pressure plate 022 under the drive of the hook clamping assembly 312. Subsequently, when the pair of pressure plate hooks 311 rise under the drive of the hook lifting assembly 313, the pair of pressure plate hooks 311 can lift the second pressure plate 022 through their overlapping portion 3112. The "U"-shaped sides of the pair of pressure plate hooks 311 can be spaced apart from both ends of the second pressure plate 022, so that when the second pressure plate 022 is configured as several layers, one of the layers of the second pressure plate 022 can be lifted accurately without easily interfering with other layers of the second pressure plate 022.

[0059] When the pair of pressure plate hooks 311 separate from the second pressure plate 022, the overlapping part 3112 of the pair of pressure plate hooks 311 can retract from the bottom of the second pressure plate 022 under the drive of the hook clamping assembly 312. Then, when the pair of pressure plate hooks 311 rise under the drive of the hook lifting assembly 313, the purpose of lowering the second pressure plate 022 can be achieved.

[0060] It is understood that this embodiment sets the pressure plate lifting mechanism 031 as a pair of pressure plate hooks 311, a hook clamping assembly 312 for driving the pair of pressure plate hooks 311 to clamp or release the second pressure plate 022, and a hook lifting assembly 313 for driving the pair of pressure plate hooks 311 to lift and lower, so as to facilitate the automatic lifting and lowering of the second pressure plate 022, so as to facilitate the battery cell clamping mechanism 032 to pick up and put down the battery cell.

[0061] More specifically, the battery cell clamping mechanism 032 includes battery cell clamping claws 321, a claw clamping assembly 322, a claw lifting assembly 323, and a claw telescopic assembly 324. The battery cell clamping claws 321 are configured as a pair, and the pair of battery cell clamping claws 321 are arranged opposite to each other. The claw clamping assembly 322 drives the pair of battery cell clamping claws 321 to move closer to each other to clamp the battery cell, or drives the pair of battery cell clamping claws 321 to move further apart to release the battery cell. The claw lifting assembly 323 drives the pair of battery cell clamping claws 321 to rise or fall. The claw telescopic assembly 324 drives the pair of battery cell clamping claws 321 to extend between the first pressure plate 021 and the second pressure plate 022, or drives the pair of battery cell clamping claws 321 to retract from between the first pressure plate 021 and the second pressure plate 022.

[0062] like Figure 4 and Figure 5As shown in this embodiment, by way of example, a pair of battery cell clamping claws 321 can be connected to a claw clamping assembly 322, which can also be an electric cylinder, preferably a unidirectional electric cylinder. The claw clamping assembly 322 can be connected to one of the pair of battery cell clamping claws 321, while the other of the pair of battery cell clamping claws 321 can be fixed. When the claw clamping assembly 322 drives the movable battery cell clamping claw 321 to move closer to the fixed battery cell clamping claw 321, the pair of battery cell clamping claws 321 can clamp the battery cell from both sides; and when the claw clamping assembly 322 drives the movable battery cell clamping claw 321 to move away from the fixed battery cell clamping claw 321, the pair of battery cell clamping claws 321 can separate from the battery cell and release the battery cell.

[0063] Of course, in some embodiments, the gripper assembly 322 can also be preferably a bidirectional electric cylinder, in which case the gripper assembly 322 can drive a pair of battery cell gripping jaws 321 to move synchronously in opposite directions. When the pair of battery cell gripping jaws 321 approach each other, they can grip the battery cell. And when the pair of battery cell gripping jaws 321 move away from each other, they can release the battery cell.

[0064] like Figure 5 As shown, in this embodiment, the gripper holding assembly 322 can be disposed on the second lifting base 325, and the second lifting base 325 can be connected to the gripper lifting assembly 323. The gripper lifting assembly 323 can also be configured as a linear module, which can also be vertically arranged and includes a vertically slidable module slider. The second lifting base 325 can be disposed on the module slider of the gripper lifting assembly 323. When the module slider of the gripper lifting assembly 323 rises and falls, it can drive the second lifting base 325, the gripper holding assembly 322 disposed on the second lifting base 325, and the pair of cell gripping grippers 321 disposed on the second lifting base 325 to rise and fall synchronously.

[0065] like Figure 4As shown, the gripper lifting assembly 323 can be mounted on the translation base 326, which can be connected to the gripper telescopic assembly 324. The gripper telescopic assembly 324 can include a telescopic drive assembly 3241 and a telescopic guide assembly 3242. The telescopic drive assembly 3241 can be configured as a linear module, which can be horizontally positioned and includes a horizontally slidable module slider. The telescopic guide assembly 3242 can include a telescopic guide rail and a telescopic slider. The telescopic guide rail is parallel to and spaced apart from the telescopic drive assembly 3241, and the telescopic slider is slidably mounted on the telescopic guide rail. The translation base 326 can span across the telescopic slider and the module slider of the telescopic drive assembly 3241. When the module slider of the telescopic drive assembly 3241 translates, it can drive the translation base 326, the hook lifting assembly 313, the gripper holding assembly 322, and the pair of battery cell gripping grippers 321 mounted on the translation base 326 to translate synchronously. When the translation base 326 moves, it can also drive the telescopic slider to move synchronously on the telescopic guide rail. The telescopic slider and the telescopic guide rail cooperate to guide the movement of the translation base 326.

[0066] like Figure 2 As shown, in this embodiment, when it is necessary to place the battery cell between the first pressure plate 021 and the second pressure plate 022, the second pressure plate 022 can be lifted first by the pressure plate lifting mechanism 031, and then the second lifting base 325 can be lifted by the gripper lifting assembly 323 to move a pair of battery cell clamping grippers 321 to the same height position as the battery cell to be loaded. Then, the translation base 326 can be moved closer to the battery cell by the gripper telescopic assembly 324, and then the pair of battery cell clamping grippers 321 can be moved closer to each other by the gripper clamping assembly 322, so that the pair of battery cell clamping grippers 321 can clamp the battery cell to be loaded. Next, the second lifting base 325 can be raised or lowered by the gripper lifting assembly 323 to move the pair of cell-holding grippers 321 to a height position between the first pressure plate 021 and the second pressure plate 022. Then, the translation base 326 can be moved by the gripper telescopic assembly 324 so that the pair of cell-holding grippers 321 extend between the first pressure plate 021 and the second pressure plate 022. Then, the second lifting base 325 can be lowered by the gripper lifting assembly 323 to place the cell on the first pressure plate 021. Then, the pair of cell-holding grippers 321 can be moved away from each other by the gripper holding assembly 322 to release the cell. After that, the pair of cell-holding grippers 321 are reset under the drive of the gripper lifting assembly 323 and the gripper telescopic assembly 324, and the pressure plate lifting mechanism 031 can lower the second pressure plate 022.

[0067] When it is necessary to remove the battery cell from between the first pressure plate 021 and the second pressure plate 022, the second pressure plate 022 can be lifted first by the pressure plate lifting mechanism 031. Then, the pair of battery cell clamping jaws 321 are driven to move away from each other to the maximum distance by the jaw clamping assembly 322. Then, the second lifting base 325 is driven to rise and fall by the jaw lifting assembly 323 so that the pair of battery cell clamping jaws 321 move to the same height position as the battery cell. Then, the translation base 326 is driven to move closer to the battery cell by the jaw extension assembly 324 so that the pair of battery cell clamping jaws 321 extend between the first pressure plate 021 and the second pressure plate 022 and extend to both sides of the battery cell. Then, the pair of battery cell clamping jaws 321 are driven to move closer to each other by the jaw clamping assembly 322 so that the pair of battery cell clamping jaws 321 clamp the battery cell. Then, the jaw telescopic assembly 324 drives the translation base 326 to move, so that a pair of cell-holding jaws 321 retract from between the first pressure plate 021 and the second pressure plate 022. At this time, the pressure plate lifting mechanism 031 can lower the second pressure plate 022. Next, the jaw lifting assembly 323 drives the second lifting base 325 to rise and fall, so that a pair of cell-holding jaws 321 move to the height position where the cell is to be unloaded. Then, the jaw telescopic assembly 324 drives the translation base 326 to move, so that a pair of cell-holding jaws 321 move closer to the area to be unloaded. Then, the jaw lifting assembly 323 drives the second lifting base 325 to fall, so that the cell is placed in the area to be unloaded. Finally, the jaw holding assembly 322 drives the pair of cell-holding jaws 321 to move away from each other, so that the cell is released.

[0068] like Figure 5 As shown, in this embodiment, the battery cell clamping claw 321 may include a side portion 3211 and a bottom portion 3212, wherein the bottom portion 3212 may be disposed at the bottom of the side portion 3211 and may be perpendicular to the side portion 3211. In this case, the battery cell clamping claw 321 has an L-shaped form, and the bottom of the L-shape of the pair of battery cell clamping claws 321 may extend in a direction that approaches each other. When the pair of battery cell clamping claws 321 clamps the battery cell, the side portions 3211 of the pair of battery cell clamping claws 321 may respectively abut against the two sides of the battery cell, and the bottom portions 3212 of the pair of battery cell clamping claws 321 may both abut against the bottom of the battery cell. This allows the pair of battery cell clamping claws 321 to hold the battery cell firmly, so that the battery cell is not prone to falling off due to vibration.

[0069] like Figure 5As shown, in this embodiment, the cell clamping mechanism 032 may further include a cell pressure plate 327 and a pressure plate lifting assembly 328. The cell pressure plate 327 may be rectangular and can be movably disposed above a pair of cell clamping jaws 321, and can be horizontally disposed between the pair of cell clamping jaws 321. The cell pressure plate 327 may be connected to the pressure plate lifting assembly 328, which may be an electric cylinder that can drive the cell pressure plate 327 to slide vertically.

[0070] When a pair of cell-holding jaws 321 clamp the cell, the pressure plate lifting assembly 328 can drive the cell pressure plate 327 to descend, so that the cell pressure plate 327 abuts against the cell on the pair of cell-holding jaws 321, thereby pressing and fixing the cell. This can further improve the stability of the cell during the clamping process, and even if the cell is subjected to vibration, it is not easy for the cell to fall off. When it is necessary to release the cell, the pressure plate lifting assembly 328 can drive the cell pressure plate 327 to rise, so that the cell pressure plate 327 moves away from the cell, thereby releasing the cell, so that the pair of cell-holding jaws 321 can further release the cell.

[0071] It is understood that this embodiment can achieve automatic picking and placing of battery cells between the first pressure plate 021 and the second pressure plate 022 by configuring the battery cell clamping mechanism 032 as a pair of battery cell clamping jaws 321, a jaw clamping assembly 322 for driving the pair of battery cell clamping jaws 321 to clamp or release the battery cells, a jaw lifting assembly 323 for driving the pair of battery cell clamping jaws 321 to rise and fall, and a jaw telescopic assembly 324 for driving the pair of battery cell clamping jaws 321 to extend between the first pressure plate 021 and the second pressure plate 022 or to retract from the first pressure plate 021 and the second pressure plate 022.

[0072] More specifically, the first pressure plate 021 and the second pressure plate 022 are connected by a screw connector 023. The battery cell loading and unloading device 03 also includes a screw connector tightening mechanism 033, which is used to tighten or loosen the screw connector 023.

[0073] like Figure 1 and Figure 6As shown in this embodiment, by way of example, the screw connector 023 may include a screw 231 and a nut 232. The screw 231 may be disposed on a first pressure plate 021, and a second pressure plate 022 may be sleeved on the screw 231. The nut 232 may be threadedly connected to the screw 231, and the nut 232 may be disposed on the side of the second pressure plate 022 away from the first pressure plate 021. The screw connector tightening mechanism 033 may include a sleeve, a sleeve drive, and a sleeve lifting assembly. The sleeve may be sleeved outside the end of the screw 231, and the shape of its inner cavity may be adapted to the shape of the nut 232 to form a rotation limit with the nut 232 when sleeved outside the screw 231. The sleeve may be connected to the sleeve drive, which may be a motor that can drive the sleeve to rotate. The sleeve lifting assembly may be a linear module that may be vertically arranged and includes a vertically slidable module slider. The sleeve drive may be disposed on the module slider.

[0074] like Figure 1 As shown, in this embodiment, when the first pressure plate 021 and the second pressure plate 022 need to be locked and fixed by the screw connector 023, the sleeve driving component can be driven to descend by the sleeve lifting assembly so that the sleeve is sleeved on the outside of the nut 232. Then, the sleeve driving component drives the sleeve to rotate so as to tighten the nut 232. After that, the sleeve can be reset under the drive of the sleeve lifting assembly.

[0075] When it is necessary to loosen the first pressure plate 021 and the second pressure plate 022, the sleeve drive component can be lowered by the sleeve lifting assembly so that the sleeve is fitted over the nut 232. Then, the sleeve drive component drives the sleeve to rotate so as to loosen the nut 232. After that, the sleeve can be reset under the drive of the sleeve lifting assembly.

[0076] like Figure 1 As shown, in this embodiment, the screw fastening mechanism 033 can be configured as two sets. One set is located downstream of the set of battery cell loading and unloading devices 03 used for loading, so that after the battery cell loading and unloading device 03 assembles the battery cell into the battery cell clamping device, the first pressure plate 021 and the second pressure plate 022 are locked and fixed. The other set is located upstream of the set of battery cell loading and unloading devices 03 used for unloading, so that the first pressure plate 021 and the second pressure plate 022 are loosened before the battery cell loading and unloading device 03 removes the battery cell from the battery cell clamping device.

[0077] Of course, in some embodiments, the screw fastening mechanism 033 may also be set as a single set, which may also be set on the crane 051 to move closer to the set of battery cell loading and unloading devices 03 for loading or unloading respectively.

[0078] It is understandable that in this embodiment, the first pressure plate 021 and the second pressure plate 022 are tightened and fixed by the screw connector 023, which makes it difficult for the battery cell to shake or even fall out of the battery cell clamping fixture 02, so as to ensure the smooth progress of the isostatic pressing process of the battery cell; and by setting the screw connector tightening mechanism 033, the screw connector 023 can be automatically tightened and loosened, so that the continuous isostatic pressing production system of all solid-state batteries has a relatively high degree of automation.

[0079] like Figure 6 As shown, in this embodiment, the cell clamping fixture 02 may further include a base plate 024 and compression springs 025. The base plate 024 may be configured with a shape similar to the first pressure plate 021 and the second pressure plate 022, for example, the base plate 024, the first pressure plate 021, and the second pressure plate 022 may all be rectangular. The base plate 024 may be located on the side of the first pressure plate 021 away from the several layers of second pressure plates 022. The screw 231 may be located on the base plate 024, that is, the first pressure plate 021 and the several layers of second pressure plates 022 may be movably configured relative to the base plate 024. The compression springs 025 may be located between the base plate 024 and the first pressure plate 021, and there may be several compression springs 025, which may be distributed in a rectangular array between the base plate 024 and the first pressure plate 021.

[0080] When the screw connector 023 locks and fixes the first pressure plate 021 and the second pressure plate 022, it can press down the compression spring 025 through the first pressure plate 021 and the second pressure plate 022. The compression spring 025 can buffer the first pressure plate 021 and the second pressure plate 022 so that the battery cell is subjected to uniform force between the first pressure plate 021 and the second pressure plate 022.

[0081] like Figure 6As shown, in this embodiment, the cell clamping fixture 02 may further include a shim column 026. The shim column 026 may be a cylinder, which may be disposed between the first pressure plate 021 and the second pressure plate 022, and may be connected to either the first pressure plate 021 or the second pressure plate 022. That is, the shim column 026 may be arranged on the top of the first pressure plate 021 or on the bottom of the second pressure plate 022. Several shim columns 026 may also be provided, and these shim columns 026 may be distributed in a rectangular array. When the second pressure plate 022 is placed on the first pressure plate 021, the support column 026 can support the second pressure plate 022 to maintain an appropriate distance between the first pressure plate 021 and the second pressure plate 022, thereby preventing the battery cell from being damaged due to excessive pressure. Also, when a pair of pressure plate hooks 311 lift the second pressure plate 022, the pair of pressure plate hooks 311 can extend their overlapping portions 3112 to the bottom of the second pressure plate 022 to overlap with it. At this time, the height of the support column 026 is preferably not less than the height of the overlapping portion 3112. When the second pressure plate 022 is configured as several layers, the support column 026 can also be placed between adjacent layers of the second pressure plate 022.

[0082] like Figure 6 As shown, in this embodiment, both the first pressure plate 021 and the second pressure plate 022 can be provided with a soft pad layer 027 on the side near the battery cell. The soft pad layer 027 can be made of elastic materials such as rubber, plastic, or silicone. It is used to make flexible contact with the battery cell when the first pressure plate 021 and the second pressure plate 022 clamp the battery cell, so as to further prevent the first pressure plate 021 and the second pressure plate 022 from damaging the battery cell.

[0083] like Figure 6 As shown, in this embodiment, the cell clamping fixture 02 may further include guide rods 028. Several guide rods 028 may be provided; in this embodiment, four are preferred. The four guide rods 028 may be respectively disposed at the four corners of the base plate 024. The first pressure plate 021 and the second pressure plate 022 may also be sleeved on the four guide rods 028. Both the first pressure plate 021 and the second pressure plate 022 can be sleeved on the guide rods 028 via linear bearings 029. The linear bearings 029 correspond one-to-one with the guide rods 028, and the linear bearings 029 are slidably disposed on the guide rods 028. When the pressure plate lifting mechanism 031 lifts or lowers the second pressure plate 022, and when the screw connector 023 locks the first pressure plate 021 and the second pressure plate 022 onto the base plate 024, both the first pressure plate 021 and the second pressure plate 022 move vertically. This can drive the linear bearing 029 to move on the guide rod 028. The linear axis, in conjunction with the guide rod 028, can guide the movement of the first pressure plate 021 and the second pressure plate 022, making their movement more stable.

[0084] Specifically, the all-solid-state battery continuous isostatic pressing production system also includes a liquid blowing and drying device 06, which is installed on the fixture transfer device 01 and upstream of a set of cell loading and unloading devices 03 used for unloading. The liquid blowing and drying device 06 is used to blow liquid and dry the cell clamping fixture 02.

[0085] like Figure 1 As shown in this embodiment, it is exemplarily illustrated that before removing the battery cell from the battery cell clamping fixture 02, the battery cell clamping fixture 02 can be purged with liquid and dried, which can be accomplished by the purging and drying device 06. The purging and drying device 06 can be located upstream of a set of battery cell loading and unloading devices 03 used for unloading, and can also be located upstream of the aforementioned screw fastener tightening mechanism 033. The purging and drying device 06 can include a resistance wire and an air knife. The resistance wire can be located at the air inlet of the air knife to heat the airflow, and the heated airflow can be blown out from the air outlet of the air knife to achieve purging and drying of the battery cell clamping fixture 02.

[0086] It is understood that by setting up the liquid blowing and drying device 06, this embodiment can realize the automated liquid blowing and drying of the battery cell clamping fixture 02, so as to keep the battery cell clean after isostatic pressing, and at the same time ensure the cleanliness of the working environment.

[0087] Specifically, the fixture transfer device 01 includes a temporary storage platform 011, and the all-solid-state battery continuous isostatic pressing production system also includes an incoming material conveying device 07 and a cell transfer device 08, wherein the incoming material conveying device 07 is used to convey the cells, and the cell transfer device 08 is used to transfer the cells from the incoming material conveying device 07 to the temporary storage platform 011.

[0088] like Figure 1As shown in this embodiment, the jig transfer device 01 may include a temporary storage platform 011. A set of battery cell loading / unloading devices 03 for feeding can be arranged close to the temporary storage platform 011, and the battery cell loading / unloading devices 03 can assemble the battery cells on the temporary storage platform 011 into the battery cell clamping jig 02. The battery cells on the temporary storage platform 011 can be fed by an incoming material conveying device 07 and a battery cell transfer device 08. The incoming material conveying device 07 can be configured as a line, and the battery cells can be arranged at intervals on the incoming material conveying device 07 for conveying. The incoming material conveying device 07 can be configured in a straight line, and its discharge end can be arranged close to the temporary storage platform 011. The battery cell transfer device 08 can be arranged between the discharge end of the incoming material conveying device 07 and the temporary storage platform 011. It can be configured as a robot arm and is used to transfer the battery cells from the incoming material conveying device 07 to the temporary storage platform 011. The temporary storage platform 011 can be a multi-station interactive platform, for example, the temporary storage platform 011 specifically includes dual stations A and B that can rotate 180 degrees. During rotation, the battery cell transfer device 08 can first transfer the battery cell to station A of the temporary storage platform 011, and then the temporary storage platform 011 rotates, and the battery cell loading and unloading device 03 can remove the battery cell from station A; during this process, the battery cell transfer device 08 can continue to transfer the battery cell to station B of the temporary storage platform 011 to improve work efficiency.

[0089] It is understood that by setting up a temporary storage platform 011, and simultaneously setting up an incoming material conveying device 07 for conveying battery cells and a battery cell transfer device 08 for transferring battery cells from the incoming material conveying device 07 to the temporary storage platform 011, the automatic feeding of battery cells can be realized, thereby further improving the automation level of the system.

[0090] More specifically, the all-solid-state battery continuous isostatic pressing production system also includes a barcode rejection device 09, which is installed on the incoming material conveying device 07. The barcode rejection device 09 is used to scan the barcodes of the battery cells and to reject unqualified battery cells.

[0091] like Figure 1As shown in this embodiment, by way of example, the barcode rejection device 09 can be located upstream of the discharge end of the incoming material conveying device 07. Before the battery cells are conveyed by the incoming material conveying device 07 and before the battery cell transfer device 08 transfers the battery cells to the temporary storage platform 011, the barcode rejection device 09 can scan the battery cells. For example, the barcode rejection device 09 includes a laser scanning mechanism, which can obtain relevant information about the battery cells. Simultaneously, the barcode rejection device 09 can also reject unqualified battery cells. For example, in addition to the conveyor line 071 for conveying battery cells, the incoming material conveying device 07 can also include a rejection line 072, and the barcode rejection device 09 can include a guiding mechanism. When the barcode rejection device 09 identifies an unqualified battery cell, the guiding mechanism can send the unqualified battery cell from the conveyor line 071 into the rejection line 072, and the guiding mechanism can be a telescopically mounted push rod.

[0092] It is understood that by setting a barcode scanning and rejection device 09 on the incoming material conveying device 07, this embodiment can realize automatic barcode scanning of battery cells and automatic rejection of unqualified battery cells, so as to avoid wasting costs by performing isostatic pressing on unqualified battery cells.

[0093] More specifically, the all-solid-state battery continuous isostatic pressing production system also includes a feeding conveyor 10, a temporary storage platform 011 is located near the feeding conveyor 10, and a cell transfer device 08 is located between the feeding conveyor 10 and the temporary storage platform 011 near the feeding conveyor 10. The temporary storage platform 011 is also used to transfer the cells from the temporary storage platform 011 to the feeding conveyor 10.

[0094] like Figure 1 As shown in this embodiment, by way of example, the jig transfer device 01 may also have a temporary storage platform 011 located near the battery cell loading / unloading device 03 used for unloading; similarly, the temporary storage platform 011 may also be a multi-station interactive platform. The battery cell loading / unloading device 03 used for loading can unload the battery cells from the battery cell clamping jig 02 onto the temporary storage platform 011. The battery cells on the temporary storage platform 011 can be further unloaded via the unloading conveyor 10 and a set of battery cell transfer devices 08. The unloading conveyor 10 may be configured with a structure similar to the incoming material conveyor 07, and it is also used for conveying battery cells. The set of battery cell transfer devices 08 may be located between the unloading conveyor 10 and the temporary storage platform 011 near the unloading conveyor 10. The battery cell transfer device 08 can transfer the battery cells from the temporary storage platform 011 to the unloading conveyor 10.

[0095] It is understood that this embodiment can achieve automated unloading of battery cells by setting up a feeding conveyor 10 for conveying battery cells, setting up a temporary storage platform 011 near the feeding conveyor 10 on the fixture transfer device 01, and setting up a battery cell transfer device 08 for transferring battery cells between the temporary storage platform 011 and the feeding conveyor 10, so as to further improve the automation level of the system.

[0096] More specifically, the all-solid-state battery continuous isostatic pressing production system also includes a testing device 11, which is mounted on the feeding conveyor 10 and is used to test the battery cells.

[0097] like Figure 1 As shown in this embodiment, by way of example, after the battery cell undergoes isostatic pressing, further testing can be performed on the battery cell, which can be completed by the testing device 11. The testing device 11 can be installed on the feeding and conveying device 10, and it can include a battery cell short-circuit testing mechanism, which can perform short-circuit testing on the battery cell.

[0098] It is understood that by setting a testing device 11 on the feeding and conveying device 10, this embodiment can realize automatic testing of the battery cells after isostatic pressing, so as to ensure the quality of the battery cells after isostatic pressing.

[0099] More specifically, the all-solid-state battery continuous isostatic pressing production system also includes a cell drying device 12, which is installed on the feeding conveyor 10 and upstream of the testing device 11. The cell drying device 12 is used to dry the cells.

[0100] like Figure 1 As shown in this embodiment, it is exemplarily illustrated that before testing the isostatically charged battery cells, the cells can be dried first, which can be accomplished by the battery cell drying device 12. The battery cell drying device 12 can also be mounted on the feeding conveyor 10 and can be positioned upstream of the testing device 11. The battery cell drying device 12 may include a drying mechanism, which can achieve heating via a resistance wire. When the feeding conveyor 10 conveys the battery cells, the cells can pass through the drying structure to achieve drying.

[0101] It is understood that by setting a cell drying device upstream of the test device 11, this embodiment can dry the battery under isostatic pressure treatment, so as to avoid the medium remaining on the cell during isostatic pressure treatment and interfering with the cell test.

[0102] Specifically, the fixture transfer device 01 is configured as a rotary production line.

[0103] like Figure 1As shown in this embodiment, by way of example, the fixture transfer device 01 can be configured as a rotary production line, that is, the cell clamping fixture 02 can circulate on the fixture transfer device 01. The fixture transfer device 01 may include a working line 012, a return line 013, and a transition line 014, wherein the working line 012 and the return line 013 can be arranged in parallel, two temporary storage platforms 011 can be respectively arranged at both ends of the working line 012, and two sets of cell loading and unloading devices 03 and liquid blowing and drying devices 06 are all arranged on the working line 012; at the same time, the isostatic pressing device 04 can be arranged on one side of the working line 012, and the fixture loading and unloading device 05 can be arranged between the working line 012 and the return line 013. Two transition lines 014 can be configured, each connected between the two ends of the working line 012 and the return line 013, respectively, to facilitate the movement of the cell clamping fixture 02 between the working line 012 and the return line 013. The transition lines 014 can be arranged perpendicularly to the working line 012 and the return line 013, in which case the fixture transfer device 01 has a roughly rectangular shape. It is easy to see that the feeding direction of the return line 013 is opposite to that of the working line 012, and the feeding directions of the two transition lines 014 are opposite.

[0104] It is understood that this embodiment sets the jig transfer device 01 as a rotary production line to facilitate the automatic circulation of the cell clamping jig 02, thereby further improving the automation level of the system.

[0105] The implementation principle of the all-solid-state battery continuous isostatic pressing production system provided in this application embodiment is as follows:

[0106] When the battery cells need to undergo isostatic pressing, they are placed on the incoming material conveyor 07 for feeding. On the incoming material conveyor 07, the barcode scanning and rejection device 09 scans the battery cells and rejects any defective ones. Subsequently, the battery cell transfer device 08 transfers the battery cells from the incoming material conveyor 07 to a temporary storage platform 011 near a set of battery cell loading / unloading devices 03. Simultaneously, the fixture transfer device 01 transfers the battery cell clamping fixture 02; when the battery cell clamping fixture 02 reaches the location of the set of battery cell loading / unloading devices 03, it stops, and the set of battery cell loading / unloading devices 03 assembles the battery cells from the temporary storage platform 011 into the battery cell clamping fixture 02.

[0107] During battery cell assembly, the second pressure plate 022 can be lifted from the first pressure plate 021 using the pressure plate lifting mechanism 031. At this time, the hook gripping assembly 312 first moves a pair of pressure plate hooks 311 away from each other to their maximum distance. Then, the hook lifting assembly 313 drives the first lifting base 314 to descend, causing the pair of pressure plate hooks 311 to move to both ends of the second pressure plate 022. Next, the hook gripping assembly 312 drives the pair of pressure plate hooks 311 to move closer together, so that the pair of pressure plate hooks 311 overlap with the second pressure plate 022. Finally, the hook lifting assembly 313 drives the first lifting base 314 to rise, causing the pair of pressure plate hooks 311 to lift the second pressure plate 022.

[0108] Simultaneously, the battery cell can be clamped by the battery cell clamping mechanism 032 to place the battery cell between the second pressure plate 022 and the first pressure plate 021. At this time, the pressure plate lifting mechanism 031 first lifts the second pressure plate 022, and then the gripper lifting assembly 323 drives the second lifting base 325 to rise and fall, so as to move a pair of battery cell clamping grippers 321 to the same height position as the battery cell to be loaded. Then, the gripper telescopic assembly 324 drives the translation base 326 to move closer to the battery cell, and then the gripper clamping assembly 322 drives a pair of battery cell clamping grippers 321 to move closer to each other, so that a pair of battery cell clamping grippers 321 clamp the battery cell to be loaded. Next, the gripper lifting assembly 323 drives the second lifting base 325 to rise and fall, moving the pair of cell-holding grippers 321 to a height position between the first pressure plate 021 and the second pressure plate 022. Then, the gripper telescopic assembly 324 drives the translation base 326 to move, allowing the pair of cell-holding grippers 321 to extend between the first pressure plate 021 and the second pressure plate 022. Next, the gripper lifting assembly 323 drives the second lifting base 325 to fall, placing the cell on the first pressure plate 021. Then, the gripper holding assembly 322 drives the pair of cell-holding grippers 321 to move away from each other, releasing the cell. Afterward, the pair of cell-holding grippers 321 reset under the drive of the gripper lifting assembly 323 and the gripper telescopic assembly 324, and the pressure plate lifting mechanism 031 lowers the second pressure plate 022.

[0109] Next, the second pressure plate 022 can be lowered by the pressure plate lifting mechanism 031. At this time, the hook lifting assembly 313 first causes the first lifting base 314 to descend, so that a pair of pressure plate hooks 311 lower the second pressure plate 022 to the designated position. Then, the hook clamping assembly 312 drives the pair of pressure plate hooks 311 to move away from each other, so that the pair of pressure plate hooks 311 separate from the second pressure plate 022. Then, the hook lifting assembly 313 drives the first lifting base 314 to rise, so as to reset the pair of pressure plate hooks 311.

[0110] Then, the screw connector 023 is tightened via the screw connector tightening mechanism 033 to lock and fix the first pressure plate 021 and the second pressure plate 022 onto the base plate 024. At this time, the sleeve lifting assembly first causes the sleeve drive to descend, so that the sleeve is fitted over the nut 232. Then, the sleeve drive drives the sleeve to rotate, thereby tightening the nut 232. After that, the sleeve is reset under the drive of the sleeve lifting assembly.

[0111] When the battery cell assembly is complete, the jig loading device moves to a location near the set of battery cell loading / unloading devices 03 and loads the battery cell clamping device with the assembled battery cell into the isostatic pressing device 04. The isostatic pressing device 04 then performs isostatic pressing on the battery cell. When the isostatic pressing is complete, the jig loading device removes the battery cell clamping device from the isostatic pressing device 04 and moves to a location near the set of battery cell loading / unloading devices 03, simultaneously unloading the battery cell clamping device onto the jig transfer device 01. The jig transfer device 01 first transfers the battery cell clamping device to the liquid blowing and drying device 06, where it stops. The liquid blowing and drying device 06 performs liquid blowing and drying on the battery cell clamping jig 02. Subsequently, the jig transfer device 01 transfers the battery cell clamping device to a set of battery cell loading and unloading devices 03 for unloading, and then the set of battery cell loading and unloading devices 03 unloads the battery cell from the battery cell clamping device to the temporary storage platform 011 near the set of battery cell loading and unloading devices 03 for unloading.

[0112] When unloading the battery cell, the screw 023 is loosened by the screw tightening mechanism 033 to facilitate the separation of the first pressure plate 021 and the second pressure plate 022. At this time, the sleeve lifting assembly first causes the sleeve drive to descend so that the sleeve is fitted over the nut 232. Then the sleeve drive drives the sleeve to rotate to loosen the nut 232, and then the sleeve is reset under the drive of the sleeve lifting assembly.

[0113] Then, the second pressure plate 022 can be lifted from the first pressure plate 021 by the pressure plate lifting mechanism 031, and the battery cell can be clamped by the battery cell clamping mechanism 032 to remove the battery cell from between the second pressure plate 022 and the first pressure plate 021 and place it on the temporary storage platform 011. At this time, the pressure plate lifting mechanism 031 first lifts the second pressure plate 022, and then the gripper clamping assembly 322 drives a pair of battery cell clamping grippers 321 to move away from each other to the maximum distance. Then, the gripper lifting assembly 323 drives the second lifting base 325 to rise and fall, so that the pair of battery cell clamping grippers 321 move to the same height position as the battery cell. The gripper telescopic assembly 324 then drives the translation base 326 to move closer to the battery cell, so that the pair of battery cell clamping grippers 321 extend between the first pressure plate 021 and the second pressure plate 022 and extend to both sides of the battery cell. Then, the gripper clamping assembly 322 drives a pair of battery cell clamping grippers 321 to move closer to each other, so that the pair of battery cell clamping grippers 321 clamp the battery cell. Then, the gripper telescopic assembly 324 drives the translation base 326 to move, so that a pair of battery cell gripping grippers 321 retract from between the first pressure plate 021 and the second pressure plate 022. At this time, the pressure plate lifting mechanism 031 lowers the second pressure plate 022, and the fixture transfer device 01 circulates the empty battery cell clamping fixture 02. After that, the gripper lifting assembly 323 drives the second lifting base 325 to rise and fall, so that a pair of battery cell gripping grippers 321 move to the height position where the battery cell is to be unloaded. The gripper telescopic assembly 324 then drives the translation base 326 to move, so that a pair of battery cell gripping grippers 321 move closer to the temporary storage platform 011. Then, the gripper lifting assembly 323 drives the second lifting base 325 to fall, so that the battery cell is placed on the temporary storage platform 011. The gripper gripping assembly 322 then drives a pair of battery cell gripping grippers 321 to move away from each other, so as to release the battery cell.

[0114] When the battery cell is unloaded onto the temporary storage platform 011, the battery cell transfer device 08 transfers the battery cell from the temporary storage platform 011 to the unloading conveyor device 10. On the unloading conveyor device 10, the battery cell drying device 12 first dries the battery cell, and then the testing device 11 tests the battery cell. After the test is completed, the battery cell is unloaded from the unloading conveyor device 10.

[0115] This application, by setting two sets of cell loading and unloading devices 03 on the fixture transfer device 01, assembles the cells into the cell clamping fixture 02 through one set of cell loading and unloading devices 03, and removes the cells from the cell clamping fixture 02 through the other set of cell loading and unloading devices 03, can realize the automatic loading and unloading of cells in the cell clamping equipment. This, combined with the automatic loading and unloading of the cell clamping fixture 02 with the cells assembled in the isostatic pressing device 04, can further improve the automation level of the cells of all-solid-state batteries in the isostatic pressing process, thereby reducing labor costs and improving the working efficiency of the cells during isostatic pressing.

[0116] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0117] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
