[0028] Please refer to Figures 1-2 The application provides a disassembling and stacking device 1000, which comprises a liquid injection tray 100, a rack 200, a lifting mechanism 300 and a grabbing mechanism 400. The liquid injection tray 100 comprises a main plate 110, a guide column 111 and a guide sleeve 112. The guide column 111 is arranged on the top surface of the main plate 110, and the guide sleeve 112 is arranged on the bottom surface of the main plate 110 in correspondence with the guide column 111. When two main plates 110 are stacked on each other, the guide column 111 of one main plate 110 is connected with the guide sleeve 112 of the other main plate 110. The rack 200 is provided with a disassembling and stacking station 210 and a transfer station 220. The lifting mechanism 300 is arranged on the disassembling and stacking station 210 and is used to drive the liquid injection tray 100 to move in the vertical direction. The grabbing mechanism 400 comprises a first guide rail 410 and a mechanical hand 420. The first guide rail 410 is arranged on the top of the rack 200, and the mechanical hand 420 is movably connected to the first guide rail 410. The mechanical hand 420 can be moved to align with the disassembling and stacking station 210 or the transfer station 220 along the first guide rail 410. The mechanical hand 420 is also used to move in the vertical direction and clamp or release the liquid injection tray 100.

[0029] The trays used in related technologies cannot be stacked, which forces a single tray to be placed into the battery tank during pressurization. This results in low battery processing efficiency and makes it difficult to meet the demands of high-efficiency production. Please refer to... Figures 3-4 By setting guide posts 111 on the top surface of the main board 110 of the injection tray 100 and guide sleeves 112 at corresponding positions on the bottom surface of the main board 110, when the injection trays 100 are stacked, the guide posts of the lower injection tray 100 are aligned with the guide sleeves 112 of the upper injection tray 100. This allows for the stable positioning and stacking of multiple injection trays 100, enabling simultaneous pressurization of multiple batteries during a single filling, thus increasing the efficiency of battery filling and pressurization. Therefore, the destacking and destacking device 1000 provided in this application, by setting a destacking and destacking station 210 and a transfer station 220 on the frame 200, and providing a lifting mechanism 300 to cooperate with the gripping mechanism 400, effectively reduces the operational difficulty of the device and improves the efficiency of stacking and destacking the injection trays 100.

[0030] Because the injection trays 100 need to be stacked, the overall height of the stacked layers of injection trays 100 changes with the number of injection trays 100 stacked during the stacking and destacking processes. Therefore, the robot arm 420 needs to adjust its movement distance (e.g., the distance the robot arm 420 descends or rises) according to the change in stacking height. This undoubtedly increases the complexity of the equipment design and the difficulty of control, and the frequent adjustment of the robot arm 420's movement path also leads to reduced work efficiency. Therefore, by setting up a lifting mechanism 300, the overall height of the stacked injection trays 100 can be matched with the movement stroke of the robot arm 420 by lifting or lowering the stacked injection trays 100. This ensures that the injection trays 100 are within the movement stroke range of the robot arm 420, guaranteeing that the injection trays 100 can be gripped or released by the robot arm 420 at the destacking station 210. Simultaneously, it simplifies the movement path of the robot arm 420, reduces the difficulty of controlling the robot arm 420's movement process, and improves the efficiency of stacking and destacking operations.

[0031] When the liquid injection tray 100 needs to be stacked, the liquid injection tray 100 is conveyed from the unstacking device 1000 to the transfer station 220, the mechanical arm 420 moves to the transfer station 220 along the first guide rail 410 and lowers to clamp the liquid injection tray 100, then the mechanical arm 420 moves to the unstacking station 210 along the first guide rail 410 and lowers to release the liquid injection tray 100 on the lifting mechanism 300; when the liquid injection tray 100 needs to be unstacked, the mechanical arm 420 moves to the lifting mechanism 300 along the first guide rail 410 and lowers to clamp the liquid injection tray 100, then the mechanical arm 420 moves to the transfer station 220 along the first guide rail 410 and lowers to release the liquid injection tray 100. During the stacking and unstacking of the liquid injection tray 100, the lifting mechanism 300 can drive the liquid injection tray 100 to move in the vertical direction according to the stacking height of the received liquid injection tray 100, so as to ensure that the mechanical arm 420 can successfully clamp or release the liquid injection tray 100, and can reduce the change of the moving stroke of the mechanical arm 420 in the vertical direction, and reduce the control difficulty of the movement of the mechanical arm 420.

[0032] Optionally, the unstacking station 210 and the transfer station 220 are arranged adjacently.

[0033] Optionally, the bottom surface of the main plate 110 is provided with at least two positioning flanges 114, when the liquid injection tray 100 is transported by the fork, the fork can position the liquid injection tray 100 through the positioning flanges 114.

[0034] Please refer to Figure 5 In some embodiments, the lifting mechanism 300 comprises a driving member 310 and a supporting plate 320, the supporting plate 320 is used to carry the liquid injection tray 100, and the driving member 310 is used to drive the supporting plate 320 to move downward when the liquid injection tray 100 is stacked, and the driving member 310 is also used to drive the supporting plate 320 to move upward when the liquid injection tray 100 is unstacked.

[0035] The moving stroke of the mechanical arm 420 at the unstacking station 210 is affected by the overall height of the stacked liquid injection tray 100, when the liquid injection tray 100 is stacked, the stacking height of the liquid injection tray 100 carried by the supporting plate 320 will increase with the stacking process, in order to avoid that the stacking of the liquid injection tray 100 occupies the moving space of the mechanical arm 420 in the vertical direction, the supporting plate 320 needs to be driven to move downward, so as to ensure that the moving stroke of the mechanical arm 420 is not affected; when the liquid injection tray 100 is unstacked, the stacking height of the liquid injection tray 100 carried by the supporting plate 320 will decrease with the unstacking process, in order to ensure that the moving path of the mechanical arm 420 can reach the liquid injection tray 100, the supporting plate 320 needs to be driven to move upward, so as to ensure that the mechanical arm 420 can successfully clamp the liquid injection tray 100 carried by the supporting plate 320.

[0036] Optionally, the lifting mechanism 300 further comprises a lifting screw 330, and the supporting plate 320 is provided with a connector 322, and the connector 322 is provided with a hole allowing the lifting screw 330 to pass through. By passing the lifting screw 330 through the hole of the connector 322, the supporting plate 320 can be connected with the lifting screw 330, and driving the rotation of the lifting screw 330 can drive the supporting plate 320 to move up and down. The lifting screw 330 has simple structure and is convenient to install, and has stable operation process and can bear large weight, thereby ensuring the stability of the supporting plate 320 during the movement of the supporting plate 320 on the liquid injection tray 100.

[0037] Optionally, the lifting mechanism 300 further comprises a transmission device 350, and the driving member 310 and the transmission device 350 are arranged on the side of the supporting plate 320. One end of the transmission device 350 is connected with the driving member 310, and the other end is connected with the lifting screw 330. The driving member 310 drives the rotation of the lifting screw 330 through the transmission device 350. The transmission device 350 can optimize the layout of each component of the lifting mechanism 300, and a single driving member 310 can drive multiple lifting screws 330.

[0038] In some embodiments, when the unstacking station 210 is stacking, the driving member 310 drives the supporting plate 320 to move downward by a distance of the thickness of one liquid injection tray 100. When the unstacking station 210 is unstacking, the driving member 310 drives the supporting plate 320 to move upward by a distance of the thickness of one liquid injection tray 100.

[0039] It can be understood that when the liquid injection tray 100 is stacked, the height of the stack of the liquid injection tray 100 carried by the supporting plate 320 increases with the stacking process. The increased height corresponds to the thickness of one liquid injection tray 100. To simplify the movement path of the mechanical hand 420, the supporting plate 320 can be driven to move downward by the thickness of one liquid injection tray 100, so that the movement distance of the mechanical hand 420 in the unstacking station 210 remains unchanged. When the liquid injection tray 100 is unstacked, the height of the stack of the liquid injection tray 100 carried by the supporting plate 320 decreases with the unstacking process. The decreased height corresponds to the thickness of one liquid injection tray 100. To simplify the movement path of the mechanical hand 420, the supporting plate 320 can be driven to move upward by the thickness of one liquid injection tray 100, so that the movement distance of the mechanical hand 420 in the unstacking station 210 remains unchanged. Specifically, when the unstacking station 210 is stacking, the supporting plate 320 moves downward by a distance of the thickness of one liquid injection tray 100 during the movement of the mechanical hand 420 from the unstacking station 210 to the transfer station 220. When the unstacking station 210 is unstacking, the supporting plate 320 moves upward by a distance of the thickness of one liquid injection tray 100 during the movement of the mechanical hand 420 from the unstacking station 210 to the transfer station 220.

[0040] In some embodiments, the lifting mechanism 300 further comprises a second guide rail 340 extending in the vertical direction, and the supporting plate 320 is movably connected to the second guide rail 340 and can move along the second guide rail 340 in the vertical direction.

[0041] By extending the second guide rail 340 in the vertical direction, the supporting plate 320 can move along the second guide rail 340 while moving along the original moving track, further enhancing the reliability and stability of the movement of the supporting plate 320.

[0042] Optionally, the lifting mechanism 300 comprises a lifting screw 330, and the second guide rail 340 and the lifting screw 330 are used in cooperation to jointly define the moving path of the supporting plate 320. When at least a part of the supporting plate 320 moves up and down along the lifting screw 330, the other part of the supporting plate 320 can be simultaneously driven to move up and down along the second guide rail 340, thereby realizing the movement of the entire supporting plate 320, while ensuring the stability of the lifting, the manufacturing cost can also be saved.

[0043] Optionally, the supporting plate 320 is provided with a sliding block 323 which can be connected with the second guide rail 340 to complete the connection between the supporting plate 320 and the second guide rail 340; or the supporting plate 320 can be formed with a connecting part in the shape of the second guide rail 340, and the connecting part is connected with the second guide rail 340 to enable the supporting plate 320 to move in the vertical direction along the second guide rail 340.

[0044] In some embodiments, the surface of the supporting plate 320 for supporting the liquid injection tray 100 is provided with a positioning pin 321, and when the liquid injection tray 100 is placed on the supporting plate 320, the positioning pin 321 can be connected with the guide sleeve 112.

[0045] By providing the positioning pin 321 on the surface of the supporting plate 320 for supporting the liquid injection tray 100, the liquid injection tray 100 can be positioned when placed on the supporting plate 320, avoiding displacement and falling of the liquid injection tray 100, and since the positioning pin 321 can be connected with the guide sleeve 112 on the bottom surface of the main plate 110 of the liquid injection tray 100, no additional components are needed to achieve effective positioning, thereby saving the manufacturing cost of the device.

[0046] Optionally, four positioning pins 321 corresponding to the guide sleeves 112 are provided on the supporting plate 320 according to the size of the liquid injection tray 100, or the number of positioning pins 321 can be less than four.

[0047] Please refer to Figures 1-2 In some embodiments, the transfer station 220 is provided with a conveying mechanism 500, and the conveying mechanism 500 comprises a conveying belt 510, one end of the conveying belt 510 extends towards the unstacking station 210, and the conveying belt 510 is used to drive the liquid injection tray 100 to move.

[0048] To complete the stacking and unstacking of the liquid injection tray 100, the mechanical arm 420 needs to move between the unstacking and stacking station 210 and the transfer station 220, so the mechanical arm 420 needs to spend a certain amount of time to complete the clamping and releasing of a single liquid injection tray 100. To ensure the smoothness of the process of the unstacking and stacking device 1000, a conveying mechanism 500 and a conveying belt 510 can be arranged at the transfer station 220, and one end of the conveying belt 510 extends towards the unstacking and stacking station 210. Since the liquid injection tray 100 can move along the conveying belt 510, by placing the liquid injection trays 100 on the conveying belt 510 at fixed intervals, the conveying frequency of the liquid injection tray 100 can be matched with the working speed of the mechanical arm 420, ensuring that the mechanical arm 420 can grasp and release each liquid injection tray 100, avoiding the situation that when stacking, the conveying frequency of the liquid injection tray 100 on the transfer station 220 is too fast, resulting in some liquid injection trays 100 being missed, and also avoiding the situation that when unstacking, the conveying frequency of the liquid injection tray 100 on the transfer station 220 is too slow, resulting in the accumulation of liquid injection trays 100 on the transfer station 220.

[0049] In some embodiments, the conveying mechanism 500 includes a positioning and lifting mechanism 520 arranged at one end of the conveying belt 510 close to the unstacking and stacking station 210. When the positioning and lifting mechanism 520 is lifted, it lifts the liquid injection tray 100, and the liquid injection tray 100 and the conveying surface of the conveying belt 510 are separated from each other.

[0050] By arranging the positioning and lifting mechanism 520 on the conveying mechanism 500, when the liquid injection tray 100 moves to the positioning and lifting mechanism 520, the positioning and lifting mechanism 520 limits the movement of the liquid injection tray 100 and lifts the liquid injection tray 100 to a position higher than the conveying belt 510, thereby ensuring that the mechanical arm 420 can accurately and stably clamp or release the liquid injection tray 100. Specifically, when the unstacking and stacking device 1000 performs the stacking function, the liquid injection tray 100 moves along the conveying belt 510 to the positioning and lifting mechanism 520, which can fix the position of the liquid injection tray 100 and lift it upwards, so that the liquid injection tray 100 and the conveying surface of the conveying belt 510 are separated from each other, thereby making the liquid injection tray 100 can be separated from the original conveying path, avoiding the liquid injection tray 100 continuing to move along the conveying belt 510 and falling out of the unstacking and stacking device 1000, at this time the mechanical arm 420 can move above the liquid injection tray 100 to clamp it; when the unstacking and stacking device 1000 performs the unstacking function, the positioning mechanism will be lifted upwards as a preliminary state for receiving the liquid injection tray 100, and after the mechanical arm 420 releases the liquid injection tray 100 on the positioning mechanism, the positioning mechanism will return to the original position, so that the liquid injection tray 100 can be stably placed and then conveyed by the conveying belt 510, avoiding the situation that the liquid injection tray 100 is released on the conveying belt 510 and causes the liquid injection tray 100 to be placed in an unstable state and then be tilted.

[0051] Optionally, the positioning jacking mechanism 520 comprises a pneumatic cylinder, which drives the positioning jacking mechanism 520 to jack up.

[0052] In some embodiments, the conveying mechanism 500 comprises a turning mechanism 530, which is arranged at an end of the conveying belt 510 away from the depalletizing station 210, and is used to turn the liquid injection tray 100 in the horizontal direction.

[0053] When the depalletizing device 1000 needs to be used in cooperation with a product production line, the product production line is generally connected to the transfer station 220 from the side of the transfer station 220, and the turning mechanism 530 can change the moving direction of the liquid injection tray 100, so that when the liquid injection tray 100 is transported from the product production line to the transfer station 220, it can be turned into the conveying belt 510 and moved along the conveying belt 510 towards the depalletizing station 210, or when it is transported from the conveying belt 510 to the product production line, it can be turned into the product production line, thereby improving the degree of automation of battery processing and improving production efficiency.

[0054] Optionally, the turning mechanism 530 can be arranged as a roller.

[0055] Optionally, the turning mechanism 530 comprises a driving member 310 and a plate chain, when the liquid injection tray 100 moves to the turning mechanism 530, the driving member 310 can drive the turning mechanism 530 to turn, and the driving member 310 can also drive the plate chain to move and thereby drive the movement of the liquid injection tray 100; optionally, the driving member 310 can drive the turning mechanism 530 to jack up and lift the liquid injection tray 100, so that the liquid injection tray 100 can be turned again without departing from the original moving track, thereby ensuring the turning stability of the liquid injection tray 100.

[0056] In some embodiments, the rack 200 is provided with a first material receiving port 230 and a second material receiving port 240, the first material receiving port 230 is connected to the transfer station 220, and the second material receiving port 240 is connected to the depalletizing station 210.

[0057] The first receiving port 230 and the second receiving port 240 are arranged on the rack 200, which can facilitate the cooperation of the battery unpacking and stacking device 1000 with other product assembly lines, and improve the automation level of the battery processing flow. When the battery unpacking and stacking device 1000 performs the stacking function, the first receiving port 230 can be connected with a production line for transporting the liquid injection tray 100, and a single liquid injection tray 100 can enter the battery unpacking and stacking device 1000 from the first receiving port 230 and be transported from the transfer station 220 to the unpacking and stacking station 210 by the mechanical arm 420. When the unpacking and stacking station 210 stacks a specified number of liquid injection trays 100, the stacked layers of the liquid injection trays 100 can be transported out of the battery unpacking and stacking device 1000 by a fork or other production line through the second receiving port 240. When the battery unpacking and stacking device 1000 performs the unpacking function, the stacked layers of the liquid injection trays 100 can enter the battery unpacking and stacking device 1000 from the second receiving port 240, and the mechanical arm 420 can transport the liquid injection trays 100 from the unpacking and stacking station 210 to the transfer station 220 one by one, and a single liquid injection tray 100 can be transported out of the battery unpacking and stacking device 1000 by a fork or other production line through the first receiving port 230.

[0058] Optionally, the first receiving port 230 and the second receiving port 240 can be arranged on the same side of the rack 200, or the first receiving port 230 and the second receiving port 240 can be arranged on opposite sides of the rack 200.

[0059] Exemplarily, when the unpacking and stacking station 210 stacks three liquid injection trays 100, the stacked layers of the liquid injection trays 100 can be transported out of the battery unpacking and stacking device 1000 through the second receiving port 240.

[0060] Please refer to Figure 3 In some embodiments, the liquid injection tray 100 comprises a liquid injection plate 120 arranged on the top surface of the main plate 110, the liquid injection plate 120 is provided with a through hole 121, and the guide column 111 is arranged in the through hole 121 when the liquid injection plate 120 is stacked with the main plate 110.

[0061] By positioning and installing the liquid injection plate 120 on the top surface of the main plate 110, the liquid injection plate 120 can play a guiding role in the battery liquid injection process. Using the liquid injection plate 120 to inject liquid into the battery can ensure the accuracy of the injection position, thereby avoiding the performance degradation of the battery caused by the deviation of the injection position. Since the liquid injection plate 120 is provided with the through hole 121 through which the guide column 111 can be arranged, the liquid injection tray 100 can still be stacked by the cooperation of the guide column 111 and the guide sleeve 112 in the case of adding the liquid injection plate 120, and the battery can still ensure the efficiency of the tank pressure in the case of improving the accuracy of the battery liquid injection.

[0062] Optionally, the middle part of the edge of the main plate 110 is provided with a handle 113, or a plurality of handles 113 can be arranged at intervals on the edge of the main plate 110.

[0063] Please refer back to Figure 1 The process of stacking by using the stacking and destacking device 1000 provided in the present application is as follows:

[0064] First, the first receiving port 230 and the second receiving port 240 are arranged on the same side of the rack 200, the liquid injection tray 100 transportation production line is connected to the transfer station 220 through the first receiving port 230, and the transfer station 220 is arranged adjacent to the stacking and destacking station 210. A plurality of liquid injection trays 100 are transported by the production line to the transfer station 220, and when the liquid injection tray 100 passes through the turning mechanism 530 of the transfer station 220, the turning mechanism 530 is lifted upward and turned to the direction in which the stacking and destacking station 210 is arranged. The conveying belt 510 is arranged on both sides of the transfer station 220 and extends to the direction of the stacking and destacking station 210, at this time the plate chain on the turning mechanism 530 can push the liquid injection tray 100 to move forward, so that the liquid injection tray 100 can be engaged with the conveying belt 510 and continue to move to the direction of the stacking and destacking station 210. When the liquid injection tray 100 is completely engaged with the conveying belt 510, the turning mechanism 530 returns to the original position and is ready to receive the next liquid injection tray 100. When the liquid injection tray 100 passes through the positioning and lifting mechanism 520, the positioning and lifting mechanism 520 limits the liquid injection tray 100 and lifts the liquid injection tray 100 upward, at this time the mechanical hand 420 moves to the upper side of the positioning and lifting mechanism 520 and clamps the liquid injection tray 100, and then the mechanical hand 420 moves along the first guide rail 410 to the stacking and destacking station 210, the positioning and lifting mechanism 520 returns to the original position and is ready to receive the next liquid injection tray 100. When the mechanical hand 420 releases the liquid injection tray 100 on the supporting plate 320 of the lifting mechanism 300, the liquid injection tray 100 is positioned with the positioning pin 321 of the supporting plate 320, and in the process that the mechanical hand 420 moves along the first guide rail 410 to the transfer station 220, the supporting plate 320 moves downward by a distance of the thickness of the liquid injection tray 100. Repeat the above process, when the stacking of three liquid injection trays 100 is completed, the stacked layers of the liquid injection tray 100 are transported by the fork from the second receiving port 240 to the outside of the stacking and destacking device 1000.

[0065] Please refer back to Figure 2 The process of destacking by using the stacking and destacking device 1000 provided in the present application is as follows:

[0066] Firstly, the first receiving port 230 and the second receiving port 240 are arranged at opposite sides of the rack 200, the liquid injection tray 100 transportation production line is connected to the transfer station 220 through the first receiving port 230, and the transfer station 220 is arranged adjacent to the unstacking station 210. The stacked layers of the liquid injection tray 100 are transported to the tray plate 320 of the lifting mechanism 300 through the second receiving port 240, the mechanical arm 420 moves to the upper side of the unstacking station 210 along the first guide rail 410 and clamps the liquid injection tray 100, and in the process of moving the mechanical arm 420 to the transfer station 220 along the first guide rail 410, the tray plate 320 moves upward by a distance of the thickness of the liquid injection tray 100. When the mechanical arm 420 moves to the upper side of the positioning and lifting mechanism 520, the positioning and lifting mechanism 520 is in a preliminary state of upward lifting, at this time, the mechanical arm 420 releases the liquid injection tray 100 on the positioning and lifting mechanism 520, and the positioning and lifting mechanism 520 limits the liquid injection tray 100 and returns to the original position at the same time, at this time, the liquid injection tray 100 can be combined with the conveying belt 510 arranged at both sides of the transfer station 220. When the liquid injection tray 100 completely leaves the positioning and lifting mechanism 520, the positioning and lifting mechanism 520 is lifted upward and is ready to receive the next liquid injection tray 100. The conveying belt 510 drives the liquid injection tray 100 to move in a direction away from the unstacking station 210, when the liquid injection tray 100 moves to the turning mechanism 530, the turning mechanism 530 is lifted upward and turns to the direction arranged by the liquid injection tray 100 transportation production line, at this time, the plate chain on the turning mechanism 530 can push the liquid injection tray 100 to move forward, so that the liquid injection tray 100 can enter the liquid injection tray 100 transportation production line through the first receiving port 230 and be transported to the outside of the unstacking device 1000. When the liquid injection tray 100 completely leaves the turning mechanism 530, the turning mechanism 530 returns to the original position and is ready to receive the next liquid injection tray 100.
