[0052] A separation assembly 7 is used to receive the curling assembly 6 holding the cooling bottom plate, and separate the cooling bottom plate on the curling assembly 6;

[0053] A module extrusion assembly 8 is provided with a second quick-change head 81 at the top, and when the module extrusion assembly 8 is combined with the quick-change assembly 51 through the second quick-change head 81, it is used to extrude the battery module in the battery pack after the cooling bottom plate is separated and removed.

[0054] Specifically, the device body frame is composed of a gantry 1 and a workbench 2. The workbench 2 is arranged below the gantry 1 and is used to carry the battery pack to be disassembled. The feeding assembly 3 is used to deliver the battery pack to the workbench 2, and the battery pack is placed with the cooling bottom plate facing upwards, which prepares for the subsequent milling and disassembly operations. The milling assembly 4 is installed on the gantry 1 and can slide along the gantry 1 to adjust its working position. The milling assembly 4 is used to mill the edge of the cooling bottom plate of the battery pack on the workbench 2, with the purpose of weakening the connection strength between the cooling bottom plate and the battery pack, so as to weaken and cut an opening between one side of the battery pack and the cooling bottom plate, and prepare for the subsequent disassembly step.

[0055] More specifically, the milling assembly 4 is self-driven and slidingly installed on the gantry 1, that is, it has the driving ability to displace on the gantry.

[0056] More specifically, the first gantry manipulator 5 is also installed on the gantry 1 and can slide. The end of the first gantry manipulator 5 is equipped with a quick-change assembly 51, which enables the manipulator to quickly change different tool heads to adapt to different operation requirements. In the embodiment of the application, the first gantry manipulator 5 selects to replace the connection curling assembly 6 and the module extrusion assembly 8 to perform the corresponding disassembly operation. The curling assembly 6 is a key component for disassembling the cooling bottom plate, and the top of the curling assembly 6 is provided with a first quick-change head 61, which is quickly connected with the quick-change assembly 51 of the first gantry manipulator 5. When the curling assembly 6 is connected with the first gantry manipulator 5, it can perform curling operation on the cooling bottom plate on the top surface of the battery pack after milling processing, so as to disassemble the cooling bottom plate from the battery pack.

[0057] More specifically, the function of the separation assembly 7 is to receive the curling assembly 6 and the disassembled cooling bottom plate. The separation assembly 7 can separate the cooling bottom plate from the curling assembly 6 to realize automatic collection of the cooling bottom plate.

After milling is completed, the workbench 2 moves to below the first gantry manipulator 5. The first gantry manipulator 5 quickly replaces the connecting curling assembly 6 through the quick-change assembly 51, and curls and peels the cooling bottom plate by using the curling assembly 6. After the curling assembly 6 curls the cooling bottom plate, the first gantry manipulator 5 moves the curling assembly 6 above the separation assembly 7. The separation assembly 7 acts to separate the cooling bottom plate from the curling assembly 6 and collect it. Subsequently, the first gantry manipulator 5 replaces the connecting module extrusion assembly 8 again through the quick-change assembly 51. The module extrusion assembly 8 moves above the workbench 2 to extrude the battery module in the battery pack, so as to separate the battery module from the battery pack. After the separation of the battery module is completed, the disassembly process of the whole battery pack is completed. The motion control of each assembly can be realized by PLC or industrial computer, and the automation monitoring and intelligent adjustment of the disassembly process can be realized by cooperating with sensors and vision systems.

[0060] Through the cooperative work of the above assemblies, the retired lithium-ion power battery pack disassembly integrated equipment of the present application realizes the automatic disassembly of the retired lithium-ion power battery pack, especially realizes the removal of the cooling bottom plate and the automatic removal and collection of the battery module; in addition, the pre-milling of the milling assembly 4 to cut the opening can reduce the difficulty of subsequent curling disassembly and protect the curling assembly 6.

[0079] Specifically, the gantry base frame 11 serves as the basic support structure of the gantry 1, for carrying and fixing the cross beam 12 and the components mounted thereon; the cross beam 12 serves as the mounting carrier of the milling assembly 4 and the first gantry manipulator 5, and is capable of sliding along the gantry base frame 11 under the drive of the first horizontal drive mechanism 13, thereby enabling the milling assembly 4 and the first gantry manipulator 5 to be precisely positioned and moved in the horizontal direction.

[0080] More specifically, the first horizontal drive mechanism 13 is configured to control the sliding speed and position of the cross beam 12 on the gantry base frame 11, ensuring that the milling assembly 4 and the first gantry manipulator 5 can be precisely and reliably moved on the gantry 1, thereby providing a structural basis for the automated operation of the retired lithium-ion power battery pack disassembly integrated equipment.

[0081] In some preferred embodiments, the milling assembly 4 comprises a second gantry manipulator 41 and a milling mechanism 42, and the milling mechanism 42 is mounted at the end of the manipulator of the second gantry manipulator 41.

[0082] Specifically, the milling mechanism 42 can be a high-speed milling head, a micro milling cutter, or a laser milling device, etc., for realizing the precise milling of the edge of the battery pack cooling base plate. The second gantry manipulator 41 and the milling mechanism 42 are fixedly connected through flanges, quick clamps, or bolt connections, etc., so that the milling mechanism 42 can be stably mounted at the end of the manipulator of the second gantry manipulator 41 and move with the second gantry manipulator 41. The second gantry manipulator 41 can be equipped with sensors, such as force sensors, displacement sensors, or vision sensors, etc., for real-time monitoring of the milling force, milling position, and milling effect, thereby realizing precise control and quality assurance of the milling process.

[0083] More specifically, by controlling the second gantry manipulator 41 and the first horizontal drive mechanism 13, the milling mechanism 42 can be precisely moved to a predetermined position of the edge of the battery pack cooling base plate. The second gantry manipulator 41 drives the milling mechanism 42 to mill along the edge of the cooling base plate according to the preset milling path, so as to form an opening between the side of the battery pack body and the cooling base plate.

[0084] In some preferred embodiments, the first gantry manipulator 5 and the second gantry manipulator 41 each comprise a second horizontal drive mechanism 52 and a second lifting drive mechanism 53.

[0085] The second lifting drive mechanism 53 is slidingly mounted on the cross beam 12, and the second horizontal drive mechanism 52 is configured to drive the second lifting drive mechanism 53 to slide on the cross beam 12, and the sliding direction is perpendicular to the sliding direction of the cross beam 12 on the gantry base frame 11, and the lifting active end of the second lifting drive mechanism 53 is the end of the manipulator.

[0086] Specifically, the second lifting driving mechanism 53 is slidingly installed on the cross beam 12, allowing the second lifting driving mechanism 53 to move along the length direction of the cross beam 12. The second horizontal driving mechanism 52 is used to drive the second lifting driving mechanism 53 to slide on the cross beam 12, and the sliding direction is perpendicular to the sliding direction of the cross beam 12 on the gantry base 11, which means that the second lifting driving mechanism 53 can slide in a direction perpendicular to the movement direction of the cross beam 12. The lifting active end of the second lifting driving mechanism 53 serves as the mechanical hand end, which is used to install the corresponding milling mechanism 42 or quick-change assembly 51. Thus, the gantry mechanical hand has two directions of movement freedom, and can realize precise movement in both horizontal and lifting directions.

[0087] More specifically, the cooperative work of the two driving mechanisms in combination with the gantry 1 enables the mechanical hand end to accurately reach the target position in the three-dimensional space, so that the milling assembly 4 and the quick-change assembly 51 can accurately reach the corresponding working position, ensuring the precision and efficiency of the milling operation and assembly replacement, and ultimately improving the degree of automation and disassembly precision of the battery pack disassembly.

[0088] In some preferred embodiments, the curling assembly 6 includes a third bracket 62, a curling roller 63, and a curling motor 64. The first quick-change head 61 is fixed on the top of the third bracket 62, the curling roller 63 is rotatably installed on the bottom of the third bracket 62, and the curling motor 64 is installed on one side of the third bracket 62, used to drive the curling roller 63 to rotate and curl the cooling bottom plate of the top surface of the battery pack after milling processing.

[0089] Specifically, the third bracket 62 serves as a support structure for fixing the first quick-change head 61 and installing the curling roller 63 and the curling motor 64; the first quick-change head 61 enables the curling assembly 6 to be quickly installed on the first gantry mechanical hand 5, facilitating quick and convenient tool replacement; the curling roller 63 is used to contact and curl the cooling bottom plate; and the curling motor 64 provides power to drive the curling roller 63 to rotate and realize curling of the cooling bottom plate.

[0090] More specifically, the curling assembly 6 is quickly assembled with the quick-change assembly 51 at the end of the first gantry robot 5 through the first quick-change head 61, so that the curling assembly 6 can be driven by the first gantry robot 5 to above the battery pack on the workbench 2. After the milling assembly 4 completes the milling process of the edge of the cooling bottom plate of the battery pack, the first gantry robot 5 drives the curling assembly 6 to move to the milling area, and the curling roller 63 is in contact with the edge of the cooling bottom plate. The curling motor 64 is started to drive the curling roller 63 to rotate, and the curling roller 63 exerts a curling force on the edge of the cooling bottom plate during rotation, so that the edge of the cooling bottom plate with an opening is plastically deformed to gradually tear the edge connected with the battery pack body and curl upward, until the entire cooling bottom plate is completely separated from the battery pack body. After curling is completed, the first gantry robot 5 moves the curling assembly 6 to the separation assembly 7 to remove the cooling bottom plate by using the separation assembly 7.

[0091] More specifically, the rotation direction of the curling roller 63 is set to an upward curling direction, so as to curl the cooling bottom plate upward, which is more conducive to the separation of the cooling bottom plate from the battery pack.

[0092] In some preferred embodiments, the curling roller 63 is provided with a plurality of flaps along its axial direction (not shown in the figure), and the cooling bottom plate on the top surface of the battery pack is provided with a plurality of insertion holes (not shown in the figure), and the curling roller 63 is inserted into the insertion holes and rotated to curl the cooling bottom plate on the top surface of the battery pack after the milling process.

[0093] Specifically, the flaps can be strip-shaped protrusions designed to be structures matched with the insertion holes on the top surface of the battery pack, so as to be inserted into the insertion holes of the cooling bottom plate. The strip-shaped protrusions can extend parallel to the axial direction of the curling roller 63, or form a certain angle with the axial direction. The number of flaps can be determined according to the size of the curling roller 63 and the distribution density of the insertion holes on the cooling bottom plate, so as to ensure that the flaps can fully match the insertion holes when the curling roller 63 curls the cooling bottom plate, and realize stable curling.

[0094] More specifically, for the plurality of insertion holes on the cooling bottom plate on the top surface of the battery pack, the insertion holes are designed to be structures matched with the flaps on the curling roller 63.

[0095] More specifically, the length and width of the flap are slightly smaller than the length and width of the insertion hole, to ensure that the flap can be smoothly inserted and have a certain activity space. Thus, through the cooperation of the flap and the insertion hole, effective connection and force transmission between the crimping roller 63 and the cooling bottom plate can be achieved, so that the crimping action is more accurate and controllable, and it is ensured that the cooling bottom plate can be smoothly crimped and removed. When the crimping assembly 6 is working, the first gantry manipulator 5 drives the crimping assembly 6 to move above the battery pack. The crimping roller 63 rotates under the drive of the crimping motor 64, the flap is aligned with the insertion hole on the cooling bottom plate, then the first gantry manipulator 5 drives the crimping roller 63 to descend to insert the flap into the insertion hole, and then the crimping roller 63 rotates under the drive of the crimping motor 64, at the same time, the first horizontal drive mechanism 13 drives the cross beam 12 connected with the first gantry manipulator 5 to move, so as to apply a crimping force to the cooling bottom plate, crimp the cooling bottom plate from the top surface of the battery pack, and gradually remove the cooling bottom plate. The cooperation of the flap and the insertion hole enables the crimping roller 63 to more effectively fix and crimp the cooling bottom plate during crimping, avoids the occurrence of slipping or deviation, ensures the crimping efficiency and effect, and finally realizes the effective removal of the cooling bottom plate.

[0096] In some preferred embodiments, the crimping assembly 6 further comprises a pressure roller 65 and an elastic member 66, the pressure roller 65 is installed on the third support 62 in a lifting manner, and the elastic member 66 is arranged on the third support 62 and presses the top surface of the shaft end of the pressure roller 65 at the bottom, so as to press the battery module exposed on the top surface of the battery pack after the cooling bottom plate is removed.

[0097] Specifically, the pressure roller 65 is installed on the third support 62 in a lifting manner, and the bottom of the pressure roller 65 is pressed against the top surface of the shaft end of the pressure roller 65 by the elastic member 66, so that the bottom of the pressure roller 65 can press the battery module exposed on the top surface of the battery pack after the cooling bottom plate is removed.

[0098] More specifically, the pressure roller 65 is a cylindrical roller, and the material thereof can be an elastic material such as rubber or plastic, so as to avoid damaging the battery module.

[0099] More specifically, the lifting installation structure of the pressure roller 65 can adopt the cooperation of a sliding rail and a sliding block, or the cooperation of a shaft end and a strip-shaped hole, so that the pressure roller 65 can move vertically on the third support 62. The elastic member 66 can be a compression spring, the upper end of the compression spring is fixed on the third support 62, and the lower end abuts against the top surface of the shaft end of the pressure roller 65; through the pre-tightening force of the elastic member 66, the pressure roller 65 can always maintain the pressing force on the battery module, so as to avoid the displacement or lifting of the battery pack during the crimping and removal of the cooling bottom plate by the crimping roller 63, and ensure that the crimping and removal process of the cooling bottom plate can be smoothly performed.

[0100] In some preferred embodiments, the pressure roller 65 comprises a rubber-coated roller.

[0101] Specifically, the compression roller 65 adopts the rubber-coated roller, which can effectively avoid the damage to the battery module during the process of rolling and compressing the battery pack.

[0102] In some preferred embodiments, the third support 62 comprises a top plate 621, two side plates 622 and two third horizontal driving mechanisms 623 installed on both sides of the top plate 621 and used for driving the two side plates 622 to move towards or away from each other. The crimping motor 64 is installed on one of the side plates 622, and the other side plate 622 is provided with a first shaft hole. The crimping roller 63 is rotatably installed on the side plate 622 by inserting one shaft end into the first shaft hole and buckling the other shaft end on the output end of the crimping motor 64.

[0103] Specifically, the two third horizontal driving mechanisms 623 are installed on both sides of the top plate 621 and used for driving the two side plates 622 to move towards or away from each other, thereby adjusting the distance between the two side plates 622. The crimping motor 64 is installed on one of the side plates 622 and provides power for the rotation of the crimping roller 63. The other side plate 622 is provided with a first shaft hole, and one shaft end of the crimping roller 63 is inserted into the first shaft hole, and the other shaft end is connected to the output end of the crimping motor 64 by buckling. This structure enables the crimping roller 63 to be stably rotatably installed between the two side plates 622, ensuring the stability and reliability of the crimping roller 63 during the crimping and removal of the cooling bottom plate.

[0104] More specifically, in this embodiment, the shaft end of the crimping roller 63 is quickly installed by the insertion fit with the shaft hole and the buckling fit with the output end of the motor. After the crimping roller 63 completes the crimping and removal of the cooling bottom plate, the crimping assembly 6 is moved above the separating assembly 7 under the driving of the first gantry robot 5 and the first horizontal driving mechanism 13, and is released from the shaft hole and the output end of the crimping motor 64 under the away movement of the side plate 622 driven by the third horizontal driving mechanism 623 to fall into the separating assembly 7, so that the separating assembly 7 can receive the crimping roller 63 of the crimping assembly 6 holding the cooling bottom plate to separate the cooling bottom plate from the crimping roller 63 of the crimping assembly 6.

[0105] More specifically, the above structure realizes the quick installation and release of the crimping roller 63, so that the crimping roller 63 can be released from the crimping assembly 6 to the separating assembly 7 for the separation and collection of the cooling bottom plate, having the advantages of high automation and high integration.

[0106] In some preferred embodiments, the separating assembly 7 comprises a second base frame 71, a separating box 72 and a fourth horizontal driving mechanism 73, the separating box 72 is slidingly installed on the second base frame 71 for receiving the curling roller 63 holding the cooling bottom plate in the curling assembly 6, and the fourth horizontal driving mechanism 73 is installed on the second base frame 71 for driving the separating box 72 to move horizontally on the second base frame 71 so that the cooling bottom plate is separated from the curling roller 63 and falls into the separating box 72.

[0107] Specifically, the separating box 72 is slidingly installed on the second base frame 71 for receiving the curling roller 63 holding the cooling bottom plate in the curling assembly 6 and finally collecting the separated cooling bottom plate, realizing automatic collection of the cooling bottom plate. The fourth horizontal driving mechanism 73 is installed on the second base frame 71 for driving the separating box 72 to move horizontally on the second base frame 71.

[0108] More specifically, during operation, the curling roller 63 holding the cooling bottom plate is released to fall onto the separating box 72 under the unlocking action of the third horizontal driving mechanism 623, and one end is connected to the second base frame 71, and the fourth horizontal driving mechanism 73 drives the separating box 72 to move horizontally, the horizontal movement of the separating box 72 causes the cooling bottom plate to move relative to the curling roller 63, thereby peeling the cooling bottom plate from the curling roller 63 and falling into the separating box 72, realizing automatic separation of the cooling bottom plate.

[0109] It should be noted that after the separation and collection of the cooling bottom plate are completed, the top plate 621 is moved again above the curling roller 63 and is reset by the third horizontal driving mechanism 623 to quickly load the curling roller 63 again.

[0110] More specifically, through the arrangement of the separating assembly 7, the cooling bottom plate can be automatically separated from the curling assembly 6 and collected without manual operation, improving the disassembly efficiency and automation level.

[0111] In some preferred embodiments, as shown in Figure 7 The second base frame 71 has a first clamping groove at the top of one side, and the curling roller 63 has an annular groove at one end of the shaft which cooperates with the first clamping groove.

[0112] Specifically, the annular groove is designed to fit the first clamping groove, when the curling roller 63 moves to the separating assembly 7, the annular groove at the end of the shaft of the curling roller 63 is limited to fit the first clamping groove of the second base frame 71, and the first clamping groove serves as a containing structure for the end of the shaft of the curling roller 63. The curling roller 63 is correctly aligned and supported during the separation process. Secondly, during the horizontal movement of the separating box 72, the curling roller 63 is supported based on the first clamping groove of the second base frame 71, and can maintain a horizontal state, ensuring that the separating box 72 can smoothly separate the cooling bottom plate.

[0113] More specifically, the shape of the first clamping groove is designed as a U-shaped groove or a V-shaped groove to facilitate the insertion and positioning of the shaft end annular groove of the curling roller 63.

[0114] In some preferred embodiments, the retired lithium-ion power battery pack disassembly and integration equipment also comprises a tool placing rack 9 arranged below the first gantry robot 5, which is used to place the curling assembly 6 and / or the module extrusion assembly 8 that are not combined with the first gantry robot 5.

[0115] Specifically, the tool placing rack 9 is arranged below the first gantry robot 5 to store the components that are not currently used by the first gantry robot 5. When the first gantry robot 5 needs to switch from the curling assembly 6 to the module extrusion assembly 8, the curling assembly 6 is removed by the first gantry robot 5 and placed on the tool placing rack 9, and then the module extrusion assembly 8 is quickly installed from the tool placing rack 9 to perform subsequent processes.

[0116] More specifically, the tool placing rack 9 provides a storage position for the components during tool switching, so that the unused components can be safely and stably placed, avoiding damage or safety hazards caused by random placement of the components, ensuring the cleanliness of the work area, and improving the convenience and efficiency of equipment operation.

[0117] In some preferred embodiments, after the separation assembly 7 completes the separation of the cooling bottom plate, the first gantry robot 5 first transfers the curling assembly 6 to the tool placing rack 9, and then switches and connects the module extrusion assembly 8 through the second quick-change head 81 and the quick-change assembly 51.

[0118] Specifically, after the curling assembly 6 completes the removal of the cooling bottom plate and the separation assembly 7 completes the separation of the cooling bottom plate, the curling assembly 6 is again combined with the curling roller 63, the first gantry robot 5 moves the curling assembly 6 to the tool placing rack 9, controls the quick-change assembly 51 to separate from the curling assembly 6, and places the curling assembly 6 on the tool placing rack 9. Then, the first gantry robot 5 moves to the module extrusion assembly 8, quickly combines with the module extrusion assembly 8 through the quick-change assembly 51, grabs the module extrusion assembly 8, and then uses the module extrusion assembly 8 to extrude the battery modules in the battery pack after the cooling bottom plate is removed. After completing the work of the curling assembly 6, the first gantry robot 5 can quickly switch to connection with the module extrusion assembly 8 using the tool placing rack 9, which shortens the tool switching time and ensures the continuous and efficient operation of the battery pack disassembly and integration equipment.

[0119] In some preferred embodiments, the module extrusion assembly 8 comprises a fourth support 82, a driving plate 83, a third lifting driving mechanism 84 and a plurality of pressing blocks 85, the driving plate 83 is installed on the fourth support 82 in a lifting manner, the driving plate 83 is provided with a plurality of adjusting grooves arranged in an inclined manner, the pressing blocks 85 are a plurality of and are installed on the bottom of the fourth support 82 in a horizontal sliding manner, one side of each of the pressing blocks 85 is provided with a corresponding insertion strip installed in the adjusting groove in a sliding manner, and the third lifting driving mechanism 84 is used to drive the driving plate 83 to move up and down on the fourth support 82 to drive the plurality of pressing blocks 85 to move in a converging or expanding manner in the horizontal direction; wherein the second quick-change head 81 is fixed on the top of the fourth support 82.

[0120] Specifically, the adjusting grooves are arranged in an inclined manner, so that the lifting movement of the driving plate 83 can be converted into the horizontal movement of the pressing blocks 85, and the sliding cooperation between the insertion strips and the adjusting grooves realizes the conversion and transmission of the movement direction.

[0121] More specifically, the number of the pressing blocks 85 can be adjusted according to the size and shape of the battery module to ensure uniform extrusion of the battery module and realize clamping and extraction. The third lifting driving mechanism 84 can adopt a gas cylinder, a hydraulic cylinder or a screw nut mechanism, etc. to provide power for driving the driving plate 83 to lift. The bottom of the pressing block 85 can be provided with a material with a large friction coefficient, so that these materials extrude the side surface of the battery module by aligning the side surface, for example, rubber, to increase the friction between the battery module and prevent the battery module from sliding during extrusion separation.

[0122] More specifically, when the module extrusion assembly 8 works, first, the module extrusion assembly 8 is moved above the battery module to be extruded, and the pressing blocks 85 are aligned with the side surface of the battery module. Then, the third lifting driving mechanism 84 drives the driving plate 83 to move downward. During the downward movement of the driving plate 83, the adjusting grooves drive the insertion strips to slide, the insertion strips drive the pressing blocks 85 to move horizontally and converge, and the convergence of the pressing blocks 85 is realized. During the convergence of the pressing blocks 85, extrusion force is applied to the side surface of the battery module to extrude the battery module from the battery pack. Conversely, when the distance between the pressing blocks 85 needs to be adjusted to adapt to battery modules of different sizes, the third lifting driving mechanism 84 can be controlled to drive the driving plate 83 to move upward, during the upward movement of the driving plate 83, the adjusting grooves reversely drive the insertion strips to slide, the insertion strips drive the pressing blocks 85 to move horizontally and expand outward, and the expansion of the pressing blocks 85 is realized. Thus, the distance between the pressing blocks 85 can be adjusted to adapt to battery modules of different sizes, realizing the universality of the module extrusion assembly 8, while avoiding the low efficiency of manual disassembly and the potential damage to the battery module, improving the automation level and efficiency of the battery module disassembly.

[0123] More specifically, by designing the inclination angle of the adjusting grooves, the converging or expanding speed and stroke of the pressing blocks 85 can be adjusted to meet the extrusion requirements of different battery modules.

[0124] In some preferred embodiments, the quick-change assembly 51 is aligned and connected to the first quick-change head 61 or the second quick-change head 81 via a positioning pin 511, and is fixed based on expansion adsorption.

[0125] Specifically, the first fast head changer 61 and the second fast head changer 81 have the same structure; such as Figure 4 As shown, both the quick-change assembly 51 and the corresponding quick-change head are provided with compressed air connectors 512, which are used to introduce compressed air to expand the expansion body at the contact surface of the quick-change assembly 51 and the quick-change head to lock their positional relationship. The positioning pin 511 is used for guiding and positioning before locking to ensure that the quick-change assembly 51 and the quick-change head can be accurately connected for quick installation.

[0126] In some preferred embodiments, such as Figure 2 and Figure 5 As shown, there are two first gantry robots 5, two module extrusion components 8, and two first quick-change heads 61 provided in the coiling component 6.

[0127] Specifically, by setting two first gantry robots 5 to connect the curling assembly 6 with two first quick-change heads 61, the stability and levelness of the curling assembly 6 during the curling process can be guaranteed, ensuring that the curling assembly 6 can smoothly and accurately complete the curling and removal of the cooling top plate 621.

[0128] More specifically, by setting two first gantry robots 5 to connect to two module extrusion components 8 respectively, it is possible to simultaneously perform extrusion operations on both sides of the battery module, so as to ensure that both sides of the battery module can be extruded and fixed by the two module extrusion components 8 at the same time, so as to smoothly separate them from the battery pack body.
