Finally, experienced operators separate the battery cells and inspect and classify the individual cells. However, this disassembly and recycling method, due to the structural and material characteristics of new energy batteries, requires high operator experience and poses certain safety risks. Furthermore, manual disassembly is inefficient and incurs high labor costs. Summary of the Invention

Finally, the transfer robot moves the battery cell module after the guard plate is removed to the battery cell cutting detection device, cuts and detects the battery cells of the battery cell module, and classifies the recycling components according to the detection results to achieve complete disassembly and recycling of the new energy battery.

[0093] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0094] Figure 1 Schematic diagram of the structure of a new energy battery disassembly system according to one embodiment of the present invention. Figure 1 In the disassembly system of new energy batteries, the disassembly system may include an online module 01, a busbar milling machine 04, a battery guard plate cutting device 06, a battery guard plate removal device 07, a battery cell cutting detection device 11, a classification and recycling component 10 and a transfer robot 02.

[0095] The online module 01 is used to identify and scan the battery modules to be disassembled, and to transport the battery modules. The busbar milling machine 04 is used to mill the weld points of the busbar of the battery module, the battery guard plate cutting device 06 is used to cut the guard plate of the battery module, and the battery guard plate removal device 07 is used to remove the guard plate of the battery module. The battery cell cutting and detection device 11 is used to cut the battery cells in the battery module and perform performance testing. The classification and recycling component 10 is used to classify the good and bad products after testing. The online module 01, the busbar milling machine 04, the battery guard plate cutting device 06, the battery guard plate removal device 07, the battery cell cutting and detection device 11 and the classification and recycling component 10 are distributed in sequence and form a ring or square. The transfer robot 02 is set inside the ring or square and is used to transfer the battery modules on the online module 01, the busbar milling machine 04, the battery guard plate cutting device 06 and the battery guard plate removal device 07.

[0096] When the new energy battery module needs to be disassembled, the online module 01 transports the battery module to the side wall of the transfer robot 02, and the transfer robot then transfers the battery module to the milling port of the busbar milling machine 04. During the process of the online module 01 transporting the battery module, the model and number of the battery module are scanned and identified, and entered into the system. The busbar milling machine 04 moves the battery module located at the milling port to the position to be milled, and mills the welding points of the busbar on the battery module one by one. After the busbar milling machine 04 completes milling of the battery module, it moves the battery module to the milling port, and the battery module is clamped and transferred to the battery guard plate cutting device 06 by the transfer robot 02. The battery guard plate cutting device 06 cuts the four guard plates of the battery module. After the four guard plates of the battery module are cut, the transfer robot 02 clamps the battery module again and transfers it to the battery guard plate removal device 07, and the battery guard plate removal device 07 removes the four guard plates of the battery module to form a battery cell module. Finally, the transfer robot 02 clamps and transfers the battery cell module to the battery cell cutting and detection device 11. The battery cell cutting and detection device first cuts the batteries on the battery cell module in sequence, and then tests the cut batteries in sequence to determine whether the battery cell is good or defective. The classification and recycling component 10 transports the battery cell to different places based on the detection results of the battery cell to realize the disassembly of the new energy battery.

[0097] During the disassembly of traditional new energy battery modules, manual milling tools are often required to mill the welds on the busbars, then use a cutting knife to cut and remove the guard plates, and finally separate and inspect the individual cells one by one. Due to the structure and material characteristics of new energy batteries, improper operation by operators can easily cause the battery modules to spontaneously combust, resulting in safety accidents. Therefore, manual disassembly methods place high demands on the disassembly personnel. In addition, due to the high requirements and many restrictions on manual operation, manual disassembly is inefficient and the resulting labor costs are also high. In this embodiment of the present invention, the online module 01, busbar milling machine 04, battery guard plate cutting device 06, battery guard plate removal device 07, battery cell cutting and inspection device 11, classification and recycling assembly 10, and transfer robot 02 are used to disassemble new energy batteries, saving labor costs and improving disassembly efficiency. In addition, the overall disassembly system is square or ring-shaped, making the disassembly system highly integrated and occupying a small area overall. The transfer robot 02 is set in the middle of the square or ring, making transportation more convenient. The disassembly system is highly intelligent and has high disassembly precision, which can effectively reduce safety hazards during the disassembly process.

[0098] In this embodiment of the invention, Figure 1 As shown, the new energy battery disassembly system may further include a protective fence 12 and multiple distribution cabinets 03.

[0099] A protective fence 12 surrounds the outside of the on-line module 01, busbar milling machine 04, battery shield cutting device 06, battery shield removal device 07, battery cell cutting and detection device 11, classification and recycling component 10, and transfer robot 02. Multiple distribution cabinets 03 are located outside the protective fence 12 and are connected to the on-line module 01, busbar milling machine 04, battery shield cutting device 06, battery shield removal device 07, battery cell cutting and detection device 11, classification and recycling component 10, and transfer robot 02, respectively.

[0100] The protective fence 12 protects the dismantling equipment within the dismantling system, preventing unauthorized personnel from entering and disrupting the system's normal operation. It also protects against potential safety incidents caused by unauthorized personnel entering. The power distribution cabinet 03 is located outside the protective fence 12, making it easily accessible to maintenance personnel and operators of the equipment, ensuring the system's normal operation.

[0101] In this embodiment of the present invention, in order to improve the precise control capability of relevant personnel over the new energy battery disassembly process, the protective fence 12 is made of transparent material to facilitate intuitive inspection of the battery module disassembly system by external personnel.

[0102] In this embodiment of the invention, Figure 2 As shown, the online module 01 can include a support column 13, a rotating column 14, a steering rod 15, an electric hoist 16, an online base plate 18, two clamping plates 20, a clamping assembly, a conveyor slide 17, a sliding assembly, and a first barcode scanner. Specifically, the electric hoist 16 can include a lifting rope provided at its output end and a pull rope connected to its side wall; the online base plate 18 can include a movable opening 19.

[0103] The support column 13 is positioned outside the protective barrier 12. The rotating column 14 is positioned on the top sidewall of the support column 13, with both ends of the rotating column 14 rotatably connected to the support column 13. One end of the steering rod 15 is vertically connected to the sidewall of the rotating column 14. The sliding assembly is positioned at the bottom of the steering rod 15. The electric hoist 16 is positioned below the steering rod 15 and is slidably connected to the sliding assembly. The upper line base plate 18 is positioned below the electric hoist 16. The lifting rope is connected to the top of the upper line base plate 18, and the upper line base plate 18 has a movable opening 19. Two clamping plates 20 are positioned below the upper line base plate 18. The clamping assembly is positioned within the movable opening 19 and is connected to the two clamping plates 20, which is used to drive the two clamping plates 20 toward or away from each other. The conveyor slide 17 extends through the protective barrier 12. One end of the conveyor slide 17 extends to the side of the transfer robot 02, and the other end of the conveyor slide 17 extends to the side of the support column 13. The first barcode scanner is disposed on the conveying slide 17 and is used to scan and identify the battery module.

[0104] To disassemble a new energy battery module, a worker pulls the electric hoist 16 with a pull rope, rotating the rotating column 14. The rotating column 14 rotates the steering rod 15 and the upper production base plate 18, which then cooperates with the sliding assembly to move the upper production base plate 18 above the battery module. The electric hoist 16 activates and, using the lifting rope, drives the upper production base plate 18 downward, gradually approaching the battery module. When the two clamping plates 20 move to opposite sides of the battery module, the clamping assembly drives the two clamping plates 20 toward each other, clamping the battery module in place. The electric hoist 16 activates and, using the lifting rope, drives the upper production base plate 18 and the battery module upward. The worker pulls the electric hoist 16 with the pull rope, rotating the rotating column 14 and moving the battery module above the other end of the conveyor slide 17. The clamping assembly resets the two clamping plates 20, allowing the battery module to fall above the conveyor slide 17. The conveyor assembly 21 then transports the battery module to the side of the transfer robot 02. During the process of conveying the battery module on the conveyor slide 17, the first barcode scanner scans and records the model and serial number of the battery module, so that relevant personnel can better monitor the disassembly status of the battery module. Using this method of the on-line module 01 to pick up the battery module can automatically clamp and put the battery module near the support column 13 on the line, which is more intelligent and convenient.

[0105] In this embodiment of the present invention, the on-line module 01 may also include a visual detection sensor. Specifically, the visual detection sensor is installed on the electric hoist 16 to accurately detect and identify the position of the battery module near the support column 13, so as to realize intelligent clamping and on-line of the battery module at any position near the support column 13.

[0106] In this embodiment of the present invention, the specific structure of the clamping assembly can be various forms known to those skilled in the art, including but not limited to a cylinder, a ball screw, etc.

[0107] In this embodiment of the present invention, the specific structure of the sliding assembly can be various forms known to those skilled in the art, including but not limited to electric slides driving the electric hoist 16 to move, pneumatic slides driving the electric hoist 16 to move, etc.

[0108] In this embodiment of the present invention, the specific structure of the conveying slide 17 can be various forms known to those skilled in the art, such as a conveyor belt, a transport guide rail, etc. However, in a preferred embodiment of the present invention, considering the stability and efficiency of the conveying, the specific structure of the conveying slide 17 can be as follows: Figure 1 Specifically, Figure 1 In the embodiment, the conveying component may include a conveyor belt.

[0109] In this embodiment of the invention, Figure 3 、 Figure 4 and Figure 5 As shown, the manifold milling machine 04 may include a milling base 22, a first inverted U-shaped support plate 24, a milling box 32, a milling plate, a first robotic arm 31, a milling cutter 38, a first guide assembly 30, a first limiting assembly, a milling assembly 28, a tool changing assembly 29, a conveying assembly 21, and a first waste chip recovery assembly 23. Specifically, the milling base 22 may include a first notch 37; the milling box 32 may include two milling openings.

[0110] A first slot 37 is defined at the top of the milling base 22. The conveying assembly 21 is movable through the portion of the protective barrier 12, with one end of the conveying assembly 21 extending to the milling port of the milling base 22 for transporting the milled busbar. A first inverted U-shaped support plate 24 is disposed at the top of the milling base 22, with two parallel portions of the first inverted U-shaped support plate 24 located on either side of the first slot 37. A milling box 32 is disposed at the top of the milling base 22, partially covering the top of the first slot 37. Milling openings are defined at both the top and bottom of the milling box 32, and a milling plate is disposed within the milling box 32. A first robotic arm 31 is disposed at the top of the milling base 22 and is used to clamp the battery module on one end of the conveying assembly 21 to the top of the milling plate. It is also used to remove the milled busbar from the battery module within the milling box 32 and clamp it to one end of the conveying assembly 21. A milling cutter 38 is disposed above the milling box 32. A first guide assembly 30 is positioned within the first notch 37. The bottom of the milling box 32 is connected to the first guide assembly 30 and is used to drive the milling box 32 along the milling port and below the milling cutter 38. A first stopper assembly is positioned on the inner wall of the milling box 32 to secure the battery modules within the milling box 32. A milling assembly 28 is positioned on the side of the first inverted U-shaped support plate 24 near the milling cutter 38. The milling assembly 28 is connected to the milling cutter 38 and is used to drive the milling cutter 38 toward the battery modules within the milling box 32 and mill all welds on the busbars of the battery modules. A tool changer assembly 29 is positioned on the side of the first inverted U-shaped support plate 24 away from the milling cutter 38 and is used to change the milling cutter 38 according to the size of the welds on the busbars. A first waste chip recovery assembly 23 is positioned within the first notch 37. The milling opening at the bottom of the milling box 32 cooperates with the first waste chip recovery assembly 23 to recover waste chips generated by milling the welds on the busbars.

[0111] When it is necessary to mill the weld points on the busbar of the battery module, the transfer robot 02 clamps the battery module on one end of the conveying slide 17 onto the milling plate inside the milling box 32, and the first limiting assembly limits and fixes the battery module. The first guide assembly 30 starts and drives the milling box 32 and the battery module inside the milling box 32 to move to the bottom of the milling cutter 38. The tool changing assembly 29 replaces the corresponding milling cutter according to the size of the weld points on the busbar in the battery module. The milling assembly 28 starts and controls the milling cutter 38 to mill all the weld points on the busbar. The waste chips generated during the milling process fall along the milling opening at the bottom of the milling box 32 to the inside of the first waste chip recovery assembly 23 to achieve waste chip recovery. After the milling of the battery module is completed, the milling assembly 28 is reset, and the first guide assembly 30 drives the milling box 32 to reset to complete the milling of the busbar of the battery module. After the busbar of the battery module is milled, the first robotic arm 31 removes the busbar inside the milling box 32 from the battery module and clamps it to one end of the conveying assembly 21. The conveying assembly 21 moves the busbar out to a position to be recycled.

[0112] In this embodiment of the present invention, the specific structure of the conveying component 21 can be various forms known to those skilled in the art, such as a conveyor belt, a transport guide rail, etc. However, in a preferred embodiment of the present invention, considering the stability and efficiency of the conveying, the specific structure of the conveying component 21 can be as follows: Figure 3 Specifically, Figure 3 In the embodiment, the conveying component may include a conveyor belt.

[0113] In this embodiment of the present invention, the specific structure of the first guide assembly 30 can be various forms known to those skilled in the art, including but not limited to a cylinder, a ball screw, etc.

[0114] In this embodiment of the present invention, the specific structure of the first limiting assembly can be various forms known to people in this field, such as a cylinder driving the limiting plate to clamp the battery module, and two screws with opposite rotation directions rotating to drive the limiting plates connected to the corresponding threads to move closer to each other.

[0115] In this embodiment of the invention, Figure 3 and Figure 4 As shown, the milling assembly 28 may include a first moving module 25 , a second moving module 26 and a second servo motor 27 .

[0116] The first movable module 25 is vertically mounted on the sidewall of the first inverted U-shaped support plate 24. The second movable module 26 is horizontally mounted and connected to the first movable module 25. The second servo motor 27 is mounted on the second movable module 26, and the output end of the second servo motor 27 is connected to the milling cutter 38.

[0117] When it is necessary to mill the welds on the busbar, the second moving module 26 is started, driving the second servo motor 27 and the milling cutter 38 to move to the top of the weld to be milled. The first moving module 25 then drives the milling cutter 38 to descend, and the second servo motor 27 is started at the same time. The milling cutter 38 gradually approaches the weld and mills it. Similarly, the milling cutter 38 mills the welds on the busbar in turn. The welds on the busbar of the battery module corresponding to the square battery cell are located on the same side and are distributed in two rows. The milling path of the milling cutter 38 is milled in a "J" shape. The welds on the busbar of the battery module corresponding to the cylindrical battery are located on opposite sides. After the milling cutter 38 completes milling of the welds on one side, the battery module is flipped over by the first robotic arm 31 or the transfer robot 02 to facilitate the milling cutter 38 to mill the welds on the other side. By adopting the milling method in which the first movable module 25 and the second movable module 26 cooperate with each other, it is possible to achieve accurate milling of the welding points on the busbar, thereby improving the efficiency of the welding point milling.

[0118] In this embodiment of the present invention, the specific structure of the first movable module 25 can be various forms known to people in this field, such as driving the threaded sleeve to move by rotating the screw, driving the conveyor belt to move by rotating the wheel hub, and cooperating with the cylinder and the slide rail.

[0119] In this embodiment of the present invention, the specific structure of the second movable module 26 can be various forms known to people in this field, such as driving the threaded sleeve to move by rotating the screw, driving the conveyor belt to move by rotating the hub, and cooperating with the cylinder and the slide rail.

[0120] In this embodiment of the invention, Figure 3 and Figure 4 As shown, the tool changing assembly 29 may include a tool changing bracket 33, a tool changing plate 34, a tool changing cylinder, a main shaft, a plurality of milling tool holders 35 and a plurality of spare milling tools 36. Specifically, a clamping claw structure is provided inside the main shaft.

[0121] The tool change bracket 33 is mounted on the side of the inverted U-shaped support plate 24 away from the milling box 32. The tool change plate 34 is mounted above the tool change bracket 33. Multiple milling cutter fixtures 35 are mounted on the side of the tool change plate 34 near the milling cutter 38. Multiple spare milling cutters 36 are mounted within corresponding milling cutter fixtures 35. A tool change cylinder is mounted on top of the tool change bracket 33. The output of the tool change cylinder is connected to the tool change plate 34, driving the spare milling cutters 36 to move along the bottom of the second servo motor 27. The output of the second servo motor 27 is connected to the spindle.

[0122] When the tool needs to be changed, the tool-changing cylinder drives multiple spare milling cutters 36 to move to the bottom of the main shaft. The first movable module 25 and the second movable module 26 move the main shaft to the top of the required spare milling cutter 36 according to the size of the weld spot, and gradually approach the spare milling cutter 36. The clamping structure inside the main shaft installs and fixes the spare milling cutter 36 to achieve the purpose of tool change. In this embodiment of the present invention, the clamping structure can be in various forms known to those skilled in the art, including but not limited to the tool-changing structure of a pneumatic machine tool. The tool-changing method using this tool-changing assembly can meet the milling of weld spots of battery modules of different models, and the tool-changing efficiency is high, without affecting the milling efficiency of the weld spots on the battery modules.

[0123] In this embodiment of the present invention, the milling cutter 38 may include a tool holder and a milling cutter. Specifically, the tool holder is used to connect with the spindle.

[0124] In this embodiment of the invention, Figure 3 and Figure 4 As shown, the first waste chip recovery assembly 23 may include a recovery box, a recovery motor, and a screw shaft.

[0125] The recycling motor is arranged inside the recycling box, the output end of the recycling motor is connected to one end of the screw shaft, the top of the recycling box is open, and one end of the recycling box passes through the protective fence and extends to the outside of the protective fence.

[0126] When waste chips generated during battery module milling enter the recycling bin, the recycling motor rotates, driving the spiral shaft, which then spirals the waste chips to the outside of the protective fence for easy recycling by staff. This recycling method is more convenient and has high recycling efficiency.

[0127] In this embodiment of the invention, Figure 5 As shown, the manifold milling machine 04 may further include a lifting cylinder, a pressing head 39, a smoke alarm 40, a first workpiece in-position detection device 41, and a first visual inspection camera 42. Specifically, the pressing head 39 may include a connection opening.

[0128] A lifting cylinder is mounted on the side wall of the second servo motor 27. A ram 39 is positioned near the bottom end of the milling cutter 38, with the output end of the lifting cylinder connected to the ram 39. A smoke alarm 40 is also mounted on the side wall of the second servo motor 27. A first workpiece presence detection device 41 is also mounted on the side wall of the second servo motor 27. A first visual inspection camera 42 is also mounted on the side wall of the second servo motor 27. A connection opening is provided on the side wall of the ram 39 for connecting to a vacuum cleaner to collect debris generated during the milling process.

[0129] The first workpiece presence detection device 41 detects the presence of a battery module within the milling box 32 to prevent the transfer robot 02 from repeatedly gripping the battery module and reentering the milling box 32. The first visual inspection camera 42 detects the size and position of the welds on the busbar, facilitating the replacement of the corresponding milling cutter 38 with the tool changer 29. It also works with the milling assembly 28 to mill all welds on the busbar. The smoke alarm 40 provides real-time detection of battery spontaneous combustion during the milling process and issues a prompt alarm, allowing personnel to take appropriate action. During the milling process, the pressing head 39 first contacts the busbar with the milling cutter 38 and presses against it, further improving the milling accuracy of the milling cutter 38. Furthermore, the connection opening can be connected to a vacuum cleaner, allowing waste chips generated by the milling cutter 38 to be sucked away through the connection opening, preventing waste chips from splashing and disrupting the normal operation of the busbar milling machine 04.

[0130] In this embodiment of the present invention. Figure 6 、 Figure 7 and Figure 8 As shown, the battery guard plate cutting device 06 may include a cutting base 43, a frame plate 50, a cutting box 51, a cutting blade 59, a second guide assembly 52, a second stop assembly, a cutting assembly 49, and a second waste recycling assembly 53. Specifically, the cutting base 43 may include a second notch 54; the frame plate 50 may include a plurality of connecting posts 44; and the cutting box 51 may include two cutting openings.

Cutting openings are defined at both the top and bottom of the cutting box 51, and a cutting blade 59 is positioned above the cutting box 51. A second guide assembly 52 is positioned at the top of the cutting base 43 and connected to the second guide assembly 52. ​​The second guide assembly 52 is configured to drive the cutting box 51 along the cutting port of the cutting base 43 and below the cutting blade 59. A second limiting assembly is positioned at the top of the cutting box 51 to limit and secure the battery module within the cutting box 51. A cutting assembly 49 is positioned at the top of the frame plate 50 and connected to the cutting blade 59 to drive the cutting blade 59 toward the battery module at the top of the cutting box 51 and cut the protective plate of the battery module.

[0132] Before the guard plate of the battery module needs to be cut, the transfer robot 02 transfers the battery module milled at the milling port to the top of the cutting box 51 at the cutting port, and fixes it by the second limiting assembly. The second guide assembly 52 drives the cutting box 51 to move to the bottom of the cutting knife 59, and the cutting assembly 49 drives the cutting knife 59 to cut the guard plate of the battery module. The waste generated during the cutting process enters the interior of the second waste recovery assembly 53 along the two cutting openings on the cutting box 51, and is recovered by the second waste recovery assembly 53. The method of using the cutting assembly 49 to drive the cutting knife 59 to cut the guard plate is simple and fast, and has high cutting accuracy, which can protect the battery module from damage.

[0133] In this embodiment of the present invention, the number of the cutting blades 59 can be various forms known to those skilled in the art, such as 1, 2, etc. However, in a preferred embodiment of the present invention, considering the efficiency of the cutting blade 59 and the integrity of the battery module, the specific number of the cutting blades 59 can be as follows: Figure 7 Specifically, in the figure, the specific number of the cutting blades 59 is 2.

[0134] In this embodiment of the present invention, the specific structure of the second guide assembly 52 can be various forms known to those skilled in the art, including but not limited to a cylinder, a ball screw, etc.

[0136] A first limiting cylinder 56 is mounted on the top of the cutting box 51, located on one of the short sides of the battery module. Its output is connected to a first limiting plate 57. A second limiting plate 58 is mounted on the top of the cutting box 51, located on the other short side of the battery module. Two second limiting cylinders 60 are mounted on the top of the cutting box 51, one on each of the long sides of the battery module. These two second limiting cylinders 60 are positioned opposite each other, with their outputs connected to corresponding third limiting plates 61.

[0137] To secure the battery module atop the cutting box 51, the first limiting cylinder 56 activates and drives the first limiting plate 57 to push the battery module until the first limiting plate 57 and the second limiting plate 58 cooperate to secure the two short sides of the battery module. Simultaneously, the two second limiting cylinders 60 activate and drive the corresponding third limiting plates 61 to secure the two long sides of the battery module. This coordinated securing of the first limiting plate 57, the second limiting plate 58, and the two third limiting plates 61 ensures reliable securing of the battery module, facilitating precise cutting of the protective plate by the cutting blade 59.

[0138] In this embodiment of the invention, Figure 6 、 Figure 7 and Figure 8 As shown, the cutting assembly 49 may include two third moving modules 45 , two fourth moving modules 46 , two cutting cylinders 47 and two third servo motors 48 .

Two cutting cylinders 47 are respectively arranged on opposite sides of the two fourth movable modules 46, two third servo motors 48 are respectively arranged at the bottom ends of the two cutting cylinders 47, and two cutting blades 59 are respectively arranged at the output ends of the two third servo motors 48.

[0140] When the battery module shield needs to be cut, the third movable module 45 is activated and drives the two fourth movable modules 46 to move the corresponding cutting knives 59 closer together and above the battery module. The two fourth movable modules 46 are activated to drive the corresponding cutting knives 59 to move directly above the corresponding cutting position. The two cutting cylinders 47 drive the corresponding cutting knives 59 downward, and the two third servo motors 48 are activated to achieve cutting of two diagonal corners of the battery module shield. Similarly, the two cutting knives 59 are driven to cut the other two diagonal corners of the battery module shield to achieve cutting of the battery module shield.

[0141] In this embodiment of the present invention, the specific structure of the second waste chip recovery assembly 53 can be various forms known to those skilled in the art, including but not limited to a spiral recovery machine, a recovery inclined plate, etc.

[0142] In this embodiment of the present invention, the battery shield cutting device 06 may further include a first light strip sensor 55. Specifically, the first photoelectric sensor 55 is disposed on top of the cutting base 43 and is used to monitor and identify the position of the cutting box 51 to further achieve precise cutting of the battery module shield.

[0143] In this embodiment of the invention, Figure 9 、 Figure 10 and Figure 11 As shown, the battery shield removal device 07 may include a removal base 62, a removal support base 77, two first removal components 63, two second removal components 72, a fourth limiting component 69, a plurality of removal openings 79, and a shield recovery component 70.

[0144] The dismantling base 62 is located on the side of the cutting base 43, and the dismantling support seat 77 is located on the top of the dismantling base 62 for placing the battery module after the protective plate is cut. The two first dismantling assemblies 63 are located on the two opposite short sides of the battery module at the top of the dismantling base 62 and are arranged opposite each other. The top of the dismantling base 74 and the top of the dismantling support seat 77 are located on the same horizontal plane. The dismantling rod 75 is movable through the dismantling base 74. The dismantling cylinder 73 is located below the dismantling base 74 and is connected to the bottom of the dismantling base 74. The output end of the dismantling cylinder 73 is connected to the bottom end of the dismantling rod 75. The third limiting assembly 76 is located on the top of the dismantling base 74 and is used to fix the protective plates on the two short sides of the battery module and assist the dismantling rod 75 in removing the protective plates on the two short sides of the battery module. The two second dismantling assemblies 72 are located on the two opposite long sides of the battery module at the top of the dismantling base 62 and are arranged opposite each other. They are used to fix the protective plates on the two long sides of the battery module and cooperate with the two first dismantling assemblies 63 to remove the protective plates on the two long sides of the battery module. A fourth stopper assembly 69 is provided on top of the dismantling base 62 to secure the top of the battery module. Multiple dismantling openings 79 are defined on the dismantling base 62 and distributed around the dismantling support 77. A guard plate recovery assembly 70 is provided below the dismantling base 62 to cooperate with the multiple dismantling openings 79 to recover the guard plates removed from the battery module.

[0145] When the guard plate of the battery module needs to be removed, the transfer robot 02 transfers the battery module after the guard plate is cut to the top of the removal support seat 77. The fourth limiting assembly 69 limits and fixes the top of the battery module, while driving the two second removal assemblies 72 to limit and fix the two long sides of the battery module. Then, the two removal base plates 74 are driven to gradually approach the two short sides of the battery module until the two removal base plates 74 abut against the removal support seat 77. The two third limiting assemblies 76 are driven to limit and fix the two short sides. The removal cylinder 73 drives the removal rod 75 to enter the interior of the short side guard plate, drives the two removal base plates 74 to reset, and pulls the two short side guard plates through the removal rod 75 to achieve the removal of the two short side guard plates. The two second removal assemblies 72 are driven to reset, and the two long side guard plates fall down and fall out along multiple removal openings 79. The guard plates are then uniformly recovered by the guard plate recovery assembly 70, thereby achieving the removal of the battery module guard plate. This dismantling method can achieve stable removal of the guard plate without causing damage to the battery cell module inside the battery module, and the dismantling efficiency is high.

[0146] In this embodiment of the invention, Figure 9 and Figure 10 As shown, the first disassembly assembly 63 may further include two push cylinders. Specifically, the two push cylinders are respectively arranged at one end of the two disassembly base plates 74 away from each other and connected to the corresponding disassembly base plates 74 to drive the corresponding disassembly base plates 74 to approach or move away from the disassembly support seat 77.

Specifically, the second ball screw 71 is disposed on the side of one of the second disassembly assemblies 72, and the nut of the second ball screw 71 is connected to the fifth limit cylinder of one of the second disassembly assemblies 72. When the transfer robot 02 needs to transfer the battery module after the protective plate is cut to the top of the disassembly support, the second ball screw 71 drives one of the second disassembly assemblies 72 to move out of the way to make way for the transfer of the battery module.

[0150] In this embodiment of the invention, Figure 9 As shown, the fourth limiting assembly 69 may include a second inverted U-shaped support plate 64 , a first top pressure plate 65 , a first pressing cylinder 66 , a receiving plate 67 and a receiving cylinder 68 .

The first pressing cylinder 66 is located at the end of the storage plate 67 near the battery module, and the output end of the first pressing cylinder 66 is connected to the first top pressing plate 65.

[0152] When it is necessary to press the top of the battery module on the removal support seat 77, the storage cylinder 67 drives the storage plate 67 and the first top pressure plate 65 to move to the top of the battery module, and then the first pressing cylinder 66 drives the first top pressure plate 65 to gradually approach the top of the battery module, thereby achieving the pressing limit on the top of the battery module.

[0153] In this embodiment of the present invention, the guard plate recovery assembly 70 can be in various forms known to those skilled in the art, including but not limited to a conveyor belt, a recovery ramp, etc.

[0154] In this embodiment of the present invention, the battery guard plate removal device 07 may further include a positioning plate 78 , a plurality of partitions 80 and a plurality of inclined plates 81 .

[0155] A positioning plate 78 is positioned below the first vacuum cup and connected to the output of the fourth limiting cylinder. The positioning plate 78 engages with the bottom groove of the battery module to precisely position and define the battery module. Multiple partitions 80 are positioned between the multiple removal openings 79 to define the drop zone for the guard plate, preventing it from remaining on top of the removal base 62 and interfering with the removal of guard plates from other battery modules. Multiple inclined plates 81 are positioned on the sidewalls of the removal support 77 to assist in the recovery of dropped guard plates.

[0156] In this embodiment of the invention, Figures 12 to 16As shown, the battery cell slitting and detection device 11 may include a slitting base 82, a slitting knife 100, a slitting box 83, a third guide assembly 88, a fifth limit assembly 86, a slitting assembly 90, a first slide rail 95, an assist seat 104, a first ball screw 93, a first servo motor 94, an L-shaped plate 103, and a first pneumatic clamp 102. Specifically, the slitting box 83 may include a slitting opening 87.

[0157] The slitting knife 100 is arranged above the slitting base 82, and the slitting box 83 is arranged on the top of the slitting base 82. A slitting opening 87 is opened on the top of the slitting box 83, and one end of the slitting box 83 extends to the tip side of the slitting knife 100. The third guide assembly 88 is arranged inside the slitting box 83, and is used to drive the battery cell module after the protective plate is removed from the slitting box 83 to move to one end of the slitting box 83. The fifth limiting assembly 86 is arranged near one end of the slitting box 83, and is used to limit the battery cells other than the first battery cell that is fixed to the end of the battery cell module close to the slitting knife 100. The slitting assembly 90 is arranged on the top of the slitting base 82 and is connected to the slitting knife 100. It is used to drive the slitting knife 100 to move and cooperate with the fifth limiting assembly 86 to slitting a single battery cell in the battery cell module. A first slide rail 95 is mounted at one end of the slitting box 83, and an assist base 104 is slidably connected to the first slide rail 95. A first ball screw 93 is mounted on top of the slitting base 82, and the nut of the first ball screw 93 is connected to the assist base 104. A first servo motor 94 is mounted at one end of the first ball screw 93 and connected to one end of the first ball screw 93. An L-shaped plate 103 is mounted on the assist base 104 on a side of the slitting box 83, with the inner bottom surface of the L-shaped plate 103 and the top surface of the slitting box 83 being flush with each other. A first pneumatic clamp 102 is mounted on the assist base 104 and is used to clamp and secure individual battery cells on the L-shaped plate 103.

[0158] Before the cells on the cell module need to be cut, the transfer robot 02 needs to transfer the cell module to the cutting bottom box 83 and move the cell module to the cutting position through the third guide assembly 88. When the cell module reaches the cutting position, the fifth limiting assembly 86 limits and fixes the cells other than the first cell at the end of the cell module near the cutting knife 100. When the cell module reaches the cutting position, the first cell of the cell module is inside the L-shaped plate 103, and the first pneumatic clamp 102 clamps and fixes the first cell. Then the cutting assembly 90 is driven to start, driving the cutting knife 100 to cut the first cell. After the first cell is cut, the first servo motor 94 is started and drives the first ball screw 93 to rotate, thereby driving the auxiliary seat 104 and the first cell to move to the position to be transferred and tested, so as to facilitate the subsequent testing of the first cell. Similarly, the third guide assembly 88 drives the remaining cell modules to move to the preset position to wait for cutting. This slitting method can achieve stable and accurate slitting of battery cell modules one by one.

[0159] In this embodiment of the present invention, the specific structure of the third guide assembly 88 can be various forms known to those skilled in the art, such as a cylinder, a ball screw, etc. However, in a preferred embodiment of the present invention, considering the precision of the movement of the battery module, the specific structure of the third guide assembly 88 can be a fourth servo motor, a third ball screw, and a push plate. Specifically, the output end of the fourth servo motor is connected to one end of the third ball screw, and the push plate movably extends through the slit opening 87, and one end of the push plate is connected to the nut of the third ball screw.

[0160] When the battery cell module needs to be driven to move, the fourth servo motor is started and drives the third ball screw to rotate, and the third ball screw drives the battery cell module to move through the push plate.

[0161] In this embodiment of the invention, Figure 12 As shown, the slitting assembly 90 may include a first electric cylinder 89 and a slitting support plate 99. Specifically, the slitting support plate 99 is disposed on the slitting base 82, and the first electric cylinder 89 is disposed on a side wall of the slitting support plate 99. The output end of the first electric cylinder 89 is connected to a slitting blade 100. Specifically, the first electric cylinder 89 drives the slitting blade 100 to move and slit the battery cells.

[0162] In this embodiment of the invention, Figure 12 As shown, the fifth limiting assembly 86 may include a third limiting cylinder 84, two fourth limiting plates 85, a second pressing cylinder 91 and a second top pressing plate 92. The fourth limiting plate 85 may include a second gasket.

A second top pressure plate 92 is arranged above the battery module, and a second pressing cylinder 91 is arranged on the side wall of the slitting support plate 99, with the output end of the second pressing cylinder 91 connected to the second top pressure plate 92. A second gasket is arranged on the inner wall of the fourth limiting plate 85 to protect the battery module.

[0164] When the cell module reaches the slitting position, the third limiting cylinder 84 activates and pushes the other fourth limiting plate 85 to move, so that the two fourth limiting plates 85 clamp the side walls of the cell module. At the same time, the second pressing cylinder 91 activates and drives the second top pressing plate 92 to press and clamp the top of the cell module, thereby achieving stable clamping of the cell module.

[0165] In this embodiment of the present invention, the cutting box 83 may further include a first gasket 98. Specifically, the first gasket 98 is disposed on the top of the cutting box 83 to protect the battery cell module.

[0166] In this embodiment of the present invention, the battery cell slitting detection device 11 may further include a second visual inspection camera and a second workpiece presence detection device. Specifically, the second visual inspection camera and the second workpiece presence detection device are both arranged on the side of the slitting box 83. The second visual inspection camera is used to identify the slitting gap position of the battery cell module, and the second workpiece presence detection device is used to detect and identify whether there is a battery cell module on the slitting box 83, thereby enabling accurate slitting of the battery cells.

Two second pneumatic grippers 97 are disposed at the ends of the second robotic arm 96.

[0169] When a single square battery cell needs to be inspected, the second robotic arm 96 clamps the single battery cell on the L-shaped plate 103 to the top of the inspection support seat 105 and clamps the battery cell through the sixth limit assembly 118. The visual inspection drive assembly drives the visual inspection device 112 to identify and locate the position of the detection contact on the battery cell, and the first detection probe drive assembly then drives the two first detection probes 111 to contact the detection contacts on the battery cell to achieve inspection of the single battery cell. The use of the visual inspection device 112 and the two first detection probes 111 to cooperate in performing performance inspection on the battery cell can achieve high-precision inspection of the battery cell, thereby ensuring the accuracy of the battery cell inspection.

The two position-limiting clamping plates 117 are respectively located on both sides above the detection support base 105, and the two third position-limiting cylinders 116 are respectively connected to the corresponding position-limiting clamping plates 117.

[0171] When a single battery cell is placed on the top of the detection support seat 105, the two third limiting cylinders 116 start to drive the corresponding limiting clamping plates 117 to clamp and fix the single battery cell for subsequent detection.

[0172] In this embodiment of the invention, Figures 12 to 15 As shown, the visual detection drive assembly may include a second drive cylinder 113 , a second support plate 114 , and a first drive cylinder 108 .

The output end of the first driving cylinder 108 is connected to the second support plate 114. The second driving cylinder 113 is disposed on a side of the second support plate 114 away from the first driving cylinder 108. The output end of the second driving cylinder 113 is connected to the visual inspection device 112.

[0174] When the detection contact position of the battery cell needs to be identified, the first driving cylinder 108 starts and drives the visual detection device 112 to move above the battery cell, and the second driving cylinder 113 then drives the visual detection device to reciprocate along the top of the battery cell to achieve precise positioning of the detection contact.

[0175] In this embodiment of the invention, Figures 12 to 15 As shown, the first detection probe driving assembly may include a second electric cylinder 107 , a first support plate 109 and a third electric cylinder 110 .

[0177] After identifying the battery cell's test contacts, the third electric cylinder 110 activates and drives another first test probe 111 to move, positioning the two first test probes 111 directly above the two test contacts on the battery cell. The second electric cylinder 107 then drives the two first test probes 111 downward, bringing them into contact with the corresponding test contacts, thereby testing the battery cell's performance. Furthermore, a fifth electric cylinder can be positioned at the bottom of the first support plate 109, with one of the first test probes 111 connected to the output of the fifth cylinder. These two cylinders work together to precisely adjust the positions of the two first test probes 111.
