Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] The following reference Figures 1 to 6 This application describes an automatic cell disassembly apparatus according to some embodiments.

[0029] See Figures 1 to 6 As shown, an embodiment of this application provides an automatic battery cell disassembly device, including: a support member 1, a placement platform 2, a lifting mechanism 3, and a collection box 4; wherein, the placement platform 2 and the lifting mechanism 3 are both installed on the support member 1, and the lifting mechanism 3 is disposed above the placement platform 2. Collection boxes 4 are disposed on opposite sides of the placement platform 2 along a first preset direction a. The placement platform 2 is used to place a stack of a first polarity electrode 9, a second polarity electrode 10, and a separator 11. The lifting mechanism 3 is used to fix one end of the separator 11 and drive it to rise, so that the first polarity electrode 9 and the second polarity electrode 10 on both sides of the separator 11 fall into the corresponding collection boxes 4 on both sides under the action of the separator 11.

[0030] As can be seen from the structure described above, the automatic cell disassembly device provided in this application can be used to disassemble the internal structure of the cell, and its working process is roughly as follows: First, the internal structure of the cell after removing the aluminum-plastic film, that is, the structure consisting of the first polarity plate 9, the second polarity plate 10 and the separator 11 stacked together, is then fixed at the starting end of the separator 11 on the lifting mechanism 3. Then, the lifting mechanism 3 is started, which drives the separator 11 to rise. During the process of the separator 11 rising, the first polarity plate 9 and the second polarity plate 10 stacked on both sides fall into the corresponding collection box 4 in the direction of the two sides respectively, thereby completely disassembling the internal structure of the cell automatically.

[0031] It is evident that the automatic cell disassembly device provided in this application can automatically disassemble the internal structure of the cell, greatly improving production efficiency. Moreover, it requires no manual operation, making it safer, more reliable, and free from safety hazards.

[0032] It should be noted that the internal structure of existing battery cells is roughly as follows: Figure 6 As shown, the diaphragm 11 is a single membrane with the same polarity on each side of the electrode. Therefore, when the diaphragm 11 is pulled up, the electrodes with the same polarity on the same side will fall into the same box.

[0033] Furthermore, preferably, the first preset direction a is the width direction of the support member 1 and the placement platform 2. Of course, it is not limited to this and can be other directions, such as the length direction of the support member 1 and the placement platform 2.

[0034] In this embodiment, preferably, as follows: Figure 1 , Figure 2 and Figure 5 As shown, the lifting mechanism 3 includes a lifting drive device 31, a rotating roller 32, and a fixing component 33; wherein, the fixed end of the lifting drive device 31 is fixed to the support member 1, and the driving end of the lifting drive device 31 is connected to the rotating roller 32. The fixing component 33 includes a pull rope 331 and a fixing clamp 332. One end of the pull rope 331 is fixed to the rotating roller 32, and the other end of the pull rope 331 is connected to the fixing clamp 332. The fixing clamp 332 is used to fix one end of the diaphragm 11. The lifting drive device 31 can drive the rotating roller 32 to rotate to wind up the pull rope 331, and cause the pull rope 331 to drive the fixing clamp 332 to rise during the winding process, so as to pull the diaphragm 11 upward. As can be seen from the structure described above, the lifting drive device 31 drives the rotating roller 32 to rotate, thereby winding up the pull rope 331. During the winding process, the fixing clamp 332 is lifted, which in turn lifts the diaphragm 11. As a result, during the lifting process, the first polarity plate 9 and the second polarity plate 10 on both sides are scattered into the corresponding collection box 4. The operation is simple, convenient, time-saving and labor-saving.

[0035] Furthermore, preferably, the lifting drive device 31 is a motor. Of course, it is not limited to this and can be selected according to actual needs. In this embodiment, preferably, as follows: Figure 5 As shown, both ends of the rotating roller 32 are rotatably connected to the support member 1. The support member 1 serves to stabilize the rotating roller 32, making it more stable during rotation. Of course, this is not the only possibility; the rotating roller 32 and the support member 1 may also have no connection whatsoever.

[0036] Furthermore, preferably, each end of the rotating roller 32 is rotatably connected to the support member 1 via a first bearing 34, thereby reducing friction during rotation. In this embodiment, preferably, as follows: Figure 5 As shown, there are two fixed components 33, which are arranged sequentially at intervals along the length of the rotating roller 32. As can be seen from the structure described above, using two fixing components 33 to stably clamp and lift the diaphragm 11 can effectively prevent the diaphragm 11 from falling off. Of course, it is not limited to this; only one fixing component 33 can be used, depending on the actual needs. In this embodiment, preferably, as follows: Figure 1 and Figure 4 As shown, the automatic cell disassembly device also includes a correction mechanism 5, and each collection box 4 is provided with a correction mechanism 5 on its side along the first preset direction a. The correction mechanism 5 is used to push the first polarity plate 9 or the second polarity plate 10 that has fallen into the collection box 4 so that the first polarity plate 9 or the second polarity plate 10 is corrected. As can be seen from the structure described above, the straightening mechanism 5 pushes the side of the first polarity plate 9 or the second polarity plate 10, thereby straightening the first polarity plate 9 or the second polarity plate 10 that is tilted in the horizontal plane, thus eliminating the need for subsequent manual adjustment and greatly improving production efficiency.

[0037] In this embodiment, preferably, as follows: Figure 4 As shown, the straightening mechanism 5 includes a mounting base 51 and a straightening component 52; wherein, the straightening component 52 includes a mounting base 51, a shaping drive device 521 and a straightening push plate 522, and the straightening push plate 522 is disposed in the collection box 4; The fixed end of the shaping drive device 521 is fixed to the mounting base 51. The drive end of the shaping drive device 521 passes through the side wall of the collection box 4 and is connected to the straightening push plate 522. The shaping drive device 521 can drive the straightening push plate 522 to push the first polarity plate 9 or the second polarity plate 10 in the collection box 4 to straighten. It can be seen that the side wall of the collection box 4 is provided with a clearance through hole to avoid the drive end of the shaping drive device 521. The drive end of the drive device can move freely along the clearance through hole. As can be seen from the structure described above, the shaping drive device 521 drives the straightening push plate 522 toward the side of the first polarity electrode 9 or the second polarity electrode 10 to straighten it.

[0038] Furthermore, preferably, the shaping drive device 521 is a cylinder. In this embodiment, preferably, as follows: Figure 4 As shown, the two alignment mechanisms 5 share a single mounting base 51, which saves parts and space, resulting in a higher degree of integration. Of course, this is not the only option; each of the two alignment mechanisms 5 can also be equipped with its own mounting base 51, depending on the specific needs. In this embodiment, preferably, as follows: Figure 1 As shown, the straightening push plate 522 is arranged vertically, the storage cavity of the collection box 4 is square, and the straightening push plate 522 is arranged parallel to the opposite side wall of the storage cavity. This structure is adapted to the square electrode plate, satisfying the storage and straightening operations. Of course, it is not limited to this. The straightening push plate 522 may not be parallel to the side wall of the collection box 4. In addition, the shape of the storage cavity of the collection box 4 is not limited to square. Furthermore, the direction of the straightening push plate 522 can also be designed according to actual needs.

[0039] In this embodiment, preferably, as follows: Figures 1 to 3 As shown, the automatic cell disassembly device also includes a conveying mechanism 6, and each collection box 4 is equipped with a conveying mechanism 6. The conveying mechanism 6 is used to receive the scattered first polarity electrode 9 or second polarity electrode 10, and to transport the first polarity electrode 9 or second polarity electrode 10 to the target location along the second preset direction b. As can be seen from the structure described above, the conveying mechanism 6 transports the stacked first polarity electrode 9 or second polarity electrode 10 to the target location without manual handling, saving time and effort. Of course, the aforementioned conveying mechanism 6 can also be omitted, and manual handling can be used instead, depending on the actual needs. Furthermore, preferably, the second preset direction is perpendicular to the first preset direction a to meet the usage requirements. Of course, it is not limited to this and can be selected according to actual needs.

[0040] Furthermore, preferably, the second orientation is the length direction of the collection box 4. Of course, it is not limited to this and can be other orientations, such as the width direction of the collection box 4.

[0041] In this embodiment, preferably, as follows: Figure 2 and Figure 3 As shown, the conveying mechanism 6 includes a conveying drive device 61, a lead screw 63, a lead screw nut 64, and a conveying plate 65. The lead screw nut 64 is threadedly connected to the lead screw 63, the conveying plate 65 is fixedly connected to the lead screw nut 64, and the conveying plate 65 is slidably connected to the inner wall of the collection box 4. The fixed end of the conveying drive device 61 is fixed to the support member 1, the driving end of the conveying drive device 61 is connected to the lead screw 63, and the lead screw 63 is rotatably connected to the wall of the collection box 4. The conveying drive device 61 can drive the lead screw 63 to rotate, thereby driving the lead screw nut 64 to move the conveying plate 65. Furthermore, preferably, the two conveying mechanisms 6 share a single conveying drive device 61, and each lead screw 63 is connected to the drive end of the conveying drive device 61 via a pulley transmission assembly 62. As can be seen from the structure described above, the transmission drive device 61 drives two lead screws 63 to rotate simultaneously through the pulley transmission assembly 62, thereby driving two lead screw nuts 64 to move the transmission plate 65 and the first polarity plate 9 and the second polarity plate 10 on it to the target location.

[0042] It should be noted that the two transmission mechanisms 6 may not share a single transmission drive device 61, but may each be equipped with a separate transmission drive device 61. In this case, there is no need to set up a pulley transmission assembly 62. The specific choice depends on the actual needs.

[0043] Furthermore, preferably, the transmission drive device 61 is a motor. Of course, it is not limited to this and can be selected according to actual needs.

[0044] Furthermore, preferably, one of the conveying plate 65 and the collection box 4 is provided with a groove 43, and the other is provided with a slider, and the slider is slidably engaged with the groove 43.

[0045] In this embodiment, preferably, as follows: Figure 2 As shown, the automatic cell disassembly device also includes a baffle 7, which is installed on the support member 1 and along the second preset direction b. The baffle 7 is located on the back of the placement platform 2 to prevent the first polarity electrode 9 or the second polarity electrode 10 from falling to the ground from the back of the placement platform 2. In this embodiment, preferably, as follows: Figure 2As shown, the automatic cell disassembly device also includes a photoelectric information sensor 12. Each collection box 4 is equipped with a photoelectric information sensor 12, and the photoelectric information sensor 12 is fixed to the support member 1 or the collection box 4 to detect the overall thickness of the first polarity electrode 9 or the second polarity electrode 10 inside the collection box 4.

[0046] As can be seen from the structure described above, the photoelectric information sensor 12 monitors the overall thickness of the stack of the first polar electrode 9 or the second polar electrode 10 in the collection box 4 in real time. When the set thickness is reached, the photoelectric information sensor 12 immediately sends a signal to the control system. After receiving the signal, the control system quickly starts the transmission drive device 61. The transmission drive device 61 drives the two lead screws 63 to rotate simultaneously through the pulley transmission assembly 62, thereby driving the two lead screw nuts 64 to drive the transmission plate 65 to move the first polar electrode 9 and the second polar electrode 10 on it to the target location.

[0047] In this embodiment, preferably, as follows: Figure 1 As shown, the top of the collection box 4 has an opening, which allows the scattered first polarity plate 9 or second polarity plate 10 to fall into the corresponding collection box 4.

[0048] In this embodiment, preferably, as follows: Figure 1 As shown, the collection box 4 is connected to the support member 1, which serves to reinforce the collection box 4 and prevent it from moving. It should be noted that the collection box 4 and the support member 1 can also be independent of each other, depending on the actual needs.

[0049] Furthermore, preferably, the collection box 4 and the support member 1 can be detachably connected by bolts, clips or welding. In this embodiment, preferably, as follows: Figure 3 As shown, the bottom of the collection box 4 is hollow, which serves to avoid the screw rod 63 and other structures, and facilitates the installation and disassembly of the screw rod 63 and other structures, especially for later maintenance. Of course, it is not limited to this; the bottom of the collection box 4 can also be closed, depending on the actual needs.

[0050] In this embodiment, preferably, as follows: Figure 1 As shown, the support component 1 includes four columns 101 and a connecting base plate 102; wherein, the four columns 101 are arranged in a square, and the bottoms of the four columns 101 are connected by the connecting base plate 102; the placement platform 2 is fixed in the cubic space enclosed by the four columns 101, and the placement platform 2 is located above the connecting base plate 102 and spaced apart from the connecting base plate 102; the collection box 4 is disposed on the side of the columns 101 and the placement platform 2; the lifting mechanism 3 is fixed to the columns 101 by the support plate 8.

[0051] As can be seen from the structure described above, the four pillars 101 and the connecting base plate 102 are connected to form a basic frame, which can support the placement platform. Moreover, the sides of the cubic space formed by the four pillars 101 are unobstructed, so it will not affect the first polarity plate 9 or the second polarity plate 10 from falling into the corresponding collection box 4.

[0052] It should be noted that the structure of the supporting component 1 is not limited to the above, and other types of frame structures can also be used, depending on the actual needs.

[0053] Furthermore, preferably, the connecting base plate 102 can be connected to the first frame and the second frame by welding or bolts, etc.

[0054] Furthermore, preferably, the placement platform 2 can be connected to the first frame and the second frame by welding or bolts, etc.

[0055] In this embodiment, preferably, as follows: Figure 2 As shown, the collection box 4 includes three low side plates 41 and three high side plates 42; wherein, the three high side plates 42 are arranged close to the placement platform 2, and the three low side plates 41 are arranged away from the placement platform 2; the three high side plates 42 form a U-shaped structure with a front opening, and the three low side plates 41 form a U-shaped structure with a rear opening, and the openings of the two U-shaped structures are arranged opposite each other, and the two U-shaped structures are connected. Based on the structure described above, a high side plate 42 should be used near the placement platform 2 to prevent the first polarity electrode 9 or the second polarity electrode 10 from falling off. A low side plate 41 should be used away from the placement platform 2 to facilitate the later removal of the stacked first polarity electrode 9 or the second polarity electrode 10 from the collection box 4, thus improving the convenience of operation.

[0056] Of course, the structure of collection box 4 is not limited to this.

[0057] In summary, the detailed working process of the automatic cell disassembly device provided in this application is as follows: First, the internal structure of the battery cell after removing the aluminum-plastic film is determined. This structure consists of a first polarity electrode 9, a second polarity electrode 10, and a separator 11 stacked together. Then, the starting end of the separator 11 is held by a fixing clamp 332. Next, the lifting drive device 31 is activated, which drives the rotating roller 32 to rotate, thereby winding up the pull rope 331. During the winding process, the fixing clamp 332 is lifted, which in turn lifts the separator 11. As the separator 11 is lifted, the first polarity electrode 9 and the second polarity electrode 10 on both sides fall into the corresponding collection box 4, thus realizing the disassembly of the battery cell. During the disassembly process, the shaping drive device 521 will be activated intermittently, thereby driving the straightening push plate 522 toward the side of the first polarity electrode 9 or the second polarity electrode 10, so that the first polarity electrode 9 or the second polarity electrode 10 is straightened. Meanwhile, the photoelectric information sensor 12 monitors the overall thickness of the stack of the first polar electrode 9 or the second polar electrode 10 in the collection box 4 in real time. When the set thickness is reached, the photoelectric information sensor 12 immediately sends a signal to the control system. After receiving the signal, the control system quickly starts the transmission drive device 61. The transmission drive device 61 drives the two lead screws 63 to rotate simultaneously through the pulley transmission assembly 62, thereby driving the two lead screw nuts 64 to drive the transmission plate 65 to move the first polar electrode 9 and the second polar electrode 10 on it to the target location.

[0058] As can be seen, this application provides an automatic battery cell disassembly device that can automatically disassemble the internal structure of the battery cell, greatly improving production efficiency. Moreover, it requires no manual operation, making it safer, more reliable, and free from safety hazards.

[0059] It should be noted that the above work process is only an example and can be adjusted according to actual needs.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
