Description

Technical Field

[0001] This application relates to the field of battery production technology, and in particular to a battery cell air bag packaging and cutting device, edge sealing equipment, and solid-state battery production line. Background Technology

[0002] In the current battery production process, after the steps of liquid injection, formation, and capacity testing, the edges of the cell's gas bag need to be sealed, and then the edges of the sealed gas bag are cut. In the current production process, after the cell's gas bag is sealed by a sealing device, a robotic arm holds the cell and transfers it to a cutting device for edge cutting. During this transfer process, the cell's position is prone to shifting, leading to cutting deviation during gas bag cutting. This can cause the cell's seal to fail, affecting the cell's production yield. Utility Model Content

[0003] To address one of the aforementioned technical problems, this application provides a packaging and cutting device for a battery cell air bag, comprising a flipping assembly, a first support platform and a second support platform symmetrically arranged on both sides of the flipping assembly. The flipping assembly is used to transfer the battery cell between the first support platform and the second support platform. A packaging assembly is disposed on the side of the first support platform away from the flipping assembly, and the packaging assembly is used to package the edge of the air bag of the battery cell. A cutting assembly is disposed on the side of the second support platform away from the flipping assembly, and the cutting assembly is used to cut the edge of the air bag of the battery cell to separate the battery cell from the air bag. The flipping assembly is used to transfer the battery cell between the first support platform and the second support platform. After the battery cell is placed on the first support platform, the packaging assembly packages the edge of the air bag of the battery cell. Then, the flipping assembly clamps the battery cell and transfers it from the first support platform to the second support platform, and finally, the cutting assembly cuts the edge of the air bag of the battery cell. Since the first and second carrier platforms are symmetrically arranged on both sides of the flipping assembly, it can be ensured that the battery cell will not shift during the transfer process, thereby ensuring that there will be no shift during the cutting of the air bag, improving the accuracy of cutting the air bag, and thus improving the production yield of the battery cell.

[0004] Preferably, the assembly further includes limiting components mounted above the first and second support platforms, with the two limiting components symmetrically arranged about the flipping component. Thus, after the battery cell is placed on the first and second support platforms, the limiting components limit the battery cell within the limiting cavity, ensuring that the cell's position does not shift, thereby improving packaging and cutting quality.

[0005] Preferably, the limiting component includes a limiting frame, on which a first driver and a second driver are disposed. The driving end of the first driver is connected to a first limiting block, and the driving end of the second driver is connected to a second limiting block. The first and second drivers are cylinders. After the battery cell is placed on the first and second support platforms, the first and second drivers respectively drive the first and second limiting blocks to limit the battery cell, ensuring that no positional displacement occurs during the packaging and cutting process.

[0006] Preferably, a third driver is provided on both the first and second support platforms, and a third limiting block is provided at the driving end of the third driver. The third driver then drives the third limiting block to move closer to or further away from the battery cell within the limiting cavity, further limiting the battery cell and improving the stability of the battery cell's position during processing.

[0007] Preferably, the assembly further includes symmetrically arranged adjustment components on both sides of the flipping assembly. Each adjustment component includes a horizontal displacement module and a lifting module disposed on the horizontal displacement module. The first or second support platform is disposed at the drive end of the lifting module. The lifting module then drives the first and second support platforms to move up and down, thereby adjusting their height positions to meet the packaging and cutting requirements of different sized battery cells, thus improving compatibility.

[0008] Preferably, the flipping assembly includes a fixing frame and a flipping driver mounted on the fixing frame. A clamping driver is provided at the driving end of the flipping driver, and the driving end of the clamping driver is provided with a clamping plate for holding the battery cell. The battery cell is then clamped by the clamping driver, and the flipping driver drives the clamping driver to flip, transferring the battery cell from the first support platform to the second support platform. Since the first and second support platforms are symmetrically arranged, it can be ensured that the battery cell will not shift during the transfer process, thereby ensuring that no shift occurs during the cutting of the air bag.

[0009] Preferably, the cutting assembly includes a cutting frame, a lower cutting module disposed on the cutting frame, and a first lifting module, with an upper cutting module slidably disposed on the cutting frame and connected to the drive end of the first lifting module. The upper cutting module is driven by the first lifting module to move towards the lower cutting module, thereby cutting the edge of the battery cell air bag. Alternatively, an air bag recovery chamber may be provided within the cutting frame for recovering cutting waste.

[0010] Preferably, the encapsulation assembly includes an encapsulation frame, an upper encapsulation module and a lower encapsulation module slidably disposed on the encapsulation frame, and a second lifting module and a third lifting module provided on the encapsulation frame. The second lifting module is connected to the upper encapsulation module, and the third lifting module is connected to the lower encapsulation module. The second lifting module drives the upper encapsulation module to move towards the lower encapsulation module, and the third lifting module drives the lower encapsulation module to move towards the upper encapsulation module, thereby achieving the encapsulation of the edge of the battery cell air bag.

[0011] Preferably, a sealing device includes the aforementioned battery cell air bag sealing and cutting apparatus. It is used to perform air bag sealing and cutting processes on battery cells after liquid injection, formation, and capacity testing. This avoids displacement of the battery cell position during transfer between the sealing and cutting components, improving the battery cell processing quality.

[0012] Preferably, a solid-state battery production line includes the aforementioned cell gas bag packaging and cutting device. This device is used to perform packaging and cutting processes on the solid-state battery cells, thereby improving the battery production yield.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: This application symmetrically arranges a first support platform and a second support platform on both sides of the flipping component. A sealing component is arranged on the side of the first support platform away from the flipping component, and a cutting component is arranged on the side of the second support platform away from the flipping component. The flipping component is used to transfer the battery cell between the first and second support platforms. After the battery cell is placed on the first support platform, the sealing component seals the edge of the air bag of the battery cell. Then, the flipping component clamps the battery cell and transfers it from the first support platform to the second support platform. Finally, the cutting component cuts the edge of the air bag of the battery cell. Because the first and second support platforms are symmetrically arranged on both sides of the flipping component, it can be ensured that the battery cell will not shift during the transfer process, thereby ensuring that there is no shift during the cutting of the air bag, improving the accuracy of cutting the air bag, and thus improving the production yield of the battery cell.

Detailed Implementation

[0018] The following drawings disclose several embodiments of this application. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this application. That is, in some embodiments of this application, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0019] It should be noted that all directional indications in the embodiments of this application, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0020] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit this application. They are merely used to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0021] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings: To address the aforementioned technical problems, this embodiment provides a packaging and cutting device for battery cell gas bags, such as... Figure 1-2 As shown, the device includes a flipping assembly 10, with a first support platform 20 and a second support platform 30 symmetrically arranged on both sides of the flipping assembly 10. A sealing assembly 50 is located on the side of the first support platform 20 away from the flipping assembly 10, and a cutting assembly 40 is located on the side of the second support platform 30 away from the flipping assembly 10. The flipping assembly 10 is used to transfer the battery cell between the first support platform 20 and the second support platform 30. After the battery cell is placed on the first support platform 20, the sealing assembly 50 seals the edge of the air bag of the battery cell. Then, the flipping assembly 10 clamps the battery cell and transfers it from the first support platform 20 to the second support platform 30. Finally, the cutting assembly 40 cuts the edge of the air bag of the battery cell to separate the battery cell from the air bag. Because the first support platform 20 and the second support platform 30 are symmetrically arranged on both sides of the flipping assembly 10, it can be ensured that the battery cell will not shift during the transfer process, thereby ensuring that there is no shift during the cutting of the air bag, improving the accuracy of the cutting of the air bag, and thus improving the production yield of the battery cell.

[0022] Specifically, the first support platform 20 and the second support platform 30 form a limiting cavity 23 for accommodating the battery cell. Several suction cups 24 are provided on the limiting cavity 23. It also includes a limiting component 60 mounted above the first support platform 20 and the second support platform 30. The two limiting components 60 are symmetrically arranged about the flipping component 10. After the battery cell is placed on the first support platform 20 and the second support platform 30, the limiting component 60 limits the battery cell in the limiting cavity 23. Then, the suction cups 24 are used to adsorb and fix the battery cell. This ensures that the position of the battery cell will not shift when the packaging component 50 packages the edge of the air bag of the battery cell and when the cutting component 40 cuts the edge of the air bag of the battery cell, thereby improving the packaging and cutting quality.

[0023] Furthermore, the limiting component 60 includes a limiting frame 61, on which a first driver 62 and a second driver 63 are disposed. The driving end of the first driver 62 is connected to a first limiting block 64, and the driving end of the second driver 63 is connected to a second limiting block 65. The driving directions of the first driver 62 and the second driver 63 are perpendicular. For example, the first driver 62 and the second driver 63 are cylinders. After the battery cell is placed on the first support platform 20 and the second support platform 30, the first driver 62 and the second driver 63 respectively drive the first limiting block 64 and the second limiting block 65 to limit the battery cell, ensuring that no positional displacement occurs during the packaging and cutting process.

[0024] Furthermore, a third driver 21 is respectively provided on the first support platform 20 and the second support platform 30. A third limiting block 22 is provided at the driving end of the third driver 21. The third driver 21 can be a cylinder. The third driver 21 drives the third limiting block 22 to move closer to or further away from the battery cell in the limiting cavity 23, thereby further limiting the battery cell and improving the stability of the battery cell position during the processing.

[0025] Furthermore, the system also includes symmetrically arranged adjustment components 70 on both sides of the flipping component 10. The adjustment components 70 include a horizontal displacement module 71 and a lifting module 72 disposed on the horizontal displacement module 71. A first support platform 20 and a second support platform 30 are respectively disposed at the drive ends of the two lifting modules 72. For example, the horizontal displacement module 71 adopts a drive structure combining a motor and a lead screw, and the lifting module 72 can be a cylinder. A movable frame 73 is provided at the drive end of the horizontal displacement module 71. The first support platform 20 and the second support platform 30 are slidably and vertically disposed on the movable frame 73 via guide posts and guide sleeves. The lifting modules 72 are disposed on the movable frame 73, thereby driving the first support platform 20 and the second support platform 30 to move vertically and vertically, thus adjusting the height position of the first support platform 20 and the second support platform 30. This allows for adjustment to adapt to the packaging and cutting requirements of battery cells of different sizes, improving compatibility.

[0026] In actual production, after the horizontal displacement module 71 drives the first support platform 20 to approach the packaging assembly 50 for edge packaging of the cell air bag, the horizontal displacement module 71 drives the first support platform 20 and the second support platform 30 to approach the flipping assembly 10. The flipping assembly 10 transfers the cell from the first support platform 20 to the second support platform 30, and a new cell to be processed is loaded onto the first support platform 20. At the same time, the horizontal displacement module 71 drives the second support platform 30 to approach the cutting assembly 40 for edge cutting of the cell air bag, and the horizontal displacement module 71 drives the first support platform 20 to approach the packaging assembly 50 to package the new cell to be processed. When the first support platform 20 and the second support platform 30 approach the packaging assembly 50 and the cutting assembly 40 respectively, the two sets of limiting components 60 limit the cells on the first support platform 20 and the second support platform 30 respectively.

[0027] To transfer the battery cell from the first support platform 20 to the second support platform 30, the flipping assembly 10 includes a fixing frame 11 and a flipping driver 12 mounted on the fixing frame 11. A clamping driver 13 is provided at the driving end of the flipping driver 12, and a clamping plate 14 for holding the battery cell is provided at the driving end of the clamping driver 13. For example, the flipping driver 12 is a motor, and the clamping driver 13 can be a cylinder. Two clamping plates 14 are provided on the clamping driver 13, which clamps the battery cell. The flipping driver 12 drives the clamping driver 13 to flip, thereby transferring the battery cell from the first support platform 20 to the second support platform 30. Since the first support platform 20 and the second support platform 30 are symmetrically arranged, it can be ensured that the battery cell will not shift during the transfer process, thereby ensuring that no shift occurs during the cutting of the air bag.

[0028] Furthermore, the cutting assembly 40 includes a cutting frame 41, a lower cutting module 42 disposed on the cutting frame 41, and a first lifting module 44. An upper cutting module 43 is slidably disposed on the cutting frame 41 and connected to the driving end of the first lifting module 44. The first lifting module 44 can be a cylinder, which drives the upper cutting module 43 to move toward the lower cutting module 42, thereby cutting the edge of the battery cell air bag. Alternatively, an air bag recovery chamber can be provided inside the cutting frame 41 for recovering cutting waste.

[0029] Furthermore, the packaging assembly 50 includes a packaging frame 51, an upper sealing module 52 and a lower sealing module 53 slidably disposed on the packaging frame 51, and a second lifting module 54 and a third lifting module 55 disposed on the packaging frame 51. The second lifting module 54 is connected to the upper sealing module 52, and the third lifting module 55 is connected to the lower sealing module 53. For example, both the second lifting module 54 and the third lifting module 55 can be driven by cylinders, thereby driving the upper sealing module 52 to move toward the lower sealing module 53 via the second lifting module 54, and driving the lower sealing module 53 to move toward the upper sealing module 52 via the third lifting module 55, thereby achieving the sealing of the edge of the battery cell air bag.

[0030] Furthermore, this embodiment provides an edge-sealing device, including the aforementioned battery cell air bag packaging and cutting device, used for air bag packaging and cutting of battery cells after liquid injection, formation, and capacity testing. During the transfer between the packaging assembly 50 and the cutting assembly 40, the position of the battery cell is prevented from shifting, thus improving the processing quality of the battery cell.

[0031] On the other hand, this embodiment provides a solid-state battery production line, including the above-mentioned cell air bag packaging and cutting device, for the production of solid-state batteries, which can improve the production yield of cells during the packaging and cutting processes.

[0032] In summary, in one or more embodiments of this application, the present application solution symmetrically arranges a first support platform and a second support platform on both sides of the flipping component. A sealing component is arranged on the side of the first support platform away from the flipping component, and a cutting component is arranged on the side of the second support platform away from the flipping component. The flipping component is used to transfer the battery cell between the first and second support platforms. After the battery cell is placed on the first support platform, the sealing component seals the edge of the air bag of the battery cell. Then, the flipping component clamps the battery cell and transfers it from the first support platform to the second support platform. Finally, the cutting component cuts the edge of the air bag of the battery cell. Because the first and second support platforms are symmetrically arranged on both sides of the flipping component, it can be ensured that the battery cell will not shift during the transfer process, thereby ensuring that there is no shift during the cutting of the air bag, improving the accuracy of cutting the air bag, and thus improving the production yield of the battery cell.

[0033] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
