Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a cell welding and casing machine. Background Technology

[0002] In the battery manufacturing process, cell welding and casing is a crucial step. Existing patents, such as Chinese patent application number 202310586504.5, disclose a battery welding and casing packaging device, including a frame. The frame is equipped with a first indexing turntable, a second indexing turntable, a cell feeding robot, a cell transfer robot, a casing handling and feeding robot, an insulating sheet handling and casing robot, and a discharge handling robot. The second indexing turntable has four cell flipping and casing-inserting mechanisms spaced at intervals. The second indexing turntable rotates counterclockwise by 90 degrees each time. The four cell flipping and casing-inserting mechanisms correspond to four workstations, and can simultaneously hold the casing upright and the cell horizontally. The cell flipping and casing mechanism in this patent document directly flips the cell and forcibly inserts it into the casing. It cannot simulate the human hand action to complete the welding and casing work, which can easily cause the electrode tab solder mark to tear and the casing to scratch the cell. When welding and casing different specifications and models of cells and casings, it is necessary to change the carrier of the corresponding specifications and models, which is troublesome to disassemble and assemble, and has high production costs. In addition, it is necessary to grasp and move the cell multiple times, and it is impossible to perform a second corrective casing after the first casing insertion. It is difficult to guarantee the quality and efficiency of welding and casing insertion.

[0003] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a battery cell welding and casing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A battery cell welding and casing machine includes a first circulating conveying mechanism, a second circulating conveying mechanism arranged parallel to the first circulating conveying mechanism, three six-axis robotic arms 1 equidistantly arranged in the circulating conveying section of the first circulating conveying mechanism, and three six-axis robotic arms 2 equidistantly arranged in the circulating conveying section of the second circulating conveying mechanism. A first region and a second region are provided outside the circulating conveying section of the first circulating conveying mechanism. The first region sequentially houses a battery cell feeding mechanism, a battery cell CCD positioning mechanism, and a tab flattening and shaping mechanism 1. The battery cell CCD positioning mechanism is electrically connected to the six-axis robotic arms 1. The second region sequentially houses a tab appearance inspection and cutting mechanism, a tab flattening and shaping mechanism 2, and a tab insulation sleeve mechanism. A third region is provided between the circulating conveying sections of the first and second circulating conveying mechanisms. The outer side of the circulating conveying section of the second circulating conveying mechanism... The device is equipped with a fourth and a fifth zone. The first, second, and third zones are arranged sequentially along the circulation direction of the circulation conveying section of the first circulation conveying mechanism, and the fourth, third, and fifth zones are arranged sequentially along the circulation direction of the circulation conveying section of the second circulation conveying mechanism. The fourth zone is equipped with a shell loading mechanism, a shell CCD positioning mechanism, and a shell marking mechanism. The shell CCD positioning mechanism is electrically connected to the second six-axis robot. The third zone is equipped with a tab welding mechanism, a tab welding inspection mechanism, and a shell insertion station. The fifth zone is equipped with an insulating adhesive application mechanism, a front shell insertion inspection mechanism, a side shell insertion inspection mechanism, a shell insertion correction mechanism, and a battery unloading mechanism. When both the first and second six-axis robots rotate to the third zone, they work together to simulate manual movements to complete the welding and shell insertion work.

[0007] Furthermore, the second area is also equipped with an upward bending and shaping mechanism for the electrode tab, which is located on the side of the electrode tab sleeve insulating sleeve mechanism away from the second electrode tab flattening and shaping mechanism.

[0008] Furthermore, the third area also includes an AI appearance inspection mechanism, located between the tab welding inspection mechanism and the shell insertion station.

[0009] Furthermore, a barcode scanning mechanism and a flipping mechanism are sequentially installed on the conveying path of the battery cell feeding mechanism. The flipping mechanism is used to flip the battery cell 180°.

[0010] Furthermore, both the first and second circulating conveying mechanisms are rotary conveying mechanisms.

[0011] Furthermore, the fifth area is also equipped with a defective battery output mechanism, which is located between the battery unloading mechanism and the casing correction mechanism.

[0012] Furthermore, a defective casing output mechanism is provided between the casing insertion station and the insulating adhesive application station.

[0013] The beneficial effects of this utility model are as follows: In practical applications, the first cyclic conveying mechanism drives three six-axis robotic arms to move cyclically. Among the three six-axis robotic arms, one six-axis robotic arm is located in the first region, one six-axis robotic arm is located in the second region, and one six-axis robotic arm is located in the third region. The three six-axis robotic arms complete corresponding actions in their respective regions. The second cyclic conveying mechanism drives three six-axis robotic arms to move cyclically. Among the three six-axis robotic arms, one six-axis robotic arm is located in the fourth region, one six-axis robotic arm is located in the third region, and one six-axis robotic arm is located in the fifth region. The three six-axis robotic arms complete corresponding actions in their respective regions. When the six-axis robot is located in the first area, it first picks up the battery cell supplied by the battery cell feeding mechanism, then moves the picked-up battery cell to the battery cell CCD positioning mechanism. The battery cell is visually positioned by the battery cell CCD positioning mechanism, and the visual positioning result of the battery cell is fed back to the six-axis robot, enabling the six-axis robot to perform automatic flexible correction compensation based on the visual positioning result. Then, the battery cell is moved to the tab flattening and shaping mechanism, which flattens and shapes the tabs of the battery cell. Then, the first cycle conveying mechanism drives... Three six-axis robotic arms rotate synchronously to a position within a certain area, allowing the robotic arm picking up the flattened and shaped battery cell to rotate to a second area. The robotic arm then moves the battery cell to the tab appearance inspection and cutting mechanism, which inspects and cuts the tabs of the battery cell. The cut battery cell is then moved to the tab insulation sleeve fitting mechanism, which passes the insulation sleeve through the tab and fits it onto the edge of the battery cell. Next, the first cycle conveying mechanism drives the three six-axis robotic arms to rotate synchronously to a different position within the same area. The six-axis robot arm 1, after picking up the battery cell with the insulated sleeve, rotates to the third area. During this process, when the six-axis robot arm 2 is in the fourth area, it first picks up the housing supplied by the housing loading mechanism, then moves the housing to the housing CCD positioning mechanism. The housing CCD positioning mechanism performs visual positioning on the housing and feeds back the visual positioning result to the six-axis robot arm 2. The six-axis robot arm 2 performs automatic flexible correction compensation based on the visual positioning result, and then moves the battery cell to the housing marking mechanism. The housing marking mechanism marks the housing, and then the second circulating conveyor... The mechanism drives three six-axis robotic arms to rotate synchronously within a designated area. This causes the first six-axis robotic arm, after picking up the coded battery cell, to rotate into a third area. At this point, both the first and second six-axis robotic arms are within the third area. The second six-axis robotic arm moves the housing to the tab welding mechanism, while the first six-axis robotic arm moves the battery cell to the tab welding mechanism, placing the battery cell's tab on a welding position on the inner wall of the housing. The tab welding mechanism then welds the battery cell's tab to this welding position on the inner wall of the housing. Finally, the first and second six-axis robotic arms move synchronously to the tab welding inspection mechanism.The electrode welding inspection mechanism performs welding inspection (weld stamp quality inspection) on the welding between the electrode and the casing of the battery cell. Then, six-axis robots 1 and 2 move synchronously to the casing insertion station. At the casing insertion station, six-axis robots 1 and 2 flexibly cooperate and simulate manual casing insertion, causing the battery cell with welded electrodes to flip into the casing, completing the welding and casing process and forming a preliminary assembled battery. Six-axis robot 1 can then release the battery cell, and six-axis robot 2, picking up the preliminarily assembled battery, rotates to the fifth area. Six-axis robot 2 first moves the preliminarily assembled battery to the insulating adhesive application mechanism, which then applies the insulating adhesive to the preliminarily assembled battery. Insulating tape is applied to the battery cells, which are then moved to the front casing inspection mechanism. The front casing inspection mechanism performs a frontal visual inspection of the cells after casing. The cells after the frontal visual inspection are then moved to the side casing inspection mechanism, which performs a side visual inspection of the cells after casing. The results of the frontal and side visual inspections are fed back to the casing correction mechanism, which corrects the cells after casing by smoothing the separator, simulating human hand movements. This achieves secondary casing without damaging the separator. Finally, the cells after secondary casing are placed on the battery unloading mechanism, which outputs the batteries. In this application, during the cell welding and casing process, both the cell and the casing only require a single gripping operation. Only one visual positioning is needed for each of the loaded cells and casings. The relative positions of the cells on the first six-axis robot and the casing on the second six-axis robot are fixed. This eliminates the need for multiple gripping, handling, and visual positioning operations, preventing the cumulative errors that occur during multiple gripping and handling operations. This significantly improves the quality and efficiency of battery welding and casing installation. Furthermore, the flexible collaboration between the first and second six-axis robots simulates human hand movements, avoiding the tearing of weld lines and scratches caused by directly flipping the cells and forcibly inserting them into the casing. It also enables secondary casing insertion (corrective insertion), ensuring casing quality. The first and second six-axis robots can flexibly correct and compensate for deviations, thus being compatible with various welding processes such as horizontal, inclined, and vertical welding of different cells and casings. Additionally, when welding and casing different specifications of cells and casings, there is no need to change to different carriers, simplifying the operation process and reducing production costs.

[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0018] like Figure 1As shown, the present invention provides a battery cell welding and casing machine, which includes a first circulating conveying mechanism 1, a second circulating conveying mechanism 2 arranged side by side with the first circulating conveying mechanism 1, three six-axis robotic arms 3 equidistantly arranged in the circulating conveying section of the first circulating conveying mechanism 1, and three six-axis robotic arms 4 equidistantly arranged in the circulating conveying section of the second circulating conveying mechanism 2. A first region 5 and a second region 6 are provided on the outer side of the circulating conveying section of the first circulating conveying mechanism 1. The first region 5 is sequentially provided with a battery cell loading mechanism 8, a battery cell CCD positioning mechanism 9, and an electrode tab. The flattening and shaping mechanism 10, the cell CCD positioning mechanism 9 and the six-axis robot 3 are electrically connected. The second region 6 is sequentially provided with the tab appearance inspection and cutting mechanism 11, the tab flattening and shaping mechanism 12 and the tab sleeve insulation mechanism 13. A third region 7 is provided between the circulation conveying section of the first circulation conveying mechanism 1 and the circulation conveying section of the second circulation conveying mechanism 2. A fourth region 14 and a fifth region 15 are provided on the outside of the circulation conveying section of the second circulation conveying mechanism 2. The first region 5, the second region 6 and the third region 7 are along the circulation conveying section of the first circulation conveying mechanism 1. The circulation conveying directions are arranged sequentially. The fourth region 14, the third region 7, and the fifth region 15 are arranged sequentially along the circulation conveying direction of the circulation conveying section of the second circulation conveying mechanism 2. The fourth region 14 is sequentially equipped with a housing loading mechanism 16, a housing CCD positioning mechanism 17, and a housing marking mechanism 18. The housing CCD positioning mechanism 17 is electrically connected to the six-axis robot arm 24. Along the rotation direction of the circulation conveying section of the second circulation conveying mechanism 2, the third region 7 is sequentially equipped with a tab welding mechanism 19, a tab welding inspection mechanism 20, and a housing insertion station 21. The fifth region... 15 is sequentially equipped with an insulating adhesive applicator 22, a front casing inspection mechanism 23, a side casing inspection mechanism 24, a casing correction mechanism 25, and a battery unloading mechanism 26; each six-axis robot 1 3 rotates cyclically to the first region 5, the second region 6, and the third region 7, and each six-axis robot 2 4 rotates cyclically to the fourth region 14, the third region 7, and the fifth region 15; when both six-axis robot 1 3 and six-axis robot 2 4 rotate to the third region 7, the six-axis robot 1 3 and six-axis robot 2 4 flexibly cooperate to simulate human actions to complete the welding and casing work.

[0019] In practical applications, the first cyclic conveying mechanism 1 drives three six-axis robotic arms 3 to move cyclically. Among the three six-axis robotic arms 3, one six-axis robotic arm 3 is located in the first region 5, one six-axis robotic arm 3 is located in the second region 6, and one six-axis robotic arm 3 is located in the third region 7. The three six-axis robotic arms 3 complete corresponding actions in their respective regions. The second cyclic conveying mechanism 2 drives three six-axis robotic arms 4 to move cyclically. Among the three six-axis robotic arms 4, one six-axis robotic arm 4 is located in the fourth region 14, one six-axis robotic arm 4 is located in the third region 7, and one six-axis robotic arm 4 is located in the fifth region 15. The three six-axis robotic arms 4 complete corresponding actions in their respective regions. When the six-axis robot arm 3 is located within the first area 5, it first picks up the battery cell supplied by the battery cell feeding mechanism 8, then moves the picked-up battery cell to the battery cell CCD positioning mechanism 9. The battery cell is visually positioned by the battery cell CCD positioning mechanism 9, and the visual positioning result of the battery cell is fed back to the six-axis robot arm 3, enabling the six-axis robot arm 3 to perform automatic flexible correction compensation based on the visual positioning result. Then, the battery cell is moved to the tab flattening and shaping mechanism 10, which flattens and shapes the tabs of the battery cell. Next, the first circulating conveying mechanism 1 drives three six-axis robotic arms 3 to rotate synchronously to a position within a certain area, causing the six-axis robotic arm 3, which picks up the flattened and shaped battery cell, to rotate into the second area 6. Then, the six-axis robotic arm 3 moves the battery cell to the tab appearance inspection and cutting mechanism 11. The tab appearance inspection and cutting mechanism 11 performs appearance inspection on the tabs of the battery cell and cuts them into shape. Then, the battery cell with the tabs cut into shape is moved to the tab insulation sleeve mechanism 13. The tab insulation sleeve mechanism 13 passes the insulation sleeve through the tab and fits it onto the edge of the battery cell. Then, the first circulating conveying mechanism... 1. The three six-axis robotic arms 1 and 3 are driven to rotate synchronously to a position in a certain area. This causes the six-axis robotic arm 1 and 3, which has picked up the battery cell with the insulated sleeve, to rotate to the third area 7. During this process, when the six-axis robotic arm 2 and 4 are in the fourth area 14, the six-axis robotic arm 2 and 4 first picks up the housing supplied by the housing feeding mechanism 16, and then moves the housing to the housing CCD positioning mechanism 17. The housing CCD positioning mechanism 17 performs visual positioning of the housing and feeds back the visual positioning result to the six-axis robotic arm 2 and 4. The six-axis robotic arm 2 and 4 then performs automatic flexible correction based on the visual positioning result. After compensation, the battery cell is moved to the casing marking mechanism 18, where it marks the casing. Then, the second circulation conveying mechanism 2 drives three six-axis robotic arms 4 to rotate synchronously within a certain area. This causes the six-axis robotic arm 4, which has picked up the marked battery cell, to rotate into the third area 7. At this point, both six-axis robotic arms 3 and 4 are within the third area 7. The six-axis robotic arm 4 moves the casing to the tab welding mechanism 19, and the six-axis robotic arm 3 moves the battery cell to the tab welding mechanism 19, with the battery cell's tab placed on the welding position on an inner side wall of the casing.The electrode welding mechanism 19 welds the electrode of the battery cell to a welding position on the inner side wall of the casing. Then, six-axis robotic arms 1 (3) and 2 (4) move synchronously to the electrode welding inspection mechanism 20. The electrode welding inspection mechanism 20 performs welding inspection (weld quality inspection) on the welding between the electrode of the battery cell and the casing. Next, six-axis robotic arms 1 (3) and 2 (4) move synchronously to the casing insertion station 21. In the casing insertion station 21, six-axis robotic arms 1 (3) and 2 (4) flexibly cooperate and simulate manual casing insertion, causing the battery cell with welded electrode to flip into the casing to complete the welding and casing insertion work, forming a preliminary assembled battery. Six-axis robotic arm 1 (3) can then release the battery cell, and six-axis robotic arm 2 (4) with the preliminary assembled battery rotates to the fifth area 15. Six-axis robotic arm 2 (4) first... The assembled battery is moved to the insulating adhesive applicator 22, where insulating adhesive is applied to the initially assembled battery. The battery with the insulating adhesive is then moved to the front casing inspection mechanism 23, where the front casing inspection mechanism 23 performs a front visual inspection of the casing. The battery with the front visual inspection is then moved to the side casing inspection mechanism 24, where the side casing inspection mechanism 24 performs a side visual inspection of the casing. The results of the front and side visual inspections are fed back to the casing correction mechanism 25, which corrects the casing by smoothing the separator, simulating human hand movements, to achieve secondary casing without damaging the separator. Finally, the battery with secondary casing is placed on the battery unloading mechanism 26, which outputs the battery. In the process of welding and inserting battery cells into the casing, this application requires only one gripping of both the battery cell and the casing. Only one visual positioning is needed for each of the loaded cells and casings. The relative positions of the battery cell and the casing are fixed on the six-axis robotic arm 3 and 4, respectively. This eliminates the need for multiple gripping, handling, and visual positioning of the battery cell and casing, thus preventing the cumulative errors caused by multiple gripping and handling operations. This significantly improves the quality and efficiency of battery welding and casing insertion. Furthermore, the flexible collaboration between the six-axis robotic arms 3 and 4 simulates human hand movements, avoiding the tearing of weld lines and scratches to the battery cell caused by directly flipping and forcibly inserting the battery cell. It also enables secondary insertion (corrective insertion), ensuring insertion quality. The six-axis robotic arms 3 and 4 can flexibly correct and compensate for deviations, thus being compatible with welding processes such as flat welding, tilted welding, and vertical welding of battery cells and casings of different specifications and models. Furthermore, when welding different specifications of battery cells and casings into the housing, there is no need to change the carrier of different specifications, simplifying the operation process and reducing production costs.

[0020] In this embodiment, the second region 6 is also provided with an upward bending and shaping mechanism 27 for the electrode tabs. The upward bending and shaping mechanism 27 for the electrode tabs is located on the side of the electrode tab insulation sleeve mechanism 13 away from the electrode tab flattening and shaping mechanism 12. According to different process requirements, after the insulation sleeve is installed on the battery cell, the six-axis robot 3 moves the battery cell with the insulation sleeve to the upward bending and shaping mechanism 27 for the electrode tabs, and the upward bending and shaping mechanism 27 bends and shapes the electrode tabs of the battery cell upwards.

[0021] In this embodiment, the third region 7 is also equipped with an AI appearance inspection mechanism 28, which is located between the electrode welding inspection mechanism 20 and the casing insertion station 21. After the electrode welding inspection mechanism 20 performs welding inspection on the electrode and casing of the battery cell, the six-axis robot 3 and the six-axis robot 4 move synchronously to the AI ​​appearance inspection mechanism 28 to perform secondary inspection on the welding of the electrode and casing of the battery cell. The AI ​​appearance inspection mechanism 28 will self-learn as the number of inspections increases, continuously optimizing the inspection requirements to ensure welding quality.

[0022] In this embodiment, a barcode scanning mechanism 29 and a flipping mechanism 30 are sequentially arranged on the conveying path of the battery cell feeding mechanism 8. The flipping mechanism 30 is used to flip the battery cell 180°. Before the battery cell feeding mechanism 8 conveys the battery cell to the six-axis robot 3, the barcode scanning mechanism 29 scans the QR code or barcode on the battery cell to identify, track and save the information of the battery cell. Then, the flipping mechanism 30 flips the battery cell 180° to turn the battery cell over.

[0023] In this embodiment, both the first circulating conveying mechanism 1 and the second circulating conveying mechanism 2 are turntable conveying mechanisms, and three six-axis manipulators 1 3 or three six-axis manipulators 2 4 are arranged in a circular array on the turntable of the turntable conveying mechanism.

[0024] In this embodiment, the fifth region 15 is also provided with a defective battery output mechanism 31, which is located between the battery feeding mechanism 26 and the casing correction mechanism 25. The defective battery output mechanism 31 can output defective batteries.

[0025] In this embodiment, a defective casing output mechanism 32 is provided between the casing insertion station 21 and the insulating adhesive application mechanism 22. The defective casing output mechanism 32 can output information about batteries with defective casings.

[0026] All technical features in this embodiment can be freely combined according to actual needs.

[0027] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
