Description

Technical Field

[0001] The present invention belongs to the technical field of battery core shell insertion equipment, and particularly relates to a high-efficiency battery core shell insertion device. Background Art

[0002] The battery cell shelling machine is used to arrange the battery cells and place them into steel shells. It is a device that completes the battery cell shelling operation.

[0003] In the existing technology, the battery cells are often manually arranged and inserted into the steel shell. The operation is cumbersome and complicated, and the efficiency is low. There are also long assembly lines for battery cell arrangement, but the overall operation equipment is long and bulky, the structure is not compact, the floor space is large, the operator has a large working range, the operation is inconvenient, and the room for efficiency improvement is very limited. Summary of the Invention

[0004] The embodiment of the present application provides a high-efficiency battery cell shell insertion device, which solves the problems of complicated battery cell shell insertion operation and non-compact structure through the arrangement of rotating parts and battery cell loading parts, realizes a compact device structure and small footprint, effectively reduces the operating scope of the operator, is simple and quick to operate, and is easy to operate, thereby effectively improving operating efficiency.

[0005] The technical solutions provided by the embodiments of this application are:

[0006] A high-efficiency battery cell shell insertion device includes a rotating component and a battery cell loading component arranged in a circular array on the rotating component; the rotating component includes a first workbench fixedly connected to the battery cell loading component and a guide rail provided at the lower end of the first workbench; the battery cell loading component includes a slider connected to the guide rail, a loading shell provided above the slider and connected to one side of the first workbench, a spring rod connected between the loading shell and the slider, and a movable rod passing through the loading shell and fixedly connected to the slider; the guide rails are provided with guide rails of different heights.

[0007] The cell loading assembly is used to load the cells. A rotating assembly drives the cell loading assembly in stable rotation, facilitating the sequential placement of the cells at each workstation for alignment and final placement into the shells. The rotating assembly can rotate counterclockwise or clockwise. The lower middle portion of the rotating assembly drives the first worktable via an existing rotary motor. The rotation speed is adjustable via the existing control program, effectively ensuring full operation at each workstation.

[0008] The loading shell is used to load the battery cells. The first workbench secures the loading shell and drives the battery cells into the workstations sequentially for operation. The slider slides with the guide rails as the first workbench rotates, providing a foundation for the battery cell loading components to slide along the guide rails at varying heights. The spring rod allows the slider to move up and down with the guide rails at varying heights, thereby driving the movable rod up and down within the loading shell. The movable rod limits the lowest position of the battery cells according to the height of the guide rails, thus supporting the cells.

[0009] In the present invention, by setting guide rails at different heights, it is convenient to provide different heights for battery cells at different workstations, providing a more convenient and efficient environment for operations at each workstation, effectively ensuring the smoothness of operations and the quality of battery cell operations. At the same time, there is no need for a driving source to push the battery cell loading component up and down. The design structure is simple and compact, with a small footprint, and flexible and efficient operations. There is no need to wait for the start and stop time of the driving source to adjust the battery cell height, which greatly shortens the time and improves operation efficiency. By setting a rotating component, the annular array of each link of the battery cell shell is set on the edge of the rotating component. The structural design is compact and ingenious, effectively reducing the equipment footprint, making the operator's work range for observation and maintenance smaller, making the operation simpler and more efficient, and greatly improving operation efficiency.

[0010] Furthermore, it also includes an upper battery cell station, a first lower battery cell station, a tab correction station, a second lower battery cell station, a tab surface pad loading station, a first tab folding station, a first tab pressing station, a first tab detection station, a second tab folding station, a second tab pressing station, a second tab detection station, and a battery cell shelling station, which are arranged in a circular array in sequence and used in conjunction with the battery cell loading station.

[0011] Furthermore, the guide rail includes a first height rail and a second height rail connected end to end with the first height rail; the second height rail is connected to the first height rail on both sides by a first gentle arc rail and a second gentle arc rail respectively; the length of the first height rail accounts for 3 / 5-4 / 5 of the length of the guide rail.

[0012] Furthermore, the second height rail is located at the upper battery cell station; the first gently curved rail is located between the battery cell shell insertion station and the upper battery cell station; and the second gently curved rail is located from the upper battery cell station to the second lower battery cell station.

[0013] Among them, the battery cell tabs include inner tabs and outer tabs. The upper battery cell station is used to load the battery cells to be put into the shell, and the upper battery cell station is located on the second height guide rail, at the track point of the guide rail. The first lower battery cell station is on the second gentle arc rail, and is connected to the subsequent tab correction station. The tab correction station is used to rotate the tabs of the battery cell to the specified position, so as to facilitate the subsequent precise folding of the tabs. The second lower battery cell station is located at the junction of the second gentle arc rail and the first height rail, so as to smoothly lower the battery cell to the first height rail to ensure the height of the battery cell for subsequent work stations. The tab face pad loading station is used to pass the face pad through the tab and put it on the upper surface of the battery cell, wherein the face pad is accurately passed through the tab and placed on the upper surface of the battery cell through the existing face pad clamping equipment. The first tab folding station is used to push the straight inner tab to one direction, so that the inner tab is in an inclined state. The first tab pressing station is used to press the inner tab in a tilted state to a state parallel to the surface of the battery cell, thereby completing the state in which the inner tab is attached to the surface of the battery cell. The first tab detection station is used to detect whether the inner tab has been pressed to the surface of the battery cell and covers the hole in the middle of the battery cell. If the detection is qualified, the operation continues; if the detection is unqualified, the operation is stopped to alert the operator. The second tab folding station is used to push the straight outer tab in one direction to make the outer tab in a tilted state. The second tab pressing station is used to press the outer tab in a tilted state onto the surface of the battery cell, thereby completing the state in which the outer tab is attached to the surface of the battery cell. The second tab detection station is used to detect whether the outer tab has been pressed to the surface of the battery cell and covers the hole in the middle of the battery cell. If the detection is qualified, the operation continues; if the detection is unqualified, the operation is stopped to alert the operator. The battery cell shelling station is used to insert the battery cell into the steel shell, thereby completing the battery cell shelling operation.

[0014] Through the above settings, the process of battery cell shelling is as follows: through the rotating parts, the upper battery cell station, the first lower battery cell station, the tab correction station, the second lower battery cell station, the tab surface pad loading station, the first tab folding station, the first tab pressing station, the first tab detection station, the second tab folding station, the second tab pressing station, the second tab detection station, and the battery cell shelling station are carried out in sequence, and the battery cell shelling operation is carried out in a cycle, which effectively improves the operation rhythm and the operation process is simple and fast. Among them, the battery cell shelling station is located in the first flat arc rail from the battery cell shelling station to the upper battery cell station, and the upper battery cell station is located on the second height rail to facilitate the placement of the battery cell. The upper battery cell station is located in the second flat arc rail to the second lower battery cell station, and the tab surface pad loading station to the battery cell shelling station is located on the first height rail. Through the setting of the guide rails and stations, the height of different battery cell loading components at different stations is met, so that the battery cell shelling process is smooth and the battery cell shelling quality is improved. By setting the first gently curved rail and the second gently curved rail, the movable rod can be raised and lowered in an orderly and stable manner, effectively ensuring the stability of the movable rod's lifting speed, effectively protecting the device, extending the service life of the device, and reducing the maintenance frequency.

[0015] Furthermore, the rotating component also includes a second workbench located in the middle of the upper end of the first workbench; the area of the second workbench is smaller than that of the first workbench. The first workbench is driven to rotate by an existing rotating motor, while the second workbench is fixed and does not rotate. The provision of the second workbench facilitates the placement of components at each workstation, effectively improving operational stability. Furthermore, since the components are placed on the second workbench and the second workbench is located on the first workbench, it is higher than the first workbench, creating a height difference. This facilitates the installation of components at each workstation, reduces the height of components at each workstation, lowers the center of gravity of components at each workstation, and improves operational stability.

[0016] Furthermore, the tab correction station includes a second fixed block fixedly connected to the second workbench, a tab sensor provided on the second fixed block and provided on the upper end of the battery cell loading component, and a roller slidably connected to the second fixed block and provided on one side of the loading shell. The rotation of the roller is controlled by an existing program, and the sliding of the roller close to the battery cell is achieved by an existing push cylinder. The operation process of the tab correction station is as follows: when the tab sensor senses that the tab of the battery cell is not in the specified position, the tab sensor sends a start signal to the control program, driving the roller to approach the battery cell and directly contact the battery cell, then stops sliding, and then rotates the roller to drive the battery cell until the tab is rotated to the specified position. The tab sensor sends a stop signal to the control program, causing the roller to stop rotating and return to its original position. Through the above-mentioned setting, the accuracy of the tab rotation is effectively guaranteed, which is convenient for subsequent stable and precise operation; the second fixed block effectively ensures stability during the tab correction operation.

[0017] Furthermore, the first tab folding station includes a third fixed block fixedly connected to the second workbench, a sliding push rod fixedly connected to the third fixed block and provided on one side of the loading shell; the second tab folding station includes a fourth fixed block fixedly connected to the second workbench, a first lifting and pressing block fixedly connected to the fourth fixed block and provided on the upper end of the loading shell. Among them, the sliding push rod is realized by an existing pushing cylinder. The first lifting and pressing block realizes lifting and lowering motion by an existing lifting cylinder. The surface of the first lifting and pressing block in contact with the tab is an inclined surface, which facilitates pushing the outer tab to one direction. The operation process of the tab folding station is as follows: when the battery cell reaches the first tab folding station, the sliding push rod approaches the inner tab and pushes the inner tab to a certain inclination with the surface of the battery cell, completing the action of folding the inner tab, and the sliding push rod returns to its original position. When the battery cell reaches the second tab folding station, the first lifting and pressing block moves downward toward the outer tab. The outer tab is then pressed down along the inclined surface of the first lifting and pressing block until it forms a certain angle with the battery cell surface, completing the outer tab folding operation. The first lifting and pressing block then rises to its original position. This arrangement allows the tab to be quickly pressed to a certain angle with the battery cell surface, facilitating the subsequent accurate tab pressing. The flexible and ingenious structural design ensures convenient and efficient tab folding. The third and fourth fixing blocks effectively ensure stability during the tab folding operation.

[0018] Furthermore, the first tab pressing station includes a fifth fixed block fixedly connected to the second workbench, and a second lifting and pressing block fixedly connected to the fifth fixed block and arranged at the upper end of the loading shell; the structure of the first tab pressing station is the same as that of the second tab pressing station. Among them, the second lifting and pressing block adopts an existing lifting cylinder to achieve lifting movement. The operation process of the tab pressing station is as follows: when the battery cell moves from the first tab folding station to the first tab pressing station, the second lifting and pressing block presses the inner tab downward to a state parallel to the surface of the battery cell, and covers the hole in the middle of the battery cell, thereby completing the inner tab pressing operation. The second tab pressing station presses the outer tab to the surface of the battery cell through the same working process as mentioned above. Through this setting, the inner and outer tabs are effectively pressed to the surface of the battery cell, ensuring the quality of the tab pressing, and the structural design is compact, the operation is sensitive, and the operation efficiency is effectively guaranteed. The setting of the fifth fixed block effectively ensures the stability of the tab pressing and the smoothness of the operation.

[0019] Furthermore, the first tab detection station includes a sixth fixed block fixedly connected to the second workbench, and a CCD detection body fixedly connected to the sixth fixed block and arranged at the upper end of the loading shell; the structure of the first tab detection station is the same as that of the second tab detection station. The CCD detection body is used to detect whether the tab is properly attached to the surface of the battery cell. First, a qualified state diagram of the tab attached to the surface of the battery cell is recorded in the control program. During the operation of the CCD detection body, the state diagram of the current tab attached to the surface of the battery cell is photographed, and the existing control program and the qualified state diagram are compared to achieve detection. If the detection is qualified, the operation continues; if the detection is unqualified, the operation is stopped and the operator is prompted. Through this setting, the quality of the tab pressing is effectively guaranteed and the production yield is effectively improved. The setting of the sixth fixed block effectively guarantees the stability of the operation process of the CCD detection body and ensures the detection accuracy of the CCD detection body.

[0020] Furthermore, the cell shelling station includes a seventh fixed block fixedly connected to the second workbench, a pressure sensor fixedly connected to the seventh fixed block and located at the upper end of the loading shell, and a lifting block located at the lower end of the slider. The lifting block is raised and lowered by an existing lifting cylinder. The cell shelling process is as follows: the steel shell is clamped to the lower end of the pressure sensor using an existing clamp, with the steel shell opening facing the cell. The lifting block rises, pushing the slider upward, thereby moving the movable rod upward. The movable rod lifts the cell and allows it to enter the steel shell. When the cell reaches the uppermost portion of the steel shell, it moves the steel shell upward onto the pressure sensor. When the pressure sensor reaches the set pressure value, the lifting block moves downward to its original position. Simultaneously, the existing clamp moves a baffle below the steel shell to further prevent the cell from falling. The clamp then moves the loaded steel shell to the finished product storage area, completing the cell shelling process. This arrangement effectively ensures stable and efficient cell shelling, simple and efficient operation, and a compact structure, effectively improving operational efficiency. The setting of the seventh fixing block effectively ensures the stable operation of the pressure sensor, effectively and accurately senses the pressure value, ensures the accuracy of the operation, and improves the quality of battery cell shell insertion.

[0021] Through the above settings, the operations at each workstation are compact and the operation rhythm is strong, which effectively improves the overall operation time and the efficiency of batch shelling of battery cells.

[0022] Beneficial effects of the present invention:

[0023] By setting up rotating parts and battery cell loading parts, the problems of complicated operation and non-compact structure of existing battery cell shelling are solved, and the device structure is compact and occupies a small area, which effectively reduces the working scope of the operators, makes the operation simple and fast, and is easy to operate, effectively improving the working efficiency.

[0040] The cell loading assembly 2 is used to load the cells. The rotating assembly 1 is used to drive the cell loading assembly 2 in stable rotation, facilitating the sequential placement of the cells at each workstation for alignment and final placement of the cells into their shells. The rotating assembly 1 can rotate either counterclockwise or clockwise. The lower middle portion of the rotating assembly 1 is driven by an existing rotary motor to rotate the first worktable 1-1. The rotation speed can be adjusted using an existing control program to effectively meet the needs of each workstation for full operation.

[0041] The loading shell 2-2 is used to load the battery cells. The first workbench 1-1 is used to secure the loading shell 2-2, driving the battery cells into the workstations one by one for operation. The slider 2-1 is used to slide with the guide rail 1-2 when the first workbench 1-1 rotates, and provides a foundation for the battery cell loading component 2 to slide along the guide rails 1-2 at different heights. The spring rod 2-3 is used to allow the slider 2-1 to move up and down with the guide rails 1-2 at different heights, thereby driving the movable rod 2-4 to move up and down within the loading shell 2-2. The movable rod 2-4 is used to limit the lowest position of the battery cells according to the height of the guide rail 1-2, thereby supporting the battery cells.

[0042] In the present invention, by setting different heights of the guide rails 1-2, it is convenient to provide different heights for the battery cells at different workstations, providing a more convenient and efficient environment for the operation of each workstation, effectively ensuring the smoothness of the operation and the quality of the battery cell operation. At the same time, there is no need for a driving source to push the battery cell loading component 2 up and down. The design structure is simple and compact, the floor space is small, and the operation is flexible and efficient. Moreover, there is no need to wait for the start and stop time of the driving source to adjust the height of the battery cell, which greatly shortens the time and improves the operation efficiency. By setting the rotating component 1, the annular array of each link of the battery cell shell is set on the edge of the rotating component 1. The structural design is compact and ingenious, effectively reducing the equipment footprint, making the operator's observation and maintenance work range smaller, making the operation simpler and more efficient, and greatly improving the operation efficiency.

The second lower battery cell station 6 is located at the junction of the second gentle arc rail 1-24 and the first height rail 1-21, so as to smoothly lower the battery cell to the first height rail 1-21, ensuring the height of the battery cell for subsequent work stations. The tab face pad loading station 7 is used to pass the face pad through the tab and put it on the upper surface of the battery cell, wherein the face pad is accurately passed through the tab and placed on the upper surface of the battery cell through the existing face pad clamping equipment. The first tab folding station 8 is used to push the straight inner tab in one direction so that the inner tab is in an inclined state. The first tab pressing station 9 is used to press the inner tab in an inclined state to a state parallel to the surface of the battery cell, thereby completing the state of the inner tab attached to the surface of the battery cell. The first tab detection station 10 is used to detect whether the inner tab has been pressed to the surface of the battery cell and covers the hole in the middle of the battery cell. If the test is qualified, the operation continues; if the test is unqualified, the operation is stopped to remind the operator. The second tab folding station 11 is used to push the straight outer tab in one direction so that the outer tab is in an inclined state.

If the test is qualified, the operation continues; if the test is unqualified, the operation is stopped to remind the operator. The battery cell shell insertion station 14 is used to insert the battery cell into the steel shell, thereby completing the battery cell shell insertion operation.

[0047] Through the above settings, the battery cell shelling operation process is: through the rotating component 1, the upper battery cell station 3, the first lower battery cell station 4, the tab correction station 5, the second lower battery cell station 6, the tab surface pad loading station 7, the first tab folding station 8, the first tab pressing station 9, the first tab detection station 10, the second tab folding station 11, the second tab pressing station 12, the second tab detection station 13, and the battery cell shelling station 14 are carried out in sequence.

By setting the guide rail 1-2 and the station, the height of different battery cell loading components 2 at different stations is met, so that the battery cell shelling process is smooth and fluent, and the battery cell shelling quality is improved. By setting the first gentle arc rail 1-23 and the second gentle arc rail 1-24, the movable rod 2-4 is raised and lowered in an orderly and stable manner, effectively ensuring the stability of the lifting rate of the movable rod 2-4, effectively protecting the device, extending the service life of the device, and reducing the maintenance frequency.

[0048] In one embodiment, the rotating component 1 also includes a second workbench 1-3 provided in the middle of the upper end of the first workbench 1-1; the area of the second workbench 1-3 is smaller than that of the first workbench 1-1. The first workbench 1-1 is driven to rotate by an existing rotating motor, and the second workbench 1-3 is fixed and does not rotate. By providing the second workbench 1-3, it is convenient to place the components of each workstation, and the stability of the operation is effectively improved. Moreover, by placing the components on the second workbench 1-3, since the second workbench 1-3 is provided on the first workbench 1-1, the second workbench 1-3 is higher than the first workbench 1-1, and there is a height difference, which facilitates the installation of components at each workstation, reduces the height of the components at each workstation, lowers the center of gravity of the components at each workstation, and improves the stability of the operation.

[0049] In one embodiment, the tab correction station 5 includes a second fixed block 5-1 fixedly connected to the second workbench 1-3, a tab sensor provided on the second fixed block 5-1 and on the upper end of the battery cell loading component 2, and a roller 5-2 slidably connected to the second fixed block 5-1 and provided on one side of the loading shell 2-2. The rotation of the roller 5-2 is controlled by an existing program, and the sliding of the roller 5-2 close to the battery cell is achieved by an existing push cylinder. The operation process of the tab correction station 5 is as follows: when the tab sensor senses that the tab of the battery cell is not in the specified position, the tab sensor sends a start signal to the control program, driving the roller 5-2 to approach the battery cell and directly contact the battery cell, then stop sliding, and then rotate the roller 5-2 to drive the battery cell until the tab is rotated to the specified position. The tab sensor sends a stop signal to the control program, causing the roller to stop rotating and return to its original position. Through the above-mentioned arrangement, the accuracy of the tab rotation is effectively guaranteed, which facilitates subsequent stable and precise operation; the second fixed block 5-1 effectively ensures stability during the tab correction operation.

[0050] In one embodiment, the first tab folding station 8 includes a third fixed block 8-1 fixedly connected to the second workbench 1-3, and a sliding push rod 8-2 fixedly connected to the third fixed block 8-1 and provided on one side of the loading shell 2-2; the second tab folding station 11 includes a fourth fixed block 11-1 fixedly connected to the second workbench 1-3, and a first lifting and pressing block 11-2 fixedly connected to the fourth fixed block 11-1 and provided on the upper end of the loading shell 2-2. The sliding push rod 8-2 is implemented by an existing pushing cylinder. The first lifting and pressing block 11-2 is implemented by an existing lifting cylinder to achieve lifting motion. The surface of the first lifting and pressing block 11-2 in contact with the tab is an inclined surface, which is convenient for pushing the outer tab to one direction. The operation process of the tab folding station is as follows: when the battery cell reaches the first tab folding station 8, the sliding push rod 8-2 approaches the inner tab and pushes the inner tab to a certain inclination with the surface of the battery cell, completing the inner tab folding action, and the sliding push rod 8-2 returns to its original position. When the battery cell reaches the second tab folding station 11, the first lifting and pressing block 11-2 moves downwardly close to the outer tab, and the outer tab is pressed down along the inclined surface of the first lifting and pressing block 11-2 to a certain inclination with the surface of the battery cell, thereby completing the outer tab folding action, and the first lifting and pressing block 11-2 rises to its original position. Through this setting, the tab is quickly pressed to a certain inclination with the surface of the battery cell, which facilitates the accuracy of subsequent tab pressing. The structural design is flexible and ingenious, ensuring that the tab folding is convenient and efficient. The third fixed block 8-1 and the fourth fixed block 11-1 effectively ensure stability during the tab folding operation.

[0051] In one embodiment, the first tab pressing station 9 includes a fifth fixed block 9-1 fixedly connected to the second workbench 1-3, and a second lifting and pressing block 9-2 fixedly connected to the fifth fixed block 9-1 and located at the upper end of the loading shell 2-2. The structure of the first tab pressing station 9 is the same as that of the second tab pressing station 12. The second lifting and pressing block 9-2 uses an existing lifting cylinder to achieve lifting movement. The tab pressing station operation process is as follows: when the battery cell moves from the first tab folding station 8 to the first tab pressing station 9, the second lifting and pressing block 9-2 presses the inner tab downwardly until it is parallel to the battery cell surface and covers the hole in the middle of the battery cell, thereby completing the inner tab pressing operation. The second tab pressing station 12 presses the outer tab to the battery cell surface through the same process as described above. Through this arrangement, the inner and outer tabs are effectively pressed against the battery cell surface, ensuring the quality of the tab pressing. The structural design is compact and the operation is sensitive, effectively ensuring operational efficiency. The setting of the fifth fixing block 9 - 1 effectively ensures the stability of the pressure tab and the smoothness of operation.

[0052] In one embodiment, the first tab inspection station 10 includes a sixth fixed block 10-1 fixedly connected to the second workbench 1-3, and a CCD detector 10-2 fixedly connected to the sixth fixed block 10-1 and located at the upper end of the loading shell 2-2. The structure of the first tab inspection station 10 is identical to that of the second tab inspection station 13. The CCD detector 10-2 is used to detect whether the tabs are properly attached to the battery cell surface. A control program first records a qualified state image of the tabs attached to the battery cell surface. During operation, the CCD detector 10-2 captures the current state image of the tabs attached to the battery cell surface and compares it with the qualified state image using the existing control program to perform the inspection. If the inspection passes, the operation continues; if the inspection fails, the operation is stopped and the operator is notified. This configuration effectively ensures the quality of the tab pressing and improves production yield. The sixth fixed block 10-1 effectively ensures the stability of the CCD detector 10-2 operation and ensures the accuracy of the inspection.

[0053] In one embodiment, the battery cell shelling station 14 includes a seventh fixed block 14-1 fixedly connected to the second workbench 1-3, a pressure sensor 14-2 fixedly connected to the seventh fixed block 14-1 and disposed at the upper end of the loading shell 2-2, and a lifting block disposed at the lower end of the slider 2-1. The lifting block is raised and lowered by an existing lifting cylinder. The battery cell shelling process is as follows: the steel shell is clamped to the lower end of the pressure sensor 14-2 using an existing clamp, with the opening of the steel shell facing the battery cell. The lifting block rises, pushing the slider 2-1 upward, thereby driving the movable rod 2-4 upward. The battery cell is lifted by the movable rod 2-4 and then enters the steel shell. When the battery cell reaches the top of the steel shell, it drives the steel shell upward to the pressure sensor 14-2. When the pressure sensor 14-2 reaches the set pressure value, the lifting top block moves downward back to its original position. At the same time, the existing clamp moves out the baffle under the steel shell to further prevent the battery cell from falling. The loaded steel shell is moved to the place where the finished product is placed through the existing clamp, thereby completing the battery cell shelling operation. Through this setting, the stability and efficiency of the battery cell shelling are effectively guaranteed, the operation is efficient and simple, the structure is compact, and the compactness of the operation is effectively improved. The setting of the seventh fixed block 14-1 effectively guarantees the stable operation of the pressure sensor 14-2, effectively and accurately senses the pressure value, ensures the accuracy of the operation, and improves the quality of the battery cell shelling.

[0054] Through the above settings, the operations at each workstation are compact and the operation rhythm is strong, which effectively improves the overall operation time and the efficiency of batch shelling of battery cells.

[0055] Beneficial effects of the present invention:

[0056] By setting the rotating component 1 and the battery cell loading component 2, the problems of complicated operation and non-compact structure of the existing battery cell shelling are solved, the device structure is compact, the footprint is small, the working scope of the operator is effectively reduced, the operation is simple and fast, and it is easy to operate, which effectively improves the working efficiency.
