The alignment time plus the logistics time of transporting battery cells limits the high-speed and efficient operation of the machine. For machines that require efficient production, it is completely unable to meet the production needs.

[0004] Therefore, in order to solve the above problems, a turret-type uninterrupted automatic tab alignment device is proposed. Summary of the Invention

For machines that require efficient production, it is completely unable to meet the production needs. The present invention proposes a turret-type uninterrupted automatic tab alignment device.

[0007] A turntable assembly, used to accommodate and adjust the position of the battery cells;

[0008] The ear-finding component locates the battery cell's tabs by driving the battery cell to rotate;

[0009] The bending mechanism is used to bend the battery cell tabs.

The battery cell placement seat is arranged on the outer edge of the turntable seat, the lifting mechanism is located on the lower side of the turntable seat, and the lifting mechanism is installed on the lower cam.

[0011] Furthermore, when the battery cell placement seat drives the battery cell to the specified position, the lifting mechanism is used to lift the battery cell placed in the battery cell placement seat.

The lower side of the battery cell placement seat is a through-hole structure, and the lifting mechanism can be inserted into the battery cell placement seat.

[0012] Preferably, the turntable seat is provided with a plurality of equally distributed positioning holes on the same circular ring and a limiting groove corresponding to each positioning hole is provided on the inner circular ring, and each relative positioning hole and limiting groove are located on the same radius of the turntable seat.

[0013] Furthermore, the positioning hole and limiting groove combination structure is used to limit the separate lower cam and battery cell placement seat combination structure to prevent offset on the turntable seat from affecting the operation process. The positioning hole is connected to the lower cam and the battery cell placement seat to ensure that the lifting mechanism can be stably inserted when it is in the specified position.

[0014] Preferably, the turntable seat is configured as a double layer, the positioning hole passes through the lower layer of the turntable seat and is connected to the lower cam, and the limiting groove is located in the upper layer of the turntable seat for limiting the lower cam, which is conducive to limiting, has a simple structure and is easy to use.

[0017] The first positioning mechanism and the second positioning mechanism are used to clamp the battery cell. The second positioning mechanism drives the battery cell to rotate, thereby rotating the battery cell. When the sensor senses the tab, the rotation stops. The tab bending mechanism moves forward and bends the tab to a certain angle. Then the bending mechanism is reset, which is beneficial to improve production efficiency.

[0021] Furthermore, the cam groove of the second follower wheel through the disc-type cam pushes the driving wheel mechanism to press against the other side of the battery cell. At the same time, the motor drives the driving wheel to rotate, and the driving wheel drives the battery cell to rotate until the sensor detects that the pole ear of the battery cell is in the set position. The motor stops, which is convenient for quickly positioning the other side of the battery cell and rotating to find the pole ear, which is conducive to improving work efficiency.

[0022] Preferably, the outer surface of the disc cam is configured as a concave-convex surface, and as the disc cam continues to rotate, the third follower wheel is pushed out by the concave-convex surface of the outer surface of the disc cam.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] A turntable assembly, used to accommodate and adjust the position of the battery cells;

[0037] The ear-finding component locates the battery cell's tabs by driving the battery cell to rotate;

[0038] The bending mechanism is used to bend the battery cell tabs, and the bending mechanism adopts a folding knife.

[0039] In this embodiment, the turntable assembly includes a turntable seat 1, a lower cam 2, a lifting mechanism 3, and a battery cell placement seat 4. The battery cell placement seat 4 is arranged on the outer edge of the turntable seat 1, the lifting mechanism 3 is located on the lower side of the turntable seat 1, and the lifting mechanism 3 is installed on the lower cam 2.

[0040] Furthermore, when the battery cell placement seat 4 drives the battery cell to the specified position, the lifting mechanism 3 is used to lift the battery cell placed in the battery cell placement seat 4. The lifting mechanism can be a lifting cylinder. The lower side of the battery cell placement seat 4 is a through-hole structure, and the lifting mechanism 3 can be inserted into the battery cell placement seat 4.

[0041] In this embodiment, the turntable seat 1 is provided with multiple equally distributed positioning holes 5 on the same circular ring and a limiting groove 6 corresponding to each positioning hole 5 is provided on the inner circular ring, and each relative positioning hole 5 and limiting groove 6 is located on the same radius of the turntable seat 1.

[0042] Furthermore, the combined structure of the positioning hole 5 and the limiting groove 6 is used to limit the combined structure of the separate lower cam 2 and the battery cell placement seat 4 to prevent offset on the turntable seat 1 from affecting the operation process. The positioning hole 5 is connected to the lower cam 2 and the battery cell placement seat 4 to ensure that the lifting mechanism 3 can be stably inserted when it is in the specified position.

[0043] In this embodiment, the turntable seat 1 is configured as a double layer, the positioning hole 5 passes through the lower layer of the turntable seat 1 and is connected to the lower cam 2, and the limiting groove 6 is located on the upper layer of the turntable seat 1 for limiting the lower cam 2, which is conducive to limiting, has a simple structure and is easy to use.

[0044] In this embodiment, the ear finding assembly includes an upper cam 7, a first positioning mechanism, a second positioning mechanism, a sensor 8, and a disc-shaped cam 9. The upper cam 7 is located on one side of the first positioning mechanism. The first positioning mechanism and the second positioning mechanism are respectively located on both sides above the battery cell placement seat 4. The sensor 8 is located above the battery cell placement seat 4, and the disc-shaped cam 9 is connected to the second positioning mechanism.

[0045] In this embodiment, when the ear-finding assembly positions the battery cell, a triangle is formed between the first positioning mechanism, the second positioning mechanism, and the battery cell.

[0046] The first positioning mechanism and the second positioning mechanism are used to clamp the battery cell. Two driven wheels and one driving wheel form a triangle to form a stable clamp. The second positioning mechanism drives the battery cell to rotate, thereby rotating the battery cell. When the sensor 8 senses the tab, the rotation stops. The tab bending mechanism moves forward to bend the tab to a certain angle, and then the bending mechanism is reset, which is beneficial to improve production efficiency.

[0047] In this embodiment, the first positioning mechanism includes a first follower wheel 10, a sliding frame 11, a sliding rail 12, and a driven wheel mechanism 13. The first follower wheel 10 is located on the inner side of the upper cam 7, and the first follower wheel 10 is movably connected to the sliding frame 11. The driven wheel mechanism 13 is installed on the lower side of the sliding frame 11, and the driven wheel mechanism 13 is located above one side of the battery cell placement seat 4. The sliding frame 11 and the driven wheel mechanism 13 are rotationally connected.

[0048] Furthermore, when the upper cam 7 rotates, the upper cam 7 squeezes the first follower wheel 10 inward, causing the driven wheel mechanism to slide along the direction of the slide rail, and the driven wheel on the driven wheel mechanism is pressed against one side of the battery cell. Other structures can also be used for replacement. When the upper cam 7 rotates, it can be pressed inward against one side of the battery cell to position the battery cell.

[0049] In this embodiment, the second positioning mechanism includes a mounting seat 14, a movable seat 15, a second follower wheel 16, a connecting plate 18, and a driving wheel mechanism 19. The driving wheel mechanism 19 is installed at one end of the connecting plate 18, and the driving wheel mechanism 19 is close to the side of the battery cell placement seat 4, and the driving wheel mechanism 19 includes a driving wheel and a motor. The second follower wheel 16 is movably connected to the other end of the connecting plate 18, and the connecting plate 18 is movably connected in the cam groove of the disc cam 9. The movable seat 15 and the mounting seat 14 are slidably connected; the bending mechanism includes a third follower wheel 17 and a folding knife 21. The connecting rod of the third follower wheel 17 is slidably connected to the connecting plate 18, and one end of the third follower wheel 17 is attached to the outer wall of the disc cam 9. The third follower wheel 17 is installed at one end of the movable seat 15, and the folding knife 21 is installed at the other end of the movable seat 15.

[0050] Furthermore, the second follower wheel 16 pushes the driving wheel mechanism 19 to be pressed against the other side of the battery cell through the cam groove of the disc cam. At the same time, the motor drives the driving wheel to rotate, and the driving wheel drives the battery cell to rotate until the sensor detects that the pole ear of the battery cell is in the set position. The motor stops, which is convenient for quickly positioning the other side of the battery cell and rotating to find the pole ear, which is conducive to improving work efficiency.

[0051] In this embodiment, the outer surface of the disc cam 9 is configured as a concave-convex surface.

[0052] Furthermore, due to the spring action between the mounting seat 14 and the movable seat 15, the outer edge of the disc cam 9 is pressed against the third follower wheel 17. Therefore, when the disc cam 9 rotates relative to the third follower wheel 17, due to the irregular side surface of the disc cam 9, the disc cam 9 pushes the third follower wheel 17, causing the folding knife 21 to slide relative to the mounting seat 14, and the tab bending mechanism starts to move forward, pushing the tab to bend a certain angle.

[0053] In this embodiment, two positioning posts 20 are provided on the mounting seat 14 , and the movable seat 15 is mounted on the mounting seat 14 via one positioning post 20 . A spring is provided between the positioning posts 20 to facilitate pressing the third follower wheel 17 tightly against the disc cam 9 .

[0054] In summary, in the turret-type uninterrupted automatic tab alignment device, the turntable seat 1 keeps rotating synchronously, the upper cam 7 and the disc-shaped cam 9 are fixed, the battery cell is in the battery cell placement seat 4, and when the lower cam 2 is transported to the specified position, the lifting mechanism 3 pushes up, pushing the battery cell from the battery cell placement seat 4 to a certain height to reduce the friction between the battery cell and the battery cell placement seat when the battery cell rotates. The driven wheel mechanism 13 and the driving wheel mechanism 19 move in the direction of the winding core respectively, thereby clamping the battery cell in a triangular state, and the second follower wheel 16 is pushed to the driving wheel mechanism 19 through the cam groove of the disc-shaped cam 9 and pressed against the other side of the battery cell. The motor on the driving wheel mechanism 19 drives the driving wheel to rotate, causing the battery cell to rotate; the motor stops until the sensor 8 detects that the battery cell's tab is in the set position; the disc cam 9 is fixed, and the third follower wheel 17 is pushed out by the outer surface of the disc cam 9 to overcome the spring resistance, and the tab bending mechanism starts to move forward, pushing the tab to bend a certain angle, and then the tab bending mechanism returns to its original position, and the driven wheel mechanism 13 and the driving wheel mechanism 19 return to the opposite direction of the battery cell, and the lifting mechanism 3 drives the winding core back to the battery cell placement seat 4, and then discharges the turntable to complete the action of this mechanism.
