[0040] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0041] like Figure 1 and Figure 2As shown, a cell stacking and boxing mechanism according to a preferred embodiment of the present invention comprises a frame 1, wherein the frame 1 has a first direction (X), a second direction (Y) and a third direction (Z) intersecting with each other, wherein the first direction (X) is the width direction of the frame 1, the second direction (Y) is the length direction of the frame 1, and the third direction (Z) is the height direction of the frame 1; preferably, the first direction (X), the second direction (Y) and the third direction (Z) are arranged perpendicular to each other.

[0042] A bracket 2 is arranged in the frame 1, and the bracket 2 adopts an L-shaped structure, which includes a vertical end plate 21 extending in the third direction and a horizontal end plate 22 extending in the second direction; a clamping fixture 3 for accommodating battery cells is arranged in the bracket 2, and the clamping fixture 3 is arranged as a standard rectangular structure with an accommodating cavity inside, so that the battery cells can be neatly stacked in the clamping fixture 3; a lifting mechanism 8 is arranged on one side of the third direction (Z) of the clamping fixture 3, a box-entry mechanism 4 is arranged on one side of the first direction (X) of the clamping fixture 3, and a side pushing mechanism 5 and a flipping mechanism 6 are respectively arranged on both sides of the second direction (Y) of the clamping fixture 3; the clamping fixture 3 has an opening 31, and the opening 31 is used for the entry and exit of the battery cells. The opening 31 can be closed during operation to prevent the battery cells from directly sliding out of the opening 31 during the flipping process.

[0043] The flipping mechanism 6 is arranged on the second direction (Y) of the bracket 2, and is used to drive the clamping fixture 3 to rotate; the flipping mechanism 6 includes a first driving mechanism 61, and the first driving mechanism 61 is arranged on the vertical end plate 21 of the bracket 2, and is respectively located at both ends of the vertical end plate 21 with the clamping fixture 3 in the second direction (Y); the first driving mechanism 61 passes through the vertical end plate 21 and is connected to the clamping fixture 3, and the first driving mechanism 61 can drive the clamping fixture 3 to rotate with a straight line parallel to the second direction (Y) as the axis, so that the clamping fixture 3 has freedom in the torque direction.

[0044] The side pushing mechanism 5 is arranged in the second direction (Y) of the bracket 2. The side pushing mechanism 5 includes a second driving mechanism 51 and a positioning pin 52. The positioning pin 52 can be slidably arranged in the second direction (Y) of the clamping fixture 3. The second driving mechanism 51 can push the positioning pin 52 to insert into the clamping fixture 3 along the second direction (Y). After the positioning pin 52 is inserted into the clamping fixture 3, the battery cell is kept fixed in the second direction (Y) and the first direction (X) in the clamping fixture 3, so that the battery cells are stacked neatly during the rotation process, and it is also ensured that the clamping fixture 3 will not be displaced in the second direction (Y).

[0045] The lifting mechanism 8 is arranged in the third direction (Z) of the bracket 2. The lifting mechanism 8 includes a third driving mechanism 81 and a lifting plate 82. The lifting plate 82 is arranged in parallel with the horizontal end plate 22 of the bracket 2. The lifting plate 82 is arranged between the horizontal end plate 22 of the bracket 2 and the clamping fixture 3, so that the movement of the lifting plate 82 will not interfere with the bracket 2; the end face of the lifting plate 82 is arranged toward the clamping fixture 3, and the third driving mechanism 81 can drive the lifting plate 82 to move along the third direction (Z) to approach the opening 31 of the clamping fixture 3 in the third direction (Z), so that after the rotating clamping fixture 3 is unsealed at the opening 31, the battery cell can fall onto the lifting plate 82 under the action of its own gravity, and can smoothly escape from the clamping fixture 3 as the lifting plate 82 moves in the third direction (Z).

[0046] The box-entering mechanism 4 is arranged in the first direction (X) of the bracket 2. The box-entering mechanism 4 includes a box-entering platform 41 and a pushing mechanism 42. The height of the box-entering platform 41 is flush with the height of the lifting plate 82 after it moves down. After the lifting plate 82 drives the battery cells to move down, the battery cells can be moved to the box-entering platform 41 with the lifting plate 82 by workers manually or mechanically. The box-entering platform 41 is provided with a chassis 44 for accommodating the battery cell group on one side in the second direction (Y). The pushing mechanism 42 can move in the second direction (Y) to push the neatly stacked battery cells on the box-entering platform 41 directly into the chassis 44 to complete the packing of the battery cells.

[0047] When the embodiment of the present application is working, a plurality of battery cells are first placed in the clamping jig 3 through the opening 31, and the worker closes the opening 31 of the clamping jig 3 manually or mechanically, and then the second driving mechanism 51 of the side-pushing mechanism 5 inserts the positioning pin 52 into the clamping jig 3 in the second direction (Y), so that the battery cells in the clamping jig 3 are stacked neatly and maintained fixed, and at this time the first driving mechanism 61 of the flipping mechanism 6 rotates the clamping jig 3 until the opening 31 is aligned with the lifting plate 82 of the lifting mechanism 8, and the third driving mechanism 81 of the lifting mechanism 8 drives the lifting plate 82 to move toward the clamping jig 3 in the third direction (Z) until it abuts against The clamping fixture 3 faces one side end face of the lifting plate 82. At this time, the second drive device drives the positioning pin 52 to move out of the clamping fixture 3. The worker releases the seal of the opening 31 of the clamping fixture 3, so that the battery cell can move to abut the lifting plate 82 under the action of its own gravity. Then the third drive mechanism 81 drives the lifting plate 82 to move in the direction away from the clamping fixture 3, so that the battery cell escapes from the clamping fixture 3. The battery cell that escapes from the clamping fixture 3 is pushed along the first direction (X) to the box entry platform 41 of the box entry mechanism 4. The pushing mechanism 42 pushes the neatly stacked battery cell group along the second direction (Y) into the chassis 44 to complete the stacking and boxing of the battery cells. The present application completes the automation of the stacking, transportation and boxing of the battery cells in the above manner, greatly reducing the consumption of human resources and the stacking cost. In addition, the automated boxing is easy to position and quick to operate, which improves the overall production efficiency of the battery cell module.

[0048] In some embodiments of the present invention, an oblique pushing mechanism 7 is arranged in the third direction (Z) of the flipping mechanism 6, and the oblique pushing mechanism 7 includes a fourth driving mechanism 71, and the fourth driving mechanism 71 abuts against the edge of the end face of the bracket 2 facing the oblique pushing mechanism 7. The fourth driving mechanism 71 can push the edge of the bracket 2 to move, so that the bracket 2 as a whole rotates with a straight line parallel to the first direction (X) as the axis. After the rotation, the opening 31 of the clamping fixture 3 is inclined toward the second direction (Y) and has a certain inclination. At this time, the worker can conveniently place the battery cell through the opening 31 in the accommodating cavity of the clamping fixture 3; the arrangement of the oblique pushing mechanism 7 is conducive to the feeding process of the battery cell in the clamping fixture 3, reduces the work intensity of the workers, and improves the work efficiency of stacking the battery cells into the box.

[0049] like Figure 3 As shown, in some embodiments of the present invention, the fourth driving mechanism 71 includes a hydraulic cylinder, which is tilted along the third direction (Z). The hydraulic rod 72 of the hydraulic cylinder extends toward the bracket 2 and is tilted. The end of the hydraulic rod 72 facing away from the hydraulic cylinder is fixedly connected to the horizontal end plate 22 of the bracket 2 close to the edge of the oblique pushing mechanism 7, so that the hydraulic rod 72 directly applies force to the horizontal end plate 22 of the bracket 2 under the drive of the hydraulic cylinder. When the hydraulic rod 72 extends out of the hydraulic cylinder, the horizontal end plate 22 is lifted up, driving the clamping fixture 3 to also tilt toward the second direction. At this time, the opening 31 is not horizontally set, but becomes tilted toward the second direction, so that the worker does not need to lift the battery cell higher and put it into the opening 31 along the third direction (Z), but can directly insert the battery cell horizontally into the clamping fixture 3 in the second direction (Y), which greatly reduces the workload of the workers in the process of placing the battery cell.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, a removable cover plate 32 is provided at the opening 31 of the clamping jig 3, and the cover plate 32 at least partially covers the opening 31 after the clamping jig 3 completes the clamping of the battery cell. It can be understood that the cover plate 32 can fully close the opening 31 or semi-close the opening 31, and the cover plate 32 can be manually installed and removed or machine installed and removed to achieve the working effect of preventing the battery cell from slipping and facilitating disassembly. Specifically, the edge of the clamping jig 3 near the opening 31 is provided with a fixing structure such as a screw or a buckle for easy disassembly, so that the cover plate 32 can be quickly removed when closing the opening 31 and unsealing the opening 31, which ensures the smooth opening and closing process of the opening 31 and further ensures the overall working efficiency of the device.

[0051] In some embodiments of the present invention, the first driving mechanism 61 includes a first rotating motor fixed on the vertical end plate 21 of the bracket 2, and the clamping fixture 3 is respectively located on both sides of the vertical end plate 21. The motor output shaft of the first rotating motor passes through the vertical end plate 21 of the bracket 2 along the second direction (Y), and the end of the motor output shaft is connected to the clamping fixture 3. The torque output by the first rotating motor can directly act on the clamping fixture 3 through the motor output shaft, so that the clamping fixture 3 can be accurately rotated under the control of the first rotating motor, so that the opening 31 of the clamping fixture 3 is rotated to face or back to the third direction (Z) for loading or unloading of battery cells.

[0052] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the second driving mechanism 51 includes a slide rail 53 extending along a second direction (Y), and the slide rail 53 is slidably connected to a fixed plate 54 extending along a third direction (Z). The fixed plate 54 and the slide rail 53 are arranged perpendicular to each other, and the second driving mechanism 51 can drive the fixed plate 54 to move along the second direction (Y) toward or away from the clamping fixture 3; a positioning plate 55 is fixed on the fixed plate 54, and a plurality of positioning pins 52 are arranged on the positioning plate 55. A plurality of positioning pin 52 holes corresponding to the number and positions of the positioning pins 52 are opened on the end surface of the clamping fixture 3 facing the positioning plate 55, so that the positioning pins 52 can be inserted into the interior of the clamping fixture 3 after approaching the clamping fixture 3, thereby fixing the battery cells and assisting in stacking the battery cells neatly.

[0053] In some embodiments of the present invention, a rotating disk 56 is provided inside the fixed plate 54, and the positioning disk 55 is fixed on the rotating disk 56 and can drive the rotating disk 56 to rotate. The rotating disk 56 gives the positioning disk 55 the degree of freedom in the torque direction of the clamping fixture 3, so that the positioning disk 55 can rotate with the rotation of the clamping fixture 3. During operation, when the flipping mechanism 6 drives the clamping fixture 3 to rotate, the positioning disk 55 rotates accordingly, so that the positioning pin 52 still keeps the battery cell fixed inside the clamping fixture 3. Furthermore, the rotating disk 56 is connected to a rotary motor 57. After the positioning pin 52 exits the clamping fixture 3, the rotary motor 57 drives the rotating disk 56 to reset, so that the positioning disk 55 and the positioning pin 52 return to the initial position, ready for the next battery cell stacking operation.

[0054] In some embodiments of the present invention, the third driving mechanism 81 includes a lifting cylinder, and the output shaft 83 of the lifting cylinder passes through the bracket 2 and is connected to the lifting plate 82. When the lifting cylinder outputs power, the output shaft 83 can move up and down in the third direction (Z), drive the lifting plate 82 to move in the third direction (Z) and complete the unloading process of the battery cell in the clamping fixture 3. The lifting mechanism 8 also includes a plurality of guide rods 84 arranged parallel to the output shaft 83 of the lifting cylinder. The guide rods 84 and the output shaft 83 of the lifting cylinder are both arranged vertically to the horizontal end plate 22 of the bracket 2. The bracket 2 is provided with a plurality of guide holes corresponding to the guide rods 84 and output holes corresponding to the output shaft 83 of the lifting cylinder. The diameters of the guide holes and the output holes are larger than the guide rods 84 and the output rods, so as to prevent the lifting cylinder from interfering with the horizontal end plate 22 during the lifting process.

[0055] In some embodiments of the present invention, a guide platform 43 is provided between the box entry platform 41 and the chassis 44, and two ends of the guide platform 43 are respectively connected to the box entry platform 41 and the chassis 44, and the guide platform 43 remains flush with the box entry platform 41 in the third direction (Z). The pushing mechanism 42 can move in the second direction (Y), and includes a driving mechanism and a pushing plate. The driving mechanism drives the pushing plate to move to the side of the battery cell of the box entry platform 41 facing away from the chassis 44, and then drives the pushing plate along the second direction (Y) to push the arranged battery cells along the guide platform 43 into the chassis 44, thereby completing the final box entry process of the battery cells.

[0056] The present invention also provides a method for stacking battery cells into a box, which adopts the battery cell stacking into a box mechanism of any one of the above embodiments, and comprises the following steps:

[0057] The flipping mechanism 6 rotates the clamping fixture 3 until the opening 31 faces upward along the third direction (Z);

[0058] The battery cell is placed in the box and the opening is closed 31;

[0059] The side push mechanism 5 pushes the positioning pin 52 in the second direction (Y) to insert into the clamping fixture 3, so that the battery cells are neatly arranged and stacked in the clamping fixture 3;

[0060] The turning mechanism 6 rotates the clamping fixture 3 until the opening 31 faces downward along the third direction (Z):

[0061] The third driving mechanism 81 drives the lifting plate 82 to abut against the clamping fixture 3 in the third direction (Z);

[0062] The side push mechanism 5 drives the positioning pin 52 to leave the clamping fixture 3, and then releases the seal of the opening 31, so that the battery cell moves through the opening 31 to the lifting plate 82 under the action of gravity;

[0063] The third driving mechanism 81 drives the lifting plate 82 to move downward along the third direction (Z) until the battery cell leaves the clamping fixture 3;

[0064] Push the battery cell to move along the first direction (X) to the box entry platform 41;

[0065] The pushing mechanism 42 pushes the battery cell along the second direction (Y) into the case 44 to complete the packaging.

[0066] The stacking method of the present application realizes the automation of stacking, transporting and packing of battery cells, greatly reduces the consumption of human resources, reduces the stacking cost, and the automated boxing, easy positioning, and quick operation improves the overall production efficiency of the battery cell module.

[0067] In some embodiments of the present invention, after the flipping mechanism 6 rotates the clamping jig 3 until the opening 31 is facing upward along the third direction (Z), the oblique pushing mechanism 7 pushes the clamping jig 3 to tilt toward the second direction, so that the opening 31 also rotates toward the second direction, making it easier for workers to insert the battery cells through the opening 31.

[0068] The working process of the present invention is as follows: a clamping fixture 3 is arranged on the frame 1, a lifting mechanism 8 is arranged on one side of the third direction (Z) of the clamping fixture 3, a box-entering mechanism 4 is arranged on one side of the first direction (X) of the clamping fixture 3, and a side pushing mechanism 5 and a flipping mechanism 6 are respectively arranged on both sides of the second direction (Y) of the clamping fixture 3; when working, the oblique pushing mechanism 7 first pushes the clamping fixture 3 until the opening 31 is inclined toward the second direction (Y), and then the battery cell is placed in the clamping fixture 3 through the opening 31, and the opening 31 of the clamping fixture 3 is closed, and the oblique pushing mechanism 7 retreats to make the opening 31 face the third direction (Z), and then the second driving mechanism 51 of the side pushing mechanism 5 inserts the positioning pin 52 into the clamping fixture 3 in the second direction (Y), so that the battery cells in the clamping fixture 3 are stacked neatly. The first driving mechanism 61 of the flipping mechanism 6 rotates the clamping fixture 3 until the opening 31 is aligned with the lifting plate 82 of the lifting mechanism 8. The third driving mechanism 81 of the lifting mechanism 8 drives the lifting plate 82 to move toward the clamping fixture 3 in the third direction (Z) until it abuts against the clamping fixture 3. At this time, the seal of the opening 31 of the clamping fixture 3 is released, so that the battery cell can move to abut against the lifting plate 82 under the action of its own gravity. At this time, the third driving mechanism 81 drives the lifting plate 82 to move in the back direction of the clamping fixture 3, so that the battery cell is out of the clamping fixture 3. The battery cell that has been separated from the clamping fixture 3 is pushed along the first direction (X) to the boxing platform 41 of the boxing mechanism 4, and the pushing mechanism 42 pushes the neatly stacked battery cell group along the second direction (Y) into the chassis 44, completing the stacking and boxing of the battery cells.

[0069] In summary, the embodiments of the present invention provide a battery cell stacking and boxing mechanism and a battery cell stacking and boxing method, which realize the automation of battery cell stacking, transportation and boxing, greatly reduce the consumption of human resources, reduce the stacking cost, and the automated boxing, easy positioning, and quick operation improve the overall production efficiency of the battery cell module.

[0070] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
