[0002] In the automatic process of multi-section battery, the battery cells need to be stacked in order and then placed in a case. At present, the stacking and module case entering process of battery cells is basically achieved by manual handling or crane. In the process of manual operation, a separate multi-station operation is generally required, which wastes a large amount of human resources. Moreover, the module case entering positioning is difficult, the operation is slow, and the production efficiency of the battery cell module is also reduced. SUMMARY

[0003] The present application aims to provide a battery cell stacking and case entering mechanism and method, which realizes the automation of battery cell stacking, transfer and case entering, greatly reduces the consumption of human resources, reduces the stacking cost, and improves the overall production efficiency of the battery cell module.

[0004] In order to achieve the above-mentioned purpose, the present application provides a battery cell stacking and case entering mechanism, which comprises:

[0008] A jacking mechanism is provided, which comprises a third driving mechanism and a jacking plate, and the end face of the jacking plate is arranged towards the clamping jig, and the third driving mechanism can drive the jacking plate to approach the opening of the clamping jig after the clamping jig rotates;

[0009] A case entering mechanism is provided, which comprises a case entering platform and a pushing mechanism, the case entering platform is arranged on one side of the rack, and the pushing mechanism is used to push the arranged battery cells into the case.

[0010] Compared with the prior art, the beneficial effects of the battery cell stacking and boxing mechanism of this invention are as follows: A clamping fixture is provided on the frame, a lifting mechanism is provided at the bottom of the clamping fixture, a boxing mechanism is provided on one side of the clamping fixture, and a side-pushing mechanism and a flipping mechanism are respectively provided on both sides of the clamping fixture; during operation, the battery cells are placed into the clamping fixture through the opening, the opening of the clamping fixture is closed, and then the second drive mechanism of the side-pushing mechanism inserts the positioning pin into the clamping fixture, making the battery cells stacked neatly in the clamping fixture. At this time, the first drive mechanism of the flipping mechanism rotates the clamping fixture until the opening is aligned with the lifting plate of the lifting mechanism. The third drive mechanism of the lifting mechanism drives the lifting plate to move vertically toward the clamping fixture until it abuts against the fixture. At this time, the second drive mechanism drives the positioning pin to move out of the clamping fixture and releases the seal of the opening of the clamping fixture, allowing the battery cell to move under its own weight to abut the lifting plate. Then, the third drive mechanism drives the lifting plate to move away from the clamping fixture, causing the battery cell to detach from the clamping fixture. The battery cell detached from the clamping fixture is pushed horizontally by manual or mechanical means to the boxing platform of the boxing mechanism. The pushing mechanism then pushes the neatly stacked battery cell group into the chassis, completing the stacking and boxing of the battery cells. This application automates the stacking, transfer, and boxing of battery cells, greatly reducing the consumption of human resources, lowering stacking costs, and improving the overall production efficiency of battery cell modules through automated boxing, simple positioning, and quick operation.

[0013] In the battery cell stacking mechanism of this invention, the clamping fixture has an opening, and a detachable cover plate is provided at the opening. After the clamping fixture completes the battery cell clamping, the cover plate at least partially covers the opening.

[0018] In the battery cell stacking and boxing mechanism of this invention, a guide platform is provided between the boxing platform and the chassis. The guide platform is flush with the boxing platform in the vertical direction. The pushing mechanism pushes the arranged battery cells into the chassis along the guide platform.

[0019] The present invention also provides a method for stacking battery cells into a box, which employs the battery cell stacking mechanism described in any of the above embodiments, and includes the following steps:

[0026] The third drive mechanism drives the lifting plate to move downward along the third direction until the battery cell leaves the clamping fixture;

[0027] The battery cell is moved to the box-in platform;

[0028] The pushing mechanism pushes the battery cell into the chassis to complete the packaging.

[0029] Compared with the prior art, the beneficial effects of the battery cell stacking and boxing mechanism of this invention are as follows: During operation, the battery cells are placed in the clamping fixture through the opening, the opening of the clamping fixture is closed, and then the second drive mechanism of the side pushing mechanism inserts the positioning pin into the clamping fixture to make the battery cells stacked neatly in the clamping fixture. At this time, the first drive mechanism of the flipping mechanism rotates the clamping fixture until the opening is aligned with the lifting plate of the lifting mechanism. The third drive mechanism of the lifting mechanism drives the lifting plate to move towards the clamping fixture until it abuts against the clamping fixture.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0040] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0041] like Figure 1 and Figure 2As shown, a preferred embodiment of the present invention provides a battery cell stacking mechanism, which includes a frame 1. The frame 1 has intersecting first direction (X), second direction (Y) and third direction (Z), 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] The frame 1 is equipped with a support 2, which has an L-shaped structure and includes a vertical end plate 21 extending in a third direction and a horizontal end plate 22 extending in a second direction. The support 2 is equipped with a clamping fixture 3 for accommodating the battery cells. The clamping fixture 3 is a standard cuboid structure with an internal accommodating cavity, so that the battery cells are stacked neatly in the clamping fixture 3. A lifting mechanism 8 is provided on one side of the clamping fixture 3 in the third direction (Z), an infeeding mechanism 4 is provided on one side of the clamping fixture 3 in the first direction (X), and a side pushing mechanism 5 and a flipping mechanism 6 are respectively provided on both sides of the clamping fixture 3 in the second direction (Y). The clamping fixture 3 has an opening 31 for the entry and exit of the battery cells. The opening 31 can be closed during operation to prevent the battery cells from sliding out directly through the opening 31 during the flipping process.

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

[0044] The side-pushing mechanism 5 is located on 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 is slidably located on 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, it keeps the battery cell fixed in the clamping fixture 3 in the second direction (Y) and the first direction (X). During the rotation, it ensures that the battery cells are stacked neatly and also ensures that the clamping fixture 3 will not be displaced in the second direction (Y).

[0045] The lifting mechanism 8 is located on the third direction (Z) of the bracket 2. The lifting mechanism 8 includes a third drive mechanism 81 and a lifting plate 82. The lifting plate 82 is arranged parallel to the horizontal end plate 22 of the bracket 2. The lifting plate 82 is located 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 faces the clamping fixture 3. The third drive 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). After the clamping fixture 3 is rotated and the opening 31 is unsealed, the battery cell can fall onto the lifting plate 82 under its own gravity and can be smoothly disengaged from the clamping fixture 3 as the lifting plate 82 moves in the third direction (Z).

[0046] The boxing mechanism 4 is located on the first direction (X) of the bracket 2. The boxing mechanism 4 includes a boxing platform 41 and a pushing mechanism 42. The height of the boxing platform 41 is flush with the height of the lifting plate 82 after it is lowered. After the lifting plate 82 drives the battery cell to move down, the battery cell can be moved onto the boxing platform 41 by manual or mechanical pushing by the worker. The boxing platform 41 is provided with a housing 44 for accommodating the battery cell assembly on one side of the second direction (Y). The pushing mechanism 42 can move in the second direction (Y) to push the neatly stacked battery cells on the boxing platform 41 directly into the housing 44 to complete the boxing of the battery cells.

[0047] In the embodiments of this application, multiple battery cells are first placed into the clamping fixture 3 through the opening 31. The worker manually or mechanically closes the opening 31 of the clamping fixture 3. Then, the second drive 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 and kept fixed. At this time, the first drive 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 drive mechanism 81 of the lifting mechanism 8 drives the lifting plate 82 to move towards the clamping fixture 3 in the third direction (Z) until it abuts against the clamping fixture 3. The clamping fixture 3 faces one 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, allowing the battery cell to move under its own weight to abut the lifting plate 82. Then, the third drive mechanism 81 drives the lifting plate 82 to move away from the clamping fixture 3, causing the battery cell to detach from the clamping fixture 3. The battery cell detached from the clamping fixture 3 is pushed along the first direction (X) to the boxing platform 41 of the boxing mechanism 4. 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. This application automates the stacking, transfer and boxing of battery cells through the above method, greatly reducing the consumption of human resources, reducing stacking costs, and improving the overall production efficiency of battery cell modules through automated boxing, simple positioning and quick operation.

[0048] In some embodiments of the present invention, a slanting push mechanism 7 is provided on the third direction (Z) of the flipping mechanism 6. The slanting push mechanism 7 includes a fourth driving mechanism 71. The fourth driving mechanism 71 abuts against the edge of the end face of the bracket 2 facing the slanting push 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 about a straight line parallel to the first direction (X) as the axis. After rotation, the opening 31 of the clamping fixture 3 is inclined towards the second direction (Y) with a certain inclination. At this time, the worker can conveniently place the battery cell into the receiving cavity of the clamping fixture 3 through the opening 31. The slanting push mechanism 7 is beneficial to the feeding process of the battery cell in the clamping fixture 3, reduces the labor intensity of the worker, and improves the efficiency of stacking the battery cell into the box.

[0049] like Figure 3 As shown, in some embodiments of the present invention, the fourth drive mechanism 71 includes a hydraulic cylinder, which is inclined along the third direction (Z). The hydraulic rod 72 of the hydraulic cylinder extends toward the bracket 2 and is inclined. The end of the hydraulic rod 72 facing away from the hydraulic cylinder is fixedly connected to the edge of the horizontal end plate 22 of the bracket 2 near the edge of the inclined push 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, which drives the clamping fixture 3 to also tilt toward the second direction. At this time, the opening 31 is not horizontal, but tilts 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 worker in placing the battery cell.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, a detachable cover plate 32 is provided at the opening 31 of the clamping fixture 3. After the clamping fixture 3 completes the cell clamping, the cover plate 32 at least partially covers the opening 31. It is understood that the cover plate 32 can fully close the opening 31 or partially close the opening 31. The cover plate 32 can be installed and removed manually or by machine, as long as it achieves the effect of preventing the cell from slipping and facilitating disassembly. Specifically, the clamping fixture 3 is provided with a fixing structure such as screws or buckles near the edge of the opening 31 for easy disassembly, so that the cover plate 32 can be quickly disassembled when closing and unsealing the opening 31, ensuring the smooth opening and closing process of the opening 31 and further ensuring the overall working efficiency of the device.

[0051] In some embodiments of the present invention, the first drive mechanism 61 includes a first rotary motor fixed on the vertical end plate 21 of the bracket 2, and the clamping fixture 3 is located on both sides of the vertical end plate 21. The motor output shaft of the first rotary motor passes through the vertical end plate 21 of the bracket 2 along the second direction (Y). The end of the motor output shaft is connected to the clamping fixture 3. The torque output by the first rotary motor can be directly applied to the clamping fixture 3 through the motor output shaft, so that the clamping fixture 3 can rotate accurately under the control of the first rotary motor, so that the opening 31 of the clamping fixture 3 rotates to face or away from the third direction (Z) for feeding or unloading of the 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 the second direction (Y), and a fixed plate 54 extending along the third direction (Z) is slidably connected to the slide rail 53. The fixed plate 54 and the slide rail 53 are arranged perpendicular to each other. The second driving mechanism 51 can drive the fixed plate 54 to move towards or away from the clamping fixture 3 along the second direction (Y). A positioning disk 55 is fixed on the fixed plate 54, and a plurality of positioning pins 52 are provided on the positioning disk 55. A plurality of positioning pin 52 holes corresponding to the number and position of the positioning pins 52 are opened on the end face of the clamping fixture 3 facing the positioning disk 55, so that the positioning pins 52 can be inserted into the interior of the clamping fixture 3 after approaching the clamping fixture 3, fixing the battery cell and assisting the battery cell to be stacked neatly.

[0053] In some embodiments of the present invention, a rotating disk 56 is provided inside the fixing plate 54. The positioning disk 55 is fixed on the rotating disk 56 and can drive the rotating disk 56 to rotate. The rotating disk 56 provides the positioning disk 55 with 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 remains fixed inside the clamping fixture 3. Further, 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 their initial positions, ready for the next stacking operation of the battery cells.

[0054] In some embodiments of the present invention, the third drive mechanism 81 includes a lifting cylinder. 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), driving 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 multiple guide rods 84 arranged parallel to the output shaft 83 of the lifting cylinder. Both the guide rods 84 and the output shaft 83 of the lifting cylinder are arranged perpendicular to the horizontal end plate 22 of the bracket 2. The bracket 2 has multiple 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 output holes are larger than the guide rods 84 and the output rods, 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 loading platform 41 and the chassis 44. The two ends of the guide platform 43 are respectively connected to the loading platform 41 and the chassis 44. The guide platform 43 is flush with the loading platform 41 in the third direction (Z). The pushing mechanism 42 can move in the second direction (Y). It includes a driving mechanism and a push plate. The driving mechanism drives the push plate to move to the side of the loading platform 41 where the battery cell is facing away from the chassis 44. Then, the push plate drives the arranged battery cell to enter the chassis 44 along the guide platform 43 in the second direction (Y), thus completing the final loading process of the battery cell.

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

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

[0058] The battery cells are placed in the box and the opening is sealed 31;

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

[0060] The flipping mechanism 6 rotates the clamping fixture 3 to the opening 31, with the fixture facing downwards in the third direction (Z).

[0061] The third drive 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, allowing the battery cell to move through the opening 31 to the lifting plate 82 under the action of gravity.

[0063] The third drive 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] The battery cell is moved along the first direction (X) to the box-in platform 41;

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

[0066] The stacking method of this application automates the stacking, transportation and packaging of battery cells, greatly reducing the consumption of human resources and the stacking cost. Moreover, the automated packaging, simple positioning and quick operation improve the overall production efficiency of battery cell modules.

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

[0068] The working process of this invention is as follows: A clamping fixture 3 is provided on the frame 1. A lifting mechanism 8 is provided on one side of the clamping fixture 3 in the third direction (Z). An infeeding mechanism 4 is provided on one side of the clamping fixture 3 in the first direction (X). A side pushing mechanism 5 and a flipping mechanism 6 are respectively provided on both sides of the clamping fixture 3 in the second direction (Y). During operation, the oblique pushing mechanism 7 first pushes the clamping fixture 3 until the opening 31 is tilted towards the second direction (Y). Then, the battery cell is placed into the clamping fixture 3 through the opening 31. The opening 31 of the clamping fixture 3 is closed. The oblique pushing mechanism 7 retracts so that the opening 31 is tilted towards the third direction (Z). 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 drive 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 drive 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 its own gravity. At this time, the third drive mechanism 81 drives the lifting plate 82 to move away from the clamping fixture 3, so that the battery cell is removed from the clamping fixture 3. The battery cell that is removed from the clamping fixture 3 is pushed along the first direction (X) to the boxing platform 41 of the boxing mechanism 4. The pushing mechanism 42 pushes the neatly stacked battery cell group into the chassis 44 along the second direction (Y), 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 realizes the automation of battery cell stacking, transfer and boxing, greatly reduces the consumption of human resources, reduces stacking costs, and the automated boxing, positioning is simple and operation is quick, thereby improving the overall production efficiency of battery cell modules.

[0070] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
