[0084] One embodiment of the present invention provides a battery cell stacking device 1, comprising:

[0085] Battery cell stacking turntable 11;

[0086] A stacking rack 12, at least one of the stacking racks 12 is provided on the cell stacking turntable 11, and one side of the stacking rack 12 is a bevel;

[0087] a stacking support assembly 13, wherein the stacking support assembly 13 is arranged on the oblique edge;

[0088] a fixed support 14, the fixed support 14 being mounted on the top of the bevel;

[0089] The single-cell centering mechanism 16 , at least one pair of the single-cell centering mechanisms 16 are symmetrically installed on the hypotenuse, and the single-cell centering mechanism 16 is close to the fixed support 14 .

[0090] In this embodiment, the fixed support 14 and the stacking support assembly 13 are located on the same straight line to maintain the pressure of the battery cells. The battery cell stacking turntable 11 is controlled by a high-torque servo motor and a reducer to drive the stacking rack 12 above it to perform a 180-degree precise reciprocating rotation. The stacking rack 12 is installed on the battery cell stacking turntable 11. The optimal inclination angle of the upper bevel of the stacking rack 12 is 60 degrees. By setting the upper bevel of the stacking rack 12 to 60 degrees, the stacking support can better support the battery cells and cooperate with the fixed support 14 to maintain the pressure of the equipment and load new battery cells.

[0091] The stacking support assembly 13 is driven by the driving mechanism 135. Each time a battery cell is loaded, the stacking support moves along the oblique edge under the action of the driving mechanism 135 to ensure the stable stacking of the battery cells. The stacking support assembly 13 ensures the accuracy and stability of the battery cell stacking. The single battery cell centering mechanism 16 ensures that the battery cell is aligned with the stacked battery cells during the battery cell loading process, ensuring the stability of the battery cell loading and the neatness between the battery cells. After each battery cell is loaded, the stacking support assembly 13 moves once and cooperates with the fixed support 14 to apply pressure to the stacked battery cells to achieve pressure maintenance between the battery cells and ensure that the battery cells are completely bonded by glue.

[0092] The present invention ensures that the battery cell components can be loaded stably through the arrangement of the stacking rack 12, the stacking support and the single battery cell centering mechanism 16. The battery cell is protected and pressed after loading through the stacking support assembly 13 and the first spring mechanism on the fixed support 14. The structure is simple and the degree of automation is improved.

[0093] In one embodiment, the stack support assembly 13 includes:

[0094] The driving mechanism 135 includes a driving motor 1351 and a guide rail assembly 1352 . The driving motor 1351 drives the guide rail assembly 1352 .

[0095] In this embodiment, the guide rail assembly 1352 is driven to rotate by the driving motor 1351 to adjust the slide assembly 131, so that the stacking support moves downward along with the upper part of the battery cell assembly, so as to achieve cooperation between the slide assembly 131 and the fixed support and maintain the pressure of the battery cell.

[0096] In one embodiment, the stack support assembly 13 further includes:

[0097] Support components, including a slide assembly 131, a support plate 133, and a pressing drive cylinder 132;

[0098] The slide assembly 131 is mounted on the guide rail assembly 1352;

[0099] The support plate 133 is mounted on the slide assembly 131 , and a pressing plate 134 is movably mounted on the support plate 133 ;

[0100] The pressing drive cylinder 132 is installed on the support plate 133 , and the pressing drive cylinder 132 clamps the pressing plate 134 .

[0101] In this embodiment, the pressing plate 134 is driven by the pressing drive cylinder 132, and the slide assembly 131 is connected to the bevel sliding through the linear guide rail, which is convenient for moving the stacking support, so that the end plate and the insulating cover are fitted on the support plate 133, and the pressing plate 134 body is driven by the top pressing drive cylinder 132 to press the end plate and the insulating cover on the support plate 133, and make the insulating cover fit the battery cell assembly. It can be understood that by setting the pressing plate 134 body into an L shape, the end plate and the insulating cover can be better fixed, which is convenient for the final molding of the battery cell module. After the battery cell centering mechanism 16 presses and centers the battery cells and their components, the stacked battery cells and slide assembly 131 move upward to fit the upper battery cells. The single battery cell centering mechanism 16 opens, and the slide assembly 131 continues to move upward to the first elastic mechanism, thereby effectively adhering the glue or tape between the stacked battery cells and their components, making them more firmly adhered, and completing the pressure-maintaining movement of the battery cells. The above actions are repeated in sequence to stack the battery cells and their components into modules, which is convenient for the next workstation to pick up and process. A suction cup is also provided on the clamping plate 134 to ensure that the parts are stable and do not fall off when the upper and lower end plates are moved for the first time.

[0102] In one embodiment, a first elastic mechanism is installed on the fixed support 14 , and the first elastic mechanism cooperates with the slide assembly 131 to press the battery core.

[0103] In this embodiment, the first elastic mechanism provided on the fixing support 14 facilitates the pressure-maintaining and compacting of the cell modules after the cell assemblies are stacked, so that the cell modules are fixed.

[0104] In one embodiment, the single cell centering mechanism 16 includes:

[0105] A movable bracket 161, wherein the movable bracket 161 is installed on the bevel;

[0106] A pressing component is mounted on the movable bracket 161 and includes a pressing block 162, a first telescopic cylinder 163, and a movable block 164. The pressing block 162 is mounted on the movable block 164, and the movable block 164 is driven by the first telescopic cylinder 163.

[0107] A first pressing block 165 , which is mounted on the movable bracket 161 ;

[0108] The second pressing block 166 is also installed on the movable bracket 161 and is located on one side of the first pressing block.

[0109] In this embodiment, the driving assembly includes a screw rod, and the movable bracket 161 is pre-adjusted by rotating the screw rod. The first telescopic cylinder 163 is installed on the movable bracket 161. The first telescopic cylinder 163 drives the movable block 164 to move, and the movable block 164 is slidably connected to the movable bracket 161. The optimal shape of the top pressing block 162 is L-shaped. Through the setting of the top pressing block 162, the battery cell on the upper part of the battery cell gripper 2 is pressed to ensure that the battery cell fits the bevel on the stacking rack 12, thereby ensuring the stability of the battery cell when stacking;

[0110] The second clamping block 166 is movably connected to the movable bracket 161. When the battery cell gripper 2 puts the new battery cell onto the stacking rack 12, the first clamping block 165 clamps the new battery cell, and the second clamping block 166 clamps the stacked battery cell, and straightens the battery cell to ensure that the battery cell is aligned with the stacked battery cell. After alignment, the slide assembly 131 moves to fit the stacked battery cell with the new battery cell. At this time, the first clamping block 165 moves away, and the second clamping block 166 moves together with the stacked battery cell. After the slide assembly 131 and the fixed support maintain pressure on the new battery cell and the stacked battery cell, the second clamping block 166 moves away, so that the new battery cell is adhered to the stacked battery cell.

[0111] In one embodiment, the single cell centering mechanism 16 further includes:

[0112] The telescopic component includes a second telescopic cylinder 167 and a movable pressing plate 168 , and the second telescopic cylinder 167 drives the movable pressing plate 168 .

[0113] In this embodiment, when the battery cell gripper 2 loads the new battery cell, the movable pressure plate 168 is extended under the drive of the second telescopic cylinder 167 to block the new battery cell from the stacked battery cells. At the same time, the slide assembly 131 cooperates with the movable pressure plate 168 to ensure the stability of the adhesion of the stacked battery cells. When the new battery cell is straightened, the second telescopic cylinder 167 drives the movable pressure plate 168 to retract, and the new battery cell contacts the stacked battery cell. The slide assembly 131 cooperates with the fixed support to maintain the pressure on the battery cell.

[0114] In one embodiment, the battery cell stacking device 1 further includes:

[0115] A centering mechanism 15 is installed on the oblique side of the stacking rack 12 .

[0116] In this embodiment, after the battery cells are stacked to form a battery cell module, when the battery cell stacking turntable 11 rotates, the centering mechanism 15 presses the module to ensure that the battery cell module does not deviate.

[0117] In one embodiment, the centering mechanism 15 includes:

[0118] A movable plate 151 is slidably mounted on the bevel and is provided with an adjustment mechanism 152;

[0119] a centering drive cylinder 153 , wherein the centering drive cylinder 153 is mounted on the movable plate 151 and drives the adjustment mechanism 152 ;

[0120] A centering plate 154 is connected to the centering drive cylinder 153 , and the centering plate 154 moves toward or away from the stacking support assembly 13 .

[0121] In this embodiment, the movable plate 151 is slidably mounted on the stacking rack 12 via a bracket and a guide rail. The movable plate 151 is provided with an adjustment mechanism 152 for adjusting the movable plate 151. The centering drive cylinder 153 is mounted on the movable plate 151, and the output shaft of the centering drive cylinder 153 passes through the movable plate 151. The centering plate 154 is fixedly connected to the output shaft of the centering drive cylinder 153. A linear guide rail is symmetrically fixedly connected to the side of the centering plate 154 facing the movable plate 151, and the linear guide rail passes through the movable plate 151.

[0122] The battery cell module is protected by driving the centering plate 154 through the driving cylinder. When the battery cell stacking turntable 11 rotates, the centering mechanism 15 presses the module to ensure that the battery cell module will not shift. The centering plate 154 is symmetrically fixedly connected to the two sides of the movable plate 151 with linear guide rails to limit the movement trajectory of the centering plate 154. The movable plate 151 is pre-adjusted by the adjustment mechanism 152 according to the maximum activity value of the centering drive cylinder 153, and the battery cell module is straightened from the side to ensure the stability of the battery cell module when the battery cell stacking turntable 11 rotates.

[0123] In one embodiment, the adjustment mechanism 152 includes:

[0124] A screw rod is rotatably mounted on the stacking frame 12 and is connected to the movable plate 151 .

[0125] In this embodiment, one end of the screw rod is connected to a hand wheel, and the movable plate 151 is pre-adjusted through the adjustment mechanism 152 according to the maximum movable value of the centering drive cylinder 153.

[0132] In this embodiment, one of the floating mechanisms 23 is driven to move by a rodless cylinder, changing the position between the two floating mechanisms 23, and then changing the position between the two grippers, so as to facilitate the distance change between the grippers. After the distance change, the battery cell and the end plate grippers are clamped and moved to the battery cell assembly stacking position. The gripper changes distance while moving. After moving to the upper position of the stacking rack 12, the top is pressed down, the top of the stacking table is pressed down and centered, and the gripper moves to the upper position and changes distance during the movement. The battery cell module is positioned in the height direction by the setting of the top pressure. The battery cell or end plate grippers are set, and the battery cell or end plate is taken. By setting the floating mechanism 23, when loading the battery cell assembly, the top pressure and the single battery cell centering mechanism 16 on the battery cell stacking device 1 are cooperated to achieve the final battery cell positioning effect, thereby ensuring the accuracy of the battery cell assembly when loading.
