The described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application.

[0036] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0037] Example 1

[0038] Reference Figs. 1-2 The device for folding double battery cells into a middle plate of a BMU provided in the present embodiment comprises a middle plate transfer mechanism 1, a BMU plate positioning mechanism 2, a double battery cell folding mechanism 3 and a middle plate pressure maintaining mechanism 4. The BMU plate positioning mechanism 2 is arranged on the working path of the middle plate transfer mechanism 1, the double battery cell folding mechanism 3 is arranged on the outer periphery of the BMU plate positioning mechanism 2, and the middle plate pressure maintaining mechanism 4 is arranged above the BMU plate positioning mechanism 2.

[0039] The middle plate conveying mechanism 1 is used to convey the middle plate from the previous work station to the BMU plate positioning mechanism 2 for pasting the middle plate and the BMU plate. The middle plate conveying mechanism 1 comprises a first driving unit 11 and an adsorption unit 12 drivingly connected with the first driving unit 11. The adsorption unit 12 comprises a plurality of suction cups, preferably four, which can be adsorbed to the four corner positions of the middle plate, thereby achieving a more stable fixing effect.

[0040] In the embodiment, the middle plate comprises a middle plate body, a first pasting part and a second pasting part, the first pasting part and the second pasting part are arranged at the same end of the middle plate body and are located on both sides of the middle plate body respectively, and the first pasting part and the second pasting part are perpendicular to the middle plate body. The adsorption unit 12 is used to adsorb and fix the middle plate body.

[0041] It should be noted that the two electric cores loaded onto the double electric core folding mechanism 3 have been welded with the BMU plate. After the assembly of the double electric cores and the BMU plate is completed, the two electric cores are located on the double electric core folding mechanism 3, and the BMU plate is located on the BMU plate positioning mechanism 2. During operation, when the middle plate conveying mechanism 1 conveys the middle plate to above the BMU plate positioning mechanism 2, the middle plate body is in a vertical state, and the first pasting part and the second pasting part are in a horizontal state and correspond to the position of the BMU plate. Then, the first pasting part and the second pasting part are pressed by the middle plate pressure maintaining mechanism 4, so as to be attached to the surface of the BMU plate. Then, the double electric core folding mechanism 3 folds the two electric cores and attaches them to the opposite sides of the middle plate body, thereby completing the operation of folding the double electric cores to the BMU middle plate. It should be noted that the adsorption unit 12 still maintains the adsorption and fixation of the middle plate during the middle plate pressure maintaining process, so that the position of the middle plate on the BMU plate remains fixed and is not easy to shift, thereby making the attachment position of the middle plate more accurate and fixed, and improving the production quality of the battery product and the consistency of the product.

[0042] In some embodiments, the first driving unit 11 can be a driving module or a mechanical arm, etc. As one of the embodiments, the first driving unit 11 comprises a first driving assembly 111 for driving the adsorption unit 12 to rotate, a second driving assembly 112 for driving the adsorption unit 12 to move up and down, and a third driving assembly 113 for driving the adsorption unit 12 to move horizontally. Specifically, the adsorption unit 12 is connected with the driving end of the first driving assembly 111, the driving end of the second driving assembly 112 is connected with the fixed end of the first driving assembly 111, and the driving end of the third driving assembly 113 is connected with the fixed end of the second driving assembly 112. The first driving assembly 111, the second driving assembly 112 and the third driving assembly 113 can all be driving motors.

[0043] The device for folding the double battery cell to the middle plate of the BMU in the embodiment can realize the attachment of the middle plate and the BMU plate through the cooperation of the adsorption unit and the middle plate pressure maintaining mechanism. During the pressure maintaining process of the middle plate by the middle plate pressure maintaining mechanism, the adsorption unit still maintains the adsorption and fixation of the middle plate, so that the attachment position of the middle plate on the BMU plate is more accurate and fixed, thereby improving the production quality of the product and being beneficial to improving the consistency of the product.

[0044] Embodiment 2

[0045] As a further optimization of embodiment 1, reference is made to Fig. 3 and 4 The middle plate pressure maintaining mechanism 4 comprises a pressure maintaining unit 41, a second driving unit 42 for driving the pressure maintaining unit 41 to move horizontally, and a third driving unit 43 for driving the pressure maintaining unit 41 and the second driving unit 42 to move up and down. In the embodiment, the second driving unit 42 and the third driving unit 43 are both driving air cylinders.

[0046] In the embodiment, the pressure maintaining unit 41 comprises a first pressure maintaining plate 411 and a second pressure maintaining plate 412, both of which are connected with the driving end of the second driving unit 42, and the first pressure maintaining plate 411 and the second pressure maintaining plate 412 are arranged in parallel, and the first pressure maintaining plate 411 and the second pressure maintaining plate 412 are respectively used for maintaining the first adhesive part and the second adhesive part of the middle plate. By arranging the first pressure maintaining plate 411 and the second pressure maintaining plate 412 to maintain the first adhesive part and the second adhesive part respectively, the pressure maintaining effect is better, which can ensure the firmness of the adhesion between the middle plate and the BMU plate and improve the product quality.

[0047] During the pressure maintaining process of the middle plate, the end of the first pressure maintaining plate 411 and the end of the second pressure maintaining plate 412 respectively abut against the first adhesive part and the second adhesive part, the adsorption unit 12 is adsorbed on the side surface of the middle plate body corresponding to the position of the first adhesive part, the first pressure maintaining plate 411 passes through the gap between the suction cups and abuts against the first adhesive part, and the adsorption unit 12 cooperates with the pressure maintaining unit 41 without interfering with each other, which can ensure the orderly progress of the middle plate pressure maintaining operation.

[0048] In some embodiments, the device for folding the double battery cell to the middle plate of the BMU further comprises a middle plate fixing mechanism 5 for fixing the middle plate during the folding operation of the double battery cell. The middle plate fixing mechanism 5 is connected with the driving end of the second driving unit 42 and located on one side of the pressure maintaining unit 41. Through the driving of the second driving unit 42, the position switching of the pressure maintaining unit 41 and the middle plate fixing mechanism 5 can be realized to realize the continuity of the middle plate pressure maintaining operation and the folding operation of the double battery cell, thereby improving the production efficiency.

[0049] The middle plate fixing mechanism 5 comprises a clamping unit 51 and a fourth driving unit 52 for driving the clamping unit 51 to move up and down, and the clamping unit 51 is used for clamping the upper end of the middle plate body. After the pressure maintaining unit 41 completes the middle plate pressure maintaining operation, the clamping unit 51 reaches above the middle plate under the driving of the second driving unit 42, and then the clamping unit 51 moves downward under the driving of the fourth driving unit 52 and clamps the upper end of the middle plate body, while the adsorption unit 12 stops adsorbing and resets. In this way, the position of the middle plate is fixed, ensuring that the middle plate does not move during the subsequent double-cell folding operation, improving production quality, and the clamping unit 51 does not interfere with the double-cell folding operation, ensuring the orderly performance of the double-cell folding operation. In this embodiment, the fourth driving unit 52 is a driving air cylinder.

[0050] As a further optimization, the middle plate fixing mechanism 5 further comprises a pressing unit 53 connected with the driving end of the fourth driving unit 52, and the pressing unit 53 is used for pressing the top of the middle plate. In this embodiment, the clamping unit 51 comprises a first clamping plate and a second clamping plate, and the pressing unit 53 comprises a pressing block located between the first clamping plate and the second clamping plate. Through the cooperation of the clamping unit 51 and the pressing unit 53, the upper end of the middle plate body can be stably fixed, so that the first and second adhesive parts of the middle plate are tightly attached to the surface of the BMU plate, ensuring that the position of the middle plate remains fixed during the double-cell folding operation, so as to ensure the accuracy and stability of the relative position between the middle plate and the cell, further improving the product quality. In some embodiments, the widths of the first clamping plate, the second clamping plate and the pressing block are greater than the width of the middle plate body, thereby achieving a more stable fixing effect.

[0053] In some embodiments, the fifth driving unit 22 can be a micro module. Through the driving of the fifth driving unit 22, the position of the BMU plate positioning platform 21 in the vertical direction can be adjusted, so as to adjust the reference distance between the middle plate and the cell during the double-cell folding process, and ensure the accuracy of the double-cell folding and the accuracy of the attachment position between the cell and the middle plate.

[0054] The double-battery-cell folding mechanism 3 comprises a first fixed platform 31, a second fixed platform 32, and a sixth driving unit 33. The first fixed platform 31 and the second fixed platform 32 are respectively located on opposite sides of the BMU plate positioning platform 21.

Under the driving of the sixth driving unit 33, the first fixed platform 31 and the second fixed platform 32 fold towards each other and are each folded from a horizontal state to a vertical state, so as to simultaneously adhere the battery cells on the first fixed platform 31 and the second fixed platform 32 to opposite sides of the middle plate.

[0056] In some embodiments, the first fixed platform 31 is provided with a suction assembly 311 and a clamping assembly 312. The suction assembly 311 is arranged at the bottom of the first fixed platform 31, and the clamping assembly 312 is arranged at one side of the suction assembly 311. The suction assembly 311 comprises a plurality of negative pressure suction holes arranged on the bottom wall of the first fixed platform 31 and used to suction and fix the bottom surface of the battery cell. The clamping assembly 312 comprises a clamping push block and a front push cylinder. A first retaining wall is formed on the first fixed platform 31. The clamping push block is driven by the front push cylinder to push the side of the battery cell against the first retaining wall, thereby achieving clamping and fixing of the battery cell. Through cooperation of the suction assembly 311 and the clamping assembly 312, the bottom surface of the battery cell and the two sides of the battery cell are fixed, so that the battery cell does not deviate or separate during folding, ensuring the fixity of the position of the battery cell and further improving the quality of double-battery-cell folding operation.

[0057] In the present embodiment, the structure of the second fixed platform 32 is the same as that of the first fixed platform 31, and will not be described here.

[0058] As a further optimization, the device for folding double battery cells to the BMU middle plate further comprises a middle plate positioning mechanism 6.

The pushing directions of the first pushing unit 62 and the second pushing unit 63 are perpendicular to each other.

[0060] It should be noted that the middle plate body is in a horizontal state on the middle plate positioning platform 61, after the positioning of the middle plate is completed, the adsorption unit 12 adsorbs and fixes the middle plate body, and then under the driving of the first driving unit 11, the middle plate is rotated to a vertical state and is transferred above the BMU plate positioning platform 21 to perform subsequent middle plate pasting operation and double-electricity-core folding operation.
