The invention provides a battery core lamination device.
In the embodiment of the present invention, referring to fig. 1 to 5, the battery cell lamination device is applied to a battery cell production line, the battery cell production line includes two parallel feeding mechanisms 500 for transporting pole pieces, the two feeding mechanisms 500 each have a material taking station 510, and the battery cell lamination device includes:
the positioning tables 100 are at least two, the positioning tables 100 are provided with deviation rectifying structures, the positioning tables 100 are positioned between the two feeding mechanisms 500, the positioning tables 100 are arranged corresponding to one feeding mechanism 500, and the deviation rectifying structures are used for adjusting the pole pieces to preset postures;
lamination stage 200, locate between two opposing positioning stages 100, lamination stage 200 is used for the pole pieces from positioning stage 100 to stack into lamination electric core;
a transport mechanism 300 reciprocally movable between the positioning stage 100 and the lamination stage 200 for transporting the pole pieces of the positioning stage 100 to the lamination stage 200; and
the material taking mechanisms 400 are at least two, one material taking mechanism 400 is arranged corresponding to one positioning table 100, the material taking mechanism 400 is provided with at least one material taking arm 410, and the material taking arm 410 can rotate reciprocally between the corresponding positioning table 100 and the corresponding material taking station 510 around the rotation center of the material taking arm 410, so as to transport the pole piece of the corresponding material taking station 510 to the corresponding positioning table 100.
According to the technical scheme, the pole pieces on the feeding mechanism 500 are transported to the positioning table 100 by adopting the material taking mechanism 400, so that the transportation of the pole pieces is converted into the material taking mechanism 400 which is independently arranged by the reversing mechanism on the linear motor 320 in the process of stacking the pole pieces into laminated battery cells, wherein the material taking arm 410 on the material taking mechanism 400 can rotate between the material taking station 510 and the positioning table 100 around the rotation center of the material taking mechanism, compared with the reversing mechanism on the linear motor 320, the failure rate of the material taking mechanism 400 is lower, the production continuity of the laminated battery cells is better, and the material taking mechanism 400 directly rotates around the rotation pivot and is not limited by the transportation mechanism 300, so that the transportation rate and the production efficiency of the pole pieces are improved. After the pole piece is placed on the positioning table 100, the deviation rectifying structure arranged on the pole piece can adjust the relative position of the pole piece and the positioning table 100, and the pole piece is adjusted to be in a preset gesture through the matching of the relevant positioning structure on the positioning table 100.
Specifically, the two picking mechanisms 400 are disposed corresponding to the picking stations 510 of the two feeding mechanisms 500, one picking station 510 provides the positive electrode sheet 600, the other picking station 510 provides the negative electrode sheet 700, so that when the picking arm 410 of one picking mechanism 400 picks up the positive electrode sheet 600 at the corresponding picking station 510, the picking arm 410 of the other picking mechanism 400 picks up the negative electrode sheet 700 at the corresponding picking station 510, the two picking arms 410 rotate around the respective rotation centers from the corresponding picking stations 510 to the corresponding positioning tables 100, respectively, then the positive electrode sheet 600 and the negative electrode sheet 700 are placed on the corresponding positioning tables 100, then the two picking arms 410 rotate back to the respective picking stations 510, and at the same time, the deviation correcting structures on the two positioning tables 100 adjust the corresponding electrode sheets to the preset postures, and then the transporting mechanism 300 sequentially transports the electrode sheets on the two positioning tables 100 to the lamination table 200. This reciprocates so that the laminated cells are stacked at lamination station 200. It should be noted that, the positive electrode sheet 600 and the negative electrode sheet 700 in the preset postures meet the transportation requirement of the transportation mechanism 300, and after being transported by the transportation mechanism 300, the laminated battery cells can be directly stacked on the lamination table 200, where the laminated battery cells are formed by alternately stacking the positive electrode sheet 600 and the negative electrode sheet 700 in sequence.
In an embodiment, referring to fig. 1 to 5, in the conveying direction of the feeding mechanism 500, two material taking mechanisms 400 are disposed at the upstream or downstream of the corresponding positioning table 100, or one material taking mechanism 400 is disposed at the upstream of the corresponding positioning table 100, and the other material taking mechanism 400 is disposed at the downstream of the corresponding positioning table 100. It should be noted that, in this embodiment, the tab orientations of the pole pieces on the two feeding mechanisms 500 are all opposite to the material taking mechanism 400. Thus, when the two material taking mechanisms 400 are located at the upstream of the corresponding positioning tables 100, the tabs of the stacked lamination cells on the lamination table 200 are located at the same side; when one extracting mechanism 400 is located at the upstream of the corresponding positioning table 100 and the other extracting mechanism 400 is located at the downstream of the corresponding positioning table 100, the tabs of the stacked laminated cells on the lamination table 200 are located at opposite sides, so as to realize the production of laminated cells on the same side of the tabs or laminated cells on different sides of the tabs. Further, the cell lamination device may be provided with a plurality of positioning tables 100 and a plurality of material taking mechanisms 400, so as to realize synchronous production of lamination cells on the same side of the tab and lamination cells on different sides of the tab in one cell lamination device.
In an embodiment, referring to fig. 1 to 5, one lamination stage 200 and two positioning stages 100 form a stacking mechanism, and a plurality of stacking mechanisms are provided, and the material taking mechanism 400 and the stacking mechanism are alternately arranged in the conveying direction of the feeding mechanism 500. In this way, by adjusting the rotation rate of the material taking arm 410 and the feeding rate of the feeding mechanism 500, at least one material taking mechanism 400 can take materials for two groups of stacking mechanisms, so that the production efficiency of the laminated battery cell is improved. Of course, in another embodiment, two sets of stacking mechanisms may be disposed adjacent to each other, and the feeding mechanism 400 is disposed correspondingly upstream and downstream of the two sets of stacking mechanisms, so as to feed the two sets of stacking mechanisms.
Further, in the present embodiment, referring to fig. 1 to 5, the extracting mechanism 400 is disposed between two adjacent stacking mechanisms, the extracting mechanism 400 has two extracting arms 410, and an included angle between the two extracting arms 410 is equal to an included angle formed by the corresponding extracting station 510 and a corresponding positioning table 100 and a rotation center of the extracting arm 410, respectively. It will be appreciated that when one of the take out arms 410 of the take out mechanism 400 corresponds to the positioning stage 100, the other take out arm 410 corresponds to the take out station 510. Thus, when one of the material taking arms 410 obtains the positive electrode sheet 600 or the negative electrode sheet 700 from the material taking station 510, the two material taking arms 410 rotate in the positive direction synchronously, so that the material taking arm 410 obtaining the positive electrode sheet 600 or the negative electrode sheet 700 corresponds to the positioning table 100 of a stacking mechanism, and the positive electrode sheet 600 or the negative electrode sheet 700 is placed on the positioning table 100, and meanwhile, the other material taking arm 410 corresponds to the material taking station 510 and obtains the positive electrode sheet 600 or the negative electrode sheet 700 from the material taking station 510; then, the two material taking arms 410 rotate in opposite directions synchronously, the material taking arm 410 carrying the positive electrode sheet 600 or the negative electrode sheet 700 rotates to the positioning table 100 on the other stacking mechanism, the positive electrode sheet 600 or the negative electrode sheet 700 is placed on the positioning table 100, and meanwhile, the other material taking arm 410 corresponds to the material taking station 510 and obtains the positive electrode sheet 600 or the negative electrode sheet 700 from the material taking station 510 again. The reciprocating manner is adopted to realize that one material taking mechanism 400 supplies materials for two stacking mechanisms in one material taking period, so that the production efficiency of the laminated battery cell is improved. Of course, in other embodiments, only one take out arm 410 may be provided with one take out mechanism 400.
Specifically, in the present embodiment, please continue to refer to fig. 1 to 5, two picking mechanisms 400 are disposed between two adjacent stacking mechanisms, and when two picking arms 410 of one picking mechanism 400 are respectively located at the corresponding picking station 510 and the corresponding positioning table 100 in one stacking mechanism, two picking arms 410 of the other picking mechanism 400 are respectively located at the corresponding picking station 510 and the corresponding positioning table 100 in the other stacking mechanism. It should be noted that, the laminated battery cell is formed by alternately stacking the positive electrode sheet 600 and the negative electrode sheet 700, so, between two adjacent stacking mechanisms, when one material taking mechanism 400 supplies material for one stacking mechanism, the other material taking mechanism 400 supplies material for the other stacking mechanism synchronously, then, the two material taking mechanisms 400 supply material for different stacking mechanisms alternately, and the two material taking mechanisms 400 adapt to the alternate stacking sequence of the positive electrode sheet 600 and the negative electrode sheet 700 on the laminated battery cell in the two stacking mechanisms, thereby improving the production efficiency of the laminated battery cell. Of course, in other embodiments, two take off mechanisms 400 between two adjacent stacking mechanisms may be synchronized to feed one stacking mechanism.
Further, in the present embodiment, referring to fig. 1 to 5, the angle between the two reclaiming arms 410 of the reclaiming mechanism 400 is a right angle. In this embodiment, the line in which the length direction of the pole piece on the positioning table 100 is located is perpendicular to the line in which the length direction of the pole piece on the feeding mechanism 500 is located, and the angles between the positioning table 100 and the corresponding material taking station 510 and the connecting line of the rotation center of the corresponding material taking mechanism 400 are respectively right angles, so that the two material taking arms 410 of the material taking mechanism 400 are mutually perpendicular, and the pole piece on the material taking station 510 can be placed in a deviation rectifying structure in a state closer to a preset state, thereby improving the transportation efficiency of the material taking mechanism 400, and meanwhile, the situation that the posture of the pole piece extracted by the material taking arm 410 from the material taking station 510 is too different from the input posture of the deviation rectifying structure on the positioning table 100 is avoided, so that the deviation rectifying structure is difficult to adjust the pole piece to the preset posture. Of course, in other embodiments, on the premise that the positioning table 100 can adjust the pole pieces with various postures to the preset posture, the included angle between the two material taking arms 410 of the material taking mechanism 400 only needs to be adapted to the included angles between the positioning table 100 and the corresponding material taking station 510 and the rotation center of the material taking mechanism 400.
In an embodiment, referring to fig. 1 to 5, the transporting mechanism 300 includes a linear motor 320 and a guide frame 310, the extending direction of the guide frame 310 is parallel to the distributing direction of the lamination table 200 and the positioning table 100, and the linear motor 320 can reciprocate along the guide frame 310 above the lamination table 200 and the positioning table 100. In this embodiment, the stacking posture of the pole pieces on the lamination table 200 is consistent with the preset posture on the positioning table 100, so that after the linear motor 320 obtains the positive pole piece 600 or the negative pole piece 700 from the positioning table 100, the linear motor 320 moves linearly along the guide frame 310, which avoids the interference of the linear motor 320 on the positive pole piece 600 or the negative pole piece 700 during the transportation process, and ensures the forming rate of the lamination battery core on the lamination table 200. Of course, in other embodiments, the transporting mechanism 300 may transport the positive electrode sheet 600 or the negative electrode sheet 700 from the positioning table 100 to the corresponding lamination table 200 through an air cylinder, or the motor may reciprocate in an arc line without interfering with the posture of the pole piece during the process of transporting the pole piece.
Further, in the present embodiment, referring to fig. 1 to 5, two linear motors 320 are provided, and the two linear motors 320 perform alternating reciprocating linear motion between the lamination stage 200 and the respective corresponding positioning stages 100 to transport the pole pieces of the respective corresponding positioning stages 100 to the lamination stage 200. It should be noted that, two linear motors 320 are disposed in the transport mechanism 300 in the same stacking mechanism, so that one linear motor 320 is only responsible for transporting the negative electrode sheet 700, the other linear motor 320 is only responsible for transporting the positive electrode sheet 600, and the two linear motors 320 alternately reciprocate on the lamination stage 200 and the respective corresponding positioning stages 100 to alternately stack the positive electrode sheet 600 and the negative electrode sheet 700 on the lamination stage 200 at a time. Of course, in other embodiments, only one linear motor 320 may be provided within one stacking mechanism.
Further, in this embodiment, referring to fig. 1 and 2, a linkage structure 800 is disposed between the corresponding reclaiming mechanism 400 and the transporting mechanism 300, the linkage structure 800 includes a reciprocating screw 830, and a worm gear 810 and a worm 820 meshed with each other, the worm 820 is coaxially disposed with the rotation center of the reclaiming arm 410, the worm 820 is coaxially linked with the reciprocating screw 830, the reciprocating screw 830 is disposed in the guide frame 310, and the axial direction thereof is parallel to the extending direction of the guide frame 310, the linear motor 320 can move along the axial direction of the reciprocating screw 830 through a slider 840 sleeved on the reciprocating screw 830, when the reclaiming arm 410 on the reclaiming mechanism 400 rotates, the worm gear 810 drives the worm 820 to rotate, and then drives the screw 830 to rotate, so that the linear motor 320 moves along the axial direction of the reciprocating screw 830, and the rotation of the reclaiming arm 410 and the linear motion of the linear motor 320 are linked, wherein the transmission ratio of the worm gear 810 and the worm 820 is adapted to the rotation range of the reclaiming arm 410 and the movement range of the linear motor 320.
In another embodiment, the cell lamination apparatus further includes a controller (not shown), which controls the transporting mechanism 300 and the extracting mechanism 400, when one extracting mechanism 400 feeds one positioning table 100 on one stacking mechanism, the controller controls the linear motor 320 on the corresponding transporting mechanism 300 to transport the pole piece on the other positioning table 100 on the stacking mechanism to the lamination table 200, and when the extracting mechanism 400 finishes feeding the positioning table 100 of the lamination assembly, the controller controls the linear motor 320 to transport the pole piece from the positioning table 100 to the lamination table 200. Similarly, between two adjacent stacking mechanisms, the two material taking mechanisms 400 and the linear motors 320 in the two stacking mechanisms are controlled by the controller to be alternately performed in a plugboard mode, so that the operation continuity of the cell lamination device is ensured, and the production efficiency of laminated cells is improved.
