Therefore, the first driving piece drives the lamination platform 4 to move towards the upper part of the lamination platform 4, so that the distance between the composite pole piece 31 positioned on the lamination platform 4 and the composite pole piece 31 positioned on the clamping piece mechanism 5 is reduced, the phenomenon that the two composite pole pieces 31 are damaged due to dragging is avoided, and the lamination quality is ensured.
Specifically, a pressing plate 6 is arranged on the lamination platform 4, and the pressing plate 6 is used for pressing the composite pole piece 31 and the second pole piece on the lamination platform 4. It can be understood that, during lamination, the multiple composite pole pieces 31 and the multiple second pole pieces are stacked together from bottom to top in a set order, and in order to ensure that the stacked composite pole pieces 31 and the second pole pieces are fixed together, the composite pole pieces 31 and the second pole pieces are pressed against the lamination platform 4 by the pressing plate 6.
Specifically, the position of the second composite pole piece 31 adjacent to the lamination platform 4 is a clamping position, the number of the feeding manipulators is two, the two feeding manipulators respectively convey the second pole pieces to the clamping position, the two second pole pieces are respectively positioned on the upper side surface and the lower side surface of the composite pole piece 31, and the clamping mechanism 5 clamps the composite pole piece 31 and the two second pole pieces from the clamping position and conveys the composite pole piece 31 and the two second pole pieces to the lamination platform 4. Because the clamping mechanism 5 clamps the second composite pole piece 31 adjacent to the lamination platform 4 and conveys the second composite pole piece 31 to the lamination platform 4, the clamping mechanism 5 can drive the first composite pole piece 31 adjacent to the lamination platform 4 to move towards the lamination platform 4 during conveying, and the first composite pole piece 31, the second composite pole piece 31 and the second composite pole piece on the upper side and the lower side of the second composite pole piece 31 are stacked in a set sequence. The structure enables the single lamination operation of the clamping piece mechanism 5 to complete the lamination of four pole pieces, and has the characteristic of high lamination efficiency.
The lamination method is also provided, the lamination mechanism is adopted for lamination operation, and the specific steps are as follows:
step S1, one end of the long pole piece chain 3 penetrates through the feed roller assembly 2, the composite pole piece 31 positioned at one end of the long pole piece chain 3 is placed on the lamination platform 4, and a second pole piece is placed on the composite pole piece 31 positioned on the lamination platform 4;
step S2, the feeding manipulator transports the two second pole pieces to a position adjacent to the second composite pole piece 31 of the lamination platform 4, and the two second pole pieces are respectively located on the upper side and the lower side of the composite pole piece 31, and the composite pole piece 31 and the two second pole pieces form a pole piece assembly 32;
step S3, the clamping mechanism 5 clamps the pole piece assembly 32 and transports the pole piece assembly 32 to the lamination platform 4, and the lamination platform 4 is close to the pole piece assembly 32, so that the first composite pole piece 31 and the pole piece assembly 32 adjacent to the lamination platform 4 are sequentially stacked on the second pole piece above the lamination platform 4;
step S4, repeating step S3, so that the plurality of composite pole pieces 31 and the plurality of second pole pieces are stacked smoothly according to the setting to form a laminated battery cell, and a second pole piece is arranged between two adjacent composite pole pieces 31.
In this embodiment, the lamination platform 4 is used for placing the laminated composite pole piece 31 and the second pole piece, when lamination is started, the composite pole piece 31 located at one end close to the lamination platform 4 is fixed on the lamination platform 4 by manual operation, and the second pole piece is placed on the composite pole piece 31 located on the lamination platform 4. And then, carrying out lamination operation through automatic production equipment, wherein a first composite pole piece 31 adjacent to the lamination platform 4 is a first composite pole piece, a second composite pole piece 31 adjacent to the lamination platform 4 is a second composite pole piece, and the first composite pole piece is positioned between the lamination platform 4 and the second composite pole piece. And placing a second pole piece on the upper side and the lower side of the second composite pole piece through a discharging manipulator respectively so that the second composite pole piece and the two second pole pieces form a pole piece assembly 32, clamping the pole piece assembly 32 by using a clamping piece mechanism 5 and moving the pole piece assembly 32 to the upper side of the lamination platform 4 during lamination, wherein the pole piece assembly 32 is opposite to and spaced from the lamination platform 4, at the moment, a first composite pole piece 31 (namely, a first composite pole piece) adjacent to the lamination platform 4 is turned over to the upper side of the second pole piece on the lamination platform 4, and the first composite pole piece is positioned between the pole piece assembly 32 and the second pole piece placed on the lamination platform 4. The clip mechanism 5 continues to lower the pole piece assembly 32 until the pole piece assembly 32 is stacked with the composite pole piece 31 and the second pole piece on the lamination platform 4. At this point, the composite pole piece 31 located uppermost on lamination stage 4 has a second pole piece thereon. When the clamping piece mechanism 5 drives the pole piece assembly 32 to move, the lamination platform 4 approaches the pole piece assembly 32, so that the distance between the composite pole piece 31 on the lamination platform 4 and the composite pole piece 31 on the clamping piece mechanism 5 is reduced, further, the phenomenon that the two composite pole pieces 31 are dragged to be damaged is avoided, and the lamination quality is ensured. By circulating the operation, a plurality of composite pole pieces 31 and a plurality of second pole pieces can be stacked together, a second pole piece is arranged between two adjacent composite pole pieces 31, and meanwhile, the first pole piece and the second pole piece are separated by a diaphragm to form a laminated battery core.
Specifically, in step S3, when the clip mechanism 5 carries the pole piece assembly 32, the lamination stage 4 approaches the pole piece assembly 32 in the first direction. It can be understood that composite pole piece 31 located on lamination platform 4 is pressed on lamination platform 4 through pressing plate 6, and composite pole piece 31 held by clamping mechanism 5 is in a tight state with composite pole piece 31 on lamination platform 4, and when clamping mechanism 5 moves pole piece assembly 32, in order to move pole piece assembly 32 to the top of lamination platform 4, clamping mechanism 5 needs to move upward for a certain distance, so that pulling is formed between composite pole piece 31 held by clamping mechanism 5 and composite pole piece 31 on lamination platform 4. By moving lamination platform 4 in a first direction towards pole piece assembly 32, the spacing between the two composite pole pieces 31 can be reduced, avoiding the formation of tears that damage composite pole pieces 31.
Specifically, the clip mechanism 5 grips the pole piece assembly 32 and rotates about the axial direction of the clip mechanism 5, and the lamination platform 4 is raised to reduce the distance between the lamination platform 4 and the pole piece assembly 32. It will be appreciated that during lamination, the movement of the clamping mechanism 5 which clamps the pole piece assembly 32 will move the first composite pole piece towards the lamination platform 4. To stack the first composite pole piece beneath the pole piece assembly 32, the clip mechanism 5 needs to be rotated to rotate the pole piece assembly 32 about its intersection with the first composite pole piece. When the clip mechanism 5 rotates, the composite pole piece 31 on the pole piece assembly 32 and the composite pole piece 31 on the lamination platform 4 are pulled, and the lamination platform 4 is lifted to reduce the distance between the lamination platform 4 and the pole piece assembly 32, so that the composite pole piece 31 on the pole piece assembly 32 and the composite pole piece 31 on the lamination platform 4 are prevented from being pulled.
Specifically, in step S, after the pole piece assembly 32 and the composite pole piece 31 are stacked on the lamination platform 4, the lamination platform 4 is lowered, and the composite pole piece 31 located at the uppermost position of the lamination platform 4 is coplanar with the pole piece long chain 3. It can be understood that, before lamination, the long pole piece chains 3 are arranged along a horizontal plane, the composite pole piece 31 at one end of the long pole piece chain 3 is placed on the lamination platform 4, and the composite pole piece 31 on the lamination platform 4 and the long pole piece chain 3 are coplanar. With the increase of the number of the composite pole pieces 31 and the second pole pieces on the lamination platform 4, the composite pole piece 31 located at the top is separated from the plane where the pole piece long chain 3 is located, so that the distance between the composite pole piece 31 located at the top and the composite pole piece 31 on the pole piece assembly 32 is increased, the two form tension, and the composite pole piece 31 is easily damaged. In order to solve the problem, the lamination platform 4 is descended after lamination, so that the uppermost composite pole piece 31 and the pole piece long chain 3 are coplanar, the composite pole piece 31 can be prevented from being damaged, and the lamination quality is ensured.
