As shown in fig. 1 to 3, the lamination process using the cell lamination apparatus includes the following steps: the unstacked cell units are sent to the lamination station 140 from above; the lamination table 140 is used for supporting the laminated cell units; the first follow-up mechanism 121 drives the first cell unit to be stacked to swing towards the second side of the stacked cell unit, so that an included angle is formed between the connected first cell unit to be stacked and the second cell unit to be stacked; the first to-be-stacked battery cell unit is connected with the first side of the stacked battery cell unit, and the first side and the second side of the stacked battery cell unit are opposite; the second follow-up mechanism 122 drives a second node 132, which is used for connecting the second cell unit to be stacked with the cell unit not to be stacked, to approach the first side of the stacked cell units; the first follow-up mechanism 121 and the second follow-up mechanism 122 are reset, and the first cell unit to be stacked and the second cell unit to be stacked naturally fall under the action of gravity to complete stacking, so that the stacked cell units are formed; two unstacked battery cell units connected with the second battery cell unit to be stacked fall down to form a next group of new first battery cell unit to be stacked and second battery cell unit to be stacked; and repeating the steps until a complete battery cell is stacked.

Specifically, in the above steps, the composite monomer pole piece 100 includes a plurality of cell units, each cell unit includes a positive pole piece and a negative pole piece, the composite monomer pole piece 100 includes two isolation films, the negative pole piece is disposed between the two isolation films, the positive pole pieces are alternately attached to the outer sides of the negative pole pieces, and the negative pole pieces and the positive pole pieces are separated by the isolation films; the positive plate and the negative plate are made of harder materials, the isolating membrane is made of softer materials, the pole pieces between two adjacent electric core units have certain gaps, and the gaps form nodes for connecting the two electric core units. The feeding mechanism 110 conveys the cells which are not stacked, the follow-up mechanism drives the cells to be stacked to move, and the stacking table 140 supports the stacked cells; the battery cell unit to be stacked comprises a first battery cell unit to be stacked and a second battery cell unit to be stacked, one end of the first battery cell unit to be stacked is connected with the first side of the stacked battery cell unit, and the connection position is a third node 133; the other end of the first cell unit to be stacked is connected with one end of the second cell unit to be stacked, and the connection position is a first node 131; the other end that the second waited to stack electric core unit is connected with the electric core unit that does not stack, and the junction is second node 132.

In the process of laminating the composite monomer pole pieces 100, sending out the non-stacked cell units in the composite monomer pole pieces 100 from the upper part, and fixing the first cell unit on the laminating table 140 to form a first stacked cell unit; the battery cell stacking device is also provided with a first driving device and a second driving device, the first driving device drives a first follow-up mechanism 121, and the first follow-up mechanism 121 drives a first battery cell unit to be stacked to swing towards the second side of the stacked battery cell unit; the second driving device drives the second follow-up mechanism 122, and the second follow-up mechanism 122 drives the second cell unit to be stacked to approach the first side of the stacked cell unit; wherein the first side that has stacked electric core unit is the one side that is connected with first electric core unit that to stack, and the second side that has stacked electric core unit is for having stacked electric core unit not with first one side that is connected of stacking electric core unit, and the first side that has stacked electric core unit corresponds with second side position. In order to avoid abrasion of positive plates on the cell units to be stacked by the first follow-up mechanism 121 and the second follow-up mechanism 122, when the first cell unit to be stacked and the second cell unit to be stacked fall to positions where stacking can be completed under the action of gravity, the first follow-up mechanism 121 and the second follow-up mechanism 122 are reset, and the first cell unit to be stacked and the second cell unit to be stacked are stacked under the action of gravity to form a stacked cell unit; two continuous non-stacking battery cell units that link to each other are waited to stack with the second and fall and become a next set of new first battery cell unit that should stack and battery cell unit that should stack are waited to stack with the second. The action of the lamination of the cell unit to be stacked is repeated until a complete cell is stacked, the action efficiency of the lamination is high, and the quality of the cell forming is good.

Further, the first cell unit on the composite monolithic pole piece 100 is fixed on the lamination stage 140 to form the first laminated cell unit. For example, as shown in fig. 1 to 3, a first cell unit on the composite cell pole piece 100 is fixed on the lamination stage 140. Specifically, after the composite monomer pole piece 100 is sent out, the first cell unit falling on the lamination table 140 is fixed on the lamination table 140, and forms the first stacked cell unit, and at this time, two consecutive cell units connected to the stacked cell unit form a first group of cell units to be stacked. After the first cell unit is sent out, the first cell unit is clamped through a manipulator and is pulled to the lamination table 140, and the lamination table 140 fixes the first cell unit in an adsorption mode, so that the position deviation of the subsequent cell unit lamination due to inertia is reduced, and the stability of the cell lamination action is improved; wherein the robot is not shown in the figure. It is conceivable that the first battery cell unit may also be pulled to the lamination table 140 by other pulling manners, and the lamination table 140 may further fix the first battery cell unit to the lamination table 140 by clamping, compressing, and the like, in this embodiment, the first battery cell unit is pulled to the lamination table 140 by a manipulator, and the first battery cell unit is fixed by the lamination table 140 in an adsorbing manner, which is not a specific limitation of the present invention.

Further, "the first follow-up mechanism 121 drives the first cell unit to be stacked to swing to the second side of the stacked cell unit, so that an included angle is formed between the first cell unit to be stacked and the second cell unit to be stacked, which are connected to each other," includes the following steps: the first following mechanism 121 drives the first node 131 between the first cell unit to be stacked and the second cell unit to be stacked, and rotates to the second side of the stacked cell unit by using the first cell unit to be stacked and the third node 133 between the stacked cell units as a rotation center. For example, as shown in fig. 1, the first follower mechanism 121 drives a first node 131 between the first cell unit to be stacked and the second cell unit to be stacked, and rotates toward the second side of the stacked cell unit with a third node 133 between the first cell unit to be stacked and the stacked cell unit as a rotation center.

Specifically, the first follow-up mechanism 121 includes an adsorption jig, and drives the first node 131 to swing toward the second side of the stacked cell units in an adsorption manner, where the first node 131 is a connection point between the first cell unit to be stacked and the second cell unit to be stacked; in addition, in the swing process of the first node 131, the first to-be-stacked cell unit and the third node 133 connected to the stacked cell unit are used as a rotation center to rotate to the second side of the stacked cell unit, and the first side of the stacked cell unit corresponds to the second side of the stacked cell unit. In the process that the first follow-up mechanism 121 drives the first node 131 to swing, including the component speed in the horizontal direction and the component speed in the vertical direction, the first node 131 can be driven to move in the horizontal direction, and meanwhile, the first node 131 can also be driven to move in the vertical direction, so that the first node 131 gradually approaches to the second side of the cell units to be stacked, and therefore the first cell units to be stacked are stacked on the stacking table 140. It can be understood that the first following mechanism 121 may further include a mechanical arm, and the first node 131 is driven to swing by clamping, in this embodiment, it is not right that the first following mechanism 121 includes an adsorption jig.

Further, "the second follower 122 drives the second node 132, which is connected between the second cell unit to be stacked and the non-stacked cell unit, and approaches the first side of the stacked cell units," includes the following steps: the second follower 122 drives the second node 132 to rotate toward the first side of the stacked cell units with the rotating first node 131 as a rotation center. For example, as shown in fig. 1, the second follower 122 drives the second node 132 to move toward the first side of the stacked cell units with the rotating first node 131 as a rotation center. Specifically, the second follow-up mechanism 122 includes an adsorption jig, and drives the second node 132 to swing to the first side of the stacked cell units in an adsorption manner, where the second node 132 is a connection point between the second cell unit to be stacked and the cell unit that is not stacked; during the movement of the second node 132, the first node 131 is used as a rotation center, and the second node moves to the first side of the stacked cell units. In the process that the second follow-up mechanism 122 drives the second node 132 to move, the process includes a component speed in the horizontal direction and a component speed in the vertical direction, and the second node 132 can be driven to move along the horizontal direction and simultaneously the second node 132 can be driven to move along the vertical direction, so that the second node 132 gradually moves towards the first side of the cell units to be stacked; the first follow-up mechanism 121 and the second follow-up mechanism 122 move in a matching manner, so that the included angle between the first cell unit to be stacked and the second cell unit to be stacked is gradually reduced until the first cell unit and the second cell unit to be stacked naturally fall under the action of gravity to complete stacking, and the first cell unit to be stacked and the second cell unit to be stacked become stacked cell units. It can be understood that the second following mechanism 122 may further include a mechanical arm, and the second node 132 is driven to swing by clamping, in this embodiment, it is not right that the second following mechanism 122 includes an adsorption jig.

Further, "the first follow-up mechanism 121 drives the first cell unit to be stacked to swing to the second side of the stacked cell unit, so that an included angle is formed between the first cell unit to be stacked and the second cell unit to be stacked, which are connected to each other," includes the following steps: the first follow-up mechanism 121 pushes the first cell unit to be stacked to rotate toward the second side of the stacked cell units in a swinging manner. For example, as shown in fig. 2 and fig. 3, the first follower mechanism 121 pushes the first cell unit to be stacked to rotate toward the second side of the stacked cell unit in a swinging manner. Specifically, the first following mechanism 121 is configured as a pendulum and is disposed on one side of the composite monomer pole piece 100, and the first following mechanism 121 rotates the first to-be-stacked cell unit to the second side of the stacked cell unit in a swinging manner, where the second side of the stacked cell unit is the side of the stacked cell unit away from the first to-be-stacked cell unit. The first follow-up mechanism 121 acts on a first node 131 where the first cell unit to be stacked and the second cell unit to be stacked are connected, and by pushing the first node 131 to move, the first cell unit to be stacked can move to the second side where the cell units are stacked, and meanwhile, the pole piece on the cell unit to be stacked is prevented from being damaged by the first follow-up mechanism 121. The pole pieces between two connected cell units are spaced apart sufficiently for the first follower 121 to act on the first node 131.

Further, "the second follower 122 drives the second node 132, which is connected between the second cell unit to be stacked and the cell unit not stacked, to approach the first side of the stacked cell units," includes the following steps: the second follower 122 holds the second node 132, and drives the second node 132 to move vertically downward to approach the first side of the stacked cell units. For example, as shown in fig. 2 and 3, the second follower 122 clamps the second node 132 and drives the second node 132 to move vertically downward to approach the first side of the stacked cell units. Specifically, the second follow-up mechanism 122 is provided as two clamping rollers, the second follow-up mechanism 122 is provided directly above the second side of the stacked cell units, the second node 132 is driven to move downwards, so that the angle between the first cell unit to be stacked and the second cell unit to be stacked is gradually reduced, and finally the cell units are stacked on the stacking table 140 to become new stacked cell units.

Further, in some embodiments of the present invention, in the process that the feeding mechanism 110 transports the unstacked battery cell unit to the stacking table 140, the unstacked battery cell unit passes through the limiting channel formed by the limiting device and is then transported to the second follow-up mechanism 122, and the limiting device with the limiting channel is arranged between the second follow-up mechanism 122 and the feeding mechanism 110, so that the movement path before the unstacked battery cell unit becomes to be stacked is limited within a certain range, and the position where the unstacked battery cell unit is avoided causing deviation, which affects the subsequent stacking action.

For example, as shown in fig. 1, the first following mechanism 121 is located below the second following mechanism 122, and both the first following mechanism 121 and the second following mechanism 122 include an adsorption jig. Specifically, each of the first follow-up mechanism 121 and the second follow-up mechanism 122 includes an adsorption jig, and the first node 131 and the second node 132 are respectively driven to move by the adsorption effect, and each of the first follow-up mechanism 121 and the second follow-up mechanism 122 includes a horizontal component speed and a vertical component speed, so that the first node 131 and the second node 132 are driven to move along the horizontal direction, and meanwhile, the first node 131 and the second node 132 can also be driven to move along the vertical direction.
