In this embodiment, a cell stacking method is provided, and fig. 2 is a first flowchart of the cell stacking method of this embodiment, and referring to fig. 2, the process includes the following steps:

step S201, acquiring a number of first total battery cells that need to be stacked in a first current target battery cell module, determining parity of the number of the first total battery cells, and issuing an odd-numbered logic policy when the number of the first total battery cells is determined to be an odd number.

The first current target battery cell module is formed by stacking a plurality of first total battery cells, the types of the stacked first current target battery cell modules are different according to the different number of the first total battery cells, and especially when the number of the first total battery cells is different from that of the first total battery cells in odd number and even number, the mode that the first total battery cells are stacked into the first current target battery cell module is greatly different. Because of the above differences, it is necessary to obtain the number of first total cells to be stacked of each first current target cell module, especially parity information of the number of first total cells to be stacked, before stacking each first current target cell module, and directly determine the stacking manner of the first total cells. The parity of the number of the first total cells to be stacked is different, and the stacking manner of the first total cells is also different. When the number of the first total battery cells is determined to be an odd number, the stacking mode of the first total battery cells needs to be based on a preset odd number logic strategy. Therefore, when the number of the first bus cells to be stacked is an odd number, the odd-numbered logic policy needs to be issued to the stacking system.

Step S202, judging the number of first sub-cells required by the next stacking process according to the number of stacked cells of the first current target cell module; and when the number of the first sub-battery cores required in the next stacking process is an odd number, executing an odd logic strategy to enable the number of the first actual battery cores on the production line to be the same as the number of the first sub-battery cores.

The stacking of the battery cells is a gradually overlapping process, and to complete the stacking of a first current target module, different batches of first sub-battery cells are required to be continuously transported to a stacking station for stacking. For example: the method comprises the steps that a first current target battery cell module comprising 16 battery cells is divided into 4 batches of first sub-battery cells for transportation and stacking in a mode of loading and matching 4 battery cells, and the number of the first sub-battery cells stacked in the last batch is 4; a first current target battery cell module comprising 11 battery cells is divided into 3 batches of first sub-battery cells for transportation and stacking in a mode of loading and matching 4 battery cells, and the number of the first sub-battery cells stacked in the last batch is 3; the way of stacking 4 cells is different from the way of stacking 3 cells.

Therefore, it is necessary to determine the number of first sub-cells required for the next stacking process according to the number of stacked cells of the first current target cell module, so as to determine which stacking logic is to be executed in the next stacking process. And when the number of the first sub-battery cores required in the next stacking process is an odd number, executing an odd logic strategy, and forming first actual battery cores on a production line, wherein the number of the first actual battery cores is the same as the number of the first sub-battery cores.

Step S203, stacking a first actual cell on the production line to a first current target cell module.

And according to the determined odd-numbered logic strategy, enabling the number of the first actual electric cores on the production line to be the same as the number of the first sub-electric cores, and stacking the first actual electric cores to a first current target electric core module. The stacking can move the first actual battery cell to the stacking table through the servo clamping jaw, the servo clamping jaw loosens the first actual battery cell after the first actual battery cell reaches the designated coordinate, and the first actual battery cell is stacked to the first current target battery cell module.

Through the steps, the number of first main battery cores required to be stacked by a first current target battery core module is obtained, and when the number of the first main battery cores is judged to be odd, an odd-numbered logic strategy is issued; judging the number of first sub-cells required by the next stacking process according to the number of stacked cells of the first current target cell module; when the number of the first sub-cells required in the next stacking process is an odd number, executing an odd number logic strategy, and enabling the number of the first actual cells on the production line to be the same as the number of the first sub-cells by grabbing redundant cells from the production line to the material supplementing table or grabbing cells from the material supplementing table to the production line; pile up first current target electric core module with first actual electric core on producing the line, to piling up of odd electric core after accomplishing. The problem of exist among the correlation technique to pile up odd number electric core and need increase equipment cost is solved, realized piling up the electric core module that equipment can enough pile up the even number with same set of electric core, also can pile up the electric core module of odd number, improve production efficiency.

Fig. 3 is a specific flowchart of executing an odd-numbered logic strategy in this embodiment, referring to fig. 3, in some embodiments, when the number of the first sub-cells required by the next stacking process is odd, the executing the odd-numbered logic strategy to make the first actual cell number on the production line the same as the first sub-cell number includes:

s301, if the number of the first initial electric cores on the production line is larger than N, and the position for placing the electric cores is arranged on the material supplementing platform, grabbing redundant electric cores on the production line to the material supplementing platform to enable the number of the first residual actual electric cores on the production line to be N; and N is the number of the first sub-battery cores required by the next stacking process, and is an odd number.

S302, if the number of the first initial electric cores on the production line is smaller than or equal to N, the electric cores on the material supplementing platform are grabbed to the production line under the condition that the sum of the number of the electric cores on the production line and the number of the electric cores on the material supplementing platform is larger than or equal to N, and the number of the first actual electric cores on the production line meets N. And N is the number of the first sub-battery cores required by the next stacking process, and is an odd number.

Optionally, N is 3. Under the condition that N is 3, if the existing electric cores of the production line just meet 3 electric cores, the processing is not carried out, and the next stacking step is directly carried out; if the number of the existing electric cores of the production line is less than 3, the mechanical arm automatically grabs the electric core of the material supplementing platform to the production line for formula processing, the electric core is processed after the formula processing, and the processed electric core mechanical arms are piled up after being grabbed two by two; if it is more than 3 to produce the current electric core of line, then the manipulator snatchs 1 to the material filling bench with producing the line electric core automatically, then the electric core carries out the prescription and handles, and the prescription is handled the aftertreatment electric core, and two liang of back snatchs of electric core manipulator after handling piles up. In an optional embodiment, there are 3 positions for placing the electric core on the replenishing table, and therefore, before the manipulator automatically grabs 1 production line electric core onto the replenishing table, it is necessary to determine whether there is a position for placing the electric core on the replenishing table. If the feeding table has no position, the relevant position on the feeding table needs to be emptied to place the battery cell grabbed from the production line.

Through the steps, the requirement of stacking odd electric cores is met by grabbing redundant electric cores to the material supplementing platform or grabbing the electric cores to the production line from the material supplementing platform on the same production line based on the existing equipment, the problem that the stacking of the odd electric cores needs to increase the equipment cost in the related technology is solved, and the purpose of stacking the first current target electric core module including the odd electric cores by using the same electric core stacking device is achieved.

(1) and (4) battery core feeding and battery core pretreatment.

On a production line, after 4 battery cells are loaded, a signal is triggered through an in-place detection mechanism (such as a photoelectric sensor), a PLC (programmable logic controller) acquires the signal and then sends a command to control a detector to carry out multiple detections (such as thickness, height and the like) on the battery cells, and the detection values are fed back to the PLC. The PLC controller forwards the detection value to an MES manufacturing execution system, the MES manufacturing execution system judges the detection value according to a set standard range, and feeds back a judgment result (OK/NG) to the PLC controller after the judgment is finished, and the PLC controller executes different operations according to the result: when the judgment result is OK, the battery core operates normally; and when the judgment result is NG, discharging the current battery core. After the processing is finished, the PLC commands the transplanting mechanism to move 4 electric cores to the next station (the electric core formula is turned over).

(2) And (5) overturning the battery cell formula.

The 4 electric cores trigger signals through the in-place detection mechanism, the PLC sends the trigger request to the MES manufacturing execution system, and the MES manufacturing execution system calculates the current formula logic (odd logic or even logic) according to the counter (calculating the number of the produced electric cores). After the formula logic is confirmed, the odd logic or the even logic is issued to the PLC, the PLC judges the number of the battery cells of the feeding table and the number of the battery cells of the production line according to the odd logic or the even logic, the odd logic strategy or the even logic strategy is further executed according to a judgment result, the battery cells are placed on a tray of the production line by a manipulator according to the formula, a trigger completion signal is sent to the PLC after the action is completed, and the PLC controls the operation of a production line and transfers the battery cells on the tray to the next station.

(3) And (6) pre-processing battery cell stacking.

After the battery cell tray is in place, the in-place stopper is triggered, the battery cell is operated manually, the completion button is pressed after the operation is completed, the stopper is triggered to move away, and the tray continuously rotates to the next station (namely, the battery cells are pre-stacked).

(4) The electric cores are pre-stacked.

The tray drives electric core and passes through the detection mechanism trigger signal that targets in place, the PLC controller is according to the signal that targets in place, start the servo clamping jaw single of triaxial and press from both sides 2 electric cores and get, place and pile the bench in advance, the servo clamping jaw of triaxial loosens electric core after reacing appointed coordinate parameter, then it gets back to tray electricity core top and continues to press from both sides and get 2 electric cores (shielding 1 electric core's sensor under the odd number logic to press from both sides, 1 electric core is got to repeated pile logic in advance, accomplish single tray pile in advance after, the carousel will pile in advance that electric core is rotatory 180.

(5) And stacking the battery cells.

The rotation targets in place and triggers the signal that targets in place, the PLC controller starts servo clamping jaw according to the signal that targets in place and moves the good electric core of prestack to piling up the platform, the electric core is loosened to the clamping jaw after arriving appointed coordinate parameter, then get back to tray electricity core top and continue to press from both sides and get electric core (press from both sides under the even number logic strategy and get 2 electric cores, press from both sides under the odd number logic strategy and get 1 electric core), repeat the prestack logic, until piling up the counter and reaching the settlement formulation value, the platform that shuttles back will pile up the module after accomplishing and send to next station, the empty platform that shuttles back of next station returns.
