In order to further optimize the implementation effect of the present invention, in other embodiments, the rest of the characteristic techniques are the same, the difference is that S1 specifically includes the following steps:

S1.1: Determine the module type, different module types have different stacking methods;

S1.2: Along the flow direction of the line body, set up two sets of mechanical components in sequence outside the production line, specifically the first set of mechanical components 1 and the second set of mechanical components 2, according to the order of the grasping cells of the second set of mechanical components 2 and The stacking method of the module determines the position of the pre-stacked batteries of the first group of mechanical components 1;

Further, each robot has front and rear paws.

In some specific embodiments, taking Ningde era Dongfeng H97 module line and Changan E2 model as examples, the derivation process of the online body of the following module formula is as follows. The production line is A track and B track.

As shown in Figure 2, the formula information determination logic is as follows.

First of all, first determine the type of module, module 1P or module 2P, the polarity of the pole of the battery core of the module 1P is positive and negative alternately, and the polarity of the pole of the battery core of the module 2P is alternately positive and negative every two. The pre-stacking method of module 1P is stacking from B2 to A2, B1 to A1, and stacking in different lanes, as shown in Figure 3. The pre-stacking method of module 2P is stacking from A1 to A2, B1 to B2, and stacking in the same way, as shown in Figure 4.

Take the Changan E2 project as an example: the module types of the Changan E2 project are 1P24S, 1P12S_A, and 1P12S_B. There are three types of modules, and the module types are all module 1P, so the stacking method is confirmed to be stacked in different lanes.

The goal of the design is to stack the disordered batteries on the line in large packages into the ordered batteries in the shaping table 3 after the second set of mechanical components 2 are stacked to form the following qualified modules, as shown in Figure 5.

During the stacking process, the robot R8 first grabs the pre-stacked battery cells B2 and A2 for flipping, and the robot R9 grabs B1 and A1, and stacks the cells on the shaping table in sequence, because the robot has flipping during the grabbing process. The claw phenomenon is based on this order, and at this time it is stacked in different lanes. It can be known that the position of the battery cells on the pre-stacking table is shown in Figure 6.

Therefore, it is inferred that the position of the pre-stacked cells formed in the first group of mechanical components 1 is shown in Figure 7. Similarly, the positions of other cells in the pre-stacked cells formed by the first group of mechanical components 1 are shown in Figure 8 .

According to the grasping methods of the robot R3 and the robot R4 of the first group of mechanical components 1, the position of the battery cells in the large tray is judged, as shown in FIG. 9 .

Robot R3 grabs first, then robot R4 grabs again. Robot R3 grabs two sets of battery cells in two trays at a time with its front claws and rear claws. Put the core to the A1 position, and then put the battery cell grabbed by the rear paws into the A2 position.

After the robot R4 grabs the battery cell, first release the battery cell grabbed by the rear paw of the robot R4 to the B1 position, and then put the battery cell grabbed by the front paw to the B2 position, as shown in Figure 10.

According to the grasping methods of robot R3 and robot R4, the position of the battery cell in the large tray can be reversed, as shown in Figure 11.

According to the above steps, the cell position formula of the Changan E2_1P24S module can be deduced.

Then configure it through the background management website, and finally calculate the formula by MES and cooperate with PLC to complete the line body production. The background management website is responsible for the management and configuration of production lines, models, processes, formulas, and modules, and provides parameters, configuration and management for MISDATA programs.
