OCV test and NG removal station introduction:

After the product flows from the double-speed chain to this station, the OCV test is performed first to ensure that the voltage and impedance meet the product process requirements;

After the OCV test is completed, enter the next NG removal station, and the NG products will be placed on the NG product conveyor belt through the three-axis handling module to flow out; the OK products are stored in the refilling position, waiting for refilling;

 

4.2 Polarity Adjustment, Gluing

 

 

Flip gripping and manipulator gluing station introduction:

After the product completes the OCV test, the station is driven by the double-speed chain, and after passing the polarity test, the product is clamped and turned over;

After turning over, go to the next manipulator gluing station to automatically gluing the battery cells

 

4.3 Stacked Turntable:

 

 

1. Action process: The stacking robot grabs materials from the cell conveying line and the end plate feeding table respectively, and performs stacking operations according to the serial parallel order of the module formula. This stacking method can be flexibly compatible with modules with different formula serial parallel orders. combination.

2. The gripper is controlled by a robot, and the gripper is designed with a photoelectric induction cell in place. The module stacking platform adopts a fixed slope double-station design. Each station contains four sets of fixtures, and four batteries can be placed at the same time at a time. When station A is stacking, station B performs the moving work before extrusion synchronously, and the double stations alternately, so as to improve the efficiency of stacking and moving.
