controlling a battery string conveyor to drive a battery string to be subjected to film sticking to be output from an output end of the battery string conveyor, wherein the battery string to be subjected to film sticking is carried on a film belt at a feeding end of a film sticking conveying mechanism in the output process of the battery string conveyor;
and controlling the battery string conveyor to continuously convey the battery strings, and controlling the conveying belt of the film sticking conveying mechanism to drive the stacked battery strings and the film belt to be conveyed towards the discharge end of the film sticking conveying mechanism until the battery strings are all stacked on the film belt of the film sticking conveying mechanism.
10. The battery string lamination method of claim 9, further comprising: before a battery string to be filmed is output from the output end of the battery string conveyor, applying a front surface film on the battery string;
alternatively, the method further comprises: and after the battery string to be filmed is carried on a film belt at the feeding end of the film sticking conveying mechanism in the output process of the battery string conveyor, a front film is pasted on the battery string stacked on the film belt.
11. The battery string lamination method of claim 10, further comprising: hot-pressing the battery string with the front surface film pasted on the upper surface and the film belt pasted on the bottom surface by a hot-pressing device above the film pasting conveying mechanism;
alternatively, the method further comprises: the released front side film is hot-pressed while the front side film is released on the battery string by the front side film application device.
