step C2: the visual detection system detects the position of a filter membrane on the filter membrane conveying belt and the position of a laminating assembly box on the finished product conveying belt;

step C3: the membrane stacking robot arm clamps the filter membrane, places the filter membrane into a membrane stacking assembly box, and records the membrane stacking times;

step C4: judging whether the membrane stacking times are equal to the membrane stacking number N or not, if not, continuing membrane stacking, and if so, stopping membrane stacking by a membrane stacking robot arm;

step C5: and (4) outputting the membrane stacking assembly boxes fully stacked with the filter membranes by starting the finished product conveyer belt, and simultaneously transporting the empty membrane stacking assembly boxes to one side of a membrane stacking mechanical arm, and starting the membrane stacking mechanical arm to start the next membrane stacking operation.

9. The automatic film laminating machine control method according to claim 5, wherein: also included is a membrane stacking method comprising the steps of:

step C1: detecting whether a filter membrane exists in the filter membrane temporary storage frame or not by using an induction detector, if so, continuing the transportation operation of the filter membrane by using the feeding device, otherwise, clamping the empty filter membrane temporary storage frame without the filter membrane by using the feeding device, and placing the filter membrane temporary storage frame on the placing platform;

step C2: empty frame inductive switch detects the filter membrane frame of keeping in on the place the platform, start push rod device will the filter membrane frame of keeping in pushes away the roller on, and the filter membrane frame landing of keeping in is to the bottom of roller.
