Finished aluminum foil plate shape offline dynamic detecting automatic control system and use method thereof

The invention discloses finished aluminum foil plate shape offline dynamic detecting automatic control system capable of acquiring the foil face string bubble area quantitation value in a sampling inspection section and precise plate shape data and a use method thereof. The system comprises a precision mechanical foil supply system, a man-machine interaction interface and an NX controller. The usemethod of the system comprises the steps that 1, the primary output rotating speed of a film supply motor and the damping value of a magnetic powder brake are set; 2, the torque of a driving roll, the rotating speed of the driving roll, the conversion efficiency, the film width, the film thickness, the correction coefficient and the compensation coefficient are set, and the NX controller controlsthe driving roll to pull the film; and 3, the load of the aluminum film and the torque of the driving roll are adjusted, and the load of the aluminum film is kept dynamically constant when the set torque T0 is equal to FR. By means of the system and method, the actual condition of the quality of the same batch of offline products can be accurately reflected, the detecting efficiency is high, andthe technical performance stability of equipment is good.
