This invention relates to the field of automated packaging and robot control technology, specifically to a force-sensitive adaptive clamping system and method for fruit bag packaging. The system acquires a preset acceleration timing sequence during the clamping and conveying stage. It obtains the current normal force value and the finger-surface tangential acceleration signal through a clamping surface normal force sensing module and a tangential acceleration sensing module. Simultaneously, it acquires stress wave signals through a disturbance spring and a stress wave sensor. The two signals are compared in the time domain. If the waveform similarity exceeds a threshold, it is determined that the fruit inside the bag is disturbed, and a disturbance suppression flag is generated. If the tangential acceleration signal fluctuates while the stress wave signal is steady, it is determined that the interface is pre-slipping, and a slippage warning flag is generated. Only when a slippage warning flag is received and no disturbance suppression flag is received, the peak value of the tangential inertial force is predicted based on the preset acceleration timing sequence. The clamping safety margin is calculated in conjunction with the current normal force. If it is below the threshold, a clamping force pre-increase command is issued before the peak inertial force is reached.
