Clamping detection method and device of pressing assembly

The invention relates to the field of workpiece machining, in particular to a clamping detection method and device for a pressing assembly. The method comprises the steps that when a plate feeding instruction is received, an air clamp is opened, and a pressing assembly is controlled to be in a plate feeding state, so that a workpiece enters a machining area; after the workpiece enters the machining area, the air clamp is controlled to clamp the positioning component, and the pressing assembly is controlled to clamp the workpiece; a grounding sensor is connected with each pressing part so as to detect first grounding information of each pressing part; and according to the corresponding first grounding information, whether the pressing assembly clamps the workpiece or not is detected. Whether the voltage difference exists at the two ends of the pressing assembly or not is detected in real time through the grounding inductor, whether the pressing assembly clamps the workpiece or not can be fed back and confirmed
