The invention relates to the technical field of thickness detection, in particular to a robot servo spot welding plate thickness detection technology, which comprises the steps of digital quantity signal output, shutdown and warning, and the digital quantity signal output step comprises the steps of sensor installation, sensor data acquisition, signal processing, threshold setting and digital signal output. The sensor mounting step comprises the step of mounting a plurality of ultrasonic sensors, laser sensors and inductive sensors on a welding gun, the signal processing step comprises the step of filtering, amplifying and denoising, and the threshold value setting step comprises the step of setting a threshold value for judging whether the thickness of a metal plate meets specific requirements or not. In the digital signal output step, a system generates a digital signal as output according to whether the thickness of the metal plate exceeds or is lower than a set threshold value.
