The invention relates to a detection method and device of a conveyor line skid location pin, the detection is convenient and precise and the cost is low. The technical scheme is that in the detectionmethod of the conveyor line skid location pin, a jig station is arranged on the conveyor line, which is characterized in that the device is provided with a transverse beam, two location holes are arranged on the transverse beam, the location holes are matched with the location pin of the jig; the device is also provided with a longitudinal beam, the transverse beam is fixed with the longitudinal beam, a detection hole corresponding to the reference position of the skid location pin is arranged on the longitudinal beam. During detection, the transverse beam is firstly fixed with the jig, and then the detection of the skid location pin is realized by judging whether the skid location pin corresponds to the detection hole of the longitudinal beam.
