One end of the connecting member 110 is fixedly connected to a feeding gripper (not shown) of the laser tailor-welding mechanism, and the other end is fixedly connected to the fixing base 120. The fixing base 120 has a sensor mounting hole, and the sensor 130 is fixedly connected to the fixing base 120 through the sensor mounting hole. The sensor 130 is a double-sheet sensor and is used for detecting whether the number of the gripping materials of the feeding gripper is multiple. In this embodiment, the sensor 130 is a single-side contact type electromagnetic induction dual material detection sensor.

The floating head 140 has a central through hole 141 and is coaxially fitted over the sensing end (lower end) of the sensor 130 through the central through hole 141. One ends (lower ends) of the plurality of guide shafts 150 are fixedly coupled to the floating head 140, and the plurality of guide shafts 150 are disposed at intervals in the circumferential direction of the floating head 140, the guide shafts 150 being disposed in the axial direction of the central through hole 141.
