The invention relates to an automatic feeding and discharging machine for a vibration absorber in the laser welding process, in particular to equipment used for automatically performing feeding and discharging on the vibration absorber in the laser welding process of the vibration absorber. The automatic feeding and discharging machine comprises a base plate; the side face of the base plate is connected with a piston rod of a transverse cylinder; a lifting cylinder is fixed at the bottom of the base plate; a connecting disc is arranged at the lower end of a piston rod of the lifting cylinder; a three-jaw chuck is fixed at the lower end of the connecting disc; a clamping jaw capable of snatching up the silicon oil vibration absorber is arranged on the lower end face of the three-jaw chuck. The silicon oil vibration absorber is provided with a sensor positioning block, and a position sensor is fixed on the sensor positioning block. The automatic feeding and discharging machine for the vibration absorber is simple, compact and reasonable in structure, small in size, convenient to use, stable and reliable in working and capable of quickly and stably feeding and discharging the vibration sensor.
