Assembly line damage monitoring and early warning device

The utility model discloses an assembly line damage monitoring and early warning device which comprises a double-guide-rail frame, and two guide rails are arranged on the double-guide-rail frame. 1, aservo motor drives a gear disc to rotate; the gear disc drives the outer gear ring to rotate; therefore, the suspension arm can do circular motion under the rotation of the outer gear ring; a pistonpush rod driven by an electric cylinder is arranged above a first supporting plate, and the first supporting plate is driven to move up and down under the action of the piston push rod, so that the horizontal height of the radio frequency reader-writer is conveniently adjusted, and the scanning efficiency of the radio frequency reader-writer on radio frequency tags around objects on an assembly line is improved; and 2, the adjusting knob is arranged between the suspension arm and the outer frame, and the radio frequency reader-writer can be adjusted to rotate at a certain angle, so that the scanning range of the scanne
