The low-energy PVD coating device comprises a sputtering cathode, the sputtering cathode is loaded with a target material, the target material and a substrate are oppositely arranged, and the target material generates film material particles under the action of an electric field of the sputtering cathode; the energy adjusting plate is positioned between the substrate and the sputtering cathode and is provided with a via hole; the collision particle pipeline is connected with the collision particle source, the collision particle source is internally provided with preset inert gas, a gas outlet end opening of the collision particle pipeline is formed in the energy adjusting plate, and the conveyed inert gas moves towards the target material; the kinetic energy of the inert gas is smaller than that of the film material particles.

The invention relates to an anti-gravity technology principle and a device, which are the vector sum of the resultant force of the axial torsion borne by a conjugate main shaft or an auxiliary shaft and the counter-acting force of the resultant force required by the conjugate suspension rotor for alternately carrying out fixed-shaft eccentric rotary motion and composite planar motion, wherein the counter-acting force is the axial torsion borne by the conjugate main shaft or the auxiliary shaft. The conjugated suspension rotor obtains the pre-collision impulse and the rebound space through sinking acceleration and spin acceleration, and in the non-elastic collision process under forced constraint of each other, energy exchange occurs between mass centers of the suspension rotor. And the pre-collision vertical impulse of the full mass center of the suspension rotor pointing below the horizontal line is changed into the rebound vertical impulse pointing above the horizontal line. Conjugated suspension rotors are reversely hung on respective driving double shafts by means of centrifugal force, are surrounded by the auxiliary shafts and the driving arms of the auxiliary shafts and rotate according to conjugate dynamic laws. The antigravity acts on a conjugate origin, is output along a conjugate axis and points to a collision point, and is derived from centrifugal force generated by eccentric rotation of a fixed shaft of the suspension rotor, counter-acting force in acceleration and deceleration processes, rebound impulse obtained by collision and counter-acting force of power torque borne by a main shaft or an auxiliary shaft.
