The utility model discloses an automatic lifting platform of a
vacuum coating machine, which belongs to the technical field of
vacuum coating machines and comprises a bottom plate, a top plate is arranged on the upper side of the bottom plate, a connecting plate is arranged on one side of the upper end of the top plate, a connecting
rope is arranged at one end of the connecting plate, placing seats are arranged on two sides of the other end of the connecting plate, and a supporting column is arranged on the lower side between the two placing seats. The top plate and the bottom plate are connected through a lifting
assembly. By arranging the lifting
assembly, when the top plate needs to be lifted, a first motor is started, the first motor drives a worm to rotate, the worm rotates to drive a
threaded rod to rotate through a worm gear, the
threaded rod rotates to enable a threaded cylinder to ascend and descend, meanwhile, a telescopic rod stretches out and draws back between the top plate and the bottom plate, and the threaded cylinder ascends and descends to push the top plate to ascend and descend; the screw rod does not rotate, the height of the top plate does not change, the lifting safety of the top plate is higher by arranging the lifting
assembly, and the lifting accuracy is higher.
