The semicircular sealing plate 9 is attached to the surface of the vacuum chamber 2, which is in contact with the inner wall of the vacuum chamber 3 by applying a predetermined pressure to maintain the fit between the two surfaces.
The working process is as follows:
firstly, according to the spacing distance parameter between the substrate 13 and the target 7 selected by the coating test, the position of the fastening screw 15 on the reference scale mark 12 is adjusted, so that the position of the suction assisting device 2 on the lifting table 5 is adjusted. After the sealing cover 4 is closed, the equipment is started, and when the equipment works normally, the vacuum pump starts to pump out gas, and the gas is pumped out through the exhaust port 1.
