The magnetic material vacuum coating machine of claim 6, characterized in that: still include rotation driving element, rotor arm and place the subassembly, it passes through to snatch the subassembly the rotor arm with the linkage of rotation driving element is connected, rotation driving element can drive thereby the rotor arm rotates and makes it snatchs the subassembly upset, it can move extremely to place the subassembly snatch the subassembly perhaps first lifting unit works as rotation driving element drives it will to snatch behind the subassembly upset material piece place the subassembly will it puts back the material loading dish to snatch the material piece that the subassembly snatched.

8. The magnetic material vacuum coater of claim 5, wherein: the first lifting assembly comprises a first transportation assembly and a first lifting driving device, the first transportation assembly is in linkage connection with the first lifting driving device, the first lifting driving device can drive the first transportation assembly to lift, the second lifting assembly comprises a second transportation assembly and a second lifting driving device, the second transportation assembly is in linkage connection with the second lifting driving device, and the second lifting driving device can drive the second transportation assembly to lift.

9. A coating method comprising the magnet vacuum coater according to any one of claims 1 to 8, further comprising the steps of:

s3: the first transportation assembly is lifted and communicated with the overturning assembly, the material carrying disc moves from the overturning assembly to the first transportation assembly, the first transportation assembly is lowered and communicated with the return transportation assembly, the material carrying disc moves from the first transportation assembly to the return transportation assembly, the second transportation assembly is lowered and communicated with the return transportation assembly, the material carrying disc moves from the return transportation assembly to the second transportation assembly, the second lifting assembly is lifted and communicated with the reversing table, and the material carrying disc moves from the second transportation assembly to the reversing table;

s4: and repeating the step S2 and the step S3, after the two sides of the material block in the material carrying disc are coated with films, driving the reversing table to rotate by the reversing driving element and communicating with the material discharging table, and moving the material carrying disc from the reversing table to the material discharging table through the material discharging transportation assembly and the reversing transportation assembly.

10. A plating method according to claim 9, wherein: in step S3, when the material loading tray is located in the first transportation assembly, the vision inspection device photographs and inspects the material blocks in the material loading tray to determine whether the material blocks are turned over, the grabbing assembly grabs the material blocks in the material loading tray, the rotary driving element drives the grabbing assembly to turn over the material blocks, and then the placing assembly puts the turned material blocks back into the material loading tray.
