The loading part is connected to a loading device 7 arranged on the side of the coating body 2, and the unloading part is connected to an unloading device 8 also arranged on the same side of the coating body 2.
[0030] Please also refer to Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, in this embodiment, the loop track 3 is a rectangular loop track, and four coating platforms 6 are respectively arranged in the rectangular loop track. The four coating platforms 6 respectively move in a cycle counterclockwise along the rectangular loop track. The loading section is located at the first position I in the lower right corner of the rectangular loop track, the unloading section is located at the fourth position IV in the lower left corner, the second position II is at the upper right corner, and the third position III is at the upper left corner. The coating platforms 6 on the slide base 4 and the bracket 5 move in a cycle from the first position I to the fourth position IV of the rectangular loop track under the action of the driving device.
