After the coating is completed, the unloading device unloads the coated substrate, and the operation is cyclically repeated. The present invention has a novel structure and a clever design, improves work efficiency, has a high degree of automation, reduces labor costs, and improves product quality.

[0039] The working principle of the present invention is as follows: the substrate loading device loads the substrate onto the lower suction cup device, the lower suction cup device sucks the substrate, and after the cutting mechanism slices the covering film, the upper suction cup device sucks the sliced ​​covering film and stretches and initially positions the covering film, and transfers it to the lower suction cup device, aligns the covering film and the substrate, and then bonds them together; the unloading device unloads the covering film and the substrate after bonding.
