Description

Technical Field

[0001] The present invention relates to the technical field of roll coating, in particular to a composite multifunctional roll coating machine. Background Art

[0002] Vacuum coating machine mainly refers to a type of coating that needs to be carried out under a higher vacuum degree. There are many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy and PLD laser sputtering deposition. The main idea is to divide it into evaporation and sputtering. The coating of flexible materials is generally carried out on one side by a single method such as evaporation coating or sputtering coating. Evaporation coating is to heat and vaporize the coating material under a vacuum state to deposit the film. The coating speed is fast and the efficiency is high. Sputtering coating is to bombard the target material with glow discharge ionized gas to sputter out material particles to form a film layer. The coating has good stability, good uniformity and dense film layer.

[0003] As the application of roll-to-roll vacuum coating technology in emerging fields such as new energy power batteries becomes increasingly widespread, the size and weight of the rolls used in roll-to-roll coating machines are gradually expanding, so the roll-to-roll coating machines are getting bigger and taller, making the loading and unloading of rolls more and more time-consuming and labor-intensive, slowing down working time. At the same time, after the roll is loaded, it is necessary to manually unfold the roll in the sputtering channel. However, due to the small size of the existing roll-to-roll coating machines, the unfolding is troublesome and time-consuming, and the roll will be damaged over a large area during the unfolding process. In addition, during the vacuuming process of the existing roll-to-roll coating machines, some coating fragments will fall onto the surface of the coating drum, and when the machine body is opened, external air will carry dust into the interior, causing a certain impact on the coating.
