Description

Novel conveying equipment for vacuum film coating

Technical Field

The utility model relates to conveying equipment, in particular to novel conveying equipment for vacuum film coating.

Background

At present, traditional vacuum deposition equipment, as shown in fig. 1, including unreeling chamber, process chamber and the rolling chamber that sets gradually, unreel the intracavity and set gradually axle 1, axle 2, axle 3, the process intracavity is provided with the hot plate, and the rolling intracavity is provided with axle 4, axle 5, axle 6. Unwinding the film substrate from a shaft 1 of the unwinding cavity, and actively rotating a shaft 6 of the winding cavity to wind the film substrate; the film substrate is heated in the process cavity under the action of heat radiation of the heating plate, and meanwhile, reaction gas above the process cavity enters the process cavity to deposit the water-oxygen barrier film.

Disadvantages of conventional vacuum deposition apparatus: firstly, the traditional technology uses more driving rollers (such as shaft 2, shaft 3, shaft 4, shaft 5 in the figure) in the conveying process, wherein the shaft 5 is in direct contact with the barrier film layer deposited on the surface of the base material; excessive pressure or sliding friction can cause fatal damage to the membrane. Secondly, due to the friction action of the roller, the tension generated by the driving shaft cannot be well and uniformly distributed on each span of the film base material; the equipment provides tensioning tension through a driving shaft of the winding cavity, so that the film substrate is conveyed in an approximately horizontal state; but the tensioning tension is too large, so that the film has serious deformation and wrinkle generation; if the tension is reduced, the film substrate may be scratched due to its large span in the process chamber due to excessive gravity sag (as shown in fig. 2) and contact with the surface of the heating plate or other parts, which may result in fatal defects in both appearance and function of the product. And thirdly, when the film substrate passes through the upper part of the heating plate, the film substrate is heated through heat radiation (the substrate is not in direct contact with the heating plate), so that the substrate does not have good process temperature when entering the process cavity, and the performance of the initial film layer is influenced. The cause is as follows: firstly, the tension generated by the driving shaft cannot be well transmitted to the whole base material; secondly, the water-oxygen film on the upper surface of the base material can not undergo deformation and is influenced by friction; thirdly, the base material is heated by heat radiation, and certain temperature rise delay time exists.

Therefore, a new type of transfer apparatus for vacuum coating of thin films has been devised to solve the above problems.

It should be noted that the above background description is only for the sake of clarity and complete description of the technical solutions of the present invention and for the understanding of those skilled in the art. Such solutions are not considered to be known to the person skilled in the art merely because they have been set forth in the background section of the utility model.
