Vacuum coating device, vacuum double-sided coating device and position regulating method for belts

Abstract

The invention discloses a vacuum coating device for metal belts, a vacuum double-sided coating device for metal belts, and a position regulating method for metal belts in the vacuum coating device. The vacuum coating device comprises a vacuum coating chamber, wherein the input end of the vacuum coating chamber is provided with an input end roller (11) and an input clamping roller set (13); the output end of the vacuum coating chamber is provided with an output end roller (12) and an output clamping roller set (14); the metal belts are clamped by the input clamping roller set (13) for being conveyed forwards, pass through the input end roller and the output end roller, and are clamped by the output clamping roller set for being pulled forwards; the metal belts between the input end roller and the output end roller are partly in a hanging chain state or are partly in a similar hanging chain state. The vacuum coating device disclosed by the invention can prevent the metal belts from deformation and defects in a coating process while carrying out coating operation.

Description

technical field [0001] The invention relates to the field of vacuum coating, in particular to a vacuum coating device for metal strips. In addition, the invention also relates to a vacuum double-sided coating device for metal strips and a method for adjusting the position of the metal strips. Background technique [0002] Vacuum coating is a process in which the target material isolated by the heating source is hit on the surface of the object to be plated in the vacuum chamber. [0003] The vacuum coating of common metal strips usually includes: the metal strip released from the unwinding machine in the atmospheric environment passes through several horizontally arranged vacuum chambers (such as sealed air locks at all levels, various vacuum preparation chambers, various vacuum evaporation chambers, etc.) ) connected in series to form a series of vacuum chambers, and zinc, zinc alloy, stainless steel and other materials are plated on the metal strip. After the metal strip ...

AI Technical Summary

Problems solved by technology

Since it is impossible to adjust the clamping roller groups in the vacuum chamber to be completely parallel, when the metal strip passes through each clamping roller group, it is compressed and deformed by the clamping force between the idler roller and the nip roller, thus passing through the vacuum chamber. After stringing, various defects (such as saber bends, ruffles, etc.) appear on the metal strip, which reduces the yield rate of vacuum coating on the metal strip
