The invention discloses a transmission mechanism for a vacuum coating production line, which includes an active assembly, a driven assembly and a magnetic coupler, the active assembly and the driven assembly are respectively arranged on both sides of the magnetic coupler, and the active assembly is driven by electricity , the movement of the active component is transmitted to the driven component through the magnetic coupling. Compared with the existing technology, the transmission mechanism uses a magnetic coupling to connect the driving shaft and the driven shaft, there is no direct contact between the driving shaft and the driven shaft, no mechanical transmission, reducing wear and tear, and the dynamic seal is converted into a static seal to maintain The airtightness of each chamber in each coating production line effectively prevents air leakage. The transmission mechanism has a simple structure, reduces energy consumption, saves resources, is convenient to use, prolongs service life, and improves safety, so its application prospects are very broad.
Description
technical field [0001] The invention relates to the field of a vacuum coating production line, in particular to a transmission mechanism for a vacuum coating production line. Background technique [0002] Vacuum coating technology first appeared in the 1930s, industrial applications began to appear in the 1940s and 1950s, and industrial mass production began in the 1980s. It has been widely used in electronics, aerospace, packaging, decoration, hot stamping and printing industries. Vacuum coating technology is a novel new technology of material synthesis and processing, and is an important part of the field of surface engineering technology. Vacuum coating technology is to use physical and chemical means to coat the solid surface with a layer of coating with special properties, so that the solid surface has wear resistance, high temperature resistance, corrosion resistance, oxidation resistance, radiation protection, electrical conductivity, magnetic conductivity, insulation...
