Embodiment Construction

[0007] In order to make those skilled in the art more clearly understand the technical solution of the glass coating equipment and the magnetic fluid sealing device of the present invention, the specific implementation manner thereof will be described below with reference to the accompanying drawings.

[0008] Ferrofluids are also known as ferrofluids, ferrofluids, or ferrofluids. It combines the properties of magnetic materials and liquids with the ability to use magnetic fields to control rheological, thermophysical, and optical properties. It is a colloidal solution formed by highly dispersing ultrafine magnetic particles in a carrier liquid through a surfactant.

[0009] refer to figure 1 , the magnetic fluid sealing device 1 for glass coating equipment of the present invention, which includes an outer jacket 2, a micro screw 3, an inner shaft 4, a medium screw 5 and a magnetic fluid 6, the magnetic fluid includes magnetic powder and a surfactant, and 4 sets of inner shaf...

Abstract

The invention discloses glass coating equipment. The glass coating equipment comprises a coating chamber, a vacuum conversion chamber, a target and a magnetic fluid sealing device; the magnetic fluid sealing device comprises an outer sleeve, a micro screw, an inner shaft, a medium screw and magnetic fluid; the magnetic fluid comprises magnetic powder and interface active agent; the inner shaft is sleeved in the outer sleeve and axially parallel to the outer sleeve; the inner shaft and the outer sleeve are connected and fixed by the micro screw and the medium screw; a clearance is formed between the inner shaft and the outer sleeve; and the magnetic fluid is filled in the clearance between the inner shaft and the outer sleeve. The equipment effectively solves the problems that the vacuum sealing device in the conventional glass coating equipment is easily aged and deformed and leaks air and the like, and realizes high sealing of the target in the glass coating equipment.

Description

technical field [0001] The invention relates to a glass coating device and a sealing device. Background technique [0002] At present, glass coating equipment has been widely used, and the vacuum sealing device is a very important part. However, in domestic and foreign glass coating equipment, the sealing form of fluorine rubber ring oil seal is usually used. However, due to the limitation of the material properties of rubber products, this sealing method has the following disadvantages: First, the rubber products will gradually age and become brittle after long-term storage under normal temperature and pressure. Secondly, because the rubber ring must be in a compressed state to perform its function, and when the rubber ring is in a long-term compressed state, permanent deformation or residual deformation will occur, which directly affects the sealing effect. In addition, after the oil seal is immersed in the sealing oil, the affinity of rubber molecules and oil will make ...
