Automatic wire feeding apparatus of evaporation system

Abstract

The invention discloses an automatic wire feeding apparatus of an evaporation system. The automatic wire feeding apparatus includes a vacuum support. A vacuum sealing end surface is installed on and connected to one end of the vacuum support and is matched with the end surface of the vacuum support to form vacuum status. A frequency-varying motor is arranged outside the vacuum support and the vacuum sealing end surface. A driving shaft is installed on and connected to the frequency-varying motor, passes through the vacuum sealing end surface and is disposed in the vacuum support. A wire feeding mechanism sleeves the driving shaft and is connected to an automatic wire feeding integrated controller which monitors thin film plating layer thickness and plating film linear velocity on line and can regulate the speed of the wire feeding mechanism. The automatic wire feeding apparatus of the evaporation system can automatically preset the plating layer thickness according to the thin film plating layer and preset Zn / Al ratio. When the plating layer thickness or the Zn / Al ratio is disqualified, the apparatus can regulates the speed of the wire feeding mechanism and then detects the parameters again until the parameters are qualified. Meanwhile, automatic wire feeding in the evaporation system is achieved.

Description

technical field [0001] The invention relates to the technical field of vacuum coating technology, in particular to an automatic wire feeding device for an evaporation system that can automatically detect thin film coating data and the like in an evaporation system. Background technique [0002] At present, in the traditional aluminum evaporation device, the aluminum wire feeding is basically driven by a motor, and the end of the aluminum wire is directly sent to the evaporation boat. The disadvantage of this structure is that the wire feeding is not accurate enough to ensure the aluminum wire. Accurately arrive on the evaporation boat for vaporization, which in turn affects the coating effect of vacuum coating. The "wire feeding mechanism" of the Chinese patent No. 201120333829.5 filed by the applicant in 2011 solves the above-mentioned technical defects. However, in the vacuum mechanism, the wire feeding mechanism can automatically feed the wire, and it can be measured and...

[0002] At present, in the traditional aluminum evaporation device, the wire feeding of aluminum basically uses a motor to drive the aluminum wire, and the end of the aluminum wire is directly sent to the evaporation boat. The disadvantage of this structure is that the wire feeding is not accurate enough to ensure that the aluminum wire Accurately reach the evaporation boat for gasification, which in turn affects the coating effect of vacuum coating

However, how to achieve the automatic wire feeding of the wire feeding mechanism in the vacuum mechanism, and to measure and detect the thickness of the coating layer and the ratio of zinc to aluminum, and to automatically adjust the speed of the wire feeding mechanism to make the coating meet the requirements. Not present, this technology is yet to be developed and improved
