Vacuum coating system

Abstract

The invention provides a vacuum coating system which comprises a coating device, a transfer device and at least one suspension operation device which are sequentially connected, and the coating device is provided with a coating cavity, a rotary workpiece disc, a workpiece disc driving mechanism, an ion source, a workpiece disc supporting flange and an evaporation source; the suspension operation device comprises a suspension cavity, a cage frame arranged in the suspension cavity and a cage frame driving mechanism; the transfer device comprises a transfer cavity, a manipulator and a reversing guide rail; the transfer device is used for connecting the coating device and the suspension operation device; and during exchange operation, the coating device, the transfer device and the suspension operation device are all in a vacuum state. The device is convenient to mount and debug, low in failure rate, flexible in manipulator control and high in coating efficiency.

Description

technical field [0001] The application relates to the field of optical technology coating, in particular to a vacuum coating system. Background technique [0002] In the field of optical technology coating, improving the coating efficiency, reducing the failure rate of the coating system, and making the system maintenance more convenient has always been the goal pursued in the field of vacuum coating technology. [0003] Figure 1 to Figure 6 shows a current coating system such as Figure 1 to Figure 6 As shown, the coating system mainly includes a process chamber 1 and a transport chamber 2, which are separated by a valve 4 in the middle. [0004] Several ion sources 5 and sputtering sources 6 and other equipment are arranged around the process chamber 1, which are used to coat various film materials on the hanging plate 10 of the fixed substrate, and there are process chamber turrets 7 and hanging plates 10 inside the process chamber. , the turret 7 is driven by the top m...

AI Technical Summary

Problems solved by technology

[0005] 1. The processing requirements of the parts are high, the installation is difficult, and it is difficult to ensure that the process chamber, the manipulator chamber and the cage door are at the same horizontal position;

[0006] 2. It is inconvenient to maintain, and it is difficult to find the specific reason for the problem;

[0007] 3. The failure rate is high, the accuracy of picking and placing the hanging board is high, the overall strength is greatly affected by vacuum and temperature during use, and the probability of problems is high;

[0008] 4. The efficiency is low. After the process chamber fails, there is a high probability that it needs to break the vacuum to solve it, which delays the process time
