Problems solved by technology

However, the cathode device is affected by its own dimensional accuracy and strong magnetic attraction, especially during installation, the assembly accuracy is difficult to meet the design accuracy requirements
Chinese patent CN201778106U discloses a rectangular planar magnetron cathode structure in vacuum coating equipment. This cathode structure solves the above problems to a certain extent, but its target utilization rate still cannot achieve a qualitative leap
Chinese patent CN201770767U discloses a vacuum coating cathode device. The main technical problem solved by this patent is to simplify the process of replacing the target, save the time required for replacing the target, and does not solve the technical problem of low target utilization.
Chinese patent CN201981253U discloses a rectangular planar magnetron sputtering cathode. For the shortcomings of the sputtering cathode with an anode frame, the anode frame is canceled and the structure is simplified; in addition, the structure of the shield is improved to avoid the problem of grounding of the shield ; The improvement of the planar cathode still fails to increase the utilization rate of the target
However, because the signals of the substrate entering and exiting cannot be accurately received, and the human-controlled action has a certain delay, it is usually impossible to open the inlet and outlet gate valves in a timely manner, which reduces production efficiency.
In addition, the vacuum coating production line has very high requirements on the vacuum environment, so the thickness of the door body of the vacuum chamber will increase. Correspondingly, the thickness of the gate valves at the entrance and exit of the production line will increase, and the difficulty of manual operation will increase.
[0004] With the rapid development of coating technology in the field of vacuum coating, the requirements for coating products are getting higher and higher. Therefore, more and more improvements have occurred in the coating production line, and the requirements of the production line have increased accordingly. The overall stability of the coating production line in the prior art stability and coating uniformity, low production efficiency and high equipment cost; and most of the existing coating production lines can only meet the coating of one target material, or the entire production line is only suitable for one type of target material, which cannot meet the current requirements. Therefore, there is an urgent need for a coating production line that can adapt to a variety of targets and the entire coating process is easy to operate

Abstract

The invention discloses a vacuum coating production line, which includes a transfer line and a coating line, the coating line is connected to the transfer line; the transfer line includes a track, at least one transfer car and at least one film loading device, and the transfer car runs on the track , convey the film loading device through the transfer car; the coating line includes an inlet chamber, an inlet transition chamber, an inlet buffer chamber, a coating chamber, an outlet buffer chamber, an outlet transition chamber and an outlet chamber . Compared with the existing technology, the transmission line and the coating line are connected end to end to form a circular line, which saves floor space. The substrate transmission in the entire coating production line adopts intelligent control, which saves manpower and material resources and improves production efficiency. Each chamber in the coating line is based on Product demand is replaced or increased, and the entire coating production line adapts to various coating process requirements, prolongs the service life, and saves resources, so its application prospects are very broad.

Description

technical field [0001] The invention relates to the technical field of vacuum coating, in particular to 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.
