Plate middle part film coating vacuum film coating box

Abstract

The invention discloses a plate middle part film coating vacuum film coating box which comprises a main box body. A plurality of supporting legs are fixed to the bottom face of a base plate of the main box body. The side wall of a bottom transverse plate is fixed to the side walls of the multiple supporting legs. A lifting plate is inserted into the main box body in a sleeved mode. A lifting threaded sleeve is fixed to the middle of the bottom face of the lifting plate. The lifting threaded sleeve is inserted into a through hole formed in the middle of the base plate of the main box body in asleeved mode. A lifting threaded rod is connected to the lifting threaded sleeve in a sleeved mode. The bottom of the lifting threaded rod is hinged to the bottom transverse plate through a bearing. The bottom end of the lifting threaded rod extends out of the bottom face of the bottom transverse plate and is further fixedly connected with a drive gear. According to the plate middle part film coating vacuum film coating box, an upper cover body and a protective sleeve which can be repeatedly used are adopted for local coating, local film coating of workpieces to be processed is facilitated, repeated usage can be achieved, and the utilization rate is high; and meanwhile, the height of the lifting plate can be increased and decreased, the surface film coating requirement of the workpieces tobe processed of different heights can be met, and the using range is wide.

Description

technical field [0001] The invention relates to the technical field of vacuum coating equipment, in particular to a vacuum coating box for coating the middle part of a board. Background technique [0002] Vacuum coating is an important aspect in the field of vacuum applications. It is based on vacuum technology, uses physical or chemical methods, and absorbs a series of new technologies such as electron beams, molecular beams, ion beams, plasma beams, radio frequency and magnetron. Scientific research and practical production provide a new process for thin film preparation. [0003] However, some existing specific parts only need to be partially coated. At this time, the covering can only be fixed on the non-coating place, and the existing covering generally only has a one-time use effect and cannot be reused. At the same time, the height of the existing component fixing positions is fixed, which cannot be adjusted according to different heights of objects to be processed, ...
