[0003] Commonly used coating machines include vacuum boxes. The door panel of the vacuum box is generally equipped with an observation window. When coating according to actual production needs, the observation window needs to be blocked from the inside to prevent the observation window from being coated with a layer of film. Since the baffle is inside the vacuum box and the operation is outside, this puts forward requirements for the sealing of the vacuum box. Currently, dynamic sealing structures such as magnetic fluid seals and skeleton oil seals are mostly used. This structure has very high processing requirements and is prone to poor sealing, resulting in vacuum leakage. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-4 The magnetic baffle structure of an observation window for a high vacuum coating device is shown, which is installed on a door panel 700 of the high vacuum coating device, and includes:

[0024] The baffle seat 100 is mounted on the door panel 700 and is used to install the baffle shaft 200;

[0025] The baffle shaft 200 is installed in the cavity inside the baffle seat 100 to install the baffle 300 and drive it to rotate. It is rotatably installed in the air drop, with the front end connected to the baffle 300 and the rear end equipped with an internal magnetic block;

[0026] The baffle 300 is mounted on the front end of the baffle shaft 200 and blocks the observation window 701 by rotating;

[0027] The rotating handle 500 is sleeved on the baffle seat 100 and has an external magnetic block inside.

[0028] Specifically, a mounting slot is opened on the door panel 700, and the baffle seat 100 is fixed in the mounting slot by bolts. A sealing gasket is provided on the end face of the baffle seat 100. The middle part of the baffle seat 100 extends outward to form a boss, and a cavity is formed inside it. The baffle shaft 200 is extended into the cavity and arranged. The baffle shaft 200 is rotatably installed in the baffle seat 100 through a bearing 400. The baffle 300 is fixed to the front end of the baffle shaft 200 by bolts. The cross-section of the baffle shaft 200 is T-shaped, and the bearing 400 is sleeved in the middle of the baffle shaft 200. The rotating handle 500 is a circular knob-like structure with a cavity structure inside.

[0029] During operation, the rotating handle 500 is rotated, and due to the magnetic attraction between the outer magnet block 602 and the inner magnet block 202, the baffle shaft 200 is driven to rotate, thereby driving the rotation of the baffle 300, and realizing the opening and closing of the observation window 701 by the baffle 300; since the rotation operation process is realized by magnetic attraction, the operation area does not involve sealing issues, so the device can ensure sealing to the maximum extent.

[0030] Furthermore, an inner mounting hole 201 is formed at the rear end of the baffle shaft 200 , and the inner magnet block 202 is mounted in the inner mounting hole 201 .

[0031] Specifically, there are four inner mounting holes 201 corresponding to the four inner magnet blocks 202 , which are easy to install and maintain in the future and can be replaced according to usage.

[0032] Furthermore, a plurality of radial holes connected to the inner mounting hole 201 are formed on the outer periphery of the baffle shaft 200 , and fasteners for fixing the inner magnet block 202 are provided in the radial holes.

[0033] It should be noted that the fastener is a jackscrew, which is used to fix the inner magnet block 202 in the inner mounting hole 201, which is convenient and reliable.

[0034] Furthermore, a magnetic sleeve 600 is provided in the rotating handle 500 . A plurality of external mounting holes 601 are defined in the magnetic sleeve 600 . External magnet blocks 602 are mounted in the external mounting holes 601 .

[0035] Specifically, the magnetic sleeve 600 is also a cylindrical structure, with four external mounting holes 601, and four corresponding external magnet blocks 602 are installed inside the external mounting holes 601. The magnetic sleeve 600 is fixed in the rotating handle 500 by bolts.

[0036] Furthermore, a plurality of radial holes connected to the outer mounting hole 601 are opened on the outer periphery of the magnetic sleeve 600 , and fasteners for fixing the outer magnet block 602 are provided in the radial holes.

[0037] Furthermore, the fastener is a jackscrew, through which the outer magnet block 602 is fixed in the inner mounting hole 201, which is convenient and reliable.

[0038] The above embodiments are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
