Description

Technical Field

[0001] The utility model relates to the technology of surface coating preparation, in particular to vacuum coating technology. Specifically, it is a vacuum connection isolation structure. Background Art

[0002] Vacuum coating is a commonly used surface coating treatment method. The product is loaded into the vacuum chamber. After the vacuum chamber is evacuated, the coating raw material enters, and the product surface is coated in a vacuum environment. However, in the current stage of vacuum coating, generally, a vacuum pumping device is directly connected to the vacuum chamber to work in real time to ensure the vacuum degree. Such a method has high energy consumption and leads to high vacuum coating costs.

[0003] Therefore, it is necessary to provide a vacuum section vacuum connection isolation structure to solve the above problems. Summary of the Utility Model

The connection main body is a square frame formed by butt-jointing four enclosing plates. An isolation plate is arranged inside the connection main body. The isolation plate is connected with an unfolding driving module, and sealing surfaces are arranged on the four enclosing plates corresponding to the isolation plate.

[0007] One end of the connection main body is connected to the vacuum chamber, and the other end is provided with a vacuum supply equipment connection body.

[0008] The isolation plate rotates 90° under the action of the unfolding driving module, and the vacuum supply equipment evacuates to form a vacuum guarantee structure fully unfolded before operation.

[0009] The isolation plate is driven to close the connection main body to form a vacuum isolation guarantee structure.

[0010] A vacuum detection sensor is arranged on the vacuum chamber. When the detection sensor detects that the vacuum degree is insufficient, it triggers the unfolding driving module to rotate the isolation plate by an angle A, and the vacuum supply equipment evacuates to form a detection-triggered real-time vacuum guarantee structure.

[0011] Further, the angle A is 5 - 12°.

[0012] Further, a sealing step part is arranged at the connection between the connection main body and the vacuum chamber, and the sealing step part is used as the setting area of the box body part sealing strip.

[0013] Further, the unfolding driving module includes a rotating shaft rotatably arranged on the connection main body. One end of the rotating shaft is connected to the isolation plate, and the other end is provided with a rotating gear, which is used in cooperation with a lifting rack.

[0014] Further, the lifting rack is connected to the lifting cylinder, and the lifting cylinder is arranged on the side surface of the connection body.

[0015] Further, the vacuum supply equipment connecting body includes a connection frame, and the connection frame includes a sealing press-fitting body.

[0016] Further, the connection body is provided with a sealing docking platform corresponding to the sealing press-fitting body, and a sealing gasket is arranged between the sealing docking platform and the sealing press-fitting body.

[0017] Further, after the sealing gasket is arranged between the sealing docking platform and the sealing press-fitting body, several bolt and nut modules surrounding the sealing docking platform are used to press-fit to form a sealing docking.

[0018] Compared with the prior art, the utility model reduces the operation energy consumption of the vacuum supply equipment and further reduces the cost of vacuum coating by detecting and triggering a real-time vacuum guarantee structure, and triggering the vacuum supply equipment to operate when vacuum extraction is required.
