Vacuum film coating machine

Abstract

The invention discloses a vacuum film coating machine. The vacuum film coating machine comprises a control assembly and a vacuum chamber; a vacuumizing pump used for performing vacuumizing treatment on the vacuum chamber, a steam output port used for injecting metal steam into the vacuum chamber, and a rotary film coating device used for performing film coating treatment on a small panel are arranged in the vacuum chamber; the rotary film coating device comprises a discharging assembly, a clamping assembly used for driving the small panel to rotate, and a driving gear used for driving the clamping assembly to rotate; the clamping assembly is engaged with the driving gear, is arranged on the periphery of the discharging assembly and rotates around the discharging assembly; the vacuumizing pump is connected with the control assembly, and balanced film coating treatment can be performed on the two sides of the small panel; the situation that film coating of the small panel is not complete or not balanced can be avoided; and therefore the success rate of products is guaranteed, and effective production of the products is facilitated.

Description

technical field [0001] The invention relates to the field of vacuum coating equipment, in particular to a vacuum coating machine. Background technique [0002] In the traditional vacuum coating machine, when metal coating a small panel, the small panel is generally fixed in the vacuum coating machine. Under the discharge of the electrode wire, the metal vapor filled in the vacuum coating machine will be coated on the small panel. On top of this, the metal coating process is completed. However, in the traditional vacuum coating machine, since the positions of the small panel and the wire electrode are fixed, the coating efficiency on the side of the small panel facing the wire electrode is higher, while the side of the small panel facing away from the wire electrode is prone to Incomplete coating, or unbalanced coating will occur on small panels, which will reduce the success rate of the product and is not conducive to the effective production of the product.
