A device for nano-coating a mobile phone screen module

Abstract

This invention discloses a device for nano-coating mobile phone screen modules, including a lifting platform. A vacuum sealing machine is mounted on the upper side of the lifting platform. A first and second inlet / outlet slits are formed on the upper side of the lifting platform, with the first slit positioned above the second slit. A lifting plate is mounted on the inner side of the lifting platform, and a lifting structure is mounted on the lower side of the lifting plate. A first clamping block is fixedly connected to the surface of the lifting platform, and a second clamping block is positioned below the first clamping block. The first inlet / outlet slit is located between the first and second clamping blocks. A first sliding rod is fixedly connected to the upper side of the second clamping block. This invention uses a cylinder to move a wedge-shaped block, which, in conjunction with rollers, raises the second clamping block to hold the film material between the first and second clamping blocks. This allows the film material to be taut when the lifting plate lifts the mobile phone screen into the vacuum sealing machine, improving the vacuum sealing effect.
