Abstract
A screen stretcher device is provided and has a tensioning mechanism, a first fixture and a second fixture. The first fixture is securely disposed at one end of a metal mask plate, and the second fixture is securely disposed at the other end of the metal mask plate. A horizontal plate is disposed above the metal mask plate. A measuring mechanism is configured to acquire location information of a pattern on the metal mask plate. A magnetic mechanism is disposed above the horizontal plate, and is configured to attract the metal mask plate such that the metal mask plate is deformed.
Claims13
A screen stretcher device configured to manufacture a metal mask plate for vapor deposition, wherein the screen stretcher device comprises:
- a tensioning mechanism comprising a first fixture and a second fixture disposed opposite to each other, the first fixture securely disposed at a first end of the metal mask plate, and the second fixture securely disposed at a second end of the metal mask plate opposite to the first end;
- a horizontal plate being liftable and disposed above the metal mask plate, wherein the horizontal plate is a metal plate, and a side of the horizontal plate facing the metal mask plate is a black oxidized surface;
- a measuring mechanism disposed in a working region of the screen stretcher device, the measuring mechanism configured to move three-dimensionally in the working region to acquire location information of a pattern on the metal mask plate;
- and
- a magnetic mechanism being liftable and disposed above the horizontal plate, and configured to attract the metal mask plate to deform the metal mask plate;
- wherein the measuring mechanism comprises an upper pattern acquisition device and a lower pattern acquisition device, the upper pattern acquisition device is located above the metal mask plate and is separate from the metal mask plate, and the lower pattern acquisition device is disposed below the metal mask plate and is separate from the metal mask plate.
