Surface treatment device and method for machining surface scratches on metal mask frame

Abstract

The invention discloses a surface treatment device and method for machining surface scratches on a metal mask frame. The following scheme is provided for solving the problems that the strength of grinding treatment is difficult to control through an artificial basic physical cleaning mode, secondary scratches can be caused to the opposite faces of a base plate and a mask, and consequently the product quality is affected. The surface treatment device comprises a bottom plate and a control system; an inserting groove is fixedly connected to the outer wall of the top of the bottom plate; an inserting plate is inserted in the inner wall of the inserting groove; inserting pipes distributed at equal intervals are arranged on the outer walls of the two sides of the inserting plate; cotton balls are inserted in the inserting pipes; and two supporting rods are fixedly connected to the outer wall of the top of the bottom plate. A drive fan evenly blows air to the surface of a metal mask frame body making contact with the cotton balls from an air outlet, the cotton balls are driven to conduct scratch treatment on the metal mask with proper strength, and secondary scratches of the metal mask frame body are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of limit devices, in particular to a surface treatment device for scratching the machined surface on a metal mask plate frame. Background technique [0002] At present, when the metal mask frame is used repeatedly, various equipment may cause different degrees of surface scratches on the metal mask frame, and outward burrs will appear at the scratches, which will affect the metal mask. The positioning accuracy of the stencil frame during installation affects the yield of evaporation products. [0003] Most of the existing surface treatment devices and methods for scratches on the machined surface of the metal mask frame simply clean up the scratches on the surface of the metal mask frame by manually using abrasive sand to wipe the basic cleaning method, and Such manual-based physical cleaning methods are difficult to control the strength of the polishing process, and the opposite surfaces of the substrate a...

AI Technical Summary

Problems solved by technology

[0004]Based on the existing surface treatment device and method for scratches on the machined surface on the metal mask frame, it is difficult to control the strength of the grinding treatment by the manual physical cleaning method. The opposite surface of the substrate and the mask plate will cause secondary scratches, thereby affecting the technical problem of the quality of the product. The invention proposes a surface treatment device for scratching the machined surface on the metal mask plate frame
