Mask, manufacturing method of mask and evaporation device

Abstract

The invention discloses a mask, a manufacturing method of the mask and an evaporation device. The mask comprises a mask frame and a mask bar, the mask frame has a first surface and a second surface, the first surface and the second surface are arranged relatively in the direction of the thickness of the mask frame, transition layer is arranged on the first surface; the mask bar is arranged on the mask frame and connected with the transition layer, and the texture of the transition layer is same with texture of the mask bar. According to the embodiment of the mask, the texture of the transition layer can be same with texture of the mask bar by arranging the transition layer on the mask frame. In the process of welding, two substances with the same texture can be welded together, so the mask bar can be welded on the mask frame conveniently and firmly, the difficulty of the welding is lowered, and the effect of the welding is improved, thus improving the quality of the mask, welding flaw make a difference to the service life of the mask is avoided effectively.

Description

technical field [0001] The invention relates to the field of evaporation technology, in particular to a mask, a method for manufacturing the mask, and an evaporation device. Background technique [0002] In the related art, the mask strips of the mask plate are usually welded to the mask frame by welding. However, the material and crystal structure of the mask strip and the mask frame are different, so welding is difficult and the welding effect is not good. At the same time, the use environment of the mask plate is high vacuum and high temperature, and it will be exposed to various organic substances, acids, alkalis and other substances during use. Welding defects greatly affect the service life of the mask plate. SUMMARY OF THE INVENTION [0003] The present application is made based on the inventor's discovery and recognition of the following facts and problems: the material and crystal structure of the mask strip and the mask frame are different, and welding is relativ...

Problems solved by technology

[0002] In the related art, the mask bars of the mask board are usually welded to the mask frame by welding. However, the material and crystal structure of the mask bar and the mask frame are different, so welding is difficult and the welding effect is not good.

At the same time, the use environment of the mask plate is high vacuum and high temperature, and it will be exposed to various organic substances, acids, alkalis and other substances during use. Welding defects greatly affect the service life of the mask plate
