Metal mask strip fixture and metal mask preparation device

Abstract

The invention relates to the technical field of display, and discloses a metal mask strip fixture and a metal mask preparation device. The metal mask strip fixture comprises a fixture body, wherein the fixture body comprises a fixture lower jaw, a connecting rod which is fixedly connected to the fixture lower jaw and a fixture upper jaw which is hinged to the connecting rod, and the fixture upper jaw and the fixture lower jaw form a containing space for containing a metal mask strip; the fixture lower jaw comprises a clamping part and an adjusting part, the clamping part is opposite to the fixture upper jaw, the adjusting part is located on one side of the clamping part along the direction close to the clamping part and far from the clamping part, and the distance between the adjusting part and the surface of the fixture upper jaw as well as the fixture upper jaw and the surface of the fixture lower jaw is gradually increased; and the adjusting part is used for adjusting the bending state of the metal mask strip. According to the metal mask strip fixture, the adjusting part is used for adjusting the state of the hanging part of the metal mask strip, so that the metal mask strip is extended from the bending state, and the clamping effect and the welding effect of the metal mask strip are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a metal mask bar fixture and a metal mask preparation device. Background technique [0002] The existing OLED evaporation technology is to volatilize the organic evaporation material through high temperature heating, so that the volatilized material is evaporated on the back glass through the effective evaporation opening of the metal mask strip, thereby realizing organic light emission. Among them, such as figure 1 As shown, the metal mask strip 11 containing effective evaporation openings is welded to the surface shown in the frame 12 after adjusting the key parameters to meet the design requirements by stretching the jig. When welding, such as figure 2 As shown, the metal mask strip 11 is placed on the surface of the net tensioner loading machine 21, the clamp body 22 advances from position a to position b, and the stretching and clamping area of ​​the metal mask strip 11 ...

AI Technical Summary

Problems solved by technology

[0003] However, if image 3 As shown, the metal mask strip 11 of some products has a large amount of sag in the clamping edge area, and there is a case of bending

In this case, when the clamp body 22 advances from position a to position b, the curved area of ​​the metal mask strip 11 overlaps with the lower jaw 23 of the clamp. At this time, the downward engagement of the upper jaw 24 of the clamp will cause the metal mask strip 11 Clamping and breaking seriously affects the parameter adjustment and welding of the metal mask strip 11, resulting in waste of the metal mask strip 11
