Mask strip classification equipment and mask strip classification method

Abstract

The invention relates to the technical field of mask strip classification, in particular to mask strip classification equipment and a mask strip classification method. The mask strip classification equipment comprises a rack and a moving mechanism, wherein a mask carrying table is arranged on the rack, the moving mechanism is located above the mask carrying table, a mask strip packaging box is placed on the side face, close to the moving mechanism, of the mask carrying table, two or more metal mask strips are placed in the mask strip packaging box, and dust-free paper is arranged between every two adjacent metal mask strips. Two or more adsorption mechanisms are connected to the side face, close to the mask carrying table, of the moving mechanism, mask strip tension mechanisms are arranged at the two opposite ends of one side face of the rack respectively, and an opening measuring mechanism is arranged on the side face, close to the mask carrying table, of the moving mechanism, so that stress deformation of a metal mask frame caused by metal mask strip net stretching contractility is reduced, the net stretching yield and the net stretching precision are improved, errors of the opening position are reduced, and therefore the problems of color mixing and the like of follow-up evaporation are solved.

Description

technical field [0001] The invention relates to the technical field of mask strip classification, in particular to a mask strip sorting device and a mask strip sorting method. Background technique [0002] The OLED display panel has the advantages of thin thickness, low power consumption, bendable and flexible display, and has become the development trend of the next generation panel display in recent years. [0003] Existing OLED panels use an evaporation source to heat and evaporate organic materials in a vacuum environment. The organic materials pass through the openings on the metal mask (Mask) to define the position where the film is formed on the glass substrate. The film-forming position must be the glass substrate. The specified light-emitting position on the glass substrate can effectively pass the current of the glass substrate into the OLED device to emit light, so the accuracy of the opening position of the metal mask is extremely important; and the accuracy of t...

This leads to a large difference between the actual tension value of each metal mask strip and the design value during the stretching process. If the actual tension of each metal mask strip is different, the shrinkage force of multiple metal mask strips If the sum cannot be offset with the CF design value, it will cause greater deformation of the metal mask frame, resulting in a shift in the opening position, which is one of the reasons for the low yield rate of the OLED screen.
