Problems solved by technology

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

Embodiment 1

[0051] Please refer to figure 1 and figure 2 , Embodiment 1 of the present invention is:

[0052] Please refer to figure 1 , a sorting device for mask strips, comprising a frame and a moving mechanism 1, the frame is provided with a mask carrier, the moving mechanism 1 is located above the mask carrier, and the mask carrier is close to the moving mechanism A mask strip packaging box is placed on one side of the mask strip 1, and more than two metal mask strips 2 are placed in the mask strip packaging box, and a dust-free Paper, dust-free paper is used to isolate the friction damage caused between two adjacent metal mask strips 2, and the side surface of the moving mechanism 1 close to the mask stage is connected with more than two adsorption mechanisms 3, the The adsorption mechanism 3 is configured to adsorb the metal mask strip 2 and the dust-free paper in the mask strip packaging box;

[0053] Please refer to figure 1 , the opposite ends of one side of the frame are r...

Embodiment 2

[0068] Please refer to image 3 and Figure 4 , the second embodiment of the present invention is:

[0069] Please refer to image 3 , a mask strip classification method, comprising the following steps:

[0070] Step S1, control the opening measuring mechanism 5 to measure the opening position 21 of the metal mask strip 2, and obtain the actual measurement coordinates; step S1 is specifically: control the opening measuring mechanism 5 to the metal mask strip 2 relative The opening positions 21 at the edges of both ends are measured to obtain actual measurement coordinates.

[0071] Step S2, calculating a measurement factor through the obtained actual measurement coordinates and the preset reference measurement coordinates;

[0072] Step S3, if the calculated measurement factor is greater than the preset specification value, then control the mask strip tension mechanism 4 to perform a tension operation on the metal mask strip 2; step S3 is specifically:

[0073] If the cal...

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...
