Problems solved by technology

[0006] 1. The method of tearing usually produces burrs or flashes, which leads to the uneven surface of the mask plate, which affects the use of subsequent processes and reduces the yield of the evaporation process.
[0007] 2. Due to the existence of the half-score line, the half-score line may be torn during the stretching and flattening process of the metal sheet, resulting in scrapping

Abstract

The invention provides a manufacturing method of an OLED (Organic Light Emitting Diode) metal mask plate. The manufacturing method comprises the following steps: carrying out pattern transfer and chemical etching on a metal sheet by photochemical etching to manufacture a prefabricated template; machining the metal sheet by using a numerically controlled machine tool to manufacture a frame; further machining the prefabricated template and the frame by using a laser welding machine, wherein the laser welding machine is provided with a laser welding head and a laser cutting head, and the frame is fixed on a welding platform of the laser welding machine; putting the prefabricated template on the frame, tightly pressing by a pressing device, and welding and cutting the prefabricated template and the frame by using the laser welding head and the laser cutting head. In addition, a control file is edited according to motion paths of the laser welding head and the laser cutting head to automatically finish welding and cutting. According to the manufacturing method of the OLED metal mask plate, the metal mask plate is manufactured by laser welding and cutting, so that the quality of a product is well ensured, the problems of burrs, trimmings and the like are avoided, and convenience is provided for use of a subsequent evaporation process.

Description

technical field [0001] The invention relates to a method for manufacturing an OLED metal mask plate. Background technique [0002] OLED (Organic Light Emitting Diode) is a display technology with self-luminous characteristics. Compared with the widely used LCD (Liquid Crystal Display) display technology, it has the advantages of large viewing angle, bright colors, and low power consumption. Therefore, it will gradually Replace the current mainstream liquid crystal display technology. In the OLED display manufacturing process, there is an organic luminous body evaporation process, which needs to use high-precision OLED Metal Mask (organic light-emitting diode high-precision metal mask plate) as an evaporation template. The quality of OLED Metal Mask has a great impact on the quality of the display Quality and yield have a great impact. In the OLED display industry, OLED Metal Mask is a key factor restricting the development of OLED screens. [0003] The typical structure of...
