Problems solved by technology

[0004] The above-mentioned prior art uses the tension force of the mesh to tension the metal mask. Not only is the operation very cumbersome, the preparation cycle is long, and the tension of the metal mask cannot be adjusted, it is easy to cause deformation of the evaporation hole due to excessive tension. Or shift, and it is easy to cause the metal mask to not be properly tensioned due to too small tension, which will affect the manufacturing accuracy and reduce the production quality of OLED products

Abstract

The invention relates to a metal mask plate tensioning machine, which comprises a tensioning device, wherein the tensioning device comprises a clamping mechanism used for clamping a metal mask plate, a horizontal adjustment mechanism and a tension adjustment mechanism; the clamping mechanism comprises a plurality of independent clamping sheets suitable for clamping the four edges of the metal mask plate; the horizontal adjustment mechanism is connected with the clamping mechanism and used for roughly adjusting the horizontal tension force of the metal mask plate; and the tension adjustment mechanism is arranged on the clamping mechanism and used for finely adjusting the horizontal tension force of the metal mask plate. According to the metal mask plate tensioning device, the metal mask plate can be accurately fixed and tensioned before being welded to a plate frame and cannot be deformed, so that the welding efficiency of the metal mask plate is effectively improved and the welding precision of the metal mask plate is improved, thereby improving the production quality of OLEDs (organic light emitting diodes).

Description

technical field [0001] The invention relates to the technical field of metal mask processing equipment, in particular to a metal mask tensioning machine. Background technique [0002] Organic electroluminescent devices have many advantages such as self-luminescence, fast response time, wide viewing angle, low cost, simple manufacturing process, good resolution and high brightness, and are considered to be the emerging application technology of the next generation of flat-panel displays. In OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) technology, metal mask processing technology is a very important and critical technology, and the precision level of this technology directly affects the quality and manufacturing cost of OLED products. [0003] The existing metal mask board needs to be welded to the board frame after the vapor deposition holes are processed before it can be put into use. At present, the method of welding the metal mask to the frame is to f...
