Abstract

The invention discloses a net stretching device. The net stretching device comprises a bearing frame and a plurality of air floating assemblies, wherein the bearing frame has an installation surface;and the plurality of air floating assemblies are arranged on a mounting surface. Each air floating assembly comprises an air floating base fixed on the mounting surface, a bearing disc, an air hole and a limiting component, wherein the bearing disc is arranged on one side, deviating from the mounting surface, of the air floatation base, the bearing disc is provided with a first surface facing theair floatation base and a second surface arranged opposite to the first surface, and the second surface can bear a mask plate frame; the air hole is formed in the air floating base and faces the firstsurface of the bearing disc so that the bearing disc floats during air blowing; and the limiting component is connected between the air floatation base and the bearing disc, and the limiting component can limit a displaceable amount of the bearing disc in a direction parallel to the mounting surface. According to the net stretching device provided by the embodiment of the invention, air floatingsupport of the air floating assembly on the mask plate frame is more stable and reliable, and an air floating effect on the mask plate frame is improved.

Description

technical field [0001] The invention relates to the field of display panel manufacturing, in particular to a net stretching device. Background technique [0002] Organic Light-Emitting Diode (OLED) display panels are widely used in mobile phones, televisions, personal digital assistants, digital cameras, Various consumer electronic products such as notebook computers and desktop computers have become the mainstream of display devices. [0003] During the production process of the OLED display panel, organic materials need to be vapor-deposited on the substrate, and a fine metal mask (Fine Metal Mask, FMM) is usually required in the vapor deposition process. Before FMM is used, the mask strip needs to be welded on the mask frame, and this process needs to be carried out on the tensioning device. [0004] In the existing net stretching device, the mask frame is blown by air float balls or air float holes, so that the mask frame is floated. However, the method of blowing the...
