Abstract

The invention discloses a net stretching device. The net tensioning device includes: a bearing frame with a mounting surface; and a plurality of air flotation components arranged on the mounting surface, and each air flotation component includes: an air flotation base fixed on the mounting surface; On one side of the installation surface, the supporting tray has a first surface facing the air-floating base and a second surface opposite to the first surface, the second surface can support the mask frame; air holes, the air holes are arranged on the air-floating base And set towards the first surface of the supporting tray, so that the supporting tray is floated when blowing air; and the limiting part is connected between the air floating base and the supporting tray, and the limiting part can limit the supporting tray in the direction parallel to the installation surface The amount of displacement on . According to the net stretching device of the embodiment of the present invention, the air bearing support of the mask frame by the air bearing component is more stable and reliable, and the air bearing effect on the mask 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...
