Problems solved by technology

The friction will lead to an abnormal state that causes the mask plate to be picked and placed to vibrate greatly. In this abnormal state, the mask plate and the manipulator vibrate at the same time, which will affect the stability of the mask plate, and then affect the process. The pass rate of the display panel produced by evaporation of the mask plate

Abstract

The invention relates to a cassette which comprises a cassette main body, at least one neck used for placing a mask and arranged in the cassette main body and stopping blocks arranged around the neck(s) and used for limiting the two ends of the mask placed in the neck(s), wherein an included angle formed by the side surface of each stopping block at the at least one end of each neck, which is opposite to the mask, and the upper surface of the neck, is an obtuse angle. The invention also relates to the mask which comprises a mask frame, wherein concave parts are arranged at four corners of the mask frame; each of the concave parts is at least arranged at the position opposite to each of the stopping blocks of the cassette used for placing the mask; each of the concave part extends to the top surface of each of the stopping blocks, and the depth of each of the concave parts is increased gradually as the height of the frame is increased. When the cassette and the mask are used, in a process of picking and placing the mask by a mechanical arm, the jogging of the mask caused by the sagging of the mechanical arm is avoided.

Description

technical field [0001] The invention relates to the field of display panel manufacturing, and in particular to a mask clip and a mask. Background technique [0002] In the manufacturing process of Organic Light-Emitting Diode (OLED) display panels, OLED materials are usually evaporated to a low temperature by evaporation using a fine metal mask (Fine Metal Mask, FMM) according to a preset procedure. polysilicon (LowTemperature Poly-Silicon, LTPS) backplane. In the evaporation process, OLED materials such as red, green, and blue organic matter are evaporated onto specified positions on the backplane to form a display device using patterns on the FMM. [0003] Currently, in the manufacturing process of the display panel, a mask holder (Cassette, CST) is used to load and transfer the mask, and the mask is transported by a robot. [0004] figure 1 It is a schematic structural diagram of a mask clip in the related art. The mask clip includes a clip body and a plurality of slot...
