Problems solved by technology
[0006] However, the above-mentioned evaporation boat needs to apply a large voltage and current to it when the organic film is evaporated, so that it generates high temperature to melt and evaporate the material to be evaporated, which will lead to a rapid decrease in the service life of the evaporation boat. Speed up the replacement speed of evaporator boats
At the same time, when the evaporation boat working on high voltage and current is not in good contact with the electrode, it is very easy to damage the evaporation boat, thereby shortening the life of the evaporation boat, but the existing clamping device for the evaporation boat cannot solve the above defects

The invention provides an evaporation boat clamping device, which is applied to conducting and clamping an evaporation boat in vacuum coating equipment. The evaporation boat clamping device comprises an electrode piece and a pressing piece. A positioning groove is formed on the electrode piece; and a mounting end of the evaporation boat is accommodated in the positioning groove. The pressing piece and the electrode piece are pivoted and propped against the mounting end of the evaporation boat which is accommodated in the positioning groove. As the pressing piece and the electrode piece are pivoted and propped against the mounting end of the evaporation boat, when the evaporation boat needs to be replaced, only the pressing piece is pulled, so that the evaporation boat is conveniently, quickly and simply replaced. Meanwhile, as the positioning groove is formed on the electrode piece, the mounting end of the evaporation boat can be positioned on the electrode piece quickly and accurately, and the evaporation boat which is positioned on the electrode piece is clamped between the pressing piece and the electrode piece by means of the propping of the mounting end of the evaporation boat against the pressing piece. Therefore, the deflection of the evaporation boat is effectively prevented, so that the evaporation boat and the electrode piece are in good contact, and the service lifeof the evaporation boat is prolonged.
Description
technical field [0001] The invention relates to a clamping device, in particular to an evaporation boat clamping device suitable for conducting electricity and clamping an evaporation boat in the vacuum coating process of organic light emitting diodes. Background technique [0002] With the continuous advancement of science and technology and the continuous development of the economy, it provides a good platform for the development of electronic products, and promotes the development of electronic products towards the goal of high quality, high precision and high performance. Among them, OLED (English full name: Organic Light-Emitting Diode, Chinese name: Organic Light-Emitting Diode) is one of many electronic products. [0003] OLED has been widely used on display screens because of its lightness, lightness, power saving, etc., and has great market potential. At present, OLED applications in the world are focused on flat panel displays, because OLED is the only one that can...
