[0002] At present, the sublimation crystallization device of OLED organic materials on the market includes a glass quartz tube 201, a heating wire 202 located around the glass quartz tube 201, and an insulation layer 203 located outside the heating wire 202. The heating wire 202 is exposed to the air. It is easy to be oxidized, and the resistance of heating wire 202 becomes large, which affects the heating effect, and although there is an insulation layer 203 on the outside of heating wire 202 to keep warm, because heating wire 202 is in the air, the heat generated by heating wire 202 will be lost along with the air circulation. , the heating wire 202 is located outside the glass quartz tube 201, and the heating wire 202 heats the glass quartz tube 201 through thermal radiation, and the fluctuation of the external temperature will affect the heating effect

The invention relates to a sublimation crystallization device which comprises an outer pipe, a charging pipe located in the outer pipe and a receiving pipe. The outer pipe is provided with an exhaust port in the front end of the outer pipe. The outer pipe is in a vacuum environment through the exhaust port. The sublimation crystallization device further comprises a heat insulation layer covering the outer side of the outer pipe and a plurality of heating wires located in the outer pipe. The heating wires are located in the vacuum environment of the outer pipe. The heating wires will not be oxidized in the vacuum environment, the service life of the heating wires is prolonged, the heat environment emitted by the heating wires in the same current is higher compared with non-vacuum environment, power consumption is lowered, energy is saved, and the heating effect will not affected by the external environment due to the fact that the heat insulation layer directly covers the outer pipe.
Description
technical field [0001] The invention relates to a sublimation crystallization device, in particular to a sublimation crystallization device of OLED (organic light-emitting diode organic electric laser display) organic material. Background technique [0002] At present, the sublimation crystallization device of OLED organic materials on the market includes a glass quartz tube 201, a heating wire 202 located around the glass quartz tube 201, and an insulation layer 203 located outside the heating wire 202. The heating wire 202 is exposed to the air. It is easy to be oxidized, and the resistance of heating wire 202 becomes large, which affects the heating effect, and although there is an insulation layer 203 on the outside of heating wire 202 to keep warm, because heating wire 202 is in the air, the heat generated by heating wire 202 will be lost along with the air circulation. , the heating wire 202 is located outside the glass quartz tube 201, and the heating wire 202 heats t...
