Problems solved by technology

However, the efficiency of this method to increase the temperature of the evaporation nozzle is very low, and it takes a long time to heat up, so it often takes several hours to solve the plugging phenomenon with this method, which takes a long time
[0005] Another solution is to dredge the evaporation nozzle through the mechanical struct

Abstract

The invention provides an evaporation device, which comprises an evaporating source and an electromagnetic induction heater. The evaporating source is provided with a shell and a plurality of evaporating nozzles arranged at the top of the shell; and the electromagnetic induction heater is used for heating the evaporating nozzles, and arranged to have the adjustable distance relative to the evaporating nozzles. By adopting the electromagnetic induction heater, vortexes are generated in the evaporating nozzles and quickly heated, blocked materials are evaporated, and the phenomenon that the evaporating nozzles are blocked in the evaporating process of the organic materials can be conveniently avoided.

Description

technical field [0001] The present invention generally relates to the field of evaporation, in particular to an evaporation device. Background technique [0002] At present, the organic evaporation source used in the evaporation of large-sized organic light-emitting diodes (OLEDs) is a line source. Generally, the configuration of the evaporation source is roughly the shell with the evaporation nozzle, the inner crucible, and the materials in the crucible from the outside to the inside. [0003] During the evaporation process, the material in the crucible is evaporated at high temperature, comes out from the gap at the top of the crucible, and then comes out through the evaporation nozzle, and then evaporated onto the glass substrate. Once the hole is blocked, the organic material will block the entire evaporation nozzle, so that the material cannot be completely evaporated. [0004] The traditional solution is to install a heating wire near the evaporation nozzle, and incr...
