Abstract

The invention discloses an organic vacuum evaporation source which comprises a heating system, a cooling system, a temperature measuring system, a control system and a connecting component. Electric heating wires in the heating system are electrified for heating a metal heat conductor, and when a temperature reaches a vaporization temperature of an organic matter, the organic matter is evaporated to generate gas phase molecules; through rotation closing of a rotating baffle of the control system, the starting and stopping of a film coating process are realized; the cooling system is in a working state all the time, so as to avoid too high heating temperature and realize the effect of uniform heating of a crucible in a cavity of the metal heat conductor; a thermocouple wire of the temperature measuring system directly measures the temperature of the metal heat conductor, and then the heating temperature of the organic matter is fed back; and the reasonable connection of the connecting component ensures normal working of entire equipment.

Description

technical field [0001] The invention relates to the field of vacuum equipment, in particular to an organic vacuum evaporation source equipment. Background technique [0002] Vacuum coating technology originated in the 1930s, and it was not until the 1980s that industrialized mass production was formed. Vacuum coating is a method of heating the source of the film to be formed in the evaporator in a vacuum environment, making its atoms or molecules vaporize and escape from the surface, forming a vapor flow, incident on the substrate or the surface of the substrate, and solidifying to form a solid film. Vacuum coating technology is an important branch of vacuum application technology and the most promising surface coating application technology. It has a series of excellent characteristics that cannot be replaced by other processes: it is not affected by the material and shape of the coated component; Thickness can be controlled; functional surface coating can be plated. Comp...
