The evaporation source device for evaporator provided by the invention comprises a crucible; the crucible slot of the crucible is provided with at least one first conductive clapboard along a first direction, and each of the first conductive clapboard is connected with the crucible wall; and the crucible slot is provided with at least one second conductive clapboard fixedly connected with the first conductive clapboard along a second direction, and each of the second conductive clapboard is connected with the crucible wall. The technical scheme provided by the invention can shorten the heat transfer path in an evaporation material, realize even transfer of heat in the evaporation material, and further improve the thermal stability of the organic material evaporation, thereby maintaining stability of plating rate and improving the yield rate of the organic material evaporation.

Description

technical field [0001] The invention relates to the technical field of evaporation equipment, in particular to an evaporation source device of an evaporation machine and an evaporation machine. Background technique [0002] Organic Light-Emitting Diode (OLED for short) manufactures a carrier transport layer and an organic light-emitting layer constituting an OLED display device by evaporating organic materials. The evaporation sources of today's OLED evaporation machines are divided into point source evaporation sources and linear evaporation sources. Since linear evaporation sources can improve the utilization rate of evaporation materials and the uniformity of film formation, linear evaporation sources are regarded as a research hotspot. There is widespread concern. The organic evaporation materials evaporated in the evaporation source device are mainly divided into two types, one is sublimation organic materials, and the other is melting organic materials. Among them, t...

Problems solved by technology

[0003] like figure 1 As shown, the evaporation source device of the existing OLED vapor deposition machine includes a crucible 1 containing organic materials, and the crucible 1 is heated to realize the evaporation of the organic materials in the crucible 1. Since the heating of the crucible 1 is only the 1 around the crucible wall for heating, the structure of the crucible 1 is generally figure 1 The long strip shape shown, therefore, for the organic material in the crucible groove of the crucible 1, the thermal conductivity of the organic material itself is poor, and the heat conduction path is long, which is easy to cause uneven heat transfer, especially for large-scale evaporation As far as the source is concerned, the phenomenon of uneven temperature distribution is more obvious, which in turn causes problems such as insufficient stability of the deposition rate of the evaporation of organic materials and a decrease in yield.
