The present invention is suppressed the OLED organic materials in distillation boat in advance in the before processing that distilled to OLED organic materials,
Consolidation sizing is allowed to, now organic material becomes fine and close, therefore will have more preferable heat-conducting effect, is advantageous to improve sublimation process
In heating rate, and can distillation boat in insert more organic materials, further improve distillation disposal ability；It is and close
Real material can also prevent material from being kicked up due to being evacuated with venting process, prevent product from being polluted by raw material.
Further improvement of the present invention is that the OLED luminous organic materials are powdered.
Further improvement of the present invention is that the compaction procedure is to suppress the organic hairs of OLED by a compression mould
Luminescent material, the OLED luminous organic materials consolidation is thereby set to shape.
Further improvement of the present invention is that by a surface there is the compacting tool set of concavo-convex cutting to suppress the OLED has
The powder of machine luminescent material, is allowed to form convex-concave surface.Concavo-convex surface can increase the surface area of organic material, improve distillation
Speed, while it is also beneficial to receive the heat radiation at top, be advantageous to the distillation in surfacing.
The present invention also provides a kind of distillation producing means of OLED luminous organic materials, and the distillation producing means includes：
Distil boat, for housing OLED luminous organic materials；Compacting tool set, have for suppressing the OLED in the distillation boat
Machine luminescent material；And distillation processing component, the OLED luminous organic materials for being shaped to the consolidation implement distillation processing.
Further improvement of the present invention is that the surface of the compacting tool set has concavo-convex cutting.
Further improvement of the present invention is that the distillation producing means includes a distillation boat base, the distillation boat bottom
Seat is provided with a storage tank for adapting to the distillation boat, and the distillation boat is placed in the storage tank.

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
Coordinate referring to shown in Fig. 1~Fig. 3, the distillation producing means of OLED luminous organic materials of the invention mainly includes rising
Magnificent boat base 1, distil boat 2, compacting tool set 3 and distillation processing component, wherein：
The surface of distillation boat base 1 caves inward to form a storage tank 11, and the storage tank 11 has one to adapt to the boat 2 that distils
Shape, in being handled in distillation house distillation boat 2；In embodiment, the storage tank 11 is a semicircle arcuation；
The boat 2 that distils is same in the present embodiment to have a half-circle-arc shape for coordinating the storage tank 11, and it is internally formed
There is cavity 21, for housing the powder of OLED luminous organic materials；
Compacting tool set 3 also coordinates distillation boat 2 to form the pressed surface 31 of a semicircle arcuation in the present embodiment, is used as this hair
Bright better embodiment, the pressed surface is formed with concavo-convex cutting 311.
Distillation processing component includes the heater for being placed in the bottom of distillation boat base 1 and the hot spoke for being placed in the top of distillation boat 2
Injection device, it mainly utilizes existing apparatus, therefore repeats no more its detailed configuration again.
Coordinate shown in Fig. 4 a~4c, OLED luminous organic materials are distilled in the distillation processing unit using the present invention
During processing, OLED luminous organic materials powder 4 is inserted in distillation boat 2 first, and the boat 2 that distils is placed in distillation boat base 1
In storage tank 11, the OLED luminous organic materials powder 4 in the distillation boat 2 is suppressed by the pressed surface 31 of compacting tool set 3,
Consolidation sizing is allowed to, and because the pressed surface 31 is formed with concavo-convex cutting 311, makes the luminous organic material powder after compacting
4 form convex-concave surface；Then heating sublimation processing is carried out to the luminous organic material powder 4 using the processing component that distils.
Effective effect that distillation processing is carried out using the inventive method is：
1st, after sublimation apparatus vacuumizes, heat conduction is slow in pipe.The heat transfer that luminous organic material 4 heats up mainly by bottom
Journey, next to that the heat radiation at top.After being suppressed, luminous organic material 4 becomes fine and close, therefore will have and preferably lead
Thermal effect, it is possible to increase heating rate.
2nd, secondly because the surface of luminous organic material 4 forms concaveconvex shape after compacting, it is beneficial to receive the heat at top
Radiation, be advantageous to the distillation in surfacing.
3rd, according to transcendental experience, material sublimation is initially since edge of materials, therefore after a period of time that distils, such as
Shown in Fig. 4 b, due to the presence of concavo-convex zigzag fashion, material will be made to be distributed to form many places edge.It can speed up the liter of material latter end
Magnificent speed.
4th, because luminous organic material 4 forms convex-concave surface after being pressed, therefore the surface area of material can be increased.By
In material sublimation be since surface, therefore its rate of sublimation also will improve.
5th, after compacting, luminous organic material 4 can improve the amount of filler due to more closely knit, further
Improve distillation machine disposal ability.Closely knit material can also prevent material from being kicked up due to being evacuated with venting process, prevent product quilt
Raw material is polluted.
Described above is only presently preferred embodiments of the present invention, not does any formal limitation to the present invention, though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any to be familiar with this professional technology people
Member, in the range of technical solution of the present invention is not departed from, when the technology contents using the disclosure above make a little change or repair
The equivalent embodiment for equivalent variations is adornd, as long as being the content without departing from technical solution of the present invention, the technology according to the present invention is real
