Description
Technical field
It the utility model is related to the processing procedure field of OLED display device, more particularly to a kind of evaporation crucible.
Background technology
In FPD industry, AMOLED (Active-Matrix Organic Light Emitting Diode) displays
Device because its is frivolous, actively many merits such as luminous, quick response, wide viewing angle, colour gamut are wide, high brightness, low-power consumption, high-low temperature resistant and
Thinking most possible by industry turns into after liquid crystal display（LCD）Third generation Display Technique afterwards.
From a piece of big glass sheet become to need during showing motley displayer one by one by
One of essential processing procedure, that is, be deposited, the organic function layer and negative electrode in displayer are all by evaporation
Mode is deposited on backboard.The stability strong influence of evaporation process medium-rate the performance of display, while also for
Output of a factory has strong influence.Wherein crucible is a key factor of rate stabilization during influenceing to be deposited, wherein
The speed of subliming type material is most bad control.In general crucible, as subliming type material evaporates, meeting between material and crucible
Space is formed, material can not fully contact with crucible, it is easy to causes speed unstable, and easily causes material cracking.
Utility model content
For above-mentioned technical problem, the utility model provides one kind and can keep rate of heat addition stabilization, prevent material from sending out
The evaporation crucible of raw cracking.
In order to solve the above-mentioned technical problem, concrete scheme provided by the utility model is as follows：One kind evaporation crucible, including earthenware
Crucible body, the crucible body include the first sidewall of crucible and upper cover part, and the top center of the upper cover part is provided with a venthole, institute
State and be provided with moveable second sidewall of crucible on the inside of the first sidewall of crucible of crucible body.
Preferably, earthenware is improved filled with the packing material that thermal conductivity is good between first sidewall of crucible and the second sidewall of crucible
The heat-conducting effect of crucible body, reduce the temperature of crucible body.
Preferably, be provided with telescoping shoring column between second sidewall of crucible and the first sidewall of crucible, telescoping shoring column by
Shunk under the squeezing action of material, when material is reduced, telescoping shoring column struts, and promotes the second sidewall of crucible fully to be connect with material
Touch, keep the temperature of the rate of heat addition.
Preferably, spring is provided between second sidewall of crucible and the first sidewall of crucible, spring is in the extruding work by material
With lower contraction, when material is reduced, spring, which flicks, promotes the second sidewall of crucible fully to be contacted with material, keeps the temperature of the rate of heat addition
Degree.
Preferably, telescoping shoring column and spring, telescoping shoring column are provided between second sidewall of crucible and the first sidewall of crucible
Shunk with spring under the squeezing action of material, when material is reduced, telescoping shoring column and spring promote the second sidewall of crucible and material
Material fully contact, keep the temperature of the rate of heat addition.
Preferably, the telescoping shoring column and spring are the good metal material of thermal conductivity, improve leading for crucible body
Thermal effect.
It is further preferred that the material of first sidewall of crucible and the second sidewall of crucible is stainless steel, titanium or aluminium, crucible is improved
The heat-conducting effect of body.
Compared with prior art, the beneficial effects of the utility model are：By setting moveable second sidewall of crucible, the
Two sidewall of crucible can be mobile to crucible body centre with the reduction of OLED material so that OLED material can be with the second sidewall of crucible
It is always maintained at fully contacting, in this way, heating power does not have too big fluctuation, the temperature of crucible body will not also raise, and keep
The rate of heat addition can also prevent material from cracking occurs while stable.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Wherein, 1 is crucible body；2 be the first sidewall of crucible；3 be upper cover part；4 be the second sidewall of crucible；5 be telescoping shoring column；
6 be spring.
