Description

Crucible material amount detecting device, method and evaporator
Technical field
The present invention relates to the rete plated film field in display panel manufacturing processed, particularly relate to a kind of crucible material amount detecting device, a kind of crucible material quantity measuring method and a kind of evaporator with this crucible material amount detecting device.
Background technology
Still based on hot evaporation on current Organic Light Emitting Diode (OLED) establishment of component, and organic materials uses Organic Light Emitting Diode especially to make a upper great link, is not only significant cost ancestor, also concerns processing procedure quality.So in process of production, in the crucible of strict management and control evaporator, organic materials amount will be very important problem.
The existing evaporation source kind for hot evaporation process mainly comprises an evaporation source, concentrating type line evaporation source, single-point linear evaporation source and face evaporation source.For single-point line style evaporation source, as shown in Figure 1, comprise long strip shape body 10, have chamber in body 10, body 10 top arranges some nozzles 12, and body 10 lower center position is communicated with crucible 20.When to substrate 30 evaporated film, crucible 20 is by heating unit (being usually arranged at the both sides of crucible, not shown) heating, and the deposition material in crucible 20 is heated and is gasificated into the chamber that steam enters body 10, spray to substrate 30 through nozzle 12, plate thin film at the lower surface of substrate 30.
In prior art, the organic materials used due to hot evaporation is quite expensive, so the management and control of filler needs very strict, but also because of so, adds the pressure of processing procedure aspect.Often need the processing procedure (run) calculated instantly need fill out the material of quantity, and insert required amount.But it is still surplus how many on earth during the course because the quantity of material in crucible cannot be known exactly.Therefore sometimes just because burning no material and produce the serious variation of product performance.Current used material control and management method has the following two kinds.
The first first calculates the basic consumption of corresponding deposition (DEPO rate), then see how long this processing procedure needs, and estimates that material need consume total amount, inserts quantity of material needed for determining afterwards again.Such as: when deposition (DEPO rate) is for 1A/sec, corresponding basic consumption is 2g/hr.If this processing procedure (run) needs 144hrs consuming time, then need consumption material total amount to be about 2*144=288g, then the quantity of material that this processing procedure is inserted need the amount of being greater than 288 grams.
The second is, quantity of material control is carried out in collocation deposition monitoring sensor (DEPO rate monitor sensor).But this method, once find the numerical value (rate value) of deposition, toward declining, depositing temperature is constantly toward rising, and as shown in Figure 2, the material now in crucible consumes end.
In addition, filler keyholed back plate gimmick preceding method one matching method two use often used at present, occurs, though this kind of judgment mode may know that material consumes end once run into the abnormal conditions of picture shown in Fig. 2, but unusual phenomenon there occurs, so product will be caused abnormal.
So how just can know before material deterioration inside is complete, will keep being considerable problem to processing procedure management and control and product.Therefore, need to design the device that precisely can detect remaining quantity of material in crucible.

Wherein, the sense data that multiple piezoelectric transducers 3 that the effect of data receipt unit is used to receive Weighing module are sent.The data receipt unit of computing module both can be connected by wired mode of connection with each piezoelectric transducer 3 of Weighing module, also can obtain sense data by the mode of transmission over radio.After receiving the sense data of piezoelectric transducer 3, sense data is sent to sum unit process by data receipt unit.
Sum unit, each sense data transmitted by data receipt unit adds up, and first calculates the weight of crucible 2, then deducts crucible 2 and conduct oneself with dignity, obtain the surplus material amount in crucible 2.The surplus material amount drawn, then be transferred to numerical value output unit.
Numerical value output unit, then the numerical value of the surplus material amount transmitted by sum unit, sends control module to, to determine whether send corresponding steering order by judging.
Three, control module
The control module of the crucible material amount detecting device of the embodiment of the present invention, surplus material amount for the surplus material amount with setting that computing module are calculated gained compares, when the surplus material amount calculating gained is less than the surplus material amount of setting, send a steering order.
The crucible material amount detecting device of the embodiment of the present invention, the steering order sent, can be the instruction stopping heating crucible 2, or stops the instruction of evaporation processing procedure, or send the instruction of the information warning stopping heating, with the change reminding operator to pay close attention to surplus material amount in crucible 2.According to different practical situation, different steering orders can be determined.Also can the quantity of material in crucible when being in different levels, successively send different steering orders, such as, first carry out the instruction warned, then send the instruction stopping heating.
Concrete, as shown in Figure 7, the crucible material amount detecting device of the embodiment of the present invention, its control module comprises numerical value receiving element, sum unit, instruction generation unit and instruction output unit, and each unit is described below:
Numerical value receiving element, the surplus material numerical quantity in the crucible 2 that the numerical value output unit receiving computing module is sent, sends comparing unit to;
Comparing unit, the surplus material amount of surplus material numerical quantity with the setting stored in advance compared, the surplus material value of setting mentioned here, can be more than one; More than one time, can one of them be that correspondence sends the stop value stopping heating signal, also have the corresponding warning value sending information warning, the residue doses (such as 10 grams) in the crucible that warning value is corresponding, is greater than the residue doses (such as 5 grams) in the crucible corresponding to stop value.
The surplus material amount of setting, can be stored in advance in a storage unit of control module, call in order to comparing unit.
Instruction generation unit, its effect is the comparative result that reception comparing unit transmits, if the surplus material numerical quantity of gained is less than the surplus material amount of setting after testing, then generates corresponding steering order; If surplus material amount is not less than the surplus material amount of setting, then do not generate steering order, proceed real-time detection by piezoelectric transducer.
Instruction output unit, its effect is the controller steering order that instruction generation unit generates being exported to evaporator, to realize the action stopping heating crucible, or stops the action of evaporation processing procedure, or sends the action of the information warning stopping heating.
The evaporator of the embodiment of the present invention, after its controller receives the steering order of instruction output unit output, by the control of controller, realize the action stopping heating crucible, or stop the action of current evaporation processing procedure, or send the action of information warning stopping heating, thus the variation avoiding the product performance that produces because burning no material in crucible serious.
Introduce the crucible material quantity measuring method of the embodiment of the present invention below again, the identical or corresponding feature mentioned in a device, when introduction method, repeats no more.
As shown in Figure 8, the crucible material quantity measuring method of the embodiment of the present invention, mainly comprises step S1-step S3.
Step S1 is the sense data being gathered crucible 2 weight by the multiple piezoelectric transducers 3 be arranged at bottom crucible 2;
