Liquid crystal supply unit 120 provides liquid crystal so that liquid crystal drop is added on the substrate 10 to nozzle 111.Can be by control module 150 control liquid crystal supply unit 120 to drip the liquid crystal of scheduled volume from nozzle.
The liquid crystal droplet defective may appear owing to the bubble in the liquid crystal that offers nozzle 111.For example, the drop defective can comprise: when not having liquid crystal drop to be added on the desired location of substrate 10 and the drip that produces; And the amount of drop is less than the liquid crystal droplet amount of expection.
The information about the defective of liquid crystal droplet that defects detection sensor 130 can be obtained offers control module 150.Control module 150 will be the defective locations of liquid crystal droplet and store this position receiving from defect detection unit 130 about nozzle 111 residing location recognition in the information of the defective of liquid crystal droplet.
In case finished the dropping of liquid crystal, repair sensor 140 and move to the position that defects detection sensor 130 detects the defective that drips liquid crystal, and judge whether liquid crystal droplet really has defective.Repairing sensor 140 can move under the control of the control module 150 of the defective locations that stores liquid crystal droplet.If liquid crystal droplet has defective, repair sensor 140 and calculate liquid crystal shortage amount.The information of liquid crystal shortage amount can offer control module 150.
Thereby control module 150 control liquid crystal supply unit 120 will be will be expelled to substrate 10 with the liquid crystal that is equated by the shortage amount of repairing sensor 140 calculating to nozzle 111 supply liquid crystal.In this course, control module 150 may command nozzles are to move to the position that Defects of Liquid occurs dripping.And, thereby control module 150 can be controlled liquid crystal drop feeder apparatus 100 all sidedly and with scheduled volume liquid crystal is applied on the substrate 10.
The example of application that below description is had the liquid crystal drop feeder apparatus 100 of said structure.
If produced the liquid crystal droplet with defective, for example the amount of drip or drop is less than desired amount, and when nozzle 111 was dripping liquid crystal, whether defects detection sensor 130 detects liquid crystal droplet had defective and the result is offered control module 150 so.Control module 150 confirm to have defective liquid crystal droplet the appearance position and store this position, and after liquid crystal is added dropwise to complete, will repair the position that sensor 140 controls to the liquid crystal droplet with defective.
As mentioned above, whether having the liquid crystal droplet with defective from detection is robotization to the process that reparation has the liquid crystal droplet of defective.Therefore, by these steps, whether exist liquid crystal droplet to compare by the situation that manual operation liquid crystal drop feeder apparatus is repaired the liquid crystal droplet with defective then with operating personnel according to oneself the visual examination of judging, do not need skilled operating personnel with defective.In addition, even as operating personnel not at the scene the time, thereby the liquid crystal droplet with defective is also repaired automatically and can successfully be carried out subsequent process.Therefore, can avoid the reduction of throughput rate.And under the situation of the amount that liquid crystal droplet occurs less than desired amount, operating personnel are difficult to check out how many amounts that lacked, thereby but can calculate liquid crystal shortage amount exactly can carry out the additional coating of suitable liquid crystal.Therefore, can easily repair liquid crystal droplet with defective.
Nozzle 111 can be installed on the nozzle erecting frame 112 of head unit 110 to move with respect to substrate 10.Head unit 110 is supported by a support unit 102, and 102 of support units are installed on the framework 101, thereby allows to move horizontally along a direction.In addition, head unit 110 is installed as and can moves along the horizontal direction vertical with the moving direction of a support unit 102.Therefore, the nozzle 111 that is installed on the head unit 110 can move with respect to substrate 10.
When expection forms a plurality of unit panels on the lower glass substrate on large-area and boosts productivity by having, a plurality of nozzles 111 can be set.Unit panel is corresponding to LCD panel that LCD adopted.A plurality of nozzles 111 are set to each unit panel and have at least one to drip liquid crystal.Therefore, can on a plurality of panels, form liquid crystal layer simultaneously, thereby can boost productivity.Liquid crystal supply unit 120 can comprise barrel 121 and pump module 122.Barrel 121 splendid attires will offer the liquid crystal of nozzle 111.Pump module 122 is configured to therefore make nozzle 111 can discharge liquid crystal providing discharge pressure to barrel 121 from barrel 121 when nozzle 111 is supplied liquid crystal.And pump module 122 has valve arrangement to open and/or to block liquid crystal flow between barrel 121 and the nozzle 111, makes and has only the liquid crystal of scheduled volume to be supplied to nozzle 111 from barrel 121.
In another embodiment, liquid crystal supply unit 120 can comprise air pressure supply rather than pump module 122.The air pressure supply to provide discharge pressure to liquid crystal, makes nozzle 111 can discharge liquid crystal to the predetermined air pressure of barrel 121 supply or gaseous tension.
When judging that the signal received has particular value---signal that this received for moving to from nozzle 111 position that drips liquid crystal the time be carved into the special time period of a certain predetermined instant and obtain, then light receiving unit 132 can be identified as this signal the signal that indication drips Defects of Liquid.
That is, as shown in Figure 3A, in the section, may between Optical Transmit Unit 131 and light receiving unit 132, not pass at the fixed time from the liquid crystal droplet of nozzle 111.Then, the light that sends from Optical Transmit Unit 131 directly advances to light receiving unit 132.Therefore, the received signal that obtains in the section at the fixed time has the particular value in range of tolerable variance.In this case, light receiving unit 132 judges that the signal that is received has steady state value and identify the drip that existence occurs when not generating liquid crystal droplet.
On the contrary, shown in Fig. 3 B, in the section, liquid crystal droplet may pass between Optical Transmit Unit 131 and light receiving unit 132 at the fixed time.So, thereby do not inject light receiving unit 132 from the liquid crystal droplet reflection that the light that Optical Transmit Unit 131 sends is being passed.Therefore, the signal value that obtained before or after passing between Optical Transmit Unit 131 and the light receiving unit 132 at liquid crystal droplet is with different at the signal value of the moment acquisition that liquid crystal droplet passes between Optical Transmit Unit 131 and light receiving unit 132.In this case, light receiving unit 132 identifies and has dripped liquid crystal.
The waveform of the received signal that in section at the fixed time, obtains and the waveform of reference signal not simultaneously, light receiving unit 132 can identify the defective that has the dropping liquid crystal.
In other words, when in the section at the fixed time from the amount of the liquid crystal droplet of nozzle less than or during greater than desired amount, the liquid crystal droplet with defective is different with the liquid crystal droplet with desired amount.Therefore, the waveform of the received signal relevant with the liquid crystal droplet that obtains by light receiving unit 132 with defective and with liquid crystal droplet with desired amount the waveform of relevant received signal different.
If judge that the received signal waveform is different with reference signal waveform, light receiving unit 132 will be identified as the liquid crystal droplet with defective corresponding to the liquid crystal droplet of received signal.And when the difference between judgement received signal waveform and the reference signal waveform exceeded range of tolerable variance, light receiving unit 132 identified two signal differences.Simultaneously, light receiving unit 132 only can be converted to the light that is received electric signal, and control module 150 then can comprise the signal processing unit of handling institute's electrical signal converted.
As mentioned above, therefore the signal that light receiving unit 132 processing are received because Optical Transmit Unit 131 is launched light can detect the liquid crystal droplet with defective in contactless mode to detect the defective that drips liquid crystal.Therefore, be not subjected to the influence of Defects of Liquid testing process from the liquid crystal droplet of nozzle 111 coatings.In other embodiments, defects detection sensor 130 can be configured to have the vision sensor of different contactless modes.
The anti-liquid crystal bottom that cover 136 is arranged at Optical Transmit Unit 131 and light receiving unit 132 of splashing, and have perforate 136a in the part corresponding with the bottom of nozzle 111.
Simultaneously, shown in Fig. 4 A, repairing sensor 140 can be vision sensor, and it obtains image at the EP place, position that detects the defective that drips liquid crystal, the image that is obtained is handled and judged whether really having generated the liquid crystal droplet with defective.When reparation sensor 140 detects drip, the liquid crystal shortage amount that it equates with the brilliant desired amount of a dropping liquid to control module 150 outputs.If control module 150 only detects drip after finishing the liquid crystal dropping, then control module 150 controls to nozzle 111 position EP and the coating of liquid crystalline drop that drip occurs.
When the liquid crystal droplet that has a defective when judgement is its amount less than the drop of desired amount or its amount greater than the drop of desired amount, repair the volume of sensor 140 from the image measurement drop that obtained.Repair 140 pairs of measured values of sensor and reference value then and compare, then this amount is outputed to control module 150 to obtain the shortage amount or the plussage of liquid crystal.Reference value is the volume of the drop of desired amount liquid crystal.
After drip or the drop of its amount less than the liquid crystal desired amount occurring, may residually there be liquid crystal the end of nozzle 111.In this case, residual liquid crystal may be coated with together with next drop, thereby the amount that causes drop is greater than the liquid crystal desired amount.Like this, when the amount that has drip or drop jointly less than the amount of liquid crystal desired amount and drop during greater than desired amount, after liquid crystal drop added, control module 150 was by comparing the liquid crystal shortage amount of calculating to the desired amount of liquid crystal and by the liquid crystal plussage being reflected to the short value that obtains of measuring of liquid crystal.
If control module 150 is judged the shortage that has liquid crystal, it controls to nozzle 111 amount that detects drip or the drop position less than desired amount, and control nozzle 111 has the drop of liquid crystal shortage amount with coating.
Repair 140 pairs of images that obtained of sensor and compare with previously stored image, and extract and be judged as uniform images, the liquid crystal shortage of the image that extracted of output is measured or the liquid crystal plussage then.
With reference to the image with liquid crystal droplet of desired amount, previously stored image has fixing liquid crystal shortage amount or liquid crystal plussage.In addition, when the difference between image that is obtained and the previously stored image is in range of tolerable variance, repairs sensor 140 and judge two image unanimities.Simultaneously, repair sensor 140 and only can obtain image, control module 150 then can comprise the graphics processing unit of the image that processing is obtained.
According to illustrative embodiments, can make from detecting the defective that drips liquid crystal to have the process automation of the liquid crystal droplet of defective to reparation.Therefore, do not need skilled operating personnel, even not at the scene the time, still can repair the defective that drips liquid crystal automatically operating personnel.Therefore, subsequent process can be successfully carried out, and the reduction of throughput rate can be prevented.
In addition, according to illustrative embodiments, when operating personnel's be difficult to the visual examination shortage how many amount of liquid crystal, can measure liquid crystal shortage amount exactly and can drip the liquid crystal of aequum.Therefore, can easily repair liquid crystal droplet with defective.
It will be apparent to those skilled in the art that under the situation that does not break away from spirit or scope of the present utility model, can carry out various remodeling and modification the utility model.Therefore, the utility model is intended to cover remodeling of the present utility model and the modification in the scope that falls into appended claims and equivalent thereof.
