Background technology
Light-emitting diode (Light Emitting Diode, LED) is a kind of optoelectronic semiconductor component that current conversion can be become particular range of wavelengths.Light-emitting diode is high with its brightness, operating voltage is low, power consumption is little, easily with the integrated circuit coupling, drive the advantages such as simple, life-span length, thereby can be used as light source and be widely used in lighting field.
Generally speaking, need light-emitting diode be placed to desired position such as light fixture or other optical elements by the method for piece medium.General piece method arranges a suction nozzle above light-emitting diode, then draw light-emitting diode and it is placed to the desired position by suction nozzle.Simultaneously, below light-emitting diode or other positions have an image sensor position of light-emitting diode identified, be offset with the position that prevents light-emitting diode.Yet said method only is that the outline for light-emitting diode positions, and does not consider the particular location of light-emitting diode chip for backlight unit in light-emitting diode.If skew has occured in the position of light-emitting diode chip for backlight unit in light-emitting diode, so above-mentioned localization method then produces error inevitably.
Summary of the invention
In view of this, be necessary to provide a kind of location comparatively accurately localization method and the used suction nozzle of said method of light-emitting component.
A kind of localization method of light-emitting component, it may further comprise the steps:
A light-emitting component is provided, and described light-emitting component comprises substrate and is arranged on led chip on the substrate, and the surface of led chip is provided with pilot pin;
A suction nozzle is provided, comprises hollow tube and image sensor, hollow tube has an opening, when light-emitting component is attached to opening at hollow tube, vacuumizes to produce negative pressure in the inside of hollow tube light-emitting component is attached to suction nozzle.Image sensor is arranged at the inside of hollow tube, and described image sensor is by the position of the location positioning led chip of the pilot pin on detection led chip surface.
A kind of suction nozzle is used for the crawl object.Described suction nozzle comprises a hollow tube, and hollow tube has an opening, by vacuumize to produce negative pressure to hold object near opening in hollow tube inside.Described suction nozzle further comprises an image sensor, and described image sensor is arranged on the inside of hollow tube and determines the position of object.
In the localization method of light-emitting component, by an image sensor being set in suction nozzle inside and at the upper surface of led chip pilot pin being set, when using suction nozzle crawl light-emitting component, described image sensor can be determined by pilot pin the position of led chip, thereby makes the location of light-emitting component in the piece process comparatively accurate.

Following embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Referring to diagram, the localization method of light-emitting component of the present invention is further detailed.
See also Fig. 1, a light-emitting component 10 is provided.Described light-emitting component 10 comprises substrate 11 and is arranged on led chip 12 on the substrate 11.In the present embodiment, be provided with a columned groove 13 on the described substrate 11.Led chip 12 is arranged on the bottom of groove 13.The upper surface of led chip 12 is provided with the location that pilot pin 14 is used for subsequent process led chip 12.As required, can further fill transparent encapsulation material 15 in the described groove 13, to cover led chip 12.Described transparent encapsulation material 15 can be doped with fluorescent material, be used for to absorb the light that led chip 12 sends and the light that converts thereof into another wavelength.
Please in the lump referring to Fig. 2, provide a suction nozzle 20.Described suction nozzle 20 comprises hollow tube 21, and hollow tube 21 has an opening 22, is used for adsorboluminescence element 10.When light-emitting component 10 is attached on the opening 22 of hollow tube 21, thereby vacuumize light-emitting component 10 to be attached on the suction nozzle 20 producing negative pressure near the opening 22 in the inside of hollow tube 21.Please in the lump referring to Fig. 3, as required, described suction nozzle 20 further comprises the retainer ring 23 that is arranged on hollow tube 21 inside.Described retainer ring 23 is fixedly connected with hollow tube 21 by fixed leg 24, still remains with gas channel 25 between retainer ring 23 and the hollow tube 21 for the air flow stream mistake in the vacuum thereby make.
Suction nozzle further comprises an image sensor 30, and it is arranged on the inside of hollow tube 21.The position of led chip 12 is determined in image sensor 30 is arranged on the pilot pin 14 on led chip 12 surfaces by detection position.In the present embodiment, described image sensor 30 is charge coupled cell (charge couple device, CCD), and it is arranged on the retainer ring 23.As required, also further be provided with layer of transparent glassy layer 31 between image sensor 30 and the retainer ring 23, described transparent glass layer 31 impacts for the camera lens of the foreign material such as the dust that prevents use procedure or fines to image sensor 30.
In the position fixing process of above-mentioned light-emitting component, the inside of suction nozzle 20 will be built in the image sensor 30.When utilizing 30 pairs of light-emitting components 10 of image sensor to position, described image sensor 30 is not that outline to whole light-emitting component 10 positions, but led chip 12 positions in the light-emitting component 10 for being arranged on.In this case, even led chip 12 has skew in the position of light-emitting component 10, above-mentioned localization method still can be placed to accurately position with led chip 12 exactly, and does not need the process through overcorrect.
Be understandable that, the hollow tube 21 of suction nozzle 20 can be made by transparent material, thereby thereby the inside that makes extraneous light enter hollow tube 21 makes image sensor 30 carry out effectively identification to the position of led chip 12.In addition, light source can also be set in the inside of hollow tube 21 illuminating light-emitting component 10, thereby make image sensor 30 carry out effectively identification to the position of led chip 12.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection range that all should belong to claim of the present invention with distortion.
