Abstract
The invention relates to a vertical testing scheme of a light emitting diode, which comprises the steps of: firstly, screening the light emitting diode through a vertical vibration disk to ensure that the light emitting surface of the light emitting diode upwards enters the most front end of the vibration disk; secondly, sucking the vertical light emitting diode from the most front end of the vibration disk through a feeding device, placing in a suction nozzle of a rotary working table, sucking and attaching the light emitting diode on the suction nozzle from the lateral side by the suction nozzle in vacuum; and finally, clamping a pin of the light emitting diode from the lateral surface by a horizontally clamped probe, electrifying, and detecting. The testing mode is consistent with the testing mode of other types of light emitting diodes, thus a testing device of the light emitting diode with a lateral light emitting is better exchanged with testing devices of other types of light emitting diodes.
Description
Technical field
The present invention relates to a kind of LED test scheme, further relate to a kind of through changing the testing scheme of light emitting diode placement location.
Background technology
Several aspects important in the optical parametric of LED are exactly: luminous flux, luminescence efficiency, luminous intensity, light distribution, wavelength.Luminescence efficiency has characterized the energy conservation characteristic of light source, and this is an important indicator weighing modern light source performance.Therefore,, must test by diode before dispatching from the factory diode.
The testing scheme of existing market upside light emitting-type patch light-emitting diode all is by suction nozzle light emitting diode to be adsorbed on the disk; Then disk integral body is pressed down; The pin of light emitting diode is contacted with following probe assembly; Thereby make the light emitting diode electrified light emitting, light emitting diode is tested with the pick-up unit that install the side.
The shortcoming of existing scheme is, the patch light-emitting diode that this kind testing scheme can only the offside light emitting-type is effective, can't test for the light emitting diode that accounts for the very big top emission type of the market share.
Summary of the invention
In view of above content, be necessary to provide a kind of compatibility test scheme of testing side and top light emitting diode simultaneously.
The present invention provides a kind of led of side view type vertical testing scheme, and this scheme comprises:
At first: through upright removing from mould vibrating disc light emitting diode is screened, make side light-emitting diode (led) light-emitting area found the entering vibrating disc up foremost;
The side light-emitting diode (led) that will stand through feeding device is then put in the suction nozzle of rotation work dish from vibrating disc sucking-off foremost, and vacuum is adsorbed light emitting diode from the side by suction nozzle and is close on the suction nozzle;
Through the probe of level clamping, clamp the pin of side light-emitting diode (led) from the side at last, energising, detection.
The present invention puts into suction nozzle through side light emitting-type patch light-emitting diode is being stood; Make side light emitting-type patch light-emitting diode light emission direction up; Thereby well make it consistent, thereby the interchangeability of checkout equipment of checkout equipment and the top emission type light emitting diode of side light-emitting diode (led) is strengthened greatly with the test mode of top emission type light emitting diode.
Compared with prior art, the invention has the advantages that:
Because this kind test mode is consistent with the test mode of other types light emitting diode, so can make side light emitting-type testing apparatus and the fine exchange of other types LED test equipment.
Combine embodiment that the present invention is done further description with reference to the accompanying drawings.
Description of drawings
Fig. 1 is the process flow diagram of the vertical testing scheme of light emitting diode of the present invention.
Embodiment
See also Fig. 1, the vertical testing scheme of a kind of light emitting diode of preferred embodiment provided by the present invention, this scheme comprises:
At first: through side light emitting-type vibrating disc light emitting diode is screened, make side light-emitting diode (led) light-emitting area found the entering vibrating disc up foremost;
The side light-emitting diode (led) that will stand through feeding device is then put in the suction nozzle of rotation work dish from vibrating disc sucking-off foremost, and vacuum is adsorbed the side light-emitting diode (led) from the side by suction nozzle and is close on the suction nozzle;
Through the probe of level clamping, clamp the pin of side light-emitting diode (led) from the side at last, energising, detection.
The present invention is primarily aimed at the improvement that the LED test scheme is carried out; The above is merely preferred embodiment of the present invention; Non-so promptly limit to claim of the present invention; So the simple and easy variation and the equivalent transformation of doing with instructions of the present invention and graphic content such as all should be contained in the claim of the present invention.
