Abstract
The utility model relates to an LED pretesting machine, comprising a loading fixture, a movable base, a test probe, a control system, an optical signal receiving head, and an optics tester. The loading fixture is fixed on the movable base. The test probe can be inserted into the loading fixture. The optical signal receiving head is disposed above the loading fixture. The optics tester is connected with the optical signal receiving head. The control system controls movement of the movable base and the test probe. The test probe tests an LED in the loading fixture under control of the control system. Optical properties of the LED are transmitted to the optics tester through the optical signal receiving head. According to a test result analyzed and displayed in the optics tester, amount of adhesive dispensing in adhesive dispensing steps and ratio of silica gel and fluorescent powders are adjusted, thereby improving a yield rate.
Description
Technical field
The utility model relates to a kind of instrument of LED optic test, relates in particular to a kind of LED to be baked the LED before measurement machine of testing before single of cutting.
Background technology
At present, the production process of LED comprises successively a glue, toasts, is cut into single and test, because operating personnel need to determine whether the ratio of what of glue step mid point glue amount and silica gel and fluorescent material is suitable according to the test result of testing procedure, if some glue amount is improper, can have influence on the characteristic of LED optical color coordinate, but experience baking in the middle of some glue step and the testing procedure and be cut into single step, so just have general 5 ~ 6 hours time interval, if need a large amount of productions, waits for too long; Produce line for quantity-produced, can't inspect by random samples in process of production, if test finds that defective products is arranged, then in before this step all there is improperly problem of a glue amount in (some glue, toast, be cut into single) LED product of processing, loses larger.
Therefore, how providing a kind of LED before measurement machine that just can carry out optic test to LED in baking, before being cut into single step is the technical problem that those skilled in the art need to be resolved hurrily.
The utility model content
The utility model provides a kind of LED before measurement machine, in baking, LED is carried out optic test before being cut into single step, thereby improves the yield of product and saves the operating time.
For solving the problems of the technologies described above, the utility model provides a kind of LED before measurement machine, comprise loading tool, movable base, test probe, control system, optical signalling Receiver and optical tester, described loading tool is fixed on the described movable base, described test probe can plant with described loading tool in, described optical signalling Receiver places described loading tool top, described optical tester links to each other with described optical signalling Receiver, and described control system is controlled the motion of described movable base and test probe.
Preferably, described control system is controlled the motion of described movable base directions X and Y-direction.
Preferably, described control system is controlled the motion of described test probe Z direction.
Preferably, the shape of described loading tool is complementary with the shape of putting the led support after glue is finished.
Compared with prior art, the utlity model has following advantage: described test probe is tested the LED that is arranged in described loading tool under the control of described control system, the optical characteristics of LED is passed to described optical tester by described optical signalling Receiver, according to the test result that analyze to show in the described optical tester ratio of what and silica gel and fluorescent material of a glue step mid point glue amount is adjusted, thereby improved the production yield.
