Problems solved by technology

But in this way, it is inevitable that there will be mistakes in the human judgment of the tester
Moreover, the tester cannot quantify the degree of luminescence of the LED, and it is not easy to define the standard brightness range of a good LED.
On the other hand, this test method will also increase the time of assembly in the production line and the consumption of the fixture, thereby increasing the production cost

Abstract

The invention provides a device for automatically testing a light-emitting diode and method. The device comprises a testing tool, a tested object setting place, a measuring device and a power supplying device. The testing tool comprises a sensitization module. The tested object setting place is used for setting the tested light-emitting diode and electrically connected with the power supplying device to provide a fixed voltage for the light-emitting diode. The measuring device is used for automatically testing the character variation of the sensitization module in the testing tool to judge whether the function of the light-emitting diode is normal or not.

Description

technical field [0001] The invention relates to an automatic testing device, in particular to an automatic testing device capable of automatically testing the quality of light-emitting diodes. Background technique [0002] In today's life, the use of light-emitting diodes is more and more popular. In the case of large output of light-emitting diodes, it is very important for the production line to test whether the function of light-emitting diodes is normal and fast. In the prior art, in the manufacturing production line, to test whether the LED is normal, it is usually after a fixed voltage is given to the LED, and then the human eye is used to observe whether it emits light or the brightness of the light to determine whether the function of the LED is not. normal. However, in this way, it is inevitable that there will be mistakes in the human judgment of the testers. Moreover, the tester cannot quantify the luminous intensity of the LED, and it is difficult to define th...
