Abstract

The present invention relates to an intelligent testing system, method and medium of light-emitting diodes, belonging to a testing device for light-emitting diodes, including a frame, at least two sets of storage modules arranged in parallel on the frame, a testing module, a feeding module and The control terminal, the test module includes a third linear movement module arranged on the frame, a fourth linear movement module is arranged on the third linear movement module, and a fourth linear movement module is arranged on the fourth linear movement module. The third moving block, the two sides of the third moving block are provided with a second moving cylinder, the output end of the second moving cylinder is provided with a test platform, and a plurality of probes are arranged on the test platform, and the probes Used to contact the positive and negative terminals of the LED so that the probe can communicate with the internal components of the LED. The faults of the internal parts of the light emitting diode can be quickly detected through the probe, thereby screening out unqualified products and improving the authenticity rate of the miniature light emitting diodes when they leave the factory.

Description

technical field

[0001] The invention relates to the field of light-emitting diode testing, in particular to an intelligent testing system, method and medium for light-emitting diodes. Background technique

[0002] With the country's policy and financial support for the semiconductor industry, as well as the continuous increase in technological investment and development of domestic semiconductor industry manufacturers, the proportion of my country's semiconductor market in the world's semiconductor market has continued to expand, and the process of domestic substitution of semiconductor products has gradually accelerated. Light-emitting diodes, referred to as LEDs, as one of the most basic light-emitting devices, play an indispensable role in the field of display lighting in today's society. With the development of society, in the field of display and lighting, people have put forward higher requirements for LED devices. The ideal LED device should be the unity of external ...
