Description

Technical Field

[0001] The utility model relates to the technical field of diode detection, in particular to a detection device for light emitting diode production. Background Art

[0002] A diode is an electronic device made of semiconductor materials. It has the property of unidirectional conductivity, that is, when a forward voltage is applied to the anode and cathode of the diode, the diode is turned on, and when a reverse voltage is applied to the anode and cathode, the diode is cut off; therefore, the conduction and cutoff of the diode are equivalent to the connection and disconnection of a switch.

[0003] The prior art can refer to the Chinese patent with the authorization publication number CN219245623U, which discloses a diode detection mechanism, including a base, a frame and a detection structure, wherein the frame is fixedly arranged on the top surface of the base, and the detection structure is detachably arranged on the surface of the frame, and the detection structure is provided with at least two groups, and the detection structure includes a detection meter, a positive electrode, a negative electrode, a first connecting wire and a second connecting wire, but the detection mechanism still has shortcomings when used:

[0004] First, there is no way to drive the diode to vibrate when the diode is powered on for testing, so it is impossible to determine whether the diode can emit light stably during vibration;

[0005] Secondly, it is impossible to inspect the appearance of the diode, and it is impossible to determine whether the appearance of the diode is intact, which has poor practicality.

[0006] Therefore, a detection device for light emitting diode production is now provided. Utility Model Content

By setting a detection box and a vibration component, it can be detected whether the diode can stably emit light under vibration. By using the provided rotating mechanism, movable frame and visual detection component in coordination, it can be detected whether the appearance of the diode is intact. The utility model has good practicality, overcomes the deficiencies in the prior art, and effectively solves the problem that the existing diode detection mechanism has no pair to drive the diode to vibrate when the diode is powered on for testing, thereby failing to determine whether the diode can stably emit light during vibration and failing to detect the appearance of the diode, failing to determine whether the appearance of the diode is intact, and having poor practicality.
